Objective: To explore the early effects of birth weight at different gestational ages on blood pressure trajectory among primary school students, so as to provide evidence for incorporating gestational age birth weight into individualized early warning and intervention strategies for childhood hypertension. Methods: From May to November 2023, a purposeful sampling method was used to recruit 1 676 students in grade 1-3 from three primary schools in a certain urban district of Chongqing. Follow up assessments were conducted in May 2024(T1), November 2024(T2), and May 2025(T3). General demographic and birth related information were collected via self administered questionnaires, while height, weight and blood pressure were obtained through physical examinations. Linear mixed effects model was used to analyze the associations between birth weight at different gestational ages and blood pressure trajectories. Results: During the T1-T3 period, the systolic blood pressure of boys were 98.5 (93.0, 104.5 ),98.5 (93.5, 105.0), and 97.5 (92.5, 103.5)mmHg, respectively, while the diastolic blood pressure were 60.5 (56.5, 65.0), 61.5 ( 57.0 , 65.5), and 60.0 (56.0, 64.0)mmHg, respectively. For girls, the systolic blood pressure were 95.5 (90.0, 102.0),95.5 (90.5, 101.5), and 96.0 (90.5, 101.5)mmHg, respectively, and the diastolic blood pressure were 60.5 (56.0, 64.5 ),61.5 (57.5, 65.5), and 59.5 (56.0, 63.0)mmHg, respectively. Through Friedman test within both boys and girls, diostolic blood pressure were statistically significant across three measurements( χ 2=48.85，81.54，both P <0.01). The proportion of normal blood pressure increased , and the proportion of prehypertension and hypertension decreased with time( χ 2=39.72，25.62，both P < 0.01 ). Linear mixed effects model analysis revealed that after adjusting for age, sex, household income monthly, parental education, family history of hypertension and maternal pregnancy complications, large for gestational age had significantly higher trajectories of systolic ( β = 1.50) and diastolic( β =0.94) blood pressure compared to appropriate for gestational age(both P <0.01). Conclusion Large for gestational age is associated with elevated blood pressure trajectories during school age, and it may be considered as an early indicator for individualized screening and intervention for childhood hypertension.

ObjectiveTo investigate the status of overlapping hepatitis B virus （HBV） infection in patients with chronic hepatitis C virus （HCV） infection and the serological characteristics of such patients. MethodsA total of 8 637 patients with HCV infection who were hospitalized from January 1， 2010 to December 31， 2020 and had complete data of HBV serological markers were enrolled， and the composition ratio of patients with overlapping HBV serological markers was analyzed among the patients with HCV infection. The patients were divided into groups based on age and year of birth， and serological characteristics were analyzed， and the distribution of HBV-related serological characteristics were analyzed across different HCV genotypes. ResultsThe patients with HCV/HBV overlapping infection accounted for 5.85%， and the patients with previous HBV infection accounted for 48.10%； the patients with protective immunity against HBV accounted for 14.67%， while the patients with a lack of protective immunity against HBV accounted for 31.39%. The patients were divided into groups based on age： in the 0 — 17 years group， the patients with protective immunity against HBV accounted for 61.41% （304 patients）； the 18 — 44 years group was mainly composed of patients with previous HBV infection （698 patients， 37.31%）， the 45 — 59 years group was predominantly composed of patients with previous HBV infection （1 945 patients， 50.38%）， and the ≥60 years group was also predominantly composed of patients with previous HBV infection （1 486 patients， 61.66%）. The patients were divided into groups based on the year of birth： in the pre-1992 group， the patients with previous HBV infection accounted for 51.63% （4 112 patients）； in the 1992 — 2005 group， the patients with protective immunity against HBV accounted for 54.72% （168 patients）； in the post-2005 group， the patients with protective immunity against HBV accounted for 64.38% （235 patients）. In this study， 6 301 patients underwent HCV genotype testing： the patients with genotype 1b accounted for the highest proportion of 51.71% （3 258 patients）， followed by those with genotype 2a （1 769 patients， 28.07%）， genotype 3b （63 patients， 1.00%）， genotype 3a （10 patients， 0.16%）， genotype 4 （21 patients， 0.33%）， and genotype 6a （5 patients， 0.08%）. ConclusionWith the implementation of hepatitis B planned vaccination program in China， there has been a significant reduction in the proportion of patients with previous HBV infection among the patients with HCV/HBV overlapping infection， but there is still a relatively high proportion of patients with a lack of protective immunity against HBV.

OBJECTIVE To evaluate the efficacy and safety of cadonilimab plus chemotherapy in patients with advanced gastric adenocarcinoma or adenocarcinoma of gastroesophageal junction （AEG） with intermediate， low， or no human epidermal growth factor receptor 2 （HER2） expression. METHODS Patients with advanced gastric adenocarcinoma or AEG with intermediate， low， or no HER2 expression who were treated at Liaoning Cancer Hospital between October 1， 2024 and June 30， 2025 were retrospectively included. According to the treatment regimen received， the patients were divided into group A [cadonilimab plus oxaliplatin and capecitabine （XELOX）， n ＝54 ] ， group B （sintilimab plus XELOX， n ＝68）， and group C （tislelizumab plus XELOX， n ＝49）. Short-term efficacy after 4 cycles of treatment， survival outcomes， and adverse events were compared among the three groups. Cox regression and Logistic regression analyses were further performed to evaluate the effects of the treatment regimen and baseline data on survival outcomes and the risk of grade 3-4 treatment related adverse events （TRAEs）. RESULTS No statistically significant differences in objective response rate or disease control rate were observed among the three groups （ P ＞0.05）. The median progression-free survival was 7.56 （5.62， 8.11） months in group A， 7.23 （5.33， 8.23） months in group B， and 7.33 （5.42， 8.19） months in group C， with no statistically significant difference among the three groups （ P ＞0.05）. The median overall survival （mOS） was 11.67 （8.82， 13.88） months in group A， 9.78 （6.82， 12.73） months in group B， and 9.69 （6.78， 12.66） months in group C. The mOS was significantly longer in group A than in group B and group C （ P ＜0.05）， whereas no statistically significant difference was observed between group B and group C （ P ＞0.05）. The correlation analysis indicated that treatment regimen， Eastern Cooperative Oncology Group performance status （ECOG PS）， number of metastatic organs， and peritoneal metastasis may be associated with overall survival （OS）. No significant association was observed between treatment regimen and the risk of grade 3-4 TRAEs. The incidences of grade 1-2 or grade 3-4 TRAEs did not differ significantly among the three groups （ P ＞0.05）. CONCLUSIONS In patients with advanced gastric adenocarcinoma or AEG with intermediate， low， or no HER2 expression， cadonilimab plus XELOX may provide a more significant OS benefit with a safety profile comparable to that of sintilimab or tislelizumab plus XELOX. Further studies with larger sample sizes are required to validate these findings.

Objective To explore the regulatory mechanism of NFE2L2/KEAP1 in alveolar bone repair induced by periodontitis.Methods A rat periodontitis model was established and divided into four groups:Control group(n=6);Periodontitis model group(n=6);Periodontitis+lentivirus empty vector group(n=6);Periodontitis+NFE2L2 overexpression plasmid group(n=6).Histopathological changes in each group were observed using HE staining.TRAP staining was used to detect osteoclast positivity,while ELISA was employed to measure inflammatory cytokine levels in tissues.Immunofluorescence and qPCR were used to detect NFE2L2 expression,and western blot was used to assess the expression of osteogenic proteins ALPL2,RUNX2,and COL1.Primary periodontal ligament cells(hPDLCs)were cultured,and cells were transfected to overexpress NFE2L2 and KEAP1.The cells were divided into six groups:Normal group;Model group;pcDNA-NC group;pcDNA-NFE2L2 group;pc-NFE2L2+pcDNA-NC group;pc-NFE2L2+pcDNA-KEAP1 group.A cellular model was established,and the morphology of primary hPDLCs was observed under a microscope.Cell proliferation was assessed using CCK-8.Osteogenic mineralization was observed using alizarin red staining,and western blot was used to detect osteogenic proteins and autophagy markers.Cell migration was observed using a scratch assay.Results(1)After model induction,redness,swelling of the gums,extensive inflammatory infiltration,and alveolar bone resorption were observed,confirming successful model establishment.Partial tissue recovery occurred after NFE2L2 overexpression via lentivirus.(2)After model induction,osteoclast positivity increased,confirming successful model establishment.Overexpression of NFE2L2 reduced osteoclast positivity(P<0.001).(3)After model induction,levels of IL-1β,IL-10,and TNF-α were significantly higher than in the normal group(P<0.05),confirming successful model establishment.Transfection with NFE2L2 lentivirus reduced inflammatory cytokine levels(P<0.0001).After model induction,osteogenic protein expression decreased compared to the normal group,but overexpression of NFE2L2 increased osteogenic protein expression(P<0.05).(5)LPS treatment significantly reduced cell viability,while NFE2L2 overexpression enhanced it(P<0.0001).(6)LPS treatment reduced calcified nodules,while NFE2L2 overexpression increased them.Addition of pcDNA-KEAP1 reduced mineralized nodules.(7)LPS treatment decreased osteogenic protein expression,while NFE2L2 overexpression increased it.However,addition of pcDNA-KEAP1 reduced osteogenic protein expression(P<0.05).(8)LPS treatment reduced cell migration,whereas NFE2L2 overexpression enhanced it(P<0.0001).(9)Expression of autophagy markers decreased after LPS treatment,but increased after transfection with NFE2L2 plasmid.However,addition of pcDNA-KEAP1 reduced the expression of autophagy markers(P<0.05).Conclusion This study identified the regulatory role of NFE2L2/KEAP1 in periodontitis,providing a scientific basis for the treatment of periodontitis.

Objective: To investigate the characteristics of malignant tumor incidence and mortality in cancer registration areas of Zhejiang Province in 2021. Methods: Based on the 2021 cancer registration data from 22 national cancer registries in Zhejiang Province, the crude incidence, crude mortality, and cumulative rate for 0 to 74 years were calculated. Age standardized was performed using the age composition of the standard population from the Fifth National Population Census in 2000 and Segi's world standard population. The incidence and mortality characteristics of malignant tumor in different genders, urban/rural areas and ages were described. The order of crude incidence and mortality of malignant tumor were analyzed. Results: In 2021, there were 116 639 new malignant tumor cases in Zhejiang Province. The crude, Chinese population standardized, and world population-standardized incidences were 530.93/100 000, 304.83/100 000, and 288.20/100 000, respectively. The cumulative incidence for 0 to 74 years was 31.92%. There were 40 475 death cases. The crude, Chinese population-standardized, and world population-standardized mortalities were 184.24/100 000, 79.40/100 000, and 78.97/100 000, respectively. The cumulative mortality for 0 to 74 years was 8.37%. The Chinese population-standardized incidence for males and females were 286.34/100 000 and 323.45/100 000, respectively, and the Chinese population-standardized mortality were 106.25/100 000 and 54.17/100 000, respectively. The Chinese population-standardized incidence for urban and rural were 316.85/100 000 and 285.11/100 000, respectively, and the Chinese population-standardized mortality were 75.59/100 000 and 85.48/100 000, respectively. The crude incidence and crude mortality of malignant tumor both increased with age, peaking in the groups aged 80-<80 and ≥85 years at 1 845.06/100 000 and 1 656.88/100 000, respectively. The top ten malignant tumors with the highest crude incidence were, in descending order: lung cancer, thyroid cancer, breast cancer, prostate cancer, colorectal cancer, gastric cancer, liver cancer, cervical cancer, lymphoma, and brain tumors. These accounted for 80.34% of all new malignant tumor cases. The top ten malignant tumors with the highest crude mortality were, in descending order: lung cancer, liver cancer, colorectal cancer, gastric cancer, pancreatic cancer, prostate cancer, breast cancer, esophageal cancer, lymphoma, and gallbladder cancer. These accounted for 82.26% of all malignant tumor deaths. Conclusions In 2021, the cancer registration areas of Zhejiang Province were characterized by a relatively high malignant tumor incidence and a comparatively low mortality compared to national data. Males and the elderly emerged as key populations for targeted prevention and control. It is recommended to enhance screening, early diagnosis, and early treatment for lung cancer, thyroid cancer, prostate cancer, breast cancer, and gastric cancer malignancies.

Objective:To analyze the clinicopathological characteristics of atypical teratoid/rhabdoid tumors (AT/RT) and the causes of pathological misdiagnosis, and summarize diagnostic strategies.Methods:A case series study was conducted.Specifically, the data of 5 misdiagnosed(misdiagnosed group) and 8 confirmed AT/RT cases(confirmed group) in the Department of Pathology of Xi′an Children′s Hospital from January 2010 to December 2018 were retrospectively analyzed.Hematoxylin-eosin and immunohistochemical staining were performed to analyze clinical features, morphology, and immune phenotypes.Rates were compared between the misdiagnosed and confirmed groups by a Fisher′s exact test.Means were compared using an independent sample t-test.Medians were compared by a Mann-Whitney U test. Results:(1)There were 4 males and 1 female in the misdiagnosed group, with a median age of 24 months.In this group, 4/5 tumors were located in the posterior cranial fossa, and 1/5 tumors were located in the spinal cord.Morphologically, rhabdoid cells were detected in 3/5 cases, and the other 2/5 cases consisted of small embryonal cells.Immunohistochemically, INI1 and BRG1 expressions were absent in 4/5 and 1/5 cases, respectively.All of them showed multiple immunephenotypes.There were 7 males and 1 female in the confirmed group, with a median age of 22 months.In the confirmed group, 4/8 tumors were located in the supratentorial region and 4/8 tumors were located in the infratentorial region.Rhabdoid cells, deficient INI1 expression and multiple immunephenotypes were observed in all 8 cases.(2)The percentage of rhabdoid cells in the misdiagnosed group was significantly lower[0.45(0, 0.46)] than that in the confirmed group[0.55(0.40, 0.85)]( Z=-2.064, P=0.039). Conclusions:The causes of misdiagnosis of AT/RT are variable sites of occurrence, diverse histomorphology, multiple phenotypes in immunohistochemistry and rare BRG1 deficiency.For high-grade rhabdoid, epithelioid, and/or embryonic small cell tumors, AT/RT should be differentiated and immunohistochemistry protocols should include INI1 and BRG1.

The pharmaceutical industry faces challenges in quality digitization for complex multi-stage processes, especially in small-sample systems. Here, an intelligent quality prediction and diagnostic (IQPD) framework was developed and applied to Tong Ren Tang's Niuhuang Qingxin Pills, utilizing four years of data collected from four production units, covering the entire process from raw materials to finished products. In this framework, a novel path-enhanced double ensemble quality prediction model (PeDGAT) is proposed, which combines a graph attention network and path information to encode inter-unit long-range and sequential dependencies. Additionally, the double ensemble strategy enhances model stability in small samples. Compared to global traditional models, PeDGAT achieves state-of-the-art results, with an average improvement of 13.18% and 87.67% in prediction accuracy and stability on three indicators. Additionally, a more in-depth diagnostic model leveraging grey correlation analysis and expert knowledge reduces reliance on large samples, offering a panoramic view of attribute relationships across units and improving process transparency. Finally, the IQPD framework integrates into a Human-Cyber-Physical system, enabling faster decision-making and real-time quality adjustments for Tong Ren Tang's Niuhuang Qingxin Pills, a product with annual sales exceeding 100 million CNY. This facilitates the transition from experience-driven to data-driven manufacturing.

Objective:To compare the clinical characteristics of monogenic and non-monogenic early-onset inflammatory bowel disease (EO-IBD) in children and to explore the necessity of genetic analysis in EO-IBD research.Methods:A retrospective analysis of clinical data was conducted on 73 children diagnosed with EO-IBD at the Children's Hospital affiliated with Capital Institute of Pediatrics between January 2017 and December 2023. Genetic analysis was performed utilizing next-generation sequencing technology, with patients stratified into monogenic and non-monogenic groups based on the presence or absence of pathogenic mutations. Subsequently, a comparative analysis of clinical characteristics was conducted between these two cohorts of EO-IBD patients.Results:Among the 73 EO-IBD cases, 27 (37%) were diagnosed as monogenic IBD, and 46 (63%) as non-monogenic IBD. Compared to the non-monogenic group, the monogenic group had an earlier age of onset [1 (0.2, 3.0) months vs. 15 (4.1, 51.3) months, P < 0.001], with a higher incidence within the first month of life (70.4% vs. 13.0%, P < 0.001). Monogenic IBD cases were more likely to present with Crohn's disease (CD) phenotypes (88.9% vs. 52.2%, P = 0.003) and colonic involvement (L2) (91.7% vs. 62.5%, P < 0.001), but were less likely to present with non-penetrating, non-stricturing (B1) disease (87.5% vs. 95.8%, P = 0.019). Children in the monogenic group were more prone to severe malnutrition (74.1% vs. 21.3%, P < 0.001), perianal abscesses (40.7% vs. 8.7%, P < 0.001), perianal tags (22.2% vs. 0%, P = 0.004), fever (74.1% vs. 23.9%, P < 0.001), oral ulcers (44.4% vs. 6.5%, P < 0.001), and skin lesions (33.3% vs. 2.2%, P < 0.001). Regarding treatment, the monogenic group had higher usage of thalidomide (88.9% vs. 54.3%, P = 0.002) and hematopoietic stem cell transplantation (HSCT) (37.0% vs. 0, P < 0.001) and a higher mortality rate (22.2% vs. 2.2%, P = 0.017) . Conclusions:For children with IBD presenting at an early age, especially within the first month of life, and showing symptoms like fever, oral ulcers, skin lesions, severe malnutrition, and perianal disease, monogenic IBD should be considered. Genetic testing results can aid in guiding treatment decisions.

BackgroundModified electroconvulsive therapy （MECT） is a common front-line strategy widely used in psychiatric practice， and the optimal first stimulus dosage in MECT is usually estimated clinically based on the factors influencing the patient's initial seizure threshold （IST）. However， previous studies on the influencing factors of IST have mostly suffered from limitations such as small sample sizes and single-dimensional research perspectives. ObjectiveTo explore the factors influencing IST in MECT for patients with mental disorders， so as to provide references for stimulus dosing strategies in MECT for the patients. MethodsA retrospective study was used to include 1 446 inpatients fulfilling the diagnostic criteria for any specific mental disorder listed in the ICD-10 and receiving MECT at Shandong Daizhuang Hospital from January 1， 2021 to August 1， 2023. Their general and clinical data were collected， including IST， psychiatric diagnostic categories， gender， ethnicity， age， body weight， body mass index （BMI）， course of disease， family history of psychiatric disorders， first episode status， use of antiepileptic drugs the day before treatment， use of benzodiazepines the day before treatment， and previous MECT treatment history. Pearson correlation analysis was utilized to test the correlation of IST with age， height， body weight， BMI， and course of disease， and stepwise multivariate linear regression analysis was performed to identify the factors affecting IST. ResultsIST yielded statistical difference among patients in terms of gender， first episode status， use of antiepileptic drugs the day before treatment， and use of benzodiazepines the day before treatment （t=2.256， -3.059， -2.136， -3.006， P<0.05 or 0.01）. IST in patients of different ages and psychiatric diagnostic categories also demonstrated statistical difference （F=913.120， 6.212， P<0.01）. Within young population， IST varied significantly based on the psychiatric diagnostic categories （F=2.986， P<0.05）. Correlation analysis indicated that IST was positively correlated with age， body weight， BMI and course of disease （r=0.886， 0.055， 0.184， 0.456， P<0.05 or 0.01）， and negatively correlated with height （r=-0.183， P<0.01）. Stepwise multivariate linear regression analysis revealed that age， gender， and body weight were influencing factors of IST （β=0.888， -0.049， -0.035， P<0.01）. ConclusionsAge， gender and body weight may be factors influencing IST in MECT for patients with mental disorders. ［Funded by Key R&D Plan Projects of Jining City in 2024 (number, 2024YXNS202）］
