同型半胱氨酸(homocysteine,Hcy)是一种反应性血管损伤氨基酸,高Hcy血症是心脑血管等疾病的独立危险因素。近几年来,人们发现Hcy与糖尿病也有关,高Hcy血症可能是糖尿病大、小血管并发症发生、发展的一个重要因素。 相似文献

[目的]探讨冠心病、脑梗死患者血浆同型半胱氨酸(Hcy)浓度及相关因子与发病危险因素的关系。[方法]2002-2004年在北京铁路总医院筛选出冠心病组、脑梗死组及正常对照组进行血浆Hcy浓度、血清叶酸、维生素B12质量浓度、血糖、血脂测定,观察各组与指标间的关系。[结果]冠心病组、脑梗死组血浆Hcy浓度比正常对照组明显增高,均有显著差异性(P〈0.05);冠心病组、脑梗死组血清叶酸、维生素B12质量浓度与正常对照组比较,差异均无显著性(P〉0.05);血脂、血糖升高患者中血浆Hcy浓度与血脂、血糖正常患者比较,差异均无显著性(P〉0.05)。[结论]高同型半胱氨酸血症是心脑血管疾病的独立危险因素。 相似文献

基因背景不仅在决定个体对疾病的易感上起重要作用,而且还与疾病的发生、发展有着密切的关系。近年来,高同型半胱氨酸血症(HHcy)与一些疾病如动脉粥样硬化、冠心病、心脑血管疾病、糖尿病等的发病关系日益受到人们的关注。血浆同型半胱氨酸(Hcy)代谢过程中相关代谢酶的基因多态性与这此致疾病的关系成了近年来研究热点。 相似文献

Hcy是蛋氨酸代谢的中间产物,参与体内一碳单位的转移,它作为机体内一种正常的生理物质,对体内许多代谢反应和某些物质生理功能的发挥具有重要作用。许多研究显示,高同型半胱氨酸血症在动脉粥样硬化和血栓栓塞性疾病如脑血管病、冠心病和静脉血栓等的发病机制中起重要作用,已被认为是独立的危险因素之一。本文对高同型半胱氨酸(Hyperhomocysteinemia,HHcy)与疾病的关系作一综述。主要包括Hcy的认识历史、Hcy与相关疾病的关系、Hcy检测及影响因素、作用机制及HHcy的防治等。 相似文献

OBJECTIVE: Although nausea and vomiting of pregnancy is the most common medical condition during pregnancy, there are many unanswered questions regarding its cause, epidemiologic features and optimal management. The objectives of this study were to ascertain the prevalence of nausea and vomiting in a sample of Canadian women, to characterize the distribution of their severity and to investigate the role of vitamin B6 deficiency in their etiology. DESIGN: Prospective study. SETTING: Antenatal counselling service for pregnant women. PATIENTS: Three cohorts of women: a prospective, population-based cohort of 193 women, to estimate the rate and severity of nausea and vomiting (cohort A); a cohort of 555 women who sought advice for nausea with or without vomiting, to study the correlation between the maximal daily number of episodes of vomiting and maximal weight loss (cohort B); and a prospective cohort of 301 women who reported vomiting, to correlate vitamin supplementation with vomiting (cohort C). INTERVENTIONS: All 3 cohorts were interviewed during the counselling session, and cohort B was followed up prospectively. OUTCOME MEASURES: Frequency of nausea and vomiting, weight loss, maximal number of daily episodes of vomiting, rate of multivitamin supplementation. RESULTS: Overall, 67% of the women in cohort A reported experiencing nausea or vomiting, or both; 22% reported vomiting, and 9% experienced weight loss. In cohort B there was a significant correlation between the maximal number of daily episodes of vomiting and maximal weight loss, although there was wide variation (r2 = 0.25, p < 0.001). There was a highly significant correlation between the number of daily vomiting episodes and mean weight loss (r2 = 0.99). In cohort C, vomiting was significantly associated with lack of supplementation with multivitamins before 6 weeks' gestation (p = 0.002). CONCLUSIONS: The relation between number of daily vomiting episodes and mean weight loss may serve as a clinical tool to assess the severity of nausea and vomiting in pregnancy and the success of anti-emetics and rehydration regimens. Further study is needed to elucidate the biologic basis of the observed association between vomiting and lack of multivitamin supplementation in early pregnancy. 相似文献

心血管疾病是我国的多发病和人群的主要死亡原因之一,而高血压已成为中老年人的常见病,是冠心病、脑卒中最主要的危险因素,已成为世界性公共卫生问题。随着我国经济的发展及人们生活水平的日益提高,我国在1958年、1979年、1991年分别进行了全国性的高血压普查,结果表明,我国高血压患病率在持续上升,且上升速度逐年加快。由于文化程度、生活习惯以及信息来源不足的差异也是导致城居民高血压患病率持续上升的重要原因,因此指导城乡居民进行合理的饮食,对预防高血压的发生、发展有着重要的意义。 相似文献

A form of the Semantic Differential, containing 9 concepts related to hypnosis and research, was administered to 96 hypnotically inexperienced male Ss. The Ss were later asked to volunteer for a hypnotic experiment, and the hypnotic susceptibility of all volunteers (N = 51) was then determined. Semantic Differential responses of volunteers and nonvolunteers and of highly susceptible and unhyp-notizable Ss were compared. Differences between groups, in both comparisons, were generally not statistically significant, a finding which suggests that there is no simple relationship between paper-and-pencil measures of attitudes and volunteering for hypnotic experiments or hypnotizability. 相似文献
