Ischemic cerebral stroke is one of the diseases posing great threat to human health.It is of great value to have a correct evaluation and interpretation of cerebral angiography in interventional treatment of ischemic stroke together with efficacy.The authors reviewed the direct signs and collateral circulation of ischemic cerebral stroke and the evaluation of cerebral angiography in recent literature.

Aim To study the adaptive protection of H_2O_2 preconditioning against dopamine-induced damage in PC12 cells.Methods The apoptosis of PC12 cells was observed by electron microscope, PI stain flow cytometry (FCM) and Hoechst stain. The mitochondrial energy redox state was measured by MTT assay. The mitochondrial membrane potential(△?m) was investigated by the fluorescent probe of rhodamine 123.Results PC12 cells exposed to 50 ?mol?L -1 DA showed chromatin condensation and nucleus fragmentation observed by electron microscope. Exposure to DA (50 ?mol?L -1) for 24 h, the apoptosis of PC12 cells preconditioned by 10 ?mol?L -1 H_2O_2 for 90 min as measured by Hoechst stain was significantly decreased,compared with no-preconditioned cells. Exposure to 50,100,and 200 ?mol?L -1 H_2O_2 for 24 h, the proportion of apoptosis of PC12 cells was decreased from (20.9?1.8)%, (40.5?6.4)% and (88.1?3.9)% to (4.9?2.9)%, (12.0?1.4)%, (61.5?3.4)% after H_2O_2 preconditioning, respectively. By exposuring PC12 cells to 20,40,and 80 ?mol?L -1 DA for 24 h, the rates of MTT metabolism were reduced and the effect was prevented by H_2O_2 preconditioning. After 50 ?mol?L -1 DA exposure for 24 h,the mean fluorescence intensity of rhodamine 123 in no-preconditioned PC12 cells was decreased from (46.87?0.33) to (4.39?2.93),and that of preconditioned PC12 cells was decreased from (46.87?0.33) to (10.50?0.28). Conclusion H_2O_2 preconditioning possesses adaptive protection against dopamine-induced damage in PC12 cells.

Objective To investigate the effect of diet on the expression of protein tyrosine phosphatase (PTP) 1B in liver of insulin resistant rats induced by high fat diet. Methods 30 male Wistar rats were randomly divided into the control group (n=10) which was given basic diet, and the model group (n=20) which was given high fat diet. After 4 weeks, the model group was randomly divided into 2 subgroups:insulin resistant group which continued to receive high fat diet, and diet-treated group which accepted diet intervention for 6 weeks. The protein expression level of PTP1B in the liver of rats were determined with western blotting at the end of 10th week. Results The protein content of PTP1B in the liver of insulin resistant rats significantly increased by 98.3% compared with the control group (t=9.335,P

Traditional Chinese medicine has multi-component, multi-target, and multi-path action characteristics and complexity, which makes the task of modernizing traditional Chinese medicine arduous, and many medical researchers have made unremitting efforts to this end. The development of systems biology and omics has ushered in an opportunity for the integration of traditional Chinese medicine and modern science. In particular, the characteristics integrity, dynamics, personalization, and interaction with the environment of epigenetics and metabolomics are consistent with function concept of traditional Chinese medicine. The application of popular DNA methylation, histone modifications, miRNA regulation of epigenetic research, and the application of metabolomics in the substance basis, quality control, pharmacodynamic action mechanism in traditional Chinese medicine research are reviewed in this paper. This paper also puts forward the idea that combining the two and innovative application can clarify the scientific connotation of the whole action mechanism of traditional Chinese medicine and the mechanism of multi-component, multi-channel, and multi-target synergistic action at the micro level, and explore a new research model for the scientific connotation of the core thought of traditional Chinese medicine.

Objective To explore the spatial distribution and spatial clustering of brucellosis in Zibo,2013-2015.Methods Spatial autocorrelation analysis was used to analyze the surveillance data of brucellosis at town level.Township as a spatial analysis unit,spatial distribution of brucellosis in small scale in Zibo City was analyzed.Results The global Moran's I indexes of brucellosis were not significantly different in 2013-2015.According to local Moran's Ⅰ statistic,the high-high regions were Xindian Street and Jiangjunlu Street in 2013.The high-high regions were Tangfang Town,Jinshan Town,Luocun Town,Zhaili Town,Xihe Town and Longquan Town in 2014.The high-high region was Wangcun Town in 2015.Condusions Our study has showed that the spatial distribution of brucellosis is local clustered in Zibo.The detection of hotspots could provide guidance for formulating regional prevention and control strategies.
