Objective To analyze the prevalence and risk factors related to the diabetic patients with hypertension in the Kailuan group workers.Methods A total of 9 498 type 2 diabetic patients were followed up for 5 years,regarding myocardial infarction,stroke,and death incident.The cumulative incidence of hypertension in diabetic patients and the evaluated risk factors of hypertension were analyzed.Results The prevalence of hypertension in 9 489 subjects with diabetes was 63.3％,higher than that in subjects without diabetes(42.0％,P＜0.01).Aging,smoking,obesity,high blood levels of triglycerides,total cholesterol,and low-density lipoprotein-cholesterol were the risk factors of diabetic patients with hypertension,in whom the morbidity of myocardial infarction,cerebral infarction,cerebral hemorrhage,and renal dysfunction was 3.3％,6.0％,0.9％,and 18.8％,respectively,all higher than those (2.1％,2.6％,0.3％,and 10.9％) in diabetic patients without hypertension (P＜0.01).By the end of follow-up for 5 years,incidences of cerebral infarction,cerebral hemorrhage,and death in diabetic patients with hypertension were higher than those with normal blood pressure (P＜0.05),but no difference in incidences of myocardial infarction between the 2 groups (P＞0.05).The 5-years cumulative incidence of hypertension in the diabetic population was 40.1％.Male sex,smoking,snoring,obesity,and hypertriglyceridemia were the risk factors of hypertension in diabetic patients (P ＜ 0.05).Conclusion The prevalence and the 5-years cumulative incidence of hypertension in diabetic patients increased significantly.Diabetic patients with hypertension may have higher risk of cerebrovascular events and kidney dysfunction.

Objective To investigate the effect of comprehensive intervention including education, lifestyle intervention and drug intervention for patients with hypertension in Kailuan community. Methods Employees who took part in the health checkup of Kailuan Group, Ltd. from June 2008 to June 2009 were enrolled in this study. The changes of hypertension awareness, treatment and control rates and cardiovascular health behaviors and factors have been observed in the follow-up. Results A total of 5 361 patients with hypertension were enrolled. After a period of 2 years of follow-up, the treatment rate and up to standard rate hypertension were significantly increased compared to pre-intervention (11.90%vs. 100.00%;0.82% vs. 36.93%. P<0.01). After comprehensive intervention, the average score of ideal cardiovascular health behaviors and factors increased from (6.85 ± 1.90) to (7.52 ± 1.92) (P<0.01). Conclusion Comprehensive intervention is an effective means for the prevention and control of hypertension in the community.

Objective To investigate the change of high sensitivity c-reaction protein( hs-CRP)on carotid artery plaque. Methods A total of 5 852 individuals were selected as our subjects who randomly stratified from the health examination survey participants in Tangshan Kailuan Company community during 2006 - 2007. A total of 5 440 people(age above 40 years old,free of stroke,transient ischemic attack(TIA)and myocardial infarction ) were qualified and enrolled in the final analysis. A questionnaire survey,blood biochemical analysis and carotid artery ultrasound examination were finished by trained medical staff. According to the hs-CRP 3 mg measurements at the first and third times health examinations,all subjects were divided into four groups,including continued decreasing group(hs-CRP < 3 mg/ L),decreasing group(hs-CRP decreased from≥3 mg/ L to < 3 mg/ L ),increasing group((hs-CRP increased from < 3 mg/ L to≥3 mg/ L)and continued high group((hs-CRP ≥3 mg/ L). Multiple logistic regression analysis was used to test the impact of change of hs-CRP on carotid artery plaque. Results Incidence of carotid artery plaques in continued decreasing, decreasing,increasing and continued high groups were 33. 6%(1 308 / 3 577),44. 7%(178 / 398),45. 1%(186 / 412)and 54. 9%(151 / 275),respectively. The dependent variable was named based on carotid artery plaque(1 = plaque and 0 = no plaque),and in dependent variable was named based on hs-CRP value change (0 = continued decreasing group;1 = decreasing group;2 = increasing group;3 = continued high group). Multiply factors logistic regression analysis showed that the risk of carotid artery plaques for women increased compared to decreasing group( RR = 1. 17,95% CI:1. 01 - 1. 35,P = 0. 035). After adjusting gender,age,smoking,low density lipoprotein cholesterol,fasting blood-glucose,baseline lg( hs-CRP)and body mass index,the risks of developing carotid artery plague in increasing group and continued high group were increased compared to decreasing group among the women and whole population(for all subject:RR = 1. 33,95% CI:1. 04 - 1. 70,P =0. 023;for women subject:RR = 1. 63,95% CI:1. 08 - 2. 46,P = 0. 021). Conclusion Increasing hs-CRP is a risk factors of incidence of carotid artery plaque possibly.

Objective To analyze the main clinical features and impact factors of simple renal cyst (SRC), and to provide evidence for the future prevation and cure of simple renal cysts.Methods In this crosssectional study,a total number of 91 433 participants(aged 18-98 years old) were included who underwent health examinations during 2012-2014.The main life styles and clinical features of each participants were recored,and blood biochemistry test, urinanalysis and renal ultrasonography were performed.Results The prevalence of SRC was 2.70％ (2 465 subjects were diagnosed by ultrasonography).It was higher in men than women(2.95％ vs.1.68％, P =0.00), which was increased with the increasing of age (respectively 0.37％, 0.57％, 1.30％ ,2.69％ ,4.46％ and 6.91％ in the group of ≤29year,30-39 year,40-49 year,50-59 year,60 -69 year and ≥70 year,P＜0.01).The maximum diameter of simple renal cysts were (2.6±1.7) cm.Age,rate of men, body mass index, glucose, total cholesterol, creatinine, urea nitrogen, and urinary protein positive rate, kidney stone prevalence were higher in SRC group(respectively (61.11±11.24)year vs.(51.37±13.72) year, 87.59％ vs.79.88％, (25.27 ± 3.19) kg/m2 vs.(24.97 ± 3.35) kg/m2, (6.09 ± 2.08) mmol/L vs.(5.70 ± 1.85) mmol/L, (5.11 ± 1.54) mmol/L vs.(5.02 ± 1.37) mmol/L, (90.71 ± 34.84) μmol/L vs.(80.72 ±28.04) μmol/L, (6.03±3.60) mmol/L vs.(5.55±5.15) mmol/L,7.46％ vs.4.25％ ,7.06％ vs.1.28％ ,P ＜0.01) ,but glomerular filtration rate, triglycerides, rate of like salty, drink, smoke was lower than the group withoutSRC((79.01±19.89) ml/(min· 1.73 m2) vs.91.74±21.8 ml/(min · 1.73 m2),(1.57±1.48) mmol/L vs.(1.69± 1.82) mmol/L, 4.38％ vs.7.94％, 22.68％ vs.30.75％, 24.91％ vs.30.97％;P＜ 0.01).But,there was no difference between these two groups in serum uric acid ((309.16± 85.79) μmol/L vs.(312.38±91.22) μmol/L,P＞0.05).SRC as a dependent variable of multivariate log regression analysis.The result showed the OR of age, gender, fasting blood glucose, urea nitrogen, glomerular filtration rate, positive urine protein,kidney stone were respectively 1.040, 1.862, 1.035, 1.005,0.982, 1.254, 4.526, 95％ CI =1.037 -1.045,1.643-2.110,1.017-1.053,1.000-1.010, 0.980-0.984, 1.068-1.473,3.812-5.374;P ＜0.01).While the OR of multiple SRC was 0.43,95％ CI: 0.210-0.867 (P＜0.05) , when kidney stone as a dependent variable.Conclusion Old-age males are high risk population of catching SRC.Kidney stone and positive urine protein are important risk factors of SRC.Meanwhile kidney stone more easily induce single and small SRC.SRC is a key risk factor to induce renal function decrease.Therefore, GFR is a sensitive index of renal disfunction that induced by SRC.

Objective To Investigate the relationship between an in sertion (I)/deletion (D) polymorphism for angiotensin converting enzyme (ACE) and A(1166)C Polymorphism of angiotensin type 1 receptor(AT 1R) genes in patients with vertebro basilar insufficiency(VBI). Methods In this study, We examined 120 patients with VBI and 146 normal controls. The genotype for I/D of ACE and A(1166)C of AT 1R was assessed using polymerase chain reaction (PCR) and refrained fragment length polymorphism(RFLP), respectively. Then we compared the genotype frequency distribution among subjects.Results As a whole, there was significant difference in the distribution of ACE (I/I, I/D and D/D) and AT 1R (A/A and A/C), respectively. D allele frequency was higher in patients compared with the normal controls. Our study also revealed that Ⅱ AA and DD AA genotype frequency in VBI was higher than that in the normal controls.Conclusion The D allele for ACE and C(1166) allele of AT 1R may correlated with VBI.Ⅱ genotype for ACE and AA genotype had a positive con influence on the VBI. The affection of DD AA genotype on VBI was negative.

Objective: To investigate the relationship between blood triglyceride (TG) level and brachial-ankle pulse wave velocity (baPWV) in relevant population. Methods: A total of 22622 participants in Kailuan area were enrolled and divided into 4 ranks: Stroke rank, n=5219, Aged rank n=1754, Pregnancy hypertension Rank, n=1561and Peripheral vascular diseases rank, n=14088. All participants finished baPWV examination. The relationship between TG and baPWV was studied by partial correlation analysis, the impact of TG on baPWV was assessed by multivariate linear regression and multivariate Logistic regression analysis. Results: There were 21713 subjects finally enrolled for cohort study and 909 subjects excluded for missing TG information. With elevated TG levels, the average baPWV and the detection rate of baPWV≥1400 cm/s showed the increasing trend. Partial correlation analysis presented that TG level was positively related to baPWV, r=0.235; with adjusted age and gender, TG was still positively related to baPWV, r=0.080. Logistic regression analysis indicated that with other adjusted confounding factors, compared with the first quartile of TG, the second quartile, third quartile and fourth quartile of TG were the risk factors for baPWV≥1400 cm/s, OR=1.161, 95% CI (1.035-1.302), OR=1.312, 95% (1.165-1.476) and OR=1.652, 95% CI (1.463-1.865) respectively. Conclusion: Blood TG level was positively and independently related to baPWV in relevant population.
