Logistic regression analysis showed that educational background, annual medical costs, awareness of medical and health care APP and attitude towards APP prospect were the factors influencing the utilization of medical and health care APP (OR=0.44，0.69，1.36，1.23，P<0.05).@*Conclusion@#The usage rate of medical and health care APP is general, and sustained utilization rate is low, the APP should enrich menstrual period consumption and figure report, add video recommendation, interactive dating, and other functions, improve female students medical and health care APP cognition, female college students to change health care APP attitude.
ABSTRACT
Objective To explore the imaging features and pathological characteristics of fibrous dysplasia of craniofacial bone. Methods 42 cases with fibrous dysplasia of craniofacial bone confirmed surgically and pathologically were retrospectively analyzed. Results There were 35 cases with single bone involved and 7 cases with poly-bone involved. On CT images, the lesions appeared as glass-like change(79.3%). The main pathological components of the lesion were fiber and fiber-like tissue, which were low signals on both T_1 WI and T_2 WI, and the signal intensity was changed with the accompanied by hemorrhage, necrosis or cystic degeneration. Conclusion CT and MRI are the effective imaging modality in diagnosis of fibrous dysplasia of craniofacial bone.
