Effect of Population Factors on China＇s Housing Market

The population factors have an important influence on the housing market. Based on forecasting the change of population quantity, family size, age composition, and population migration, this paper estimates and analyzes the future demand for residence in China and its purpose is to provide a guide for the residential construction by the supply-demand rule.

Serum lipid levels and their risk factors in theGuangxi Mu Lao Zu population

Objectives Mu Lao Zu population.Methods A total of 1055 subjects of Mu Lao Zu were studied by a stratified randomized cluster sampling.Blood pressure,body height, body weight,waist circumference and serum lipid and apolipoprotein(Apo) levels were measured.The data were compared with those in 969 subjects of Han Chinese from the same region.In order to evaluate the association of hyperlipidemia with nine possible riks factors,multivariate logistic regression analysis was also performed in the combined population of Mu Lao Zu and Han,Mu Lao Zu,and Han;respectively. Results The levels of total cholesterol,triglyceride, low-density lipoprotein cholesterol and ApoB in Mu Lao Zu were significantly higher than those in Han(P【0.05-0.001); but the levels of high-density lipoprotein cholesterol,ApoA1 and ApoA1/Apo were significantly lower than those in Han (P【0.001 ).The prevalence of hyperlipidemia and Hypercholesterolemia was also significantly higher in Mu Lao Zu than in Han(53.0%vs.46.1%,P【0.001) and(44.5%vs. 37.5%,P【0.001).There was no difference in the prevalence of hypertriglyceridemia between the both ethnic groups (22.8%vs.19.4%,P】0.05).Hyperlipidemia was positively correlated with age,BMI,and systolic blood pressureMu Lao Zu(P【0.05),whereas it was positively correlated with BMI and hypertension in Han(P【0.05 for each).Conclusions The serum lipid profiles,the prevalence of hyperlipidemia and the risk factors are different between the Mu Lao Zu and Han populations.The differences in serum lipid profiles between the two ethnic groups might result from different dietary habit,life style,as well as genetic factors,in ? To determine the serum lipid levels and their risk factors in the Guangxi.

NO ASSOCIATION BETWEEN TUMOR NECROSIS FACTOR ALPHA AND OBSESSIVE COMPULSIVE DISORDER IN CHINESE HAN POPULATION

Objective To investigate association between tumor necrosis factor alpha (TNF-α) and obsessive compulsive disorder (OCD) in Chinese Han population.Methods Plasma concentrations of TNF-α were measured in 61 drug-free patients who fulfilled DSM-Ⅳ criteria for OCD and 93 healthy controls.TNF-α concentrations in blood were determined by enzyme-linked immunosorbent assay (ELISA).Two polymorphisms of TNF-α gene were investigated in the same patients and healthy controls:-308 G/A and-238 G/A.The allelic and genotypic frequencies of these polymorphisms were examined by using DNA sequencing method.Results Plasma levels of TNF-α did not differ between patients and controls (P=0.292).No significant results were observed for any of the alleles at the-308 G/A or-238 G/A polymorphism of the TNF-α gene.Finally a haplotype consisting of genotypes of these two markers was also examined.No association was observed for any haplotype (P=0.108).Conclusion No significant differences were observed between patients and controls in plasma levels of TNF-α.There is no association between the-308 G/A and-238 G/A TNF-α gene polymorphisms and OCD in our Chinese samples.However,the results need to be replicated in larger samples.

Blood pressure differences in people with various individual characteristics in Guangdong Province

Objective To study the differences in blood pressure (BP) levels and the main factors raising BP among the population in Guangdong Province. Methods The data analyzed stem from the sampling survey of hypertension in Guangdong Province in 1991, covering 42, 894 subjects over 15 years old. Individual characteristics included age, sex, occupation, education, smoking, alcohol drinking and body mass index (BMI) . Results Systolic and diastolic BP increased with age. The hypertension prevalence rate in male is higher than in female. The age - adjusted prevalence rate in office personnel is the highest (12.9 % ) among all occupations. It was increased with education level and BMI (in people educated at university and over is 13. 1 % ), and higher in smokers and alcohol-drinkers than non-smokers and non -alcohol-drinkers. Conclusions Age, occupation, education, smoking, alcohol drinking and BMI all effect BP. These risk factors should be reduced in the Guangdong population.

Relationship between hypertriglyceridemic-waist phenotype and clustering of cardiovascular risk factors in middle and aged population

Objective To explore the relationship between hypertriglyceridemic-waist(HTWC)phenotype and clustering of cardiovascular risk factors in middle and aged population.Methods A community-based cross-sectional survey was conducted in 5 communities of Chengdu city from 2013-10 to 2014-05 and 1004 subjects from(40-79)years of age were investigated.HTWC was de-
