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.

Objective:To investigate the clinical effect of reconstruction of the degloving injury of thumb and finger with free perforator flap of superficial peroneal artery.Methods:This is a retrospective study. From June 2020 to June 2023, 18 superficial peroneal artery perforator flaps from 14 calves were used to treat 15 degloved digital wounds of 14 patients in the Department of Hand Surgery, Suzhou Ruihua Orthopaedic Hospital. There were 13 single digital degloving wounds and 1 two-digital degloving wounds. Of which, 3 digits were reconstructed with 2 free perforator flaps of ipsilateral superficial peroneal artery and 12 with a single free perforator flap of superficial peroneal artery. The size of wounds was 4.0 cm×2.0 cm-10.0 cm×4.0 cm, and the flaps were 5.0 cm×3.0 cm-12.0 cm×4.0 cm in size. The donor sites in calves were sutured layer by layer with absorptive sutures. Postoperative follow-ups were conducted through regular outpatient visits, phone calls or WeChat. Survival of flaps, postoperative complications, therapeutic effect of the flaps and patient satisfaction were observed.Results:There was no vascular compromise or wound infection of the flaps. All patients were included in the 4 to 36 months of postoperative follow-up, with an average of 9.86 months. All flaps had good appearance, without obvious swelling. Colour and texture of the flaps was close to the surrounding skin. The flaps had no obvious pigmentation or ulcer and scar hyperplasia at recipient site. Sensation of the flaps recovered to S 2 to S 3. There was no obvious scar hyperplasia, pain or dysfunction at donor sites. According to the comprehensive evaluation scale of flap, the scores were found at 81 to 91, with an average score of 85 in the 14 patients, and of whom 2 were excellent and 12 were good. Patient satisfaction was evaluated according to the Michigan Hand Outcomes Questionnaire (MHQ) and 10 patients were very satisfied and 4 were satisfied. Conclusion:Free perforator flap of superficial peroneal artery is one of the ideal flaps in reconstruction of degloving injury of thumb and fingers. It features constant and multiple perforators, reliable blood supply, high survival rate, flexible in design, thin and a small damage to the donor site.

Objective:To study the effects of parenteral nutrition containing ω-3 fish oil fat emulsion on the inflammatory status of patients with intestinal fistula at the early stage.Methods:A retrospective analysis was conducted on 28 patients with intestinal fistula who were admitted to the Sixth Department of General Surgery of Anhui Provincial Second People's Hospital from November 2023 to May 2024.The patients were either divided into control group(n=15,parenteral nutrition alone group)or study group(n=13,parenteral nutrition plus ω-3 fish oil fat emulsion)according to whether ω-3 fish oil fat emulsion was added to parenteral nutrition.Both groups of patients received parenteral nutrition support treatment,and the study group was given ω-3 fish oil fat emulsion during treatment.The general information,inflammatory factors in the blood,nutrition,and immune status of two groups of patients were collected and compared.The feces samples on the first and 14th day of admission were collected and analyzed by 16S rRNA high-throughput sequencing of gut microbiota.Results:There was no statistically significant difference in the general information,inflammation,nutrition,immune status,and gut microbiota between the two groups of patients on the first day of admission(P>0.05),indicating comparability between the two groups.After two weeks of parenteral nutrition support,the counts of red blood cells,white blood cells,platelets,lymphocytes,and levels of C-reactive protein,glutamate-pyruvate transaminase,aspartate aminotransferase,total bilirubin,direct bilirubin,total protein,albumin,and creatinine in the research group were similar to those in the control group without statistically significant differences(P>0.05).However,the counts of neutrophils and levels of blood urea nitrogen in the study group were significantly lower than those in the control group(P=0.03 and P=0.01).In addition,the abundance of intestinal flora in the study group was significantly higher than that in the control group(P<0.05).At the genus level,the abundance of Bacteroides_uniformis,Parabacteroides_merdae,Alistipes_finegoldii,Streptococcus_constellatus,Christensenella_minuta were different between the two groups after two weeks of treatment(P<0.05).Conclusion:Parenteral nutrition containing ω-3 fish oil fat emulsion can reduce the counts of neutrophils,which may alleviate inflammatory responses for patients with intestinal fistula at the early stage.

Background: s/Aims: Distal pancreatectomy with splenectomy (DPS) is a common surgical procedure for pancreatic body cancer.However, spleen-preserving distal pancreatectomy (SPDP) utilizing the Warshaw technique (WT) in malignancies is generally not favored due to concerns about inadequate resection. This study aims to assess the feasibility and oncologic outcomes of employing SPDP with WT in pancreatic body cancer. Methods: We conducted a retrospective analysis comparing 21 SPDP patients with 63 DPS patients matched by propensity score from January 2018 to November 2022. Clinical outcomes and follow-up data were analyzed using R. Results: Both groups exhibited similar demographic, intraoperative, and pathological characteristics, with the exception of a reduced number of total lymph nodes (p = 0.006) in the SPDP group. There were no significant differences in the rates of postoperative complications, recurrence, or metastasis. Local recurrence predominantly occurred in the central region as opposed to the spleen region.There were no cases of isolated recurrences in the splenic region. Median overall survival and recurrence-free survival times were 51.5 months for SPDP vs 30.5 months for DPS and 18.7 months vs 16.8 months, respectively (p > 0.05). The incidence of partial splenic infarction and left-side portal hypertension in the SPDP group was 28.6% (6/21) and 9.5% (2/21), respectively, without necessitating splenic abscess puncture, splenectomy, or causing bleeding from perigastric varices. Conclusions SPDP did not negatively impact local recurrence or survival rates in selected pancreatic body cancer patients. Further studies are necessary for validation.

BACKGROUND:Degenerative scoliosis is defined as a condition that occurs in adulthood with a coronal cobb angle of the spine>10° accompanied by sagittal deformity and rotational subluxation,which often produces symptoms of spinal cord and nerve compression,such as lumbar pain,lower limb pain,numbness,weakness,and neurogenic claudication.The finite element method is a mechanical analysis technique for computer modelling,which can be used for spinal mechanics research by building digital models that can realistically restore the human spine model and design modifications. OBJECTIVE:To review the application of finite element method in the etiology and treatment of degenerative scoliosis. METHODS:The literature databases CNKI,PubMed,and Web of Science were searched for articles on the application of finite element method in degenerative scoliosis published before October 2023.Search terms were"finite element analysis,biomechanics,stress analysis,degenerative scoliosis,adult spinal deformity"in Chinese and English.Fifty-four papers were finally included. RESULTS AND CONCLUSION:(1)The biomechanical findings from the degenerative scoliosis model constructed using the finite element method were identical to those from the in vivo experimental studies,which proves that the finite element method has a high practical value in degenerative scoliosis.(2)The study of the etiology and treatment of degenerative scoliosis by the finite element method is conducive to the prevention of the occurrence of the scoliosis,slowing down the progress of the scoliosis,the development of a more appropriate treatment plan,the reduction of complications,and the promotion of the patients'surgical operation.(3)The finite element method has gradually evolved from a single bony structure to the inclusion of soft tissues such as muscle ligaments,and the small sample content is increasingly unable to meet the research needs.(4)The finite element method has much room for exploration in degenerative scoliosis.

OBJECTIVE: Asthma imposes a significant global health burden. This study examines changes in the asthma-related disease burden from 1990 to 2021 and projects future burdens for 2050 under different scenarios. METHODS: Using data from the Global Burden of Disease 2021 study, we analyzed asthma incidence, prevalence, mortality, and disability-adjusted life years (DALYs) from 1990 to 2021. We projected the disease burden for 2050 based on current trends and hypothetical scenarios in which all risk factors are controlled. Temporal trends in age-standardized incidence, prevalence, mortality, and DALY rates were explored using Annual Percent Change. RESULTS: In 2021, the age-standardized rates for asthma incidence, prevalence, mortality, and DALYs in China were 364.17 per 100,000 (95% uncertainty interval [ UI]: 283.22-494.10), 1,956.49 per 100,000 (95% UI: 1,566.68-2,491.87), 1.47 per 100,000 (95% UI: 1.15-1.79), and 103.76 per 100,000 (95% UI: 72.50-145.46), respectively. A higher disease burden was observed among Chinese men and individuals aged 70 years or older. Compared to the current trend, a combined scenario involving improvements in environmental factors, behavioral and metabolic health, child nutrition, and vaccination resulted in a greater reduction in the disease burden caused by asthma. CONCLUSION Addressing modifiable risk factors is essential for further reducing the asthma-related disease burden.

BACKGROUND:The highest incidence of spinal fracture is in the thoracolumbar segment,and its symptoms are back pain,posterior convexity deformity,activity limitation,or with spinal cord nerve injury causing lower limb pain,numbness,and even paraplegia and other complications.The finite element method is a digital computer modeling technique,which can simulate the physical model and carry out force analysis realistically.OBJECTIVE:To review the application of finite element method in thoracolumbar spine fractures.METHODS:We searched the Chinese and English literature databases PubMed,Web of Science,and CNKI for relevant literature on the application of the finite element analysis method in spinal thoracolumbar fracture published before March 2024.The search terms in Chinese and English were:finite element analysis methods,biomechanical phenomena,stress analysis,thoracolumbar fractures,spinal fractures.Finally,55 papers were included.RESULTS AND CONCLUSION:(1)The exploration of thoracolumbar fractures caused by different etiologies(osteoporotic,traumatic,and pathological)through the finite element method is conducive to a deeper understanding of the biomechanics of various types of thoracolumbar fractures,and to improve the individualized and fine-tuned treatment of thoracolumbar fractures.(2)The finite element analysis of a single sample or a small number of samples has the chance,and a larger number of samples are required for the future finite element analysis to reduce the chance caused by the sample.(3)The rigid structure of bones alone cannot meet the biomechanical working conditions of the integrity of the physical object,and future finite element models need to incorporate all the structures of the physical object(e.g.,soft tissues,such as muscles and ligaments)as far as possible.(4)The finite element method has been used in more studies on osteoporotic and traumatic thoracolumbar spine fractures,which will need to be more in-depth in the future,and less in the field of pathologic thoracolumbar fractures,which has a wider scope for future research.
