Peng Cao,Lan-Ying Liu,Xue-Ting Cai,Xiao-Ning Wang,Jie-Ge Huo,Zhong-Ying Zhou 셀메드 세포교정의약학회 2012 셀메드 (CellMed) Vol.2 No.2

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.

Characterization and expression of calcium-activated potassium channels (Slo) in ovary of the mud crab, Scylla paramamosain

Xue-Liang Liu,Hai-Hui Ye,Hui-Yang Huang,Jie Gong,Ya-Nan Yang 한국유전학회 2014 Genes & Genomics Vol.36 No.1

Large conductance calcium-activated potassiumchannels (Slo) play important roles in controllingneuronal excitability. At present, very little is known aboutthe function of Slo channels on ovarian development. Wecloned the SPSlo gene from the mud crab, Scylla paramamosain. This gene shows 91 and 93 % sequence identityto PISlo from the spiny lobster, Panulirus interruptus andCBSlo from the jonah crab, Cancer borealis, respectively. We isolated six variants of the SPSlo cDNA within S. paramamosain ovary tissue. Sequence analysis indicatedthat there were at least seven alternative sites in SPSlo,each with multiple alternative segments. Real-time PCRshowed that the SPSlo gene was expressed in various tissues,and highly expressed in brain and ovary. In addition,the expression of SPSlo changed throughout ovariandevelopment, highest at the early-developing stage (StageII) followed by a slow decrease in subsequent stages. Theseresults suggested that SPSlo channels may be implicated inthe ovarian development of the mud crab.

Liu, Meng-Xue,Li, Jian,Geng, Yun-Long,Wang, Yan-Chun,Li, Jie,Chen, Yu-Juan,Ali, Gholam,Tarver, Siobhan L.,Wen, Yu-Feng,Sun, Wen-Jie Asian Pacific Journal of Cancer Prevention 2014 Asian Pacific journal of cancer prevention Vol.15 No.24

Background: This study aimed to understand the relationship between knowledge level and behavior on breast care in Chinese students, so as to provide strategies for improving the health education of breast care and subsequently for aiding in breast cancer prevention. Materials and Methods: A self-designed questionnaire was used to evaluate breast care knowledge level and characterize related behavior. Correlation analysis was conducted for the knowledge level and behavior. The study was carried out using 597 female undergraduate students in medical and non-medical colleges in Wuhu, China. Results: The average score of breast care knowledge was $5.32{\pm}1.68$ ($5.62{\pm}1.68$ and $5.00{\pm}1.68$ for medical and non-medical students, respectively), with a greater score value for sophomores ($5.59{\pm}1.72$) than freshmen ($5.18{\pm}1.65$). The average score of breast care behavior was $2.21{\pm}1.13$, again with a greater value in sophomores ($2.37{\pm}1.15$) than freshmen ($2.21{\pm}1.13$). A significant positive correlation (r=0.231, p<0.01) between knowledge scores and behavior scores was observed. In addition, various factors, including paying attention to breast care information, receiving breast self-examination guidance, TV program and Internet, were found to influence breast care knowledge. Conclusions: In general, female undergraduate students lack of self-awareness of breast care with a low rate of breast self-examination. It is necessary to carry out health education to improve early detection of breast cancer.

Observer-based Attitude Maneuver Control of Flexible Spacecraft: A Parametric Approach

Liu Zhang,Quan-Zhi Liu,Guo-Wei Fan,Xue-Ying Lv,Yu Gao,Yang Xiao 제어·로봇·시스템학회 2024 International Journal of Control, Automation, and Vol.22 No.7

To address the problem of control performance degradation caused by flexible attachment vibrations and external disturbances during attitude maneuvering of flexible spacecraft, this paper proposes a parametric method for improving flexible spacecraft attitude maneuver control (AMC) based on a functional observer. The objective was to enhance the control accuracy and disturbance rejection. First, state expansion was carried out for flexible spacecraft systems affected by disturbances. A functional observer was designed for the system, and sufficient conditions for the existence of the observer were obtained. Furthermore, a controller was designed by using the state information of the observer, which included state feedback and feed-forward compensation. Based on the parametric solution of a class of generalized Sylvester equations (GSEs), the parametric expressions of the controller and observer were established. Finally, a numerical example of a flexible spacecraft proved the effectiveness of the design method. The method can effectively suppress flexible vibrations and external disturbances while also meeting the high-precision control requirements of the flexible spacecraft.

Improving thermal shock and ablation resistance of high thermal conductivity carbon/carbon composites by introducing carbon nanotubes

Liu Xue-Song,Fu Qian-Gang,Wang Han-Hui,Tong Ming-De,Zhang Jia-Ping,Song Qiang 한국탄소학회 2020 Carbon Letters Vol.30 No.6

In order to improve the thermal shock and ablation resistance of high thermal conductivity carbon/carbon composites, carbon nanotubes (CNTs) were introduced by electrophoretic deposition. After modifcation, the fexural strength of the composites increases by 53.0% due to the greatly strengthened interfaces. During thermal shock between 1100 °C and room temperature for 30 times, the strength continues to increase, attributed to the weakened interfaces in favor of fber and CNT pull-out. By introducing CNTs at interfaces, thermal conductivity of the composites along the fber axial direction decreases and that along the fber radial direction increases. As the thermal shock process prolongs, since the carbon structure integrity of CNT and matrix in the modifed composites is improved, the conductivity increases whatever the orientation is, until the thermal stress causes too many defects. As for the anti-ablation performance, the mass ablation rates of the CNT-modifed composites with fbers parallel to and vertical to the fame decrease by 69.6% and 43.9% respectively, and the diference in the mass ablation rate related with fber orientations becomes much less. Such performance improvement could be ascribed to the reduced oxidative damage and the enhanced interfaces.

Elastography for Breast Cancer Diagnosis: a Useful Tool for Small and BI-RADS 4 Lesions

Liu, Xue-Jing,Zhu, Ying,Liu, Pei-Fang,Xu, Yi-Lin Asian Pacific Journal of Cancer Prevention 2014 Asian Pacific journal of cancer prevention Vol.15 No.24

The present study aimed at evaluating and comparing the diagnostic performance of B-mode ultrasound (US), elastography score (ES), and strain ratio (SR) for the differentiation of breast lesions. This retrospective study enrolled 431 lesions from 417 in-hospital patients. All patients were examined with both conventional ultrasound and elastography. Two experienced radiologists reviewed ultrasound and elasticity images. The histopathologic result obtained from ultrasound-guided core biopsy or operation excisions were used as the reference standard. Pathologic examination revealed 276 malignant lesions (64%) and 155 benign lesions (36%). A cut-off point of 4.15 (area under the curve, 0.891) allowed significant differentiation of malignant and benign lesions. ROC (receiver-operating characteristic) curves showed a higher value for combination of B-mode ultrasound and elastography for the diagnosis of breast lesions. Conventional ultrasound combined elastography showed high sensitivity, specificity, and accuracy for group II lesions (10mm<lesion diameter ${\leq}20mm$). Elastography combined with conventional ultrasound show high specificity and accuracy for differentiation of benign and malignant breast lesions. Elastography is particularly important for the diagnosis of BI-RADS 4 and small breast lesions.

한중 동물 속담의 문화적 의미 대조

Liu Xue Fei 한국어교육연구학회 2018 한국어교육연구 Vol.- No.9

옛날부터 동물과 인류는 관계(인연)를 깊이 맺어오고 있었기 때문에 인류의 생산과 생활 관계가 매우 밀접하다. 동시에 동물에 관한 속담은 오랫동안 민족의 정신문화에도 큰 영향을 미쳤다. 이번 논문에서는 한국과 중국의 동물에서 나타나는 출현 빈도가 높은 동물 속담을 조사하여 두 나라 사이의 언어와 문화이동 사례를 비교하고 분석해 보고자 한다. 한중 양국 동물에 관한 속담을 통해서 양국의 농사, 기후, 풍속, 생활습관과 욕 문화 등의 다양한 문화 차이를 볼 수 있다. 이를 통해서 또한 양국인의 사고방식과 언어 습관의 공통점과 차이점도 볼 수 있다. 본 논문은 한국어를 배우는 중국인, 중국어를 배우는 한국인에게 작은 도움이 될 수 있을 것이 바란다. 특히 오늘날과 같이 교류 현상이 두드러지고 있는 현실을 감안할 때에 이 연구의 필요성은 절실하다. Some of the Korean language norms, even if they are intended to be used by Korean users correctly, have a high incidence of the spelling errors due to the problem of regulation itself. An example is the more complicated and more cryptic rules by allowing different allomorph for forms that appear to have the same basic morpheme. Even if these regulations take maximum consideration of the characteristics of Korean language, there is a high possibility that the user will cause a spelling error from the beginning, compared to the simple rules. The purpose of this paper is to investigate the effect of the complexity of Korean language norms on the errors of the users spelling. In order to accomplish this purpose, this paper collected and analyzed errors in three types of morphemes which are spelled Korean users. As a result, the spelling error rate of Korean users was found to be very high. For example, in the case of ‘neolttarata’, the error rate is 211.8%, in the case of ‘subeol’, the error rate is 75%, in the case of ‘wicheung’, the error rate is 97.1%, compared to the correct spelling. This paper will be useful for revising related Korean language norms, which can improve the convenience and accuracy of spelling of Korean users in the future by verifying empirically the cases.

Generalized Stability Criterion for Multi-module Distributed DC System

Liu, Fangcheng,Liu, Jinjun,Zhang, Haodong,Xue, Danhong The Korean Institute of Power Electronics 2014 JOURNAL OF POWER ELECTRONICS Vol.14 No.1

The stability issues of a multi-module distributed DC power system without current-sharing loop are analyzed in this study. The physical understanding of the terminal characteristics of each sub-module is focused on. All the modules are divided into two groups based on the different terminal property types, namely, impedance (Z) and admittance (Y) types. The equivalent circuits of each group are established to analyze the stability issues, and the mathematical equations of the equivalent circuits are derived. A generalized criterion for multi-module distributed systems is proposed based on the stability criterion in a cascade system. The proposed criterion is independent of the power flow direction.
