Antiosteoporotic chemical constituents from Er-Xian Decoction, a traditional Chinese herbal formula

AIM OF THE STUDY: Er Xian Decoction (EXD), a traditional Chinese medicine formula, has long been used for the treatment of osteoporosis and menopausal syndrome in China. The present study was designed to investigate the antiosteoporotic constituents of EXD, and evaluate their antiosteoporotic effects in ovariectomized rats. MATERIALS AND METHODS: Osteoblasts in neonatal calvaria cultures and osteoclasts derived from rat marrow cells were used to bioactivity-guided screen the active constituents. The proliferation of osteoblast was assayed by MTT methods. The activity of ALP and TRAP was measured by p- nitrophenyl sodium phosphate assay. The antiosteoporotic effects of icariin (1), anemarsaponin B II (8) and berberine (6) were verified by using OVX rats model. The bone mineral density (BMD) was measured by dual-energy X-ray absorptiometry using the small animal scan mode. The undecalcified longitudinal proximal tibial metaphysical (PTM) sections were cut and stained for the bone histomorphometric analysis. RESULTS: Bioactivity-guided fractionation has led to the successful isolation of antiosteoporotic constituents, i.e., icariin (1), icariside I (2), baohuoside I (3), mangiferin (4), neomangiferin (5), berberine (6), anemarsaponin B (7), anemarsaponin BII (8), anemarsaponin C (9), anemarrhenasaponin I (10), rubiadin-1-methyl ether (11) and obaculactone (12) from EXD. Further study showed that icariin (1), anemarsaponin BII (8) and berberine (6) increased the BMD in ovariectomized rats, and icariin (1) not only increased the bone formation, but also inhibited bone resorption; anemarsaponin BII (8) mainly increased bone formation and berberine (6) only inhibited the bone resorption in ovariectomized rats. CONCLUSION: Our findings demonstrate that multiple ingredients are responsible for antiosteoporotic activity in traditional Chinese medicine formula Er-Xian decoction.     

实验性脾气虚大鼠血清胃泌素、胃窦G细胞的变化及黄芪建中汤的干预

[目的]探讨脾气虚证大鼠血清胃泌素（gastrin,GAS）、胃窦黏膜胃泌素分泌细胞（G）的变化及黄芪建中汤的干预作用。[方法]以三因素复合的方法复制脾气虚证大鼠模型,随后分别以黄芪建中汤低、中、高剂量对脾气虚大鼠进行复健,在干预后不同时间段,分别检测血清木糖浓度、血清肌酸磷酸激酶活性、血清GAS水平及胃窦G细胞等指标。[结果]随用药时间的延长,各用药组上述指标逐步恢复;中、高剂量组用药21天时,与同期模型组比较,差异有显著性（P〈0.05或P〈0.01）;其中,高剂量组对G细胞数的改善作用,优于中剂量组（P〈0.05）。[结论]脾气虚证胃窦G细胞数量减少,释放GAS减少,血清GAS水平降低;黄芪建中汤对脾气虚大鼠有可靠的治疗作用,中、高剂量均为有效用药浓度,尤以高剂量更为理想。     

参芪承气汤加味治疗中风急性期便秘临床研究

目的:观察参芪承气汤加味治疗中风急性期便秘的临床疗效。方法:将74例中风急性期便秘患者随机分为治疗组和对照组,治疗组54例给予参芪承气汤治疗,方药组成:党参30 g,炙黄芪36 g,枳实15 g,炒厚朴20 g,大黄(后下)10 g。对照组20例给予酚酞片治疗,观察两组患者治疗前后便秘症状积分和临床疗效。结果:对照组治疗后便秘症状积分为(8.16±4.83)分,治疗组治疗后为(7.23±3.71)分,两组比较,差异有显著性意义(P0.05);对照组有效率为95.00%,治疗组有效率为92.59%,两组比较,差异无显著性意义(P0.05)。结论:参芪承气汤加味治疗中风急性期便秘能改善症状积分,且有临床疗效较好。
