Objective: To analyze the atrial fibrillation(AF) and the burden of illness(BOI) led by AF, to scientifically recognize the current situation of management and treatment for AF, to provide scientific references for designing the AF prevention and control strategy for Chinese people and effectively improve the reasonable allocation of medical resources. Methods: The disability adjusted life years(DALY)was used to evaluate the BOI of AF. The method of population attributable risk percent-age was applied to estimate the treatment cost of AF cerebral apoplexy. Results: In China, the loss of DALY brought by AF was 4 599 687 yuan, which is higher than the loss of DALY brought by hypertensive heart disease(3 348 925 yuan)and close to the loss of DALY brought by diabetes(4 769 127 yuan). The DALY of group over 30 is 7.15/1000 person. Cerebral apoplexy is the main reason for the BOI of this disease. It is estimated that the annual treatment cost of AF cerebral apoplexy is 4.9 billion yuan(about 800 million dollars), 89%of treatment cost come from patients over 60 years old with AF and cerebral apoplexy. Conclusion: AF brought heavy BOI to Chinese society. Cerebral apoplexy is the main reason for the burden of this disease. The loss of DALY led by AF cerebral apoplexy is more than the BOI of many chronic disease in India and European countries. The diagnosis and treatment cautious of AF need to be strengthened. The correct treatment results in restoring sinus thymes, so as to decrease complication like cerebral apoplexy. That would be the target of AF treatment in future China.

Flavonoid naringin is widely distributed in various types of plants and is an important component of herbal Drynaria. In previous studies, Drynaria has been demonstrated to have inhibitory effects on inflammatory responses and bone destruction and exert anabolic effects on bone, has been widely used in the clinical treatment. Naringin, was in the stage of experimental yet. The experimental results have confirmed that naringin suppressed inflammation including arthritis by lowering the expression of inflammatory cytokines, and the mechanism can be explained as reducing the expression of NF-κB. Naringin has been shown to increase osteoblast proliferation by increasing the expression of BMP-2, inhibit osteoclast activity by reducing the expression of RANKL. In animal experimental, naringin was useful for osteoporosis, and the mechanisms are in-depth studies. Research in the field of traditional Chinese medicine and orthopedics, naringin as a explicit material structure in the components of Drynaria, has been concerned about the experimental studies, it is not only prosperity the development of traditional Chinese medicine research,but also ready for clinical studies anti-inflammatory and bone effects of naringin in the future.

Objective:To evaluate the effect of sevoflurane on necroptosis in isolated hippocampal neurons and the relationship with ryanodine receptor.Methods:Primarily cultured hippocampal neurons of fetal rats of Sprague-Dawley rats were inoculated in culture wells (100 μl/well) or culture flasks (3 ml/bottle) at a density of 5×10 5 cells/ml at 7 days of culture and divided into 3 groups ( n=24 each) using a random number table method: control group (group C), sevoflurane group (group S) and ryanodine receptor antagonist group (group R). Group C received routine culture.Ryanodine receptor antagonist Dantrolene at a final concentration of 3 μmol/L was added in group R. Thirty minutes later, the cells were placed in the incubator containing 2% sevoflurane and cultured for 5 h at 37 ℃ in S and R groups.Then cells were collected, the morphology of neurons was observed with an inverted microscope, the concentrations of free calcium ion ([Ca 2+ ] i) in cytoplasm were determined by flow cytometry, the expression of ryanodine receptor and phosphorylated MLKL protein (p-MLKL) was detected by Western blot, the expression of RIP3 was measured by immunofluorescence, and necroptosis rate was calculated. Results:Compared with group C, the [Ca 2+ ] i were significantly increased, the expression of ryanodine receptor and p-MLKL was up-regulated, and the necroptosis rate was increased in S and R groups ( P<0.05). Compared with group S, the expression of ryanodine receptor and p-MLKL was significantly down-regulated, and the [Ca 2+ ] i and necroptosis rate were decreased in group R ( P<0.05). There was no obvious abnormality in the morphology of neurons in group C. The cell body of neurons were shrunk, the processes were broken, and the network between processes was sparse in group S. The cell body was round, and the morphology was close to normal in group R. Conclusion:Sevoflurane can cause necroptosis in isolated hippocampal neurons of rats, and the mechanism is related to up-regulating the expression of ryanodine receptors and leading to calcium overload.
