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.

OBJECTIVE To explore the effect and mechanism of Zexie tang （ZXT） on reducing lipid accumulation through network pharmacology， and compare the difference of traditional decoction versus formula granules. METHODS The active components and targets of ZXT were identified using TCMSP and SwissTargetPrediction databases. GeneCards， OMIM， DisGeNET and TTD databases were used to analyze the related targets of non-alcoholic fatty liver disease （NAFLD）； protein-protein interaction network model was constructed by String database；“ ZXT-NAFLD target-pathway” network diagram was constructed by using CytoScape software； target enrichment analysis was performed by using Metascape platform. Fat accumulation model of human hepatocellular carcinoma HepG2 cells was established to observe the effects of traditional decoction and formula granules of ZXT on lipid accumulation of cells. RESULTS Alisol B， alisol C， 1-monolinolein and alisol B monoacetate were the key active components of ZXT in the treatment of NAFLD. The core targets included MDM2， MAPK1， PIK3CB， PRKCQ and MAPK14， etc. The core signaling pathways included endocrine resistance， insulin resistance and Th17 cell differentiation. Compared with model group， except for the Zexie formula granules group and Baizhu formula granules group， the absorbance values in all other administration groups were significantly decreased （P＜0.01）； the absorbance value of Baizhu traditional decoction group was significantly higher than that of ZXT traditional decoction group （P＜0.01）； the absorbance values of Zexie formula granule group and Baizhu formula granule group were significantly higher than that of ZXT formula granule group （P＜0.01）； the absorbance value of Zexie formula granule group was significantly higher than that of Zexie traditional decoction group （P＜0.01）； the absorbance value of Baizhu formula granule group was significantly higher than that of Baizhu traditional decoction group （P＜0.01）. CONCLUSIONS ZXT reduces lipid accumulation of human hepatocellular carcinoma cells through multiple components， multiple target and multiple pathways， and its traditional decoction and formula granules exhibit slightly different lipid-lowering effects.

Diabetic nephropathy(DN)is one of the most important complications of diabetes.Its pathogenesis is com-plex and has not been fully elucidated.Epithelial-mesenchymal transition(EMT)plays an important role in the development of DN.Relevant data show that glycogen synthesis kinase-3β(GSK-3β)participates in the process of EMT through multiple sig-naling pathways and affects the occurrence and progression of DN.This article reviews the research progress of GSK-3β in-volved in EMT in DN.

Objective:To explore the relation of childhood trauma to marital satisfaction in divorce partici-pants and the mediating role of conflict resolution styles.Methods:Totally 305 divorced participants were selected by convenient sampling and evaluated with the Childhood Trauma Questionnaire(CTQ),the marital satisfaction subscale and the conflict resolution subscale of Olson Enrich Marital Inventory(ENRICH).Results:The detection rate of childhood trauma among the divorced participants was 67.5％.The CTQ scores were negatively correlated with the scores of conflict resolution styles and marital satisfaction(r=-0.14,-0.25,Ps＜0.05).The conflict resolution styles mediated entirely the relationship between childhood trauma and marital satisfaction in divorced participants,with a total effect of-0.06(95％CI:-0.11--0.01).Conclusion:It suggests that childhood trau-ma of divorcing participants may be associated with marital satisfaction and conflict resolution styles.

OBJECTIVE To study the differences in toxicity between intravenous(iv)administration and aqueous solution exposure of Dichroa alkali salt(DAS)in zebrafish.METHODS ① Well-devel-oped zebrafish larvae of 2 d post fertilization(2 dpf)were randomly divided into the normal control(no treatment),solvent control(saline,iv),and DAS groups(0.125,0.25,0.50,1.00 and 2.00 mg·kg-1,iv)before being observed for 3 consecutive days after administration.A heart rate of 0 was determined as death of zebrafish,and the mortality rate,maximum non-lethal dose(MNLD),and 10 percent lethal dose(LD10)were calculated.The incidence of venous sinus congestion,pericardial edema,slowing heart rate and blood flow of zebrafish in the 0.50 and 2.00 mg·kg-1 groups were observed and calculated by somatoscopic microscopy at 4 h after drug administration.Zebrafish larvae were iv given DAS at doses of 0.041,0.136,0.412,and 0.452 mg·kg-1 while the malformation phenotypes of zebrafish larvae development were observed under a stereomicroscope for 3 consecutive days,including pericardial edema,abnormal heart rate,slow blood flow,loss of circulation,eye abnormalities,brain malforma-tions,jaw abnormalities,loss/degeneration of the liver,delayed yolk sac absorption,intestinal abnormal-ities,abnormal body coloration,body edema,curvature of the trunk/tail/nodal cord and muscle degener-ation before the incidence was calculated.②Zebrafish larvae were randomly divided into a normal control group and DAS aqueous solution exposure groups at concentrations of 2.5,5.0,10.0,25.0,50.0,75.0,and 100.0 mg·L-1,observed for 3 d until the mortality rate,LD10,and MNLD were calculated.Zebrafish were exposed to DAS aqueous solutions at concentrations of 0.32,1.06,3.20,and 11.00 mg·L-1,and the malformation phenotypes of zebrafish larvae development were observed under a stereomicro-scope for 3 consecutive days to calculate the incidence.RESULTS ① The MNLD and LD10 of DAS iv administered to zebrafish larvae were 0.412 and 0.452 mg·kg-1,respectively.Compared with the solvent control group,4 h after DAS iv administration,the incidence of sinus congestion,slow heart rate and pericardial edema in the 0.50 and 2.00 mg·kg-1 groups significantly increased(P<0.05,P<0.01),so was the incidence of slow blood flow in the 2.00 mg·kg-1 group(P<0.01).The rate of delayed yolk sac absorption was significantly increased in the 0.041,0.136,0.412,and 0.452 mg·kg-1 groups(P<0.05,P<0.01),so was the mortality rate in the 0.452 mg·kg-1 group(P<0.05),with pericardial edema observed in the dead zebrafish.② The MNLD and LD10 of DAS aqueous solution exposure for zebrafish larvae were 3.20 and 11.00 mg·L-1,respectively.Compared with the normal control group,the incidence of decreased heart rate and slow blood flow was significantly increased in the 3.20 and 11.00 mg·L-1 groups(P<0.01),so was the incidence of significantly darkened intestines in the 1.06,3.20,and 11.00 mg·L-1 groups(P<0.01).The incidence of delayed yolk sac absorption was significantly increased in the 0.32,1.06,3.20,and 11.00 mg·L-1 groups(P<0.05,P<0.01),so was the incidence of trunk curvature and lower jaw malformation in the 11.00 mg·L-1 group(P<0.01).CONCLUSION The toxic phenotypes of DAS are different between iv administration and aqueous solution exposure in zebrafish larvae.DAS aqueous solution exposure can not only lead to slow heart rate,slow blood rheology,delayed yolk sac absorption and intestinal blackening,but also induce neurodevelopmental toxicity.However,iv adminis-tration can effectively ward off significant gastrointestinal damage and neurodevelopmental toxicity.

The outbreak of COVID-19 as an acute communicable disease has also changed the epidemiological status of diabetes mellitus and other noncommunicable chronic diseases. During the COVID-19 epidemic period, it was observed that there were increased morbidity of diabetes, difficulties in blood sugar control and increased acute complications for diabetic patients. This may be attributed to lifestyle changes during the epidemics, such as the reduced exercise time and increased sedentary time, more snacks and sugary food intake, as well as anxiety and depression. However, it is not known the long-term impact of COVID-19 epidemic on the management of diabetic patients, so it is necessary to closely monitor the exposed diabetic patients in the future.

【Objective】 To construct a prediction model of severe obstructive sleep apnea (OSA) risk in the general population by using nomogram in order to explore the independent risk factors of severe OSA and guide the early diagnosis and treatment. 【Methods】 We retrospectively enrolled patients who had been diagnosed by polysomnography and divided them into training and validation sets at the ratio of 7∶3. Patients were divided into severe OSA group and non-severe OSA group according to apnea hypopnea index (AHI)>30. Variables entering the model were identified by least absolute shrinkage and selection operator regression model (Lasso), and logistic regression (LR) method. Then, multivariable logistic regression analysis was used to establish the nomogram, and the area under the receiver operating characteristic curve (AUC) was used to evaluate the discriminative properties of the nomogram model. Finally, we conducted decision curve analysis (DCA) of nomogram model, STOP-Bang questionnaire and Berlin questionnaire to assess clinical utility. 【Results】 Through single factor and multiple factor logistic regression analyses, the independent risk factors for severe OSA were screened out, including moderate and severe sleepiness, family history of hypertension, history of smoking, drinking, snoring, history of suffocation, sedentary lifestyle, male, age, body mass index (BMI), waist and neck circumference. Lasso logistic regression identified smoke, suffocation time, snoring time, waistline, Epworth sleepiness scale (ESS) and BMI as predictive factors for inclusion in the nomogram. The AUC of the model was 0.795 [95% confidence interval (CI): 0.769-0.820] . Hosmer-Lemeshow test indicated that the model was well calibrated (χ²=3.942, P=0.862). The DCA results on the visual basis confirmed that the nomogram had superior overall net benefits within a wide, practical threshold probability range which displayed the nomogram was higher than that of STOP-Bang questionnaire and Berlin questionnaire, which is clinically useful. The Clinical Impact Curve (CIC) analysis showed the clinical effectiveness of the prediction model when the threshold probability was greater than 82% of the predicted score probability value. The prediction model determined that the high-risk population with severe OSA was highly matched with the actual population with severe OSA, which confirmed the high clinical effectiveness of the prediction model. 【Conclusion】 The model performed better than STOP-Bang questionnaire and Berlin questionnaire in predicting severe OSA and can be applied to screening. And it can be helpful to the early diagnosis and treatment of OSA in order to reduce social burden.

Hiatal hernia (HH) is a prevalent medical condition characterized by the protrusion of abdominal contents into the thoracic cavity through an enlarged diaphragmatic esophageal hiatus. The most common clinical manifestations of HH include acid reflux, heartburn, belching, coughing, and chest pain. Currently, there is a lack of standardized comprehensive treatment protocols for different types of HH, presenting significant challenges in their clinical management. In light of this, individualized treatment approaches should be followed by surgical practitioners when dealing with HH, in order to formulate the most appropriate clinical treatment plan tailored to each patient′s specific circumstances.

Objective:To analyze the risk factors for heart failure in patients with hemodialysis, and to construct a nomogram model.Methods:The clinical data of 218 patients with hemodialysis in Xianyang Central Hospital from January 2021 to April 2022 were retrospectively analyzed. Among them, 83 cases developed heart failure (heart failure group), and 135 cases did not develop heart failure (control group). The relevant clinical data were recorded, including age, sex, body mass index, disease duration, concurrent infection, blood calcium, blood phosphorus, soluble CD 146 (sCD 146), soluble growth-stimulated expression gene 2 protein (sST2), N-terminal brain natriuretic peptide precursor (NT-proBNP), time-averaged urea concentration (TACurea), tumor necrosis factor α (TNF-α), blood creatinine and 24 h urine volume. Receiver operating characteristic (ROC) curve was used to analyze the efficacy of each index in predicting heart failure in patients with hemodialysis. Multivariate Logistic regression was used to analyze the independent risk factors of heart failure in patients with hemodialysis. R language software 4.0 "rms" package was used to construct the nomogram model for predicting the heart failure in patients with hemodialysis, the calibration curve was internally validated, and the decision curve was used to evaluate the predictive efficacy of the nomogram model. Results:There were no statistical difference in gender composition, age, body mass index, disease duration, 24 h urine volume and blood creatinine between the two groups ( P>0.05); the rate of concurrent infection, blood phosphorus, sCD 146, sST2, NT-proBNP, TNF-α and TACurea in heart failure group were significantly higher than those in control group: 39.76% (33/83) vs. 8.89% (12/135), (1.53 ± 0.34) mmol/L vs. (1.27 ± 0.24) mmol/L, (43.60 ± 10.24) μmol/L vs. (28.08 ± 7.99) μmol/L, (49.00 ± 9.41) μg/L vs. (34.53 ± 8.05) μg/L, (38.57 ± 6.79) μg/L vs. (29.72 ± 5.64) μg/L, (5.18 ± 0.92) μg/L vs. (4.07 ± 1.13) μg/L and (24.28 ± 4.37) mmol/L vs. (17.96 ± 2.52) mmol/L, the blood calcium was significantly lower than that in control group: (1.95 ± 0.36) mmol/L vs. (2.31 ± 0.39) mmol/L, and there were statistical differences ( P<0.01). ROC curve analysis result showed that the optimal cut-off values of blood calcium, blood phosphorus, sCD 146, sST2, NT-proBNP, TNF-α and TACurea for heart failure in patients with hemodialysis were 2.01 mmol/L, 1.42 mmol/L, 34.15 μmol/L, 40.37 μg/L, 35.37 μg/L, 4.33 μg/L and 20.74 mmol/L. Multivariate Logistic regression analysis result showed that the blood calcium (≤2.01 mmol/L), blood phosphorus (>1.42 mmol/L), sCD 146 (>34.15 μmol/L), sST2 (>40.37 μg/L), NT-proBNP (>35.37 μg/L), TNF-α (>4.33 μg/L) and TACurea (>20.74 mmol/L) were independent risk factors for heart failure in patients with hemodialysis ( OR = 1.183, 1.582, 1.915, 1.105, 1.459, 1.347 and 1.717; 95% CI 1.102 to 1.191, 1.274 to 1.868, 1.716 to 2.105, 1.072 to 1.141, 1.225 to 1.703, 1.132 to 1.574 and 1.482 to 1.935; P<0.05 or <0.01). The blood calcium, blood phosphorus, sCD 146, sST2, NT-proBNP, TNF-α and TACurea were used as predictors to construct a nomogram model for predicting heart failure in patients with hemodialysis. Internal validation result showed that the nomogram model predicted the heart failure with good concordance in patients with hemodialysis (C-index = 0.811, 95% CI 0.675 to 0.948); the nomogram model predicted the heart failure in patients with hemodialysis at a threshold>0.18, provided a net clinical benefit, and all had higher clinical net benefits than blood calcium, blood phosphorus, sCD 146, sST2, NT-proBNP, TNF-α and TACurea. Conclusions:The nomogram model constructed based on blood calcium, blood phosphorus, sCD 146, sST2, NT-proBNP, TNF-α and TACurea has better clinical value in predicting the heart failure in patients with hemodialysis.
