Objective: To study the scavenging capacity of extract from four kinds of barley leaves on superoxide free radical and hydroxyl free radical. Methods: Measure the content of superoxide free radical and hydroxyl free radical by nitro blue tetrazolium(NBT) photo-reduction. Results: Along with the flavonoid in the reaction liquid, the scavenging rate shows ascending trend . When the concentration of flavonoid is 12?g/ml, its scavenging rate is 95.56% and 94.12% on superoxide free radical and hydroxyl free radical respectively. Conclusion: The flavonoids of barley leave s have stronger anti-oxidative action.

AIM: To evaluate and analyze the morphological property and physiological activity of cartilaginous loose bodies in the knee joint, to research the changeable mechanism of histological morphous and physiological function. METHODS: The experiment was conducted at the Department of Pathology of the First Affiliated Hospital of Anhui Medical University, the Physical Testing & Chemical Analysis Center of Anhui Medical University, and the Electron Microscope Center of Anhui Provincial Hospital Affiliated to Anhui Medical University from January 2005 to January 2006. ①Experimental samples were 30 cartilaginous loose bodies all through arthroscopy as experimental group in which Group A (less than 6 months) had 14 samples and group B (between 6 and 12 months) 10, group C (more than 12 months) 6. Another 30 control samples were originated from non-weight loading side of articular cartilage through special equipment by arthroscopy. ②All samples were carried out the morphological measurement, light and transmission electron microscope exam, Ⅱ-collagen immunohistochemical stain, the measurement of collagen, calcium and fosforus. RESULTS: ①To compare the samples in the group A and control group, they had the identical or similar morphosis, microscopic structure of chondrocyte and distribution of extracellular matrix, the statistical treatments of the content of calcium, fosforus and collagen showed that the differences of scores between two groups were not statistically significant [calcium:(3.120?0.224),(3.090?0.231) mg/g;fosforus:(0.432?0.045),(0.455?0.067) mg/g;collagen:(462.43?17.12)(466.71?14.59) mg/g]. General speaking, comparing with the control articular cartilage, the loose bodies in group A had the normal histological property and physiological activity. ②Compared with control group, the samples in group B and C had the tendency of fibrous degeneration: necrotic or degenerative chondrocytes increasing, the contents of proteoglycan and Ⅱ-collagen decreasing, the tendency in group C more than group B, but the cartilaginous loose bodies in group B and C had many active chondrocytes mainly. Total content of collagen [(441.20?16.49),(417.33?8.38) mg/g] and Ⅱ-collagen decreased, while the contents of calcium and fosforus increased [calcium: (3.696?0.442),( 6.469?0.555) mg/g;fosforus:(0.523?0.068),(0.683?0.056) mg/g]. Generally, compared with the control articular cartilage, the histological property and physiological activity of the loose bodies in groups B and C had changed. CONCLUSION: The cartilaginous loose bodies can remain its histological property and physiological activity in the knee articular cavity for a long time, but it has the tendency of disorganization and physiological activity descending as time prolongs.

From genomics to proteomics, and then to miRNA, all without exception showed that proteins are the substance which directly regulate life. Comparing with genomics, the study of proteins is more difficult for its great variety, complicated modification and complicated construction. Recently, some new techniques for protein assay and research have provided us, for example, Fluorescence labeling, SELDI, SPR and optical protein chip, of which, SELDI SPR and optical protein chip are label-free. SELDI protein chip technique and its newly developed applications are briefly reviewed here.
