RESUMEN

Cholesterol is an important precursor of many endogenous molecules. Disruption of cholesterol homeostasis can cause many pathological changes, leading to liver and cardiovascular diseases. CYP1A is widely involved in cholesterol metabolic network, but its exact function has not been fully elucidated. Here, we aim to explore how CYP1A regulates cholesterol homeostasis. Our data showed that CYP1A1/2 knockout (KO) rats presented cholesterol deposition in blood and liver. The serum levels of low-density lipoprotein cholesterol, high-density lipoprotein cholesterol and total cholesterol were significantly increased in KO rats. Further studies found that the lipogenesis pathway (LXRα-SREBP1-SCD1) of KO rats was activated, and the key protein of cholesterol ester hydrolysis (CES1) was inhibited. Importantly, lansoprazole can significantly alleviate rat hepatic lipid deposition in hypercholesterolemia models by inducing CYP1A. Our findings reveal the role of CYP1A as a potential regulator of cholesterol homeostasis and provide a new perspective for the treatment of hypercholesterolemia.

RESUMEN

ObjectiveThe research provided the constructive ideas for evaluation and training of deans of tertiary hospital by analyzing the leadership status quo through using the situational judgment test based on the leadership contingency theory.MethodsBased on the leadership contingency theory,we designed situational judgment test for the dean of tertiary hospital.There were 215 participants involved in the leadership evaluation. Results The coaching leadership style occupied the mainly leadership style of deans of tertiary hospital.In the management situation matched by the coaching leadership style,the leadership of the deans was significantly higher than other management situations.Conclusion The main conclusion included,firstly,the coaching leadership style was the mainly leadership style of deans of tertiary hospital.It was strongly correlated with the deans' background thatthey were mainly from clinical professionals.Secondly,the leadership of the deans was at middle level;therefore,it needed to increase the capacity building of deans through management training.
