目的:腎功能不全在急性冠脈綜合癥及其它心血管疾病中通常伴隨著較高的死亡率。而血漿尿素氮是反映血液動力學改變及腎臟灌注改變的非常敏感的指標。本試驗研究血漿尿素氮水平的高低對于急性ST段抬高型心肌梗塞患者死亡率的預測作用。方法:研究300名患急性ST段抬高型心肌梗塞患者長程的死亡率與入院時血漿尿素氮水平及住院時血漿尿素氮水平升高之間的關系。結果:在平均隨訪27個月,56(185%)個患者死亡。使用生存分析對于血漿尿素氮水平升高與血漿尿素氮水平正常兩組患者進行研究,用log-rank檢驗將兩組數據進行比較,有明顯統計學意義,Plt;0.001。結論:對于患急性ST段抬高型心肌梗塞患者的長期死亡率,入院時的血漿尿素氮水平是一個獨立的預測因素。BUN和BUN/creatinine比值的增高也能對患急性ST段抬高型心肌梗塞患者的長期死亡率提供一定的預測信息。同時,住院期間的BUN增高對于患急性ST段抬高型心肌梗塞患者的長期死亡率也能夠提供額外的預測信息。
OBJECTIVE To introduce the method using the gracilis myocutaneous flaps to repair of vulvar defect after radical vulvectomy. METHODS The gracilis myocutaneous flaps were applied in 4 cases with vulvar carcinoma which located vestibule of vulva and bulk, and the carcinoma was large after radical resection to repair vulvar defect simultaneously. RESULTS The incision of 3 cases was healing by first intention, and 1 case with type II diabetes mellitus was healing by second intention. After followed up 3-6 years, 1 case was recurrent in 2 years after operation, 3 cases were survival without complication. CONCLUSION Vulvar reconstruction with the use of gracilis myocutaneous flaps in radical vulvectomy could markedly decrease the rate of complication.
ObjectiveTo explore the role of interleukin-6 (IL-6) in cervical cancer cell C-33A.MethodsThe cervical cancer cells C-33A were divided into the IL-6 group and the control group after culture. The IL-6 group were treated with 50 ng/mL of recombinant IL-6 protein, and the control group were without IL-6. Then cell viability and cell migration were detected by MTT assay and wound-healing assay, respectively. The mRNA and protein expressions of epithelial-cadherin (E-Cad), neural-cadherin (N-Cad), vimentin and transcription factors-snail1 (TFs-SNAIL1) were analyzed by real time quantitative polymerase chain reaction and Western blotting, respectively.ResultsCompared with the control group, in the IL-6 group the proliferation of cervical cancer cells C-33A was promoted (12 h: 0.388±0.025 vs. 0.597±0.057; 24 h: 0.547±0.021 vs. 0.798±0.036; 48 h: 0.745±0.056 vs. 1.296±0.122; 72 h: 1.074±0.053 vs. 1.805±0.113; P<0.05), and the relative migration ability of cervical cancer cell was promoted (12 h: 1.057±0.029vs. 1.200±0.045; 24 h: 1.189±0.036 vs. 1.428±0.181; 48 h: 1.273±0.059 vs. 1.569±0.143; 72 h: 1.409±0.047 vs. 1.623±0.170; P<0.05); meanwhile, compared with the control group, in the IL-6 group, the expression of E-Cad mRNA (1.012±0.098vs. 0.483±0.171, P<0.01) and E-Cad protein (1.032±0.015vs. 0.395±0.119; P<0.01) decreased, the expression of N-Cad mRNA (1.054±0.106vs. 1.465±0.230, P<0.01) and N-Cad protein (1.040±0.043vs. 1.605±0.128, P<0.01) increased, the expression of vimentin mRNA (1.050±0.083vs. 1.340±0.099, P<0.05) and vimentin protein (1.043±0.062vs. 1.430±0.077, P<0.05) increased, and the expression of TFs-SNAIL1 mRNA (1.058±0.176vs. 1.510±0.229, P<0.01) and Fs-SNAIL1 protein (1.022±0.015vs. 1.470±0.139, P<0.01) increased.ConclusionIL-6 may promote the proliferation, migration, and epithelial-mesenchymal transition of cervical cancer cell C-33A.
