With the rapid development of competitive sports, the incidence of anterior cruciate ligament (ACL) injury is on the rise. Such injuries may shorten athletes′ career and lead to other long-term adverse consequences. Although athletes generally recover well after ACL reconstruction, many still struggle to return to their pre-injury performance levels. Advances in the understanding of ACL anatomy and injury mechanisms, along with the evolution of surgical techniques and rehabilitation methods, have provided more individualized and tailored options for athletes following ACL injuries. However, there is currently no consensus in China regarding surgical and rehabilitation strategies for competitive athletes aiming to return to sports after ACL injuries. To this end, the Sports Medicine Committee of the Chinese Research Hospital Association and the Editorial Board of the Chinese Journal of Trauma jointly formulated the Expert consensus on surgical treatment and rehabilitation for competitive sports athletes returning to sports after anterior cruciate ligament injury ( version 2025), and presented 14 recommendations covering surgical indications, preoperative rehabilitation, surgical timing, surgical strategies and postoperative rehabilitation strategies, aiming to improve the surgical treatment and rehabilitation system for ACL injuries in competitive athletes and facilitate their return to high-level sports performance after injury.

Acute lateral ankle sprain (ALAS) is one of the most common sport injuries, with high incidence, recurrence and disability rates. Currently, exercise rehabilitation-based non-surgical treatment is the primary management approach for ALAS. However, there remain improper practices such as excessive immobilization or uncontrolled activity, which contribute to recurrent sprains and chronic ankle instability, significantly impairing patients′ athletic function and quality of life. To standardize the non-surgical management of ALAS, improve the cure rates, and reduce the recurrence and disability rates, Chinese Sports Rehabilitation Medicine Training Project of Chinese Medical Association, Foot and Ankle Basics and Orthopedics Group, Orthopedic Branch of Chinese Medical Doctor Association, and Sports Medicine Branch of Jiangsu Medical Association organized relevant experts to formulate Expert consensus on non-surgical treatment for acute lateral ankle sprain ( version 2025), following the principles of scientific vigor, practicality, and innovation. Thirteen recommendations were proposed for standardized treatment protocols across different healing phases, aiming to provide references for standard management of ALAS and improve the therapeutic outcomes.

Objective:To investigate the clinical features, imaging characteristics, surgical strategies, and therapeutic outcomes of otitis media complicated with inflammatory response of local meninges.Methods:A retrospective analysis was conducted on the clinical data of 8 patients with chronic suppurative otitis media complicated with inflammatory response of local meninges, treated by the Department of Otolaryngology, Head and Neck Surgery, PLA General Hospital from 2019 to 2023. Appropriate surgical strategies were selected based on the patient′s clinical manifestations, imaging characteristics, extent of lesions, and facial nerve function. Follow-up was performed postoperatively to assess the therapeutic outcomes.Results:Among the eight patients, there were six males and two females, with an average age of (55.9±12.6) years old. The primary clinical manifestations included otorrhea, hearing loss, facial paralysis, earache, headache, and fever. All patients had a history of chronic suppurative otitis media and tympanic membrane perforation, with varying degrees and types of hearing loss. Seven patients presented with peripheral facial palsy preoperatively, with the House-Brackmann (H-B) grading scale as follows: 4 cases (4/7) in grade Ⅳ, 1 case (1/7) in grade Ⅴ, and 2 cases (2/7) in grade Ⅵ. The mean duration of otorrhea and/or hearing loss was (24.68±12.18) years, while, the average duration of severe headache, aggravated otorrhea and facial paralysis was (2.73±3.92) months. Preoperative high-resolution CT scan of the temporal bone revealed soft tissue shadow in the middle ear and mastoid process, with partial defects in the mastoid cortex. Cranial MRI T1WI showed high signal in the meninges on the affected side, with contrast-enhanced MRI indicating localized meningeal thickening. Four patients (4/8) had diabetes mellitus, and 2 patients (2/8) had a history of middle ear/mastoid surgery. All patients underwent surgical treatment, including thorough removal of lesions, adequate drainage, and facial nerve decompression. Tympanoplasty and hearing reconstruction were performed when conditions permitted. Specifically, 5 patients underwent intact canal wall radical mastoidectomy with facial nerve decompression and tympanoplasty, 2 patients underwent canal wall down mastoidectomy with facial nerve exploration decompression, and 1 patient underwent modified radical mastoidectomy. Postoperatively, patients experienced significant relief and gradual disappearance of ear and head pain. The postoperative H-B grading scale of facial nerve function was as follows: 4 cases in grade Ⅰ (4/8, including 1 case without preoperatively facial palsy), 2 cases (2/8) in grade Ⅱ, and 2 cases (2/8) in grade Ⅲ. Postoperative cranial MRI showed a significant reduction in localized meningeal thickening on the affected side.Conclusions:Patients with long-term chronic suppurative otitis media and/or cholesteatoma who suddenly presented with headache, fever, aggravated otorrhea, and facial paralysis should be suspected of having inflammatory response of local meninges. High-resolution CT of temporal bone and cranial MRI provide crucial diagnostic information. Early surgical exploration and thorough lesion removal are effective treatment methods.

[Purpose]To analyze cancer incidence and mortality in Anhui cancer registration areas in 2019 and the trends from 2015 to 2019.[Methods]Data from 42 cancer registration areas in Anhui Province in 2019 meeting quality control requirements were collected.The incidence,mor-tality,age-standardized rates by Chinese standard population and world standard population,age-specific rate,accumulation rate(0～74 years old)and the top 10 cancers of high incidence and mortality were calculated by urban and rural areas,sexes and age groups.The standard population of China in 2000 was used for age-standardized incidence or mortality rate(ASIRC or ASMRC),and the Segi world standard population was used for age-standardized incidence or mortality rate(ASIRW or ASMRW),respectively.Joinpoint was used to analyze the incidence and mortality trends from 2015 to 2019,and the annual percentage change(APC)was estimated.[Results]In 2019,the reported incidence rate(crude rate)in Anhui cancer registration areas was 282.87/105(313.24/105 for male,251.19/105 for female),ASIRC and ASIRW were 183.85/105 and 178.94/105,respectively,with the cumulative incidence rate of 20.35％.There was no significant change in the incidence of malignant tumors from 2015 to 2019(APC=-1.00％,P＞0.05).The reported mortality rate(crude rate)was 167.20/105(214.67/105 for male,117.67/105 for female),ASMRC and ASMRW were 98.41/105 and 97.15/105,and the cumulative mortality rate was 10.68％.There was no significant change in the mortality rate of malignant tumors from 2015 to 2019(APC=-3.44％,P＞0.05).The incidence and mortality rate of lung cancer ranked the first in urban and rural popu-lations of all genders.The incidence rate of female breast cancer ranked the third and the mortali-ty rate ranked the sixth of all malignancies.The incidence and mortality of malignant tumors in men were higher than those in women,and higher in rural areas than those in urban areas,and the main cancer types of rural and urban areas tended to be the same.[Conclusion]From 2015 to 2019,there was no significant change in the incidence and mortality of malignant tumors in the cancer registration areas of Anhui Province,but it is still necessary to prevent and treat lung can-cer and female breast cancer.

Severe intra-abdominal infections are life-threatening conditions and a significant challenge for surgeons. This article presents a case of an elderly patient with a severe intra-abdominal infection complicated by an anastomotic leak. This patient had experienced prolonged sepsis and multiple surgical traumas. Upon admission to our department, exploratory surgery revealed extensive bowel edema and adhesions, an anastomotic leak, and abdominal contamination with infection. In accordance with the principles of damage control surgery, the anastomotic leak was exteriorized, the abdomen was left open, and continuous intra-abdominal lavage with dual-lumen catheters was implemented to effectively control the infection. Negative pressure wound therapy was used to manage the open abdomen, and a negative pressure-assisted drainage device was used to manage the enteroatmospheric fistula. After granulation of the abdominal wound, split-thickness skin grafting was performed. The enteroatmospheric fistula was converted into an enterocutaneous fistula. A 3D-printed stoma baseplate was used to manage the digestive fistula. Concurrently, enhanced parenteral and enteral nutritional support was provided. Six months later, the patient successfully underwent definitive fistula resection and abdominal wall defect repair.

Objective:To evaluate the efficacy of vacuum sealing drainage (VSD) in the comprehensive management of full-thickness perineal wound dehiscence following pelvic exenteration (PE).Methods:This study employed a descriptive case series design. We retrospectively analyzed the clinical data of 29 patients who developed postoperative perineal wound infections with full-thickness dehiscence after PE. These cases included 16 patients from the Department of General Surgery at Jiangyin People's Hospital (Jiangsu Province) and 13 patients from the Department of Colorectal Surgery at the Second Affiliated Hospital of Naval Medical University (Shanghai Changzheng Hospital). VSD was applied to manage the dehisced wounds, with outcomes assessed based on wound healing time, complications, and follow-up data.Results:A total of 29 patients were included in the study. The operative time for PE was (498 ± 83) minutes. Among them, 23 patients underwent combined sacrococcygeal resection. The median number of VSD devices used was 28 (22, 39). The postoperative perineal wound healing time was 95 (82, 110) days in patients who underwent combined sacrococcygeal resection, 74 (63, 89) days in those without sacrococcygeal resection, 93 (79, 102) days in those treated with simple pelvic-abdominal isolation using a biological basement membrane mesh and 76 (60, 91) days in those who received combined pelvic packing with a pedicled omental flap. All patients uniformly developed Clavien-Dindo grade III complications at 2 weeks postoperatively, manifesting as perineal wound infection and dehiscence, which were successfully managed with VSD therapy. Subsequent evaluation identified delayed (>30 days) grade III complications, including enterocutaneous (3 cases) and urinary (2 cases) fistulae, all requiring surgical revision. All patients completed the follow-up at 6 months postoperatively. Three patients still presented with minimal exudate from the perineal wound, which resolved after standardized wound care and packing with alginate silver ion dressings. Four cases (13.8%) developed stoma high-output syndrome, which improved after oral medication. Eight patients (27.6%) developed adhesive intestinal obstruction, which improved with conservative treatment.Conclusions:VSD demonstrates unique advantages in managing complex wounds. For full-thickness perineal wound dehiscence after PE, VSD is a safe and effective therapeutic strategy.

Objective To compare the effect of different intensity of neuromuscular training(NMT)on muscle strength and knee joint function of patients after anterior cruciate ligament reconstruction(ACLR).Methods From January,2023 to January,2024,60 ACLR patients in Changhai Hospital were selected,and they received the same intensity of NMT from one to eight weeks after surgery.Eight weeks after surgery,they were randomly divided into low intensity group(n=30)and high intensity group(n=30),and then they received different inten-sities of NMT from nine to 16 weeks after surgery,each training session lasted one hour,with three sessions per week,totaly 48 sessions.The Lysholm score,knee flexor and extensor muscle strength and muscle endurance-were compared at eight weeks and 16 weeks after surgery.Results After group training,the Lysholm score significantly increased in both groups(|t|>13.739,P<0.001),and was higher in the high intensity group than in the low intensity group(t=-2.574,P<0.05);in the high intensity group,the relative peak torque and endurance of the extensor and flexor muscles improved at angular velocities of 60°/s,120°/s and 180 °/s(|t|>2.320,P<0.05);in the low intensity group,the flexor peak torque improved at all the three angular velocities(t>2.177,P<0.05),the extensor peak torque improved at angular velocities of 60°/s and 180°/s(|t|>1.715,P<0.05),and the extensor endurance improved at angular velocity of 60°/s(t=-2.293,P<0.05).However,there was no significant difference in the relative peak torque and endurance of the extensor and flexor muscles at all the three angular velocities(P>0.05).Conclusion Both high and low intensity NMT could improve the muscle strength,muscle endurance and knee joint func-tion.Maybe,high intensity is superior to low intensity.Further verification is still needed.

Objective:To investigate the clinical features, imaging characteristics, surgical strategies, and therapeutic outcomes of otitis media complicated with inflammatory response of local meninges.Methods:A retrospective analysis was conducted on the clinical data of 8 patients with chronic suppurative otitis media complicated with inflammatory response of local meninges, treated by the Department of Otolaryngology, Head and Neck Surgery, PLA General Hospital from 2019 to 2023. Appropriate surgical strategies were selected based on the patient′s clinical manifestations, imaging characteristics, extent of lesions, and facial nerve function. Follow-up was performed postoperatively to assess the therapeutic outcomes.Results:Among the eight patients, there were six males and two females, with an average age of (55.9±12.6) years old. The primary clinical manifestations included otorrhea, hearing loss, facial paralysis, earache, headache, and fever. All patients had a history of chronic suppurative otitis media and tympanic membrane perforation, with varying degrees and types of hearing loss. Seven patients presented with peripheral facial palsy preoperatively, with the House-Brackmann (H-B) grading scale as follows: 4 cases (4/7) in grade Ⅳ, 1 case (1/7) in grade Ⅴ, and 2 cases (2/7) in grade Ⅵ. The mean duration of otorrhea and/or hearing loss was (24.68±12.18) years, while, the average duration of severe headache, aggravated otorrhea and facial paralysis was (2.73±3.92) months. Preoperative high-resolution CT scan of the temporal bone revealed soft tissue shadow in the middle ear and mastoid process, with partial defects in the mastoid cortex. Cranial MRI T1WI showed high signal in the meninges on the affected side, with contrast-enhanced MRI indicating localized meningeal thickening. Four patients (4/8) had diabetes mellitus, and 2 patients (2/8) had a history of middle ear/mastoid surgery. All patients underwent surgical treatment, including thorough removal of lesions, adequate drainage, and facial nerve decompression. Tympanoplasty and hearing reconstruction were performed when conditions permitted. Specifically, 5 patients underwent intact canal wall radical mastoidectomy with facial nerve decompression and tympanoplasty, 2 patients underwent canal wall down mastoidectomy with facial nerve exploration decompression, and 1 patient underwent modified radical mastoidectomy. Postoperatively, patients experienced significant relief and gradual disappearance of ear and head pain. The postoperative H-B grading scale of facial nerve function was as follows: 4 cases in grade Ⅰ (4/8, including 1 case without preoperatively facial palsy), 2 cases (2/8) in grade Ⅱ, and 2 cases (2/8) in grade Ⅲ. Postoperative cranial MRI showed a significant reduction in localized meningeal thickening on the affected side.Conclusions:Patients with long-term chronic suppurative otitis media and/or cholesteatoma who suddenly presented with headache, fever, aggravated otorrhea, and facial paralysis should be suspected of having inflammatory response of local meninges. High-resolution CT of temporal bone and cranial MRI provide crucial diagnostic information. Early surgical exploration and thorough lesion removal are effective treatment methods.
