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.

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.

Objective: To analyze the prevalence trends and related factors of hypertension patients complicating with dyslipidemia in community. Methods: This was a cross-sectional survey, patients with hypertension were selected from the different communities of Guangdong province in 2013 and 2018 respectively. General clinical characteristics, including demographic information, past history, family history, and medication history, were collected. Dyslipidemia was defined as follows: at least 1 item elevation of total cholesterol (TC)≥5.2 mmol/L, triglyceride (TG) ≥1.7 mmol/L, low-density lipoprotein cholesterol (LDL-C)≥3.4 mmol/L, or reduced high-density lipoprotein cholesterol (HDL-C)<1.0 mmol/L. The incidence of dyslipidemia was standardized based on the 2010 China Census data, and further subgroup analysis was performed according to age (<50, 50-60, ≥60 years old) and sex (male, female). Multivariate logistic regression was used to analyze the related factors of dyslipidemia. Results: In 2013 and 2018, 7 866 (4 148 (52.7%) females, with the age of (62.4±13.6) years) and 11 611 (6 692 (57.6%) females, with the age of (58.2±9.3)years) patients with hypertension were enrolled for data analysis, respectively. In 2013, the total prevalence rate of dyslipidemia in patients with hypertension in the community of Guangdong province was 56.3%, among which the prevalence rates of hypercholesterolemia, hypertriglyceridemia, high LDL-Cemia, and low HDL-Cemia were 17.1. %, 21.3%, 2.3% and 24.4%, respectively. The total prevalence of dyslipidemia in patients with hypertension in the community of Guangdong in 2018 was 47.3%, prevalence of hypercholesterolemia, hypertriglyceridemia, high LDL-Cemia and low HDL-Cemia was 14.1%, 20.3%, 12.0% and 19.4%, respectively. Subgroup analysis showed that the total prevalence of dyslipidemia in male patients with hypertension in the community of Guangdong in 2013 and 2018 was 59.0% and 50.7%, respectively, among which hypercholesterolemia was 13.8% and 8.0%, and hypertriglyceridemia was 22.3%, 20.9%, high LDL-Cemia was 1.7%, 8.1%, low HDL-Cemia was 32.9%, 30.3%, respectively. In 2013 and 2018, the total prevalence of dyslipidemia in female patients with hypertension in the community of Guangdong province was 53.9% and 44.8%, among which prevalence of hypercholesterolemia was 20.5% and 18.5%, hypertriglyceridemia was 20.4% and 19.8%, and high LDL-Cemia was 2.7% and 14.9%, and hypo-HDL-Cemia was 16.8% and 11.3%, respectively. Age subgroup analysis showed that the prevalence of dyslipidemia among hypertensive patients aged<50, 50-60, and ≥60 years in Guangdong community in 2013 were 60.1%, 60.6%, and 53.7%, respectively; and 46.2%, 49.3% and 46.5% in 2018, respectively. Multivariate logistic regression analysis showed that women (OR=0.860,95%CI 0.761-0.973,P=0.017), obese (OR=2.295,95%CI 2.007-2.624,P<0.001), diabetes (OR=1.314,95%CI 1.090-1.583,P=0.004), stroke (OR=1.894,95%CI 1.227-2.924,P=0.004) and the level of fasting blood glucose (OR=1.105,95%CI 1.066-1.146,P<0.001) were independently related with the occurrence of dyslipidemia. Conclusions: The prevalence of dyslipidemia in patients with hypertension in the communities of Guangdong province is relatively high, and the prevalence differs in sex and age. Between 2013 and 2018, the total prevalence of dyslipidemia, hyper-TCemia, and hypo-HDL-Cemia in hypertensive patients shows a downward trend. The prevalence of hyper-TGemia remains unchanged, but the prevalence of high LDL-C shows an upward trend. Several factors are related to the prevalence of dislipidemia in hypertension patients in Guandong community.

OBJECTIVE:
To investigate the abnormality and distribution of plasma cholesterol levels in single-center hospitalized children.
METHODS:
The blood lipid levels of children aged 2-18 years who had blood lipid test results in Peking University First Hospital from June 2016 to June 2019 were etrospectively analyzed. Cholesterol oxidase method was used for total cholesterol, and high-density lipoprotein cholesterol and low-density lipoprotein cholesterol were detected by clearance method. The counting data were compared with chi-square test.
RESULTS:
The survey had involved 11 829 children (7 087 were boys and 4 742 were girls). 1 822 (15.4%) children were with elevated total cholesterol, 1 371 (11.6%) children with elevated low-density lipoprotein cholesterol, and 2 798 (23.7%) children with high-density lipoprotein cholesterol reduction. The total number of the children with abnormal cholesterol levels was 4 427 (37.4%). Among the 7 835 children who visited hospital due to the disease not commonly inducing dyslipidemia, 731 (9.3%) had elevated TC, 561 (7.2%) had elevated LDL-C, 1 886 (24.1%) had decreased HDL-C, and 2 576 (32.9%) had abnormal cholesterol levels. Among the children with different diseases, the difference in the incidence of abnormal cholesterol was statistically significant. The top three main groups of the children with increased total cholesterol and low-density lipoprotein cholesterol were "dyslipidemia", "urinary tract disease", and "nutritional disease"; The top three main groups of the children with reduced high-density lipoprotein cholesterol were "respiratory diseases", "dyslipidemia", "hematological diseases and malignant tumors". Among the 1 257 blood li-pid test results sent by other departments, 300 cases had abnormal cholesterol levels (23.8%). Among them, there were 70 children with hypercholesterolemia (5.6%), 44 children with increased low-density lipoprotein cholesterol (3.5%), and 224 children with reduced high-density lipoprotein cholesterol (17.8%). There were 365 (4.6%) children with low-density lipoprotein cholesterol ≥140 mg/dL (3.6 mmol/L) who needed to further exclude familiar hypercholesterolemia among the children who visited hospitals due to the disease not commonly inducing dyslipidemia.
CONCLUSION
Children in hospitals have a high incidence of cholesterol abnormalities. Doctors need to pay more attention to the cholesterol diagnosis and management regardless of the discipline, which not only helps to control secondary hypercholesterolemia, but also provides the possibility of detecting familial hypercholesterolemia in time.

Objective: To understand the relationship between secondhand smoke exposure and dyslipidemia among adults in Beijing and to provide a scientific basis for relevant intervention. Methods: Data were from Beijing Adult Non-communicable and Chronic Diseases and Risk Factors Surveillance Program in 2017. A total of 13 240 respondents were selected by multistage cluster stratified sampling method. The monitoring contents include a questionnaire survey, physical measurement, collection of fasting venous blood, and determination of related biochemical indicators. SPSS 20.0 software was used for the chi-square test and multivariate logistic regression analysis. Results: The prevalence of total dyslipidemia (39.27%), hypertriglyceridemia (22.61%), and high LDL-C (6.03%) were the highest among those exposed to daily secondhand smoke. Among the male respondents, the prevalence of total dyslipidemia (44.42%) and hypertriglyceridemia (26.12%) were the highest among those exposed to secondhand smoke daily. Multivariate logistic regression analysis after adjustment for confounding factors showed that compared with no exposure to secondhand smoke, the population with an average exposure frequency of 1-3 days per week had the highest risk of total dyslipidemia (OR=1.276, 95%CI: 1.023-1.591). Among the patients with hypertriglyceridemia, those exposed to secondhand smoke daily had the highest risk (OR=1.356, 95%CI: 1.107-1.661). Among the male respondents, those exposed to secondhand smoke for 1-3 days per week had a higher risk of total dyslipidemia (OR=1.366, 95%CI: 1.019-1.831), and the highest risk of hypertriglyceridemia (OR=1.377, 95%CI: 1.058-1.793). There was no significant correlation between the frequency of secondhand smoke exposure and the risk of dyslipidemia among female respondents. Conclusions: Secondhand smoke exposure in Beijing adults, especially men, will increase the risk of total dyslipidemia, especially hyperlipidemia. Improving personal health awareness and minimizing or avoiding exposure to secondhand smoke is necessary.

OBJECTIVETo understand the prevalence and control of several common chronic disease in Beijing adults.
METHODS16,658 adult residents were randomly selected with stratified multi-stage cluster sampling method. Each participant was invited to receive a set of standardized questionnaire, physical examinations and laboratory tests.
RESULTSData showed that the prevalence, awareness, treatment and the rate of control on hypertension among the adults in Beijing were 29.1%, 49.3%, 42.3% and 10.6% respectively. The counterparts of diabetes mellitus were 8.8%, 56.7%, 50.0% and 15.0%. The four corresponding figures for dyslipidemia were 33.2%, 31.1%, 13.0% and 4.3%, respectively. 22.9% of the Beijing adults had metabolic syndrome including 8.1 per thousand suffering from myocardial infarction and 18.4 per thousand from stroke. Except for diabetes, all the chronic diseases had higher prevalence rate in rural area than in urban area, according to the findings under our study. Postmenopausal women were more susceptible to chronic disease than men.
CONCLUSIONThe prevalence rate of chronic disease in Beijing was still high. The prevalence rate in rural area had exceeded the level in urban area. Adjustment and attention should be made according to the prevalence features and weakness existed in present chronic disease control strategy.
