Association between pneumonia in acute stroke stage and 3-year mortality in patients with acute first-ever ischemic stroke.

The influence of pneumonia in acute stroke stage on the clinical presentation and long-term outcomes of patients with acute ischemic stroke is still controversial. We investigate the influence of pneumonia in acute stroke stage on the 3-year outcomes of patients with acute first-ever ischemic stroke. Nine-hundred and thirty-four patients with acute first-ever ischemic stroke were enrolled and had been followed for 3years.

[The application of trace element analysis to the study of provenance of copper minerals in ancient bronzes].

The simulated smelting and founding experiment of bronze showed that the copper minerals from different regions could be distinguished clearly by using the multi-statistical analysis based on choosing the chalcophile elements determined by ICP-AES. In the present paper, the data of trace elements in bronzes from Panlongcheng Site and Ezhou, which were determined by NAA, were tried to be processed. The analytical result showed that the bronzes from Panlongcheng and Ezhou could be divided clearly, just like the results of the former simulated smelting and founding experiment of bronze.
