简介：AbstractObjective:Mifepristone (RU486), one of the most common medications for artificial abortion, attenuates the immunoregulatory effects of progesterone. However, the specific immune regulatory mechanism of RU486 in abortion remains unknown. We intended to investigate the immunomodulatory effects of RU486 on abortion.Methods:Sixty female mice were divided into the control group (0 mg RU486) and RU486 group (2 mg/kg RU486). The uterus, peripheral blood, and spleen were obtained for isolation of specific cell types. The population and phenotype of immune cells in the decidua, peripheral blood, and spleen were analyzed using flow cytometry. Statistical differences between groups were determined using two-tailed t-test. For all statistical tests, P < 0.05 was considered statistically significant.Results:RU486 effectively induced abortion in pregnant mice, with a significantly higher number of decidual macrophages (dMφ) (control group = 25.55% ± 2.467%, RU486 group = 19.41% ± 1.423%; P < 0.05), especially the major histocompatibility complex IIhigh subset. No difference in Mφ number was observed in the spleen or peripheral blood. Moreover, the dMφ from mice with RU486-induced abortion displayed a remarkable activated phenotype, with increased expressions of inducible nitric oxide synthase, tumor necrosis factor-α, and interleukin (IL)-12 but decreased expressions of arginase-1 and IL-10. We also found elevated levels of decidual CD4+ T-cells in the RU486 group that exhibited a higher level of the proinflammatory cytokine interferon-γ and a lower level of the anti-inflammatory cytokines, IL-4 and IL-10.Conclusions:We report a new mechanism of RU486-induced abortion via the regulation of innate cell Mφ activation and the adaptive response of CD4+ T-cells present in the decidua but not the periphery.

简介：摘要目的探讨1010例妇科门诊患者阴道分泌物检查结果分析。方法回顾性分析2017年1月~2017年12月我院妇科1010例门诊患者的阴道分泌物检查结果。结果在妇科门诊患者阴道分泌物检查的1010例患者中，阴道清洁度Ⅰ度患者有9例，检出率为0.79%；阴道清洁度Ⅱ度患者有33例，检出率为2.77%；阴道清洁度Ⅲ度患者有165例，检出率为14.65%；阴道清洁度Ⅳ度患者有803例，检出率为21.39%。组间比较差异有统计学意义（P＜0.05）。结论阴道分泌物检查可作为门诊妇科常规诊疗手段的首选方法，能及时发现妇女的身体情况，在临床初筛妇科感染性疾病、临床用药指导方面具有较高的临床价值。

简介：借助高效液相色谱仪对注射用布比卡因凝胶中抗氧剂1010和抗氧剂1076的含量进行测定。结果表明,新方法检测抗氧剂1010和抗氧剂1076分别在1.00~40.0μg/mL和2.04~81.6μg/mL范围内线性关系良好,相关系数都为0.9999,抗氧剂1010和抗氧剂1076在注射用布比卡因凝胶中平均加标回收率为90.4%(RSD=4.76%)和86.4%(RSD=3.95%),该方法灵敏快速,操作简便,重复性好,可用于检测包装材料中抗氧剂1010和抗氧剂1076在注射用布比卡因凝胶中的迁移情况。

简介：摘要本研究采用双盲法随机分组，应用米非司酮和安慰剂进行药物临床试验。通过给予皮下埋植阴道异常出血患者口服米非司酮（RU486）进行干预，观察对阴道异常出血的效果。通过观察研究组的出血/滴血天数、出血/滴血平均时间均短于对照组。提示每月一次50mg米非司酮口服对皮下埋植避孕剂后阴道异常出血有一定疗效，且不影响皮下埋植避孕剂的避孕效果。

简介：目的了解米非司酮及米索对人早孕蜕膜雌激素受体（ER）、孕激素受体（PR）的表达及血清内分泌水平的影响。方法取正常早孕、服用米非司酮及服米非司酮配伍米索后各20例的蜕膜,应用单克隆抗体链霉素亲生物蛋白——过氧化酶（SP）免疫组织化学方法测定ER、PR的表达及血清激素水平的变化。结果米非司酮配伍米索使蜕膜组织中ER、PR表达下调,正常早孕组、服米非司酮组及服米非司酮配伍米索组之间差异有显著性。血清雌二醇（E2）、睾酮（T）、泌乳素（PRL）含量上升,孕酮（P）下降;而对FSH、hCG的含量无明显影响。结论大剂量RU486能竞争地结合蜕膜组织孕激素受体,使早孕期高浓度的内源性孕酮与其受体的正常结合受到干扰,从而达到抗早孕的目的。

简介：摘要：本研究采用高效液相色谱检测XXX注射液中包装材料浸出物抗氧剂1010和3-（3,5-二叔丁基-4-羟基苯基）丙酸。用Poroshell 120 EC-C18为固定相，以乙腈-水（含0.1%冰乙酸）为流动相的梯度洗脱，以280nm的波长，300nm的参比波长的二极管阵列检测器进行检测。结果表明，抗氧剂1010，3-（3,5-二叔丁基-4-羟基苯基）丙酸分别在1.835～45.001μg/ml和0.601～7.700μg/ml范围内浓度与峰面积呈现良好的线性关系，在低、中、高三个加标浓度下的回收率分别为100.90%～106.57%和99.64～107.62%，精密度RSD（n=6）分别为0.34%和0.96%。在XXX注射液药包材中抗氧剂1010和3-（3,5-二叔丁基-4-羟基苯基）丙酸的检测限分别为0.915μg/ml、0.302μg/ml。
