ABSTRACT
Objective:To investigate the daily dietary fiber intake, the main adverse cardiovascular events during follow-up and the cardiac event-free survival in patients with chronic heart failure, and to analyze the relationship between dietary fiber intake and cardiac event-free survival in this population.Methods:This study was a prospective investigation. The investigation was performed in chronic heart failure patients from three third-class hospitals in Suzhou using general information questionnaire and 3-day diet diary. Major adverse cardiovascular events within 6 months after discharge and event-free survival were obtained by telephone call and medical records.Results:The incidence of major cardiovascular adverse events in 122 patients with heart failure was 27.9% within 6 months after discharge. Their dietary fiber intake was 8.1(5.8-10.9)g/d, lower than the recommended intake. Kaplan-Meier plots and log-rank tests demonstrated that cardiac event-free survival was significantly shorter in patients with dietary fiber deficiency ( P=0.043). Patients with dietary fiber intake ≥6 g/d after discharge showed decreased risk of major adverse cardiovascular events compared to patients with dietary fiber intake<6 g/d ( HR=0.422; 95% CI=0.189-0.942; P=0.035). Conclusions:This study revealed insufficient dietary fiber intake in patients with heart failure. Insufficient dietary fiber intake was associated with higher risk of major adverse cardiovascular events and shorter cardiac event-free survival in heart failure patients within 6 months after discharge. In conclusion, patients with heart failure can increase dietary fiber intake in order to improve prognosis.
ABSTRACT
Objective To translate and revise the Atrial Fibrillation-Quality of Life -18 (AF-QoL-18),and to test its reliability and validity. Methods The Chinese version of AF-QoL-18 was developed through the process of translation, back- translation, cultural adaptation, and preliminary experiment. A total of 187 atrial fibrillation (AF) patients in eight hospitals in Jiangsu province were investigated using the Chinese version to test the reliability and validity. Results Exploratory factor analysis identified three factors, including physiological, psychological and sexual dimensions, which could explain 65.055%of the total variance. The content validity index was 0.969. The Cronbach α coefficient was 0.915 and the retest reliability was 0.948 for the total scale. Conclusions The Chinese version AF-QoL-18 has proved to be reliable and valid.It can be used to measure the quality of life of AF patients in China.
ABSTRACT
With the rapid development of network technology,the data sharing and health research provides an efficient and convenient way for medical research and clinical guidance.In order to know patients' opinions on informed consent and data sharing,we investigated first-class hospitals in the coastal and inland areas with a total of 397 patients participating the questionnaire on clinical health and data sharing,reusing the remaining clinical blood samples in scientific researches,and the acceptance degree of broad consent investigation and related influencing factors.It was found that patients with strong consciousness of informed consent right tended to choose a simpler way of informed consent based on the analysis.Patients preferred social benefits than personal benefits with a strong spirit of dedication to the community.Medical institutions in China rarely applied broad consents and took relervant summative researhes,compared with the European and American countries' promotions at the national level.The research afforded the evidence,from most of patients' point of view to ethics committee in the review of such kind of studies to understand the public data sharing in privacy protection and broad consent of the individual opinion,in order to facilitate the rational development and promotion of health data sharing in China ethically.
ABSTRACT
Extensive informed consent is a special form of informed consent.In foreign countries,the applica-tion and implementation of extensive informed consent has enhanced the circulation rate of biological samples in fu-ture research and promoted the development of the clinical research of biological samples.But it also has caused some ethical issues because of weakening informed such as:obtaining the information about the subject not in time,the research risks unknown and quiting research not in time.At present,Europe and the United States have conducted a lot of research in the implementation conditions,informed content and framework,providing a strong support for the practice of extensive informed consent.The practice of extensive informed consent has become the development direction of the biological samples research in our country.The author compared the social environ-ment and theoretical research at home and abroad and thought that our country must practice and implement it on the basis of social recognition,the improvement of ethical review mechanism and legislative protection.

The IL28B gene belongs to a new interferon family λ and its genetic polymorphisms are identified to be associated with treatment effect and viral clearance. The purpose of this review is to discuss the role of the IL28B gene in treatment response and viral clearance of HBV-infected individuals, and further to reveal the mechanisms. This review could provide a theoretical basis for personalized medicines of HBV patients.
ABSTRACT
Objective To evaluate the efficacy of different duration of low-carbohydrate diet (LCD) intervention on glycosylated hemoglobin (HbA1c) in type 2 diabetes mellitus (T2DM) patients. Methods Randomized controlled trials (RCTs) of LCD intervention in T2DM patients were collected in the databases such as MEDLINE, PubMed, OVID, China National Knowledge Infrastructure, China Scientific Journal Database by VIP, Wanfang database, et al.Data were analyzed by RevMan 5.3 version. Results Eight RCTs were included. The results of Meta-analysis indicated that the effects of lowering HbA1c by LCD intervention for three (Z=2.28, P<0.05) and six months (Z=14.99, P<0.01) were better than other diabetes diets, but there was no significant statistical difference between one (Z=0.65, P=0.51) and two years (Z=1.62, P=0.10). Conclusions Hypoglycemic effect of short-term LCD was better than other diabetes diets, but long-term effect was similar between them. LCD was a therapeutic diet suitable for T2DM patients.
ABSTRACT
Objective To evaluate the efficacy of immediate and delayed postoperative removal of urethral catheters Methods Randomized controlled trials and quasi-experiment trails of immediate and delayed postoperative removal of urethral catheters were collected in the databases such as CENTRAL, PubMed, OVID, China National Knowledge Infrastructure (CNKI), China Biology Medicine disc (CBM), VIP, Wanfang Data, etc. Data were analyzed by RevMan 5.3 version.after heterogeneity analysis,pooled risk ratio (RR) with 95%confidence interval (95%CI) using both fixed and random effect models were estimated. Results Ten randomized controlled trials (RCTs) were included. The results of Meta-analysis indicated that immediate urinary catheter removal was associated with a lower incidence of urinary tract infections (RR=0.29, 95%CI 0.15 to 0.56, P=0.000 3), positive urinary culture (RR=0.31,95%CI 0.16 to 0.59, P=0.000 2) compared with the delayed removal group and seven studies recommended removal of the indwelling urinary catheter immediately after hysterectomy. While, there was a higher risk of re-catheterization (RR=4.56, 95%CI 2.93 to 7.08, P<0.01)in the immediate removal group. Seven studies recommended removal of the indwelling urinary catheter immediately after hysterectomy. Conclusions Removal of the indwelling urinary catheter immediately after hysterectomy was recommended.

Objective To investigate the effects of different cell cycles and their regulating genes on apoptosis of mononuclear-macrophages induced by Leptospira interrogans. Methods The diversity and alteration of cell cycles of murine mononuclear-macrophage line(J774A. 1 ) and human monocyte line(THP-1 ) before and after infected with L. interrogans serogroup Icterohaemorrhagiae serovar Lai strain Lai were detected using Cell Cycle Stain Kit plus flow cytometer. The cell cycle synchronized J774A. 1 and THP-1 cells were generated and then identified by using different cell cycle blocking agents and flow cytometer. By using Annexin V/PI Detection Kit combined with flow cytometer, the rates of early-apoptosis and late-apoptosis/necrosis in the synchronized and non-synchronized J774A. 1 and THP-1 cells after infection with L. interrogans strain Lai were determined. Several real-time fluorescence quantitative RT-PCRs were performed to the changes of mRNAs levels of p21, p27, p53, c-myc and cycA genes that associated with cell cycle and apoptosis in J774A. 1 and THP-1 cells before and after infected with L. interrogans strain Lai. Results There were G1, S and G2/M phases in both the non-infected normal J774A. 1 and THP-1 cells. On the contrast,the majority of infected J774A. 1 and THP-1 cells were stagnated at G1 phase, but the amount of S phase THP-1 cells was elevated while that of S phase J774A. 1 cells was not(P ＜0.05). No remarkable early-apoptosis in both the infected G1 phase J774A. 1 and THP-1 cells was found, whereas the rates of early-apoptosis and late-apoptosis/necrosis in the infected M phase J774A. 1 and THP-1 cells were significantly increased (P ＜0.05 ). Additionally, late-apoptosis / necrosis rate in the infected G1 phase THP-1 cells (P ＜ 0.05 )that not found in the infected G1 phase J774A. 1 cells. Compared to the non-infected cells, the p21 mRNA levels in the infected J774A. 1 and THP-1 cells were significantly elevated(P ＜0.05), and the c-myc and p27 mRNA levels in the infected J774A. 1 cells and the cycA mRNA level in the infected THP-1 cells were also higher than those in both the non-infected cells ( P ＜ 0.05 ). Conclusion Different cell cycles and their regulating genes have a role to affect the apoptosis of human and murine mononuclear-macrophages caused by L. interrogans with a diversity of cell line origins.
