Objective:
To explore of executive function in obese adolescents, so as to provide a reference for executive function enhancement intervention in obese adolescents.
Methods:
A convenience sample of 1 227 adolescents aged 13-18 years was selected from 2 secondary schools in Taiyuan City during March-April 2023. The Flanker task, N-back task and More odd shifting task was used to compare the different subfunctions of executive function (refreshing function, shifting function, inhibiting function) of 61 obese adolescents and 70 normal weight adolescents. Independent samples t-tests was used for between group comparisons and Cohen s d -tests was used to calculate between group differences in executive function between the two groups of adolescents.
Results:
Compared with the group of normal weight, time responses of the inhibitory function [(29.73±19.55)ms], the refreshing function [1-back: (1 088.75±275.76)ms, 2-back:( 1 285.44± 355.16)ms] and the shifting function [(380.34±153.18) ms] in the obese group were significantly longer than those in the normal weight group [(14.86±20.27, 888.38±286.57, 1 126.20± 287.43 , 323.12±134.71) ms] ( t =4.26, 4.06, 1.92,2.26, P < 0.05 ); inhibitory function (0.91±0.09) and 1-back (0.73±0.24) were also significantly less correct than in the normal weight group (0.94±0.05, 0.83±0.21) ( t =-2.04, -2.04, P <0.05). Obese adolescents showed moderate adverse effect sizes in the inhibition function ( d =0.746,0.712) and the refresh function 1-back, and smaller adverse effect sizes in the refresh function 2-back and the conversion function( d =0.497,0.398).
Conclusion
Obese adolescents have significant executive function deficits, but the degree of adverse varies across sub-functions, with inhibitory function being the core deficit component of executive function in obese adolescents.

Chinese Journal of School Health 2024;45(3):317-321
Objective:
To explore the relationship between cardiorespiratory fitness and executive function in Chinese adolescents, so as to provide a reference for promoting the overall development of Chinese adolescents physical and mental health.
Methods:
From September to December 2022, a total of 5 018 adolescents aged 13 to 18 years from Shanghai, Suzhou, Taiyuan, Wuyuan, Xingyi, and Urumqi were selected by stratified cluster sampling method to assess cardiorespiratory fitness and executive function. Pearson s correlation and linear hierarchical regression were performed to analyze the relationship between cardiorespiratory fitness and executive functions.
Results:
Among the sample of adolescents, maximal oxygen consumption (VO 2max ) was negatively correlated with the refreshing(1-back, 2-back) and conversion executive function responses ( r=-0.07, -0.12, -0.12, P <0.01). Linear regression analysis showed that VO 2max was negatively correlated with the reaction times of the refreshing(1-back, 2-back) and conversion functions ( B=-2.99, -6.44, -1.69, P <0.01).
Conclusions
Higher cardiorespiratory fitness among adolescents is associated with better performance in executive function. Teenagers should strengthen high intensity cardiopulmonary endurance exercise to promote the improvement of executive function.

Objective:
To explore the intervention effect of different intensity of classroom physical exercise on cardiorespiratory fitness and executive function of Tibetan first grade students at high altitude, so as to provide reference for improving the level of cardiorespiratory fitness and executive function of Tibetan adolescents.
Methods:
From September to December 2020, 184 Tibetan students from five first grade classes in a middle school in Lhasa, Tibet, were randomly assigned into a control group (81 students in two classes) and an intervention group (103 students in three classes). Both groups followed the same teaching programme, but the intervention group received 36 sessions of moderate to high intensity classroom physical activity, one session per day, Monday,Wednesday and Friday, for 12 weeks. Before and after the intervention, cardiorespiratory fitness and executive function were tested by 20m round trip running and Flanker s experimental paradigm, 2-back s experimental paradigm, and More odd shifting experimental paradigm for inhibitory control, refreshing memory, and switching flexibility, and the results were analysed by analysis of covariance (ANCOVA) to compare the results of the pre and post intervention periods.
Results:
The maximum oxygen uptake (VO 2max ) of Tibetan first grade students in the intervention group increased by 2.25 mL/(kg〖WW)〗·〖WW(〗min) compared with the control group after the intervention ( t =-3.89, P <0.01); the response time of the inhibitory function was reduced by 4.40 ms, that of the refreshing function by 196.06 ms, and that of the switching function by 92.72 ms in the intervention group compared with the control group ( t =2.98, 4.82 ,3.21, P <0.05).
Conclusion
The 12 week moderate to high intensity classroom physical activity intervention has different degrees of improvement effects on cardiorespiratory fitness and executive function in Tibetan adolescents.

Abstract
Executive function is an advanced cognitive process aimed at the flexible coordination, optimization, and control of the cognitive processes of task solving in order to accomplish a specific task, ensuring that the individual produces effective behaviors, including inhibitory control, working memory, and cognitive flexibility. Given the sensitivities and specificities that characterize an individual s physical and mental development during adolescence, this period is critical for the development of executive function in adolescents. In the paper, the influencing factors of adolescents executive function development are systematically described from three dimensions, namely, biology, environment and lifestyle; by analyzing the mechanisms and differences in the effects of different influencing factors, this editorial provides a scientific basis for adolescents executive function improvement and intervention.

Objective:
To explore the characteristics and related factors of adolescent executive function, so as to provide theoretical basis for promoting the development of adolescent executive function.
Methods:
A total of 5 018 adolescents aged 13-18 from Shanghai, Suzhou, Taiyuan, Wuyuan, Xingyi and Urumqi were selected by convenient cluster random sampling method from September to December 2022, and their basic information, family status, lifestyle behavior, physical fitness and executive function were investigated by questionnaire survey. Considering the heterogeneity between schools, a multilevel Logistic model was established to analyze the related factors of adolescent executive function.
Results:
The inhibitory function of high school students was better than that of middle school students (Z=-2.69). In terms of refreshment function, high school students were superior than middle school students (1-back:Z=-11.32; 2-back:Z=-11.36), and male students were superior than female students (2-back:Z=-2.18); in terms of shifting function, high school students were superior than middle school students (Z=-2.63), and boys were superior than girls (Z=-7.10)(P<0.05). The results of multilevel model analysis showed that the executive function of adolescents was clustered at the school level. At the individual level, junior high school refreshment function (1-back:β=56.94; 2-back:β=127.00), and shifting function (β=35.64) were worse than that of high school students; the refreshment function 2-back (β=-21.24) and shifting function (β=-28.42) of male students were better than those of female students; the refreshment function 2-back of nononly child was better than that of only child (β=-19.36); refreshment function of low fitness was worse than that of high fitness (β=37.35); the shifting function of the video screen time not up to standard was better than that of the standard (β=-14.30)(P<0.05).
Conclusions
The executive function of high school students is better than that of middle school students, the refreshment function and shifting function of boys are better than that of girls. Family environment, lifestyle and physical health are significant factors related to executive function of Chinese adolescents. By raising awareness of the major supporting and impeding factors for executive functioning in adolescents, it can help to develop effective intervention programs for adolescents.

The incidence of osteoporotic thoracolumbar vertebral fracture (OTLVF) in the elderly is gradually increasing. The kyphotic deformity caused by various factors has become an important characteristic of OTLVF and has received increasing attention. Its clinical manifestations include pain, delayed nerve damage, sagittal imbalance, etc. Currently, the definition and diagnosis of OTLVF with kyphotic deformity in the elderly are still unclear. Although there are many treatment options, they are controversial. Existing guidelines or consensuses pay little attention to this type of fracture with kyphotic deformity. To this end, the Lumbar Education Working Group of the Spine Branch of the Chinese Medicine Education Association and Editorial Committee of Chinese Journal of Trauma organized the experts in the relevant fields to jointly develop Clinical guidelines for the diagnosis and treatment of osteoporotic thoracolumbar vertebral fractures with kyphotic deformity in the elderly ( version 2024), based on evidence-based medical advancements and the principles of scientificity, practicality, and advanced nature, which provided 18 recommendations to standardize the clinical diagnosis and treatment.

Objective:To investigate the risk factors for retrograde type A dissection (RTAD) associated with thoracic endovascular aortic repair (TEVAR) which provided the basis for clinical risk stratification and treatment decision.Methods:The clinical data of 1 688 patients with thoracic aortic disease who underwent TEVAR in our center from January 2004 to December 2019 were retrospectively analyzed. The pathological classification included aortic dissection (1 592 cases) and other thoracic aortic diseases (96 cases). Univariate analysis and categorical multiple logistic regression analysis were used to explore the risk factors for the development of RTAD during or after TEVAR.Results:A total of 18 cases of RTAD were found, with an overall incidence of 1.1% (18/1 688), all of which occurred in aortic dissection group. After adjusting for confounding factors, multivariate logistic regression analysis showed that the incidence of RTAD was significantly decreased(OR=0.27,95%CI 0.07-0.96, P=0.043) when the oversize of stentgraft was 11%-20%, the oversize of stentgraft was ≤10% as the control group, and the difference was statistically significant( P<0.05). The ascending aorta diameter was <40 mm as the control group, and there was no significant difference in the incidence of RTAD between the ≥40 mm group and the control group(OR=2.71,95%CI 0.94-7.84, P=0.065). Conclusions:Aortic dissection is more likely to develop RTAD than other thoracic aortic diseases. A proper stentgraft oversizing ratio could reduce the probability of RTAD. That is to say that a too low stentgraft oversizing ratio is not recommended.

OBJECTIVE To investigate the clinical efficacy and safety of rituximab (RTX) followed by belimumab (BLM) in patients with severe systemic lupus erythematosus(SSLE). METHODS Nine SSLE patients, who were treated with RTX followed by BLM for more than 6 months in the Department of Rheumatology and Immunology of the First Affiliated Hospital of Zhengzhou University from October 2020 to June 2021, were enrolled. Baseline clinical data of patients, laboratory examination results and basic treatment status at weeks 0, 4, 12, and 24 of medication were collected retrospectively. The patients’ systemic lupus erythematosus disease activity index (SLEDAI) score, glucocorticoid dosage and serological indicators (complement C3, complement C4, serum albumin, and 24-hour urine protein quantification) level were analyzed. At the same time, the occurrence of adverse drug reaction was collected. RESULTS All 9 patients completed more than 24 weeks of RTX followed by BLM therapy. All patients suffered from renal impairment, of which 7 (77.8%) had renal pathology support, 3(33.3%) had blood system damage and 2 (22.2%) had nervous system damage. During treatment, with the prolongation of treatment time, the SLEDAI score, 24- hour urinary protein quantification, and glucocorticoid dosage of patients showed a significant downward trend, and ultimately decreased to the normal index level (P<0.05); serum albumin, complement C3 and complement C4 all showed a significant upward trend, eventually rose to the normal index level (P<0.05). During treatment and follow-up, 1 patient developed herpes zoster, 1 patient developed upper respiratory tract virus infection, and 1 patient developed urinary system bacterial infection. All patients recovered after symptomatic treatment. CONCLUSIONS In sequential use of RTX followed by BLM for SSLE, early administration of RTX can quickly stabilizethe condition, significantly alleviate clinical symptoms, and gradually normalize specific serological indicators; subsequent administration of BLM can reduce the type and dosage of basic treatment drugs; there is no increase in the incidence of adverse drug reactions.
