<b>Objective:b> To analyze the prevalence and co-prevalence of cardio metabolic (CM) risk factors in adults in China. <b>Methods:b> The project data of 2015 Nutritional Status and Health Transition of Chinese Residents were used, and 5 456 adults aged 18-59 years with complete socio-demographic, anthropometric, and blood biochemical data were selected as the study subjects. The definition released by the International Diabetes Federation in 2005 were used to define each CM risk factors, including central obesity, elevated TG, reduced HDL-C, elevated blood pressure and elevated FPG. The co-prevalence of the risk factors was defined as adults having ≥2 risk factors. Multivariable logistic regression analysis was performed to evaluate the relationship between CM risk and socio-demographic factors. <b>Results:b> About 80.8% of adults had at least 1 risk factor, and 54.0% had co-prevalence of risk factors. Gender, age, education level and living area were significantly associated with the prevalence of major metabolic risk factors. After adjusting for other factors, compared with men, women were more likely to have central obesity and reduced HDL-C, but not more likely to have elevated blood pressure, elevated FPG and elevated TG (P<0.01). Compared with adults aged 18-44 years, adults aged 45-59 years were more likely to have central obesity, elevated blood pressure, elevated FPG and elevated TG (P<0.01). The odds of having central obesity, elevated blood pressure and elevated fasting plasma glucose in the adults in eastern China were significantly higher than those in the central and western China. <b>Conclusions:b> In 2015, less than 20% of the adults aged 18-59 years in China had no cardio metabolic risk factors, and more than half of them had two or more risk factors. Gender, age and living areas were the major influencing factors. It is necessary to take effective intervention measures targeting adults at high-risk for the early prevention of cardiovascular disease.

Background & Objective: No clinical study of any interferon beta therapy has yet been successfully conducted in Chinese multiple sclerosis patients, probably due to the low incidence of this disease in China. The primary objective of this study was to demonstrate that treating multiple sclerosis patients of Chinese origin with interferon beta-1b has a beneficial effect on disease course, as measured by the decrease of newly active lesions on magnetic resonance imaging. Methods: Chinese patients diagnosed with relapsing-remitting or secondary-progressive multiple sclerosis were enrolled in this multicenter, open label, single-arm study. Following a 3-month pre-treatment phase, patients were treated with 250 µg interferon beta-1b subcutaneously every other day for 6 months. Patients had regular assessments for treatment safety and efficacy of the treatment. Results: Thirty seven patients completed the trial. Significant decreases in the number of newly active lesions were observed in the 6-month treatment period compared with the pre-treatment period (median decrease 1.5 lesions, p<0.001). Most adverse events were mild and transient and no serious ones were observed. Conclusions: Treatment with interferon beta-1b significantly reduced the occurrence of new lesions and was well tolerated in this Chinese population. These findings support the use of interferon beta- 1b for treating Chinese MS patients.

<b>Objective:b> To investigate the infection pattern and etiological characteristics of a case of human infection with highly pathogenic avian influenza A (H7N9) virus and provide evidence for the prevention and control of human infection with highly pathogenic avian influenza virus. <b>Methods:b> Epidemiological investigation was conducted to explore the case's exposure history, infection route and disease progression. Samples collected from the patient, environments and poultry were tested by using real time reverse transcriptase-polymerase chain reaction (RT-PCR). Virus isolation, genome sequencing and phylogenetic analysis were conducted for positive samples. <b>Results:b> The case had no live poultry contact history, but had a history of pulled chicken processing without taking protection measure in an unventilated kitchen before the onset. Samples collected from the patient's lower respiratory tract, the remaining frozen chicken meat and the live poultry market were all influenza A (H7N9) virus positive. The isolated viruses from these positive samples were highly homogenous. An insertion which lead to the addition of multiple basic amino acid residues (PEVPKRKRTAR/GL) was found at the HA cleavage site, suggesting that this virus might be highly pathogenic. <b>Conclusions:b> Live poultry processing without protection measure is an important infection mode of "poultry to human" transmission of avian influenza viruses. Due to the limitation of protection measures in live poultry markets in Guangzhou, it is necessary to promote the standardized large scale poultry farming, the complete restriction of live poultry sales and centralized poultry slaughtering as well as ice fresh sale.

<b>OBJECTIVESb>To perform GIS spatial analysis on malaria transmission patterns in Jiangsu after setting up a malaria database and developing GIS model of malaria transmission in Jiangsu province.

<b>METHODSb>The epidemiological GIS database of malaria in Jiangsu province was established using ArcView 3.0a software. The climate data covering Jiangsu province and its peripheral area were extracted from the FAOCLIM database, the total growing degree days (TGDD) for Plasmodium vivax were calculated, and spatial distribution for TGDD was analyzed by ArcVeiw 3.0a.

<b>RESULTSb>The predicted malaria distribution map based on TGDD was created, which showed that the transmission of malaria decreased gradually from west to east, which can be divided into three belts according to the degree of transmission. The 14-year mean morbidity distribution map of malaria in Jiangsu showed that the middle and west parts of Jiangsu is the most serious endemic area. The morbidity in the areas along the Taihu valley, such as Suzhou, Wuxi and Changzhou, as well as Nantong and a few of northern counties are the lowest. The morbidity of other places is at the middle level. The 14-year mean morbidity distribution map of malaria is correlated with predicted malaria distribution map for TGDD.

<b>CONCLUSIONb>It is possible to monitor the malaria transmission by GIS predicted model based on TGDD.

Non-steady state noise has become the main type of workplace noise. Compared with steady state noise, non-steady state noise may cause more serious hearing loss. This paper reviews the new situation of occupational hearing loss caused by non-steady state noise exposure, the overview of international noise exposure assessment standards and new challenges, and the new evidence of non-steady state noise induced hearing loss, so as to provide the basis for the future research of non-steady state noise induced hearing loss.

<b>Objective:b> Smoking is the most important risk factor for COPD. Understanding the smoking rate, current smoking rate, average age to start smoking and average daily consumption of cigarettes among people aged ≥40 years in China can provide scientific evidence for the effective control and prevention of COPD. <b>Methods:b> Data were from COPD surveillance in China (2014 to 2015) which covered 31 provinces, autonomous regions and municipalities. A total of 75 107 adults aged ≥40 years selected through multi-stage stratified cluster sampling from 125 surveillance sites (county/district) were surveyed by electronic questionnaire during face to face interviews. The smoking rate and other smoking index were estimated by using weighting complex sampling design. <b>Results:b> The smoking rate and current smoking rate were 40.0% (95%CI: 38.5%-42.0%) and 31.0% (95%CI: 29.7%-32.0%), respectively, among the Chinese aged ≥40 years in 2014. The smoking rate and current smoking rate in males (74.1% and 57.6%) were much higher than those in females (5.4% and 4.0%). And the two rates were significantly higher in rural area (41.2% and 32.4%) than in urban area (38.8% and 29.5%). The mean age of smokers to start smoking was 20.1 (95%CI: 19.7-20.5) years. The younger the smokers were, the earlier their average age to start smoking was (The ages to start smoking for smokers aged 40-, 50-, 60-, ≥70 years were 18.3, 19.2, 20.9 and 23.1 years, respectively). Average daily cigarette consumption of current daily smokers was 18.9 (95%CI: 18.1-19.7) cigarettes, and the daily cigarette consumption was higher in males (19.3 cigarettes) than in females (12.5 cigarettes). <b>Conclusion:b> The smoking rate in males aged ≥40 years is high in China. Compared with urban area, the smoking rate in rural area is higher, posing a big challenge for COPD control and prevention.

<b>Objective:b> To describe and analyze the passive smoking exposure level in adults aged ≥40 years in China. <b>Methods:b> A total of 75 107 adults from 125 sites of COPD surveillance points in China were surveyed by electronic questionnaire during face to face interviews. After comprehensive weighting of the samples, the passive smoking exposure level was analyzed. <b>Results:b> The passive smoking exposure rate of the adults aged ≥40 years was 44.9% (95%CI: 42.3%-47.5%). The exposure rate was highest in those aged from 40 to 49 years (51.0%, 95%CI: 47.9%-54.1%) in term of age groups, in those with senior high school education level and above (48.6%, 95%CI: 44.9%-52.2%) in term of education level, and in office workers (57.7%, 95%CI: 51.8%-63.7%) in term of occupation. The adults reporting passive smoking exposure every days in a week accounted for 27.7% (95%CI: 25.5%-29.8%), and those reporting household passive smoking exposure accounted for 28.3% (95%CI: 26.2%-30.5%). Logistic regression analysis showed that the passive smoking exposure level was different in different age groups and occupation groups. <b>Conclusion:b> The passive smoking exposure level is still high in adults in China. Age and occupation are the influencing factors of passive smoking exposure level.
