ABSTRACT: To investigate the significance of high sensitivity C-reactive protein (hsCRP) levels in serum for detecting type 2 diabetes mellitus (T2DM) patients at risk of developing nonalcoholic fatty liver (NAFLD).
Individuals with T2DM (n = 9489) were recruited from the Kailuan Company between 2006 and 2007 for the first phase of this community-based prospective cohort study. For the second phase of the study, the original cohort was recruited for follow-up (at two years from each subject's original enrollment date (baseline)). The total followed-up subjects (n = 2802; 2344 males, 458 females, 22-88 years old) were categorized into quartiles according to baseline measurements of serum hsCRP levels (less than or equal to 0.30, > 0.30-0.60, > 0.60-1.92 and > 1.92 mg/L) and used to determine the relationship between change in incidence rates of NAFLD and predictive value of baseline serum hsCRP levels by logistic regression analysis.
Twenty-nine percent (n = 813) of the followed-up subjects developed NAFLD. The incidence (%) of NAFLD at the two-year follow-up had increased in conjunction with the level of serum hsCRP detected at baseline (quartile 1: 22.5%, 2: 27.3%, 3: 32.1%, and 4: 34.3%; all, P less than 0.01). It was found that the subjects in the highest quartile had an increased risk of NAFLD (odds ratio (OR) = 1.80, 95% confidence interval (CI): 1.42-2.28, P less than 0.01), as compared with those in the lowest quartile. Moreover, when the regression model was adjusted for baseline factors of age, sex, triglycerides, total cholesterol, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, fasting serum glucose, and body mass index, the risk of NAFLD remained significantly higher for the highest quartile (vs. the lowest quartile; OR = 1.49, 95% CI: 1.16-1.91, P less than 0.01).
Serum hsCRP levels may be predictive of development of NAFLD in individuals with type 2 diabetes mellitus. The risk of NAFLD increases in parallel with increasing levels of serum hsCRP.

ABSTRACT: To explore the impact of ideal health behaviors and health factors on the detection rate of the carotid plaques.
Subjects with previous stroke, TIA, myocardial infarction were excluded from the study. A total of 5852 employees (active and retired employers from Tangshan Kailuan company) aged 40 years and over were included through stratified random sampling. Information was obtained from the unified questionnaire, measurements of blood biochemistry and carotid artery ultrasonography.
(1) The carotid artery plaque detection rates were 67.0%, 52.3%, 50.5%, 44.3%, 37.2%, 31.9%, 26.1% and 4.2% in the groups with 0, 1, 2, 3, 4, 5, 6 and 7 components of ideal cardiovascular health behaviors and health factors, respectively. (2) The carotid artery plaques total burden score [TBS: M (Q1, Q3)] were 7(7,7), 7(5,7), 7(5,7), 5(3,5), 5(3,5), 5(3,5), 3(3,3), 3(3,3) in the groups with 0, 1, 2, 3, 4, 5, 6 and 7 components of ideal cardiovascular health behaviors and health factors, respectively. (3) Multiple logistic regression analysis showed that 3, 4, 5 and greater than 5 components of ideal cardiovascular health behaviors and health factors were protective factors against carotid plaques compared to less than 2 components of ideal cardiovascular health behaviors and factors (all P < 0.05), the OR (95%CI) values were 0.78 (0.62 - 0.98), 0.53(0.62 - 0.98), 0.52 (0.39 - 0.71) and 0.40 (0.25 - 0.64), respectively.
Increasing ideal cardiovascular health behaviors and factors are negatively linked with the detection rate and TBS of the carotid plaques.

ABSTRACT: OBJECTIVE: To compare the incidence of cardio-cerebral vascular events between pregnancy induced hypertension (PIH) women and non-PIH(NPIH) women. METHODS: Ambispective cohort study method was used and 4630 pregnant women giving birth during October 1976 to December 2008 in our hospital and participated the healthy examination between July 2006 and October 2007 at Kailuan medical group were included and divided into PIH group (n = 694) and NPIH group (n = 3936) by the history of PIH. Incidence of cardio-cerebral vascular events (myocardial infarction, cerebral infarction and cerebral hemorrhage) was obtained during follow-up. Multivariable Cox proportional hazards regression models was used to assess the relative risk of cardio-cerebral vascular events. RESULTS: (1) The follow-up time was 2 to 34 (15.32 ± 7.94) years. (2) The childbearing age, systolic blood pressure and diastolic blood pressure before delivery were significantly higher while gestational weeks and weight of newborn were significantly less in PIH group than in NPIH group (all P < 0.01). Levels of systolic blood pressure, diastolic blood pressure, waist circumference, body mass index, triglyceride, total cholesterol and fasting blood glucose during healthy examination between July 2006 and October 2007 were significantly higher in PIH group than in NPIH group (P < 0.05 or P < 0.01). (3) There were 71 cardio-cerebral vascular events during the follow-up. In PIH group, the incidence rate of cardio-cerebral vascular events, myocardial infarction and cerebral infarction was 20.64%, 11.08% and 8.67%, respectively, while the corresponding incidence rate was 7.82%, 4.02% and 2.67% in NPIH group (all P < 0.01). After adjustment for other traditional cardiovascular risk factors, the risk of total cardio-cerebral vascular events, myocardial infarction and cerebral infarction in PIH group was 2.99 fold (95%CI: 1.80 - 4.95), 3.91 fold (95%CI: 1.71 - 8.91) and 3.96 fold (95%CI: 1.95 - 8.05) higher than in NPIH group. CONCLUSION: PIH is an independent risk factor for cardio-cerebral vascular events.

ABSTRACT: This study investigated the impact of metabolic syndrome on the development of cardio-cerebral vascular (CVD) events in a pre-hypertensive population.
The data used in this prospective study was derived from the Kailuan study cohort (n = 101 510). Prehypertension was diagnosed in 29 968 (mean age: 50 ± 9 years and 23 744 males) individuals by the JNC VII criteria and these subjects were further classified into metabolic syndrome positive (MS+, n = 3447) and MS negative (MS-, n = 26 521) groups according to the modified 2004 Chinese Diabetes Society criteria. Subjects were followed up for 38 - 53 (mean 47 ± 5) months and first-ever CVD events were recorded. Baseline anthropometric and laboratory features were obtained by physical examination from June 2006 to October 2007 and the last follow-up day was December 31, 2010. Multivariable Cox proportional hazards regression models were used to analyze the risk factors of first-ever CVD events.
There were 354 CVD events during follow up. The incidences of CVD events (1.80% vs. 1.28%) and cerebral infarction (1.10% vs. 0.57%) were significantly higher in the MS+ group than in the MS- group (all P < 0.05). After adjustment for other established CVD risk factors, the hazards ratio was 1.45 (95%CI: 1.10 - 1.92) for total CVD events and 1.84 (95%CI: 1.27 - 2.67) for cerebral infarction events in MS+ group.
In this cohort, metabolic syndrome is linked with increased risk for CVD events.

ABSTRACT: To estimate the relationship between the risk stratification of patients with diabetes and their clinical endpoint events.
In this cohort study, we prospectively followed 8302 individuals under the following situations:contents of fasting plasma glucose ≥ 7.0 mmol/L, being diagnosed as diabetes or having used hypoglycemic drugs from Kailuan study in which 101 510 employees (81 110 males, 20 400 females, who were being employed and those retired from the company were included) from the Kailuan Company, were screened. During the 38 - 53 (48.01 ± 3.14) months of follow-up period, a new heart or cerebrovascular events were ascertained every six months. The impacts of different risk stratification in diabetic population on the incidence rates of cardiovascular and cerebrovascular events were estimated.
Using the definitions of "people with ischemic cardiovascular disease incidence of 10-year risk assessment methods" developed by the Chinese Academy of Medical Sciences, Institute of Cardiovascular Disease, the study cohort was divided into four groups, namely, very low-risk, low risk, medium risk and high risk. (1) Along with the increasing risk of the disease, the incidence rates of total cardiovascular and cerebrovascular events, myocardial infarction, stroke, cardiovascular death and all-cause death rate also gradually increased and the differences were statistically significant (P < 0.01). However, the difference on incidence rate of sudden death was not significantly different (P > 0.05). (2) Compared to the very low-risk group, the age and sex adjusted relative risk for cardiovascular and cerebrovascular events were 1.42 (95%CI: 1.02 - 1.96, P < 0.05), 2.26 (95%CI: 1.67 - 3.04, P < 0.01) for those with medium and high risk groups, respectively.
In diabetic patients, those risk factors as age, hypertension, body mass index, total cholesterol and smoking having been used on ischemic cardiovascular disease, could also be used to predict the occurrence of cardiovascular events. Along with the increasing risk factors, the risk of cardiovascular events incidence also increased.

ABSTRACT: To observe the prevalence and distribution of ideal cardiovascular health behavior.
Health examination data between 2008 to 2009 from the employees of Kailuan Group were analyzed.
A total of 101 333 subjects took part in the health examination, subjects with previous myocardial infarction (n = 871), stroke (n = 2255), myocardial infarction and stroke (n = 162) and subjects with incomplete examination data (n = 9311) were excluded and 88 534 subjects were included for final analysis [mean age (50.6 ± 12.3) years, male 69 916]. (1) Body mass index (BMI), systolic and diastolic pressure, cholesterol (TC) and triglyceride were significantly higher in males than in females (all P < 0.05), women's income and the education lever were significantly higher than men (P < 0.05). (2) The distribution of ideal cardiovascular health behavior (smoking, BMI, physical exercise, salt intake) was 55.8%, 41.4%, 18.9% and 14.0% respectively among the population; the ideal cardiovascular factors (fasting blood glucose, TC, blood pressure) was 80.9%, 61.8% and 18.5%, respectively. (3) The subjects with distribution of seven, six, five, four ideal cardiovascular health behavior and factors was 0.1%, 1.9%, 9.1%, 20.3%, respectively. (4) Multiple logistic regression analysis showed that female, age < 55 and high education level were associated with the ideal cardiovascular health status with a RR value (95%CI) of 4.52 (4.32 - 4.72), 1.46 (1.39 - 1.53) and 2.23 (2.10 - 2.37), respectively.
The prevalence of ideal cardiovascular health is extremely low in the study population, most persons were not in the ideal cardiovascular health behavior and factors and female, age < 55 and high education level are linked with ideal cardiovascular health status.

ABSTRACT: To evaluate the predictive value of baseline serum high sensitivity C-reactive protein for the first cardio-cerebral vascular event in the population with diabetes.
In this prospective cohort study, a total of 101 510 employees of Kai Luan Group, who received healthy examination from July 2006 to October 2007, were screened and 7865 subjects with fasting plasma glucose ≥ 7.0 mmol/L or known diabetes mellitus and under insulin or hypoglycemic drugs therapy were followed up for 38 - 53 (48.02 ± 3.14) months.
(1) Incidence rates of total cardio-cerebral vascular events, cerebral infarction and myocardial infarction increased in proportion to increased levels of baseline hsCRP (P < 0.01). After adjusting for age, gender, body mass index (BMI), systolic blood pressure (SBP), diastolic blood pressure (DBP), total cholesterol (TC), triglyceride (TG), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C) and cigarette smoking, multivariate Cox's proportional hazards regression analysis indicated that the individuals in the highest quartile of hsCRP levels group (hsCRP ≥ 2.50 mg/L) had an increased risk of total cardio-cerebral vascular events (RR: 1.64, 95% CI: 1.20 - 2.24), cerebral infarction (RR: 1.52, 95% CI: 1.03 - 2.24), myocardial infarction (RR: 2.57, 95% CI: 1.34 - 4.91) compared with those in the lowest quartile group (hsCRP < 0.41 mg/L). (2) Higher baseline hsCRP levels were associated with aging, female gender, higher BMI, SBP, DBP, fasting blood glucose, TC, TG, LDL-C levels and lower HDL-C levels (all P < 0.05).
Baseline hsCRP level is associated with increased first cardio-cerebral vascular event in the population with diabetes.

ABSTRACT: To valuate whether angiotensin converting enzyme (ACE) gene insertion/deletion (I/D) polymorphism and aldosterone synthase (CYP11B2) gene -344T/C polymorphism are associated with individual response to hydrochlorothiazide (HCTZ) in the Han Chinese population with essential hypertension. We enrolled 829 mild/moderate hypertensive patients and 12.5 mg of HCTZ was given daily. After 6 weeks, the results showed that the ACE I/D polymorphism, not the CYP11B2 -344T/C polymorphism, was associated with systolic blood pressure (SBP) response to HCTZ (P = 0.009) in the Han Chinese population with essential hypertension, with no interaction.

ABSTRACT: To observe the distribution and influence factors of serum high sensitivity C-reactive protein (hs-CRP) in general population.
In a cross-sectional population survey, a total of 101 510 subjects who were employed by Kailuan Group had been carried out a healthy examination in the period of 2006 to 2007. In the statistical analysis, we observed 91 123 subjects (males 72 805, females 18 318) who had full information and met the inclusion criteria of the study.
(1) The geometric means of hs-CRP were 0.70 mg/L, 0.70 mg/L and 0.73 mg/L in all subjects, males and females, respectively, the 95th percentiles were 6.28 mg/L, 6.20 mg/L and 6.49 mg/L, respectively. The concentrations of hs-CRP increased with age in both males and females (P trend = 0.001). Serum hs-CRP geometric mean was 0.54 mg/L and the 95th percentile was 5.40 mg/L in health group, while the geometric mean was 0.80 mg/L and the 95th percentile was 6.57 mg/L in non-health group. (2) Multiple linear regression analysis showed that concentrations of hs-CRP were positively associated with gender, age, systolic blood pressure, body mass index, total cholesterol, triglycerides, fasting blood glucose, smoking history, history of coronary heart disease and stroke history, but concentrations of hs-CRP were inversely related with diastolic blood pressure, high-density lipoprotein cholesterol and alcohol history.
Serum concentrations of hs-CRP level increased with age, concentrations of hs-CRP were higher in females than males; a variety of cardiovascular factors effected the concentrations of hs-CRP.

ABSTRACT: To study the risk prediction for new intracerebral hemorrhage (ICH) with high sensitivity C-reactive protein (hs-CRP) level.
In a retrospective, nested, case-controlled study, 323 cases of ICH were identified and matched with 646 controls. The hs-CRP levels at baseline were compared between the two groups. The relevance of different hs-CRP levels and the risk of ICH were analyzed.
The ICH group had a higher median hs-CRP levels (1.10 mg/L) as compared with the control group (0.66 mg/L) with significant difference (P<0.01). In addition, the increase of risk associated with hs-CRP levels was primarily observed in the individuals with the highest quartile of hs-CRP levels (>2.12 mg/L). These patients had an increased risk of ICH (OR 2.58, 95%CI 1.77 to 3.76) as compared with those in the lowest quartile (≤0.30 mg/L). Individuals with baseline hs-CRP levels above the specified cut point of 3 mg/L or more and those in the 80th percentile were at a markedly increased risk of ICH (for specified cut point of 3 mg/L, OR 2.26, 95%CI 1.60 - 3.20, P<0.01; for 80th percentile, OR 2.24, 95%CI 1.60 - 3.13, P<0.01, respectively).
Risk of ICH might be predicted with the level of hs-CRP. With the increase of hs-CRP level at baseline, the risk of ICH was increased.

ABSTRACT: To observe the prevalence, blood pressure change in prehypertensive population and associated cardiovascular risk factors.
Data from a prehypertensive cohort defined with the JNC-7 prehypertension diagnostic criteria were obtained in the employees of kailuan group during the health examination between 2006 to 2007 and the same population was revisited between 2008 to 2009 to observe the change of blood pressure and the associated determinants for blood pressure change.
(1) There were 25 474 prehypertensive during the 1(st) visit and 8361 subjects developed hypertension during the 2(nd) visit (35.3% in men and 23.3% in women, 27.2% with baseline blood pressure 120 - 129/80 - 84 mm Hg (1 mm Hg = 0.133 kPa) and 43.8% with baseline blood pressure 130 - 139/85 - 89 mm Hg, 34.3% with risk factors and 19.9% without risk factors). (2) Multiple logistic regression analysis showed that the baseline SBP, waist circumference, age, BMI, gender (male), DBP, TC, FBG, TG, LDL-C were the risk factors of blood pressure progression with a RR (95%CI) of 1.052 (1.048 - 1.056), 1.009 (1.006 - 1.013), 1.023 (1.021 - 1.026), 1.063 (1.052 - 1.074), 1.554 (1.442 - 1.675), 1.036 (1.029 - 1.043), 1.064 (1.037 - 1.093), 1.043 (1.024 - 1.062), 1.041 (1.021 - 1.062) and 1.035 (1.000 - 1.072), respectively.
A third (32.8%) prehypertensive population progressed into hypertension after two years, baseline SBP, waist circumference, age, BMI, gender (male), DBP, TC, FBG, TG, LDL-C were the risk factors of predicting blood pressure progression.

ABSTRACT: To explore the perpetual impact of pregnancy-induced hypertension on blood pressure.
This retrospective cohort study included 782 cases of pregnant women who hospitalized at Kailuan Linxi hospital between October 1976 and August 2001. Patients were divided to with pregnancy induced hypertension (PIH, n = 77) group and non pregnancy induced hypertension (NPIH, n = 705) group. Patients were followed for 5 to 34 years (mean 18.8 +/- 5.3 years), the incidence of essential hypertension was obtained in July 2006-September 2007.
(1) The cumulative incidence of essential hypertension during follow up was significantly high in PIH group (29.87%) than that in NPIH group 18.87% (P = 0.022). (2) At the final follow up, waist circumference; [(86.06 +/- 10.15) cm vs. (83.07 +/- 8.19) cm, P = 0.015], BMI [(24.83 +/- 4.01) kg/m(2) vs. (23.50 +/- 3.39) kg/m(2), P = 0.006], TC [(5.11 +/- 0.88) mmol/L vs. (4.89 +/- 0.94) mmol/L, P = 0.045] and GLU [(5.57 +/- 1.78) mmol/L vs. (5.20 +/- 1.38) mmol/L, P = 0.010] were all significantly higher in PIH group than those in NPIH group. (3) After adjustment of age and BMI, PIH was still significantly correlated with long-term systolic blood pressure levels (P = 0.048), fasting glucose level was also significantly associated with long-term systolic blood pressure. Age, BMI, white blood cell count and uric acid were also predictors for perpetual systolic and diastolic blood pressure levels.
Incidence of essential hypertension in women with PIH was higher than that in women without PIH. After adjustment of covariates including age, BMI, and glucose, PIH was significantly associated with the level of systolic blood pressure. BMI, fasting glucose and cholesterol levels might contribute to the increase of systolic blood pressure in patients with PIH.

ABSTRACT: To explore the impact of patient compliance on the long-term outcomes in hypertensive patients receiving hydrochlorothiazide (HCTZ) based combination therapy with spironolactone or captopril.
A total of 853 patients with mild to moderate hypertension were recruited and randomly divided into HCTZ group (HCTZ 12.5 mg q.d), spironolactone group (HCTZ 12.5 mg q.d and spironolactone 20 mg q.d), and captopril group (HCTZ 12.5 mg q.d and captopril 25 mg bid) after 2-week placebo washout period and 6-week loading period for HCTZ. Since the efficacy of combination therapy was proven to be better than monotherapy 1 year after therapy beginning, patients in HCTZ group were randomly assigned to spironolactone group or captopril group. The patients were followed up for 4 years. Patients were divided to compliance (n = 424) or non-compliance group (n = 429) according test drug taking questionnaire. During the follow-up time, the blood pressure and the outcomes were recorded monthly, and blood biochemical parameters were determined once a year.
At the end of follow up, incidence of cardio-cerebral vascular events was significantly lower in compliance group (2 fatal, 8 non-fatal) than that in noncompliance group (7 fatal, 21 non-fatal, P < 0.05). Systolic blood pressure [-(19.4 +/- 20.6) mm Hg, 1 mm Hg = 0.133 kPa] and diastolic blood pressure [-(10.7 +/- 13.5) mm Hg] were significantly reduced compared values at baseline and noncompliance group (all P < 0.001) while the reduction did not reach statistically significance in noncompliance group [-(7.3 +/- 18.2) mm Hg and -(3.5 +/- 10.2) mm Hg, all P > 0.05 vs. baseline]. The serum BUN, Cr and UA levels in the compliance group were significantly higher and the serum K(+), CHO, LDL-C level were significantly lower than baseline values. The serum BUN, UA levels in the compliance group were significantly higher while the serum K(+), cholesterol levels were significantly lower than those in the noncompliance group (all P < 0.05).
This study indicates that patient compliance could affect the long-term outcome and antihypertensive efficacy in hypertensive patients receiving HCTZ based combination therapy with spironolactone or captopril.

ABSTRACT: To explore the association between polymorphism in the ACE I/D gene and blood pressure-lowering response to hydrochlorothiazide (HCTZ) in 829 patients.
HCTZ 12.5 mg was taken once a day for six weeks. The blood pressure reduction and ratio reaching target blood pressure were compared in different ACE genotype groups.
The reduction in SBP of patients carrying DD was greater than that in other groups carrying II or ID (12.2 mmHg versus 5.4 mmHg, 12.2 mmHg versus 4.4 mmHg, respectively, P<0.05). The reduction in MAP of patients carrying DD was also greater than that in other groups carrying II or ID (6.9 mmHg versus 3.9 mmHg, 6.9 mmHg versus 3.6 mmHg, respectively, P<0.05). The ratio reaching target blood pressure in DD groups was significantly higher than that in II or ID groups (P<0.05). The pre-treatment SBP, DD genotype, aldosterone levels entered the multi-linear regression model significantly and might affect the reduction of SBP. The pre-treatment DBP, aldosterone levels, DD genotype entered the multi-linear regression model significantly and might affect the reduction of DBP. The pre-treatment MAP, DD genotype, aldosterone levels entered the multi-linear regression model significantly and might affect the reduction of MAP.
ACE genotyping is associated with blood pressure-lowering response to HCTZ. Specific genotypes might be associated with the response to specific antihypertensive treatment.

ABSTRACT: To examine whether there is an association essential hypertension pressure and a polymorphic Hind III biallelic marker in the non-recombining region of Y chromosome in Chinese Han people.
Peripheral blood samples were collected from 402 males with essential hypertension pressure and 455 age- and body height-matched healthy males as control group. Genomic DNA was extracted from the white blood cells. Segments of polymorphic Hind III restriction site of the Y chromosome were amplified from the genomic DNA by polymerase chain reaction (PCR). The PCR products were restricted with 10 U of Hind III overnight at 37 degrees C. The digested products were subjected to electrophoresis in 3% agarose gels, and stained with ethidium bromide.
The Hind III (+) genotype was found in 58.5% of the men with essential hypertension (235/402), significantly lower than that in the healthy men (64.4%, 302/455, P = 0.02). The systolic blood pressure of the men with Hind III (+) genotype was 133.8 mm Hg +/- 25.2 mm Hg, significantly lower than that of the Hind III (-) genotype (138.0 mm Hg +/- 27.0 mm Hg, P < 0.05), and the diastolic blood pressure (DBP) of the men with Hind III (+) genotype was 83.5 mm Hg +/- 13.3 mm Hg, significantly lower than that of the men with Hind III (-) genotype (85.9 mm Hg +/- 14.4 mm Hg, P = 0.01), and the mean arterial pressure of the men with Hind III (+) genotype was 100.2 mm Hg +/- 16.5 mm Hg, significantly lower than that of the of the men with Hind III (+) genotype was (103.3 mm Hg +/- 17.6 mm Hg, P = 0.01).
Polymorphic Hind III restriction site of the Y chromosome is associated with essential hypertension in Chinese Han people.

ABSTRACT: To investigate the chronic efficacy of low-dose hydrochlorothiazide (HCTZ) in patients with mild-to-moderate hypertension.
After a 2-weeks placebo run-in period, 232 patients with mild or moderate hypertension were recruited and received HCTZ (12.5 mg once daily) therapy for one year. Patient compliance and blood pressure were monitored and serum BUN, Cr, glucose, electrolytes, and lipids were measured before, 6 weeks and 1 year after treatment.
(1) Reduction of SBP, DBP and MAP were more significantly at 1 year [(10.45 +/- 17.28) mm Hg, (8.45 +/- 11.06) mm Hg, (9.12 +/- 10.88) mm Hg] than that at 6 weeks post therapy [(6.01 +/- 16.05) mm Hg, (2.90 +/- 10.33) mm Hg, (3.94 +/- 10.68) mm Hg, all P < 0.05]. Blood pressure were reduced to normal in 35.1% patients at 1 year and in 20.3% patients at 6 weeks (P < 0.05). (2) No patient developed diabetes mellitus or hypokalemia during therapy while the serum uric acid at 1 year post therapy was significantly higher than that at before therapy (P < 0.05).
The study indicates that low dose HCTZ is an effective and safe antihypertensive agent for patients with mild-to-moderate hypertension and uric acid changes during therapy need to be monitored.

ABSTRACT: Since males are at higher risk of cardiovascular diseases than females, the aim of the study was to examine whether there is an association between BP and a polymorphic Hind III biallelic marker in nonrecombining region of Y chromosome in essential hypertension in Tangshan district in China.
In the study, 225 patients with essential hypertension and 187 healthy people were enrolled into this study as control group. DNA was extracted from white blood cell. Segments of polymorphic Hind III restriction site of the Y chromosome were amplified from DNA by polymerase chain reaction (PCR). PCR products were restricted with 10 U of Hind III for a night at 37 degrees C. The digested products were subjected to electrophoresis in 3% agarose gels, and stained with ethidium bromide.
We amplified 178 controls (95.2%) and 216 essential hypertensive patients (96.0%) successfully. Hind III(-) genotype was found in 45.8% of the men in essential hypertension and in 32.0% of the men in the controlled group. The Hind III(-) genotype was significantly higher than that in the controls (chi2 = 7.782, P = 0.007). However, the Hind III(+) genotype was lower in SBP (133.16 mm Hg +/- 21.60 mm Hg vs. 143.58 mm Hg +/- 24.16 mm Hg, P < 0.001), DBP (82.82 mm Hg +/- 11.72 mm Hg vs. 86.82 mm Hg +/- 12.65 mm Hg, P = 0.001), pulse pressure (50.34 mm Hg +/- 14.31 mm Hg vs. 56.76 mm Hg +/- 14.20 mm Hg, P < 0.001) and mean arterial pressure (99.59 mm Hg +/- 14.19 mm Hg vs. 105.74 mm Hg +/- 15.31 mm Hg, P < 0.001) than the Hind III(-) genotype.
Polymorphic Hind III restriction site of the Y chromosome seemed to be associated with essential hypertension in Tangshan district in China.

ABSTRACT: To explore the association between G614T single nuclear polymorphism (SNP) of the alpha-adducin gene and the antihypertensive effect of hydrochlorothiazide (HCTZ) in essential hypertensive (EH) patients.
Eight hundred twenty nine EH patients were given 12.5 mg HCTZ/d for six weeks. Alpha-adducin gene G614T SNP in the tenth exon was determined by PCR-RFLP in 754 patients with complete records. All the patients were grouped according to TT, GT and GG genotypes.
After 6 weeks of HCTZ treatment, the decreases in DBP and MAP of patients carrying 614T allele of alpha-adducin were significantly greater than that of those carrying GG homozygotes (P < 0.05). The decreases in SBP and MAP were significantly greater in patients with the TT genotype as compared with GT or GG genotype (P < 0.05). The effective rate of BP fall by HCTZ was higher in patients with TT genotype than those with GT or GG genotype (P < 0.05). Multivariate stepwise regression analysis showed that the TT genotype and the baseline SBP were the two major predictors affecting the decrease in SBP.
The present study suggests that the alpha-adducin G614T polymorphism is associated with the antihypertensive effect of HCTZ, which is more effective in patients with TT genotype.
