The agglomeration of the rural e-commerce industry represented by Taobao villages has reshaped the existing urban and rural spatial organization and proposed a new urbanization *** study identified the spatiotemporal characteristics of Taobao villages in Quanzhou city and built panel regression models to examine the impact of these villages on urbanization level,which is measured via nighttime light(NTL).The results show that(1)while the number of Taobao villages in Quanzhou city has increased rapidly,it has also experienced sporadic growth and monocentric agglomeration,finally forming a polycentric agglomeration pattern;(2) Taobao villages display a significant near-city tendency,and the urbanization level of towns with Taobao villages is higher than that of towns without Taobao villages;(3) the panel regression model highlights that Taobao villages have a significant positive impact on urbanization *** villages near the city exhibit a greater effect;meanwhile,those that are far away from the city cannot improve their urbanization level unless they reach a considerable degree of *** e-commerce will become an important direction for the transformation of urban fringe areas,which provides a certain reference for the development of new urbanization in China.

Receptor-interacting protein(RIP)kinases are a group of threonine/serine protein kinases with a relatively conserved kinase domain but distinct non-kinase regions.A number of different domain structures,such as death and caspase activation and recruitment domain(CARD)domains,were found in different RIP family members,and these domains should be keys in determining the specific function of each RIP *** is known that RIP kinases participate in different biological processes,including those in innate immunity,but their downstream substrates are largely *** review will give an overview of the structures and functions of RIP family members,and an update of recent progress in RIP kinase research.

The objective of this study was to analyze the relationship of somatic cell count （SCC） with milk yield, fat and protein percentage, fat and protein yield using analysis of variance and correlation analysis in Chinese Holstein population. The 10 524 test-day records of 568 Chinese Holstein Cattle were obtained from 2 commercial herds in Xi＇an region of China during February 2002 to March 2009. Milk yield, fat percentage, fat and protein yield initially increased and then dropped down with parity, whereas protein percentage decreased and SCC increased. Analysis of variance showed highly significant effects of different subclasses SCC on milk yield and composition （P〈 0.01）. Compared with milk yield with SCC ≤ 200 000 cells mL-1, milk yield losses with SCC of 200 000-500 000 cells mL-1, 501000-1 000 000 cells mL-1, ≥ 1 000 000 cells mL-1 were 0.387, 0.961 and 2.351 kg, respectively. The highly significant negative correlation coefficient between somatic cell score （SCS） and milk and protein yield, milk yield and fat and protein percentage, protein percentage and fat yield were -0.084, -0.037, -0.061, -0.168, and -0.088, respectively （P〈 0.01）. The highly significant positive correlation coefficients between SCS and fat yield and fat and protein percentage, milk yield and fat and protein yield, fat percentage and protein percentage and fat yield, protein yield and protein percentage and fat yield were 0.041, 0.177, 0.105, 0.771, 0.865, 0.122, 0.568, 0.318, and 0.695, respectively （P〈 0.01）. There was no significant relationship between fat percentage and protein yield （P 〉 0.05）. The results of the present study first time provide the relevant base-line data for assessing milk production at Xi＇an region of China.

A new and simple capillary electrophoresis with electrochemiluminescence detection was developed for the separation and the quantification of a pair of diastereoisomenc alkaloids（ephedrine and pseudoephedrine）.The limits of detection（S/N = 3） were 4.5×10^-8 mol/L for ephedrine and 5.2×10^-8 mol/L for pseudoephedrine,*** RSDs of migration time and peak area were less than 1.3 and 2.5%（n = 5）,*** applicability of the propose method was illustrated in the determination of ephedrine and pseudoephedrine in human urine,ephedrine in nasal drops,and the monitoring of pharmacokinetics for pseudoephedrine.
