Objective To investigate the effect of Helicobacter pylori (Hp) infection on plasma lpid and high sensitive C reactive protein (hs-CRP) levels in patients with cerebral infarction, and explore the pathogenesy. Methods Seventy-nine cerebral infarction patients without nearly inflammatory reaction disease were recruited. Hp was detected by breath test,the patients were divided into infection-negative group (15 cases), light infection group (29 cases) and severe infection group(35 cases) according to the results,the last two groups were as infection-positive group. The plasma lipid and hs-CRP levels were exanined.Results Compared with infection-negative group,the total cholesterol,low density lipoprotein,hs-CRP levels increased obviously in infecton-positive group (P ＜ 0.05). The level of hs-CRP in severe infection group was higher than that in light infection group [(10.21 ±4.98) mg/L vs. (5.81 ±4.21) mg/L](P=0.001 ). Conclusions Hp infection may increase vascular inflammatory reaction through lipid metabolic disturbance. The cerebral infarction with higher Hp infection, and with the degree of infection increased, the risk is also increased accordingly.

Objective: To establish a hydrogen peroxide (H₂O₂) induced injury model of pulmonary artery endothelial cells (PAECs) and explore the molecular mechanisms of oxidative stress on the structure and function of PAECs in this model. Methods: Human PAECs were treated with H₂O₂ at different concentrations (25, 50, 100, 200, 400, 800, 1 600, 3 200, 6 400 μmol/L) for 4 and 24 h, respectively. The PAECs survival curve was obtained according to the cell viability measured by CCK-8 assay. The cell apoptosis of PAECs was detected by flow cytometry. The reactive oxygen species (ROS) generation and mitochondrial activity were measured using small molecule fluorescent probes. Proteins were extracted and the phosphorylation levels of signal molecules in PAECs were detected by Western blot assays. Results: (1) The effect of H₂O₂ at various concentrations on cell viability of PAECs: cell viability of PAECs decreased in proportion to increasing concentration of H₂O₂ after incubation for 4 h. The half maximal inhibitory concentration (IC₅₀) of PAECs exposed to H₂O₂ for 4 and 24 h were 397.00 and 488.77 μmol/L, respectively. (2) The effect of H₂O₂ on cell apoptosis of PAECs: After H₂O₂ incubation for 4 h, proportions of PAECs at late-apoptosis ((22.58±3.69) %) and necrotic stage( (11.86±4.27)%) were significantly higher than those of control PAECs at late-apoptosis stage( (3.41±1.44)%, P<0.01) and at necrotic stage ((1.94±1.15) % , P<0.05). The survival rate of PAECs post H₂O₂ was dramatically lower than that of control PAECs ((7.98±3.21)% vs. (48.89±8.08)%, P<0.01). However, there is no statistical difference between both groups regarding to the early apoptosis. (3) The effect of H₂O₂ on mitochondrial activity and ROS production of PAECs: the mitochondrial activity and ROS generation of PAECs treated by H₂O₂ were significantly increased compared to those in control PAECs (P<0.01). (4) The effect of H₂O₂ on signaling molecules in PAECs: there was a significant increase in phosphorylation level of Akt in PAECs incubated with H₂O₂ for 30 minutes compared to that in control PAECs (P<0.01), while there was no significant difference in levels of Akt between H₂O₂ treated PAECs and control PAECs. Phosphorylation level of JNK as well as p38 were also significantly upregulated in H₂O₂ treated PAECs (P<0.01). Conclusion H₂O₂ at the concentration of 400 μmol/L could induce human PAECs injuries via the regulation of Akt and MAPK signaling pathways.

Objective:To investigate the distribution characteristics of cognition-related lifestyles of elderly in communities and explore the integrated effects on early cognitive decline.Methods:The participants were from the Project of Prevention and Intervention of Neurodegenerative Disease for Elderly in China. A total of 2 537 older adults aged ≥60 years without dementia in the 2015 baseline survey and the 2017 follow-up survey were included. The information about their cognition-related lifestyles, including physical exercise, social interaction, leisure activity, sleep quality, smoking status, and alcohol consumption, were collected through questionnaire survey and the integrated scores were calculated. Multivariate logistic regression analysis was used to assess the association between integrated cognition-related lifestyle score and early cognitive decline.Results:In the 2 537 older adults surveyed, 28.7% had score of 5-6, while only 4.8% had high scores for all 6 healthy lifestyles. Significant differences in healthy lifestyle factor distributions were observed between men and women. Multivariate logistic regression model showed that the risks for early cognitive decline in the older adults who had lifestyle score of 4 and 5-6 were lower than that in those with lifestyle score of 0-3 ( OR=0.683, 95% CI: 0.457-1.019; OR=0.623, 95% CI: 0.398-0.976; trend P=0.030). In the women, the risks for early cognitive decline was lower in groups with score of 4 and 5-6 than in group with score of 0-3 ( OR=0.491, 95% CI: 0.297-0.812; OR=0.556, 95% CI: 0.332-0.929; trend P=0.024). Conclusion:Cognition-related healthy lifestyles are associated with significantly lower risk for early cognitive decline in the elderly, especially in women.

Centenarians are known as the "model population" in the study of healthy aging. Understanding their characteristics of health and longevity and its related influencing factors would facilitate the exploration of the possible path to achieve health and longevity under the background of population aging in China. In recent years, the population based observational studies, including China Hainan Centenarian Cohort Study (CHCCS), have found the main health characteristics of centenarians and their relationship with quality of life. This paper summarizes the relevant research results from CHCCS in recent years, and compare them with the results of similar domestic studies. The main health indicators include blood pressure, blood lipid, blood glucose, hemoglobin, body measurement and renal function. The health outcomes including diet, nutrition, health-related quality of life, activities of daily living, geriatric syndrome. The results are expected to provide epidemiological evidence for the development of healthy aging policies.
