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 establish a method for isolating alveolar macrophage (AM) of mouse based on flow cy tometry.Methods The lungs were digested by collagen ⅣV in vitro to prepare single-cell suspension that was stained by CD11 b and CD1 1 c antibody.CD1 1 b1owCD1 1 c + cell population were AM and isolated by flow cytometry.After that,the cell viability was measured via the Typan blue staining,and the identification of AM was through flow cytometry and real-time PCR.Results CD1 1 b1owCD1 1 c + cell population was isolated by flow cytometry,the purity was (93 ± 2)％ and the cell viability was (80 ±5)％.The real-time PCR results showed that peroxisome proliferator-activated receptor γ (PPARγ) mRNA was highly expressed in AM isolated by flow cytometry (P ＜ 0.001).In addition,the functional assay showed that the isolated AM possess high phagocytic activity.Thus,the results described above demonstrate that the isolated cells were AM.Conclusion A method for obtaining AM based on flow cytometry was established.The method has high cell purity and good cell activity which can be used for functional experiments.

Objective: To study the clinical effect of high pressure oxygen and Butylphthalide in the recovery of cerebral metabolism after carbon monoxide poisoning. Methods: 84 patients treated from May 2014 to May 2016 in our hospital were selected. The subjects were randomly and equally divided into two groups. The control group adopted the conventional therapy and high pressure oxygen; on the basis, the observation group also took Butylphthalide. The clinical effect, duration of coma, recovery of consciousness, incidence rate of delayed encephalopathy was observed. After 1m of treatment, the HDS point was evaluated. Results: The total effective rate of control group (76.19%, 32/42) was lower than that of observation group (95.24%, 40/42) (P<0.05) . The duration of coma for observation group was shorter than that of control group. The percentage for patients with recovery of consciousness and incidence rate of delayed encephalopathy for observation group was better than that of control group (P<0.05) . The HDS point for observation group was even higher than that of control group (P<0.05) . Conclusion The high pressure oxygen and butylphthalide can improve the clinical effective rate, shorten the duration of coma and promote the patient’s recovery of consciousness. It is worthy of clinical promotion.

Objective To investigate the changes of adhesion molecules and their effects on skeletal muscle ischemia/reperfusion injury. Methods 42 Wistar rats were divided into 3 groups: normal control group (Group Ⅰ, n=6), ischemia group (Group Ⅱ, n=6),ischemia/reperfusion injury group (Group Ⅲ, n=30). The level of malondialdehyde (MDA) in the plasma, myeloperoxidase (MPO) in the skeletal muscle, CD11b/CD18 on the leukocytes, intercelluar adhesion molecule-1 (ICAM-1) in the skeletal muscle and the histological changes were studied 1 h, 2 h, 4 h, 8 h, 12 h reperfusion after ischemia for 4 h. Results In group Ⅲ, the expression of CD11b/CD18, ICAM-1 and the injury of skeletal muscle increased with the lapse of reperfusion time. They reached the peak at 8～12 hours' reperfusion. The injury of skeletal muscle developed with the expression of adhesion molecules. Conclusion The expression of CD11b/CD18 and ICAM-1 are significantly associated with the skeletal muscle ischemia-reperfusion injury.
