Based on the time-distance distributions of posterior earthquakes relative to prior ones in the regions of North China, Northwest China, Qinghai-Xizang (Tibet) plateau and Southwest China, the optimized and 90%-confidence margin curves are estimated using optimization and statistical analysis methods. This indicates that the concept and method of ETSD with 3-dimension (time-distance-magnitudes) instead of those of “recurrence interval" with 1-dimension (time) or 2-dimension (time-magnitude) provides a new approach to understanding the fluctuation of seismic activities, estimating the effective earthquake-preparation time of potential hypocenters, and therefore improving the medium- and long-term prediction of strong earthquakes.展开更多

The term “pleiotropy” means the ability of the BACs and medicines to implement more than one mechanism of action resulting in the specific biological (pharmacological) effect. The interaction of these mechanisms forms a distinct pattern of biological response (pleiotropic pattern), which reflects the change in his character with the increased dose (concentration)-dependent efficacy of BACs and medicines. The article consists of description of different pleiotropic patterns established in experiments on the model of reactive oxygen species (ROS) generation by macrophages dependent on activity of specialized enzyme called Nox2-NAD(P)H oxidase (Nox2, EC 1.6.3.1). Moreover, it consists of explanation of pharmacodynamic nature of pleiotropic patterns by means of application Chou-Talalay median effect equalization and combination index (CI) theory. The novel theory explains unsolved until now universal aspects of activity BACs and medicines, such as slope angles of “dose-effect” dependences in the conditions relevant in vivo, and it is of fundamental interest. However, it has applications in experimental pharmacology, as it allows defining the choice of the individual compounds and combinations, modulating the trust effect selectively and efficiently. This knowledge opens up new approaches to medicines discovery and evaluation, their rational dosing and combining.展开更多

Methods: According to the principle of Stratified sampling, we conducted health examination and questionnaire survey for 1500 residents over the age of 18 at observation point of chronic noninfectious diseases at 10 sub-districts (towns) of Wuhan City, Jingzhou City, Huanggang City, Shiyan City, which used descriptive statistics and logistics to regressively analyze Current situation of hypertension and its influencing factors of residents. Results: Prevalence of hypertension of rural and urban residents over 18 is 27.44% in Hubei province. There are many differences among prevalence of hypertension of male and female, distribution of BMI of rural and urban residents and prevalence of hypertension and so on, and it has statistical significance (P-value < 0.05 averagely);logistic regressive analysis result shows that different age, gender, education level, dieting habits (high salt and high oil), family per capita monthly income, BMI have statistical significance on the prevalence of hypertension in urban and rural residents of Hubei Province. Conclusions: The prevalence of hypertension in the residents of five cities and prefectures in Hubei Province is on the trend of rising in ladder form and at a much earlier age. The health education, monitoring and intervention of chronic diseases need to be widely carried out, with emphasis on the intervention of the residents’ eating habits of high salt and oil, smoking, drinking and other bad lifestyle.展开更多

This article attempts to probe into this question by citing the related cross-linguistic evidence to justify such a distinction. It concludes that some grammatical constructions or linguistic phenomena across languages cannot be well interpreted without the framework of effected-/affected-object dichotomy. Both types of objects show prototypical properties of direct objects, and they are complementary in the realization of direct-objecthood.展开更多

The Chinese Government＇s recent raft of policies to combat an economic slowdown has been dubbed ＂mini-stimulus＂ measures by some media, as it steers away from stimulus efforts involving major investments. Cutting reserve requirement ratios for certain banks, increasing railway investment, reducing taxation on small and micro-businesses, and quickening renovation of shantytowns, were some of the reforms launched earlier this year - with marked success.展开更多
