We studied the protective effects of Qingyi decoction (QYD) (a Traditional Chinese Medicine) against severe acute pancreatitis (SAP)-induced myocardial infarction (MI).
To study the function and mechanism of QYD in the treatment of myocardial injuries induced by SAP.
Ultrasonic cardiography, hematoxylin and eosin staining, immunohistochemistry, qRT-PCR, western blot, enzyme-linked immunosorbent assays, and apoptosis staining techniques were used to determine the effects of QYD following SAP-induced MI in Sprague-Dawley rats.
Our SAP model showed severe myocardial histological abnormalities and marked differences in the symptoms, mortality rate, and ultrasonic cardiography outputs among the different groups compared to the control. The expression of serum cytokines [interleukin (IL)-1ß, IL-6, IL-8, IL-12, amyloid β, and tumor necrosis factor-α] were significantly higher in the SAP versus QYD treated group (P < 0.05 for all). STIM1 and Orai1 expression in myocardial tissue extracts were significantly decreased post QYD gavage (P < 0.001). There was no significant histological difference between the 2-aminoethyl diphenylborinate inhibitor and QYD groups. The SAP group had a significantly higher apoptosis index score compared to the QYD group (P < 0.001).
QYD conferred cardio-protection against SAP-induced MI by regulating myocardial-associated protein expression (STIM1 and Orai1).
Core tip: This manuscript illustrates the protective role of the Traditional Chinese Medicine, Qingyi decoction (QYD), on severe acute pancreatitis-induced myocardial injuries. QYD treatment was able to play a double role as a preventive and curative agent for both myocardial injuries and acute severe pancreatitis via the STIM1/Orai1-SOCE pathway. QYD treatment reduced myocardial injuries and the mortality rate by 30% in Sprague-Dawley (SD) rats within 24 h. Our findings reveal the success of QYD in improving the overall appearance of SD rats, together with decreasing the myocardial histological abnormalities and inflammatory cells infiltration caused by severe acute pancreatitis and myocardial injuries.
