Effects of Weipixiao (胃痞消) on Wnt pathway-associated proteins in gastric mucosal epithelial cells from rats with gastric precancerous lesions / 中国结合医学杂志

<p><b>OBJECTIVE</b>To study the effects of Weipixiao (胃痞消, WPX) on Wnt pathway-associated proteins in gastric mucosal epithelial cells from rats with gastric precancerous lesions (GPL).</p><p><b>METHODS</b>Sprague Dawley rats were randomly divided into control, model, vitacoenzyme (0.2 g·kg(-1)·day(-1)), WPX high-dose (H-WPX, 15 g·kg(-1)·day(-1)), WPX medium-dose (M-WPX, 7.5 g·kg(-1)·day(-1)) and WPX low-dose (L-WPX, 3.75 g·kg(-1)·day(-1)) groups. After successfully establishing the GPL model, the rats were consecutively administered WPX or vitacoenzyme by gastrogavage for 10 weeks. Differential expression of Leucine-rich repeat-containing G-proteincoupled receptor 5 (Lgr5), matrix metalloproteinase-7 (MMP-7), Wnt1, Wnt3a, and β-catenin in gastric mucosal epithelial cells in all groups were immunohistochemically detected, and the images were taken and analyzed semiquantitatively by image pro plus 6.0 software.</p><p><b>RESULTS</b>Gastric epithelium in the model group showed significantly higher expression levels of Lgr5, MMP-7, Wnt1, Wnt3a and β-catenin than those of the control group(P<0.01). Interestingly, we also observed Lgr5+ cells, which generally located at the base of the gastric glandular unit, migrated to the luminal side of gastric epithelium with GPL. The expression levels of Lgr5, MMP-7, Wnt1, and β-catenin were all down-regulated in the L-WPX group as compared with those of both model and vitacoenzyme groups (P<0.05). A similar, but nonsignificant down-regulation in expression level of Wnt3a was noted in all WPX groups (P>0.05).</p><p><b>CONCLUSION</b>Our findings suggested that the therapeutic mechanisms of WPX in treating GPL might be related with its inhibitory effects on the expressions of Lgr5, MMP-7, Wnt1, β-catenin and the aberrant activation of Wnt/β-catenin pathway.</p>

Clinical observation on treatment of acute gouty arthritis by tongfengkang / 中国中西医结合杂志

<p><b>OBJECTIVE</b>To objectively evaluate the clinical therapeutic effect of tongfengkang (TFK) in treating acute gouty arthritis.</p><p><b>METHODS</b>Adopting randomized single blinded controlled trial, the 40 patients were equally divided into two groups. The tested group was treated with TFK, the control group was treated with indomethacin and allopurinol, the therapeutic course for both groups was 10 days.</p><p><b>RESULTS</b>The clinical cure rate in the tested group and the control group was 30% and 35% respectively, and the total effective rate 90% and 95% respectively, with no significant difference between the two groups (P > 0.05). The scores of blood uric acid and symptom significantly lowered in both groups after treatment (P < 0.01), but showed no significant difference between them (P > 0.05). Adverse reaction to the treatment was shown in 3 patients in the control group.</p><p><b>CONCLUSION</b>The therapeutic effect of TFK is similar to that of indomethacin plus allopurinol but with less adverse reaction, it is an effective and safe remedy for treatment of acute gouty arthritis, and worthy for further studying and developing.</p>
