Background:Gastrointestinal dysmotility is frequently seen in patients with chronic obstructive pulmonary disease ( COPD). Simo Decoction is used for promoting gastrointestinal motility in clinical practice. Aims:To study the effect of Simo Decoction on gastrointestinal symptoms and motility in patients with COPD. Methods:Thirty-six patients with stable COPD in Shiyan Renmin Hospital from Sep. 2012 to Jun. 2013 were enrolled and received a 28-day course treatment of Simo Decoction oral solution,19 healthy volunteers were served as controls. All subjects were assessed with gastrointestinal symptom rating scale(GSRS). Electrogastrography was performed and levels of vasoactive intestinal peptide(VIP)and intestinal fatty acid-binding protein( I-FABP)in peripheral blood were measured. Patients with COPD were re-examined for the above-mentioned parameters after treated with Simo Decoction. Results:The baseline GSRS score and serum I-FABP level in COPD patients were significantly increased as compared with controls(P<0. 05),while the baseline serum VIP level,as well as the fasting and postprandial normal gastric slow wave percentage in COPD patients were significantly decreased(P <0. 05). After 28-day course of Simo Decoction treatment,all these parameters in COPD patients were improved as compared with those before treatment(P<0. 05),serum levels of VIP,I-FABP and normal gastric slow wave percentage were similar to those of controls. Conclusions:Simo Decoction can ameliorate the gastrointestinal symptoms and dysmotility in patients with COPD. The regulatory effect of Simo Decoction on gastrointestinal motility might be bidirectional.

Aim To study effects of loganin and morro-niside on aging astrocytes induced by D-galactose. Methods Cortex astrocytes of newly born rats were cultured in vivo and indentified by immunofluorescence method.Firstly,appropriate D-galactose concentration was selected and effects of loganin and morroniside on proliferation activity of aging astrocytes induced by D-galactose were determined by MTT test.Then SOD, MDA were taken as indicators to study the effects of loganin and morroniside on aging astrocytes induced by D-galactose.Thirdly,growth factors like gliar cell line-derived neurotrophic factor (GDNF),basic fibro-blast growth factor (bFGF)tested by ELISA method and expression of Bax,caspase-3,phospho-extracellu-lar signal-regulated kinese (p-ERK1 /2),phospho-mi-togen-actived protein kinase /extracellular signal-regu-lated kinase kinase (p-MEK1 /2)were taken as indi-cators to discuss the potential protection mechanism. Results Loganin and morroniside exerted certain effects on proliferation of aging astrocytes induced by D-galactose,improving SOD,GDNF,bFGF release and lowering MDA release significantly (P <0.05 ). The expressions of Bax and caspase-3 proteins had no difference between model group and loganin group, morroniside group.While the expressions of p-ERK1 /2,p-MEK1 /2 of loganin group,morroniside group were improved significantly compared with model group.Conclusion Loganin and morroniside have protective effects on aging astrocytes induced by D-ga-lactose,and increase the proliferation ability.Protec-ting their antioxidant systems and improving the expres-sion of p-ERK1 /2,p-MEK1 /2 proteins are possible mechanisms.

We studied medium alkalinization in Salvia miltiorrhiza suspension cultures treated with salicylic acid and the effect of Ca2+ in this process through application of calcium channel antagonists (Verapamil, LaCl3, LiCl, 2-APB) and ionophore A23187. The results show that salicylic acid could induce significant medium alkalinization in S. miltiorrhiza culture. Verapamil and LaCl3 or LiCl and 2-APB, two different groups of calcium channel antagonist, significantly inhibited the medium alkalinization induced by salicylic acid. However, the suppression effect of verapamil or LaCl3 on medium alkalinization induced by salicylic acid was higher than that of LiCl or 2-APB. When two types of calcium channel inhibitor (LaCl3 and 2-APB) were used together, the medium alkalinization induced by salicylic acid was completely suppressed and even reduced the pH in medium. On the other hand, A23187 could promote the medium alkalinization. Based on the results above, we speculated that salicylic acid could induce significant medium alkalinization in S. miltiorrhiza culture, depending on the calcium from both extracell and intracell. Moreover, calcium from extracell plays a more dominant role in this process. Reveal of relationship in this research between Ca2+ and medium alkalinization can provide theory evidence for mechanism of the plant secondary metabolism.
