OBJECTIVE:To provide reference for the reform of the postgraduate training mode of pharmaceutical professional degree. METHODS:Domestic literatures about postgraduate training mode of pharmaceutical professional degree from 2010 to 2013 were searched and combined with the current education situation in China to conclude and summarize the existing problems and reform strategy. RESULTS:Postgraduate education mode of pharmaceutical professional degree in China was still in the explor-atory stage,with shortage of teachers,unreasonable courses,unsound educational structure,nonsupport of the students,imperfec-tion evaluation systems,and so on. Further promoting the reform of postgraduate education mode needs to strengthen teacher teams ’construction,implement cooperative training;improve training program and teaching courses;strengthen dissertation applica-tion-oriented and practice base construction;fully mobilize the enthusiasm and motivation of students;promote the connection of pharmaceutical professional training and vocational qualifications;and improve the quality assurance systems. CONCLUSIONS:Further implementation of postgraduate training mode of pharmaceutical professional degree and postgraduate education of pharma-ceutical professional degree can train the applied talents that meet social needs,improve employment rate of postgraduates and re-duce waste of educational resources.

Objective To investigate the relationship between fractional exhaled nitric oxide (FENO) and asthma predictive index (API) in infants under 3 years of age. Methods Totally 62 cases (under 3 years of age) who were hospitalized from June 2015 to June 2016 and had more than 3 times wheezing over the past year were enrolled in this study. They were divided into two groups according to API:API positive group with 37 cases and API negative group with 25 cases. FENO levels and peripheral blood eosinophil levels were detected and skin prick allergy test (inhalation and ingestion of allergens)was done in all selected children, did skin prick allergy test (inhalation and ingestion of allergens), simultaneous detected peripheral blood eosinophil levels. The parents of the children were investigated by questionnaire to know the children′ history about atopic dermatitis (such as urticaria, eczema, etc) and parents′ wheezing history. Above information was recorded and statistics analysis was made. Results There were no significant differences between two groups in atopic dermatitis inhalation and ingestion of allergens (P<0.01 or <0.05). The level of FENO in API positive group and API negative group was (16.70 ± 11.07), (13.52 ± 11.01) ppb(1 ppb=1 × 10- 9 mol/L), and there was significant difference (P<0.01). Conclusions There are associations between FENO and API, and they have good reference value in predicting the risk of asthma.

OBJECTIVE:To probe into the tendency and influencing factors of the drug expenses of the inpatients in our hospital.METHODS:The total drug expense,the antibiotic expense and its proportion in the total of the inpatients in our hospital were analyzed statistically in this retrospective study.RESULTS:During 2003～2007,the average daily total drug expense per inpatient was 371.77 yuan with average annual growth rate of 11.94%;the average daily antibiotics cost per inpatient was 110.35 yuan with average annual growth rate of 11.92%.Both the drug expense and antibiotic expense were correlated positively with the consumer price index (CPI).And the proportion of antibiotic expense in the total drug cost remained stable at about 29.68%.CONCLUSION:The average daily drug cost and antibiotic expenses per inpatient between 2003 and 2007 fluctuated yet with upward trend on the whole,and the proportion of antibiotic expense in the total drug cost remained stable.

OBJECTIVE:To design chinese unified bar code for drugs(BCD)with uniqueness and permenancy.METHO_ DS:Based on analysis of the status and problems of BCD used at present in China,the method and principle to standardize BCD were brought forward.RESULTS:The statistics indicated that most of the prescription drugs have no BCD labelled on the package and there is no unified drug identifying criterion adopted by pharmaceutical manufactures,therefore the depart?ment concerned should draw up unified BCD in China.CONCLUSION:Chinese unified BCD would be beneficial to scientific management of drugs and to ensure the safety of drug use.
