Objective We aimed to describe the prevalence of metabolic syndrome, its epidemiological characteristics, and to analyse the relationship of waist-to-hip ratio (WHR) and body mass index (BMI) with metabolic syndrome (MS) among staff at Southeast University. Methods The data from the overall physical examination of 1979 staff were analyzed.Results The crude prevalence of MS were 21.7%,26.4% and 14.2% in the whole population, men and women respectively. The standardized rates were 14.7%,19.0% and 9.4%. The prevalence of MS in men was significantly higher than that in women(Plt;0.05). Both abdominal obesity and visceral obesity were positively correlated with the prevalence of MS(r=0.295, 0.248, P=0.000). Conclusion The prevalence of MS among staff of Southeast University has shown a significant increase in 2006. WHR and BMI are both correlated with the prevalence of MS.
Mesenchymal stem cells (MSC) are considered to have important value in the treatment of various diseases because of their low immunogenicity, transferability, and strong tissue repair capacity. Stromal cell derived factor-1 (SDF-1) and its receptor CXC chemokine receptor 4 (CXCR4) pathway plays an important role in migration of MSC. The induction of homing of MSC to retina by regulating SDF-1/CXCR4 may exert the curative effect on diabetic retinopathy to greatest exent.
目的 总结我院35岁以下青年人胃癌43例的诊治经验。方法 对43例患者临床特征、诊断及治疗进行回顾性分析。结果 手术40例，根治性切除14例，姑息性切除9例，胃空肠吻合6例，单纯探查11例，切除率57.50%。术后3个月内死亡5例，4～12个月内死亡18例，12～24个月内死亡8例，生存2年以上9例，5年以上3例。误诊26例，误诊率60.46%。结论 青年人胃癌发病率低，恶性程度高，病程短，转移早，早期诊断率低，误诊率高，治疗关键是提高早期诊断率。
Objective To systematically assess the effectiveness and safety of streamlined liner of the pharynx airway (SLIPA) compared with endotracheal tube (TT) for airway management in patients undergoing laparoscopic cholecystectomy surgery. Methods Databases such as PubMed (1992 to February 2012), EMbase (1984 to February 2012), MEDLINE (Ovid, 1964 to February 2012), SCI (1992 to February 2012), CNKI (1992 to February 2012), CBM (2002 to 2012) as well as WanFang Data (1992 to February 2012) were searched for relevant literature. The references of the included articles were also manually traced. Two reviewers independently screened the trials according to inclusion and exclusion criteria, extracted the data, and assessed the quality of methodology. Meta-analyses were performed using RevMan 5.0 software. Results Ten randomized controlled trials (RCTs) involving 664 patients were included. Results of meta-analysis showed that: a) as for side effects, none of the patients experienced regurgitation or hypoventilation during operation; b) as for extubation response, SLIPA was proved fewer than TT during extubation with a significant difference (RR=0.14, 95%CI 0.05 to 0.36, Plt;0.000 1); c) SLIPA was superior to TT with regard to reducing postoperative sore throat (RR=0.15, 95%CI 0.06 to 0.38, Plt;0.000 1); d) SLIPA was similar to TT with regard to Ppeak after peritoneal insufflations (WMD=–0.07, 95%CI –0.73 to 0.59, P=0.83); e) as for PETCO2, the SLIPA group was lower than the TT group obviously after peritoneal insufflations (WMD=–1.09, 95%CI –1.70 to –0.49, P=0.000 4); f) as for hemodynamic change, the SLIPA group was more stable than the TT group during the operation with significant differences (Plt;0.05). Conclusion Current studies suggest that it is safe and effective to apply SLIPA for ventilation in laparoscopic cholecystectomy surgery. However, due to the limited quantity and quality of the included studies, more high-quality studies are need.
