The activity of free radicals in follicular fluid was related to ovarian responsiveness, in vitro fertilization (IVF), and embryo transfer success rate. However, studies analyzing the relationship between the free radical scavenging capacity and embryo quality of infertile women with polycystic ovarian syndrome (PCOS) were lacking. The aim of this study was to evaluate the relationship between the free radical scavenging window of women with PCOS and their embryo quality. The free radical scavenging capacity of follicular fluid from women with PCOS was determined by a,a-diphenyl-b-picrylhydrazyl (DPPH), 2,2-azinobis (3-ethylbenzthiazoline-6-sulphonic acid) assay, superoxide radical, and reactive oxygen species (ROS) assay. In the DPPH and ROS assays, the follicular fluid from grades I and II embryos was significantly higher than the follicular fluid from grades III and IV embryos. The lower control limit of DPPH radical scavenging capacity and upper control limit of ROS level were 13.2% and 109.0 cps, respectively. The calculated lower control limit and upper control limit were further confirmed in the follicular fluid of embryos of all grades. These cut-off values of free radical scavenging activity of follicular fluid could assist embryologists in choosing the development of embryos in PCOS patients undergoing IVF.

基于过一硫酸盐的非均相催化活化技术在废水处理中越来越受到关注。因此,找到一种可持续、经济、有效的活性材料用于废水处理非常重要。本研究以金属有机框架材料(MOF)-5 为前驱体,通过添加镍离子并随后煅烧制备了一种稳定、可循环利用的材料ZnO@Ni3ZnC0.7,该材料表现出良好的吸附和催化性能。为了研究和优化实际应用条件,选择了罗丹明B(RhB)在水中的降解作为模型过程。研究表明,体系中有机物的去除涉及吸附和降解过程的耦合。基于此,提出了整个去除过程的机理。扫描电子显微镜、红外光谱分析和理论分析的结果证实,范德华力、静电吸引力和氢键影响吸附过程。电子顺磁共振分析、遮蔽实验和电化学测试证实,RhB的降解路径包括自由基和非自由基途径,表面羟基是关键的活性位点。对吸附底物的降解使活性位点得到再生。用简单方法再生的材料在4 个循环测试中对有机化合物保持很高的去除效率。此外,这种材料还可以有效地去除各种有机污染物,并且由于具有磁性,材料易于回收。结果表明,使用具有良好吸附能力的非均相催化材料可能是一种经济有效的策略。

To date, the efficacy of radical surgery (RS) versus conservative surgery (CS) for liver hydatid cysts (LHC) remains controversial. This meta-analysis was conducted to compare the two interventions. PubMed, Embase, and Web of Science were searched from their inceptions until June 2016. Meta-analysis was performed using STATA 12.0 software. We identified 19 eligible studies from 10 countries by retrieval. In total, 1853 LHC patients who received RS were compared with 2274 patients treated by CS. The risk of postoperative overall complication, biliary fistula, and recurrence was significantly lower, and operation time was significantly longer in the RS group. However, no statistically significant differences were found in terms of mortality risk and the duration of hospital stay between RS and CS. No significant publication biases were observed in all the above analyses. In conclusion, RS reduces the rates of postoperative complications and recurrence, whereas no trend toward such a reduction in mortality was observed in LHC patients.
