Two types of circRNAs, hsa_circ_0000907 and hsa_circ_0057362, were selected as candidate biomarkers in current study and validated in a large cohort. The AUCs of serum hsa_circ_0000907 and hsa_circ_0057362 to diagnose early DFU were 0.9389 and 0.8792, respectively, and the AUCs of exosomal hsa_circ_0000907 and hsa_circ_0057362 to diagnose early DFU were 0.8783 and 0.8481, respectively. Furthermore, the expressions of serum hsa_circ_0000907 and hsa_circ_0057362 were negatively correlated with ankle brachial index (ABI) and transcutaneous oxygen pressure (TcPO2) in DFU patients. Serum and exosomal hsa_circ_0000907 and hsa_circ_0057362, especially hsa_circ_0000907, have novel diagnostic capabilities in the early diagnosis of DFU.

Profilin 1 (Pfn1) is likely to be involved in atherogenesis and myocardial infarction (MI). Clinical data on this subject are very limited. The aim of this study was to search for associations between serum Pfn1 and a number of parameters in MI patients symptom onset to PCI time (OPT), myocardial necrosis markers, thrombolysis in myocardial infarction (TIMI) flow, antiplatelet drugs, heparin administration and typical atherosclerosis risk factors. We included patients with type 1 MI (according to the Third Universal Definition of Myocardial Infarction) who were able to precisely determine the time of symptom onset. Exclusion criteria involved conditions potentially altering platelet function. We screened 114 patients and included 65. We assessed serum Pfn1 in three time points on admission (Pfn1_0), 24 hours post PCI (Pfn1_24) and 48 hours post PCI (Pfn1_48) and correlated it with OPT, cardiac necrosis markers (troponin T, CK, CKMB), TIMI flow in the infarct-related artery, pre-hospital P2Y12-antagonist aiabetes mellitus. Infiltration of the inflammatory cells, such as macrophages and myocardial necrosis, are involved in myocarditis. Insulin-like growth factor (IGF-1) exerts a variety of biological effects. However, the role of IGF-1 in myocarditis remains unclear. LDL-R knockout mice were randomly divided into the control group, myocarditis group, and IGF-1 siRNA group. Real Time-Polymerase Chain Reaction (PCR) and Western blot were used to measure IGF-1 expression in myocardial tissue. The myocardial tissue changes were analyzed by HE staining. The total cholesterol (TC) and low-density lipoprotein cholesterol (LDL) in each group were detected. Flow cytometry was used to analyze the number of macrophages. The secretion of TNF-α and INF-γ and macrophage migration inhibitory factor (MIF) were detected by enzyme-linked immunosorbent assay (ELISA). Compared with the control group, IGF-1 expression, TC, and LDL in myocarditis group was significantly increased, along with decreased heart rate (HR), left ventricular end-systolic diameter (LVEDs), left ventricular end-diastolic diameter (LVEDd), and left ventricular mass index (LVMI). In addition, inflammatory cell infiltration, fibrosis, and macrophages number in the peritoneum were increased. Moreover, the secretion of TNF-α, INF-γ, and MIF was also significantly increased (p<0.05). However, IGF-1 siRNA treatment inhibited IGF-1 expression and reversed the changes in the myocarditis group with statistically significant differences compared with the myocarditis group (p<0.05). IGF-1 expression is increased in myocarditis. The downregulation of IGF-1 expression inhibits macrophages infiltration, reduces the expression of MIF and inflammatory factors, and improves myocarditis injury.
