The invention provides a method, a system and a network device for filtration. The method comprises the following steps: intercepting a request message transmitted by a user terminal to an internet server and extracting uniform resource locator (URL) information from the request message; determining a security level corresponding to the URL information according to the URL information; and processing the request message according to the security level. The invention solves the problems that internal memory space and CPU resources are occupied by anti-virus software installed on the user terminal, avoids the risks that malicious software can easily bypass the anti-virus software, effectively stops the propagation and the attack of the malicious software, reduces the threat of the malicious software to the user terminal and improves the network security and the user experience.

Described herein are platinum-based brush-arm star polymers (Pt-BASPs), or a pharmaceutical composition thereof, for delivery of platinum-based agents, such as cisplatin. Also provided are methods and kits involving the Pt-BASPs, or a pharmaceutical composition thereof, for treating proliferative diseases such as cancers (e.g., lung cancer, head-and-neck cancer, esophagus cancer, stomach cancer, breast cancer, pancreas cancer, liver cancer, kidney cancer, or prostate cancer) in a subject.

The invention discloses a self-balancing pressure-resistant casing device, and belongs to the technical field of a bathyscaphe pressure-resistant structure. The self-balancing pressure-resistant casing device is formed by sequentially sleeving and installing a ball-shaped inner casing, a ball-shaped middle casing and a ball-shaped outer casing around the ball center from inside to outside, wherein the ball-shaped inner casing and the ball-shaped middle casing are connected through a pair of symmetrical and coaxial connecting shaft assemblies; the ball-shaped middle casing and the ball-shaped outer casing are connected through a pair of symmetrical and coaxial connecting shaft assemblies; the axial lines of the two pairs of connecting shaft assemblies are mutually vertical, so that the ball-shaped inner casing and the ball-shaped middle casing can mutually rotate, and the ball-shaped middle casing and the ball-shaped outer casing can mutually rotate; each of the two pairs of connecting shafts is provided with a spring damper; the axial impact between the adjacent casings is resisted. The self-balancing pressure-resistant casing device has the advantages that a control system is simplified; the work reliability and the operation stability of a bathyscaphe are improved; the noise is a cabin is reduced; the work environment comfort of aquanauts is improved; the work safety of the bathyscaphe is improved; the material selective range is expanded; the thickness of the casings is reduced; the processing difficulty of the casings is reduced.
