To screen potential drugs for the treatment of acute Liver Injury(ALI)through network pharmacology and mitochondrial dynamics,and to investigate their actions and mechanisms.Based on the commonly utilized Liver Pure Tablets and Liver-Protecting Capsules in the market,a com-ponent library of liver disease drugs was screened and established.Pharmacological anchoring anal-ysis was carried out.Potential liver disease therapeutic drugs were screened out through molecular docking,and feedback verification was performed using animal experiments.Acute liver injury mouse models were established through excessive induction with acetaminophen(APAP),and the histopathological changes of liver tissues were examined.The protective effect of the drug on ALI was evaluated by detecting alanine aminotransferase(ALT),aspartate aminotransferase(AST),superoxide dismutase(SOD),catalase(CAT),glutathione(GSH),and malondialdehyde(MDA)using enzyme-linked immunosorbent assay(ELISA).qRT-PCR was employed to detect peroxi-some proliferator-activated receptor gamma coactivator 1-alpha(PPARG1A),mitofusin 1(MFN1),mitofusin 2(MFN2),dynamin-related protein 1(DRP1),optic atrophy 1 protein(OP A1),Steroid receptor coactivator(SRC),and advanced glycosylation end-product specific re-ceptor(AGER)to explore the protective mechanism of the drug on ALI.The result showed that Network pharmacology identified a total of 662 intersection targets of three types of prescription drugs and ALI.Eventually,72 core targets were screened out.Pathway enrichment analysis indi-cates that the potential mechanism might be associated with the lipid and atherosclerosis signaling pathways.The results of the relevant molecular docking indicate that the most likely optimal drug might be emodin(EMO).EMO ameliorated the pathological damage in mice with acute liver inju-ry,significantly decreased the contents of transferase factors ALT and AST,simultaneously in-creased the contents of antioxidant enzymes CAT,GSH and SOD,and reduced the content of oxi-dative metabolic end product MDA.It also upregulated the mRNA expression levels of MFN1、MFN2,OPA1,DRP1,SRC and PPARGC1A proteins in liver tissue,and inhibited the mRNA ex-pression level of AGER protein.The drug EMO,jointly screened out by network pharmacology through anchoring and molecular docking,might promote mitochondrial fusion metabolism,allevi-ate liver oxidative stress,and improve liver injury in ALI mice via the Lipid and atherosclerosis pathway.

ObjectiveTo observe the dose of methadone and the compliance of patients to the methadone maintenance treatment(MMT).MethodsWe analyzed the status of 69 patients who were addicted to opiate medication and 44 patients who dropped out in our clinic until July 31,2010.ResultsThere was no significant relationship between patients' urine test and the dose.Crime caused the patients who dropped out.The percentage of positive urine did not decline as the dose increased,but the rate of patients who dropped and the number of positive urine test showed a significant correlation( r =0.523 P =0.000).Crime was the main reason that affected the compliance to MMT and caused dropping out.ConclusionThe use of MMT dose should be individualized.

Objective To explore the effect of psychotherapy in patients with methadone maintenance treatment.Methods 60 patients accepted drug and 69 patients accepted drug with psychotherapy treatment were evaluated with Self-Rating Anxiety Scale(SAS) and Self-rating Depression Scale(SDS) in the beginning of psychotherapy therapy and 3 months later.All of them were assessed for heroin use at 3 months after the end of a 3-month treatment period.Results SAS、SDS did not show any significant differences between the two groups in the beginning(P >0.05).After 3 months of psychotherapy,the differences in SDS and SAS between the two groups showed statistically significant(t =- 2.858,- 2.465,all P <0.05).After 2 months of psychotherapy,the number of relapsing again patients of group psychotherapy treatment was significantly lower than control group(x2 =6.906,5.054,5.100,4.247,all P <0.05).Conclusion The mental healthy status of patients with heroin dependence is poor.Psychological treatment plays an important role in short-term prevent hernoin addicts from relapse again.
