Abstract: Disclosed is a method for preparing an environmentally-friendly high-strength wood composite material, which includes the following steps: S1. pulverizing wood into a wood flour, adding the wood flour to an acid solution to obtain a first mixture, ball milling the first mixture to obtain a ball milled mixture, and filtering the ball milled mixture, to obtain a dually-treated wood flour; S2. adding the dually-treated wood flour to a first alkaline solution, and performing a neutralization reaction, to obtain a second mixture; S3. adding an alkaline solution to the second mixture to remove part of lignin, to obtain a lignin-partially removed wood flour; S4. washing the lignin-partially removed wood flour with anhydrous ethanol and drying, to obtain a dried lignin-partially removed wood flour; S5. subjecting the dried lignin-partially removed wood flour to hot pressing, followed by cooling, to obtain the environmentally-friendly high-strength wood composite material.

Abstract: Disclosed are a diglycosylated benzophenoxazine photosensitizer, and a preparation method and use thereof. The present invention greatly improves the enriched concentration of the photosensitizer in tumor cells by taking full advantage of the enhanced uptake and enhanced glycolysis of carbohydrates by tumor cells and the glycosylation of a selenium-containing benzophenoxazine compound, thereby improving the targeting of a diglycosylated benzophenoxazine photosensitizer involved in the present invention in the treatment of cutaneous tumors and also significantly decreasing the toxic and side effects of the photodynamic therapy. The present invention can efficiently and rapidly inhibit the proliferation of cells of cutaneous squamous cell carcinoma and essentially cause no damage to normal cells.
