大学生生命教育研究

大学生自杀和校园暴力不断发生在被誉为天子之骄子的象牙塔内。对大学生的这种生命意识淡漠现象仅作心理化的理解和处理并不能从根本上解决问题。心理问题只是问题的表象，对生命缺乏应有的尊重，生命意义缺失和生命关怀的缺位是其深层的原因，生命教育势在必行。     

原发性肾上腺皮质癌的诊治分析

目的总结和提高原发性肾上腺皮质癌的诊治水平。方法回顾分析16例肾上腺皮质癌患者的临床资料。根据其临床症状、内分泌功能测定、影像学特点做出诊断，手术治疗并随访。结果16例患者中，内分泌功能紊乱者8例，以库欣征、性征异常、醛固酮增多症为主。超声、CT、MRI测定肿瘤直径为4．8～19．5cm，平均7．8cm。3例有远处转移。行根治性切除术13例，侵及同侧肾脏者做肾和肾上腙切除术2例，肾上腺肿瘤并腔静脉癌栓切除2例，腔静脉部分切除1例。病理结果：Ⅰ其耳2例，Ⅱ期8例，Ⅲ期3例，Ⅳ期3例。随访3-62个月，手术2年以上的11例患者中有6例仍存活，但1例肺转移，1例骨转移；死亡5例，平均存活26个月。结论肾上腺皮质癌患者预后差。影像学检查结合临床症状是早期诊断的关键，根治性手术是惟一有效的治疗方法。     

The modified outside-in suture: vertical repair of the anterior horn of the meniscus after decompression of a large meniscal cyst

This article describes a modified suture technique designed for the vertical repair of the anterior horn of the meniscus after arthroscopic decompression of a large meniscal cyst. This procedure comprises of three steps: first, the meniscus was pierced vertically using a suture hook and a No. 0 PDS suture. Second, both ends of the No. 0 PDS on the femoral and tibial surfaces of the meniscus were pulled to the outside of the joint capsule using a spinal needle preloaded with suture material. Finally, a skin incision was made adjacent to the suture materials, and both ends were tied. We recommend this technique not only for the vertical repair of the anterior horn of the meniscus after decompression of large meniscal cyst, but also to repair a longitudinal tear of the meniscus.

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。     

Application of a pigment measuring device – Mexameter®– for the differential diagnosis of vitiligo and nevus depigmentosus

Background/purpose: Vitiligo and nevus depigmentosus (ND) present similar hypopigmented macules with significantly different prognoses. Although the distinction between the two diseases is important, differential diagnosis relies on medical history and physical examination, which is far from decisive in some cases. The Mexameter^® is an objective skin color-measuring device, and has been reported to provide a reproducible and sensitive means of quantifying small skin color differences. In this study, we investigated the usefulness of a Mexameter^® for discriminating these diseases.
Methods: A selection of 202 hypopigmented skin lesions (182 from vitiligo and 20 from ND) were the objects of this study. Using a Mexameter, MIs were obtained from lesions and symmetrically located control skin. RMIs, ratios of the MIs of lesional skins to control skins, were calculated.
Results: The mean MIs and RMIs were significantly different for vitiligo and ND. The mean RMI of ND lesions was 74±13, which was significantly higher than that of vitiligo lesions (50±24). No ND lesion had an RMI of <50%.
Conclusion: This study shows that the Mexameter^®, an objective pigment-measuring device, can be used to achieve a more accurate diagnosis of hypopigmentary disorders, and that the relative melanin index (RMI), which represents the relative pigment levels, might be a more effective parameter than the melanin index (MI) itself for comparing pigmentation differences.     

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.
