Objective:To analyze the trend of lipid changes in patients and individuals undergoing physical examination at Zhongshan Hospital of Fudan University from 2014 to 2024, providing evidence for the formulation of cardiovascular disease prevention and control strategies.Methods:A total of 2 657 835 individuals (general population) who underwent lipid testing during medical visits or physical examinations at Zhongshan Hospital of Fudan University from January 1, 2014, to December 31, 2024, were selected. Among them, 6 234 individuals who were tested consecutively for 11 years were considered as the fixed population. Lipid levels were analyzed across different genders and age groups. Total cholesterol (TC), triglycerides (TG), low-density lipoprotein cholesterol (LDL-C), and high-density lipoprotein cholesterol (HDL-C) were analyzed. The trends in lipid changes and the abnormal rates of TC (≥5.18 mmol/L) and LDL-C (≥3.40 mmol/L) in both the general and fixed populations were statistically analyzed.Results:The median age of the general population was 53 (41, 63) years, with 1 498 533 males (56.4%); 1 149 662 individuals (43.3%) were from the physical examination group. The median age of the fixed population was 52 (39, 62) years, with 3 262 males (52.3%); 2 955 individuals (47.4%) were from the physical examination group. Over an 11-year period, the logarithmically transformed TG (lnTG) in the general population slightly increased from 1.35 mmol/L to 1.36 mmol/L (Sen slope=0.007 mmol·L -1·year -1; S=27, P=0.043). Although there were fluctuations in TC, LDL-C, and HDL-C, the trends were not statistically significant ( P>0.05). However, in the subset of the population undergoing regular health check-ups, TC showed a steady increase over time ( S=27, P=0.043). Within a fixed population over the same 11-year period, there were no statistically significant changes in lipid profiles ( P>0.05). Nevertheless, in the fixed subset undergoing regular health check-ups, both TC and lnTG exhibited an upward trend (TC: S=27, P=0.043; lnTG: S=31, P=0.020), while in the fixed subset seeking medical attention, TC and LDL-C demonstrated a downward trend (TC: S=-31, P=0.020; LDL-C: S=-27, P=0.043). Trends in lipid profiles varied among different genders and age groups. Specifically, both men and women aged 20-<40 years old showed an increase in TC, abnormal TC rates, and abnormal LDL-C rates ( P<0.05). Conversely, in the fixed population, women over 60 years old exhibited a decrease in TC, abnormal TC rates, and abnormal LDL-C rates ( P<0.05). Conclusion:During the period from 2014 to 2024, there were slight fluctuations in the average lipid levels of both the general and fixed populations. Notably, TC, abnormal TC rates, and abnormal LDL-C rates increased among men and women aged 20-<40 years old, while these parameters decreased among women over 60 years old in the fixed population.

Protein ubiquitin-like modification of Neddylation is an important post-translational modification mode of protein to widely regulate cell cycle, growth, development and other biological processes. Recent studies have found that MLN4924, small molecule inhibitor of Neddylation modification, has a significant anti-tumor effect, which can inhibit the tumor growth by inducing cell cycle arrest, senescence and apoptosis, and inhibiting tumor angiogenesis. This paper reviews the related mechanism research of cell programmed death induced by Neddylation modification pathway inhibitor MLN4924.

Neddylation is overactivated in lung cancer, which promotes the development of lung cancer by activating its downstream CRL ubiquitin ligase and promoting the CRL tumor-suppressor protein substrate degradation. MLN4924, a small molecule inhibitor of Neddylation, plays an anti-lung cancer role by inducing cell cycle arrest, apoptosis and senescence. Furthermore, targeting the key enzymes of Neddylation and their substrates, Cullin family proteins, can inhibit the development of lung cancer.
