急性氯气中毒32例临床分析

1997年9月4日晨,我市北郊顺河造纸厂储氯罐管道破裂,工业用氯大量外泄,造成附近中学及农村人群因吸入氯气急性中毒。除1例因年老体弱,原患慢性支气管炎、肺气肿而当时死亡外,其余32人急送我院抢救。现在抢救情况报告如下。 1 临床资料: 1.1 一般资料:共收治32例,有28例于发病后2～3小时入院,4例于24小时后入院。男16例,女16例,年龄11～15岁12例,16～20岁6例,41～45岁1例,46～50岁3例;50岁以上有4例。其中最小年龄为11岁,最大为65岁。职业:教师6例,学生18例,农民7例,工人1例,住院天数≤5天为12例,6～10天为14例,11～15天5例,32天1例。原患慢性支气管炎3例,慢性肝炎1例,高血压病1例。     

CT对腹膜后肿瘤的诊断体会：附13例分析

ＣＴ检查可以较清楚了解腹膜后肿瘤的大小、部位、范围，及与周围组织器官的关系，有时可提供定性依据。本文分析经手术病理证实的１３例腹膜后肿瘤ＣＴ表现，结合文献复习，以提高对腹膜后肿瘤诊断的准确性，为治疗提供更多的依据。一、资料和方法本组１３例中，男８例，...     

艾滋病毒受抗体包围仍有感染力

艾滋病毒受抗体包围仍有感染力科学家最近发现艾滋病病毒在能抑制其活力的抗体包围下仍具有感染能力，这一发现有助于解释为什么艾滋病病毒难以根除。美国弗吉尼亚英联邦大学的一个科研小组对人体淋巴结内一种称为ＦＤＣ的细胞进行了研究。这种细胞中含有大量艾滋病病毒，...     

现代传媒应慎为酒唱赞歌

酒,源起何时,出自哪个国家,目前尚无确实考证。随着时间的推移,目前,酒的品种却是日新月异的多了起来,饮酒的人更是遍布大地各个角落,或老人,或青年,或少年,或男人,或女人,其人数之多可能超过吸烟的人数。 酒对人体健康的益害如何,世人众说纷纭。 历代文人墨客极度渲染酒的兴     

益气养阴活血法治疗冠心病心律失常有效性和安全性的Meta分析*

[摘要]目的 系统评价益气养阴活血法治疗冠心病心律失常的有效性及安全性。方法 检索中国知网数据库（CNKI）、维普中文科技期刊全文数据库（VIP）、中国学术期刊数据库（万方）、Cochrane图书馆、Web of Science和PubMed中有关益气养阴活血法治疗冠心病心律失常的临床随机对照试验研究,提取纳入研究的相关数据并进行方法学质量评价。应用RevMan5.3软件进行Meta分析。结果 共纳入26个研究。Meta分析结果显示,益气养阴活血法治疗组在临床总有效率[OR=3.47,95%CI（2.68, 4.48）,P<0.00001]、24h心律失常事件数[WMD=-204.82,95%CI（-228.78, -180.86）,P<0.00001]、中医症候疗效[OR=3.08,95%CI（2.04,4.66）,P<0.00001]、心电图疗效[OR=2.50,95%CI（1.63,3.83）,P<0.0001]、血液流变学指标：全血高切黏度[WMD=-1.02,95%CI（-1.18,-0.85）,P < 0.00001]、全血低切黏度值[WMD=-1.66,95%CI（-2.00,-1.33）,P< 0.00001]、血浆比黏度[WMD=-0.42,95%CI（-0.50,-0.35）,P < 0.00001]、纤维蛋白原[SMD=-1.67,95%CI（-2.06,-1.28）,P <0.00001]及安全性[OR=0.41,95%CI（0.27,0.61）,P<0.001]方面均优于常规西医治疗组。结论 益气养阴活血法治疗冠心病心律失常具有更好的有效性及安全性。由于目前纳入文献数量及质量的限制,期望今后有更多高质量的随机对照试验支持。     

受微波高频辐射人员外周血5—羟色胺含量的变化

The relationship between 5-HT contents in peripheral blood and power density among workers exposed to microwave or high frequency radiation in the workshops were studied. At the same time, systems and disorder of central nervous system and cardiovascular system were examined. The results of study showed that the average 5-HT content in whole blood for high frequency radiation exposure group was lower than that of the control, but without statistical significance. Value for the microwave exposure group was significantly lower than that of the control (P less than 0.01). The 5-HT content of mechanical maintainers exposed to microwave of high frequency radiation were all lower than the contents of their corresponding control groups (P less than 0.01). But for the mechanic operators as compared with their corresponding control, no significant difference was found (P greater than 0.05). The power density exposed by the maintainers of both tested groups were all higher than that of the operators. The 5-HT contents in the whole blood were inversely proportional to the power density of microwave and high frequency groups. The incidence of neurasthenic syndrome, unsymmetric skin temperature in both limbs and hypotension was higher in the microwave and high frequency radiation groups than that in the control group. The incidence of bradycardia and some abnormal items of electrocardiograph in the microwave group was obviously greater than that in high frequency group, which may be related to different frequency exposed for these two exposure groups. Whether it is related to the contents of 5-HT needs further investigation.
