目的 研究血清离子钙(nCa２＋)在肾综合征出血热(HFRS)中的变化规律及在发病中的作用。方法 用离子选择电极法检测了46例HFRS患者不同病期血清nCa２＋含量,并将nCa２＋与血清尿素氮(BUN)、肌酐(Cr)做相关分析。结果 HFRS患者在低血压休克期和多尿期时血清nCa2＋含量降低(P＜0..05),以少尿期最为显著(P＜0..01)。而且随病情加重,结果依次降低,危重型患者整个多尿期也明显降低。血清nCa２＋含量与BUN、Cr呈负相关(P＜0.01)。结论 血清nCa２＋参与发病过程,与病情轻重和肾功状态密切相关。 相似文献

我们在1981年初步观察流行性出血热(EHF)各期血管紧张素Ⅱ(ATⅡ)水平的基础上,于1984年又对肾素—血管紧张素—醛固酮系统(RAAS)各组成分—血管紧张素Ⅰ(ATⅠ)、ATⅡ、醛固酮(ALD)的血浆含量进行了系统观察。54例患者ATⅡ从发热期开始升高,低血压及少尿期达高峰,多尿期后逐渐下降;ATⅠ各期均减低,低血压及少尿期最明显;ALD在低血压及少尿期与ATⅡ相应地增高。以上改变与病情轻重及尿素氮相平行。实验结果进一步证实RAAS与EHF休克及急性肾功能衰竭的发病有重要联系,故早期稳定体液平衡并拮抗RAAS激活及其影响。是EHF治疗的重要关键。 相似文献

Objective To explore the multiple risk factors for family lifestyle of children with congenital heart defects (CHDs) in Shaanxi Province, China. children and their parents. The univariate and multivariable logistic regression models were used to analyze the influence of risk factors related to parents' lifestyle on CHDs. Results Several possible risk factors were found for CHDs, including fever (OR=4.465, P=0.017), pesticides contact (OR=2.234, P=0.083), passive smoking during pregnancy (OR=20.529, P=0.007) and father's smoking (OR=3.342, P=0.005); fever (OR=2.428, P=0.012) and passive smoking during pregnancy (OR=1.201, P=0.037) were also correlated with ventricular sepal defect (VSD). Conclusion Fever, pesticides contact and passive smoking are associated with CHDs during pregnancy. We should focus our attention on health care during pregnancy to avoid the above-mentioned risk factors and call on parents to hold on to a good healthy lifestyle. 相似文献
