Ever greater attention has been paid to the role of Chinese herbal monomers and compounds on wound healing. This study aims to elucidate the wound healing mechanism of Modified Hongyu Decoction (MHD) in vivo and in vitro. MHD wound healing activity in vivo was evaluated using an excision rat model. H and E staining, Masson's staining and immunofluorescence of wound tissue on days 7 and 14 were performed to evaluate the efficacy of MHD on wound healing. Subsequently, human umbilical vein endothelial cells (HUVECs) were used to evaluate wound healing characteristics in vitro. Cell Counting Kit-8 (CCK-8) and scratch assays were conducted to assess the effects of MHD on the proliferation and migration of HUVECs. The involvement of the VEGF/PI3K/Akt signaling pathway was assessed by western blotting. The rats in the MHD group displayed more neovascularization and collagen fibers. Western blotting of wound tissue showed that VEGF, PI3K, p-Akt and p-eNOS expression were significantly increased (p<0.05) in the MHD group. Cell Counting Kit-8 and scratch assays demonstrated that MHD promoted HUVECs proliferation and migration. MHD treatment significantly increased VEGF, PI3K, p-Akt and p-eNOS expression in HUVECs (p<0.05), which was inhibited by LY294002.

It was also shown that forming prothrombin complexes with E- or DDE-fragments causes non-enzymatic prothrombin activation. The direct measuring of the prothrombin level in the blood plasma of patients with acute myocardial infarction (AMI) allowed us to find a situation where such an activation can occur in vivo. Blood coagulation parameters in the blood plasma of patients with AMI were measured at 2 hours, three days, and seven days after the thrombolysis by streptokinase accompanied with intravenous administration of anticoagulants: unfractionated high molecular weight heparin (HMWH) and low-molecular-weight heparin (LMWH). The prothrombin level in the blood plasma of patients with AMI was normal before thrombolytic therapy and substantially decreased after streptokinase administration. This effect was prominent in the case of concomitant anticoagulant therapy with LMWH and was not observed when HMWH was applied. It can be explained by the fact that LMWH preferentially inhibits factor Xa, while the HMWH is an effective inhibitor of both factor Xa and thrombin. This observation suggested that the prothrombin level decrease was caused by the thrombin-like activity and possible autolysis of prothrombin by thrombin. Also, thrombolytic therapy with streptokinase caused the accumulation of fibrin degradation products (FDPs), some of which were able to bind prothrombin. The dramatic decrease of prothrombin level in the blood plasma of patients with AMI during thrombolysis allowed us to conclude the non-enzymatic prothrombin activation with the following autolysis of prothrombin that contributes to the pathology.</p>","PeriodicalId":6984,"journal":{"name":"Acta biochimica Polonica","volume":" ","pages":"991-995"},"PeriodicalIF":1.7,"publicationDate":"2023-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138443511","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
