  • Objective : Methods of Jang Cong-zheng's treatment related to his theories include of promoting the sweating-vomiting-purgation(汗吐下三法), prickling-bleeding method(瀉血療法), and emotional therapy(情志療法). He succeeded Liu wan-su(劉完素) as promoter of fire-heat pattern theory(火熱論), thereby emphasizing six qi(六氣), especially fire(火) and dampness(濕), as pathogens. He suggested that physician should treat patients whose diseases occurred due to fire(火) and dampness(濕) with promoting the sweating(汗)-vomiting(吐)-purgation(下) methods, which would remove pathogen qi(邪氣) and help circulation of qi and blood, therefore getting them back healthy qi(正氣). Method : I will try to describe the Jang Cong-zheng's treatment in "Ru-Men-Shi-Qin", and I would like to explain the sweating-vomiting-purgation(汗吐下三法), prickling-bleeding method(瀉血療法), and emotional therapy(情志療法). Result : For emotional diseases, he suggested that most should be caused by heart fire(心火) so they should be treated with methods of suppressing heart fire and medication would be using cool and cold herbal drugs which lead to clear heart fire. Conclusion : Theories of Zhang zi-he(張子和) can be applied to nurturing for modern world maintaining and improving health by his care methods. People these days suffer usually from excess intake or unbalanced diet problem, so wastes matter and pathogenic qi can be driven out of the human body by applying the sweating-vomiting-purgation methods. His medical theories could contribute to modernization of traditional medicine this way.

  • In this paper, we introduce an adaptive phase-comparison monopulse technique for angle estimation of two targets in the same antenna beam. The proposed method determines a more suitable technique(between conventional phase comparison monopulse technique and Zheng's method) based on interference between two targets in Fourier domain. Consequently, regardless of the interference, angles of each individual target can be accurately estimated by means of the proposed method. In simulations, we assumed that two point targets with same velocity are located in the same antenna beam, and the accuracy improvement of the proposed method is verified by using several simulations.

  • The association between the NAD(P)H:quinone oxidoreductase 1 (NQO1) gene C609T polymorphism (rs1800566) and gastric cancer has been widely evaluated, but a definitive answer is so far lacking. We first conducted a case-control study to assess this association in a large Han Chinese population, and then performed a meta-analysis to further address this issue. Although our case-control association study indicated no significant difference in the genotype and allele distributions of C609T polymorphism between gastric cancer patients and controls, in the meta analysis involving 4,000 subjects, comparison of alleles 609T and 609C indicated a significantly increased risk (46%) for gastric cancer (95% confidence interval (95%CI) for odds ratio (OR)=1.20-1.79) in individuals with the T allele. The tendency was similar to the homozygote (OR=1.81, 95%CI: 1.16-2.84), dominant models (OR=1.41, 95%CI: 1.12-1.79), as well as recessive model (OR=1.58, 95%CI: 1.06-2.35). Stratified analysis by study design demonstrated stronger associations in population-based than in hospital-based studies. And ethnicity-based analysis demonstrated a significant association in Asians. We conclude that the NQO1 gene C609T polymorphism increases the risk for gastric cancer, especially in Asian populations.
