Abstract: A method for treating a subject suffering from refractory rheumatoid arthritis includes the step of administering an effective amount of a quinonemethide triterpenoid or a pharmaceutically tolerable salt, solvate or anhydrate thereof to the subject. Also is a method for inducing autophagy in a synovial fibroblast, and a method of inducing calcium mobilization in a synovial fibroblast. Further a pharmaceutical composition includes an effective dose of a quinonemethide triterpenoid and an anti-arthritis compound. The quinonemethide triterpenoid is suitable to treat refractory rheumatoid arthritis (RA) in particular ABC-protein-dependent RA and apoptosis-deficient RA. The quinonemethide triterpenoid also possesses significant inhibitory effects on the growth of synovial fibroblasts, in particular modulating the calcium homeostasis in multidrug-resistant rheumatoid arthritis synovial fibroblasts.

Abstract: A battery cover mechanism for a portable electronic device includes a housing, a door, two elastic members and a holding unit, the housing defines a cutout, the door slidably engage with the cutout, the cutout is closed by the door with the elastic resisting the door, the door can be opened by external force and not be removed from the housing, thus, a battery can be assembled in the housing.

Abstract: A battery cover mechanism for a portable electronic device includes a housing, a door, two first elastic members and a holding unit, the housing defines a cutout, the door slidably engage with the cutout, the cutout is closed by the door with the elastic resisting the door, the door can be opened by external force and not be removed from the housing, thus, a battery can be assembled in the housing.

Abstract: A card socket assembly includes a base defining a receiving cavity, and a slider including a card slot configured for securing a data card therein. The slider is slidably received in the receiving cavity, to make the data card secured in the receiving cavity or removed out of the receiving cavity with sliding of the slider.
