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.

Cinnamaldehyde Derivatives Inhibit Coxsackievirus B3-Induced Viral Myocarditis

( Xiao-qiang Li ),( Xiao-xiao Liu ),( Xue-ying Wang ),( Yan-hua Xie ),( Qian Yang ),( Xin-xin Liu ),( Yuan-yuan Ding ),( Wei Cao ),( Si-wang Wang ) 한국응용약물학회 2017 Biomolecules & Therapeutics(구 응용약물학회지) Vol.25 No.3

The chemical property of cinnamaldehyde is unstable in vivo, although early experiments have shown its obvious therapeutic effects on viral myocarditis (VMC). To overcome this problem, we used cinnamaldehyde as a leading compound to synthesize derivatives. Five derivatives of cinnamaldehyde were synthesized: 4-methylcinnamaldehyde (1), 4-chlorocinnamaldehyde (2), 4-methoxycinnamaldehyde (3), α-bromo-4-methylcinnamaldehyde (4), and α-bromo-4-chlorocinnamaldehyde (5). Neonatal rat cardiomyocytes and HeLa cells infected by coxsackievirus B3 (CVB3) were used to evaluate their antiviral and cytotoxic effects. In vivo BALB/c mice were infected with CVB3 for establishing VMC models. Among the derivatives, compound 4 and 5 inhibited the CVB3 in HeLa cells with the half-maximal inhibitory concentrations values of 11.38 ± 2.22 μM and 2.12 ± 0.37 μM, respectively. The 50% toxic concentrations of compound 4 and 5-treated cells were 39-fold and 87-fold higher than in the cinnamaldehyde group. Compound 4 and 5 effectively reduced the viral titers and cardiac pathological changes in a dose-dependent manner. In addition, compound 4 and 5 significantly inhibited the secretion, mRNA and protein expressions of inflammatory cytokines TNF-α, IL-1β and IL-6 in CVB3-infected cardiomyocytes, indicating that brominated cinnamaldehyde not only improved the anti-vital activities for VMC, but also had potent anti-inflammatory effects in cardiomyocytes induced by CVB3.

XIAO-YING QI,KAN-YI PU,QU-LI FAN,DUO-FENG TANG,GUI-AN WEN,FREDDY Y. C. BOEY,LIAN-HUI WANG,WEI HUANG,HUA ZHANG 성균관대학교(자연과학캠퍼스) 성균나노과학기술원 2008 NANO Vol.3 No.2

A series of cadmium telluride (CdTe) nanocrystals were synthesized by a modified organometallic synthesis method at various reaction temperatures ranging from 130 to 250°C. In this method, octadecylamine (ODA) was introduced as an additional coordinating component to the mixture of trioctylphosphine oxide (TOPO) and trioctylphosphine (TOP). CdO was used as a precursor. The prepared CdTe nanocrystals were studied by the absorption and emission spectra as well as the powder X-ray diffraction (XRD) patterns. The result shows that besides the traditional continuous-growth mode observed frequently at relatively high reaction temperature, a discontinuous-growth mode was confirmed at the initial growth stage of CdTe nanocrystals, arising from the change of the absorption spectra of CdTe nanocrystals with the reaction time at relatively low reaction temperature. The structures of CdTe nanocrystals, e.g., the cubic zinc blende structure at 160°C and the hexagonalwurtzite structure at 250°C, were characterized by XRD.

In order to solve the environmental pollution and the depletion of petroleum energy, construction machine with high efficiency needs to be urgently developed. In this paper we propose a new energy regenerative swing system with a hydraulic accumulator, variable hydraulic motor and proportional flow control valve for realizing highly energy efficient construction machine. Furthermore, we proposed a novel control algorithm for the reduction of vibration of upper frame of excavator as well as high energy regeneration and reuse. A test bench was fabricated, and experiments have been conducted. From the experimental results, it was verified that the mean energy regeneration efficiency and energy saving efficiency were 33.4 and 9.2% and the vibration of upper plate of excavator can be assumed to be reduced by experimental results.

<P><B>Abstract</B></P> <P>Cobalt sulfides have attracted tremendous attention as promising anodes for lithium-and sodium-ion batteries. However, the delivery of a high capacity with good cycle life conferred by carbon-free cobalt sulfides is a still challenge. In this work, carbon-free CoS<SUB>x</SUB> hollow nanospheres have been prepared and investigated as an advanced anode material for both lithium- and sodium-ion batteries. The resultant material features a unique nano-architecture with hollow core and porous shell. Based on time-dependent experiments, an Ostwald ripening process is proposed to describe the formation of the hierarchical hollow structure. By virtue of its appealing structure and conversion electrochemical reaction mechanism, remarkable electrochemical performances (e.g., high Li/Na-storage capacity, excellent cycling stability, and good rate capability) are achieved when this material is utilized as the anode materials in rechargeable batteries. For instance, a high Li/Na-storage capacity (1012.1mAhg<SUP>−1</SUP> and 572.0mAhg<SUP>−1</SUP>) can be delivered after 100 cycles at 500mAg<SUP>−1</SUP>, corresponding to satisfied capacity retentions, suggesting the great promise of this material for application in rechargeable batteries.</P> <P><B>Highlights</B></P> <P> <UL> <LI> A uniform carbon-free CoS<SUB>x</SUB> hollow structure has been prepared through an Ostwald ripening process. </LI> <LI> Remarkable cycling stability rate capability have been achieved using the designed CoS<SUB>x</SUB> anodes. </LI> <LI> The designed anode displays competitive electrochemical performance compared to carbon-contained counterparts. </LI> </UL> </P> <P><B>Graphical abstract</B></P> <P>[DISPLAY OMISSION]</P>

Regeneration of the potential energy is an effective solution to save energy. However, the conventional hybrid excavator can’t regenerate the potential energy. This paper proposes a new structure of hydraulic excavator as well as a control strategy. The focus of the paper is using hydraulic transformer to regenerate energy. The simulation is carried out by the AMESim software. From the simulation results, this new system has a high efficiency for energy saving.

Micro-Intertexture Carbon-Free Iron Sulfides as Advanced High Tap Density Anodes for Rechargeable Batteries

Xiao, Ying,Hwang, Jang-Yeon,Sun, Yang-Kook American Chemical Society 2017 ACS APPLIED MATERIALS & INTERFACES Vol.9 No.45

<P>Numerous materials have been considered as promising electrode materials for rechargeable batteries; however, developing efficient materials to achieving good cycling performance and high volumetric energy capacity simultaneously remains a great challenge. Considering the appealing properties of iron sulfides, which include low cost, high theoretical capacity, and favorable electrochemical conversion mechanism, in this work, we demonstrate the feasibility of carbon-free microscale Fe1-xS as high-efficiency anode materials for rechargeable batteries by designing hierarchical intertexture architecture. The as-prepared intertexture Fe1-xS microspheres constructed from nanoscale units take advantage of both the long cycle life of nanoscale units and the high tap density (1.13 g cm(-3)) of the micro-intertexture Fe1-xS. As a result, high capacities of 1089.2 mA h g(-1) (1230.8 mA h cm(-3)) and 624.7 mA h g(-1) (705.9 mA h cm(-3)) were obtained after 100 cycles at 1 A g(-1) in Li-ion and Na-ion batteries, respectively, demonstrating one of the best performances for iron sulfide-based electrodes. Even after deep cycling at 20 A g(-1), satisfactory capacities could be retained. Related results promote the practical application of metal sulfides as high-capacity electrodes with high rate capability for next-generation rechargeable batteries.</P>
