求翻译：模拟冬季组褪黑素含量、AANAT酶活性及蛋白质水平高于模拟夏季组，且有显著性差异（p＜0.05），与自然条件下冬夏节律一致是什么意思？

Melatonin content of the simulated winter group, aanat activity and protein levels higher than the simulation of the summer group, and there is significant difference (p <0.05), consistent with natural conditions winter and summer rhythm

Analog winter group Black quality and content, AANAT enzyme activity and protein levels were higher than analog summer Group, and there is a significant difference (p<0.05 ) under natural conditions, with a winter and summer rhythm

The simulation winter group sheds the black element content, the AANAT enzyme activity and the protein level is higher than the simulation summer the group, also has the significance difference (p<0.05), the winter summer rhythm is consistent with the natural condition under

Simulation group of melatonin in winter, AANAT enzyme activity and protein content higher than group simulation in summer, and there are significant differences (p<0.05), consistent with the rhythm of nature in winter and summer
