ObjectiveTo explore the effect of presentation-assimilation-discussion (PAD) classroom model-based classroom-community collaborative teaching on course of sports rehabilitation therapy under the background of sports-medicine integration. MethodsFrom Febrary, 2024 to June, 2025, a total of 46 undergraduate students majoring in sports rehabilitation (Grade 2022, Capital University of Physical Education and Sports) were randomly divided into control group (n = 23) and experimental group (n = 23). The control group received routine lectures combined with laboratory practice, while the experimental group was taught using a classroom-community collaborative teaching based on PAD classroom structure. The two groups were compared in terms of excellent rate in practical assessment, achievement in higher-order dimensions of Bloom's Taxonomy, real-case rehabilitation scenario transformation ability and teaching satisfaction at the end of the semester. ResultsAt the end of the semester, the excellent rate in practical assessment was 60.87% in the experimental group, higher than 21.74% in the control group (χ² = 7.725, P < 0.05), while the scores in the analyse, evaluation and creation dimensions of Bloom's Taxonomy were significantly higher (t > 8.490, P < 0.001), real-case rehabilitation scenario transformation ability was better (t > 3.873, P < 0.001) and teaching satisfaction was higher (χ² = 8.576, P = 0.003). ConclusionPAD-based classroom-community collaborative teaching can effectively improve practical skills, higher-order cognitive abilities and practical application abilities among students majoring in sports rehabilitation.

ObjectiveTo investigate the effectiveness of teaching pedagogy based on outcome-based education (OBE) and conceive-design-implement-operate (CDIO) model in the teaching of exercise rehabilitation training. MethodsTwenty-seven postgraduate students majoring in exercise rehabilitation training of grade 2024 at Capital University of Physical Education and Sports were randomly divided into control group (n = 13) and experimental group (n = 14). The control group received routine teaching methods, while the experimental group received teaching of OBE-CDIO. After the course, theoretical scores, objective structured clinical examination (OSCE) scores and teaching satisfaction via questionnaire were compared between two groups. ResultsAfter the course, there was no significant difference in theoretical scores between two groups (t = 1.103, P > 0.05). Scores in all stations of OSCE were higher in the experimental group than in the control group (t > 2.181, P < 0.05), as well as the satisfaction scores of learning, enthusiasm, organization, group interaction, individual affinity, workload and examination (|t| > 3.781, P < 0.001). ConclusionThe teaching pedagogy based on the OBE-CDIO model can improve practical competence and teaching satisfaction among postgraduate students majoring in exercise rehabilitation training.

Panretinal photocoagulation(PRP)is the first-line treatment for severe non-proliferative diabetic retinopathy and proliferative diabetic retinopathy(PDR).Its therapeutic efficacy varies due to multiple patient-specific systemic and ocular factors. Despite standardized PRP, some patients fail to show adequate regression of neovascularization and subsequently develop vitreous hemorrhage(VH). In such cases, pars plana vitrectomy(PPV)effectively clears the hemorrhage, restores transparency of the ocular media, supplement PRP, and delays the progression of PDR, thus becoming a critical intervention. With recent advances in surgical techniques, concepts, and equipment, early PPV intervention for VH following PRP has emerged as a growing research focus. Nevertheless, consensus remains lacking regarding its indications, optimal timing, and surgical protocols. This article systematically reviews relevant domestic and international studies, summarizing the surgical timing, approaches, and prognoses of PPV for VH in PDR patients after PRP, aiming to provide evidence-based reference for clinical decision-making and reduce the risk of PDR-related blindness.

ObjectiveTo analyze the distribution characteristics of competency structures in master's training programs in sports rehabilitation at Chinese universities based on the rehabilitation competency framework (RCF). MethodsUsing RCF as the theoretical analytical framework, master's training programs from Chinese universities offering sports rehabilitation programs or related training tracks were selected as study objects. A combination of text analysis and competency mapping was employed to conduct a systematic comparative analysis of training objectives, curriculum systems and training components. ResultsA total of 16 master's training programs in sports rehabilitation were included. Research-related competencies were well covered across the included programs, whereas competencies related to practice, and management and leadership were relatively insufficient. These competencies were often presented in fragmented or subsidiary forms and lacked systematic alignment with curriculum objectives and assessment mechanisms. In addition, insufficient coordination between curriculum systems and training components was observed. ConclusionThe current master's training programs in sports rehabilitation exhibit a certain degree of imbalance in their competency structure. This imbalance is mainly manifested in the insufficient and unsystematic integration of practice-related competencies as well as management and leadership competencies across training objectives, curriculum design, and assessment components. RCF enables a diagnostic analysis of the alignment between training elements and competency dimensions, allowing for the clear identification of structural gaps and biases within existing training systems. Consequently, it provides an explicit reference framework for practice-oriented curriculum reconstruction and the optimization of competency-based assessment mechanisms.

Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.

Objective:To establish a standardized code database of adverse drug reactions (ADRs) terms related to linezolid and analyze the common ADRs of linezolid.Methods:Linezolid drug labels, websites (including Side Effect Resource, and the official websites of US Food and Drug Administration, European Medicines Agency and National Medical Products Administration) and scientific literature database (including CNKI, Wanfang, VIP, PubMed, Embase and Web of Science databases) were systematically searched, and ADR terms about linezolid were collected. ADR terms were mapped to the international classification of diseases-10 (ICD-10) code to establish a linezolid adverse reaction database.Results:A total of 117 ADR terms about linezolid were collected and 91 ICD-10 codes were obtained after being mapped to ICD-10. A standardized database was constructed and successfully embedded into the ADR spontaneous reporting system as a specific drug submodule. The gastrointestinal system, skin and subcutaneous tissue system, various nervous systems, blood and lymphatic systems were the most common system organs involved in linezolid-related ADRs under the 91 ICD-10 codes. Among them, ADRs under the gastrointestinal system codes K14.302 (black hairy tongue) and K52.104 (drug-induced gastroenteritis and colitis), the skin and subcutaneous tissue system code L27.005 (drug-induced dermatitis), various nervous system codes G90.800 (other disorders of autonomic nervous system), G62.001 (drug-induced polyneuropathy) and G44.400 (drug-induced headache, not elsewhere classified), the blood and lymphatic system codes D69.502 (drug- induced thrombocytopenia) and D70.x02 (drug-induced granulocytopenia), the metabolic and nutritional codes E87.204 (lactic acidosis), as well as the endocrine system code E16.000 (drug-induced hypoglycaemia without coma) had been reported frequently in the scientific literature. In addition, there were 14 ADR terms related to linezolid under 13 ICD-10 codes not recorded in the drug instructions.Conclusions:It is feasible to use ICD-10 code to standardize ADR terms related to linezolid and establish a database. Common ADRs of linezolid include thrombocytopenia, lactic acidosis, neutropenia, black hairy tongue, gastroenteritis/colitis, hypoglycemia, rash, serotonin syndrome, peripheral neuropathy and headache, which should be paid attention to and researched furtherly.

Objective To explore the association between cardiorespiratory fitness and total atherosclerotic burden of brain-and heart-arteries in patients with ischemic stroke.Methods This study retrospectively enrolled consecutive patients with ischemic stroke of the large-artery atherosclerosis or small-artery occlusion subtypes accompanied by cervicocephalic atherosclerosis,who were admitted to the Department of Neurology,Xuanwu Hospital,Capital Medical University,between May 2023 and December 2024.General and clinical data,including age(＜60years,≥60years),sex,admission blood pressure,body mass index,history of hypertension,diabetes mellitus,hyperlipidemia,ischemic stroke,symptomatic coronary artery disease,smoking,alcohol consumption,and medication use(including antiplatelet drugs,anticoagulants,lipid-lowering drugs,antidiabetic drugs,antihypertensive drugs,and β-blockers),characteristics of ischemic stroke(including the duration of onset,ischemic side[left,right,bilateral],and ischemic location[anterior circulation,posterior circulation,bilateral circulation])were collected from all patients enrolled.On the morning after admission,fasting venous blood samples were collected to measure the levels of triglycerides,total cholesterol,low-density lipoprotein cholesterol,high-density lipoprotein cholesterol,fasting blood glucose,glycated hemoglobin,homocysteine,fibrinogen,D-dimer,C-reactive protein,high-sensitivity C-reactive protein,N-terminal pro-B-type natriuretic peptide,creatine kinase-MB,cardiac troponin T,and myoglobin.Transthoracic echocardiography was performed within 7 days after admission to evaluate cardiac function.Left ventricular ejection fraction and cardiac output were recorded,and cardiac index were calculated.Upon admission,neurological impairment,disability,motor function,and balance ability were assessed using the National Institutes of Health stroke scale(NIHSS),modified Rankin scale(mRS),Fugl-Meyer assessment(FMA),and Berg balance scale,respectively.The Saltin-Grimby physical activity level scale was used to evaluate the intensity of habitual physical activity prior to stroke onset.Cardiopulmonary exercise testing was performed within 7 days after admission to assess cardiopulmonary fitness.During the test,peak oxygen uptake(VO2peak),percentage of predicted VO2peak(VO2peak%pred),and metabolic equivalent of task(MET)were recorded.Based on the minimum oxygen uptake required for independent living(15 ml/[kg·min]),VO2peak was classified into low VO2peak(＜15 ml/[kg·min])and high VO2peak(≥15 ml/[kg·min]).With VO2peak%pred＜0.60 as the cutoff,VO2peak%pred was divided into low VO2peak%pred(＜0.60)and high VO2peak%pred(≥0.60).MET were categorized into low MET(＜mean MET)and high MET(≥mean MET)according to the mean value of MET in this study population.Imaging data of cardio-cerebral arteries were obtained by simultaneous CT arteriography within 7 days after admission.Total atherosclerotic burden of brain-and heart-supplying arteries(TAB-BHAs)was used to quantitatively evaluate the overall degree of cardio-cerebral atherosclerosis.And patients were stratified into high TAB-BHAs(≥4 points)and low TAB-BHAs(＜4 points)groups.The differences in general and clinical characteristics,as well as cardiopulmonary fitness indices,were assessed among different groups of TAB-BHAs.Spearman' s correlation was used in the preliminary analysis of the relationship between cardiorespiratory fitness indicators and TAB-BHAs.Multivariate Logistic regression was conducted with VO2peak,low VO2peak%pred,and low METs as independent variables,and high TAB-BHAs as the dependent variable to assess the association between cardiopulmonary fitness and TAB-BHAs.Covariates were selected through regressions stratified by age≥60 years,male,the least absolute shrinkage and selection operator(LASSO),and the variables exhibit statistically significant differences between the low and high TAB-BHAs groups,respectively.Results A total of 104 patients with ischemic stroke were enrolled.Among all patients enrolled,60patients(with ages ranging from 30 to 72years and a mean age of[54±11]years)met the inclusion and exclusion criteria,and were ultimately included.Amid the 60 patients,52 were male and 8 were female.There were 20 patients(33.3%)with low VO2peak,28 patients(46.7%)with low VO2peak%pred,and 31 patients(51.7%)with low MET(MET＜5.0).45 patients were classified into the low TAB-BHAs group and 15 into the high TAB-BHAs group.(1)Compared with the low TAB-BHAs group,patients in the high TAB-BHAs group were significantly older and had a higher proportion of patients aged≥60 years,they also showed significantly higher fibrinogen levels and a history of antihypertensive drug use(all P＜0.05).No significant differences were observed in other general or clinical characteristics between the two groups(all P＞0.05).Regarding cardiopulmonary fitness parameters,patients in the high TAB-BHAs group had lower VO2peak and MET levels,and higher proportions of patients with low VO2peak,low VO2peak%pred,and low MET compared with those in the low TAB-BHAs group(all P＜0.05).(2)Based on the Spearman's correlation analysis,VO2peak(r=-0.298,P=0.021),VO2peak%pred(r=-0.305,P=0.018),MET(r=-0.303,P=0.018)all exhibited negative correlations between and TAB-BHAs.(3)LASSO regression was used to identify the most pertinent variables for high TAB-BHAs,including low VO2peak,low VO2peak%pred,and fibrinogen.Multivariate Logistic regression analysis was then performed with low VO2peak,low VO2peak%pred,and low MET as independent variables and high TAB-BHAs as the dependent variable.The results showed that after adjusting for age≥60 years,male,and fibrinogen,both low VO2peak(adjusted OR,4.420,95%CI 1.052-18.573,P=0.042)and low VO2peak%pred(adjusted OR,7.423,95%CI 1.411-39.046,P=0.018)were independently associated with high TAB-BHAs in ischemic stroke patients.After further adjusting for variables that differed among high and low TAB-BHAs groups(including age≥60 years,male,fibrinogen,and history of using antihypertensive drugs),multivariate Logistic regression showed that low VO2peak%pred remained independently associated with high TAB-BHAs in ischemic stroke patients(adjusted OR,6.347,95%CI 1.170-34.418,P=0.032).Conclusion Poor cardiopulmonary fitness might be associated with high degree of overall cardio-cerebral atherosclerosis,suggesting cardiorespiratory fitness as a potential correlated indicator that could provide clues for improving early screening of patients with heavy cardio-cerebral atherosclerotic burden and for exploring the underlying mechanisms.

Objective:To explore the clinical characteristics of neonatal necrotizing enterocolitis（NEC）and analyze the risk factors for early-onset NEC.Methods:A total of 220 children with NEC admitted to the Department of Pediatrics，Tianjin Medical University General Hospital from January 1st，2018 to February 29th，2024 were retrospectively selected as the research objects. According to the time of onset，the early-onset group（ n=120）and the late-onset group（ n=100）were established，and the clinical characteristics of the two groups were compared. Another 150 cases of normal healthy newborns born in this hospital in the same period were selected as the control group，and the clinical data of the control group were collected. The clinical characteristics of the early-onset group and the control group were compared，and the risk factors of early-onset NEC were analyzed by multivariate Logistic regression. Results:Compared with the late-onset group，the early-onset group had fever［50.0%（60/120）vs. 40%（40/100）， χ2=7.333， P=0.007］，apnea［39.17%（47/120）vs. 28%（28/100）， χ2=7.568， P=0.006］，no rise in body temperature［56.67%（68/120）vs. 39%（39/100）， χ2=6.815， P=0.009］，abdominal distension［25%（30/120）vs. 40%（40/100）， χ2=13.200， P<0.001］，vomiting［30.83%（37/120）vs. 45%（45/100）， χ2=12.797， P<0.001］was significantly different（all P<0.05）；Multivariate Logistic regression analysis：weight<1 500 g（ OR=5.871，95% CI：3.153～9.673， P<0.001），gestational age<30 weeks（ OR=4.256，95% CI：2.641～7.896， P=0.007），hemodynamically significant patent ductus arteriosus（hs-PDA）（ OR=3.113，95% CI：1.865～5.133， P=0.033），severe anemia（ OR=3.057，95% CI：2.165～4.802， P=0.001），feeding intolerance（ OR=4.215，95% CI：1.579～10.802， P=0.005），amniotic fluid pollution（ OR=2.452，95% CI：1.579～3.111， P<0.001）were the independent risk factors for early-onset NEC（all P<0.05）. Conclusion:Weight<1 500 g，gestational age<30 weeks，hs-PDA，severe anemia，feeding intolerance，and amniotic fluid contamination are independent risk factors for early-onset NEC. In clinical practice，more attention should be paid to these factors for disease prevention，early identification，and timely intervention in newborns to reduce the occurrence of NEC.
