Objective： To investigate the relationship between alanine aminotransferase （ALT） levels and metabolic syndrome （MS） in nonalcoholic fatty liver disease （NAFLD）. Methods： A total of 26527 subjects who received medical health checkup in our hospital from January 2005 to July 2007 were enrolled in the study. The diagnosis of fatty liver was based on ultrasound imaging. MS was defined according to the criteria of the Adult Treatment Panel III. ALT, triglyceride （TG）, high density lipoprotein cholesterol （HDL-c）, fasting plasma glucose （FPG）, height, weight, waist circumference （WC）, systolic blood pressure （SBP） and diastolic blood pressure （DBP） were measured in each subject to analyze the relationship between MS and ALT activity Results：（1） The prevalence of NAFLD in men （30.94%） was significantly higher than that in women （15.65%）; （2） The incidence of MS in NAFLD （33.83%） was significantly greater than that in non-NAFLD （10.62%）; （3） Of the 6470 subjects with NAFLD, in the age-adjusted partial correlation analysis, there were statistically significant correlations between the ALT levels and most metabolic risk factors in each sex （P〈0.01）, except that ALT levels multiple stepwise regression analysis, SBP lost its significance, and had no correlation with HDL-c in women. Moreover, in the WC, body mass index （BMI）, age, DBP, TG and FPG were independently associated with ALT levels in both sexes （P〈0.05）. HDL-c remained significant and was independently related to ALT levels in men; （4） ALT levels were significantly higher in subjects with MS compared to those without MS （P〈0.001）. Mean ALT levels increased with the number of MS components in each sex （P〈0.05 for trend）. Conclusion： We found a strong relationship between ALT levels and MS in NAFLD and revealed that the cluster of MS components might be the predictor for ALT elevations.

Journal of Zhejiang University-Science B(Biomedicine & Biotechnology) 2008年第1期9卷 34-38页

作者： Zhou-wen chen li-zheng fang li-ying chen Hong-lei DAI Department of General Practice Sir Run Run Shaw Hospital School of Medicine Zhejiang University Hangzhou 310016 China

Objective: To compare the efficacy of a short messaging service (SMS) text messaging and phone reminder to im-prove attendance rates at a health promotion center. Methods: A total of 1 859 participants who had scheduled appointments in the health promotion center of our hospital from April 2007 to May 2007 were enrolled in the study and randomly assigned into 3 groups: control (no reminder) group,SMS text messaging reminder group and telephone reminder group. Attendance rates and costs of interventions were collected. Results: A total of 1848 participants were eligible for analysis. Attendance rates of control,SMS and telephone groups were 80.5%,87.5% and 88.3%,respectively. The attendance rates were significantly higher in SMS and telephone groups than that in the control group,with odds ratio 1.698,95% confidence interval 1.224 to 2.316,P=0.001 in the SMS group,and odds ratio 1.829,95% confidence interval 1.333 to 2.509,P<0.001 in the telephone group. However,there was no difference between the SMS group and the telephone group (P=0.670). The cost effectiveness analysis showed that the cost per attendance for the SMS group (0.31 Yuan) was significantly lower than that for the telephone group (0.48 Yuan). Conclusion: SMS and telephone are effective reminders for improving attendance rate at a health promotion center. SMS reminder may be more cost-effective compared with the telephone reminder.

EXPERIMENTAL STUDY OF EFFECTS OF AIR CONTENT ON CAVITATION AND PRESSURE FLUCTUATIONS

引用

Journal of Hydrodynamics 2010年第5期22卷 634-638页

作者： YE Jin-ming XIONG Ying li fang chen Shuang-qiao College of Naval Architecture and Power Naval University of Engineering Wuhan 430033 China

This article studies the effects of air content on propeller cavitation and pressure fluctuations. The cavitation is observed while the pressure fluctuations on the hull are measured. When adjusting the air content, the sheet cavitation range does not change distinctly, but the pressure fluctuations see obvious differences. The amplitudes of the pressure fluctuations increase with the decrease of the air content. The results indicate that the air content has little effect on the sheet cavitation range but has an important effect on the bubble cavitation and the tip vortex cavitation. When the air content decreases, the water tensile force increases, which results in the instability of the bubble cavitation and the tip vortex cavitation and the increase of the pressure fluctuations. To minimize the scale effects, the experiments should be run at a high Reynolds number with a high nuclei content. The high Reynolds number is often realized by increasing the flow velocity and the propeller rotation speed, and the high nuclei content is often made by increasing the dissolved air content.

引用

Agricultural Sciences in China 2011年第1期10卷 120-125页

作者： JIANG Zong-yong ZHOU Gui-lian liN Ying-cai JIANG Shou-qun ZHENG Chun-tian HAN li-ming chen fang Key Laboratory of Animal Nutrition and Feed Science （South China） Ministry of Agriculture/Institute of Animal Science Guangdong Academy of Agricultural Science Guangzhou 510640 P.R.China

A synthetic isoflavone （ISO-S） or genistein was added in culture medium at different concentrations （0, 10, 20, 30, 40, and 80 *** L^-1） to investigate the effects of soybean isoflavones on antioxidative capacity of porcine skeletal muscle satellite cells. After 48 h incubation, the suspension was cryopreserved for the determination of superoxide dismutase （SOD）, catalase （CAT）, glutathione peroxidase （GSH-Px） activities, and malondialdehyde （MDA） content. The mRNA levels of SOD, CAT, and GSH-Px gene in cells were detected with Taqman fluorescent probe method. The results showed that the content of MDA and the activities and the mRNA levels of SOD of porcine skeletal muscle satellite cells were influenced by supplemented soybean isoflavone （P〈0.05） when adding 10-80 μmol L^-1 ISO-S or genistein in the medium. The MDA contents, SOD and CAT activities and their mRNA expression levels of porcine skeletal muscle cells responded quadratically （P〈 0.05） as the level of ISO-S or genistein increased. Pre-incubation of porcine skeletal muscle satellite cells with ISO-S or genistein at 10-40 pmol L-1 elevated the activities and the mRNA expression levels of SOD and CAT in cells concurrently and decreased the cellular content of MDA （P〈 0.05）. The results indicated that pre-incubation of ISO-S or genistein at 10- 40μmol L^-1 could improve the antioxidative capacity of porcine skeletal muscle satellite cells.

Chinese Medical Journal 2013年第22期126卷 4210-4215页

作者： CAO cheng-fu REN Jing-yi ZHOU Xiang-hai li Su-fang chen Hong Department of Endocrinology (Zhou XH) Peking University People's Hospital Beijing 100044 China

Background Hypertension, diabetes mellitus, hypercholesterolaemia and current smoking are the strongest modifiable cardiovascular risk factors for acute myocardial infarction （AMI）. We examined their changing trends over the last 20 years. Methods The clinical data of 3498 patients hospitalized in Peking University People＇s Hospital with AMI from 1991 to 2010 were used. Information was collected regarding to patients＇ demographic data, cardiovascular risk factors （hypertension, diabetes mellitus, hypercholesterolemia and current smoking）. To assess trends over time in the prevalence of risk factors, we categorized patients into four groups （1991 to 1995, 1996 to 2000, 2001 to 2005 and 2006 to 2010）. Results Highly significant increases were observed in the prevalence of hypertension from 40.8% to 55.6% for males and from 58.0% to 69.0% for females; and diabetes mellitus from 12.9% to 30.8% for males and from 23.0% to 42.3% for females. Similarly, the prevalence of hypercholesterolaemia decreased from 53.1% to 30.7% for males and from 57.0% to 44.0% for females. The prevalence of current smoking decreased in females from 29.0% to 11.1%, but remained unchanged in males. In addition, the proportion of patients with more than three modifiable risk factors increased from 19.0% to 27.1% and the age at onset of AMI extended to younger as well as older individuals. Conclusions The prevalence of hypertension and diabetes mellitus are still increasing in patients with AMI in Beijing and although the prevalence of hypercholesterolaemia and current smoking decreased, high clustering of risk factors were commonly present. These adverse trends show a compelling need for more effective management of cardiovascular risk factors.
