目的 探讨2型糖尿病肾病(DN)患者肾组织中STOML2的表达及作用。方法 免疫组化检测临床2型糖尿病肾病患者肾组织STOML2的表达及定位,采用慢病毒转染方法建立稳定过表达STOML2的HK-2细胞系,并应用Western blot检测肾小管上皮细胞钙粘蛋白(E-cadherin)、Fibronectin和STOML2的表达。结果 STOML2在DN患者肾组织的肾小管上皮细胞胞浆中表达明显升高。在高糖刺激HK-2细胞建立的EMT模型中,STOML2呈时间依赖表达上调。STOML2稳定高表达时,E-cadherin表达下调,而Fibronectin明显上调,即能促进肾小管上皮细胞发生EMT。结论 STOML2可能通过促进肾小管上皮细胞向间充质细胞分化,进而参与糖尿病肾病肾脏纤维化的发生发展。

Objective To investigate the expression and role of STOML2 in renal tissue of patients with type 2 diabetic nephropathy. Methods To detect he expression and localization of STOML2 in clinical renal tissue in patients with type 2 diabetic nephropathy by immunohistochemistry, and use lentiviral transfection method to establish a stable cell line of over-expressing STOML2, lastly apply western blot to detect the expression of E-cadherin, Fibronectin and STOML2 in renal tubular epithelial cells. Results STOML2 was significantly increased in renal tubular epithelial cytoplasm of patients with DN. In the EMT model of HK-2 cells stimulated by high glucose, STOML2 was increased in a time dependent. Overexpression of STOML2 led to E-cadherin down-regulated, while Fibronectin up-regulated, which promoted the occurrence of EMT in renal tubular epithelial cells. Conclusion STOML2 may be involved in the development and progression of renal fibrosis in diabetic nephropathy by mediating epithelial- mesenchymal transition of renal tubular epithelial cells.

Objective To investigate the effect of anesthesia depth monitoring on the recovery quality and nursing quality of patients treated with lower abdominal surgery under general anesthesia. Methods A total of 120 patients who underwent the lower abdominal surgeries from June 2015 to December 2015 were randomly divided into 2 groups: non-Narcotrend monitoring group (non NT group) and Narcotrend monitoring group (NT group). And each group contains 60 cases. All patients were set in the same induce plan, and maintained by propofol-fentanyl during the operation. The dosage of propofol, the time of tracheal extubation, the PACU staying time, the Ricker sedation-agitation scale, the incidence of PONV and POD, the nursing quality and nursing working load were recorded in the project. Results Using Narcotrend to monitor the anesthesia depth could significantly decrease the dosage of propofol (P<0.05). The tracheal extubation time and the PACU staying time of patients in NT group were much shortened than patients in non NT group (P<0.05). In NT group the Ricker scores of patients were much lower than patients in non NT group (P<0.05). And the effective anesthesia depth monitoring using Narcotrend could significantly decrease the nursing working load and improve the nursing quality (P<0.05). Conclusion Effective anesthesia depth monitoring using Narcotrend may improve the recovery quality in the PACU, which may decrease the working load of nurses and improve the nursing quality in PACU.
