Results 18 cases of renal duplication were diagnosed by CTU,confirmed by operation.3 of 11 were detected on IVU,and 1 of 4 on MRU.The diagnosis rate of CTU in renal duplication has been 100%,higher than IVU and MRU. Conclusions CTU is a reliable and optimal technique for the diagnosis of renal duplication.

Objective To assess the effect of smoking and body mass index(BMI) on lung cancer incidence density in male workers.Methods Risk factors of cardiovascular diseases in baseline were surveyed in 1974,1979 and 1980 for 5 137 men aged more than 18 years old from Beijing Capital Steel and Iron Company.Follow-up was carried out to 2001;all diseases were identified by uniform standard.Cox proportional hazards model was used to analyze the relationship between smoking,BMI and lung cancer.Results During mean follow-ups of 20.8 years,106 cases of lung cancer occurred.The crude incident rates of lung cancer were 102.2 cases per 100 000 person-years.After adjustment for age,BMI and other established risk factors,cigarettes consumption of greater than 20 cigarettes/day versus no smoking was associated with a relative risk of lung cancer of 3.45(95% confidence interval(CI): 1.58～7.53).In categories of BMI of less than 18.5(underweight),18.5～24.9(normal weight) and more than 25 kg/m2(overweight and obesity),adjusting for age and other covariables,all workers and smoking workers both showed decreasing tendencies in relative risks of lung cancer in higher BMI groups.The pattern was similar after excluding the early 5-year lung cancer patients.Grouping in smoking and BMI levels,compared with underweight smokers,the relative risks for lung cancer of normal-weight nonsmokers and nonsmokers with overweight and obesity,as well as smokers with overweight and obesity were 0.25(95% CI: 0.08～0.84),0.16(95% CI: 0.04～0.74) and 0.23(95% CI: 0.07～0.77),respectively.Smokers with underweight had higher risk for lung cancer.Conclusion Smoking and underweight increased the risk of lung cancer.Keeping normal weight and giving up tobacco were important for the prevention of lung cancer.

Objective　 To study the prevalence and relevant risk factors of low blood pressure and its influence on cardiovascular diseases in China. Methods　A cross-sectional study for low blood pressure was conducted using the data of the third national survey of blood pressure in 1991. Low blood pressure was defined for systolic (SBP) and diastolic (DBP) pressure less than the tenth percentile for the sample (SBP≤98mmHg and DBP≤60mmHg). Results　The prevalence of low blood pressure for males and females were 2.7% and 7.4%, respectively. The prevalence of low blood pressure for females was higher than that of males (P<0.01). Prevalence of low blood pressure was 7.62%, 6.97%, 4.40%, 3.22%, 2.65%, 1.94% for age groups 15～, 25～, 35～, 45～, 55～, 65～, respectively. The prevalence of low blood pressure was gradually declined with aging. There was large variation in the prevalence of low blood pressure for different minorities. The prevalence of low blood pressure was higher in the southern rather than the northern part of China. Logistic regression showed that the age (OR 0.97, 95%CI 0.97～0.98, per 10 mmHg), BMI (OR 0.80, 95%CI 0.80～0.81), drinking (OR 0.89, 95%CI 0.86～0.93) and heart rate (OR 0.981, 95%CI 0.980～0.982) had reverse relationship with low blood pressure. The sex had a positive relationship with low blood pressure. The prevalence of stroke and myocardial infarction in the population with low blood pressure was lower than that of normal pressure or hypertension (P<0.01). Conclusion　The prevalence and relevant risk factors of low blood pressure in China were various. We speculate that low blood pressure in Chinese population appears to be a normal state of physiology.The difinite influence in health needs cohort studies to confirm.

Objective To study the impact of active control of the trajectory of the center of gravity on the effectiveness of balance training and balance assessment. Methods Two groups of subjects ( group 1 30-45 years old, group 2 45-60 years old ) were evaluated and trained using both active center of gravity trajectory control and static balance methods. Results The percentages of success in controlling the center of gravity were the same when both groups were trained using static balance. Group 1's success percentage was higher than that of group 2 after active center of gravity trajectory training. Their affected lower limbs performed better in wave trace training than after static balance training, and performance improved with increased wave trace amplitude. Conclusions Wave tracing can stimulate the lower limbs of patients with active control force and improve their balance. The wave assessment is superior to static assessment, as it can objectively reflect ability in active center of gravity control and adjust the lower limbs of subjects whose static balance ability is at the same level.

Objective To study the influence of theaflavin on the expressions of TLR4 and release of TNF-αand IL-6 in primari-ly cultured rat airway epithelial cells .Methods Lipopolysacchride(LPS) was adopted to establish the in vitro inflammatory injury model of rat airway epithelial cell ,the TNF-αand IL-6 secreted by the airway epithelial cells and the TLR4 protein level in the air-way epithelial cells were detected with ELISA and the expressions of TLR4 mRNA was detected with RT-PCR .Results LPS sig-nificantly induced the airway epithelial cells to secrete TNF-αand IL-6 ,and enhanced the TLR4 mRNA and TLR4 protein expres-sion(P<0 .01) .Theaflavin could inhibit LPS induced TNF-αand IL-6 secretion and TLR4 gene expression(P<0 .05) ,which was related with the theaflavin concentration (P<0 .05) .Conclusion In rat airway epithelial cell culture ,the anti-inflammatory effect of theaflavin may be decrease the release of inflammatory cytokines via inhibiting TLR 4 gene expression and LPS/TLR4 signal trans-duction pathway .
