Mdr2 knockout mice is a liver disease model, which causes cholestasis due to the lack of phospholipids in the bile. At present, it is not only used for the study of human homologous MDR3 gene, but also widely used as an animal model of liver diseases such as primary sclerosing cholangitis, liver fibrosis, progressive familial intrahepatic cholestasis, liver cancer. Herein, we review the Mdr2 knockout mice physiological characteristics and its application in liver disease research.Objective To analyze the factors influencing radiation-induced liver injury after receiving Cyberknife stereotactic radiotherapy in patients with primary hepatocellular carcinoma. Methods 278 cases with primary hepatocellular carcinoma from July 2016 to April 2019 were prospectively enrolled. Stereotactic radiosurgery with a prescription dose of 48-55gy/5-8 times were given. Liver function, coagulation function, Child-Pugh score, and liver imaging changes were dynamically observed before and after treatment to evaluate the occurrence of radiation-induced liver injury. Logistic regression model was used to analyze the factors influencing radiation-induced liver injury. Results Among 278 cases, 3 cases of tumor progression were excluded, and a total of 275 cases were included for analysis. The overall survival rate after 8 months of treatment was 100%. Among them, 22 cases were diagnosed as radiation-induced liver injury, with an incidence rate of 8%, and all cases were recovered after symptomatic treatment. Multivariate analysis result suggested that the peripheral white blood cell count was factors influencing the occurrence of radiation-induced liver injury. Conclusion Cyberknife stereotactic radiotherapy has a low incidence of radiation-induced liver injury in patients with liver cancer, and it is a relatively safe treatment method. Patients with low peripheral white blood cell counts before treatment should be closely monitored for early detection and treatment.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. The sensitivity and specificity were 80%, 83%, 86%, and 53%, 55%, 67%, respectively. click here 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 compre, high-dose of vitamin D has a certain hepatoprotective effect, which can significantly improve liver necrosis condition and inhibit inflammation. Therefore, adequate vitamin D can retain liver physiological balance to resist liver injury.Objective To investigate the effect of R2* value on the evaluation of different degrees of hepatic warm ischemia-reperfusion injury (WIRI) and liver regeneration after partial hepatectomy in rabbits. Methods Thirty healthy adult male New Zealand White rabbits were randomly divided into five groups. Hepatic caudal lobectomy was performed in both the control and the warm ischemia time-dependent variation group. After reperfusion, routine MRI and BOLD MRI scans were performed for each group at 6 h, 3 d, 7 d, 14 d and 30 d, respectively, and then R2* value and liver regeneration rate (LRR) were measured and calculated. After 30 days of scanning, the serum levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST) and lactate dehydrogenase (LDH), malondialdehyde (MDA), superoxide dismutase (SOD), myeloperoxidase (MPO), tumor necrosis factor - α (TNF - α), interleukin-6 (IL-6) and proliferating cell nuclear antigen (PCNA) were detected in frozen rabbit liver tissues, and the pathological sections were collected. Repeated measures analysis of variance was used to evaluate the changes of R2* value, LRR and its influencing factors at different follow-up time and warm ischemia time in each group. Pearson's or Spearman's correlation analysis was used to evaluate the correlation of R2* value with LRR and various biochemical indexes. Results The interaction between different follow-up time and warm ischemia time (F = 24.600, P 0.05). Conclusion The R2* value may be used for noninvasive and quantitative evaluation of microstructural changes of WIRI and affect liver regeneration after partial hepatectomy in rabbits. A certain degree of WIRI (≤30 min) after partial hepatectomy can promote liver regeneration in rabbits. Furthermore, as the warm ischemia time prolongs, the promoting effect becomes more pronounced, and if the warm ischemic time exceeds 30 minutes, the promoting effect is significantly reduced.Objective To preliminary explore the changes in blood system in pyrrolizidine alkaloids (PAs)-related liver damage. Methods General situation, liver function, biochemical blood test, routine blood test, coagulation function markers, etc., of 77 cases with drug-induced liver damage admitted to the Zhongshan Hospital Affiliated to Fudan University from 2012 to 2019 were retrospectively analyzed. Patients' were divided into PA group, other traditional Chinese medicine group and Western medicine group according to their medication history. Simultaneously, the changes in liver function were observed in the established mice model of monocrotaline-induced liver damage. Liver tissues HE staining and blood routine indexes were observed. Results 24 cases received PA, 24 cases received other traditional Chinese medicine, and 29 cases received western medicine. Alanine aminotransferase was lower in PA group than the other two groups (P less then 0.05), and the total bilirubin and direct bilirubin were significantly lower than the other traditional Chinese medicine group (P less then 0.
