Objective To investigate the expression of miR-495 and its effect on MHCC-97H hepatocellular carcinoma cells. Methods Fifty-six hepatocellular carcinoma tissue specimens (HCC group) and 40 normal liver tissue specimens (control group) preserved in our hospital from January 2017 to January 2018 were selected. Reverse transcription real-time fluorescent quantitative PCR (qRT-PCR) was used for miR-495 expression detection. MHCC-97H HCC cells were randomly selected and then divide into control group, blank plasmid group and transfection group. The blank plasmid group was transfected with blank plasmid, and the transfection group was transfected with miR-495 inhibitor. The expression of miR-495 in each group of cells were detected using qRT-PCR. CCK method was used to detect each group proliferation activity. Transwell cell migration assay was used to detect each group migration ability. Analysis of variance was used for comparison between multiple groups. Furthermore, LDS-t test was used for pairwise comparison, tly lower than that of control group and blank plasmid group (P less then 0.05). Conclusion miR-495 high expression has certain relationship with clinicopathological characteristics of HCC tissues. In addition, miR-495 has a certain effect on the proliferation and migration ability of MHCC-97H HCC cells.Objective To analyze the correlation between indocyanine green retention rate at 15 minutes (ICG-R15) and modified Scheuer score in liver tissues of patients with hepatitis B e antigen-positive/negative chronic hepatitis B (CHB), and further explore the indocyanine green clearance test (ICGCT) applied value in judging the progress of CHB-related liver disease. Methods 407 HBeAg (+) / HBeAg (-) CHB inpatients with normal or slightly elevated serum alanine aminotransferase (ALT) [ less then 2 times the upper limit of normal (ULN)] and modified Scheuer score were collected, and divided into mild liver disease group (M group, 131 cases, modified Scheuer score less then G2S2) and progressive liver disease group (A group, 276 cases, modified Scheuer score≥G2 and / or S2). Furthermore, the groups were sub-divided into HBeAg (+) - M group, HBeAg (-) - M group, HBeAg (+) - A group and HBeAg (-) - A group. The correlation between ICG-R15 and modified Scheuer score was analyzed retrospectively. The data were analyzed progression to modified Scheuer score ≥ G2 and / or ≥S2 in HBeAg (+) / HBeAg (-) CHB patients with normal or slightly elevated ALT.Objective To investigate and analyze the energy metabolism characteristics and the correlation between energy metabolism and the risk of secondary bacterial infection in patients with hepatitis B virus-related chronic liver disease (HBV-CLD). Methods Data of 183 cases admitted to the Mengchao Hepatobiliary Hospital of Fujian Medical University from November 2017 to November 2020 were retrospectively analyzed. 79 cases of chronic hepatitis B, 51 cases of hepatitis B-related liver cirrhosis, and 53 cases of hepatitis B-related liver failure were collected. Among them patients with liver failure and decompensated liver cirrhosis were defined as severe liver disease group. The Quark RMR indirect calorimetry (COSMED Corporation, Italy) was used to exam the patients' energy metabolism condition, and the incidences of secondary bacterial infection of the patients during hospitalization were recorded. Shapiro-Wilk test and normal QQ plot were used to analyze the normal distribution of continuous variable data, which e npRQ reduction is related to the risk of secondary bacterial infection in patients with severe liver disease, and thus can be used as a clinical prognostic indicator.Objective To analyze and summarize the characteristics of liver pathology and their relation to clinical markers and further explore noninvasive markers of liver fibrosis in children with chronic hepatitis B. Methods Data of 80 hospitalized children with chronic hepatitis B who underwent liver biopsy without antiviral treatment from 2011 to 2020 were retrospectively analyzed. Inflammation and liver fibrosis characteristics were analyzed in children of different ages and genders. Variables with good correlation with liver fibrosis stage were selected to establish a non-invasive diagnostic score of liver fibrosis in children. Measurement data was used to compare the t-test or rank sum test. Mantel-Haenszel χ (2) test was used for bidirectional ordered grouping data. Spearman's rank correlation test was used for rank correlation analysis. Receiver operating characteristic curve (ROC) was used to evaluate the diagnostic value of the newly established diagnostic score in children with liver fibrosis. Results The m5, it can be diagnosed as S0, and 1.5 ≤ score less then 3.5, it can be diagnosed as S1; 3.5 ≤ score less then 5.5, the diagnosis of fibrosis is S2; score≥ 5.5, the diagnosis of fibrosis is S≥3. see more The sensitivity and specificity were 80%, 83%, 86%, and 53%, 55%, 67%, respectively. Conclusion The incidence of liver tissue inflammation in children with chronic hepatitis B with elevated and fluctuating transaminase levels is high, and the pathological changes of liver tissue aggravate with the age of the children. GGT, GPR and HBeAg have a good correlation with liver fibrosis in children with chronic hepatitis B. Therefore, combining the above-mentioned markers to establish a new noninvasive diagnostic score has certain diagnostic value for liver fibrosis stage S0-S3 in children with chronic hepatitis B.Objective To explore the protective effect of vitamin D in acute liver failure through a mouse model. Methods Acute liver failure was induced by combining D-galactosamine (D-GalN) lipopolysaccharide (LPS) to observe the effect of long-term vitamin D deficiency on liver injury and inflammatory signals in a mouse model. Acute liver failure was induced by thioacetamide (TAA) to observe the effect of vitamin D deficiency on the survival rate, and further high-dose of vitamin D supplementation protective effect was determined in a mouse model. Liver function was evaluated by measuring serum alanine aminotransferase (ALT), aspartate aminotransferase (AST) and liver inflammation by hematoxylin-eosin staining. The expressions of tumor necrosis factor (TNF-α), interleukin (IL) -1β, NOD-like receptor family, pyrin domain containing 3 (NLRP-3), chemokines (CCL2, CXCL1 and CXCL2), etc. in liver tissues were detected by RT-qPCR. The quantitation of macrophages in liver tissue was detected by immunohistochemistry. The comparison between groups were performed by t-test.
