中医浅析高同型半胱氨酸血症

高同型半胱氨酸血症（Homocysteinemia）是指外周血中经过还原作用后可生成高半胱氨酸（Hcy）的物质的总体含量升高一种病症。本文从中医角度来探讨高同型半胱氨酸血症的病因病机与治疗。认为先天禀赋不足、后天精微物质的缺乏是其主要病因,痰瘀交阻是病机关键,瘀血和痰浊同是病理产物,又都是继发新的病变的致病因素,可导致脏腑功能失调,气血津液运行障碍,同型半胱氨酸（Hcy）在体内蓄积,造成高同型半胱氨酸血症,顾在治疗上据此施以化痰降浊,活血祛瘀之法,临床运用大安丸加减治疗效果较佳。

Women’s ability to self-screen for contraindications to combined oral contraceptive pills in Tanzanian drug shops

Objective

To estimate the accuracy of self-screening for contraindications to combined oral contraceptive pills (COCs) and to estimate the proportion of women with contraindications to hormonal methods among those using drug shops in Tanzania.

Methods

Trained nurses interviewed 1651 women aged 18–39 years who self-screened for contraindications to COCs with the help of a poster at drug shops in Tanzania. Nurse assessment of the women served as the gold standard for comparison with self-assessment. Blood pressure was also measured onsite.

Results

Nurses reported that 437 (26.5%) women were not eligible to use COCs, compared with 485 (29.4%) according to self-report. Overall, 133 (8.1%) women who said that they were eligible were deemed ineligible by nurses. The rate of ineligibility was artificially high owing to participant and nurse assessments that were incorrectly based on adverse effects of pill use and cultural reasons, and because of the sampling procedure, which intercepted women regardless of their reasons for visiting the drug shop. Adjusted rates of ineligibility were 8.6% and 12.7%, respectively, according to nurse and participant assessment. Both nurses and women underestimated the prevalence of hypertension in the present group.

Conclusion

Self-screening among women in rural and peri-urban Tanzania with regard to contraindications to COC use was comparable to assessment by trained nurses.     

Oral contraceptive pills for endometriosis after conservative surgery: a systematic review and meta-analysis

Abstract

To assess the effects of oral contraceptive pills (OCPs) for endometriosis in women after conservative surgery, we performed a search of PubMed, Embase, ISI Web of Science, Cochrane Library, Scidirect, Chinese VIP, CNKI and WANGFANG database. Randomized controlled trials (RCTs) of OCPs in postoperative medical therapy for endometriosis were collected. Articles published as of January 2013 with no language restriction were identified using defined keywords, and 15 studies comprising 1850 patients were included. There was a significantly higher rate of total endometriosis remission [OR?=?2.55, 95% CI (1.68, 3.86), p?<?0.00001] and a lower rate of recurrence [OR?=?0.31, 95% CI (0.22, 0.45), p?<?0.00001] in the OCPs group compared with surgery alone. There appears to be no statistical difference in pregnancy rates between the OCPs group as compared with surgery alone or other hormonal drug treatments in infertility patients. As for the rate of recurrence and complete remission, there were no statistical differences among OCPs and gestrinone, mifepristone or GnRH-a groups. However, OCPs users had less side effects that were more mild as compared with patients using other hormonal treatments.

鹿茸健骨滴丸对骨质疏松症大鼠肾组织TRPV5表达的影响

目的: 通过观察鹿茸健骨滴丸对糖皮质激素性骨质疏松症(GIO)大鼠股骨骨密度(BMD)及肾组织钙转运通路蛋白(TRPV5) mRNA和蛋白表达的影响,探讨GIO的病理机制及鹿茸健骨滴丸的疗效。 方法: 将82只Wistar大鼠随机分为正常对照组(A组)、模型组(B组)、鹿茸健骨滴丸组(C组) 及骨疏康组(D组)。采用后肢肌注地塞米松(2.5 mg·kg^-1,每周2次)造模,造模同时,C,D 组分别按0.88, 2.1 g·kg^-1·d^-1 剂量ig给药,造模及给药9周后,应用XR-26型双能X射线骨密度仪测定BMD,采用实时定量PCR法及Western blot法测定肾组织TRPV5 mRNA和蛋白表达。 结果: 与正常组比较,模型组大鼠BMD明显降低(P<0.01),肾组织TRPV5 mRNA与蛋白表达均明显下降(P<0.01);与模型组比较,鹿茸健骨滴丸组BMD明显升高(P<0.01),TRPV5 mRNA与蛋白表达亦明显上调(P<0.01)。 结论: 地塞米松对肾钙转运过程产生抑制作用,是其诱发GIO的重要病理机制之一,鹿茸健骨滴丸通过上调肾组织TRPV5 mRNA与蛋白表达而促进肾钙重吸收,达到治疗GIO的作用。
