Abstract: Disclosed in the embodiments of the present invention is a VPN server access method, comprising: acquiring an IP address assigned to a SIM card by a server at the network side, when dialing to the server at the network side is carried out successfully with the dial-up information built-in the SIM card; connecting to the proprietary VPN server automatically, if the acquired IP address of the SIM card belongs to the address segments of the proprietary VPN server. A VPN client is also disclosed in the embodiments of the present invention. With the present invention, the user experience can be improved.

Abstract: A synthetic device for cornea augmentation and replacement that increases corneal epithelium cell adhesion and migration. Using tethered extracellular matrix proteins (ECMPs), corneal growth factors, and other ligand-specific corneal enhancer species (e.g., laminin, fibronectin, substance P, fibronectin adhesion-promoting peptide sequence, FAP, and insulin-like growth factor-1 [IGF-1]) on the polymeric surface of an artificial cornea, the epithelial cell response can be significantly enhanced. Other proteins of interest include, but are not limited to, k-laminin, talin, integrin, kalinin, fibroblast growth factor (FGF), and TGF-&bgr;. By tethering a combination of corneal enhancer molecules, a more natural environment can be created.
