The six phenolic constituents are water-soluble components extracted from the Chinese medical herb danshen, the dried roots of Salvia miltiorrhiza Bunge (Labiatae). An liquid chromatography/tandem mass spectrometry (LC/MS/MS)-based method has been developed for the simultaneous quantification of six phenolic constituents of danshen (magnesium lithospermate B (MLB), rosmarinic acid (RA) and lithospermic acid (LA), caffeic acid (CAA), protocatechuic aldehyde (3,4-dihydroxybenzaldehyde, Pal), 3,4-dihydroxyphenyllactic acid (danshensu)) in human serum with chloramphenicol as internal standard. The serum samples were treated by special liquid-liquid extraction, and the analytes were determined using electrospray negative ionization mass spectrometry in the multiple reaction monitoring (MRM) mode, with sufficient sensitivity to allow analysis of human serum samples generated following administration of a clinically relevant dose. Good linearity over the range 8-2048 ng/mL for six phenolic constituents was observed. The intra- and inter-day precisions (CV) of analysis were <13%, and the accuracy ranged from 88 to 116%. This quantitation method was successfully applied to a pharmacokinetic study of i.v. drip infusion of Danshen injection fluid in human.  相似文献

Hormonal variation over the menstrual cycle alters women's preferences for phenotypic indicators of men's genetic or parental quality. Hormonal contraceptives suppress these shifts, inducing different mate preference patterns among users and non-users. This raises the possibility that women using oral contraception (OC) choose different partners than they would do otherwise but, to date, we know neither whether these laboratory-measured effects are sufficient to exert real-world consequences, nor what these consequences would be. Here, we test for differences in relationship quality and survival between women who were using or not using OC when they chose the partner who fathered their first child. Women who used OC scored lower on measures of sexual satisfaction and partner attraction, experienced increasing sexual dissatisfaction during the relationship, and were more likely to be the one to initiate an eventual separation if it occurred. However, the same women were more satisfied with their partner's paternal provision, and thus had longer relationships and were less likely to separate. These effects are congruent with evolutionary predictions based on cyclical preference shifts. Our results demonstrate that widespread use of hormonal contraception may contribute to relationship outcome, with implications for human reproductive behaviour, family cohesion and quality of life.  相似文献

目的:观察滋肾骨康丸治疗骨质疏松症的临床疗效,并对该药的作用机理进行探讨。方法:将60例病人随机分为治疗组(滋肾骨康丸组)及对照组(西药组),根据2组骨密度、骨痛、中医证候结果及临床总体疗效为指标进行比较。结果:治疗组治疗后总有效率为95.8%,对照组治疗后总有效率为75.3%,差异有统计学意义(P〈0.01);2组治疗前后骨密度无显著性差异(P〉0.05);治疗组治疗后骨痛有效率为92.5%。优于对照组的7313%(P〈0.05);治疗后治疗组中医证候有效率为100%,明显优于对照组的53.3%(P〈0.01)。结论:滋肾骨康丸能显著改善骨痛、肾虚证候,总体改善临床症状,具有较好的治疗作用,值得进一步推广。  相似文献

Pharmacists who refuse to provide certain services or treatment for reasons of conscience have been criticized for failing to fulfil their professional obligations. Currently, individual pharmacists in Great Britain can withhold services or treatment for moral or religious reasons, provided they refer the patient to an alternative source. The most high‐profile cases have concerned the refusal to supply emergency hormonal contraception, which will serve as an example in this article. I propose that the pharmacy profession's policy on conscientious objections should be altered slightly. Building on the work of Brock and Wicclair, I argue that conscientious refusals should be acceptable provided that the patient is informed of the service, the patient is redirected to an alternative source, the refusal does not cause an unreasonable burden to the patient, and the reasons for the refusal are based on the core values of the profession. Finally, I argue that a principled categorical refusal by an individual pharmacist is not morally permissible. I claim that, contrary to current practice, a pharmacist cannot legitimately claim universal exemption from providing a standard service, even if that service is available elsewhere.  相似文献

目的:探讨复方丹参滴丸联合阿司匹林治疗冠心病患者的疗效及其对血脂水平的影响。方法:选取2015年1月至2016年1月我院收治的冠心病患者86例,按照随机数字表法将其分为对照组和实验组,各43例,两组均给予常规治疗,对照组在常规治疗基础上联用阿司匹林,实验组在常规治疗基础上联用阿司匹林和复方丹参滴丸。治疗8周后,对比两组患者临床疗效、甘油三酯(TG)、总胆固醇(TC)、低密度脂蛋白胆固醇(LDL-C)、高密度脂蛋白胆固醇(HDL-C)水平;并对比两组患者的不良反应发生情况。结果:实验组总有效率为86.05%,显著高于对照组的37.21%(P0.05);治疗8周后,实验组TC、TG以及LDL-C较治疗前下降,HDL-C较治疗前升高,差异均有统计学意义(P0.05);治疗8周后,实验组患者血脂TC、TG、LHL均较对照组降低,HDL较对照组升高(P0.05)。治疗期间,实验组不良反应发生率为4.65%,对照组为6.98%,两组患者不良反应发生率无统计学差异(P0.05)。结论:冠心病患者采用复方丹参滴丸联合阿司匹林治疗具有较好的疗效,并能有效改善患者血脂水平,且安全性较高,具备临床推广价值。  相似文献

目的:探讨复方丹参滴丸联合阿司匹林对冠心病(CHD)患者血小板聚集功能及血脂水平的影响。方法:选取2011年10月到2016年12月在我院接受治疗的CHD患者320例作为本次研究对象,采用乱数表法将所有患者分为对照组和观察组各160例,两组患者均采用扩冠、抗凝和降压药物等常规内科治疗,在此基础上对照组给予阿司匹林治疗,观察组给予复方丹参滴丸联合阿司匹林治疗,两组均治疗6个月。对比两组临床疗效、甘油三酯(TG)、总胆固醇(TC)、低密度脂蛋白(LDL)及高密度脂蛋白(HDL)、血栓素B2(TXB2)水平,记录血小板最大聚集率(PAGM)及不良事件发生率。结果:治疗后观察组的总有效率为93.13%,显著高于对照组的68.75%(P0.05)。治疗6个月后观察组HDL水平高于治疗前和对照组,LDL、TC、TG水平低于治疗前和对照组(P0.05)。治疗6个月后两组患者PAGM、TXB2水平均有明显下降,且观察组PAGM、TXB2水平低于对照组(P0.05)。观察组不良事件发生率为2.50%,显著低于对照组的18.13%(P0.05)。结论:复方丹参滴丸与阿司匹林联合治疗CHD临床疗效较好,可以有效抑制血小板凝聚,调节血脂,降低不良事件发生率,值得在临床上推广。  相似文献
