ABSTRACT
[Objective] To observe the effect of Chai Qin Pingwei Capsule (CQPC) on gastric mucosal cell apoptosis and regulatory genes in rats with bile reflux gastritis. [ Methods ] Wistar rats were randomized into 6 groups: sham-operation group (A), model group (B) , CQPC groups in the dosages of 16.66 (high) ,8.33 (moderate), and 4.17 (low) g/kg respectively (C, D and E respectively), Xiao Chaihu Granules group in the dosage of 10g/kg (F). Except the sham-operation group, the rats in other groups received B- II gastrojejunostomy to induce bile reflux gastritis and were treated with gastric gavage of corresponding drugs according to the experimental design for 4 weeks. Effects of CQPC on gastric mucosal cell apoptosis and the expression of p53 mRNA, Bax and Bcl-2 were observed by enzyme-linked immunosorbent assay (ELISA), hybridization in situ and immunohistochemistry method. [Results] Bile reflux in the model group caused the increase of gastric mucosal cell apoptosis, the up-regulation of wild-type p53 mRNA and Bax protein expression, and the down-regulation of Bcl-2 protein expression, the difference being significant as compared with the sham-operation group (P
ABSTRACT
[Objective] To investigate the efficacy of Xiangsha Yangwei Wan (XYW) on the inhibition of chemotherapy-induced chemical gastritis and upper gastrointestinal symptoms. [Methods] A randomized controlled trial (RCT) was carried out in 87 cases of maligant tumor confirmed by histopathological and cytological examination. All the cases were treated with chemotherapy regimen of adriamycin ( ADM) , adcarbazine ( DTIC) , platinum-based agents, irinotecan (CPT-11) and fluorouraeil (5-FU). Meanwhile, 41 cases in group A were also treated with dexamethason and 5-HT3 receptor antagonist as an essential anti-emesis and with XYW to regulate gastrointestinal function; other 46 cases in group B were given dexamethason and 5-HT3 receptor antagonist only. Seven days after treatment, incidences of chemical gastritis and upper gastrointestinal symptoms were observed and compared between the two groups. [Results] Seven days after chemotherapy, upper gastrointestinal symptoms and signs were relieved in 95.1% (39/41) of the patients of group A and in 76.1 % (35/46) of group B; the occurring rate of chemical gastritis with symptoms was 2.4% (1/41) in group A and 19.6% (9/46) in group B, the differences being significant statistically between the two groups( P - 0.0122) . [ Conclusion ] XYW has an inhibitory effect on chemotherapy-induced chemical gastritis and upper gastrointestinal symptoms.
