OBJECTIVETo investigate the efficacy of Bushen Huoxue Fang (BSHXF, a traditional Chinese medicine formula) for improving recurrent spontaneous abortion (RSA) in mice and the role of tyrosine kinase (JAK2) and transcriptional activator (STAT3) signaling pathway in its therapeutic mechanism.METHODSFemale CBA/J mice were caged with male DBA/2 mice to establish RSA mouse models, which were randomly divided into model group, dydrogesterone group and BSHXF group, with the female mice caged with male BALB/c mice as the control group (n=6). From the first day of pregnancy, the mice were subjected to daily intragastric administration of BSHXF, dydrogesterone, or distilled water (in control and model groups) for 12 days. After the treatments, serum levels of antithrombin III (AT-III), activated protein C (APC), tissue plasminogen activator (t-PA), progesterone, human chorionic gonadotropin (HCG), and estradiol (E2) were detected in each group using ELISA. HE staining was used to observe the morphological changes of the endometrium of the mice. Western blotting was performed to determine the expressions of p-JAK2, p-Stat3 and Bcl-2 in the placenta of the mice.RESULTSCompared with the control mice, the mouse models of RSA showed a significantly increased embryo loss rate with decreased serum levels of AT-III, T-PA, progesterone, APC and HCG, increased placental expressions of p-JAK2, p-STAT3 and Bax, and decreased expression of Bcl-2 (P < 0.05). Treatments with BSHXF and dydrogesterone both increased serum levels of AT-III, t-PA and HCG in the mouse models; Serum APC level was significantly reduced in BSHXF group and serum progesterone level was significantly increased in dydrogesterone group (P < 0.05).CONCLUSIONBSHXF can improve the prethrombotic state and inhibit cell apoptosis by downregulating the JAK2/STAT3 pathway to increase the pregnancy rate in mouse models of RSA.

Objective. This case‐control study was to explore the effect of Bushen Zhuanggu tablet combined with routine regimen on bone mineral density (BMD) improvement, functional recovery, and fracture prevention in postmenopausal osteoporosis (PMOP) patients. Methods. 180 postmenopausal osteoporosis patients were randomly selected from communities A, B, and C cohorts as research subjects from January to May 2021. The study subjects were divided into three groups. The groups were in a 1 : 1 ratio according to the principles of nonrandomised, concurrent controlled trials, and methods. There were 60 participants in each group (group A, group B, and group C). Group A was treated with Bushen Zhuanggu tablet for antiosteoporosis + basic treatment (calcium supplement and vitamin D). Group C was given Bushen Zhuanggu tablet for antiosteoporosis intervention. Group B was given basic treatment (calcium supplement and vitamin D supplementation) as a control group. The follow‐up time was 6 months after treatment. Finally, we compare the differences in calcium and phosphorus metabolism indexes, BMD, bone metabolism indexes, upper and lower limb muscle strength, and quality of life scores. Results. Group A, B, and C’s effective rate was 98.33%, 80.00%, and 93.33%, respectively. The group A’s effective rate was significantly higher than that in group B and C, and the difference was statistically significant (P < 0.05). After 6 months intervention, the levels of serum Ca2+, serum phosphorus (P), serum creatinine (Cr), and parathyroid hormone (PTH) in 3 groups decreased. Ca, P, Scr, and PTH levels in group A were the lowest among study groups, and the difference was statistically significant (P < 0.05). The increase in the BMD of lumbar spine, the left femoral neck, and Ward’s triangle area of the three groups were observed with the highest data in group A. After 6 months of treatment, the levels of serum N‐terminal propeptide of type I procollagen, PINP, and serum osteocalcin (OC) increased, while the levels of β‐cross‐linked C‐terminal telopeptide of type I collagen (β‐CTX) and alkaline phosphatase (ALP) decreased in the three groups. The improvement of all bone metabolic indexes in group A was significantly better than that in B and C groups, and the difference was statistically significant (P < 0.05). The enhanced upper limb muscle strength and the shorter standing‐walking timing test (TUGT) time were observed after 6 months of treatment. The improvement effect of upper and lower limb muscle strength in group A was significantly better than that in B and C groups, and the difference was statistically significant (P < 0.05). There were significant differences in physiological function, life function, general health status, physical pain, mental state, emotional function, vitality, and social function among the three groups after 6 months treatment, and the difference was statistically significant (P < 0.05). The score of quality of life in group A was higher than that in B and C groups, and the difference was statistically significant (P < 0.05). Conclusion. Bushen Zhuanggu tablet combined with conventional therapy is effective in the postmenopausal osteoporosis treatment, which effectively increase the BMD, regulate calcium and phosphorus metabolism, promote the recovery of limb function, prevent the recurrence of fracture, and improve the patients’ quality of life. This treatment scheme is worth popularizing.

OBJECTIVETo investigate the effect on bone marrow stem cell transplantition (BMST) combinated with Bushen fang therapy in mdx mice.METHODSCultured the bone marrow cells of C56BL/6 in vitro and tranplante these cells to mdx mice after irradiation. Bushen fang was used to cure the mdx mice after BMST. The survivel rate, symptom of Graft Versus Host Disease (GVHD) and motor function of model mice following irradiation and transplantation were observed 4 or 8 months after BMST, prepared the freeze-splice of muscles of each group, and made HE staining. The dystrophin (DYS) was detected by SABC immunofluorescene.RESULTSBushen fang could decrease the rate of centrally nucleated fibers (CNF), enhance expressional rate of DYS in different level and relieve the symptom of GVHD in transplanted mice.CONCLUSIONBushen fang can improve the therapeutic efficacy of BMST.
