雷公藤多苷联合孕三烯酮对子宫内膜异位症卵巢功能及血清IL-6，TNF-α，hs-CRP，VEGF及APN的影响

目的:研究雷公藤多苷联合孕三烯酮对子宫内膜异位症卵巢功能及血清白细胞介素-6(IL-6)、肿瘤坏死因子-α(TNF)、超敏C反应蛋白(hs-CRP)、血管内皮生长因子(VEGF)、脂联素APN水平的影响。方法:选取2014年7月至2015年7月我院接诊的子宫内膜异位症患者80例并随机分为两组。对照组采用孕三烯酮进行治疗,观察组采用雷公藤多苷联合孕三烯酮进行治疗,观察两组患者治疗前后血清IL-6、TNF-α、hs-CRP、VEGF、APN、E2、FSH水平、TDS评分的变化并评价治疗疗效。结果:治疗后,观察组血清IL-6、TNF-α、hs-CRP、VEGF、E2、FSH水平及TDS评分均明显低于对照组(P0.05),血清APN水平及总有效率均明显高于对照组(P0.05)。结论:雷公藤多苷联合孕三烯酮能够有效改善子宫内膜异位症患者的卵巢功能,可能与其调节血清IL-6、TNF-α、hs-CRP、VEGF和APN水平有关。     

Determination of gestrinone in human serum by liquid chromatography–electrospray tandem mass spectrometry

A rapid, sensitive and specific high-performance liquid chromatography–electrospray tandem mass spectrometric method has been developed for the determination of gestrinone (R 2323) in human serum using mifepristone (RU 486) as an internal standard. R 2323 was extracted from human serum by an ether extraction procedure. Multiple reaction monitoring was used to detect R 2323 and RU 486. The calibration curve was linear over the range of 3.5–177 ng/ml (r²≥0.99) with the limitation of detection of 0.8 ng/ml. The intra-day precision and accuracy, expressed as C.V. and RE, ranged from 2.3–13.7 to −4.8–3.0%. The inter-day precision and accuracy ranged from 5.5–14.8 to −6.7–3.1%. The mean recovery was 91.0% for R 2323, and 90.6% for the internal standard. The method was successfully applied to the pharmacokinetic study of R 2323.
