Extracorporeal membrane oxygenation (ECMO), a kind of life support technology that can replace lung and heart function, is widely used in critical respiratory and circulatory exhaustion. Because of the serious diseases and the use of interventional catheters, patients receiving ECMO life support are often administrated with broad-spectrum antimicrobial agents, which increase the risk of fungal infection. Fungal infection during ECMO can increase mortality. How to effectively control fungal infection is a thorny problem faced by clinicians. During the treatment of ECMO, the patient's physiological status, ECMO oxygenation membrane, circulation pipeline and other factors may change the pharmacokinetic profiles of antifungal drugs, thereby affect the clinical efficacy of drugs. This artical reviews the pharmacokinetic characteristics of antifungal drugs during ECMO support, in order to provide references for clinical antifungal treatment.

As a crucial link in the progression of various chronic liver diseases to liver cirrhosis,liver fibrosis affects the prognosis and outcome of chronic liver diseases.Necrotosis is a novel pattern of programmed cell death(PCD),and studies have shown that it plays an important role in the pathophysiology of various diseases and is considered a potential target for improving liver fibrosis.Necroptosis of various types of intrahepatic cells(including hepatocytes,hepatic stellate cells,liver macrophages,and hepatic sinusoidal endothelial cells)can promote or inhibit liver fibrosis.This article elaborates on the above mechanisms and discusses the therapeutic strategies for targeting liver fibrosis mediated by necroptosis.

Chronic liver disease is the"devil's trilogy"in which the liver progresses from inflammation and fibrosis to liver cirrhosis and hepatocellular carcinoma,which poses a great challenge for hepatologists worldwide.Statins have played a significant role in the treatment of cardiovascular diseases and hyperlipidemia since their introduction,and in recent years,they have also demonstrated the potential to improve hepatic steatosis,exert an anti-inflammatory effect,regulate the phenotype of hepatic stellate cells,reduce portal venous pressure,and improve hepatic microcirculation in chronic liver disease.This article reviews the latest advances in the basic and clinical studies of statins in chronic liver disease,in order to provide new insights into the research,prevention,and treatment of chronic liver disease.

Dynamic changes in gut dysbiosis and metabolomic dysregulation are associated with immune-complex glomerulonephritis(ICGN).However,an in-depth study on this topic is currently lacking.Herein,we report an ICGN model to address this gap.ICGN was induced via the intravenous injection of cationized bovine serum albumin(c-BSA)into Sprague-Dawley(SD)rats for two weeks,after which mycophenolate mofetil(MMF)and losartan were administered orally.Two and six weeks after ICGN establishment,fecal samples were collected and 16S ribosomal DNA(rDNA)sequencing and untargeted metabolomic were conducted.Fecal microbiota transplantation(FMT)was conducted to determine whether gut normali-zation caused by MMF and losartan contributed to their renal protective effects.A gradual decline in microbial diversity and richness was accompanied by a loss of renal function.Approximately 18 genera were found to have significantly different relative abundances between the early and later stages,and Marvinbryantia and Allobaculum were markedly upregulated in both stages.Untargeted metabolomics indicated that the tryptophan metabolism was enhanced in ICGN,characterized by the overproduction of indole and kynurenic acid,while the serotonin pathway was reduced.Administration of losartan and MMF ameliorated microbial dysbiosis and reduced the accumulation of indoxyl conjugates in feces.FMT using feces from animals administered MMF and losartan improved gut dysbiosis by decreasing the Firmicutes/Bacteroidetes(F/B)ratio but did not improve renal function.These findings indicate that ICGN induces serous gut dysbiosis,wherein an altered tryptophan metabolism may contribute to its pro-gression.MMF and losartan significantly reversed the gut microbial and metabolomic dysbiosis,which partially contributed to their renoprotective effects.

Biapenem is a carbapenem antibiotic， and can be used for the treatment of sepsis， pneumonia， lung abscess， chronic respiratory lesions secondary infection， complex urinary tract infection and pyelonephritis， etc. This article reviewed the studies on the pharmacokinetics， pharmacodynamics and therapeutic drug monitoring （TDM） of biapenem. The pharmacokinetic parameters of biapenem are not significantly different in healthy subjects， and there is no accumulation after multiple doses of biapenem. However， there are large differences in pharmacokinetic parameters in patients with severe disease and patients with abnormal renal function compared with healthy subjects， which leads to conventional treatment regimens not achieving the desired outcome. In terms of pharmacodynamics， biapenem can improve the rate of reaching the target value by increasing the frequency of administration and prolonging the infusion time. For patients with anuria in end-stage renal disease， dosing intervals can be extended to avoid drug accumulation. However, for patients with severe infection, a daily dose of 1.2 g still can not control infections caused by Acinetobacter baumannii or Pseudomonas aeruginosa, which limits its use in patients with severe disease. It is recommended to implement TDM in severe patients and patients with abnormal renal function， and explore the best dosing regimen for biapenem in combination with pharmacokinetic models to ensure that the time that the free blood concentration of biapenem remains above minimum inhibitory concentration as a percentage of the time between doses （%fT＞MIC） is within the effective range，so that biapenem can exert a greater efficacy in severe patients and patients with abnormal renal function. For medical institutions that cannot carry out TDM， the efficacy of biapenem can be maximized by increasing the frequency of administration and prolonging the infusion time. For infections caused by P. aeruginosa， A. baumannii and Serratia marcescens with high drug resistance rates， it is recommended to combine or replace other antibiotics.
