Effectiveness of acupuncture on pregnancy success rates for women undergoing in vitro fertilization: A randomized controlled trial

ObjectiveTo investigate the effect of acupuncture on pregnancy success rates applied before and after embryo transfer (ET) among women undergoing in vitro fertilization (IVF).Materials and methodsIn this randomized controlled trial, 72 infertile women undergoing IVF were randomized to acupuncture (AG; n = 36) and control group (CG; n = 36). Three sessions of acupuncture were applied to AG, the first was one week before ET, the second was 30 min before ET, and the third was 30 min after ET. CG received no acupuncture. The primary outcome was pregnancy success rate (Beta-HCG level, clinical pregnancy, ongoing pregnancy, live birth). Secondary outcome was anxiety level (STAI-1 state anxiety scale). Beta-HCG levels were assessed for conception 12 days after ET. Additionally, STAI-1 state anxiety scale was administered 30 min before and after ET to measure anxiety levels in both groups.ResultsThe mean age was 30.9 ± 3.7 years. Positive Beta HCG was detected in 63.9% (n = 23) of the AG and 33.3% (n = 12) of CG (p = 0.009). Clinical pregnancy, ongoing pregnancy, and live birth rates were higher in AG (p < 0.05). There was no difference between the groups concerning anxiety scores before ET (p > 0.05). The mean STAI-1 score was decreasing from 57.3 ± 9.8 to 28.8 ± 3.3 in AG, while it was decreasing from 57.0 ± 8.0 to 41,1 ± 6,8 in CG after ET (p < 0.000).ConclusionsIt was observed that three sessions of acupuncture before and after ET significantly increased the pregnancy rates in women with unexplained infertility. It was also found that acupuncture significantly reduced anxiety levels that occurred before ET.

含功能性油的水飞蓟宾超饱和自纳米乳的制备与体外评价

目的制备含功能性油的水飞蓟宾超饱和自纳米乳(SLB-S-SNEDDS),并对其进行表征及体外评价研究,以提高难溶性药物水飞蓟宾的生物利用度。方法铁氢化钾还原力与1,1-二苯基-2-苦肼基(DPPH)自由基清除实验筛选功能性油脂;伪三元相图考察乳化剂乳化能力;测定粒径、多分散指数(PDI)、Zeta电位等考察混合油相比例与载药量;相容性与溶出度实验筛选促过饱和物质并考察其质量浓度;从外观、粒径分布、自乳化效率、形态学等方面表征SLB-S-SNEDDS,并进行溶出度、抗氧化能力、细胞毒性等体外评价。结果所得SLB-S-SNEDDS处方为(1)小麦胚芽油/Capryol 90-Cremophor ELP-Transcutol HP与(2)沙棘籽油/Capryol 90-Cremophor ELP-Transcutol HP,1 g基质(包含0.043 g小麦胚芽油或沙棘籽油、0.387 g Capryol 90、0.380 g Cremophor ELP、0.190 g Transcutol HP),水飞蓟宾的添加量为各组分平衡溶解度之和的20%,Soluplus的添加量为上述总质量的0.1%。小麦胚芽油、沙棘籽油体系分别为淡黄色、亮黄色透明状均一液体,2种体系自乳化分散后均呈近球形白色扁平乳滴,粒径约为50 nm,乳化时间均为65 s。与药物原料及SLB-SNEDDS相比,SLB-S-SNEDDS中水飞蓟宾的累积溶出率8h内均维持在85%～110%,表明该体系能够显著提高药物的溶出度。SLB-S-SNEDDS与铁氰化钾反应后的吸光度(A值0.452～0.782,0.488～0.765)以及DPPH自由基清除率(39.09%～96.02%,30.54%～89.20%)均高于相应质量浓度下水飞蓟宾原料的A值与清除率(0.411～0.760,22.89%～63.21%),表明2种处方体系均能提高水飞蓟宾的抗氧化能力。细胞毒性实验结果显示,在5、10μmol/L药物浓度下,水飞蓟宾原料组、水飞蓟宾S-SNEDDS组及其相应的空白S-SNEDDS组细胞生存率均90%,说明SLB-S-SNEDDS及其所用辅料对人克隆结肠腺癌细胞(Caco-2)毒性较小、安全性较好。结论制备的含功能性油SLB-S-SNEDDS在提高水飞蓟宾累积溶出率的同时,增强了其抗氧化能力,为将超饱和自纳米乳(S-SNEDDS)用于改善难溶性药物水溶性及其生物活性提供有益参考。
