Objective: To compare the changes in the concentration of relevant growth factors released from platelet-rich plasma (PRP) stored at -80℃ by cryopreservation and at 4℃ by refrigerated lyophilization over 2 years, aiming to provide a theoretical basis for prolonging PRP storage duration. Methods: PRP (n=15) was separated using a blood cell separator and stored under -80℃ cryopreservation (F-PRP group) and 4℃ refrigerated freeze-drying conditions (FD-PRP group). The contents of growth factors (PDGF-AA, PDGF-BB, EGF, TGF-β1, and VEGF) in both groups were measured by ELISA at 1, 3, 6, 9, 12 and 24 months. Results: PDGF-AA and VEGF maintained good stability in both groups for up to 24 months. PDGF-BB and TGF-β1 showed high stability in the first 12 months but their stability decreased gradually from 12th to 24th months. EGF demonstrated good stability in the first 6 months, and its stability gradually decreased from the 9th to 24th months. Comparing the F-PRP and FD-PRP groups, the concentrations of the five growth factors in the FD-PRP group were either not statistically different or higher than those in the F-PRP group at all time points. Specifically, the concentrations of EGF were significantly higher in the FD-PRP group at all time points. Conclusion: Both -80℃ freezing and 4℃ freeze-drying enable long-term preservation of PRP. Freeze-drying imposes less stringent storage requirements and facilitates growth factor compared to frozen storage.

Objective To elucidate the therapeutic mechanism of Qingxin Jieyu Granule(QXJYG)against atherosclerosis(AS)based on network pharmacology.Methods The major targets and pathways of QXJYG against AS were analyzed using network pharmacology.Rat models of AS established by high-fat feeding combined with intraperitoneal vitamin D3 injection were treated daily with normal saline,atorvastatin(13.15 mg/kg),or QXJYG at 0.99,1.98,and 3.96 g/kg for 8 weeks(n=6).Ultrasound and HE staining were used to assess the function and pathologies of the abdominal aorta.Blood lipids and serum levels of Ang II,ET-1,TXA2,PGI2,and ox-LDL of the rats were detected using an automatic biochemical analyzer or ELISA.The expressions of LOX-1,PPARγ,RXRα,p-P65,VCAM-1 and ICAM-1 in the abdominal aorta were detected with immunohistochemistry.Results The rat models of AS showed obvious abdominal aorta wall thickening,increased pulse wave velocity and pulse index,decreased inner diameter of the abdominal aorta,elevated levels of TC,LDL-C,Ang II,ET-1 and TXA2,and lowered levels of HDL-C and PGI2.QXJYG and atorvastatin treatment of the rat models significantly alleviated histopathological changes of the abdominal aorta,decreased serum levels of TC,LDL-C,Ang II,ET-1 and TXA2,and increased the levels of HDL-C and PGI2.Network pharmacology study suggested the therapeutic effect of QXJYG against AS was mediated by regulating lipid metabolism,PPAR and NF-κB pathways.Consistently,treatments with QXJYG were found to significantly decrease ox-LDL level and LOX-1,P-P65,VCAM-1 and ICAM-1 protein expressions while increasing PPARγ and RXRα expressions in the aorta of AS rats.Conclusion QXJYG alleviates lipid metabolism disorder and improves histopathological changes of the abdominal aorta of AS rats possibly by lowering ox-LDL level,reducing LOX-1 expression,activating PPARγ and RXRα,and inhibiting P65 phosphorylation to reduce VCAM-1 and ICAM-1 expression in the aorta.
