305例老年死亡病例医院感染回顾性调查

本文结果表明,305例老年死亡病例医院感染的发病率为33.8％。感染最多部位为肺部(66.9％),其次为尿路感染(19.4％)。高龄患者,侵袭性操作、多种抗生素联合应用,激素疗法等是诱发医院感染的危险因素。58.8％的病原菌为革兰氏阴性杆菌,37.2％为真菌。31株病原菌药敏结果显示耐药率为33.3％。本文指出合理应用抗生素是预防医院感染的重要措施之一。

慢性乙型肝炎的中医药生态治疗优势

现代医学的生物、心理与社会医学模式特点之一是对以身心疾病为主的现代疾病的预防和治疗 ,更加注重人体的整体性、强调药物作用的多靶点性 ,即整体调节作用。运用中医学的整体观与辩证论治治疗慢性疾病。如肝病的生态治疗就是发挥绿色天然中药复方的多重综合、双向调节功能 ,调动人体的防御机能 ,强调药物作用的多靶点性及整体调节作用以清除病毒、调节免疫、增强抵抗力、恢复肝功能、防止肝炎的慢性纤维化     

10个钨矿职工死因分析

对中南地区10个钨矿1972—1974年入矿(工龄至少1年)的在册职工28453人进行了队列研究。队列成员追访至1989年,死亡2870人,比全国居民死亡率计算的期望值略高(SMR=1.15,95％CI=1.11—1.19);主要是非恶性呼吸道疾病,特别是尘肺(SMR=66.79,95％CI=59.65—73.68)以及与呼吸道疾病相关的肺心病明显超高(SMR=8.19,95％CI=7.42—9.02),比全国居民死亡率高5倍。癌症死亡数在全死因中虽占第一位,但仅鼻咽癌轻度超高(SMR=1.73,95％CI=1.23—2.37),而肺癌死亡率明显偏低(SMR=0.53)。研究结果不支持矽肺与肺癌病因学相关的假说。     

Application of median-effect in quantitative analysis of antitumor drugs in vitro

Objective: To analyze quantitatively the synergistic and antagonistic effects of combined oxymatrine (OMT) and 5-fluorouracil (5-GU) on a cell line of human liver cancer (HepG2) with median-effect principle in vitro. Methods: The median-effect principle and MTT method were used in the quantitative analysis of effects of the two drugs. Results: Cytotoxic activity of the individual drugs enhanced as drug concentration increased. As fa=0.41, a CI equal to 1 indicated additivity; fa<0.41, a CI less than 1 indicated synergy; and fa>0.41, a CI greater than 1 indicated antagonism. The sequence of administration did not influence the cytotoxic activity of the combined antitumor drugs. The ratio of drug concentration was a factor that can influence the killing effect. Conclusion: The combined drugs interaction (CI<1) was synergistic at lower concentration and antagonistic at higher concentration. The ratio of drug concentration is a factor that can influence the killing effect. Biography: HE Song(1965–), male, doctor of medicine, associate professor, Chongqing Medical University, majors in gastroenterology.     

驼背二种截骨术远期效果对比

作者对６３２例强直性脊柱炎并驼背畸形施行二种脊柱截骨矫治术，对其中１３５例病人进行了６～１０年观察，结果表明：７１例椎弓椎体联合截骨效果较好，驼背复发平均３．２°。而６４例椎板截骨效果略差，驼背平均复发１３．５°。经统计学处理，两者对比有显著的统计学意义（ｐ＜０．０１）。作者认为病变未完全静止，截骨术式的选择，术中身体重心前移未彻底纠正，以及外固定时间过短等是影响远期效果的因素。     

烟雾病11例临床分析

自１９８５年至今，我院收治１１例经脑血管造影诊断的烟雾病患者。按照日本厚生省本病诊断标准，９例为确诊病例，表现为双侧颈内动脉末端、前动脉、中动脉起始部狭窄或闭塞，其中６例在双侧颅底可见烟雾状异常血管网，３例见单侧血管网；２例为可疑病例，仪表现为单侧上述异常改变。强调应严格烟雾病的诊断。本组采用颞浅动脉一硬膜脑贴敷术治疗患者１例，效果良好，结合日本该病治疗现状讨论，间接血行再建方法仍不失为烟雾病患者的合理治疗方法。
