喹诺酮类药物致急性肾衰临床分析

目的分析喹诺酮类药物对肾脏功能的影响。方法对近14年来应用喹诺酮类药物引起急性肾衰（ARF）29例进行分析。结果应用5d以内者ARF的发生率为10．3％，随着应用时间延长，发生率逐渐增高；55岁以下ARF发生率为2．0％，随年龄增大，发生率逐渐增高；非少尿型ARF预后较好，少尿型预后较差。结论年龄越大，疗程越长，ARF发生率越高。

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.     

高分辨率CT对颞部疾病的检查价值

目的：探讨高分辨率CT（HRCT）对颞部疾病的检查价值。方法：对43例颞部疾病患者行常规CT和高分辨率CT（HRCT）检查所获图像对比分析，并讨论HRCT的检查技术和图像后处理。结果：HRCT对病变的显示率及病变引起骨质破坏的程度，病变边缘，轮廓的显示均明显优于常规CT，尤其能清楚显示常规CT难以显示的中耳及内耳的细微结构，结论：高分辨率CT是颞部疾病的首选检查方法，使用高分辨率CT对颞部疾病的检查给临床提供更多，更准确的诊断信息。     

运动疲劳对大鼠十二指肠电活动的影响

本文报道了大鼠十二指肠电活动在运动疲劳前后的数值。结果表明：在运动疲劳后，快波、慢波振幅明显增加，而其频率却减少；Ⅰ相缩短，Ⅱ相延长，Ⅲ相、Ⅳ相及ＩＤＭＥＣ周期无显著变化；并在运动疲劳后９．７±２．４ｍｉｎ内出现不规律的食后型的电活动。这些改变可了解运动疲劳对消化系统的影响。

nm23-H1基因转染对人胆管癌细胞系QBC939体外浸润能力的影响

目的：探讨nm23-H1基因转染对人胆管癌细胞系QBC939体外浸润能力的影响。方法：将含有全长nm23-H1 cDNA的真核表达载体通过脂腩体法转染人胆管癌细胞系。结果：转染成功的QBC939细胞，其nm23-Hl基因的mRNA、蛋白表达明显增加，转染nm23-H1基因的胆管癌细胞体外浸润能力下降，穿越matrigel的细胞数明显低于亲本QBC939细胞，代表浸润能力的IV型胶原酶（MMP-9）分泌量下降。结论：nm23-Hl基因可以抑制胆管癌细胞的体外浸润能力。     

慢性低氧大鼠肺动脉内皮素mRNA的表达及定位

目的：探讨慢性低氧大鼠肺动脉内皮素－1基因表达及分布。方法：采用生物素标记cRNA探针，对Wistar大鼠肺动脉进行原位杂交。结果：低氧1周组及低氧2周组大鼠大部分肺动脉内皮细胞ET－1mRNA表达呈阳性信号，而对照组大鼠仅极少数阳性信号（P＜0．01）；低氧1周组大鼠部分显示强阳性信号。低氧1周组及低氧2周组大鼠部分肺动脉平滑肌细胞呈现ET-1mRNA表达阳性信号，而对照组大鼠则无阳性信号表达（P＜0．01及0．05）。结论：慢性低氧对大鼠肺动脉ET－1分泌的影响是在基因转录水平进行，且主要细胞定位在肺动脉内皮细胞，此外还包括肺动脉平滑肌细胞。     

止痒扑粉治疗尿布皮炎23例

尿布皮炎为婴儿肛门周围及臀部等尿布遮盖部位发生的接触性皮炎，多因尿布更换不及时，使用市售尿不湿等，使局部皮肤处于潮湿或浸润状态；或尿布洗涤不净，残留的尿渍及粪便易被寄生虫分解而产生氨，刺激皮肤；或尿布上的染料、残留的肥皂及橡胶或塑料本身也可成为刺激因子诱发本病。本人用止痒扑粉治疗尿布皮炎23例取得较好疗效，现报道如下：
