大学生社会适应性现状调查

目的:研究在校大学生的社会适应性现状。方法:采用大学生社会适应性问卷对大学生进行调查。结果:1大学生的社会适应性在自我调节、自我评价、就业准备、人际交往和角色适应等维度上存在显著的性别差异(t=-3.996,3.614;P0.001;t=3.016,P0.01;t=6.843,3.639;P0.001),在学习管理维度上性别差异不显著;2大学生的社会适应性在自我调节、学习管理、就业准备和角色适应等维度上存在显著的毕业班与非毕业班差异(t=-3.626,4.040;P0.001;t=2.954,P0.01;t=4.056,P0.001),在自我评价和人际交往等维度上毕业班与非毕业班差异不显著。结论:高校应当采取切实措施,把社会适应能力培养列入人才培养方案,构建科学的社会适应能力培养的课程体系,改革社会适应能力培养课程的内容和方法,创设模拟情境训练大学生的社会适应能力。     

无痛分娩与剖宫产的临床探讨

目的:探讨硬膜外腔麻醉无痛分娩对母婴的影响,以有效控制剖宫产率.方法:选择我院2008-2010年间无硬膜外腔麻醉无痛分娩禁忌证、经产房待产的初产妇120例实施无痛分娩,并与自然分娩的初产妇120例对照研究.结果:120例无痛分娩初产妇镇痛效果好,据WHO疼痛分级标准,效果均达到Ⅰ级以上,剖宫产率低,比对照组低32个百分点.但镇痛组静脉滴注催产素率明显高于对照组,其他差异无统计学意义.结论:硬膜外腔麻醉无痛分娩可减轻初产妇的生产痛苦,操作性强,安全性较高,剖宫产率低,值得在临床推广.     

微波治疗在糖尿病患者腹部术后切口愈合中的应用及护理

目的探讨微波治疗在糖尿病患者腹部术后切口愈合中的应用效果。方法选择2009年10月～2010年10月本院外科行腹部手术的2型糖尿病患者100例,随机分为实验组和对照组,每组各50例。对照组采用常规护理,实验组在此基础上增加微波照射治疗,比较两组患者术后切口愈合情况及各项临床指标的差异。结果两组患者切口愈合情况及愈合时间比较,均P<0.05,差异具有统计学意义,实验组切口愈合情况优于对照组,切口愈合时间短于对照组。结论糖尿病患者腹部手术后切口应用微波照射治疗,可促进切口愈合,提高愈合效果,减轻患者痛苦,从而缩短围手术期时间,促进患者康复。     

The efficacy and safety of the fractional radiofrequency technique for the treatment of atrophic acne scar in Asians: A meta-analysis

Background: The fractional radiofrequency (fRF) technique is a recently emerged technique. However, the exact outcomes of fRF for treating atrophic acne scar in Asians are still unclear. Objective: To compare the clinical outcomes of fRF with the fractional laser technique in Asians with atrophic acne scar. Materials and methods: The databases MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials, and Chinese National Knowledge Infrastructure (CNKI) were searched. Main clinical outcomes were participant-reported scar improvement, investigator-reported scar improvement, post-inflammatory hyperpigmentation (PIH), erythema duration, scab duration, and the pain level. Result: Six randomized controlled trials were included in this meta-analysis. The scar improvement was similar in both groups regarding participant-reported scar improvement (p = 0.48) and investigator-reported scar improvement (p = 0.89). However, the incidence of PIH in fRF group was lower in comparison with the laser group (p < 0.001). The average duration of erythema was shorter in fRF group than in the laser group (p < 0.001). The mean time for debridement was shorter in fRF group than the carbon dioxide fractional laser system (p = 0.02). The pain level did not differ significantly in the two groups (p = 0.53). Conclusion: Although some bias exists in our study, fRF appears to be a superior alternative for the treatment of atrophic acne scar in Asians.     

Serum levels of MMP-11 correlate with clinical outcome in Chinese patients with advanced gastric adenocarcinoma

Background  

The aim of the present study was to investigate the association between serum levels of matrix metalloproteinase 11 (MMP-11) and responses to front-line chemotherapy and prognosis in advanced unresectable gastric adenocarcinoma.
