MAPK pathways regulated apoptosis and pyroptosis in respiratory epithelial cells of a primitive vertebrate model during bacterial infection.

Respiratory diseases caused by bacterial and viral infection have seriously affected human health. The invaginated lung structure in mammals caused difficulties in relevant research, here we evaluated the regulatory roles of MAPK pathways in apoptosis and pyroptosis during bacterial infection in an evaginated respiratory organ model for the first time.

[Status quo and influencing factors of disabilities caused by injury in Guangdong province].

Objective: To analyze the epidemiology status and risk factors of disabilities caused by injury in Guangdong province.

Methods: Stratified multi-stage cluster sampling was used to identify 1530 subjects with disabilities (among them, 415 disabilities caused by injury), in the villages or districts in the four regions of Guangzhou, Qingyuan, Zhaoqing and Huizhou in 2010.
