Objective: To analyze the association of mother-child interaction and screen exposure of preschool children with psychological and behavioural problems, so as to provide guidance for promoting the psychological development of preschool children. Methods: From November to December 2024, a convenience cluster sampling method was used to survey 2 977 mothers of preschool children in Daguan and Yingjiang districts of Anqing City. The Chinese Parent-Child Interaction Scale (CPCIS) was applied to evaluate the quality of mother-child interaction, and the Conners Parent Symptom Questionnaire (PSQ) was used to assess the psychological and behavioral problems of preschool children. Binary Logistic regression was applied to analyze the association of mother-child interaction, screen exposure and their combined effect on psychological and behavioral problems among preschool children. Results: The detection rate of psychological and behavioral problems among preschool children was 13.9%. Binary Logistic regression results showed that low scores of mother-child interaction ( OR=2.31, 95%CI =1.72-3.11) and high screen exposure ( OR= 1.52 , 95%CI =1.23-1.88) were higher risks for psychological and behavioral problems in preschool children; the results of the combined effect showed that preschool children in low scores of mother-child interaction and low screen exposure group ( OR=2.18, 95%CI =1.46-3.28), low scores of mother-child interaction and high screen exposure group ( OR=3.13, 95%CI =2.10- 4.65 ) had significantly higher risks of abnormal detection in psychological and behavioral problems, compared to those in the high scores of mother-child interaction and low screen exposure group respectively (all P <0.05). Conclusions Both screen exposure and mother- child interaction are associated with psychological and behavioral problems in preschool children. High quality mother-child interaction can relieve the adverse effects of screen exposure on preschool children s psychological and behavioral development.

ObjectiveTo conduct a bibliometric analysis on the research status of occupational pneumoconiosis (hereinafter referred to as "pneumoconiosis") severity assessment indicators. Methods The domestic and foreign articles on the research of pneumoconiosis severity assessment indicators were accessed from China National Knowledge Infrastructure, Wanfang Data, VIP Database, China Biomedical Literature Service System, PubMed, Cochrane Library, and Web of Science. The methodological quality evaluation and analysis of severity assessment indicators were performed with the relevant articles. Results A total of 88 relevant articles on pneumoconiosis severity assessment indicators were included. The overall evaluation of the literature with good-, moderate-, and poor-quality articles accounted for 18.18%, 69.32%, and 12.50%, respectively. The median sample size reported in each article was 86 cases. The articles reporting the stage of pneumoconiosis accounted for 81.82%, and 80.68% reported the types of pneumoconiosis which was mainly simple silicosis and coal worker's pneumoconiosis. Only 12 articles reported two or more types of pneumoconiosis. A total of 122 severity assessment indicators in four categories were reported in 88 articles, including 99 physiological and biochemical indicators, 10 imaging indicators, six symptoms and signs indicators, and seven other indicators. The articles used a single severity assessment indicator to assess the severity of pneumoconiosis accounted for 76.14%, while 23.86% of the articles used multiple severity assessment indicators, and only 5.68% of the articles selected specific severity assessment indicators for pneumoconiosis patients in different stages. Conclusion The quality of research on pneumoconiosis severity assessment is relatively low. The applicability of the combined use of severity assessment indicators is poor and confused.

Objective:To evaluate the immunogenicity, safety, and immune persistence of the sequential booster with the recombinant protein-based COVID-19 vaccine (CHO cell) in healthy people aged 18-84 years.Methods:An open-label, multi-center trial was conducted in October 2021. The eligible healthy individuals, aged 18-84 years who had completed primary immunization with the inactivated COVID-19 vaccine 3 to 9 months before, were recruited from Shangyu district of Shaoxing and Kaihua county of Quzhou, Zhejiang province. All participants were divided into three groups based on the differences in prime-boost intervals: Group A (3-4 months), Group B (5-6 months) and Group C (7-9 months), with 320 persons per group. All participants received the recombinant COVID-19 vaccine (CHO cell). Blood samples were collected before the vaccination and after receiving the booster at 14 days, 30 days, and 180 days for analysis of GMTs, antibody positivity rates, and seroconversion rates. All adverse events were collected within one month and serious adverse events were collected within six months. The incidences of adverse reactions were analyzed after the booster.Results:The age of 960 participants was (52.3±11.5) years old, and 47.4% were males (455). The GMTs of Groups B and C were 65.26 (54.51-78.12) and 60.97 (50.61-73.45) at 14 days after the booster, both higher than Group A′s 44.79 (36.94-54.30) ( P value<0.05). The GMTs of Groups B and C were 23.95 (20.18-28.42) and 27.98 (23.45-33.39) at 30 days after the booster, both higher than Group A′s 15.71 (13.24-18.63) ( P value <0.05). At 14 days after the booster, the antibody positivity rates in Groups A, B, and C were 91.69% (276/301), 94.38% (302/320), and 93.95% (295/314), respectively. The seroconversion rates in the three groups were 90.37% (272/301), 93.75% (300/320), and 93.31% (293/314), respectively. There was no significant difference among these rates in the three groups (all P values >0.05). At 30 days after the booster, antibody positivity rates in Groups A, B, and C were 79.60% (238/299), 87.74% (279/318), and 90.48% (285/315), respectively. The seroconversion rates in the three groups were 76.92% (230/299), 85.85% (273/318), and 88.25% (278/315), respectively. There was a significant difference among these rates in the three groups (all P values <0.001). During the sequential booster immunization, the incidence of adverse events in 960 participants was 15.31% (147/960), with rates of about 14.38% (46/320), 17.50% (56/320), and 14.06% (45/320) in Groups A, B, and C, respectively. The incidence of adverse reactions was 8.02% (77/960), with rates of about 7.50% (24/320), 6.88% (22/320), and 9.69% (31/320) in Groups A, B, and C, respectively. No serious adverse events related to the booster were reported. Conclusion:Healthy individuals aged 18-84 years, who had completed primary immunization with the inactivated COVID-19 vaccine 3 to 9 months before, have good immunogenicity and safety profiles following the sequential booster with the recombinant COVID-19 vaccine (CHO cell).

Objective:Non-alcoholic fatty liver disease(NAFLD)is a common metabolic disorder in overweight and obese children,and its etiology and pathogenesis remain unclear,lacking effective preventive and therapeutic measures.This study aims to explore the association between whole blood copper,zinc,calcium,magnesium and iron levels and NAFLD in overweight and obese children aged 6 to 17 years,providing a scientific basis for the prevention and intervention of early NAFLD in overweight and obese children. Methods:A cross-sectional study design was used to collect relevant data from overweight and obese children who visited the Hunan Children's Hospital from January 2019 to December 2021 through questionnaire surveys.Fasting blood samples were collected from the subjects,and various indicators such as blood glucose,blood lipid,and mineral elements were detected.All children were divided into an overweight group(n=400)and a NAFLD group(n=202).The NAFLD group was divided into 2 subgroups according to the ALT level:A non-alcoholic fatty liver(NAFL)group and a non-alcoholic steatohepatitis(NASH)group.Logistic regression analysis was used to analyze the association between minerals(copper,zinc,calcium,magnesium,and iron)and NAFLD,NAFL and NASH. Results:A total of 602 subjects were included,of whom 73.6%were male,with a median age of 10(9,11)years,and a body mass index(BMI)of 24.9(22.7,27.4)kg/m2.The intergroup comparison results showed that compared with the overweight group,the NAFLD group had higher levels of age,BMI,diastolic blood pressure(DBP),systolic blood pressure(SBP),triglyceride(TG),low density lipoprotein(LDL),alanine transaminase(ALT)and aspartate aminotransferase(AST),and lower level of high density lipoprotein(HDL).The NAFL group had higher levels of age,BMI,DBP,SBP,ALT,and AST,and lower levels of HDL compared with the overweight group.The levels of age,BMI,DBP,SBP,TG,LDL,ALT,and AST of NASH were higher than those in the overweight group,while the level of HDL was lower than that in overweight group(all P<0.017).After adjusting for a variety of confounders,the OR of NAFLD for the highest quantile of iron was 1.79(95%CI 1.07 to 3.00)compared to the lowest quantile,and no significant association was observed between copper,zinc,calcium,and magnesium,and NAFLD.The subgroup analysis of NAFLD showed that the OR for the highest quantile of iron in children with NAFL was 2.21(95%CI 1.26 to 3.88),while no significant association was observed between iron level and NASH.In addition,no significant associations were observed between copper,zinc,calcium,and magnesium levels and NAFL or NASH. Conclusion:High iron level increases the risk of NAFLD(more likely NAFL)in overweight and obese children,while copper,zinc,calcium,magnesium,and other elements are not associated with the risk of NAFLD in overweight and obese children.

Objective:To investigate whether octyl ester derivative of ginsenoside Rh2(Rh2-O)can induce immunogenic cell death of Huh-7 hepatocellular carcinoma cells and possible mechanism.Methods:Huh-7 cells were cultured in vitro,and divided into control group,Rh2-O group,positive control group(mitoxantrone treatment).Viability and apoptosis of cells were detected by CCK-8 and flow cytometry,respectively.Concentrations of high mobility family protein 1(HMGB1)and adenosine triphosphate(ATP)in supernatant were detected by ELISA and chemiluminescence assay,respectively.Membrane eversion of calreticulin(CRT)was detected by immunofluorescence assay.ROS level in cells was detected by fluorescence probe DCFH-DA,and expressions of proteins associated with endoplasmic reticulum stress signaling pathway were detected by Western blot.Results:Rh2-O treatment significantly reduced cell viability,promoted apoptosis,induced secretion of HMGB1,ATP,membrane eversion of CRT,increased accumulation of ROS in cells,and enhanced expressions of endoplasmic reticulum stress-related proteins PERK,eIF2α,p-eIF2α(all P<0.05).After addition of endoplasmic reticulum stress inhibitor 4-phenylbutyric acid(4-PBA),membrane eversion of CRT induced by Rh2-O was significantly inhibited(P<0.05).Conclusion:Rh2-O can induce immunogenic cell death in hepatocellular carcinoma cells,whose mechanism may be associated with activation of endoplasmic reticulum stress and promotion of CRT membrane eversion.

Objective To develop a blood glucose management knowledge questionnaire for perioperative patients with hyperglycemia and test its reliability and validity.Methods The initial questionnaire was formed through literature review,expert consultation,two rounds of Delphi letter consultation,and pre-survey.From August to September 2019,a total of 125 perioperative patients with hyperglycemia who were hospitalized in the surgical ward of the First Affiliated Hospital of Xi'an Jiaotong University were selected as the survey objects by the convenient sampling method.The items of the questionnaire were screened and the reliability and validity were tested.Results A total of 125 questionnaires were distributed and 115 valid questionnaires were returned,with an effective recovery rate of 92.0%.The blood glucose management knowledge questionnaire for perioperative patients with hyperglycemia included five dimensions(17 items in total),including influencing factors and hazards of abnormal blood glucose,key points of preoperative and postoperative nursing observation,perioperative blood glucose control goals,perioperative blood glucose management points,and emergency treatment of perioperative critical conditions.The effective recovery rates for both rounds of inquiry are 100.00%,the expert authority coefficient was 0.880 and the average coefficient of variation was 0.086 and 0.065(P＜0.01).Exploratory factor analysis extracted a total of five common factors,and the cumulative variance contribution rate was 79.895%.The Cronbach's α coefficient of the questionnaire was 0.905,the test-retest reliability was 0.955,and the content validity index was 0.968.Conclusions The blood glucose management knowledge questionnaire for perioperative patients with hyperglycemia is scientific and practical,which can be used as an effective tool to evaluate the blood glucose management knowledge level during perioperative period.

OBJECTIVES: The increasing costs of hospital delivery have increased the economic burden of pregnant women, and the mode of delivery is the main factor affecting the costs of hospital delivery. This study aims to explore the difference in costs between cesarean section and natural delivery, and to provide reference for controlling the increase of hospital delivery costs. METHODS: The data of inpatient delivery in the Hunan Maternal and Child Health Care Hospital from January 2016 to December 2020 were selected to compare the total inpatient costs and average daily costs of cesarean section and natural delivery. The linear trend model was used to analyze the trend change of inpatient delivery costs and the generalized linear model was used to analyze the influential factors for inpatient delivery costs. RESULTS: The average hospitalization costs of cesarean section (10 447.25 yuan) were higher than that of natural delivery (5 567.95 yuan), and the average daily costs of cesarean section (1 902.57 yuan) were higher than those of natural delivery (1 666.40 yuan). There was no significant increase or decrease in trend for cesarean section, while the average annual growth rate of the costs of natural delivery was 11.79%. The main factors affecting the hospitalization costs of cesarean section and natural delivery included age, occupation, medical insurance, route of admission, length of stay, premature delivery and complications (all P<0.05). CONCLUSIONS The total hospitalization costs and average daily costs of cesarean section are higher than those of natural delivery, but the costs of natural delivery show a faster growth trend, and the hospitalization costs of cesarean section and natural delivery should be controlled by targeted measures.

Depression is one of the most common mental disorders, which can be accompanied by cognitive symptoms in addition to core symptoms.With the improvement of the awareness of the disease, people pay more attention to the cognitive symptoms of depression. The cognitive impairment of patients not only appears in the onset of the disease, but also persists during the remission of the disease, which has a negative impact on the patients’ social function. Some cognitive assessment tools such as cognitive tests, event-related potential(ERP) and eye movement tracking technology have been used to assess cognitive impairment in patients with depression, which show that there are multidimensional cognitive impairments. Some therapeutic methods such as exercise therapy, repetitive transcranial magnetic stimulation(rTMS) and drug therapy have shown the potential to improve the cognitive function of patients with depression. This article reviews related researches in recent years to explore the cognitive impairment and therapeutic methods of patients with depression.

Objective To explore the relationship between different obesity indicators and carotid intima-media thickness(CIMT)in patients with type 2 diabetes mellitus(T2DM).Methods A total of 1762 T2DM patients who visited the Endocrinology Department of Changzhou Second People's Hospital Affiliated with Nanjing Medical University and the Integrated Traditional Chinese and Western Medicine Hospital Affiliated with Nanjing University of Traditional Chinese Medicine from January 2019 to February 2022 were enrolled in this study.They were divided into youth group(18～44 years old,n=402),middle aged group(45～59 years old,n=1032),and elderly group(≥60 years old,n=328)according to WHO age classification criteria.The influencing factors for CIMT thickening in T2DM patients were analyzed using binary logistic regression,and the evaluation of the predictive effect of different obesity indicators on CIMT thickening was evaluated by receiver operating characteristic(ROC)curves.Results The subcuta-neous fat area,visceral fat area(VFA),neck circumference(NC),BMI,WC,cardiac metabolic index(CMI),Chinese visceral fat index(CAVI),visceral fat index,triglyceride glucose index,body roundness index,lipid aggregation index,HbA1c,DBP,TC,TG,HDL-C,LDL-C were lower in the middle aged and elderly groups than in youth group(P＜0.05).Binary logistic regression showed that VFA,NC,CMI in young T2DM patients,CAVI in middle aged T2DM patients,and NC in elderly T2DM patients were influ-encing factors for CIMT thickening.ROC curve analysis showed that VFA in young T2DM patients,CAVI in middle aged T2DM patients,and NC in elderly T2DM patients had a better predictive effect on CIMT thickening,with areas under the ROC curve of 0.567,0.574,and 0.573 respectively.Conclusion VFA,CAVI,and NC have a certain predictive effect on CIMT thickening in young,middle aged,and elderly T2DM patients.

To explore the effects and molecular mechanism of icariin on the vascular function of mice with type 1 diabetes induced by alloxan, type 1 diabetic mice model was established by intraperitoneal injection with 200 mg/kg alloxan.After oral administration with icariin (60, 120 mg/kg) daily for 2 weeks, blood glucose, body weight, food intake and water intake were detected.To evaluate the impact of icariin on the function of isolated vascular ring contraction and relaxation, thoracic aortas of mice were removed and the Ach-induced vascular ring relaxation, Phe-induced vascular ring contraction, SNP-induced vascular ring relaxation and KCl-induced vascular ring contraction response were detected.To further confirm the mechanism of icariin to improve vascular function, human umbilical vein endothelial cells (HUVECs) were induced by high glucose (HG) in vitro.Western blot was used to detect the effect of icariin on eNOS, p-eNOS, p38 MAPK and p-p38 MAPK expressions in HG-induced human umbilical vein endothelial cells (HUVECs).The results indicated that icariin significantly ameliorated the weight loss and dampened the increase in water intake of the diabetic mice.Meanwhile, icariin had a certain ameliorative effect on blood glucose and food intake without significant difference.The results of isolated thoracic aortas vascular rings contraction and vasodilation function indicated that icariin significantly improved Phe-induced vascular contraction and Ach‐induced vascular relaxation.Meanwhile, icariin had a certain ameliorative effect on KCl-induced vascular contraction response without significant difference.However, no significant change was observed on endothelium‐independent vascular rings relaxation response induced by SNP after treatment with icariin.Results of Western blot showed that icariin inhibited the expression of p-p38 MAPK and induced expression of p-eNOS in the high glucose-induced HUVECs cell model.Therefore, icariin may attenuate alloxan-induced type 1 diabetic mice vascular diastolic function by inhibiting expression of p-p38 MAPK and inducing expression of p-eNOS.
