Objective To explore the clinical features and prognostic factors of gastric cancer patients liver metastasis.Methods Data from 7055 patients with gastric cancer were retrieved from Surveillance,Epidemiology and End Results(SEER)database between 2010 and 2015.The patients were divided into the liver metastases group(901 cases)and the non-liver metastases group(6154 cases)according to whether liver metastasis occurred.Univariate and multivariate Cox regression were used to analyze the prognostic risk factors,and the Kaplan-Meier method was used for survival analysis.Results There was a significant difference in age,gender,race,T stage,N stage,primary surgery,radiotherapy and tumor size between the two groups(P<0.05),and the median survival time of patients in the liver metastases group was 6 months,non-liver metastases group was 25 months.Cox regression analysis showed that age(P=0.009),tumor grade(P<0.001),surgery(P<0.001)and chemotherapy(P<0.001)were the main factors affecting the prognosis of gastric cancer with liver metastases.Conclusion Age,tumor grade,surgery and chemotherapy were the prognostic risk factors for gastric cancer with liver metastases.A nomogram based on age,tumor grade,surgery and chemotherapy has a good survival prediction significance for gastric cancer with liver metastases.

Background::Oral anti-coagulants (OAC) are the intervention for the prevention of stroke, which consistently improve clinical outcomes and survival among patients with atrial fibrillation (AF). The main purpose of this study is to identify problems in OAC utilization among hospitalized patients with AF in China.Methods::Using data from the Improving Care for Cardiovascular Disease in China-Atrial Fibrillation (CCC-AF) registry, guideline-recommended OAC use in eligible patients was assessed.Results::A total of 52,530 patients with non-valvular AF were enrolled from February 2015 to December 2019, of whom 38,203 were at a high risk of stroke, 9717 were at a moderate risk, and 4610 were at a low risk. On admission, only 20.0% (6075/30,420) of patients with a diagnosed AF and a high risk of stroke were taking OAC. The use of pre-hospital OAC on admission was associated with a lower risk of new-onset ischemic stroke/transient ischemic attack among the diagnosed AF population (adjusted odds ratio: 0.54, 95% confidence interval: 0.43–0.68; P <0.001). At discharge, the prescription rate of OAC was 45.2% (16,757/37,087) in eligible patients with high stroke risk and 60.7% (2778/4578) in eligible patients with low stroke risk. OAC utilization in patients with high stroke risk on admission or at discharge both increased largely over time (all P <0.001). Multivariate analysis showed that OAC utilization at discharge was positively associated with in-hospital rhythm control strategies, including catheter ablation (adjusted odds ratio [OR] 11.63, 95% confidence interval [CI] 10.04–13.47; P <0.001), electronic cardioversion (adjusted OR 2.41, 95% CI 1.65–3.51; P <0.001), and anti-arrhythmic drug use (adjusted OR 1.45, 95% CI 1.38–1.53; P <0.001). Conclusions::In hospitals participated in the CCC-AF project, >70% of AF patients were at a high risk of stroke. Although poor performance on guideline-recommended OAC use was found in this study, over time the CCC-AF project has made progress in stroke prevention in the Chinese AF population.Registration::ClinicalTrials.gov, NCT02309398.

Abstract OBJECTIVE To analyze the inflammation-related molecular targets of Pien Tze Huang in the treatment of hepatocellular carcinoma and to preliminary explore its mechanism. METHODS Obtain the ingredients and targets of Pien Tze Huang through TCMSP and BATMAN databases. Obtain the disease targets of hepatocellular carcinoma through Genecards, OMIM and TCGA databases. Take the intersection of compound targets and disease targets to get Pien Tze Huang’s target for the treatment of hepatocellular carcinoma. Obtain the related genes of inflammation pathway from the GSEA database, and then analyze the correlation between Pien Tze Huang’s therapeutic targets for hepatocellular carcinoma and inflammation-related genes to screen out inflammation-related targets, and explore the mechanism through GO and KEGG enrichment analysis. Then, single-factor cox analysis and LASSO regression were performed to construct related prognostic models. The 10 core targets were screened out through the protein-protein interaction(PPI) network. The model gene and the core target were intersected. The core compounds were screened out through the drug-compound-target network. Perform molecular docking verification between the core compound and the target. Construct a nomogram to assess the prognosis of patients. RESULTS Obtained 162 Pien Tze Huang targets, 522 hepatocellular carcinoma targets, 20 Pien Tze Huang therapeutic targets for hepatocellular carcinoma, and 16 inflammation-related targets. The enrichment analysis of GO and KEGG showed that their effects were mainly through biological functions such as monooxygenase activity, oxidoreductase activity, and chemical carcinogenesis-receptor activation. The ROC curve of the prognosis model calculated AUC as 0.780 in 1 year, 0.688 in 3 years, and 0.642 in 5 years, indicating that the model was reliable. The prognostic model intersects with the core target of PPI to get 5 targets: PON1, IGF2, NQO1, CCNB1 and IGFBP3. The nomogram was constructed using CCNB1, NQO1, and T staging, and its c-index was 0.726, indicating the reliability of the model. The drug-compound-target network suggested that quercetin was the core compound and targets the above two genes. CONCLUSION Pien Tze Huang’s treatment of hepatocellular carcinoma mainly uses quercetin to target CCNB1 and NQO1 to exert anti-inflammatory effects, and its prognostic model can be used to predict the survival of patients.

Abstract YU Fengbin was truly one of pioneers in school health field in modern China. His perspectives in school health was a preliminary attempt to solve school health problems in China by using the modern school health theory, and was also the product of idea combination.

Objective To study the impact of hepatitis B virus (HBV) infection on the activity of cord hematopoietic stem cells. Methods CD34+ cells were isolated from healthy human cord blood by miniMACS. Cells were cultured in IMDM complete culture medium containing stem cell factor (SCF),fms-like tyrosine kinase 3 ligand (FL), thrombopoietin (TPO), interleukin-3 (IL-3) and 10% fetal bovine serum. High copies HBV were added to the culture system. The proliferation of stem ceils and virus replication were observed. Following the proliferation, dendritic cells (DCs) were induced by adding granulocyte-macrophage colony-stimulating factor and IL-4. Morphous of stem cells and DCs were observed by microscope and the cell surface molecules were detected. Results The proliferation of stem cells infected with HBV was significantly lower than that of healthy stem cells (P＜0.01),and enhanced after adding cytokines (P＜0.01). At the same time, HBV replication was increased after adding cytokines in the culture system (P＜0.01), but the proliferation was still lower than that of healthy stem cells with cytokines in the culture medium (P＜0.05). Dane particles were found in the cytoplasma of stem cells infected with HBV by electron microscope. The expression of CD80,CD86 ,CD1a and HLA-DR on DCs derived from HBV infected stem cells were all lower than those on DCs from non-infected stem cells (P＜0.01). Conclusions HBV could infect CD34+ stem cell and the proliferation of the stem cell could enhance the virus replication. HBV could not only inhibit the proliferation of stem cells,but also down-regulate the immuno-phenotype expression of DCs derived from CD34+stem cells.
