Periodontitis, a risk factor for cardiovascular diseases?

Exist a statistically significant association between a diagnosis of coronary heart disease and certain oral health parameters. These parameters are independent and more strongly associated with coronary heart disease than were recognized risk factors, such as serum cholesterol levels, body mass index, diabetes and smoking status. The correlation between serum and salivary cholesterol concentration and the role of salivary lipids in oral health have been poorly characterized. Lipids in saliva are mostly glandular in origin, through some may diffuse diffuse directly from the serum. The surface of the enamel (in case of dietary fat which have an cariostatic effect) is protected against demineralization by a mixture of salivary lipids and proteins. Salivary lipids may have anucleating role in the early mineralization of the dental plaque. The prevalence of periodontal disease may be increased in patients with atherosclerosis, and dental and periodontal infections have been shown to be associated with occurrence of acute and chronic coronary heart disease. Among the known risk factors of atherosclerosis, high serum lipid levels, especially cholesterol may be important with regard to periodontal health.     

犬失血性休克早期血浆3种酶活性值的变化

用１０只犬复制失血性休克模型,观察休克前、休克３０ｍｉｎ及回输血后３０ｍｉｎ时,血浆中心肌相关酶—肌酸激酶（ＣＫ）、谷草转氨酶（ＧＯＴ）、α－羟丁酸脱氢酶（ＨＢＤ）活性值的变化。结果发现：失血性休克３０ｍｉｎ时,ＣＫ、ＧＯＴ较休克前显著下降（Ｐ＜０．０５,Ｐ＜０．０１）;ＨＢＤ值也下降,但无统计学意义（Ｐ＞０．０５）。输血后３０ｍｉｎ时,ＣＫ、ＧＯＴ、ＨＢＤ值回升,与休克３０ｍｉｎ时比显著升高（Ｐ＜０．０５）,与休克前比无显著性差别（Ｐ＞０．０５）。提示：失血性休克早期心肌细胞可能存在有一种保护性反应,心肌细胞没有发生明显损伤。     

我国农村地区实施大病统筹合作医疗或医疗保险方案的技术缺陷

在我国中等发达及上农村地区,大病统筹合作医疗或医疗保险以其可缓解农村居民的就医经济风险而受到欢迎,但是在方案的拟订过程中尚存在一些明显的技术缺陷,比如,“大病”的技术定义、农村居民就医经济风险分析、风险临界线界定、保险经付比测算和保险费率厘定等,这些技术的缺乏,已严重影响农村合作医疗或医疗保险的推广和实施效果。     

The ocular changes in patients on chronic dialysis

The paper propose the study of lacrimal secretion alterations, the lacrimal level of the urea and the fundus optic alterations at the patients with chronic renal failure, during the hemodialysis. For the study we used the general ophthalmologic examination, the fundus optic examination before and after the hemodialysis, the lacrimal secretion examination by Schirmer l-test and the measure of lacrimal urea by the Berthelot modified method. The study was done on a member of 30 patients, with chronic renal failure, having a age of the dialysis between one and 80 months. The results of the study showed lacrimal hyposecretion, the urea lacrimal level being lower than the urea blood level and a concordance between the lacrymal and sanguine clearance of the urea. The fundus optic examination during the hemodialysis showed a pale aspect of the fundus the pallidity being more pronounced before the dialysis with filiforme arterioles, apparently without content, significant for decreasing of the circulatory debit.     

小分割分次立体定向放射治疗脑转移瘤近期疗效观察

目的观察小分割分次立体定向放射治疗(fractionated stereotatic radiation therapy,FSRT)脑转移瘤的近期疗效.方法15例病人单纯全脑外照射(WBRT组),中间平面剂量20～40Gy/10～20次/2～4周.17例病人接受FSRT(FSRT组),每次分次剂量为2.5～3.0Gy.其中11病人行单纯FSRT,中心总剂量为30～60Gy/1 0～20次/2～4周;6例病人先行WBRT,然后行FSRT,中心总剂量为46～60Gy/5～6周.结果KSP评分增加10分以上者,WBRT组为5 3.3%,FSRT组为82.4%.(P＜0.05).WBRT组有效率(CR PR)为50.0%;FSRT组有效率(CR PR)为80.0%.中位生存率:WBRT组为3.5月,FSRT组为10.0月.结论FSRT能有效地控制脑转移瘤,减轻神经系统症状,提高生存质量,延长病人生存期,而没有增加副作用,值得临床推广应用.
