Non-alcoholic fatty liver disease (NAFLD) has become one of the major metabolic diseases.In view of the defects of traditional animal models, this study was the first to establish the NAFLD model of Mongolian gerbil (Meriones unguiculatus) with simple feed formula which is similar to human (from simple fatty liver to steatohepatitis, fibrosis,Liver cirrhosis).This study discussed the mechanism of rapid fatty liver deposition in Mongolian gerbil, revealed its molecular mechanism,main regulatory target and network function of fatty liver susceptibility.We provide a new animal model of NAFLD with relatively clear background and less time-consuming for clinical treatment and new drug development.The theoretical and practical basis for the breeding of inbred strain NAFLD gerbil was established.

Objective: To observe the promoting blood circulation by removing blood stasis of Lubai Capsule(LBC)(Rhizoma Phragmitis, Radix Paeoniae Alba, Radix Saposhnikoviae, Flos Schizonepetae, etc.). Methods: Acute blood stasis rat models were established with swimming in iced water and sc adrenalin in order to observe the effect of LBC on blood rheology. Mesenteric microcirculatory disturbance rat models were also established with adrenalin in order to observe the effect of LBC. Clotting time was measured in vitro with prothrombin time(PT) and kaolin partial thromboplastin time(KPTT) kit in order to observe its effects. Results: LBC could decrease the whole blood and plasma viscosity, fibrinogen, erythrocyte sedimentation and aggregation ratio of blood platelets of rats, ease the sticky condition of blood stasis rat models and prevent from forming thrombus. It could also inhibit the constraction and slowing of blood flow of thin artery, the reducing of open capillaries and change of fluid condition caused by adrenalin and improve these phenomena. PT and KPTT could be increased obviously. Conclusion: LBC can significantly promote blood circulation by removing blood stasis, because of improving blood rheology and mesenteric microcirculatory disturbance and inhibit endogenous and exogenous coagulation system.
