The present study, therefore, aimed to investigate the underlying mechanism of the effects of TXD on CMD and determine its inhibitory effect on microvascular inflammation. However, the effects of TXD on CMD still remain unclear. The results of the recent study suggest that TXD alleviates inflammation and ameliorates the clinical symptoms of CHD. miltiorrhiza inhibits inflammatory responses and thrombosis in patients with thromboangiitis obliterans. rosea reduces neuroinflammation by regulating the Nrf2/NF- κB signalling pathway, and S. A recent study conducted by the authors of the present study found that TXD can increase the Nrf2 and downstream SOD expressions as well as reduce the expression of MDA in rats with CMD. TXD has been found to decrease the serum expression of IL-1 β and TNF- α in patients with CHD and decrease NF- κB protein expression in mice with atherosclerosis. Tianxiangdan (TXD) granules, a Chinese herbal compound composed of Rhodiola rosea, Ziziphora clinopodioides, Lignum dalbergiae odoriferae, and Salvia miltiorrhiza, have been used to prevent and treat CHD for over 30 years. Heme oxygenase-1 (HO-1), a downstream protein of the Nrf2 pathway, can decrease inflammation by inhibiting NF- κB transcriptional activity. In contrast, the proinflammatory effect of LPS can be inhibited by the activation of nuclear factor erythroid 2-related factor 2 (Nrf2). Moreover, lipopolysaccharide (LPS) can activate the nuclear factor- κB (NF- κB) pathway to upregulate inflammatory cytokines, such as tumor necrosis factor-alpha (TNF- α), interleukin (IL)-1 and IL-6. According to previous studies, an injection of sodium laurate into coronary microvessels can promote microvascular endothelial injury and microthrombus formation. Endothelial cells are the main regulators of vascular inflammation. Inflammation is an important pathological process in CMD it can injure coronary microvessels to promote thrombosis and perivascular fibrosis. However, current CMD treatments remain ineffective due to the disease’s complex pathogenesis. It is very common in patients with ischemia and nonobstructive coronary artery disease, with an incidence rate of approximately 60%. IntroductionĬoronary microvascular dysfunction (CMD), which is characterised by an abnormal structure and/or function of the coronary microvasculature (vessels with a diameter <500 μm), is a type of coronary heart disease (CHD). The results showed that TXD exerts a protective effect on rats with CMD and related inflammatory injuries, and its anti-inflammatory mechanism is related to the activation of Nrf2 signalling. However, the effects of TXD on CMECs were markedly reversed upon treatment with M元85 (Nrf2 inhibitor). In vitro experiments showed that TXD treatment increased the viability of LPS-induced CMECs and decreased the expression of IL-1 β, TNF- α, phosphorylated I κB α, and phosphorylated p65 ( ). These effects were more pronounced in the TXD-H group than in the TXD-M group. Compared with the rats in the untreated CMD group, rats in the TXD-M and TXD-H groups showed higher left ventricular ejection fraction values, improved pathological structures, decreased expressions of interleukin (IL)-1 β, tumor necrosis factor-alpha (TNF- α), phosphorylated nuclear factor- κB inhibitor α (I κB α) and phosphorylated p65, and increased expressions of nuclear factor erythroid 2-related factor 2 (Nrf2) and heme oxygenase-1 ( ). The effect of TXD on rats with CMD was observed after four weeks, and the mechanism of TXD in lipopolysaccharide (LPS)-induced cardiac microvascular endothelial cells (CMECs) was explored through treatment with 50 μg/mL TXD. d −1), and a nicorandil (NCR) group (1.35 mg.The rats were divided into six groups: a sham-operated (sham) group, an untreated CMD group, a low-dose TXD group (0.81 g Sodium laurate was injected into the left ventricle of Sprague–Dawley rats to induce CMD. A rat model of CMD was developed to study the mechanism of TXD activity. However, the underlying mechanism of TXD in coronary microvascular disease (CMD) remains unclear. Tianxiangdan (TXD) is used in traditional Chinese medicine because of its therapeutic and preventive effects in the treatment of coronary heart disease.
