Objective To investigate the sleep status in children with autism spectrum disorder (ASD) and its relationship with executive function and neurodevelopment. Methods The medical records of 346 children with ASD in the hospital from April 2023 to January 2025 were retrospectively collected. The sleep status of children was investigated by Children’ s Sleep Habits Questionnaire (CSHQ). According to the score, the children were divided into good sleep group (CSHQ score<41 points, 189 cases) and sleep disorder group (CSHQ score≥41 points, 157 cases). The general data were compared between groups of children. Chinese version of Behavior Rating Inventory of Executive Function-Preschool Version (BRIEF-P) and developmental behavior assessment scale of children aged 0-6 years (Children's psychological scale-II) were used to analyze the relationship between sleep status and executive function and neurodevelopment in children with ASD. Results The CSHQ score of 346 children was (39.08±3.24) points, including 157 cases with CSHQ score≥41 points and 189 cases with CSHQ score<41 points. The proportion of severe previous medical history and executive function score in sleep disorder group were significantly higher than those in good sleep group, and the evaluation result of developmental quotient was lower than that in good sleep group (P<0.05). Logistic regression analysis showed that executive ability and neurodevelopment were closely related to sleep status in children with ASD (P<0.05). Spearman correlation analysis showed that sleep status in children with ASD was negatively correlated with executive function (r=-0.456, P<0.05), and was positively correlated with the developmental quotient (r=0.547, P<0.05). Conclusion The incidence rate of sleep disorder is high in children with ASD, and sleep status is closely related to executive function and neurodevelopment. Clinically, it is necessary to pay attention to the sleep problems in children with ASD, and take effective intervention measures to improve the sleep quality of children and promote the training of executive function and neurodevelopment.

Objective To investigate the changes in eosinophil counts and the activation of microglial cells in the brain tissues of mice at different stages of Angiostrongylus cantonensis infection, and to examine the role of microglia in regulating the progression of angiostrongyliasis and unravel the possible molecular mechanisms. Methods Fifty BALB/c mice were randomly divided into the control group and the 7-d, 14-d, 21-day and 25-d infection groups, of 10 mice in each group. All mice in infection groups were infected with 30 stage III A. cantonensis larvae by gavage, and animals in the control group was given an equal amount of physiological saline. Five mice were collected from each of infection groups on days 7, 14, 21 d and 25 d post-infection, and 5 mice were collected from the control group on the day of oral gavage. The general and focal functional impairment was scored using the Clark scoring method to assess the degree of mouse neurological impairment. Five mice from each of infection groups were sacrificed on days 7, 14, 21 d and 25 d post-infection, and 5 mice from the control group were sacrificed on the day of oral gavage. Mouse brain tissues were sampled, and the pathological changes of brain tissues were dynamically observed using hematoxylin and eosin (HE) staining. Immunofluorescence staining with eosinophilic cationic protein (ECP) and ionized calcium binding adaptor molecule 1 (Iba1) was used to assess the degree of eosinophil infiltration and the counts of microglial cells in mouse brain tissues in each group, and the morphological parameters of microglial cells (skeleton analysis and fractal analysis) were quantified by using Image J software to determine the morphological changes of microglial cells. In addition, the expression of M1 microglia markers Fcγ receptor III (Fcgr3), Fcγ receptor IIb (Fcgr2b) and CD86 antigen (Cd86), M2 microglia markers Arginase 1 (Arg1), macrophage mannose receptor C-type 1 (Mrc1), chitinase-like 3 (Chil3), and phagocytosis genes myeloid cell triggering receptor expressed on myeloid cells 2 (Trem2), CD68 antigen (Cd68), and apolipoprotein E (Apoe) was quantified using real-time quantitative reverse transcription PCR (RT-qPCR) assay in the mouse cerebral cortex of mice post-infection. Results A large number of A. cantonensis larvae were seen on the mouse meninges surface post-infection, and many neuronal nuclei were crumpled and deeply stained, with a large number of bleeding points in the meninges. The median Clark scores of mouse general functional impairment were 0 (interquartile range, 0), 0 (interquartile range, 0.5), 6 (interquartile range, 1.0), 14 (interquartile range, 8.5) points and 20 (interquartile range, 9.0) points in the control group and the 7-d, 14-d, 21-d and 25-d groups, respectively (H = 22.45, P < 0.01), and the median Clark scores of mouse focal functional impairment were 0 (interquartile range, 0), 2 (interquartile range, 2.5), 7 (interquartile range, 3.0), 18 (interquartile range, 5.0) points and 25 (interquartile range, 6.5) points in the control group and the 7-d, 14-d, 21-d and 25-d groups, respectively (H = 22.72, P < 0.01). The mean scores of mice general and focal functional impairment were all higher in the infection groups than in the control group (all P values < 0.05). Immunofluorescence staining showed a significant difference in the eosinophil counts in mouse brain tissues among the five groups (F = 40.05, P < 0.000 1), and the eosinophil counts were significantly higher in mouse brain tissues in the 14-d (3.08 ± 0.78) and 21-d infection groups (5.97 ± 1.37) than in the control group (1.00 ± 0.28) (both P values < 0.05). Semi-quantitative analysis of microglia immunofluorescence showed a significant difference in the counts of microglial cells among the five groups (F = 17.66, P < 0.000 1), and higher Iba1 levels were detected in mouse brain tissues in 14-d (5.75 ± 1.28), 21-d (6.23 ± 1.89) and 25-d infection groups (3.70 ± 1.30) than in the control group (1.00 ± 0.30) (all P values < 0.05). Skeleton and fractal analyses showed that the branch length [(162.04 ± 34.10) μm vs. (395.37 ± 64.11) μm; t = 5.566, P < 0.05] and fractal dimension of microglial cells (1.30 ± 0.01 vs. 1.41 ± 0.03; t = 5.266, P < 0.05) were reduced in mouse brain tissues in the 21-d infection group relative to the control group. In addition, there were significant differences among the 5 groups in terms of M1 and M2 microglia markers Fcgr3 (F = 48.34, P < 0.05), Fcgr2b (F = 55.46, P < 0.05), Cd86 (F = 24.44, P < 0.05), Arg1 (F = 31.18, P < 0.05), Mrc1 (F = 15.42, P < 0.05) and Chil3 (F = 24.41, P < 0.05), as well as phagocytosis markers Trem2 (F = 21.19, P < 0.05), Cd68 (F = 43.95, P < 0.05) and Apoe (F = 7.12, P < 0.05) in mice brain tissues. Conclusions A. cantonensis infections may induce severe pathological injuries in mouse brain tissues that are characterized by massive eosinophil infiltration and persistent activation of microglia cells, thereby resulting in progressive deterioration of neurological functions.

This study investigates the clinical differentiation and treatment strategies for bipolar disorder （BD） by analyzing the relationship of its core pathomechanisms including qi stagnation， blood stasis， phlegm turbidity， and heat constraint with bile acid metabolism. The imbalance of "yin in form and yang in function" leads to qi stagnation， blood stasis， phlegm turbidity， and heat constraint， which are critical in the pathogenesis and progression of BD. Bile acids regulate neuroinflammation， neural plasticity， and intestinal flora homeostasis through receptor-mediated pathways. It is believed that the physiological functions of bile acids concretely embody the concept of the "liver is yin in form and yang in function" theory. Clinically， prescriptions such as Sini Powder （四逆散） with the function of venting pathogen and resolving constraint， Wendan Decoction （温胆汤） of drying dampness and resolving phlegm， Longdan Xiegan Decoction （龙胆泻肝汤） of clearing liver and draining fire， and Huanglian Ejiao Decoction （黄连阿胶汤） of nourishing yin and blood can be used to nourish liver yin and restore liver yang function. These strategies may improve BD prognosis by modulating bile acid synthesis and metabolism.

Objective To compare the application values of the Ranson score,Bedside Index for Severity in Acute Pancreatitis(BISAP),CT Severity Index(CTSI)and Oxford Acute Severity of Illness Score(OA-SIS)in forecasting the new onset organ failure in the patients with severe acute pancreatitis(SAP).Methods The study was a retrospective analysis.A total of 126 cases of SAP receiving by the intensive care unit(ICU)and emergency ICU(EICU)of the Second Affiliated Hospital of Chongqing Medical University from January 2015 to June 2023 served as the study subjects.The clinical data of the patients were collected.The first time OASIS score,Ranson score,BISAP score and CTSI score were calculated within 48 h after the patients ente-ring ICU.The new onset organ failure served as the clinical outcome.The random forest and least absolute shrinkage and selection operator(LASSO)regression were used to screen the risk factors for new onset organ failure.The multivariate logistic regression was adopted to analyze the correlation between the four scoring systems and new onset organ failure in the SAP patients.The receiver operating characteristic(ROC)curve and the area under the curve(AUC)were adopted to analyze the predictive efficiency of 4 kinds of scoring sys-tems.Results The age in the organ failure group was higher than that in the non-organ failure group(P=0.039).The OASIS,Ranson,BISAP and CTSI scores in the organ failure group all were higher than those in the non-organ failure group(P＜0.05).The random forest and LASSO regression analysis results showed that Lac,Cr and myoglobin were the most important variables affecting the new onset organ failure in SAP pa-tients.The OASIS score(OR=1.27,95％CI:1.06-1.51,P=0.009)and Ranson score(OR=1.88,95％CI:1.03-3.43,P=0.040)were the independent influencing factors for predicting the new onset organ fail-ure in SAP patients.The ROC curve results showed that the area under the curve(AUC)of the OASIS score was the highest(AUC=0.830,95％CI:0.743-0.916).Conclusion The OASIS score is an independent risk factor for predicting the new onset organ failure in SAP patients,moreover has the highest predictive efficiency in predicting the new onset organ failure.

Objective To explore the role of Schlafen4(SLFN4)in acute pneumonia induced by hypervirulent Klebsiella pneumoniae(hvKp)via intratracheal aerosolization.Methods Differential expression gene Slfn4 was identified after infection with hvKp based on RNA sequencing(RNA-seq)and single-cell RNA sequencing(scRNA-seq)data before Slfn4-/-mice were obtained via CRISPR/Cas gene editing technology.Slfn4-/-mice and wild mice were challenged via intratracheal aerosolization.Mortality and weight changes were recorded for 14 d,while pathological changes and expression levels of interleukin-6(IL-6),IL-17A,IL-1β,and tumor necrosis factor-α(TNF-α)were detected at 48 h post-infection.Results SLFN4 expression was significantly increased in wild mice after infection with hvKp.Survival was significantly increased,and weight loss was mitigated before gradual recovery in Slfn4-/-mice after infection.The knockout of SLFN4 attenuated alveolar wall thickening,diminished neutrophil infiltration,and suppressed pro-inflammatory cytokine production(IL-6,IL-17A,IL-1β,TNF-α)in the lung at 48 h post-infection.Conclusion The deletion of SLFN4 may suppress the expression of specific pro-inflammatory cytokines and attenuate neutrophil over-recruitment in the lung,thereby alleviating pneumonia in mice after hvKp infection.

Objective: To investigate the prospective effects of intake of each food group on the development of lung function of pupils,so as to provide theoretical basis for promoting the healthy development of lung function and preventing chronic respiratory diseases in Chinese children. Methods: A cluster stratified sampling method was used to select a total of 893 pupils in grades 2-5 from Chengdu in November 2021. Dietary data of respondents were collected using a food frequency questionnaire within the past year,then the food group intake was categorized into T1, T2 and T3 from low to high by the trichotomous method, and anthropometric measurements including lung capacity were obtained in 2022. Logistic regression models and test for trend were used to analyze the prospective effects of intake of each food group on lung function development of pupils. Results: Among male students, consumption of vegetables [118.6(50.5, 188.2)g/d] and milk and dairy products [200.0(73.3, 250.0)g/d] were higher in the excellent lung capacity group than in the non excellent lung capacity group [90.0(37.1, 192.9), and 178.6(35.7, 250.0)g/d],with statistically significant differences ( Z =-1.98, -2.24); among girls, the group with excellent lung capacity consumed less staple food [391.1(273.6, 511.4)g/d] than the group with non excellent lung capacity [407.4(309.5, 594.3)g/d], and the group with excellent lung capacity consumed more aquatic products [31.2(14.6, 69.8)g/d] and milk and dairy products [215.0(107.1, 250.1) g/d ] than that of the non excellent lung capacity [19.4(10.7, 58.3), 114.3(35.7, 250.0)g/d] ( Z =-2.01, -3.33, -5.10)( P < 0.05 ). After adjusting for energy, body mass index Z score(BMI Z ), mother s education level, averge family income monthly, whether presence of smokers in the living environment, and whether participation in physical activities during the past week, among male students, T3 group of vegetable intake ( OR =0.48, 95% CI = 0.27-0.86), T2 group of bean and soy product intake ( OR = 0.52 , 95% CI =0.27-0.96)，T2 and T3 groups of milk and dairy products intake (T2： OR =0.54, 95% CI =0.31-0.93; T3： OR = 0.52 , 95% CI =0.30-0.90) were negatively associated with non excellent lung capacity ( P <0.05). Among girls, T3 group of aquatic product intake( OR =0.52, 95% CI =0.28-0.97), T2 and T3 groups of milk and dairy product (T2: OR =0.44, 95% CI =0.25- 0.76 ;T3: OR =0.33, 95% CI =0.19-0.59) were negatively associated with nonexcellent lung capacity, whereas the T2 group of red meat intake ( OR =2.51, 95% CI =1.37-4.67) was positively associated with non excellent lung capacity. Non excellent lung capacity was found to be negatively associated with vegetable and milk and dairy product intake in boys by test for trend; in girls, milk and dairy products intake was negatively associated with non excellent lung capacity, whereas red meat intake was positively associated with non excellent lung capacity ( t =-1.13，-0.44；-3.03，1.95, P trend <0.05). Conclusions Milk and dariy products intakes reduce the risk of non excellent lung capacity in pupils, vegetables intakes reduce the risk of non excellent lung capacity in boys, and the intake of red meat increases the risk of non excellent lung capacity in girls. Promoting rational food choices is necessary for children to improve healthy lung development.

Objective: To explore the differences in the gut microbiota of primary school students with different levels of sugar sweetened beverage intake, so as to provide scientific evidence for better identification of health risks in children and the development of targeted health policies. Methods: In June 2022, a total of 192 healthy primary school students from Chengdu were selected using a stratified cluster random sampling method. The sugar sweetened beverage intake was assessed through a dietary frequency questionnaire. Based on the median daily sugar sweetened beverage intake, primary school students were categorized into a low intake group ( n =96) and a high intake group ( n =96). The gut microbiota in fresh fecal samples from the two groups of primary school students was analyzed using 16S rRNA high throughput sequencing, and the diversity and community structure differences in the gut microbiota were compared. Results: Children in the low intake group had a sugar sweetened beverage intake of (21.3±1.6) mL/d, while the high intake group had an intake of (269.6±37.3) mL/d. Diversity analysis results showed that there were no statistically significant differences between the low intake and the high intake group in terms of α diversity metrics: Observed_otus index [298.50 (259.75, 342.25), 305.50 (244.25, 367.75)], Goods_coverage index [1.00 (1.00, 1.00), 1.00 (1.00, 1.00)], Chao index [304.18 (260.75, 348.78), 305.88 (245.68, 370.88)], Shannon index [5.88 (5.29, 6.45), 5.71 (4.89, 6.28)] and Simpson index [0.95 (0.91, 0.97), 0.94 (0.88, 0.97)] ( Z =-0.64, -0.76, -0.54, -1.76, -1.67, P >0.05). Furthermore, no statistically significant difference was observed in β diversity between the two groups ( R 2=0.006, P >0.05). At the genus level, the abundance of Blautia [0.033 (0.018, 0.055)] and Fusicatenibacter [0.009 (0.005, 0.015)] were higher in the low intake group compared to the high intake group [0.024 (0.013, 0.041),0.006 (0.003, 0.011)]and differences were statistically significant ( Z =-2.52, -2.81, P <0.05). LEfSe analysis highlighted intergroup differences primarily in Blautia, Fusicatenibacter and Sarcina( LDA= 3.56,3.12,3.53, P <0.05). Conclusions There is no significant difference in the diversity and overall structure of the gut microbiota in primary school students with different levels of sugar sweetened beverage intake. However, there are species variations at the genus level. The information can serve as a scientific basis for identifying health risks in primary school students and formulating targeted health strategies.

Objective To investigate the diagnostic value Tamm-Horsfall protein(THP)and osteopontin(OPN)in serum and 24-hour urine for urolithiasis.Methods A total of 101 patients with urolithiasis who underwent flexible ureteroscopy lithotripsy at the Urology Department of Civil Aviation General Hospital from April 2020 to March 2023 were included as the stone group,and 50 healthy individuals were enrolled as the control group.The samples of serum and 24-hour urine samples were collected from both the groups,and the levels of THP and OPN were measured using enzyme-linked immunosorbent assay(ELISA).Logistic regression analysis was performed to evaluate the association between each biomarker and urolithiasis,and receiver operating characteristic(ROC)curves were plotted to assess their diagnostic value.Results The stone group showed significantly lower THP levels(20.13[13.12,26.03]mg/d)and OPN levels(51.24[36.72,101.37]μg/d)in 24-hour urine,and THP levels(182.01[160.91,209.20]ng/mL)and OPN lev-els(18.76[15.72,22.48]ng/mL)in serum compared to the control group(all the P＜0.001).Binary Logistic regression analysis re-vealed that THP(OR=0.736,95％CI:0.606-0.895),OPN(OR=0.975,95％CI:0.958-0.993)and citrate(OR=0.067,95％CI:0.012-0.376)in 24-hour urine,and THP(OR=0.946,95％CI:0.908-0.986)and OPN(OR=0.896,95％CI:0.803-0.999)in ser-um were the protective factors for urolithiasis,while calcium level(OR=2.125,95％CI:1.243-3.633)24-hour urine was a risk factor(all the P＜0.05).ROC curve analysis showed that the areas under the curve(AUCROC)for the individual diagnosis of urolithiasis were 0.846,0.809,0.786,0.823,0.748,and 0.755 for the above six biomarkers,respectively.The AUCROC for the combined diagnosis u-sing THP+OPN in serum,THP+OPN in 24-hour urine and all the six biomarkers were 0.882,0.920 and 0.984,respectively,indica-ting better diagnostic performance.Conclusion The combined detection of the THP and OPN levels in serum and 24-hour urine may have good diagnostic value for urolithiasis and serve as potential diagnostic biomarkers.
