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 compare the preliminary efficacy and nursing care of radioprotective agent skin relief cream and Biafine for the prevention and treatment of neck radiation-induced skin damage in patients with nasopharyngeal carcinoma. Methods: Sixty-seven nasopharyngeal carcinoma patients initially treated with intensity-modulated radiotherapy in Sun Yat-sen University Cancer Prevention and Control Center from 2016 to 2017 were recruited and assigned into the control (n=36) and experimental groups (n=31). In the control group, Biafine was applied to the skin in the radiation field and radioprotective agent skin relief cream was applied in the experimental group. The degree of radiation skin injury and adverse reactions were statistically compared between two groups. Results: No grade IV radiation-induced skin damage occurred in two groups. The incidence rates of grade 1, 2 and 3 radiation-induced skin damage in the experimental group were 45%, 42% and 13%, and 17%, 64% and 19% in the control group, respectively (P=0.04). Radioprotective agent skin relief cream could control the radiation-induced skin injury within grade Ⅱ and significantly increase the proportion of grade I skin injury. Conclusion Medical radioprotective agent is superior to Biafine in the prevention and treatment of radiation-induced skin damage in patients with nasopharyngeal carcinoma.

Objective To investigate the relationships of MR indexes such as acromio humeral intervals (AHI),lateral extension of the acromion (LEA) and inclination angle of the acromion with the subacromial impingement syndrome (SIS).Methods 151 patients underwent MRI examination of shoulder joints,they were grouped according to age,gender and location of acromion.The differences in age,gender and MR indexes were compared between SIS group and non SIS group.The distribution statuses of SIS in different groups were compared at the same time,the relationships of various MR indexes with SIS were investigated and analyzed.Results There were no statistical differences in age,location distribution,the average shortest AHI value and the thickness of the subacromial bursal effusion between SIS group and non SIS group (P ＞ 0.05).There showed statistical difference in gender between the two groups (P =0.000),and there were more males than females in both groups.The acromion exactly covered the supraspinatus tendon in 79 patients,the average value of LEA in the SIS group was greater than that in the non SIS group,and there showed statistically significant difference between the two groups (P =0.002),the Youden index of LEA was 0.40,the sensitivity was 61％ and the specificity was 79％.The inclination angle of the acromion in the SIS group was smaller than that in the non SIS group,and there was a statistically significant difference between the two groups (P =0.019),the Youden index of the inclination angle of the acromion was 0.18,the sensitivity was 62％ and the specificity was 56％.47 patients in the SIS group had subacromial bursal effusion,51 patients in the non SIS group had subacromial bursal effusion.The thickness of the subacromial bursal effusion in the SIS group was greater than the non SIS group,and there showed statistically significant difference between the two groups (P =0.002),the Youden index of the thickness of the subacromial bursal effusion was 0.34,the sensitivity was 78 ％ and the specificity was 56 ％.Conclusion LEA,the inclination angle of the acromion and the thickness of the subacromial bursal effusion can be used as quantitative MR diagnostic criteria of SIS.The LEA measured by cardiothoracic ratio is simple and easy to use.

AIM:To observe the protective effect of Nano-Se on myocardium of experimental diabetes mice.METHODS:Sixty healthy male KM mice were chosen,ten of which were selected randomly as the normal control group.After fasted for 24 h,the rest 50 mice were injected with streptozotocin(STZ,50 mg/kg)intraperitoneally for 5 d.At 7th d,the blood-sugar was measured from vena caudalis,40 mice,of which blood-sugar exceeded 16.65mmol/L,were selected and randomized into 4 groups:the positive control group,low dose(25 ?g/kg)Nano-Se group,mid dose(50 ?g/kg)Nano-Se group,high dose(50 ?g/kg)Nano-Se group.All mice were given intragastric administration of 0.2 mL normal saline and corresponding dose of Nano-Se.The body weights were measured every week,and the dose of which was adjusted according to the change of the body weights.8 weeks later,the mice were killed and cardiac muscle of the left ventricle was taken.The myocardium was prepared to 10% homogenate for measuring SOD,GSH-Px activity and MDA content.The myocardial cell apoptosis was measured by TUNEL.The expressions of Bc1-2 and Bax proteins were determined by immunohistochemistry.RESULTS:Compared to normal group,the SOD and GSH-Px activities in positive control group decreased,MDA level increased,the rate of myocardial cell apoptosis increased significantly,Bc1-2 protein expression deceased and Bax protein expression increased.Compared to positive control group,the SOD and GSH-Px activities in low and mid dose Nano-Se groups expression increased,MDA level decreased,myocardial cell apoptosis rate decreased,Bc1-2 protein expression increased and Bax protein expression decreased.Moreover,the SOD and GSH-Px activities in high dose Nano-Se group decreased obviously compared to those in mid dose Nano-Se group.MDA level and myocardial cell apoptosis rate increased,Bc1-2 protein expression decreased and Bax protein expression increased,no significant difference in SOD,GSH-Px activity,MDA level and myocardial cell apoptosis rate was observed compared with positive control group.CONCLUSION:The damage of cardiac muscle is alleviated when a certain dose of Nano-Se is supplied to diabetes mice.The protective mechanism may be related to antioxidation,blood-sugar adjustment and the increase of Bc1-2 expressing.

Aim To investigate the cardioprotective effects and the possible mechanism of trimetazidine in the risky areas during late reperfusion after acute myocardial infarction in canine.Methods Twenty-four adult dogs were randomized into three groups:sham operation group(n=8),late reperfusion group(LR,n=8),late reperfusion after trimetazidine treatment group(LR+TMZ,n=8).Physiological saline was orally given in the sham operation group and LR group and trimetazidine(2 mg?kg-1?d-1) in the LR+TMZ group for fourteen days.After that later,all chests were opened and coronary areteries were exposed.Exceptly shame operation group,the late reperfusion of acute myocardial infarction model was made by ligating the coronary for 10 h,followed by reperfusion of 10 h.Apoptotic index were detected by TUNEL.The Bcl-2,Bax,Cytochrome C and apoptosis-inducing factor(AIF) proteins were detected by immunohistochemistry.Results Compared with those of LR group,myocardial apoptotic index and the expression of Bax,Cytochrome C and AIF proteins in LR+TMZ decreased significantly(all P
