上尿路移行上皮癌術后膀胱和對側上尿路復發(fā)腫瘤的危險因素分析及腫瘤相關蛋白的基礎研究
[Abstract]:Background: the occurrence of bladder and contralateral upper urinary tract tumors after operation of transitional epithelial carcinoma of upper urinary tract is rarely reported. According to the current study, the literature factors of this phenomenon have not been determined. In addition, some case reports describe the characteristics of recurrent tumors and contralateral tumors, as well as the relationship between them. Methods: the original files of 882 cases of transitional epithelial carcinoma in the second affiliated Hospital of Dalian Medical University in recent 10 years were sorted out, the primary bladder tumor and distant metastasis were eliminated, and 11 variables of 112 cases were analyzed by multivariate analysis. To determine the recurrence factors of transitional epithelial carcinoma of upper urinary tract. Results: after operation, the recurrence rate of bladder and contralateral upper urinary tract tumors was 31.2% and 5.8%, respectively. Multiple tumors of upper urinary tract are the risk factors of recurrent bladder cancer after operation, and bladder tumors and renal insufficiency are the risk factors of recurrent tumors of contralateral transitional epithelial carcinoma of upper urinary tract. The recurrence time and stage of recurrent bladder tumor and contralateral upper urinary tract tumor were significantly different from those of contralateral upper urinary tract tumor. Conclusion: it is necessary to perform cystoscopy regularly in patients with primary transitional epithelial carcinoma of upper urinary tract. Patients with recurrent contralateral upper urinary tract tumors are examined by cystoscopy at the same time. Intravenous urography (IVU) or CT urography (CTU). Should be performed Glucokinase 3 尾 (Glycogen synthase kinase3 尾 (GSK3 尾) is a multifunctional serine / threonine kinase involved in many biological processes, especially insulin pathway and Wnt pathway. GSK3 尾 can also be phosphorylated by protein kinase B (protein kinase B. For the nitrogen terminal Arg4 and Arg6 mutation of GSK3 尾 to alanine, the autophosphorylation of Ser9 was significantly weakened. Although such experimental results have been reported earlier, the specific self-inhibition mechanism at the molecular level is not fully understood. In our study, the mutation of Arg4 and Arg6 into alanine significantly weakens the affinity between PKB and GSK3 尾. Compared with the wild type, it is meaningful that the mutation leads to the loss at the atomic level. We analyze the important changes of the mutant complex from four aspects (conformational, residue movement, hydrogen bond and binding free energy). The decrease of affinity of mutants significantly weakened the phosphorylation of GSK3 尾 and the self-inhibition of GSK3 尾. This is of great significance to explain the autoinhibition mechanism of GSK3 尾, and may be applied to the study of the mechanism of type 2 diabetes mellitus and tumor and the development of drugs.
