OBJECTIVETo investigate the plasma lipid levels in a national representative sample of subjects and to determine the prevalence of dyslipidemia in the Chinese population.

METHODSPlasma lipid profile was analyzed using the data obtained during the Chinese national nutrition and health survey (CNHS) in 2002 which involved 14 252 participants at the age of 18 years or older.

RESULTSThe mean levels of total cholesterol (TC), triglyceride (TG) and high density lipoprotein cholesterol (HDL-C) in the participants were 3.81 mmol/L, 1.10 mmol/L, and 1.30 mmol/L, respectively. In the groups of participants at the age of 18-44 years, 45-59 years, and over 60 years the mean TC level was 3.70 mmol/L, 4.09 mmol/L and 4.21 mmol/L, respectively, and the mean TG level was 07 mmol/L, 1.21 mmol/L, 1.20 mmol/L, 1.29 mmol/L, 1.33 mmol/L, and 1.33 mmol/L, respectively. The prevalence of dyslipidemia in Chinese adults was 18.6% and 22.2% in males and 15.9% in females. Dyslipidemia prevalence was higher in urban districts than in rural areas (21.0% vs. 17.7%). The prevalence of hypercholesterolemia, hypertriglyceridemia, and low HDL cholesterol was 2.9%, 11.9%, and 7.4% respectively among the participants.

CONCLUSIONDyslipidemia has become one of the important health risk factors in the Chinese population. There is no significantly difference in the prevalence of dyslipidemia between the groups of participants at the age of 45-59 years and over 60 years. This study provides important lipid profile data for policy making and guideline development for the prevention of dyslipidemia in the Chinese population.

OBJECTIVETo investigate the relationship between SNPs reported in previous studies and the blood lipid level in the Tibetan population.

METHODSRandom cluster sampling was employed in 5 areas (Lhasa, Shigatse, Shannan, Nagqu, and Nyingchi). The levels of cholesterol (TC), triglyceride (TG), high-density lipoprotein cholesterol (HDL-C), and low-density lipoprotein cholesterol (LDL-C) from blood samples were determined and DNA was extracted for genotyping and statistical analyses.

RESULTSAmong 1 318 subjects aged >18 years enrolled in this study, 367 had dyslipidemia with a prevalence of 27.8%, of whom dyslipidemia males accounted for 33.1% and dyslipidemia females -24.5%. Results of the correlation analysis between all SNPs and TG showed that the SNPs of rs714052 and rs964184 were related to the serum TG level. Subjects with rs714052 CC genotype had the lowest TG level, and the highest TG level was found in those with rs714052 TT genotype. The serum TG level in individuals with TC genotype lied in between the above two population groups. Subjects with rs964184 CC genotype had the lowest TG level, and the highest serum TG level was noted in those with rs964184 GG genotype.

CONCLUSIONSeveral SNPs were found to be related to the serum TG level in the Tibetan population. The APOA5 gene and MLXIPL gene may be closely associated with the serum TG level in this ethnic population group.

PURPOSE: High-Sensitivity C-reactive protein(hs-CRP) has been recognized as a very useful and sensitive predictor of the future risk of myocardial infarction. But the clinical significance of hs-CRP in children remains uncertain. To confirm the existence of obesity-induced vascular inflammation and the association between metabolic syndromes and elevation of CRP in children, we investigated the relationship among CRP, obesity, blood pressure(BP), and serum lipids in schoolboys. METHODS: Twenty-eight obese(BMI 29.61+/-3.29 kg/m2) and 93 non-obese(BMI 18.99+/-2.21 kg/m2) boys aged 14 years were examined. Serum CRP levels was measured by the high sensitive latex turbidimetric immunoassay and subjects with CRP levels below 0.3 mg/dL were adopted to avoid the influence of acute infection. RESULTS: Obese children had significantly higher hs-CRP levels than their non-obese group(0.104+/-0.075 vs. 0.054+/-0.005 mg/dL). In the obese group, BMI, systolic blood pressure, diastolic blood pressure, apolipoprotein B, atherogenic index, and triglyceride were significantly higher than in non-obese. The BMI, diastolic blood pressure, apolipoprotein E, atherognic index, and triglyceride showed positive correlation with log CRP by simple regression. Multiple regression analysis indicated that BMI and apolipoprotein E were strongly related to CRP. CONCLUSION: This study revealed that obese children tended to have higher levels of serum hs-CRP, BP elevation and dyslipidemia than the control group and that BMI and apolipoprotein E were strongly related to CRP. These results indicate that obesity related metabolic syndrome can be developed in children.

OBJECTIVE: To evaluate the effects of 12 weeks high intensity interval training(HIIT) on serum lipids profile in patients with dyslipidemia of different apolipoprotein E(ApoE) genotypes. METHODS: Eighty-eight patients with dyslipidemia were screened by fasting blood lipid as subjects. Apolipoprotein E genotypes were detected in oral mucosa of subjects. Serum lipids before and after 12 weeks high intensity interval training were measured to analysis the effect of high intensity interval training on serum lipids. RESULTS: Five genotypes were detected in 88 cases of dyslipidemia. The distributions were ApoE3/3＞ApoE3/4＞ApoE2/3＞ApoE2/2＞ApoE2/4,and allele ε3＞ε2=ε4. Before exercise intervention, the level of total cholesterol in patients with ε4 allele was significant higher than those in patients with ε2 and ε3 (P＜0.01), low density lipoprotein cholesterol in patients with ε4 was significant higher than that of patients with ε2 (P＜0.05), and the other indexes had no significant difference among the groups (P＞ 0.05). After 12 weeks high intensity interval training, the levels of total cholesterol, triglyceride and low density lipoprotein cholesterol were decreased significantly ,while the level of high density lipoprotein cholesterol was increased in those patients with ε3 genotype. For those individuals with ε4 genotype , their serum levels of total cholesterol and low density lipoprotein cholesterol were reduced after 12 weeks high intensity interval training , but there was no changes in serum levels of triglyceride and high density lipoprotein cholesterol. For those individuals with ε2 genotype, there was no significant improvement in serum lipids after 12 weeks high intensity interval training interventions. CONCLUSION The polymorphisms of apolipoprotein E gene resulted in different effects of exercise interventions on serum lipids of dyslipidemia. Twelve weeks high intensity interval training can be used as an intervention method to regulate serum lipids of dyslipidemia with ε3 and ε4 alleles.

Diabetes mellitus is associated with a high frequency of complications related to cardiovascular disease as well as microvascular complications such as nephropathy, retinopathy, and neuropathy. Prevention of these vascular complications is the main issue for diabetic patients. Hyperglycemia, hypertension, and dyslipidemia are well-known risk factors for complications in diabetic patients. Moreover, these chronic conditions are often seen in many diabetic patients. So, multifactorial interventions are needed to manage these risk factors and prevent diabetic complications. However, there is still a debate about the optimal level required for glycemic control, the appropriate blood pressure target, and dyslipidemia management. Although many countries have written their own guidelines, there are some discrepancies between these different guidelines. Recently, the Korean Diabetic Association issued new guidelines for Korean diabetic patients. Here, I will introduce these new guidelines and discuss the optimal management of risk factors such as hyperglycemia, hypertension, and dyslipidemia in diabetic patients.

This study investigated the relationship between serum thyrotrophin levels and dyslipidemia in subclinical hypothyroid and euthyroid subjects. A total of 110 subjects with subclinical hypothyroidism and 1,240 euthyroid subjects enrolled in this study. Patients with subclinical hypothyroidism had significantly lower high density lipoprotein cholesterol (HDL-C) levels than those who were euthyroid. The lipid profiles were each categorized and mean thyrotrophin levels were higher in subjects in the dyslipidemia subclasses than subjects in the normal subclasses. Thyrotrophin was positively associated with serum triglyceride and negatively associated with serum HDL-C in women. Thyrotrophin was also positively associated with total cholesterol (TC) in the overweight population along with TC and LDL-C in overweight women. In the euthyroid population, thyrotrophin was positively associated with TC in the overweight population. In conclusion, serum thyrotrophin was correlated with dyslipidemia in subclinical hypothyroid and euthyroid subjects; the correlation was independent of insulin sensitivity.

INTRODUCTIONGamma-glutamyltransferase (GGT), bilirubin (Bil) and small dense low-density lipoprotein (sdLDL) particles are each known to be risk markers for cardiometabolic diseases which are characterised by oxidative stress conditions. These markers are connected with the oxidative milieu; however, the association between GGT, Bil, and sdLDL has been hardly examined. This hospital-based study investigated the association between GGT and sdLDL, as well as the association between Bil and sdLDL, in asymptomatic subjects.

MATERIALS AND METHODSCardiometabolic variables, GGT, Bil and the mean LDL particle size were measured in 100 asymptomatic subjects attending a clinic for screening dyslipidaemias (36 men and 64 women, mean age 64 years). Correlation analyses of the association between the mean LDL particle size and other variables, such as GGT and Bil, were performed.

RESULTSThe mean (standard deviation) levels of GGT, Bil, and the mean LDL particle size were found to be 21.7 (8.3) IU/L, 14.0 (4.3) μmol/L, and 26.7 (0.6) nm, respectively. An univariate correlation test showed both a significant inverse correlation between the mean LDL particle size and GGT (r = - 0.33, P <0.01) and a significant positive correlation between the mean LDL particle size and Bil (r = 0.32, P <0.01). A multiple regression analysis revealed similarly significant results of their correlations, independent of the other cardiometabolic variables.

CONCLUSIONThese results suggest that the correlation of GGT and sdLDL, as well as that of Bil and sdLDL, may be cooperatively associated with cardiometabolic processes. Further research is warranted in order to confirm the observed association.

BACKGROUND AND OBJECTIVES: The early morning blood pressure surge (EMBPS) has been reported to be associated with cardiovascular events. The aim of this study was to investigate the relationship between 24-hour ambulatory BP monitoring (ABPM) parameters and conventional cardiovascular risk factors. SUBJECTS AND METHODS: Patients (n=346) never-treated for essential hypertension with no other cardiovascular risk factors, such as diabetes, dyslipidemia, and nephropathy were enrolled. The EMBPS was defined as the early morning systolic BP minus the lowest night systolic BP. We compared the 24-hour ABPM parameters in two groups divided by age (<60 and > or =60 years) and examined the association between the 24-hour ABPM parameters and cardiovascular risk factor. RESULTS: The EMBPS (18+/-14 vs. 24+/-14 mmHg, p=0.002), 24-hour mean blood pressure {MBP; 102+/-9 vs. 105+/-11 mmHg, p=0.044}, and 24-hour mean pulse pressure (PP; 52+/-10 vs. 58+/-11 mmHg, p<0.001) were significantly increased in the elderly subjects compared to the younger subjects. The degree of decrease was less in the elderly subjects (10+/-8 vs. 7+/-10%, p=0.002). Based on multivariate analysis, age was an independent risk factor for the highest quartile of EMBPS (>28 mmHg) after adjusting for gender differences, body mass index, and various 24-hour ABPM parameters (odds ratio, 1.051; 95% confidence interval, 1.028-1.075; p<0.001). CONCLUSION: Age is an independent risk factor for EMBPS in patients with never-treated hypertension. BP control in the early morning period is more important in elderly patients so as to prevent cardiovascular events.

OBJECTIVETo explore the association between dyslipidemia and different subtypes of hypertension among Zhejiang population.

METHODSFrom June to October in 2010, 19 113 local residents aged ≥ 18 years old were selected among 7571 families from fifteen counties in Zhejiang by four stage stratified-random sampling method. A self-designed questionnaire was adopted to collect information on demographic characteristics, physical activity and life style. At the same time, physical examinations including height, weight, blood pressure and blood lipids were carried out.

RESULTSA total of 19 113 participants completed the interviews, physical examinations and collected the blood samples.Excluding those who did not meet the criteria, 14 731 were finally enrolled in the study. The prevalence rates of isolated systolic hypertension (ISH), isolated diastolic hypertension (IDH), systolic and diastolic hypertension (SDH) were 7.16% (1055/14 731, standardized rate:5.46%), 4.60% (677/14 731, standardized rate:4.41%), 7.09% (1045/14 731, standardized rate:5.75%), respectively. Among normal blood pressure group, subjects with normal TC, high TC and abnormal TC were separately 10 571 (88.43%), 1173 (9.81%) and 210 (1.76%); subjects with normal HDL-C and low HDL-C were separately 6885 (57.60%) and 5069 (42.40%); subjects with normal TG, high TG, abnormal TG were separately 9952 (79.91%), 1213 (10.15%) and 1189(9.95%).In ISH group, subjects with normal TC, high TC and abnormal TC were separately 826 (78.29%), 188 (17.82%) and 41 (3.89%); subjects with normal HDL-C and low HDL-C were separately 666(63.13%) and 389 (36.87%); subjects with normal TG, high TG and abnormal TG were separately 737 (69.86%), 150 (14.22%) and 168 (15.92%). Multi factor analysis showed that high TG and abnormal TG were associated with ISH (OR (95%CI):1.43 (1.16-1.76), 1.65 (1.34-2.03) respectively). Among IDH group, subjects with normal TC, high TC, abnormal TC were separately 556(82.13%), 99(14.62%) and 22 (3.25%); subjects with normal HDL-C, low HDL-C were separately 335 (49.48%) and 342 (50.52%); subjects with normal TG, high TG, and abnormal TG separately were 402 (59.38%), 107 (15.81%) and 168 (24.82%). The multi factor analysis showed that high TG and abnormal TG could increase the risk of IDH (OR(95%CI):1.57 (1.24-1.98), 2.18 (1.76-2.70) respectively). Among SDH group, subjects with normal TC, high TC and abnormal TC were 817 (78.18%), 193 (18.47%) and 35 (3.35%); subjects with normal HDL-C and abnormal HDL-C were separately 599 (57.32%) and 446 (42.68%); subjects with normal TG, high TG, abnormal TG were separately 675 (64.59%), 164 (15.69%) and 206 (19.71%). The multi factor analysis showed that high TC, high TG and abnormal TG were also associated with the increased risk of SDH (OR (95%CI):1.38 (1.14-1.67), 1.43(1.18-1.75), 1.73 (1.43-2.10) respectively).

CONCLUSIONDyslipidemia is an important factor of different subtypes of hypertension among Zhejiang population, especially triglycerides. Dyslipidemia screening should be strengthened to reduce the risk of cardiovascular diseases.
