复苏饮对重症脑出血患者血清NF-α、IL-1、IL-6影响的临床研究

[目的]观察复苏饮对重症脑出血患者血清炎症细胞因子TNF-α(肿瘤坏死因子-α)、IL-1(白细胞介素-1)、IL-6(白细胞介素-6)释放的影响作用.[方法]根据双盲随机试验的方法将入住icu的重症脑出血患者随机分为2组.对照组(131例)和中药组(140例).对照组给予传统的西医治疗方法脱水、降颅压、止血等,中药组是在此基础上加用复苏饮.在治疗前及治疗后的48h检测TNF-α、IL-1、IL-6的含量,比较治疗前后炎症因子的变化差异.[结果]两组炎症因子在用药前后都有下降,但程度不同,以中药组下降明显,两组差异比较有统计学意义.[结论]复苏饮可以降低重症脑出血患者在急性期的炎症因子释放,从而对脑出血有良好的治疗作用.     

我国中草药中农药残留的特点

中药及其制剂的农残超标问题已成为制约我国中药出口的重要因素之一。中药的种植、运输和生产过程都会造成中药材的农药污染。中药的农药污染随产地、药用部位、生长期、炮制方式的不同而有所不同。目前中药的农药污染已经降到一个相对比较低的水平,但有机氯类农药的检出率接近100%,部分中药超标。     

眼用制剂研发过程中应关注抑菌剂的合理使用和质量控制

眼睛是人体的重要感觉器官,是人类与外界交流的重要工具。眼用制剂作为直接用于眼部发挥治疗作用的无菌制剂,它的安全性一直为人们所关注。近年世界各国对眼用制剂的质量要求已逐渐向注射剂的质量要求方向发展。目前,国内市场使用的眼用制剂大多数为多剂量包装,制剂一旦开封后,容易在使用和保存过程中被泪液及空气中的微生物污染,从而产生安全性隐患。为了防止眼用制剂在使用中被微生物污染,大部分眼用制剂(包括抗生素类)中都添加了抑菌剂。抑菌剂又称防腐剂,是指能防止或抑制病原微生物生长与繁殖的化学药品,通过干扰微生物有机体的生长、…     

高压氧治疗早发甲低患者血清皮质醇水平的变化及临床意义

目的:研究高压氧治疗早发甲低患者的血清皮质醇水平,探索高压氧影响甲状腺功能的机制。方法:早发甲低患者42例,随机分为高压氧治疗组和对照组,每组21例,治疗前后测定血清皮质醇水平。结果:治疗组患者血清皮质醇水平较治疗前升高,且统计学差异显著(P<0.05)。对照组血清皮质醇水平未见明显变化。结论:高压氧干预可提高患者血清皮质醇水平,可能是促进甲状腺激素分泌的重要因素。     

大黄素对大鼠腹腔巨噬细胞产生的TNFα、IL-1、IL-6及细胞[Ca2+]i的影响

目的 研究中药大黄有效成分大黄素对不同状态下的巨噬细胞分泌TNFα、IL-1、IL-6和[Ca^2 ]i的方法。利用脂多糖（lipopolysacchride,LPS)刺激的大鼠腹腔巨噬细胞作为过度炎症反应的体外模型,用生物学方法和荧光分光光度法测定巨噬细胞合成分泌的TNFα、IL-1、IL-6和[Ca^2 ]i。结果 大黄素对TNFα的分泌和[Ca^2 ]i有双向调节作用。结论 大黄素可能具有免疫双向调节功能。

Enamel distribution, structure and mechanical alterations in col1-caPPR mice molar

Enamel mineralisation is a highly controlled process in which the deposition, growth, and maturation of inorganic crystallites are regulated by secreted matrix proteins at the molecular and cellular level. Maxillary and mandibular first molars from the col1-caPPR mutants as well as normal controls aged for 12 weeks were observed by SEM and nanoindentation, respectively. Several types of aberrations in enamel distribution and crystal organisation were encountered in the transgenic molars. Also, the gene alteration resulted in degradation by as much as 23.42% in hardness and 17.56% in the elastic modulus. These data suggested that gene mutation altered the ameloblastic differentiation and movement, resulting in variations of crystal arrangement patterns, aberrations of enamel distribution, and degradation of mechanical behaviour. Furthermore, the col1-caPPR mouse model was determined as useful for studying how the genes modulate the biomineralisation process.     

运动神经元病患者肺功能改变的临床研究

目的探讨运动神经元病肺功能受损情况及病理生理原因.方法测定54例患者的肺功能并与正常对照组进行比较.结果患者通气功能明显减低(P＜0.01),以限制性通气障碍为主要损害占70%以上,小气道受损约占60%,弥散功能受损占48.14%.结论运动神经元病患者肺功能损害以限制性通气障碍为主.其肺功能损害的病理生理是由于支配呼吸肌的神经元进行性减少,呼吸肌出现失神经萎缩,呼吸肌无力而出现一系列肺功能改变.     

吸烟对精神分裂症男性患者精神病理症状的影响

Objective To compare the differences of psychopathologic symptoms between smokers and non-smokers in chronic and first-episode,drug-nalve schizophrenics.then it was attempted to explain the reasons why there is higher rate of smoking behavior in schizophrenia.Methods In all.427 male chronic schizophrenic patients(332 smokers and 95 non-smokers)and 63 male first-episode drug-naive patients with schizophrenia(22 smokers and 41 non-smokers)were collected.All patients were assessed with the Positive and Negative Syndrome Scale(PANSS).Results In chronic patients.the item scores of poor rapport and passive/apathetic social withdrawal of PANSS negative subscale were significantly lower in smokers than non-smokers(3.9 ±1.5 vs.4.4±1.7;3.6±1.6 vs.4.0±1.7.respectively,P＜0.05),and so was the total scores of PANSS negative subscale(24.0±8.2 vs.26.3±9.5).In first-episode.drug-ndive patients.the itern scores of emotional withdrawal and passive/apathetic social withdrawal of PANSS negative subscale were significant lower in smokers than non-smokers(2.7±1.3 vs.3.5±1.3:2.7±1.3 vs.3.5±1.4,respectively,P＜0.05).Conclusion It is suggested there are positive effects of cigarette smoking on the psychopathological symptoms of patients with schizophrenia,which misht be one of the mechanisms for higher rates of smoking behavior in schizophrenia.
