Abstract: Provided is a pharmaceutical formulation comprising 10-80 mg/ml of bevacizumab. The buffer system of the pharmaceutical formulation is preferably 10-30 mM histidine hydrochloride-sodium acetate buffer, in which 25-50 mg/mL of sucrose or sorbitol is used as a stabilizer, and Tween 80 is used as a surfactant, and the system has a pH of 5.0-5.6. The formulation is tested under repeated freezing and thawing and high-temperature acceleration conditions of 40° C. The protein stability is good, and is better than other similar formulations.

Abstract: Provided are an interactive method and system based on an augmented reality device, an electronic device, and a computer-readable medium. The method includes: obtaining current position information of the augmented reality device, and determining whether a loadable scene is included in a predetermined range of the current position (S11); obtaining a distance between the current position and the loadable scene to determine whether the augmented reality device enters a loading range of a target scene (S12); and loading a model of the target scene to display the target scene in the augmented reality device when the augmented reality device enters the loading range of the target scene (S13). The above method can achieve an accurate positioning and timely display of the target scene, thereby effectively improving the user experience.
