慢性乙型肝炎伴肝胆结石病人胆汁、外周静脉血、门静脉血中HBsAg和HBV-DNA的存在探讨

对29例慢性乙型肝炎伴肝胆结石患者.采用Elisa和斑点杂交技术检测外周静脉血、胆管胆汁和门静脉血中乙型肝炎两对半及HBV-DNA.并比较HkAg含量.结果，外周静脉血、胆汁和门静脉血中HBsAg浓度分别为;2244.73±59722ng／ml、1181.65±370.91ng／ml、2013.62±483.47ng／ml;HBV-DNA阳性检出率分别为62.07％（18例），72.41％（21例）及68.97％（20例）.提示肝细胞内复制的HHV在进入血循环的同时，部分随胆汁的分泌排入肠道，并可能通过受损肠粘膜进入门静脉再回到肝脏，造成HBV对肝脏的重复感染。     

含化复方新诺明引起过敏性休克一例

含化复方新诺明引起过敏性休克一例患者，女，３０岁，因咽峡炎于１９９２年８月７日晚１０时自行含化复方新诺明（广州白云山制药厂）两片、约７分钟后，出现全身搔痒，当即肌注苯海拉明２０ｍｇ，静推１０％葡萄糖酸钙１０ｍｌ，旋即全身泛起荨麻疹，奇痒难忍，眼睑轻度水肿，嘴唇发麻，咽部“发紧”，发音困难，烦躁，立即给予吸氧，静推地塞米松１０ｍｇ，皮下注射肾上腺素０．５ｍｇ，与此同时，患者脸色苍白、鼻尖、未梢发凉，口唇紫绀，时吸暂停，意识丧失，脉搏１４０次／分，细数，血压测不到，再次给予皮下注射肾上腺素０．５ｍｇ，静点地塞米松１５ｍｇ，并给予扩容、纠酸，约一分钟后，欲行气管切开时，患者呼吸渐恢复、继而意识清楚，紫绀减轻，血压１０／１６ｋＰａ，遂休克纠正。复方新诺明片致过敏性休克者尚属少见，该患者有青霉素过敏史，局部用药又易致过敏，考虑喉头痉挛与药物含化有关。（长治市人民医院王爱军，崔文华，郭天然）含化复方新诺明引起过敏性休克一例@王爱军，崔文华，郭天然$长治市人民医院     

Nerve agent poisoning in primates: antilethal, anti-epileptic and neuroprotective effects of GK-11

 Organophosphorus nerve agents are still in use today in warfare and as terrorism compounds. Classical emergency treatment of organophosphate poisoning includes the combined administration of a cholinesterase reactivator (an oxime), a muscarinic cholinergic receptor antagonist (atropine) and a benzodiazepine anticonvulsant (diazepam). However, recent experiments with primates have demonstrated that such treatment, even when administered immediately after organophosphate exposure, does not rapidly restore normal electroencephalographic (EEG) activity and fails to totally prevent neuronal brain damage. The objective of this study was to evaluate, in a realistic setting, the therapeutic benefit of administration of GK-11 (gacyclidine), an antiglutamatergic compound, as a complement to the available emergency therapy against organophosphate poisoning. GK-11 was injected at a dose of 0.1 mg/kg (i.v) after a 45-min latency period to heavily intoxicated (8 LD₅₀) primates. Just after intoxication, man-equivalent doses of one autoinjector containing atropine/pralidoxime/diazepam were administered. The effects of GK-11 were examined on survival, EEG activity, signs of toxicity, recovery after challenge and central nervous system histology. The present data demonstrate that treatment with GK-11 prevents the mortality observed after early administration of classical emergency medication alone. EEG recordings and clinical observations also revealed that GK-11 prevented soman-induced seizures and motor convulsions. EEG analysis within the classical frequency bands (beta, theta, alpha, delta) demonstrated that central activity was totally restored to normal after GK-11 treatment, but remained profoundly altered in animals receiving atropine/pralidoxime/diazepam alone. GK-11 also markedly accelerated clinical recovery of soman-challenged primates. Lastly, this drug totally prevented the neuropathology observed 3 weeks after soman exposure in animals treated with classical emergency treatment alone. GK-11 represents a promising adjuvant therapy to the currently available emergency polymedication to ensure optimal management of organophosphate poisoning in man. This drug is presently being evaluated in a human clinical trial for a different neuroprotective indication. Received: 16 June 1997 / Accepted: 23 September 1997     

铅性肾病的流行病学分析

我们检查了铅接触人员１０２３名，发现铅性肾病８４例，患病率８．２％。女性３４例（７．２％），男性５０例（９％），男女铅性肾病患病率无显著性差异。印刷厂空气铅浓度平均０．００６９ｍｇ／ｍ３，蓄电池厂为０．１００５ｍｇ／ｍ３，铅矿为０．５ｍｇ／ｍ３。铅性肾病患病率分别为４．７３％，８．３％和２８．５７％（Ｐ＜０．００５）。分析铅性肾病患病率与年龄和铅接触年限的关系。年龄小于３０岁，～４０岁，～５０岁和大于５０岁者，铅性肾病患病率分别为５．５％，８．６％，１２．１％，和１５．６％（Ｐ＜０．０５）。铅接触年限小于１０年，～２０年和大于２０年者，铅性肾病患病率分别为６．６％，９．９％和１３．１％（Ｐ＜０．０５）。     

苯作业工人白细胞降低者的总估校正现患率

选择乡镇工业苯作业工人４次外周血白细胞计数中的间隔半年的两次数据，应用俘获再俘获法，计算其白细胞降低者的总估校正现患率（ＡＣＰＲ）。结果苯接触组为３６．８ｌ％（２９．１４％～４４．４８％），对照组为１２．７１％（７．２０％～１８．２２％）具有显著差异，其相对危险度为２，９。用常规法求得的４次检出率分别是：苯接触组为２６．３７％，１８．７３％，２７．９３％，３６．７６％；对照组为６。８５％，７．３８％，７．９４％，１５．００％。均在其ＡＣＰＲ之９５％可信限内，可见ＡＣＰＲ计算方法简便、结果准确，值得推广。对于稳定的人群，可用其每年一次的健康监护资料计算ＡＣＰＲ。

Sulpiride in negative schizophrenia: A placebo-controlled double-blind assessment

Twenty-four chronic schizophrenic long-stay hospital patients were identified, who had not received neuroleptic drugs for 8–30 (average 8 months) and met or exceeded a minimum criterion of severity of negative symptoms. They were rendomly alocated to either sulpiride 200 mg twice daily or matching placebo, on a double-blind basis for 12 weeks. The results showed that low-dose sulpiride was significantly better than placebo in relation to improvements in negative symptoms. The changes in social behaviour were complex and not obviously related to symptom improvement; exhibited abnormal behaviour, a major factor in preventing successful return to the community, consistently improved only on the active drug.     

Carbohydrate metabolism in children receiving growth hormone for 5 years

Carbohydrate metabolism was evaluated by fasting and postprandial glucose, insulin, and hemoglobin (Hb)A_1c levels in children with chronic renal insufficiency and various other growth disorders treated with growth hormone. Mean fasting and postprandial glucose remained unchanged throughout the 5-year study period in all four study groups. Median fasting insulin levels rose from lownormal levels into the normal range after 5 years of growth hormone. Average fasting insulin level after 5 years was 10 mU/l. Median postprandial insulin values also rose, yet remained within the normal range at the 5-year mark. Mean Hb A_1c levels remained within low to middle end of the normal range in the patients with growth hormone deficiency, Turner syndrome, and idiopathic short stature. Mean Hb A_1c levels at the 5 years were slightly elevated to 6.3% for the patients with chronic renal insufficiency.
