Background Various noninvasive liver fibrosis assessment tools are available. Here, we evaluated the performance of the asparagine aminotransferase‐to‐platelet ratio index (APRI), the fibrosis‐4 index (FIB‐4), transient elastography (TE), and the globulin–platelet (GP) ratio for identifying liver fibrosis in patients with hepatitis B virus (HBV) infection. Methods A total of 146 patients were assessed using TE, FIB‐4, APRI, the GP ratio, and liver biopsy. Three patient grouping methods were applied: any fibrosis (AF; F0 vs. F1/2/3/4); moderate fibrosis (MF; F0/1 vs. F2/3/4); and severe fibrosis (SF; F0/1/2 vs. F3/4). Receiver operating characteristic (ROC) curve analysis, univariate analyses, and multivariate logistic regression were conducted. Results Regardless of patient‐grouping method, the area under the curve (AUC) of TE and the GP ratio were similar. Using the AF grouping method, the GP ratio showed superior performance compared with APRI and FIB‐4: the AUCs for the GP ratio, TE, APRI, and FIB‐4 were 0.76, 0.75, 0.70, and 0.66, respectively. Using the MF grouping method, the GP ratio also showed superior performance compared with APRI and FIB‐4: the AUCs for the GP ratio, TE, APRI, and FIB‐4 were 0.66, 0.68, 0.57, and 0.53, respectively. Using the SF grouping method, the AUCs for the GP ratio, TE, APRI, and FIB‐4 were not significantly different. Conclusion Compared with FIB‐4 and APRI, the GP ratio had higher accuracy for identifying liver fibrosis, especially early‐stage fibrosis, in patients with HBV infection.
Background Although China has entered the post-malaria-elimination era, imported cases remain a public health concern in China. Methods We retrospectively analyzed data from cases of imported malaria from January 2017 to December 2020 in Chengdu Public Health Clinical Center. We assessed potential clinical, epidemiological, geographical, and seasonal effects on duration of hospital stay. Cox proportional hazards model was used to identify predictive factors for prolonged hospital stay. Multivariate logistic regression was used to assess the potential risk factors associated with severe cases. Results The highest number of imported cases of malaria were from the Democratic Republic of the Congo (23%, 34/150) and most patients (74%, 26/34) were infected by Plasmodium falciparum. The Edwards test indicated no significant seasonality in imported cases of malaria (χ2 = 2.51, p = 0.28). Bacterial infection (adjusted hazard ratio [aHR] for discharge = 0.58, p = 0.01) and thrombocytopenia (aHR = 0.66, p = 0.02) were risk factors for prolonged hospital stay. The C-reactive protein (OR = 1.02, p = 0.01) and procalcitonin (OR = 1.03, p = 0.01) were risk factors for severe cases. Conclusions Bacterial infection and thrombocytopenia are risk factors for prolonged hospital stay among imported malaria cases. The C-reactive protein and procalcitonin level were risk factors for severe cases.
Background and Aims:The goal of this study was to investigate the mechanism by which the long noncoding RNA MALAT1 inhibited hepatocyte proliferation in acute liver injury (ALI). Methods: Lipopolysaccharide (LPS) was used to induce an ALI cellular model in HL7702 cells, in which lentivirus vectors containing MALAT1/EZH2/GFER overexpression or knockdown were introduced. A series of experiments were performed to determine their roles in liver injury, oxidative stress injury, and cell biological processes. The interaction of MALAT1 with EZH2 and enrichment of EZH2 and H3K27me3 in the GFER promoter region were identified. Rats were treated with MALAT1 knockdown or GFER overexpression before LPS induction to verify the results derived from the in vitro assay. Results: MALAT1 levels were elevated and GFER levels were reduced in ALI patients and the LPS-induced cell model. MALAT1 knockdown or GFER overexpression suppressed cell apoptosis and oxidative stress injury induced cell proliferation, and reduced ALI. Functionally, MALAT1 interacted directly with EZH2 and increased the enrichment of EZH2 and H3K27me3 in the GFER promoter region to reduce GFER expression. Moreover, MALAT1/EZH2/GFER was activated the AMPK/mTOR signaling pathway. Conclusion: Our study highlighted the inhibitory role of reduced MALAT1 in ALI through the modulation of EZH2-mediated GFER.
BackgroundChina had entered post-elimination era for malaria, however, the imported cases are continuously are a public health concern as the increasing number of cases. In this study we studied the potential predictive factors for prolonged hospital stay for imported malaria patients. Material and MethodsWe retrospectively collected patients of imported malaria cases data from 2017-2020 in our hospital. we analyzed the data from clinical, epidemiological, geographical, and seasonal points of view, and used cox proportional hazard model to find the predictive factors for prolonged hospital stay.ResultsWe found most of imported cases were from Democratic Republic of the Congo(23%, 34/150) and most cases 74%(26/34) were infected by P. falciparum. Through Edwards Test, no significant seasonality of imported cases were found(χ2 =2.51 p-value= 0.28). We found bacterial infection(HR=0.58, p-value=0.01) and thrombocytopenia(HR=0.66, p-value=0.02) were protective factors for discharge, that were, the risk factors for prolonged hospital stay.ConclusionsThe imported cases are the major risk of malaria in post-elimination era of China. The bacterial infection and thrombocytopenia were the risk factors for prolonged hospital stay.
