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(P<0.05 or P<0.01), while those indices were significantly ameliorated in the H-IR group(P<0.05 or P<0.01). Higher levels of TNF-α, IL-1 and IL-6 in KCs were observed in the model group compared with the normal group(P<0.01). 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(P<0.05 or P<0.01). 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(P<0.01), while those expression levels in the L-IR and H-IR groups were significantly lower than the model group(P<0.05 or P<0.01). 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.展开更多

Methods SD male rats were randomly divided into five groups： normal, model, soothing liver recipe （SLR）, invigorating spleen recipe （ISR）, and soothing liver and invigorating spleen recipe （SLISR） groups. The rats in treatment groups were administered for 8 weeks. The liver tissue was stained with H＆E and oil red O. The levels of hepatic lipid and blood lipid were measured by biochemical analyzer. KCs were isolated from the livers of rats to evaluate the expression of LXRα, SREBP-1 C, and FAS mRNA by real-time fluorescence quantitative PCR tests; LXRα, SREBP-1C, and FAS proteins were measured by Western blotting. Results The H＆E and oil red O staining results showed that the model rats successfully reproduced typical pathogenetic and histopathological features of NAFLD. The levels of hepatic lipid and blood lipid in the model rats were dramatically increased. Compared with the model group, the values of hepatic lipid and blood lipid in the treatment groups were significantly ameliorated （P〈 0.05, 0.01 ）. The yields of purified KCs from each rat were 2×10^7-3×10^7. The viability of KCs was higher than 95%, with the purity over 90.18%. Compared with the model group, the expression of LXRα, SREBP-1C, and FAS mRNA and proteins was decreased in all treatment groups, especially in the SLR group （P〈 0.05）. Conclusion SLISR may protect liver against injury included by lipid metabolism disorders in KCs through LXRα/ SREBP-1 c signaling pathway, which may be an important mechanism for the prevention and treatment of NAFLD.展开更多

Methods: Three composite recipes were used on the 7- and 14-day corticosterone rat model to study the effect of recipes on the different patterns of immuno-modulatory and neuro- endocrinological systems. Results:The immune system of Spleen Invigorating(SI) group was well protected in either 7- or 14-day experiments,with the SI recipe showing no effect on the neuroendocrine system. It suggested that SI recipe might have direct action on immune system. On the other hand, KT group with no effect on neuroendocrine-immune (NEI) system in 7-day experiment, but showed a remarkable protective effect of the whole NEI system in 14-day experiment. Conclusion: The results indicated that KT recipe acts on the neuroendocrine system first, and then influence the immune system. It means that the action took place through down pathway of NEI network.展开更多
