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 evaluatethe therapeutic efficacy and underlying mechanism of sodium houttuyfonate in treating airway inflammation in allergic asthma induced by co-exposure to the environmental pollutant benzo[a] pyrene (BaP) and ovalbumin (OVA).Methods:Thirty BALB/c mice were randomly divided into five groups with six mice in each group using a block randomization method: control, BaP, asthma model (OVA), BaP-exacerbated asthma (BaP+ OVA), and sodium houttuyfonate-treated BaP-exacerbated asthma (BaP+ OVA+ SH) groups. A mouse model of exacerbated asthma induced by co-exposure to BaP and OVA was established. Airway hyperresponsiveness, leukocyte distribution in bronchoalveolar lavage fluid (BALF), expression of cytokines such as IL-4, IL-13, IL-25, IL-33, thymic stromal lymphopoietin (TSLP) and IFN-γ, serum OVA-specific antibodies (IgE, IgG2a and IgG1), levels of malondialdehyde and superoxide dismutase (SOD) in lung tissues, and histopathological changes in lung tissues were evaluated. Western blot and RT-qPCR were used to detect the protein and mRNA expression levels of suppression of tumorigenicity 2 (ST2), extracellular regulated protein kinases (ERK), and phosphorylated ERK (p-ERK). Statistical analysis was conducted using analysis of variance and other statistical methods.Results:Compared with the BaP+ OVA group, the mice in the BaP+ OVA+ SH group showed significantly reduced airway hyperresponsiveness ( P<0.01), decreased numbers of total leukocytes ( P<0.01), neutrophils ( P<0.05), and lymphocytes ( P<0.01) in BALF, significantly downregulated secretion of IL-4, IL-13, IL-25, IL-33 and TSLP ( P<0.01), and inhibited production of IgE ( P<0.01) and IgG1 ( P<0.05). Additionally, sodium houttuyfonate treatment significantly decreased the malondialdehyde levels in lung tissues of mice with BaP-exacerbated asthma ( P<0.05) and reduced airway inflammatory cell infiltration, mucus secretion, and collagen fiber proliferation. Sodium houttuyfonate could supress the expression of ST2 and ERK ( P<0.05), inhibit ERK phosphorylation ( P<0.01), alleviate oxidative stress injury, and reduce collagen fiber proliferation in mouse lung tissues, thereby blocking the progression of BaP-exacerbated asthmatic inflammation. Conclusions:BaP exacerbates OVA-sensitized asthmatic airway inflammation in mice by inducing airway remodeling through the IL-33-ST2/ERK pathway. Sodium houttuyfonate inhibits this pathway, thereby preventing the progression of BaP-exacerbated asthma inflammation. This study provides new insights into the prevention and treatment of different phenotypes of asthma.

Objective:To investigate the application value of major anatomical structure recognition model of minimally invasive liver resection based on deep learning.Methods:The retrospective and descriptive study was conducted. The 31 surgical videos of laparoscopic left lateral sectionectomy performed in Zhujiang Hospital of Southern Medical University from January 2019 to April 2023 were collected. Video clips containing the surgical procedure of left lateral lobe liver pedicle and left hepatic vein were screened by 2 liver surgeons. After quality control, screening and frame extraction, the major anatomical structures on the images of these clips were annotated. After pre-processing, these images were transported to the DeepLab v3+neural network framework for model training. Observation indicators: (1) video annotation and classification; (2) results of arti-ficial intelligence anatomical recognition model testing. Measurement data with normal distribution were represented as Mean± SD, and count data were described as absolute numbers. Results:(1) Video annotation and classification. A total of 4 130 frames of images were annotated in the 31 surgical videos, including 2 083 frames of annotated images for the left lateral lobe liver pedicle, 1 578 frames of annotated images for the left hepatic vein and 469 frames of annotated images for both the left lateral lobe liver pedicle and left hepatic vein. (2) Results of artificial intelligence anatomical recognition model testing. In four application scenarios (clean scene, bloodstain scene, partially obstruction by instrument scene, and small exposed area scene), the model was able to successfully recognize the left lateral lobe liver pedicle and left hepatic vein, with a recognition speed for anatomical markers >13 frames/s. When performing anatomical recognition on images with only the left lateral lobe liver pedicle, the Dice coefficient, intersection over union, accuracy, sensitivity and specificity of the model were 0.710±0.110, 0.560±0.120, 0.980±0.010, 0.640±0.030, and 0.980±0.010, respectively. The above indicators of the model were 0.670±0.180, 0.530±0.200, 0.980±0.010, 0.600±0.040, and 0.990±0.010 when performing anatomical recognition on images with only the left hepatic vein, and 0.580±0.180, 0.430±0.190, 0.980±0.010, 0.580±0.020, and 0.990±0.010 when per-forming anatomical recognition on images with both the left lateral lobe liver pedicle and left hepatic vein.Conclusion:The major anatomical structure recognition model of minimally invasive liver resection based on deep learning can be applied in identifying liver pedicle and hepatic vein.
