[Clinical efficacy of Bushen Huoxue Culuan Formula in treatment of infertility caused by diminished ovarian reserve due to kidney deficiency and blood stasis].

To study the clinical efficacy and safety of Bushen Huoxue Culuan Formula in treating infertility caused by diminished ovarian reserve(DOR) with kidney deficiency and blood stasis. A total of 100 DOR patients treated at Xiyuan Hospital, Acupuncture Hospital and Clinic of China Academy of Chinese Medical Sciences from 2017 to 2020 in line with the inclusion criteria were selected and randomly divided into experimental group and control group at the ratio of 1∶1. The experimental group was treated with Bushen Huoxue Culuan Formular, while the control group was treated with Climen and Clomiphene for 3 menstrual cycles. The ovulation rate, pregnancy rate, pregnancy success rate, serum hormone levels, and traditional Chinese medicine(TCM) symptom scores were observed in the 2 groups. The total effective rate was 92.00% in the experimental group and 72.00% in the control group, with a statistical difference between the two groups(P<0.01); the experimental group was superior to the control group in reducing FSH level, increasing AMH level, improving TCM symptoms, increasing pregnancy rate and pregnancy success rate, with a significant difference(P<0.05). There was no abnormal safety indicator and adverse reaction. Bushen Huoxue Culuan Formular is effective in treating infertility caused by DOR due to kidney deficiency and blood stasis, with a safety and reliability.

Curcumin pretreatment and post-treatment both improve the antioxidative ability of neurons with oxygen-glucose deprivation.

Recent studies have shown that induced expression of endogenous antioxidative enzymes thr-ough activation of the antioxidant response element/nuclear factor erythroid 2-related factor 2 (Nrf2) pathway may be a neuroprotective strategy. In this study, rat cerebral cortical neurons cultured in vitro were pretreated with 10 µM curcumin or post-treated with 5 µM curcumin, respectively before or after being subjected to oxygen-glucose deprivation and reoxygenation for 24 hours. Both pretreatment and post-treatment resulted in a significant decrease of cell injury as indicated by propidium iodide/Hoechst 33258 staining, a prominent increase of Nrf2 protein expression as indicated by western blot analysis, and a remarkable increase of protein expression and enzyme activity in whole cell lysates of thioredoxin before ischemia, after ischemia, and after reoxygenation. In addition, post-treatment with curcumin inhibited early DNA/RNA oxidation as indicated by immunocytochemistry and increased nuclear Nrf2 protein by inducing nuclear accumulation of Nrf2. These findings suggest that curcumin activates the expression of thioredoxin, an antioxidant protein in the Nrf2 pathway, and protects neurons from death caused by oxygen-glucose deprivation in an in vitro model of ischemia/reperfusion. We speculate that pharmacologic stimulation of antioxidant gene expression may be a promising approach to neuroprotection after cerebral ischemia.
