Multiple etiological factors are integrally involved in the development of hepatitis B virus (HBV)infection.Interleukin-10 (IL-10)is an essential cytokine of immune regulation,and IL-10 gene promoter polymorphism affects its mRNA transcription and serum level. IL-10 is related to the prognosis of HBV infection.This review briefly discusses the association of IL-10 gene polymorphism and its serum level with the prognosis of HBV infection,and summarizes the role of IL-10,as an anti-inflammatory cytokine,in host immune function, the prognosis and progression of HBV infection,and HBV-related complications.IL-10 gene polymorphism and its serum level are closely associated with inflammatory response after HBV infection,influence HBV clearance,and are related to the severity of HBV-related liver injury,liver cirrhosis,and hepatocellular carcinoma.The determination of IL-10 gene and serum levels may provide a predictive marker for the prognosis of HBV infection.

Objective To investigate the application of colostomy care products in managing the leakage around PTCD drainage tube, and to discuss its clinical effect. Methods A total of 56 patients with malignant obstructive jaundice, who had received PTCD and suffered from postoperative leakage around PTCD drainage tube, were randomly and equally divided into the study group (n=28) and the control group (n=28). The colostomy care powder, the skin protective film and the colostomy bag were used for the patients of the study group, while iodophors, sterile gauze and mupirocin ointment were employed for the patients of the control group. The incidence of irritant dermatitis around PTCD drainage tube, the degree of comfort to the indwelling tube judged by the patient, and the nursing workload for PTCD drainage tube were determined, and the results were compared between the two groups. Results The incidence of irritant dermatitis around PTCD drainage tube in the study group was obviously lower than that in the control group. And the degree of comfort to the indwelling tube judged by the patient in the study group was much higher than that in the control group. The differences between the two groups were statistically significant (P<0.05). Conclusion Combination use of colostomy care powder, skin protective film and colostomy bag can effectively reduce the incidence of irritant dermatitis around PTCD drainage tube and improve the patient’s condition. Therefore, this method is worthy of popularization in clinical practice.

The standardized management strategy is put into practice of hospital logistics. The standard time management as used in sample delivery service, is cited as an example for analysis of the rationality and efficiency of standard operating practice in hospital logistic services. The purpose is to identify causes of lost operation time and the countermeasures,thus improving working efficiency,performance-based management method,and scoring better operating performance and standard operation process reengineering.

Objective:To quantitatively evaluate myocardial microcirculation perfusion changes after percutaneous intracardiac septal radiofrequency ablation (PIMSRA, Liwen procedure) in patients with obstructive hypertrophic cardiomyopathy (HOCM) using myocardial contrast echocardiography (MCE) and to further establish the effect of the procedure and predict the long-term prognosis of patients.Methods:A total of 45 patients with HOCM treated by the Liwen procedure in the First Affiliated Hospital of Air Force Medical University (Xijing Hospital) from July 2019 to June 2020 were included. MCE was performed before and 6 months after surgery, respectively. Time-intensity perfusion curve analysis was performed using QLab 10.8 offline software to obtain quantitative parameters of myocardial microcirculation perfusion including myocardial blood volume (A value), myocardial blood flow velocity (β value), and myocardial blood flow (A×β value), then the changes in parameters before and after the procedure were compared.Results:After the Liwen procedure, the mean septal thickness and mean left ventricular free wall thickness were significantly reduced, accompanied by a significant reduction in the left ventricular outflow tract pressure gradient (LVOT-PG) and mitral regurgitation length, and a significant improvement in mitral systolic antegrade motion (SAM) (all P<0.001). In addition, the left ventricular ejection fraction (LVEF) did not deteriorate significantly ( P=0.560) and the E/e′ ratio decreased after the procedure ( P=0.015). Besides, the A values of both the ventricular septum and the left ventricular free wall were not significantly changed compared to those before procedure ( P>0.05), whereas the β values and A×β values were obviously increased ( P<0.05). Conclusions:Myocardial blood velocity and myocardial blood flow in the septum and left ventricular free wall were significantly increased in patients with HOCM after the Liwen procedure, suggesting a significant improvement in myocardial microcirculation perfusion. MCE provides a non-invasive quantitative evaluation parameters of myocardial microcirculation perfusion for the Liwen procedure for the treatment of HOCM.

Objective: Previous cross-sectional studies suggested that elevated levels of total cholesterol content of erythrocyte membrane (CEM) could significantly increase the risk of acute coronary syndrome (ACS). The purpose of the present study was to assess the predictive value of baseline CEM levels for the risk of clinical endpoint events in patients with ACS through prospective follow-up studies. Methods: This study is a prospective follow-up study, which consisted of 859 patients with first ACS (698 patients with unstable angina pectoris and 161 patients with acute myocardial infarction), diagnosed and hospitalized in the First and Second Affiliated Hospital of Anhui Medical University. The routine blood lipid levels and CEM were measured. Patients were divided into two groups according to the median of baseline CEM: CEM≤131.56 μg/mg group (n=430) and CEM>131.56 μg/mg group (n=429). Patients were followed up at 6 months interval. The clinical endpoints were nonfatal myocardial infarction, nonfatal stroke, all-cause mortality, all-cause mortality, heart failure requiring hospitalization, and coronary artery revascularization. Kaplan-Meier curve analysis and Cox proportional hazard model were used to analyze the impact of elevated CEM on the occurrence of clinical end-point events. HR values and 95%CI of each variable were obtained. Cox regression analysis of all-cause mortality was performed according to whether patients had risk factors for coronary heart disease (hypertension, diabetes, smoking and elevated LDL-C) and whether they were treated with PCI. Results: The follow-up time was 1 640 (1 380, 2 189) days. Cox analysis after adjustment showed that an elevated baseline of CEM (>131.56 μg/mg) was associated with an increased risk of all-cause mortality (HR=1.690, 95%CI 1.041-2.742, P=0.034), but had no significant predictive effect on the other clinical endpoints. Subgroup analysis showed that elevated baseline CEM levels in ACS patients with LDL-C>1.8 mmol/L (HR=1.687, 95%CI 1.026-2.774, P=0.039), receiving in-hospital PCI (HR=2.365, 95%CI 1.054-5.307, P=0.037), or male (HR=1.794, 95%CI 1.010-3.186, P=0.046) were associated with an increased risk of all-cause mortality. Conclusion The results showed that elevated CEM levels can increase the risk of all-cause mortality in ACS patients.
