Abstract
Background and Aim: Lung cancer is the most common cancer among men around the world. The aim of this study was to determine the expression levels of CK19 mRNA marker in the affected patients’ peripheral blood.
Materials and Methods: Thirty patients with lung cancer (NSCLC type) were compared with 30 healthy controls. After taking peripheral blood samples and extracting total RNA, cDNA was synthesized and examined by Real-time RT-PCR technique. Then, the CEA antigen was measured by ELISA.
Results: The CK19mRNA was positive in 7 out of 30 lung cancer patients. Hence, its sensitivity was determined to be 23.3 %. The serum level of CEA antigen was positive in 11 out of 30 lung cancer patients. The mean serum level of CEA antigen markers was higher in patients than in controls; the difference was statistically significant (P< 0.001). The sensitivity of this test was determined to be 36.6 %.
Conclusion: This study showed that the sensitivity of CK19 mRNA in peripheral blood was low, but it had a high specificity for the diagnosis of primary lung cancer. Also, it was found that CEA antigen could be the specific marker for the early detection of lung cancer in patients’ peripheral blood.

Abstract
Background and Aim: Chronic myeloid leukemia (CML) is a myeloprolifrative neoplasm that is characterized by an expansion of myeloid, erythroid cells and platelets in peripheral blood and myeloid hyperplasia in bone marrow. Secreted frizzled-related protein family is a negative regulator of the Wnt signaling pathway that suppresses this signaling pathway in healthy individuals. Aberrant regulation of the Wnt signaling pathway is a prevalent theme in cancer biology, and methylation in promoter of SFRP family has been shown to cause uncontrolled cell proliferation in cancer. Chronic myeloid leukemia was the first malignancy in which the important role of Wnt signaling pathway has been described.
In the present study, we examined the methylation status of SFRP1 and SFRP2 genes in patients with CML.
Materials and Methods: Blood samples were obtained from 25 healthy individuals and 33 patients whit chronic meyloied leukemia (23 male, 10 female) Then Isolated DNA was treated with sodium bisulfite and analyzed by methylation-specific polymerase chain reaction (MSP) with primers specific for methylated and unmethylated promoter sequences of the SFRP1 & -2 genes. We used Mann-Whitney u-tests to investigate the correlation between SFRP-1 and SFRP-2 genes hypermethylation and clinical parameters.
Results: In CML patient hypermethyleation frequency of SFRP-1 and SFRP-2 genes were 16.1℅ and 27.2% respectively. In control group SFRP-1 and SFRP-2 genes were unmethylated.
Conclusion: The present study showed that, methylation of SFRP genes also occurs in CML like other solid tumors. Therefore, the methylation of these genes may play a role in the initiation of malignant disease.

Abstract
Background and Aim: Burned patients experience a high level of anxiety during dress changing. The use of complementary medicine is one of the methods of anxiety management that many studies have conducted about it in recent years. The purpose of this study was to compare the effectiveness of progressive relaxation with abdominal respiration technique on pain anxiety of burn dressing.
Materials and Methods: This study was a randomized clinical trial with a control group. We selected forty-five patients referred to Zare Hospital in Sari through simple sampling and assigned into three groups. The first group received relaxation intervention, the second group received respiratory technique intervention, and no intervention was performed in the control group. Burn Specific Pain Anxiety Scale (BSPAS) was used to measure pain-related anxiety. SPSS software version 20 was used to analyze the data. Descriptive statistics, ANOVA and Tukey’s post hoc test were used for data analysis.
Results: Based on the results, 28% of the participants in the study were single and 72% were married. In terms of age, most of the participants were between 31 and 40 years old. The findings showed that there was no significant difference between the mean pain anxiety levels in the three groups before the intervention. There was a significant difference in the average burn dressing pain anxiety after the intervention between the relaxation group and the control group (P<0.001) and the breathing techniques group and the control group (P<0.000), so that the average burn dressing pain anxiety in the group Relaxation was reduced by 8.60 units as compared to the control group and in the breathing techniques group by 11.60 units as compared to the control group.
Conclusions: The use of relaxation “techniques” and respiratory techniques, which are non-pharmacological methods, are recommended during dress changing in the burned patient. These methods are simple and inexpensive and can reduce the effects of pain anxiety during dress changing.
