Objective: To evaluate the intervention efficacy of integrated group social skills training on social ability in school age patients with high functioning ASD, so as to provide a reference for improving social skills in children with high functioning ASD. Methods: From January 2021 to December 2023, 62 children aged 7-12 with high functioning ASD who visited the Children s Psychiatry Outpatient Department of the Affiliated Kangning Hospital of Ningbo University were recruited, and were randomly divided into a training ( n =31) and a control group ( n =31) by a random number table method. The training group received a 20 week structured group social training program (mental interpretation courses and social courses), while the control group received only conventional treatment. Chinese version of Griffith Empathy Measure Parent Ratings (GEM-PR) and Social Response Scale (SRS) were used to assess the symptoms of social deficits before and after treatment. Emotional face recognition tasks and eye movement trajectories were used to test the characteristics of social visual attention in children with ASD. Group comparison was conducted using t-test and Mann-Whitney U test. Results: At baseline, there were no significant differences in GEM-PR score ( t = -1.20 to -0.81), SRS score ( t =-0.36-1.75), emotional face recognition accuracy and reaction time ( t =-0.58-1.85), and eye movement trajectory ( U/t =-1.63-0.29) between the two group ( P >0.05). After intervention, the total GEM-PR score and empathic cognitive factor score of training group [18.00(10.00，24.00)，9.00(8.00，13.00)] were significantly higher than those of the control group [12.00(-1.00，18.00)，2.00(-2.00，7.00)], and the total SRS score and social cognition, social perception, social communication, social motivation (73.23±14.20, 16.16±2.72, 6.58±2.50, 24.29±5.61, 9.52±3.73) were significantly lower than those of the control group (95.26±15.29, 19.90±2.84, 12.58±2.49,31.94±6.38, 13.74±4.81) ( U/t =-2.38, -4.59; -5.88, -5.29, -9.47, -5.01, -3.87, P <0.05). The overall correct rate of emotional face recognition and the correct rate of angry, fearful and neutral faces recognition in the training group [(81.55±6.62)%，(76.86±12.06)%，(79.61±12.42)%，(94.27±6.26)%] were significantly higher than the control group [(70.55±13.82)%，(62.82±18.77)%，(67.18±18.85)%，(79.60±20.05)%], and the average reaction time [(2 226.70±274.43)ms] was lower than the control group [(2 417.27±324.10)ms] (t=4.00, 3.50, 3.07, 3.89, -2.42, P<0.05). The time to first eye gaze [764.74 (748.64, 793.73) ms] in the training group was significantly lower than that in the control group [810.92 (782.86, 877.42) ms], and the proportion of moderatetohigh intensity attention area in the face [(37.37±1.27)%] was significantly higher than that in the control group [(30.34±1.23)%] (U/t=3.44, 8.89, P<0.05). Conclusion Integrated group social training can significantly improve the social communication and empathy ability of high functioning ASD children, increase active attention and recognition ability of faces, and improve mental development of children with ASD.

ObjectiveTo establish an adjusted Serfling regression model to estimate the excess cases and the excess epidemic period of hand-foot-mouth disease (HFMD) in Beijing from 2011 to 2019, so as to provide data support and decision-making basis for HFMD prevention and control. MethodsThe weekly number of HFMD cases in Beijing from 2011 to 2019 was utilized for adjusted the Serfling regression model. Then the adjusted model was used to fit the baseline and epidemic threshold of HFMD in Beijing from 2011 to 2019, calculating the excess cases and determining the excess epidemic period. ResultsA total of 279 306 cases of HFMD were reported in Beijing from 2011 to 2019, with the climax of the disease occurring in summer and autumn. After adjusting the fitting R² of the Serfling regression model to 0.773, a total of 10 excess epidemic periods totaling 92 weeks were estimated, mainly occurring in summer. The highest number of excess cases during an excess epidemic period was found in 2014 (1 272 cases, 95%CI: 990‒1 554), accounting for 65.04% of the actual cases (95%CI: 50.62%‒79.46%). ConclusionThe adjusted Serfling regression model fits well and can be utilized for early warning of HFMD and estimating the disease burden caused by HFMD.

ObjectiveTo identify the characteristic exhaled volatile organic compounds （VOCs） associated with postoperative pulmonary complications （PPCs） in patients after abdominal surgery. MethodsThis study prospectively enrolled 76 patients with tracheal intubation who were transferred to intensive care unit （ICU） after abdominal surgery at Peking University People's Hospital between December 10， 2022 and June 30， 2023. The patients' basic information was collected during their perioperative period， and their exhaled VOCs were collected within 24 hours after their admission to the ICU， and then analyzed by gas chromatography and mass spectrometry （GC-MS）. According to whether PPCs occurred 24 hours after surgery， the patients were divided into PPCs group （n=44） and non-PPCs group （n=32）， and the differences of VOCs were compared between the two groups. Lasso regression analysis was used to screen the valuable variables of VOCs， and Logistics regression analysis to determine the characteristic VOCs associated with the occurrence of PPCs. ResultsAmong the 76 patients， 44 had PPCs and 32 had no PPCs. Lasso regression analysis screened 4 PPCs-related compounds from exhaled VOCs of two groups for further analysis and Logistics regression analysis showed that the increase of 1-Hexadecanol content in exhaled breath was significantly correlated with the occurrence of PPCs （OR： 1.000， P=0.002）. ConclusionThis study indicated that the increased content of 1-Hexadecanol in patients' exhaled breath after abdominal surgery may be associated with the occurrence of PPCs.

BackgroundAs a high prevalence disorder， schizophrenia has caused significant burden to family and society due to the impairment of occupational and social function. Currently， the dominant vocational training model in China follows a paternalistic， clinician-led decision-making approach. Although it improves patients' social function to some extent， it undermines their autonomy and treatment adherence. Therefore， it is urgently necessary to explore a new intervention method to enhance treatment compliance and social function in patients. ObjectiveTo explore the impact of shared decision-making oriented vocational training on social function in hospitalized schizophrenia patients， so as to provide references for rehabilitation interventions. MethodsA total of 68 patients diagnosed with schizophrenia according to the International Classification of Diseases， tenth edition （ICD-10） criteria were consecutively enrolled from January to June 2024 at The Third People's Hospital of Wenjiang Distric， Chengdu. Participants were randomly allocated into the research group （n=34） and the control group （n=34） using a random number table method. Both groups received routine rehabilitation training， while the research group received shared decision-making oriented vocational training for 12 weeks， 2 times a week for 2 hours each time. Before and at the 4^th and 12^th week of intervention， two groups were evaluated by General Self-Efficacy Scale （GSES）， Stigma Scale for Mental Illness （SSMI）， Scale of Social function of Psychosis Inpatients （SSFPI） and Inpatient Psychiatric Rehabilitation Outcome Scale （IPROS）. ResultsA total of 63 participants completed the study， with 30 cases in the research group and 33 cases in the control group. Repeated measures ANOVA revealed statistically significant time effects and interaction effects in both groups for GSES， SSMI， SSFPI and IPROS scores （F=20.451， 16.022； 26.193， 12.944； 23.957， 5.023； 11.776， 3.985， P<0.05 or 0.01）， while no significant group effects were observed （F=0.188， 0.742， 1.878， 0.474， P>0.05）. At the 12^th week of intervention， there were statistically significant differences in GSES， SSMI， SSFPI and IPROS scores between the two groups. ConclusionShared decision-making oriented vocational training may help to improve social function in patients with schizophrenia. ［Funded by 2023 Chengdu Medical Research Project （number， 2023468）］

Objective: To understand classroom environmental conditions and their association with spinal curvature abnormalities among students of primary and secondary schools in Guizhou Province, so as to provide a basis for formulating school health policies and scientific prevention and control measures for abnormal spinal curvature in students. Methods: Using a stratified random sampling method, 471 schools (2 811 classrooms) were selected annually across the province from 2022 to 2024 in order to monitor and evaluate classroom environment according to national standards. Spinal examinations were conducted for 196 606 (2022), 194 876 (2023), and 195 048 (2024) students, and χ 2 test was used to analyze the correlation of desk and chair compliance with student spinal curvature abnormalities. Results: The qualified rates of classroom blackboard illuminance uniformity ( 85.41 %) and the blackboard size (82.24%) were the highest in primary and secondary schools in Guizhou Province, while the average blackboard surface illumination qualified rate (20.10%) was the lowest. The average desk illumination (50.11%-58.63%), desk illumination uniformity (61.92%-72.27%) and qualified noise rate (50.04%-51.94%) increased significantly in 3 years; in addition, the compliance rate of desks and chairs decreased from 25.00% to 13.52%, and the differences were all statistically significant ( χ 2=42.48, 80.93, 46.09, 129.72, all P <0.05). Middle school classrooms outperformed primary schools in terms of per capita area, average blackboard illuminance, blackboard illuminance uniformity, average desktop illuminance, desktop illuminance uniformity, and noise compliance ( χ 2=311.55, 12.41, 20.64, 40.76, 10.25, 52.47), but had lower compliance for blackboard size and reflectance ( χ 2=537.29, 7.59) (all P <0.01). Urban schools had higher compliance than suburban schools for per capita area, average blackboard illuminance, average desktop illuminance, and desktop illuminance uniformity ( χ 2=73.71, 17.68, 29.30 , 36.03), but lower compliance for desk-chair suitability, blackboard size, and blackboard reflectance ( χ 2=4.72, 26.02, 5.43 ) (all P <0.05). The spinal curvature abnormality detection rate was 0.83%. A significant association was found between abnormality detection and desk-chair non compliance ( χ 2=223.85, P <0.01). Conclusions Classroom environment hygiene in Guizhou schools is suboptimal. Strengthening school environmental hygiene infrastructure and greater attention to its impact on student s health are essential.

Objective: To understand the epidemiological characteristics of abnormalities spinal curvature among children and adolescents in Karst landform in Guizhou Province, so as to provide a scientific basis for targeted comprehensive intervention. Methods: From September to December 2023, 194 875 children and adolescents aged 6-18 were selected from all countieldistricts of 9 cities (prefectures) in Guizhou Province by stratified random cluster sampling method according to the proportion of Karst landform area in Guizhou Province for carrying out spinal curvature abnormality screening, and a questionnaire survey was conducted on 139 449 students in the fourth grade and above of primary school. Binary Logistic regression was used for multivariate analysis. Results: The detection rate of abnormal spinal curvature among children and adolescents aged 6-18 in Guizhou Province was 1.13%. The detection rates of abnormal spinal curvature in areas with a high proportion of Karst landform, areas with a low proportion of Karst landform, intercalation areas, and nonKarst landform areas were 1.10%, 2.00%, 0.90%, and 0.60%, respectively. Among them, the detection rates of abnormal spinal curvature in female students (2.40%, 1.60%, 0.90%) in areas with a low proportion of Karst landform, intercalation areas and nonKarst landform were higher than those in male students (1.60%, 0.10%, 0.30) (χ2=12.66, 112.69, 30.22, all P<0.05). The detection rates of abnormal spinal curvature among senior high school students (2.00%, 4.30%, 1.40%, 1.30%) in different Karst landform distributions were successively higher than those among junior high school students (1.40%, 3.20%, 1.00%, 0.60%) and primary school students (0.70%, 0.80%, 0.60%, 0.30%) (χ2=306.11, 175.80, 14.24, 39.57, all P<0.05). The results of multivariate Logistic regression analysis showed that the detection rates of abnormal spinal curvature in both highproportion and lowproportion Karst landform areas were higher than those in nonKarst landform areas [OR(95%CI)=1.84(1.05-2.25), 1.60(1.23-2.09), both P<0.05]. Conclusion The detection rate of abnormal spinal curvature in children and adolescents aged 6-18 in Guizhou Province is related to the distribution of Karst landform, so it is necessary to strengthen screening and appropriate comprehensive interventions.

OBJECTIVE To assess the cost-effectiveness of durvalumab combined with chemotherapy as a first-line treatment for advanced biliary tract cancer from the perspective of the Chinese healthcare system. METHODS Using data from the TOPAZ-1 clinical trial， a three-state Markov model comprising progression-free survival （PFS）， progressive disease （PD） and death was developed， with a cycle length of 21 days and a 10-year time horizon. Patients in the observation group received durvalumab in combination with gemcitabine and cisplatin， whereas those in the control group received placebo plus the same chemotherapy regimen. The evaluation indexes were quality-adjusted life year （QALY） and the incremental cost-effectiveness ratio （ICER）. The willingness-to-pay （WTP） threshold was set at three times the 2024 Chinese per capita gross domestic product （GDP） （287 247 yuan/QALY）. The sensitivity analyses， along with scenario analyses， were performed. RESULTS In the base-case analysis， the ICER of observation group compared to control group was 1 166 344.46 yuan/QALY， far exceeding the WTP threshold， indicating that the regimen was not cost-effective. One-way sensitivity analysis identified the PD state utility， discount rate， cost of durvalumab， and PFS state utility as the main drivers of ICER variation. Probabilistic sensitivity analysis showed that， at the above WTP threshold， the probability of the acceeptance of this regimen was 0， further supporting the robustness of the base-case findings. In the scenario analysis， inclusion of a patient assistance program reduced the ICER to 235 885.16 yuan/ QALY， below the above WTP threshold， suggesting cost-effectiveness under this assistance program. However， when applying a regional WTP threshold set at three times the per capita GDP （158 475 yuan/QALY） of Gansu Province （the province with the lowest GDP in China in 2024）， the ICER remained above the threshold， indicating that the regimen was not cost-effective at the regional level. CONCLUSIONS At current pricing， durvalumab plus chemotherapy as a first-line treatment for advanced biliary tract cancer is not cost-effective in China. Although the introduction of a patient assistance program can substantially reduce the ICER and achieve cost-effectiveness at a WTP threshold set at three times the 2024 per capita GDP of China， due to limited affordability in low-income areas， the program remains not cost-effective.

AIM: To explore the efficacy of bilateral lateral rectus recession in the treatment of basic intermittent exotropia. METHODS: A prospective study was conducted on 104 patients with basic intermittent strabismus admitted to our hospital from October 2022 to October 2023, patients were randomly divided into a study group of 52 cases and a control group of 52 cases using a random number ranking method. The control group received unilateral recess-resect, while the study group received bilateral lateral rectus recession, the differences in surgical success rate, postoperative strabismus, and postoperative exotropia drift were compared between two groups.RESULTS: There was no statistically significant difference between the two groups at 1 d, 1, 3, and 6 mo after surgery(all P>0.05). The strabismus in the 6 m and 33 cm eye positions at 1, 3, and 6 mo after surgery were lower than those at 1 d after surgery(all P<0.05). However, there was no statistically significant difference in the strabismus in the 6 m and 33 cm eye positions between the two groups at 1 d, 1, 3, and 6 mo after surgery(all P>0.05), and there was statistical significant difference between the two groups in exotropia drift at different postoperative time points(all P<0.05). The exotropia drift of both groups increased at 3 and 6 mo after surgery compared to 1 mo after surgery, and the exotropia drift at 6 mo after surgery was greater than that at 3 mo after surgery(all P<0.05). However, the exotropia drift of the study group at 3 and 6 mo after surgery was lower than that of the control group(all P<0.001). CONCLUSION: Bilateral lateral rectus recession for the treatment of basic-type intermittent exotropia effectively reduces the amount of postoperative exotropia drift, and it has better long-term stability.

Objective: To compare the effects of high intensity interval training (HIIT) exercise prescription based on machine vision and routine on HIIT the physical and mental health of female college students with simple obesity, so as to provide a basis for the development of weight loss intervention plans for this population. Methods: From August 2023 to February 2024, 115 female college students with simple obesity, selected from Lianyungang Vocational and Technical College and East China Normal University, were randomly divided into a control group ( n =57) and an observation group ( n =58) according to a random number table. The control group received routine HIIT, while the observation group received machine vision based on HIIT exercise prescription (including image acquisition module, image processing module, database management module, backend computer processing and feedback, intelligent evaluation module, which could be customized according to the subjects preferences, providing exercise prescription based on the selected training program and supervised its standardized completion of the training plan). Both were intervened for 12 weeks, 30 minutes each time, once every 2 days, and rest every Sunday. The t-test was used to compare body shape, glucose and lipid metabolism, cardiopulmonary function indicators, anxiety and depression states between two groups before and after intervention. Results: Before intervention, there were no statistically significant differences in physical and mental health status indicators between two groups of female college students ( t =0.13-0.86, all P >0.05). After intervention, body mass indexes, waist hip ratios, body fat percentage, fasting plasma glucose, 2hour postprandial plasma glucose, hemoglobin A1c, triglycerides, total cholesterol, lowdensity lipoprotein cholesterol (LDL-C), anxiety and depression scores were all reduced in both groups ( t-observation =-6.94 to -12.92, t-control =-2.71 to -10.95 ), of which the observation group [(23.46±2.18)kg/m 2, 0.70±0.06, (28.03±3.16)%, (4.55±0.67)mmol/L, (6.03±0.74)mmol/L, (5.10±0.70)%, (1.63±0.31)mmol/L, (4.24±0.58)mmol/L, (2.45±0.43)mmol/L, 35.28±4.76, and 33.03±4.03] were lower compared with the control group [(26.54±2.32)kg/m 2, 0.77±0.06, (30.74±4.38)%, (5.03±0.76)mmol/L, (6.62±0.82)mmol/L, (5.82±0.73)%, (1.98±0.35)mmol/L, (4.95±0.61)mmol/L, (2.88±0.47)mmol/L, 39.18±5.04, and 37.25±4.16] ( t =-7.34, -6.26 , -3.81, -3.59, -4.05, -5.40, -5.68, -6.40, -5.12, -4.27, -5.53)(all P <0.05). After intervention, high density lipoprotein cholesterol, stroke volume, left ventricular ejection fraction, maximum oxygen consumption, volume of tidal, and vital capacity increased in both groups ( t-observation =7.43-18.23, t-control =3.89-10.13), of which the observation group [(1.49±0.22)mmol/L, ( 72.35± 4.69)mL, (68.95±5.10)%, (36.97±3.22)mL/(kg ·( min), (25.29±4.11)mL/(kg · ( min), and (3 374.26±169.54)mL] were higher compared with the control group [(1.23±0.20)mmol/L, (67.32±4.06)mL, (64.83±5.05)%, (33.24±3.14)mL/(kg · ( min), (23.01± 3.58 )mL/(kg · ( min), and (3 197.50±125.81)mL] ( t =6.63, 6.15, 4.35, 6.29, 3.17, 6.34)(all P <0.05). Conclusion HIIT exercise prescription based on machine vision has better effects than routine HIIT on impoving the body shape, glucose and lipid metabolism, cardiopulmonary function of female college students with simple obesity, and also their mental health.
