Abstract
BACKGROUND Acupuncture is a widely practiced, convenient, and safe treatment modality within complementary and integrative medicine. Increasing studies have revealed the efficacy of acupuncture for the treatment of osteoporosis in both human and non-human subjects. The aim of the present study was to assess the improvement of osteoporosis after overall adjustment acupuncture (OA) as well as its endocrine-modulating effect in an ovariectomized rat model. METHODS In total, 32 female Sprague-Dawley (SD) rats were randomly divided into the sham, model, ovariectomy+estrogen (OVX+E), and OVX+OA (OVX+A) groups with eight rats in each group. The postmenopausal osteoporosis (PMOP) rat model was induced by bilateral ovariectomy. At 12 weeks after surgery, rats in the OVX+E group received estradiol (0.2 mg/kg/i.g./qod) for 12 weeks, and rats in the OVX+A group were treated with acupuncture at Zusanli (ST36), Shenshu (BL23), and Dazhu (BL11) points (qod) for 12 weeks. At the end of the treatment, all rats were sacrificed, and the body weight, uterus index, bone mineral density (BMD), bone mineral content (BMC), bone trabeculae structural parameters, femoral biomechanical properties, femoral histomorphology, and several hormone levels were examined. RESULTS In OVX rats, OA abrogated the body weight gain and improved osteoporosis in terms of BMD, BMC, bone trabeculae structural parameters, bone strength, and bone tissue histomorphology. Moreover, OA modulated the serum levels of estradiol, corticotropin releasing hormone (CRH), adrenocorticotropic hormone (ACTH), and corticosterone (CORT). CONCLUSIONS OA improves osteoporosis and exerts an endocrine-modulating effect in ovariectomized rats.

Abstract
Objectives: By observing the effect of acupoint catgut embedding on the intestinal flora of ovariectomized osteoporotic rats, the correlation between the regulation of intestinal flora and the prevention and treatment of osteoporosis was discussed preliminarily. Methods:
By observing the effect of acupoint catgut embedding on the intestinal flora of ovariectomized osteoporotic rats, the correlation between the regulation of intestinal flora and the prevention and treatment of osteoporosis was discussed preliminarily. Result: Compared with Group A and
Group B, bone mineral density (BMD) of femur and tibia in Group C decreased significantly (p<0.05), indicating successful modeling. Compared with Group C, BMD of femur and tibia in Group D was significantly increased (p<0.05). Compared with Group A and Group B, content of serum estrogens,
calcium, and PTHrP in Group C were significantly decreased (p<0.05 or p<0.01). Content of serum estrogen, calcium, and PTHrP in Group D were significantly higher than those in Group C (p<0.05 or p<0.01). Compared with Group A and Group B, the abundance of mollicutes, actinobacteria,
acidobacteria, chloroflexi and fusobacteria in group C was significantly increased. The abundance of probiotics in Group D such as lactobacillales, (lactobacillaceae, lactobacillus), bacillales, and streptococcus was significantly higher than that in Group C (p<0.05). The content of SCFAs
such as acetic acid, butyric acid, iso-valeric acid, valeric acid and caproic acid in Group D were significantly higher than those in Group C, with statistical significance (p<0.05). Conclusions: Acupoint catgut embedding can effectively improve BMD, increase content of estrogen,
calcium, PTHrP and SCFAs. Furthermore, embedding can also improve the abundance of probiotics and reduce the abundance of pathogenic bacteria. The changes of intestinal flora were correlated with the changes of estrogen and calcium, which may be one of the mechanisms of acupoint catgut embedding
in the prevention and treatment of osteoporosis.
