[Abstract]:Objective: To observe the effect of Jianpi Xiao Fu Fang on the content of triglyceride (TG), cholesterol (TC), high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C) and the expression of water channel protein 3 (AQP3) and water channel protein 4 (AQP4) in the colon tissue of hyperlipidemia rats, and to explore the therapeutic effect and possibility of the hyperlipidemia on hyperlipidemia. Methods: 60 healthy SD rats were selected and the body weight was 160g~180g, male, after adaptive feeding for one week, according to the principle of weight stratification, they were randomly divided into 6 groups: normal control group (normal group), model control group (abbreviated as model group), simvastatin control group (abbreviated as control group), low dose group of Jianpi eliminating phlegm prescription (abbreviated for short) The low dose group), the middle dose group of Jianpi eliminating phlegm prescription (medium dose group), the high dose group of Jianpi eliminating phlegm prescription (high dose group). The hyperlipidemia model was replicated by feeding high fat diet. Besides the normal diet, the other groups were fed with high fat diet. At the same time, the normal group and the model group were given proper amount of distilled water. Each group was given the treatment or control, and the dosage was calculated according to 1ml/100g. At the end of the fifth week, after the last administration, the rats were fasted for 24 hours. Under the anesthetic state, the femoral artery was taken blood, the blood samples were centrifuged, the serum was separated and the content of TG, TC, HDL-C, LDL-C in the serum was detected, and the liver was quickly dissected and the liver tissue of the largest lobe of the liver was dissected. In 4% of the 4% polycondensation Formaldehyde Solution, it was used for pathological observation. At the same time, the colon was dissected and 3 colonic tissues with relative fixed position were taken. After sciscent and rinse, 1 of them were put into 4% polycondensation of Formaldehyde Solution. The expression of AQP3 and AQP4 was observed by immunohistochemistry. The remaining 2 pieces were placed in the cryopreservation tube, and AQP3mR was used to observe AQP3mR by RT-PCR and Western Blot. The expression of NA, AQP4mRNA, AQP3 and AQP4. Results: 1 the content of TG, TC, HDL-C, LDL-C in serum of rats in each group was significantly higher than that in the normal group. The content of TC, TG, LDL-C in the serum of the model rats was significantly increased (P0.01), which suggested that the rat model was successful. Compared with the control group, the level of HDL-C in the high dose group had no obvious change (P0.05), and the content of TG, TC, LDL-C in the low dose group increased and the content of HDL-C decreased (P0.01 or P0.05) in the low dose group; the content of TG, TC, LDL-C in the high dose group was lower than in the high dose group, and the low dose group was higher than in the low dose group, and the low dose was higher than the low dose. Compared with low dose group (P0.01 or P0.05), the content of TC in middle dose group decreased (P0.05), but the content of TG, HDL-C, LDL-C had no significant difference (P0.05) the change of liver histomorphology in each group of rats (P0.05).2 group, the liver cells in the normal group were arranged orderly, the shape was regular hexagon, the central vein was radially distributed, and the structure of hepatic sinusoid was clear. In the model group, the liver cells in the model group were arranged in confusion and a large number of fat drops, the nucleus position was squeezed off and the hepatic sinusoid congestion and edema. The control group had clear liver cell structure, the fat drops obviously decreased, the hepatic sinusoid congestion and edema lightened, but there was cell necrosis and inflammatory cell infiltration. Invigorating the spleen and eliminating phlegm. In the middle and high dose group, the structure of the model group was clearer than the model group, the fat droplets were reduced in different degrees and the morphology of the hepatic sinusoids tended to be normal. The effect of the high dose group on the expression of AQP3 in the colon tissue of the.3 rats was significant. The expression of the positive cells in the normal group was less, the coloring was shallow, and the colon epithelium of the model group rats. The positive expression of the cell nucleus, cytoplasm and intestinal gland epithelial cells was relatively more, the coloring was deeper, and the connective tissue had a small number of positive expressions, suggesting that the expression of AQP3 in the colon tissue of the model group was significantly higher than that of the normal group (P0.01). The expression and coloring degree of the positive cells in the low dose group, middle dose group and high dose group decreased in turn; The expression of AQP3 in each group was lower than that of the model group (P0.01), and the expression of AQP3 in the high, middle and low dose groups was significantly lower than that of the control group (P0.01); in the three dose group, the AQP3 in the high dose group was significantly lower than the low dose group (P0.01); the expression of AQP3 in the middle dose group was lower than the low dose group (P0.05).Rt-pcr method: the colon tissue of the model group was AQP3. The expression of mRNA was significantly higher than that in the normal group (P0.01), and the expression of aqp3mrna in each drug group was lower than that in the model group (P0.01), and the expression of aqp3mrna in the middle dose group was lower than that of the control group (P0.01), while the low dose group had no difference compared with the control group (P0.05); in the three dose group, the high dose group aqp3mrna was lower than the low dose group (P0.01), The expression of aqp3mrna in the medium dose group was lower than the low dose group (P0.01).Westernblot method. The results of the study showed that the expression of AQP3 in the colon tissue of the model group was significantly higher than that of the normal group (P0.01). The expression of AQP3 in each drug group was lower than that of the model group (P0.01), and the expression of AQP3 in the middle dose group was significantly lower than that of the control group (P0.01), but the expression of the medium dose group was significantly lower than that of the control group (P0.01). There was no difference between the low dose group and the control group (P0.05); in the three dose group, the expression of AQP3 in the high dose group was significantly lower than that in the middle, low dose group (P0.01), and the expression of AQP3 in the middle dose group was lower than that in the colon tissue of the low dose group (P0.01).4. The expression of AQP4 in the colon tissues of the rats of each group was less than that in the normal group. In the model group, the nucleus of the colonic epithelial cells in the model group, the cytoplasm and the intestinal gland epithelial cells were more positive, the coloring was more deep, and the connective tissue had a small amount of positive expression. It suggested that the expression of AQP4 in the colon tissue of the model group was significantly higher than that of the normal group (P0.01).
