Objective To comprehensively evaluate the association between TNF-α gene −308 G/A polymorphism and the risk of prostate cancer. Methods A meta-analysis was performed to analyze the association between −308 G/A polymorphism and the risk of prostate cancer risk. Results A total of 11 case-control studies (4 919 cases and 5 210 controls) were included in this meta-analysis. The result showed no statistically significant differences in all genotype distribution between prostate cancer cases and controls: dominant model (OR=1.11, 95%CI 0.90 to 1.36, P=0.33), recessive model (OR=0.91, 95%CI 0.70 to 1.18, P=0.47), GA versus GG (OR=1.11, 95%CI 0.90 to 1.37, P=0.33), AA versus GG (OR=0.92, 95%CI 0.71 to 1.20, P=0.55), A versus G (OR=1.07, 95%CI 0.91 to 1.26, P=0.39). In the subgroup analysis by ethnicity, no statistically differences were found between prostate cancer cases and controls. Conclusion This results of meta-analysis suggests that TNF-α gene –308G/A polymorphism may not be a risk factor of prostate cancer. Due to the limited quantity of the includied studies, further studies are needed to validate the above conclusion.
Objective To investigate the risk factors for early in-hospital death in patients with acute Stanford type A aortic dissection and emergency surgical treatment. MethodsWe retrospectively analyzed the clinical data of 189 patients with acute Stanford type A aortic dissection who underwent surgery in the First Affiliated Hospital of Xinjiang Medical University between January 2017 and January 2020. There were 160 males and 29 females with an average age of 46.35±9.17 years. All patients underwent surgical treatment within 24 hours. The patients were divided into a survival group (n=160) and a death group (n=29) according to their outcome (survival or death) during hospitalization in our hospital. Perioperative clinical data were analyzed and compared between the two groups. Results The overall in-hospital mortality was 15.34% (29/189). There was a statistical difference between the two groups in white blood cell count, blood glucose, aspartate aminotransferase (AST), bilirubin, creatinine, operative method, operation time, aortic occlusion time, or cardiopulmonary bypass time (P<0.05). Multivariate regression identified white blood cell count [OR=1.142, 95%CI (1.008, 1.293)], bilirubin [OR=0.906, 95%CI (0.833, 0.985)], creatinine [OR=1.009, 95%CI (1.000, 1.017)], cardiopulmonary bypass time [OR=1.013, 95%CI (1.003, 1.024)] as postoperative risk factors for early in-hospital death in the patients undergoing acute Stanford type A aortic dissection surgery (P<0.05). Conclusion Our study demonstrated that white blood cell, bilirubin, creatinine and cardiopulmonary bypass time are independent risk factors for in-hospital death after acute Stanford type A aortic dissection surgery.
