- rhythmic bacteria mainly belong to the Clostridium, Lactobacillus and Bacteroides It accounts for about 60% of the total number of intestinal bacteria.
- rhythmic changes of bacteria in the intestines of humans and mammals will expose the intestinal epithelial cells to different numbers and types of bacteria at different time periods, and these rhythmic changes of bacteria will pass on the intestinal epithelial cells. Metabolites reach remote tissues such as the liver, thereby causing rhythmic changes in gene expression in remote tissues such as the liver, which in turn causes rhythmic changes in lipid metabolism in humans and mammals, that is, the rhythm of lipid metabolism.
- the rhythm of lipid metabolism is very important to the health of humans and mammals. Once the rhythm of lipid metabolism is disordered, it will affect the absorption and storage of fat in food by humans and mammals, leading to a large amount of liver fat synthesis in humans and mammals, causing human and Rhythm disorder of serum triglycerides in mammals. Serum triglycerides are mainly synthesized by the liver, adipose tissue and small intestine, and their rhythmic disturbances can accelerate the occurrence of atherosclerosis, fatty liver, cerebral vascular blockage and insulin resistance in humans and mammals.
- High-energy diets such as high-fat diets and high-sugar diets will cause disorders in the composition of the human intestinal flora and the customized mucus layer of the flora, thus causing The human body’s gene expression is disordered, which in turn makes the body’s lipid metabolism rhythm disorder, and ultimately increases the body’s probability of suffering from diseases such as atherosclerosis, fatty liver, cerebral blood vessel blockage, and insulin resistance.

Three batches of mice were sacrificed at 2:00, 8:00, and 20:00, and the other group of mice was irrigated at 10:00 Gastric fluorescein FITC-dextran (FD4), intragastric dose of 0.6mg/g body weight, 4h after intragastric administration (14:00), sacrificed, peripheral blood was collected, and plasma was detected with fluorescent microplate reader (excitation light 485nm, emission light 535nm) FD4; After all animals were sacrificed, the serum triglycerides (TG), total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C) and high-density lipoprotein cholesterol (HDL-C) content and endotoxin (LPS) were measured ), endotoxin binding protein (LBP) and serum tumor necrosis factor alpha (TNF- ⁇ ) content, and use Acrophase software to perform cosine fitting of blood lipid circadian rhythm to analyze blood
- TG serum triglyceride
- TC total cholesterol
- LDL-C low-density lipoprotein cholesterol
- HDL-C high-density lipoprotein cholesterol
- LPS endotoxin
- LBP endotoxin binding protein
- TNF- ⁇ serum tumor necrosis factor alpha
- the changes in blood lipid circadian rhythm are analyzed by the following methods:
- RNA of clock genes Clock, Bmal1 and Per2 in mouse liver measure its purity (OD260/280) and concentration with NanoDrop, adjust the RNA concentration to about 1000ng/ ⁇ L, that is, OD 260/280 is in the range of 1.8 ⁇ 2.0
- the reverse transcription process is divided into two steps. In the first step, the system is mixed at 85°C, 5min, and quickly cooled on an ice bath. Then, after the second step is added to the system, the cDNA is obtained in a water bath at 37°C for 1h, 95°C, 3min. ; Use reverse-transcribed cDNA as a template for fluorescent quantitative PCR to obtain RNA, and the gene primer sequence is:
- the nucleotide sequence is shown in SEQ ID NO. 2 F: AGCACACACACTTCCTCTCTGACAT;
- the nucleotide sequence is shown in SEQ ID NO.3: R: ATCAAGGGACTGAACACTCAAGACC;
- the primer of the liver's biological clock gene Bmal1 (brain and muscle ARNT-like-1) (NCBI Gene ID: 11865):
- the nucleotide sequence is F shown in SEQ ID NO.4: AGTCAGATTGAAAAGAGGCGTCG;
- the nucleotide sequence is R shown in SEQ ID NO. 5: AGAAATGTTGGCTTGTAGTTTGCTT;
- the nucleotide sequence is shown in SEQ ID NO. 6 F: TTCTCTGCTGTTCTTGTATCCTTTT;
- the nucleotide sequence is shown in SEQ ID NO.7 R: GCTTTCTGCTGGGAGCTAATG;
- the amplification conditions of fluorescence quantitative PCR are: 95°C, 5min; 95°C, 20s, 62°C, 30s, 72°C, 20s; 72°C, 2min; ⁇ -actin is used as the internal reference, and the data is determined by the 2- ⁇ Ct method
- the weight of mice in the HFD group increased significantly compared with mice in the CON group (P ⁇ 0.01), an increase of about 14%; the weight gain of mice in the HFD+R group was significantly lower than that of mice in the HFD group, and a decrease of approximately 7%; as shown in Figure 2B, the weight growth rate of the HFD group mice increased significantly compared with the CON group mice, an increase of about 56%; the weight growth rate of the HFD+R group mice was significantly lower than that of the HFD group mice (P ⁇ 0.05), a decrease of about 21%. It can be seen that Lactobacillus reuteri FN041 treatment can significantly reduce the weight gain under the influence of high fat.
- the peritesticular adipose tissue index of mice in the HFD group was significantly increased compared to that of the CON group (P ⁇ 0.01), with an increase of about 100%; the peritesticular adipose tissue index of the HFD+R group was smaller than that of the HFD group Mice decreased significantly by about 30%. It can be seen that treatment with Lactobacillus reuteri FN041 can significantly reduce the abnormal increase in peritesticular adipose tissue index under the influence of high fat.
- the liver fat infiltration and testicular fat cell area of the HFD+R group mice were significantly lower than that of the HFD group mice (P ⁇ 0.05), with a decrease of about 10% and 28%, respectively. It can be seen that Lactobacillus reuteri (Lactobacillus reuteri) FN041 treatment can significantly reduce liver fat infiltration and abnormal increase in testicular fat cell area under the influence of high fat.
- the serum triglyceride content of mice in the HFD group was at 8:00 (P ⁇ 0.05), 14:00 (P ⁇ 0.01), and 20:00 (P ⁇ 0.05) compared with those in the CON group.
- the serum triglyceride content of HFD+R group mice was significantly lower than that of HFD group mice. It can be seen that Lactobacillus reuteri FN041 treatment can significantly reduce serum glycerol under the influence of high fat Triester (TG) content increased abnormally.
- TG high fat Triester
- the serum low-density lipoprotein cholesterol content of HFD group mice was significantly higher than that of CON group mice; the serum low-density lipoprotein cholesterol content of HFD+R group mice Compared with mice in the HFD group, there was a significant decrease, especially at 8:00 and 2:00 (P ⁇ 0.01). It can be seen that the treatment of Lactobacillus reuteri FN041 can significantly reduce the low density of serum under the influence of high fat. The content of lipoprotein cholesterol (LDL-C) is abnormally increased.
- the serum high-density lipoprotein cholesterol content of HFD group mice was significantly lower than that of CON group mice; the serum high-density lipoprotein cholesterol content of HFD+R group mice was significantly higher than that of HFD group mice, especially At 14:00 (P ⁇ 0.05), it can be seen that Lactobacillus reuteri FN041 treatment can significantly reduce the abnormal increase in serum high-density lipoprotein cholesterol (HDL-C) content under the influence of high fat.
- HDL-C serum high-density lipoprotein cholesterol
- the plasma FD4 content in the blood of the HFD group mice was significantly higher than that of the CON group mice; the plasma FD4 content in the blood of the HFD+R group mice was significantly lower than that of the HFD group mice, almost the same as the CON group mice Flat, it can be seen that Lactobacillus reuteri FN041 treatment can significantly improve the permeability of the mouse intestinal epithelial barrier, and inhibit the abnormal increase of plasma FD4 content in the blood of mice caused by high-fat diet feeding FD4 into the blood. .
- the serum tumor necrosis factor alpha (TNF- ⁇ ) content in the serum of the HFD group mice was significantly higher than that of the CON group mice; the serum tumor necrosis factor alpha (TNF- ⁇ ) in the serum of the HFD+R group mice The content of ⁇ ) was significantly lower than that of mice in the HFD group. It can be seen that treatment with Lactobacillus reuteri FN041 can significantly inhibit the abnormal increase in serum tumor necrosis factor ⁇ (TNF- ⁇ ) content under the influence of high fat.
