The comorbidity rate of gastroesophageal reflux disease （GERD） and sleep disorders is high， and the two form a vicious circle through the “brain-gut axis”， which seriously impacts the patients’ quality of life. Traditional Chinese medicine （TCM）， guided by the core principles of “holistic concept” and “syndrome differentiation and treatment”， features multi-targeted therapeutic effects with minimal side effects， offering diverse intervention options for clinical practice. From the perspective of the “brain-gut axis”， this article reviews the relationship between the comorbidity of GERD and sleep disorders and systematically examines relevant research findings on how TCM regulates the “brain-gut axis” to intervene in this comorbid condition. The study reveals that the “brain-gut axis” may participate in the pathological progress of GERD accompanied by sleep disorders through pathways such as abnormalities in the secretion of brain-gut peptides （including gastrointestinal secretin）， as well as intestinal dysbiosis. By closely focusing on core pathogenic mechanisms such as “disharmony between the liver and stomach” and “insomnia due to stomach disharmony”， various approaches can be employed， including TCM formulas （e.g.， modified Sini powder combined with Zuojin pills）， external TCM therapies （e.g.， back-shu point digital acupressure）， and integrated traditional Chinese and Western medicine treatments （e.g.， modified Chaihu guizhi ganjiang decoction combined with proton pump inhibitors）. These methods can regulate the levels of neurotransmitters， gastrointestinal hormones， inflammatory factors， and the composition of intestinal microbiota associated with the “brain-gut axis”， thereby achieving simultaneous improvement in both GERD and sleep disorders.

Background: Malignant vasovagal syncope (VVS) is characterized by cardiac arrest lasting more than 3 seconds during a syncope episode or head-up tilt test (HUTT). We aim to conduct a risk assessment for potential malignant VVS before the HUTT by using economic, simple and convenient demographic data, in order to prevent adverse outcomes for pediatric VVS.Purpose: To explore the correlation between demographic factors and pediatric malignant VVS, and verify the value of these factors in early risk assessment for malignant VVS before HUTT, so as to optimize test safety and reduce adverse events. Methods: We conducted a retrospective analysis of the clinical data of 3,734 children who were initially diagnosed with VVS due to unexplained syncope and presyncope. Finally, 122 children who met the diagnostic criteria for malignant VVS were included in the malignant VVS group, and 661 children who did not meet the criteria during the same period were matched as the control group. By analyzing demographic data and other factors, we attempted to clarify the association between these factors and malignant VVS. Results: Linear relationship: age and body mass index (BMI) have independent protective effects on malignant VVS. For every 1-year increase in age and every 1 kg/m2 increase in BMI, the risk of malignant VVS decreases by 12% and 9%, respectively. Nonlinear relationship: When the age is <12.9 years old, for every additional year of age, the risk of malignant VVS decreases by 20%. For ages 12.9 years and above, the efficacy is not significant. There is no significant nonlinear relationship between BMI and malignant VVS. Conclusion Age and BMI are independent protective factors for pediatric malignant VVS. Before the age of 12.9 years, the incidence of malignant VVS gradually decreases with the increase in age, and thereafter there is no significant impact.

ObjectiveThis paper aims to observe the syndrome improvement and negative antigen conversion rate of Qingxuan Daozhi formula in the treatment of influenza in children （heat accumulation in the lung and stomach syndrome）. MethodsThrough a multi-center randomized controlled methodology design，confirmed influenza cases were collected from October 2022 to April 2023 in the pediatrics department of eight hospitals，such as Dongfang Hospital of Beijing University of Chinese Medicine. A total of 180 children with influenza and heat accumulation in the lung and stomach syndrome conforming to the standard were recruited through the clinic. The sick children meeting the inclusion criteria were randomly divided into groups by a block-randomized method. The children in the experimental group were treated with Qingxuan Daozhi formula for five days，and those in the control group were treated with Oseltamivir Phosphate Granules for five days. The primary efficacy indicator was the negative conversion rate of influenza antigen detection. Secondary efficacy indicators were the Canadian acute respiratory illness and flu scale （CARIFS） and the incidence of complications，severe cases， and critical cases. Follow-up observation was conducted on the day of enrollment，48 hours after medication，72 hours after medication， and （6+1） d after medication. ResultsOne hundred and eighty participants were randomly assigned to the experimental group （90 cases） or the control group （90 cases）. All participants were followed up during the study. Comparison of influenza antigen detection results in the primary efficacy indicators showed that the average time of negative influenza antigen conversion in the experimental group was （5.29±1.25） d，and that in the control group was （5.40±1.68） d，without a statistically significant difference. After five days of intervention，52 cases in the experimental group and 51 cases in the control group converted to negative，without a statistically significant difference. CARIFS score results in the secondary efficacy indicators showed that during 72 hours after intervention，there were statistically significant differences between the experimental group and the control group in three dimensions， including headache，muscle soreness， and the need for extra care （P<0.05）. On the （6+1） days after the intervention，the differences in both the experimental group and the control group were statistically significant in 10 dimensions， including sore throat，bad sleep，uncomfortable feeling，poor spirit and fatigue，crying more than usual，the need for extra care，symptom，function，influence on parents，and total score （P<0.05）. The comparison results within the group in the dimensional scores of symptom， function， and influence on parents，as well as the CARIFS total score showed that with the delay of follow-up time，scores of both groups decreased significantly，with a statistically significant difference （P<0.01）. Inter-group comparison results showed that the mean score of the experimental group was higher than that of the control group at the time of enrollment. With the progress of intervention，the score of the experimental group was significantly decreased compared with that of the control group. At the end of follow-up，the mean score of the experimental group was lower than that of the control group，with no statistically significant difference. In terms of the incidence of complications，severe cases， and critical cases， there were no complications，severe cases， and critical cases in the two groups，without a statistically significant difference. ConclusionThe symptom improvement effect and negative antigen conversion rate of Qingxuan Daozhi formula in the treatment of influenza in children （heat accumulation in the lung and stomach syndrome） are not inferior to Oseltamivir Phosphate granules， and children's acceptance is better. It can be more widely used in clinical treatment of influenza in children （heat accumulation in the lung and stomach syndrome）.

Objective: To investigate the incidence and influencing factors of new onset suicidal behaviors among junior and senior high school students, so as to provide evidence for early warning and intervention. Methods: Using a cluster sampling method, baseline data were collected from September to November 2023 among 2 379 adolescents selected from 2 junior high schools, 2 general senior high schools and 2 vocational senior high schools in Wuhan, Hubei Province, with follow up carried out from September to November 2024. Data were collected using the School Adaptation Scale, the Essential Resilience Scale, the Personal Social Support Scale, the Adverse Childhood Experiences Questionnaire, the Adolescent Life Events Scale, the Pittsburgh Sleep Quality Index, the Center for Epidemiologic Studies Depression Scale, and the Columbia-Suicide Severity Rating Scale. Multivariate Logistic regression analysis was used to identify factors influencing new onset suicidal behavior among junior and senior high school students. Results: Among junior and senior high school students without suicide risk at baseline, 53.55% remained stable risk free during follow up, while 13.28% developed new suicidal behavior during follow up, of which suicidal ideation, suicide plan and suicide attempts accounted for 11.69%, 8.83% and 6.52%, respectively. Multivariate Logistic regression revealed that increased depressive symptoms at follow up elevated the risk of overall new onset suicidal behaviors ( OR =4.14), ideation ( OR = 4.59), plans ( OR =4.24), and attempts ( OR =4.09); poor sleep quality also increased the risk of overall new onset suicidal behaviors ( OR =2.23), plans ( OR =2.03), and attempts ( OR =2.65) (all P <0.05). Non boarding junior and senior high school students had lower risks of overall new onset suicidal behaviors and ideation ( OR=0.70 and 0.49, respectively); secondary school students with academic performance ranking in the top 20%-30% of their class had a lower risk of new onset ideation ( OR =0.27); and those whose place of origin was outside the city had a lower risk of new onset plans ( OR =0.49) (all P <0.05). Conclusions New onset suicidal behaviors among junior and senior high school students exhibit dynamic and stage specific differences. Depressive symptoms serve as a common core risk factor across all stages, whereas sleep quality, academic performance, boarding status, and place of origin exert differential influences at distinct stages.

OBJECTIVE To investigate the molecular mechanism of Tiaozhong huashi decoction in improving gastroesophageal reflux disease （GERD） by regulating endoplasmic reticulum autophagy in rat esophageal interstitial cells of Cajal （ICC） through p62 signaling pathway.METHODS After establishing a rat GERD model via the weak acid intragastric administration and irregular diet， the rats were randomly divided into model group， western medicine group [1.56 mg/（kg·d） of mosapride， 3.125 mg/（kg·d） of lansoprazole] and low-， medium- and high-dose Tiaozhong huashi decoction [4.713， 9.425， 18.85 g/（kg·d）] groups. A blank group was also set up， with 8 rats in each group. The rats in each group were intragastrically administered with corresponding liquid or normal saline twice a day for 14 days. During the intervention period， the general conditions of rats’ hair， spirit， diet and defecation were observed. After the last gavage， the pathological changes of esophageal tissue and the ultrastructure of ICC were observed. The relative expression and positive expression levels of p62， autophagy-related protein 8 （ATG8）， 200 kDa FAK family kinase-interacting protein （FIP200） and Unc-51 like autophagy activating kinase 1 （ULK1） in esophageal tissue were detected.RESULTS Compared with the blank group， rats in the model group exhibited listlessness； thickening of the esophageal basal layer， elongation of lamina propria papillae with inflammatory cell infiltration； markedly dilated endoplasmic reticulum appearing as round vacuolar cisternae with ribosome detachment； and a small number of accumulated autophagosomes. The relative expression and positive expression levels of p62， ATG8， FIP200， and ULK1 were significantly decreased （ P ＜0.05）. Compared with the model group， the above pathological injuries in the medium- and high-dose Tiaozhong huashi decoction groups had all improved to varying degrees； the damaged endoplasmic reticulum structure was repaired， and no autophagosome accumulation was observed. In particular， the relative expression levels and positive expression levels of p62， ATG8， FIP200， and ULK1 in esophageal tissue of rats in the medium-dose Tiaozhong huashi decoction group were significantly increased （ P ＜0.05）.CONCLUSIONS Tiaozhong huashi decoction ameliorated esophageal mucosal injury in GERD rats， and its mechanism was possibly associated with activation of the p62 signaling pathway and restoration of the endoplasmic reticulum structure， morphology， and autophagic capacity of ICC.

Xuanbi Xuanfuhua Decoction(XBXFHD), as an empirical formula developed by Professor Xie Sheng, a National Qihuang Scholar, for the treatment of critical and severe respiratory diseases, has demonstrated definite efficacy in pulmonary sepsis, but its mechanism of action requires further investigation. This study explores the intervention effect of XBXFHD on pulmonary sepsis in rats from the perspective of regulating PANapoptosis. A rat model of pulmonary sepsis was successfully established by combined intratracheal injection of lipopolysaccharide (LPS), Staphylococcus aureus, and Escherichia coli, with control and different dosage drug groups established. HE staining, ELISA, Western blot, and flow cytometry were used to evaluate pathological changes in lung tissue, levels of inflammatory factors, cell apoptosis, expression of pan-apoptosis-related proteins (such as Caspase-3, Bcl-2, ZBP1, RIPK1, RIPK3, MLKL), and the proportion of CD4+ T cell subsets (Th17 and Treg). The results showed that XBXFHD significantly reduced alveolar inflammatory infiltration, congestion, and lung injury scores (P < 0.05), decreased the wet-to-dry weight ratio of the lungs, and reduced protein exudation in BALF. At the same time, XBXFHD inhibited the expression of Caspase-3, upregulated the expression level of Bcl-2 (P < 0.01), significantly reduced the apoptosis rate (P < 0.01), and downregulated the mRNA and protein levels of pan-apoptosis-related proteins (high-dose drug group P < 0.01). In addition, the formula reduced the proportion of Th17 (P < 0.01), increased the proportion of Treg (P < 0.05), downregulated the levels of pro-inflammatory factors (such as IL-18, IL-1β, TNF-α), and upregulated the levels of anti-inflammatory factors (such as IL-4, IL-10) (P < 0.05). The drug's effects were dose-dependent. These results indicate that XBXFHD improves pulmonary sepsis-related lung injury by inhibiting PANapoptosis-related proteins, regulating the Th17/Treg immune balance, and reducing inflammatory responses, with dose-dependent effects, providing experimental evidence for the clinical application of this formula.

Objective:To investigate the epidemiological dynamics and spatiotemporal diffusion trend of brucellosis in China from 2010 to 2024.Methods:Data on reported human brucellosis cases in mainland China from January 1, 2010, to December 31, 2024, were collected via the"China Information System for Disease Control and Prevention", including detailed information on the date of onset, gender, age, occupation, and residential address of the cases. The Joinpoint regression and spatial interpolation techniques were used to investigate the spatiotemporal dynamics and population distribution characteristics of human brucellosis in pastoral/semi-pastoral areas and other regions, as well as urban and rural areas, and explore the epidemic trends of the disease.Results:From 2010 to 2024, pastoral/semi-pastoral regions reported 252 094 brucellosis cases, with a mean annual incidence rate of 36.57±7.28 per 100 000. In contrast, other regions cumulatively recorded 519 748 cases during the same period, demonstrating a significantly lower mean annual incidence rate of 2.54±0.74 per 100 000. The incidence rate of human brucellosis in pastoral/semi-pastoral regions exhibited a declining-rebounding-declining trend. Specifically, the incidence rate decreased significantly from 2010 to 2017 (APC=-7.20; P<0.001) and increased notably from 2017 to 2021 (APC=18.00; P=0.015) with a decline again from 2021 to 2024 (APC=-7.53; P=0.027). In other regions, the incidence rate showed a fluctuating upward trend. Specifically, the incidence rate increased significantly from 2010 to 2015 (APC=20.37; P<0.001) and decreased notably from 2015 to 2018 (APC=-21.78; P<0.001), followed by an increase again from 2018 to 2024, a significant upward trend in incidence rate from 2018 to 2021 (APC=26.73; P<0.001) and a non-significant decline from 2021 to 2024 (APC=-0.99; P=0.735), resulting in the maintenance of a relatively high incidence level. Rural areas demonstrated significantly higher brucellosis incidence rates than urban settings (all P<0.001). Brucellosis exhibited a diffusion trend from the northern epidemic areas of China to neighboring regions, along with sporadic diffusion in southern regions between 2010 and 2024. The age structure of patients in pastoral/semi-pastoral areas differed significantly from that in other regions. Specifically, in pastoral/semi-pastoral areas, the incidence rate was higher among the 35-49 age groups, while in other regions, the incidence rate was higher among those aged 55-64. Conclusion:There are notable disparities in the incidence of human brucellosis between pastoral/semi-pastoral areas and other regions in China. Human brucellosis exhibits a diffusion trend from the northern epidemic areas of China to neighboring regions, along with sporadic diffusion in southern regions.

Objective This study aimed to adapt the data-driven Palliative Care Outcomes Collaboration(PCOC)model to the local context and evaluate its feasibility and preliminary effectiveness in a palliative care unit in China,with the goal of informing its broader integration into national palliative care practice.Methods Based on international experience,a localized implementation protocol for the PCOC model was developed through expert con-sultations and a pilot study.The protocol incorporated key elements including organizational and managerial sup-port,team training and capacity building,information system integration,supervision and feedback mechanisms,pro-cess optimization,and data-driven decision-making.From June to December 2023,the protocol was piloted in the palliative care unit of a tertiary cancer hospital in Changsha,China.Implementation outcomes were assessed by comparing patients' urgent care response rates,symptom stability rates,and symptom improvement rates between the first 1～3 months and 4～6 months after implementation.Results During the study period,a total of 355 inpatients were enrolled,with the PCOC assessment achieving full coverage(100％)and a completion rate of 97.78％.There was no statistically significant difference in the urgent needs response rate between the first 1～3 months and the 4～6 months after the implementation of the PCOC model(P=0.533).However,compared to the first 1～3 months af-ter implementation,patients in the 4～6 months period showed significantly higher symptom stability rates for pain,psychological/spiritual issues,and family/caregiver problems,as well as a higher improvement rate for pain(P＜0.05).Conclusion The localized PCOC implementation protocol facilitates standardized assessment and symptom manage-ment,and its application can enhance the quality of palliative care.

Polycystic ovary syndrome （PCOS）， a common reproductive endocrine disorder in women， is one of the leading causes of ovulatory infertility in women of reproductive age. Due to its heterogeneous etiology， complex symptoms， and challenging treatment， PCOS has become a focal point of research in gynecological and reproductive medicine globally. The pathogenesis of PCOS is complex and may involve regulatory mechanisms such as inflammatory responses， oxidative stress， and cellular autophagy. Crown-like structures （CLSs） refer to pro-inflammatory microenvironments formed by macrophages engulfing adipocytes. The inflammatory disorders induced by CLSs are one of the key factors contributing to the development of PCOS and its complications. Current studies have indicated that the obese status in PCOS accelerates the formation of CLSs， and the density of CLSs can predict the progression of metabolic disorders and influence the outcomes of various metabolic diseases. Traditional Chinese Medicine （TCM） offers the unique advantages of a holistic view， four diagnostic methods， and syndrome differentiation and treatment to ameliorate the symptoms and signs of PCOS through multiple levels， pathways， and targets. Although studies on the mechanisms of metabolic diseases and CLS formation have been reported in China and abroad， there is still a lack of literature on the correlation between CLSs and PCOS， as well as reviews on TCM interventions targeting CLSs for treating this disease. Therefore， this paper summarized the correlation between obese PCOS and CLSs and reviewed recent studies on TCM interventions based on CLS formation （adipose tissue-macrophage inflammatory crosstalk） in the treatment of obese PCOS， aiming to provide new research perspectives for the prevention and treatment of PCOS using TCM.

Objective:To explore the mediating role of cyber self-efficacy between technological anxiety and the willingness to use tele-rehabilitation among patients with chronic obstructive pulmonary disease (COPD) .Methods:From September 2023 to May 2024, a convenience sampling method was used to select COPD patients receiving treatment in the Inpatient Department of Zhoushan Hospital as the research subjects. A General Information Questionnaire, the Scale of Willingness to Use Tele-Rehabilitation for COPD Patients, the Technological Anxiety Scale, and the Cyber Self-Efficacy Questionnaire were used to collect data.Results:A total of 312 questionnaires were distributed, and 305 valid questionnaires were retrieved, with an effective recovery rate of 97.76%. The average score of the Scale of Willingness to Use Tele-Rehabilitation for the 305 COPD patients was (76.52±5.30) , and the average item score was (2.94±0.20) . Cyber self-efficacy played a partial mediating role between technological anxiety and the willingness to use tele-rehabilitation, accounting for 8.21% of the total effect (-0.048/-0.585) .Conclusions:The level of willingness to use tele-rehabilitation among COPD patients needs to be enhanced. The professional values of COPD patients not only directly affect their level of willingness to use tele-rehabilitation, but also influence their technological anxiety, which in turn affects their cyber self-efficacy, ultimately having an indirect impact on the willingness to use tele-rehabilitation. Nursing staff should strengthen the professional values of COPD patients, help them overcome technological anxiety, and enhance their cyber self-efficacy, so as to increase their willingness to use tele-rehabilitation.
