OBJECTIVE:To observe clinical efficacy and safety of mesalazine combined with Kangfuxin solution retention en-ema in the treatment of active ulcerative colitis(UC). METHODS:A total of 120 patients diagnosed as active UC selected from gastroenterology department of our hospital during Mar. 2012 to Aug. 2014 were divided into observation group and control group according to random number table,with 60 cases in each group. Both groups received conventional treatment of active UC. Control group was additionally given Mesalazine enteric coated tablets 1 g,tid,on the basis of routine treatment.Observation group was ad-ditionally given Kangfuxin solution 30 mL diluted with normal saline 150 mL for enema,qd,on the basis of control group. Both groups were treated for 30 d. The serum levels of TNF-α,IL-1,IL-8,IL-10,SOD,NO and LPO were observed in 2 groups be-fore and after treatment;clinical efficacies,recurrence rates,colonoscopy efficacies and the occurrence of ADR were compared be-tween 2 groups. RESULTS:Before treatment,there was no statistical significance in the serum levels of TNF-α,IL-1,IL-8, IL-10,SOD,NO or LPO between 2 groups(P>0.05).After treatment,the serum levels of TNF-α,IL-1,IL-8,NO and LPO in 2 groups were decreased significantly,while the serum levels of IL-10 and SOD were increased significantly;the serum levels of TNF-α,IL-1,IL-8,NO and LPO in observation group were significantly lower than control group,while the serum levels of IL-10 and SOD were significantly higher than control group,with statistical significance(P<0.05). Clinical response rate,recur-rence rate and colonoscopy response rate of observation group were 83.3%,11.7% and 88.3%,which were significantly better than 66.7%,30.0%,70.0%of control group,with statistical significance(P<0.05).There was no statistical significance in the in-cidence of ADR between 2 groups(P>0.05). CONCLUSIONS:Mesalazine combined with Kangfuxin solution can effectively alle-viate inflammatory reaction in patients with active UC,and reduce oxygen free radical damage with good safety.

Objective To investigate the effect of rebamipide on chronic non-atrophic gastritis (NAG) with erosion and its protection of gastric mucosa from Helicobacter priori(Hp) associated lesions.Methods Patients(n=452)with endoscopically confirmed NAG with erosion from 11 hospitals in China were enrolled and randomly assigned at a ratio of 3:1 to receive either rebamipide(100 mg t.i.d.)or sucralfate(1.0 t.i.d.)for 8 weeks.Hp infected patients received eradication treatment before randomization.Symptoms,endoscopic scores and histological changes were recorded before and after therapy.Concentrations of serum prostaglandin E(PGE:)and oxygen free radical(MDA)were measured in patients from 2 centers.Results Per-protocol analysis(n=415)showed that the dyspeptic symptom score in rebamipide group decreased significantly after eight weeks of treatment. The endoscopic inflammation score in rebamipide group also decreased from 2.65 ±0.09 to 0.60±0.10(P<0.001),which was,significantly better than that of sucralfate group(P<0.001).Histological findings were consistent with the endoscopic findings.There Was a significant elevation(P=0.002)in PGE2 concentration in mucesa from rebamipide-treated subjects [(225.4±18.3) pg/g vs.(266.7±14.7)Pg/g] compared with that in sucralfate group.The concentration of MDA significantly decreased from(325.9±65.6)mmoL/g to(216.5±61.5)mmol/g,which is markedly different from that of sucralfate group(P=0.046).No statistical difference was found between Hp eradication group,Hp infection group and Hp negative group,regarding the effect of Rebamipide.Conclusion Compared to sucralfate,Rebamipide demonstrates a superior effect on improvement of dyspepsia symptom and endoscopic findings in erosive NAG,which is not influenced by Hp infection.
