ObjectiveTo systematically and objectively characterize the pharmacological effects of Fufang Biejia Ruangan pills （FBRP） in the intervention of alcoholic liver disease （ALD） using acute and chronic ALD mouse models and to elucidate its molecular mechanisms. MethodFifty SPF-grade male BALB/c mice were randomly divided into the normal group， model group， and FBRP low-， medium-， and high-dose groups （9.6， 19.2， 38.4 mg·kg^-1）. Except for the normal group， the remaining groups were given 56° white wine by gavage to establish the acute ALD model， with samples collected after 4 weeks. Thirty SPF-grade male C57BL/6N mice were randomly divided into the normal group， model group， and FBRP medium-dose group （19.2 mg·kg^-1）. The chronic ALD mouse model was established using the Lieber-DeCarli method over a 10-week period. Inflammatory markers in liver tissues were assessed using hematoxylin-eosin （HE）， Sirius Red， oil red O staining， and enzyme-linked immunosorbent assay （ELISA）. Intoxication behaviors of each group were objectively evaluated through sobering-up time， net-catching， and pole-climbing tests. Further bioinformatics analyses based on clinical transcriptomic data were conducted to identify key targets and molecular mechanisms of FBRP in alleviating ALD through liver-brain dialogue， with experimental validation by ELISA， Western blot， and immunohistochemical staining. ResultCompared with the normal group, the levels of aspartate aminotransferase （AST） and alanine aminotransferase （ALT） in liver tissues of mice in the acute and chronic ALD model groups were significantly increased （P<0.05）. Compared with the model group， the levels of AST and ALT in liver tissue of mice in FBRP groups were significantly decreased （P<0.05）. Compared with the normal group， the time of grasping the net and climbing the pole in the acute ALD model group was significantly decreased within 4 weeks （P<0.01）. Compared with the model group， the grasping and climbing time of FBRP high dose groups increased significantly within 4 weeks （P<0.05）. Compared with the normal group， the expression of high mobility group protein B1 （HMGB1） protein in liver tissue and prefrontal lobe tissue of mice in the chronic ALD model group was significantly increased （P<0.01）. Compared with the model group， the expression of HMGB1 protein in FBRP medium dose group was significantly decreased （P<0.05，P<0.01）. Compared with the normal group， the expression of brain-derived neurotrophic factor （BDNF） protein and the release of γ-aminobutyric acid （GABA） in the prefrontal cortex of the model group were significantly decreased （P<0.01）. Compared with the model group, the expression of BDNF protein and the release of GABA in the FBRP medium dose group were significantly increased （P<0.05）. ConclusionThis study revealed that FBRP improved key pathological changes in ALD by modulating liver-brain dialogue mediated by the HMGB1-BDNF axis. These findings provide experimental evidence for the clinical use of FBRP in treating ALD and offer new insights for the development of ALD therapeutic agents.

ObjectiveTo identify the pharmacodynamic material basis of Ruyi Zhenbaowan in relieving neuropathic pain by integrating the calculation of biological network proximity and pharmacokinetic characterization. MethodThe interaction network of "drug candidate target-related gene of disease" was constructed by Cytoscape 3.8.2， and the average shortest path value of each drug putative target acting on neuropathic pain-related genes in this network was calculated by Pesca 3.8.0 tool so as to evaluate the network proximity between them， and screen prescription candidate targets with strong intervention efficiency and their corresponding potential effect components. After that， plasma and cerebrospinal fluid samples were collected from rats after administration of Ruyi Zhenbaowan at set time points， and the contents of potential effect components in samples was quantified by ultra performance liquid chromatography-quadrupole-ion trap mass spectrometry（UPLC-Q-TRAP/MS）， and drug concentration-time curves were plotted， then the pharmacokinetic parameters were calculated by DAS 2.1.1. ResultBy evaluating the network proximity between candidate targets and neuropathic pain-related genes in the interaction network， a total of 40 putative targets of Ruyi Zhenbaowan with strong intervention effects on neuropathic pain-related genes， such as estrogen receptor 1（ESR1）， cyclic adenosine monophosphate（cAMP）-dependent protein kinase catalytic subunit alpha（PRKACA） and protein kinase B1 （Akt1）， and 10 corresponding potential effect components， such as glycyrrhizic acid and betulinic acid， were obtained. Pharmacokinetic characterization showed that among the 10 potential effect components， gallic acid， apigenin-7-O-glucuronide， glycyrrhizic acid and apigenin were well absorbed and metabolized in plasma and cerebrospinal fluid， with long onset time and good bioavailability. ConclusionFrom the perspective of efficacy-target-constituent-pharmacokinetic， this study analyzes the main effective materials of Ruyi Zhenbaowan， such as glycyrrhizic acid， gallic acid， apigenin-7-O-glucuronide and apigenin， which have a high exposure in plasma or cerebrospinal fluid and have a strong intervention effect on neuropathic pain. The related results provide reliable experimental evidences for clarifying the material basis and developing quality standards of Ruyi Zhenbaowan.

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.

Objective:Osteosarcoma is a highly aggressive primary malignant bone tumor commonly seen in children and adolescents,with a poor prognosis.Anchorage-dependent cell death(anoikis)has been proven to be indispensable in tumor metastasis,regulating the migration and adhesion of tumor cells at the primary site.However,as a type of programmed cell death,anoikis is rarely studied in osteosarcoma,especially in the tumor immune microenvironment.This study aims to clarify prognostic value of anoikis and tumor immune microenvironment-related gene in the treatment of osteosarcoma. Methods:Anoikis-related genes(ANRGs)were obtained from GeneCards.Clinical information and ANRGs expression profiles of osteosarcoma patients were sourced from the therapeutically applicable research to generate effective therapies and Gene Expression Omnibus(GEO)databases.ANRGs highly associated with tumor immune microenvironment were identified by the estimate package and the weighted gene coexpression network analysis(WGCNA)algorithm.Machine learning algorithms were performed to construct long-term survival predictive strategy,each sample was divided into high-risk and low-risk subgroups,which was further verified in the GEO cohort.Finally,based on single-cell RNA-seq from the GEO database,analysis was done on the function of signature genes in the osteosarcoma tumor microenvironment. Results:A total of 51 hub ANRGs closely associated with the tumor microenvironment were identified,from which 3 genes(MERTK,BNIP3,S100A8)were selected to construct the prognostic model.Significant differences in immune cell activation and immune-related signaling pathways were observed between the high-risk and low-risk groups based on tumor microenvironment analysis(all P<0.05).Additionally,characteristic genes within the osteosarcoma microenvironment were identified in regulation of intercellular crosstalk through the GAS6-MERTK signaling pathway. Conclusion:The prognostic model based on ANRGs and tumor microenvironment demonstrate good predictive power and provide more personalized treatment options for patients with osteosarcoma.

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.

Methods:The HLEB-3 cells were cultured with different concentrations (0, 50, 100, 200, 500, 750 μmol/L) of H 2O 2.The cell inhibition rate was detected by the methyl thiazolyl tetrazolium (MTT) method, and the 50%inhibiting concentration (IC50) was calculated.HLEB-3 cells were cultured with different concentrations (0, 5, 10, 20, 50 μmol/L) of astaxanthin.The cell survival rate was detected by the MTT method.HLEB-3 cells were divided into four groups for 24-hour culture, namely normal control group cultured with complete medium, oxidative stress group cultured with 250 μmol/L H 2O 2, 10 μmol/L astaxanthin group cultured with 10 μmol/L astaxanthin and 250 μmol/L H 2O 2, and 20 μmol/L astaxanthin group cultured with 20 μmol/L astaxanthin and 250 μmol/L H 2O 2.The cell apoptosis rate was determined by flow cytometry.The nitric oxide (NO) concentration, superoxide dismutase (SOD) activity, glutathione (GSH) activity and malondialdehyde (MDA) content were detected by ELISA.The protein expressions of nuclear factor erythroid-2 related factor 2 (Nrf2) in nuclei, cytoplasmic Nrf2, heme oxygenase-1 (HO-1) and NAD (P) H, quinine oxidoreductase 1 (NQO1) were detected by Western bolt.The cells were divided into four groups, namely normal control-small interfering RNA (NC-siRNA) group, Nrf2-siRNA group, NC-siRNA+ astaxanthin group and Nrf2-siRNA+ astaxanthin group.The cells were transfected with NC-siRNA or Nrf2-siRNA accordingly.The cells were co-cultured for 24 hours with 0/10 μmol/L astaxanthin and 250 μmol/L H 2O 2 24 hours after transfection, respectively.The cell apoptosis rate was determined by flow cytometry.The NO concentration, SOD activity, GSH activity and MDA content were detected by ELISA. Results:With the increase of H 2O 2 concentration, the inhibition rate of HLEB-3 cells increased.There were significant differences in the inhibition rate of HLEB-3 cells treated with different concentrations of H 2O 2 ( F=12.358, P<0.05). The IC50 value of H 2O 2 on HLEB-3 cells was 264.20 μmol/L.The survival rates of HLEB-3 cells treated with 0, 5, 10, 20 and 50 μmol/L astaxanthin were (100.00±0.00)%, (102.20±1.34)%, (109.50±3.60)%, (115.40±4.13)%, (93.60±2.59)%, respectively.Then 10 μmol/L and 20 μmol/L were chosen as the experimental dose.The cell apoptosis rate of oxidative stress group was (38.50±2.38)%, which was higher than (9.20±0.24)% of normal control group, with a statistically significant difference ( P<0.05). The cell apoptosis rate of 10 μmol/L astaxanthin group was (27.60±4.33)%, which was lower than (38.50±2.38)% of oxidative stress group, but higher than (14.90±1.23)% of 20 μmol/L astaxanthin group and (9.20±0.24)% of normal control group, showing statistically significant differences (all at P<0.05). The NO and MDA contents were higher and the SOD and GSH concentrations were lower in oxidative stress group than in normal control group, 10 μmol/L astaxanthin group and 20 μmol/L astaxanthin group, and the differences were statistically significant (all at P<0.05). The NO and MDA contents were higher and the SOD and GSH concentrations were lower in 10 μmol/L astaxanthin group than in normal control group and 20 μmol/L astaxanthin groups, and the differences were statistically significant (all at P<0.05). There were significant differences in the relative expression levels of nuclear Nrf2, cytoplasmic Nrf2, HO-1 and NQO1 proteins among normal control group, oxidative stress group, 10 μmol/L astaxanthin group and 20 μmol/L astaxanthin group ( F=43.512, 20.381, 31.014, 23.435; all at P<0.001). The relative expression of nuclear Nrf2 protein gradually decreased, and the relative expression of nuclear Nrf2, HO-1 and NQO1 proteins increased gradually in normal control group, oxidative stress group, 10 μmol/L astaxanthin group and 20 μmol/L astaxanthin group, and there were significant differences when compared in pairs (all at P<0.05). The apoptosis rates of Nrf2-siRNA group and Nrf2-siRNA+ astaxanthin group were higher than those of NC-siRNA group and NC-siRNA+ astaxanthin group, and the differences were statistically significant (all at P<0.05). The cell apoptosis rate was higher in NC-siRNA group than in NC-siRNA+ astaxanthin group, showing a statistically significant difference ( P<0.05). There was no significant difference in the apoptosis rate between Nrf2-siRNA+ astaxanthin group and Nrf2-siRNA group ( P>0.05). The NO and MDA concentrations were higher and the SOD and GSH activities were lower in Nrf2-siRNA group than in the NC-siRNA group, with statistically significant differences (all at P<0.05). The NO and MDA concentrations were lower and the SOD and GSH activities were higher in NC-siRNA+ astaxanthin group than in NC-siRNA group and Nrf2-siRNA+ astaxanthin group, and the differences were statistically significant (all at P<0.05). There was no significant difference in NO and MDA concentrations or the SOD and GSH activities between Nrf2-siRNA+ astaxanthin group and Nrf2-siRNA group (all at P>0.05). Conclusions:Astaxanthin enhances the resistance of lens epithelial cells to H 2O 2-induced oxidative stress damage, which may be achieved by activating the Nrf2-related signaling 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.
