Traditional Chinese Medicinal Syndromes and Treatment in Colorectal Cancer  [PDF]
Shan Deng, Bing Hu, Hong-Mei An
Journal of Cancer Therapy (JCT) , 2012, DOI: 10.4236/jct.2012.326114
Abstract: Colorectal cancer remains the third most common malignancy worldwide. According to the principles of Traditional Chinese Medicine (TCM), colorectal cancer is related to spleen-deficiency, damp-heat, and toxicity accumulation. Traditional Chinese medicine has been confirmed to effectively reduce toxic side effects and enhance curative effects of chemotherapy, palliate clinical syndrome, prevent recurrence and metastasis, improve quality of life and immune function, and prolong survival time in colorectal cancer. However, TCM theoretical and syndrome differentiation study has lagged far behind due to progression of therapy model in colorectal cancer. As a type of drug treatment, there are some common biological basis between chemotherapy, targeted therapy and anti-cancer herb therapy in colorectal cancer, such as apoptosis, cell senescence and autophagy. There are growing needs to explore the effect mechanism and compatibility of anti-cancer herbs, to further enhance the efficacy of TCM treatment in colorectal cancer.

Abstract: An orthogonal test was used to optimize the reaction conditions of roasting zinc oxide ore using (NH4)2SO4. The optimized reaction conditions are defined as an (NH4)2SO4/zinc molar ratio of 1.4:1, a roasting temperature of 440°C, and a thermostatic time of 60 min. The molar ratio of (NH4)2SO4/zinc is the most predominant factor and the roasting temperature is the second significant factor that governs the zinc extraction. Thermogravimetric–differential thermal analysis was used for (NH4)2SO4 and zinc mixed in a molar ratio of 1.4:1 at the heating rates of 5, 10, 15, and 20 K·min?1. Two strong endothermic peaks indicate that the complex chemical reactions occur at approximately 290°C and 400°C. XRD analysis was employed to examine the transformations of mineral phases during roasting process. Kinetic parameters, including reaction apparent activation energy, reaction order, and frequency factor, were calculated by the Doyle–Ozawa and Kissinger methods. Corresponding to the two endothermic peaks, the kinetic equations were obtained.

Canadian Social Science , 2010,
Abstract: Metaphor in cognitive linguistics is not only a rhetorical device, but an important mental facility and cognitive instrument. Metaphors provide people a new perspective of perceiving the world and the application of cognitive theories of metaphor creates a new field of research to English teaching. After a brief analysis of the cognitive view on metaphor, this paper mainly focuses on how to apply the cognitive theories of metaphor to English language teaching. Key words: cognitive linguistics; metaphor; conceptual metaphor; English teaching
Empirical Analysis of Interactive Control’s Effectiveness: A Parent-Subsidiary Company’s Interdependence Perspective  [PDF]
Biao Luo, Jie-Jie Yu, Hong-Mei Ji
iBusiness (IB) , 2012, DOI: 10.4236/ib.2012.43025
Abstract: Due to the increasingly complex business environment and the principal-agent relationship, the enterprise group should establish a control system to prevent agency risk. Besides traditional system control, the parent company tends to adopt an interactive control including decentralized decision making, process communication and target incentive to guide and govern the subsidiaries. As an elastic control mechanism, the interactive control’s effectiveness could be influenced by the resources dependence relationship which is objective existence between the parent and subsidiary company. Based on the classical literature review, this study analyzes the effects of interaction control to the performance (“interactive control → performance”) and the interdependence’s regulating role by a total sample and a multiple-group structural equation analysis based on Chinese groups’ data, the results show that the interactive control could improve the subsidiaries’ performance, but different control process has its particular applicable interdependence situation. In the conclusions, we proposed some suggestions to promote the interactive control’s effectiveness in the enterprise group’s management practices.
The Construction of the Non-Material Incentive Model for the Firm Operator’s Compensation Contract in China  [PDF]
Biao Luo, Shan-Shan Zheng, Hong-Mei Ji, Chao Gong
Journal of Service Science and Management (JSSM) , 2012, DOI: 10.4236/jssm.2012.53035
Abstract: Effective compensation contract is the most driving force that encourages the operator of the firm to work hard. This article, considering the ability of the operator, built a model of compensation contract with some explanatory variables, such as effort level and risk attitude of the operator, coefficient of input flexibility, and coefficient of discount. Then, it tried to use the principal-agent theory to solve the model of explicit function, and analyzed the model based on material incentive and non-material incentive in the mechanism of profit sharing; the conclusion had important practical significance for the firm to implement the performance management.

American Journal of Operations Research (AJOR) , 2012, DOI: 10.4236/ajor.2012.24055
Abstract: This paper depends on the panel data of Anhui province and its 17 cities’ cigarette sales. First we established three single forecasting models (Holter-Wintel Season product model, Time series model decomposing model and Partial least square regression model), after getting the predicted value of cigarette sales from these single models, we then employ the combination forecasting method based on Time Series method and PLS to predict the province and its 17 cities’ cigarette sales of the next year. The results show that the accuracy of prediction is good which could provide a reliable reference to cigarette sales forecasting in Anhui province and its 17 cities.

Hong-Mei Jin,Ping Wei
International Journal of Molecular Sciences , 2011, DOI: 10.3390/ijms12084770
Abstract: Anti-fatigue properties of tartary buckwheat extracts (TBE) was investigated in male Kunming mice. The animals were divided into four groups. The first group, designated as the control group (control), was administered with distilled water by gavage every day for 28 days. The other three groups, designated as TBE treatment groups, were administered with TBE of 60, 120 and 240 mg/kg body weight, respectively, by gavage every day for 28 days. Exhaustive swimming time, blood lactic acid (BLA), blood urea nitrogen (BUN), tissue glycogen, glutathione peroxidase (GPx) and superoxide dismutase (SOD) of mice after swimming were determined. The results showed that tartary buckwheat extracts had anti-fatigue properties, which extended the exhaustive swimming time of mice, effectively inhibiting the increase of BLA, decreasing the level of BUN, increasing the tissue glycogen content and the activities of SOD and GPx of mice. However, further study is needed to elucidate the exact mechanism of the effect of TBE on fatigue.
