Currently targeted therapy of breast cancer therapy has become the hot research field and a kind of brand-new biological treatment mode after three traditional pattern of the surgery, radiotherapy and chemotherapy for breast cancer. Molecular targeted therapy is aimed at the target that may cause cancer cells, such as protocarcinogenic genes and tumor-suppressor genes, cell signaling pathways, cytokines and receptors, antiangiogenesis etc. It can reverse malignant biology behavior to inhibit tumor cell growth from the molecular level and has the advantages of high specific effects and low side effects. This paper focuses on the drug of the molecular targeted therapy for breast cancer and the latest progress of targeted therapy.

Objective To establish the quality standard for Kangyuan Granula. Methods Radix Astragali, Radix Paeoniae Alba, Fructus Lycii and Radix et Rhizoma Glycyrrhizae in this prescription were identified by TLC. The content of the Paeoniflorin was determined by HPLC. The column of AichromBond-AQ-C18 (4.6 mm?150 mm, 5 ?m) was used, the mobile phase was Water-Acetonitrile (85∶15), at the flow of 1.0 mL/min, the column temperature of 30 ℃, and peaks were detected at 230 nm. Results The characteristic of identification by TLC was distinct and highly specific. The linear range of Paeoniflorin was 0.0545～0.545 ?g, r =0.999 5, the average recovery was 97.90%, RSD=1.06% (n =6). Conclusion The method was easy to operate with accurate result and good reproducibility. It can be used effectively for the quality control of this preparation.

OBJECTIVE: To establish a bacterial endotoxin test method for fluorescein sodium injection.METHODS: Based on the bacterial endotoxin test method stated in Chinese Pharmacopoeia 2005 edition(second part),an interference test was conduced on different batches of fluorescein sodium samples using tachypleus amebocyte lysate from different companies.RESULTS: At a concentration of no more than 0.75 mg?mL-1,fluorescein sodium showed no interfere with the bacterial endotoxin test.CONCLUSION: It is feasible for bacterial endotoxin test of fluorescein sodium injection be conducted in a limit value of 0.15 EU?mL-1.

Ischemic stroke is one of the major diseases of causing adult disability and death.Age,sex,smoking,hypertension,and diabetes,etc.are the risk factors for ischemic stroke,but they can only partially explain the reasons of stroke onset.Twins,families,and single-gene genetic stroke studies have shown that ischemic stroke has obvious genetic predisposition.In recent years,genomics has made remarkable progress in ischemic stroke study and has shown that many new single nucleotide polymorphisms or genes are associated with ischemic stroke and its risk factors.However,the contribution of these genetic genes for ischemic stroke is still too small and the repetitive studies are needed for further confirmation.

Medical institutes in the United States,the United Kingdom and Canada have systematically explored and published standard of physician competence,such as ACGME six-critical-components,GMC good medical practice and CanMEDS,which has led to changes in the content,item format and clinical skill test of foreign medical incensing exam.Foreign research inspires Chinese counterparts to study and develop the Chinese standard of physician competence so as to continuously enhance the medical licensing exam.

Putting emphasis on medical science education and looking down on medical humanistic education is the situation in medical colleges.Reasons of absence of medical humanistic education are as follows,one is the insufficient understanding of medical humanism and the other is the lack of practice.Learning traditional culture can make up for the deficiency of medical humanities education.Caring life and humanitarian spirit is the main value of traditional culture and expounding medical humanitarian spirit plays an important part in medical humanities education.Traditional culture education will cultivate student's virtue,open up the wisdom and construct the harmonious spiritual home.

OBJECTIVE:To provide reference for correct understanding and utilization of TCM injections. METHODS:Retrieved from recent literatures,ADR caused by TCM injection and utilization of TCM injection were analyzed to promote rational use of TCM injection. RESULTS & CONCLUSION:Research,production,circulation and utilization of TCM injection should be improved to make sure safety of drug use.

In the past decades, genetic lesions, aberrant epigenetic modifications, progenitor colonies formations and cell cycle distribution have been the focus of studies on the pathogenesis of primary myelofibrosis (PMF). The relative results showed that PMF is a clonal proliferative disease of hematopoietic stem cells. Now it is defined that primary myelofibrosis, polycythemia vera (PV) and essential thrombocythemia (ET) are chronic myeloprolfferative neoplasmas(CMPN).

[Summary] There is a huge population of adults with pre-diabetes in China ,and the majority of whom are impaired glucose tolerance(IGT) patients. IGT is not only a risk factor for type 2 diabetes ,but is also closely related to diabetic microvascular and macrovascular complications. Preventing or delaying the development of diabetes by intervention on IGT has become imperative. When lifestyle intervention alone cannot achieve the ideal goal of diabetes prevention ,pharmacological intervention should be considered. This review will discuss thepathophysiology of IGT ,and the effectiveness ,safety and pharmacoeconomics of IGT pharmacological intervention.
