OBJECTIVE To evaluate the mechanisms underlying the antidepressant effect of ZBH2012001,a novel serotonin and norepinephrine reuptake inhibitor(SNRI),in general and its ability to enhance monoaminergic transmission and suppress neuroinflammation in particular.METHODS① Male ICR mice were divided into vehicle(distilled water),duloxetine(DLX,10 or 20 mg·kg-1)and ZBH2012001(5,10 and 20 mg·kg-1)groups.One hour following ig administration,the antidepressant effect of ZBH2012001 was evaluated using the tail suspension test(TST)and forced swimming test(FST).② Radioligand binding assay was conducted to evaluate the affinity of ZBH2012001 for human serotonin transporters(hSERTs)and human norepinephrine transporters(hNETs).③ Mice were divided into vehicle(distilled water),DLX(10 or 20 mg·kg-1)and ZBH2012001(5,10 and 20 mg·kg-1)groups.One hour following drug administration,the 5-hydroxytryptophan(5-HTP)-induced head-twitch test or yohimbine-induced lethality test were performed to evaluate the effect of ZBH2012001 on the function of the 5-hydroxytryptamine(5-HT)and norepinephrine(NE)systems.④ Mice were divided into vehicle(distilled water+0.1%acetic acid),reserpine model(distilled water+reserpine 5 mg·kg-1),DLX(DLX 20 mg·kg-1+reserpine 5 mg·kg-1)and ZBH2012001(ZBH2012001 5,10 and 20 mg·kg-1+reserpine 5 mg·kg-1)groups.One hour following drug administration,reserpine was injected intraperitoneally to establish a monoamine-depletion model.The ptosis,akinesia,and hypothermia assays were performed to evaluate the effect of ZBH2012001 on the down-regulation of the reserpine-induced monoamine system.The TST in mice was used to evaluate the effect of ZBH2012001 on reserpine-induced depressive-like behavior while high-performance liquid chromatography with electrochemical detection(HPLC-ECD)was used to measure the levels of monoamines and their metabolites in the hippocampal tissue of reserpine-induced monoamine-depletion mice.ELISA was employed to detect the contents of tumor necrosis factor-alpha(TNF-α)and interleukin-6(IL-6)in the hippocampal tissue of reserpine-induced monoamine-depletion mice.Western blotting was used to assess the expressions of ionized calcium-binding adapter molecule-1(Iba-1)and nuclear factor-kappa B(NF-κB)in the hippocampal tissue of reserpine-induced monoamine-depletion mice.RESULTS ① Compared with the vehicle group,ZBH2012001(5,10 and 20 mg·kg-1)significantly reduced the immobility time both in the TST in mice(P<0.01,respectively),and ZBH2012001(20 mg·kg-1)and in the FST in mice(P<0.05).② ZBH2012001 competitively inhibited the binding of[3H]-imipramine to hSERTs and[3H]-nisoxetine to hNETs,with the half maximal inhibitory concentration(IC50)values of 84.95 and 712.90 nmol·L-1,respectively.③Com-pared with the vehicle group,ZBH2012001(10 and 20 mg·kg-1)significantly increased the head twitches induced by 5-HTP in mice(P<0.01,respectively)and increased the mortality rate in mice induced by yohimbine(P<0.05,P<0.01).④ In the reserpine-induced monoamine-depletion model in mice,compared with the vehicle group,mice in the reserpine model group exhibited ptosis,akinesia and hypothermia feature(P<0.01,respectively),significantly prolonged immobility time in the TST(P<0.01),significantly decreased the levels of NE,5-HT and dopamine(DA)(P<0.05,P<0.01),significantly increased the metabolic conversion rate of 5-HT and DA(P<0.01,respectively),significantly elevated levels of TNF-α and IL-6(P<0.05,respectively),and significantly increased expressions of Iba-1 and NF-κB(P<0.05,respectively)in the hippocampus.Compared with the model group,ZBH2012001(5,10 and 20 mg·kg-1)significantly antagonized ptosis and hypothermia behaviors induced by reserpine(P<0.01,respectively),ZBH2012001(10 and 20 mg·kg-1)significantly shortened the immobility time in reserpine-treated mice(P<0.05,P<0.01),ZBH2012001(20 mg·kg-1)significantly increased the levels of NE and 5-HT in the hippocampus of reserpine-treated mice(P<0.05,respectively),decreased the metabolic conversion rate of 5-HT(P<0.05),significantly reduced the contents of TNF-α and IL-6 in the hippocampus of reserpine-treated mice(P<0.05,respectively),ZBH2012001(5,10 and 20 mg·kg-1)significantly reduced the expression of Iba-1 protein in the hippocampus of reserpine-treated mice(P<0.01,respec-tively),and ZBH2012001(20 mg·kg-1)significantly reduced the expression of NF-κB protein in the hippocampus of reserpine-treated mice(P<0.05).CONCLUSION ZBH2012001 exerts its antidepres-sant effect through a dual mechanism involving monoamine enhancement and inflammation suppres-sion.

OBJECTIVE Based on the G protein-coupled bile acid receptor(TGR5)/nucleotide binding oligomerization domain-like receptor 3(NLRP3) signaling pathway, to explore the mechanism of Huoxue Qingjieling in improving the inflammatory response of rats with nonalcoholic steatohepatitis(NASH). METHODS A total of 70 male SD rats were randomly divided into 5 groups, 20 rats in the control group, 20 rats in the model group, 10 rats in each of the atorvastatin positive drug group, the high-dose and low-dose groups of Huoxue Qingjieling. The control group was given normal feed, and the rest of the groups were given high-fat diet. Through model evaluation, it was determined that the NASH rat model was successfully established at the end of the 20th week. After successful modeling, the control group and the model group were given with normal saline by intragastric administration, the atorvastatin positive drug group, and the high and low dose groups of Huoxue Qingjieling were given corresponding drugs once a day for 4 weeks. At the end of the 24th week, the rats were killed, and the changes of body weight, wet liver weight and liver index was calculated. The serum was taken to test the triglyceride(TG), total cholesterol(TC), alanine aminotransferase(ALT), and aspartic acid aminotransferase(AST) levels by automatic biochemical analyzer. Pathological changes of liver tissues were observed by HE staining and oil red O staining. The expression levels of TGR5 and NLRP3 proteins were detected by Western blotting and immunofluorescence staining. ELISA detected the content of interleukin-18(IL-18) and interleukin-1β(IL-1β) in liver tissue. RESULTS Huoxue Qingjieling could significantly improve the general state of NASH rats. Every dose group could significantly reduce the body weight, liver wet weight and liver index of rats(P<0.01), and TG, TC content and ALT, AST activity levels of serum significantly decreased(P<0.01). The pathological results showed that Huoxue Qingjieling could significantly improve liver steatosis, inflammation and balloon-like. The expression of TGR5 protein was significantly increased(P<0.01), the expression of NLRP3 protein and the content of IL-18, IL-1β were significantly decreased(P<0.01, P<0.05). CONCLUSION Huoxue Qingjieling can significantly improve the state of NASH rats, inhibit liver steatosis and inflammation, and its mechanism may be closely related to the inhibition of TGR5/NLRP3 signaling pathway.

Genome editing is a genetic manipulation technique that can modify DNA sequences at the genome level, including insertion, knockout, replacement and point mutation of specific DNA fragments. The ultimate principle of genome editing technology relying on engineered nucleases is to generate double-stranded DNA breaks at specific locations in genome and then repair them through non-homologous end joining or homologous recombination. With the intensive study of these nucleases, genome editing technology develops rapidly. The most used nucleases include meganucleases, zinc finger nucleases, transcription activator-like effector nucleases, and clustered regularly interspaced short palindromic repeats associated Cas proteins. Based on introducing the development and principles of above mentioned genome editing technologies, we review the research progress of CRISPR/Cas9 system in the application fields of identification of gene function, establishment of disease model, gene therapy, immunotherapy and its prospect.
