ABSTRACT

Objective:By calculating the efficiency of the scientific research laboratory, which reflects the level of the scientific research input and output capacity, provide reference for the evaluation and decision-making of its scientific research sustainable development capacity.Methods:20 scientific research laboratories in a hospital were selected as the research subjects, annual input data were used as the input index. Weighted quantitative scores of the performance of each laboratory in research capacity and contribution, research team construction, discipline development and personnel training, operation management, papers and monographs, patents and transfer, awards, graduate-student training, standards and norms, and academic conferences. All these factors mentioned above were used as output indicators. Then Analytic Hierarchy Process (AHP) and Data Envelopment Analysis (DEA) are used to evaluate the scientific efficiency of each laboratory.Results:The performance of the laboratory is weak in the aspects of patent transfer, awards, standardization. The technical efficiency of laboratory 20 is the lowest, and the scale efficiency of laboratory 12 is the lowest.Conclusions:Scientific Research Laboratories should enhance the effectiveness through input adjustment and output enhancement, meanwhile each laboratory should pay attention to the transformation of scientific achievements and also the optimization of construction system.

ABSTRACT

Objective:To understand the statistics of SCI papers in hospitals of Shandong Province during 2009 to 2018.Methods:Web of Science was used to analyze the SCI papar information including the Annual publication volume change, source publications, research directions, collaboration institutions, counries and regions, funding institutions, conferences, as well as highly cited papers.Results:In the past ten years, 27 559 articles were published in total and kept increasling year by year, especially in 2011 to 2015 the uplift was about 30%-40%. All these papers were published in more than 2 700 journals. 23% papers were published in top 10 journals, whose Impact Factors were between 1-5. Papers in the field of oncology counted the most for 23.252%. Shandong University ranked NO.1 regarding collaboration instituions for it has many academically well performed affiliated hospitals as well asteaching hospitals. Doctors in Shandong Province cooperated a lot with the United States and other countries. 56.3% papers were financially assisted by various fundings and the National Natural Science Foundation of China predominated the most. 1 331 papers came from international conferences.There were 75 highly cited papers in the past 10 years.Conclusions:The quantity and quality of SCI papers were increased continuingly because of the guidance and promotion of scientific research policies, as well as the hospitals’ investments. It is necessary to emphasize on the high quality of scholar outputs and improve the scientific research management in the future.

ABSTRACT

Objective:Analyze and discuss the research situation and hot topics of Chinese medical science research management in the past ten years, provide reference for the managers in this field.Methods:Using Excel and CiteSpace to analyze the papers on medical science research management in Wanfang Med Online, information about the journals, institutions, authors, hot topics and frontier related data was analyzed.Results:There are 2176 valid records in total, among which the most was recorded in 2012, these paper were mainly published in the " Chinese Medical Science Research Management" , up to 187, accounting for 8.6% of the total. The institutions of paper publication are ranked in the following order: Peking Union Medical College Hospital, Academy of Military Medical Sciences, Peking University, Capital Medical University, Sichuan Provincial People's Hospital. The authors who have published more articles include Liu Yan, He Youqin, Yan Junxia, Zhang Huanping, Niu Yuhong and so on.Conclusions:Authors within the same institution have close cooperation and there is less cooperation among different institutions. This paper briefly discusses the more researched aspects of medical science research management, evaluation index system, scientific research personnel training, data mining and system design.

ABSTRACT

OBJECTIVE:To study the anti-coagulation effect and mechanism of fibrinolytic enzyme SNFE in sipuculus nudus, and provide reference for further development of SNFE. METHODS:40 mice were randomly divided into blank control group(nor-mal saline),Xueshuantong group(positive control,15 mg/kg)and SNFE low-dose,high-dose group(15,30 mg/kg),10 in each group. After intravenous injection in tail,tail bleeding time (BT) and clotting time (CT) were respectively determined to investi-gate the anti-coagulation effect of SNFE. After taking blood in abdominal aorta of rats,test was divided into blank control group, positive control group and SNFE low-mass concentration,medium-mass concentration,high-mass concentration groups (0.25, 0.50,1.00 mg/mL). Prothrombin time(PT),re-calcium time(PRT)(using orokinase as positive drug,100000 U/mL),and max-mum platelet aggregation rate (PAG) in 5 min under adenosine diphosphate (ADP) inducer (using asprin as positive drug,0.50 mg/mL) were respectively determined,and anti-coagulation effect mechanism of SNFE was analyzed. RESULTS:Compared with blank control group,BT,CT of mice in each group were prolonged,with statistical significance in Xueshuantong group and SNFE high-dose group (P<0.05 or P<0.01). Plasma PT of rats in positive control group,SNFE medium-dose,high-dose groups and PRT in each administration group were significantly prolonged(P<0.05 or P<0.01);and PAG in administration group was signifi-cantly reduced(P<0.01). CONCLUSIONS:The fibrinolytic enzyme SNFE in sipuculus nudus can play its anti-coagulant effect by inhibiting the activity of coagulation factors in internal and external sources and ADP-induced platelet aggregation.

ABSTRACT

OBJECTIVE:To study the anti-oxidative effects of spirulina kinase (SPK) in vitro. METHODS:The methods of phenanthroine-Fe2+ oxidation method,DPPH and auto-oxidation of pyrogallol were used to measure the effects of different concen-trations of SPK on scavenging hydroxyl (OH-) free radical,DPPH free radical and superoxide anion (O2-) free radical;IC50 of SPK was calculated. Prussian blue reaction was used to determine total reducing ability(by absorbance)of different concentrations of SPK to Fe3+. Vitamin C(VC)was used as positive control in above trials. RESULTS:SPK could eliminate the OH-free radical, DPPH free radical and O2- free radical in concentration-dependant manner,and the maximum elimination rate of SPK to OH- free radical and DPPH free radical were 86.82% and 78.98%(IC50 were 54.31,0.636 g/L),which were higher than VC (64.77%, 73.49%). The maximum elimination rate of SPK to O2- free radical was 78.31%(IC50 was 3.918 g/L),which was lower than VC (94.14%). In reducing ability test,SPK improved absorbance in reducing ability test system,and maximum absorbance was simi-lar to VC in concentration-dependant manner. CONCLUSIONS:SPK has obvious anti-oxidant activities in vitro.
