Objective To evaluate the short-term clinical effect of arthroscopic repair of rotator cuff injury with all-suture anchor using a prospective and single-cohort clinical trial.Methods Twenty-five patients with rotator cuff injuries(1.5 cm0.05).Conclusion Arthroscopic rotator cuff repair with all-suture anchor is feasible and safe,and has good short-term clinical effect.

Objective To explore the construction of comprehensive evaluation model of hospital mobile portal from the perspective of user maintenance.Methods The index system was constructed based on CRM-BSC(customer relationship management-the balanced score card)theory.A comprehensive evaluation model of hospital mobile portal was constructed by introducing cloud model.Finally,three hospital official Apps were selected for empirical research to verify the validity of the model.Results Although the construction status of the hospital's official App is good,it varies greatly in different evaluation dimensions.In the"user value"and"user perceived value"dimension performs well,but in the"user knowledge"and"user interaction"dimension performs poorly,need to be further optimized and improved.Conclusion The comprehensive evaluation model can provide comprehensive evaluation standards and tools for mobile portals,and the research results can provide decision support for medical institutions to improve the services of mobile portals.

Objective:To compare the clinical efficacy between reservation and sacrifice of remnants in the footprint area in arthroscopic repair of rotator cuff tear.Methods:A retrospective study was conducted to analyze the clinical data of 32 patients with rotator cuff tear plus remnants in the footprint area (2 cm < tear size <5 cm) who had been admitted to Department of Sports Medicine, The People's Hospital of Northern Jiangsu from May 2020 to July 2021. The patients were divided into 2 groups according to reservation or sacrifice of remnants in the footprint area in arthroscopic repair of rotator cuff tear. In the remnant-reservation group (16 cases): 5 males and 11 females with an age of (61.8±9.9) years, 9 left and 7 right shoulders affected, and (3.7±1.1) cm in size of rotator cuff tear; in the remnant-sacrifice group (16 cases): 4 males and 12 females with an age of (61.3±8.8) years, 8 left and 8 right shoulders affected, and (3.9±0.9) cm in size of rotator cuff tear. The 2 groups were compared in terms of visual analogue scale (VAS), American Shoulder and Elbow Surgeons (ASES) score, Constant-Murley shoulder function score (Constant score), and range of motion of the affected shoulder before surgery, 3 months after surgery and at the last follow-up. The ratio of bilateral abductor muscle strengths (affected side/healthy side) was analyzed and compared between the 2 groups, and the healing of the rotator cuff was evaluated by MRI at the last follow-up.Results:The 2 groups were comparable because there were no significant differences in all their preoperative demographic data ( P>0.05). The 32 patients were followed up for (14.3±3.5) months after surgery. At 3 months after surgery, the VAS score in the remnant-reservation group [1.0 (0.0,1.0) point] was significantly lower than that in the remnant-sacrifice group [1.0 (1.0,1.0) point] ( P<0.05), but there was no significant difference between the 2 groups in ASES score, Constant score or range of motion of the affected shoulder ( P>0.05). At the last follow-up, the ASES score, forward flexion, abduction and ratio of bilateral abductor muscle strengths (affected side/healthy side) in the remnant-reservation group [(96.1±4.8) points, 170.0 (170.0,170.0)°, 160.0 (160.0,170.0)°, and 85.5%±13.8%]were significantly better than those in the remnant-sacrifice group [(91.4±5.9) points, 160.0 (160.0,170.0)°, 150.0 (140.0,155.0)°, and 72.6%±16.9%] ( P < 0.05), but there were no statistically significant differences between the 2 groups in VAS score, Constant score, neutral external rotation angle, or body-side internal rotation ( P>0.05). The Sugaya grading for MRI rotator cuff healing was significantly different between the 2 groups at the last follow-up ( P<0.05). Conclusion:In arthroscopic repair of rotator cuff tear, reservation of remnants in the footprint area can significantly relieve postoperative shoulder pain, and has obvious advantages in restoration of shoulder forward flexion, abduction and abductor muscle strength, leading to better healing of the rotator cuff and the large nodule than the remnant-sacrifice technique.

Objective To investigate the hMOF protein expression in non?small cell lung cancer and explore the relationship between its expres?sion and radiotherapy prognosis. Methods Immunohistochemical staining was used to detect the hMOF expression in 59 cases of non?small cell lung cancer after radiotherapy. The relationship between hMOF expression with clinicopathological and radiation prognosis was analyzed. Results Among the 59 cases of non?small cell lung cancer tissues,there were 30 cases found to be high expression with hMOF. The rate of positive expression of hMOF in non?small cell lung cancer were 50.85%. Clinical stage and hMOF expression were independent predictors for non?small cell lung can?cer. Conclusion The expression of hMOF had a positive correlation with the radiation prognosis in non?small cell lung cancer,which could be used as a prognostic indicator of radiotherapy.
