Stromal cell-derived factor-1(SDF-1)is an early cell growth factor which belongs to a subfamily of chemokines.The CXCR4 is SDF-1 receptor.The SDF-1 interacting with CXCR4 plays important roles in physiological and pathological processes such as hematopiesis, stem cell homing,angiogenesis and leukemic cells infiltrating.To study the expression of CXCR4 in leukemia and the relationship between CXCR4 and leukemic cells infiltration can add indicators for leukemic MIC diagnosis of immunology indexes and have great significance to take molecule targeted therapy for preventing leukemia from infiltration or relapse as well.

In this paper, the authors analyzed the current problems in domestic hospital nursing human re-source such as widespread erosion, nursing staff slack and others. From the characteristics of nursing ethics and be-havior dynamic analysis, suggest to establish a focus on the humanities concern nursing ethics culture of the people-oriented, fundamentally effectively motivate nurses, specific include: respecting nurses and ethical personality differences;to establish a trust mechanism for nursing staff;meet the needs of nursing staff learning;to establish a nursing staff self management team, thus improve hospital nursing ethics management work, for the nursing staff to provide a stable and efficient working and living environment.

Tuo-Fawas one of three internal treatment rules in traditional Chinese medicine (TCM) surgery. It had been widely used in the treatment of superficial suppurative diseases, visceral suppurative diseases and other diseases. This article was aimed to clarify the action mechanism ofTuo-Fa for carrying forward better services in the clinic. This article reviewed and recapitulated related literatures on experimental researches ofTuo-Fa in recent years. It mainly showed the research status on anti-infection, anti-tumor and anti-gastric ulcer withTuo-Fa and its prescriptions. It summarized the existed shortcomings, which was that experimental researches on the action mechanism ofTuo-Fa was still on the initial stage with a few references and obviously lagged behind clinical applications. However, some achievements were also made. It had initially revealed the action mechanism ofTuo-Fa in treatment of pyogenic infection. It also had research on action mechanism of anti-tumor and anti-gastric ulcer treatment. It developed new field for the clinical practice. Finally, the research on action mechanism ofTuo-Fa and future prospects were expressed.
