RESUMO
Objective:To study the effects of Zuogui Pills on the expressions of miR-133b-3p and RhoA in osteoclasts of postmenopausal osteoporosis rats; To discuss its potential mechanism.Methods:SD female rats were randomly divided into normal group, model group, sham-operation group, and Zuogui Pills group using a random number table method, with 6 rats in each group. The model group and Zuogui Pills group were treated with oophorectomy to construct a rat model of osteoporosis. Zuogui Pills group was orally administered with Zuogui Pills decoction at a concentration of 10 g/kg for 12 consecutive weeks. Colorimetric method was used to measure the serum calcium and phosphorus levels of rats, and ELISA method was used to detect ALP levels. Bone density meter was used to measure the bone density of the femurs of rats in each group. The osteoclast of each group were cultured, and the expressions of RANKL and RUNX2 protein were detected by Western blot. MiRNA sequencing and differential expression analysis were performed on bone tissues of rats. Osteoclasts were treated with miR-133b-3p mimic and its negative control. The cell proliferation activity of osteoclasts was detected by cell counting kit-8 (CCK-8). The osteoclast differentiation activity was detected by the tartrate-resistant acid phosphatase staining. The dual-luciferase reporter assay was used to detect the relationship between miR-133b-3p and RhoA. The "rescue" experiment of miR-133b-3p mimic and RhoA co-expression were used to study the molecular regulatory mechanism of Zuogui Pills on osteoclast activity.Results:Compared with the model group, the bone mineral density of Zuogui Pills group significantly increased ( P<0.05, P<0.01), the levels of calcium and phosphorus in serum increased, the level of alkaline phosphatase ALP decreased ( P<0.05), the expression of RANKL protein decreased, and the expression of RUNX2 protein increased. Sequencing results showed that rno-miR-133b-3p was down-regulated in osteoclasts of postmenopausa osteoporosis rats treated with Zuogui Pills with the maximum difference ( P<0.01). Q-PCR results showed that the expression of miR-133b-3p in osteoclasts of Zuogui Pills group was significantly lower than that of the model group. The upregulation of miR-133b-3p could significantly promote the cell proliferation and differentiation of osteoclasts. RhoA overexpression could reverse the excessive proliferation and differentiation of osteoclasts caused by miR-133b-3p overexpression. Conclusions:RhoA is the target gene regulated by miR-133b-3p. Zuogui Pills can inhibit the activity of osteoclasts by regulating miR-133b-3p/RhoA axis, relieving the symptoms of osteoporosis.
RESUMO
Objective To analysis the effect of using comprehensive rehabilitation treatment for osteoporotic bulging disc combine diabetes otients.Methods Ninety cases osteoporotic bulging disc combine diabetes patients, who treated in Guanganmen Hospital of Chinese Academy of Traditional Chinese Medicine from January 2011 to January 2011, were randomly divided them into observation group and control group, 45 cases in each group, control group was given conventional treatment, the observation group was given comprehensive rehabilitation treatment, compare visual analogue scale (VAS) score and Oswetry functional disability index (ODI) changes in two groups after treatment, and compared the efficient of treatment.Results VAS scores after treatment for one course and 2 courses in observation group were respectively (2.05± 1.31) and (1.26± 1.03) points,ODI score was respectively (26.37±5.10) and (21.82±4.57) points, VAS score in the control group was (5.85±1.38) and (3.29±1.94) points,ODI score was respectively (37.29±6.32) and (28.33±5.30), all obviously improving than before treatment, but compared with control group, the observation group improved more apparent,the difference between groups was statistically significant(P＜0.05).Treatment effective rate in observation group was 95.56％ (43/45), the control group was 80.00％ (36/45), the difference between groups was statistically significant(x2=5.075 ,P＜0.05).Conclusion Comprehensive rehabilitation therapy applied in treatment for osteoporotic bulging disc combine diabetes patients can obviously improve the patient's pain symptomsand and the lumbar spine, obtain better treatment effect, worthy of clinical popularization and applications.
