Background Attention-deficit/hyperactivity disorder (ADHD) is one of the most common neurodevelopmental disorders in children and adolescents. Current research suggests that environmental factors, such as per- and polyfluoroalkyl substances (PFAS), may be associated with an increased risk of ADHD in offspring. However, most epidemiological evidence originates from non-Chinese populations, with limited research investigating the association between prenatal PFAS and ADHD-like symptoms in Chinese school-aged children. Objective To examine the association between prenatal PFAS exposure and ADHD-like symptoms in 7-year-old children. Methods Based on the Shanghai Birth Cohort, this study included 488 mother-child pairs. PFAS were measured in maternal serum during the second trimester using ultra-performance liquid chromatography-tandem mass spectrometry. The analysis focused on eight specific compounds from three PFAS categories [perfluorooctanoic acid (PFOA), perfluorooctanesulfonic acid (PFOS), and perfluorohexanesulfonic acid (PFHxS)]. The hyperactivity subscale of the Strengths and Difficulties Questionnaire (SDQ) was used to assess ADHD-like symptoms in children at age 7. Basic demographic information was collected via questionnaires and medical records. Negative binomial regression models were used to evaluate the relationship between individual exposures to the three typical PFAS categories (PFOA, PFOS, and PFHxS) and children's ADHD-like symptoms, while the bayesian kernel machine regression (BKMR) mixture model was employed to assess the overall effect of PFAS mixture exposure on ADHD-like symptoms. Results The detection rates of the eight target PFAS in maternal second-trimester serum were all above 85%, with PFOA exhibiting the highest median concentration (10.21 ng·mL⁻¹). Overall, 14.75% of the children exhibited ADHD-like symptoms. Results from the negative binomial regression models showed that second-trimester exposures to PFOA (IRR=1.15, 95%CI: 1.05, 1.26), n-PFOS (IRR=1.08, 95%CI: 1.01, 1.15), 6m-PFOS (IRR=1.13, 95%CI: 1.05, 1.21), and 1m-PFOS (IRR=1.11, 95%CI: 1.03, 1.18) were associated with an increased risk of ADHD-like symptoms in 7-year-old children. Stratified analyses suggested potentially statistically significant associations in girls [e.g., for PFOA, boys vs. girls: 1.09 (0.96, 1.23) vs. 1.25 (1.09, 1.44), P-int=0.31]. The BKMR mixture model indicated that the risk of ADHD-like symptoms trended upward with increasing PFAS mixture concentrations, although this association was statistically significant only among girls (P < 0.05). Conclusion Prenatal PFAS exposure may be associated with an increased risk of ADHD-like symptoms in 7-year-old children, and this adverse association appears to be more prominent in girls.

Objective: To identify the latent profile characteristics and associated factors of family intergenerational transmission of proactive health behaviors in overweight and obesity junior high school students, so as to provide a reference for promoting active health in adolescents. Methods: From October to December 2024, a stratified cluster random sampling method was employed to select 4 932 junior high school students with overweight and obesity from 18 junior high schools of three cities representing the eastern (Yantai), central (Zibo), and western (Zaozhuang) regions of Shandong Province. Latent profile analysis was used to explore the heterogeneity of family intergenerational transmission among those students. Univariate analysis and multiple Logistic regression analysis were conducted to identify factors associated with different profiles and to examine the influence of profile membership on junior high school students proactive health levels. Results: The intergenerational transmission of health behaviors in junior high school students could be classified into 3 latent profiles:the moderate modeling dysfunctional group (5.88%, n =290), the low modeling advantage deficient group (41.79%, n =2 061), and the high modeling functional harmonious group ( 52.33 % n =2 581). Univariate analysis showed that gender, urban/rural area, region location, paternal/maternal education level, family economic status, and only child status were significantly associated with the classification of latent profiles of intergenerational transmission in families of overweight and obesity junior high school students ( χ 2=7.63-165.22, all P <0.05). Multiple Logistic regression analysis revealed that, using the moderate modeling dysfunctional group as the reference, male students ( OR =0.71) and those residing in coastal cities ( OR =0.74) were less likely to belong to the low modeling advantage deficient group (both P <0.05); students with moderate family economic status were more likely to belong to the low modeling advantage deficient group ( OR =1.72， P <0.05). Conversely, students living in urban areas ( OR =1.43), those with fathers ( OR =2.53) or mothers ( OR =2.48) having a college degree or above, and those with moderate ( OR =3.89) or good ( OR =2.42) family economic status were more likely to be classified into the high modeling functional harmonious group (all P < 0.05 ). Using the low modeling advantage deficient group as the reference, residing in coastal cities ( OR =1.26), living in urban residence ( OR =1.14), having parents (father or mother) with a college education or above ( OR =1.91, 2.33), moderate or good family economic status ( OR = 2.27 , 3.17), and being an only child ( OR =1.19) were associated with a higher probability of belonging to the high modeling functional harmonious group (all P < 0.05 ). There was a statistically significant difference in active health behaviors among students across different latent profiles of family intergenerational transmission ( F =494.79, P <0.01). Conclusions The heterogeneity of family intergenerational transmission is associated the level of proactive health behaviors among junior high school students. Therefore, precision interventions should be implemented based on different categories of family intergenerational transmission, so as to strengthen the efficacy of intergenerational transmission of health behaviors and promote proactive health among junior high school students.

BACKGROUND:Coptis chinensis can clear heat,dry dampness,relieve fire,and detoxify.Coptis chinensis and its components have a significant protective effect on cerebral ischemia.The action mechanism of anti-cerebral ischemia of Coptidis Rhizoma Alkaloids was explored based on network pharmacology and transcriptome sequencing. OBJECTIVE:Based on the study of the protective effects of Coptidis Rhizoma Alkaloids on cerebral ischemia of rats,the action mechanism of Coptidis Rhizoma Alkaloids intervention in cerebral ischemia was investigated by using network pharmacology and transcriptome sequencing technology. METHODS:The SD rats were randomly divided into sham operation group,ischemia/reperfusion group,positive drug group,and Coptidis Rhizoma Alkaloids group.The ischemia/reperfusion model of middle cerebral artery occlusion was prepared by modified thread method in the latter three groups.No thread was inserted and the other operations were the same in the sham operation group.TTC staining,Longa 5 neurological deficient score,hematoxylin and eosin staining,and Nissl staining were used to evaluate the protective effect of Coptidis Rhizoma Alkaloids on ischemia/reperfusion model rats.Transcriptome sequencing was performed on the brain tissues of rats in sham operation group,ischemia/reperfusion group,and Coptidis Rhizoma Alkaloids group.Differentially expressed genes,gene Ontology analysis,Kyoto encyclopedia of genes and genomes analysis,and Correlation Analysis of Transcriptomics and Network Pharmacology were used to elucidate the effect of Coptidis Rhizoma Alkaloids on cerebral ischemia.Finally,ELISA and immunofluorescence staining were used to verify the key targets of Coptidis Rhizoma Alkaloids in the intervention of cerebral ischemia. RESULTS AND CONCLUSION:(1)Coptidis Rhizoma Alkaloids treatment decreased the Longa 5 neurological deficit scores and cerebral infarction area of ischemia/reperfusion model rats,increased the number of neurons and Nissl bodies.(2)Differentially expressed gene after Coptidis Rhizoma Alkaloids treatment analyzed by functional enrichment analysis of gene ontology includes biological processes such as inflammatory reaction and positive regulation of mitogen-activated protein kinase cascade.The enrichment analysis of Kyoto gene and genome encyclopedia analysis pathway mainly involves interleukin-17 signaling pathway,neuroactive ligand-receptor interaction,cyclic adenosine-3′,5′-mconophosphate signaling pathway and so on.(3)Analysis of transcriptomics showed that the main genes regulated by Coptidis Rhizoma Alkaloids were prostaglandin endoperoxide synthase 2,brain derived neurotrophic factor,and transient receptor potential A1.(4)Network pharmacology analysis revealed that nine components in Coptidis Rhizoma Alkaloids may exert their effects by associating with 87 targets related to prostaglandin endoperoxide synthase 2,brain derived neurotrophic factor,and transient receptor potential A1.(5)ELISA and immunofluorescence staining results further confirmed that Coptidis Rhizoma Alkaloids regulated the expression of prostaglandin endoperoxide synthase 2,brain derived neurotrophic factor,and transient receptor potential A1.(6)It is concluded that Coptidis Rhizoma Alkaloids treatment can significantly improve the injury in ischemia/reperfusion model rats,possibly by regulating prostaglandin endoperoxide synthase 2,brain derived neurotrophic factor,and transient receptor potential A1.

Objective:To investigate the risk factors of hypoparathyroidism (HPT) and hypocalcemia in patients undergoing total thyroidectomy (TT), and to explore the changes of parathyroid hormone and blood calcium after TT.Methods:The clinical data of 101 patients undergoing TT from November 2018 to September 2022 in the First Hospital of Hebei Medical University were retrospectively analyzed. The basic clinical data were recorded. The blood calcium and parathyroid hormone levels were measured before surgery and 1 d, 1 week after surgery. The occurrence of postoperative hypocalcemia was recorded. According to postoperative parathyroid hormone level, the patients were divided into control group (normal parathyroid function) and HPT group (reduced parathyroid hormone level). The patients with postoperative hypocalcemia symptoms were classified as the hypocalcemia symptoms group, and the patients without postoperative hypocalcemia symptoms were classified as the non-hypocalcemia symptoms group. Multivariate Logistic regression was used to analyze the independent risk factors of HPT and hypocalcemia in TT patients.Results:The postoperative parathyroid hormone level decreased in 41 cases (HPT group) and normal in 60 cases (control group). There were 24 patients with postoperative hypocalcemia symptoms (hypocalcemia symptoms group) and 77 patients without postoperative hypocalcemia symptoms (non-hypocalcemia symptoms group). The rate of using bipolar electric coagulation forceps in HPT group was significantly lower than that in control group: 31.71% (13/41) vs. 76.67% (46/60), while the rate of central lymph node dissection was significantly higher than that in control group: 82.93% (34/41) vs. 60.00% (36/60), and there were statistical differences ( P<0.01 and <0.05). Multivariate Logistic regression analysis result showed that TT combined with unilateral or bilateral central lymph node dissection was an independent risk factor for HPT in TT patients ( OR = 1.706 and 1.501, 95% CI 1.019 to 2.856 and 1.052 to 2.140, P<0.05). The preoperative serum calcium, postoperative serum calcium and postoperative parathyroid hormone in hypocalcemia symptoms group were significantly lower than those in hypocalcemia symptoms group: (2.32 ± 0.11) mmol/L vs. (2.37 ± 0.11) mmol/L, (2.16 ± 0.21) mmol/L vs. (2.25 ± 0.18) mmol/L and 3.00 (1.00, 5.45) ng/L vs. 19.90 (8.50, 33.80) ng/L, and there were statistical differences ( P<0.05 or <0.01). Multivariate Logistic regression analysis result showed that postoperative parathyroid hormone was an independent risk factor of hypocalcemia symptoms in TT patients ( OR = 0.927, 95% CI 0.883 to 0.974, P<0.01). In patients with HPT, the blood calcium at 1 week after surgery was significantly lower than that at 1 d after surgery: (2.07 ± 0.19) mmol/L vs. (2.17 ± 0.25) mmol/L, and there was statistical difference ( t = 2.05, P<0.05); the parathyroid hormone at 1 week after surgery was significantly higher than that at 1 d after surgery: 8.30 (3.55, 19.55) ng/L vs. 3.60 (1.00, 6.85) ng/L, and there was statistical difference ( Z = - 3.78, P<0.01). Conclusions:When performing TT, standardizing the surgical techniques, reducing unnecessary central lymph node dissection, and using bipolar electric coagulation forceps as much as possible can help to reduce the occurrence of postoperative HPT. The levels of postoperative parathyroid hormone and blood calcium should be promptly detected, the change of both should be given attention, and do a good job in preventing and treating hypocalcemia.

Objective:Exploring the association rules of factors influencing high hospitalization costs for cancer patients, providing references for hospitals to optimize medical cost management measures.Methods:In the inpatient case information system of a tertiary general hospital, the medical record homepages of inpatients in the DRG groups of the oncology department in 2022 were obtained. The upper four scores of hospitalization costs was used as the threshold for patient grouping. Patients with hospitalization costs≥this threshold were the high-cost group, while other patients were control group; 12 factors, including age, gender, and admission condition, etc, were considered as potential influencing factors of high hospitalization costs. FP-Growth and Apriori algorithms were used to excavate the potential association rules between the influencing factors of high hospitalization costs. Logistic regression was used to analyze the independent influencing factors of high hospitalization costs.Results:A total of 5 512 hospitalized patients were included, including 1 378 patients in the high-cost group. Thirteen validated strong association rules for factors influencing high hospitalization costs were obtained, of which the rule antecedents included age (≥70 years), number of days in hospital (≥7 days), other diagnoses (≥5), surgery, planned readmission, use of antibiotics, admission (general/critical), living admission score (61~99), level of care (level 1/level 2), non-day ward, criticality during hospitalisation. Logistic regression results showed that all nine influencing factors except gender, use of antibiotics, and readmission plans were independent influences on high hospitalization costs ( P<0.05). Conclusions:The joint application of FP-Growth and Apriori algorithm could effectively explore the association rules of high hospitalization costs for oncology patients. The early warning information mainly included the number of hospitalization days, the number of other diagnoses, surgeries, and so on. It was suggested that medical institutions can reasonably control the high hospitalization costs through clinical pathway management, diagnosis and treatment process reengineering, admission risk assessment, and multidisciplinary collaborative diagnosis and treatment strategies.

Objective:To develop an artificial intelligence（AI）-based sequential ultrasound-magnetic resonance imaging（US-MRI）diagnostic strategy to optimize the imaging workflow for ovarian masses.Methods:A total of 1 120 patients with pathologically confirmed ovarian masses who underwent both preoperative pelvic ultrasound and MRI between January 2021 and December 2023 at Women's Hospital，Zhejiang University School of Medicine were retrospectively included. Patients were randomly divided into the training（ n=672）and internal test set（ n=448）at a ratio of 6∶4. An external test set（ n=128）was established at the Forth Affiliated Hospital of School of Medicine. Deep learning was used for automated segmentation of MRI lesions，followed by radiomic feature extraction and machine learning classification to construct both a US-MRI multimodal model and sequential US-MRI strategy. Diagnostic performance and potential healthcare cost-saving effects were evaluated across strategies. Results:In the internal test set（ n=448），the AI-based sequential US-MRI strategy achieved a F1 score of 0.863 and a diagnostic accuracy of 82.14%，with no significant difference compared to the US-MRI multi-modal model（ P>0.05）. The sequential strategy identified 82 cases（18.30%，82/448）of patients as low-risk true negatives during initial ultrasound screening，suggesting a potential to reduce the need for MRI examinations in future clinical practice. In the external test set（ n=128），the strategy achieved an F1 score of 0.800 and a confirmed diagnosis rate of 85.94%，with a theoretical reduction of 26.56%（34 cases）in MRI utilization while maintaining a diagnostic accuracy rate higher than that of the multi-modal model（82.18%）. Conclusions:The AI-based US-MRI sequential diagnostic strategy demonstrates favorable diagnostic accuracy while offering the potential to optimize MRI utilization. This approach may enhance the efficiency of imaging resource allocation and reduce healthcare burden in the management of ovarian masses.

AIM:To evaluate the safety and toler-ability of single dose oral BTK inhibitor YZJ-3058 tablets under fasting conditions in healthy adults,as well as the pharmacokinetic and pharmacologi-cal characteristics of YZJ-3058 and its metabolites.METHODS:A total of 22 healthy subjects were en-rolled in this experiment and administered a single dose orally.They were divided into three groups:50 mg,100 mg,and 200 mg.Among them,2 sub-jects were enrolled in the 50 mg dose group,and 10 subjects were enrolled in the 100 mg and 200 mg dose groups,respectively.RESULTS:In healthy subjects,YZJ-3058 tablets were administered orally on an empty stomach at doses of 50,100,and 200 mg,with a median Tmax of 1.25 to 2.00 hours and an average Cmax of 62.85,89.44,and 99.20 ng/mL,re-spectively.The average AUC0-t was 183.87,297.72,and 453.98 h·ng-1·mL,respectively.The average AUC0-∞ was 189.30,321.33,and 551.44 h·ng-1·mL,and the median t1/2 was 1.16,5.06,and 7.97 hours,respectively.After a single oral administration of 50,100,and 200 mg YZJ-3058 tablets,the highest target occupancy rate was achieved at 4 hours.The average BTK occupancy rates at 24 hours after ad-ministration were 88.95％,96.73％,and 99.24％,re-spectively.The average BTK occupancy rates at 48 hours after administration were 75.65％,89.80％,and 96.68％,respectively.No serious adverse events or adverse events leading to withdrawal oc-curred,and all subjects had good tolerability.CON-CLUSION:YZJ-3058 tablets have good safety and tolerability for single oral administration on an empty stomach in healthy subjects within the dose range of 50-200 mg.Cmax and AUC increase with dose,with fast absorption and saturation.The ter-minal elimination rate gradually slows down with dose increase,and it has a significant and sus-tained occupying effect on BTK targets.

Objective To explore the influencing factors of abnormal increase of plasma water-soluble vitamins in patients with parenteral nutrition(PN).Methods A total of 862 hospitalized patients receiving nutritional diagnosis and treatment were enrolled.Daily water-soluble vitamin supply and total urine output were monitored.If patients underwent renal replacement therapy(RRT),the ultrafiltration volume was recorded.Plasma concentrations of nine water-soluble vitamins(Vit-C,B1,B2,B3,B5,B6,B7,B9 and B12)were measured.According to the test results,patients were divided into the accumulation group and the non-accumulation group.Renal function(BUN,Cr,UA),inflammatory indicators(CRP,WBC,NEU,SII)and nutritional indicators(ALB,PA,Hb,LYM)were compared between the two groups.Logistic regression was used to analyze the independent risk factors for the accumulation of water-soluble vitamins.Results There was a high incidence of abnormal plasma water-soluble vitamin levels,including Vit-B2(36.08%),Vit-B6(16.01%)and Vit-B5(13.81%).Compared with the non-accumulation group,the Vit-B2 accumulation group had higher levels of age,BUN,Cr,UA and NEU,and lower levels of ALB,PA and urine volume.The Vit-B5 accumulation group had higher levels of BUN,Cr,UA and NEU,and lower levels of LYM,Hb,ALB,PA and urine volume.Patients in the Vit-B6 accumulation group was older,with increased levels of BUN,Cr and UA,and decreased levels of LYM,Hb,ALB,urine volume and vitamin intake(P＜0.05).Multivariate Logistic regression analysis showed that the elevated level of BUN was independent risk factors for Vit-B2 accumulation,the elevated BUN and reduced urine volume were independent risk factors for Vit-B5 accumulation,and elevated BUN and Cr,as well as reduced urine volume,were independent risk factors for Vit-B6 accumulation.Receiver operating characteristic curve analysis showed that the area under the curve for BUN in predicting Vit-B2,B5 and B6 accumulation were 0.659(95%CI:0.620-0.697),0.728(95%CI:0.675-0.781)and 0.785(95%CI:0.738-0.831),respectively,with high specificity but low sensitivity.Conclusion The serum levels of water-soluble vitamins are affected by renal function.When implementing parenteral nutrition water-soluble vitamins supplementation,the patient's renal function status should be evaluated,and the risk of abnormal elevation of Vit-B2,B5 and B6 should be vigilantly monitored.

Objective To analyze the changes in serum miR-205,miR-23b and miR-25 levels and their correlation with the prognosis of patients with different severities of sepsis.Methods A retrospective study was conducted in 86 patients with sepsis admitted to our hospital between September 2021 and September 2023.Based on the severity of illness,patients were divided into mild(52 cases)and severe(34 cases)groups.Eighty healthy individuals undergoing medical check-ups during the same period were selected as controls.The patients were follo wed-up for 28 days and were then categorized into a survival group(68 patients)and a death group(18 patients).Real-time polymerase chain reaction was used to detect the serum miR-205,miR-23b,and miR-25 levels in patients and analyze their corre-lation with prognosis.Multivariate Cox regression analysis was used to analyze the risk factors affecting patient prognosis.The diagnostic value of serum miR-205,miR-23b,and miR-25 levels in assessing sepsis and their predictive value for prognosis were analyzed using receiver operating characteristic curves.Results Serum miR-205,miR-23b,and miR-25 levels were significantly lower in the two groups of patients with sepsis than in the control group(P＜0.05),and were significantly higher in the survival group than in the death group(P＜0.05).Their levels negatively correlated with prognosis.Heart rate and APACHE Ⅱ score were risk factors for a poor prognosis of patients with sepsis,whereas high serum miR-205,miR-23b,and miR-25 levels were protective factors(P＜0.05).The areas under the curve(AUC)for individual serum miR-205,miR-23b,and miR-25 levels and their combination to assess sepsis were 0.794,0.786,0.768,and 0.926,respectively.The AUC for predicting poor prognosis for patients were 0.776,0.762,0.797,and 0.918,respectively.Conclusion Serum miR-205,miR-23b,and miR-25 levels were reduced in patients with sepsis,and were closely correlated with patient prognosis.Thus,they may serve as serological biomarkers for assessing disease and predicting prognosis.

Objective To examine the association between lymphocyte subsets and renal clinicopathological characteristics as well as prognosis in patients with IgA nephropathy(IgAN).Methods The retrospective analysis included general clinical data and pathological examination results of IgAN patients diagnosed by renal biopsy at the Fourth Hospital of Hebei Medical University from January 2018 to January 2022.Correlation tests were conducted to examine the relationship between lymphocyte subsets and other significant clinicopathological parameters.The optimal cut-off value of CD4+T determined using the Youden index,and patients were grouped accordingly.Kaplan-Meier survival curves and Cox regression analyses were employed to compare the low and high CD4+T lymphocyte groups among IgAN patients,identifying factors influencing renal function progression.The endpoint event was defined as a decrease in estimated glomerular filtration rate(eGFR)of≥30%from baseline,progression to end-stage renal disease(ESRD)[eGFR<15 mL/(min·1.73 m2)or initiation of renal replacement therapy],or all-cause mortality.Results Low CD4+T lymphocytes were significantly positively correlated with blood IgA levels and the proportion of glomerular crescents in IgAN patients(all P<0.05).This study included a total of 53 IgAN patients,divided into two groups based on CD4+T lymphocyte counts:20 patients in the low CD4+T lymphocyte group and 33 patients in the high CD4+T lymphocyte group.In the low CD4+T lymphocyte group,there was a higher proportion of males and a lower proportion of glomerular crescents(P<0.05).Kaplan-Meier survival analysis revealed that patients with low CD4+lymphocytes had a significantly lower cumulative renal survival rate(Log-Rank test χ2=4.188,P=0.041).Cox regression analysis indicated that low CD4+lymphocytes were an independent risk factor for the progression of renal function decline in IgAN patients(HR=2.614,95%CI:1.006～6.788,P=0.048).Conclusions Patients with higher levels of CD4+T lymphocytes exhibit a lower risk of adverse renal outcomes.In contrast,patients with IgA nephropathy and low CD4+T lymphocyte counts tend to have poorer renal survival rates.
