目的:研究天麻素对离体蟾蜍心率和心脏收缩幅度的影响。方法:采用斯氏法制备离体蟾蜍心脏标本,用BL-410生物机能实验系统观察记录心率和心脏的收缩幅度的变化。结果:天麻素浓度为20μg/ml时,可使离体蟾蜍心率增加(P〉0.05),但是不具有统计学意义;而随着浓度从40ug/ml增加至100ug/ml时,心率明显降低(P〈0.05),有统计学意义。天麻素浓度从20ug/nd增加到100ug/ml时,心脏的收缩幅度明显增加(P〈0.05),有显著差异;但是浓度为100ug/ml时,心脏收缩幅度反而降低,与分别加入60ug/ml、80ug/ml天麻素比较有显著差异,P〈0.01;但是与正常组相比不具有统计学意义P〉0.05。结论:在一定浓度范围内天麻素具有降低心率,增加心脏收缩幅度的作用。 相似文献

为了解上海市社区全科医师对基层版《中国高血压防治指南》(简称《指南》)的掌握情况.于2011年3月至2012年12月对上海市徐汇区8个社区卫生服务中心中的260名社区全科医师进行问卷调查.结果,260名社区全科医师回答知道《指南》的有245人(94.2%).对调查问卷中有关高血压流行病学、诊断、治疗、双向转诊及社区管理5个方面的客观问题,260名医师回答正确率分别为49.2%、54.5%、60.6%、56.9%和32.3%,回答总正确率为56.2%.不同年龄、性别、学历和社区的全科医生对《指南》相关知识回答正确率差异均有统计学意义(P值分别为0.000、0.035、0.000和0.000).教学基地组社区在“高血压流行病学知识”、“高血压治疗知识”两方面的回答正确率(分别为58.5%和62.6%)高于非教学基地组社区(分别为39.2%和58.4%),P值分别为0.002和0.040;但两组答题的总体正确率比较差异无统计学意义(P=0.095).提示,目前社区全科医师对《指南》的掌握和运用还存在一定的误区和盲点,应发挥三级医院的作用,在基层医疗机构开展系统、全面、持续、有针对性的培训,提高社区医师对高血压病的诊疗水平. 相似文献

Ethnopharmacological relevance
Huanglian Jiedu decoction (HLJDD) is used traditionally in China for the treatment of diabetes mellitus in clinical practice, which has been proved to be effective. The purpose of this study was to investigate the pharmacokinetic characteristics (especially the area under the curve, AUC) of baicalin and wogonoside in type 2 diabetic rats after oral administration of HLJDD extract and to explore its possible mechanism.Materials and methods
HLJDD extract and Radix scutellariae extract were prepared and the contents of baicalin and wogonoside contained in two extracts were assayed with high performance liquid chromatography (HPLC). Type 2 diabetic rats were induced by high fat diet and intraperitoneal injection of streptozotocin. Pharmacokinetics of baicalin and wogonoside in type 2 diabetic and normal control rats after oral administration of HLJDD extract or Radix scutellariae extract were investigated. Pharmacokinetics of baicalin in type 2 diabetic and normal rats after oral administration of pure baicalin was also investigated.Results
The pharmacokinetic parameters (especially AUCs) of baicalin and wogonoside in type 2 diabetic rats after oral administration of HLJDD extract were remarkably different from those in normal rats. And the alterations of the AUCs of baicalin and wogonoside in type 2 diabetic rats after oral administration of Radix scutellariae extract were similar to those after oral administration of HLJDD extract. Moreover, the increase of the AUC of baicalin in type 2 diabetic rats after oral administration of pure baicalin was similar to that after oral administration of HLJDD extract or Radix scutellariae extract.Conclusion
The pharmacokinetic behaviors of baicalin and wogonoside (especially the systemic exposure [AUCs] of baicalin and wogonoside) were significantly altered in type 2 diabetic rats after orally administrated HLJDD extract. And the increased AUCs of baicalin and wogonoside in type 2 diabetic rats after oral administration of HLJDD extract resulted from neither the effects of other herbs contained in HLJDD nor the effects of other components contained in Radix scutellariae. It might result from the effects of the pathological status of type 2 diabetes mellitus. 相似文献7.

Background
The surgical management of developmental dysplasia of the hip (DDH) in older children has been the subject of controversy. The purpose of this study was to evaluate the outcome in patients with neglected DDH who underwent individual procedures based on using three-dimensional computed tomography.Methods
Forty-seven patients (59 hips) were treated using Pemberton osteotomy or Dega plus Pemberton osteotomy. Subtrochanteric transverse femoral shortening and derotation osteotomy were performed for all patients. The average age at the time of surgery was 10.5 y for group 1 (bilateral dislocation, 24 hips) and 11.2 y for group 2 (unilateral dislocation, 35 hips). Mean follow-up was 5.3 y for group 1 and 5.8 y for group 2.Results
At the end of follow-up, 13 hips (54.2%) were rated excellent, eight hips (33.3%) were good, and three hips (12.5%) were fair in group 1. In group 2, 20 hips (57.1%) were rated excellent, 10 hips (28.6%) were good, and five hips (14.3%) were fair. There were five patients who had a limb length discrepancy of approximately 1.5 cm in group 2. Six hips in group 1 and seven hips in group 2 had osteonecrosis of varying severity.Conclusions
We believe that preoperation three-dimensional computed tomography evaluation, personalized operation plans, and experience with the surgical procedure are the main reasons for the satisfactory therapeutic effects achieved in this study in older children with DDH. 相似文献
