Indoor air pollution of coal fumes as a risk factor of stroke, Shanghai.

A cohort of 957 male persons in Shanghai has been followed up for 12 years after they entered a screening program for coronary heart disease and stroke. During the period of study, 24 of the subjects who had no previous history of heart disease and stroke died from stroke. Risk factors for stroke were analyzed by the Cox proportional hazards model. Coal fumes were found to be an independent risk factor for stroke in addition to diastolic blood pressure, age, and cigarette smoking.     

"气口独为五脏主"探析--《内经》脉学探析之二

在回顾《内经》、《难经》关于“气口独为五脏主”论述的基础上，指出：气口诊脉可测知全身气血盛衰、胃气的强弱、经脉的变动、五脏六腑的功能状态，以及外邪入侵后，人体疾病的阴阳、表里、虚实、寒热等变化。强调“气口诊脉”至今仍是中医诊脉的主要方法之一。     

Effect of omeprazole on the anticoagulant activity and the pharmacokinetics of warfarin enantiomers in rats

The effect of the proton pump inhibitor omeprazole on the anticoagulation and the pharmacokinetics of warfarin enantiomers was studied in rats. Omeprazole given intraperitoneally in a daily dose of 0.67 mg/kg over 8 days had no significant effect on the absorption, distribution and the total serum clearance values of the S- and R-enantiomers of warfarin. Omeprazole did not affect the pre-treatment baseline blood coagulation and the in vitro rat serum protein binding of warfarin enantiomers. In vitro study with rat liver microsomes showed that omeprazole had an inhibitory effect on the hydroxylation of warfarin enantiomers. Results obtained from in vivo urinary excretion study revealed that omeprazole inhibited the formation clearance of both S- and R-form oxidative metabolites, but increased that of the overall reductive metabolites, and the renal clearance of S- and R-enantiomers, of warfarin. As a consequence, the total serum clearance values for warfarin enantiomers remained unchanged and the hypoprothrombinaemic response produced by warfarin was not affected.     

腰椎间盘术后椎间盘炎的诊治

目的：探讨腰椎间盘术后椎间盘炎的病因。早期诊断和治疗问题。方法：分析10例术后腰椎间盘炎的临床表现、血象、血流变化、血和病灶细菌培养、腰椎X线平片、CT、MRI所见在发病后的敏感程度，比较3例非手术与7例经前路腹膜后（2例联合后入路）病灶清除，一期椎间植骨融合本治疗的效果。结果：不同程度的发热、痉挛性腰痛、血流增快是本病的特点。MRI、CF、X线片三者的诊断敏感性存在时间差，分别约为发病后1、3、5周。仅2例血和病灶细菌培养均阳性。前路减压植骨融合术减少全身性抗生素和镇痛剂的使用量，明显缩短病程。结论：ESR、MRI对早期确诊、引导手术价值较高。高热、痉挛性腰痛、血沉增快三者具一持续2周得不到控制，可考虑及早手术。手术疗法近期效果更为确切。     

脉君安与巯甲丙脯酸,硝苯吡啶联合应用治疗高血压病临床分析

１３２例高血压病患者随机分为二组，观察组７６例采用脉君安与巯甲丙脯酸、硝苯吡联合应用。对照组５６例采用巯甲丙脯酸、硝比啶联合应用。共用４周，结果降压总有依次为９７．３６％、８５．７１％；副作用发生率依次为２．６３％、，１７．８６％。未见明显的电解质、血糖和血脂变化，提示脉群安与巯甲丙酸，硝苯吡啶联合应用可以提高降压疗效减少副作用。     

一种直接高效克隆PCR产物的载体制备

Ｂｌｕｅｓｃｒｉｐｔ经ＥｃｏＲ Ｖ酶切后，在Ｔａｑ酶作用下加入ｄＴＴＰ使其３’端加上碱基“Ｔ”而成为３’端突出的粘性末端载体。用此载体直接与ＰＣＲ产物连接进行克隆。克隆效率比采用平端载体克隆的效率提高约５０倍。     

蝶塞及毗邻关系的解剖对蝶窦手术重要性探讨

蝶窦居于颅底，毗邻结构复杂，常有变异。本文报告开展各类型蝶窦手术１２５例，并就蝶窦区域应用解剖对蝶窦手术的重要性，进行研究与探讨。     

地中海贫血红细胞系超微结构改变的研究

本文报道了6例地中海贫血红细胞系列的超微结构改变,包括中、晚幼红细胞,网织红细胞及部份成熟红细胞的胞浆及胞核内可见电子密度较高的包涵体(α或β肽链的沉积);核膜有缺失或重叠,核周间隙扩大;各期红细胞中易见自噬泡和空泡形成;红细胞外形变化显著,发现有特征性的棒形红细胞。此外,还观察到红细胞在狭窄的脾窦中被扣押、挤压、破坏的现象。上述变化提供了地中海贫血发病机理的形态学证据     

彩色多普勒血流显像对肺良、恶性肿瘤鉴别诊断的应用

本文应用彩色多普勒血流显像技术对４０例肺肿瘤患者进行研究。全部病例均经手术及病理证实。结果表明：肺恶性肿瘤的内部及周边血流丰富，搏动指数（ＰＩ）和阻力指数（ＲＩ）低于肺良性肿瘤。因此，通过观察肺肿瘤的血流丰富程度及ＰＩ（界值＜１），ＲＩ（界值＜０．５）．可做为辨别肺恶性肿瘤的参考条件。
