Abstract: The disclosure of the present application relates to a secretory deleted split hand/split foot 1 (sDSS1) protein, the amino acid sequence thereof, the nucleic acid sequence thereof, and the applications of the same. The sDSS1 protein is a secretory protein from higher primate, and can be detected in human serum and cerebral spinal fluid (CSF). The sDSS1 protein can form conjugate with oxidized protein under nonenzymatic condition or with amyloid-beta (A?) polypeptide to reduce formation of A? oligomer. The addition of sDSS1 protein to culture medium can shield the cytotoxicity induced by oxidized protein, A? oligomer, amylin oligomer and glycosylated protein, so as to protect the cells against these toxoproteins. The sDSS1 protein can prolong survival time of senescence-accelerated mice significantly.

Abstract: The present disclosure discloses a system, a method and an apparatus of data interaction under load balancing to solve the problem of heavy workload of a server load balancer under existing technologies. The system includes a server load balancer, a real server, and a conversion apparatus. A data package, which is sent from a client to a real server, is processed and sent by the server load balancer to the real server. A data package, which is sent from the real server to the client, is processed and sent by the conversion apparatus to the client. Since the traffic flowing from the real server to the client does not pass through the server load balancer but is processed and sent by the conversion apparatus to the client in the above system that is provided by the embodiments of the present disclosure, the workload on the server load balancer is thus effectively reduced.
