In each stage of life,people should pay attention to intaking the nutrients which is beneficial to preventing osteoprosis.

Morality and Ethics are rooted in the development of human society.Scientists should be strict with their professional morality and positively face ethics-related arguments.nowadays,based on the rapid development of Science &Technology,the relationship between science and society and the recognition of "self" have been changed fundamentally,which have caused new challenges to scientists in the fields of morality and ethics.

Objective To study the expression of Ki-67 in T1 primary breast cancer tissue and its relationship with Her-2 and ER,evaluate the prognosis of early breast cancer.Method s Sixty cases of women T1 primary breast cancer tissues of 60 female cases from January 2008 to June 2011 were selected.The expressions of Ki-67 were detected by immunohistochemieal method and the relationships between Ki-67 and clinical-pathological fcatures,Her-2 and ER were analysed.Results The expression of Ki-67 in T1 primary breast cancer was 55% among the 60 patients.The expression of Ki-67 was not related with the clinical-pathological type of breast cancer and menopause (P＞0.05).The expression of Ki-67 in group with lymph node metastasis was higer than in group without lymph node metastasis(P =0.047 ,P ＜0.05).The expression of Ki-67 in Her-2positive group was higher than Her-2 negative group (P= 0.021,P＜0.05),and the expression of Ki-67 in ER positive group was lower than that of ER negative group (P = 0.037,P ＜ 0.05).Conclusions The expression of Ki-67 in T1 primary breast cancer indicates the possibility of lymph node metastasis,and its positive correlation with Her-2 positive expression,ER negative expression indicates poor prognosis.

[Objective] The aim of this study is to investigate the mechanism and curative effect of cataplasma of Artemisia Argyi by supercritical CO 2 fluid extraction to rat weight, foot swel ing, interleukin-1β, interleukin-17 and tumor necrosis factor-αin the adjuvant arthritis rat models;and afford theoreti-cal evidence for clinical work.[Methods]50 healthy male SD rats were randomly divided into 5 groups:Control group, Model group, Low-dose treatment group, Medium-dose treatment group, High-dose treatment group. Model and al treatment goups took CFA for model ing. After establishing animal models of AA rats, the first group and second group used cataplasm without active drug ingredients. Other groups were given treatment according to dif-ferent drug doses. Assess the joint swel ing degree at different times. Measure the arthritic index and rat weight in two weeks. After 21 days ,detect the cy-tokines level of IL-lβ,IL-17 and TNF-α from the rat's serum and examine the pathological changes of joint observed by HE . [Results]Cataplasma of Artemisia Argyi by supercritical CO2 fluid extraction can significantly reduce rat foot swel ing of the ankle joint pathology ,reduce arthritis score and slow down the weight loss,meanwhile,effectively improve the general daily behavior of rats. The standard of IL-1β,IL-17,TNF-α in serum can be decreased by cataplasma of Artemisia Argyi by supercritical CO2 fluid extraction. The pathological result showed: in the treatment group,the rats synovial hyperplasia the vesselwing reduced, the inflammatory cel infiltration was more decreased than the model group. [Conclusion]The result showed that the cataplasma of Artemisia Argyi by supercritical CO2 fluid extraction had an obvious effect in treating RA. The mechanism was probably that it regulated the immune dis-order of RA.

As more attention is given to people's life and health,China continues to increase investment in scientific research to improve the level of medical research. However,the efficiency of the investment is unknown.In this study,we used the method of data envelopment analysis (DEA) to investigate the input-output relative efficiency of the projects funded by National Natural Science Foundation of China and completed in 2009 at 17 research institutes.We found 11 institutes to be DEA efficient,and 6 to be inefficient.It also showed that adjustment of research structure and setting performance objectives may improve the level of research management and increase the efficency of the investment.

ObjectiveTo retrospectively investigate the incidence,outcome and risk factors of HBV reactivation in HBsAg-positive a patients with gastric carcinoma during cisplatin-based adjuvant chemotherapy.Methods We retrospectively reviewed the records of 2,538 patients with gastric carcinoma who received adjuvant chemotherapy from January 2005 to December 2010.Among these patients,146 HBsAg-positive patients were analyzed for the HBV reactivation in this study.The HBV serology and biochemical tests of the 146 patients were performed.The data were analyzed by chisquare test.Results Among 146 HBsAg-positive patients with gastric carcinoma,43 patients (29.5％) developed hepatitis,of which 29 (19.9％) were related to HBV reactivation.Univariate analysis showed that age ≥51 years (P=0.029) and abnormal liver uhrasonography findings such as fatty liver or early cirrhotic changes (P=0.031) were associated with HBV reactivation.However,gender,HBeAg positive status and the use of corticosteroids were not related with HBV reactivation.Conclusions HBV reactivation occurs in a significant proportion of HBsAg-positive patients with gastric carcinoma during adjuvant cisplatin-based chemotherapy.Once hepatitis developed,most patients could not finish the chemotherapy as planned despite lamivudine treatment.Therefore,HBsAg-positive gastric carcinoma patients should initiate prophylactic antiviral treatment before chemotherapy.

Objective To explore the advantages and disadvantages of high quality care in clinical care. Methods 2000 cases of hospitalized patients from August 2010 to August 2011 in department of neurology were selected as research subject.The 2000 hospitalized patients were divided into the control group and the research group with 1000 cases in each group.The control group was given routine care,the research group selected high quality care.General activity of daily living (ADL) assessment and satisfaction degree of patients was surveyed at discharge for two groups and the results were compared. Results When patients were discharged,ADL scores and satisfaction degree of patients in the research group were higher than those of the control group. Conclusions Application of high quality care for patients can promote the improvement of activity of daily living and satisfaction degree of patients.

[Objective]To explore the professor Yu Tugen’s experience, in order to provide reference for clinical medication and the study of atopic der-matitis. [Methods] Treatment based on syndrome differentiation. First, through the analysis of etiology and pathogenesis and clinical manifestations of atopic dermatitis, it is divided into types, respectively analyze each type, discuss the experience in the treatment of various types; then give examples of the treat-ment experience of dampness heat syndromes, analysis of diagnosis and treatment system.[Result]Atopic dermatitis is divided into the types of damp-heat accumulation, spleen deficient aggregates the skin wet, wind formation from blood deficiency. After dialectical treatment, symptom is relieved.[Conclusion] This topic comprehensively summarizes the famous expert Yu Tugen ’s academic thought and clinical experience of atopic dermatitis of the types of damp-heat accumulation, provides a more complete treatment concept based on syndrome differentiation of TCM of atopic dermatitis, to relieve pain and improve the quality of life.

To a certain extent, itemized government subsidies to public hospitals, primarily used for hospital infra-structure and large equipment investments, can alleviate the financial pressure of development expenditures and thus re-duce the medical expenditure burden on patients. To test the hypothesis, the panel data method has been adopted based on the data of 23 tertiary hospitals. Empirical results find that:(1) increases in itemized subsidies will reduce the burden of medical expenses on patients;(2) conversely, the impact of itemized subsidies on outpatient medical expenses is more sig-nificant. By sharing a portion of public hospital expenses and impacting hospital service providing behavior, itemized sub-sidies help to reduce the burden of medical expenses on patients.
