OBJECTIVE To investigate the effect and potential mechanism of sodium ferulate (SF) on corneal endothelial dysfunction and corneal endothelial cell (CEC) injury. METHODS The male New Zealand rabbits were divided into control group, benzalkonium chloride (BAK) group and BAK+SF group, with 6 rabbits in each group. Except for control group, the other groups were given BAK into the anterior chamber to induce bullous keratopathy model, and BAK+SF group then given SF solution 200 mg/kg intraperitoneally the next day after surgery, twice a day, for consecutive 14 d. The transparency of corneal and edema of corneal stroma in each group of rabbits (before and on the 1st, 7th, and 14th day after surgery) were observed, and the corneal thickness (14th day after surgery) and intraocular pressure (1st to 14th day after surgery) were measured. On the 14th day after operation, the corneal endothelial structure was evaluated and the expressions of functionally related proteins [phalloidin, zonula occludens-1 (ZO-1), Na+/K+-ATPase, Ki67] were detected. On the 14th day after surgery, the corneal tissue was collected in BAK group, the primary rabbit CECs were isolated and cultured, and they were divided into blank group and SF groups with different mass concentrations. The cell viabilities after being cultured for different time, and the protein expressions of Ras homologous gene family A (RhoA), bone morphogenetic protein receptor 1A (BMPR1A) and BMRP2 were determined in each group. RESULTS Compared with BAK group, the transparency of corneal and edema of corneal stroma were gradually improved, and the corneal thickness was significantly decreased in BAK+SF group (P<0.05). The rabbit CECs in BAK+SF group were only damaged to zone B and showed a normal hexagonal endothelial cells structure. The protein expressions of phalloidin, ZO-1, Na+/K+-ATPase and Ki67 in BAK+SF group were significantly increased (P<0.05). When SF concentration was lower than and equal to 200 mg/L, it could promote the proliferation of rabbit CEC, in concentration manner (P<0.05) and time-dependent trend. SF at concentrations of 50, 100, and 200 mg/L could up-regulate the protein expressions of RhoA, BMPR1A and BMPR2 in concentration-dependent manner (P<0.05). CONCLUSIONS SF can improve the transparency of corneal and edema of corneal stroma in bullous keratopathy model rabbits, reduce corneal thickness, maintain the integrity of corneal endothelium structure, and promote the recovery of corneal endothelial function; this compound can promote the proliferation of CEC, the mechanism of which may be related to the activation of RhoA-ROCK-BMP pathway.

After hepatitis B virus (HBV) infects the body, HBV clearance and liver damage mediated by host immune response play a key role in clinical outcome. In chronic hepatitis B, the inflammatory response is a characteristic manifestation of the host immune response. The long-term inflammation promotes the development of liver fibrosis and cirrhosis. Innate immunity is the host’s first line of defense against hepatitis B virus infection, and plasmacytoid dendritic cells (pDCs) are a vital part of innate immunity and play a key role in chronic HBV infection, hepatitis occurrence, HBV clearance and recovery of infection. Exploring the function of plasmacytoid dendritic cells in chronic hepatitis B virus infection may provide a theoretical basis for clinical practice. In this article the research progress of the role of pDCs in the pathogenesis of chronic hepatitis B is reviewed.
