Objective To analyze the effect of DRG payment reform on the average expenses of hospitalization in county public hospitals,and to provide evidence and policy recommendations for the promotion and implementation of this policy in the county.Methods Medical record home page of inpatients in all comprehensive public hospitals in Yuhuan County,Zhejiang Province,were collected from 2017 to 2022,and the changes in the structure of average hospitalization expenses before and after the reform were compared through the descriptive analysis,Degree of Structure Variation analysis and Interrupted Time Series analysis.Results The annual Value of Structure Variation (VSV) of medical service expense increased from 1.21％ to 1.49％,accounting for the increase in the positive change of the proportion;the deceleration of the drug expenses slowed down (P<0.05),with the annual VSV increasing from-2.96％ to-2.96％,accounting for a decrease in the magnitude of the negative change in the ratio;the trend of growth in the expenses of consumables ceased (P<0.05),and the annual VSV decreased from 1.98％to 1.30％,accounting for a decrease in the magnitude of the positive change in the ratio.Conclusion The DRG payment reform can enhance the structure of average inpatient expenses in county-level public hospitals,resulting in an increased proportion of medical service expenses.It is advisable to prioritize the valuation of technological labor services,control the growth of consumables expenses,and strengthen the establishment of DRG performance evaluation mechanisms,as well as quality supervision mechanisms for medical services.

Objective To study the value of three dimensional dynamic contrast and digital subtraction MRI in diagnosing breast cancer.Methods 52 patients with breast diseases were enrolled in this study,including 27 malignant lesions and 36 benign lesions verified by histopathology.the morphologic features and enhancement kinetics of breast lesion on MRI were observed.The morphologic manifestation,early-phase enhancement rate,peak enhancement rate,peak time and time-signal intensity curve were evaluated.Results The benign lesions were mainly characterized by regular mass,well-defined border,internal septation,homogeneous enhancement,and the malignant lesions by irregular shape,speculated margin,rim enhancement,inhomogeneous enhancement.The early-phase enhancement rate,peak time and curve type were significantly different between breast benign and malignant lesions(P
