Atherosclerosis is a complex disease characterized by lipid accumulation in the vascular wall and influenced by multiple genetic and environmental factors. To understand the mechanisms of molecular regulation related to atherosclerosis better, a protein interaction network was constructed in the present study. Genes were collected in nucleotide database and interactions were downloaded from Biomolecular Object Network Database (BOND). The interactional data were imported into the software Cytoscape to construct the interaction network, and then the degree characteristics of the network were analyzed for Hub proteins. Statistical significance pathways and diseases were figured out by inputting Hub proteins to KOBAS2. 0. The complete pathway network related to atherosclerosis was constructed. The results identified a series of key genes related to atherosclerosis, which would be the potential promising drug targets for effective prevention.

【Objective】 To optimize the bottom and top(B&T) method for nucleated cell separation in cord blood in order to reduce the disturbance and improve the nucleated cell yield. 【Methods】 A new device comprised of two plastic plates and connection units was developed. B&T Cord blood bag was put between the plates, which were then centrifuged and put into the serum expresser together to go through serum and red blood cells separation simultaneously. After centrifugation parameter adjustment, the new Plates-B&T method was compared with traditional method in parallel. 【Results】 New Plates-B&T method could avoid buffy coat movement and disturbance. Compared to conventional PRP method, Plates-B&T method reduced centrifugation and separation time from(29.12±2.79)min to(14.91±2.12)min(P<0.05). Using new method, the recovery rate of total nucleated cell(TNC) was (89.04±5.19)%, the removal rate of red blood cell(RBC) was(55.56±22.57) %, and hematocrit(HCT) in buffy coat was(0.48±0.09)L/L. RBC removal was enhanced significantly, especially for cord blood samples with medium-low volume. 【Conclusion】 Based on B&T method, we established a new device and method, which increased the efficiency and quality of cord blood nucleated cell separation.
