Background Dyslipidemia is the most important and causal independent risk factor for atherosclerotic cardiovascular disease (ASCVD) . The prevalence of dyslipidemia in elderly residents in Guangdong Province is high, and it is urgent to analyze the specific prevalence of dyslipidemia and its influencing factors among the elderly, and to carry out targeted preventive and control measures for dyslipidemia. Objective To investigate the epidemiological status of dyslipidemia and its risk factors among elderly residents included in the national basic public health service in Yuexiu District, Guangzhou. Methods A total of 41 469 elderly residents aged 65 years and above with complete important variables were selected as subjects from the information system of community health service center in Yuexiu District, Guangzhou City in 2020, the 2020 health checkup data was used to describe the epidemiological characteristics of the included patients such as basic information, BMI and blood lipid levels. Restricted cubic spline (RCS) fitting Logistic regression model was used to analyze the relationship between age, BMI and the prevalence of dyslipidemia. Results The prevalence of dyslipidemia in 41 469 elderly residents was 53.65% (22 247/41 469) , with a standardized prevalence of 53.89%. The prevalence of hypercholesterolemia (HTC) , hypertriglyceridemia (HTG) , mixed hyperlipidemia and low high-density lipoprotein cholesterol was 21.43%, 16.50%, 14.51% and 3.80%, with the standardized prevalence of 21.57%, 16.53%, 14.61%, 3.78%, respectively. Multivariate Logistic regression analysis showed that gender, age, education level, exercise status, and BMI were all influencing factors for dyslipidemia in elderly residents, among which female, low age group, and high BMI were risk factors for dyslipidemia in elderly residents (P more...

Aim: The present study aims at preparation of CARP antibody and analysis of CARP expression pattern., Methods: Through bioinformatics analysis the antigenicity of CARP, 279 bp cDNA fragment coding CARP N-terminal 93 amino acid was amplified by RT-PCR from mouse heart RNA, then cloned into pET-28b to construct the prokaryotic expression pET 28b-CARP N93. The plasmid was transformed into E.coli(BL21). The target fusion protein was expressed with induction of IPTG, and purified by affinity chromatography. The antiserum against CARP was obtained from the mice immunized with CARP. CARP expression patterns were examined by Western blot and immunofluorescence., Results: Prepared CARP antibody; CARP specific expression in mouse heart and mainly localized in the nucleus in rat cardiac primary cells., Conclusion: Successfully generated CARP antibody and examined the expression pattern. The present study has laid a foundation for functional study of CARP. more...
