Objective:To explore the risk factors of short-term prognosis of severe Budd-Chiari syndrome (BCS) patients,established and verified the nomogram prediction model for these BCS patients and evaluated its clinical application value.Methods:This study is a retrospective cohort study. The clinical data of 171 patients with severe BCS diagnosed were retrospectively analyzed in the Department of Hepatopancreatobiliary Surgery First Affiliated Hospital of Zhengzhou University from January 2018 to December 2023. There were 105 males and 66 females, aged (52.1±12.8) years (range: 18 to 79 years). The patients were divided into two groups based on whether they died within 28 days: the death group ( n=38) and the survival group ( n=133). The risk factors for short-term death of patients were analyzed,and independent risk factors were screened by univariate and multivariate analysis. Furthermore,these factors were used to establish the nomogram prediction model. The area under the curve(AUC),the Bootstrap Resampling,the Hosmer-Lemeshow test and the Decision Curve Analysis(DCA) were used to verify the model′s differentiation,internal verification,calibration degree and clinical effectiveness,respectively. Results:Univariate and multivariate Logistics regression analysis showed that the history of hepatic encephalopathy,white blood cell,glomerular filtration rate and prothrombin time were independent risk factors ( P<0.05). The above factors were used to successfully establish the prediction model with 0.908 of AUC and 0.895 of the internal verification of AUC,indicating that the predictive model was valuable. The 0.663 P-values in the Hosmer-Lemeshow test indicated the high calibration degree of the model. The clinical effectiveness of the model was proved by the 18% clinical benefit population using the DCA curve with the 17% probability threshold. Conclusions:The independent risk factors are the history of hepatic encephalopathy,white blood cell,glomerular filtration rate and prothrombin time. An adequate basis was acquired by establishing a nomogram prediction model of the short-term prognosis of severe BCS,which was helpful for early clinical screening and identification of high-risk patients with severe BCS who could die in the short term and timely providing timely intervention measures for improving the prognosis.

Objective:To study the clinical value of the Naples prognostic score (NPS) in predicting the prognosis of patients with intrahepatic cholangiocarcinoma (ICC) after radical resection and establish a nomogram prediction model.Methods:Clinical data of 77 patients with ICC undergoing radical hepatectomy for the first time in the First Affiliated Hospital of Zhengzhou University from January 2018 to December 2022 were retrospectively collected, including 46 males and 31 females, aged (58.9±11.0) years old. The area under the receiver operating characteristic curve for NPS to predict the death after radical hepatectomy in ICC patients was 0.673, and the optimal cut-off value for NPS based on the Youden's index was 2.5. According to the optimal cut-off value of NPS, patients were divided into two groups: the low NPS group (patients with NPS≤2.5, n=37) and high NPS group (patients with NPS>2.5, n=40). The clinicopathological data including resection extent, blood transfusion, tumor differentiation, lymphovascular invasion, lymph node metastasis and postoperative complications were compared between the groups. Follow-ups were conducted via outpatient or telephone reviews. Kaplan-Meier method was used for survival analysis, and log-rank test was used for survival comparison. Cox proportional hazards regression was used to analyze the risk factors affecting postoperative survival. A prediction nomogram was established and evaluated. Results:Compared to the low NPS group, the proportion of patients with tumor length ≥5 cm, lymphovascular invasion, lymph node metastasis, tumor carbohydrate antigen 19-9 ≥37 U/ml and the level of neutrophil to lymphocyte ratio were increased in the high NPS group, while the proportion of patients with serum albumin ≥40 g/L was decreased (all P<0.05). The cumulative survival rate of patients in the high NPS group was lower than that of the low NPS group ( P=0.001). Multivariate Cox analysis showed that ICC patients with lymphovascular invasion, lymph node metastasis, and NPS>2.5 had a higher risk of short survival after surgery (all P<0.05). The nomogram model based on NPS has a good predictive capacity. Conclusion:High preoperative NPS score indicates poor postoperative prognosis, and NPS score is an independent risk factor affecting the prognosis of ICC patients.

Biliary tract malignancies is a malignancy with insidious onset, low surgical resection rate, poor prognosis and unsatisfactory chemotherapy effects. With the continuous in-depth study, combined immunotherapy based on immune checkpoint inhibitors (ICIs) has gradually become an important direction for the treatment of biliary tract malignancies. Several clinical trials have conducted in-depth exploration of ICIs alone and in combination with first-line chemotherapy regimens or targeted drugs or double immunization regimens for biliary malignant tumors. The results show that ICIs monotherapy exhibits certain efficacy, albeit with significant variations in treatment outcomes. The combination of ICIs with first-line chemotherapy has now become the standard treatment protocol. Furthermore, the " triple-drug and quadruple-therapy regimen" involving ICIs in conjunction with chemotherapy and molecular targeted therapy holds promise as a potential new standard for BTC treatment. Additionally, dual immunotherapy combinations are gradually being implemented in clinical trials. In the present article, we provides an in-depth elaboration of the current status of clinical research on immune checkpoint inhibitors and their combination therapy in advanced biliary tract malignancies.

Objective:To investigate the current status of endoscopic treatment for gastroesophageal varices in portal hypertension in China, and to provide supporting data and reference for the development of endoscopic treatment.Methods:In this study, initiated by the Liver Health Consortium in China (CHESS), a questionnaire was designed and distributed online to investigate the basic condition of endoscopic treatment for gastroesophageal varices in portal hypertension in 2022 in China. Questions included annual number and indication of endoscopic procedures, adherence to guideline for preventing esophagogastric variceal bleeding (EGVB), management and timing of emergent EGVB, management of gastric and isolated varices, and improvement of endoscopic treatment. Proportions of hospitals concerning therapeutic choices to all participant hospitals were calculated. Guideline adherence between secondary and tertiary hospitals were compared by using Chi-square test.Results:A total of 836 hospitals from 31 provinces (anotomous regions and municipalities) participated in the survey. According to the survey, the control of acute EGVB (49.3%, 412/836) and the prevention of recurrent bleeding (38.3%, 320/836) were major indications of endoscopic treatment. For primary [non-selective β-blocker (NSBB) or endoscopic therapies] and secondary prophylaxis (NSBB and endoscopic therapies) of EGVB, adherence to domestic guideline was 72.5% (606/836) and 39.2% (328/836), respectively. There were significant differences in the adherence between secondary and tertiary hospitals in primary prophylaxis of EGVB [71.0% (495/697) VS 79.9% (111/139), χ2=4.11, P=0.033] and secondary prophylaxis of EGVB [41.6% (290/697) VS 27.3% (38/139), χ2=9.31, P=0.002]. A total of 78.2% (654/836) hospitals preferred endoscopic therapies treating acute EGVB, and endoscopic therapy was more likely to be the first choice for treating acute EGVB in tertiary hospitals (82.6%, 576/697) than secondary hospitals [56.1% (78/139), χ2=46.33, P<0.001]. The optimal timing was usually within 12 hours (48.5%, 317/654) and 12-24 hours (36.9%, 241/654) after the bleeding. Regarding the management of gastroesophageal varices type 2 and isolated gastric varices type 1, most hospitals used cyanoacrylate injection in combination with sclerotherapy [48.2% (403/836) and 29.9% (250/836), respectively], but substantial proportions of hospitals preferred clip-assisted therapies [12.4% (104/836) and 26.4% (221/836), respectively]. Improving the skills of endoscopic doctors (84.2%, 704/836), and enhancing the precision of pre-procedure evaluation and quality of multidisciplinary team (78.9%, 660/836) were considered urgent needs in the development of endoscopic treatment. Conclusion:A variety of endoscopic treatments for gastroesophageal varices in portal hypertension are implemented nationwide. Participant hospitals are active to perform emergent endoscopy for acute EGVB, but are inadequate in following recommendations regarding primary and secondary prophylaxis of EGVB. Moreover, the selection of endoscopic procedures for gastric varices differs greatly among hospitals.

Objective:To investigate the predictive value of controlled nutritional status (CONUT) score for overt hepatic encephalopathy (OHE) after transjugular intrahepatic portosys-temic stent-shunt (TIPSS) in Budd-Chiari syndrome patients.Method:The retrospective case-control study was conducted. The clinicopathological data of 48 Budd-Chiari syndrome patients who underwent TIPSS in the First Affiliated Hospital of Zhengzhou University from August 2014 to March 2021 were collected. There were 26 males and 22 females, aged (46±13)years. Observation indicators: (1) surgical situations and follow-up; (2) analysis of influencing factors of OHE after TIPSS; (3) predic-tion of OHE after TIPSS. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was performed using the t test. Measurement data with skewed distribution were represented by M( Q1, Q3), and comparison between groups was performed using the Mann-Whitney U test. Count data were expressed as absolute numbers or percentages, and comparison between groups was performed using the chi-square test or Fisher exact probability. Multivariate analysis was performed using the Logistic regression model with forward method. The receiver operating characteristic (ROC) curve was drawn and the area under the curve (AUC) was calculated to evaluate the efficacy. Comparison among AUC was performed using the Delong test. Results:(1) Surgical situations and follow-up. All 48 patients underwent TIPSS successfully, and the operation time of the 48 patients was (131±29)minutes. All patients were implanted with 8 mm covered stent. All 48 patients were followed up for 46(25,71)months, and there were 14 cases with OHE and 34 cases without OHE after TIPSS. Of the 14 cases with OHE, 12 cases were evaluated as West-Haven Ⅱ grade and 2 cases were evaluated as West-Haven Ⅲ grade. (2) Analysis of influencing factors of OHE after TIPSS. Results of multivariate analysis showed that history of hepatic encephalo-pathy and CONUT score were independent factors influencing the incidence of OHE of Budd-Chiari syndrome patients who underwent TIPSS ( odds ratio=8.36, 1.74, 95% confidence interval as 1.02?68.75, 1.12?2.69, P<0.05). (3) Prediction of OHE after TIPSS. Results of ROC curve showed that the AUC of the CONUT score, the Child-Pugh score of liver function and the integrated model of end-stage liver disease (iMELD) score in predicting the incidence of OHE after TIPSS was 0.77(95% confidence interval as 0.64?0.91, P<0.05), 0.71(95% confidence interval as 0.56?0.87, P<0.05) and 0.71(95% confidence interval as 0.53?0.88, P<0.05), respectively, and there was no significant difference between the AUC of the CONUT score and the Child-Pugh score of liver function or the iMELD score ( Z=0.84, 0.59, P>0.05). The optimal cutoff value of CONUT score in predicting the incidence of OHE after TIPSS was 7, with the sensitivity, specificity and Yodon index as 78.6%, 61.8% and 0.40, respectively. Conclusion:The CONUT score can be used to predict the incidence of OHE in Budd-Chiari syndrome patients who underwent TIPSS, and the discrimination of CONUT score is equivalent to the Child-Pugh score of liver function and the iMELD score.

Objective:To investigate the diagnosis and treatment strategies as well as prognostic factors of Budd-Chiari syndrome(B-CS)patients complicated with liver cirrhosis and hepatocellular carcinoma(HCC). Methods:Clinical data of 42 B-CS patients complicated with HCC admitted to Department of Hepatopancreatobiliary Surgery,the First Affiliated Hospital of Zhengzhou University from January 2014 to December 2020 were retrospectively analyzed,and the association between the clinical characteristics of patients and whether they had undergone B-CS treatment or not before HCC diagnosis was analyzed.Kaplan-Meier method was used to plot the survival curve of the patients.COX regression model was used to analyze the risk factors affecting the prognosis of B-CS patients complicated with HCC. Results:All 42 B-CS patients complicated with HCC had liver cirrhosis,their median survival time was 28 months,and the 1-,3-and 5-year survival rates were 76.2％,50.0％and 42.9％,respectively.The maximum tumor diameter,multiple tumor ratio and total bilirubin level in patients who had not received B-CS treatment before HCC diagnosis were higher than those in patients who had.Serum albumin level(hazard ratio:0.866,95％confidence interval:0.771-0.972,P=0.015)and not receiving B-CS treatment before HCC diagnosis(hazard ratio:2.796,95％confidence interval:1.020-7.666,P=0.046)were independent risk factors for the prognosis of B-CS patients complicated with HCC. Conclusion:The prognosis of B-CS patients complicated with HCC is relatively good.Serum albumin level and not receiving B-CS treatment before HCC diagnosis are independent risk factors for the prognosis of B-CS patients complicated with HCC.

Objective:To investigate the clinical treatment options for cavernous transformation of portal vein (CTPV).Methods:Data of 65 CTPV patients receiving invasive treatment and followed up at the First Affiliated Hospital of Zhengzhou University between Apr 2011 and Apr 2021 were collected. Patients were divided into four groups based on different treatment option, 24 patients were treated with transjugular intrahepatic portosystemic stent-shunt (TIPS) and 11 patients with splenopneumopexy, while 22 patients underwent splenectomy and devascularization , 8 were treated by endoscopic variceal ligation . The difference of postoperative upper gastrointestinal bleeding and hepatic encephalopathy between the four groups were analyzed,Results:There were no difference between four groups in sex, age, preoperative serum aspartate aminotransferase, total bilirubin, albuminand Child-Turcotte-Pugh grade. The incidence of hepatic encephalopathy in the TIPS group was 33.3%±9.6%、46.5%±10.3% and 64.4%±13.1% in half year, 1 year, and 3 years , respectively. Postoperative hepatic encephalopathy rate was higher in TIPS group( χ2=31.191, P=0.000). Three patients in the TIPS group developed upper gastrointestinal hemorrhage within 6 months after the operation, and postoperative upper gastrointestinal bleeding rate was higher in splenopneumopexy group( χ2=7.542, P=0.006), Conclusion:The clinical treatment options for CTPV patients are complicated ,we should make individual treatment options depend on the etiology, clinical symptoms and site of blood flow obstruction.

Objective To investigate the effect of metformin on liver fibrosis in a mouse model of Budd-Chiari syndrome and its mechanism. Methods A total of 30 male C57 mice were randomly divided into sham-operation group (SHAM group) with 6 mice, sham operation+ metformin group (SHAM+M group) with 5 mice, Budd-Chiari model group (BCS group) with 10 mice, and Budd-Chiari model+metformin group (BCS+M group) with 9 mice. The mice in the model group were treated with partial ligation of the inferior vena cava, those in the SHAM group were not treated with ligation, and those in the metformin group were given 0.1% metformin in drinking water besides modeling. The mice were sacrificed after 6 weeks. HE staining and picrosirius red staining were used to observe liver histopathology and collagen deposition; immunohistochemistry was used to measure the expressions of α-smooth muscle actin (α-SMA) and fibrinogen; quantitative real-time PCR was used to measure the mRNA expression of hypoxia-inducible factor 1α (HIF-1α) and type Ⅰ collagen (collagen 1), and Western blot was used to measure the relative protein expression levels of HIF-1α, vascular endothelial growth factor (VEGF), fibrinogen, α-SMA, and collagen 1. 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. Results Pathological staining showed that compared with the SHAM group, the BCS group had significant liver fibrosis, disordered arrangement of hepatocytes near the central vein, sinusoidal expansion with red blood cell deposition and a small amount of inflammatory cell infiltration, and collagen deposition. The BCS group had significant increases in the mRNA expression levels of HIF-1α and collagen 1 and the protein expression levels of α-SMA, collagen 1, HIF-1α, VEGF, and fibrinogen (all P < 0.05); compared with the BCS group, the BCS+M group had significant alleviation of liver fibrosis, red blood cell deposition, and collagen deposition and significant reductions in the mRNA expression levels of HIF-1α and collagen 1 and the protein expression levels of α-SMA, collagen 1, HIF-1α, VEGF, and fibrinogen (all P < 0.05). Conclusion Metformin can improve congestive liver fibrosis caused by Budd-Chiari syndrome, possibly by reducing microthrombus in hepatic sinusoid and inhibiting the HIF-1α/VEGF pathway.

Objective:To study the factors influencing short-term prognosis of patients with Budd-Chiari syndrome (B-CS) presenting with upper gastrointestinal bleeding and to assess the predictive value of platelet-albumin-bilirubin score (PALBI) on death within 30 d in these patients.Methods:A retrospective study was conducted on 74 patients with B-CS who presented with upper gastrointestinal bleeding and were treated at the First Affiliated Hospital of Zhengzhou University from January 2014 to February 2020. There were 51 males and 23 females, with age of (46.5±11.1) years old. These patients were divided into the survival group ( n=58) and the death group ( n=16) according to the disease outcomes up to 30 d of follow-up. Factors influencing short-term deaths of these patients were analyzed, and the predictive values of PALBI, ALBI, CTP and MELD scores on short-term prognosis of the patients were assessed. The receiver operating characteristic (ROC) curves were plotted, and the areas under the curve (AUC) were calculated and compared. Results:The differences between patients in the survival and death groups for white blood cell, platelet, PALBI score, PALBI classification, ALBI score, CTP score, MELD score, and presence or absence of hepatic encephalopathy were significantly different (all P<0.05). Multivariate logistic regression analysis showed that CTP score≥10 or CTP grade C ( OR=1.669, 95% CI: 1.048-2.661), and PALBI score >-2.09 or PALBI grade 3 ( OR=5.245, 95% CI: 2.128-12.924) were independent risk factors for predicting death within 30 days. The areas under the ROC curves for PALBI, ALBI, CTP and MELD score were 0.89, 0.72, 0.77 and 0.76, with the cut-off values of -1.92, -1.60, 8.50 and 13.60, respectively. The differences between the PALBI score and ALBI, CTP scores were significantly different ( P<0.05). Conclusion:The PALBI score showed a positive predictive value on short-term prognostic assessment of patients with B-CS presenting with upper gastrointestinal bleeding. It was comparable to the effect of the MELD score but was significantly better than the ALBI and CTP scores.
