Objective To explore the relationship of lead levels in umbilical cord blood and foremilk with the neurobehavioral development of neonates with intrauterine exposure to lead at low level. Methods Lead levels in umbilical cord blood,which could be determined as indicators for intrauterine exposure to lead, were determined for 170 randomly selected neonates delivered at nanjing Maternity and Child Health Care Hospital. Neonatal behavioral neurological assessment(NBNA) total score were determined as effect index.A descriptive analysis was applied to evaluate their *** neonates were divided into two groups of high- and low-exposure based on the cutoff lead values of 10μg/dl. Results There were significant differences in scores of NBNA and initiative muscle tension with P<0.05 between the groups of high and low lead levels in umbilical cord blood,and the score of the primitive reflex showed difference with P<0.01,while no difference could be observed in the behavioral capability,passive muscle tension and general evaluation. Conclusion The lead in the foremilk could transfer to the neonates,resulting in adverse effect on the early neurobehavioral development of neonates.

The brightness temperature distribution of microwave emission in a solar active region generally shows a ring structure, with a dip at the centre. However, no dip was found in the Nobeyama Radioheliograph left handed circular polarization (LCP) image on 1992 August 18; instead, there was a peak. This is a completely LCP source with zero right-handed circular polarization (RCP). We examine this structure in terms of the joint effect of gyroresonance and bremsstrahlung mechanism with a raised electron density above the central part of the sunspot, and the commonly assumed temperature and vertical dipole magnetic field models. The raised electron density is found to be 1.4 × 1011 cm-3 at the chromosphere base.

A global adaptive strategy is proposed to make a complex dynamical network attain an inhomogeneous equilibrium point. Based on the error between the node’s state and its desired state, the coupling strength between nodes increases until the network attain an inhomogeneous equilibrium point. By constructing a Lyapunov function, a sufficient condition about the inhomogeneous equilibrium point is obtained, which is proofed by simulation, when the isolated node is a Chua’s circuit.

Forkhead Box O （FoxO） transcription factors play an important role in modulating metabolic functions. FoxOs,which are conserved among species and are regulated by the insulin signaling pathway,are usually expressed in insulin-sensitive tissues,including the liver,pancreas,skeletal muscle and gastrointestinal （GI） tract. During calorie restriction or starvation, FoxOs are predominantly localized to the cell nucleus where they activate transcription to increase hepatic gluconeogenesis,decrease insulin secretion,increase food intake and stimulate skeletal muscle degradation to supply substrates for gluconeogenesis. In insulin re-sistance or excess calorie supply,FoxOs are inactivated and lose their transcriptional activity. FoxOs also regulate the development of insulin-sensitive tissues by controlling cell differentiation,proliferation and survival. In this paper,we review the metabolic and cell cyclerelated genes controlled by FoxOs in insulin-sensitive tissues as well as their metabolic effects. Further studies into the roles of FoxOs,and the underlying mechanisms,in insulin-sensitive tissues will strengthen our understanding about tissue development and energy metabolism.

采用基于RWG基函数的传统矩量法分析目标体的电磁特性时,首先对目标体的表面剖分成三角形面片,阻抗矩阵的填充方式是按公共边循环,如果采用混合场积分方程,填充时间正比于公共边数目的平方。本文提出了一种按三角形面元循环的阻抗矩阵填充方式,该方法对场点与源点的高斯积分点数没有限制,可以实现多点高斯积分,从而大大缩短了阻抗填充时间,保证了计算结果的精度。
