Abnormal liver biochemical parameters in pregnancy during the epidemic of coronavirus disease 2019 / 临床肝胆病杂志

ObjectiveTo investigate the differences in abnormal liver biochemical parameters in pregnant patients during the epidemic or non-epidemic period of coronavirus disease 2019 （COVID-19）. MethodsA retrospective analysis was performed for 539 pregnant women who were discharged from Department of Obstetrics， Peking University First Hospital， from October 2017 to March 2022 and had at least one abnormal liver biochemical parameter among alanine aminotransferase （ALT）， aspartate aminotransferase （AST）， gamma-glutamyl transpeptidase （GGT）， total bilirubin （TBil）， and total bile acid. The patients in the epidemic period of COVID-19 and those in the non-epidemic period of COVID-19 were compared in terms of etiology， coagulation parameters， aminotransferases， bile acid， and renal function. The independent samples t-test was used for comparison of continuous data between two groups， and the chi-square test was used for comparison of categorical data between two groups. ResultsAmong the patients discharged from Department of Obstetrics during the non-epidemic period of COVID-19， 262 had abnormal liver biochemical parameters， accounting for 1.46%， while 277 patients had abnormal liver biochemical parameters during the epidemic period of COVID-19， accounting for 1.73% among the patients discharged from Department of Obstetrics during the same period of time， and there was a significant difference between these two groups （χ2=3.947， P=0.047）. The etiological analysis of the patients with abnormal liver biochemical parameters during the two periods showed that there was no difference in the proportion of patients with four pregnancy-specific liver diseases （hyperemesis gravidarum， preeclampsia and eclampsia， intrahepatic cholestasis of pregnancy， and acute fatty liver of pregnancy）. As for the patients with abnormal liver biochemical parameters in pregnancy， there was no significant difference in the proportion of patients with normal creatinine and stimated glomerular filtration rate （eGFR） between the epidemic period and the non-epidemic period （86.78% vs 87.90%， χ2=0.141， P=0.708）. The patients with ALT≥5×upper limit of normal accounted for 7.94% in the epidemic period of COVID-19 and 9.54% in the non-epidemic period （χ2=0.433， P=0.511）， and the patients with severe cholestasis accounted for 7.75% in the epidemic period of COVID-19 and 9.27% in the non-epidemic period （χ2=0.392， P=0.531）. The proportion of patients with obstetric bleeding during the epidemic period of COVID-19 was significantly lower than that during the non-epidemic period （14.61% vs 24.19%， χ2=489.334， P<0.001）. ConclusionThere is no difference in the proportion of patients with pregnancy-specific liver diseases among the patients with abnormal liver biochemical parameters in pregnancy between the epidemic period and the non-epidemic period of COVID-19， and there is no change in the proportion of patients with normal creatinine and eGFR among these patients in the epidemic period of COVID-19.

Efficacy and safety of anti-PD-1 monoclonal antibody combined with sorafenib or lenvatinib in treatment of patients with Child-Pugh class B unresectable hepatocellular carcinoma / 临床肝胆病杂志

ObjectiveTo investigate the safety and efficacy of tyrosine kinase inhibitors combined with immune checkpoint inhibitors in the treatment of patients with Child-Pugh class B unresectable hepatocellular carcinoma （uHCC）. MethodsA total of 96 patients with Child-Pugh class B uHCC who were admitted to Beijing Ditan Hospital， Capital Medical University， from December 31， 2020 to March 30， 2023 were enrolled as subjects， among whom 63 patients receiving lenvatinib combined with programmed death-1 （PD-1） inhibitor were enrolled as L group and 33 patients receiving sorafenib combined with PD-1inhibitor were enrolled as S group. The primary endpoint was objective response rate （ORR）， and secondary endpoints included time to progression （TTP）， overall survival （OS）， toxicity， drug withdrawal rate， and dose adjustment rate. The 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. Survival curves were plotted， and the Kaplan-Meier method was used to calculate the survival rate of patients in both groups， while the Log-rank test was used for comparison between the two groups. The Cox regression model was used to calculate hazard ratio （HR） and its 95% confidence interval （CI） and perform the multivariate analysis of influencing factors for prognosis. ResultsAmong the 96 patients with uHCC， 55 （57.3%） had Child-Pugh class B （7 points） uHCC and 41 （42.7%） had Child-Pugh class B （8—9 points） uHCC. The L group had a significantly higher ORR than the S group （46.0% vs 15.2%， P=0.003）， and there were no significant differences between the L group and the S group in median TTP （6.6 months vs 3.5 months， P=0.48） or OS （13.8 months vs 13.2 months， P=0.95）. There was no significant difference in median TTP between the patients with Child-Pugh class B （7 points） uHCC and those with Child-Pugh class B （8—9 points） uHCC （6.6 months vs 4.8 months， P=0.35）， while there was a significant difference in OS between these two groups of patients （14.5 months vs 8.8 months， P=0.045）. The multivariate analysis showed that ORR was a protective factor for both TTP （HR=0.18， 95%CI： 0.09 ‍—‍ 0.36， P<0.001） and OS （HR=0.20， 95%CI： 0.09 ‍—‍ 0.43， P<0.001）. There were no significant differences between the L group and the S group in the overall incidence rate of adverse reactions （98.4% vs 97.0%） and the incidence rate of grade≥3 adverse reactions （68.3% vs 63.6%）， and there were also no significant differences between the two groups in dose adjustment rate （84.8% vs 70.2%） and drug withdrawal rate （56.1% vs 72.7%）. ConclusionCompared with the regimen of sorafenib combined with PD-1 inhibitor， the regimen of lenvatinib combined with PD-1 inhibitor can improve the ORR of patients with Child-Pugh class B uHCC， with similar prognosis and safety profile between the two groups.

Predictive value of continuous monitoring of indocyanine green retention rate at 15 minutes combined with standard residual liver volume for hepatic insufficiency in patients with hepatocellular carcinoma after partial hepatectomy / 临床肝胆病杂志

ObjectiveTo investigate the value of continuous monitoring of indocyanine green retention rate at 15 minutes （ICG-R15） combined with standard residual liver volume （SRLV） in predicting hepatic insufficiency after partial hepatectomy. MethodsClinical data and SRLV data were collected from 70 patients with hepatocellular carcinoma who were admitted to Department of Hepatobiliary Surgery， Tianjin First Central Hospital， from November 2016 to May 2017. According to the presence or absence of hepatic insufficiency after surgery， the patients were divided into good liver function group with 56 patients and hepatic insufficiency group with 14 patients. Based on preoperative liver function evaluation and contrast-enhanced CT scans， resected liver volume and residual liver volume were calculated， and three-dimensional reconstruction of the liver was performed. Intraoperative ultrasound localization was performed to determine the surgical regimen， and selective hepatic inflow occlusion or intermittent hepatic portal occlusion was selected based on intraoperative conditions. CUSA combined with BIPOLAR drip electric coagulation forceps were used for the partition of liver parenchyma. SRLV was calculated， and ICG-R15 was monitored continuously. The independent-samples t test was used for comparison of continuous data between two groups， and the chi-square test was used for comparison of categorical data between two groups； the area under the ROC curve （AUC） was used to investigate the accuracy in predicting hepatic insufficiency after surgery. A multivariate Logistic regression analysis was used to establish a predictive model for postoperative hepatic insufficiency， and diagnostic criteria were developed for SLRV combined with postoperative ICG-R15 dynamic monitoring in the diagnosis of postoperative hepatic insufficiency. ResultsThere were significant differences between the two groups in ICG-R15 before surgery， immediately after surgery， and on days 3 and 5 after surgery， as well as significant differences in SRLV and Child class （all P<0.05）. The incidence rate of postoperative hepatic insufficiency increased with the increase in ICG-R15 before surgery， immediately after surgery， and on days 3 and 5 after surgery （all P<0.001）. Further comparison between two groups showed that there was a significant difference in the incidence rate of hepatic insufficiency between the ICG-R15>20% group and the other two groups before surgery， immediately after surgery， and on days 3 and 5 after surgery （all P<0.001）， and there was a significant difference in the incidence rate of hepatic insufficiency between the ICG-R15<10% group and the 10%≤ICG-R15≤20% group immediately after surgery （P<0.001）. ICG-R15 before surgery， ICG-R15 immediately after surgery， ICG-R15 on day 3 after surgery， and ICG-R15 on day 5 after surgery had an AUC of 0.790， 0.857， 0.855， and 0.870， respectively， in predicting postoperative hepatic insufficiency， and ICG-R15 immediately after surgery and on days 3 and 5 after surgery had a significantly larger AUC than ICG-R15 before surgery （all P<0.05）. The multivariate analysis showed that increases in SRLV and postoperative ICG-R15 dynamic monitoring （immediately after surgery and on days 3 and 5 after surgery） were independent risk factors for postoperative hepatic insufficiency， while increased body mass index before surgery was an independent protective factor （all P<0.05）. A multivariate Logistic regression predictive model was established and was used to predict hepatic insufficiency after surgery （immediately after surgery and on days 3 and 5 after surgery）， and the ROC curve analysis showed that the model had an AUC of 0.963， 0.967， and 0.967， respectively， in predicting hepatic insufficiency immediately after surgery and on days 3 and 5 after surgery （all P<0.01）. Diagnostic criteria were developed for SLRV combined with postoperative ICG-R15 dynamic monitoring in the diagnosis of postoperative hepatic insufficiency， i.e.， SLRV>1 240 mL/m2， ICG-R15>20% immediately after surgery， or ICG-R15>25% on day 3 or 5 after surgery， and postoperative hepatic insufficiency could be diagnosed if a patient met any one criterion. These diagnostic criteria had a sensitivity of 100%， a specificity of 60.71%， and a conformity degree of 68.57%. ConclusionContinuous monitoring of ICG-R15 before and after surgery is of guiding significance for predicting postoperative hepatic insufficiency， and ICG-R15 on day 5 after surgery has the highest accuracy. SRLV combined with postoperative ICG-R15 dynamic monitoring can effectively predict the onset of hepatic insufficiency after hepatectomy and can guide clinicians to predict the onset of postoperative hepatic insufficiency in patients with liver cancer and perform clinical intervention as soon as possible.

Predictive value of ALBI score and PALBI score in assessing the risk of liver insufficiency or liver failure after hepatectomy / 肿瘤研究与临床

Objective:To explore the predictive value of preoperative albumin-bilirubin (ALBI) score and platelet-albumin-bilirubin (PALBI) score in evaluating the risk of post-hepatectomy liver dysfunction (PLD) or post-hepatectomy liver failure (PHLF) of primary hepatocellular carcinoma (HCC).Methods:The clinical data of 106 primary HCC patients who received partial liver resection in the First Hospital of Shanxi Medical University from April 2018 to January 2023 were retrospectively analyzed. According to the presence of PLD or PHLF complication or not based on 50-50 criteria, all recipients were divided into PLD or PHLF group and non-PLD or non-PHLF group. The differences of preoperative serological detection indexes were compared between the two groups. Multivariate logistic regression was used to analyze the influencing factors of PLD or PHLF in primary HCC patients. The 50-50 criteria was taken as the gold standard, and the receiver operating characteristic (ROC) curve was used to assess the efficacy of ALBI score and PALBI score in judging of PLD or PHLF of primary HCC patients.Results:Among the 106 HCC patients, 13 cases (12.26%) of them suffered PLD or PHLF, while 93 cases (87.74%) did not. The age of patients in PLD or PHLF group and non-PLD or non-PHLF group was (60±7) years, (58±10) years, respectively; and there were 10 cases (76.92%) males, 69 cases (74.19%) males, respectively in both groups. There were statistically significant differences in aspartate aminotransferase, γ glutamyl transpeptidase, total bilirubin, albumin, tumor diameter, Child-Pugh score, ALBI score and PALBI score before operation between the two groups (all P < 0.05). The results of multivariate regression analysis showed that Child-Pugh score ( HR = 2.250, 95% CI 1.097-4.615, P = 0.027), ALBI score ( HR = 10.374, 95% CI 2.767-38.890, P = 0.001) and PALBI score ( HR = 33.074, 95% CI 4.677-233.894, P < 0.001) were independent influencing factors of PLD or PHLF in primary HCC patients ( P < 0.05). ROC curve result showed that the area under the curve of Child-Pugh score for predicting PLD or PHLF in HCC patients was 0.647 (95% CI 0.548-0.738), the area under the curve of ALBI score was 0.791 (95% CI 0.701-0.864), and the area under the curve of PALBI score was 0.794 (95% CI 0.704-0.866). The optimal cut-off value of Child-Pugh score for predicting PLD or PHLF in primary HCC patients was 6.500, the sensitivity was 38.5%, and the specificity was 92.5%. The optimal cut-off value of ALBI score for predicting PLD or PHLF in primary HCC patients was -2.345, the sensitivity was 76.9%, and the specificity was 77.4%. The optimal cut-off value of PALBI score for predicting PLD or PHLF in primary HCC patients was -2.050, the sensitivity was 69.2%, and the specificity was 92.5%. Conclusions:Both PALBI score and ALBI score is better than Child-Pugh score in the predictive efficacy of PLD or PHLF for primary HCC patients after hepatectomy.

Clinical features of patients with severe acute respiratory syndrome coronavirus 2 Delta variant infection and abnormal liver function in Guangdong Province, China / 临床肝胆病杂志

Objective To investigate the clinical features of patients with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) Delta variant infection and abnormal liver function in Guangdong Province, China. Methods The patients with SARS-CoV-2 Delta variant infection who belonged to the same chain of transmission in Guangdong Province (Guangzhou and Foshan) and were admitted to Guangzhou Eighth People's Hospital, Guangzhou Medical University from May 21 to June 18, 2021 were enrolled in this study, and the judgment criteria for liver function were alanine aminotransferase (male/female) > 50/40 U/L, aspartate aminotransferase > 40 U/L, total bilirubin > 26 μmol/L, gamma-glutamyl transpeptidase > 60 U/L, and alkaline phosphatase (ALK) > 125 U/L. Abnormality in any one item of the above criteria was defined as abnormal liver function, and such patients were included in analysis (the patients, aged < 18 years, who had a mild or moderate increase in ALP alone were not included in analysis). Clinical data were compared between the patients with normal liver function and those with abnormal liver function, and the etiology and prognosis of abnormal liver function were analyzed. The Mann-Whitney U test was used for comparison of continuous data between two groups; the chi-square test was used for comparison of categorical data between two groups. Results Among the 166 patients with SARS-CoV-2 Delta variant infection, 32 (19.3%) had abnormal liver function with mild-to-moderate increases in liver function parameters, and compared with the normal liver function group, the abnormal liver function group had a significantly higher proportion of critical patients ( χ 2 =38.689, P < 0.001) and significantly higher age and inflammatory cytokines [C-reactive protein type, serum amyloid A, and interleukin-6 (IL-6)](all P < 0.05). Among the 32 patients with abnormal liver function, 13 patients had abnormal liver function on admission (defined as primary group), while 19 patients had normal liver function on admission but were found to have abnormal liver function by reexamination after treatment (defined as secondary group). For the primary group, the evidence of abnormal liver function was not found for 3 patients (3/13, 23.1%), and the possibility of toxic liver injury directly associated with SARS-CoV-2 infection was considered. Among the 19 patients in the secondary group, 9 (47.4%) had mild/common type and 10 (52.6%) had critical type, and all critical patients had the evidence of liver injury indirectly caused by the significant increases in C-reactive protein type, serum amyloid A, and IL-6 and hypoxemia; the evidence of abnormal liver function was not found for only 1 patient (1/19, 5.3%), and the possibility of toxic liver injury directly associated with SARS-CoV-2 infection was considered. All 32 patients with abnormal liver function had [JP2]significant reductions in liver function parameters after treatment including liver protection. Conclusion As for the patients with SARS-CoV-2 Delta variant infection who belong to the same chain of transmission in Guangdong Province, the critical patients show a significantly higher proportion of patients with abnormal liver function than the patients with other clinical types, and other factors except SARS-CoV-2 infection and indirect injury caused by SARS-CoV-2 infection are the main cause of liver injury.

Features of liver injury in adolescents and adults with infectious mononucleosis: A single-center retrospective clinical study of 274 cases / 临床肝胆病杂志

ObjectiveTo investigate the features of liver injury and related influencing factors in adolescents and adults with infectious mononucleosis (IM). MethodsA retrospective analysis was performed to investigate the features of liver injury in adolescents and adults with IM who were hospitalized in Peking University First Hospital from January 2005 to December 31 2018, and the patients were divided into subgroups based on age, Epstein-Barr virus (EBV) DNA level, and presence or absence of jaundice or infection with cytomegalovirus or hepatitis E virus (HEV). The t-test was used for comparison of continuous data meeting analytical conditions between two groups, and the Mann-Whitney U test was used for comparison of continuous data which did not meet analytical conditions between two groups; the chi-square test was used for comparison of categorical data between two groups, and the Fisher’s exact test was used for comparison of categorical data which did not meet the analytical conditions of the chi-square test. A logistic regression analysis was used for multivariate analysis. ResultsA total of 274 patients were enrolled, with 154 male patients (56.2%) and 120 female patients (43.8%), and the mean age of onset was 22.3±67 years. The incidence rate of liver injury ［defined as alanine aminotransferase (ALT) ＞50 U/L and/or aspartate aminotransferase (AST)＞40 U/L］ was 97.4% (267/274), and that of jaundice was 27.6% (74/268). The patients, aged ≥20 years, tended to have a higher level of gamma-glutamyl transpeptidase (GGT) (Z=2.070, P=0.038). Serum EBV DNA was measured for 167 patients, among whom 90 had positive results and 77 had negative results. The positive serum EBV DNA group had significantly higher levels of GGT (Z=3.005, P=0.003) and lactate dehydrogenase (Z=2.162, P=0.031) than the negative serum EBV DNA group. The patients with cytomegalovirus infection tended to have a higher level of alkaline phosphatase (Z=2.351, P=0.019), and the patients with HEV infection presented with a higher level of GGT (Z=1.988, P=0.047). AST (odds ratio ［OR］=1.006, 95% confidence interval ［CI］: 1.002-1.010, P=0.005) and ALP (OR=1.012, 95%CI: 1.005-1.020, P=0.001) were independent risk factors for jaundice. ConclusionThere is a high incidence rate of liver injury in adolescents and adults with IM, and the patients with an older age or positive serum EBV DNA tend to have more severe liver injury.

Efficacy of early versus delayed laparoscopic cholecystectomy in the treatment of acute calculous cholecystitis combined with abnormal liver function / 中国基层医药

Objective:To investigate the efficacy of early versus delayed laparoscopic cholecystectomy (LC) in the treatment of acute calculous cholecystitis complicated by abnormal liver function. Methods:A total of 106 patients with acute calculous cholecystitis complicated by abnormal liver function who received LC in Nanjing Drum Tower Hospital, Nanjing University Medical School, China between February 2018 and February 2020 were included in this study. They were assigned to receive laparoscopic cholecystectomy either within 72 hours after disease onset (early group, n = 51) or 72 hours after disease onset (delayed group, n = 51). Perioperative indexes, complications, immune function and liver function were compared between the two groups. Results:Intraoperative blood loss in the early group was less than that in the delayed group [(63.11 ± 8.18) mL vs. (92.39 ± 7.23) mL, t = 19.558, P < 0.001]. Operative time, time to anal exhaust and length of hospital stay in the early group were (49.53 ± 6.33) minutes, (23.24 ± 4.65) hours and (6.38 ± 1.23) days in the early group were significantly shorter than those in the delayed group [(63.24 ± 5.42) minutes, (32.88 ± 5.78) hours, (8.34 ± 1.54) days, t = 12.004, 9.415, 7.204, all P < 0.001]. There was no significant difference in the rate of conversion to open cholecystectomy during LC between the two groups ( χ2 = 0.877, P > 0.05). There was no significant difference in the incidence of complications between early and delayed groups [11.76% (6/51) vs. 7.27% (4/55), χ2 = 0.625, P > 0.05]. On day 3 after surgery, the proportion of CD 3+ cells and the ratio of CD 4+/CD 8+ cells in the early group were (37.81 ± 4.29) % and (1.32 ± 0.29), respectively, which were significantly higher than those in the delayed group [(32.56 ± 5.26) %, 1.21 ± 0.23, t = 5.605, 6.379, both P < 0.001]. Total bilirubin, alanine aminotransferase and alkaline phosphatase levels in the early group were (21.05 ± 5.16) μmol/L, (71.58 ± 9.36) U/L and (175.73 ± 19.64) U/L, respectively, which were significantly lower than those in the delayed group [(27.81 ± 5.14) μmol/L, (82.54 ± 12.35) U/L, (214.62 ± 20.58) U/L, t = 6.921, 7.893, 9.865, all P < 0.001]. On day 5 after surgery, total bilirubin, alanine aminotransferase and alkaline phosphatase levels in the early group were (14.63 ± 4.58) μmol/L, (42.13 ± 8.24) U/L, (137.72 ± 17.62) U/L, respectively, which were significantly lower than those in the delayed group [(18.67 ± 6.45) μmol/L, (59.64 ± 11.29) U/L, (162.76 ± 18.39) U/L, t = 3.692, 8.265, 7.462, all P < 0.001]. Conclusion:Early LC for treatment of acute calculous cholecystitis complicated by abnormal liver function can effectively promote the recovery of liver function, mitigate immune injury, improve perioperative indicators, and dose not increase the incidence of complications.

Chanarin-Dorfman syndrome: the first case reported in China / 中华皮肤科杂志

Objective:To detect gene mutations and make a diagnosis in a family with ichthyosis accompanied by liver injury.Methods:Clinical data were collected from the proband, and genomic DNA was extracted from peripheral blood samples from the proband and his parents. Exome sequencing was performed in the proband by using a gene panel targeting hereditary skin diseases to identify mutation sites, and then the candidate mutation site was verified by PCR and Sanger sequencing in the family members. Results of peripheral blood smear examination and other auxiliary examinations were collected from the proband and his parents and analyzed.Results:The proband presented with generalized dry skin and tiny white scales on the lower limbs, accompanied by elevated transaminase levels, mild sensorineural hearing loss in both ears and fatty liver. Exome sequencing revealed a homozygous mutation c.933dupA in exon 6 of the ABHD5 gene encoding CGI-58 protein in the peripheral blood genomic DNA of the proband, resulting in a frameshift mutation p.R312Tfs*45 in the amino acid sequence. Heterozygous mutations at this site were identified in his father and mother. The mutation cosegregated with the disease phenotype in the family. The peripheral blood smear examination of the proband showed lipid vacuoles in neutrophils, which were called Jordan anomaly. Conclusion:The diagnosis of Chanarin-Dorfman syndrome was made in the proband based on the presentation of ichthyosis-like skin lesions and abnormal liver function, as well as the homozygous mutation in the ABHD5 gene and Jordan anomaly in peripheral blood smears.

Value of Fractalkine and soluble CD40 ligand in bile in predicting liver injury after liver transplantation / 临床肝胆病杂志

Objective To investigate the value of cytokines in bile combined with clinical indices in predicting the degree of liver injury after liver transplantation. MethodsA total of 16 patients undergoing liver transplantation who were hospitalized in Center of Organ Transplantation, The Affiliated Hospital of Qingdao University, from January to December 2018 were enrolled, and according to the level of alanine aminotransferase (ALT) on day 1 after surgery, the patients were divided into mild liver injury (ALT ＜500 U/L) group with 10 patients and severe liver injury (ALT ＞500 U/L) group with 6 patients. Bile samples were collected on days 1, 3, 5, and 7 after surgery, and MILLIPLEX assay was used to measure the levels of 17 cytokines. R software was used to perform principal component analysis (PCA) of bile cytokines and clinical indices and gene ontology (GO) enrichment analysis of bile cytokines. The two-independent-samples t-test was used for comparison of normally distributed continuous data between two groups; The Mann-Whitney U test was used for comparison of non-normally distributed continuous data between two groups. A Spearman correlation analysis was performed to evaluate the correlation between clinical indices and bile cytokines. ROC curve analysis was used to evaluate the predictive value of cytokines in bile and clinical indices for liver injury after liver transplantation. ResultsCompared with the mild liver injury group, the severe liver injury group had significantly higher expression levels of bile Fractalkine (Z=-2.828, P=0.003), soluble CD40 ligand (sCD40L) (Z=-2.850, P=0.008), interleukin-4 (Z=-2.398, P=0.017), CXCL10 (Z=-2.475, P=0.023), and macrophage inflammatory protein-1α (Z=-1844, P=0.043). The correlation analysis showed that on day 1 after liver transplantation, aspartate aminotransferase, ALT, and lactate dehydrogenase were positively correlated with the levels of several cytokines in bile (all P＜0.05). The area under the ROC curve of Fractalkine, sCD40L and AST were 0.933 (0.812-1.000), 0.833 (0.589-1.000) and 0.917 (0.779-1.000), respectively, suggesting that AST and Fractalkine and sCD40L in bile on the first day after liver transplantation have significant predictive value for liver injury. The results of PCA showed that bile cytokines combined with clinical indices on day 1 after liver transplantation could better distinguish the patients with mild liver injury from those with severe liver injury. GO analysis showed that bile cytokines were associated with positive feedback regulation of external stimulus, cell chemotaxis, receptor ligand activity, cytokine activity, and cytokine-cytokine receptor interaction. ConclusionFractalkine and sCD40L in bile can predict the degree of liver injury after liver transplantation.

Gd-BOPTA-enhanced MRI evaluation of liver function in patients with cirrhosis / 中国医学影像技术

Objective: To investigate the relationship between liver function parameters and liver parenchymal relative enhancement (RE) at hepatocyte phase with gadobenate dimeglumine (Gd-BOPTA)-enhanced MRI, and to clarify clinical predictive factors affecting liver parenchymal RE.Methods: Data of 238 patients underwent abdominal Gd-BOPTA-enhanced MRI were retrospectively analyzed and classified into 4 groups, i.e. normal liver function group (NLF group) and liver cirrhosis Child-Pugh A, B and C group (LCA, LCB and LCC groups). Liver parenchymal RE at hepatocyte phase was calculated, and the relationship between liver parenchyma RE and liver function parameters were analyzed, then clarified clinical predictive factors affecting liver parenchymal RE. Results: Liver parenchyma RE of hepatocyte phase were negatively correlated with the changes of total bilirubin (TB), prothrombin time (PT), international normalized ratio (INR), alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP) and Child-Pugh classification (all P<0.01),but positively correlated with albumin (Alb) and cholinesterase (ChE) (both P<0.01). Liver parenchyma RE at hepatocyte phase in NLF group were significantly higher than that in LCA,LCB and LCC groups (all P<0.001), respectively, and lower in patients with ascites than in those without ascites (P<0.001). Compared with LCB and LCC groups, liver parenchyma RE at hepatocyte phase in LCA group were significantly higher (both P<0.001), and predicted factors of liver parenchymal RE in hepatocyte stage included TB, Alb, ALP, and presence of ascites. Conclusion: There are significant correlations of liver parenchyma RE and liver functional parameters in liver cirrhosis, predictive factors of liver parenchymal RE in hepatocyte stage with Gd-BOPTA-enhanced MRI include TB, Alb, ALP and presence of ascites.

Association of blood lipids and albumin-bilirubin index with disease progression in patients with chronic hepatitis B virus infection / 临床肝胆病杂志

ObjectiveTo investigate the value of blood lipid indices and albumin-bilirubin index (ALBI) in evaluating the progression of chronic hepatitis B virus (HBV) infection. MethodsA total of 184 patients with chronic HBV infection who visited The Second Affiliated Hospital of Anhui Medical University from June 2016 to June 2017 were enrolled, and according to the stage of the disease, they were divided into ASC group (74 HBV carriers), CHB group (70 patients with chronic hepatitis B), and LC group (40 patients with compensated cirrhosis). A total of 50 healthy individuals were enrolled as health control (HC) group. Blood lipid indices and liver function parameters were measured, and the changes in blood lipid indices and ALBI during the progression of chronic HBV infection were analyzed. A one-way analysis of variance was used for comparison of continuous data between multiple groups, and the Dunnett method was used for further comparison between two groups; the chi-square test was used for comparison of categorical data between groups; Pearson correlation analysis was used to investigate correlation. Results There were significant differences between the ASC, CHB, LC, and HC groups in blood lipid indices of cholesterol (CHO), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), apolipoprotein A (APOA), and apolipoprotein B (F=12.075, 19.559, 6.554, 9.392, and 5.458, all P＜0.001), and the LC group had significantly greater reductions in the above indices compared with the other three groups (all P＜0.05). There was a significant difference in ALBI between the four groups (F=49.225, P＜0.001); the LC group had a significantly higher ALBI than the other three groups (all P＜005), and the ASC and CHB groups had a significantly higher ALBI than the HC group (both P＜0.05). CHO, HDL-C, LDL-C, and APOA were negatively correlated with ALBI (all P＜0.05), among which CHO and HDL-C had the strongest correlation with ALBI (r=-0.310 and -0.266, both P＜0.001). ConclusionIn patients with chronic HBV infection, blood lipid indices and ALBI can reflect the degree of liver function damage, especially in patients with liver cirrhosis.
