AIM To investigate the pathophysiologic basis of syndrome of Liver Qi stagnation and parameters for clinical differentiation. METHODS Plasma L ENK, AVP, ANP and serum gastrin were determined by RIA in 84 patients with neurasthenia, mastodynia, chronic gastritis, and chronic cholecystitis presenting the same syndrome of Liver Qi stagnation in traditional Chinese medicine (TCM). Healthy subjects served as controls in comparison with patients having the same syndrome but with different diseases. RESULTS Among the patients with Liver Qi stagnation, the plasma L ENK, ANP and gastrin levels were 38 83ng/L ± 6 32ng/L , 104 11ng/L ± 29 01ng/L and 32 20ng/L ± 6 68ng/L , being significantly lower than those in the healthy controls ( t =3 34, 6 17, 4 48; P 0 05. CONCLUSION The syndrome of Liver Qi stagnation is closely related to the emotional modulatory abnormality of the brain, with decrease of plasma L ENK, ANP and gastrin, and increase of plasma AVP as the important pathophysiologic basis.

A memory compress algorithm for 12\|bit Arbitrary Waveform Generator (AWG) is presented and optimized. It can compress waveform memory for a sinusoid to 16×13bits with a Spurious Free Dynamic Range (SFDR) 90.7dBc (1/1890 of uncompressed memory at the same SFDR) and to 8×12bits with a SFDR 79dBc. Its hardware cost is six adders and two multipliers. Exploiting this memory compress technique makes it possible to build a high performance AWG on a chip.

根据电荷守恒原理对MCS(merged-capacitor switching)技术的原理进行了详细地阐述与分析。分析结果表明,采用MCS技术的MDAC除了需要信号地外,与传统MDAC在功能上是一致的,而且,在速度与功耗保持不变的情况下,可获得更高的电容匹配精度,从而降低了MDAC对电容失配的敏感度。此外,结合MCS技术和CFCS(commutated feedback capacitorswitching)技术,提出了一种低DNL1.5位MDAC。数学分析表明,与典型的1.5位MDAC相比,所提出的1.5位MDAC中的电容失配对流水线ADC的DNL的影响明显减小且只需增加一个多路选择器,电路实现仍然简单,速度与功耗也维持不变。

Realizing the valley Hall effect by breaking the spatial inversion symmetry of photonic systems has become a cutting-edge field of micro-nano-optics, since the valley degree of freedom was introduced into photonic system. Various novel devices based on the domain walls of the valley photonic crystals have also been demonstrated. In this article,we investigate the variation of edge states by the modulation of refractive index within the domain walls, and the geometric difference between the dielectric columns of the sublattices. Straight photonic crystal waveguides with three types of domain walls (bearded, zigzag, armchair) are constructed. Simulation results show that the creation of a double-edge state in the band diagram results in two windows of stable transmission in tunable bands. Our findings might have significant implications in the field of novel optical devices.
