Digital economy, centered around information technology, encompasses digital content, digital industries, digital commerce, and represents a new global economic form. Its application can bring about new development opportunities and enhance efficiency. Rural revitalization is an important recent national strategy aimed at strengthening economic, social, and ecological aspects of rural development, promoting sustainable urban-rural integration. This involves the development of agriculture, rural infrastructure, the creation of beautiful rural landscapes, and ensuring the livelihood of rural residents. The digital economy plays a crucial role in rural revitalization, relying on information technology and employing digitalization, networking, and intelligence to drive industrial transformation, enhance efficiency, and promote innovation, thus forming a new economic model. Specifically in rural areas, the digital economy builds rural e-commerce platforms, offering new sales channels for farmers, creating smart agricultural ecosystems, establishing environmentally friendly foundations for sustainable agriculture, and upgrading rural financial services through digitization, optimizing the allocation of rural financial resources. This accelerates the digitization of rural tourism development and spurs the growth of surrounding rural service industries. Therefore, the digital economy holds significant practical importance for rural revitalization.

Through this examination, the study aims to provide a comprehensive understanding of the challenges and opportunities for integrating sports and medicine in China, with the understanding that sports can serve as a valuable form of medicine.

Background: Tendon avulsion at the musculotendinous junction caused by digit avulsion amputation is still a challenging problem. We aimed to compare the tendon functional outcomes of two repair methods for tendon avulsion rupture at the musculotendinous junction in patients with complete thumb avulsion amputations. Methods: A retrospective study was performed to evaluate patients with complete thumb avulsion amputations whose tendons were repaired through reattachment to muscle (group I) or tendon transfer (group II) between July 2008 and October 2019. Outcomes of total range of motion, pinch strength, grip strength and reoperation rate were included. Results: A total of 23 patients met the inclusion criteria, with a mean follow‐up of 16.6 ± 4.2 months. Total active range of motion was comparable between groups I and II (P = 0.095). Pinch strength of group I was lower than group II (P = 0.001). The result of grip strength was found to be similar (P = 0.075). In addition, there was no significant difference in reoperation rate (P > 0.05). Conclusion: Tendon transfer can attain higher pinch strength for replantation of thumb avulsion amputations. It is recommended for patients with jobs that demand higher strength. [ABSTRACT FROM AUTHOR]

Aim: To retrospectively analyze and compare ultrasound-assisted localization in situ with the traditional, open incision method for treating cubital tunnel syndrome (CuTS)., Material and Methods: We retrospectively analyzed 51 patients treated between 2018 and 2022 and categorized them according to treatment method: ultrasound-assisted precise localization in situ decompression (n=21; Cohort 1) and traditional open incision in situ decompression (n=30; Cohort 2). We additionally collected Visual Analogue Scale (VAS) scores, Vancouver Scar Scale (VSS) scores, modified Bishop scores, aesthetic appearance, preoperative Dellon's stage, and analgesics requirements. Additional dependent variables of interest included operation time, hospital stay duration, complications, and reoperation rate., Results: Neither cohort demonstrated significant changes in Dellon's stage, modified Bishop score, or VAS scores between baseline and 6 weeks postoperative. Cohort 1 showed better aesthetics and postoperative VSS and VAS scores than Cohort 1. In addition, Cohort 1 enjoyed a significantly shorter mean operation time and hospital stay. Cohort 1 had 5 (23.80%) complications, including superficial infection (n=1), hematoma (n=1), and incomplete decompression (n=3). Cohort 2 had 9 complications (30.00%), including superficial infection (n=2), hematoma (n=2), and severe scarring (n=5). The partial, incomplete decompression cases in Cohort 1 and the severe scar case in Cohort 2 were treated with reoperation., Conclusion: Both procedures effectively treated most cases of CuTS and were associated with good postoperative outcomes. Patients who underwent ultrasound-assisted localization in situ decompression had shorter surgeries and hospital stays, better postoperative aesthetics, better VSS and VAS scores, and required less pain medication during the postoperative period. Traditional open incision in situ produced a more thorough decompression.

Purpose: Whether an innervated reverse digital artery island flap is superior to a non-innervated reverse digital artery island flap still remains controversial. We aimed to compare the clinical outcomes of the two flaps in repairing finger pulp soft tissue defects., Methods: Medical records of patients who underwent finger pulp reconstruction between January 2007 and December 2017 were evaluated retrospectively. A total of 45 patients were included. Twenty underwent sensory nerve reconstruction with cutaneous branches of the proper digital nerve, and 25 underwent the surgery without sensory nerve reconstruction. Surgical results, complications and sensory function were collected for analysis. Sensory function was assessed by static two-point discrimination and the modified sensory evaluation standard of British Medical Research Council., Results: The average operation time of innervated flaps was 23 min longer than non-innervated flaps. All 45 flaps survived completely. There was no significant difference in complications between groups. The average follow-up was 22 months. At the final follow-up, five non-innervated flaps had no recovery of static two-point discrimination. The average static two-point discrimination of the remaining 20 non-innervated flaps was larger than that of innervated flaps. Innervated flaps consistently achieved higher sensory function grades according to the modified sensory evaluation standard of British Medical Research Council., Conclusion: An innervated reverse digital artery island flap can achieve better sensory function recovery in a shorter time. This procedure did not increase the incidence of complications, although it extended the operation time. It has proven to be a good technique for finger pulp reconstruction., (© 2022 Royal Australasian College of Surgeons.)

Objective: To explore the effectiveness of modified anterolateral thigh perforator flap pedicled by cross-bridge microvascular anastomosis in treatment of soft tissue defects in the middle and lower segments of the leg., Methods: Between March 2011 and June 2015, 15 cases with skin and soft tissue defects in the middle and lower segments of the legs were treated. There were 9 males and 6 females, aged 22-48 years (mean, 32.6 years). Of whom, 8 patients caused by traffic accidents, 5 by machine twist, and 2 by crash injury of heavy object. The mean interval from injury to admission was 82.6 hours (range, 2 hours to 1 week). The area of defect ranged from 13 cm×9 cm to 23 cm×16 cm. After primary debridement and vaccum sealing drainage treatment, the defects were repaired with modified anterolateral thigh perforator flap pedicled by cross-bridge microvascular anastomosis. The size of flap ranged from 15 cm×10 cm to 25 cm×15 cm. The donor sites were sutured directly or repaired with the skin grafts. The pedicle division was done at 4 weeks after operation., Results: After operation, venous crisis occurred in 1 case and distal skin necrosis in 2 cases which was healed by dressing change. The other tissue flaps survived successfully and wounds healed by first intention. All skin grafts at donor site survived after operation, and primary healing of wound was obtained. All patients were followed up 6-24 months (mean, 13 months). All flaps were characterized by soft texture, satisfactory appearance, and restoring the protective sensation. Moreover, the two-point discrimination ranged from 15 to 28 mm (mean, 19.5 mm) at 6 months after operation. The function of both lower extremities were normal without obvious contracture of scar at donor site., Conclusion: Modified free anterolateral thigh perforator flap, with little damage in donor site, a reliable blood supply by making a cross-bridge microvascular anastomosis with pretibial or posterior tibial blood vessel on normal leg, is a reliable alternative method for repairing soft tissue defects with the main vessels of serious injury in the middle and lower segments of the leg.
