前臂逆行骨间背侧皮瓣的临床应用

目的总结前臂逆行骨间背侧皮瓣的临床疗效。方法回顾性分析42例前臂逆行骨间背侧皮瓣，并结合文献阐明其变异程度及变异的处理。结果骨间背侧血管在前臂中1／3缺如1例．皮瓣边缘坏死；皮瓣向近端延伸超过4cm者4例，远端坏死，延迟愈合；其余均一期愈合：结论虽然前臂骨间背侧血管有变异，但前臂逆行骨间背侧皮瓣仍是修复手背中等大小创面较为理想的方法，以近点皮肤穿支向近端延伸皮瓣不要超过4cm。

无抽搐电痉挛治疗精神分裂症的疗效观察分析

目的观察无抽搐电痉挛（Modified Electrocnvulsive therapy，MECT）治疗精神分裂症的疗效及给予次数的关系。方法将60例诊断为精神分裂症的住院患者按治疗次数随机分为两组，进行MECT的临床资料总结分析。结果治疗次数≥6次组，显效率为83．3％，次数〈6次组显效率为76．7％，两者显效率无显著性差异（P〉0．05），每组治疗前后BPRS评分有显著差异，但两组间比较无显著差异（P〉0．05），未发现严重不良反应。结论MECF安全性高，有一定疗效，与治疗次数关系不大。     

Hand hygiene and glove use behavior in an Italian hospital.

In an Italian hospital, we observed that hand hygiene was performed in 638 (19.6%) of 3,253 opportunities, whereas gloves were worn in 538 (44.2%) 1,218 of opportunities. We observed an inverse correlation between the intensity of care and the rate of hand hygiene compliance (R2=0.057; P<.001), but no such association was observed for the rate of glove use compliance (R2=0.014; P=.078). Rates of compliance with hand hygiene and glove use recommendations follow different behavioral patterns.     

人胎儿前庭器超微结构的观察

对人胎儿前庭器超微结构的研究,国内外报道甚少。本文对18至36周人胎儿颞骨10具进行了扫描电镜和透射电镜的观察,并对应用Surface preparation法制做人胎儿前庭器标本的方法进行了探讨。本文观察所见:豚鼠平衡斑的生理状态与人胎儿很近似,体面积比人胎儿平衡斑小,感觉毛长,细胞排列更整齐。28周以后的胎儿因前庭周围骨质变硬,制做标本时可以分别取出两囊斑和壶腹嵴。     

重症肌无力患者泼尼松治疗前后免疫学指标的变化

探讨泼尼松治疗重症肌无力（MG）免疫学机制。对382例MG患者在漏尼松中剂量冲击，小剂量维持疗法治疗前后，检测酰胆碱受体抗炎（AchRab)，突触前膜抗体（PsMab)，单个核细胞亚群（PBMC），肿瘤坏死因子（TNF），可溶性白介素－2受体（SIL－2R），β2－微球蛋白（β2－m)，以及红细胞免疫功能的变化。结果表明：MG患者在泼尼松治疗前后多项免疫指标有显著性的变化。为泼尼松治疗MG提供了评定疗效的免疫学指标，进一步阐明了MG发病的免疫学机制。     

Objective responses in patients with malignant melanoma or renal cell cancer in early clinical studies do not predict regulatory approval.

PURPOSE: Tumor responses in early-phase trials are used to determine whether new agents warrant further study. Given that spontaneous regressions are observed in melanoma and renal cell carcinoma, this study assessed whether tumor responses, particularly in these two tumor types, predict for future regulatory drug approval. EXPERIMENTAL DESIGN: The literature was reviewed to assess tumor response rates to cytotoxic agents in phase I and II trials in the following solid tumors: melanoma, renal cell carcinoma, non-small-cell lung cancer, breast cancer, ovarian cancer, colorectal cancer, and other solid tumors. Response rates were categorized and the relationship of these categories to the end point of regulatory drug approval was determined. RESULTS: Fifty-eight drugs were assessed in 100 phase I trials, and 46 of these drugs were also studied in 499 phase II trials. Higher overall response rates in both phase I trials (P = 0.03) and phase II trials (P < 0.0001) were predictive of regulatory approval. However, response in melanoma or renal cell carcinoma was not predictive for either phase I or phase II studies. CONCLUSIONS: For cytotoxic agents, although overall objective response rates reliably predict subsequent marketing approval, isolated responses in melanoma and renal cell carcinoma are not predictive.

A novel DRB1*09 allelic sequence in the Jing ethnic minority of China.

A new DRB1 allele, DRB1*0902, has been identified in an individual of the Jing ethnic minority. Its sequence was confirmed by sequencing of PCR products and clones. This allele differed by three nucleotides from DRB1*09012 at positions 157, 161 and 166, and resulted in amino acid motif substitution from VAES to DAEY.
