Methods Sequence specific primers-polymerase chain reaction was used for the detection of genotypes and alleles of rs3850641 A/G loci in OX40L gene in 187 PACS cases (≤55 years) and 138 controls. Diseased vessel numbers and stenostic severity integral by coronary arteriogram and serum levels of sOX40L, C-reactive protein and vascular cell adhesion molecule-1 (VCAM-1) by enzyme-linked immunosorbent assay and nephelometry were measured. The relationship between OX4OL gene variants and PACS risk, SSI as well as plasma levels of three cytokines were analysed.

The models proposed, in addition to the VPC model proposed previously, include GAMM and GAMP for the modeling of manufacturing facility and process, respectively. The concepts of manufacturing capability for facility and process, as well as the mechanism for matching them, were also introduced into the proposed model. With these models, the knowledge of manufacturing facility and process for products with wide variations can be concisely represented for agile manufacturing execution control.

To disease resistance, SP3 (from H1) had stronger ability to resist leaf mold. 4.The characters obtained by space mutation were easier to be stable. The results showed that, the differences of the flowering dates of 1st inflorescence, the positions of 1st inflorescence, number of leaves between 1st and 2nd inflorescences in the colony were decreased with the development of generations. Most of these heritable characters could be stable in SP3 and a few could be stable in SP4, 2~3 generations earlier than that of traditional breeding (The characters were stable in 6 generations.).
