ABSTRACT

OBJECTIVE: To observe the levels of high mobility group box-1 protein (HMGB1), tumor necrosis factor-alpha (TNF-α), IL-6, troponin I (Tn I) release in septic rats, and to explore themechanism of Taohong Qinlian Decoction (TQD) in the treatment of septic myocardial injury. METHODS: A total of 48 healthy male Wistar rats of clean grade were randomly divided into the sham-operation group (Sham), the sepsis model group (CLP), and the TQD treatment group (ZY), 16 in each group. Concen-trations of TNF-α, IL-6, Tn I, and HMGB1 expression were detected in each group at 24 and 48 h after operation. Pathological changes of cardiac muscle were observed under light microscope. RESULTS: Concentrations of TNF-α, IL-6, Tn I and HMGB1 at 24 and 48 h after operation were significantly higher in the CLP group than in the Sham group (P < 0.01). Concentrations of TNF-α, IL-6, Tn I, and HMGB1 at 24 and 48 h after operation were significantly lower in the ZY group than in the CLP group (P < 0.05). Myocardial injury occurred in the CLP and the ZY group under light microscope. And this injury was more severe in the CLP group than in the ZY group. CONCLUSION: TQL could reduce the level of sepsis-related inflammatory cytokines and protect myocardium in septic rats.
