Objective To research the Alzheimer disease(AD) patients' hippocampal structure and cognitive function with the susceptibility weighted imaging (SWI) and morphological measurement,and explore the changing regularity and correlation.Methods Sixty patients (divided equally into mild,moderate and major group as the condition of the severity of the AD) and 20 healthy control groups were scanned with SWI and T1MR,then the differences between AD and healthy controls were analyzed.Results The hippocampal volumes of AD patients were smaller than that of control group.The biggest variability occured in the major group(the left was Dunnett-t =-7.03,P ＜ 0.01 ;the right was Dunnett-t =-7.52,P ＜ 0.01),the moderate group was next(the left was Dunnett-t =-6.71,P ＜ 0.01 ; the right was Dunnett-t =-6.62,P ＜ 0.01) ;and the least variability occurred in the mild group.They did not achieve statistical significance (the left was Dunnett-t =-0.86,P＞ 0.05 ;the right was Dunnett-t =-0.68,P ＞ 0.05).The hippocampus vein' s length,diameter had reduced significantly in the mild group(Dunnett-t were-5.62,-7.02,P＜ 0.001),but the number of the branches was slightly increased,which was close to the statistical significance.(Dunnett-t =1.86,P ＞ 0.05).With the progress of the AD,all of the hippocampus vein's length,diameter,and branches were reduced significantly(the Dunnett-t of the moderate were-10.10,-11.40,-2.83,P＜0.05;the Dunnett-tofthe major were-11.69,-14.68,-5.74,P＜ 0.001).AD patients blood vessel diameter,length and cognitive have correlation(r =-0.034 ～-0.517,P ＜0.05,P ＜ 0.01).Conclusion The hippocampus vein and cognitive function function change in AD patients happened in the mild stages of disease.An important supplement to the MRI conventional sequences.

The assessments of oocyte quality were usually needed in assisted reproductive technology and reproduction science.Based upon the changes of structure and biochemistry in the development of oocyte,assessments of oocyte quality mainly comprised the oocyte morphology and its maturity.The assessment method of oocyte quality from nondestructive manner and invasive technique to provide multi-pathway for evaluating the oocyte quality reasonable was discussed.

Objective To explore the risk factors and protective factors for stomach cancer in Ganyu county.Methods Data of 319 pairs of new stomach cancer cases and health controls(1:1 matched)were studied by conditional Logistic regression method on the influential factors.Results The main risk factors for stomach cancer were the habits of eating hot foods(OR= 2.21,95%CI:1.57～3.12),the history of upper gastrointestinal inflammation(4.26,2.59～7.03),family history of cancer(2.29, 1.37～3.82);The main protective factors were often eating raw garlic(OR=0.64,95%CI:0.42～0.96),regular drinking tea(0.37, 0.25～0.54).Conclusion Unhealthy dietary habits,the history of upper gastrointestinal inflammation and family history of cancer are related to stomach cancer,while eating raw garlic and regular drinking tea may be effective in preventing the occurrence of stomach cancer.The results could be applied in stomach cancer prevention activities in Ganyu county.

Objective：To set up a system for the culture of Dendrobium chrysotoxum in vitro. Method：Tissue culture，fire fly luminescence and phenol-H2SO4 method. Result：The embryo could germinate with or without light, the MS, 1/2MS, B5, N6 mediums are suitable to the growth and the differentiation of sprout with light, 0.5　mg*L－1NAA and 1　mg*L－16-BA, and ATP have regular changes, the content of polysaccharide was 2.833% in plant and 7.254% in sprout. Conclusion：The light has no effects on the embryo germination, but the phytohormone，nitrogen source and organized elements are important to the growth and differentiation of the sprout which should be transferred to the MS, 1/2MS, B5, N6 mediums in time supplemented with NAA与6-BA, ATP may be served as the dynamic indication of nourishment demand in the plant. The content of polysaccharide in the sprout is higher and can be utilized.

Objective To study the life quality of 2 - 3 years old survivors in Neonatal Intensive Care Unit (NICU). Methods Severe neonates were randomly assigned to intervention group (group 1,30 cases) and non- intervention group (group 2,30 cases) depending on the early intervention applied or not,as well as 30 healthy newborns as normal controls. The physical,neurological conditions and intelligence test were taken regularly. To investigate the psychological state, actions, temperament and family conditions when they were2-3 years old.Results Mental development index(MDI) and physical development index(PDI) in early interventional group were significant higher than those in group 2(P
