Objective To investigate the effect of racecadotril granules combined with montmorillonite on infantile rotavirus enteritis and myocardium enzymogram.Methods Retrospective a total of 275 infants and young children with rotavirus enteritis treated in Seventh Hospital of Ningbo from September 2014 to January 2016,were divided into the control group and the combined treatment group according to the treatment method.The combined treatment group were treated with montmorillonite powder and racecadotril granules, the control group were treated with montmorillonite powder.The negative rate of stool were observed three days after treatment,compared the symptom relief time,the level of inflammatory cytokines and myocardial enzyme spectrum between two groups before and after treatment .Results The stool negative rate of combined treatment group ( 79.31%) higher than the control group(67.69%) after three days of treatment;the levels of IL-18,IL-6 and hs-CRP in the combined treatment group were lower than those in the control group(P<0.05);the antiemetic time,dehydration correction time and recovery time of stool were shorter in combination therapy group than those in control group(P<0.05);there was no difference in the levels of myocardial enzyme between the two groups before treatment.The level of CK-MB,LDH,CK and AST in the two groups after treatment were lower than before treatment,and the level of CK and CK-MB in the combined treatment group was lower than the control group ( P<0.05 ) .Conclusion Racecadotril granules combined with montmorillonite powder has a good therapeutic effect on infantile rotavirus enteritis can significantly improve clinical symptoms, reduce the levels of inflammatory cytokines in patients.
