解磷注射液救治急性有机磷农药中毒34例临床报告

将急性有机磷农药中毒患者69例随机分为2组,一组主要应用解磷注射液治疗(新疗法34例),另一组(35例)主要应用阿托品治疗。两组治愈率分别为97.1％及77.1％,疗效比较差异显著(P<0.05)。新疗法的优点是起效快,作用持久,疗程短(两组比较P<0.001),副反应轻,值得推广应用。并就应用方法及注意事项等作了探讨,也强调了早期足量用药的重要性。     

核桃仁泥外敷治疗肌肉注射后皮下硬结的疗效观察

采用核桃仁泥外敷治疗１３８例（实验组）肌肉注射后皮下硬结，并与４０例（对照组）采用新鲜土豆片外敷硬结法比较。结果表明：实验组患者治疗１５天后Ⅰ度和Ⅱ度硬结治愈率分别为８１．１３％和４２．２５％，总有效率达９２．０３％，明显优于对照组（Ｐ＜０．００１）。     

Symptomatic liver cyst: Special reference to surgical management

We conducted a retrospective study of 14 patients with symptomatic liver cysts to evaluate current therapeutic interventions for this condition. Abdominal pain (n = 7) or abdominal mass (n = 5) were the most frequent presentations. Three patients also had renal cyst. Percutaneous aspiration with ethanol sclerotheraphy was carried out in 4 patients and all cysts so treated diminished in size, with relief of the symptoms. One patient was treated by aspiration only and re-retension occurred. Cystectomy was performed in 2 patients, unroofing in 5, and fenestration in 2 patients. All patients gained relief of symptoms, with no recurrence of symptoms. Computed tomography revealed that the cysts were diminished or were no longer observable after all the treatments. Our experience indicates that unroofing, fenestration, and cystectomy are safe and suitable procedures for treatment of the condition. Ethanol sclerotherapy may be a feasible alternative to surgical intervention in selected patients. Received for publication on July 23, 1997; accepted on Dec. 25, 1997     

神经生长因子对小鼠突触体内Ca^2＋水平的调节作用

观察了多次海马内微注射ＮＧＦ对小鼠突触体内游离钙水平的影响，并在离体情况下观察ＮＧＦ对ＥＧＴＡ和ＣａＣｌ２分别造成突触体内低钙和高钙状态的调节作用。结果如下：（１）在体实验表明，一定剂量的ＮＧＦ可显著降低老年小鼠海马突触体内游离钙水平（Ｐ＜００５）；（２）离体实验表明，当突触体游离钙水平降低时，适当剂量的ＮＧＦ具有升高游离钙水平的作用；而突触体内游离钙水平升高时，则ＮＧＦ有降低游离钙水平的作用。提示ＮＧＦ对游离钙水平的双向调节作用可能是ＮＧＦ改善老年性记忆衰退的作用机制。     

Self-expanding mesh stent for endoscopic palliation of rectal obstructing tumors: a preliminary report

Summary The endoscopic insertion of self-expanding mesh stents in four patients affected by obstructing rectal malignant tumors is reported. The preliminary experience shows that, in the short term, normal defecation was achieved, with no complications. Longer follow-up is necessary to evaluate the duration and the quality of the palliative effect.     

Endoscopic fistulotomy and biliary drainage as the ultimate palliative treatment for obstruction due to malignant tumors of the papilla of Vater

Summary This report describes the technique and results of endoscopic fistulotomy as a drainage procedure in cases of malignant obstruction of the biliary system from bulky and friable growths in the papilla of Vater. Fistulotomy, coupled with insertion of stents, was successful in seven of eight patients and was associated with relief of jaundice. It is suggested that the method be applied when conventional transpapillary insertion of stents is impossible either due to distortion of the papilla or bleeding of the growth on touch.     

内皮素鞘内注射后的脊髓形态学观察

对18只大鼠进行内皮素脊髓鞘内注射,观察及记录大鼠后肢功能状态,并将18只大鼠分为3个不同的时间处死,进行病理形态学观察。结果表明:3组均表现缺血缺氧病理改变。2及4h实验组病变重于30min实验组。脊髓下胸段、腰段病变重于颈段及骶尾段。同时发现,大鼠后肢的功能状态与其脊髓相应的病理形态学变化不呈正比。     

免疫球蛋白联合鞘内注射激素治疗重症格林-巴利综合征

目的观察免疫球蛋白联合鞘内注射激素治疗重症格林-巴利综合征的疗效。方法应用Hughes量表评价疗效。结果治疗组起效时间明显短于对照组,治疗组Hughes临床分级评分改善明显优于对照组。结论免疫球蛋白联合鞘内注射激素治疗重症格林-巴利综合征可缩短病程、缓解急性期症状。     

胆管残余结石的内镜治疗(附306例分析)

目的：探讨内镜治疗肝内外胆管残余结石的效果。方法：对1994年1月～2004年1月间306例胆道残余结石的治疗效果进行回顾性分析，采用十二指肠镜127例，胆道镜116例，经皮经肝胆道镜(PTCS)63例。结果：306例．1中有286例成功(93．46％)。十二指肠镜治疗127例成功125例；胆道镜经T管窦道治疗116例，成功109例；PTCS治疗肝内结石63例，成功52例。结论：内镜治疗肝内外胆道结石效果显著，可使绝大多数患者避免再次手术。     

6种中药制剂治疗急性脑梗死的成本-效果分析

目的：运用药物经济学的方法对在我院应用的6种中药注射液进行成本-效果分析。方法：271例急性脑梗死患者依据药物治疗方案不同分为6组，即血塞通组、舒血宁组、苦碟子组、疏血通组、川芎嗪组、丹红组，分别观察疗效，并运用药物经济学的方法进行成本-效果分析。结果：疏血通组的成本为3 419.90元，总有效率最高（91.84%），6组间增量成本-效果最低。因此疏血通组是较为合理、经济的方案。
