Hepatic fibrosis is a reparative response of diffuse over deposition and abnormal distribution of extracellular matrix (collagen, glycoprotein and proteoglycans) after exposure to various kinds of liver injuries, and is a key step in the developmental process of various chronic liver diseases to cirrhosis. Recently, many advances in our understanding of hepatic fibrosis have been recognized through the basic and clinical research. Therefore, we have organized the relevant domestic experts of this field to form consensus on the diagnosis and evaluation, treatment, and clinical development and application of therapy in order to better guide the diagnosis and treatment, and drug research and development.

Objective To study the effect and mechanism of pearl hydrolysate on hepatic sinusoidal capillarization in liver fibrosis. Methods Hepatic sinusoidal endothelial cells (HSEC) and hepatic stellate cells (HSC-LX2) were incubated with Hepu pearl hydrolysate.The proliferation of HSEC and HSC-LX2 was examined by MTT colorimetry.The cell cycle and apoptosis of HSC-LX2 were measured by flow cytometry.The changes of the microstructures such as fenestra and basement membrane of HSEC were observed by transmission electron microscopy. Results The intervention with leptin increased the viability of HSC-LX2 (P=0.041),decreased the viability of HSEC (P=0.004),and caused capillarization signs such as decreased number and diameter of fenestrae and formation of continuous basement membrane.The treatment with pearl hydrolysate at different doses increased and expanded the fenestrae of HSEC (low dose:P=0.020;medium dose:P=0.028;high dose:P=0.032),disintegrated the extracellular basement membrane of HSEC (low dose:P=0.020;medium dose:P=0.028;high dose:P=0.032),decreased the viability of HSC-LX2 (low dose:P=0.018;medium dose:P=0.013;high dose:P=0.009),and induced the apoptosis of HSC-LX2 (low dose:P=0.012;medium dose:P=0.006;high dose:P=0.005).Pearl hydrolysate exerted therapeutic effect on capillarization in a dose-dependent manner (low dose:P=0.020;medium dose:P=0.028;high dose:P=0.032).Moreover,high-dose pearl hydrolysate showed stronger effect on capillarization of hepatic sinuses than colchicine (P=0.034) and salvianolic acid B (P=0.038). Conclusion Hepu pearl hydrolysate can increase the viability of HSEC,restore the area of fenestrae,disintegrate the basement membrane,and decrease the viability and induce the apoptosis of HSC-LX2,demonstrating significant pharmacological effects on the capillarization of HSEC and HSC-LX2.
