Objective:To investigate the promoting effect of individualized instruction combined with a blended learning model (IIBLM) in continuing training of neurology.Methods:A total of 93 trainees who received continuing training in Department of Neurology, The First Affiliated Hospital of Sun Yat-sen University, from August 2022 to December 2024 were enrolled as subjects. The 50 trainees registered since January 2024 were enrolled as observation group and received IIBLM teaching, including sub-specialty modular training, a cycle-adaptive cultivation system, a "mutual-selection" mentorship program, an on/off-line dual-track curriculum system, a dynamic course allocation mechanism based on "mutual selection", and a competency growth evaluation system, while the 43 trainees registered before January 2024 were enrolled as control group and received traditional teaching. A questionnaire survey and comprehensive competency assessments were performed to evaluate the effect of teaching, and the t-test, the chi-square test, and the qualitative analysis were used for statistical analysis. Results:Compared with the control group, the experimental group showed systematic improvements in clinical contents, theoretical curriculum, faculty competency, and workflow arrangement during continuing training, with a significant difference in the score of workflow arrangement between the two groups [(9.58±0.67) vs. (9.07±1.44), t=-2.13, P=0.037]. The observation group had a score of (97.70±1.30) for dynamic course allocation, an overall satisfaction rate of 97.15%, and a course benefit rate of 97.55%. The qualitative analysis showed that the trainees in the control group mainly complained of course monotony, while those in the observation group expected to enhance interdisciplinary integration and the cultivation of scientific research abilities. In addition, the results of competency assessment showed a continuous improvement in teaching effect after reform, with no significant difference. Conclusions:IIBLM teaching effectively enhances professional qualities, clinical competency, and the degree of satisfaction with courses among the trainees receiving continuing training, and it also revealed the necessity of interdisciplinary collaborative teaching and the integration of research and clinical practice.

Turning to critical illness is a common stage of various diseases and injuries before death. Patients usually have complex health conditions, while the treatment process involves a wide range of content, along with high requirements for doctor′s professionalism and multi-specialty teamwork, as well as a great demand for time-sensitive treatments. However, this is not matched with critical care professionals and the current state of medical care in China. Telemedicine, which shortens the distance of medical professionals and the gap of disease diagnosis and treatments in various regions through electronic information, can effectively solve the current problem. Therefore, there is an urgent need to develop a standardized, high-quality visualization telemedicine round system .Therefore, experts have been organized to search domestic and foreign literature on telemedicine round for critically ill patients and to form this consensus based on clinical experiences so as to further improve the level of critical care treatments in regions.

Objective:To explore the effects of diversified teaching combined with the affective-cognitive theory in neurology clerkship instruction.Methods:We enrolled 406 medical students on clerkship at the affiliated hospitals of Sun Yat-sen University from November 2023 to April 2024. They were randomly assigned by cluster to either observation group ( n=164) or control group ( n=242). The observation group received a diversified teaching model that selected context-appropriate teaching methods based on clinical scenarios, while using the affective-cognitive theory to optimize instructional pathways. The control group received traditional teaching. The effectiveness of teaching was evaluated through an objective structured clinical examination (OSCE; maximum score, 10 points) and a questionnaire survey. SPSS 22.0 was used to perform Mann-Whitney U test, chi-square test, and multiple linear regression analysis. NVivo 12.0 was employed to process open-ended questions. Results:In the OSCE, the observation group had a significantly higher mean score than the control group [9 (8, 10) points vs. 8 (7, 9) points, Z=-6.10, P<0.001]. The distribution difference across different score ranges between the two groups was also statistically significant ( Z=-5.94, P<0.001). Stratified analyses by sex and neurological theory test score demonstrated significantly higher mean scores in the observation group than in the control group ( P<0.001). The multiple linear regression analysis indicated an independent positive correlation between the novel teaching model and OSCE score ( P<0.001). The results of the questionnaires revealed that in the observation group, 98.57% reported that they were satisfied with the teaching model, and 90.72% reported that they accomplished the core teaching objectives; core competencies including knowledge and skills, communication and collaboration, and professionalism were improved; additionally, the participants of the observational group highly endorsed the practical content, the logical structure and richness of instruction, and the active classroom learning environment. Conclusions:The diversified teaching model integrated with the affective-cognitive theory significantly improves proficiency in core clinical skills across different groups of neurology clerks.

Objective: To explore the relationship between sedentary behavior with cardiorespiratory fitness and executive function in adolescents, and to provide some references for sedentary behavior prevention and executive function improvement. Methods: From September to December 2022, a total of 5 018 adolescents aged 13 to 18 years were selected by stratified random sampling method in Shanghai, Suzhou, Taiyuan,Wuyuan, Xingyi, and Urumqi to conduct physical activity survey, as well as cardiorespiratory fitness and executive function assessment. Pearson s correlation was used to analyze the relationship between sedentary behavior, cardiorespiratory fitness and executive function. The mediation effect model was fitted by the bootstrap mediation procedure in the PROCESS (version 3.3 ) SPSS macro compiled by Haves, and the mediation effect of adolescents cardiorespiratory fitness in the relationship between static behavior and executive function was examined using model 4 in the PROCESS SPSS macro, where Boosrap method was used to compute the mediation effect of adolescents cardiorespiratory fitness. where the Boosrap method was used to calculate confidence intervals for the mediating effects. Results: Adolescents daily sedentary time was positively correlated with both the refreshing function (1-back and 2-back) and the switch function reaction time ( r =0.05, 0.07, 0.05, P <0.01). Adolescent VO 2max was negatively correlated with both the refreshing function (1-back,2-back) and the switching function ( r =-0.09, -0.14 , -0.11, P <0.01). Adolescents daily sedentary time was negatively correlated with VO 2max ( r =-0.04, P <0.01); cardiorespiratory fitness mediated effect values between sedentary behavior and refreshing function (1-back and 2-back) and converted function were 0.20(95% CI =0.06-0.36), 0.43(95% CI =0.14-0.74) and 0.13 (95% CI =0.04-0.22), with mediating effect shares of 6.87%, 8.33% and 8.59%, respectively. Conclusion The duration of sedentary behavior in adolescents is related to executive function performance, and cardiorespiratory fitness may serve as a mediator to mediate the association between sedentary behavior and executive function in adolescents.

Objective: To explore effects of aquatic exercise on lipid metabolism, body composition and peripheral blood Irisin level in obese middle school students, so as to provide reference for exercise and weight loss practice of obese children and adolescents. Methods: Twenty six male students, recruited to participate in the summer youth swimming(weight loss) camp in Rudong County Jiangsu Province, were divided into non obese( n =12) and obese ( n =14) group. And t test method was applied for a statistical analysis of their ipid metabolism, body composition and peripheral blood irisin level before and after 8 week aquatic exercise. Results: The high density lipoprotein cholesferol(HDL-C) in the obese group was significantly lower than nonobese group, which were (1.34±0.12) mmol/L and (1.51±0.21) ng/mL, respectively, and the differences were of statistical significance( t=2.81, 6.39 , 8.96, 12.69, -2.72 , P <0.05). After intervention, body weight, body mass index (BMI), fat mass(FM), body fat percentage(BF%) of obese male middle school students decreased from (77.31±8.26)kg, (28.02±1.67)kg/m 2, (25.16±3.59)kg and (32.65±3.90)% to (72.37±7.19)kg, (26.15±1.21)kg/m 2, (21.71±2.66)kg and (30.14±3.61)%，muscle mass(MM) increased from (25.09±3.41)kg to (26.76±3.55)kg. TC, TG, LDL-C contents decreased from (4.69±0.48, 1.31±0.26, 2.74±0.42)mmol/L to (4.28±0.42, 1.14±0.14, 2.36±0.36)mmol/L, HDL-C increased from (1.34±0.12)mmol/L to (1.47±0.11)mmol/L, and serum Irisin concentrations lowered from (192.17±23.27) ng/mL to (164.15±21.69)ng/mL of obese male middle school students. Serum Irisin concentrations of the obese positively related to BMI( r =0.68), FM( r =0.87) and BF( r =0.64), as well as TC( r =0.61), TG( r =0.86), LDL-C( r =0.85), but negatively associated with HDL-C( r =-0.63). A positive relations existed between different value of serum Irisin concentrations and BMI, FM before and after intervention of obese students( r =0.58, 0.53)( P <0.05). Conclusion Obese middle school students may be resistant to Irisin. 8 weeks of aquatic exercise can improve fat metabolism, body composition and serum Irisin levels of obese junior middle school students effectively. The qualified obese children and adolescents can use aquatic exercise as an intervention measure to control body weight reasonably and improve lipid metabolism.

To establish the experts consensus on the management of delirium in critically ill patients.A special committee was set up by 15 experts from the Chinese Critical Hypothermia-Sedation Therapy Study Group.Each statement was assessed based on the GRADE (Grading of Recommendations Assessment,Development,and Evaluation) principle.Then the Delphi method was adopted by 36 experts to reassess all the statements.(1) Delirium is not only a mental change,but also a clinical syndrome with multiple pathophysiological changes.(2) Delirium is a form of disturbance of consciousness and a manifestation of abnormal brain function.(3) Pain is a common cause of delirium in critically ill patients.Analgesia can reduce the occurrence and development of delirium.(4) Anxiety or depression are important factors for delirium in critically ill patients.(5) The correlation between sedative and analgesic drugs and delirium is uncertain.(6) Pay attention to the relationship between delirium and withdrawal reactions.(7) Pay attention to the relationship between delirium and drug dependence/ withdrawal reactions.(8) Sleep disruption can induce delirium.(9) We should be vigilant against potential risk factors for persistent or recurrent delirium.(10) Critically illness related delirium can affect the diagnosis and treatment of primary diseases,and can also be alleviated with the improvement of primary diseases.(11) Acute change of consciousness and attention deficit are necessary for delirium diagnosis.(12) The combined assessment of confusion assessment method for the intensive care unit and intensive care delirium screening checklist can improve the sensitivity of delirium,especially subclinical delirium.(13) Early identification and intervention of subclinical delirium can reduce its risk of clinical delirium.(14) Daily assessment is helpful for early detection of delirium.(15) Hopoactive delirium and mixed delirium are common and should be emphasized.(16) Delirium may be accompanied by changes in electroencephalogram.Bedside electroencephalogram monitoring should be used in the ICU if conditions warrant.(17) Pay attention to differential diagnosis of delirium and dementia/depression.(18) Pay attention to the role of rapid delirium screening method in delirium management.(19) Assessment of the severity of delirium is an essential part of the diagnosis of delirium.(20) The key to the management of delirium is etiological treatment.(21) Improving environmental factors and making patient comfort can help reduce delirium.(22) Early exercise can reduce the incidence of delirium and shorten the duration of delirium.(23) Communication with patients should be emphasized and strengthened.Family members participation can help reduce the incidence of delirium and promote the recovery of delirium.(24) Pay attention to the role of sleep management in the prevention and treatment of delirium.(25) Dexmedetomidine can shorten the duration of hyperactive delirium or prevent delirium.(26) When using antipsychotics to treat delirium,we should be alert to its effect on the heart rhythm.(27) Delirium management should pay attention to brain functional exercise.(28) Compared with non-critically illness related delirium,the relief of critically illness related delirium will not accomplished at one stroke.(29) Multiple management strategies such as ABCDEF,eCASH and ESCAPE are helpful to prevent and treat delirium and improve the prognosis of critically ill patients.(30) Shortening the duration of delirium can reduce the occurrence of long-term cognitive impairment.(31) Multidisciplinary cooperation and continuous quality improvement can improve delirium management.Consensus can promote delirium management in critically ill patients,optimize analgesia and sedation therapy,and even affect prognosis.

Objective To explore the feasibility of reducing the tube voltage to 80 kV,while ensuring the CT image quality for the diagnosis when the patients with high BMI (26 kg/m2≤BMI≤30 kg/m2)undergo coronary CTA examination,using low concentration isotonic contrast medium (270 mg I/mL)and iterative reconstruction techniques (SAFIRE-3).Methods Sixty patients with high BMI who underwent coronary CTA were randomly divided into group A and group B.Group A was set as"double low"group (n=30,tube voltage=80 kV),using SAFIRE-3 technology and 270 mg I/mL contrast agent.Group B was set as conventional group (n=30,tube voltage=120 kV),using filtered back projection (FBP)technology and 350 mg I/mL contrast agent.Adaptive cardio-sequence prospective ECG-gated technology (CorAdSeq)was applied in both groups,and the collecting phase was 65%-75% R-R interval (heart rate <75 beats per minute)or 40%-50% R-R interval(heart rate ≥75 beats per minute).Subjective and objective assessment methods were applied to evaluate the quality of images.The image quality and radiation dose of"double low"group was analyzed with conventional group as the control group.SPSS 1 9.0 software was applied for statistical analysis.The independent samples t-test was used to evaluate the differences among different measurements data.P<0.05 was considered statistically significant.Results The EDssde of group A [(1.124±0.314)mGy·cm]was significantly lower than that of group B [(3.542±0.797)mGy·cm],and the difference was statistically significant(P<0.001).The difference in noise between group A and B was statistically significant(P<0.05). The SNR and CNR in the group A were not lower than those in the group B and even the CNR in the partial coronary segment of the group A was higher than that in the group B,exhibiting statistically significant difference(P<0.05).Image quality index in the group A was higher than that in group B,and the difference was statistically significant (P<0.05).Conclusion Compared with conventional coronary CTA examination,"double low"coronary CTA examination in patients with high BMI (26 kg/m2≤BMI≤30 kg/m2)can acquire nice CT images suitable for clinical diagnosis and can significantly reduce the radiation dose and the amount of contrast agent.
