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 evaluate the effectiveness of active screening in improving the detection rate of carbape-nem-resistant Enterobacterales(CRE)in the intensive care units(ICUs).Methods From July 2023 to June 2024,active screening of rectal swab CRE was conducted on ICU patients in 10 hospitals.ICU patients who underwent ac-tive screening from July 2023 to June 2024 were selected as the study group,while those who did not undergo active screening from July 2022 to June 2023 were selected as the control group.Difference in CRE detection rates between the two groups of patients was compared.Results A total of 7 803 ICU patients were included in the study group,744 CRE strains were detected,with a detection rate of 9.53％,out of which 304 CRE strains were detected through routine detection(detection rate 3.90％),3 707 patients underwent active screen,440 CRE strains were detected(detection rate 11.87％).7 561 ICU patients were included in the control group,out of which 250 CRE strains were detected through routine detection,with a detection rate of 3.31％.There was a statistically significant difference in the overall detection rate of CRE between two groups of patients(x2=246.18,P＜0.001).In the study group,CRE detection rate of active screening(11.87％)was higher than that of routine detection(3.90％),with statistically significant difference(x2=264.26,P＜0.001).A total of 17 CRE strains were detected from the study group.The proportions of Klebsiella pneumoniae(80.92％vs 73.41％)and Serratia marcescens(2.30％vs0.23％)in the routine detection group were both higher than in the active screening group,while the proportion of Escherichia coli in the routine detection group was lower(8.22％vs 19.55％),all with statistically significant differences(all P＜0.05).Conclusion The prevalence of CRE in ICUs is relatively high,with a wide range of bac-terial species.Active screening can improve the detection rate of CRE.

Objective:To investigate the effects and mechanisms of angiotensin-converting enzyme 2 (ACE2) and Captopril (CAP) on mechanical ventilation-induced lung injury (VILI) in mice.Methods:Seventy-two healthy male BALB/c mice were randomly assigned (using a random number table) into six groups ( n=12 per group): normal control (NC) group, VILI group, ACE2 group, VILI+ACE2 group, CAP group, and VILI+CAP group. One hour prior to mechanical ventilation, the ACE2 and VILI+ACE2 groups were intraperitoneally injected with ACE2 at a dose of 0.1 mg/kg, while the CAP and VILI+CAP groups were intraperitoneally injected with CAP at a dose of 2.5 mg/kg. Following mechanical ventilation, serum samples were collected and enzyme-linked immunosorbent assay (ELISA) was used to detect inflammatory factors [platelet activating factor (PAF), endothelin-1 (ET-1), soluble intercellular adhesion molecule-1 (sICAM-1), prostaglandin E2 (PGE2)] and cardiovascular system related indicators [von Willebrand factor (vWF), thrombomodulin (TM), angiotensin (Ang) (1-9), Ang (1-7), prostacyclin I 2 (PGI2)]. Bronchoalveolar lavage fluid (BALF) was gathered, and total protein concentration was determined using BCA method, and sICAM-1 levels were measured by ELISA. Lung tissues were collected and subjected to hematoxylin and eosin staining (HE staining) for the assessment of pathological lung injury and lung injury scoring. Western blot and reverse transcription quantitative polymerase chain reaction (RT-qPCR) were utilized to detect the relative expression levels of ACE2 protein and mRNA, respectively. Statistical analysis was performed using IBM SPSS 20.0 software. Intergroup comparisons were conducted using one-way analysis of variance followed by the least significant difference (LSD) test. Results:No statistically significant differences were observed in the levels of PAF, ET-1, sICAM-1, vWF, TM, Ang(1-9), Ang(1-7), and PGI2 in serum and lung tissues between the ACE2/CAP groups and the NC group (all P>0.05). Compared with the VILI group, the VILI+ACE2 and VILI+CAP groups exhibited significantly decreased serum and lung tissue levels of PAF, ET-1, sICAM-1, and vWF (all P<0.05), while the levels of TM, Ang(1-9), Ang(1-7), and PGI2 were significantly increased (all P<0.05). Pathological lung injury was alleviated, and the lung wet/dry weight ratio was significantly reduced (all P<0.05) in the VILI+ACE2 and VILI+CAP groups. Furthermore, both ACE2 protein and mRNA expression levels were significantly increased in these groups (all P<0.05). Conclusion:Both ACE2 and CAP can inhibit inflammation and protect the cardiovascular system, possibly by promoting the ACE2/Ang(1-9)/Ang(1-7) axis, thereby exerting a protective effect against VILI.

Objective:To summarize and analyze the risk factors associated with bronchial mucus plugs (BMPs) in children with Mycoplasma pneumoniae pneumonia (MPP),providing a clinical basis for the indication of bronchoscopy in children with MPP.Methods:A total of 72 children with MPP admitted to the Department of Pediatrics at the Fourth Affiliated Hospital of Nanjing Medical University from December 2022 to December 2024,who underwent bronchoscopy,were selected for this study.According to the presence or absence of BMPs under tracheoscopy,the patients were divided into the mucus plug group and the non-mucus plug group,and their clinical data were analyzed and compared.Results:Among the 72 children with MPP,30 cases (41.7%) were in the mucus plug group,while 42 cases (58.3%) were in the non-mucus plug group.Univariate Logistic regression analysis showed that thermal peak ( OR 2.086,95% CI 1.029-4.299, P=0.041),thermal duration ( OR 1.453,95% CI 1.197-1.763, P < 0.001),thermal duration ≥10 days ( OR 26.154,95% CI 5.316-128.661, P<0.001),combined with pleural effusion ( OR 4.727,95% CI 1.136-19.677, P=0.033),atelectasis ( OR 5.636,95% CI 2.024-15.699, P<0.001),lymphocyte proportion( OR 0.936,95% CI 0.888-0.978, P=0.014),neutrophil proportion( OR 1.048,95% CI 1.005-1.093, P=0.028),lactatedehydrogenase ( OR 1.005,95% CI 1.001-1.009, P = 0.028),D-dimer ( OR 2.203,95% CI 1.133-4.280, P = 0.020),fibrin degradation products ( OR 1.563,95% CI 1.095-2.231, P=0.014),and no heat regression within 72 hours of hormone use ( OR 0.239,95% CI 0.085-0.667, P=0.006) were significant influencing factors for the formation of BMPs in children with MPP.Multivariate Logistic regression analysis showed that thermal duration ≥10 days and atelectasis were independent risk factors for BMPs formation ( P<0.05). Conclusion:For MPP children with thermal duration≥10 days,especially with atelectasis,BMPs may have been formed,and it is recommended to perform bronchoscopy as soon as possible.
