目的 丹酚酸B是传统中药丹参的重要生物活性组分,临床应用广泛。新近发现,丹酚酸B具有防治骨质疏松的作用。本研究拟在前期工作基础上,系统地研究丹酚酸B对去卵巢骨质疏松小鼠的作用,探讨其对小鼠间充质干细胞（MSCs）成骨分化的影响。方法 将18只8周龄SPF级别的C57雌性小鼠分为假手术组、骨质疏松组、丹酚酸B治疗组。骨质疏松组和丹酚酸B治疗组行双侧卵巢摘除术。而假手术组则保持正常的卵巢结构,同时去除局部的脂肪。3组均于术后3日内给予抗生素进行抗感染治疗。4周内,丹酚酸B治疗组给予丹酚酸B 2.5 mg/kg腹腔注射,连续12周,2天1次,其余2组在相同的时间内给予等量生理盐水。16周后,在麻醉状态下将所有小鼠处死。应用MicroCT测量了小鼠右后股骨的骨密度。采用qRT-PCR技术,分析小鼠左后股骨骨髓MSCs中Runx2和Osterix的表达。将小鼠右后股骨进行液氮研磨处理,提取蛋白质,用WB法测定OPG和RANKL的含量。结果 骨质疏松组小鼠股骨骨密度比假手术组低（P<0.05）,丹酚酸B治疗组小鼠股骨骨密度比骨质疏松组高,但差异无显著性意义（P<0.05）。骨质疏松组小鼠Runx2和Osterix水平低于假手术组（P<0.05）,丹酚酸B治疗组小鼠Runx2和Osterix水平比骨质疏松组高（P<0.05）。骨质疏松组小鼠OPG和RANKL蛋白水平低于假手术组（P<0.05）,丹酚酸B组小鼠OPG和RANKL蛋白水平比骨质疏松组高（P<0.05）。结论 绝经后骨质疏松症早期对小鼠的骨质疏松具有一定的影响,但还需要更多的实验来验证本研究的结论。

Objective Salvianolic acid B is an important bioactive component of traditional Chinese medicine Salvia miltiorrhiza and is widely used in clinic．Recently,salvianolic acid B has been found to have the effect of preventing osteoporosis．On the basis of previous work,this study intends to systematically explore the effect of salvianolic acid B on ovariectomized mice with osteoporosis,and its effect on the osteogenic differentiation of mouse mesenchymal stem cells（MSCs）．Methods Eighteen eight-week-old SPF C57 female mice were divided into sham operation group,osteoporosis group and salvianolic acid B treatment group（6 mice in each group）．The osteoporosis group and salvianolic acid B group underwent bilateral ovariectomy．The sham group maintained normal ovarian structure while removing local fat tissue．All three groups were given antibiotics for anti-infection treatment within 3 days after operation．Within 4 weeks,salvianolic acid B treatment group was given salvianolic acid B 2.5 mg/kg intraperitoneal injection for 12 weeks,once every 2 days,and the other 2 groups were given the same amount of saline at the same time．After 16 weeks,all mice were sacrificed under anesthesia．The bone density of the mouse right posterior femur was measured by MicroCT．The expressions of Runx2 and Osterix in the bone marrow of mouse left posterior femur were analyzed by qRT-PCR．The right posterior femur of mice was ground with liquid nitrogen to extract protein,and the contents of OPG and RANKL were determined by WB．Results The bone mineral density of the femur in the osteoporosis group was lower than that in the sham operation group（P<0.05）,and the bone mineral density of the femur in the salvianolic acid B treatment group was higher than that in the osteoporosis group,but the difference was not significant（P<0.05）．The levels of Runx2 and Osterix in the osteoporosis group were significantly lower than those in the sham operation group（P<0.05）,and the levels of Runx2 and Osterix in the salvianolic acid B treatment group were higher than those in the osteoporosis group（P<0.05）．The levels of OPG and RANKL protein in the osteoporosis group were significantly lower than those in the sham operation group（P<0.05）,while the levels of OPG and RANKL protein in the salvianolic acid B group were higher than those in the osteoporosis group（P<0.05）．Conclusions The early stage of postmenopausal osteoporosis has certain effects on osteoporosis in mice,but more experiments are needed to verify the conclusions of this study．

目的 观察平胃散联合耳穴治疗单纯性肥胖的临床疗效及其对血清神经肽Y(Neuropeptide Y,NPY)和瘦素(Leptin,LP)水平的影响。方法 64例单纯性肥胖患者,采用数字表法随机分为治疗组33例和对照组31例。治疗组予口服平胃散免煎颗粒配合耳穴治疗,对照组予口服奥利司他胶囊治疗,疗程4周。观察治疗前后体质量、体质量指数(bodymass index,BMI)、体脂百分比(Fat%,F%)、腰臀比(Waist Hip Ratio,WHR)、NPY、LP的变化。结果 治疗后,治疗组和对照组体质量、BMI、F%、WHR、相关疾病的危险度均下降(P＜0.001)。比较治疗前后体质量、BMI、F%、WHR差值,治疗组下降均比对照组明显(P＜0.01、P＜0.001)。治疗组临床疗效优于对照组(P＜0.05)。治疗组和对照组血清NPY、LP水平均下降(P＜0.001),且治疗组较对照组下降(P＜0.001)。结论 平胃散联合耳穴有较好的减肥作用,其机制可能是通过降低血清中NPY、LP含量。

Objective Clinical observation of Pingwei Powder combined with auricular point therapy in treating simple obesity and the effect on serum NPY and leptin Levels. Methods 64 cases of simple obesity patients were randomized into treatment group(33 cases) and control group(31 cases). The treatment group was given Pingwei Powder combined with auricular point therapy.The control group was given Orlistat capsules. After being treated for 4 weeks, body weight, bodymass index(BMI), fat% (F%), waist hip ratio (WHR),neuropeptide y (NPY) and leptin(LP) were determined. Results After post-treatment in treatment group and control group, body weight, BMI, F%, WHR, the risk of related diseases all decreased (P＜0.001), The body weight, BMI, F%, WHR before and after treatment were lower than those in the control group(P＜0.01, P＜0.001). The clinical efficacy of the treatment group was better than that of the control group(P＜0.05). Serum NPY and LP levels in treatment group and control group were decreased (P＜0.001), and that the treatment group were lower than of the control group (P＜0.001). Conclusion Pingwei Powder combined with auricular point therapy have better in weight loss, which is possibly by way of reducing serum NPY, LP Levels.
