Epileptogenesis is a dynamic process of gradual progression from normal developing brain to pathological epileptic brain， which is the latent and budding stage of epilepsy. Combining the understanding of epileptogenesis in children from Western medicine and traditional Chinese medicine （TCM）， we proposed that the viewpoints of constitutional transformation， phlegm pathogen inducing epilepsy， and brain collateral damage， which correspond to key pathological mechanisms， namely gene polymorphism， immunoinflammation， and microvascular dysfunction of the blood-brain barrier， respectively. Based on these insights， strategies for prevention and treatment of epileptogenesis in children， as well as potential research directions are explored.

OBJECTIVE To evaluate the clinical efficacy and safety of Jianwei xiaoshi oral liquid in the treatment of functional dyspepsia （FD） in children， and provide evidence-based basis for clinical use of the drug. METHODS Retrieved from CNKI， VIP， Wanfang， CBM， Cochrane Library and PubMed， randomized controlled trials （RCTs） about Jianwei xiaoshi oral liquid in the treatment of FD in children were collected from the inception to Apr. 2024. The control group was treated with conventional western drugs （including gastrointestinal motion-promoting， antacids or acid-suppressing drugs）， and the trial group was treated with Jianwei xiaoshi oral liquid alone or combined with conventional Western drugs （drug dosage and course of treatment were the same as the control group）. Meta-analysis was performed using RevMan 5.3 software after quality evaluation with the Cochrane risk bias assessment tool 6.1. RESULTS Totally 16 literature were employed which included 1 962 patients. The results of meta-analysis showed that the total clinical effective rate of Jianwei xiaoxi oral liquid in the treatment of FD in children of trial group was significantly higher than that of the control group [RR＝1.18， 95%CI （1.13， 1.22）， P＜0.000 01]. In this study， subgroup analysis was conducted on the usage and dosage， course of treatment， and combination or not in trial group， as well as the type of conventional Western drugs. The results showed that the total clinical effective rate of trial group was significantly higher than that of control group； the relief time of abdominal distension and abdominal pain in trial group [MD＝－2.54， 95%CI （－3.10， －1.98）]， loss of appetite relief time [MD＝－2.12， 95%CI （－2.63， －1.61）]， nausea and vomiting relief time [MD＝－1.70， 95%CI （－2.27， －1.14）]， and belching relief time [MD＝－1.61， 95%CI （－2.44， －0.78）] were shorter than that of the control group significantly （P＜0.05）. In addition， compared with control group， the levels of gastrin [SMD＝1.63， 95%CI （0.98， 2.29）] and motilin [SMD＝2.06， 95%CI （1.58， 2.54）] as well as gastric antral emptying rate [MD＝5.99， 95%CI （2.78， 9.21）] in trial group were increased significantly， while the level of somatostatin was decreased significantly [SMD＝－1.30， 95%CI （－1.57， －1.02）] （P≤0.000 3）. CONCLUSIONS Jianwei xiaoshi oral liquid， whether used alone or in combination with other medications， and regardless of the treatment course or dosage and usage， is effective in treating FD in children， with good safety.

Epilepsy is a chronic neurological disorder that often begins in childhood and can extend over the entire life course; therefore, it is necessary to establish a long-term, systematic life-course management model. Whole life-cycle disease management emphasizes interventions at key points in time and focuses on diagnosis and treatment points at all stages of life and disease processes. Guided by the concept of holism and preventive treatment, this article discussed the application strategies of TCM in the prevention, control, treatment, health and management of epilepsy in children at different stages. In the prevention period, the disease should be prevented first, and early screening should be carried out; in the control period, the disease should be prevented from changing, and the early intervention of Chinese materia medica should be carried out; during the treatment period, the combination of disease and syndrome and dynamic syndrome differentiation by stages were adopted; during the rehabilitation period, the treatment of different diseases with the same treatment should be emphasized to manage the comorbidity and improve the prognosis; in the long-term management period, the prevention and recovery after stroke should be focused on, and the comprehensive management scheme of TCM in the transition period from children to adults should be put forward. This article systematically expounded the role of TCM in improving seizure control rate and prognosis in the whole life-cycle management of childhood epilepsy, and actively explored the construction of the whole process health management system of chronic diseases.

Objective:To explore the clinical characteristics and distribution of Tranditional Chinese Medicine (TCM) syndrome types of refractory tic disorders in children based on clustering analysis.Methods:A cross-sectional study. 183 children aged 3-18 years with refractory tic disorders from pediatric encephalopathy outpatient department of the First Teaching Hospital of Tianjin University of Traditional Chinese Medicine who met the inclusion criteria from October 2015 to January 2022 were recruited. Frequency descriptive analysis, systematic clustering analysis and principal component analysis were conducted by Microsoft Office Excel 2016 and IBM SPSS Statistics 26.0 to explore the clinical characteristics and syndrome distribution of the disease.Results:The TCM symptoms of 183 children with refractory tic disorders were clustered into 6 categories, and finally 5 types of syndrome were obtained, among which the syndrome of spleen deficiency and liver hyperactivity mixed with dampness accounted for the largest proportion (27.32%), followed by the syndrome of phlegm-fire disturbing spirit (21.31%), the syndrome of wind-heat invading lung (18.03%), the syndrome of phlegm-qi stagnation (17.49%), and the syndrome of dampness and yin deficiency (15.85%).Conclusion:Through the mining and analysis of the outpatient information of pediatric encephalopathy in our hospital, the common syndrome differentiation types of refractory tic disorder are obtained, which can provide a reference for the TCM syndrome differentiation types of refractory tic disorder in children.

Objective To study the value of postmortem imaging on the diagnosis of intestinal perforation.Method Postmortem imaging(PMCT and PMCTA)data of 2 intestinal perforation deaths(and 4 controlled cases)were reviewed retrospectively.Diagnosing capacities of intestinal perforation by postmortem imaging method were further investigated.Results PMCT is sensitive in detecting the free air and liquid induced by intestinal perforation.PMCT can sometimes detect the gravity-dependent purulent secretions in the abdominopelvic cavity.PMCTA can visualize the extravasation of contrast agent from the perforation,which can be used to locate the accurate perforation region.Conclusion Postmortem imaging method(PMCT and PMCTA)is an important tool for the diagnosis of intestinal perforation,which can not only be used as a forensic diagnosis method,but is also useful to locate the perforation site before an forensic autopsy.

Objective:To establish the allowable total error (TEa) of the national external quality assessment (EQA) program in line with the current quality level of serum folate measurement in China.Methods:The data of serum total folate test in the clinical laboratory of a hospital in Beijing in 2016 were collected, and the Stata SE 15 software was used for Monte Carlo simulation to obtain the false-negative rate under different bias and inaccuracy conditions. The Origin Pro 9.1 software was used to make the contour figure. The TEa of serum total folate test is derived based on the acceptable false-negative rate. National EQA data of serum total folate in 2020 were collected to calculate the pass rate of participating laboratories and the laboratory pass rate of quality control products at each level under the five TEa derived from the analysis performance on clinical outcomes, biological variation, and the evaluation criterion of national EQA.Results:Based on the influence of analytical performance on clinical outcomes, the TEa was 10%. Under this TEa, the pass rate of the first EQA program of serum total folate in 2020 was more than 80%, and the pass rate of the second time was 73.1%. Under the minimum (46.57%) and appropriate level of TEa (15.52%) derived from biological variation and national EQA evaluation criterion, the pass rate of serum total folate in the two EQA programs in 2020 exceeded 85%.Conclusion:The analytical performance of serum total folate in China cannot meet the requirements of TEa derived based on the effect of analytical performance on clinical outcomes. An appropriate level of TEa derived based on biological variation (15.52%) is suggested as the recommended criterion for the TEa of serum total folate test.

OBJECTIVE: To understand the mental health status of subway employees, and to explore the relationship among their mental health, psychological capital and work engagement. METHODS: Using the typical sampling method, a total of 2 758 subway employees from a rail transit group Co., Ltd in a city were selected as the study subjects. The Symptom Check List 90, Psychological Capital Questionnaire, and Utrecht Work Engagement Scale were used to investigate the mental health, psychological capital and work engagement of the study subjects. RESULTS: The screening positive rate of mental disorder of the study subjects was 15.6%(431/2 758), and the median scores of mental health, psychological capital, and work engagement were 108, 109, and 62 points, respectively. The mental health scores of the study subjects were negatively correlated with their psychological capital and work engagement scores [Spearman correlation coefficient(r_S) were-0.55 and-0.57, respectively, P<0.01]. The psychological capital score was positively correlated with the work engagement score(r_S=0.70, P<0.01).Mental health played a partial mediating role in the influence of psychological capital on work engagement(mediating effect was 0.07, 95% correlation coefficient: 0.06-0.08, P<0.01). CONCLUSION: The mental health status of the subway employees is good. Psychological capital of subway employees can not only directly affect work engagement, but also indirectly affect work engagement by influencing mental health.

Objective Accurate measurement of aldosterone is critical in the diagnosis of primary aldosteronism. We compared the harmonization of three assays including isotope dilution liquid chromatography-tandem mass spectrometry (ID-LC-MS/MS) and two chemiluminescence immunoassays (CLIAs:system A and system B) for the aldosterone measurement. Methods A total of 45 plasma samples, 4 quality control materials, 5 lyophilized bovine serums, and 3 fresh frozen human serum pools were measured by three assays respectively. Based on CLSI EP15-A3 rule, the precision was assessed by coefficient of variance. Deming regression and Bland&Altman plots was performed for method comparison, and correlation coefficient was calculated for concordance (CCC). Results All three methods met the performance criteria based on desirable biological variation for precision (<7.35％). System A showed a relevantly good correlation and comparability with ID-LC/MS/MS (R2=0.985, CCC=0.967), while System B showed relevantly bad correlations and comparability with both System A (R2=0.538, CCC=0.605) and ID-LC/MS/MS (R2=0.547, CCC=0.528).. However, the average relevant bias of two CLIAs exceeded the bias requirement derived from biological variation (18.60％). Conclusion Significant differences were found in the measurement of plasma aldosterone using ID-LC-MS/MS and two CLIAs, which urges the establishment of traceability hierarchy and improvement of reagents' specificity for standardization of aldosterone measurement in clinical settings.

OBJECTIVE:To evaluate the efficacy and safety of Bacterial lysates(hereinafter referred to as"Broncho-Vaxom") for recurrent respiratory tract infections (RRTIs) of children,and to provide evidence-based reference for clinic. METHODS:Retrieved from PubMed,EMBase,Cochrane Library,CBM,CNKI,Wanfang database and VIP database,domestic and foreign published randomized controlled trials (RCTs) about Broncho-Vaxom (trail group) vs. placebo (control group) for RRTIs of children were collected during database establishment to Jan. 2018. After literature scanning and data extraction,the risk of bias of included trials were evaluated by using Cochrane 5.1.0 risk bias evaluation tool. Meta-analysis was performed by using Rev Man 5.3 software. RESULTS:A total of 13 RCTs involving 1 228 children were included. The results showed that the trial group was superior to control group in frequency of respiratory infection [MD＝－1.14,95%CI(－1.29,－0.99),P＜0.001],total response rate [RR＝9.47,95%CI(2.33,38.54),P＝0.002],the time of antibiotics use [MD＝－4.36,95%CI(－6.52,－2.21),P＜0.001], infection duration [MD＝－3.89,95%CI(－4.47,－3.04),P＜0.001],febrile time [MD＝－1.81,95%CI(－3.40,－0.22),P＝0.03],serum immunoglobulin (Ig)G level [MD＝1.25,95%CI(0.13,2.37)),P＝0.03],IgA level [MD＝0.77,95%CI(0.07, 1.46),P＝0.03] and the level of T cell subgroup CD4+[MD＝1.33,95%CI(0.90,1.76),P＜0.001] and CD8+[MD＝0.64,95%CI (0.24,1.04),P＝0.002],there was statistical significance. Trail group was similar to control group in respect of cough time [MD＝－6.00,95%CI(－13.86,1.86),P＝0.13] and IgM level [MD＝－0.10,95%CI(－0.32,0.12),P＝0.39] and the incidence of ADR [RR＝0.76,95%CI(0.43,1.35),P＝0.35]. CONCLUSIONS:The current evidence shows that Broncho-Vaxom could effectively prevent the RRTIs of children with good safety.
