One 22-month-old boy who was admitted for a fever lasting 6 days as well as a cough and wheezing lasting 2 days was reported. He was diagnosed with influenza A （H1N1, severe type）, severe pneumonia, acute respiratory distress syndrome （ARDS）, Evans syndrome and multiple organ failure. This is the first case of novel influenza A （HIN1） and Evans syndrome. The pathogenesis is still unknown.

Amide, as a ubiquitous functional group, is essential in various aspects of chemistry and biology. Although the history of studying amide is rich and fruitful, the synthetic application of amide is very limited due to the inertness of amide C–N bond. Recently,significant advances have been achieved towards the nickel-mediated C–N activation of amides. This approach allows a facile generation of acyl-nickel intermediates, and a number of unique transformations have been designed and realized based on the amide C–N bond activation. Focused on the catalytic transformation, this review summarizes and categorizes the recent advances on the synthetic applications of Ni-mediated C–N bond activation of amides.
