Objective To evaluate the diagnostic accuracy of drug-induced liver injury over a 10-year period . Methods The 112 cases of drug-induced liver injury were retrospectively studied. Inter-national consensus criteria were applied to assess the causality of suspected drug hepatotoxicity,in which the chronological criteria and elimination of other causes were analysed. Results Among 1127 adult inpatients with acute hepatitis over 10-year period, 112 patients(10%) were recorded as drug-induced liver injury. Based on the causality assessment of 112 cases, either incompatible time to apparent onset of the reaction or incompatible course of the reaction was found in 60 cases(53.6%) and 20 cases(17.9%), respectively. The presence of other possible causes for the reaction was found in 34 patients (37.5%). Therefore, 26 cases(23.2%) of liver injury were related to the incriminated drug, 25 cases(22.3%) unrelated,61(54.5%) were considered to indeterminate cause. Conclusions The international consensus criteria were helpful to identify drug-related or unrelated liver injury, but more than half of reported hepatic adverse drug reactions are still in suspected condition. The current diagnostic methods for drug-induced liver injury are needed to be revised in clinical practice.

Objective:To analyze the clinical features of patients with pyogenic liver abscess (PLA) and the application of mNGS in PLA, thus to provide reference for clinical diagnosis and treatment.Methods:The demographic and clinical data of 549 patients with liver abscess admitted to Zhongshan Hospital Affiliated to Fudan University from December 2015 to June 2020 were analyzed retrospectively. According to the detection of Klebsiella pneumoniae in 246 patients with positive etiological test results, the patients were divided into two groups: KPLA group and nKPLA group, and clinical characteristics of the two groups were compared. At the same time, the application value of mNGS in PLA was analyzed.Results:Among the 549 patients, the main clinical symptom of PLA was fever ( n= 503, 91.6%) and other clinical symptoms included chills and abdominal pain. Most patients had a single abscess ( n= 464, 84.5%) located in the right lobe ( n = 368, 67.0%), with a size between 5 and 10 cm ( n= 341, 62.1%). A total of 246 patients had positive etiological test results, including 202 KPLA patients which was the main pathogen of liver abscess. The prevalence of diabetes and fatty liver was higher in KPLA patients ( P < 0.05), but there were more culture of liver positive factors in nKPLA patients ( P < 0.001). Among the 109 patients with traditional microbiological results, 92 patients were suspected to KPLA (Klebsiella pneumoniae), of which 14 patients (15.2%) were multidrug resistant (MDR) infection; 17 patients were suspected to nKPLA, of which 10 patients (58.8%) were MDR infection; the incidence of MDR infection in patients with nKPLA was significantly higher than that in patients with KPLA ( P < 0.05). The positive rate of mNGS in plasma was 85.2%, the positive rate of traditional microbial culture in plasma was 14.8%, the positive rate of mNGS in pus was 96.2% and traditional microbial culture in pus was 65.4%. The positive rate of traditional culture was significantly lower than that of mNGS ( P < 0.05). Conclusions:PLA is usually manifested as fever, single and at the right lobe of the liver. Klebsiella pneumoniae is the most common pathogenic bacteria of PLA, which is more common in patients with diabetes and fatty liver, while non-Klebsiella pneumoniae is relatively more common in patients with culture of liver positive factors. The positive detection rate of mNGS is high, which has a unique advantage in pathogen detection.

Objective:To investigate the mechanism of activation of NOD-like receptors protein (NLRP)3 in the process of human adenovirus type 7 (HAdV-7) infection.Methods:THP-1 cells were treated with adenosine triphosphate (ATP), an NLRP3 inhibitor MCC950, and a caspase-1 inhibitor Ac-YVDK-cmk, ammonium pyrrolidinedithiocarbamate (APDC), N-acetyl-L-cysteine (NAC), cathepsin B-selective inhibitor CA-074-me, glibenclamide and potassium chloride (KCl) respectively. THP-1 cells without infection were used as the control group and those infected with HAdV-7 were used as the experimental group. The expression of NLRP3, caspase-1 and IL-1β in the supernatant was detected by enzyme-linked immunosorbent assay (ELISA), Q-PCR and western blot(WB).Results:Immunofluorescence detection showed that HAdV-7 infected THP-1, while WB showed that HAdV-7 infection could induce the pro-IL-1β protein expression in cells, and caspase-1 cleavage induce IL-1β maturation and release to the outside of cells. The expression of IL-1β in the supernatant of cells was significantly increased as detected by ELISA (MOI=0.5, P=0.0008). After inhibition of caspase-1 expression, the expression of IL-1 β in the supernatant was significantly inhibited ( P=0.0025). The expression of pro-IL-1β and NLRP3 mRNA in HAdV-7 infected cells was up-regulated (NLRP3: P=0.0004; pro-IL-1β: P=0.0007), and WB showed that HAdV-7 could up regulate the expression of pro-IL-1β and NLRP3 protein in the cells. After THP-1 was treated with NLRP3 specific inhibitor MCC950 the expression of IL-1β in the supernatant of HAdV-7 infected cells were significantly inhibited ( P=0.002) 7). Toll-like receptor (TLR)2, TLR4 and TLR7/9 signal transduction inhibitors were used respectively to inhibit HAdV-7 infection of THP-1. The result showed that TLR4 signal transduction was inhibited, and the expression level of IL-1 β in cell supernatant was significantly decreased ( P=0.0122). Using reactive oxygen species (ROS) inhibitor, cathepsin B inhibitor, or K + outflow inhibitor to inhibit the infection of THP-1 differentiated macrophages by HAdV-7, the result showed that when cathepsin B was inhibited ( P=0.0292), or K + outflow was inhibited (KCl, P=0.0022; glibenclamide, P=0.0275), the expression level of IL-1 β in the supernatant was significantly decreased. Conclusions:HAdV-7 infection of THP-1 cells can activate NLRP3 inflammasome. The first signal of NLRP3 activation is transmitted by TLR4, and the second signal is mainly activated by K + outflow and cathepsin B release.
