Objective: To investigate the prevalence and influencing factors of dyslipidemia among residents in Changzhou City, Jiangsu Province, so as to provide insights into improving prevention and control strategies of dyslipidemia. Methods: Permanent residents aged 35 to 75 years were recruited based on the Early Screening and Comprehensive Intervention Project for High-risk Populations of Cardiovascular Disease in Changzhou City from 2016 to 2023. Demographic information, body mass index (BMI), total cholesterol (TC), triglycerides (TG), low-density lipoprotein cholesterol (LDL-C) and high-density lipoprotein cholesterol (HDL-C) were investigated through questionnaire surveys, physical examinations and laboratory tests, and the prevalence of dyslipidemia were analyzed. Factors affecting dyslipidemia were identified using a multivariable logistic regression model. Results: A total of 22 447 residents were surveyed, including 9 142 males (40.73%) and 13 305 females (59.27%), and had a median age of 57.00 (interquartile range, 18.00) years. There were 7 535 cases of dyslipidemia, with a prevalence rate of 33.57%. The prevalence rates of low HDL-C, high TG, high TC, and high LDL-C were 22.27%, 15.89%, 4.06% and 2.27%, respectively. Multivariable logistic regression analysis showed that the residents who were male (OR=1.780, 95%CI: 1.645-1.924), had more than 50 000 yuan of annual household income (OR=1.215, 95%CI: 1.142-1.293), had higher educational level (junior high school/senior high school/technical secondary school, OR=1.138, 95%CI: 1.047-1.237; junior college and above, OR=1.232, 95%CI: 1.095-1.386), smoked frequently (OR=1.504, 95%CI: 1.369-1.653), were overweight (OR=1.763, 95%CI: 1.650-1.885) or obese (OR=2.351, 95%CI: 2.149-2.572), had hypertension (OR=1.478, 95%CI: 1.384-1.579) and diabetes (OR=1.706, 95%CI: 1.586-1.835) had a higher risk of dyslipidemia; while the residents who consumed alcohol at 4 times per week and more (OR=0.619, 95%CI: 0.557-0.688) had a lower risk of dyslipidemia. Conclusions The main types of dyslipidemia are low HDL-C and high TG among residents aged 35 years and above in Changzhou City. The prevalence of dyslipidemia is mainly associated with gender, annual household income, educational level, smoking, alcohol consumption, BMI, hypertension and diabetes.

To analyze the genetic characteristics of a polio-I highly variant vaccine recombinant virus in Shandong Province (China) in 2011 and to identify isolates from healthy contacts, two stool specimens from one patient with acute flaccid paralysis (AFP) and 40 stool specimens from his contacts were collected for virus isolation. The complete genome of poliovirus and VP1 coding region of the non-polio enterovirus were sequenced. Homologous comparison and phylogenetic analyses based on VP1 sequences were undertaken among coxsackievirus (CV) B1, CV-B3 isolates, and those in GenBank. One poliovirus (P1/11186), CV-A4 and CV-A8 were isolated from the AFP patient; one CV-A2, Echovirus 3 (E-3), E-12 and E-14, ten CV-B1, and five CV-B3 strains were isolated from his contacts. These results led us to believe that there may be a human enterovirus epidemic in this area, and that surveillance must be enhanced. P1/11186 was a type-1 vaccine-related poliovirus; it combined with type-2 and type-3 polioviruses in 2A and 3A regions, respectively. There were 25 nucleotide mutations with 9 amino-acid alterations in the entire genome. There were 8 nucleotide mutations with 5 amino-acid alterations in the VP1 region compared with the corresponding Sabin strains. Homology analyses suggested that the ten CV-B1 isolates had 97.0%-100% nucleotide and 98.9%-100% amino-acid identities with each other, as well as 92.6%-100% nucleotide and 99.2%-100% amino-acid identities among the five CV-B3 isolates. Phylogenetic analyses on the complete sequences of VP1 among CV-B1 and CV-B3 isolates showed that Shandong strains, together with strains from other provinces in China, had a close relationship and belonged to the same group.
