基于混合遗传算法的心脏病决策支持系统研究

将遗传算法和 BP算法相结合 ,建立了一个基于混合遗传算法的心脏病决策支持系统来鉴别诊断五种常见心脏病 (冠心病 ,高血压性心脏病 ,风湿性心脏病 ,慢性肺原性心脏病和先天性心脏病 )。一个含有 35 2份心脏病的数据库用来构建和测试了该系统。实验结果表明 ,构建的系统对这五种心脏病均有较好的诊断识别率 ,系统的平均识别准确性达 90 .6 % ,各疾病的用户准确性和程序准确性均大于 85 .0 % ,表现出良好的心脏病的临床诊断决策支持能力     

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     

医疗纠纷的非诉讼解决方式-医疗纠纷ADR

由于在纠纷解决方面所表现出来的简便，经济，快捷，专业性及保密性强等优点，非诉讼纠纷解决方式（又可译为代替性纠纷解决方式）ADR（Alternative Dispute Resolution）逐渐成为许多国家和地区解决民事纠纷的一大趋势，我国现行医疗纠纷解决机制存在着较多的问题，有待于进一步的改善与完善，根据我国所面临的现实情况，将ADR引入医疗纠纷领域是一条快速，有效地解决医疗纠纷的途径，医疗纠纷的非诉讼纠纷解决方式主要包括仲裁，调解与和解，这3种纠纷解决方式各具特点，适用于不同情况下医疗纠纷的解决。
