Association of -971 G/A cholesteryl-ester transfer protein gene polymorphism with lipid profile in primary hyperlipidemia
Hassanzadeh T, Barkhordari A,
Volume 70, Issue 7 (10-2012)
Abstract

Background: Coronary heart disease (CHD) is a leading cause of death worldwide and hypertriglyceridemia and hypercholesterolemia are major risk factors for the disease. Considering the role of hyperlipidemia as the underlying cause of cardiovascular mortalities and morbidities, and the limited and conflicting results of studies on CETP gene polymorphisms in Iran, we aimed to study -971 G/A polymorphism of cholesterol ester transfer protein gene in patients with primary hyperlipidemia.
Methods: In this case-control study performed in Hamadan University of Medical Sciences (from May 2010 to April 2011), we recruited 200 patients with primary hyperlipidemia (total cholesterol >250 mg/dl and/or triglyceride >200 mg/dl) as the cases and 200 healthy individuals with normal cholesterol and triglyceride as the control group. Gene segments were replicated by polymerase chain reaction (PCR) and -971 G/A polymorphism genotypes were identified by RFLP technique. Subsequently, plasma CETP activity was measured enzymeatically by a kit in a fluorescence spectrometer.
Results: The allele and genotype frequencies were not significantly different (P>0.05) between the two groups (in the control group: AA 24%, GA 47% and GG 28.5% and in the case group: AA 18%, GA 51% and GG 31%). In the case group, homozygous individuals with A alleles (AA genotype) had greater cholesterol and HDL-c concentrations than those with other alleles (GG and GA). In both cases and controls, individuals with AA genotype had lower CETP concentrations.
Conclusion: We conclude that -971 G/A polymorphism in CETP gene promoter can affect lipid profile and alter CETP activity.

Volume 70, Issue 12 (3-2013)
Abstract

Background: Amphotericin B Deoxycholate (ABD) has been the best therapeutic agent for treatment of most systemic fungal infections. However, untoward adverse effects like nephrotoxicity may limit its appropriate therapeutic use. We studied administration of fat emulsion early after infusion of ABD to evaluate its effects on ABD-associated nephrotoxicity.
Methods: This study was a randomized clinical trial. Patients with fungal infections admitted in Amir-Alam and Imam-Khomeini University Hospitals, Tehran, Iran, entered the study during 1390- 1391. The patients were randomized to intervention and control groups. In both groups, patients received 1mg/kg/day ABD in dextrose 5%. In intervention arm, the patients additionally received intralipid 10% daily that was started as soon as possible within one hour after infusion of ABD. ABD-associated nephrotoxicity (a minimum 50% increase in baseline serum creatinine to a minimum of 2mg/dl), daily serum creatinine changes during first two weeks of treatment and some other relevant indices of renal function were compared between groups. ABD-related hypokalemia was also compared as an additional target.
Results: Thirty one patients entered the study. ABD-associated nephrotoxicity and values of other relevant indices of renal function were not different between intervention and control groups (P>0.05). Daily changes in serum creatinine level within first two weeks of treatment in both groups were not also statistically different (P=0.62). Furthermore, ABD-related hypokalemia was not significantly different between groups (P=0.47).
Conclusion: Administration of intralipid 10% early after infusion of ABD in dextrose 5% does not have any effect in decreasing ABD-associated nephrotoxicity. Moreover, it does not have any significant effect on ABD-related hypokalemia.

Volume 71, Issue 4 (7-2013)
Abstract
Background: The purpose of this study was evaluation of risk factors of peripheral artery disease (PAD) and effective markers on it.
Methods: This descriptive-analytical study was done during 2010-2011 in the surgical units of Khorramabad Shohada Hospital. Fifty patients who had symptoms of PAD undergoing CT angiography and biochemical markers for them were measured. The investigated variables were family history, site of arterial obstruction, underlying diseases, smoking history, physical activity and stress level. A control group was considered for the study. The comparison was made between these two groups.
Results: Aging showed a significant role in prediction of PAD (70% sensitivity and 64% specificity). Homocysteine had the highest sensitivity (80%) in prediction of PAD, compared with other biomarkers. CRP (74% sensitivity) was the best marker that had positive predictive value for PAD. Fasting blood sugar (FBS) showed a significant role in prediction of true positive cases of PAD (72% sensitivity and 74% specificity). HbA1C with 68% sensitivity and 64% specificity and TG with 50% sensitivity and 44% specificity could be considered as factors related with PAD.
Conclusion: The levels of C-Reacative protein, homocysteine, and FBS were correlated with PAD, HbA1C and TG levels were associated with PAD, but lower than the previously named markers. In this study a significant relationship between lipoprotein levels and PAD was also observed. PAD was associated with sex and age.

Volume 71, Issue 9 (12-2013)
Abstract
Background: Androgenetic alopecia (AGA) is the most common type of progressive balding that appears with early loss of hair, chiefly from the vertex. There has been significant relationship between AGA with coronary artery disease and related risk factors, such as hypertension in some studies. The aim of this study is to investigate the association between androgenetic alopecia with hyperlipidemia.
Methods: This cross-sectional study was performed on 112 patients with vertex type AGA (in male grade 3 or higher Hamilton- Norwood scale, and in female grade 2 or higher Ludwig scale) (study group) and 115 persons age and sex matched, with normal hair status (Normal group). None of participants had diabetes mellitus, hypothyroidism, liver disease, kidney disease and none of them had history of smoking and using drugs with effect on serum lipids. They were 20-35 years old and their body mass index were 20-30. Blood samples were obtained following 12 hours fasting status and serum levels of triglyceride (TG), cholesterol, high-density lipoprotein (HDL) and low-density lipoprotein (LDL) were determined using standard laboratory methods. Total cholesterol greater than 240 or TG greater than 200 or LDL greater than 160 or HDL less than 40 in men or HDL less than 50 in women were considered hyperlipidemia.
Results: In androgenetic alopecia group 46.4% and 47% of normal group were female. Mean (±SE) of total cholesterol (172.4±3.1, 148.8±3.1, P< 0.001), TG (133.6±5.5, 88.3±4.3, P< 0.001), LDL (96.4±2.9, 84.9±2.7, P= 0.004) and HDL (54.9±2.0, 45.5±0.9, P< 0.001) in AGA patients were higher than normal group. %46.4 of patients and %52.2 of controls had hyperlipidemia. Relationship between AGA with hyperlipidemia was not significant (P> 0.05).
Conclusion: The findings showed that there is no relationship between AGA and hyperlipidemia. Regarding to high levels of total cholesterol, LDL and triglyceride in AGA patients, it seems that, AGA increases risk of coronary heart disease. To determine a definite association between AGA and hyperlipidemia more studies are recommended.

Volume 73, Issue 2 (5-2015)
Abstract
Background: Rupture of uterus is a catastrophic complication associated with significant maternal and fetal morbidity and mortality. The prevalence of an unscarred uterine rupture is very rare. Although the most important complication of dilatation and curettage is perforation of uterus, dilatation and curettage is not introduced as an important cause of uterine rupture. Case presentation: Here we present a case of uterine rupture in a pregnant woman that was admitted in Tehran General Women Hospital, in December 2014, with reducing fetal movement in her 41th weeks of pregnancy. She did not have any risk factors for rupture of uterus including cephalo-pelvic disproportion and polyhydramnios, also there was no history of uterine surgery such as myomectomy and uterine abnormality repair. A term dead male neonate was delivered by cesarean section due to arrest of descending in stage 2 of labor. The baby weighed 3400 gr and had anomaly in ears, larynx, uvula and soft palate. Its chromosomal study depicted both trisomy and monosomy for chromosome 13 and 21. Mother had a history of illegal curettage and trauma to the uterus in her first pregnancy two years ago. She did not say to us this history and abortion during admission. After cesarean section we saw that in the left side of the posterior wall of uterus was ruptured and baby was died. At surgical exploration, moderate hemoperitoneum was evident. Fetus was already dead at the time of extraction. Total estimated blood loss was 100 ml, the patient was transfused with two units of packed cell. The woman was discharged on the fifth postoperative day in good condition. Conclusion: Effective contraception and safe curettage can reduce maternal mortality and morbidity. Also special attention to a history of curettage to predict uterine rupture is critical.

Volume 73, Issue 7 (10-2015)
Abstract

Background: Low density lipoprotein (LDL) particles have shown to be heterogeneous structures with distinctive electrical charges. Alteration in the fatty acids content of the LDL particles is known to affect their structural features, electrical charges, and ultimately physiologic properties and, in this way, may play a role in the pathology of coronary artery disease (CAD). On the basis of evidences, in the present study, the relationship of fatty acids content of LDL particles and their electrical charge was assessed in patients with CAD in comparison with control subjects. Methods: In the current case- control study, from subjects who referred to the Mostafa Khomeini Hospital in Ilam during a time period from December 2013 to October 2014, 40 CAD patients and 40 control subjects were selected based on the clinical and angiographic parameters. The fatty acids content and electrical charges of LDL particles were measured by using a gas chromatography system, equipped with a flame ionization detector GC-FID, Acme 6000 M (Young Lin Co., Korea) as well as a Zetasizer (Malvern Instruments Ltd., UK), respectively. Results: In the present study, CAD patients and control subjects were matched for age, sex, and body mass index (BMI). The electrical charge amounts of LDL particles in the patients group was significantly lower than those in the control subjects (P= 0.0001). There was an inverse correlation between the electrical charge amounts of the LDL particles and the saturated fatty acids as well as linoleic acid contents of them in CAD patients group. However, we found a direct correlation between the unsaturated fatty acids (monounsaturated fatty acids and some of the polyunsaturated ones) content of the LDL particles and their electrical charge amounts (P= 0.02). Conclusion: Results of the present study demonstrated that the increased saturated fatty acids as well as the linoleic acid contents of the LDL particles are associated with decreased electrical charge amounts of these particles and this situation may engage in pathogenesis of CAD.

Volume 74, Issue 1 (4-2016)
Abstract

Background: Many studies have reported the effect of metronidazole on reducing blood lipids in different ways, but there is no comprehensive estimation about its effect. Therefore, this study aimed to determine the effect of metronidazole on reducing blood lipid by meta-analysis method.

Methods: This is a systematic review based on the reliable local and international websites including SID, Magiran, Iranmedex, ISI, Pubmed and Scopus. The keywords used for searching were metronidazole, blood lipid, cholesterol, triglyceride, low density lipoprotein (LDL) and height density lipoprotein (HDL). All articles published until the end of March, 2015, about the effect of metronidazole on blood lipids reduction which met the inclusion criteria were reviewed. Three independent reviewers checked studies for quality and eligibility and finally extracted the data. The collected data were analyzed by meta-analysis method (random effects model) and by means of Stata, ver. 11.1 (College Station, TX, USA) with a significance level of less than 5%.

Results: In 10 researches, 292 people had been studied and after taking metronidazole, the calculated amount of reduction in blood lipids was 11% (95% CI: 6%-16%) for cholesterol, 14% (95% CI: 4%-24%) for triglyceride and 8% (95% CI: 1%-15%) for low density lipoprotein (LDL) which was statistically significant (P= 0.001). The amount of increase in high density lipoprotein (HDL) was also calculated to be 1% (95% CI: 1%-2%) which was not statistically significant (P= 0.08).

Conclusion: The results of this study showed that, using metronidazole leads to decrease in the amount of cholesterol, triglyceride and low density lipoprotein (LDL) but it seems that it has not any effect on the increase in high density lipoprotein (HDL).

Volume 74, Issue 9 (12-2016)
Abstract

Background: Smoking is a harmful habit and saliva is the first fluid that is exposed to cigarette smoke as a source of oxidant and peroxidant agent. Salivary antioxidant system plays an important role in its anti-cancer potential. Uric acid has a role as antioxidant in the body and could increase plasma antioxidant capacity and has a specific role as inhibitor on radicals and peroxidant agent. Therefore, the aim of this study was to evaluate indicators of oxidative stress or malondialdehyde (MDA) as an important parameter of lipid peroxidation and total antioxidants capacity in smokers and non-smoking persons.

Methods: In this case-control study which was conducted in clinical biochemistry labratory, Mazandaran University of Medical Sciences on Spring 2016. The sample on salivary fluids was collected by spitting method in tubs from 50 smokers (cases group) and nonsmokers (controls group) after all night fasting. As soon as saliva was collected, at the first step total whole salivary fluids were centrifuged and the superior parts were transferred in a tub and stored at -80 ℃ until analyzed. Total antioxidant capacity (TCA) of their saliva was evaluated by Ferric reducing ability of plasma (FRAP) method, lipid peroxidation parameter (MDA) with thiobarbituric acid (TBARS) and uric acid by calorimetry (uricase) methods. The data were analyzed via SPSS software and independent t-test was used to compare the two groups.

Results: Indicators of oxidative stress, in the case group was 1.17±0.29 nmol/ml significantly higher than compared to control group with 0.91±0.16 nmol/ml. TCA in the case group was 220.66±39.68 μmol/l compared to control group 272.26±40.64 μmol/l was significantly lower (P< 0.05).

Conclusion: The result of this study indicates that smoking can reduce total antioxidant capacity and increase lipid peroxidation parameters. In addition, duration of cigarette using has destructive effects on body that it can lead to several diseases. The important thing is to keep trying to quit smoking. For smokers who are willing to quit, it would be recommend that smokers be managed with a combination of behavioral support and pharmacologic therapy.

Volume 75, Issue 4 (7-2017)
Abstract
Background: Paraoxonase-1 (PON1) is one of the most important enzymes for removal of the free radicals, and the main protective factor for lipoproteins against oxidative agents. The purpose of this study was to investigate the effects of eight weeks’ rope training on paraoxonase-1 enzyme, insulin resistance and lipid profiles in inactive overweight and obese girls.
Methods: This quasi-experimental study was conducted in Iranian Azarbaijan Shahid Madani University of Tabriz, from November 2016 to January 2017. In this study, 20 healthy overweight and obese in-active girls (20-25 Yr) volunteered and randomly assigned into exercise (n=10) and control (n=10) groups. Exercise protocol was rope training was 8 week for 4 day per week in 45 minute per day. Some anthropometric indexes of subjects were measured before and after exercise. A fasting blood sample was collected as pre-test and post-test, followed by 48 hours of physical inactivity to measure serum levels of PON1 enzyme, Insulin, lipid profiles and other blood variables. Analysis of the data was performed by paired and independent samples t-tests by using the SPSS software, version 20 (IBM, Armonk, NY, USA). The criterion of statistical significance was set as P<0.05.
Results: The paired samples t-test results showed that after exercise intervention, in exercise group, the values of all variables (except low-density lipoprotein) were significantly changed. Also, to compare with control group, the values of PON1 enzyme (P=0.024) and maximum oxygen consumption (P=0.006) significantly increased and insulin resistance index (P=0.028), triglyceride (P=0.046) and body fat percent (P=0.001) were significantly decreased (P<0.05).
Conclusion: The results of this study showed that performing rope training for 8 weeks induced positive changes in paraoxonase-1 enzyme, insulin resistance index, maximum oxygen consumption and some lipid and anthropometric indices in overweight and obese young girls. Therefore, according to these results, rope training, as an aerobic activity it can be useful for all people especially in overweight and obese to control blood fats, body composition and prevent diseases due to obesity such as cardiovascular disease.

Volume 75, Issue 11 (2-2018)
Abstract
Background: The prevalence of diabetes mellitus due to existence of various factors is growing rapidly. The insulin resistance phenomenon is one of the main underlying causes of this disease, due to various reasons such as a decrease in serum levels of vitamin D3. In this study, we evaluated the relationship between plasma level of vitamin D3 and some other main plasma factors.
Methods: This clinical trial study carried out on type 2 diabetes mellitus subjects who referred to diabetes clinic of Baqiyatallah Hospital in Tehran city during June to September 2016. First demographic data of all patients were collected. Then the blood samples for evaluation of blood glucose, HbA1c, triglyceride, cholesterol, HDL, LDL and vitamin D3 were obtained. Based on plasma level of vitamin D3, diabetic subjects were divided into two separate treatment groups (with and without vitamin D3 deficiency) and then above-mentioned factors were compared between these two groups. Afterward, in group with vitamin D3 deficiency, treatment by vitamin D3 triggered (50000 unit per week for eight weeks orally) until plasma level of vitamin D3 reached above 30 ng/mL. Then, treatment continued by vitamin D3 (50000 Unit per week orally) and calcium (1.5 g/day PO) until 60 days. Finally, the patients were evaluated about fasting blood glucose, HbA1c, HDL, LDL and blood pressure.
Results: In total, 187 subjects (99 men and 88 women) were evaluated in this study. Total hypovitaminose incidence was 0.65% which was higher in subjects with higher body mass index (BMI). Serum content of vitamin D3 and calcium, significantly changed the values of fasting blood sugar (FBS), HbA1c, HDL and TG, but has no significant effects on other factors.
Conclusion: Our results clearly revealed that hypovitaminose vitamin D3 is one of the main factors that can leading to rise in plasma glucose and dyslipidemia occurrence. Also, our data are demonstrated that treatment by vitamin D3 and calcium can modify fasting blood glucose and dyslipidemia in type 2 diabetes mellitus subjects.

Volume 76, Issue 7 (10-2018)
Abstract
Background: Metabolic syndrome (MetS) is characterized by a combination of cardio-metabolic risk factors. Given that genetic factors have been shown to contribute to individual susceptibility to MetS, the identification of genetic markers for disease risk is essential. Recent studies revealed that rs780094 and rs1260326 of glucokinase regulatory gene (GCKR) are associated with serum triglycerides, plasma glucose levels and metabolic syndrome. The aim of this study was to investigate associations of GCKR gene variants with metabolic syndrome and its components.
Methods: This case-control study was conducted from April to August 2017. In this study, 8710 adults (3522 males and 5188 females), over 19 years, were randomly selected from the Tehran Lipid and Glucose Study (TLGS) population. Based on joint interim statement (JIS) criteria, the subjects were divided into two groups: case and control. Genotyping was performed by HumanOmniExpress-24 v1.0 BeadChips (Illumina, San Diego, CA, USA).
Results: Allele frequencies were in conformity with Hardy-Weinberg equilibrium. Comparisons of allele frequencies by the Chi-square test revealed that frequencies of TT genotype of both polymorphisms were significantly higher among patient group than healthy group. Logistic regression analysis with adjustment for age, gender and CRP revealed that the GCKR polymorphisms (rs1260326: odds ratio 2.7, 95% CI 1.6-4.6, rs780094: odds ratio 2.5, 95% CI 1.5-4.2) were significantly associated with MetS. Frequency of TT genotype was more in persons who had C-reactive protein (CRP) levels above 3 mg/l. The minor T allele of both polymorphisms was significantly associated with increases in the blood serum concentration triglyceride and to a decrease in fasting plasma glucose levels.
Conclusion: The results of our study indicated that, rs780094 and rs1260326 common polymorphisms of the GCKR gene were associated with serum triglycerides levels, fasting plasma glucose levels, and metabolic syndrome in a sample of the Tehranian population (TLGS), as it was already confirmed the inverse effect of this polymorphisms on triglycerides and glucose levels in previous studies.

Abstract
Background: Disruption of lipid metabolism threatens human life in all countries with different percentages and causes cardiovascular disease. Reducing physical activity and eliminating some of the food medications have exacerbated these complications. The aim of this study was to investigate the effect of ginger supplementation on the lipid profile and body composition of obese women following Pilates exercises.
Methods: This semi-experimental study was carried out at the Medicinal Plants Research Center of Ilam University of Medical Sciences, Iran, from September to December 2012. In this study, 90 pregnant women with type 2 diabetes mellitus were randomly divided into three groups: complement, placebo and control (30 objects in each group). The exercise protocol includes a ten-week Pilates exercise. The supplement group consumed 2 grams of ginger powder daily for ten weeks. The placebo group used starch (placebo) capsules for these ten weeks. The control group did not take any supplement and did not have any activity at all. Blood samples were taken prior to physical activity and 48 hours after the end of 10 weeks Pilates training three sessions per week (30 sessions). In order to investigate intra-group changes, t-test and one-way ANOVA were used to compare the groups.
Results: The results showed that after 10 weeks of using zinc supplements following Pilates exercise training in pretest and posttest, increases in HDL levels and decreased TG, LDL, Tcol, body composition and body weight in obese women. Also, consumption of 10 weeks of ginger supplement after aerobic exercise training on TG (P=0.001), LDL (P=0.02), Tcol (P=0.05) and HDL (P=0.01) in obese women in supplement and placebo groups had a significant impact.
Conclusion: The results of this study showed that Pilates exercises with daily consumption of 2 grams of ginger supplement for 10 weeks caused a significant decrease in lipid profiles, body fat percentage, weight, and hip circumference.

Abstract
Background: Coronary artery disease today is a major contributor to mortality and morbidity from cardiovascular disease. The drug, interventional and surgical methods are used to treat coronary artery stenosis. Statins are the most commonly used drugs for stenosis and coronary artery disease. Low-density lipoprotein (LDL) The purpose of this study was to evaluate the effect of atorvastatin on LDL and C-reactive protein (CRP) reduction in patients.
Methods: This study was a systematic review and meta-analysis. Articles were selected using the keywords of atorvastatin, LDL, C-reactive protein (CRP) and reduction, and searches in Scopus, Google Scholar and PubMed databases from March 2003 to February 2018. For this purpose, all analytical, clinical trials, cross-sectional, and case-control studies were searched and collected in association with the efficacy of atorvastatin on low density lipoprotein and CRP.
Results: In the initial search, 90 papers were found and evaluated. Finally, 20 papers were analyzed. The studies were published. The total sample size was 21609 persons with an average sample size of 1080 in each study. Twenty studies were entered into the final analysis. The LDL-lowering rate was 51 mg/dl with atorvastatin (I2=98.48, P<0.001). Also, CRP reduction before and after administration of atorvastatin was   1.99 (0.96-3.03) and 0.76 (0.08-1.43), respectively. The results of meta-regression of age-related studies showed that LDL levels were low in studies with lower age, and LDL levels were low in studies with higher age. The results of a meta-regression study of atorvastatin in terms of body mass and the association of low-density lipoprotein with atorvastatin showed that in those with a higher body mass, low-density lipoprotein decreased.
Conclusion: According to the results, the use of atorvastatin reduces the amount of C-reactive protein (CRP). The rate of low density lipoprotein (LDL) reduction was better and faster in young and obese people. It is recommended that people have a proper diet and regular exercise in their daily schedule.

Volume 77, Issue 7 (10-2019)
Abstract
Background: Acute myeloid leukemia (AML) is blood and bone marrow malignancy. Low-density oxidative lipoprotein (oxLDL) is a pro-inflammatory factor that has free radicals in its structure. OxLDL levels are also rising in diseases such as diabetes, cardiovascular disease, and some cancers. Studies have shown that oxLDL and dyslipidemia are more common in patients with various cancers. This study aimed to evaluate the level of blood lipids and oxLDL in these patients with acute myeloid leukemia.
Methods: In a descriptive study, 36 patients who were diagnosed with acute myeloid leukemia from April 2016 to March 2017 were enrolled. This study was done in Shahid Ghazi Blood Department of Imam Reza Hospital, Tabriz University of Medical Sciences, Iran. Basic information including age, sex, type of disease, cause for referrals of the patients were collected. After obtaining informed consent from patients and 12 hours of fasting, 5 cc blood samples were sent to the Central Laboratory of Shahid Ghazi Hospital to measure the level of blood lipids including cholesterol, triglyceride, low density lipoprotein, high density lipoprotein (HDL), and oxLDL levels. Blood lipid and oxLDL levels were measured by automatic analyzer (Abbott Laboratories, Abbott Park, IL, USA) (ELISA method).
Results: 23 patients (54.8%) were male and 19 (45.2%) were female. The mean age of the patients was 44.06±14.48 years. The lowest age was 25 and the highest was 80 years. In the study, the mean serum cholesterol level was 147.64±42.28 mg/dl, the blood triglyceride was 183.28±79.34 mg/dl, the LDL was 84.89±26.35, and the HDL 29±14.51, the mean oxLDL was 1482.5±6031.85 ng/ml.
Conclusion: The results of this study indicate that dyslipidemia in patients with acute myeloid leukemia has not been evident. Concerning oxLDL, an oxidative stress factor involved in acute myeloid leukemia requires further investigation and studies.

Abstract
Background: Non-viral Nano carriers such as liposomes and cationic polymers based on engineered properties are regarded in gene delivery field. Although these carriers do not have weaknesses of viral vectors, but they are less efficient than viruses and they still need to be improved as favorable gene delivery carriers. Amongst non-viral carriers, cationic liposomes have been proposed for clinical applications, but limitations such as low nucleic acid transfer and endosome escape and conduction of plasmid to the nucleus have challenged their use in clinical trials. Therefore, the combination of liposomes and cationic polymers for nucleic acid transfer has been considered because this approach makes it possible to use the desirable properties of liposomes and polymers so that it is even suggested for the gene treatment of some diseases such as Parkinson's. In this study, a combination of liposomes and cationic polymers were used for the preparation of lipopolyplexes. This approach allows simultaneous utilizing of the desirable properties of liposomes and polymers.
Methods: This interventional-experimental study was conducted in the medical faculty of Mashhad University of Medical Sciences from April 2017 to February 2018. In this study, PEI-based lipopolyplex with a molecular weight of 25 and 10 kDa and a liposome-to-polymer ratio of 1:1 were combined with plasmid containing the GFP (Green Fluorescent Protein) marker. The physicochemical properties of the synthesized carriers such as size, cytotoxicity and gene transferability in human prostate cancer (PC3) cells were evaluated.
Results: The prepared lipopolyplex were 104 nm in size and all the lipopolyplexes were able to enhance transfection in the C/P=0.4 compared with its basic carriers (PEI and liposomes) alone, while showing less cytotoxicity than not manipulated liposomes. The results of this study suggest synthesized nanoparticles as nanocomposites for gene delivery purposes to different cells and in in-body studies.
Conclusion: The results of this study show that the lipopolyplex constructed from combination of PEI and liposomes can efficiently transfer the gene to the cell, while showing low cytotoxicity and appropriate size at the nano-scale. Therefore, this lipopolymer can be suggested for gene delivery purposes to different cells and in vivo targets.

Due to the high importance of the association between psoriasis and CKD which results in major side effects the aim of this study was to evaluation of CKD and associated factors in Psoriasis patients at Razi Hospital, Tehran, Iran.
Methods: This retrospective study was conducted as a cross-sectional descriptive and analytical study to evaluate the frequency of CKD and associated factors in psoriatic patients admitted to the Razi Hospital whose last time of admission was from June 2018 to January 2019. According to the K/DOQI guideline, CKD is defined as the GFR<60 mL/min/1.73 m² during at least a period of three months. GFR was calculated based on the MDRD formula. The sample size was equal to 265. The hospital documents of inpatients who have been admitted to Razi Hospital wards or follow-up clinics during 2017-2019 were used for collecting information and data. This information has been extracted based on the initial checklist for data collection. Collected data has been analyzed and performed by using SPSS 25 software.
Results: The study found that 18 (6.8%) of psoriasis patients had CKD. Patients were in the age range of 3.5-92 years, the majority of them were in the age range of 18.65–79.7 years. 171 (64.5%) patients were male and 94 (35.5%) were female. 41 (15.5%) patients had diabetes, 94 (35.5%) had hyperlipidemia and 41 (15.5%) had hypertension. History of NSAID, Methotrexate, Cyclosporine, Acitretin, Infliximab, and Adalimumab medication use among 9 (3.4%), 205 (77.4%), 56 (21.1%), 147 (55.5%), 30 (11.3%), and 28 (10.6%) patients were observed, respectively. Also, 54 (20.4%) had a history of phototherapy. 217 (81.9%) of the psoriatic patients had CPP (Chronic Plaque Psoriasis) and 48 (18.1%) had PP (pustular Psoriasis) and finally, 21 (7.9%) of the patients had psoriatic arthritis.
Conclusion: The prevalence of CKD was shown to increase by age. The other correlated factors are diabetes, hypertension, and hyperlipidemia. On the other hand, there was not found any significant correlation between drugs (NSAIDs, Methotrexate, Cyclosporine, Acitretin, Infliximab, Adalimumab) and CKD prevalence. There was also no significant correlation between phototherapy, psoriasis type and psoriatic arthritis, duration of psoriasis and CKD prevalence.

Abstract
Background: Diabetes mellitus is associated with an increased risk of cardiovascular disease. The effects of add-in Sodium-glucose cotransporter 2 (SGLT2) inhibitors to standard statin treatments in acute coronary syndrome (ACS) patients remains controversial. The effects of the empagliflozin treatment after percutaneous coronary intervention (PCI) on the lipid profile of patients with type 2 diabetes mellitus (T2DM) have not been investigated yet. This study aimed to evaluate the efficacy of empagliflozin administration on lipid profile in diabetic patients with ACS after PCI.
Methods: This randomized, double-blind, placebo-controlled trial study was conducted from March until December 2020 on type 2 diabetes patients who underwent PCI and were referred to the Golestan and Imam Khomeini Hospitals. 93 patients (56 males and 37 females, mean age of 56.55 years old) were included. The patients were randomly assigned into two groups of receiving empagliflozin (10 mg, once daily) or a matching placebo, in addition to standard therapies for 6 months. The changes in metabolic parameters including lipid profile before and 6 months after interventions were assessed.
Results: After treatment in placebo group the level of LDL-C (median 0.90 mg/dl to 0.82, P=0.008) and HDL-C (median 0.40 mg/dl to 0.35, P=0.090) were decreased, while in the empagliflozin group the levels of LDL-C (median 0.87 mg/dl to 0.96, P=0.875) and HDL-C (median 0.38 mg/dl to 0.48), P=0.007) increased. Treatment with Empagliflozin and placebo had no significant effect on changing the levels of total cholesterol, TG and eGFR (P>0.05). The weight loss and FBS reduction in the empagliflozin group were significantly higher than placebo (P=0.001 and P=0.048, respectively).
Conclusion: Our results showed that adding Empagliflozin to standard treatment compared with a placebo for 6 months significantly increased LDL-C and significantly increased HDL-C. Also, except for weight loss and FBS, Empagliflozin was not more effective in improving the metabolic parameters of diabetic patients after PCI compared with placebo, so it seems that the use of this drug in diabetic patients with ACS after PCI is not very cost-effective.

Abstract
Background: Due to the chronic nature of diabetes, children with type 1 diabetes are prone to a number of long-term complications. One of the most important complications of this disease is cardiovascular involvement due to atherosclerosis, which is directly related to the control of blood lipids. The use of probiotics may be effective in the process of complications in these patients by affecting fat metabolism. The aim of this study was to evaluate the effect of oral probiotics on lipid profiles in children with type 1 diabetes.
Methods: This study was conducted at Bahrami Children's Hospital from May 2018 to May 2019. In this single-blind randomized controlled clinical trial, 52 children with type 1 diabetes (aged 2 to 16 years) were studied. We created two groups of 26 individuals. The inclusion criteria were determined as follows: Proof of T1DM by history and information of children’s medical record. Also, the Exclusion criteria were determined in this way: Patients consuming probiotics in the last 4 weeks, gastrointestinal infections in the last 2 weeks, and presence of chronic underlying intestinal diseases. The probiotic group received, in addition to insulin therapy, a daily probiotic capsule for 90 days. The control group received only routine insulin therapy. Blood samples were taken to measure lipid profiles at the beginning and end of the trial.
Results: A total of 52 patients were included. The mean age of children was 9.3±2.9 (4 to 14 years). The mean age in the probiotic and control groups was 9.6±3.5 and 9.4±3.0 respectively. The results of this study showed that HDL-C was increased in the probiotic group compared to the control group, although it was not statistically significant (P>0.05). Also, changes in total cholesterol, LDL-C, and triglyceride were not statistically significant.
Conclusion: In this study, the use of oral probiotics for 90 days in children with type 1 diabetes did not have a significant effect on blood lipid profiles compared to the control group.

Volume 81, Issue 2 (5-2023)
Abstract
Background: birth weight is associated with neonatal mortality and morbidity .In recent studies, fetal growth is related to the risk of developing type two diabetes and cardiovascular disease in later life. The mother’s nutrition and metabolism are major determinants of fetal growth. Some complications of low birth weight are hypocalcemia, hypoglycemia, intrauterine death. Any substance or hormone that can cross the placenta may affect the fetal growth and birth weight, including the maternal lipid during pregnancy. The effect of gestational diabetes mellitus on neonatal birth weight has been documented. Lipids and amino acids usually are not considered in the clinical management of pregnancy because there is less known about the role of these nutrients in the well-being of the pregnancy. This study aimed to determine the relationship between levels of serum lipids in pregnancy and fetal birth weight.
Methods: This descriptive cross-sectional study was performed on 170 pregnant women referred to Kerman medical university clinics in Iran from March 2019 to April 2020. After explaining the objectives of the study and gaining informed consent from the individuals, the maternal lipid profile during the first trimester of pregnancy, was measured within the first visit through a sample taken from the maternal blood. Pregnant women were monitored during pregnancy, and the variables were measured (Age, BMI, weight, frequency of pregnancy, weight gain in pregnancy, lipid and blood glucose profiles). The results of the samples were analyzed using SPSS software, version 20 (IBM SPSS, Armonk, NY, USA).
Results: The results indicated that the newborn weight increases with an increment in the maternal blood cholesterol (P=0.001) and triglyceride (P=0.001) levels. In addition, it was found that the increasing HDL (P=0.867) and LDL (P=0.803) levels of the pregnant women’s blood, does not lead to the birth weight increase of the infants.
Conclusion: Results of our study generally indicate that triglyceride and cholesterol levels are related to fetal birth weight. Studies with high sample sizes are recommended to investigate all neonatal weight gain variables.

Abstract
Background: Fatty liver disease is the most common cause of chronic liver diseases in the world, which can cause cardiovascular diseases, so this research aims to scrutiny a period of intense intermittent sports activity and growth hormone perfuse on cardiac mitochondrial PGC1α and some indicators of oxidative stress in mice with liver damage.
Methods: The present research was conducted from September 2022 to March 2023 in the specialized physical training laboratory of Ferdowsi University of Mashhad. The statistical population was twenty one adult male Syrian mice with an average weight of twenty three grams. The sports activity protocol was adopted for fifty-six days using the special video recorder for rodents. The intense interval training program was carried out in the form of ten one-minute repetitions and two-minute active rest, so that the total daily training time for each person was thirty minutes.The vaccination protocol includes the daily vaccination of somatropin injected intraperitoneally.
Results: The PGC1α levels were significantly higher in both the HIIT (P=0.02) and H- GH (P=0.03) groups collationed to the witness team. Moreover, the levels of SOD were considerably increased, in both the HIIT (P=0.05) and H-GH (P=0.005) team s compared to the witness team. Moreover, the levels of MDA were considerably decreased, in both the HIIT (P=0.007) and H-GH (P=0.04) teams compared to the witness team. The decrease in insulin resistance was significant only in the HIIT (P=0.05) team compared to the witness team and slightly increased in the H-GH (P=0.36) team but was not considered. The difference between HIIT and H-GH team (P=0.03) was also significant.The proportion of ALT/AST in both HIIT (P=0.02) and H-GH (P=0.03) teams had a significant decrease compared to the witness team. LDL/HDL proportion evidenced considered decrement at just in the HIIT team (P=0.01).
Conclusion: Intense intermittent sports activity was able to produce a more optimal response compared to GH peptide in improving NAFLD-related indices. Injection of this hormone single may have adverse outcomes on some indexes of this abnormality.
