Effect of Direct-acting Antivirals Treatment on Renal Function Among HCV-infected Patients / 中山大学学报(医学科学版)

； ObjectiveTo explore the effect of direct-acting antiviral treatment on renal function in patients with chronic hepatitis C. MethodsA total of 123 HCV-infected patients receiving DAAs treatment at the Third Affiliated Hospital of Sun Yat-sen University from January 2017 to December 2021 were included in this study. To explore the renal function in patients with chronic hepatitis C treated with direct-acting antivirals， serum creatinine values were collected before， during and after the treatment， which were used to estimate the eGFR by the MDRD equation to assess the changes in renal function. ResultsOf the 123 patients enrolled， 67.5%（n=83）were male， and the mean age of participants was （50±11） years old. The mean follow-up period was 24 weeks . Comorbidities included cirrhosis in 26.8%， and diabetes in 10.6%. Meanwhile， 11.4% of the cohort had eGFR < 60 mL/（min ·1.73 m2）， 33.3% of the cohort had eGFR 60 to 90 mL/（min ·1.73 m2）， and 55.3% had eGFR≥90 mL/（min ·1.73 m2）. No decrease in renal function was seen among all the HCV-infected patients at the end of treatment or the follow-up period after treatment. However， compared with the eGFR at the baseline， eGFR in CKD2 patients in the follow-up period was improved 【（88.65±15.52） mL/（min ·1.73 m2）vs （78.12 ±7.60） mL/（min ·1.73 m2）， P< 0.001】. And 14.6% （n=18） of patients experienced progressive deterioration of renal function. Logistic regression analysis showed that diabetes could predict the deterioration of renal function （OR=4.663， P=0.016）. ConclusionsOur study shows renal function is not impair among HCV-infected patients following DAAs treatment， and renal function in CKD2 patients have improvements. However， HCV-infected patients with diabetes mellitus are at a high risk of renal impairment and closely monitoring of renal function is still needed.

Association of intestinal microecology with the development and progression of autoimmune hepatitis / 临床肝胆病杂志

Autoimmune hepatitis （AIH） is an autoimmune disease characterized by chronic liver inflammation， with a gradually increasing incidence rate， and its social and medical burdens cannot be neglected. Intestinal microecology is becoming a research hotspot in the field of autoimmune disease. In recent years， it has been believed that changes in intestinal microecology can cause changes in autoimmune state， microbial metabolites， and intestinal barrier， which is one of the driving factors for the onset of AIH. Early diagnosis and correct treatment can help to improve the prognosis of AIH patients. This article introduces the characteristics of gut microbiota in AIH patients， elaborates on the impact of intestinal microflora imbalance on the pathogenesis of AIH， and briefly describes related treatment regimens from the perspective of intestinal microecology， so as to comprehensively understand and explain the role of intestinal microecology in AIH and the impact of intestinal microecology balance on the pathogenesis， diagnosis， and treatment of AIH.

Effect of treatment with direct-acting antiviral agents on the prognosis of extrahepatic diseases in patients with hepatitis C / 临床肝胆病杂志

The prognosis of patients with hepatitis C virus infection depends not only on liver lesions， but also on extrahepatic sequelae. Direct-acting antiviral agents （DAAs）， as the first-line drugs in the treatment of hepatitis C， have helped more and more patients achieve sustained virologic response and clinical cure， but its effect on the prognosis of extrahepatic diseases remains unclear. This article reviews the effect of DAAs treatment on the prognosis of extrahepatic diseases in patients with hepatitis C and points out that long-term follow-up monitoring is still required for patients with hepatitis C after cure.

Effect of Dendrobium officinale leaf fermentation fluid on a mouse model of alcoholic hepatitis and its mechanism of action / 临床肝胆病杂志

ObjectiveTo investigate the intervention mechanism of Dendrobium officinale leaf fermentation fluid in mice with alcoholic hepatitis. MethodsA total of 70 healthy male C57BL/6J mice， aged 6-8 weeks， were randomly divided into normal group， model group， liquid feed control group， silybin group， and low-， middle-， and high-dose Dendrobium officinale leaf fermentation fluid groups， with 10 mice in each group. The mice in the normal group were given normal diet， and those in the other groups were given Lieber-DeCarli classic liquid diet for 8 weeks to induce alcoholic hepatitis. During modeling， the mice in the low-， middle-， and high-dose Dendrobium officinale leaf fermentation fluid groups were given Dendrobium liquid manufactured by Warmen Pharmaceutical， and the mice in all the other groups were given pure water； the mice in the normal group， the model group， and the liquid feed control group were given normal saline by gavage， those in the silybin group were given silybin 0.25 mL/10 g by gavage， and those in the low-， middle-， and high-dose Dendrobium officinale leaf fermentation fluid groups were given Dendrobium officinale leaf fermentation fluid at a dose of 0.125 mL/10 g， 0.250 mL/10 g， and 0.375 mL/10 g， respectively， by gavage， once a day. At week 8， chloral hydrate was injected intraperitoneally for anesthesia， and blood samples were collected from the eyeball. After serum was separated， the biochemical method was used to measure the levels of aspartate aminotransferase （AST） and alanine aminotransferase （ALT）； HE staining and oil red staining were used to observe liver histopathology and lipid accumulation in mice； multiplex Luminex assay was used to measure the serum levels of interleukin-6 （IL-6）， interleukin-1β （IL-1β）， tumor necrosis factor-α （TNF-α）， and CCL2； quantitative real-time PCR， Western blot， and immunofluorescence assay were used to measure the protein expression levels of NLRP3， caspase-1， caspase-11， gasdermin D （GSDMD）， N-terminal gasdermin D （GSDMD-N） in liver tissue. A one-way analysis of variance was used for comparison of continuous data between multiple groups， and the least significant difference t-test was used for further comparison between two groups. ResultsCompared with the normal group， the model group had significant increases in the serum levels of AST， ALT， IL-6， IL-1β， TNF-α， and CCL2 （all P<0.05）， and compared with the model group， the high-dose Dendrobium officinale leaf fermentation fluid group had significant reductions in the serum levels of AST， ALT， IL-6， IL-1β， TNF-α， and CCL2 （all P<0.05）. HE staining showed that the model group had disordered structure of hepatic lobules， with a large number of steatosis vacuoles and massive cell necrosis， and compared with the model group， the high-dose Dendrobium officinale leaf fermentation fluid group had alleviation of liver histopathological injury， intact structure of most hepatic lobules， and a small amount of inflammatory cell infiltration. Oil red staining showed that the model group had accumulation of large and small lipid droplets in the liver and a significant increase in liver fat content， and compared with the model group， the high-dose Dendrobium officinale leaf fermentation fluid group had significant alleviation of hepatic steatosis， with the presence of sporadic small lipid droplets. Immunofluorescence assay of liver tissue showed that compared with the normal group， the model group had a significant increase in the ratio of GSDMD-positive staining area in hepatocyte cytoplasm （P<0.001）， and compared with the model group， the high-dose Dendrobium officinale leaf fermentation fluid group had a significant reduction in such ratio in hepatocyte cytoplasm （P<0.001）. Quantitative real-time PCR showed that compared with the normal group， the model group had significant increases in the protein expression levels of NLRP3， caspase-1， caspase-11， GSDMD， GSDMD-N， interleukin-18 （IL-18）， and IL-1β in liver tissue （all P<0.05）， and compared with the model group， the high-dose Dendrobium officinale leaf fermentation fluid group had significant reductions in the protein expression levels of NLRP3， caspase-1， caspase-11， GSDMD， GSDMD-N， IL-18， and IL-1 （all P<0.05）. Compared with the model group， the high-dose Dendrobium officinale leaf fermentation fluid group had significant reductions in the protein expression levels of caspase-1 and caspase-11 （both P<0.05）， with a relative expression level of caspase-1 of 1.757 （reduced by 26.6% compared with the model group） and a relative expression level of caspase-11 of 0.455 （reduced by 70.3% compared with the model group）， suggesting that caspase-11 showed a greater reduction than caspase-1. ConclusionDendrobium officinale leaf fermentation fluid can alleviate alcoholic hepatitis in mice， possibly by inhibiting the non-classical cell pyroptosis pathway mediated by caspase-11.

Preliminary identification of the cloning， expression， and function of Marmota himalayana type I interferon receptor β subunit / 临床肝胆病杂志

ObjectiveTo clone the gene of Marmota himalayana type ‍Ⅰ interferon receptor β subunit （mhIFNAR2）， and to perform antibody preparation and functional identification. MethodsRT-PCR was used for amplification in the spleen tissue of Marmota himalayana to obtain the sequence， which was cloned to the prokaryotic expression vector pRSET-B to express the recombinant protein. Electrophoresis and Western blot were used for identification. BALB/c mice were immunized with the recombinant protein to prepare the polyclonal antibody of its extracellular domain； immunohistochemistry， immunofluorescence assay， and Western Blot were used for identification， and the method of siRNA blockade was used to investigate its function. An analysis of variance was used for comparison of continuous data between multiple groups， and the least significant difference t-test was used for comparison between two groups. ResultsA fragment of mhIFNAR2 （149‍ ‍—‍ ‍1 ‍300 bp） was obtained from spleen tissue， which showed the highest homology of 98.05% in marmot. A prokaryotic expression plasmid was successfully constructed for expression of the extracellular domain of the mhIFNAR2（50-181aa） and was named pRSET-B.mhIFNAR2， and the recombinant protein expressed by this plasmid had a molecular weight of 27 kD， a purity of about 95% after purification， and a concentration of 160 μg/mL. After BALB/c mice were immunized with the purified recombinant protein， 1∶1 000 specific polyclonal antibodies were obtained， and immunohistochemistry and immunofluorescence assay showed the expression in cell membrane and cytoplasm. Among the three siRNAs synthesized， the siRNA starting from the 277 locus （siRNA277） could silence the expression of target genes and weaken the interferon signaling pathway compared with the blank control group and the negative control group （both P<0.05）. ConclusionThe fragment of mhIFNAR2 is obtained， and the polyclonal antibody for the extracellular domain of mhIFNAR2 is successfully prepared， with relatively high titer and specificity， and can be used for immunohistochemistry， immunofluorescence assay， and Western blot.

Value of serum creatinine-to-cystatin C ratio in assessing the prognosis of hepatitis B virus-related acute-on-chronic liver failure / 临床肝胆病杂志

ObjectiveTo investigate the clinical value of serum creatinine-to-cystatin C ratio （CCR） in evaluating the prognosis of hepatitis B virus-related acute-on-chronic liver failure （HBV-ACLF）. MethodsA retrospective analysis was performed for the clinical data of 130 patients with HBV-ACLF （treatment group） who were hospitalized in Department of Infectious Diseases， The First Affiliated Hospital of Soochow University， from January 2021 to November 2022. According to the treatment outcome， they were divided into survival group with 87 patients and death group with 43 patients； according to the presence or absence of infection， they were divided into infection group with 37 patients and non-infection group with 93 patients. A total of 30 individuals who underwent physical examination during the same period of time were enrolled as control group. Routine blood test results were collected on the day of admission， including white blood cell count， platelet count， neutrophil count， and lymphocyte count； serum creatinine， cystatin C， serum albumin （Alb）， and prothrombin time （PT） were observed on the day of admission and on days 5， 10， and 15 of hospitalization， and related indicators were calculated， including CCR， neutrophil-to-lymphocyte ratio （NLR）， platelet-to-lymphocyte ratio （PLR）， prognostic nutritional index （PNI）， CCR5 （CCR on day 5 after admission）， ΔCCR5 （CCR on day 5 after admission minus CCR on the day of admission）， CCR10 （CCR on day 10 after admission）， ΔCCR10 （CCR on day 10 after admission minus CCR on day 5 after admission）， CCR15 （CCR on day 15 after admission）， and ΔCCR15 （CCR on day 15 after admission minus CCR on day 10 after admission）. The above indicators were compared between the survival group and the death group and between the infection group and the non-infection group. The Mann-Whitney U test was used for comparison of continuous data between two groups， and the Kruskal-Wallis H test was used for comparison between multiple groups. The univariate and multivariate logistic regression analyses were used to investigate the influencing factors for disease prognosis； the receiver operating characteristic （ROC） curve was used to assess the value of CCR in predicting HBV-ACLF death events， and the DeLong test was used for comparison of the area under the ROC curve （AUC）. ResultsThere were significant differences in CCR， NLR， PNI， PT， and Alb at baseline between the treatment group and the healthy control group （all P<0.001）， and there were significant differences in CCR， NLR， and PT between the survival group and the death group on the day of admission （all P<0.05）. Among the 130 patients with HBV-ACLF， there were 25 in the precancerous stage， 48 in the early stage， 32 in the intermediate stage， and 25 in the advanced stage， and there were significant differences in baseline CCR， PLR， and PT between the patients in different stages of HBV-ACLF （all P<0.05）. There were significant differences in ΔCCR5 and NLR between the infection group and the non-infection group （P<0.05）， and there were significant differences in ΔCCR5， CCR10， and CCR15 between the survival group and the death group （all P<0.05）. The multivariate logistic regression analysis showed that ΔCCR5 （odds ratio ［OR］=1.175， 95% confidence interval ［CI］： 1.098‍ — ‍1.256， P<0.001）， NLR （OR=0.921， 95%CI： 0.880‍ — ‍0.964， P<0.001）， and PT （OR=0.921， 95%CI： 0.873‍ — ‍0.973， P=0.003） were independent influencing factors for the prognosis of HBV-ACLF patients. ΔCCR5 had an AUC of 0.774， a sensitivity of 0.687， and a specificity of 0.757， and the AUC of ΔCCR5+PT+NLR was 0.824， which was significantly higher than the AUC of ΔCCR5， NLR， or PT alone （all P<0.05）. ConclusionΔCCR5， NLR， and PT can reflect the condition and prognosis of patients with HBV-ACLF and are independent predictive indicators for death events in patients with HBV-ACLF. The combination ofΔCCR5， PT， and NLR has the best predictive efficiency.

Clinical features of critically ill pregnant and parturient women infected with chronic hepatitis B virus： An analysis of 41 cases / 临床肝胆病杂志

ObjectiveTo investigate the clinical features and outcomes of critically ill pregnant and parturient women with chronic hepatitis B virus （HBV） infection， and to provide clinical experience for the rescue of critically ill pregnant and parturient women and the prevention and treatment of the severe exacerbation of liver disease. MethodsA total of 41 pregnant and parturient women with chronic HBV infection who were admitted to Department of Critical Care Medicine， Nanjing Second Hospital， from March 2013 to March 2023 were enrolled in this study， and their clinical data were collected through the electronic medical record system of hospital to summarize the main causes of transfer to the intensive care unit （ICU）， the causes of death， and treatment. The independent-samples t test was used for comparison of normally distributed continuous data between two groups， and the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between two groups. The chi-square test was used for comparison of categorical data between two groups. ResultsAmong the 41 patients， 13 （31.71%） did not receive regular antenatal examination and 8 （19.51%） with a high viral load （HBV DNA ≥2×105 IU/mL） did not receive antiviral therapy. Cesarean section was the main mode of delivery in 32 patients （78.05%）； 23 patients （56.10%） had premature delivery， and 5 patients died （12.20%）. The top three causes of transfer to the ICU were liver failure， postpartum hemorrhage， and hypertensive disorders of pregnancy. Liver failure mainly occurred in late pregnancy， with hepatic encephalopathy as the most common complication （28.57%） and intrahepatic cholestasis of pregnancy as the most common comorbidity （21.43%）； among the 14 patients with liver failure， 6 （42.86%） received regular antenatal examination， and 13 （92.86%） did not receive antiviral therapy before admission. The mean length of ICU stay was 3.31±1.65 days for the patients with postpartum hemorrhage， among whom the patients with severe liver disease had coagulation disorders before delivery， which were difficult to correct after 48 hours of treatment. ConclusionPregnant and parturient women with chronic HBV infection tend to have complex conditions and a relatively high mortality rate. For pregnant and parturient women with chronic HBV infection， assessment of liver status， regular antenatal examination， and timely antiviral therapy are of vital importance to reduce severe exacerbation and mortality rate.

Correlation between serum HBV RNA and duration of treatment with nucleos（t）ide analogues in patients with chronic hepatitis B / 临床肝胆病杂志

‍ ObjectiveTo investigate the serum level of HBV RNA in untreated or treatment-experienced patients with chronic hepatitis B （CHB） and the correlation between serum HBV RNA level and the duration of antiviral therapy with nucleos（t）ide analogues （NAs）. MethodsA total of 300 patients with CHB who attended Department of Infectious Diseases in The First Affiliated Hospital of Shihezi University School of Medicine from February to July， 2022， were enrolled as subjects. Related clinical data were collected， and according to the duration of antiviral therapy， they were divided into untreated group with 73 patients， treatment duration ≤1 year group with 91 patients， and treatment duration >1 year group with 136 patients. Serum HBV RNA load， HBV DNA load， and HBsAg concentration were measured for all patients. The Mann-Whitney U test was used for comparison of continuous data between two groups， and the Kruskal-Wallis H test was used for comparison between multiple groups， further pairwise comparison using Bonferroni method； the chi-square test was used for comparison of categorical data； a Spearman correlation analysis was used to investigate the degree of correlation between various indicators. ResultsThe positive rate of HBeAg was 18.3%， and among the patients with negative HBV DNA， the patients with positive HBV RNA accounted for 44.1% （86/195）. There was a significant difference in the distribution of the serum levels of HBV RNA， HBV DNA， and HBsAg between the positive HBeAg group and the negative HBeAg group （Z=10.740， 6.300， and 7.280， all P<0.05）. There was a significant difference in the distribution of DNA level between the untreated group and the treatment duration ≤1 year group （P<0.05）； there was a significant difference in the distribution of HBV RNA and HBV DNA levels between the untreated group and the treatment duration >1 year group （P<0.05）； there was a significant difference in the distribution of HBV RNA， HBV DNA， and HBsAg levels between the treatment duration ≤1 year group and the treatment duration >1 year group （P<0.05）. The correlation analysis between the duration of antiviral therapy and the levels of HBV RNA， HBV DNA， and HBsAg showed that the duration of antiviral therapy had an extremely weak negative correlation with the levels of HBV RNA and HBsAg （r=-0.247 and -0.138， both P<0.05） and a strong negative correlation with the level of HBV DNA （r=-0.771， P<0.001）. There was a low degree of correlation between the serum level of HBV RNA and the serum levels of HBV DNA and HBsAg （r=0.360 and 0.442， both P<0.001）. Further stratified analysis showed that in the untreated group， there was a strong positive correlation between HBV RNA and HBV DNA （r=0.752， P<0.001） and a moderate positive correlation between HBV RNA and HBsAg （r=0.559， P<0.001）； in the treatment duration ≤1 year group， there was a low degree of positive correlation between HBV RNA and HBV DNA/HBsAg （r=0.396 and r=0.388， both P<0.001）； in the treatment duration >1 year group， there was a low degree of positive correlation between HBV RNA and HBsAg （r=0.352， P<0.001）. ConclusionSerum HBV RNA is negatively correlated with the duration of treatment with NAs， and the correlation of HBV RNA with HBV DNA and HBsAg gradually decreases with the increase in the duration of treatment. Therefore， it can be used as a supplementary indicator for monitoring the level of virologic response in CHB patients to a certain extent， with a relatively high accuracy in reflecting the level of viral replication in untreated patients.

Dynamic change and significance of Mindin protein in chronic hepatitis B treated with PEG-IFNα-2b / 临床肝胆病杂志

ObjectiveTo investigate the change and potential role of Mindin protein in the treatment of chronic hepatitis B （CHB） with PEG-IFNα-2b. MethodsA total of 29 CHB patients who received the treatment with PEG-IFNα-2b in The Second Affiliated Hospital of Xi’an Jiaotong University from January 2018 to December 2019 were enrolled， and according to their clinical outcome， they were divided into cured group with 17 patients and uncured group with 12 patients. Peripheral blood samples were collected from both groups at baseline， 12 weeks， and 24 weeks to measure blood routine indices， liver function parameters， hepatitis B markers， and Mindin protein. HBsAg， alanine aminotransferase （ALT）， aspartate aminotransferase （AST）， and Mindin protein at different time points were compared between the two groups. The independent-samples t test was used for comparison of normally distributed continuous data between two groups， and the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between two groups； a Spearman correlation analysis was used to investigate correlation； a multiple linear regression analysis was used to investigate the influence of HBsAg and ALT on the content of Mindin protein. ResultsThe analysis of baseline data showed that there were significant differences in the levels of HBsAg， HBeAb， albumin， and albumin/globulin ratio between the cured group and the uncured group （all P<0.05）. The cured group tended to have a gradual increase in the level of Mindin， and the level of Mindin at 24 weeks was significantly higher than that at baseline （P<0.05）. The cured group had a significantly higher level of Mindin protein than the uncured group at 24 weeks （P=0.019）. The cured group had a significantly lower level of HBsAg than the uncured group （P<0.05）， with a significant change from baseline to each time point within the cured group （P<0.05）. In addition， the levels of ALT and AST in the cured group tended to first increase and then decrease， and the expression levels at 12 weeks were significantly higher than those at baseline （P<0.05）. At 12 weeks， there was a strong linear correlation between Mindin protein levels and ALT in the untreated group （r=0.760 8， P<0.05）， and further multiple linear regression analysis also demonstrated a linear relationship between the two （b=1.571， P=0.019）. ConclusionThere is a significant difference in the level of Mindin protein between the cured group and the non-cured group after 24 weeks of PEG-IFNα-2b antiviral treatment， and therefore， detecting the dynamic changes of Mindin protein can better predict the treatment outcome of CHB， which provides a reference for clinical practice.

ObjectiveTo investigate the application value of liver/spleen CT value （CTL/S）， controlled attenuation parameter （CAP）， and magnetic resonance imaging-proton density fat fraction （MRI-PDFF） in chronic hepatitis B （CHB） patients with hepatic steatosis. MethodsA retrospective analysis was performed for the clinical data of 213 CHB patients who underwent liver CT， CAP， and MRI-PDFF examinations in Affiliated Hospital of Yan’an University from October 2018 to December 2022. According to MRI-PDFF， the 213 patients were divided into CHB group with 111 patients （MRI-PDFF<5%） and CHB+hepatic steatosis group with 102 patients （MRI-PDFF≥5%）， among whom there were 69 patients with mild hepatic steatosis and 33 patients with moderate to severe hepatic steatosis. The independent-samples t test was used for comparison of normally distributed continuous data between groups， and the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between groups. The Bland-Altman plot was used to evaluate the consistency in MRI-PDFF measurement between two physicians. The Spearman’s correlation coefficient was used to analyze the correlation between CTL/S and MRI-PDFF and between CAP and MRI-PDFF. The receiver operating characteristic （ROC） curve was plotted and the area under the ROC curve （AUC） was calculated to investigate the value of CTL/S and CAP in the diagnosis of different degrees of hepatic steatosis， and the DeLong test was used to compare the AUCs of the two radiological examinations. ResultsMRI-PDFF had relatively high repeatability and stability in CHB patients. There is a significant negative correlation between CTL/S and MRI-PDFF （r=-0.800， P<0.001） and a significant positive correlation between CAP and MRI-PDFF （r=0.692， P<0.001）. Both CTL/S and CAP had a relatively high accuracy in the diagnosis of hepatic steatosis in CHB patients， with an AUC of 0.951 and 0.902， respectively， and CTL/S had a better accuracy than CAP （P<0.05）. In the diagnosis of mild and moderate-to-severe hepatic steatosis， CTL/S had an AUC of 0.921 and 0.895， respectively， and CAP had an AUC of 0.859 and 0.825， respectively， suggesting that CTL/S had a slightly higher diagnostic efficiency than CAP. ConclusionMRI-PDFF has high repeatability and stability in CHB patients， and CTL/S and CAP have a high diagnostic value for different degrees of hepatic steatosis in CHB patients.

ObjectiveTo investigate the preventive and therapeutic effects of Tiaogan Huaxian pills combined with entecavir on hepatic fibrosis in chronic hepatitis B with liver Qi stagnation， spleen deficiency， and blood stasis syndrome and its effect on diffusion-weighted imaging （DWI）. MethodClinical data of 117 patients with liver disease who visited the Department of Hepatology at the First Affiliated Hospital of Guangxi University of Chinese Medicine from January 2021 to April 2022 were retrospectively analyzed. According to different treatment plans， they were divided into a control group （59 cases） and a treatment group （58 cases）. Both groups of patients received entecavir-based etiology treatment， and the treatment group added Tiaogan Huaxian pills on the basis of basic treatment. Both groups were treated for 24 weeks. Before and after treatment， the two groups were compared in terms of alanine aminotransferase （ALT）， advanced surgical technologies （AST）， total bilirubin （TBil）， hepatitis B virus （HBV）-DNA conversion rate， liver stiffness measurement （LSM）， four items of liver fibrosis （hyaluronidase， type Ⅲ pro-collagen， type Ⅳ collagen， and laminin）， the fibrosis index based on four factors （FIB-4）， the aspartate aminotransferase to platelet ratio index （APRI）， the apparent diffusion coefficient （ADC） value in magnetic resonance imaging （MRI）， and traditional Chinese medicine symptom scores， so as to analyze the efficacy of the two groups. ResultBefore treatment， there was no significant difference in ALT， AST， TBil， LSM， four items of liver fibrosis， FIB-4， APRI， HBV-DNA conversion rate， ADC value， and traditional Chinese medicine symptom scores between the two groups. After treatment， both groups of patients showed significant reductions in ALT， AST， TBil， LSM， hyaluronidase， type Ⅲ pro-collagen， type Ⅳ collagen， laminin， FIB-4， and APRI （P<0.05） and a significant increase in ADC value （P<0.05） and HBV-DNA conversion rate （P<0.01）. The traditional Chinese medicine symptom score of the treatment group decreased significantly （P<0.05）. Compared with the control group after treatment， the effective rate of clinical traditional Chinese medicine in the treatment group was 91.38% （53/58）， which was significantly higher than that of the control group （54.23%， 32/59） （Z=-4.325， P<0.01）. In the treatment group， ALT， AST， TBil， LSM， hyaluronidase， type Ⅲ pro-collagen， type Ⅳ collagen， laminin， FIB-4， APRI， and traditional Chinese medicine symptom scores all decreased significantly （P<0.05）， and the increase in ADC values was more significant （P<0.05）， while the difference in HBV-DNA conversion rate was not statistically significant. There were no serious adverse reactions or events in either group. ConclusionTiaogan Huaxian pills combined with entecavir have significant clinical efficacy in the treatment of hepatic fibrosis in chronic hepatitis B， which can reduce liver inflammation activity， delay hepatic fibrosis progression， and reduce traditional Chinese medicine symptom scores.

Screening and bioinformatics analysis of key autophagy-related genes in alcoholic hepatitis / 器官移植

Objective To screen key autophagy-related genes in alcoholic hepatitis (AH) and investigate potential biomarkers and therapeutic targets for AH. Methods Two AH gene chips in Gene Expression Omnibus (GEO) and autophagy-related data sets obtained from MSigDB and GeneCards databases were used, and the key genes were verified and obtained by weighted gene co-expression network analysis (WGCNA). The screened key genes were subject to gene ontology (GO), Kyoto Encyclopedia of Genes and Genomes (KEGG), protein-protein interaction (PPI) and immune infiltration analyses. Messenger RNA (mRNA)- microRNA (miRNA) network was constructed to analyze the expression differences of key autophagy-related genes during different stages of AH, which were further validated by real-time fluorescence quantitative polymerase chain reaction (RT-qPCR) in the liver tissues of AH patients and mice. Results Eleven autophagy-related genes were screened in AH (EEF1A2, CFTR, SOX4, TREM2, CTHRC1, HSPB8, TUBB3, PRKAA2, RNASE1, MTCL1 and HGF), all of which were up-regulated. In the liver tissues of AH patients and mice, the relative expression levels of SOX4, TREM2, HSPB8 and PRKAA2 in the AH group were higher than those in the control group. Conclusions SOX4, TREM2, HSPB8 and PRKAA2 may be potential biomarkers and therapeutic targets for AH.

Pathogenesis of hepatitis B-associated intrahepatic cholangiocarcinoma / 临床肝胆病杂志

Intrahepatic cholangiocarcinoma （ICC） is a type of primary liver cancer that accounts for about 10%‍ — ‍15% of the total cases， and its incidence and mortality rates tend to increase significantly around the world， especially in Asian countries. At present， radical liver resection is the only possible cure for ICC， but with a fairly high postoperative recurrence rate and a poorer prognosis than hepatocellular carcinoma. Therefore， it is urgently needed to further investigate the mechanisms of the development and progression of ICC and search for more effective treatment methods. Some epidemiological data suggest that chronic hepatitis B virus infection is one of the most important predisposing factors for ICC， yet little is known about its oncogenic effects.

Hepatitis C virus infection is a global public health issue， and the emergence of direct-acting antiviral agents has brought revolutionary breakthroughs in the treatment of hepatitis C patients. Although direct-acting antiviral agents have a marked therapeutic effect in adult patients， there are still many challenges in the treatment of special populations such as pregnant women， infants， young children， and adolescents. This article reviews the current status of antiviral therapy for these special populations with hepatitis C and the problems that need to be solved， in order to provide reference and guidance for clinical workers.

Current status of hepatitis C virus infection and progress in its elimination in China / 临床肝胆病杂志

Hepatitis C virus （HCV） can develop into liver cirrhosis or hepatocellular carcinoma， imposing a heavy burden on the patient’s family and the society. Hepatitis C is one of the major public threats for humans， and eliminating hepatitis C is a common goal of all humans. Direct-acting antiviral agents （DAAs） are currently a relatively safe treatment regimen for hepatitis C that can reach a relatively high cure rate and can target different HCV genotypes， making it possible to eliminate HCV infection. China actively promotes the clinical application of DAAs， accelerates drug approval， improves the accessibility of DAAs， and strengthens population intervention. National Medical Insurance Administration has gradually included DAAs in the national medical insurance directory， providing strong support for eliminating HCV infection. In response to the WHO’s goal of eliminating viral hepatitis as a public health hazard by 2030， China has successively released national strategic plans and action plans in recent years， making significant achievements in HCV infection elimination， forming a joint prevention and control system across multiple sectors of the society， and ultimately achieving the goal of eliminating HCV infection. With a focus on the current status of HCV infection in China and prominent prevention and control strategies， this article analyzes and summarizes the practical process of the prevention， control， and micro-elimination of HCV infection， in order to provide a policy reference for carrying out HCV elimination in China and help to achieve the goal of comprehensive elimination of HCV infection.

Renal injury caused by tenofovir disoproxil fumarate in a patient with liver cancer complicated with HBV infection：a case report and literature analysis / 中国药房

Tenofovir disoproxil fumarate （TDF） is a first-line treatment for chronic hepatitis B. With increasing use worldwide， the adverse events of renal injury caused by this drug have also attracted industry attention. This article reports a 61- year-old patient with liver cancer complicated with hepatitis B virus （HBV） infection. The patient started using TDF in mid-March 2022 and developed kidney injury after 2 months of treatment， during which he received 2 courses of donafenib combined with sintilimab chemotherapy and irregular administration of diclofenac for pain relief. In this paper， Naranjo’s assessment scale was used to evaluate the drugs that may be associated with renal injury， including TDF and sintilimab， and the drugs that are suspected to be associated with renal injury are donafenib and diclofenac. The renal injury caused by TDF can be judged according to the changes in the patient’s condition， the incidence of drug-induced renal injury， clinical manifestations， occurrence time， occurrence mechanism， drug combination， and high-risk factors. The changes of serum creatinine in patients with liver cancer complicated with HBV infection after TDF should be dynamically monitored in the clinic， and the dose of antiviral drugs should be adjusted if necessary and other antiviral drugs with less impact on renal function can be selected， to provide individualized medication recommendations for tumor patients， reduce the incidence of TDF-related renal injury.

Influencing factors for death within 30 days in patients with decompensated hepatitis B cirrhosis and hepatic encephalopathy / 临床肝胆病杂志

ObjectiveTo investigate the influencing factors for death within 30 days in patients with decompensated hepatitis B cirrhosis and hepatic encephalopathy. MethodsA retrospective analysis was performed for 616 patients with hepatitis B cirrhosis and hepatic encephalopathy in Beijing Ditan Hospital from January 2008 to April 2018， and all patients were followed up for 30 days. According to their prognosis， they were divided into survival group with 488 patients and death group with 128 patients. The Mann-Whitney U test was used for comparison of continuous data between two groups， and the chi-square test or the Fisher’s exact test was used for comparison of categorical data between two groups. The Cox regression analysis was used to investigate the independent risk factors for death within 30 days in patients with hepatitis B cirrhosis and hepatic encephalopathy. ResultsThe multivariate Cox regression analysis showed that age （hazard ratio ［HR］=1.029， 95% confidence interval ［CI］： 1.014‍ — ‍1.044， P<0.001）， Model for End-Stage Liver Disease （MELD） score （HR=1.118， 95%CI： 1.098‍ — ‍1.139， P<0.001）， and neutrophil-to-lymphocyte ratio （NLR） （HR=1.036， 95%CI： 1.015‍ — ‍1.057， P=0.001） were independent risk factors for death within 30 days in patients with hepatitis B cirrhosis and hepatic encephalopathy. The stratified analysis showed that the patients with a MELD score of≥20 and an NLR of≥4 had a higher risk of death， with a 30-day mortality rate of 57.1% （80/140）. The patients with a MELD score of<20 and an NLR of<4 had a 30-day mortality rate of 3.9% （9/232）. ConclusionAge， MELD score， and NLR are independent risk factors for death within 30 days in patients with hepatitis B cirrhosis and hepatic encephalopathy， and patients with a MELD score of≥20 and an NLR of≥4 tend to have a high risk of death.

Application value of two-dimensional shear wave elastography and serological models in the staging of liver fibrosis in patients with chronic hepatitis B / 临床肝胆病杂志

ObjectiveTo investigate the value of two-dimensional shear wave elastography （2D-SWE） or serological models used alone or in combination in determining the stage of liver fibrosis in patients with chronic hepatitis B. MethodsA retrospective analysis was performed for the clinical data of 327 patients with chronic hepatitis B who were admitted to Mengchao Hepatobiliary Hospital of Fujian Medical University from August 2020 to August 2022 and underwent 2D-SWE and liver histopathological examination， including sex， age， serological markers， and 2D-SWE results. According to the degree of liver fibrosis， they were divided into S0-S1， S≥2， S≥3， and S=4 groups， and the serological models were calculated based on serological markers. A Spearman correlation analysis was used to investigate the correlation of 2D-SWE and serological models with liver fibrosis stage； the receiver operating characteristic curve was plotted with the results of liver histopathology as the standard to compare the efficiency of each parameter used alone or in combination in determining the stage of liver fibrosis； the Delong test was used to investigate the difference between different methods. ResultsLiver stiffness measurement measured by 2D-SWE was strongly correlated with the stage of liver fibrosis （r=0.741， P<0.001）， and as for the serological model， six markers （APRI， FIB-4， GPR， GP， RPR， and S index）， other than AAR， were positively correlated with the stage of liver fibrosis （all P<0.001）. 2D-SWE had an area under the ROC curve （AUC） of 0.878， 0.932， and 0.942， respectively， in the diagnosis of S≥2， S≥3， and S=4 liver fibrosis （all P<0.001）， with an optimal cut-off value of 6.9 kPa， 7.9 kPa， and 9.4 kPa， respectively. Among the serological models， APRI had the largest AUC of 0.788 and 0.875， respectively， in the diagnosis of S≥2 and S=4 liver fibrosis， and S index had the largest AUC of 0.846 in the diagnosis of S≥3 liver fibrosis. In the diagnosis of S≥2， S≥3， and S=4 liver fibrosis， 2D-SWE combined with APRI increased the AUC values to 0.887， 0.938， and 0.950， respectively， and 2D-SWE combined with S index increased the AUC values to 0.879， 0.935， and 0.941， respectively， while there were no significant differences between 2D-SWE and the above combinations （P>0.05）. Conclusion2D-SWE has a better diagnostic efficacy than the above seven serological models in determining liver fibrosis stage. The serological models have a certain diagnostic value， among which APRI and S index have a relatively high diagnostic value. There is no significant difference between 2D-SWE and 2D-SWE combined with serological models， and such combinations cannot significantly improve diagnostic efficiency. Therefore， further studies are needed to explore new combinations of diagnostic methods.

Role and mechanism of action of Yinchenhao Decoction in inhibiting ferroptosis of hepatocytes in mice with autoimmune hepatitis / 临床肝胆病杂志

ObjectiveTo investigate the role and mechanism of action of Yinchenhao Decoction in inhibiting ferroptosis of hepatocytes in mice with autoimmune hepatitis. MethodsA total of 18 specific pathogen-free female C57BL/6 mice were selected and divided into normal group， model group， and treatment group using a random number table， with 6 mice in each group. The mice in the model group and the treatment group were injected with concanavalin A （Con A） via the caudal vein to establish a mouse model of autoimmune hepatitis， and those in the normal group were injected with normal saline. The mice in the treatment group were given prophylactic treatment with Yinchenhao Decoction （4.68 g crude drug/kg） by gavage at 14 days before modeling， and Con A was injected after the last gavage. The levels of alanine aminotransferase （ALT）， aspartate aminotransferase （AST）， interferon gamma （IFN-γ）， tumor necrosis factor-α （TNF-α）， iron ion， glutathione （GSH）， reactive oxygen species （ROS）， adenosine triphosphate （ATP）， and malondialdehyde （MDA） were measured； liver index and spleen index were calculated； the expression levels of GPX4 and SLC7A11 were measured； liver histopathological changes were compared between groups. A one-way analysis of variance was used for comparison of normally distributed continuous data between three groups， and the least significant difference t-test was used for further comparison between two groups. ResultsCompared with the normal group， the model group had significant increases in liver index， spleen index， ALT， AST， IFN-γ， TNF-α， iron ion， ROS and MDA （all P<0.05） and significant reductions in the content of GSH and ATP and the protein expression levels of GPX4 and SLC7A11 （all P<0.05）. Compared with the model group， the treatment group had significant reductions in liver index， spleen index， ALT， AST， IFN-γ， TNF-α， iron ion， ROS and MDA （all P<0.05） and significant increases in the content of GSH and ATP and the protein expression levels of GPX4 and SLC7A11 （all P<0.05）. HE staining showed that compared with the normal group， the model group showed massive hepatocyte degeneration and necrosis and inflammatory cell aggregation at the portal area， and compared with the model group， the treatment group had alleviation of liver necrosis and inflammatory infiltration. ConclusionLiver injury induced by Con A may be associated with ferroptosis. Yinchenhao Decoction can increase the protein expression levels of SLC7A11 and GPX4 protein and thus inhibit ferroptosis of hepatocytes induced by Con A.
