腹安汤治疗腹泻型肠易激综合征40例疗效观察及机制探讨

目的:探讨腹安汤治疗腹泻型肠易激综合征的临床疗效及对血浆血管活性肠肽(VIP)、P物质(SP)的影响。方法:将80例患者随机分为治疗组和对照组,每组40例,治疗组用腹安汤,对照组用匹维溴胺,对比两组的临床疗效和治疗前后血浆VIP、SP水平。另选20例体检健康者作正常对照。结果:治疗组总有效率92.5%,对照组总有效率77.5%,两组总有效率比较,差异有统计学意义(P<0.05);血浆VIP、SP水平在治疗组用药前后比较,有显著性差异(P<0.05),在治疗组用药后与对照组比较,有显著性差异(P<0.05)。结论:腹安汤治疗腹泻型肠易激综合征疗效明显,值得临床推广应用。其作用机制之一可能是通过调节血浆中VIP、SP的分泌而达到治疗效果。     

肠内营养合早期中药干预对胃大部切除大鼠肠道黏膜细胞更新状态的影响

目的探讨肠内营养合早期中药干预对胃大部切除大鼠肠道细胞更新状态指标(肠道黏膜细胞凋亡率)的影响及机制。方法将60只雄性SD大鼠建立胃大部切除模型,随机分成对照组(C),普通肠内营养组(EN组),肠内营养加四君子汤组(S-EN组)。从术后第1天起连续营养支持7 d,各组营养液的热量、含氮量均相同。观察术前1 d、术后1 d、3 d、7 d的肠道细胞更新状态指标(肠道黏膜细胞凋亡率)的变化。结果S-EN组术后3 d后肠道黏膜细胞凋亡率显著高于C组和EN组(P<0.05)。结论肠内营养合早期中药(四君子汤)干预可提高术后大鼠的营养状态和肠道细胞更新状态,明显改善肠黏膜屏障功能。

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。
