雷公藤生物碱的分离鉴定

我们从雷公藤（ＴｒｉｐｔｅｒｙｇｉｕｍＷｉｌｆｏｒｄｉｉＨｏｏｋ．ｆ．）中按常法分离得到总碱后经ＨＰＬＣ分析出现８个峰，经硅胶柱层析及硅胶ＲＰ－１８反相中压柱层析分离得到５个生物碱，由化学方法和光谱分析证明为雷公藤吉碱（Ｗｉｌｆｏｒｇｉｎｅ２０）．雷公藤次碱（Ｗｉｌｆｏｒｉｎｅ２１），雷公藤春碱（Ｗｉｌｆｏｒｔｒｉｎｅ２２），雷公藤碱戊（Ｗｉｌｆｏｒｉｄｉｎｅ２３），呋喃南蛇碱（Ｃｅｌａｆｕｒｉｎｅ１６）。ＨＰＬＣ分析指出含量最高为雷公藤吉碱，其次为呋喃南蛇碱。     

Psychiatric morbidity, disability and service use amongst primary care attenders in France.

Attenders (n = 124, response rate 84%) of five GPs in Montpellier completed questionnaires on health (reason for visit, cause of problem, GHQ-12), disability (WHODAS II) and service use (CSRI). For each patient, the GP filled in a brief form including a rating of severity of physical and psychological illness. Overall 30.6% of patients were classified as GHQ cases indicating probable non-psychotic psychiatric morbidity and 58.9% were rated as having a physical illness by the GP. Patients with psychiatric morbidity showed as high levels of disability as those with a physical illness, with however a greater number of domains of life affected. They also had a greatly increased number of disability days and used services to a greater extent than those without psychiatric morbidity, these links being stronger than with physical illness. Use of the WHODAS II and the CSRI has not been previously reported in France. This study shows that they could be useful instruments for depicting disability and service use in general practice. The findings from this initial study indicate the need for greater research in primary care focusing on accurate detection and treatment of patients so that disability and excess service use associated with psychiatric morbidity might be reduced.     

D4S1647、D6S2414基因座在中国汉族、蒙古族、藏族的遗传多态性

目的 调查D4S1647、D6S2414基因座在中国汉族、蒙古族、藏族群体中的遗传分布规律。方法 采集308份血及唾液标本应用PCR技术，扩增产物用非变性聚丙酰胺凝胶电泳分离，银染显色分析。结果 两位点各群体基因型频率分布均符合Hardy-Weinberg平衡，每一位点等位基因频率分布在各群体间无显著差异；通过对10个汉族家系的遗传模式分析，证实了两位点等位基因传递遵循孟德尔遗传规律。结论 D4S1647、D6S2414基因座在中国汉族，蒙古族，藏族群体均具有高度遗传多态性。     

保肝解毒胶囊对雷公藤多甙片所致小鼠急性肝损伤保护作用的实验研究

目的：运用新建雷公藤多甙致小鼠急性肝损伤模型，探讨保肝解毒胶囊对该模型肝损伤保护作用的效果和机理。方法：连续5d给小鼠灌服保肝解毒胶囊制剂，而后以雷公藤多甙片造小鼠急性肝损伤模型，检测小鼠血清谷丙转氨酶(ALT)、谷草转氨酶(AST)、还原型谷胱甘肽(GSH-Px)、超氧化物歧化酶(SOD)，肝匀浆中过氧化物(LPO)含量，并取肝组织作病理检查。结果：保肝解毒胶囊可以对抗肝损伤，其疗效和剂量有关；保肝解毒胶囊保护肝细胞的机理与对抗脂质过氧化反应有关。结论：保肝解毒胶囊具有保护肝脏的作用，     

High-dose VP-16 with intermediate-dose cytosine arabinoside in the treatment of relapsed acute nonlymphocytic leukemia

Summary In a study of 11 adult patients with acute nonlymphocytic leukemia (ANLL), infusion therapy with high-dose VP-16 and intermediate-dose cytosine arabinoside was administered. Response was assessed with reference to bone marrow aspirations performed on days 1; 12, 13, or 14; and 21 of treatment. All 7 of the patients with ANLL in relapse achieved marrow hypoplasia, and 3 of them achieved complete response. LFTs were elevated in most patients but no evidence of hepatocellular necrosis was observed. It is concluded that the value of VP-16 in ANLL may have been underestimated in the past because of inadequate dosing.Abbreviations ANLL acute nonlymphocytic leukemia - CGL chronic granulocytic leukemia - DNR daunorubicin - VNC vincristine - ID Ara-C, intermediate-dose Ara-C (500 mg/m² for 12 doses) - HD Ara-C, high-dose Ara-C (3 g/m² for 12 doses) - SGGT serum glutamic transaminase - LDH lactic dehydrogenase - SGOT serum glutamic oxaloacetic transaminase     

Anaesthesia for Treacher Collins and Pierre Robin syndromes: A report of three cases

We present three patients with Treacher Collins or Pierre Robin syndromes who had historical and physical evidence of airway obstruction, difficulty feeding, and sleep disturbances. These preoperative findings correlated with difficult airway management intraoperatively. Based on this experience, we recommend that children with obstructive symptoms have laryngoscopy prior to anaesthetic induction. If the glottic opening is visualized, inhalational induction can proceed. If the glottic structures cannot be visualized, then the anaesthetist must choose between awake oral or nasal intubation, elective tracheostomy, or fiberoptic intubation. In all cases, a tracheostomy tray should be ready and a surgeon experienced in paediatric tracheostomy should be in attendance. After intubation, anaesthesia is best maintained with oxygen and a potent inhalational agent. Extubation should only be done with the patient fully awake and with emergency airway equipment immediately available. Postoperatively, these patients should be transferred to an intermediate care area or intensive care unit where they can be observed closely since delayed complications of airway obstruction are common in this group of patients.     

1280例银屑病患者初发年龄调查报告

调查了1280例银屑病患者的初发年龄,平均初发年龄27.23岁,男性29.25岁,女性23.46岁。初发年龄大多在15～39岁组,占72.96％,最高峰在20～24岁组,占19.53％。初发年龄大小与病情轻重无明显关系,而与病程长短有明显关系,即初发年龄越小者,其病程一般较长。     

飞行人员胆囊结石特点（4218名飞行人员临床调查）

为了了解飞行人员胆囊结石发病、诊治情况、临床特点以及对飞行安全影响等，我们于１９９５年５ 月至 １９９７ 年５ 月随机对４２１８ 名飞行人员进行了临床调查。结果：４２１８ 名中发现胆囊结石患者１８９例，患病率为 ４．５％ 。临床特点：男性多（１８５ 例占 ９７．８％ ）；４０ 岁以上者多（１４３ 例占７５．７％ ）；单纯胆囊结石多（１６８ 例占８８．８％ ）；胆囊多发结石多（１４４ 例占 ７６．２％ ）；有症状胆囊结石多（１１０ 例占 ５８．２％ ）；带石飞行多（１０４ 例占５５．０２％ ）；手术治疗少（７０ 例占３７．０３％ ）。临床调查证实：胆囊切除术是治疗飞行人员胆囊结石安全、可靠、有效的方法，术后能够达到飞行合格标准。结论：对空军飞行人员和民航驾驶员的胆囊结石不论有无症状，在恢复飞行之前必须施行航空医学性胆囊切除术以保障飞行安全
