Abstract: This application is applicable to a multi-link group addressed traffic transmission method and an apparatus. A first access point (AP) of an AP multi-link device (MLD) sends group addressed traffic indication information indicating whether each AP of other APs of the AP MLD has a group addressed traffic, so that a station (STA) can learn whether the multiple APs have a group addressed traffic. In this way, each STA of the STA MLD does not need to listen to each AP whether each AP has a group addressed traffic. This reduces power consumption of the STA MLD. This application may be applied to a wireless local area network system that supports an IEEE 802.11ax next-generation Wi-Fi EHT protocol, for example, 802.11 series protocols such as 802.11be.

Abstract: This application provides a communications method and a communications apparatus. A first station in a first multi-link device sends first information to a second multi-link device, where the first information is used to indicate a frequency at which how often a station in a power saving mode in the first multi-link device receives a beacon frame. In this way, the second multi-link device may learn about, based on the first information, how often a frequency at which a station in the first multi-link device receives a beacon frame, thereby helping the second multi-link device effectively manage a cache service of each station in the first multi-link device and manage a data buffer space.

Abstract: The invention provides a 7-ethyl-10-hydroxycamptothecin drug precursor with fluorescence activity and a preparation method and use thereof. The method involves that a carboxyl group of a boron dipyrromethene dye molecule is condensed with a hydroxyl group at the 10 position of 7-ethyl-10-hydroxycamptothecin, yielding a 7-ethyl-10-hydroxy-camptothecin drug precursor (BDP-SN38) with fluorescent activity. BDP-SN38 shows good solubility and stability in most pharmaceutically acceptable solvents. Compared with SN38, BDP-SN38 exhibits comparable antitumor activity, has high tumor uptake capacity, and produces strong green fluorescence with the excitation of visible light, thus providing fluorescence-guided bioimaging and further treatment of residual tumors after drug treatment, and having good application prospects in the research of integrated diagnosis and treatment and effective tumor treatment.

Abstract: The present invention relates to the technical field of photosensitizers, and particularly to a near-infrared nano-photosensitizer and a preparation method and use thereof. The near-infrared nano-photosensitizer in the present invention is modified by conjugation extension of the boron dipyrromethene core, achieving absorption and emission spectra close to the near-infrared region. A polyfluoroalkyl group and a polyethylene glycol group are introduced to the boron dipyrromethene structure to obtain an amphiphilic photosensitizer. By means of the strong fluorine-fluorine interaction between the polyfluoroalkyl group and the hydrophilic interaction of the polyethylene glycol group, a nano-photosensitive micelle with an ultra-low CMC value is ultimately constructed. Boron dipyrromethene is induced by fluorine-fluorine interaction to undergo J-aggregation, causing the maximum absorption peak to red-shift to the near-infrared region, beneficial to the deep phototherapy of tumors.
