Objective: To analyze the impact of maternal metal exposure during early pregnancy on the physical development of offspring at 1 and 3 years of age, so as to provide scientific evidence for reducing the adverse effects of heavy metals on their health. Methods: From 2024 to 2018, a total of 1 588 mother child pairs from the Jiangsu Birth Cohort (JBC) were included in this study. Multiple linear regression models, generalized estimating equations (GEE), and weighted quantile sum (WQS) regression models were used to assess the associations between 24 urinary metal mass concentrations (adjusted for specific gravity, SG) during early pregnancy and offspring growth outcomes, including length/height for age Z score(HAZ), weight for age Z score(WAZ), weight for length/height Z score(WHZ), and head circumference for age Z score(HCAZ) at 1 and 3 years of age. Results: After adjusting for confounders, GEE analysis revealed that each natural log unit increase in maternal urinary concentrations of vanadium, tin, cerium, lead, and uranium during early pregnancy was associated with an average reduction in HCAZ by 14.29%, 4.82%, 2.62 %, 5.04 %, and 8.33%, respectively, at 1 and 3 years of age (FDR- P <0.05). Multiple linear regression analysis revealed that increased urinary vanadium concentration was associated with reduced HAZ at 1 year of age, while increased urinary concentrations of vanadium, chromium, tin, antimony, and uranium were associated with reduced HCAZ at 1 year of age (FDR- P <0.05). In the WQS regression model, each unit increase in the WQS index was associated with a 22.64% reduction in HCAZ at 1 year of age, with tin (22.2%) contributing the highest weight, followed by uranium (16.2%), lead (11.5%), vanadium (10.0%), arsenic (6.5%), and chromium (5.0%). Conclusions Prenatal exposure to specific metals and their mixtures may significantly impact the physical development of offspring at 1 and 3 years of age, particularly head circumference. These findings highlight the need to enhance monitoring of maternal metal exposure during early pregnancy to reduce the potential health risks posed by environmental metal pollution to infants and young children.

Objective: To compare the intervention effects of sitagliptin combined with metformin and insulin aspart combined with metformin among patients with type 2 diabetes mellitus (T2DM), so as to provide the reference for optimizing blood glucose control strategies among patients with T2DM. Methods: T2DM patients admitted to the department of endocrinology of Jinhua Central Hospital from January 2018 to December 2024 were selected as the research objects. According to the propensity score matching, T2DM patients were divided into sitagliptin combined with metformin group and insulin aspart combined with metformin group at a ratio of 1∶1. The basic information, capillary blood glucose, glycosylated hemoglobin blood glucose (HbA1c), total cholesterol (TC), high density lipoprotein cholesterol (HDL-C), triglyceride (TG), body mass index (BMI), systolic blood pressure (SBP) and diastolic blood pressure (DBP) of the two groups were collected by questionnaire survey, physical examination and laboratory test. The generalized estimating equation was used to analyze the changes of various indicators before and after treatment between the two groups of patients, and the intervention effect was compared. Results: There were 69 cases in the sitagliptin combined with metformin group. Among these 42 cases were males, accounting for 60.87%, and 27 cases were females, accounting for 39.13%.Forty-two cases were younger than 60 years, accounting for 60.87%. There were 69 cases in the insulin aspart combined with metformin group. Among these 47 cases were males, accounting for 68.12%, and 22 cases were females, accounting for 31.88%. Forty-five cases were younger than 60 years, accounting for 65.22%. There were no statistically significant differences in gender, age, education level, smoking, drinking, vegetable and fruit intake, and disease duration between the two groups (all P>0.05). After 6 months of treatment, there was an interaction between group and time in capillary blood glucose and HbA1c in the two groups (all P<0.05), and the reduction of capillary blood glucose and HbA1c in the sitagliptin combined with metformin group was greater than that in the insulin aspart combined with metformin group. There were no statistically significant differences between groups and time in TC, HDL-C, TG, BMI, SBP, and DBP, and no interaction effect was found between groups and time (all P>0.05). Conclusion Sitagliptin combined with metformin is more effective than insulin aspart combined with metformin in controlling blood glucose among patients with T2DM.

BACKGROUND: Owing to the high prevalence of antibiotic resistance in Helicobacter pylori ( H. pylori ) in China, bismuth-containing quadruple therapies have been recommended for H. pylori eradication. This study compared the efficacy and safety of quadruple regimens containing vonoprazan vs . esomeprazole for H. pylori eradication in a patient population in China. METHODS: This was a phase 3, multicenter, randomized, double-blind study. Patients with confirmed H. pylori infection were randomized 1:1 to receive quadruple therapy for 14 days: amoxicillin 1000 mg and clarithromycin 500 mg after meals, bismuth potassium citrate 600 mg before meals, plus either vonoprazan 20 mg or esomeprazole 20 mg before meals, all twice daily. The primary outcome was the eradication rate of H. pylori , evaluated using a 13 C urea breath test at 4 weeks after treatment. The non-inferiority margin was at 10%. RESULTS: The study included 510 patients, 506 of whom completed the follow-up assessment. The primary analysis revealed eradication rates of 86.8% (210/242) and 86.7% (208/240) for vonoprazan and esomeprazole therapy, respectively (treatment difference: 0.1%; 95% confidence interval [CI]: -5.95, 6.17; non-inferiority P  = 0.0009). Per-protocol analysis showed eradication rates of 87.4% for vonoprazan and 86.3% for esomeprazole (treatment difference: 1.2%; 95% CI: -5.03, 7.36; non-inferiority P  = 0.0004). Vonoprazan and esomeprazole were well tolerated, with similar safety profiles. CONCLUSION: Vonoprazan was found to be well-tolerated and non-inferior to esomeprazole for eradicating H. pylori in patients from China. TRIAL REGISTRATION ClinicalTrials.gov , NCT04198363.

Objective:To evaluate the efficacy and safety of hypomethylating agents (HMA) in patients with myelodysplastic syndromes (MDS) .Methods:A total of 409 MDS patients from 45 hospitals in Zhejiang province who received at least four consecutive cycles of HMA monotherapy as initial therapy were enrolled to evaluate the efficacy and safety of HMA. Mann-Whitney U or Chi-square tests were used to compare the differences in the clinical data. Logistic regression and Cox regression were used to analyze the factors affecting efficacy and survival. Kaplan-Meier was used for survival analysis. Results:Patients received HMA treatment for a median of 6 cycles (range, 4-25 cycles) . The complete remission (CR) rate was 33.98% and the overall response rate (ORR) was 77.02%. Multivariate analysis revealed that complex karyotype ( P=0.02, OR=0.39, 95% CI 0.18-0.84) was an independent favorable factor for CR rate. TP53 mutation ( P=0.02, OR=0.22, 95% CI 0.06-0.77) was a predictive factor for a higher ORR. The median OS for the HMA-treated patients was 25.67 (95% CI 21.14-30.19) months. HMA response ( P=0.036, HR=0.47, 95% CI 0.23-0.95) was an independent favorable prognostic factor, whereas complex karyotype ( P=0.024, HR=2.14, 95% CI 1.10-4.15) , leukemia transformation ( P<0.001, HR=2.839, 95% CI 1.64-4.92) , and TP53 mutation ( P=0.012, HR=2.19, 95% CI 1.19-4.07) were independent adverse prognostic factors. There was no significant difference in efficacy and survival between the reduced and standard doses of HMA. The CR rate and ORR of MDS patients treated with decitabine and azacitidine were not significantly different. The median OS of patients treated with decitabine was longer compared with that of patients treated with azacitidine (29.53 months vs 20.17 months, P=0.007) . The incidence of bone marrow suppression and pneumonia in the decitabine group was higher compared with that in the azacitidine group. Conclusion:Continuous and regular use of appropriate doses of hypomethylating agents may benefit MDS patients to the greatest extent if it is tolerated.

Objective:To explore the symptom management experience in young and middle-aged patients with home peritoneal dialysis.Methods:Using the descriptive phenomenological research method and purposive sampling method, 13 young and middle-aged peritoneal dialysis patients were selected for semi-structured interviews, and the interview data was analyzed and sorted out to extract themes.Results:A total of four themes were summarized, including difficulties in symptom management (lack of symptom management knowledge, insufficient symptom perception ability), effect of poor symptom management effectiveness (limited daily life behavior, weakened family roles, obstacles in returning to the workplace, withdrawal of social activities and increased economic burden), polarized symptom management coping strategies (positive and negative responses) and multifaceted symptom management needs (longing for new treatment methods, hoping for disease knowledge popularization and craving for social support in various aspects) .Conclusions:There are many obstacles and needs in the process of symptom self-management of young and middle-aged home peritoneal dialysis patients. It is suggested that medical staff should combine the characteristics and psychology of middle-aged and young peritoneal dialysis patients, implement targeted intervention measures, and improve their symptom management ability.

OBJECTIVE To investigate the improvement effects of Jinkui shenqi pills on polycystic ovary syndrome （PCOS） model rats and the mechanism. METHODS Totally 40 rats were given letrozole suspension instragastrically （1 mg/kg， once a day， for consecutive 21 d） to induce PCOS model. Model rats were divided into model group， ethinylestradiol and cyproterone acetate tablets （short for diane-35）+metformin group （diane-35 0.2 mg/kg + metformin 230 mg/kg， as positive control）， Jinkui shenqi pills low-dose， medium-dose and high-dose groups （0.5， 1.0， 2.0 g/kg）， with 10 rats in each group. Other 10 healthy rats were included in normal group. Each group was given the corresponding drugs， once a day， for consecutive 30 d. Twelve hours after the last administration， serum levels of blood glucose， insulin， estrogen （E2）， testosterone （T）， gonadotropin-releasing hormone （GnRH）， follicle-stimulating hormone （FSH） and luteinizing hormone （LH） were measured. The insulin resistance indexes were calculated， and the ovary coefficients of rats were calculated. The pathological changes of ovary were observed. The protein and mRNA expressions of liver kinase B1 （LKB1） and AMP-activated protein kinase （AMPK） in ovary tissue were detected. RESULTS Compared with normal group， the levels of blood glucose， insulin， insulin resistance index， serum levels of T， GnRH and LH and ovarian indexes were significantly increased （P＜0.05）， while serum levels of E2 and FSH as well as protein and mRNA expressions of LKB1 and AMPK in ovary tissue were decreased significantly （P＜0.05）； collagenization of ovarian cortex， increased number of atresia follicles and cystic follicles without cumulus， and follicular cystic lesions could be seen. Compared with model group， most of above indexes of Jinkui shenqi pills groups were reversed significantly （P＜0.05）； the number of follicle at each level was increased and no follicular cystic lesion was found in Jinkui shenqi pills medium-dose and high-dose groups. CONCLUSIONS Jinkui shenqi pills can significantly improve the abnormal level of sex hormones， insulin resistance and 222102310139） ovarian cystic changes， the mechanism of which may be related to up-regulating the activation of LKB1/AMPK signaling pathway.

Objective: To describe the epidemiological characteristics and clinical manifestations of the 2019 coronavirus disease (COVID-19) in pediatric patients, and to provide data support and decision-making basis for the prevention and control of COVID-19. Methods: Cases of children aged 0-17 years reported by provincial health commissions in Anhui, Shandong, Zhejiang and Henan provinces were collected to analyze their spatial, temporal, and demographic distribution. Results: By 24:00 on February 6, 2020, a total of 107 pediatric patients had been reported in the four provinces, accounting for 3.8% (107/2 808) of the total cases reported in the four provinces during the same period. Anhui, Shandong, Zhejiang and Henan provinces had 25, 25, 28 and 29 cases, respectively. Cases ranged in age from 5 days after birth to 17 years, with a median age of 8 years. Boys accounted for 58.9%. Totally 38 cases had a history of sojourn in Wuhan or Hubei, 63 cases had a history of exposure to confirmed cases, and 6 cases with unknown exposure history. A group of 52 family clustering were found in 107 cases. All cases presented mild symptoms, no serious and no death. Conclusion Children were also susceptible to the COVID-19. Before February 2, the index pediatric cases were mainly the first generation cases, and after February 3, these pediatric cases were mainly the secondary-generation cases and those who had close contact with confirmed cases. The monitoring of children with secondgeneration cases and close contact with COVID-19 cases were valued.

We used the epidemic data of COVID-19 published on the official website of the municipal health commission in Anhui province. We mapped the spatiotemporal changes of confirmed cases, fitted the epidemic situation by the population growth curve at different stages and took statistical description and analysis of the epidemic situation in Anhui province. It was found that the cumulative incidence of COVID-19 was 156/100 000 by February 18, 2020 and the trend of COVID-19 epidemic declined after February 7, changing from J curve to S curve. The actual number of new cases began to decrease from February 2 to February 4 due to the time of case report and actual onset delayed by 3 to 5 days.

Objective To systematically explore the efficacy of four intervention regiments including desmopressin, alarm, desmopressin combined with alarm, and desmopressin combined with anticholinergic drugs in the treatment of monosymptomatic nocturnal enuresis in children by network meta-analysis. Methods The databases of PubMed, Cochrance Library, EMBase and Web of Science were systematically searched and retrieved upto August 1, 2017. Included were the randomized controlled trials (RCTs) which had any two or more of four intervention regiments (desmopressin, alarm, desmopressin combined with alarm, and desmopressin combined with anticholinergic drugs) for treatment of monosymptomatic nocturnal enuresis in children. The literature was screened according to the established inclusion and exclusion criteria, and the data extraction and quality evaluation were performed for the final inclusion of RCT. Software R 3.3.2 and STATA 14.0 were used for data analysis. Results Fifteen RCTs were included with a total of 1505 children. Network meta-analysis showed that the complete response rate and success rate of desmopressin combined with anticholinergic drugs were higher than those of desmopressin (complete reaction rate: OR=2.8, 95％ CI :1.5～5.4; success rate: OR=3.5, 95％ CI :1.7～7.5) and alarm (complete response rate: OR=2.7, 95％ CI :1.1～6.6; success rate: OR=3.8, 95％ CI: 1.6～9.0. The success rate of desmopressin combined with alarm was higher than that of alarm (OR=1.9, 95％CI: 1.1～3.4) . The recurrence rate of alarm after treatment was significantly lower than that of desmopressin (OR=0.15, 95％CI: 0.03～0.53) . The ranking results showed that the complete response rate and success rate of desmopressin combined with anticholinergic drugs were the best. The desmopressin combined with alarm can minimize the number of bed-wetting episodes per week and the recurrence rate of alarm was the lowest among the four regiments. Conclusion The effect of desmopressin combined with anticholinergic drugs is significantly better than that of alarm or desmopressin alone. The combination of desmopressin and alarm has a slight advantage or similar effect to that of single alarm or desmopressin treatment. The effect of desmopressin is similar to that of alarm. Alarm treatment has the lowest recurrence rate.
