Objective To investigate the effects of DIF combined with histopathology and ELISA on the diagnostic accuracy of MMP.Methods Biopsy tissues were collected from patients with MMP(n=29)and without(n=29).Tissues were stained by DIF and HE respectively.To analysis the diagnostic efficacy of two diagnostic methods(using only histopathology and ELISA,and combining with DIF)and the impact of multiple factors on the accuracy of histopathology and DIF.Results The combination of DIF can improve the sensitivity,negative predictive value,diagnostic accuracy and area under curve of MMP.The course of disease has a significant impact on the diagnostic accuracy of DIF.The longer course,the higher accuracy(P<0.05).Conclusions DIF combined with histopathology and ELISA can improve the accuracy for the diagnosis of MMP.For difficult cases,multiple and multi-site biopsies may be necessary to improve the diagnostic accuracy of DIF on MMP.
