复方丹参滴丸对不稳定型心绞痛患者血浆内皮素和血小板α-膜颗粒蛋白的影响

目的观察复方丹参滴丸对不稳定型心绞痛患者的临床疗效及血浆内皮素（ET）和血小板α-膜颗粒蛋白（GMP-140）水平的影响。方法168例不稳定型心绞痛患者分为常规治疗组（79例）和复方丹参滴丸组（89例）。所有入选患者均接受硝酸酯类、美托洛尔（或钙拮抗剂）及阿司匹林治疗，复方丹参滴丸组在上述治疗基础上加用复方丹参滴丸10粒，每日3次，连用8周。观察统计两组治疗前1周和治疗结束后1周心绞痛发作次数及自拟的疼痛强度及持续时间记分值，检测治疗前后患者血浆ET和GMP-140水平的变化。结果复方丹参滴丸组和常规治疗组比较，治疗后疼痛发作频率、疼痛强度及持续时间记分均有明显减少，而复方丹参滴丸组的降低程度比常规治疗组明显（P〈0．05）。两组可改善不稳定型心绞痛患者心电图ST段的偏移，而复方丹参滴丸组的疗效比常规治疗组显著（P〈0．05）。两组治疗后血浆ET和GMP-140水平均明显减低，而复方丹参滴丸组的疗效比常规治疗组显著（P〈0．01）。结论复方丹参滴丸治疗不稳定型心绞痛患者疗效明显高于常规治疗，可能与改善血管内皮功能、抑制血小板聚集密切相关。

目的：观察复方丹参滴丸对高粘滞血症血管内皮分泌功能的影响，探索其作用机制。方法：复合因素(高分子右旋糖酐、肾上腺素、牛血清白蛋白)、长时间(112天)造成高粘滞血症慢性模型；一次性静脉注射高分子右旋糖酐。皮下注射(sc)肾上腺素造成急性高粘滞血症模型，分别用复方丹参滴丸进行治疗，观察血管肉皮细胞分泌功能的变化。结果：慢性高粘滞血症模型血浆血栓素B2(TXB2)和内皮素(ET)浓度非常显升高，而6-酮-前列腺素F1x(6-酮)浓度非常显降低；急性高粘滞血症模型血管内皮分泌功能无显变化；长期使用复方丹参滴丸能调整、改善血管内皮分泌功能的异常状态；复方丹参滴丸改善血管内皮分泌功能的即时效应不显。     

Feasibility of administering mifepristone as a once a month contraceptive pill

Many women find the idea of a once-a-month contraceptive pill an attractive concept. Mifepristone has been shown to be effective as a contraceptive if administered in the early luteal phase. We tested the contraceptive efficacy of 200 mg of mifepristone on day luteinizing hormone (LH) + 2 in a group of 32 women who used a fertility monitor to identify the LH surge. We also recruited a control group, comprising 20 women who were trying to conceive. In this group, 12 women conceived during a total of 50 control cycles (probability of pregnancy 0.25-0.32). Women in the treatment group contributed to a total of 178 cycles and there were two pregnancies (probability of pregnancy 0.01). An LH surge was not detected in 34 cycles (19.1%). In 20 cycles (11.2%) this was due to imperfect use while 14 were monitor method failures (7.9%). Treatment with mifepristone in the early luteal phase did not disrupt the cycle length but women reported slight vaginal bleeding in 15% of the cycles. The combination of a home-use fertility monitor with once-a-month administration of mifepristone (especially if mifepristone is administered at the early luteal phase) is an acceptable contraceptive option with minimal side effects. Unfortunately, it is difficult to envisage how an easier way of defining the correct timing, which required less compliance, could be devised.     

补肾活血汤与定坤丹序贯治疗多囊卵巢综合征的临床效果

目的 探讨补肾活血汤与定坤丹序贯治疗多囊卵巢综合征的效果及性激素水平变化。方法 选取2018年12月—2020年2月本院多囊卵巢综合征患者78例,按随机数字表法分为研究组、对照组,各39例,对照组予以炔雌醇环丙孕酮片进行治疗,研究组予以补肾活血汤与定坤丹进行序贯治疗。对比2组疗效、排卵情况及治疗前后性激素水平[黄体生成激素(LH)、卵泡刺激素(FSH)、睾酮(T)]、最大卵泡直径变化,采用t检验和χ2检验等。结果 研究组治疗总有效率为97.44%,高于对照组的79.49%(P=0.029)。治疗后,研究组LH为(7.26±2.08)mIU/L、T为(1.87±0.59)nmol/L,低于对照组的(9.59±2.26)mIU/L、(2.29±0.48)nmol/L(t=4.737、3.449,P<0.001),FSH为(5.87±2.74)IU/L,高于对照组的(4.80±1.86)IU/L(t=2.018,P=0.047)。治疗后,研究组最大卵泡直径(20.66±4.13)mm,长于对照组的(15.62±3.35)mm(t=5.919,P<0.001);研究组排卵率为71.79%,高于对照组的48.72%(χ2=4.336,P=0.037)。结论 补肾活血汤与定坤丹序贯治疗多囊卵巢综合征,可提高疗效,改善性激素分泌情况,促进卵泡发育,提高排卵率。

The public health implications of the 1995 'pill scare'

The warning issued by the UK Committee on Safety Medicines in October 1995, followed by their 'Dear Doctor' letter of October 18, 1995, that oral contraceptive pills containing gestodene or desogestrel were associated with a higher risk of venous thromboembolism has had a negative impact on public heath. A significant number of women either switched brands or ceased contraception altogether following the announcement. National data suggest a strong association between the pill scare and a substantial increase in the number of unintended pregnancies, particularly significant among younger women, with use of oral contraception falling from 40 to 27% of under 16s between 1995-1996 and 1996-1997. The resulting cost of the increase in births and abortions to the National Health Service has been estimated at about Pound Sterling 21 million for maternity care and from Pound Sterling 46 million for abortion provision. The level of risk should, in future, be more carefully assessed and advice more carefully presented in the interests of public health.     

Safety of modern oral contraception: the options for women: lessons to be learned

The relatively short history of hormonal contraception has been marked by a series of 'pill scares', all of which--after creating panic among users--were proven to be unfounded in terms of public health impact. The latest pill scare, provoked by regulatory action in the United Kingdom and the Federal Republic of Germany in response to the publication of a series of articles indicating a doubling of risk of deep venous thrombosis in users of oral contraceptives containing third-generation progestins, seems finally settled: both the British and the German Drug Regulatory Authorities have now reverted their verdict. The damage unfortunately stays: hundreds of thousands of women have been compelled to abandon the pill of their choice, often deciding to drop contraception altogether, thereby exposing themselves to unwanted pregnancy and--in a number of cases--to pregnancy termination. This latest episode should be turned into something positive: we need to learn that, in the case of drugs in widespread use, before restrictive action is taken--and except for very rare and specific instances--the scientific community must carry out an exhaustive debate on the reality and importance of the observed effects. Although the public should, in each instance, be properly informed, it is only after this process has been completed that restrictive action should be taken. It is hoped that, after this last episode, all concerned have learned this simple principle and will accept being guided by it from now on.
