Objectives:Elevated circulating DNA(cirDNA)concentrations were found to be associated with trauma or tissue damage which suggests involvement of inflammation or cell death in post-operative cirDNA *** carried out the first prospective,multicenter study of the dynamics of cirDNA and neutrophil extracellular trap(NETs)markers during the perioperative period from 24 h before surgery up to 72 h after curative surgery in cancer ***:We examined the plasma levels of two NETs protein markers[myeloperoxidase(MPO)and neutrophil elastase(NE)],as well as levels of cirDNA of nuclear(cir-nDNA)and mitochondrial(cir-mtDNA)origin in 29 colon,prostate,and breast cancer patients and in 114 healthy individuals(HI).Results:The synergistic analytical information provided by these markers revealed that:(i)NETs formation contributes to post-surgery conditions;(i)post-surgery cir-nDNA levels were highly associated with NE and MPO in colon cancer[r=0.60(P<0.001)and r=0.53(P<0.01),respectivelyl,but not in prostate and breast cancer;(i)each tumor type shows a specific pattern of cir-nDNA and NETs marker dynamics,but overall the pre-and post-surgery median values of cir-nDNA,NE,and MPO were significantly higher in cancer patients than in ***:Taken as a whole,our work reveals the association of NETs formation with the elevated cir-nDNA release during a cancer patient's perioperative period,depending on surgical procedure or cancer *** contrast,cir-mtDNA is poorly associated with NETs formation in the studied perioperative period,which would appear to indicate a different mechanism of release or suggest mitochondrial dysfunction.

The geographical distribution of dominant plant species in China was georeferenced and climatic variables were interpolated into all ***,the percentage distributions of principal pollen taxa based on 1860 surface pollen sites in China were selected and the related climate values were interpolated with the same method. The geographical and climatic comparison between the two data-sets indicated that the climate threshold of most pollen taxa from surface pollen is coherent with plant distributions. The climatic envelopes of dominant plant are mostly accordant with those of pollen taxa at certain levels. However, some distinct offsets of the climate ranges exist between the two datasets for most pollen taxa identified at family level, such as Ericaceae,Asteraceae, Poaceae and Chenopodiaceae. The present study provides for the first time rich information on temperature and precipitation in relation to pollen and plant distribution based on the datasets on a continental scale useful for global ecological modeling and Quaternary palaeoclimate reconstruction.
