The expression absence of LRRC4 was ascribed to the loss of homozygosity of 7q32-ter in U251 cell lines. Conclusion The expression of LRRC4 gene is absent in glioblastoma cell lines, and it offers the important experiment proof for LRRC4 to act as a new candidate of brain tumor suppressor gene from glioma.

It is revealed that in the condensates, the different configurations of order parameters lead to different topological structures-velocity field vortex lines, Mermin-Ho vortex lines and monopoles, and these three topological structures can all be characterized by the Hopf indices and Brouwer degrees of φ-mapping, and their locations and motions also be rigorously determined by φ-mapping theory.

文中指出，在凝聚体中，序参量的不同位形导致了不同的拓扑结构—速度场涡旋线、Mermin-Ho涡旋线和单极，而这三种结构都可由Φ-映射Hopf指标和Brouwer度所表征，并且它们的位置和运动亦可由Φ-映射理论严格确定。

It is considered that influenced by the strike-slip movement of Tanlu Faults and "episodic" chasmic evolution, buried hill draping structures with different sequences are created from the north to south in Kandong-Zhuanghai buried hill draping structure.

认为受郯庐断裂带走滑运动和渤海湾盆地第三纪&幕式&裂陷演化的影响，垦东－桩海潜山披覆构造带自北向南形成不同位序的潜山披覆构造。

This paper analyses the characteristics of urban system in Anhui Province. It is found that this region exhibits a city-size distribution following the rank-size rule. The urban primacy index is low, the scale effect is inevident, the urban scale is small in whole, the development of metropolis and big cites is not enough, medium-sized cities is prominent and the spatial distribution of cities is not equal.

运用统计数据，在深入分析的基础上，发现安徽省现状城市体系的等级规模结构呈位序－规模分布；城市首位度偏低，规模效应不明显；城市规模总体偏小，特大城市和大城市发育不足，中等城市突出；城市规模空间分布不均衡，区域分异明显。

Methods: According to the mechanism of cough reflex, the c-fibres's role in the respiratory system, and the principle of isosterism. Here, a peripheral antitussive LD was regarded as a lead compound. Amino functional groups, as substituents at the 1-hydroxy group of the racemate of LD, were introduced into the structure of the molecule. These novel compounds were confirmed by 1H-NMR, MS spectrum. Their antitussive activities were studied on mice in sequential method. The EDT50, the stimulating time that caused cough by NH3 on half of mice, were measured. Then could caculated the ratio R between the EDT50 of the treated groups and control group.
