Sensitivity baseline establishment and resistance risk assessment of Botrytis cinerea from Panax ginseng to prochloraz / 中国中药杂志

This study aimed to establish the baseline sensitivity of Botrytis cinerea from Panax ginseng to prochloraz, and ensure the fitness of prochloraz-resistant mutants and the cross-resistance of B. cinerea to prochloraz and commonly used fungicides for the prevention and control of gray mold including boscalid, pyraclostrobin, iprodione, and pyrimethanil. The sensitivity of B. cinerea from P. ginseng to fungicides was determined by the mycelial growth rate method. The prochloraz-resistant mutants were screened out through fungicide domestication and ultraviolet(UV) induction. The fitness of resistant mutants was determined through the stability of subculture, mycelial growth rate, and pathogenicity test. The cross-resistance between prochloraz and the four fungicides was determined by Person correlation analysis. The results showed that all B. cinerea strains tested were sensitive to prochloraz, and the EC_(50) value ranged from 0.004 8 to 0.062 9 μg·mL~(-1), with an average of 0.022 μg·mL~(-1). The sensitivity frequency distribution diagram showed that 89 B. cinerea strains were located within the main peak with a continuous single peak curve, and the average EC_(50) value of 0.018 μg·mL~(-1) was taken as the baseline sensitivity of B. cinerea to prochloraz. The fungicide domestication and UV induction obtained 6 resistant mutants, among which 2 strains were unstable and the other 2 strains showed decreased resistance after multiple generations of culture. Furthermore, the mycelial growth rate and spore yield of all resistant mutants were lower than those of their parents, and the pathogenicity of most mutants was lower than that of their parents. In addition, prochloraz had no obvious cross-resistance with boscalid, pyraclostrobin, iprodione, and pyrimethanil. In conclusion, prochloraz has great potential for controlling gray mold in P. ginseng, and the resistance risk of B. cinerea to prochloraz is low.

Study of clinical characteristics in patients with gp210 antibody-positive primary biliary cholangitis / 中华肝脏病杂志

Objective: To analyze the clinical characteristics and prognostic value of liver function in a large samples of patients with anti-glycoprotein 210 (gp210 antibody) positive primary biliary cholangitis (PBC). Methods: A retrospective study was performed on 931 PBC cases in Beijing You'an Hospital affiliated to Capital Medical University from 2010 to 2019. According to the detection of gp210 antibody, 318 cases were divided into gp210 antibody positive group (positive group) and 613 cases were divided into gp210 antibody negative group (negative group). The differences in demographic, medical history, clinical indicators, B-ultrasound and pathological indicators as well as the histopathological basis were compared between the two groups. SPSS 16.0 software was used for statistical analysis. Measurement data were analyzed by t-test or rank sum test, and enumeration data by χ2 test. Multivariate analysis was used for logistic test, and and survival analysis was used for prognosis. Results: The positive and the negative groups were compared. The ratio of male to female was significantly higher in positive than negative group (1:5.35 vs. 1:9.73, P＜0.05), and the difference was statistically significant. The proportion of hormone use in history of past diagnosed and treated was higher in positive than negative group (12.9% vs. 3.47%, P＜0.05), and the difference was statistically significant. The detection of biochemical indexes such as alanine aminotransferase (ALT), aspartate aminotransferase (AST), total bilirubin (TBIL), alkaline phosphatase (ALP), glutamyl transpeptidase (GGT) were higher in positive than the negative group (51.1 U/L vs. 41.1 U/L, 62.6 U/L vs. 49.6 U/L, 24.1 μmol/L vs. 17.9 μmol/L, 228.3 U/L vs. 169.6 U/L, 203.9 U/L vs. 147.6 U/L), (P＜0.05), and the differences were statistically significant. Antinuclear antibody (ANA)-positive rate, high titer ratio and immunoglobulin G (IgG) levels were higher in positive than negative group (95.2% vs. 81.6%, 69.7% vs. 48.8%, 17.2 g/L vs. 16.2 g/L), (P＜0.05), and the differences were statistically significant. The incidence of liver failure was higher in positive than negative group (P＜0.05). CK7 and inflammation score were higher in positive group than negative group in liver histopathological observations (0.83±0.53 vs. 0.28±0.47; 1.06±0.39 vs. 0.54±0.65), (P＜0.05), and the differences were statistically significant. Conclusion: The illness condition of patients with gp210 antibody positive PBC is more severe than patients with gp210 antibody negative PBC, and the incidence of liver failure is significantly increased. Cholangiocytes may be the histopathological basis of the clinical characteristics of gp210 antibody positive PBC patients.

Xijiao Dihuang Decoction () and Rehmannia glutinosa Libosch. protect mice against lipopolysaccharide and tumor necrosis factor alpha-induced acute liver failure / 中国结合医学杂志

OBJECTIVE@#To investigate the hepatoprotective effect of Xijiao Dihuang Decoction (, XJDHD) on lipopolysaccharide (LPS)- and tumor necrosis factor alpha (TNF-α)-induced acute liver failure (ALF) as well as the underlying mechanism of action, and to clarify the key herbs and components of XJDHD.@*METHODS@#LPS/D-galactosamine (D-GalN) or TNF-α/D-GalN were intraperitoneally injected into C57BL/6J mice to induce ALF. Simultaneously, XJDHD or its individual herbs and components were orally administered. Survival rates, transaminase levels in serum, and hepatic histology were examined to evaluate the effects of XJDHD. The terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling (TUNEL) assay and real-time polymerase chain reaction were additionally performed to expound the mechanism underlying the anti-apoptotic activity of XJDHD.@*RESULTS@#Oral administration of XJDHD protected mice from lethal liver failure induced by LPS and TNF-α, with notable amelioration of liver injury in histology and a significant decrease in transaminase levels in serum. XJDHD significantly inhibited apoptosis of hepatocytes and enhanced expression of the antiapoptosis genes, c-Flip, Iap1, Gadd45b and A20. In addition, Rehmannia glutinosa Libosch. was identified as the key herb of XJDHD and galactose as the effective component of Rehmannia glutinosa Libosch. that protects against ALF.@*CONCLUSIONS@#XJDHD inhibits TNF-α-induced apoptosis of hepatocytes by promoting the expression of nuclear factor κ B-regulated anti-apoptotic genes. Rehmannia glutinosa Libosch. is the effective herb of XJDHD and galactose is an active component in this protection.

Protective Effect of Ganshuang Granules () on Liver Cirrhosis by Suppressing Regulatory T Cells in Mouse Model / 中国结合医学杂志

OBJECTIVE@#To investigate the potential antifibrotic mechanisms of Chinese medicine Ganshuang Granules (, GSG) and to provide clinical therapeutic evidence of its effects.@*METHODS@#A cirrhotic mouse model was established by intraperitoneally injecting a mixture of CCl (40%) and oil (60%) at 0.2 mL per 100 g of body weight twice a week for 12 weeks. After 12-week modeling, GSG was intragastric administrated to the mice for 2 weeks, and the mice were divided into low-, medium- and high-dose groups at doses of 1, 2 and 4 g/(kg·day), respectively. Liver morphology changes were observed using Masson's trichrome staining and B-ultrasound. The levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST) and hyaluronic acid (HA) in serum were detected using an automatic biochemistry analyzer. The expressions of desmin, smooth muscle actin (SMA) and Foxp3 in liver were detected by immunoflfluorescence. The regulatory T cell (Treg) frequency was determined through flflow cytometry analysis. Collagen-I, SMA, IL-6, tumor necrosis factor α (TNF-α), interleukin (IL)-1β and transforming growth factor β1 (TGF-β1) expression levels were measured using quantitative polymerase chain reaction (qPCR).@*RESULTS@#Masson's staining result showed fewer pseudolobule structures and fibrous connective tissue in the GSG-treatment groups than in the spontaneous recovery group. Ultrasonography showed that GSG treatment reduced the number of punctate hyperechoic lesions in mice cirrhotic livers. The serum ALT, AST, HA levels were significantly ameliorated by GSG treatment (ALT: F=8.104, P=0.000; AST: F=7.078, P=0.002; and HA: F=7.621, P=0.001). The expression levels of collagen-I and SMA in the cirrhotic livers were also attenuated by GSG treatment (collagen-I: F=3.938, P=0.011; SMA: F=4.115, P=0.009). Tregs, which were elevated in the fibrotic livers, were suppressed by GSG treatment (F=8.268, P=0.001). The expressions of IL-6, TNF-α and IL-1β increased, and TGF-β levels decreased in the cirrhotic livers after GSG treatment (IL-6: F=5.457, P=0.004; TNF-α: F=6.023, P=0.002; IL-1β: F=6.658, P=0.001; and TGF-β1: F=11.239, P=0.000).@*CONCLUSIONS@#GSG promoted the resolution/regression of cirrhosis and restored liver functions in part by suppressing Treg cell differentiation, which may be mediated by hepatic stellate cells.

Clinical Model for Predicting Hepatocellular Carcinomas in Patients with Post-Sustained Virologic Responses of Chronic Hepatitis C: A Case Control Study

BACKGROUND/AIMS: No clinical model exists to predict the occurrence of hepatocellular carcinoma in sustained virologic response-achieving (HCC after SVR) patients with chronic hepatitis C (CHC). METHODS: We performed a case-control study using a clinical database to research the risk factors for HCC after SVR. A predictive model based on risk factors was established, and the area under the receiver operating characteristic curve (AUC) was calculated. RESULTS: In the multivariate model, an initial diagnosis of compensated cirrhosis and post-SVR albumin reductions of 1 g/L were associated with 21.7-fold (95% CI, 4.2 to 112.3; p0, an AUC of 0.880, a sensitivity of 0.833, a specificity of 0.896, and a negative predictive value of 0.956. CONCLUSIONS: An initial diagnosis of compensated cirrhosis combined with a post-SVR albumin value of ≤36.0 g/L predicts the occurrence of HCC after SVR in patients with CHC.

Detection of antigen-epitope-specific cytotoxic T lymphocytes in patients with hepatitis B virus infection by enzyme linked immunospot assay / 中华预防医学杂志

<p><b>OBJECTIVE</b>To investigate the ability of secreting interferon-gamma (IFN-gamma) of the peripheral blood monocular cells (PBMC) stimulated by hepatitis B virus (HBV)-specific cytotoxic T lymphocyte (CTL) epitopes peptides and to analyze the difference of CTL immune response in patients with HBV infection.</p><p><b>METHODS</b>Four HLA-A2-restricted HBV cytotoxic T lymphocyte epitopes [Tp: HBV polymerase 575-583 (FLLSLGIHL), Te1: envelope 28-39 (IPQSLDSWWTSL), Te2: envelope 183-191 (FLLTRILTI) and Tc: core 18-27 (FLPSDFFPSV)] were synthesized. Human leucocyte antigen (HLA)-A2 typing was detected by Flow cytometry. PBMCs which were isolated from patients with chronic hepatitis B(CHB), patients with chronic severe hepatitis B(CSH), subjects with past HBV infection(N1) and healthy blood donors (N2) were stimulated by the four HLA-A2-restricted HBV CTLs epitopes. Enzyme linked immunospot (ELISPOT) assay was used to detect the frequency of secreting IFN-gamma CTL in each group.</p><p><b>RESULTS</b>(1) HLA-A2 typing: 20 of 44 patients with CHB (45.5%) were HLA-A2 positive, 10/18 (55.6%) in CSH and 6/10 (60%) in group N1 were HLA-A2 positive.10 healthy blood donors' HLA-typing was detected in the early study.(2) ELISPOT results: (1) The total responses to the four epitopes in CHB, CSH, N1 and N2 groups were 50% (10/20), 10% (1/10), 83.3% (5/6) and 10% (1/10), respectively. The response in N1 group was significantly higher than that in CSH group (chi(2) = 9.000, P = 0.008) and N2 group (chi(2) = 9.000, P = 0.008). (2) The CTL average magnitude response to Tp epitope, Te1 epitope, Te2 epitope and Tc epitope was also significantly higher in past HBV infection group (77 SFC/10(6) PBMC, 59 SFC/10(6) PBMC, 100 SFC/10(6) PBMC and 57 SFC/10(6) PBMC, respectively) than that of CSH group (10 SFC/10(6) PBMC, 0 SFC/10(6) PBMC, 0 SFC/10(6) PBMC and 20 SFC/10(6) PBMC respectively, all P < 0.01) and N2 group (15 SFC/10(6) PBMC, 0 SFC/10(6) PBMC, 22 SFC/10(6) PBMC and 30 SFC/10(6) PBMC respectively, all P < 0.01).</p><p><b>CONCLUSION</b>This study indicates that the T cell immune response to HBV-specific epitopes might be detected either in patient with chronic HBV infection or with previous HBV infection. This response should be much higher in patients with past HBV infection, even the virus had been cleared for long time. These results demonstrate that HBV-specific CTL might play an important role in the clearance of the virus.</p>

Immunological characteristics of primary biliary cirrhosis patients / 中华肝脏病杂志

<p><b>OBJECTIVE</b>To study the clinical significance of the immunological characteristics in patients with primary biliary cirrhosis (PBC).</p><p><b>METHODS</b>3000 patients with abnormal liver functions were examined for anti-nuclear antibodies (ANA), anti-mitochondrial antibodies (AMA), anti-smooth muscle antibodies (SMA) and anti-liver kidney microsomal antibody (LKM) using immunofluorescent assays (IFA). LKM-1, liver cytosolic-1 (LC-1), soluble liver antigen (SLA)/liver- pancreas antigen (LP) and subtype of AMA (M2, M4, M9) as well as ANA profile were detected by an immune blotting assay and an enzyme-linked immune absorbent assay (ELISA), respectively. Cytokines were tested by flow cytometry.</p><p><b>RESULTS</b>Of the 3000 patients with liver diseases, 52 (1.7%) were diagnosed with PBC. All the PBC cases were positive for AMA and M2. 94% of them showed high titer of AMA (> or = 1:320), and in 79% of them M2 was >200 RU/L, and 78% of them were ANA positive. Three main fluorescent patterns of ANA seen were nuclear membrane, nuclear dots and centromere patterns. Sjogren's Syndrome A/B (SS-A/B), homogenous, nucleolar or nuclear granular patterns were seen in only a few patients. IgM, ALP and GGT in PBC patients were significantly higher than those in hepatitis B related liver cirrhosis patients. The levels of IL-6, IL-10, TNF-alpha and IFN-gamma in PBC patients were higher than in the normal controls. Among the 52 PBC patients, 5 had autoimmune liver disease overlap syndromes. Two of them were SLA/LP positive, indicated as AIH type III and PBC overlapping, and 1 was LKM-1 positive showing AIH type II overlapping PBC, and 2 had ANA positive and were identified as AIH and PBC by liver biopsy.</p><p><b>CONCLUSION</b>The percentage of PBC in Chinese liver disease patients is about 1% to 2%. Most of the PBC patients have high levels of AMA and AMA-M2, IgM, ALP, GGT and several cytokines, indicating that abnormality of humeral and cellular immunity may be associated with the pathogenesis of PBC.</p>
