Regional whole-course trauma care - Experiences from a county-level hospital.

Fifty percent of the deaths caused by severe trauma occur within 1 h after injury. With the concepts of "golden 1 h" and "platinum 10 min", the professionals in the field of emergency trauma treatment have agreed on the necessity of establishing a rapid and efficient trauma rescue system. However, due to the size of the hospital, the population in the neighborhood, the local economic conditions and geographical features, how to establish an optimal trauma rescue system remains an issue.

Activation of muscarinic receptors protects against retinal neurons damage and optic nerve degeneration in vitro and in vivo models.

Aims: Muscarinic acetylcholine receptor agonist pilocarpine reduces intraocular pressure (IOP) of glaucoma mainly by stimulating ciliary muscle contraction and then increasing aqueous outflow. It is of our great interest to know whether pilocarpine has the additional properties of retinal neuroprotection independent of IOP lowering in vitro and in vivo models.

Methods: In rat primary retinal cultures, cell viability was measured using an MTT assay and the trypan blue exclusion method, respectively.
