Abstract: A packet processing method and system, and a network device are disclosed, and belong to the field of network technologies. A first network device sends a first packet to a second network device through a first tunnel, and sends a second packet to a third network device through a second tunnel. The second network device forwards the first packet to the third network device through a third tunnel. The third network device processes the first packet and the second packet. The first network device is located at a first site. The second network device and the third network device are located at a second site. The first site and the second site are connected through a wide area network. Wide area network multipath transmission may be implemented in a multi-gateway scenario.

Abstract: Provided are applications of an upstream Open Reading Frame (uORF) of a Phosphatase and Tensin homolog (PTEN) gene and a polypeptide coded by the same. A potential ORF of 96 bases (31aa-uORF) existing in the 5? UTR of the PTEN can code an oligopeptide of 31 amino acids (named PTEN-31aa) and plays an important role in the development and progression process of tumors. Provided is a new diagnostic and therapeutic method and a drug screening platform for PTEN expression regulation related diseases, in particular gliomas. Also provided is a polypeptide for treatment of PTEN expression regulation related diseases.

Abstract: The invention belongs to the field of research and development of genetic engineering antibody drugs, in particular, relates to a method for treating a tumor by administering Circ-CDH1. The Circ-CDH1 is a circular RNA Circ-CDH1 nucleic acid molecule or the protein Circ-CDH1-28 KD expressed by the circular RNA Circ-CDH1 nucleic acid molecule. In particular, a monoclonal antibody Anti-Circ-CDH1 is designed against Circ-CDH1-28 KD, which can specifically detect the content of a protein encoded by endogenous circular RNA Circ-CDH1, can remarkably inhibit invasion and metastasis of cells from tumors such as glioma, breast cancer and the like, and has wide application prospects in clinical detection of tumors and invasion and metastasis treatment.

Abstract: Provided are an upstream Open Reading Frame (uORF) of a Phosphatase and Tensin homolog (PTEN) gene and a protein coded by the uORF. A potential ORF of 138 bases (45aa-uORF) in the 5?UTR of the PTEN, coding an oligopeptide of 45 amino acids (named PTEN-45aa) plays an important role in the development and progression progress of tumors. Further provided are a new diagnostic and therapeutic method and a drug screening platform for PTEN expression regulation related diseases, in particular neuroglioma. Also provided is a polypeptide for treatment of PTEN expression regulation related diseases.
