OBJECTIVE To study the efficacy of Tianjiang xueshuantong pills in the treatment of coronary heart disease. METHODS In accordance with the common pathogenesis of coronary heart disease， acute myocardial ischemia model， hyperlipidemia model， blood stasis model， and carotid artery thrombosis model were established using Wistar rats or SD rats as the experimental subjects. The effects of Tianjiang xueshuantong pills administered at high， medium， and low doses （0.6， 1.2 and 2.4 g/kg） on hemodynamic parameters and myocardial enzyme markers [lactate dehydrogenase （LDH）， creatine kinase-MB （CK- MB）]， oxidative stress factors [superoxide dismutase （SOD）， malondialdehyde （MDA）， glutathione （GSH）]， inflammatory cytokines [tumor necrosis factor-α （TNF-α）， interleukin-6 （IL-6）， IL-1β， monocyte chemotactic protein-1 （MCP-1）， intercellular adhesion molecule-1 （ICAM-1）]， myocardial infarction percentage， serum lipid indexes [total cholesterol （TC）， triglycerides （TG）， low-density lipoprotein （LDL）， high-density lipoprotein （HDL）]， platelet aggregation function 话：022-84845240。E-mail：jiangx@tjipr.com [maximum aggregation rate （MAR）]， and thrombus formation indexes [thrombosis time， thrombus mass， thrombus protein content， plasminogen activator inhibitor-1 （PAI-1）， and tissue-type plasminogen activator （t-PA）] were evaluated in the rat models. RESULTS In myocardial ischemia tests， Tianjiang xueshuantong pills significantly reduced the percentage of myocardial infarction and the levels of CK-MB， LDH， MDA， GSH， IL-6， TNF-α， IL- 1β， and MCP-1 in serum （P＜0.05 or P＜0.01）. In hyperlipidemia tests， high dose of Tianjiang xueshuantong pills significantly reduced the serum levels of TC， LDL and significantly increased the level of HDL in rats after 2 weeks and 4 weeks of administration. In blood stasis tests， different doses of Tianjiang xueshuantong pills significantly reduced MAR of rats （P＜0.01）. In artery thrombosis tests， high dose of Tianjiang xueshuantong pills significantly prolonged the time of thrombosis formation （P＜ 0.01）， significantly reduced the weight and protein content of thrombus and the level of PAI-1 in serum （P＜0.01）. CONCLUSIONS Tianjiang xueshuantong pills exert therapeutic effects on coronary heart disease through multi-dimensional synergistic actions， including anti-myocardial ischemia， lipid-lowering， and anti-thrombotic effects.

Objective To explore the expression and clinical significance of Yes-associated protein 1(YAP1)in esophageal squamous cell carcinoma.Methods Immunohistochemical method was used to detect YAP1 expression in 439 cases of esophageal squamous cell carcinoma.The differences of YAP1 expression and clinical parameters were analyzed between YAP1 positive group and YAP1 negative group.Kaplan-Meier curve was used to analyze the influence of YAP1 expression on survival of patients.Results The positive rate of YAP1 in esophageal squamous cell carcinoma was 30.52% .The tumor invasion was deeper in YAP1 positive group(P＜0.001).Kaplan-Meier survival analysis showed that YAP1 positive patients had longer disease-free survival(DFS)and overall survival(OS)among patients surviving longer than 30 months(P＜0.05).The multivariate Cox regression analysis showed that the invasion depth of tumor was an independent factor affecting DFS(HR=1.371,95% CI 0.993-1.894,P=0.035)and OS(HR=1.489,95% CI 1.066-2.080,P=0.020).Conclusions YAP1 has a certain percentage of positive rate in esophageal squamous cell carcinoma;for patients with survival longer than 30 months,YAP1 positive indicates a better prognosis.

Objective: To understand the trends in malnutrition among primary and middle school students of Han nationality in Hainan Province from 2005 to 2019, so as to provide a basis for improving nutrition intervention measures for children and adolescents. Methods: A sample of 32 949 Han nationality primary and middle school students aged 7-18 years old in Hainan Province were investigated in 2005, 2010, 2014 and 2019 based on national survey on student physical fitness and health. The Malnutrition Screening Standard of Schoolage Children and Adolescents was used to screen malnutrition. Statistical analysis was performed using the χ2 test and the χ2trend test. Results: In the four surveys conducted during 2005 to 2019, the prevalence of malnutrition among primary and middle school students were 22.12%, 18.80%, 15.89% and 9.56%, respectively, with an increase of -12.56% and an average annual increase of -5.82%. The decreasing trend of malnutrition by year was statistically significant (χ2trend=600.72, P<0.01), and the proportion of emaciation type was the highest (8.87%-20.15%). The detection rates of malnutrition among all students aged 7 to 18 showed a decreasing trend from 2005 to 2019 (χ2trend=56.44, 60.04, 61.48, 42.49, 51.81, 50.81, 72.86, 101.34, 86.38, 24.81, 17.72, 10.38, P<0.01). From 2005 to 2019, the detection rates of malnutrition in boys were higher than that of girls (in 4 surveys), and that in rural students from 2005 to 2014 of 3 surveys were higher than that in towns (χ2=92.07, 35.16, 25.29, 29.98; 64.35, 4.26, 6.32, P<0.05). Conclusions The malnutrition of Han nationality primary and middle school students aged 7-18 years in Hainan Province show a trend of improvement year by year from 2005 to 2019, despite the overall high detection rate. Wasting is the most common type of malnutrition. The epidemic of malnutrition varies by age, sex and areas. Further targeted measures should be taken to strengthen intervention in the diet of primary and middle school students, to improve the nutritional status of children and adolescents.

Objective: To examine the causal relationship between inflammatory factors and breast cancer using two-sample Mendelian randomization (MR) approach, so as to provide the basis for the prevention and treatment of breast cancer. Methods: Data of 91 inflammatory cytokines (n=14 824) and 5 subtypes of breast cancer (n=247 173) were collected from genome-wide association studies (GWAS). Single nucleotide polymorphism (SNP) associated with 91 inflammatory factors were selected as instrumental variables. MR analyses were performed using the inverse-variance weighted (IVW) method with inflammatory factors as exposure factors and breast cancer as outcome variables. The risk of type I error and the effect of multiple testing were reduced using the FDR correction method. The stability and reliability of the results were verified using Steiger test of directionality, MR-Egger regression, MR-PRESSO test and leave-one out method. Results: Twenty-three inflammatory factors, including β nerve growth factor, interleukin-5, cystatin D and C-X-C chemokine ligand 1 were statistically associated with breast cancer (all P<0.05). After FDR adjustment, only evaluated abundance of oncostatin-M was found to be statistically associated with an increased risk of Basal-like (triple-negative) breast cancer (OR=1.186, 95%CI: 1.081-1.302, P=0.001, q=0.029), and the other 22 inflammatory factors had a high risk of type I error (all q>0.1). The sensitivity analysis indicated that the results were robust. No instrumental variables were found to have a significant impact on the results, which could exclude the influence of heterogeneity, horizontal pleiotropy, and reverse causality on the outcome. Conclusion The increased abundance of oncostatin-M may increase the risk of Basal-like (triple-negative) breast cancer.

Purpose To investigate the expression of fork-head box protein A1(FOXA1)in esophageal squamous cell car-cinoma(ESCC)and its association with clinicopathologic char-acteristics and prognosis.Methods Immunohistochemistry was used to detect FOXA1 protein expression in 532 cases of esopha-geal squamous cell carcinoma.The correlation between FOXA1 protein expression and clinicopathologic features and prognosis of patients was analyzed.Results In 532 cases of esophageal squamous cell carcinoma,183 cases overexpressed FOXA1 pro-tein(34.4％).FOXA1 overexpression was associated with ES-CC vascular infiltration(P=0.032),poorly differentiation(P=0.032),and tumor size(P＜0.001).The overall survival(OS)and disease free survival(DFS)of patients with stage Ⅰ+Ⅱ esophageal squamous cell carcinoma with high FOXA1 ex-pression tended to be poor(OS:P=0.094;DFS:P=0.107).In ESCC patients with survival longer than 24 months,the high FOXA1 expression group had significantly shorter OS and DFS(OS:P=0.048;DFS:P=0.047).Multivariate survival anal-ysis showed that the depth of tumor invasion was an independent prognostic factor affecting the prognosis of esophageal squamous cell carcinoma.Conclusion FOXA1 is overexpressed in e-sophageal squamous cell carcinoma,and its high expression is related to tumor size,vascular infiltration and poorly differentia-tion.Patients with high FOXA1 expression tended to have poor prognosis in OS and DFS.When OS and DFS≥24 months,high FOXA1 expression may be used as a reference indicator for poor prognosis in ESCC patients.

Objective:To investigate the knowledge and practice of the Sixth Chinese national consensus report on the management of Helicobacter pylori ( H. pylori) infection (treament excluded) (referred to as sixth national consensus)and 2022 Chinese national clinical practice guideline on H. pylori eradication treatment (referred to as guideline) among gastroenterologists in China, so as to provide out relevant training in the future. Methods:A questionnaire was designed according to sixth national consensus and guideline, including knowledge and practice of sixth national consensus and guideline, and the detection, indications of eradication, the relationship between infection and gastrointestinal microbiota, and eradication of H. pylori. From November 1 to 30 in 2023, the questionnaire-based survey was conducted among 1 506 gastroenterologists from secondary and tertiary hospitals of 24 provinces, autonomous regions and municipalities in China with convenience sampling method using the "Questionnaire Star" online questionnaire platform and the questionnaire link was sent by WeChat. Descriptive methods were used for statistical analysis. Results:A total of 1 442 valid questionnaires were collected. The awareness rate of sixth national consensus and guideline of gastroenterologists was 83.7% (1 207/1 442), and 47.2% (680/1 442) had read the relevant content in detail. Urea breath test (97.4%, 1 404/1 442) was the most commonly used method for diagnosing current H. pylori infection, however, more than half of the physicians chose serological test (53.3%, 769/1 442) for the diagnosis of current infection. The common indications of H. pylori eradication could be identified by 84.3%(1 215/1 442) of gastroenterologists. The most well-known eradication regimen was bismuth quadruple regimen (98.5%, 1 421/1 442), while some physicians still believed that the standard triple regimen (31.8%, 459/1 442) and sequential regimen (21.9%, 316/1 442) were recommended by the guideline. A further 20.2% (291/1 442) frequently prescribed a triple regimen combined with gastric mucosal protectants and the awareness rate of high-dose dual regimen was 59.1% (852/1 442). Amoxicillin + clarithromycin (65.4%, 943/1 442) and amoxicillin+ furazolidone (20.1%, 290/1 442) were commonly used antibiotic combinations in bismuth quadruple therapy. Potassium-competitive acid blockers and double-dose proton pump inhibitors were commonly used in bismuth quadruple therapy by 45.4% (655/1 442) and 46.0% (664/1 442) of physicians, respectively. For patients with multiple failed eradications, furazolidone was the most commonly used antibiotic for re-eradication(71.7%, 1 034/1 442). Conclusion:The knowledge and practice of gastroenterologists on H. pylori infection in China deviates from the new consensus and guideline, and more publicity and training should be carried out in future to improve the ability of gastroenterologists to standardise the diagnosis and treatment of H. pylori infection.

Traditional Chinese medicine (TCM) has played an important role in the prevention and treatment of Coronavirus disease 2019 (COVID-19) epidemic in China. The integration of Chinese and Western medicine is an important feature of Chinese COVID-19 prevention and treatment. According to a series of evidence-based studies, TCM can reduce the infection rate of severe acute respiratory syndrome coronavirus 2 in high-risk groups. For patients with mild and moderate forms of COVID-19, TCM can relieve the related signs and symptoms, shorten the period of nucleic-acid negative conversion, and reduce conversion rate to the severe form of the disease. For COVID-19 patients with severe and critical illnesses, TCM can improve inflammatory indicators and blood oxygen saturation, shorten the hospital stay, and reduce the mortality rate. During recovery, TCM can improve patients' symptoms, promote organ function recovery, boost the quality of patients' life, and reduce the nucleic-acid repositive conversion rate. A series of mechanism research studies revealed that capability of TCM to treat COVID-19 through antiviral and anti-inflammatory effects, immune regulation, and protection of organ function via a multicomponent, multitarget, and multipathway approach.

ObjectiveTo investigate the status of different antiretroviral therapy（ART） initiation times in patients with HIV/AIDS and analyze the relevant characteristics and influencing factors of delayed ART. MethodsFrom December 2018 to December 2020， a survey was conducted among adult HIV/AIDS patients treated in 28 designated AIDS prevention and treatment institutions in Beijing， Shanghai， Guangdong， Jiangsu， Henan， Jiangxi， Guangxi， Yunnan and other places. Data of the basic demographic information， lifestyle and chronic disease prevalence， and characteristics of diagnosis and treatment were collected. The characteristics and related factors of delayed ART were compared and analyzed. ResultsThe median age of 1 741 patients was 41 years old （IQR： 32‒52）. The initial CD4 count of most patients was less than 200 cells·μL^-1（51.4%）. Among them， 1 027 patients had delayed ART （59.0%）， and the association between ART initiation time and initial CD4 count varied with the time of diagnosis of HIV infection. Multivariate logistic analysis showed that the older age （aOR=0.99， 95%CI： 0.98‒0.99） was associated with a higher rate of starting ART within 1 month after diagnosis， while those diagnosed before 2017 and with the initial CD4 count >200 cells·μL^-1 were more likely to delay ART. Delayed initiation of ART may be a risk factor for poor sleep quality and co-infection in HIV/AIDS patients. ConclusionWith the expansion of free ART in China， the proportion of delayed ART with HIV/AIDS shows a downward trend. Timely ART management should be strengthened for the young HIV/AIDS patients and patients with high CD4 counts.
