Metabolic associated fatty liver disease （MAFLD） has become one of the most prevalent chronic liver diseases worldwide， with the core pathological feature of pathological accumulation of triglycerides in hepatocytes， and as a key rate-limiting enzyme for triglyceride synthesis in the liver， 2-acylglycerol O-acyltransferase 2 （DGAT2） plays a central role in this process. Cell and animal model studies have confirmed that inhibition of DGAT2 can effectively alleviate hepatic steatosis and delay disease progression， and subsequent clinical trials have also shown the potential clinical application value in the treatment of MAFLD. This article systematically reviews the mechanism of action of DGAT2 in the development and progression of MAFLD and comprehensively summarizes the therapeutic strategies targeting DGAT2， including the advances in both monotherapy and drug combinations， in order to provide new ideas for individualized treatment of MAFLD patients.

Aim To explore the role of zinc transporter 6(SLC30A6)on the proliferation,migration and inva-sion capabilities of hepatocellular carcinoma(HCC)cell line Huh7,and to identify potential traditional Chi-nese medicine(TCM)small-molecule inhibitors targe-ting SLC30A6 from the China Natural Products Data-base(CNPD)using virtual screening techniques.Methods The expression levels,clinical characteris-ticsand prognostic value of SLC30A6 in HCC were pre-dicted based on TCGA and ICGC datasets.SLC30A6 was knocked down in Huh7 cells using lentiviral trans-fection.The effects on cell proliferation,migration,and invasion were assessed using CCK-8,EdU,wound heal-ing,and Transwell assays.The regulation of HCC cancer stem cell markers(CD44,CD133,CD90)by SLC30A6 was also examined.Based on the CNPD,a docking-based virtual screening strategy was employed,including high-throughput virtual screening,standard precision virtual screening,and high-precision virtual screening,to identify the potential drug candidates with high specificity and favorable drug-likeness.Results SLC30A6 expression was upregulated in HCC tissues.Higher SLC30A6 levels were associated with advanced pathological stages,histological grades,alpha-fetopro-tein(AFP)levels,vascular invasion,and poor progno-sis in HCC patients.SLC30A6 knockdown significantly inhibited the proliferation,migration,and invasion of Huh7 cells and reduced the levels of HCC cancer stem cell markers.Virtual screening identified six potential TCM small-molecule inhibitors.Conclusions SLC30A6 can regulate the proliferation,migrationand invasion of HCC cells.SLC30A6 may serve as a poten-tial prognostic biomarker and therapeutic target for HCC.

Objective To investigate the clinical efficacy and safety of facilitated percutaneous coronary intervention(PCI)with half-dose recombinant staphylokinase(r-SAK)in patients with ST-segment elevation myocardial infarction(STEMI)who are expected to undergo PCI within 120 minutes.Methods From October 2021 to August 2022,a total of 200 STEMI patients in eight centers were included and randomly assigned in a 1﹕1 ratio to either r-SAK group or control group.Patients received loading doses of aspirin and ticagrelor and intravenous heparin and were randomized to receive an intravenous bolus of either 5 mg r-SAK or normal saline prior to PCI.The outcomes were set as ST-segment resolution(STR)at 60-90 minutes after PCI,the proportion and transition of pathological Q waves on the 5th day after PCI,and the proportion of high-sensitivity cardiac troponin T(hs-cTnT)peaking within 12 hours of onset.The safety outcome was major bleeding events defined as Bleeding Academic Research Consortium(BARC)≥type 3 bleeding during hospitalization.Results Compared with the control group,the r-SAK group had a higher proportion of STR≥70%within 60-90 minutes after PCI(58.3%vs.40.3%,P=0.009);a lower proportion of pathological Q waves(59.1%vs.74.1%,P=0.040);a lower rate of Q wave progression(14.8%vs.43.2%,P＜0.001);a higher rate of Q wave disappearance(12.5%vs.3.7%,P=0.027);and a higher proportion of hs-cTnT peaking within 12 hours of symptom onset[31/40(77.5%)vs.17/33(51.5%),P=0.027].Regarding the safety outcome,no significant difference in BARC≥type 3 bleeding was found between the two groups during hospitalization(P＞0.05).Conclusions For STEMI patients who were expected to undergo primary PCI within 120 minutes of symptom onset,the facilitated PCI with half-dose r-SAK significantly increased the proportion of STR≥70%at 60-90 minutes after PCI,reduced the formation of pathological Q waves,and shortened the time to peak hs-cTnT,without increasing the risk of bleeding,which should be an alternative reperfusion strategy worthy of further study.

This study aimed to explore the therapeutic mechanisms of Colquhounia Root Tablets(CRT) in treating diabetic kidney disease(DKD) by integrating biomolecular network mining with animal model verification. By analyzing clinical transcriptomics data, an interaction network was constructed between candidate targets of CRT and DKD-related genes. Based on the topological eigenvalues of network nodes, 101 core network targets of CRT against DKD were identified. These targets were found to be closely related to multiple pathways associated with type 2 diabetes, immune response, and metabolic reprogramming. Given that immune-inflammatory imbalance driven by metabolic reprogramming is one of the key pathogenic mechanisms of DKD, and that many core network targets of CRT are involved in this pathological process, receptor for advanced glycation end products(RAGE)-reactive oxygen species(ROS)-phosphatidylinositol 3-kinase(PI3K)-protein kinase B(AKT)-nuclear factor-κB(NF-κB)-NOD-like receptor family pyrin domain containing 3(NLRP3) signaling axis was selected as a candidate target for in-depth research. Further, a rat model of DKD induced by a high-sugar, high-fat diet and streptozotocin was established to evaluate the pharmacological effects of CRT and verify the expression of related targets. The experimental results showed that CRT could effectively correct metabolic disturbances in DKD, restore immune-inflammatory balance, and improve renal function and its pathological changes by inhibiting the activation of the RAGE-ROS-PI3K-AKT-NF-κB-NLRP3 signaling axis. In conclusion, this study reveals that CRT alleviates the progression of DKD through dual regulation of metabolic reprogramming and immune-inflammatory responses, providing strong experimental evidence for its clinical application in DKD.
