Abstract: Some embodiments provide a method for forwarding data messages at multiple edge gateways of a logical network that process data messages between the logical network and an external network. At a first edge gateway, the method receives a data message, having an external address as a destination address, from the logical network. Based on the destination address, the method applies a default route to the data message that routes the data message to a second edge gateway and specifies a first output interface of the first edge gateway for the data message. After routing the data message, the method applies a stored NAT entry that (i) modifies a source address of the data message to be a public NAT address associated with the first edge gateway and (ii) redirects the modified data message to a second output interface of the first edge gateway instead of the first output interface.

Abstract: Some embodiments provide a method for forwarding data messages at multiple edge nodes of a logical network that process data messages between a logical network and an external network. At a particular one of the edge nodes, the method receives a data message sent from a source machine in the logical network. The method performs network address translation to translate a source network address of the data message corresponding to the source machine into an anycast network address that is shared among the edge nodes. The method sends the data message with the anycast network address as a source network address to the external network. Each edge node receives data messages from source machines in the logical network and translates the source addresses of the data messages into the same anycast public network address prior to sending the data messages to the external network.

Abstract: The present disclosure relates to use of a Clostridium ghonii spore combined with pembrolizumab in cancer treatment. It is found for the first time that the Clostridium ghonii spore combined with pembrolizumab can significantly improve a curative effect of colon cancer and reduce a dose of the pembrolizumab, and thus is efficient and low-toxic. Oncolysis by Clostridium ghonii can affect immunogenicity of a tumor microenvironment (TME) by various ways, converts an immunosuppressive state of the TME into an immune-activated state, adjusts the immunosuppressive TME, and breaks an immune tolerance. An optimal combination of the Clostridium ghonii spore and the pembrolizumab thoroughly removes about 20% of mouse tumor tissues. A benefit range of patients with tumors treated by a PD-1 antibody is expanded. The combination even has an obvious curative effect on patients failed the treatment by the PD-1 antibody.
