Objective: To investigate the mechanism of inflammatory-mediated toll-like receptor 4(TLR4)-p38 mitogen-activated protein kinase(p38 MAPK) pathway in Kupffer cells(KCs) of non-alcoholic steatohepatitis(NASH) rats and the intervention effect of soothing Gan(Liver) and invigorating Pi(Spleen) recipes on this pathway. Methods: After 1 week of acclimatization, 120 Sprague-Dawley male rats were randomly divided into 8 groups using a random number table(n=15 per group): normal group, model group, low-dose Chaihu Shugan Powder(柴胡疏肝散, CHSG) group(3.2 g/kg), high-dose CHSG group(9.6 g/kg), low-dose Shenling Baizhu Powder(参苓白术散, SLBZ) group(10 g/kg), high-dose SLBZ(30 g/kg) group, and low-and highdose integrated recipe(L-IR, H-IR) groups. All rats in the model and treatment groups were fed with a high-fat diet(HFD). The treatments were administrated by gastrogavage once daily and lasted for 26 weeks. The liver tissues were detected with hematoxylin-eosin(HE) and oil red O staining. Levels of liver lipids, serum lipids and transaminases were measured. KCs were isolated from the livers of rats to evaluate the mRNA expressions of TLR4 and p38 MAPK by real-time fluorescence quantitative polymerase chain reaction, and proteins expressions of TLR4, p-p38 MAPK and p38 MAPK by Western blot. Levels of inflammatory cytokines including tumor necrosis factor α(TNF-α), interleukin(IL)-1 and IL-6 in KCs were measured by enzyme-linked immunosorbent assay. Results: After 26 weeks of HFD feeding, HE and oil red O staining showed that the NASH model rats successfully reproduced typical pathogenesis and histopathological features. Compared with the normal group, the model group exhibited significant increases in body weight, liver weight, liver index, serum levels of total cholesterol(TC), triglyceride(TG), low-density lipoprotein cholesterol, and aspartate aminotransferase as well as TC and TG levels in liver tissues, and significant decrease in serum level of high-density lipoprotein cholesterol(P0.05 or P0.01), while those indices were significantly ameliorated in the H-IR group(P0.05 or P0.01). Higher levels of TNF-α, IL-1 and IL-6 in KCs were observed in the model group compared with the normal group(P0.01). Significant decreases in TNF-α, IL-1 and IL-6 were observed in the H-SLBZ, H-IR and L-IR groups compared with the model group(P0.05 or P0.01). The m RNA expressions of TLR4 and p38 MAPK and protein expressions of TLR4, p38 MAPK and p-p38 MAPK in KCs in the model group were significantly higher than the normal group(P0.01), while those expression levels in the L-IR and H-IR groups were significantly lower than the model group(P0.05 or P0.01). Conclusions: Inflammation in KCs might play an important role in the pathogenesis of NASH in rats. The data demonstrated the importance of TLR4-p38 MAPK signaling pathway in KCs for the anti-inflammatory effect of soothing Gan and invigorating Pi recipes. 相似文献

目的探讨美皮康敷料在ICU压疮高风险患者皮肤保护中的有效性。方法选取2015年1-6月入住我科的压疮高风险的1 030例患者作为干预组,对患者预防性地使用美皮康敷料;2014年7-12月入住我科未进行敷料预防性保护的压疮高风险974例患者作为对照组。比较两组压疮的发生情况。结果干预组与对照组相比,压疮的发生率从3.49%下降到1.94%,差异具有统计学意义(P=0.032);干预组出现压疮的风险比为0.409[95%CI(0.211,0.793)]。结论美皮康敷料能够有效预防ICU压疮高风险患者压疮的发生。 相似文献

The pathological changes of parasympathetic nerve are considered as an independent prognostic factor of the survival rate of patients with chronic liver disease. The non-selective muscarinic acetylcholine receptors (mAchR) agonists and antagonists can affect the proliferation of hepatocytes and hepatic stellate cells, but the subtypes of mAchR expressions in HCs are still uncertain. Here, we investigate the expression of mAchR in hepatic fibrosis on rats. 3 ml/kg 40% carbon tetrachloride (CCL4) was given to induce hepatic fibrosis on rats and the hepatocytes were isolated. Compared to the normal state, the expression levels of m1, 3, 5 in fibrotic liver tissues or hepatocytes were obviously increased, while m2, 4 decreased. 10 μM pilocarpine or 10 μM acetylcholine could increase the alanine aminotransferase (ALT), hydroxyproline (Hyp), collagen I, III in the hepatocytes, and decreased albumin (ALB). They also changed the expressions of mAchR similarly as the fibrotic hepatocytes and livers. However, atropine could ameliorate the state of fibrotic hepatocytes. These data indicate that mAchR played an important role in the regulation of hepatic fibrosis process. Targeting mAchR would have therapeutic potential for hepatic fibrosis. 相似文献
