Clinical results showed the effective rate in treating the chronic or Pi-deficiency diarrhea as well as the negative conversion rate and improvement rate of routine scatologic analysis were all higher in the treated group than those in the control group (P < 0.05); while no significant difference was found in negative conversion rate of scatologic cultivation and rotavirus antigen and urinary D-xylose content after treatment, compared with those before treatment (P > 0.05).
