外伤性脾切除术后中医证候及免疫功能的研究

目的:研究外伤性脾切除术后中医辨证与免疫功能变化的关系.方法:选择15例脾切除和15例非脾切除患者作为观察对象,以其症状、舌苔、脉象及免疫功能的测定作为观察指标,观察其中医辨证与免疫功能变化.结果:脾切除组在术后早期可出现脾胃虚弱的证候群,同时免疫功能测定补体C3、免疫球蛋白IgG、免疫球蛋白IgM的水平明显降低,与非脾切除组有显著性差异.结论:脾切除容易造成患者术后出现的脾胃虚弱症候群,并降低患者的免疫功能.     

闭孔疝的诊断和治疗

目的探讨闭孔疝的诊治方法。方法对15例闭孔疝病例诊治经过结合相关文献进行回顾性分析。结果15例中．术前确诊率仅20％（3／15），误诊率80％（12／15），全组均行疝环修补术，采用剖腹探查切口。本组治愈率100％，术后切口感染及愈合不良4例（21．67％），随访8例至今无复发。结论术前易误诊、漏诊；对年老体弱、多胎生育伴有不明原因肠梗阻表现的妇女，应高度考虑闭孔疝，Howship—Romberg征及Hannington—Kiff征阳性可确诊。疝环修补术是惟一有效的方法，首选腹腔内入路。早确诊．及时手术是减少并发症、降低死亡率的关键。     

Long-term application of diethylstilbestrol upregulates expressions of μ- and m-calpains in pituitary intermediate lobe of female Wistar rats

BACKGROUND: During formation of prolactin neoplasia, how cells and its structure in adenohypophysis affect prolactin cells should be further studied. Intermediate lobe can be regarded as a driving region to release prolactin (PRL) and may promote formation of prolactin neoplasia in pituitary anterior lobe. OBJECTIVE: To observe the effect of diethylstilbestrol (DES) on the expressions of μ and m-calpains in pituitary intermediate lobe of female Wistar rats. DESIGN: Observational contrast animal study. SETTING: Beijing Neurosurgical Institute. MATERIALS: A total of 21 female Wistar rats, 3 weeks old weighing 70–80 g were housed with free access to tap water and standard pellet food. They were kept in a CL-grade condition, at (24±1)℃ and a humidity of (55±5)%, and with a 12 hours day-night cycle. Caprine anti-μ- and m-calpains antibodies were provided by Santa Cruz Biotechnology, CA, USA; rabbit-anti-PRL antibodies by Dako, Denmark; rabbit-anti-ACTH antibody by Boster Company, Wuhan. METHODS: The experiment was carried out in Pathophysiological Department and Animal Laboratory, Beijing Neurosurgical Institute from August 2006 to January 2007. ① Rats were randomly divided into groups with 7 in each group, including vehicle control group, in which rats were injected intraperitoneally with sun-flower seed oil (1 mL/kg, twice a week) for 16 weeks; DES group, where animals were administered with DES (5 mg/kg, twice a week) for 16 weeks; DES + vehicle control group, in which DES was administered for 12 weeks at the same dose with those in DES group, and then was discontinued and replaced by sun-flower seed oil (1 mL/kg, twice a week) for the following 4 weeks. ② At 16 weeks later, pituitary tissue was dealt with HE staining and PRL immunohistochemical examination to observe evoke of tumor; meanwhile, immunohistochemical examination was used to observe expression of PRL of pituitary anterior lobe, expressions of μ- and m-calpains of pituitary intermediate lobe and distribution of adrenocorticotropin. MAIN OUTCOME MEASURES: ① Expression of PRL of pituitary anterior lobe, expressions of μ- and m-calpains of pituitary intermediate lobe and distribution of adrenocorticotropin. ② Morphological observation of pituitary tissue. RESULTS: All 21 rats were involved in the final analysis. ① Results of immunohistochemical examination: Morphological changes of neoplasia in DES group were strongly positive to PRL, and this suggested that formation of prolactin adenoma was observed in pituitary tissue. As compared with vehicle control group, expression of adrenoeorticotropic hormone (ACTH) was increased in both DES group and DES + vehicle control group. In addition, expressions of μ- and m-calpains in pituitary intermediate lobe were higher in DES group than that in vehicle control group. Otherwise, expressions of m-calpains in pituitary intermediate lobe was decreased in DES + vehicle control group, but expression of μ-calpains was still increased. ② Morphological observation of pituitary tissue: Gland tubes were orderly arranged in rats in vehicle control group. Anterior pituitary gland in rats of DES group demonstrated an apparent disappearance of gland tubes and a relatively large-scaled vasculature formation, namely the vascular lake lined by tightly arranged endothelial cells. Local integrated tumor cell arrangements were also detected. In addition, the border between the IL and the anterior lobe was locally blurred. The definite tumor-like changes in pituitary tissues were confirmed in 6 of 7 female Wistar rats in DES group, and one spontaneous occurrence of tumor formation was found in vehicle control group. In DES + vehicle control group, DES withdrawal led to the subtile emergence of gland tube cavity, although tumor-like cells still existed in 4 of 7 rats, suggesting occurrence of the tumor regression due to the withdrawal of DES. CONCLUSION: A long-term application of DES can enhance the expressions of ubiquitours neutral cysteine protease in pituitary intermediate lobe and this suggests that both of them play a key role in release of hormone and formation of prolactin neoplasia through directly promoting PRL expression and release of neighboring pituitary intermediate lobe.

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％。
