补肾密骨片结合骨髓移植对桡骨延迟愈合的实验研究

[目的]观察补肾密骨片结合经皮自体骨髓移植对骨折延迟愈合治疗后的骨密度和生物力学性能影响。[方法]预制新西兰大耳白兔骨延迟愈合模型，将75只兔随机分为四组：A组20只，饲料中加入补肾密骨片，骨延迟愈合区注入自体红骨髓2ml；B组20只，饲料中加入补肾密骨片，骨延迟愈合区不注入自体红骨髓；C组20只，饲料中不加补肾密骨片，骨延迟愈合区注入自体红骨髓；D组15只，造成骨延迟愈合模型后，饲料中不加补肾密骨片，骨延迟愈合区不注人自体红骨髓。治疗后12周处死动物取材，行骨密度及生物力学测试。[结果]骨密度及生物力学测试均显示A组骨愈合优于B、C、D组。[结论]补肾密骨片结合经皮自体骨髓移植治疗骨折延迟愈合的骨组织的骨密度及生物力学强度优于单一骨髓移植或中药治疗。     

167例老年人心力衰竭的循证治疗实践

目的:探讨老年人充血性心力衰竭(CHF)的循证医学(EBM)标准化治疗。方法:167例确诊为CHF的住院患者,年龄60￣90岁,平均(74.38±6.84)岁,按照循证医学的基本原理,在病因、诱因和改善心衰症状的基础上,强调能改善预后的神经内分泌拮抗剂的应用。结果:本组167例CHF患者,显效96例(57.5%),有效62例(37.1%),总有效率94.6%,死亡9例(5.4%)。神经内分泌拮抗剂践行率分别为:ACEI类119例(71.3%),β受体阻滞剂69例(41.32%),醛固酮拮抗剂88例(52.7%);随访6￣36个月,平均(16.25±9.30)个月;107例(67.7%)再入院1￣5次,院外死亡6例。结论:按照EBM原理对老年CHF患者制定的个体化治疗方案,效果理想。在老年CHF患者中,神经内分泌拮抗剂践行率较低,可能是再住院次数多的原因之一。     

糖骨康胶囊治疗糖尿病骨质疏松临床研究

目的:观察糖骨康胶囊对糖尿病骨质疏松的治疗作用。方法:将216例患者,遵照随机、盲法、对照原则分为治疗组144例、对照组72例,其中治疗组给予糖骨康胶囊,对照组给予甘露消渴丸,治疗8w后观察疗效。结果:治疗组显效率为40.0%;总有效率为88.6%。对照组显效率为28.9%,总有效率为82.6%。结论:糖骨康胶囊对2型糖尿病骨质疏松有显著的防治作用。     

弱激光血疗法的发展及展望

本文主要介绍了弱激光血疗的机制及其在我国的发展过程.弱激光血疗法起源于前苏联的紫外光量子疗法,传入我国后经历了静脉内照射疗法,离体血液激光照射回输疗法,口咽部照射伴吸氧疗法,鼻腔内照射疗法等.本文对各种疗法的特点及临床应用进行了详细叙述.有些学者认为,中医的观点也能揭示激光血疗的机制.从中医辨证的角度,人的体质分为虚证和实证.结合中医针灸的虚则补之,实则泻之的原理,根据患者的虚实状况,采用含有中医补泻信息的调制激光照射血液,同时加照相关敏感穴位,促进疗效,以体现中医的辨证施治的原则可取得更好的疗效.     

中西医结合治疗慢性肾炎疗效观察及其与血液流变学和微循环的相关意义分析

本文对比观察了中西医结合治疗与单纯西药治疗慢性肾炎的临床疗效,结果表明,前者缓解率及总有效率分别为79.8%和92.1%,显著高于对照组(均P<0.01)。治疗组各临床类型及各中医证型的疗效亦均明显高于对照组相对应的各型肾炎(P<0.05～0.01)。治疗组各型肾炎之血液流变学及甲皱微循环改善均较对照组为显著。两组中完全缓解加基本缓解者,该两类检查指标改善极为显著(P<0.05～0.01),而好转及无效者则无明显改善(P>0.05)。提示临床疗效与之密切相关。     

猕猴桃中药复方制剂对血清SOD及MDA含量的影响

猕猴桃中药复方制剂系采用猕猴桃汁为基质，配加绞股蓝、丹参等中药的有效成分制成。为了研究它的保健作用，在６３例５０岁以上、无急性疾病的中、老年人，３６例３０～４９岁健康的青年，３２例１４～１７岁健康的少年中进行试验，１０ｍｌ每日２次连续服用３０天后，中老年人血液ＳＯＤ显著增高，７０岁以上老人平均增高２．８倍，血清ＭＤＡ明显下降，７０岁以上平均下降８７．５％。

Male suicides and alcohol consumption in the former USSR

A significant decline (34.5%) in the suicide rate occurred in 1984–1988 throughout the USSR. The decline was observed shortly after the introduction of strict restrictions on the sale of alcohol. We tested the hypothesis that the restrictive alcohol policy in the first years of perestroika (June 1985) caused the fall in suicide rates in the former USSR. Data on alcohol consumption, violent death caused by external injury and poisoning (n= 916,315), death due to accidental alcohol poisoning (n= 77,837), suicide (n= 192,305) and death undetermined whether accidentally or purposely (n= 54,253) were analyzed for all former Soviet republics for 1984, 1986, 1988 and 1990. Men were chosen for the analysis, since men are more prone to abuse alcohol than women. Regression analysis with alcohol consumption as the independent variable and suicide rates and violent death rates as dependent variables shows that suicide and alcohol consumption were positively correlated as were violent death and alcohol consumption. In the republics with high alcohol consumption (Slavic and Baltic), suicide rates were also high. In the Caucasian republics, low alcohol consumption was associated with low suicide rates. For most republics, alcohol seems to explain more than 50% of suicides. Alcohol also has considerable explanatory value for violent death. Thus, a restrictive alcohol policy might be a way to reduce suicide and violent death.
