Total 11 008 subjects underwent routine health check-up at Tianjin General Hospital in 2008. The results showed that the rate of hyperuricemia was 11.56% ( 1272/11 008 ) in this population, 17. 17% ( 1216/7082 ) for male, and 1.43% (56/3926) for female (P ＜0. 05). The serum uric acid levels were positively correlates with body mass index ( r = 0. 346), waist circumference ( r = 0. 449), systolic blood pressure ( r = 0. 193 ), diastolic blood pressure ( r = 0. 240), total cholesterol levels ( r = 0. 240) and triglyceride ester levels ( r = 0. 284 ). The factors including overweight, hypertension, hyperlipidemia and hyperglycosemia were clustered in subjects with hyperuricemia.

Objective To explore the association between the infection rate of Helicobacter pylori (Hp) and intake frequency of capsicum in dietary pattern. Methods A total of 914 health check-up participants were recruited from Tianjin Medical University General Hospital (male: 510,female:404). All participants were asked about the intake frequency of capsicum. Diagnostic criteria of the Hp infection included positive C13 breath test. Results The intake frequency of capsicum was ≥2 times/week, 1 time/week and <1 time/week. The infection rate of Hp was 56.08%, 49.04% and 48.29%. After adjusting for covariates, compared with the≥2 times/week, the odds ratios(95%confidence interval)of intake frequency of capsicum 1 time/week and <1 time/week: the frequency of capsicum intake ≥2 times/week was 1.00 (reference), the frequency of capsicum intake 1 time/week was 0.57(0.33-0.97) and the frequency of capsicum intake<1 time/week was 0.69(0.42-1.14) in men;the frequency of capsicum intake≥2 times/week was 1.00 (reference), the frequency of capsicum intake 1 time/week was 1.01(0.54-1.88), and the frequency of capsicum intake<1 time/week was 0.71(0.41-1.23) in women. Conclusions This study found that food intake frequency of capsicum≥2 times/week was associated with the infection rate of Hp in men. But similar relationship was not observed in women.

To investigate the association between Helicobacter pylori ( Hp ) infection and type 2 diabetes.Total 4 129 health check up subjects aged (49.1 ±11.3) years (18-92 years), including 2 649 males and 1 480 females were enrolled in this cross-section study.Hp infection was confirmed by 13 C-urea breath test;type 2 diabetes mellitus was diagnosed according to WHO criteria (1999).Single factor analysis and multiple regression analysis were used to evaluate the association between Hp affection and the prevalence of type 2 diabetes.Hp infection rate in diabetic group was significantly higher than that in non-diabetic group (45.6%vs.39.0%, P<0.05).Hp infection rate in subjects with newly diagnosed diabetes was highest than those with previously diagnosed diabetes and non-diabetic subjects ( P<0.05).The glycosylated hemoglobin level in Hp infection group was higher than that in non infection group [ ( 5.88 ±0.64 )% vs.( 5.62 ± 0.88)%, P<0.05];the fasting plasma glucose and postprandial blood glucose levels in Hp infection group were also higher than those in non-infection group ( P<0.05 ).Logistic regression analysis showed that Hp infection was one of the independent risk factors of type 2 diabetes (OR=2.002, 95%CI:1.564-2.563, P<0.05).The study indicates that Hp infection is closely associated with type 2 diabetes mellitus.

Hyperuricemia and metabolic syndrome were studied in 17 762 subjects of Tianjin Municipality from July 2007 to July 2009. The overall prevalence rate of hyperuricemia was 12. 16% (2160cases) , the rate in males was significantly higher than that in females (15. 71% vs. 6. 51% , P <0. 01).The overall prevalence rate of metabolic syndrome was 25. 56% (4540 cases) , the rate in males was also higher than that in females (28. 17% vs. 21. 40% , P <0. 01). Binary logistic regression analysis disclosed that females with high uric acid were twice likely to suffer from metabolic syndrome than males; and female ≤ 44 years with hyperuricemia had the highest odd ratio for metabolic syndrome.

Objective Neutrophil/lymphocyte ratio (NLR) is an easy-to-analyze inflammation biomarker but few studies have assessed the relationship between NLR and type 2 diabetes. In order to evaluate how NLR is related to type 2 diabetes, we designed a large scale cross?sectional study in an adult population. Method A cross?sectional study (including 49 861 men and 40 376 women) was conducted on participants recruited from the Health Management Center of Tianjin Medical University General Hospital in Tianjin, China. Measurements of neutrophil and lymphocyte counts, fasting blood glucose and other potential confounding factors were performed. Type 2 diabetes was defined according to the criteria of American Diabetes Association. Adjusted logistic regression models were used to assess relationships between NLR quintiles and type 2 diabetes. Result In the final multivariate models, the odds ratios (95% confidence interval) for T2D across NLR quintiles were 1.00 (Reference), 1.19 (1.05, 1.35), 1.33 (1.17, 1.50), 1.28 (1.13, 1.44) and 1.34 (1.19, 1.51) (P for trend<0.000 1), in men. Similar relationships were also observed in women. Conclusion This study demonstrated that NLR was related to the prevalence of type 2 diabetes in men and women, and suggesting that NLR may be an efficient and accurate prognostic biomarker for type 2 diabetes.

Objective To investigate blood uric acid levels in health check-up receivers in Tianjin City. Methods Blood uric acid levels in 28 661 health check-up participants were tested and the incidence of hyperuricaemia was analyzed. Blood pressure, body mass index, blood sugar, cholesterol and triglyceride were measured and compared. Results The average level of blood uric acid was (349±73 ) μ mol/L in male,and (256±59) μmol/L in female. The peak value in male was found in the 30 to 39 years old group,while in female the age was increased to 70 years old. The incidence of hyperuricaemia was higher in male ( 15. 2% vs 6. 3% ,P＜0.01). The level of blood sugar,triglycerides and total cholesterol was higher in the hyperuricaemia group. Also in the hyperuricaemia group, the incidence of overweight/obesity,hyperglycaemia, hyperlipidemia and hypertension was higher. Conclusions The incidence of hyperuricaemia in routine health check-up individuals in Tianjin City could be 11.3%. Blood uric acid may be significantly associated with metabolism.

Total 10 450 people received health check-up in our hospital from March 2009 to December 2010.The subjects were classified as high-risk for type 2 diabetes mellitus ( DM ) group ( n =9016) and non-high-risk group (n =1434).The rate of new DM was 3.36％ (303/9016) and the rate of impaired glucose regulation (IGR) was 12.38％ (1117/9016) in high-risk group; while in non-high-risk group there was no new DM cases,and IGR rate was 2.58％ (37/1434).The detection rate of IGR and DM significantly increased with the increasing rate of risk factor and numbers (P ＜ 0.01 ).Logistic regression analysis revealed that the abnormal glucose metabolism was associated with age,male,positive family history,heart rate,hypertension,abnormal lipid metabolism and hyperuricacidemia.The results suggest that subjects with multiple risk factors should be the key population for prevention and screening of type 2 diabetes.

Objective To investigate the relationships between different dietary patterns and serum uric acid in Tianjin residents. Method By cross-sectional study design, 11282 subjects were studied via lifestyle questionnaires (including a valid food frequency questionnaire), physical examination and laboratory tests. Using factor analysis method to establish the dietary patterns, and relationships between different dietary patterns and serum uric acid were analyzed. Results Factor analysis showed 3 kinds of dietary patterns, including eastern dietary pattern, vegetable diets and Tianjin dietary pattern. There were more males in hyperuricemic population, who have a higher BMI, waist circumference, blood lipids, blood pressure and blood sugar levels, and also higher proportion of metabolic syndrome, smokers and alcohol drinkers. In addition, hyperuricemia patients had a higher level of social status and income. After adjustments for age, sex, BMI, smoking habits, alcohol consumption, hypertension, hyperlipidemia, education level, occupational status, energy intake, physical activity and metabolic syndrome, logistic regression analysis showed the odds ratio (95%confidence interval) for hyperuricemia across the quartiles of 3 dietary patterns as follows: 1.00, 1.07 (0.91, 1.25), 0.96 (0.82, 1.14), 1.12 (0.94, 1.33);1.00, 1.03 (0.88, 1.21), 1.04 (0.88, 1.23), 1.00 (0.84, 1.19); 1.00, 1.28 (1.08, 1.52), 1.40 (1.22, 1.71), 1.37 (1.15, 1.63), respectively. Significantly positive correlation was shown between Tianjin dietary pattern and hyperuricemia. Conclusion Tianjin residents' Tianjin dietary pattern is closely related to serum uric acid levels. Tianjin dietary patterns have characteristics of high calorie, high fat, high protein. Healthy eating habits have significant importance to prevent occurrence of hyperuricemia.

Objective To investigate the prevalence and risk factors of impaired glucose regulation (IGF) in health check-up populations in Tianjin.Methods A total of10126 individuals were assigned to group according the1999 World Health Organization (WHO) criteria for diabetes mellitus ( DM ).Clinical characteristics and the prevalence of DM were compared between the groups. Student's t test,Chi-square test and logistic regression were used for data analysis.Results The incidence of IGR was much higher in male than in female (x3 =136.2,P ＜0.05).Abnormal glucose metabolism showed an increasing trend with age ( P＜0.05 ).In logistic regression analysis,age,male,family history of DM,overweight/obesity,hypertension,hypertriglyceridemia and hyperuricemia were risk factors of IGR.Conclusion Age,male,overweight/obesity,family history of DM,hypertension,hypertriglyceridemia and hyperuricemia could be risk factors of IGR.Early screening and intervention may help to prevent the development of DM.
