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 investigate the karyotypes and the correlation of chromosomal abnormalities in the fetuses with increased nu-chal translucency(NT),so as to provide a basis for prenatal genetic counseling.Methods The clinical data of 386 singleton pregnant women with NT≥2.5mm who underwent invasive prenatal diagnosis at the First Affiliated Hospital of Nanjing Medical University from January 2018 to April 2022 were retrospectively analyzed.The fetuses were grouped according to NT thickness(2.5-3.4,3.5-3.9,4.0-4.9,5.0-5.9,and ≥6.0 mm),fetal ultrasound abnormalities(isolated increased NT,non-isolated increased NT),and maternal age(advanced age ≥35 years,non-advanced age＜35 years).The chi-square test was used to compare the differences of the incidence of fetal chromosomal abnormalities among various groups.Results Among the 386 fetuses with increased NT,chromosomal abnormalities were detected in 87 cases with an overall detection rate of 22.5％(87/386),including chromosomal numerical abnormalities accounted for 82.8％(72/87)and copy number variations(CNVs)accounted for 17.2％(15/87).The detection rates of chromosomal abnormal-ities and numerical abnormalities increased with NT thickness(P＜0.05),while no statistically significant difference of CNV abnormali-ty rates was found(P=0.41).The detection rates of chromosomal abnormalities(36.5％)and CNV abnormalities(14.1％)in the non-isolated increased NT group were significantly higher than those in the isolated increased NT group(18.6％and 1.0％,respective-ly,both P＜0.05).The detection rates of chromosomal abnormalities(34.7％)and numerical abnormalities(31.6％)in the fetuses of advanced maternal age mothers with increased NT were significantly higher than those in the non-advanced age group(18.4％and 14.2％,respectively,both P＜0.05).However,the difference of CNV abnormality rates between the two groups was not statistically sig-nificant(P=0.62).Conclusion The detection rate of fetal chromosomal abnormalities elevated with increased NT thickness.Ad-vanced maternal age and the presence of other ultrasound abnormalities were the high-risk factors for fetal chromosomal abnormalities.The risks of CNV abnormalities may not be significantly correlated with NT thickness or maternal age but associated with the presence of other ultrasound abnormalities.

Naringin is a flavonoid compound with a wide range of biological and pharmacologi-cal activities,which can be used in treating tumor,diabetes,neurodegenerative diseases,cardiovascu-lar diseases,metabolic syndrome,etc.Among them,the application of naringin in cardiovascular diseases has attracted the attention of many re-searchers.This article mainly reviews the role of naringin in cardiovascular disease(regulating blood lipids,anti atherosclerosis,lowering blood pres-sure,inhibiting myocardial hypertrophy,anti myo-cardial infarction,protecting myocardial ischemia/reperfusion injury,reducing myocardial ischemia/reperfusion injury and improving pulmonary arteri-al hypertension),the protective effect on cardiotox-icity,and the signal pathways in cardiovascular dis-ease(PI3K-Akt-mTOR,p-eNOS/p-Akt/p-ERK,miR-126/GSK-3 β/β-Catenin),clinical trials,etc.This pa-per is expected to review the current research sta-tus of naringin in cells and animal models so as to reveal its clinical application prospects and provide reference for further research in related fields.

Objective:To evaluate the characteristics of adult abdominal fat distribution and analyze its influencing factors by energy spectrum CT scan.Methods:The body height, weight, waist circumference, and hip circumference of 105 adults were measured, and the characteristics of abdominal fat distribution were evaluated by energy spectrum CT scan.Results:Compared with non-obese individuals, the contents of abdominal subcutaneous fat, abdominal cavity and liver ectopic fat were higher in obese patients ( P<0.05), and the intramuscular fat (IMAT) content did not increase with the increase of BMI. In middle-aged group, the waist circumference, waist-to-hip ratio (WHR) abdominal cavity area and IMAT content were higher than those in the youth group, and the muscle content of the middle-aged group was lower than that of the youth group, the difference between the two groups was significant ( P<0.05); the male group had higher abdominal cavity area and muscle content than the female group, while the female group had higher the subcutaneous fat area, abdominal subcutaneous fat thickness and erector spinae fat content than the male group, the differences were significant ( P<0.05). Conclusions:The characteristics of abdominal fat distribution of subjects with different BMI, age and gender were different. Therefore, we should pay attention to the individual assessment of ectopic fat distribution in obese patients. Energy spectrum CT can be used as an important approach for the assessment of ectopic fat to provide evidence for developing individualized weight loss programs.

Objective:To study the clinical features of children with Prader-Willi syndrome(PWS).Methods:Eighteen cases of PWS were collected from July 2016 to November 2018 in Shenzhen Maternal and Child Healthcare Hospital, Southern Medical University.The clinical data of children with PWS were analyzed retrospectively.Results:There were 12 males and 6 females in 18 cases with PWS.The diagnosis age ranged from 25 days to 9.5 years old [(3.09±3.02) years old]. Among them, 11 cases were in infancy (≤3 years old) and 7 cases after infancy (>3 years old). The main clinical features of infants with PWS were 11 cases of gonadal dysplasia (100.0%), 11 cases of psychomotor retardation (100.0%), 10 cases of hypotonia (90.1%), 6 cases of feeding difficulty and weak cry (54.5%). After infancy the main clinical features included 7 cases of psychomotor retardation (100.0%), 5 cases of hyperphagia(71.4%), 5 cases of obesity (71.4%), 5 cases of abnormal behavior problems (71.4%) and 4 cases of visual problems (57.1%). The clinical features of all patients throughout the developmental stage were as follows: decreased fetal movement, hypoplasia, neonatal hypotonia, weak cry, feeding difficulty, psychomotor delay, hyperphagia, obesity, abnormal behavior problems, and so on.Conclusions:The clinical features of PWS vary with age.The main clinical features in the infancy are hypotonia, weak cry, difficulty feeding and gonadal dysplasia.After infancy, there are hyperphagia, obesity, behavior and visual problems.And psychomotor retardation is present in the whole developmental stage of children with PWS.Early diagnosis and treatment are important for improving the prognosis of PWS.

Objective To compare the effect and prognosis outcome of open reduction internal fixation and primary arthrodesis in treatment of Lisfranc injuries combined with the first tarsal jointdislocation.Methods A retrospective case control study was conducted on the clinical data with complete follow up data of 126 patients with Lisfranc injuries combined with the first tarsal joint dislocation in nine ankle surgery centers of China from January 2009 to June 2015.There were 76 males (60.3％) and 50 females (39.7％) with an average age of 45.5 years (range,20-87 years).Among the 126 cases,simple dislocation occurred in 41 cases (32.5％),and fracture dislocation in 85 cases (67.5％).The duration from injury to surgery was 11.7 days (range,4-26 days).According to surgery method,the patients were divided into open reduction internal fixation group (n =92) and primary arthrodesis group (n =34).The outcomes were evaluated by American Orthopedic Foot and Ankle Society(AOFAS) score,36-items short form health survey (SF-36),and visual analogue score (VAS).Complications were also followed up.Results All patients were followed up for 18-80 months,with an average of 29.5 months.Primary union was seen in all the patients.At the last follow up,the mean AOFAS midfoot score was (79.4 ± 6.7) points in open reduction and internal fixation group and (85.1 ±8.3) points in primary arthrodesis group (P ＜ 0.05).The mean VAS was (3.1 ± 0.6) points in open reduction and internal fixation group and (2.2± 0.3)points in primary arthrodesis group(P ＜ 0.05).The physiological function of SF-36 was (80.3 ± 5.3) points in open reduction and internal fixation group and (83.5 ± 6.9) points in primary arthrodesis group(P ＞ 0.05).The body pain score of SF-36 was (76.1 ±4.6) points in open reduction and internal fixation group and (84.6 ± 8.7) points in primary arthrodesis group (P ＜ 0.05).In open reduction and internal fixation group,there were five cases (5％) with internal fixator loosening or fracture,16 cases (17％) with redislocation,36 cases (39％) with obvious pain of the middle foot during walking,and eight cases (6％) with tarsal joint traumatic arthritis which was given phase Ⅱ arthrodesis.In primary arthrodesis group,two patients (6％) reported pain due to internal fixation,and the pain was relieved after fixator removal.No re-dislocation,loosening of internal fixation,or traumatic arthritis were found (P ＜ 0.05).Conclusion For Lisfranc injuries combined with first tarsal joint dislocation,primary arthrodesis can stabilize the first tarsal joint and avoid complications or adverse consequences such as redislocation,pain,internal fixation failure,or reoperation.
