  • Twist与E-cadherin在结直肠癌中的表达及其意义

    目的探讨Twist和E-cadherin蛋白在结直肠癌组织中的表达及其可能的机理、相互作用以及与结直肠癌预后的关系。 方法应用免疫组化SP法检测63例结直肠癌组织以及21例正常结肠黏膜组织中Twist和E-cadherin蛋白的表达,并分析其与结直肠癌临床病理特征和患者预后的关系。 结果Twist蛋白在结直肠癌组织中的表达阳性率为66.7%(42/63),而在正常结直肠黏膜组织中的表达阳性率为14.2%(3/21),前者高于后者(P<0.01);E-cadherin蛋白在结直肠癌组织中的表达阳性率为20.6%(13/63),而在正常结直肠黏膜组织中的表达阳性率为81.0%(17/21),前者低于后者(P<0.01)。两者的表达与肿瘤的分化程度及T、N和M分期均相关(P<0.05)。相关性分析显示,Twist和E-cadherin蛋白的表达呈负相关关系(r=-0.215,P=0.039)。 结论Twist和E-cadherin蛋白的表达可能与结直肠癌的发生发展和侵袭转移相关,并可作为评价结直肠癌生物学行为和预后的重要指标。Twist和E-cadherin蛋白表达呈负相关关系提示,在上皮-间质转化过程中可能是通过抑制E-cadherin蛋白的表达来实现的。

  • Study on the expression of Cdc42、N-WASP、Arp2/3 in peripheral blood of patients with drug-resistant epilepsy

    ObjectTo investigate the pathogenesis of drug-resistant epilepsy by examining the expression of mRNA and protein of Cell Division Cycle 42 GTP-binding protein (Cdc42), Neural Wiskott-Aldrich Syndrome Protein (N-WASP) and Actin-related protein 2/3(Arp2/3) in peripheral blood of patients with drug-resistant epilepsy (DRE).MethodsSeventy two essential epilepsy patients who were attended at outpatients and inpatients in the Department of Neurology of the Affiliated Hospital of Youjiang Medical University for Nationalities were selected from October 2016 to October 2018. According to the 2010 International League Against Epilepsy’s definition of Drug-Resistant Epilepsy, the patients were divided into 2 groups: 32 patients with DRE were defined as DRE group, 40 patients with anti-epilepsy drugs (AEDs) well controlled were defined as the well controlled group. Thirty two healthy persons were selected as control group. The expression of mRNA and protein of Cdc42, N-WASP and Arp2/3 in peripheral blood were measured by quantitative real-time PCR (RT-qPCR) and Western blot(WB). Experimental data were analyzed by ANOVA or rank-sum test.ResultsCompared with well-controlled group and healthy persons group, Cdc42, N-WASP, Arp2/3 in DRE group were significantly increased, the differences were statistically significant (P<0.05). Compared with the control group, Cdc42, N-WASP, Arp2/3 in well-controlled group were significantly increased, with statistically significant differences (P<0.05).ConclusionThe expression of Cdc42, N-WASP, Arp2/3 in peripheral blood of patients with DRE significantly increased, being closely related to the occurrence and development of DRE, and used as indicators in peripheral blood predicting the occurrence of DRE.
