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 systematically review the research progress in the evaluation of the integration of medical care and prevention in China.Methods:The keywords "medical care","prevention","public health", and "evaluate" were used to search in Chinese databases (CNKI, Wangfang and VIP Chinese Science and Technology Journal) and English databases (PubMed, Embase, Cochrane, and Web of Science) from March 17, 2009, to August 7, 2024. The language of studies was restricted to Chinese and English. The inclusion criteria were the integration of medical care and prevention occurring at one of the three dimensions, i.e., macro-system level, meso-institution and professional level and micro-service level. The study area should be located in China. The studies about theoretical exploration, policy analysis, and review of theory and practice in foreign countries regarding the integration of medical care and prevention and the article types of conference abstract, editorial, letter, and news were excluded. A total of 30 studies (in Chinese) were finally included. The definition of the integration of medical care and prevention, study design, evaluation objects, and specific evaluation indicators were compared and analyzed.Results:The evaluation objects of the included studies were mainly primary health staff and patients with chronic diseases in primary care. The study designs were mainly cross-sectional studies ( n=18) and controlled trials ( n=8). The included studies involved a total of 39 specific evaluation indicators at the macro-system level (5), meso-institutional level (8), professional level (11), micro-service level (12), and outcome level (3). Conclusion:Research on the integration of medical care and prevention is still in the development stage. The existing studies lack commonly recognized evaluation indicators regarding the integration of medical care and prevention.

Objective:To study the clinical value of SpyGlass direct visualization system-guided radiofrequency ablation (RFA) combined with biliary stent implantation in the treatment of malignant biliary stricture.Methods:Clinical data of 29 patients with advanced malignant biliary stricture without surgical resectability who received palliative endoscopic treatment in Drum Tower Hospital of Nanjing University Medical School and Wuxi No.2 People’s Hospital were retrospectively analyzed, including 20 males and 9 females, aged (70.3±11.5) years. Patients were divided into two groups: the SpyGlass-guided biliary RFA combined with biliary stent implantation treatment group (combined group, n=14) and the simple biliary stent treatment group (simple stent group, n=15). The age, gender, body mass index (BMI), the total bilirubin, jaundice remission, postoperative complications, stent patency time and survival period were compared between the two groups. Results:Among 29 cases, 20 were cholangiocarcinoma (69.0%), 4 were hepatocellular carcinoma (13.8%), 3 were carcinoma of gallbladder (10.3%), and 2 were ampullary carcinoma (6.9%). There were no statistically significant difference in age, male proportion, primary tumor proportion, BMI and total bilirubin between the groups (all P>0.05). The postoperative total bilirubin of the combined group was 41.5(29.8, 52.5)μmol/L, and that of the stent group was 55.4(31.5, 107.1)μmol/L ( Z=1.18, P=0.247). There were 11 cases of jaundice remission in the combined group and 10 in the stent group ( χ2=0.51, P=0.474). The stent patency time in the combined group was 90 (77, 250) days, and that in the stent group was 100 (60, 190) days ( Z=0.28, P=0.793). There was no significant difference in cumulative survival rates and incidence of postoperative complications between the two groups ( P>0.05). Conclusion:SpyGlass-guided biliary RFA combined with biliary stent implantation neither improves the treatment efficacy nor prolongs stent patency time in patients with malignant biliary strictures.

Objective To explore the differences in scapular motion and shoulder function between patients suffering from rotator cuff tears(RCT)with and without type Ⅲ scapular dyskinesis(SD).Meth-ods Between September 2021 and March 2023,sixteen patients suffering from rotator cuff tears with SD(SD group)and 17 counterparts without SD(non-SD group)were recruited from the Sports Hospital of the General Administration of Sport of China.Their scapular motion was assessed by measuring three parameters in the X-rays,including scapular spine line(LSS),scapular upward rotation angle(SU-RA),and coracoid upward shift distance(CUSD).Moreover,their shoulder range of motion in flexion,abduction and external rotation were recorded,and further evaluated using the Pain Visual Analog Scale(VAS)and American Shoulder and Elbow Surgeons Score(ASES).Results No significant differenc-es were found between the two groups in the average score of SURA,CUSD and LSS at 0°～30° shoul-der abduction,or in that of CUSD and LSS at 60°～90°shoulder abduction.However,the average SU-RA score of the SD group at 60°～90°shoulder abduction was significantly greater than the other group(P<0.05).The shoulder ranges of motion during active flexion,abduction and external rotation were significantly smaller in the SD group than in the non-SD group(P<0.05).Moreover,the average VAS score in the SD group was significantly higher than the non-SD group(P<0.05),while the average ASES score was significantly lower than the latter group(P<0.05).Conclusions RCT patients type III SD exhibits greater scapular upward rotation during shoulder abduction compared to those without SD.Moreover,the former patients suffer from more severe pain and have worse shoulder range of motion and functional performance than the latter.

Objective:The nasal swell body（NSB） consists of the nasal septal cartilage, nasal bone, and swollen soft tissue, all of which are visible during endoscopic and imaging examinations. Although the function of the NSB remains uncertain, there is evidence to suggest that it plays a vital role in regulating nasal airflow and filtering inhaled air. Based on anatomical and histological evidence, it is hypothesized that the NSB is indispensable in these processes. This study aims to investigate the impact of NSB on nasal aerodynamics and the deposition of allergen particles under physiological conditions. Methods:The three-dimensional （3D） nasal models were reconstructed from computed tomography （CT） scans of the paranasal sinus and nasal cavity in 30 healthy adult volunteers from Northwest China, providing basis for the construction of models without NSB following virtual NSB-removal surgery. To analyze the distribution of airflow in the nasal cavity, nasal resistance, heating and humidification efficiency, and pollen particle deposition rate at various anatomical sites, we employed the computed fluid dynamics（CFD） method for numerical simulation and quantitative analysis. In addition, we created fully transparent segmented nasal cavity models through 3D printing, which were used to conduct bionic experiments to measure nasal resistance and allergen particle deposition. Results:①The average width and length of the NSB in healthy adults in Northwest China were （12.85±1.74） mm and （28.30±1.92） mm, respectively. ②After NSB removal, there was no significant change in total nasal resistance, and cross-sectional airflow velocity remained essentially unaltered except for a decrease in topical airflow velocity in the NSB plane. ③There was no discernible difference in the nasal heating and humidification function following the removal of the NSB; ④After NSB removal, the deposition fraction（DF） of Artemisia pollen in the nasal septum decreased, and the DFs post-and pre-NSB removal were（22.79±6.61）% vs （30.70±12.27）%, respectively; the DF in the lower airway increased, and the DFs post-and pre-NSB removal were（24.12±6.59）% vs （17.00±5.57）%, respectively. Conclusion:This study is the first to explore the effects of NSB on nasal airflow, heating and humidification, and allergen particle deposition in a healthy population. After NSB removal from the healthy nasal cavities: ①nasal airflow distribution was mildly altered while nasal resistance showed no significantly changed; ②nasal heating and humidification were not significantly changed; ③the nasal septum's ability to filter out Artemisia pollen was diminished, which could lead to increased deposition of Artemisia pollen in the lower airway.

Objective To investigate the expression of hypoxia-inducible factor-1α(HIF-1α),matrix metalloprotein-ase(MMP)-1 and MMP-2 in the serum of patients with diabetic retinopathy(DR),and to analyze their relationship with the stage of DR and angiogenesis.Methods A total of 280 patients with type 2 diabetes mellitus(T2DM)and no DR who were hospitalized in our hospital from December 2020 to December 2021 were selected as the T2DM group;276 DR patients who were hospitalized in the ophthalmology department of our hospital during the same period were selected as the DR group;another 282 healthy subjects who underwent physical examination in our hospital were selected as the normal group.There were no significant differences in gender and age distribution among the normal group,T2DM group and DR group(both P＞0.05).According to the results of fundus examination and fluorescein angiography,the patients in the DR group were divided into non-proliferative diabetic retinopathy(NPDR)group(129 patients)and proliferative diabetic reti-nopathy(PDR)group(147 patients).The fasting plasma glucose(FPG),glycosylated hemoglobin(HbA1c)and serum HIF-1 α,MMP-1,MMP-2 levels of subjects in the normal group,T2DM group and DR group,as well as NPDR group and PDR group were compared.The serum basic fibroblast growth factor(bFGF),angiopoietin-1(Ang-1)and vascular endo-thelial growth factor(VEGF)levels of subjects in the normal group,T2DM group and DR group,as well as NPDR group and PDR group were compared.Pearson correlation analysis was used to analyze the correlation between serum HIF-1α,MMP-1,MMP-2 and bFGF,Ang-1,VEGF levels in DR patients.Results The FPG,HbA1c and serum HIF-1α,MMP-1,MMP-2 levels of the T2DM group and DR group were higher than those of the normal group,and the differences were statis-tically significant(all P＜0.05).The serum HIF-1α,MMP-1 and MMP-2 levels of the DR group were significantly higher than those of the T2DM group(all P＜0.05);there were no significant differences in FPG and HbA1 c between the two groups(both P＞0.05).The serum HIF-1α,MMP-1 and MMP-2 levels of the PDR group were significantly higher than those of the NPDR group(all P＜0.05);there were no significant differences in FPG and HbA1c between the two groups(both P＞0.05).The serum bFGF,Ang-1 and VEGF levels of the T2DM group and DR group were higher than those of the normal group,and the differences were statistically significant(all P＜0.05).The serum bFGF,Ang-1 and VEGF levels of the DR group were significantly higher than those of the T2DM group(all P＜0.05).The serum bFGF,Ang-1 and VEGF levels of the PDR group were significantly higher than those of the NPDR group(all P＜0.05).Pearson correlation analysis showed that HIF-1α,MMP-1 and MMP-2 were positively correlated with bFGF,Ang-1 and VEGF levels in DR patients(all P＜0.05).Conclusion The serum HIF-1α,MMP-1 and MMP-2 levels of DR patients are abnormally elevated,and are closely related to the progression of DR and angiogenesis.These parameters can be used to predict the disease development trend and guide clinical intervention.

Lateral epicondylitis is a common clinical disease with characteristics of lateral elbow pain, insidious onset and easy recurrence, which can cause forearm pain and decreased wrist strength, seriously affecting patients′ daily life and work. Although there are various treatment methods for lateral epicondylitis with different effects, standard treatments are still lacking nowadays. Platelet-rich plasma (PRP) has good effects on bone and tendon repair, and is now widely used in the treatment of lateral epicondylitis. However, there is a lack of a unified understanding of the technology and specifications of PRP in the treatment of lateral epicondylitis. Therefore, the Sports Medicine Branch of the Chinese Medical Association and Physical Medicine and Rehabilitation Branch of the Chinese Medical Association organized experts in the fields of sports medicine and rehabilitation medicine in China to formulate the "clinical expert consensus on platelet-rich plasma treatment for lateral epicondylitis (2022 version)", and proposed suggestions based on evidence-based medicine mainly from the concept, epidemiology and pathophysiology of lateral epicondylitis, symptoms, signs and imaging manifestations of lateral epicondylitis, PRP concept and application component requirements, quality control of PRP preparation technology, indications and contraindications of PRP in the treatment of lateral epicondylitis, PRP injection in the treatment of lateral epicondylitis, application of PRP in the operation of lateral epicondylitis, related problems after PRP treatment of lateral epicondylitis, evaluation of the results after PRP treatment of lateral epicondylitis, and health and economic evaluation of PRP treatment of lateral epicondylitis, so as to provide guidance for clinical diagnosis and treatment.

The emergence of immune checkpoint inhibitors (ICIs) has dramatically changed the therapeutic outlook for patients with non-small cell lung cancer (NSCLC). Preoperative neoadjuvant immunotherapy has been paid more and more attention as an effective and safe treatment. Neoadjuvant immune therapy, however, the relevant research started late, relatively few research results and mainly focused on the small sample size of phase I and II studies, treatment itself exists many places it is not clear, also in benefit population screening, the respect such as the choice of treatment and curative effect prediction has not yet reached broad consensus. This paper reviews the important studies and recent achievements related to neoadjuvant immunotherapy, aiming to comprehensively discuss the procedures and existing problems of this kind of therapy from three aspects of beneficiary groups, treatment cycle and efficacy prediction.
