Fever in cancer patients is often due to the following causes: evil qi and toxity stagnancy, disorders of qi and blood, deficiencies of zang and fu organs, and the disorder of yin and yang. The treatments given to cancer patients with a fever are according to five: (a) Excessive inner heat and toxicants: remove heat and the toxicant, induce purgation. We use Cheng-Qi-Tang plus Qing-Wen-Bai-Du-Yin. (b) Tangle of damp and heat, and qi stagnancy: remove damp and heat, smooth the qi channel. We use Gan-Lu-Xiao-Du-Dan or San-Ren-Tang. (c) Obvious blood and heat stagnancy: remove heat and blood stasis. We use Xue-Fu-Zhu-Yu-Tang. (d) Deficiency of spleen qi, inner heat caused by a yin deficiency: nourish spleen qi and yin to remove the inner heat. We use Bu-Zhong-Yi-Qi-Tang or Xiao-Jian-Zhong-Tang. (e) Prominent yin deficiency and hectic fever: replenish yin and remove inner heat. We use Qing-Hao-Bie-Jia-Tang or Chai-Qian-Mei-Lian-San. The pathogenesis of fever in cancer patients is complicated. We can see both deficiency and excess in one differentiation. Therefore, we must make sure of it, then we can get the most effective treatment.

Xue Peng,Jiangtao Zhai,Zhu Juan,Wang Meixian,Zhao Qiaoling,Huang Jinshan,Tang Shunming,Shen Xingjia 한국응용곤충학회 2021 Journal of Asia-Pacific Entomology Vol.24 No.1

N6-methyladeosine (m 6 A) plays an important role in virus infection and replication. Bombyx mori nuclear polyhedrosis is caused by Bombyx mori nucleopolyhedrovirus (BmNPV) infection. Expression levels of m 6 Amodification-related genes after the infection of BmNPV were detected at first. Then, expression levels of BmNPV nucleocapsid protein gene VP39 and envelope fusion protein gene GP64 after knockdown of METTL3in vitro were quantified to identify the effect of m 6 A modification on BmNPV. BmNPV firstly infects the larval midgut in case of oral infection. Subsequently, to clarify the relationship between m 6 A modification and resistance of the silkworm to BmNPV, we detected the expression levels of m 6 A-modification-related genes invivo before and after infection of BmNPV. The results indicated that low METTL3 level hindered the proliferation of BmNPV to some extent, and silkworm strain with low METTL3 level showed stronger resistance against BmNPV. This study will accumulate new experimental data for elucidating the resistance mechanism of silkworm against BmNPV.

Throughput Maximization in Cooperation Based Symbiotic Cognitive Radio Networks

XUE, Peng,GONG, Peng,KIM, Duk Kyung The Institute of Electronics, Information and Comm 2010 IEICE TRANSACTIONS ON COMMUNICATIONS - Vol.93 No.11

<P>In the symbiotic cognitive radio (CR) networks, the CR users (CUs) may assist the primary transmission in a cooperation time, and obtain an incentive time for their own data transmission. In this letter, we study the throughput maximization problem in the symbiotic CR networks. Under the symbiosis and transmit power constraints, we aim to find the optimal cooperation time to assist the primary transmission and power allocations among the CUs. Given the cooperation time, the optimal power allocations can be solved by multi-level water-filling (MWF) with individual volume limits. A theoretical analysis is presented on the cooperation time and a modified bisection algorithm with low complexity is proposed to find the sub-optimal cooperation time. Simulation results show that the spectrum usage efficiency can be significantly improved as the number of CUs increases.</P>

Improved antimicrobial effect of ginseng extract by heat transformation

Peng Xue,Yang Yao,Xiu-Shi Yang,Jia Feng,Gui-xing Ren 고려인삼학회 2017 Journal of Ginseng Research Vol.41 No.2

Background: The incidence of halitosis has a prevalence of 22e50% throughout the world and is generally caused by anaerobic oral microorganisms, such as Fusobacterium nucleatum, Clostridium perfringens, and Porphyromonas gingivalis. Previous investigations on the structure-activity relationships of ginsenosides have led to contrasting results. Particularly, the antibacterial activity of less polar ginsenosides against halitosis-related bacteria has not been reported. Methods: Crude saponins extracted from the Panax quinquefolius leaf-stem (AGS) were treated at 130C for 3 h to obtain heat-transformed saponins (HTS). Five ginsenoside-enriched fractions (HTS-1, HTS-2, HTS-3, HTS-4, and HTS-5) and less polar ginsenosides were separated by HP-20 resin absorption and HPLC, and the antimicrobial activity and mechanism were investigated. Results: HPLC with diode-array detection analysis revealed that heat treatment induced an extensive conversion of polar ginsenosides (-Rg1/Re, -Rc, -Rb2, and -Rd) to less polar compounds (-Rg2, -Rg3, -Rg6, -F4, -Rg5, and -Rk1). The antimicrobial assays showed that HTS, HTS-3, and HTS-4 were effective at inhibiting the growth of F. nucleatum, C. perfringens, and P. gingivalis. Ginsenosides-Rg5 showed the best antimicrobial activity against the three bacteria, with the lowest values of minimum inhibitory concentration and minimum bactericidal concentration. One major reason for this result is that less polar ginsenosides can more easily damage membrane integrity. Conclusion: The results indicated that the less polar ginsenoside-enriched fraction from heat transformation can be used as an antibacterial agent to control halitosis.

A Study on Corporate Governance of Chinese Privately Owned Enterprises Listed in Hong Kong -From the Perspective of the Government-Business Relations

( Xue Peng ) 고려대학교 법학연구원 2015 The Asian Business Lawyer Vol.15 No.-

Chinese privately owned enterprises (POEs) or “Mainland Private Enterprises (MPEs)” as categorized by the Stock Exchange of Hong Kong have become a significant component of Hong Kong’s capital market, while the research on their corporate governance issues are far from adequate. Meanwhile, among the corporate governance failures occurred to these companies, it is observed that government officials or governmental authorities in the Mainland are involved in many cases. In this connection, this article tries to analyze corporate governance of Chinese POEs listed in Hong Kong from the perspective of their relationship with one of their vital stakeholders . Mainland local governments. In the context of government-business relations in China, it is found that, as a significant stakeholder of Chinese POEs, local governments in China have not only played a central role in the evolvement of China’s private sector, but also have had a major impact on corporate governance practices of Chinese POEs listed on overseas capital market. Indeed, the government-business relation is a double-edged sword to these companies. The lawful participation of controllers in the Mainland local political system may benefit the company in the long run, while too closely enmeshed ties between businesses and governments may pose huge risks to overseas listed POEs. Therefore, in today’s China where the government still plays a key role in the economy and is the final decision maker in many strategically important industries, establishing and maintaining a healthy and sustainable government-business relation is not only indispensable for a Chinese private enterprise to survive in Chinese business environments, but also beneficial to its performance on overseas capital markets.

The Political Economy of Free Trade Agreements: an Empirical Investigation

( Xue Peng Liu ) 세종대학교 경제통합연구소 (구 세종대학교 국제경제연구소) 2008 Journal of Economic Integration Vol.23 No.2

This paper studies how income inequality affects the probability of signing free trade agreements (FTAs) in a political economy framework. The median voter approach to FTA formation within a Heckscher-Ohlin framework predicts that an increase in inequality lowers the desirability of an FTA if the partner country is relatively labor abundant, ceteris paribus, and raises the desirability of such an agreement if the partner country is relatively capital abundant. The lobbying model based on the argument of the free rider problem, however, offers the opposite predictions. This paper proposes a duration analysis for bilateral FTA panel data and finds strong support for the predictions from the median voter model.

Improved Multi-Cell Joint Channel Estimation for the TD-SCDMA Downlink

XUE, Peng,CAO, Ning,KANG, Dong Kwan,KIM, Duk Kyung The Institute of Electronics, Information and Comm 2009 IEICE TRANSACTIONS ON COMMUNICATIONS - Vol.92 No.4

<P>In this paper, a multi-cell joint channel estimation (JCE) method is proposed for the TD-SCDMA downlink. In the proposed multi-cell JCE approach, the received midambles from adjacent cells are jointly processed, rather than being treated as interference as in single cell channel estimation. By jointly processing all the received midambles, the user can simultaneously estimate the channel impulse responses (CIRs) for both its home cell and adjacent cells. If the received signal from adjacent cells has a delay, multi-cell JCE is still operable with slight adjustment in the midamble matrix, and the performance loss is also minor. The performance of multi-cell JCE is analyzed and evaluated by simulations. The results demonstrate that the proposed multi-cell JCE method can significantly improve the channel estimation accuracy. When the signal from each cell has similar power level, the mean square error (MSE) of the estimated CIRs for all cells is lower than 0.01. With more accurate CIRs from multi-cell JCE, multi-cell JD also yields better performance compared with the single cell channel estimation methods.</P>

Optimum Power Allocation in a Nonorthogonal Amplify-and-Forward Relay-Assisted Network

Peng Gong,Peng Xue,Daeyoung Park,Duk Kyung Kim IEEE 2011 IEEE TRANSACTIONS ON VEHICULAR TECHNOLOGY Vol.60 No.3

<P>In this paper, we address the problems of power allocation at relays to maximize the transmission rate in a nonorthogonal amplify-and-forward (AF) relay-assisted network, in which multiple relays simultaneously transmit the amplified signals in the same time and frequency. We first formulate a power allocation problem that aims to maximize the minimum of transmission rates in a multicast under a sum power constraint. Then, we prove that the optimal solution can be alternatively obtained by solving its inverse problem, which minimizes the sum power consumption at relays while achieving the target signal-to-noise ratio (SNR) with the same constraint. The inverse problem can be solved by using linear programming, and the inverse problem's complexity can be further reduced by a proposed suboptimal power allocation algorithm. As in the special case of multicast, the optimal solution is derived in unicast, and two suboptimal algorithms are proposed to reduce the feedback overhead and complexity, in which multirelay diversity is also investigated.</P>
