EPO promotes axonal sprouting via upregulating GDF10.

Erythropoietin (EPO) has an exact neuroprotective effect on stroke. However, it remains unknown whether it participates in axonal sprouting after neuron damage. Growth and differentiation factor 10 (GDF10) has been shown to be a trigger of axonal sprouting after stroke.

[Analysis of pathogen isolated from lower respiratory tract in coalminer's pneumoconiosis patients complicated with infection].

Objective: To investigate the composition and resistance of main pathogens isolated form Lower respiratory tract in coalminer's pneumoconiosis patients complicated with infection to provide the basis for clinical treatment.

Method: Coalminer's pneumoconiosis patients complicated with infection during 2009 to 2010 were divided into mechanical ventilation group and non mechanical ventilation group. Specimens were obtained from lower respiratory tract by fibrobronchoscopy with protected specimen brush in patients of both groups to perform isolation, culture, identification and susceptibility test of pathogen.
