Objective To compare the diagnostic value of ultrasonography and CT in acute appendicitis.Methods A retrospective analysis was conducted on 279 patients who were diagnosed with acute appendicitis and followed emergency surgery.Patients were divided into different subgroups based on postoperative pathological results and body mass index(BMI),and the pathological results were used as the gold standard to analyze whether there were differences in the diagnostic accuracy of ultrasonography and CT examination for acute appendicitis.Results A total of 279 patients with confirmed acute appendicitis,with 64 cases of simple appendicitis,127 cases of suppurative appendicitis,and 88 cases of gangrenous appendicitis according to pathological classification.The diagnostic accuracy of ultrasonography was 68.75%(44/64),73.22%(93/127),and 81.81%(72/88),respectively.The diagnostic accuracy of CT was 71.87%(46/64),82.67%(105/127),and 90.90%(80/88),respectively.There was no statistically significant difference in diagnostic accuracy between the two examinations(P>0.05).Subgroup analysis based on patient BMI showed that there was no difference in diagnostic accuracy of the two examinations for patients with normal BMI(P>0.05),while for overweight and obese patients,the diagnostic accuracy of CT was better than that of ultrasonography,with a statistical difference(P<0.05).Conclusion There is no difference in the diagnostic accuracy of ultrasonography and CT examinations for acute appendicitis of different pathological types.But for overweight and obese acute appendicitis patients,the diagnostic accuracy of CT examination is superior to ultrasonography.

OBJECTIVE: Digital therapy is important in treating motor system disease. The outcome of digital therapy in post-operative rehabilitation of knee anterior cruciate ligament (ACL) reconstruction is assessed. METHODS: 142 patients are treated with digital rehabilitation therapy after ACL reconstruction. Patients' pain score, joint motion, lower limb function score, anxiety score are statistically analyzed. Patients' satisfaction, device usage and adverse events are documented. RESULTS: At post-operative 1st day, 8th weeks, 12th weeks, pain score are 4, 2, 1, knee joint range of motion are 55°, 110°, 143°, lower limb function score are 18, 56, 76, anxiety score are 32.5, 26, 23.5 respectively. Patients' satisfaction are 9.4. Mean duration of device usage is (177.6±38.0) minutes per week. Rehabilitation-related and device-related adverse event does not happen. CONCLUSIONS Digital therapy promotes post-operative rehabilitation after ACL reconstruction.
