The camptothecin derivatives have high solubility, the anticancer drugs prepared from them have the advantages of wide anticancer spectrum and high safety, and have in vivo anticancer activity higher than irinotecan hydrochloride.

Abstract: A projection module includes a light source, a reflective structure, and an optical structure. The light source emits laser light. The reflective structure includes a first reflective element and a second reflective element. The optical structure includes a first optical element and a second optical element. The reflective structure is disposed between the laser source and the optical structure. The first reflective element reflects a portion of the laser light towards the second reflective element, and transmits a remaining portion of the laser light towards the second optical element. The second reflective element reflects the laser light from the first reflective element towards the first optical element. The first optical element and the second optical element cooperatively project the laser beam towards an object.

Abstract: An electrical plug connector includes a metallic shell, an insulated housing in the metallic shell, plug terminals held in the insulated housing, and a hook member. Hook portions of the hook member extend into the insertion cavity of the insulated housing. Each hook portion forms a first positioning portion and a second positioning portion. When the electrical plug connector is mated with an electrical receptacle connector, the electrical plug connector can be positioned with the electrical receptacle connector through multiple contacts, thereby preventing the electrical plug connector from shaking.

Abstract: A system and method for providing cryptographic operation service in a virtualization environment. In the system, a configuration subsystem provides an interface for an administrator and a common user to input information about a virtual cryptographic device. A key file storage subsystem stores a key file and protects it with the protection password. A virtual machine operating subsystem obtains a corresponding key file from the storage subsystem according to the input of the configuration subsystem, creates a virtual device for a guest virtual machine, and finally operates the guest virtual machine to provide cryptographic computing service for the guest virtual machine. Thus the administrator/the common user can specify a key file and input a protection password for a guest virtual machine via the corresponding interface to facilitate the creation of a virtual cryptographic device, and can manage the virtual cryptographic device in a user-friendly and centralized manner.
