Background: The association and its population heterogeneities between low-density lipoprotein cholesterol (LDL-C) and all-cause and cardiovascular mortality remain unknown. We aimed to examine the dose-dependent associations of LDL-C levels with specific types of cardiovascular disease (CVD) mortality and heterogeneities in the associations among different population ***: A total of 2,968,462 participants aged 35-75 years from China Health Evaluation And risk Reduction through nationwide Teamwork (ChinaHEART) (2014-2019) were included. Cox proportional hazard models and Fine-Gray subdistribution hazard models were used to estimate associations between LDL-C categories (<70.0, 70.0-99.9, 100.0-129.9 [reference group], 130.0-159.9, 160.0-189.9, and ≥190.0 mg/dL) and all-cause and cause-specific ***: During a median follow-up of 3.7 years, 57,391 and 23,241 deaths from all-cause and overall CVD were documented. We observed J-shaped associations between LDL-C and death from all-cause, overall CVD, coronary heart disease (CHD), and ischemic stroke, and an L-shaped association between LDL-C and hemorrhagic stroke (HS) mortality (P for non-linearity <0.001). Compared with the reference group (100.0-129.9 mg/dL), very low LDL-C levels (<70.0 mg/dL) were significantly associated with increased risk of overall CVD (hazard ratio [HR]: 1.10, 95% confidence interval [CI]: 1.06-1.14) and HS mortality (HR: 1.37, 95% CI: 1.29-1.45). Very high LDL-C levels (≥190.0 mg/dL) were associated with increased risk of overall CVD (HR: 1.51, 95% CI: 1.40-1.62) and CHD mortality (HR: 2.08, 95% CI: 1.92-2.24). The stronger associations of very low LDL-C with risk of CVD mortality were observed in individuals with older age, low or normal body mass index, low or moderate 10-year atherosclerotic CVD risk, and those without diagnosed CVD or taking statins. Stronger associations between very high LDL-C levels and all-cause and CVD mortality were observed in younger peop

1897年4月,美籍法裔商人莫里斯·查维特在香港地区的放映被认为是电影最早到达中国的标志。本文通过新发现的航船信息和军事档案,确定了查维特的身份,并考证出其在华放映的33部影片的信息,内容涉及西人跳舞、洋枪马队、火车疾驰、山水雪景和皇室游行等情节,还有一些颇具感观刺激的影片。查维特的放映重视劳动分工合作,以及对中外观众进行区别放映。确认查维特身份和放映影片不仅是电影初到中国研究的深入,更能为深入理解早期电影的观影经验和观影模式奠定坚实基础。

α7烟碱型乙酰胆碱受体(α7nAChR)在中枢神经系统和免疫系统中广泛表达,发挥神经-免疫调节作用。一方面,α7nAChR参与神经递质的传递、兴奋性信号的传导和突触可塑性的维持,对于保持神经认知功能的正常与稳定具有重要意义;另一方面,α7nAChR作为胆碱能抗炎通路的重要组成部分,参与调节中枢系统炎症反应、氧化应激、细胞凋亡和自噬等生理、病理过程,发挥免疫调节和神经保护作用,是改善围手术期神经认知功能的潜在靶点。本文对α7nAChR的生物学特征及其对围手术期神经认知功能的影响进行综述,以期为临床改善手术患者的围手术期神经认知功能提供新的思路和方法。
