Return of fertility following discontinuation of an injectable contraceptive — Norethisterone oenanthate (NET EN) 200mg dose

The return of fertility following discontinuation of norethisterone oenanthate (NET EN) 200 mg injectable contraceptive after use for a minimum period of six months or more was studied in 69 women who discontinued the method for planning pregnancy. Former users of copper intra-uterine device (CuT 200) were enrolled as a control group. Another 161 women who had discontinued NET EN due to other reasons (e.g. amenorrhoea, excessive bleeding or personal reasons) were also studied for return of fertility after ensuring that they were not using any other method of contraception and were exposed to the risk of pregnancy. The subjects from both groups were followed for a period of one year. The cumulative conception rates at one year were 72.5 and 83.6 per 100 subjects for ex-NET EN and ex-CuT 200 users who had discontinued the method for planning pregnancy and this difference was not statistically significant (P > 0.05). The median time for conception for ex-NET EN users was 7.8 months as compared to 3.7 months in ex-CuT 200 users but the cumulative conception rates at the end of one year show that future return of fertility in NET EN users does not appear to be adversely affected.

In 51 subjects who had discontinued NET EN due to amenorrhoea, the return of fertility was predictably slower and less. The return of fertility in subjects who discontinued NET EN for other reasons (e.g. excessive bleeding and other personal reasons) was similar to ex-NET EN and ex-CuT 200 users.

清炎颗粒对肾盂肾炎小鼠外周血IL-8与IL-10的影响

目的：探讨清炎颗粒治疗肾盂肾炎的免疫学机制。方法：采用孙氏方法改进造模,治疗组分别按剂量3.12、6.24、12.48g·kg^-1·d^-1予清炎颗粒,模型组予生理盐水,对照组予至灵胶囊灌胃,喂养至3d、7d、15d、30d、60d取血清,用ELISA法检测其IL-8、IL-10的水平。结果：清炎颗粒能显著降低不同时段血清IL-8的水平、提高不同时段血清IL-10的水平。结论：免疫调控可能是清炎颗粒治疗肾盂肾炎的作用机制之一。     

青霉素配伍利多卡因后的药物动力学研究

本文报道青霉素配伍利多卡因后的药物动力学及生物利用度研究结果,证明利多卡因对青霉素的生物利用度无影响,且可促进青霉素的吸收,为良好的青霉素无痛溶媒,建议推广使用。     

头皮电烧伤骨外露带毛发皮瓣修复

目的：探讨头皮电烧伤骨外露用头皮扩张皮瓣移植修复的临床效果。方法：采用早期扩创,保留部分坏死骨质,用邻近头皮扩张使带毛发的头皮面积扩大后移植覆盖创面,电性失活骨质在血循环良好的皮瓣覆盖下,为周边及基底健康骨质生长起到支架作用,皮瓣扩张到一定面积后移植到裸露骨质上,使其得以修复。结果：在治疗的9例中,除1例皮瓣边缘在1．5cm×1．5cm坏死外,其余皮瓣全部成活,未发生感染坏死,创面均一次性封闭。结论：头皮电烧伤骨外露扩张后皮瓣带毛发修复,可缩短创面愈合时间,外形较好,易掌握,效果较为满意。     

中药内外并用抗尖锐湿疣复发的临床研究

目的：观察中药消疣丸/消疣擦剂内服外用防止尖锐湿疣复发的作用.方法：应用免疫学方法，检测患者治疗前后外周血T淋巴细胞亚群CD3、CD4、CD8的百分率和CD4/CD8的比值.结果：局部消除疣体后中药消疣丸/消疣擦剂内服外用对防止尖锐湿疣复发有显著疗效，痊愈率为99.66%，复发率为3.33%，与对照组相比有显著差异（P〈0.05）.结论：中药内服外用抗尖锐湿疣复发效果好。     

氨气敏电极法快速测定血氨

本文介绍使用氨气敏电极,采用标准曲线法简便、快速、准确测定血氨的方法。取空腹血1ml,用1M HClO_4沉淀蛋白,以0.1M NH_4Cl—0.6MNa_2SO_4作内充液,碱化后的上清液可在2～3min内测试完毕。40例正常成人血氨的测定结果:■=31.4μmol/L N;S=6.4μmol/L N;■±2S(正常值范围)为18.6～44.2μmol/L N。10份血样的平均回收率为100.4％。该法用血少、简便、快速;结果较稳定、准确,适用于临床检验。     

对血脂异常人群实施生活方式干预后的观察

目的：探讨生活方式治疗在血脂异常人群中的作用，观察其效果。方法：100例在体检中发现的血脂异常者，随机分为实验组和对照组，对实验组进行生活方式治疗，对照组未进行生活方式治疗，两组均未使用药物降脂，随访6—9个月，平均7．6个月，复查血脂，以检测血脂结果是否达到目标值进行对比。结果：经统计学处理，两组血脂在达到目标值方面存在显著性差异（p〈0．01）。结论：生活方式治疗对血脂异常人群具有明显的防治作用。
