Abstract:
Through comparative study on Naotaifang containing serum and plasma proteomics (peptide), this article revealed differential proteins (peptides) in the Naotaifang. The characteristics of differential proteins were identified with mass spectrometry. It provides scientific evidences for the pharmacodynamic material basis and Chinese herbal medicine plasma pharmacological method development in the exploration of Naotaifang. A total of 20 healthy adult SD rats were randomly divided into the control group, Naotaifang treatment group according to their weights. Ten rats in each group. Intragastric administration of medication was given for seven consecutive days. Before surgery, rats were fed with water but without food. One hour after the last drug administration, 10% chloral hydrate was injected for intraperitoneal anesthesia. Blood was taken through the common carotid artery. Serum and plasma samples were made after blood was taken from each rat. Serum and plasma samples of five rats were randomly selected from each group. And the two-dimensional electrophoresis (2-DE) technique was used in the comparative study of serum pro-teomics (peptide). The 300 DPI scanning and PDQuest 7.3.0 were used in the analysis. The ESI-MS/MS was used to identify important differences in proteins and screen characteristic serum and plasma protein. The results showed that 20 differential proteins of 5 plasma samples were identified. There were 15 types of proteins expressing up-regulation and 5 types expressing down-regulation. Comparative analysis on the 2-DE gel pictures of Naotaifang containing serum, 19 differential proteins of 5 plasma samples were identified, among which 15 types of proteins express up-regulation and 4 down-regulation. Comparative analysis on the 2-DE gel pictures of Naotaifang containing serum and Naotaifang containing plasma showed that 24 differential proteins of 5 plasma samples were identified, among which 9 types of proteins express up-regulation and 15 down-regulation. The highly expressed proteins were selected to MALDI-TOF-MS between Naotaifang containing serum and Naotaifang containing plasma. There were six successful-ly identified proteins, which were inter-alpha trypsin inhibitor, heavy chain 3, group-specific component, comple-ment factor B, Receptor Complexed with A Heterodimeric Fc, isoform CRA-d, Transferrin. It was concluded that protein with obvious changes in the Naotaifang containing serum and plasma may be related with fibrinolysis and an-ticoagulant. These proteins are involved in angiogenesis, inflammation and other pathological regulations of physiolog-ical processes. They are of great significance in the study of effective target and its signal transduction pathway of Naotaifang.
