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.

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.

OBJECTIVE To investigate the changes in and clinical significance of C-reactive protein(CRP) and endotoxin in patients who are firstly examined in fever clinic.METHODS To review and study the results of CRP and endotoxin from 81 patients(including 48 patients who were diagnosed as bacterial pneumonia and 33 patients who were diagnosed as a cold) in fever clinic of our hospital in 2005.RESULTS In 81 bacterial infection patients, the analysis indicated the levels of endotoxin between the pneumonia patients and the patients with a cold had significant difference.And the levels in the first group were significantly higher than in the latter one.The levels of CRP had no difference in two groups.CONCLUSIONS The result indicates plasma endotoxin detection helps to determine the early diagnosis of serious infection.It is also of significance to select antibacterial rationally and handle syndrome in time.In fever clinic,the levels of endotoxin may be a method to help diagnosis and treatment.CRP could be help to estimate the bacterial infection or virus infection,but it could not adjudge the seriousness in bacterial infection.

Lupus nephritis (LN) is a major cause of morbidity and mortality in patients with systemic lupus erythematosus.Although the use of aggressive immunosuppression has improved both patient and renal survival over the past several decades,the optimal treatment of LN remains challenging.The therapeutic strategy and progress for patients with lupus nephritis are based on the accumulative evidences of the medicine,and must be personalized according to the patient condition.This paper discusses established and newer treatment options for LN.We also emphasize the challenges in the day-to-day management of lupus nephritis in the clinical practice.

As a minimally invasive method of examination, magnetic resonance spectroscopy can provide information of brain metabolism and biochemistry, objectively reflect brain metabolite changes. Different manifestations were described in the diseases such as brain injury and brain tumor. As a result, magnetic resonance spectroscopy can be a helpful technology to give information of diagnosis and prognosis in neurosurgery for brain injury, brain tumor as well as brain abscess and epilepsy.

Age-related macular degeneration(AMD) is a macular disease and its incidence is gradually increasing with age.It is thought that its pathogenesis is related to the age,heredity,smoking,diet,oxidative stress,immune inflammation reaction and cardiovascular disease and so on.Oxidative stress is closely related to AMD.Antioxidant therapy provides a new strategy for the prevention and treatment of AMD.Also,it provides a new way to alleviate and prevent AMD.
