Objective: In this paper, we will discuss if the CETP polymorphism contributes to the centenarians in Hainan island.
Methods: We tested the TaqIB and I405V polymorphisms of CETP gene among 276 centenarians and 301 matched healthy individuals by AS-PCR and analyzed the data with SPSS software package (Version 19.0).
Results: Our data indicated that allele B1 and V have the significant differences between centenarians and healthy control groups with P < 0.001. Further analysis implied that genotypes B1B1 (P < 0.001, OR = 0.148, 95% CI = 0.095-0.230) and VV (P < 0.001 and OR = 0.353, 95% CI = 0.237-0.525) were significantly different between centenarians and matched controls. The combination of B and V, such as B1B1-II (P < 0.001, OR = 0.128, 95% CI = 0.049-0.329), B1B1-IV (P < 0.001, OR = 0.115, 95% CI = 0.056-0.237), B1B2-VV (P < 0.05, OR = 0.534, 95% CI = 0.310-0.920), and B2B2-VV (P < 0.001, OR = 0.198, 95% CI = 0.086-0.453) have significant differences between centenarians and matched healthy individuals from Hainan.
Conclusion: Our results implied that allele B1B1 and VV, as well as the combination B1B1-II, B1B1-IV, B1B2-VV and B2B2-VV may contribute to the longevity in centenarians of Hainan, south of China.

Mediating role of inflammatory indicators in the association between sleep status and blood pressure in centenarians: evidence from China Hainan Centenarian Cohort Study.
J Geriatr Cardiol
September 2024
Department of Disease Prevention and Control, First Medical Center, Chinese PLA General Hospital, Beijing, China.
Article Synopsis
- - The study investigates the relationship between sleep quality and blood pressure among centenarians in Hainan, particularly looking at how inflammatory indicators may play a role in this connection.
- - Among 967 centenarians analyzed, 71.4% were found to have hypertension, with those experiencing poor sleep quality having a 43% higher risk of developing high blood pressure.
- - The research identifies specific inflammatory markers such as complement C3 and lymphocyte count as mediators in the relationship between sleep quality and blood pressure, highlighting that both inadequate and excessive sleep durations are linked to higher pulse pressure.

Background: We investigated the associations between IgM, IgG, IgA, and IgE levels and all-cause mortality risk in Chinese centenarians.
Methods: All participants were from the China Hainan Centenarian Cohort Study. Eligible participants were divided into quartiles based on their IgM, IgG, IgA, and IgE levels.

Department of Cardiology, Hainan Geriatric Disease Clinical Medical Research Center, Hainan Branch of China Geriatric Disease Clinical Research Center, Hainan Hospital of Chinese People's Liberation Army General Hospital, Sanya, China.
Background: Sarcopenia is an aging-related disorder characterized by a loss of muscle mass and function. Calf circumference (CC) is a useful surrogate marker of muscle mass and function. This prospective study was designed to investigate the association between CC and all-cause mortality during a follow-up for 5 years in the Chinese centenarians.

Article Synopsis
- In 2023, there were about 110,000 people over 100 years old in China, highlighting the importance of studying treatment options like Paxlovid for centenarians with COVID-19.
- A 103-year-old woman with mild COVID-19 and kidney issues was treated with Paxlovid; despite complications like lung infection and heart failure, her condition improved after additional treatment and supportive care.
- The case indicates that Paxlovid can be administered carefully to elderly patients with kidney problems, and suggests considering multiple treatment courses for those with ongoing positive COVID-19 tests.

Article Synopsis
- This study examined how sleep duration and quality impact overall mortality among centenarians in Hainan, China, using data from a specific cohort study.
- A total of 994 centenarians were analyzed, revealing that while most slept around 8 hours at night, those who took more than 2 hours of daytime sleep had a significantly increased risk of death, particularly among males.
- The findings suggest that excessive sleep duration correlates with higher mortality risk, with a notable threshold at 9 hours, and highlight important sleep patterns in the aging population that may inform future health strategies.
