Objective: To explore the impact of sleep quality, experience of childhood maltreatment, and their interaction on depressive symptoms among middle school students, so as to provide the reference for early intervention of depressive symptoms among middle school students. Methods: From September to December 2023, a questionnaire survey was conducted among 1 231 students from two secondary schools in Harbin, Heilongjiang Province by a convenient sampling method. The survey included general demographic information, Childhood Trauma Questionnaire Short Form, Pittsburgh Sleep Quality Index and Short Version of Center for Epidemiological Studies Depression Scale. The Chi square test was used to analyze the differences in depressive symptom, sleep quality and childhood maltreatment among students with different demographic characteristics. Correlation analysis was conducted using Logistic regression, and interaction analysis was performed by both additive and multiplicative interaction models. Results: The detection rate of depressive symptoms among middle school students was 22.7%, and the rate for high school students (35.2%) was significantly higher than that for middle school students (17.0%) ( χ 2=50.35, P <0.01). The detection rates of depressive symptoms among middle school students with a history of childhood maltreatment and poor sleep quality were 45.8% and 44.0%, respectively. Multivariate Logistic regression analysis showed that compared to students without a history of childhood maltreatment, students with a history of childhood maltreatment had a higher risk of depressive symptoms ( OR =4.49，95% CI =3.31~ 6.09 , P <0.01);students with poor sleep quality had a higher risk of depressive symptoms than students with good sleep quality ( OR = 5.99，95% CI =4.37~8.22, P <0.01).The interaction results showed that the presence of childhood maltreatment and poor sleep quality had an additive interaction on the occurrence of depression in middle school students. Compared with students without childhood maltreatment and having good sleep quality, students with childhood maltreatment and poor sleep quality had a 22.49 times higher risk of developing depression ( OR =22.49，95% CI =14.22~35.59, P <0.01). Conclusion Depressive symptoms among middle school students are associated with childhood maltreatment and poor sleep quality, and there is an additive interaction between childhood maltreatment and poor sleep quality on the impact of depressive symptoms.

ObjectiveTo establish the specific chromatogram and quantitative analysis of multi-components by single-marker（QAMS） based on linear calibration using two reference substances（LCTRS）， explore the consistency between Hedyotis Herba dispensing granules and standard decoction， and evaluate the quality of the dispensing granules. MethodsHigh performance liquid chromatography（HPLC） specific chromatogram was established based on 15 batches of Hedyotis Herba standard decoction and 10 batches of the dispensing granules， and LCTRS was used to locate chromatographic peaks. The actual retention times of 7 characteristic peaks in the specific chromatogram was measured on 24 different types of C₁₈ columns， taking deacetyl asperulosidic acid and asperulosidic acid as the dual standard compounds， the retention times of the other 5 characteristic peaks were predicted and validated. Based on this， QAMS was developed to determine the contents of four components（deacetyl asperulosidic acid， deacetyl asperulosidic acid methyl ester， asperulosidic acid， and p-coumaric acid）. Then， the relative correction factors of deacetyl asperulosidic acid， deacetyl asperulosidic acid methyl ester and p-coumaric acid were calculated using the reference peak of asperulosidic acid in the dual standard compounds， and each component was quantified accordingly. Finally， the consistency between the dispensing granules and standard decoction was assessed by taking extract rate of the standard decoction， consistency of the specific chromatograms， contents and transfer rates of the indicator components as indexes， and the quality of the dispensing granules was evaluated. ResultsThere were 7 common peaks in the characteristic chromatogram of samples of Hedyotis Herba standard decoction and the dispensing granules， and four of them were identified by reference standards， namely deacetyl asperulosidic acid（peak 1）， deacetyl asperulosidic acid methyl ester（peak 3）， asperulosidic acid（peak 6） and p-coumaric acid（peak 7）. The similarity between the dispensing granules and the standard decoction was >0.9. The absolute deviation in the predicted retention time for each component by LCTRS was lower than that of the relative retention time method. The extract rate of the 15 batches of Hedyotis Herba standard decoction ranged from 7.89% to 14.60%， the contents of deacetyl asperulosidic acid， deacetyl asperulosidic acid methyl ester， asperulosidic acid and p-coumaric acid were 6.62-19.70， 3.83-17.99， 1.57-6.69， 1.62-4.52 mg·g^-1， and the transfer rates of these components from decoction pieces to the standard decoction were 22.89%-39.60%， 34.03%-62.24%， 24.25%-43.70%， and 40.58%-73.71%， respectively. The extract rate， index component contents and transfer rates from decoction pieces to the three batches of Hedyotis Herba dispensing granules（P1-P3）， produced by manufacturer A， were similar to those of the standard decoction prepared from the same batch of decoction pieces， and all fell within the specified range. The contents of the 4 indicator components in 7 batches of the dispensing granules（P4-P10） from manufacturers B-E were all within the range of the content converted from the standard decoction based on the quantity of the dispensing granules. ConclusionThe established specific chromatogram and QAMS based on LCTRS are reasonable and reliable. Based on the evaluation indicators of standard decoction yield， consistency of specific chromatograms， contents and transfer rates of the four index components， the 10 batches of Hedyotis Herba dispensing granules from various manufacturers have exhibited good consistency with the standard decoction， indicating that the current production process is relatively reasonable.

Background: s/Aims: Non-invasive models stratifying clinically significant portal hypertension (CSPH) are limited. Herein, we developed a new non-invasive model for predicting CSPH in patients with compensated cirrhosis and investigated whether carvedilol can prevent hepatic decompensation in patients with high-risk CSPH stratified using the new model. Methods: Non-invasive risk factors of CSPH were identified via systematic review and meta-analysis of studies involving patients with hepatic venous pressure gradient (HVPG). A new non-invasive model was validated for various performance aspects in three cohorts, i.e., a multicenter HVPG cohort, a follow-up cohort, and a carvediloltreating cohort. Results: In the meta-analysis with six studies (n=819), liver stiffness measurement and platelet count were identified as independent risk factors for CSPH and were used to develop the new “CSPH risk” model. In the HVPG cohort (n=151), the new model accurately predicted CSPH with cutoff values of 0 and –0.68 for ruling in and out CSPH, respectively. In the follow-up cohort (n=1,102), the cumulative incidences of decompensation events significantly differed using the cutoff values of <–0.68 (low-risk), –0.68 to 0 (medium-risk), and >0 (high-risk). In the carvediloltreated cohort, patients with high-risk CSPH treated with carvedilol (n=81) had lower rates of decompensation events than non-selective beta-blockers untreated patients with high-risk CSPH (n=613 before propensity score matching [PSM], n=162 after PSM). Conclusions Treatment with carvedilol significantly reduces the risk of hepatic decompensation in patients with high-risk CSPH stratified by the new model.

Objective: To investigate the factors affecting carotid plaques among perimenopausal women, so as to provide the basis for the prevention and early intervention of cardiovascular diseases in perimenopausal women. Methods: Perimenopausal women aged 40-60 who underwent health check-ups at Xingtai People's Hospital from January 2022 to January 2023 were selected as subjects by convenient sampling method. Demographic information, lifestyle, waist-to-hip ratio, and blood biochemical indicators were collected through questionnaire surveys, physical examinations, and laboratory tests. Carotid plaques were detected using a Doppler ultrasound diagnostic instrument. Factors affecting carotid plaques among perimenopausal women were identified using a multivariable logistic regression model. Results: Totally 2 146 perimenopausal women were surveyed, with an age of (50.04±5.82) years. Carotid plaques were detected in 525 cases, with a detection rate of 24.46%. Multivariable logistic regression analysis showed that older age (45-<50 years old, OR=1.474, 95%CI: 1.062-2.047; 55-60 years old, OR=1.779, 95%CI: 1.276-2.481), residing in urban areas (OR=1.601, 95%CI: 1.079-2.376), drinking (OR=1.805, 95%CI: 1.108-2.941), hypertension (OR=1.815, 95%CI: 1.290-2.553), abnormal waist-to-hip ratio (OR=2.479, 95%CI: 1.982-3.101), and abnormal atherogenic index of plasma (OR=1.325, 95%CI: 1.064-1.650) were associated with a higher risk of carotid plaques. College degree or above (college, OR=0.659, 95%CI: 0.502-0.865; bachelor's degree or above, OR=0.517, 95%CI: 0.397-0.673), physical exercise (OR=0.621, 95%CI: 0.494-0.781) were associated with a lower risk of carotid plaques. Conclusion The carotid plaques among perimenopausal women mainly affected by age, place of residence, educational level, alcohol consumption, physical exercise, hypertension, waist-to-hip ratio and atherogenic index of plasma.

OBJECTIVE: Coptis chinensis (Huanglian in Chinese, HL) is commonly utilized in clinical settings to counteract dyslipidemia in patients with hot syndrome. Its lipid-reducing efficacy has been consistently demonstrated in high-fat diet (HFD)-induced hyperlipidemic animal models. However, whether HL's efficacy differs in HFD-fed animals with hot or cold syndromes remains unclear. This study aims to discern the variations in the anti-hyperlipidemic effects of HL in HFD-fed mice with hot or cold syndromes. METHODS: HFD-induced C57BL/6 mice were subjected to cold or hot syndrome via two weeks of ice water (0 °C) and levothyroxine sodium (240 µg/kg) treatment, respectively. Then, an aqueous extract of HL was administered to the mice via oral gavage over the following four-week period. Lipid levels in the serum and liver were gauged to determine the lipid-reducing effects of HL. Furthermore, gut microbiota composition was elucidated using full-length 16S rRNA gene sequencing. RESULTS: HL notably reduced lipid levels in HFD-induced hyperlipidemic mice. Its efficacy was amplified in hyperlipidemic mice with a hot syndrome but was markedly reduced in those with a cold syndrome. HL treatment led to a decline in alpha-diversity (characterized by ACE, Chao1, Shannon and Simpson index) of the gut microbiota in both sets of mice but affected specific microbial populations based on the syndrome. Specifically, while HL led to a notable increase in Eubacterium, Robinsoniella, and Lachnoclostridium genera, along with the enhancement of Clostridium innocuum and Bacteroides thetaiotaomicron species across all conditions, it syndrome-dependently stimulated Romboutsia ilealis and Parabaceroides_sp_HGS0025 species in mice with hot syndrome. CONCLUSION HL shows stronger lipid-lowering effect on hyperlipidemic mice with hot syndrome, which is in accordance with its traditional usage in clinic. The therapeutic outcomes of HL are intrinsically tied, at least in part, to its modulatory effects on the gut microbiota, offering fresh insights into the foundational principles of traditional Chinese medicine.

Objective:To establish the reference values and growth curves of skeletal muscle mass among children in the Nanjing area.Methods:A cross-sectional study was conducted with children who underwent physical examination at the Department of Child Health Care, Children′s Hospital of Nanjing Medical University from 2020 January to 2022 September. Their height, weight, body fat mass and skeletal muscle mass were measured. Body mass index, percentage of body fat mass, percentage of skeletal muscle mass, relative skeletal muscle mass index and the ratio of skeletal muscle to body fat were calculated. The associations between skeletal muscle mass indices and physical measurements index were analyzed through the Spearman correlation test. The Mann-Kendall test was used to assess the trend for skeletal muscle mass. Generalized additive models for location, scale and shape were used to construct percentile reference values and growth curves of male and female skeletal muscle mass indices at different ages.Results:A total of 32 690 children aged 4-14 years were enrolled in this study, including 19 912 boys (60.91%). Skeletal muscle mass, percentage of skeletal muscle mass, relative skeletal muscle mass index and the ratio of skeletal muscle to body fat of boys and girls was 11.10 (8.40, 14.90) and 10.30 (7.90, 13.20) kg, 40.36% (37.01%, 43.13%) and 39.38% (36.43%, 41.88%), 6.70 (6.07, 7.52) and 6.33 (5.79, 7.00), 2.39 (1.46, 3.47) and 2.14 (1.45, 3.00) kg/m 2, respectively. Skeletal muscle mass of both boys and girls was all positively associated with weight ( r=0.97, 0.96), body mass index ( r=0.68, 0.63) and percentage of body fat mass ( r=0.40, 0.43) (all P<0.01). The reference values and growth curves showed that the percentage of skeletal muscle mass P50 ranged from 37.75%-44.61% in boys and from 36.22%-40.55% in girls. The relative skeletal muscle mass index P50 ranged from 5.80-9.68 kg/m 2 in boys and from 5.57-7.98 kg/m 2 in girls. The ratio of skeletal muscle to body fat P50 ranged from 1.86-2.67 in boys and from 1.29-2.41 in girls. There was an increasing trend with age for both boys and girls in the growth of skeletal muscle mass ( Z=4.20, 3.75, both Ptrend<0.01), and increased slightly before 9 years of age and then increased rapidly until 14 years of age in both boys and girls. Conclusions:The skeletal muscle mass indices change with age and gender during childhood. Percentile reference values for pediatric skeletal muscle mass indices can be used to evaluate the muscular growth and development in children in the Nanjing area.

Objective:To investigate the predictive value of neck circumference on cardiometabolic risk in children.Methods:This was a cross-sectional study of natural sources. As the prediction cohort, clinical data were collected from 3 443 children aged 5-14 years who underwent physical examination in the Department of Child Healthcare, Children′s Hospital of Nanjing Medical University from July 2021 to September 2022. As the validation cohort for external validation, clinical data were collected from 604 children aged 5-14 years who underwent physical examination in the Department of Child Healthcare, Children′s Hospital of Nanjing Medical University from October 2022 to March 2023. Height, weight, neck circumference, waist circumference and body composition were measured in both groups, and body mass index, neck circumference to height ratio (NHtR), waist circumference to height ratio, body fat percentage and skeletal muscle percentage were calculated. Systolic blood pressure, diastolic blood pressure, fasting blood glucose, blood lipid and uric acid and other cardiovascular and metabolic risk indicators were collected in both groups. The prediction cohort was further stratified into clustered and non-clustered groups based on the clustering of cardiometabolic risk factors (CCRF). Various variables between these 2 groups were compared using the Mann-Whitney U test. Pearson correlation and binary Logistic regression were conducted to investigate the correlations between neck circumference and cardiovascular metabolic risk factors. The accuracy of NHtR in predicting the CCRF was evaluated using the area under the curve (AUC) of receiver operating characteristic (ROC). The cutoff value was determined using the Youden index. The validation cohort was then divided into groups above and below the cutoff value, and the detection rate of CCRF between the 2 groups was compared using the χ2 test for validation .Results:In the prediction cohort of 3 443 children (2 316 boys and 1 127 girls), 1 395 (40.5%) children were overweight or obese, and 1 157 (33.6%) children had CCRF. Pearson correlation analysis revealed all significant positive correlations (all P<0.01) between neck circumference and systolic blood pressure ( r=0.47, 0.39), diastolic blood pressure ( r=0.27, 0.21), uric acid ( r=0.36, 0.30), and triglycerides ( r=0.20, 0.20) after adjusting for age in both males and females. Among both males and females, neck circumference both showed significant negative correlation (both P<0.01) with high-density lipoprotein cholesterol ( r=-0.27, -0.28), and no correlation with fasting glucose levels ( r=0.03, -0.03, both P>0.05). After adjusting for gender, age, and body fat percentage, increased body mass index, neck circumference, or waist circumference increased the risks of hypertension ( OR=1.23, 1.39, 1.07, all P<0.001), hyperuricemia ( OR=1.16, 1.23, 1.05, all P<0.001), hypertriglyceridemia ( OR=1.08, 1.16, 1.02, all P<0.01), low high-density lipoprotein cholesterol ( OR=1.10, 1.27, 1.03, all P<0.01), and the CCRF ( OR=1.51, 1.73, 1.15, all P<0.01). The areas under the ROC curves of NHtR in predicting CCRF was 0.73, with sensitivity and specificity at 0.66 and 0.71, respectively. The corresponding optimal cut-off value was 0.21. Validation with 604 children confirmed that the detection of CCRF in the NHtR≥0.21 group was 3.29 times (60.5% (112/185) vs. 18.7% (79/422), χ2=107.82, P<0.01) higher compared to the NHtR <0.21 group. Conclusions:Neck circumference is associated with cardiovascular metabolic risks such as hypertension, hyperlipidemia, hyperglycemia, and hyperuricemia in children. When the NHtR is ≥0.21, there is an increased likelihood of CCRF.

Objective To explore the effect of compound active tea of Lithocarpus litseifolius on uric acid levels and kidney function of mice with hyperuricemia nephropathy and to provide an experimental basis for the development of hyperuricemia nephropathy drugs and functional food.Methods A mouse model of hyperuricemia nephropathy was established by administering potassium oxazinate with adenine.Mice were randomly divided into common,model,positive drug(10 mg/(kg·d))and compound active tea of Lithocarpus litseifolius high-,middle-and low-dose groups(10 g/(kg ·d),3.33 g/(kg·d)and 1.11g/(kg·d),respectively).One hour after the last gavage,urine protein(UP)was measured by CBB method,urea nitrogen(UUN)was measured by urease method.Orbital blood pampling,blood was collected for uric acid(UA)analysis by enzyme ratio method,urea nitrogen(BUN)was measured by urease method.The serum contents of interleukin 6(IL-6)and tumor necrosis factor(TNF-α)were measured by ELISA.Take kidney tissue,levels of urate transporter 1(URAT1)and glucose transporter 9(GLUT9)were measured by quantitative fluorescence,kidney histopathological changes were observed by HE stainning.Results Compared with the control group,the model group's levels of UP,UUN,UA,BUN,IL-6,URAT1,ULUT9 and TNF-α were significantly increased(P＜0.01,P＜0.05),and the renal tissue structure was normal.Compared with the model group,the positive group's levels of UP,UUN,UA,BUN,IL-6 and TNF-α were significantly decreased(P＜0.01,P＜0.05),there was little glomerular atrophy or deformation in the kidneys,kidney tubular dilatation was occasionally seen,but there was no inflammatory cell infiltration.Compared with the model group,the high-dose compound active tea of Lithocarpus litseifolius group's UP,UUN,UA,BUN,IL-6,URAT1,TNF-α and GLUT9 levels were significantly decreased(P＜0.01,P＜0.05).The middle-dose compound active tea of Lithocarpus litseifolius group's UP,UUN,UA content,IL-6,URAT 1,GLUT9,BUN and TNF-αwere significantly decreased(P＜0.01,P＜0.05).The low-dose compound active tea of Lithocarpus litseifolius group's UP,UUN,UA,IL-6,URAT1,BUN,TNF-α and GLUT9 levels were significantly decreased(P＜0.01,P＜0.05).Conclusions Compound active tea of Lithocarpus litseifolius can reduce uric acid in mice with hyperuricemia nephropathy and has a certain protective effect on the kidneys.The mechanism may be related to the inhibition of uric acid reabsorption,and the specific mechanistic details should be further investigated.
