Abstract: Disclosed are a device of complex gas mixture detection based on optical-path-adjustable spectrum detection and a method therefor, and the device includes: a light source configured for generating an incident beam and emitting the incident beam into an optical gas cell; the optical gas cell, including a cavity configured for accommodating a gas sample, and a reflection module group configured for reflecting the incident beam and a track arranged in the cavity, where the track is consistent with a light path of the light beam in the cavity; a detector module that is connected with the track in a relatively movable manner and is configured for receiving light beams and obtaining spectral data, where an optical path is changed by moving the detector module relative to the track; and a data acquisition unit that is configured for acquiring the spectral data obtained by the detector module.

Abstract: Disclosed is the use of a KOR agonist in combination with a MOR agonist in preparing a drug for treating pain. The KOR agonist is selected from a compound as shown in the general formula (I), and the MOR agonist is selected from a compound as shown in the general formula (II), wherein the definitions of each substituent in the general formula (I) and (II) are the same as defined in the description.

Abstract: The present disclosure provides the use of an anti-PD-1 antibody in combination with famitinib in the preparation of a drug for treating tumors. In the present technical solution, toxicity is controllable and tolerable. At the same time, the described drug combination effectively reduces adverse reactions to the anti-PD-1 antibody, such as the occurrence of reactive capillary endothelial proliferation.
