ObjectiveTo explore the effect of Polygonati Odorati Rhizoma polysaccharides on hyperlipidemia in mice by modulating the gut microbiota. MethodsNinety male C57BL/6J mice were randomized into the following groups （n=15）： control， model， simvastatin， low- （100 mg·kg^-1）， medium- （200 mg·kg^-1）， and high-dose （400 mg·kg^-1） Polygonati Odorati Rhizoma polysaccharides groups. Other groups except the control group were fed with a high-fat diet for the modeling of hyperlipidemia， and drug interventions lasted for 12 weeks. Serum levels of total cholesterol （TC）， triglycerides （TG）， low-density lipoprotein cholesterol （LDL-C）， and high-density lipoprotein cholesterol （HDL-C） were measured by an automatic biochemical analyzer. The pathological changes in the liver and epididymal fat were observed by hematoxylin-eosin staining， and lipid accumulation in the liver was assessed by oil red O staining. The gut microbiota was analyzed by 16S rRNA gene sequencing. ResultsCompared with the control group， the model group exhibited an increase in body weight （P<0.01）， along with marked elevations in serum levels of TC， TG， and LDL-C （P<0.05，P<0.01）. Furthermore， the model group showcased increase in the liver index and epididymal fat coefficient （P<0.05）， increased liver fat accumulation， enlargement of adipocytes in the epididymal fat， decreases in both alpha and beta diversity of the gut microbiota， and an increase in the relative abundance of Allobaculum （P<0.01）. Compared with the model group， Polygonati Odorati Rhizoma polysaccharides suppressed the increase in body weight （P<0.01）， lowered the serum levels of TC， TG， and LDL-C （P<0.05，P<0.01）， reduced the liver index and epididymal fat coefficient （P<0.05）， alleviated liver fat accumulation， and decreased the size of adipocytes in the epididymal fat. Furthermore， it enhanced the alpha and beta diversity of the gut microbiota in mice， reduced the relative abundance of Allobaculum， Erysipelotrichaceae， and Clostridium （P<0.01）， and increased the relative abundance of Akkermansia and Blautia （P<0.01）. ConclusionPolygonati Odorati Rhizoma polysaccharides can ameliorate hyperlipidemia induced by a high-fat diet in mice by regulating the diversity and composition of the gut microbiota.

Objective: To explore the value of body measurement indicators in screening for metabolic syndrome (MS), so as to provide the basis for early detection and prevention of MS. Methods: The individuals who were 18 years old or above and underwent physical examinations at a tertiary hospital of Xinjiang Uygur Autonomous Region were selected using the convenience sampling method. Demographic information, lifestyle, waist circumference (WC) and blood biochemical indicators were collected through questionnaire surveys, physical examinations and laboratory tests. The associations of WC, waist-to-hip ratio (WHR), waist-to-height ratio (WHtR), body roundness index (BRI), abdominal volume index (AVI), lipid accumulation product (LAP) and visceral adiposity index (VAI) with MS were analyzed using a multivariable logistic regression model. The screening values of these body measurement indicators for MS were assessed by receiver operating characteristic (ROC) curves. Results: A total of 37 921 individuals were recruited, including 20 666 males (54.50%) and 17 255 females (45.50%), and had a median age of 41.00 (interquartile range, 20.00) years. There were 7 988 cases of MS, with a detection rate of 21.06%. Multivariable logistic regression analysis showed that WC, WHR, LAP and VAI were statistically associated with MS (all P<0.05), and the risk of MS increased with the levels of these indicators (all Ptrend<0.05), after adjusting for confounding factors (gender, age, lifestyle, etc.). The area under the ROC curve (AUC) of LAP for screening MS was the highest among single indicators, at 0.930 (95%CI: 0.927-0.933), and the optimal cut-off value was 43.13, Youden's index was 0.720, the sensitivity was 88.01%, and the specificity was 84.04%. The combined indicators of WC×VAI for screening MS had the highest AUC, which was 0.937 (95%CI: 0.935-0.939), and the optimal cut-off value was 0.17, Youden's index was 0.730, the sensitivity was 91.88%, and the specificity was 81.07%. The DeLong test showed that the AUC of WC×VAI for screening MS was higher than that of WC, WHR, LAP and VAI, respectively (all P<0.05). Conclusion The value of combining WC and VAI for screening MS is higher than other body measurement indicators.

Objective: To investigate the prevalence and influencing factors of dyslipidemia among residents in Changzhou City, Jiangsu Province, so as to provide insights into improving prevention and control strategies of dyslipidemia. Methods: Permanent residents aged 35 to 75 years were recruited based on the Early Screening and Comprehensive Intervention Project for High-risk Populations of Cardiovascular Disease in Changzhou City from 2016 to 2023. Demographic information, body mass index (BMI), total cholesterol (TC), triglycerides (TG), low-density lipoprotein cholesterol (LDL-C) and high-density lipoprotein cholesterol (HDL-C) were investigated through questionnaire surveys, physical examinations and laboratory tests, and the prevalence of dyslipidemia were analyzed. Factors affecting dyslipidemia were identified using a multivariable logistic regression model. Results: A total of 22 447 residents were surveyed, including 9 142 males (40.73%) and 13 305 females (59.27%), and had a median age of 57.00 (interquartile range, 18.00) years. There were 7 535 cases of dyslipidemia, with a prevalence rate of 33.57%. The prevalence rates of low HDL-C, high TG, high TC, and high LDL-C were 22.27%, 15.89%, 4.06% and 2.27%, respectively. Multivariable logistic regression analysis showed that the residents who were male (OR=1.780, 95%CI: 1.645-1.924), had more than 50 000 yuan of annual household income (OR=1.215, 95%CI: 1.142-1.293), had higher educational level (junior high school/senior high school/technical secondary school, OR=1.138, 95%CI: 1.047-1.237; junior college and above, OR=1.232, 95%CI: 1.095-1.386), smoked frequently (OR=1.504, 95%CI: 1.369-1.653), were overweight (OR=1.763, 95%CI: 1.650-1.885) or obese (OR=2.351, 95%CI: 2.149-2.572), had hypertension (OR=1.478, 95%CI: 1.384-1.579) and diabetes (OR=1.706, 95%CI: 1.586-1.835) had a higher risk of dyslipidemia; while the residents who consumed alcohol at 4 times per week and more (OR=0.619, 95%CI: 0.557-0.688) had a lower risk of dyslipidemia. Conclusions The main types of dyslipidemia are low HDL-C and high TG among residents aged 35 years and above in Changzhou City. The prevalence of dyslipidemia is mainly associated with gender, annual household income, educational level, smoking, alcohol consumption, BMI, hypertension and diabetes.

The paper reported a case of super-elderly patient with treatment-resistant depression who underwent modified electroconvulsive therapy （MECT）. The patient was an 87-year-old female presented to the hospital with an 8-year history of depressive disorder marked by intermittent episodes， who exhibited poor response to various antidepressants while achieved a significant improvement after receiving MECT. In the past two years， the patient experienced a recurrence of depression following life stress events. The condition showed improvement with the administration of MECT. However， after discontinuation of MECT， the depression relapsed multiple times， prompting rehospitalization for continued MECT to sustain clinical benefits. The patient demonstrated overall tolerable adherence to MECT. Based on research of domestic and international， this paper explored treatment options for super-elderly patients with treatment-resistant depression， aiming to provide insights into the application of MECT in the management of depression among super-elderly patients with depression. ［Funded by National Key Research and Development Project （number， 2019YFC0118502）］

ObjectiveTo investigate the etiology and clinical features of intrahepatic cholestasis and the diagnostic value of whole exome sequencing （WES） through a retrospective analysis of the medical history， pathological results， and gene sequencing data of 62 patients with unexplained intrahepatic cholestasis. MethodsA retrospective analysis was performed for the clinical data of 480 patients who underwent WES due to unexplained liver function abnormalities in Nanjing Second Hospital from January 2017 to December 2023， among whom 62 patients with unexplained intrahepatic cholestasis were selected based on laboratory data， and a confirmed diagnosis was made based on imaging data， pathological findings， and gene sequencing data. The patients with unexplained intrahepatic cholestasis were analyzed in terms of demographic features， clinical manifestation， etiology spectrum， and genetic profile. ResultsA total of 62 patients with unexplained intrahepatic cholestasis were included， among whom there were 35 male patients and 27 female patients， with a median age of 42 （7 — ‍77） years. WES was used to make a definite diagnosis in 21 patients （33.87%）， among whom the patients with familial intrahepatic cholestasis accounted for the highest proportion of 52.38% （11/21）； genetic metabolic disorders were excluded by WES in 34 patients， with drug-induced liver injury and sepsis-associated liver injury accounting for the highest proportion of 55.88% （19/34）， followed by primary biliary cholangitis and primary sclerosing cholangitis accounting for 20.59% （7/34） and intrahepatic bile duct stones accounting for 17.65% （6/34）， while the patients with a lack of confirmed diagnosis accounted for 11.29% （7/62）. A total of 21 novel mutation sites which were not reported in previous articles were identified in this study. ConclusionGenetic metabolic disorders constitute a significant proportion of unexplained intrahepatic cholestasis， and WES plays a crucial role in the diagnosis of unexplained intrahepatic cholestasis.

Objective: To investigate the association of physical activity and screen time with overweight and obesity among children and adolescents with special needs in Tianjin, so as to provide scientific evidence for childhood obesity prevention and intervention measures in the population. Methods: From January 2022 to June 2024, 296 children and adolescents with intellectual disabilities and autism spectrum disorders aged 2-18 years were recruited from special education schools and institutions in Tianjin. Height and weight were measured, and a standardized questionnaire was used to assess physical activity and screen time. Binary Logistic regression analysis was carried out to investigate the association of physical activity and screen time with overweight and obesity. Results: The prevalence of overweight and obesity among children and adolescents with special needs in Tianjin were 17.2% and 21.6%, respectively, and the combined prevalence of overweight and obesity was 38.9%. The median of moderatetovigorous physical activity (MVPA) time was 0.20 h/d, and physical activity sufficiency rate was 7.8%. The median of screen time was 1.79 h/d, and the screen time compliance rate was 68.2%. The binary Logistic regression results showed that lower levels of MVPA time and increased screen time were associated with a higher risk of overweight and obesity among children and adolescents with special needs [OR(95%CI)=1.80(1.06-3.07), 2.40(1.42-4.07),P<0.05]. Conclusions Insufficient physical activity and excessive screen time are associated with an increased risk of overweight and obesity among children and adolescents with special needs. Therefore, comprehensive intervention measures should be implemented as early as possible to prevent and reduce the incidence of overweight and obesity in this population.

Objective: To explore the association between mediterranean diet (MD) patterns and dental caries among children and adolescents with neurodevelopmental disorders (NDD), so as to provide a basis for developing scientific anti caries strategies related to diet. Methods: From December 2021 to June 2024, a questionnaire survey, a three day 24 hour dietary review survey, oral health examination, physical development measurement and Childhood Autism Rating Scale (CARS) evaluation were conducted involving 147 children and adolescents aged 2-22 years with NDD from nine special education schools and rehabilitation institutions in Tianjin. Group comparisons were carried out using the Mann-Whitney U test, Chi-square test, or Fisher s exact probability method. The correlation between dietary quality and dental caries was analyzed by adopting multiple linear regression analysis and restricted cubic spline. Results: There were 46 children and adolescents (31.3%) in the non dental caries group and 101 children and adolescents (68.7%) in the dental caries group. The number of decayed missing and filled teeth (dmft) was 2.0 (4.0), and the MD score was 4.0 (2.0) points. There were 62 children and adolescents (42.2%) in the low MD scores group and 85 children and adolescents (57.8%) in the high MD scores group. There was no significant difference in MD scores between NDD children in the non dental caries group and those in the dental caries group [nondental caries group:4.0(2.0), dental caries group:4.0(2.0), Z= -0.14, P >0.05]. The MD scores and dmft exhibited increasing and then decreasing trend ( P total =0.02, P non lineary = 0.04 ). Children and adolescents with NDD in the MD high scores group had a lower number of dmft than those in the MD low scores group ( β= -2.00 , 95%CI =-3.39 to -0.62, P <0.05). However, in children and adolescents with NDD and CARS scores ≥30, the above association was insignificant ( β=-0.63, 95%CI=-0.29-0.15, P >0.05). Conclusion Children and adolescents with NDD who have dietary patterns similar to the Mediterranean diet, are found to have fewer dental caries, and this is observed among those with no or mild symptoms of autism spectrum disorder.

Objective: To explore the longitudinal associations between dietary macronutrients and lung function in schoolaged children, so as to provide the nutritional research evidence for promoting children s lung health. Methods: In November 2021, two primary schools located in Chengdu, Sichuan Province were selected from the Southwest China Childhood Nutrition and Growth (SCCNG) cohort by a stratified cluster random sampling method, enrolling a total of 1 112 school aged children aged 8 to 13 years. At baseline, the dietary and sociodemographic characteristics of the children were assessed. One year later, the forced vital capacity (FVC) of the children was measured and converted into Z scores (FVC- Z ), while the vital capacity index (VCI) was also calculated. Generalized linear regression analysis was employed to examine the associations between dietary macronutrients and lung function, considering interactions with gender and age, followed by stratified analysis. Results: After adjusting for confounding factors, the analysis results of the generalized linear regression model showed that the carbohydrate energy ratio was negatively correlated with FVC- Z ( β =-0.02) and VCI ( β =-0.16), while the fat energy ratio showed a positive correlation with FVC- Z ( β =0.03) and VCI ( β =0.23) ( P <0.05). The protein energy ratio was positively correlated with FVC- Z ( β =0.09) and VCI ( β =0.60) specifically in girls ( P <0.05). Additionally, there was an interaction effect of age on the associations between macronutrients and lung function ( P <0.01); in children aged 8-9 and 10-11, the carbohydrate energy supply ratio was negatively correlated with FVC- Z ( β =-0.04, -0.03) and VCI ( β =-0.29, -0.21), and fat energy supply ratio was positively correlated with FVC- Z ( β =0.07, 0.05) and VCI ( β =0.46, 0.32) ( P <0.05). Conclusions There are age and sex differences in the association of dietary macronutrients with lung function, with a low carbohydrate, high fat diet promoting lung function in children. Additionally, protein intake appears to have a positive influence on the lung function of girls. The early school age period may represent a critical window for dietary interventions aimed at promoting lung health.

Objective: To explore the association between vitamin D levels and sleep in children and adolescents，so as to provide a reference for promoting the sleep health of children and adolescents. Methods: From October to December, 2021, 4 827 primary and middle school students aged 6-17 in Shenzhen were selected by multistage cluster random sampling method, and their demographic information, family background, lifestyle and sleep status were obtained by facetoface questionnaire survey, and their fasting venous blood in the morning was collected to detect the serum 25(OH)D level. The relationship between serum vitamin D level and sleep characteristics was analyzed by binary Logistic regression, and stratified analysis was carried out according to gender. Results: The proportion of vitamin D deficiency was 41.1%, and the proportion of sleep deficiency was 19.4%. With the increase of vitamin D level, daily sleep duration of children and adolescents tended to increase (r=0.10,P<0.01). After adjusting for covariates such as gender and age, it was found that children and adolescents with insufficient vitamin D levels were more likely to experience sleep insufficiency, social jetlag, and late sleep on weekdays, with ORs being 1.32(95%CI=1.12-1.56), 1.35(95%CI=1.19-1.54), and 1.26(95%CI=1.05-1.52)(P<0.05). Sexstratified analysis showed that, among boys, vitamin D deficiency was associated with sleep deficiency, social jetlag, and late bedtime on weekdays and weekends[OR(95%CI)=1.42(1.14-1.77),1.25(1.04-1.49),1.39(1.06-1.82),1.86(1.19-2.92),P<0.05]. In girls, however, serum vitamin D levels were only associated with social jetlag with OR being 1.47 (95%CI=1.21-1.79, P<0.05). Conclusion Vitamin D levels are associated with various sleep characteristics in children and adolescents, with this association being more pronounced among boys.
