女性尿失禁是女性常见病,目前据全球统计,患病率接近50%,严重尿失禁约为7%,其中约一半为压力性尿失禁(Stress Urinary Incontinence.SUI),我国的患病率与此基本相当。压力性尿失禁患病率高而就诊率却很低,朱兰等的调查显示北京地区成年女性的发病率达38.5%,孙万卉等对北京密云农村地区的调查研究表明老年女性SUI的发病率高达44.9%,国外SUI就诊率为15.0~39.7%,北京地区成年女性的就诊率为7.4%。  相似文献

目的探讨女性抑郁症与代谢综合征的相关性。方法入组90例女性单相抑郁症患者和148例正常女性对照,检测两组人群代谢综合征的各项指标。结果女性抑郁症患者组的代谢综合征患病率与对照组比较,存在显著性差异,抑郁症与代谢综合征存在显著相关性(P<0.01);患者组和对照组各项代谢综合征指标比较,两组身体质量指数、血压无显著性差异(P均>0.05)。患者组的空腹血糖和三酰甘油高于对照组,高密度脂蛋白低于对照组,存在统计学差异(P<0.05或0.01)。结论女性抑郁症与代谢综合征存在关联性。抑郁症的早期治疗对患者身体代谢状况十分重要。另一方面,需要对抑郁症患者的健康状况进行监测。  相似文献

在我地区医院门诊尿常规检查中,经常出现成年女性的小便外观是呈黄色清亮的,可是经过尿常规分析仪检查,小便中有隐血和蛋白出现,显微镜下观察尿沉渣却又未见到红细肥、白细胞、管型及其他异常,我们在排除了其他可引起尿隐血和蛋白出现假阳性的情况后?发现这些病人有一个共同点:她们全是因为腰酸背疼,小便不畅来就诊,问诊中她们的月经期都才结束二到三天。所以我们收集了518例月经才结束二到三天的成年女性病人的小便进行常规分析,现将其报告如下:  相似文献

胃畸胎瘤是一种很罕见的胃部病变,在畸胎瘤中所占比例不足1%,一般好发于男性婴幼儿,特别是出生3个月内的发病占绝大多数。国内1996~2002年间共报告36例,其中除3例成年人(男2例,女1例),7例幼儿外,均发生于新生儿。而自1922年Eusterman首次报告1例31岁男性患者以来,目前胃畸胎瘤正规系统报告尚不足千例。该病以腹胀、腹部肿块为主要临床表现,无特异性,易误诊。因本病好发于出生3个月内的男婴,而成年女性则极为罕见,现报道1例。  相似文献

<正>药物代谢是指药物在体内经历的化学结构的变化过程, 也称为生物转化。药物在体内的代谢大多是酶系统催化反应。药物通过代谢起到解毒作用,但也常常会出现代谢产物毒性更强;有的药物本身没有活性,但进入体内后,代谢产物具有活性。因此药物代谢研究非常重要。  相似文献

Summary Diazepam was metabolized by human foetal liver microsomes to N-desmethyldiazepam and N-methyloxazepam as early as the 13th week of gestation. The metabolic activity was lower than that of microsomes from adult human liver. Diazepam was shown mainly to be hydroxylated to N-methyloxazepam at substrate concentrations higher than 0.1 mM. Diazepam levels above 1.0 mM were inhibitory to the overall metabolic reaction. SKF 525-A inhibited diazepam metabolism by foetal liver microsomes at a concentration of 0.1 mM. The addition of diazepam to foetal and adult human liver microsomes resulted in a type II spectral change. Its inhibition by carbon monoxide indicated that biotransformation of diazepam was performed by the cytochrome P-450-linked mono-oxygenase system.  相似文献

Aging involves progressive impairments in the functional reserve of multiple organs, which might also affect drug metabolism and pharmacokinetics. In addition, the elderly population will develop multiple diseases and, consequently, often has to take several drugs. As the hepatic first-pass effect of highly cleared drugs could be reduced (due to decreases in liver mass and perfusion), the bioavailability of some drugs can be increased in the elderly. Significant changes in body composition occur with advancing age. Lipophilic drugs may have an increased volume of distribution (Vd) with a prolonged half-life, and water-soluble drugs tend to have a smaller Vd. In the elderly, hepatic drug clearance of some drugs can be reduced by up to 30% and CYP-mediated phase I reactions are more likely to be impaired than phase II metabolism, which is relatively preserved in the elderly. Concerning the most important CYP3A4 studies with human liver microsomes and clinical studies with the validated probe, midazolam, it is indicated that there are no significant differences in CYP3A4 activity between young and old populations. Finally, renal excretion is decreased (up to 50%) in about two thirds of elderly subjects, but confounding factors such as hypertension and coronary heart disease account also for a decline in kidney function. In conclusion, age-related physiological and pharmacokinetic changes as well as the presence of comorbidity and polypharmacy will complicate drug therapy in the elderly.  相似文献

The low turnover of caffeine in vitro by human liver microsomes makes the study of the metabolic pathways of this compound difficult. Analytical methods with high sensitivity and specificity are needed for the detection of its metabolic products. A method based on the on-line radiometric determination of [8C-3H]caffeine and its principal metabolite (paraxanthine) in man has been developed using reversed-phase high-performance liquid chromatography. The method has been successfully employed in preliminary studies of the kinetics of this reaction.  相似文献

Summary The glucuronyltransferase activity towards morphine was measured in microsomes isolated from liver specimens obtained from human fetuses and cancer patients. All the fetal livers investigated had measurable UDP-glucuronyltransferase activity towards morphine. There was no correlation between the gestational age (15 to 27 weeks) and the glucuronidation rate. The mean value of the enzymatic activities was higher in fetal livers obtained by hysterotomy (0.20 nmoles×min−1×mg−1) than in livers obtained after induced abortion (0.11 nmoles×min−1×mg−1). The average rate of glucuronidation in microsomes from adult liver (mean 1.15 nmoles×mint-1×mg−1) was 6 to 10 times higher than in the fetal liver microsomes. Together with previous investigations on human adult and fetal liver glucuronidation, the present results support the theory of heterogeneity of human UDP-glucuronyltransferase.  相似文献

Summary This study has examined the contribution of decrease in liver size to the decline in drug metabolising capacity which occurs with ageing. Liver volume and antipyrine kinetics were measured in two groups of healthy individuals aged 20 to 29 years and 75 to 86 years and in a group of hospitalised patients aged 70 to 89 years. Liver volume was reduced in both groups of elderly people compared to the young group. Antipyrine plasma half-life was prolonged and antipyrine clearance was reduced in the group of elderly normal individuals. In this group the index — antipyrine clearance per unit liver volume — was also reduced in comparison to that of the young group. Measurements of antipyrine elimination in the hospitalised elderly group did not differ significantly from those in the young group. It is concluded that both decreased liver mass and decreased hepatic enzyme activity contribute to the impairment of drug oxidation which occurs in the elderly and which may warrant a reduction in dosage of some drugs. However, differences have been demonstrated between groups of elderly people suggesting that under certain circumstances standard doses of such drugs may be normally tolerated.  相似文献
