Objective To explore the correlation between hyperuricaemia and blood pressure, and blood lipid and glucose. Methods By using simple cluster sampling, 2 branch units from PetroChina Changqing Oilfield Company were selected, and all the 720 subjects with hyperuricaemia (HUA) were assigned to the HUA group; another 620 participants with normal uric acid (UA) level into the normal group. The correlation between blood uric acid and blood pressure,and blood lipid and glucose was assessed by Logistic regression. Results The odds ratio (OR) of those who had 1,2 or 3 abnormal status of hypertension,hyperlipidemia and impaired fasting glucose in the HUA group were much higher than the normal group (OR values were 4. 036,2. 562, and 4. 174, respectively). Logistic regression showed that male, systolic blood pressure ( SBP), GLU, total cholesterol ( TC), triglyceride ( TG), low-density lipoprotein cholesterol (LDL-C) were risk factors of H UA ( OR values were 7. 736,2. 309,1.721,2. 761 and 1. 411,respectively) ,while high-density lipoprotein cholesterol (HDL-C, OR = 0. 211 ) was a protective factor of HUA. Conclusions Gender,blood pressure and blood lipid may have correlation with blood UA. Multiple risk factors should be considered to improve the effectiveness of health education and health promotion.

OBJECTIVELong time exhaled oxygen will induced oxygen toxicity. Some studies had found that different pathology may exised in normobaric and hyperbaric pulmonary oxygen toxicity, and nitric oxide synthase (NOS) may play a role. In this study, we discussed the change of NOS in normobaric and hyperbaric pulmonary oxygen toxicity.

METHODSSixty male SD rats were randomly divided into 6 groups (n = 10), exposed to 1 ATA (atmosphere absolute), 1.5 ATA, 2 ATA, 2.5 ATA and 3 ATA, 100% oxygen for 56, 20, 10, 8, 6 hours respectively. Rats were exposed to air as control. After exposure, the protein in bronchoalveolar lavage fluid (BALF), the wet/dry weight of lung and the expression of eNOS, nNOS in lung were defined.

RESULTSAs compared to air group, the protein in BALF, the wet/dry of lung were significantly elevated in 1.0 ATA group, while these changes were not so obviously in the other groups, and these changes in hyperbaric oxygen group (approximately 1.0 ATA) were significantly decreased as compared with nonnrmobaric oxygen group (1.0 ATA). The expression of nNOS were not changed in normobaric and hyperbaric pulmonary oxygen toxicity, while the expression of eNOS was significantly decreased in 2 ATA group, and significantly elevated in 2.5 ATA and 3 ATA group.

CONCLUSIONThe expression of eNOS can change when exposed to different pressures of oxygen.

OBJECTIVETo describe the prevalence of behavior on diet, physical activities and body mass index (BMI) in different populations related to factors as education, occupation and geographical distribution.

METHODSIndicators including frequency of taking different foods, intake of cooking oil/fast foods, intensities of physical activities at work, proportion of taking physical exercises during the day, sedentary life style and BMI were calculated based on results from 17 questions of behavior risk factors surveillance (BRFS) questionnaire by weight on age structures from 2000 census.

RESULTSSeventy percentage of the people took vegetable and 40 percent took fruits 5-7 days per week, and over 50 percent of them ate pork/beef/mutton but few of them ate beans and eggs. 25 percent of the people ate chicken/duck/fish/and shrimps 5-7 times per week but another 40 percent ate them only less then once per week. 70% of the people almost never drank milk or milk-products. 15 percent of them consumed sweet and greasy foods 3-7 days per week and 30 percent of them ate smoked food 3-7 days per week in the past 30 days. The proportions of food intake were different under different geographical regions, education levels and occupations. 11.7% of the sample population cooked mainly with animal oil, and 33% of the students had ever been to McDonald's. 11.7%, 20.5%, 44.7% and 23.0% of the subjects engaged in sedentary, light, moderate or heavy physical activities respectively. 18.04% of the subjects took part in physical exercises with different proportions by gender, occupation, education and geographical settings. 8.3% people were slim which was defined as having BMI lower than 18.5 kg/m(2). 68.0% of the people had a BMI as 18.5-23.9 kg/m(2). 23.7% of the subjects were being overweight which was defined as having BMI greater than 24 kg/m(2), among which 8.5% people with a BMI of 24-24.9 kg/m(2).

CONCLUSIONThe prevalence of overweight and obesity will increase in the next 20-30 years, with the habits of taking more foods with high fat and energy but with less physical activities and keeping the idea as "fattier makes happier". Priorities should be given to changing the diet habit, avoiding over-intake of high fat and high energy plus increasing physical activities through publicity of knowledge on health, policy enforcement and development of supportive environment.

OBJECTIVETo describe the prevalence of injury associated health risk factors, especially traffic accident/suicide-associated health risk factors in different populations by education, occupation and districts.

METHODSThe indicators on traffic peccancy behavior and protective measures, storage of pesticide and micecide were calculated based on results from 13 questions of BRFS questionnaire by weight on age structures from 2000 census.

RESULTS36.7% pedestrians reported that they had traffic peccancy behavior in the past 30 days with 3.67% as always, 11.3% as sometimes and 21.7% as seldom. 30.3% bicycle riders reported that they had traffic peccancy behavior in the past 30 days. There were 13.2%, 11.4% and 16.9% auto-drivers reported ever having drunken driving, tired driving or driving without license. 7.7% drivers and riders always wore a safety belt. 19.1% motorcycle drivers and riders reported that they wore a crash helmet while riding. The traffic peccancy behavior in males, in rural area was more serious than in females and in urban areas. There were more families preserving pesticide and micecide in rural than in urban areas. 10% of these families did not have a good storage.

CONCLUSIONThe traffic peccancy behavior was very serious, but the protective measures were not well conducted in China. The storage of pesticide and micecide was unsatifactory. The awareness on safety was insufficient in the general population, suggesting that it is of urgent importance to change people's improper behaviors through health education. It is also important to develop regulations to create supportive environment in reducing the deaths caused by injury.

OBJECTIVETo describe knowledge, attitudes and behaviors on infectious diseases in different Chinese populations by their education levels, occupation and residential districts.

METHODSData regarding awareness of the transmission routes and prevention strategies on hepatitis, sexually transmitted diseases (STD), acquired immune deficiency syndrome (AIDS) and prevalence rates on a) self-reported STD b) seeking treatment for STD c) source of knowledge on AIDS prevention, were calculated based on results from 17 questions of BRFS questionnaire by weight on age structures from 2000 census.

RESULTSMost people realized that hepatitis, STD and AIDS were important issues in public health. However, their awareness on the transmission routes of these diseases was not satisfied. Moreover, due to the fear of these diseases, 27.6% and 30.1% of the people studied thought that shaking hands with STD patients and HIV carriers could get infected. 9.9% of the people reported that they ever used a condom during the past year. 2.2/1000 of the people reported that they had ever suffered from STD during the past 5 years, with 3.4/1000 in males, 0.9/1000 in females, 4.2/1000 in urban population and 1.6/1000 in rural population. Among these STD patients, 75.0% of them reported that they had ever received treatment in a STD clinic including 38.2% of them reporting that they had ever received treatment in private clinics without license, and 6.7% of them reported that they had ever treated by drugs bought by themselves. 47.0% of people reported that they had received health education materials or information on AIDS prevention from medical workers or through media. 12.1% of the people had been informed that condom use could prevent from STD and AIDS transmission.

CONCLUSIONThe awareness on hepatitis, STD and AIDS was quite insufficient in the Chinese general population, especially in rural and western part of China. With the development of AIDS epidemic from people with high risk behavior to the general population, China will undertake tremendous disease burdens from AIDS in the future.
