OBJECTIVE@#To investigate the expression and correlation of miR-211, miR-155, and C-myc in acute T lymphocytic leukemia (T-ALL), aiming to provide evidence for the diagnosis and treatment.@*METHODS@#A total of 96 T-ALL patients who were diagnosed and treated in People's Hospital of Zhengzhou from June 2014 to June 2017 were selected, and 69 healthy volunteers who had a physical examination were selected as control group in the same period. Real-time fluorescent quantitative PCR (RT-PCR) was used to determine the expression levels of miR-211, miR-155, and C-myc in peripheral blood mononuclear cells in each group. Kaplan-Meier was used to analyze the survival of T-ALL patients and correlation of miR-211, miR-155, and C-myc with prognosis. Pearson correlation analysis was used to evaluate the correlation of miR-211, miR-155, and C-myc with disease risk.@*RESULTS@#The expression levels of miR-211 mRNA, miR-155 mRNA, and C-myc mRNA in T-ALL group were higher than those in the control group (P<0.01), those in non-remission group were higher than those in remission group (P<0.01), and those in high-risk group were also higher than those in low-risk group and intermediate-risk group (P<0.01). The survival time of T-ALL patients with low miR-211 expression was longer than that with high miR-211 expression (P<0.01), that with low miR-155 expression was longer than that with high miR-155 expression (P<0.01), and that with low C-myc expression was also longer than that with high C-myc expression (P<0.01). The high expression of miR-211, miR-155, and C-myc was linearly positively correlated with high risk of disease (r=0.749, 0.781, 0.804).@*CONCLUSION@#The expressions of miR-211, miR-155, and C-myc are up-regulated in T-ALL patients, closely related to prognosis, and linearly positively correlated with disease risk.

(2) AC genotype might interact with excessive salt consumption (hypertension group, 31/220, 15.5%; control group 10/220, 4.5%, OR: 4.67, 95%CI: 2.15 - 10.15), overweight (hypertension group, 19/220, 8.6%; control group, 9/220, 4.1%, OR: 6.96, 95%CI: 2.33 - 20.76) and drinking large volume of salty milk (hypertension group, 20/220, 9.1%; control group, 10/220, 4.5%, OR: 2.67, 95%CI: 1.11 - 6.42) which will raise hypertension hazard of AC genotype.</p><p><b>CONCLUSION</b>There is no relationship between the A1166C gene polymorphism of AT(1R) gene and hypertension of Kazakh people. AC genotypes might also interact with food consumption habit and behavior factors and increase the individual risk of hypertension.</p>

A case-control study on risk factor of Kaposi's sarcoma in Xinjiang / 中华流行病学杂志

<p><b>OBJECTIVE</b>To analyse related risk factors of classic Kaposi' s sarcoma in Xinjiang.</p><p><b>METHODS</b>A 1:4 case-control study was used and the conditional logistic regression model was performed in this study. Cases were followed up in Xinjiang while controls were selected by the same sex, nation and age within 5 years with cases.</p><p><b>RESULTS</b>Interleukin-6,vascular endothelial growth factor, beta-MG, neopterin, human herpevirus 8, were found to be associated with Kaposi's sarcoma risk in one-way variance model while beta2 -MG and human herpevirus 8 entered the multiple conditional logistic regression model, and their ORs were 1.002(95%CI: 1.000-1.003), 81.041 (95%CI: 1.790-3669.620).</p><p><b>CONCLUSION</b>There was a correlate relationship between beta2 -MG and classic Kaposi's sarcoma being found that human herpevirus 8 exposure related factors seemed to have played important roles on classic Kaposi's sarcoma in Xinjiang.</p>
