蒙医陶拉布日疗法简介

被称之为蒙医传统五种疗法之首的陶拉布日（下泻）疗法在临床应用有越来越少的趋势。这主要是因为陶拉布日疗法的服药方法略繁琐所致。陶拉布日疗法服药方法有三个步骤：即下泻施治前的准备，泻药的使用和善后调理。服药前的准备又有远近之分。泻药的使用包括配方、服法、洗肠、下泻程度和辅助疗法等五个部分。陶拉布日疗法又分为峻泻剂与缓泻剂两种。缓泻剂可无需实施施治前的准备和善后调理，直接用药，不会影响患者的工作学习，所以被广泛应用于临床。     

急慢性肠系膜缺血性疾病的手术治疗

尽管近年来外科诊治水平发展很快，但对肠系膜缺血的治疗因认识不足而被延误的状况仍未得到根本改变，病死率仍高达60％以上，有的医院甚至高达100％。其原因，一是本病少见，只占住院病人的7％-13％；对于一名外科医生来说，其一生处理过的肠系膜缺血病人也不足十余例，没有更多的经验。另一个原因也是因为本病发病率低，在遇到急腹症时较少想到本病。等到诊断清楚以后，为时已晚。如能在遇到急腹症时想到了肠系膜缺血，并采用各种手段排除或确定它，就会减少对本病的延误，从而根本改变目前诊治本病的现状。     

Experimentally induced ileal ulcers in rats. A model to study non-specific inflammatory bowel disease

A surgical technique was used to establish chronic intestinal ulcers in Sprague-Dawley rats. A 2-cm-long segment of the distal ileum was excised and left attached on the mesentery. The ileum was reanastomosed. The excluded ileal segment formed a 'cyst' of various sizes. Initially, the anastomoses healed well, but after 6-8 weeks para-anastomotic ulcers developed in more than 50% of the rats. Histopathology showed a chronic inflammatory reaction with a predominance of mononuclear cells and increased numbers of eosinophilic granulocytes. The surface of the ulcers was covered with bacteria. Penetrating ulcers with fistula formation occurred. It is concluded that this experimental model may be useful for time sequential studies of the development of chronic and ulcerative ileitis. It may also be used to study the effect of medical and surgical regimens for the treatment of non-specific chronic inflammatory bowel disease.     

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。     

Acute effects of serotonin on rat bladder contractility.

INTRODUCTION: The purpose of this study is to investigate in vitro the effects of serotonin on the rat detrusor. In particular, it examines which drugs inhibit the serotonin-induced detrusor contractions. MATERIALS AND METHODS: Isometric tension changes of isolated rat bladder muscle strips were recorded in an organ bath using a force transducer. Acute effects of serotonin (0.0001-0.01 mM) on resting tension were assessed. Electrical field stimulation (EFS); bethanechol (0.0001-0.01 mM); ATP (1-3 mM)- or KCl (63.5-254 mM)-induced contractions using an application in an organ bath were compared with serotonin-induced contractions. In order to examine the action mechanism of serotonin-induced stimulation, EFS-, bethanechol-, ATP- or KCl-induced contraction on serotonin treatment (0.001 mM) was assessed and serotonin (0.001-0.1 mM) was cumulatively added to the organ bath following preincubation with propranolol, ketanserin, tropisetron, propiverine, sodium nitroprusside or doxazosin. RESULTS: The serotonin-induced response has two phases: an initial transient contraction and a prolonged tonic phase. Serotonin produced a reversible and dose-dependent contraction of the detrusor strips. Responses to bethanechol significantly increased with a concentration of 0.001 mM serotonin (p < 0.05). There was no effect on the responses to ATP, KCl, or EFS on 0.001 mM serotonin. The 5-HT(2) receptor is mainly responsible for serotonin-induced contractions of the detrusor (p < 0.05), while the 5-HT(1) receptor is partially responsible. Doxazosin and propiverine each significantly suppressed the response to serotonin, while sodium nitroprusside and tropisetron each had no effect (p < 0.05). CONCLUSIONS: Because the 5-HT(2) antagonist blocked the effect of serotonin-induced bladder contractions and the stimulation of the adrenoreceptors, the 5-HT(2) antagonist seems to improve lower urinary tract symptoms.     

透明质酸钠玻璃体腔内充填在严重开放性眼球损伤治疗中的应用

目的 研究透明质酸钠玻璃体腔内充填对严重开放性眼球损伤预后的影响。方法 在严重开放性眼球损伤一期手术缝合后玻璃体腔内充填透明质酸钠至眼压Tn。结果 用透明质酸钠在玻璃体腔内充填，眼球萎缩的发生率（6．67％）明显低于用BSS液充填的发生率（70．58％）。结论 透明质酸钠玻璃体腔内充填在严重开放性眼球损伤治疗中的应用对眼球外形维持和视功能恢复有重要作用。     

Hypoxia effects on vascular endothelial growth factor derived epithelial cells of nasal polyps]

OBJECTIVE: To understand the role of nasal mucous epithelial cells to hypoxia in early stage of nasal polyps(NP) formation. METHODS: Epithelial cells of NP and inferior turbinate (IT) were cultured without serum under normal oxygen and hypoxia, and stimulus of inflammatory cytokines. Erythropoietin (EPO) was regarded as hypoxia mark, and expression of vascular endothelial growth factor(VEGF) mRNA and protein derived from epithelial cells were detected respectively by in situ hybridization and ELISA. RESULTS: 1. Under hypoxia, EPO mRNA was expressed intensely in epithelial cells from NP and IT, and there was no significant difference between both of them. This result suggested that EPO might be regarded as a hypoxic mark. 2. The ability of producing VEGF mRNA increased with cytokines stimulation, especially under hypoxia. Protein level of VEGF from epithelial cells of NP and IT increased with cytokines stimulation, especially in hypoxia and was time-dependent. CONCLUSION: Epithelial cells actively produce vast VEGF under hypoxia. The VEGF induced by hypoxia of the mucosa in middle meatus is of importance in the formation of nasal polyps(NP) in early stage, which may be the major cause of NP formation in middle meatus.
