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.

A high-performance liquid chromatographic (HPLC) method was established to analyze 36 Chaihu (Radix Bupleuri) samples collected from three species (Bupleurum chinense DC., B. scorzonerifolium Willd. and B. smithii Wolff.). Addition of trifluoroacetic acid into the mobile phase resulted in fingerprint chromatograms with stable baselines. There were thirty-two characteristic peaks in the standard fingerprint of B. chinense DC. Different recognition pattern methods, including similarity analysis (SA), hierarchical cluster analysis (HCA), principal component analysis (PCA) and partial least squares-discrimination analysis (PLS-DA) were utilized to analyze the 36 samples based on the contents of chemical constituents. Consistent results from SA, HCA and PCA analysis illustrated the rationalisation for why B. smithii Wolff. was not quoted in the Chinese Pharmacopoeia and classified samples were in agreement with their species. PLS-DA loading plots showed the chemical markers which had the most influences on the separation among different species. However, SA, HCA and PCA could not differentiate between wild and cultivated B. chinense DC. as well as between samples from different provinces. HPLC fingerprint in combination with chemometric techniques provided a very flexible and reliable method for homogeneity evaluation and quality assessment of traditional Chinese medicine.

Jie Xiao,Ge Guo,Yali Li,Byoung Ryong Jeong 한국원예학회 2021 한국원예학회 학술발표요지 Vol.2021 No.5
Hydrangea macrophylla is a popular perennial ornamental shrub grown commercially as potted plants, landscape plants, and cut flowers. The aim of this work was to investigate effect of iron (Fe) source and medium pH on growth and development of H. macrophylla in vitro. The Fe sources used, including non-chelated iron sulfate (FeSO4) and iron ethylenediaminetetraacetic acid (Fe-EDTA), were supplemented to the multipurpose medium with a final Fe concentration of 2.78 mg·L<sup>-1</sup>. The medium without any supplementation of Fe was used as the control. The pH of the agar-solidified medium was adjusted to either 4.70, 5.70, or 6.70 before autoclaving. The experiment was conducted in a culture room for 60 days at 25/18°C day and night temperatures, and a 16hour photoperiod provided at a light intensity of 50 mmol·m<sup>-2</sup>·s<sup>-1</sup> photosynthetic photon flux density (PPFD) from white light emitting diodes. Both Fe source and pH affected growth and development of the micro propagated plantlets in vitro. The leaf color was greener in the pH 4.70 treatment regardless of the Fe source. Besides, both Fe sources increased the leaf chlorophyll content. Numbers of shoots and roots in plantlets treated with FeSO4 were 2.0 and 2.7 times greater than those of the control, respectively. Fresh and dry weights of the shoot and the root were the greatest in the treatment of FeSO4 combined with pH 4.70. The tissue Fe content decreased with the increasing medium pH, and contents of potassium (K), calcium (Ca), and magnesium (Mg) in the plantlets increased in the pH 4.70 treatment regardless of the Fe source. Overall, the plantlet absorbed more Fe in the pH 4.70, and FeSO4 combined with pH 4.70 was found to be the best for growth and development of H. macrophylla plantlets in vitro.
Stability Analysis of Grid-Connected Inverters with an LCL Filter Considering Grid Impedance
Xiao-Qiang Li,Xiao-Jie Wu,Yi-Wen Geng,Qi Zhang 전력전자학회 2013 JOURNAL OF POWER ELECTRONICS Vol.13 No.5
Under high grid impedance conditions, it is difficult to guarantee the stability of grid-connected inverters with an LCL filter designed based on ideal grid conditions. In this paper, the theoretical basis for output impedance calculation is introduced. Based on the small-signal model, the d-d channel closed-loop output impedance models adopting the converter-side current control method and the grid-side current control method are derived, respectively. Specifically, this paper shows how to simplify the stability analysis which is usually complemented based on the generalized Nyquist stability criterion (GNC). The stability of each current-controlled grid-connected system is analyzed via the proposed simplified method. Moreover, the influence of the LCL parameters on the stability margin of grid-connected inverter controlled with converter-side current is studied. It is shown that the stability of grid-connected systems is fully determined by the d-d channel output admittance of the grid-connected inverter and the inductive component of the grid impedance. Experimental results validate the proposed theoretical stability analysis.

The optimization of a transmission type bremsstrahlung conversion target was carried out with MonteCarlo code FLUKA for intense pulsed electron beams with electron energy of several hundred keV formaximum photon fluence. The photon emission intensity from electrons with energy ranging from300 keV to 1 MeV on tungsten, tantalum and molybdenum targets was calculated with varied targetthicknesses. The research revealed that higher target material element number and electron energy leadsto increased photon fluence. For a certain target material, the target thickness with maximum photonemission fluence exhibits a linear relationship with the electron energy. With certain electron energy andtarget material, the thickness of the target plays a dominant role in increasing the transmission photonintensity, with small target thickness the photon flux is largely restricted by low energy loss of electronsfor photon generation while thick targets may impose extra absorption for the generated photons. Thespatial distribution of bremsstrahlung photon density was analyzed and the optimal target thicknessesfor maximum bremsstrahlung photon fluence were derived versus electron energy on three targetmaterials for a quick determination of optimal target design

How to deal with the relationship between fairness and efficiency has been an important dispute in public policy practices, as is the case for environmental policy in Mainland China. This paper examines the fairness and efficiency principles in Chinese environmental policy from the perspective of environmental policy instruments. First, an evaluation framework for fairness and efficiency are established. Then, the authors evaluate different levels of fairness and efficiency principles inherent in various environmental policy tools based on the evaluation framework, after a brief investigation into the development of the policy instruments. The authors finally conclude that the notions in Chinese environmental policies have gradually transferred to the comprehensive efficiency principles that consist of political feasibility, economic costs, administrative operability and environmental effectiveness. The efficiency-oriented notion is beneficial to Chinese environmental protection enterprises, as it can achieve the environmental objectives with minimum political, administrative and economic costs.
