改良开放性手术治疗巨大良性前列腺增生症

目的探讨巨大良性前列腺增生症的开放性手术治疗方法及效果。方法回顾分析16例巨大良性前列腺增生症,年龄61~88岁,平均74岁。作耻骨上经膀胱前列腺切除术。结果手术均成功;手术时间35~65min,出血量100~200mL,术后前列腺重量为200~520g,平均215g;膀胱冲洗2~3d,拔导尿管5~7d;术后3d再出血1例,经DSA同侧髂内血管栓塞止血成功,排尿困难1例,短期尿失禁1例,其余患者术后均排尿通畅,控尿良好。结论开放性手术治疗巨大良性前列腺增生症,其梗阻解除彻底,是一种合理的治疗方法。恰当的手术方法是提高疗效及降低并发症的关键。     

大鼠腹腔肥大细胞肿瘤坏死因子合成与释放的研究

应用免疫细胞化学技术及酶联免疫吸附试验（ELISA）对大鼠腹腔肥大细胞合成和释放肿瘤坏死因子（TNF）的状况进行了观测。结果:新鲜分离纯化的大鼠腹腔肥大细胞胞浆呈TNF蛋白阳性。单纯肥大细胞培养早期（2～4 h）,上清液中未能检测到TNF,随着培养时间延长,上清液中TNF含量增多;盐酸吗啡与肥大细胞共同培养2h时,上清液中出现可测TNF。四甲基偶氮唑盐（MTT）比色分析试验表明,肥大细胞培养上清液具体有TNF的抗肿瘤活性中。提示:大鼠腹腔肥大细胞能合成和释放TNF,盐酸吗啡能促进肥大细胞释放TNF。     

Lesbianism in China

Lesbianism in China has a long but usually hidden history. This paper examines the historical and literary sources of the past to illustrate the history of lesbianism and then turns to a survey of lesbianism in the China of today. As in the past, lesbianism remains more or less hidden, and comes to light only occasionally. Data for contemporary China comes from a visit to an institution for delinquent young women, recent police records, and contemporary fiction. It has only been in the past 4 or 5 years that it was possible to talk about lesbianism and most lesbians are fearful of becoming identified.     

高护生临床授课效果评价

高等护理毕业生应具备临床护理、护理教育、护理科研、护理管理、社区护理5方面的能力。其授课水平的高低将成为评价高护生护理教育能力的重要指标。我院从2002年起探讨对高护生临床授课的教学模式，以提高授课水平。笔者对2004年-2005年在我院实习的168名高护生进行调查，现将结果报告如下。     

THE PHENOTYPE OF MAST CELL IN PRIMARY ADENOID LIVER TUMOR OF RAT AND ITS RELATION TO TUMOR CELL

Mast cells in adenoid liver tumors of 32 rats induced with nitrosomorpholine were observed ultrastructurally, and among them, some were studied immunocytochemically via immunogold techniques. Data indicating that mast cells which located in tumor tissues presented positive expression of rat mast cell protein (RMCP) Ⅰ, Indicating origination from the mucosa mast cells, while those in the connective tissues around tumors were largely stained negatively with either RMCP Ⅰor RMCP Ⅰ antisera, with the exception of only a few cells showing positive RMCP Ⅰ staining. Ultrastructural observation showed that mast cells in tumon contacted closely with the tumor cells. Membranes of the intracytoplasmic granules in these mast cells were fusing together. The content inside the granules were discharged and spread along the intercellular space between the tumor cells. There was not any lesion observed uitrasructrually in the tumor cells contacting with the mast cells. The significance of mucosa mast cells in adenoi     

四君子汤对烧伤豚鼠早期代谢营养的影响

为探讨四君子汤对烧伤早期代谢营养的作用，采用３０％Ⅲ度烧伤豚鼠胃造口模型将４００ｇ左右豚鼠分别在喂养等量热卡、氮和自由进食两种膳食条件下，将３１只豚鼠分为四组，即喂养治疗组（ｎ＝７），喂养对照组（ｎ＝４），自食治疗组（ｎ＝９），自食对照组（ｎ＝１１）予以观察。结果发现：自由进食时，四君子汤能增加摄食量，减轻伤后体重丢失，改善氮平衡，增加肝、回肠粘膜含氮量，而躯壳重及腓肠肌含氮量增加不明显，但静息代谢率则增加；等量喂养时，四君子汤治疗组体重、躯壳重及腓肠肌含氮量显著低于对照组，而肝、肠粘膜重量及含氮量差异无显著意义。此外，四君子汤还可调整激素和内脏组织含水量。因此，我们认为四君子汤对改善烧伤后代谢营养及脏器功能可能是有益的     

浙江医科大学附二院门诊处方中精神药物使用调查

本文对浙江医科大学附属二院１９９３年７月间３１３７８张合格处方进行统计分析，并用限定日剂量（ＤＤＤ）和药物使用指数（ＤＵＩ）为指标，分析镇静催眠药物使用情况。结果表明苯二氮　类药方２０６７张，占总处方量的６．５９％，巴比妥类药方４９张，占０．１６％，麻醉药方１１１张；占０．３５％。苯二氮　类药方中．女性处方量１２０２张，男性处方量８６５张，男、女组间比较有显著性差异。苯二氮　类药方多分布在神经内科，常用的药有舒乐安定和阿普唑仑。九种常用的苯二氮　类药和麻醉性镇痛药的ＤＵＩ均小于１。提示药物滥用现象少见，该院对这类药物的管理比较严格。麻醉性镇痛药中二氢埃托啡处方占６７．５７％。
