ABSTRACT

The purpose of this study was to investigate the injury of aspirin and clopidogrel on small intestinal mucosa in rats and the protective effect of teprenone.The study found that aspirin and clopidogrel could cause intestinal mucosal injury in rats,which was even worse with dual drugs.The mechanism of mucosal injury included free radical injury induced by aspirin and decreased synthesis of vascular endothelial growth factor (VEGF) by clopidogrel.Teprenone may repair intestinal mucosa via boosting VEGF level.

ABSTRACT

Background:The efficacy of standard triple therapy for eradication of Helicobacter pylori(Hp)is decreasing in recent years,and bismuth-containing quadruple regimen becomes the first-line therapy for Hp infection. However,the application of bismuth has some limitations. Aims:To investigate the efficacy of proton pump inhibitor(PPI)-based standard triple therapy combined with teprenone for Hp eradication. Methods:A total of 155 Hp-infected chronic gastritis patients were enrolled from Jan. 2013 to Dec. 2014 at Aerospace Center Hospital,and were randomly assigned into standard triple therapy group,bismuth-containing quadruple therapy group and teprenone-containing quadruple therapy group. Patients in standard triple therapy group were given rabeprazole sodium 20 mg + amoxicillin and clavulanate potassium 914 mg +clarithromycin 500 mg bid for 10 days. Patients in bismuth-containing quadruple therapy group were given standard triple therapy combined with bismuth potassium citrate 0. 6 g bid for 10 days. Patients in teprenone-containing quadruple therapy group were given standard triple therapy combined with teprenone 50 mg bid for 10 days. Symptoms of patients were evaluated before and after eradication therapy. Four weeks after the end of therapy,13 C-urea breath test( UBT)was reexamined to assess the status of Hp infection. Results:One hundred and fifty-two patients completed the treatment course. By ITT analysis,the eradication rates of standard triple therapy group,bismuth-containing quadruple therapy group and teprenone-containing quadruple therapy group were 69. 8%(37 / 53),86. 5% (45 / 52)and 88. 0% (44 / 50), respectively;by PP analysis,the eradication rates of the three groups were 71. 2%(37 / 52),88. 2% (45 / 51)and 89. 8%(44 / 49),respectively. Eradication rates analyzed by ITT and PP in bismuth-containing quadruple therapy group and teprenone-containing quadruple therapy group were significantly higher than those in standard triple therapy group(P 0. 05). Relieving rates of abdominal pain,abdominal distention and belching in bismuth-containing quadruple therapy group and teprenone-containing quadruple therapy group were higher than those in standard triple therapy group,but statistically significant difference was only found in relieving of abdominal pain between teprenone-containing quadruple therapy group and standard triple therapy group(88. 9% vs. 70. 3% ,P < 0. 05). Adverse effects included transient and mild nausea,diarrhea and black stool, etc. Conclusions:Teprenone-containing quadruple regimen are effective for Hp eradication and symptoms relieving with no severe adverse effects,the efficacy is comparable with bismuth-containing quadruple regimen.

ABSTRACT

Background:Damage of intestinal mucosal barrier is a key factor in the development and progress of acute pancreatitis(AP),and is closely related with the prognosis of the disease. Aims:To investigate the protective effect and possible mechanism of mucoprotective agent teprenone on intestinal mucosal barrier in rats with experimental AP. Methods:Forty-five adult male Sprague-Dawley rats were randomly divided into normal control group(n = 5),AP model group(n = 20)and teprenone treated group(n = 20). AP model was established by subcutaneous injection of cerulein at abdominal wall. Rats in treated group were intervened with teprenone intragastrically before and after model establishment. ELISA was used for measurement of serum interleukin-1(IL-1),IL-6,tumor necrosis factor-α(TNF-α)and amylase;histopathological and ultrastructural changes of small intestinal mucosa were observed by light microscope and transmission electron microscope;Western blotting was used to detect the expressions of tight junction protein occludin and ZO-1. Results:Serum levels of IL-1,IL-6,TNF-α and amylase in AP model group were significantly higher than those in normal control group(P < 0. 05),accompanied by necrosis and exfoliation of small intestinal villus,widening of intercellular tight junctions and downregulation of occludin and ZO-1 expression. While in teprenone treated group,serum levels of proinflammatory cytokines and amylase were significantly decreased as compared with AP model group(P < 0. 05),the villus of small intestine remained intact,and dense tight junctions were observed. Expressions of occludin and ZO-1 in teprenone treated group were upregulated. Conclusions:Teprenone may protect against intestinal mucosal barrier injury in AP model rats by upregulating tight junction protein expression.

ABSTRACT

Background:As a minimally invasive treatment of early gastric cancer,endoscopic submucosal dissection(ESD) proves it could reduce postoperative complications and improve the quality of patients’life. However,ESD-induced gastric ulcer remains a problem. Aims:To evaluate the effect of teprenone combined with rabeprazole on post-ESD ulcer healing and prevention of bleeding after gastric ESD. Methods:One hundred and twenty cases of early gastric cancer or precancerous lesion treated by gastric ESD were divided randomly into group A and group B. Patients in group A were given teprenone combined with rabeprazole,while patients in group B were given rabeprazole alone. The treatment course was 8 weeks. Delayed bleeding rate after ESD and ulcer healing in the two groups were compared. Results:No significant difference was found in rate of delayed bleeding after ESD between the two groups(P = 0. 679). The stage of ulcer had no differences after 7 days of ESD(P > 0. 05),while showed a better healing stage in group A after 30 days and 60 days of ESD(P 0. 05). Conclusions:Teprenone can effectively promote post ESD ulcer healing,especially in the early stage of healing,thus reducing the rate of bleeding after gastric ESD.

ABSTRACT

Objective To investigate the curative effect of Teprenone combined with esomeprazole for reflux esophagitis. Methods 96 cases of reflux esophagitis comfirmed by endoscope were obtained and divied into observation group and control group randomly. Both groups were offered with esomeprazole and motilium. Teprenone was added to the observation group and sucralfate was added to the control group. Clinical effective rate,healing rate,adverse reactions and one-year follow up were observed closely after the course of 8 weeks. Results The relief time of clinical symptom and total effective rate in the observation group were(9.3 ±3.5)d and 95.8% respectively,which were significantly higher than those in the control group(P <0.05). Endoscopic effective rate was 93.8% in observation group and 81.2% in control group respectively and statistically significant difference was observed (P <0. 05). Recurrence rate after one year in the observation group was 8. 3% ,which was significantly lower than in the control group (P < 0.05). One case of headache and nausea occurred in both groups but no severe adverse reaction was observed. Conclusion Teprenone combined with esomeprazole were more effective and more likely to approach the complete cure for reflux esophagitis.
