三黃茵赤湯抗氧化應(yīng)激抑制凋亡蛋白防治急性肝衰竭的作用
[Abstract]:objective
Acute liver failure (acute hepatic failure, AHF) is a serious damage to liver cells caused by a variety of factors, leading to serious disorders in the liver synthesis, metabolism, transport and excretion, and then the major manifestations of severe digestive system symptoms, extreme fatigue, deep jaundice, blood coagulation dysfunction, hepatic encephalopathy and ascites, etc. In the end, multiple organ failure and death.AHF will eventually appear fierce, rapid development, poor prognosis and a high mortality rate of 70%-80%. It is a serious harm to human health. Under the basic comprehensive treatment of Western medicine, traditional Chinese medicine is used to protect the remaining liver cells and promote the regeneration of the liver and improve the patients. The survival rate is particularly important. Because the symptoms of AHF are varied and the pathogenesis is complicated, it brings many difficulties to the clinical syndrome differentiation and treatment. However, we think that the acute liver failure is the stage of the liver disease, its main pathogenesis is "toxic stasis cementation, positive gas exhaustion", and the traditional Chinese medicine treatment should be mainly dispelling evil. AHF belongs to the category of "acute yellow", "bulge", "blood syndrome", "liver syncope" and so on. At present, the treatment of AHF is still lack of effective drugs. According to the long-term clinical experience of the key specialist in the combination of traditional Chinese and Western medicine in the Southern Hospital of Guangdong, we have made a study of Sanhuang Yin Chi decoction. This experiment was established by the establishment of D- amino galactose (D -GalN) combined with lipopolysaccharide (LPS) induced acute liver failure model in rats, the effects of three Huang Yin Chi Decoction on superoxide dismutase (Superoxide Dismutase, SOD), malondialdehyde (Malondialdehyde, MDA) and Caspase3 in the liver of AHF rats were observed to explore whether it could prevent acute liver failure by inhibiting apoptosis protein by anti oxidative stress. It provides a scientific theoretical basis for the treatment of AHF by Chinese medicine.
Method
1. experimental drugs
The composition of Sanhuang Decoction is rhubarb, Jiang Huang, astragalus, Artemisia capillaris, and Radix Paeoniae Rubra.
2. experimental animals and groups
48 SPF male SD rats weighing 200 to 220g were randomly divided into normal control group, model group, Sanhuang Yin Chi Tang high, middle, low dose group, bicyclic alcohol group, 8 rats in each group.
3. mold making
The rats were fed for 1 weeks under the condition of SPF, and after 1 weeks, the rats were given the stomach for 5 days in advance, then the model began to be made, and then the model was made. The fasting before the model was 12h, and the normal control group was injected with isotonic saline. The model group, the middle, low dose group, and the double ring alcohol group were injected with the abdominal injection of 10 mu g/kgLPS in the model group. After half an hour, the D-GalN. model of 700mg/kg was injected intraperitoneally. The post treatment group continued to gavage, providing a normal diet.48h after pentobarbital sodium 400mg/kg anesthetized rats, abdominal aorta blood collection, centrifugation, separation of serum and -80 C preservation, liver tissue, partially soaked in 4% polyformaldehyde, part of the -80 preservation.
4. observation and detection index
The content of alanine aminotransferase (ALT), aspartate aminotransferase (AST) and total bilirubin (TBIL) in the serum of each group was detected by an automatic biochemical analyzer, and the level of prothrombin time (PT), international standard ratio (INR) and plasma fibrinogen (FIB) were detected by automatic coagulant detector, and Nikon E was used. Oipse Ti-s inverted microscope was used to observe the pathological changes of liver in rats; the content of SOD and MDA in liver homogenate was detected by Superoxide Dismutase (SOD) detection kit and Malondialdehyde (MDA) detection kit, and the expression of Caspase3 in liver was detected by immunization. The relative expression level of Caspase3 in liver was detected by Western blot.
5. statistical method
The data were analyzed statistically with SPSS13.0 software, and the measured data were expressed with mean standard deviation (x + s). One-Way ANOVA variance analysis was used for the comparison of all the average numbers. If Tukey was used in the test of homogeneity of variance, Dunnett'T3 method was used, and the comparison of count data and rate was tested with the Tukey method. Statistical significance.
Result
1. results of liver function test
Compared with the model group, the high level of Sanhuang Yin Chi decoction, middle, low dose group and double ring alcohol group could reduce the content of ALT, AST and TBIL in the serum of rats, and there were significant differences (P0.01). The high dose group of Sanhuang Yin Chi decoction was equivalent to that of the double ring alcohol group (P0.05), and the low dose group was not as good as that of the double ring alcohol group (P0.05).
2. detection results of coagulation function
Compared with the model group, the high, middle, low dose group and double ring alcohol group could shorten the PT, INR time and increase the content of FIB in the rat serum, and there were significant differences (P0.01). The high dose group of Sanhuang Yin Chi decoction was equivalent to that of the double ring alcohol group (P0.05), and the low dose group was not like the double ring alcohol group, and there were also statistical differences (P0.05).
3. pathological morphological observation of the liver
The results of hematoxylin eosin staining (hematoxylin-eosinstaining, HE staining) showed that the structure of hepatic lobule in the normal control group was clear and the liver cells were arranged regularly. The liver cells in the model group were large, submajor necrosis, hepatic cord disorder, blurred structure of lobular lobule, hepatic sinusoid dilation and bleeding, intramedullary and confluence inflammation All the groups were improved, the swelling was reduced, and the necrosis was reduced. The high dose group was equivalent to the double ring alcohol group, and the lower dose group was not as good as the double ring alcohol group.
Detection results of SOD and MDA in 4. liver homogenate
The results showed that the high, middle, low dose group and double ring alcohol group could improve the activity of SOD in the homogenate fluid of the rat liver (P0.01) to reduce the content of MDA (P0.01), and the high dose group of Sanhuang Yin Chi decoction was equivalent to that of the double ring alcohol group (P0.05), and the low dose group was not as good as that of the double ring alcohol group, and there were also statistical differences (P0.05).
The results of 5. Caspase3 in situ expression
The results of immunohistochemical staining showed that Caspase3 was mainly expressed in the cytoplasm of liver cells, and the expression level of Caspase3 was reduced in the different dosage groups of Sanhuang Yin Chi Decoction (P0.05). The high dose group of Sanhuang Yin Chi decoction was equivalent to that of the double ring alcohol group (P0.05), and the low dose group was not as good as the double ring alcohol group, and there were also statistical differences (P0.05).
6. the effect of different doses of Sanhuang Yin Decoction on the expression of Caspase3 protein
Western blot analysis showed that the different dosage groups of Sanhuang Yin Chi decoction could reduce the expression level of Caspase3 (P0.01), and the high dose group of Sanhuang Yin Chi decoction was equivalent to that of the double ring alcohol group (P0.05), and the low dose group was not as good as that of the double ring alcohol group, and there were also statistical differences (P0.05).
conclusion
1. Sanhuang Yin decoction has the function of improving liver function and coagulation function.
2. Sanhuang Yin decoction can increase the activity of SOD in liver, reduce the content of MDA, reduce the expression of Caspase3, and inhibit the apoptosis of hepatocytes.
3. the effect of Sanhuang Yin Chi Decoction on prevention and treatment of acute liver failure, its possible mechanism is to inhibit the expression of Caspase3 through antioxidant stress and reduce the apoptosis of liver cells.
