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 construct an intervention programme for breastfeeding among mothers of infants with congenital heart disease and to verify its effect.Methods Taking the capability-opportunity-motivation-behaviour model as the theoretical basis,the first draft of the intervention programme was formed through literature search and semi-structured interviews,and 8 experts in the relevant fields were selected to conduct expert validation and determine the content of the program.By the consecutive sampling method,infants and their mothers who attended the cardiothoracic disease clinic of a tertiary-level children's specialist hospital in Shanghai from 4 May to 24 June 2023,with a day-old age of≤14 d and a confirmed diagnosis of CHD,were selected as the study subjects.They were divided into an experimental group and a control group,with 16 cases in each group,by the method of randomized grouping by district.The experimental group received breastfeeding intervention for mothers of infants with CHD on the basis of routine care;the control group received routine care and basic disease education and breastfeeding counselling.At 1 and 3 months of the infants with CHD,the 2 groups were compared in terms of exclusive breastfeeding rate,daily human milk as a percentage of total feeds,weight for age Z-score and height for age Z-score.Results A total of 1 round of expert validation was conducted,with a valid questionnaire recovery rate of 100％and an expert authority coefficient of 0.94.The breastfeeding intervention programme for mothers of infants with CHD is a comprehensive approach that encompasses 3 key dimensions,including capability,opportunity,and motivation.The programme is designed to enhance mothers'ability to recognize feeding signals,master breastfeeding techniques,and maintain successful breastfeeding practices.It also addresses common breastfeeding challenges and provides effective solutions.Additionally,it includes strategies for breastmilk management and fosters family support for breastfeeding.The programme offers medical information support on breastfeeding and aims to elevate mothers'understanding of its benefits.It involves systematic monitoring and recording of breastfeeding volumes,as well as thorough assessments and guidance on infant growth and development,including but not limited to the 10 specific entries related to the infant's progress.The results of the generalized estimating equations and repeated measures analysis of variance revealed statistically significant between-group differences(P＜0.05)in the rates of exclusive breastfeeding,the proportion of daily human milk as a percentage of total feeds,and the weight-for-age(WAZ)and height-for-age(HAZ)z-scores of infants across the 2 groups at various time points.The results of simple effect analysis showed that the differences in exclusive breastfeeding rate,the proportion of daily human milk as a percentage of total feeds,WAZ and HAZ between the 2 groups before intervention were not statistically significant(P＞0.05).At the age of 3 months of the infants after the intervention,the rate of exclusive breastfeeding in the experimental group was higher than that in the control group,and the difference was statistically significant(P=0.003).The proportion of daily human milk as a percentage of total feeds for infants in the intervention group at 1 and 3 months of age was higher than that in the control group,with a statistically significant difference(P＜0.05).At 3 months of age,WAZ of the experimental group was higher than that of the control group,and the difference was statistically significant(P=0.037);HAZ of the experimental group was higher than that of the control group at 1 and 3 months of age after intervention,and the difference was statistically significant(P＜0.05).Conclusion The breastfeeding intervention programme for mothers of infants with CHD,constructed on the basis of the COM-B model in this study,was comprehensive,feasible and acceptable.Implementation of the programme has potential positive effects on increasing exclusive breastfeeding rates and the daily human milk as a percentage of total feeds,and may also have a positive impact on WAZ and HAZ of infants.

Objective:This study aims to analyze the characteristics and basic principles of emergency surgery risks and anesthesia care of medical support at the landing site for China’s taikonauts of the Shenzhou-12, and to summarize China’s experience in medical support at the landing site for manned spaceflight, and ensure supports in special environments such as an emergency return of manned spaceflight.Methods:This study was carried out through literature research on relevant reports on the emergency surgery risks and aids of domestic and foreign astronauts at the landing sites, and summaries of the experience in medical support for taikonauts of spacecrafts from Shenzhou-5 to Shenzhou-11 at the landing sites. At the same time, according to the characteristics of Shenzhou-12 such as the long on-orbit time, the adjustment in the landing area, the optimization of the mission mode, and new search and rescue power, a series of organization, pre-arranged planning, equipment allocation, and effective anesthesia treatment plan were proposed and inspected in practice.Results:Based on the original anesthesia care plan of medical support, the first-aid carrier was adjusted and modified, the first-aid procedure was optimized, a new generation of supraglottic airway opening tool, video laryngoscope, portable ultrasound, and other devices were added, and the anesthesia care plan at the landing site for manned spaceflight was formulated to provide strong support for the medical care of taikonauts that had stayed in the outer space for a long time.Conclusions:Upon the targeted improvement and process optimization, the anesthesia care plan of medical support for taikonauts of Shenzhen-12 in the landing area fully meets the anesthesia requirement of medical support in special environments such as the emergency return of the taikonauts that have stayed in the outer space for a long time under the new orbital altitude.

Neonatal skin care is still an important aspect of newborn care. At present, although there are nursing standards for various types of neonatal skin problems, there are different reports on complete evidence-based neonatal skin care practices. The American Association of Women's Health, Obstetric and Neonatal Nurses (AWHONN) developed and published the fourth edition of the Evidence- based Clinical Practice Guideline for Neonatal Skin Care in 2018. The guideline gives detailed guidance on the assessment of neonatal skin, identification of risk of neonatal skin damage, intervention of neonatal skin care, method of promoting neonatal skin development, and treatment of neonatal skin damage. However, nurses in China know little about this guideline. In order to facilitate nurses' understanding and application of this guideline to guide clinical practice, the content of this guideline is specially interpreted.

OBJECTIVE: To explore the genetic basis for a child featuring delayed intellectual development. METHODS: The child and his parents were subjected to conventional G-banding karyotyping and single nucleotide polymorphism array (SNP-array) analysis. Suspected copy number variations (CNVs) were verified in both parents. RESULTS: No karyotypic abnormality was found with the child and his parents. SNP-array results for both parents were normal. The child was found to harbor a de novo 172 kb deletion at 18q21.2 with a physical position of 52 957 042-53 129 237. The deletion only involved one OMIM gene, namely TCF4, resulting in removal of its exons 6 to 8. CONCLUSION The SNP-array assay has facilitated with the diagnosis of this child. Deletion of 18q21.2 region probably accounts for the Pitt-Hopkins syndrome (PTHS) in this patient.

Objective To explore the genetic basis for a child featuring severe mental retardation.Methods The child was subjected to target region capture and next generation sequencing.Suspected variants were verified by Sanger sequencing.Results The child was found to harbor a hemizygous c.1A＞G (pMet1?) variation of the ARX gene,for which his mother was a heterozygous carrier.The mutation was unreported previously and was predicted to be "probably pathogenic" by bioinformatic analysis.Conclusion The c.1A＞G (pMet1?) variant of the ARX gene may underlie the occurrence of severe mental retardation in this child.

Objective To observe the effect of PIF1 knockdown on cell growth and cell cycle arrest induced by ionizing radiation.Methods HeLa cell lines that consistently down-regulated PIF1 were prepared by the lentivirus granules interfering technology and confirmed by real-time PCR and Western blotting.The effect of down-regulation of PIF1 on cell growth and cell cycle arrest induced by ionizing radiation was evaluated by cell counting and flow cytometry.Results HeLa cell lines consistently down-regulating PIF1 were established.The growth of HeLa that down-regulated PIF1 was inhibited greatly after 4 Gy of γ-ray irradiation.There was little cell proliferation until the 5th day post 4 Gy γ-ray.Moreover, the S phase block and G2/M phase block of PIF1 knock-downed cell lines were significantly delayed after 8 Gy γ-ray irradiation.Conclusion Knockdown of PIF1 can significantly enhance the radiation sensitivity and delayes the S phase block and G 2 /M phase block induced by ionizing radiation.

OBJECTIVETo deepen the understanding of clinical manifestations and treatment of patients with positive lupus anticoagulant (LAC).

METHODSThe clinical data of 2 patients were analyzed and related literature were reviewed.

RESULTSCase 1, a 31-year-old female, diagnosed as lupus anticoagulant positive, secondary to undifferentiated connective tissue disease, was presented with menorrhagia and thrombocytopenia. Anti-nuclear antibody (ANA) was positive 1:1000 (homogeneous type) with anti-double stranded DNA positive, and dRVVT LA1/LA2 was 3.4. Coagulation function was alleviated after treatment with glucocorticoid and total glucosides of paeony. Case 2, a 59-year-old female was presented with gingival bleeding, hematuria with the level of F II:C 13%. dRVVT LA1/LA2 was 2.0. Anti-nuclear antibody (ANA) was positive 1:1000 (type of cytoplasmic granule), anti-double stranded DNA was positive. The patient was diagnosed as hypoprothrombinemia-lupus anticoagulant syndrome (LAHS) and acquired coagulation factor deficiency. The signs of hemorrhage were alleviated after treatment with methylprednisolone 40 mg/day and cyclophosphamide, while the level of F II:C was below normal.

CONCLUSIONSymptoms of patients with positive LAC are variable. The diagnosis relies on history of disease and laboratory test. Currently, there is no standardized treatment. Cases of LAHS should be thoroughly investigated for any known causes and related disorder.

OBJECTIVETo explore the clinical value of the neonatal hearing combined with deafness gene screening.METHODSFrom February 2014 to August 2015, 1933 newborns were included in the study. We analyzed the effects of combined screening of hearing and deafness gene.RESULTSAmong all the 1933 neonates, 71.34% (1379/1933) passed and 28.66% (554/1933) failed the initial hearing screening.The hearing impairment rate was 4.14‰ (8/1933). Genetic screening mutation rate was counted. GJB2 mutation rate was 28.97‰ (56/1933). SLC26A4 mutation rate was 13.97‰ (27/1933). GJB3 mutation rate was 6.21‰ (12/1933). Mitochondrial 12 S rRNA gene mutation rate was 1.03‰ (2/1933). 1 case of 235 delc homozygous mutation did not pass the initial hearing screening and lost to follow-up rescreening. 2 cases of 12 S rRNA 1555A>G homogeneous mutations passed early hearing screening. 8 cases of auditory handicaps were all normal.CONCLUSIONDeafness gene screening can make up for the deficiencies of the universal newborn hearing screening. Joint use of both of them should complement each other and play the biggest role.
