Gwae(卦氣) theory was one of the main theoretical foundation of yiology in the Han(漢)-dynasty. It was based on the concept that the trigram or hexagram of the book of change corresponds to the seasonal point such as 24 solar terms in one year, so there was so much influence from astronomy and divination system of that time in the development of theoretical principle of Gwae(卦氣) theory. Since Han(漢) Dynasty, the theoretical method such as Gwae(卦氣) theory that correlates the astronomy and divination system with the book of change, had become one of the main academic thoughts throughout the entire history in China, and it was also like that in medicine. Nevertheless there still exists the skeptical sights that Gwae(卦氣) theory was not a part of orthodox yiology, that had been developed by Confucian scholar and had also been recognized as the right path to the study of the book of change. Nowadays because of the new opportunity such as the excavation of the ancient silk script, this kind of controversy has moved on its another step. With regard to this problem, this article will treat the current thoughts about the Gwae(卦氣) theory and think about the substantial basis of each point of view.

As a study on a traditional garden with historical value, the objective of this study is to comprehensively understand the internal meanings of the garden in a designer's personal perspective. Tasanchodangwon was designed Chung Yakyong who is a scholar of Practical Learning in late Chosun Dynasty. Considering the features of him and basic approach of this study, the internal eanings of the Tasanchodangwon was approached with the focus on the view of nature of him, and through general review of physical components of the garden. Additionally the meanings of the garden were also reviewed in his personal situation. The result of the study may be summarized as followings. First, according to the view of nature of Chung Yakyong, his intention to enrich life practically by building separate structures for education for his residence, creating lake by having water supply, and creating vegetable garden relates with the view of nature in Primary confucianistic perspective. In addition, the place served as a ground to support Chung Yakyong's attitude to become a man of virtue, Second, his preference to enjoyu tea culture allowed an opportunity for him to accept circumstance positively and discover the self. Components related to farming reflects his Practical Learning. The man-made rock mountain in the pond is a specific technique for Yi-Jing. And third, literatures authored by Chung Yakyong show that internal meaning of Tasanchodangwon is to pursue an utopia. This is closely related to solving his conflicts felt in reality. In short, Tasanchodangwon is a form reflecting the spiritual world of Chung Yakyong, and through interaction with his life, served as a ground to culture his mind.

The purpose of this research is to control proper processing condition of RGB photo resistant in the ink-jet process increasing processing ability by adding additives. The viscosities of modified RGB photo resistant were $10{\sim}14cps$ and the additives could decreased agglomeration and flowing trace of photo resistant effectively. Another way, the adhesion between photo resistant and glass substrate was improved by modifying photo resistant and substrate. The surface tensions of modified photo resistant were same as that of original RGB photo resistant. The additives appeared a better compatibility with photo resistant, and the micelle of photo resistant did not be broken during modified process.

Armillifer agkistrodontis (Ichthyostraca: Pantastomida) is a parasitic pathogen, only reported in China, which can cause a zoonotic disease, pentastomiasis. A complete mitochondrial (mt) genome was 16,521 bp comprising 13 protein-coding genes (PCGs), 22 tRNA genes, 2 rRNA genes, and 1 non-coding region (NCR). A phylogenetic tree drawn with the concatenated amino acid sequences of the 6 conserved PCGs (atp6, cox1-3, and nad2) showed that A. agkistrodontis and Armillifer armillatus constituted a clade Pentastomida which was a sister group of the Branchiura. The complete mt genome sequence of A. agkistrodontis provides important genetic markers for both phylogenetic and epidemiological studies of pentastomids.

To gain a better understanding of the methylation imprinting changes associated with heat stress in early development, we used bisulfite sequencing and bisulfite restriction analysis to examine the DNA methylation status of imprinted genes in early embryos (blastocysts). The paternal imprinted genes, H19 and Igf-2r, had lower methylation levels in heat-stressed embryos than in control embryos, whereas the maternal imprinted genes, Peg3 and Peg1, had similar methylation pattern in heat-stressed embryos and in control embryos. Our results indicate that heat stress may induce aberrant methylation imprinting, which results in developmental failure of mouse embryos, and that the effects of heat shock on methylation imprinting may be gene-specific.

This paper present a current predicting control method for PMSM (permanent magnet synchronous motor) to improve the tracking performance of stator current, which regards the current vector as the control target. Solving the model state equation in the static frame (α-β frame), the dynamic change of current vector will be gained as three independent terms. These change terms, which contain the prediction of current vector, are discretized and simplified by Taylor series expansion and used to get the voltage vector as the predictive control quantity. SVPWM will transform the control voltage to the switching signal of inverter, which is newly deduced for the current vector. Simulation and experiment results are given to testy and verify the performance of this method.

Aim: The significance of the mucinous adenocarcinoma in TNM staging and prognosis for colorectal tumor patients is still controversial. The aim was to provide a meta-analysis for TNM staging and prognostic features of colorectal tumors. Methods: 30 individual case-control studies were finally included into this meta-analysis, involving a total of 444,489 cancer cases and 45,050 mucinous adenocarcinomas, of relations with TNM staging and prognostic features. Results: Compared to non-mucinous adenocarcinoma patients, the TNM IV stage accounted for a larger percentage of mucinous adenocarcinomas (OR=1.48, 95%CI 1.28-1.71, POR<0.001) and the prognosis was significantly poor (HR=1.06, 95%CI 1.04-1.08, P<0.001). After heterogeneity testing, the results was similar to the holistic approach outcome (HR=1.48, 95%CI 1.35-1.62, P<0.001). Conclusion: Compared to patients with non-mucinous adenocarcinomas, mucinous adenocarcinoma patients with later TNM staging make up a big percentage, and mucinous adenocarcinoma is an independent risk factor for poor prognosis.

Lung cancer is the leading cause of cancer-related death worldwide. Here we investigated the antitumor effect and mechanism of Zhejiang (Huzhou and Jiande) saffron against lung cancer cell lines, A549 and H446. Using high performance liquid chromatography (HPLC), the contents of crocin I and II were determined. In vitro, MTT assay and annexin-V FITC/PI staining showed cell proliferation activity and apoptosis to be changed in a dose- and time-dependent manner. The inhibition effect of Jiande saffron was the strongest. In vivo, when mice were orally administered saffron extracts at dose of 100mg/kg/d for 28 days, xenograft tumor size was reduced, and ELISA and Western blotting analysis of caspase-3, -8 and -9 exhibited stronger expression and activity than in the control. In summary, saffron from Zhejiang has significant antitumor effects in vitro and in vivo through caspase-8-caspase-9-caspase-3 mediated cell apoptosis. It thus appears to have more potential as a therapeutic agent.

TDP-43 is a ubiquitously expressed DNA/RNA binding protein that has recently attracted attention for its involvement in neurodegenerative diseases. While TDP-43 has been found to participate in various important cellular activities including stress and apoptosis, little is known about its role in cancer cells. Here we report that staurosporine (STS) induced apoptosis in U87 glioma cells is associated with rapid downregulation of TDP-43 at both mRNA and protein levels. The latter is dependent on activation of caspase 3. More importantly, we have shown that knockdown of TDP-43 by specific siRNA dramatically enhanced cytotoxicity of STS. These results suggest that normal level of TDP-43 may be protective for cancer cells under apoptotic insult.
