摘要: Objective To investigate the therapeutic effect of salvia miltiorrhiza polyphenolic acid on immune infertility rats and its effect on hypothalamus-pituitary-ovarian axis (HPOA). Methods Fifty non-pregnant female SD rats were selected. A rat model of immune infertility with anti-sperm antibody (+) was established by human semen injection immunization. The model rats were divided into the model group (n=9), the prednisone group (n=10), the alvia miltiorrhiza polyphenolic acid low dose group (n=9), the salvia miltiorrhiza polyphenolic acid medium dose group (n=10) and the salvia miltiorrhiza polyphenolic acid high dose group (n=10) by random array table method. Another 10 non-pregnant female rats were selected as the normal control group. The prednisone group was given 5 mg/kg prednisone by intraperitoneal injection, and the salvia miltiorrhiza polyphenolic acid low, medium and high dose groups were given 10, 20 and 40 mg/kg salvia miltiorrhiza polyphenolic acid by intraperitoneal injection. The normal control group and model group were given the same amount of normal saline, once a day for 14 days. The female rats and normal male rats in each group were caged in a ratio of 3∶1 for 2 weeks, and the pregnancy rate of rats in each group was observed. The serum levels of gonadotropin-releasing hormone (GnRH), follicle-stimulating hormone (FSH), luteinizing hormone (LH) and estradiol (E2) were determined by radioimmunoassay. Hematoxylin-eosin (HE) staining was used to observe the pathological changes of rat ovarian tissue. Real-time quantitative reverse transcription polymerase chain reaction (qPCR) was used to detect rat ovarian follicle-stimulating hormone receptor (FSHR), luteinizing hormone receptor (LHR) and estrogen receptor alpha (ERα) messenger ribonucleic acid (mRNA) expression. Western blotting (WB) was used to detect rat ovarian FSHR, LHR and ERα protein expressions. Results Compared with the normal control group, the conception rate and the serum levels of GnRH, FSH, LH and E2 were decreased in the model group (P<0.05), the corpus luteum and mature follicles in the ovary were significantly reduced, the number of granulosa cell layers was reduced, and there were more cystic follicles, and the mRNA and protein expressions of FSHR, LHR and ERα were decreased (P<0.05). Compared with the model group, the conception rate and the serum levels of GnRH, FSH, LH, and E2 were increased in the prednisone group and the salvia miltiorrhiza polyphenolic acid medium and high dose groups (P<0.05), the number of cystic follicles was significantly decreased, the number of granulosa cell layers was increased, and mature follicles and corpus luteum were formed. The mRNA and protein expressions of FSHR, LHR and ERα were increased (P<0.05). Conclusion Salvia miltiorrhiza polyphenolic acid can promote follicle maturation by regulating HPOA in the treatment of immune infertility.
