Résumé
Since the outbreak of COVID-19 in Wuhan, cabin hospitals have played an important role in preventing the spread of the epidemic and admitting all the patients and suspected ones. As one of the first three cabin hospitals in Wuhan, Jianghan cabin hospital under care of Wuhan Union Hospital has efficiently fulfilled its purpose of admitting patients of mild symptoms. Measures taken by the cabin hospital include defining its positioning, optimizing its layout, establishing organization structure, setting up the rules and regulations, and strengthening the prevention and control of hospital infection. This article briefly summed up the operation and management practices of the cabin hospital, and analyzed its management difficulties, hence putting forward suggestions on medical emergency management system of China, for references of hospitals and authorities in charge.

As one of the first three cabin hospitals in Wuhan, Jianghan cabin hospital under care of Wuhan Union Hospital has efficiently fulfilled its purpose of admitting patients of mild symptoms. Measures taken by the cabin hospital include clearing its positioning, optimizing its layout, establishing organization structure, setting up the rules and regulations, and strengthening the prevention and control of hospital infection. This article briefly summed up the operation and management practices of the cabin hospital, and analyzed its management difficulties, hence putting forwards suggestions on medical emergency management system of China, for references of hospitals and authorities in charge.
Résumé
In order to study whether marrow stromal cells (MSCs) can be induced into nerve-like cells in vitro, and the mechanism, the MSCs in Wistar rats were isolated and cultured, and then induced with DMSO and BHA in vitro. The expression of specific marking proteins in neurons, glia and neural stem cells were detected before preinduction, at 24 h of preinduction, at 6 h, 24 h, and 48 h of neuronal induction by using immunohistochemistry and Western blotting. The ultrastructural changes after the inducement were observed. The results showed that after the inducement, many MSCs turned into bipolar, multipolar and taper, and then intersected as network structure. At the same time, some MSCs had the typical neuron-like ultrastructure. Immunohistochemistry revealed that NeuN and Nestin expression was detectable after inducement, but there was no GFAP and CNP expression. Western blotting showed the expression of Nestin was strong at 6 h of neuronal induction, and decreased at 24 h, 48 h of the induction. NeuN was detectable at 6 h of neuronal induction, and increased at 24 h, 48 h of the induction. It was concluded MSCs were induced into neural stem cells, and then differentiated into neuron-like cells in vitro.
