目的:研究药剂科积极参与下中西药联合使用对消化内科患者用药合理性的影响。方法:选取我院2014年1月至2015年12月收治且确诊为消化性疾病患者184例,通过随机数表法将患者平均分为对照组和实验组,对照组给予临床常规中西药联合治疗,观察并统计临床反应;实验组给予中西药联合治疗,由本院药剂科参与人员、临床医师联合管理。统计并分析两组疗效、用药合理性及不良反应。结果:对照组总有效率为82.60%,明显低于实验组的94.56%(X~2=5.944,p=0.015);对照组用药合理率为77.17%,明显低于实验组的89.13%(X~2=5.102,p=0.024);对照组不良反应合理率为61.96%,明显低于实验组的88.04%(X~2=18.026,p0.001)。结论:药剂科的积极参与提高了中西药联合使用对消化内科患者的疗效,也降低了不良反应的发生率。  相似文献

This paper discusses possible mechanisms that might lead to misinterpretations of collected data and makes new evidence-based medicine (EBM) recommendations to oppose the previously accepted preventive measures, or treatment options. It is focused on the danger of the “red meat” consumption, and the question whether eating pungent food is good or bad for our health and finally whether the “bad luck” concept of getting several cancer types is valid or not. These three topics got and still have significant media attention. Several mechanisms are proposed as possible causes of these apparent conflicts. Some of them have already been recognized but sadly remained less known to medical readers and also to the general population. Also see the video abstract here https://youtu.be/owjoRXrNShA .  相似文献

Regenerative medicine is a burgeoning field that is important to combat challenging diseases and functional impairments. Compared with traditional cell therapies with evident shortcomings (e.g., cell suspension injection or tissue engineering with scaffolds), scaffold-free cell sheet technology enables transplanted cells to be grafted and fully maintain their viability on target sites. Clinical and experimental studies have advanced the application of cell sheet technology to numerous tissues and organs (e.g., liver, cornea and bone). However, previous reviews have failed to discuss vital aspects of this rapidly developing technology, and many new challenges are gradually emerging. This review aims to provide a comprehensive introduction to cell sheet technology from cell selection to the ultimate applications of cell sheets, and challenges and future visions are also described.  相似文献

ABSTRACT

The Wa spirit world implies a certain rootedness. Knowledge of the location and propensities of spirits is necessary to engage their capricious menace through divination diagnostics and sacrificial remedies. Even as outsiders have attempted to introduce modern medicine, spirit neighbours and enemies continue to figure prominently in Wa health, disease and death. I outline how these practices for managing the menaces of the spirit world survived the demise of the political autonomy of the Wa in the 1950s and 1960s, when the ancient Wa lands were divided and annexed by the nation-states of China and Burma. Finally, I discuss the disastrous consequences of recent forced displacements of large numbers of people, which caused many unnecessary deaths by disrupted the victim’s established ways of dealing with disease as anchored in the local landscape.  相似文献

Human life expectancy in developed countries has increased steadily for over 150 years, through improvements in public health and lifestyle. More people are hence living long enough to suffer age-related loss of function and disease, and there is a need to improve the health of older people. Ageing is a complex process of damage accumulation, and has been viewed as experimentally and medically intractable. This view has been reinforced by the realization that ageing is a disadvantageous trait that evolves as a side effect of mutation accumulation or a benefit to the young, because of the decline in the force of natural selection at later ages. However, important recent discoveries are that mutations in single genes can extend lifespan of laboratory model organisms and that the mechanisms involved are conserved across large evolutionary distances, including to mammals. These mutations keep the animals functional and pathology-free to later ages, and they can protect against specific ageing-related diseases, including neurodegenerative disease and cancer. Preliminary indications suggest that these new findings from the laboratory may well also apply to humans. Translating these discoveries into medical treatments poses new challenges, including changing clinical thinking towards broad-spectrum, preventative medicine and finding novel routes to drug development.  相似文献

大鼠子宫内膜炎模型复制及其中西药复方乳剂治疗   总被引:2,自引:0,他引:2  
目的人工复制大鼠子宫内膜炎模型;应用自制中西药复方乳剂对子宫内膜炎模型大鼠进行治疗。方法对实验大鼠子宫眼观病变、子宫内容物及单侧子宫指数进行检查,对实验大鼠子宫进行病理组织学检查。结果应用3%冰乙酸对大鼠子宫进行刺激,第4天对大鼠子宫接种混合病原菌,能够稳定复制大鼠子宫内膜炎模型;中西药复方乳剂能明显降低大鼠子宫内细菌浓度、种类及单侧子宫系数,能明显减轻子宫的病理变化。结论中西药复方乳剂对子宫内膜炎模型大鼠有良好的治疗作用。  相似文献

目的探讨中药麝香胶囊对小鼠实验性肿瘤的疗效。方法昆明小鼠分别接种艾氏腹水癌、S-180、肝癌细胞株(hepatocellular carcinoma,HCC)三种癌细胞株,接种24h后开始给予中药麝香胶囊,每日1次,共10d。分高、中、低三个剂量给药(4、2、1g/kg以主药麝香药量计)。阳性对照以天仙丸胶囊(1g/kg)一次性灌服。阴性对照组以同体积生理盐水灌服。接种实体瘤动物于第10天处死,称瘤重,计算抑瘤率;接种腹水瘤动物,观察存活时间,计算生命延长率。结果中药麝香胶囊对实体癌有一定的抑瘤作用,但未达到药典规定的抑瘤率30%的要求;对腹水癌也有一定的抑瘤作用,但也未达到药典规定生命延长率50%的要求;统计学分析(P〉0.05)差异没有显著性。结论中药麝香胶囊抑瘤作用不明显,其配方及剂型有待进一步研究与改进。  相似文献
