Objective: To identify the social ecological factors of individual, family, and physical environments for affecting the development of fundamental motor skills (FMS) among overweight and obese children, so as to provide a basis for the future intervention design and policy making. Methods: From March to April 2022, one public primary school was recruited from each of the 4 main urban areas in Shijiazhuang, and a total of 425 children in schools were recruited for data collection including individual, family, physical environmental factors, by using a stratified cluster random sampling approach. Test of Gross Motor Development-Third Edition (TGMD-3) was used to evaluate children s FMS. Hierarchical linear regression model was employed to analysis the associations between the 18 factors for individual, family, and physical environments, and the FMS of overweight and obese children. Results: Individual level including the child s age, gender and sleep duration, and family level including high family economic level, parental support for physical activity, and the physical activity environment surrounding the family and community were consistent predictors of movement skills ( B =0.422, -1.972, 0.014, 0.045, 1.042, 0.827, 1.898), ball skills ( B =0.858, 3.953, 0.013, 0.092, 2.141, 1.173, 1.954), and composite skills ( B =1.305, 1.915, 0.028, 0.142, 3.091, 1.962, 3.879) among overweight and obese children ( P <0.05). Furthermore, child s body mass index (BMI), moderate to vigorous physical activity, perceived motor competence, pleasure of exercise,as well as BMI and physical activity levels of their primary caregiver, were associated with different types of FMS ( P <0.05). Individual, family, and physical environmental factors had moderate to high predictive explanatory power for FMS among overweight and obese children ( 2=0.69, 0.75, 0.93, P <0.01). Conclusions The factors influencing the development of FMS in overweight and obese children are multifaceted, with individual, family, and physical environment factors all playing significant roles.Corresponding measures should be actively taken to improve FMS in overweight and obese children.

Osteoporotic proximal humeral fracture (OPHF) is one of the common osteoporotic fractures in the aged, with an incidence only lower than vertebral compression fracture, hip fracture, and distal radius fracture. OPHF, secondary to osteoporosis and characterized by poor bone quality, comminuted fracture pattern, slow healing, and severely impaired shoulder joint function, poses a big challenge to the current clinical diagnosis and treatment. In the field of diagnosis, treatment, and rehabilitation of OPHF, traditional Chinese and Western medicine have accumulated rich experience and evidence from evidence-based medicine and achieved favorable outcomes. However, there is still a lack of guidance from a relevant consensus as to how to integrate the advantages of the two medical systems and achieve the integrated diagnosis and treatment. To promote the diagnosis and treatment of OPHF with integrated traditional Chinese and Western medicine, relevant experts from Orthopedic Expert Committee of Geriatric Branch of Chinese Association of Gerontology and Geriatrics, Youth Osteoporosis Group of Orthopedic Branch of Chinese Medical Association, Osteoporosis Group of Orthopedic Surgeon Branch of Chinese Medical Doctor Association, and Osteoporosis Committee of Shanghai Association of Integrated Traditional Chinese and Western Medicine have been organized to formulate Expert consensus on the diagnosis and treatment of osteoporotic proximal humeral fracture with integrated traditional Chinese and Western medicine ( version 2024) by searching related literatures and based on the evidences from evidence-based medicine. This consensus consists of 13 recommendations about the diagnosis, treatment and rehabilitation of OPHF with integrated traditional Chinese medicine and Western medicine, aimed at standardizing, systematizing, and personalizing the diagnosis and treatment of OPHF with integrated traditional Chinse and Western medicine to improve the patients ′ function.

Aim To explore the effects of Lycium berry seed oil on Nrf2/ARE pathway and oxidative damage in testis of subacute aging rats. Methods Fifty out of 60 male SD rats, aged 8 weeks, were subcutaneously injected with 125 mg • kg"D-galactosidase in the neck for 8 weeks to establish a subacute senescent rat model. The presence of senescent cells was observed using P-galactosidase ((3-gal), while testicular morphology was examined using HE staining. Serum levels of testosterone (testosterone, T), follicle-stimulating hormone ( follicle stimulating hormone, FSH ) , luteinizing hormone ( luteinizing hormone, LH ) , superoxide dis-mutase ( superoxide dismutase, SOD ) , glutathione ( glutathione, GSH) and malondialdehyde ( malondial-dehyde, MDA) were measured through ELISA, and the expressions of factors related to aging, oxidative damage, and the Nrf2/ARE pathway were assessed via immunohistochemical analysis and Western blotting. Results After successfully identifying the model, the morphology of the testis was improved and the intervention of Lycium seed oil led to a down-regulation in the expression of [3-gal and -yH2AX. The serum levels of SOD, GSH, T, and FSH increased while MDA and LH decreased (P 0. 05) . Additionally, there was an up-regulated expression of Nrf2, GCLC, NQOl, and SOD2 proteins in testicular tissue ( P 0. 05 ) and nuclear expression of Nrf2 in sertoli cells. Conclusion Lycium barbarum seed oil may reduce oxidative damage in testes of subacute senescent rats by activating the Nrf2/ARE signaling pathway.

Objective To investigate the neuroprotective effect of Huangpu Tongqiao Capsule(HPTQ)in a rat model of Wilson disease(WD)and explore the underlying mechanisms.Methods SD rat models of WD were established by feeding of copper-supplemented chow diet and drinking water for 12 weeks,and starting from the 9th week,the rats were treated with low-,moderate-and high-dose HPTQ,penicillamine,or normal saline by gavage on a daily basis for 3 weeks.Copper levels in the liver and 24-h urine of the rats were detected,and their learning and memory abilities were evaluated using Morris water maze test.HE staining was used to observe morphological changes of CA1 region neurons in the hippocampus,and neuronal apoptosis was detected with TUNEL staining.Hippocampal expressions of endoplasmic reticulum stress(ERS)-mediated apoptosis pathway-related proteins GRP78,CHOP,caspase-12,cleaved caspase-9,and cleaved caspase-3 at both the mRNA and protein levels were detected using RT-qPCR,immunofluorescence assay or Western blotting.Results Compared with normal control rats,the rat models with copper overload-induced WD exhibited significantly increased copper levels in both the liver and 24-h urine,impaired learning and memory abilities,obvious hippocampal neuronal damage in the CA1 region and increased TUNEL-positive neurons(P<0.01),with also lowered mRNA and protein expressions of GRP78,CHOP,caspase-12,cleaved caspase-9,and cleaved caspase-3 in the hippocampus(all P<0.01).Treatments with HPTQ and penicillamine significantly lowered copper level in the liver but increased urinary copper level,improved learning and memory ability,alleviated neuronal damage and apoptosis in the hippocampus,and decreased hippocampal expressions of GRP78,CHOP,caspase-12,cleaved caspase-9,and cleaved caspase-3 in the rat models(P<0.01 or 0.05).Conclusion HPTQ Capsule has neuroprotective effects in rat models of WD possibly by inhibiting ERS-mediated apoptosis pathway.

Objective To investigate the safety and feasibility of repeated recanalization of radial artery occlusion(RAO)in neurointerventional therapy.Methods The clinical data,including general information,surgery,ultrasonography,and surgery-related complications,of 18 patients with cerebrovascular diseases,who developed RAO after receiving transradial access(TRA)intervention at the Xiamen Branch of Affiliated Zhongshan Hospital of Fudan University of China between June 2022 and July 2023,were retrospectively analyzed.Results Of 18 patients,7 received two consecutive same-side TRA procedures and 11 received three consecutive same-side TRA procedures.RAO occurred in all patients after the initial cerebrovascular angiography,and subsequent neurointerventional treatment was successfully accomplished after RAO recanalization.The cerebrovascular diseases included arteriovenous malformations(n=3),arterial aneurysm(n=13),and arterial occlusion(n=2).A total of 29 times of puncturing at the site of RAO thrombus were carried out,including 23 times of successful recanalization(success rate being 79.3％).At(8.8±8.7)days after the first-time RAO recanalization,ultrasonography indicated that successful recanalization was obtained in 14 patients and persistent occlusion was seen in 4 patients.Thirteen patients were followed up for(7.8±2.7)months after the initial RAO recanalization,and the ultrasonography revealed that successful recanalization was obtained in 4 patients and persistent occlusion was seen in 9 patients.No severe complications occurred during the follow-up period.Conclusion In situ puncture of the RAO site after its recanalization to perform neurointerventional treatments is clinically safe and feasible.

Purpose::The toughest challenge in pedestrian traffic accident identification lies in ascertaining injury manners. This study aimed to systematically simulate and parameterize 3 types of craniocerebral injury including impact injury, fall injury, and run-over injury, to compare the injury response outcomes of different injury manners.Methods::Based on the total human model for safety (THUMS) and its enhanced human model THUMS-hollow structures, a total of 84 simulations with 3 injury manners, different loading directions, and loading velocities were conducted. Von Mises stress, intracranial pressure, maximum principal strain, cumulative strain damage measure, shear stress, and cranial strain were employed to analyze the injury response of all areas of the brain. To examine the association between injury conditions and injury consequences, correlation analysis, principal component analysis, linear regression, and stepwise linear regression were utilized.Results::There is a significant correlation observed between each criterion of skull and brain injury ( p < 0.01 in all Pearson correlation analysis results). A 2-phase increase of cranio-cerebral stress and strain as impact speed increases. In high-speed impact (> 40 km/h), the Von Mises stress on the skull was with a high possibility exceed the threshold for skull fracture (100 MPa). When falling and making temporal and occipital contact with the ground, the opposite side of the impacted area experiences higher frequency stress concentration than contact at other conditions. Run-over injuries tend to have a more comprehensive craniocerebral injury, with greater overall deformation due to more adequate kinetic energy conduction. The mean value of maximum principal strain of brain and Von Mises stress of cranium at run-over condition are 1.39 and 403.8 MPa, while they were 1.31, 94.11 MPa and 0.64, 120.5 MPa for the impact and fall conditions, respectively. The impact velocity also plays a significant role in craniocerebral injury in impact and fall loading conditions (the p of all F-test < 0.05). A regression equation of the craniocerebral injury manners in pedestrian accidents was established. Conclusion::The study distinguished the craniocerebral injuries caused in different manners, elucidated the biomechanical mechanisms of craniocerebral injury, and provided a biomechanical foundation for the identification of craniocerebral injury in legal contexts.

Objective:To investigate the effects of multidisciplinary small-class teaching on expertise and skill acquisition and learning experience in standardized residency training in general surgery.Methods:Sixty residents of grade 2021 rotating in general surgery from January to August 2023 were divided into multidisciplinary teaching group ( n=30) and traditional teaching group ( n=30, to receive tradition one-on-one teaching). All the residents underwent a theoretical examination and Mini-Clinical Evaluation Exercise (Mini-CEX) skill assessment before admission, and the scores were compared between the two groups. At the end of training, the two groups were compared in terms of theoretical and Mini-CEX skill assessment scores and the degree of satisfaction with teaching. Statistical analysis was conducted using SPSS 26.0. Results:There were no significant differences in the theoretical assessment and Mini-CEX skill assessment scores before admission between the two groups ( P>0.05). At the end of training, the multidisciplinary teaching group had a significantly higher theoretical examination score [(88.15±3.45) vs. (72.25±4.36), P<0.05] and a significantly higher Mini-CEX score [(86.35±2.24) vs. (76.28±3.92), P<0.05] compared with the traditional teaching group. According to the survey, the residents in the multidisciplinary teaching group were more satisfied with teaching and more likely to recognize the teaching effects. Conclusions:Multidisciplinary small-class teaching can help improve the quality of standardized general surgery residency training on gastrointestinal tumor treatment, which is a highly accepted and effective attempt at standardized residency training.

Objective To investigate the incidence rate,clinical characteristics,and prognosis of neonatal stroke in Shenzhen,China.Methods Led by Shenzhen Children's Hospital,the Shenzhen Neonatal Data Collaboration Network organized 21 institutions to collect 36 cases of neonatal stroke from January 2020 to December 2022.The incidence,clinical characteristics,treatment,and prognosis of neonatal stroke in Shenzhen were analyzed.Results The incidence rate of neonatal stroke in 21 hospitals from 2020 to 2022 was 1/15 137,1/6 060,and 1/7 704,respectively.Ischemic stroke accounted for 75％(27/36);boys accounted for 64％(23/36).Among the 36 neonates,31(86％)had disease onset within 3 days after birth,and 19(53％)had convulsion as the initial presentation.Cerebral MRI showed that 22 neonates(61％)had left cerebral infarction and 13(36％)had basal ganglia infarction.Magnetic resonance angiography was performed for 12 neonates,among whom 9(75％)had involvement of the middle cerebral artery.Electroencephalography was performed for 29 neonates,with sharp waves in 21 neonates(72％)and seizures in 10 neonates(34％).Symptomatic/supportive treatment varied across different hospitals.Neonatal Behavioral Neurological Assessment was performed for 12 neonates(33％,12/36),with a mean score of(32±4)points.The prognosis of 27 neonates was followed up to around 12 months of age,with 44％(12/27)of the neonates having a good prognosis.Conclusions Ischemic stroke is the main type of neonatal stroke,often with convulsions as the initial presentation,involvement of the middle cerebral artery,sharp waves on electroencephalography,and a relatively low neurodevelopment score.Symptomatic/supportive treatment is the main treatment method,and some neonates tend to have a poor prognosis.
