Aim To investigate the effect of fenofibrate on focal cerebral ischemia injury in rats and its mechanism.Methods The rat model of global cerebral ischemia/reperfusion injury was established by bilateral common carotid arteries occlusion combined with hemorrhagic hypotension.Fenofibrate (33, 100, 300 mg·kg~(-1)) was intragastriclly administered 30 min before the operation, MK886 (6 mg·kg~(-1)) was given intraperitoneally 30 min before administration of fenofibrate (300 mg·kg~(-1)).Morris water maze was used to evaluate the ability of spatial learning and memory function.HE staining was used to observe pathological morphological changes of hippocampal neurons. NF-κBp65 expression was detected by immunohistochemistry, SOD activities and MDA contents were analyzed by biochemistry, and IL-1β, IL-6, IL-10, TNF-α levels were detected by ELISA.Results Fenofibrate remarkably improved the spatial learning and memory function, obviously prevented the hippocampal neurons from karyopycnosis and losing induced by I/R. Fenofibrate significantly blunted the increase of MDA, NF-κBp65, TNF-α, IL-1β, IL-6, and the decrease of IL-10 and SOD activities of I/R rats.Conclusions Fenofibrate has an obviously neuroprotective effect on global cerebral ischemia/reperfusion damage by activating PPARα.The anti-inflammation and antioxidative stress of fenofibrate may be involved in the protective mechanism.

The academic orientation determines the development direction of the subject, and also puts forward the corresponding requirements for the professional teaching. The deep development of anes-thesiology, perfect preoperative evaluation, refined management of clinical anesthesia and ultimately improv-ing the prognosis of patients are the total development directions of anesthesiology. Perioperative patient home (PSH) advocates taking patients as the center, dominated by anesthesia, based on evidence-based medicine in the perioperative period, solidarity and cooperation of multiple disciplines, the integration of a variety of medical resources, and providing continuous and efficient medical services for patients. PSH is required to ensure the safety of clinical anesthesia, reduce the incidence of anesthesia mortality and serious
complications, and improve the long-term survival rate and quality of life by improving the clinical work of the department of anesthesia. Practicing PSH, the anesthetic doctors should have the academic idea of the treatment of anesthesia. The concept requires making comprehensive use of a variety of teaching methods, putting emphasis on the training of basic knowledge, and in the teaching of basic knowledge, infiltrating the overall and local thinking and using lecture method in cooperation with the case teaching. To make solid promotion of PSH concept, we should use CBL teaching, strengthening the management of clinical anesthesia, and striving to promote the clinical practice of PSH.

It is found in clinical practice that decisions made by agents on hehalf of the patients without capability of independent choice may sometimes conflict interests of the patient in question. The author summarized by categories common dilemmas faced by clinicians, and came up with the ethical principles to resolve the problems, as proven in case studies. Doctors should fully respect reasonable decisions of agents of such patients. Furthermore, to make a reasonable decision on their behalf, the agent is expected to make medical decisions in the interests of the life and health of the patient, with adequate knowledge of the disease, therapeutic measures and outcomes, and without any damage to interests of the patient they represent. Such a reasonable decision should neither violate laws of the state, nor infringe on interests of other individuals, collectives and the society at large for benefits of the patient in question. In addition, it should conform to the medical ethics of fair distribution of health resources.

As one of the most sensitive cells of endoplasmic retieulum stress (ERS), pancreatic β-cells have an a-bundance of endoplasmic reticulum. Fatty acids cause apoptosis of β-cells and might contribute to β-cell loss in type 2 diabetes mellitus via the induction of ERS. Glucose is an amplifier of the ERS response to fatty acid, leading to increased β-cell apoptosis. ERS response mediates glucolipotoxicity-induced β-cell apoptosis.
