RESUMO
Objective: Our aim was to perform a meta-analysis to compare the therapeutic effects of compound Xuanju capsules combined with hormone therapy vs hormone therapy alone in polycystic ovary syndrome (PCOS)-related infertility. Methods: Electronic databases including PubMed, The Cochrane Library, Web of Science, Chinese Biomedical Literature Database (CBM), China National Knowledge Infrastructure (CNKI), Wanfang Data and VIP database were manually searched. The quality of included studies was evaluated based on Cochrane Systematic Review standards, and the valid data were extracted for meta-analysis using RevMan 5.3 software (Cochrane Review). Results: A total of 14 randomized controlled trials (RCTs) including 1249 patients were included in the study. Meta-analysis showed that patients in the compound Xuanju capsule + hormone therapy group had higher estradiol (E2) levels and overall rates of effective treatment than patients in the hormone therapy alone group. Moreover, they exhibited lower levels of luteinizing hormone (LH) and follicle-stimulating hormone (FSH), as well as lower Kupperman scores, than the hormone therapy alone group. Conclusions: The combination of compound Xuanju capsules and hormone therapy is more effective than hormone therapy alone in the treatment of PCOS-related infertility. However, the quality of current studies is low, and high-quality clinical trials are warranted.

To explore the effects of NaF on the growth and cephalotaxine production of Cephalotaxus mannii suspension cells, NaF was added into the C mannii cell suspension cultures at day 15 of culture time. It is documented that NaF suppressed cell growth but enhanced cephalotaxine production. The largest yield obtained of cephalotaxine reached to 9.57mg/L when the cultures were treated with an appropriate dosage of 15mg/L NaF, which was 3.7 times that of the control cultures (2.58mg/L). Additionally, NaF markedly enhanced the activity of glucose 6-phosphate dehydrogenase (G6PDH) and reduced the level of hydrogen peroxide (H2O2) of cells. It was also found that NaF weakened the oxidative damage of cell membrane and led to lower content of malonyl dialdehyde (MDA) in NaF-treated cells compared with the control cells. The MDA content of NaF-treated cells decreased 91% compared to the controls. Although lower membrane lipid peroxidation in NaF-treated cells, its membrane permeability was higher than the control cells and showed a high product secret rate. What is more, NaF boosted the activity of phenylalanine ammonium-lyse (PAL), but did not burst a peak of PAL activity in the time curve of PAL activity. These results indicated NaF acted as an inhibitor of the Enbden Parnas (EMP) pathway, not as an elicitor to promote cephalotaxine production.
