This study was aimed to investigate effects of Er-Xian (EX) decoction in follicular granulosa cell apoptosis in chemotherapy-induced premature ovarian failure (POF) of rats. SD rats were randomly divided into the normal group, model group, positive group and EX decoction group. Intraperitoneal injection of cisplatin was used in the establishment of chemotherapy-induced POF rat model. Intragastric administration of corresponding medication was give to each group for four weeks. The general conditions of rats were observed. The serum contents of E2, FSH, LH and Pro were determined. The ovarian tissue morphology was observed. Granulosa cell apoptosis was analyzed by TUNEL. The expressions of BAX, Bcl-2 and VEGF protein were detected by immunohistochemistry. The results showed that in the model group, the body weight decreased with disordered estrous cycle. After treatment, the weight gained, and the estrous cycle recovered. Compared with the normal group, in the model group, E2 decreased, FSH and LH levels increased. There was no significant difference in the content of progesterone among different groups. Detection of TUNEL showed that the positive expression in the model group was increased compared with the normal group (P < 0.05). The positive expression of EX decoction group was reduced compared to the positive group (P < 0.05). Compared with the normal group, the expression of BAX was obviously increased and Bcl-2 was decreased in the model group. After EX decoction treatment, the expression of BAX was decreased and the Bcl-2 was increased compared to the model group. The expression of VEGF protein in the model group was obviously less than that in the normal group. It was concluded that cisplatin can induce follicular granulosa cell apoptosis, and cause premature ovarian function recession. EX decoction can adjust the content of different hormones in serum, alter expression of apoptosis related protein to reduce the damage of cisplatin on ovarian follicular development, in order to promote follicular development, improve and enhance the ovarian function.

Objective: To observe the efficacy of mild moxibustion combined with arthroscopic meniscal repair in the treatment of meniscal injury and to explore its action mechanism. Methods: Ninety-eight patients with meniscal injury were divided into a surgery group and a moxibustion plus surgery group by the random number table method, with 49 cases in each group. Both groups received arthroscopic meniscal repair, and the moxibustion plus surgery group was treated with add-on mild moxibustion. The Lysholm score, visual analog scale (VAS) score, and mobility of the affected knee were measured before and after treatment, and transforming growth factor (TGF)-β1 and platelet-derived growth factor (PDGF) levels were measured in the fluid of the affected knee joint. The healing of the meniscus was recorded at a follow-up visit 3 months after the surgery. Results: After treatment, the Lysholm score increased, the VAS score decreased in both groups, and the intra-group differences in both groups were statistically significant (P<0.05). The Lysholm score was higher in the moxibustion plus surgery group than in the surgery group, and the VAS score was lower in the moxibustion plus surgery group than in the surgery group. The differences between groups in both scores were statistically significant (P<0.05). The mobility of the affected knee joint increased in both groups (P<0.05), and it was greater in the moxibustion plus surgery group than in the surgery group (P<0.05). When compared with pretreatment, the levels of TGF-β1 and PDGF in the fluid of the knee joint increased in both groups (P<0.05), and the levels of TGF-β1 and PDGF in the fluid of the affected knee joint were higher in the moxibustion plus surgery group than in the surgery group (P<0.05). The healing of the meniscus in the moxibustion plus surgery group was significantly better than that in the surgery group at the follow-up visit 3 months after the surgery (P<0.05). Conclusion: The effect of mild moxibustion combined with arthroscopic meniscal repair is better than the surgery alone in improving knee function, relieving pain, increasing mobility of the affected knee, and promoting meniscal healing, which may be related to the up-regulation of TGF-β1 and PDGF levels in the fluid of knee joint.
