米利酮对豚鼠心乳头肌及主动脉条的作用

米利酮是非洋地黄，非儿茶酚胺类强心药，具有明显的正性肌力和扩血管作用。国外用于治疗难治性心衰及洋地黄中毒的心衰病人。本文用豚鼠乳头肌及主动脉条进行实验，结果表明合成与进口米利酮的正性肌力作用效价相同，对抗去甲肾上腺素缩血管的作用也等同。

医学美学与美容医学的整体学科研究

回顾医学美学与美容医学形成独立的学科系统的十多年来的发展历程，认为这个新兴学科在“整体学科”方面还存在一些学术问题有待人们进一步探讨。并认为，所谓“整体学科研究”是遵循该学科发展的内在规律所进行的各项研究的总和，是该学科发展的灵魂。学者们的任务在于：通过“整体学科研究”寻求其学科内在规律，经一代代同道有志者坚持不懈的努力，达到学科完善的目的。

Outcome of a conservative approach in severe ulcerative colitis.

BACKGROUND: Severe ulcerative colitis is potentially life threatening even though a policy of intensive medical management and early colectomy in recent years reduced mortality to almost zero. However, colectomy, with or without ileal-anal anastomosis, has its own problems (morbidity, pouchitis, cuffitis) and no reliable prognostic index of surgical outcome has been developed. Intravenous steroids are still the mainstay of medical therapy but their maximal duration before stating a 'treatment failure' has not been defined. AIM OF THE STUDY: To evaluate the effectiveness, safety and outcome of an intensive medical approach in a series of patients with severe ulcerative colitis. PATIENTS AND METHODS: One hundred and forty-nine episodes of severe ulcerative colitis in 115 patients admitted to a Gastroenterology Unit in a 7-year period were retrospectively evaluated. Intravenous glucocorticosteroids--methylprednisolone 1 mg/kg/day--and topical steroids were administered, and supportive treatments with intensive monitoring were extended to all the patients. Second-line strategies for steroid-refractoriness were prolonged glucocorticosteroids treatment, oral ciclosporin, infliximab or surgery. RESULTS: The median number of Truelove criteria at admission was 3 (range 2-5), median CRP 34 mg/l (range 10-196). Median follow-up after discharge was 49 months. In 84 (57%) episodes an early response was noted, while 65 (43%) did not respond within 10 days to the standard steroid treatment. In the non-responders group, 28 patients went into remission with a prolonged steroid treatment (slow responders); 15 patients were treated with ciclosporin (eight responders) and 6 with infliximab (four responders). A total of 24 colectomies was performed in this group of patients (in 21 cases within 30 days from admission). Slow responders showed lower albumin levels (P = 0.02), higher cumulative dose of glucocorticosteroids in the year prior to admission (P = 0.02) and higher age (P = 0.03), in comparison with early responders. Major complications were noted in four episodes which responded to medical treatment. Disease-related mortality was zero. CONCLUSIONS: Medical treatment and use of second-line therapies were effective in the present series of patients. A group of slow responders has been identified and, if an intensive medical monitoring is guaranteed, steroids can be safely prolonged after the first 10 days of treatment. Cumulatively, about 80% of the patients responded to short-term medical treatment, only 5% of the patients underwent colectomy in the follow-up period. Major adverse events were recorded in four patients, who had recovered completely after adequate medical treatment.

目的　探讨医用创面封闭胶在减少肝切除术后肝断面渗血中的价值。方法　 2 0 0 2年 5～ 11月采用信封法将 60例接受肝切除术的病人随机分为医用胶组 (A组 ,n =3 0 )和对照组 (B组 ,n =3 0 )。A组在肝断面彻底止血后滴注医用创面封闭胶 ,B组则不用。测定术后第 1、2、3d腹腔引流液中红细胞 (RBC)数和血红蛋白 (Hb)量。结果　A、B两组术后腹腔引流液中的RBC数和Hb量均以第 1d为高峰 ,显著高于第 2、3d(P <0 0 5) ,其中A组术后第 1d腹腔引流液中RBC数及Hb量均显著低于B组 (P <0 0 5) ,只相当于B组第 2d的水平。A组主要并发症发生率低于B组 ,但差异无统计学意义 (P =0 0 7)。结论　医用创面封闭胶可有效抑制肝切除术后早期的肝断面渗血 ,有助于降低术后并发症的发生率
