ABSTRACT
OBJECTIVE To investigate the underlyingmechanism on the association of red blood cell and gut microbiota in rats induced by High-Fat Diet(HFD).METHODS A total of 36 male Sprague-Dawley rats (180±20g) were randomly divided into two groups. The control group (n=10) was given a normal chow diet(10% calories of fat),and the High-fat diet group(n=26)was given a HFD(60% calo-ries of fat).We recorded body weight,length and detected serum glucose,serum lipids and insulin ev-ery two weeks.The fresh arterial blood was collected during the experiments and blood gases were measured immediately (Radiometer Medical ApS, Denmark).Thehematocrit (Hct) and partial pressure of oxygen(pO2)were detected by the sensor cassette,following themanufacturer′s instructions.The de-tection method was conductivity measurements and current method, respectively. The feces from ce-cum were analyzed by 16S rRNA gene high-throughput sequencing(Illumina Miseq,USA). RESULTS According to the insulin resistance(IR),body weight and body length,the model group was divided into two small groups.(1)IR group,in which IR,body weight and body length were higher than the control group (P<0.05). (2) un-IR group, body weight and body length were higher than the control group (P<0.05),but the IR was not significantly different.In addition,the levels of hematocrit(Hct),checktotalhe-moglobin (ctHb) and check total blood oxygen content (ctO2) showed significantly increased in the IR group when compared with the control group (P<0.05), however, the pO2was not statistically signifi-cant. Furthermore, we identified that the genus Lactobacillus was moderate positive correlation with Hct,ctHb and ctO2(P<0.05).Compared with the control group,the relative abundance of the Lactoba-cillus was significantly lower in IR group(P<0.05).CONCLUSION The high-fat diet induced rats′local tissue hypoxia under the red blood cell increasing,oxygen partial pressure constant and the reduction of Lactobacillus′abundance might be caused by aerobic oxidation and glycolysis inhibition in the meantime.
