Objective To investigate the correlation between Hcy and blood lipid level and its diagnostic value in patients with cerebral infarction.Methods 218 patients with cerebral infarction were divided into the cerebral infarction group and no cercbral infarction group,based on the diagnosis results of head CT or MRI,and 60 healthy individuals were used as the control group.The levels of serum TC,TG,HDL-c,LDL-c and serum Hcy were determined in each group.The level of serum Hcy was used as a diagnostic-test and the criterion of cerebral infarction which was diagnosed by using head CT or MRI was used as a gold standard.Meanwhile,the sensibility,specificity,predictive value and likelihood ratio of Hcy were measured in patients with and without cerebral infarction.Results Levels of TC and Hcywere significantly elevated (P ＜ 0.01),but HDL-c level was significantly decreased in patients with and without cerebral infarction compared with the healthy people (P ＜ 0.05).Hcy level was shown negatively correlated with HDL-c (r =-0.144,P ＜ 0.05).The sensibility and specificity of Hcy in both two groups of patients with and without cerebral infarction were 42.20％ and 54.13％,the positive predictive value and negative predictive value of Hcy were 47.92％ and 48.36％,the positive likelihood ratio and negative likelihood ratio of Hcy were 0.92 and 1.07,respectively.Conclusion Hcy and blood lipid have definite correlation,but Hcy has low diagnostic value for cerebral infarction and may not be used as a biological marker for the cerebral infarction diagnosis.

Objective This study aims to explore the formation of the dilemma of"giving care"for disabled elderly people in nursing homes from the perspective of active health.Methods Purposive sampling was used to select caregivers and disabled elderly people from a nursing home in Chongqing as research subjects from July 2022 to December 2022.One-on-one in-depth interviews were conducted and Colaizzi's 7-step thematic analysis method was employed to collect and analyze the interview data.Results 4 themes were identified:①the dominance of the"giving"care concept,including the cultural thoughts of filial piety,passive acceptance of care characteristics and consumer psychology regarding paid services;②insufficient"participation"care ability,including lack of knowledge regarding active health and a weakening of skills to promote participation;③the hindrance to"transformation"of care models,including objective limitations in terms of human resources and delays in adapting aging environments;and ④the decline in"utilization"of internal abilities,including excessive avoidance of potential risks,a heavy workload of care and poor quality of individual care.Conclusion The formation of the dilemma of"giving care"for disabled elderly people in nursing homes is affected by multiple factors such as social background,service system,supply resources,and management mode.Transforming disabled elderly individuals from a state of"passive giving care"to"active participation in their health"is an important measure to realize the concept of positive aging and healthy aging.
