Hepatitis B virus (HBV) infection causes pathological changes of the liver,including liver inflammation,hepatocyte necrosis,and even liver fibrosis,and promotes the progression from chronic hepatitis to liver cirrhosis and liver cancer,but related mechanisms remain unclear.The mechanism for the interaction between hepatocytes infected by HBV and uninfected hepatocytes/host immune system might be exosomes-mediated cell-cell communication in liver microenvironment.Many studies have demonstrated that viral infection can regulate the production of exosomes and affect their composition,and viral microRNAs,proteins,and even the entire virion can be incorporated into the exosomes,which can affect the immune recognition of viruses or regulate the function of adjacent cells.This article elaborates on the production and composition of exosomes and their roles in viral infection,as well as the research advances in the association between exosomes and HBV infection.

Five patients with mediastinal bronchogenic cyst (MBC) were treated with endoscopic submucosal tunnel dissection (ESTD) between January 2018 and October 2019 at the Department of Gastroenterology in Henan Provincial People′s Hospital. Lesions were located in the middle or lower esophageal level, with diameters≤3.5 cm. The tunnel establishment time was 13-18 min, and the tumor stripping time was 30-51 min. The number of titanium clips used for tunnel closure was 5-8. The tumors were completely resected. No major bleeding or hypoxemia occurred during the operation and no serious adverse reactions occurred after the operation. Postoperative pain scores were all ≤3. The hospital stay was 4-7 days. There was no tumor residue and recurrence during 4-23 months of follow-up.It is suggested that ESTD for MBC which derived from post mediastinum and located at the lower or middle level esophagus is safe and effective.

Objective To detect the expression levels of the miR-205 in lung cancer tissue and A549 cells and its targeted gene YES1 using qRT-PCR and dual fluorescence protein repoter assay system,and to explore the possible mechanism of miR-205 to inhibit the proliferation of lung cancer A549 cells.Methods The expression levels of miR-205 in 10 cases of lung cancer tissue and adjacent normal lung tissue were detected with qRT-PCR.The cell growth curve and colony formation assay were used to determine the proliferation rate of A549 cells after transfected by miR-205 mimics and control mimics.The sequences of YES1 3′UTR (untranslated region)and mutation target sites of YES1 3′UTR were inserted into the plasmid which expressed green fluorescence protein (pcDNA3/EGFP) respectively to construct the green fluorescence protein plasmids of YES1-3′UTR and mut-YES1-3′UTR. There were six groups in the study:YES1-3′UTR, YES1-3′UTR and miR-205 mimics, YES1-3′UTR and control mimics,mut-YES1-3′UTR, mut-YES1-3′UTR and miR-205 mimics, mut-YES1-3′UTR and control mimics;after the plasmids expressed red fluorescent protein (pDsRed2-N1 )were cotransfected into A549 cells,the extracted protein was detected with fluorescence spectrophotometer.Results Compared with adjacent normal lung tissue,the expression levels of miR-205 in lung cancer tissue and A549 cells were decreased (P<0.05 );the proliferation rate of A549 cells in miR-205 mimics group was lower than that in control mimics group (P<0.05). The fluorescence protein expression level in YES1-3′UTR and miR-205 mimics co-transfected group was lower than that in YES1-3′UTR and control mimics co-transfected group, the difference was statistically significant (P<0.01).The number of cell colony formation of A549 cells in highly expressed YES1 group was higher than that in cell control group (P<0.05).Conclusion MiR-205 may inhibit the proliferation of A549 cells through regulating of the expression of YES1 directly.miR-205 and YES1 are potential therapeutic targets for the biological treatment of tumor.

Objective: To assess the trends in clinical characteristics and treatments for in-hospital patients with ST-segment elevation myocardial infarction (STEMI) in western rural China from 2001 to 2011. Methods: A two-stage random sampling procedure was used in our study. In 1st stage, stratiifed random sampling was applied to identify the participating hospitals and in 2nd stage, random sampling was applied to determine the patients to be studied. Taking 2001, 2006 and 2011 as 3 time points to study the in-hospital records for STEMI treatments. The results in each year were analyzed by weighted calculation in order to adjust the proportional impact by different sampling and therefore, to relfect the entire condition in western rural area. Results: A total of 32/35 hospitals with 1028 STEMI records were enrolled. From 2001 to 2011, the admitted STEMI patients from 64 (54-70) years of age increased to 67 (56-75) years,Ptrend<0.05, while gender composition was similar, the risk factors for cardiovascular disease such as hypertension, dyslipidemia and smoking substantially increased. Among patients without contraindications, the ues of following medications increased from 2001 to 2011: aspirin from 73.6% to 89.9%, clopidogrel from 0% to 66.5%, β-blockers from 25.4% to 64.3% and statins from 7.5% to 89.8%, allPtrend<0.01. From 2001 to 2011, the rates of primary PCI application were from 0% to 0.3%,Ptrend=0.51, the rates of thrombolytic therapy increased from 33.4% to 55.4%,Ptrend<0.01. At the year of 2001, 2006 and 2011, the reperfusion rates were 33.4%, 50.7% and 55.4%, Ptrend<0.01; the mortality within 7 days of admission were 3.0%, 10.1% and 6.7%, the rates of death or treatment withdrawal because of terminal status were 5.3%, 12.3% and 10.9%, there was no signiifcant trend in the above 2 rates after adjustments. Conclusion: The quality of medical care for STEMI was signiifcantly improved in western rural China from 2001 to 2011, while there are still gaps between western rural area and other regions.

Objective: To assess the trends of clinical characteristics, diagnostic and treatment conditions and outcomes for in-hospital patients with ST-segment elevation myocardial infarction (STEMI) in eastern rural China from 2001 to 2011.
Methods: Through a two-stage random sampling, a representative in-hospital STEMI patient group in eastern rural China of 2001, 2006 and 2011 were enrolled. In 1st step, a simple random-sampling procedure was conducted to identify the collaborating hospitals and in 2nd step, a systematic sampling procedure was performed to select representative patients from those admitted to each collaborating hospital for STEMI during the study period. Then we obtained patients’ clinical information from their medical records. Finally, we weighted the ifndings for each year to represent the overall situation.
Results: A total of 2820 STEMI medical records from 32 collaborating hospitals were enrolled. From 2001 to 2011, the median age of STEMI patients increased from 66 to 68 years, P<0.01, the percentage of female patients elevated from 31.4%to 35.8%, P<0.05. The ratios of cardiovascular risk factors were gradually increased. Among the patients without documented contraindications, application of percutaneous coronary intervention (PCI) increased from 0%to 27.5%, P<0.01, reperfusion increased from 49.7%to 58.8%, P<0.01. Administration of aspirin elevated form 80%to 87.8%, Clopidogrel from 0%to 72.6%, statins from 16.7%to 89.6%;administration ofβ-blockers within 24 h of admission elevated from 41.5%to 55.5%, P<0.05 and ACEI/ARB from 58.3%to 69%, P<0.01. In 2001, 2006 and 2011, the in-hospital mortality within 7 days were 6.8%, 8.3%and 5.7%respectively;mortality plus treatment withdrawal because of terminal status at discharge were 10.2%, 12.4%and 9.5%respectively. After adjustment, the above ratios did not change signiifcantly.
Conclusion: From 2001 to 2011, application of PCI grew from nothing and effective medication was improved for in-hospital STEMI patients in eastern rural China. However, there were still obvious gaps for diagnosis and treatment from the guideline requirement;the patient outcomes have not been improved.
