Abstract: An absorbable copolymer, and a preparation method and use thereof are disclosed. Firstly lactide and trimethylene carbonate are polymerized to form a prepolymer, and then the prepolymer is copolymerized with glycolide to form a PGLT copolymer. The PGLT copolymer contains three chain segments of polymerized glycolide, polymerized lactide and polymerized trimethylene carbonate. The PGLT copolymer obtained by stepwise polymerization has high strength and good toughness. It is suitable for the preparation of medical instruments such as absorbable tissue closure clips, suture clips, suture anchors, anastomosis nails, etc.

Abstract: Provided in the present invention are a biodegradable ureteral stent and a preparation method therefor. The biodegradable ureteral stent is of a hollow circular tubular structure (1), a fixing structure (2) for preventing sliding is disposed at two ends or one end, a tube wall is also provided with a plurality of penetrating drainage side holes (3), and a material used is a composite material formed by at least a glycolide-?-caprolactone copolymer, an ethylene oxide polymer, and a medical developer. In the glycolide-?-caprolactone copolymer, a weight percentage content of glycolide is 51-58%, such that the copolymer has appropriate mechanical strength and softness and hardness and gradually becomes soft with prolonging of the degradation time. Meanwhile, a certain proportion of the ethylene oxide polymer is added, such that the polymer has a lower constant stretch modulus after degradation and is softer and smoother.

Abstract: In an embodiment, a processor receives anchor text configuration data for a web page, and determines whether the anchor text configuration data includes a preference to use at least a portion of a web page title as a string of anchor text that refers to that web page. If the anchor text configuration data includes the preference, then the processor determines whether software code underlying the web page includes at least one of: <h1>, <title>, and og:title. If the determination is positive, then a link is configured to display the string of anchor text on a different web page, the link being represented at least in part by the at least one of <h1>, <title>, and og:title. The link is further configured to, when included in the first web page, create a modified web page and send the configured link to the different web page.

Abstract: In an embodiment, a processor receives a request for a first web page within a website. In response, the processor sends over a computer network a request for a web-page modification to the first web page. The processor receives the requested web-page modification, which includes a link associated with a second web page within the website, and configured to be installed in the first web page. The processor then modifies the first web page to incorporate the web-page modification, and the modified web page is then served to the requestor.
