1.Evaluation of research level of medical institutions by SCI papers
Chinese Journal of Medical Science Research Management 2008;21(3):171-172
The publication and citation of academic papers are important indexes to evaluate science research level of colleges and institutes and also important index to evaluate researchers. In this paper we calculated and analyzed the number of publications, cited number, and cited frequency of SCI papers in three military medical universities and one military medical research institution from 1997 to 2006, and put forward some opinions and suggestions.
2.Determination of Total Flavonoids and Quercetrin in Different Parts of Apocynum venetum from Songnen Grassland & Its Antioxidant Activity
China Pharmacy 2007;0(33):-
OBJECTIVE: To determine the contents of total flavonoids and quercetin in different parts of Apocynum venetum collected in Songnen grassland and study their antioxidant activities so as to provide references for efficient utilization of the herbal plant.METHODS: Ultrasonic extraction was applied to extract total flavonoids.The content of total flavonoids was determined by chromatometry and the content of quercetin was determined by HPLC.The antioxidant activities of the extracts from different parts of A.venetum were evaluated by determining their abilities in scavenging 1,1-diphenyl-2-picrylhydrazyl(DPPH?) radicals and?OH radicals.RESULTS: The contents of quercetin and total flavonoids were richer in both leaves and flowers of A.venetum than in stems.In addition,the total flavonoids extracted from the leaves and flowers of A.venetum showed higher antioxidant activity than from the stems.CONCLUSION: The leaves,flowers and stems of A.venetum can all be used as raw materials of natural antioxidants.
3.Review on college of nursing of Michigan State University
Chinese Journal of Medical Education Research 2011;10(2):135-137
Through the review on the 2 months visit to College of Nursing of Michigan State University,I'd like to share the ideas with others.The conten of nursing education,clinical nursing,nursing research and patient safety to improve quality of nursing education.
4.DNA methylation and atherosclerosis
International Journal of Cerebrovascular Diseases 2011;19(2):151-156
Atherosclerosis is the outcome of polygenic inheritance and interaction of environmental factors.It is one of the important the diseases controlled by the epigenetic laws.DNA methylation is the first discovered and well-studied epigenetic molecular mechanism.There are a variety of ways for the detection of DNA methylation,each has its advantages and disadvantages.The abnormal methylation modification of genomic DNA comprehensive hypomethylation and related candidate genes is closely associated with the occurrence and development of atherosclerosis.This article reviews the related research progress.

Purpose:Balloon catheter dilation was performed in 4 young infants with anas- tomotic esophageal strictures.To discuss the method of balloon dilation and evaluation of successful. Materials and Methods:The 4 cases had an anastomotic stricture after surgical correction of esophageal atresia.Their age range was 2 to 15 months.Each case had a barium esophagram before balloon dilation.The diameter of esophageal stricture ranged from 3 to 6mm.The balloon size from 3 to 15mm in diameter.Results:All of the 4 cases complete resolution of the strictures was achieved after 1 to 4 dilations.There was no esophageal perforation.Conclution:Balloon catheter dilation presented in the paper is a simple,safe and reliable one for the treatment of anastomotic esophageal stricture in young infant as first choice treatment.
7.The application of bioelectrical impedance measurement of body composition in patients with liver diseases
Parenteral & Enteral Nutrition 1997;0(04):-
The status of bioelectrical impedance measurement especially the multifrequency segmental bioelectrical impedance measurement of liver diseases is introduced.The multifrequency segmental bioelectrical impedance can well rule out the impact from the change of body weight caused by edema and ascites,and can evaluate the volume of ascites.Compared with single frequency bioelectrical impedance,the multi frequency bioelectrical impedance measurements probably display good prospect.It helps to produce objective judgement on nutrition status and energy metabolism for patients with liver diseases.The effect,however,needs further clinical research.
9.Evaluation of the early prediction score system for multiple organ dysfunction syndrome in the elderly
Chinese Journal of General Practitioners 2011;10(3):175-177
Objective To evaluate the early prediction score system for multiple organ dysfunction syndrome in the elderly (MODSE) induced by pulmonary infection. Methods A total of 316 patients with pulmonary infection aged over 60 were admitted from 2007 Jun to 2009 Jun. All patients were scored by the early prediction score system for MODSE and then classified as high-risk group and non high-risk group. χ2 test was used to analyze the difference in morbidity of MODSE between high-risk group and non high-risk group. Receiver operating characteristic (ROC) curve was drawn, and the area under the curve, sensitivity and specificity was calculated. Results The morbidity of MODSE in high-risk group was higher than that in non high-risk group(χ2=87.569,P<0.01).The area under the ROC curve was 0.864(P<0.01).The sensitivity and specificity of the early prediction score system of MODSE were 84.2% and 72. 1%, respectively. Conclusion The early prediction score system for MODSE can be used to predict MODSE induced by pulmonary infection and to screen for the high risk population.
10.FRESH WATER FISH OIL OF CHINAV. DETERMINATION OF CHOLESTEROL IN FRESH WATER FISH OIL EMULSION
Chinese Journal of Marine Drugs 1994;0(03):-
In this study,cholesterol content of fresh water fish oil emulsion was determined by gas chromatography. It was 30g/L and was lower than that in other marine fish oil preparations. The regression equation of standard curve was Y=1. 855x-6. 3467 ,and correlation coefficient was 0. 9990. The recovery rate ranged from 84.0% to 97. 0% ,and CV = 7.1%.
