Objective:To investigate the clinical characteristics of omphalocele, and to assess the risk factors associated with adverse outcomes.Methods:A retrospective cohort study was conducted. Clinical data of 224 patients diagnosed with omphalocele, who were hospitalized at Children′s Hospital, Zhejiang University School of Medicine from January 2013 to December 2022, were collected. Based on their discharge outcomes, the patients were classified into 2 groups: favorable outcomes and unfavorable outcomes. Chi-square test or continuity correction χ2 test or Fisher exact probability method, and Mann-Whitney U test were used for intergroup comparisons. Logistic regression analysis was performed to identify risk factors associated with adverse outcomes in omphalocele. Results:Among the 224 patients with omphalocele, 126 were male. A total of 208 patients (92.9%) had favorable outcomes, while 16 patients (7.1%) had unfavorable outcomes. In the unfavorable outcomes group, 14 patients had giant omphaloceles, while 100 patients had giant omphaloceles in the favorable outcomes group. The rates of herniation of more than two intra-abdominal organs in the hernial sac, congenital heart defects, patent ductus arteriosus, pulmonary hypertension, sepsis and infection of the hernial sac, were all higher in the unfavorable outcomes group compared to the favorable outcomes group (all P<0.05). Patients with unfavorable outcomes had longer mechanical ventilation time, duration of oxygen use, duration of parenteral nutrition, hospital stays, and higher rates of parenteral nutrition-associated cholestasis compared to those with favorable outcomes (all P<0.01). Multivariate Logistic regression analysis indicated that pulmonary hypertension ( OR=9.39, 95% CI 1.20-73.32), sepsis ( OR=8.59, 95% CI 1.32-55.86), and congenital heart defects ( OR=6.55, 95% CI 1.11-38.73) were all independent risk factors for adverse outcomes in omphalocele (all P<0.05). Conclusions:Infants with omphalocele are prone to complications such as cardiovascular malformations, infections, and pulmonary hypertension. Adverse outcomes in omphalocele are associated with pulmonary hypertension, sepsis, and congenital heart defects.

Objective To explore the relationship between education level and the risk of all-cause mortality in the middle-aged and elderly (≥45 years old) population in China. Methods Using data from five surveys from 2011-2020, years of education, age, gender, marital status, type of household, alcohol consumption status, smoking status, physical activity, limited ability to perform activities of daily living (ADLs), chronic disease status, and body mass index were collected. According to the survival status，the study participants were divided into a survival group (n=8625) and an all-cause mortality group (n=1735). Cox proportional risk regression model was used to analyze the relationship between years of education and the risk of all-cause mortality in middle-aged and elderly people with stratified analysis. Results The survey was conducted on 10360 research subjects, including 4 983 males and 5 377 females, with an age M(Q_R) of 59(8) years old. A total of 88 187 person years (average 8.512 person years) were followed up, and a total of 1735 deaths were reported over 9 years. The all-cause mortality rate was 19.674 ‰, with an education period M(Q_R) of 5(8) years and a survival time M(Q_R) of 9 (0) years. After adjusting for confounding factors, for every 1 year increase in education, the risk of all-cause mortality decreased by 2.60% [HR=0.974, 95% CI (0.960-0.988)]. The stratified analysis results showed that in the population aged 45-59, for every 1 year increase in education, the risk of all-cause mortality decreased by 1.00% [HR=0.990, 95% CI (0.959,1.021)]; In the population aged 60-74 and over 75, for every 1 year increase in education, the risk of all-cause mortality decreased by 2.70% [HR=0.973, 95% CI (0.948, 0.999)] and 3.50% [HR=0.965, 95% CI (0.929, 1.003)], respectively. Conclusion Improving the education level of middle-aged and elderly people (≥ 45 years old) in China can reduce the risk of all-cause mortality, and elderly education should be vigorously promoted.

ObjectiveTo investigate the seroprevalence of Japanese encephalitis virus (JEV) IgG antibodies among the healthy individuals in Huzhou City, Zhejiang Province, so as to provide a scientific basis for the development of prevention and control strategies for Japanese B encephalitis (JE). MethodsA cross-sectional study was conducted from 2023 to 2024. Serum samples were collected from healthy individuals across 12 age groups (<8 months, 8 months‒<2 years, 2‒<4 years, 4‒<6 years, 6‒<8 years, 8‒<10 years, 10‒<15 years, 15‒<20 years, 20‒<30 years, 30‒<40 years, 40‒<50 years, 50‒ years) and tested for JEV IgG antibody to determine positivity rates. ResultsThe overall JEV IgG antibody seroprevalence rate was 57.75 % among the healthy individuals in Huzhou City. The positivity rates for the age groups of <8 months, 8 months‒<2 years, 2‒<4 years, 4‒<6 years, 6‒<8 years, 8‒<10 years, 10‒<15 years, 15‒<20 years, 20‒<30 years, 30‒<40 years, 40‒<50 years, and 50‒ years were 10.14%, 23.76%, 77.31%, 66.88%, 73.87%, 58.33%, 41.67%, 55.06%, 47.00%, 61.00%, 62.00%, and 92.00%, respectively, with a statistically significant difference observed in different age groups (χ²=243.996, P<0.001). Seroprevalence rates also differed significantly between males and females (χ²=9.999, P=0.002). Among subjects vaccinated with 0,1 or 2 doses of live attenuated Japanese encephalitis virus vaccine (JEV-L), the IgG antibody seroprevalence rate was 4.76%, 27.27% and 72.33%, respectively (χ²=108.568, P<0.001). Within the 2 doses group, the IgG antibody seroprevalence rate at <1 year, 1 year, 2 years and 3‒5 years after immunization were 80.85%, 77.36%, 66.67% and 65.45%, respectively, indicating a declining trend with time increased since vaccination (Z=-2.024, P=0.043). ConclusionAdults aged 50‒ years maintain high antibody levels, whereas levels are lower among the age groups of <2 years and 8‒<30 years and wane with time since vaccination in Huzhou City. It is recommended to maintain the routine JE vaccination schedule while exploring booster vaccination strategies for the age groups of 8‒<30 years, in order to enhance population immunity against JEV.

OBJECTIVE To investigate the reference range of steady-state trough concentrations in depression patients taking paroxetine. METHODS Therapeutic drug monitoring data of 890 depression inpatients treated with paroxetine in our hospital from January 1， 2023 to December 31， 2024 were retrospectively collected. Univariate analysis and multiple linear regression analysis were employed to explore the influencing factors of the steady-state trough concentration of paroxetine， as well as the correlation between concentration and efficacy and adverse reactions. The reference range of steady-state trough concentration was obtained by receiver operating characteristic（ROC） curve method. RESULTS Patients with a greater degree of improvement in therapeutic efficacy exhibited higher steady-state trough concentrations of paroxetine （P＜0.000 1）. The steady-state trough concentrations of paroxetine and the ratio of paroxetine steady-state trough concentration to dose （C/D ratio） were significantly lower in male patients and those weighing 60-80 kg compared to female patients and those weighing＜60 kg， respectively （P＜0.05 or P＜0.000 1）. The steady-state trough concentration， C/D ratio， dosage， and concomitant medication all showed a positive correlation with therapeutic efficacy （P＜0.05 or P＜0.000 1）. Both the steady-state trough concentration and C/D ratio were correlated with liver function impairment， and the C/D ratio was also correlated with urinary retention （P＜0.05 or P＜0.000 1）. The critical threshold for the effective concentration of paroxetine was 56.31 ng/mL in the overall population， 56.42 ng/mL in males， 44.91 ng/mL in females， and 198.90 ng/mL in patients experiencing adverse reactions. CONCLUSIONS The reference range for the steady-state trough concentration of paroxetine in the overall population is 56.31-198.90 ng/mL； for male patients， it is 56.42-198.90 ng/mL， and for female patients， it is 44.91-198.90 ng/mL. Dosage of paroxetine should be reduced as appropriate for female patients and patients with low body weight or abnormal liver function.

OBJECTIVE To resolve account discrepancies caused by drug price adjustment in medical institution pharmacy management and reduce the time required for price adjustment. METHODS The problems existing in the drug price adjustment models of domestic medical institutions were investigated， and a drug price adjustment system was developed based on price- invoice synchronization mechanism. The system optimized the drug price adjustment process through batch number matching and real-time monitoring functionalities. The account consistency rate and price adjustment time were evaluated before and after system implementation. RESULTS A drug price adjustment system was successfully developed， featuring an innovative “synchronized entry and exit” mode， batch number matching， real-time monitoring， intelligent automation， and electronic traceability. After implementation， the account consistency rate for Western medicines increased from 86.89% （86.66%， 89.63%） to 100% （100%， 100%） （P＝0.005）， while Chinese patent medicines and herbal medicines maintained a 100% （100%， 100%） account consistency rate. Concurrently， the drug price adjustment time significantly decreased from 6.00 （5.00， 7.00）d to 2.50 （1.50， 3.00） d （P＜ 0.001）. CONCLUSIONS The developed system significantly improves account consistency， shortens price adjustment time， and demonstrates notable innovation and practical utility.

Objective: To investigate the epidemiological characteristics of epidemic encephalitis B in Huzhou City, Zhejiang Province from 2007 to 2023, so as to provide the evidence for formulating prevention and control measures for epidemic encephalitis B. Methods: Epidemic encephalitis B case data in Huzhou City from 2007 to 2023 were collected through the National Notifiable Disease Reporting System of the Chinese Disease Prevention and Control Information System. The temporal, regional and population distribution characteristics of laboratory-confirmed epidemic encephalitis B cases were analyzed using the descriptively epidemiological method. Results: A total of 49 laboratory-confirmed epidemic encephalitis B cases were reported in Huzhou City from 2007 to 2023, and the average annual incidence was 0.10/105, showing a significant downward trend (P<0.05). The epidemic encephalitis B cases were concentrated from July to August, and July was the peak month, with 40 cases accounting for 81.63%. There was a statistically significant difference in the average annual incidences of epidemic encephalitis B among counties (districts) (P<0.05). Nanxun District had the highest reported incidence, with an average annual incidence of 0.23/105. There were 30 male cases and 19 female cases, with a male-to-female ratio of 1.58∶1. The youngest case was 5 months old, and the oldest was 49 years old. The children under 15 years were in the majority, with 42 cases accounting for 85.71%. Most of the cases were scattered children, with 25 cases accounting for 51.02%. There were 22 cases with no vaccination history and 21 cases with an unknown vaccination history, accounting for 44.90% and 42.86% respectively. All cases presented with fever. Other main clinical symptoms included listlessness, drowsiness, vomiting and headache, with 47, 40, 33 and 29 cases respectively, accounting for 95.92%, 81.63%, 67.35% and 59.18%, respectively. Conclusions The incidence of epidemic encephalitis B in Huzhou City remained at a relatively low level from 2007 to 2023, with Nanxun District being the high-risk area and July being the peak month for disease incidence. Fever and listlessness were the predominant clinical manifestations. Strengthening vaccination for children under 15 years should be prioritized.

We have isolated an intestinal probiotic strain, Pediococcus acidilactici HRQ-1. To improve its gastrointestinal fluid tolerance, transportation and storage stability, and slow-release properties, we employed the extrusion method to prepare the microcapsules with P. acidilactici HRQ-1 as the core material and sodium alginate and chitosan as the wall material. The optimal conditions for preparing the microcapsules were determined by single factor and orthogonal tests, and the optimal ratio was determined by taking the embedding rate, survival rate, storage stability, gastrointestinal fluid tolerance, and release rate as the evaluation indexes. The results showed that under the optimal embedding conditions, the embedding rate reached (89.60±0.02)%. Under the optimal formula of freeze-drying protective agent, the freeze-drying survival rate reached (76.42±0.13)%, and the average size of the microcapsules produced was (1.16±0.03) mm. The continuous gastrointestinal fluid simulation experiments confirmed that the microcapsules ensured the viable bacterial count and can slowly release bacteria in the intestinal fluid. The curve of the viable bacterial count during storage at 4 ℃ and room temperature indicated that the prepared microcapsules achieved strains' live number protection. The formula and preparation process of P. acidilactici microcapsules may provide a technological reserve for the preparation of more live bacterial drugs in the future.

Objective:To analyze the clinical and genetic features of a child with Primary ciliary dyskinesia (PCD) due to compound heterozygous variants of the CCDC39 gene and a 22q11.21 deletion, and to explore the potential role of the two types of variants in the formation of complex phenotypes. Methods:A child presented at the Shanxi Children′s Hospital in March 2025. due to multiple congenital anomalies was selected as the study subject. Peripheral blood samples were taken from the child and her parents and subjected to whole-exome sequencing (WES). Candidate variants were verified by Sanger sequencing. Effect of splicing variant was predicted using SpliceAI, and pathogenicity was assessed based on the ACMG guidelines. Copy number variation (CNV) analysis was also performed. This study has been approved by the Medical Ethics Committee of the Hospital (Ethics No.: IRB-WZ-2025-019).Results:The patient has exhibited multiple features including severe pneumonia, bronchiectasis, localized pulmonary emphysema, scoliosis, tetralogy of Fallot, and atrial septal defect. Genetic testing revealed that she has harbored compound heterozygous variants of the CCDC39 gene, namely c. 1167+ 1G>A and c. 1009A>T, which were inherited from her father and mother, respectively, with the latter being a novel likely pathogenic variant. In addition, a heterozygous deletion of approximately 708 kb at 22q11.21 was detected. Conclusion:The coexistence of CCDC39 gene variants and a 22q11.21 deletion may underlay the development of complex clinical phenotypes in this child.

This consensus was developed by the Orthodontic Society of the Chinese Stomatological Association to provide a systematic, scientific, and practical guideline for informed consent in orthodontic care. Orthodontic treatment is typically lengthy, highly individualized, and involves multiple factors such as growth and development, occlusal function, and facial esthetics. Rapid technological advances and diverse risk profiles make the traditional reliance on orthodontist experience or institutional templates insufficient to ensure patients′ full understanding and autonomous decision-making. To address this, the expert panel conducted extensive reviews of domestic and international guidelines, analyzed representative dispute cases, and performed multicenter patient-clinician surveys. Using a multi-round Delphi method, the group established a standardized informed consent framework covering the initial consultation, treatment, and retention phases. The consensus emphasizes that informed consent is not only a fundamental legal and ethical requirement but also a key step in building trust, improving patient compliance, and enhancing treatment satisfaction. Orthodontists should clearly and comprehensively explain treatment plans, potential risks, uncertainties, and associated costs, while respecting the autonomy of patients or guardians, and maintain continuous communication and dynamic evaluation throughout the treatment process. The release of this consensus provides unified and authoritative guidance for clinical orthodontics, helping to standardize informed consent, enhance its transparency, safeguard patient rights, reduce medical risks, and promote high-quality, sustainable development of orthodontic practice.

Objective To investigate the protective effect of Yiqi Yangyin Huazhuo Tongluo Formula(YYHT)against high glucose-induced injury in mouse renal podocytes(MPC5 cells)and the possible mechanism.Methods Adult Wistar rats were treated with 19,38,and 76 g/kg YYHT or saline via gavage for 7 days to prepare YYHT-medicated or blank sera for treatment of MPC5 cells cultured in high glucose(30 mmol/L)prior to transfection with a miR-21a-5p inhibitor or a miR-21a-5p mimic.The changes in miR-21a-5p expressions and the mRNA levels of FoxO1,PINK1,and Parkin in the treated cells were detected with qRT-PCR,and the protein levels of nephrin,podocin,FoxO1,PINK1,and Parkin were detected with Western blotting.Autophagic activity in the cells were evaluated with MDC staining.The effect of miR-21a-5p mimic on FoxO1 transcription and the binding of miR-21a-5p to FoxO1 were examined with luciferase reporter gene assay and radioimmunoprecipitation assay.Results MPC5 cells exposed to high glucose showed significantly increased miR-21a-5p expression,lowered expressions of FoxO1,PINK1,and Parkin1 mRNAs,and reduced levels of FoxO1,PINK1,parkin,nephrin,and podocin proteins and autophagic activity.Treatment of the exposed cells with YYHT-medicated sera and miR-21a-5p inhibitor both significantly enhanced the protein expressions of nephrin and podocin,inhibited the expression of miR-21a-5p,increased the mRNA and protein expressions of FoxO1,PINK1 and Parkin,and upregulated autophagic activity of the cells.Transfection with miR-21a-5p mimic effectively inhibited the transcription of FoxO1 and promoted the binding of miR-21a-5p to FoxO1 in MPC5 cells,and these effects were obviously attenuated by treatment with YYHT-medicated sera.Conclusion YYHT-medicated sera alleviate high glucose-induced injury in MPC5 cells by regulating miR-21a-5p/FoxO1/PINK1-mediated mitochondrial autophagy.
