Abstract: A medical fluid container assembling system and method are disclosed. The system includes a coiled catheter pallet for receiving a catheter tip portion of a coiled catheter. The system also includes a coiled catheter preparation unit configured to place the coiled catheter on the coiled catheter pallet in a predetermined posture, and cause the catheter tip portion of the coiled catheter to extend a predetermined length. The system further includes a container body pallet for receiving a container tube of a container body. Additionally, the system includes a container body preparation unit configured to place the container body on the container body pallet in a predetermined posture, and cause the container tube of the container body to extend a predetermined length. The system also includes a container tube expander, a catheter tip gluing device, and an assembling mechanism configured to insert the catheter tip portion into the container tube.

Abstract: Embodiments of this application relate to the data access field, including data access methods systems that enable efficient and effective data access. In one embodiment, a method includes: assigning, by an RDMA control service based on user information and a corresponding connection relationship between a switch and a first instance defined by a user, an address segment to the first instance; building, by the RDMA control service, an access control list based on the address segment assigned to the first instance, where the access control list is used for controlling access between different first instances defined by the user; and sending, by the RDMA control service, the access control list to a switch control service, such that the switch control service configures the access control list for the switch.

Abstract: Provided are a PEG-naloxone conjugate of general formula (II) and a pharmaceutical composition comprising the conjugate. In the conjugate, n is an integer in the range of 1-20. Also provided is a three-branched or four-branched conjugate of PEG and naloxone. Structural modification of naloxone with a hydrophilic polymer improves the pharmacokinetic properties of the drug, increase the water solubility of naloxone, improve the in vivo distribution of the drug, reduce the side effects of naloxone on central nervous system, and relieve bowel dysfunction and constipation caused by chronic administration of opioids. Also provided are a pharmaceutical composition comprising the conjugate of the invention and use of the conjugate.
