1 Objective:In the clinical part,Fibro Touch was used to evaluate the efficacy of Gan Dou Fu Mu Decoction(GDFMD)combined with Western medicine in the treatment of hepatolenticular degeneration(Wilson disease,WD)liver fibrosis.It is a non-invasive diagnosis and traditional Chinese medicine for WD liver fibrosis.Provide basis for intervention efficacy.Combined with animal experimental studies,observe the effects of GDFMD on the JNK signaling pathway and downstream factors of Toxic Milk(TX-J)by regulating the WD model,further clarify the molecular mechanism of GDFMD against liver fibrosis,and provide a theory for the clinical application of GDFMD Basic and scientific basis.2 Methods2.1 Clinical researchA total of 60 WD patients who were admitted to the outpatient and inpatient department of the Brain Disease Center of The First Affiliated Hospital of Anhui University of Traditional Chinese Medicine from September 2019 to September 2020 were selected.According to the principle of randomized control,they were divided into treatment group and control group,with 30 in each group.example.The patients were instructed to have a low-copper diet,the control group was treated with liver-protecting and copper-eliminating western medicine,and the treatment group was given oral administration of GDFMD based on the control group.The curative effects were evaluated 24 weeks after treatment,and the liver stiffness measurements(LSM),liver function(ALT,AST),liver fiber(HA,LN,PC-Ⅲ,C-IV),liver stiffness measurements(LSM),liver function(ALT,AST),and liver fiber(HA,LN,PC-Ⅲ,C-IV)were compared before and after treatment.TCM syndrome score,Uniform Wilson Disease Rating Scale(UWDRS)liver function score.2.2 Experimental researchAfter genetic identification,50 homozygous TX-J mice were selected,and 10wild-type TX-J mice were selected as the control group,all of which were 6 months old.Divided 50 TX-J mice were randomly divided into model group,penicillamine group and GDFMD high,medium and low dose groups,each with 10 mice.Different drugs and doses were given by gavage according to different groups.The control group and model group were given normal saline gavage for 4 weeks.2.2.1 Observe the effects of GDFMD on TX-J mice serology and liver histopathology:ELISA method was used to detect serum ALT,AST,HA,LN,MDA,SOD indicators;HE and Masson staining to observe histopathological changes of liver fibrosis;2.2.2 Observe the effect of GDFMD on the mitochondrial function of TX-J mice:A kit was used to detect the mitochondrial ROS content,ATP content and MMP changes in liver tissue.2.2.3 Observe the influence of GDFMD on the JNK pathway and downstream factors of TX-J mice:Western Blot was used to observe the protein expression of JNK,P-JNK,caspase-3,Bax and Bcl-2.3 Results3.1 Clinical part:3.1.1 Clinical curative effect: GDFMD combined with western medicine has better curative effect than western medicine alone.3.1.2
