目的:肾功能不全在急性冠脉综合症及其它心血管疾病中通常伴随着较高的死亡率。而血浆尿素氮是反映血液动力学改变及肾脏灌注改变的非常敏感的指标。本试验研究血浆尿素氮水平的高低对于急性ST段抬高型心肌梗塞患者死亡率的预测作用。方法:研究300名患急性ST段抬高型心肌梗塞患者长程的死亡率与入院时血浆尿素氮水平及住院时血浆尿素氮水平升高之间的关系。结果:在平均随访27个月,56(185%)个患者死亡。使用生存分析对于血浆尿素氮水平升高与血浆尿素氮水平正常两组患者进行研究,用log-rank检验将两组数据进行比较,有明显统计学意义,Plt;0.001。结论:对于患急性ST段抬高型心肌梗塞患者的长期死亡率,入院时的血浆尿素氮水平是一个独立的预测因素。BUN和BUN/creatinine比值的增高也能对患急性ST段抬高型心肌梗塞患者的长期死亡率提供一定的预测信息。同时,住院期间的BUN增高对于患急性ST段抬高型心肌梗塞患者的长期死亡率也能够提供额外的预测信息。
Day surgery is regarded as a breakthrough in promoting the construction of hierarchical diagnosis and treatment because of its advantages such as effectively shortening the length of hospital stay and making full use of medical resources. In order to comply with the national policies, medical development, patient needs, and other factors, as a comprehensive tertiary hospital, Zhengzhou Central Hospital Affiliated to Zhengzhou University taking regional synergy as a carrier, combining with 92 medical units, actively explores the rational flow of patients with day surgery in the region, through implementing clinical path management, controlling surgery expenses and drug and consumables proportions, purchasing medical health insurance for day surgery patients to ensure patient safety, opening a green channel for patients at the grassroots level, effectively using the medical insurance to co-ordinate funds, and rationally planning medical treatment procedures, ect.
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.
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 systematically review the effect of thalidomide as first-line therapy on postrelapse survival rate of patients with multiple myeloma (MM). MethodsDatabases including PubMed, EMbase, The Cochrane Library (Issue 1, 2007) and Web of Science were searched to collect randomized controlled trials (RCTs) about thalidomide as first-line therapy for MM from 2006 to 2011. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies. Then, meta-analysis was performed by using RevMan 5.1 software. ResultsA total of 16 RCTs involving 6097 patients were included. The results of meta-analysis showed that, compared with the chemotherapy alone group, early application of thalidomide could significantly decrease the postrelapse survival rate (HR=1.23, 95%CI 1.05 to 1.45, P=0.002). Subgroup analysis showed that, compared with the chemotherapy alone group, thalidomide maintenance therapy after autologous stem cell transplantation (ASCT) couldn’t decrease the postrelapse survival rate (HR=0.90, 95%CI 0.57 to 1.41, P=0.64), but thalidomide induction therapy before ASCT (HR=1.21, 95%CI 1.01 to 1.45, P=0.04) and thalidomide induction therapy before ASCT combined maintenance therapy after ASCT (HR=1.41, 95%CI 1.13 to1.76, P=0.002) could significantly decrease the postrelapse survival rate. ConclusionCurrent evidence shows that, thalidomide maintenance therapy after ASCT for MM is a better therapy regimen. It couldn’t decrease the survival rate after recurrence, but could increase the disease-free survival (DFS) and overall survival (OS) of patients with MM. Due to the limited quality of included studies, the above conclusion still needs to be verified by more high quality studies.
