循证护理在临床实习教学中的尝试

循证护理（evidence based nursing，EBN），直译为“以证据为基础的护理”，指护理人员在护理实践中将科研结论与病人需求相结合，考虑当时护理环境，结合个人经验，最终做出护理决策，其核心内容是运用现有最好的科学证据为服务对象提供服务。循证护理是20世纪90年代随着循证医学的发展而发展起来的，是一种新概念，新观点，新思维。经调整发现我市实习护生对循证护理了解甚少。

前列腺癌的诊断和治疗进展前列腺癌的早期诊断

一、概况 在欧美国家,前列腺癌(Pca)是50岁以上男子最常见的恶性肿瘤,也是男性癌肿死亡的第二位原因(仅次于肺癌).因此,应重视Pca的筛查和早期诊断.尽管我国目前Pca发生率远低于欧美国家,但由于对本病的重视程度和防治力度不够,大多数患者出现症状而就诊时已为较晚期,失去了根治手术的机会,5年和10年生存率低,而医疗费用却上升较快.     

镍铬合金烤瓷修复体394件中远期修复效果回顾性分析

目的:了解镍铬合金烤瓷修复体的中远期修复效果。方法:对我科1995年7月～2005年3月具有完整病历记载并能正常复诊的312例(394件)镍铬合金烤瓷修复体的临床资料进行了回顾性分析。结果:镍铬合金烤瓷修复体3年以上成功率为96.2%,5年以上成功率为92.9%,牙龈炎症、松动脱落、瓷崩是镍铬合金烤瓷修复体失败的3种主要表现。结论:为确保镍铬合金烤瓷修复体的中远期疗效,应从适应证的选择、固位体的设计、基牙制备、烤瓷工艺等方面严格把关。     

真空微波工艺条件对香脆鳙鱼片品质的影响

研究了预脱水鱼片含水量、微波功率、真空度对真空微波加工香脆鳙鱼片品质的影响,在此基础上,采用混合正交试验进一步优化了真空微波制备香脆鳙鱼片的工艺条件。研究结果表明,适宜的水分含量和微波功率可以提高鱼片的膨化率和脆度,改善鱼片的感官品质。高真空度可以改善鱼片的膨化作用和脆性,提高微波加热的效率,很大程度上避免了鱼片出现焦黑点。最佳的真空微波加热条件是预脱水鱼片水分质量分数控制在(15.3±1)%(50℃鼓风干燥3.5 h),微波功率设定为高火档(686±3.5)W,在真空度0.095 MPa下加热12 s后,间歇摇匀后再加热10 s。     

Efficacy and safety of herbal medicines for idiopathic Parkinson's disease: a systematic review.

The objective of this study is to assess the efficacy and safety of herbal medicines (HMs), as a monotherapy or adjunct therapy, compared to placebo or conventional approaches in the treatment of idiopathic Parkinson's disease (PD). We conducted a systematic review of randomized controlled trials from both conventional and alternative medicine sources. Outcome measures were overall improvement, quality of life, reduction of levodopa dose, and adverse events. Nine studies were included, each testing a different HM. Six of the trials had limited internal validity due to major flaws in design, including the lack of proper randomization; insufficient blinding; unclear inclusive criteria in terms of diagnostic criteria, baseline staging, and duration of disease; lack of proper sample size calculation; and insufficient data analysis. Imbalances in gender and ethnicity among the patients in the included trials were observed. No major adverse events emerged, and no specific pattern was detected from the trials describing such data. In addition to major methodological defects, heterogeneity in (1) HM tested, (2) control treatment, and (3) outcome measure hindered in-depth data analysis and synthesis. Current evidence is insufficient to evaluate the efficacy and safety of various HMs. Further studies with improved trial design and reporting, with assessment on cost-effectiveness, quality of life, and qualitative data are warranted.     

间断纵行缝扎硬化注射治疗直肠黏膜内脱垂68例临床分析

目的:观察和评价间断纵行缝扎硬化注射治疗直肠黏膜内脱垂的临床疗效。方法:将68例直肠黏膜内脱垂患者随机分成两组,治疗组(36例)采用经间断纵行缝扎硬化注射治疗,对照组(32例)采用单纯硬化注射治疗。并对临床资料进行分析总结。结果:术后3个月随访,治疗组与对照组的症状、体征总得分比较,治疗组均优于对照组。结论:纵行缝扎硬化注射治疗后症状消除快,近远期疗效佳。     

二甲双胍对多囊卵巢综合征患者胰岛素样生长因子-1的影响

目的探讨二甲双胍对多囊卵巢综合征（PCOS）患者血清胰岛素样生长因子-1（IGF-1）及胰岛素样生长因子结合蛋白-1（IGFBP-1）水平的影响及其作用机制，明确二甲双胍治疗的临床效果。方法2002年1—11月对山西医科大学第二医院24例PCOS患者给予二甲双胍500mg，一日3次，8～24周治疗，比较治疗前后血清IGF-1、IGFBP-1、空腹胰岛素及睾酮水平，并对月经恢复、排卵、妊娠情况进行分析。结果二甲双胍可降低血清空腹胰岛素及睾酮水平，能显著升高IGFBP-1水平，治疗前后血清IGF—1水平差异无显著性。单纯二甲双胍治疗后月经恢复率为41．67％（10／24）；自然排卵率为25．00％（6／24），自然妊娠率为12．50％（3／24）。二甲双胍加促排卵治疗共18个周期，排卵周期率66．67％（12／18），妊娠周期率为11．11％（2／18）。结论二甲双胍可以降低血清空腹胰岛素及睾酮水平，增高IGFBP-1水平，可以改善卵泡微环境，有助于月经恢复，提高促排卵和妊娠率．是治疗PCOS的重要手段。

Breastfeeding by Aboriginal mothers in Perth

Objective: To document the breastfeeding practices of Aboriginal mothers delivering in Perth. Design and methods: A cohort of mothers was followed from the time of delivery for six months to obtain details of infant feeding practices. Subjects: A total of 455 mothers delivered during the study period and were asked to participate. A total of 425 mothers completed the initial questionnaire. Setting: The study was undertaken in six public hospitals in Perth, Western Australia. Data analyses: The data were analysed using spss . Breastfeeding duration was calculated using Kaplan–Meier survival analysis. Main outcome measures: Breastfeeding initiation and duration. Results: The mean age of the Aboriginal mothers was 21.8 years (range 14–39 years, SD 5.32) and the average gestational age was 38.3 weeks. Almost 50% of the mothers in the study delivered by Caesarean section. At discharge from hospital 89.4% (CI 86.6–92.1) of mothers were breastfeeding, declining to 58.8% (CI 53.5–64.1) at six months. When compared with non‐Aboriginal mothers, the Aboriginal breastfeeding rates were higher than the non‐Aboriginal average breastfeeding rates, but lower than the highest socioeconomic group. Conclusions: The breastfeeding rates of Aboriginal mothers are higher than for other Australians. This is despite the low maternal age and level of education and the high rates of low‐birth‐weight infants and Caesarean section among this population. The World Health Organization recommendation for infant feeding is exclusive breastfeeding until six months, but less than one‐third of Aboriginal mothers achieved this recommendation.
