The application discloses a reef limestone underground chamber damping system and belongs to the field of damping devices. The reef limestone underground chamber damping system comprises an elastic bearing assembly, micro-grouting hole pipelines, composite variable resistors and pressure sensors. The elastic bearing assembly comprises basalt micro-tendon and stainless steel energy dissipation nodes. A plurality of basalt micro-tendons form a constraint network along the circumference and axis of the chamber on the inner wall of the chamber. The stainless steel energy dissipation nodes are arranged at the intersection connection between the basalt micro-tendons. A plurality of micro-grouting hole pipelines are arranged in the constraint network along the axis of the chamber. The pressure sensors are embedded in the rock above the chamber. A plurality of composite variable resistors are arranged at the arch foot of the chamber. The three-stage collaborative mechanism of "basalt micro-tendon constraint-SMA-MRF collaborative energy dissipation-SMA heating phase change recovery and micro-grouting" solves the adaptability bottleneck of traditional anti-seismic technology in reef limestone underground space, and improves the anti-seismic performance and long-term service reliability.

The invention discloses application of angelica lactone in preparation of a medicine for treating atopic dermatitis, and belongs to the technical field of medicines. According to the application, BALB / c mice are used as an atopic dermatitis model, experiments are carried out by evaluating skin lesion scores of the mice before and after medication and applying various technical means such as histopathology and western blot, and results show that angelica lactone has an effective treatment effect on the atopic dermatitis. Angellactone can alleviate the expression of related inflammatory factors by inhibiting MAPKs / NF-kappa B signal pathways, and promote the expression recovery of skin barrier key proteins FLG and LOR in a dose-dependent manner, thereby repairing the skin barrier function. According to the present invention, the medical application of the angelica lactone is expanded, and the new direction is provided for the treatment of atopic dermatitis, such that the angelica lactone is provided as the potential drug for AD treatment or skin barrier repair.

This invention discloses a method and apparatus for repairing damage to the mounting surface of an axle housing. The method includes the following steps: obtaining dimensional measurements of corrosion pits at the damaged location on the mounting surface of the axle housing to determine the defect area, and removing the corrosion layer from the defect area using subtractive machining; classifying the defect areas and, based on the type of each defect area, spraying corresponding coatings to obtain corresponding repair areas; and performing subtractive remanufacturing on each repair area to restore the dimensions of the mounting surface. This method not only removes corrosion products from the mounting surface of the axle housing but also, based on machining to remove corrosion, efficiently and accurately restores the dimensions of the axle housing through a process of additive and subtractive machining. It eliminates the impact of traditional thermal repair methods on the part's microstructure, dimensional accuracy, and mechanical properties, further improving the service life of the axle housing.
