ObjectiveTo investigate the application of the novel inflammatory factor adsorption column CA280 combined with low-dose plasma exchange （LPE） in patients with acute-on-chronic liver failure （ACLF）. MethodsA prospective cohort study was designed， and a total of 93 ACLF patients who were admitted to The Ninth Hospital of Nanchang from June 2023 to January 2025 were enrolled and randomly divided into DPMAS+LPE group with 50 patients and CA280+LPE group with 43 patients. In addition to comprehensive medical treatment， the patients in the DPMAS+LPE group received DPMAS and LPE treatment， and those in the CA280+LPE group received CA280 and LPE treatment. The two groups were observed in terms of routine blood test results， liver function parameters， renal function markers， electrolytes， coagulation function parameters， cytokines， adverse events， and 28-day prognosis before surgery （baseline）， during surgery （DPMAS or CA280）， and after surgery （after sequential LPE treatment）. The paired t-test was used for comparison of normally distributed continuous data before and after treatment within each group， and the independent-samples t test was used for comparison between groups； the Wilcoxon signed-rank test was used for comparison of non-normally distributed continuous data before and after treatment within each group， and the Mann-Whitney U test was used for comparison between groups. The chi-square test or the Fisher’s exact test was used for comparison of categorical data between groups， and the Spearman test was used for correlation analysis. ResultsAfter CA280 treatment， the ACLF patients had significant reductions in the levels of cytokines （IL-6， IL-8， IL-10， TNF-α， and IFN-γ）， liver function parameters （ALT， AST， ALP， TBil， DBil， Alb， and glutathione reductase）， and the renal function marker urea nitrogen （all P<0.05）， and in terms of coagulation function parameters， there were significant increases in prothrombin time， activated partial thromboplastin time （APTT）， thrombin time， and international normalized ratio （INR） and significant reductions in prothrombin activity （PTA） and fibrinogen （FIB） （all P<0.05）. Compared with the DPMAS+LPE group， the CA280+LPE group showed better improvements in the serum cytokines IL-8 （Z=-2.63， P=0.009）， IL-10 （Z=-3.94， P<0.001）， and TNF-α （Z=-1.53， P=0.023）， and the two artificial liver support systems had a similar effect in improving liver function （ALT， AST， GGT， GR， TBil， and DBil） （all P >0.05）， but the CA280+LPE group showed a significantly greater reduction in Alb （Z=-2.08， P=0.037）. CA280+LPE was more effective in reducing uric acid （Z=-2.97， P=0.003）. Compared with DPMAS+LPE， CA280+LPE treatment resulted in a significant reduction in INR （Z=-4.01， P<0.001）， a significant increase in APTT （Z=-2.53， P=0.011）， and significant greater increases in PTA （Z=-6.28， P<0.001） and FIB （Z=-3.93， P<0.001）. There were no significant differences in the incidence rates of adverse reactions and the rate of improvement at discharge between the two groups （all P>0.05）. The Spearman correlation analysis showed that IL-6 was significantly correlated with WBC （r=0.22， P=0.042）， TBil （r=0.29， P=0.005）， and FIB （r=-0.33， P=0.003）； IL-8 was positively correlated with APTT （r=0.37， P<0.001） and INR （r=0.25， P=0.013）； TNF-α was significantly correlated with WBC （r=0.40， P<0.001） and TBil （r=0.34， P<0.001）. ConclusionCompared with DPMAS， CA280 combined with LPE can effectively clear proinflammatory cytokines and improve liver function in ACLF patients， but it has a certain impact on Alb and coagulation function. This regimen provides a new option for the individualized treatment of ACLF and can improve the short-term prognosis of patients， but further studies are needed to verify its long-term efficacy.

ObjectiveTo investigate the clinical application value of a predictive model for the efficacy of third-generation cephalosporin in the treatment of community-acquired spontaneous bacterial peritonitis （CASBP）. MethodsThis prospective study was conducted among 50 patients with liver cirrhosis and CASBP who were admitted to The Ninth Hospital of Nanchang from January 2021 to June 2022， and the patients were randomly divided into optimized treatment group and traditional treatment group， with 25 patients in each group. The patients in the optimized treatment group received ceftazidime or imipenem for initial treatment based on the above predictive model， and those in the traditional treatment group received ceftazidime for initial treatment， with the subsequent use of antibiotics adjusted based on the efficacy of initial treatment. The two groups were compared in terms of the response rate of initial treatment， cure rate on day 5， and 30-day mortality rate. The independent-samples t test or 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. ResultsAll patients completed the study. The optimized treatment group had a significantly higher response rate of initial treatment than the traditional treatment group （88.0% vs 60.0%， χ²=5.094， P=0.024）， while there was no significant difference in the cure rate on day 5 between the two groups （80.0% vs 56.6%， χ²=3.309， P=0.069）. As for the patients who received ceftazidime for initial treatment， the optimized treatment group had a significantly higher response rate of initial treatment than the traditional treatment group （88.9% vs 60.0%， χ²=4.341， P=0.037）， while there was no significant difference in the cure rate on day 5 between the two groups （83.3% vs 56.0%， χ²=2.425， P=0.119）. There was no significant difference in 30-day mortality rate between the two groups （8.0% vs 20.0%， χ²=0.664， P=0.415）. For all patients， there was a significant association between response of initial treatment and cure on day 5 （odds ratio ［OR］=9.643， 95% confidence interval ［CI］： 2.292‍ — ‍40.564） and between cure on day 5 and 30-day mortality （OR=0.138， 95%CI： 0.023‍ — ‍0.813）. ConclusionThis predictive model for efficacy helps clinicians to identify the patients who can benefit from third-generation cephalosporin treatment and improve the efficacy of third-generation cephalosporin in the initial empirical treatment of CASBP.

Objective To investigate the prognosis and adverse reactions of patients with acute-on-chronic liver failure (ACLF) receiving artificial liver support therapy stratified by international normalized ratio (INR). Methods A total of 515 ACLF patients who received artificial liver support therapy in Department of Severe liver Disease, The Ninth Hospital of Nanchang, from January 2010 to May 2020 were enrolled, and according to the level of INR, they were divided into group A with 20 patients (INR < 1.5), group B with 115 patients (1.5≤INR < 1.9), group C with 179 patients (1.9≤INR < 2.6), group D with 61 patients (2.6≤INR < 3.2), group E with 75 patients (3.2≤INR < 4.2), and group F with 65 patients (INR≥4.2). All patients received multimodality medical treatment combined with artificial liver support therapy. The one-way analysis of variance was used for comparison of normally distributed continuous data between multiple groups; the Kruskal-Wallis H test was used for comparison of non-normally distributed continuous data between multiple groups。The chi-square test was used for comparison of categorical data between groups. Bonferroni correction was used for further comparison between two groups. and the receiver operating characteristic (ROC) curve was used to evaluate the value of INR and MELD scoring system in predicting the prognosis of ACLF patients. Results As for 90-day mortality rate, there was a significant difference between the six groups stratified by INR ( χ 2 =124.84, P < 0.001); there was no significant difference between groups A(25%), B(25.2%), and C(39.7%) ( P > 0.05), and there was a significant difference between groups D/E/F(65.6%, 82.7%, and 92.3%, respectively) and groups A/B/C (all P < 0.05); there was no significant difference between groups D and E and between groups E and F ( P > 0.05), and there was a significant difference between groups D and F ( P < 0.05). There was no significant difference in the incidence rate of intraoperative adverse reactions between the six groups ( χ 2 =8.956, P =0.111). INR had an area under the ROC curve of 0.786 (95% confidence interval: 0.746-0.825, P < 0.001) in predicting the prognosis of patients with ACLF receiving artificial liver support therapy, with a sensitivity of 66.7% and a specificity of 79.8%. Conclusion INR has a good value in predicting the prognosis of ACLF patients receiving artificial liver support therapy, and the artificial liver has good safety.

Objective To investigate the factors for predicting the efficacy of third-generation cephalosporin (3 rd GC) in the treatment of community-acquired spontaneous bacterial peritonitis (CASBP), and to establish and validate an efficacy predictive model for 3 rd GC in the treatment of CASBP. Methods A retrospective analysis was performed for the clinical data of the patients with liver cirrhosis and CASBP who received 3 rd GC monotherapy for initial treatment in The Ninth Hospital of Nanchang, and according to their treatment outcome, they were divided into non-response group and response group. The patients hospitalized from 2013 to 2018 were included in the modeling cohort (55 patients the non-response group and 110 in the response group), and those hospitalized from 2019 to 2020 were included in the validation cohort (17 patients in the non-response group and 43 in the response group). In the modeling cohort, the two groups were compared in terms of the indices including general information, underlying diseases, past history, clinical manifestation, and laboratory test results. Univariate analyses (the 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 chi-square test or the Fisher's exact test was used for comparison of categorical data between groups) and a binary Logistic regression analysis were used to identify efficacy predictors, and an efficacy predictive model was established based on the logistic regression equation. The receiver operating characteristic (ROC) curve was plotted to perform internal and external validations of the model in the modeling cohort and the validation cohort, respectively. Results The study population had a mean age of 51.6±12.0 years, and male patients accounted for 80.0%; hepatitis B was the main cause of liver cirrhosis (66.7%), and 3 rd GC had an overall response rate of 68.0%. In the modeling cohort, compared with the response group, the non-response group had significantly lower proportion of patients with the first onset of SBP, polymorphonuclear (PMN) count in ascites, and leukocyte count in ascites (all P < 0.05), as well as significantly higher proportion of patients with exposure to broad-spectrum antibiotic and platelet count (both P < 0.05). The Logistic regression analysis showed that the first onset of SBP (odds ratio [ OR ]=0.158, 95% confidence interval [ CI ]: 0.064-0.392, P < 0.001), ascites PMN count ( OR =0.728, 95% CI : 0.530-0.998, P =0.046), exposure to broad-spectrum antibiotic ( OR =9.152, 95% CI : 1.513-55.351, P =0.016), and platelet count ( OR =1.012, 95% CI : 1.006-1.019, P < 0.001) were independent predictive factors for non-response to 3 rd GC. The efficacy predictive model had an area under the ROC curve (AUC) of 0.840, and based on the maximum Youden index, predictive score ≥ 0.207 was the optimal cut-off value for predicting non-response, with a corresponding Youden index of 0.536, a sensitivity of 89.1%, a specificity of 63.6%, a positive predictive value of 55.1%, and a negative predictive value of 92.1%. This model had an AUC of 0.837 in the validation cohort. Conclusion The first onset of SBP and higher ascites PMN count are the protective factors against non-response to 3 rd GC for the treatment of CASBP, and exposure to broad-spectrum antibiotic and higher platelet count are the risk factors for such non-response. The model established for predicting the efficacy of 3 rd GC in the treatment of CASBP has good predictive performance and thus holds promise for clinical application.

Objective To evaluate the therapeutic effect and safety of bilirubin absorption(BA) combined with low volume plasma exchange(PE) in the treatment of severe hepatitis.Methods Forty-five inpatients with severe hepatitis in this hospital from January 1,2015 to December 31,2016 were performed the prospective study.All cases were given the therapy of BA combined with low volume PE.The indicators of liver function (ALT,AST,TBIL,CHE,ALB),coagulation function (PTA,INR),blood routine (WBC,Hb,PLT),electrolytes(K+,Na+,Cl-,Ca2+) and renal function(BUN,Cr) were collected before and after treatment.The changes of clinical symptoms and signs(weak,anorexia,abdominal distension,etc.) before and after treatment were recorded in all cases.The complications during the treatment process were also observed and recorded.The t-test was used for the inter-group comparison of the measurement data and the abnormal distribution adopted the Wilcoxon rank sum test.Results After the treatment of BA and low volume PE,the clinical symptoms of the patients were improved in different levels.The levels of ALT,AST and TBIL were decreased(P＜0.01),the CHE level was increased(P＜0.01),ALB level was decreased(P＜0.01);PTA was increased(P＜0.05),INR was decreased(P＜0.01);WBC,HGB and PLT were decreased(P＜0.05).Nineteen cases(31.1％) developed adverse reactions,which were recovered to normal after general symptomatic treatment.The treatment compliance was good without influence on artificial liver therapy.Conclusion BA combined low volume PE for treating severe hepatitis can significantly improve the liver function with safety and effectiveness.

ObjectiveTo investigate the nutritional risk incidence and clinical outcome in.hospitalized patients with liver diseases.MethodsThe data of 390 cases of liver disease inpatients were studied.The nutritional status of the enrolled patients was assessed with Nutritional Risk Screening 2002.ResultsThe total incidence of nutritional risk in the liver disease patients was 47.95％.The incidence was 81.82％ in severe hepatitis patients,significantly higher that that in acute hepatitis patients (43.33％,P =0.013) and chronic hepatitis patients (28.30％,P =0.000).The incidence of nutritional risk was 75.79％ in hepatic cirrhosis patients,also significantly higher than that in acute hepatitis patients (P =0.000) and chronic hepatitis patients (P =0.000).ConclusionSevere hepatitis and hepatic cirrhosis patients may have higher nutritional risk than acute and chronic hepatitis patients.

Objective To detect the levels of tumor necrosis factor (TNF)-a,interleukin (IL)-1β,IL-2,1L-6,IL-8,1L-10,IL-12 and interferon (IFN)-α in the serum and cerebrospinal fluid of the patients with epidemic encephalitis B,and to investigate the roles in pathogenesis of epidemic encephalitis B.Methods Approximately of 2 mL serum and 2 mL cerebrospinal fluid from 24 patients with epidemic encephalitis B during acute phase were collected,and 2 mL serum from 20 healthy controls were collected.The levels of eytokines in serum and cerebrospinal fluid were detected by enzyme linked immunosorbent assay (ELISA).Means of multi-sample were compared by analysis of variance and means of two-sample were compared by t test.Results The levels of TNF-α,IL-1β,IL-6,IL-8,IL-10 and IFN-α in eerebrospinal fluid were (24.5±6.6),(7.8±2.4),(16.0±5.7),(17.6±4.8),(130.2±33.6) and (45.2±10.8) ng/L,respectively,and in serum were (25.3±11.2),(7.1±3.2),(14.5±6.2),(16.0±6.5),(82.0±27.8) and (42.5±16.2) ng/L,respectively.The levels of TNF-α,IL-1β,IL-6,IL-8,IL-10 and IFN-α in serum and cerebrospinal fluid from patients with epidemic encephalitis B were all higher than those in serum of healthy controls [(12.7±7.9),(2.6±1.0),(6.2±2.2),(9.6±3.3),(71.4±12.8) and (30.0±14.0) ng/L;F value was 14.10,29.46,23.38,14.78,32.59,7.52;all P＜0.01];while the levels of IL-2 and IL-12 were not increased significantly.The levels of IL-1β,IL-6,IL-8,IL-10,IL-12 and IFN-α in cerebrospinal fluid were higher than those in serum,while the levels of TNF-± and IL-2 in cerebrospinal fluid were lower than those in serum.The levels of IL-6 and IL-8 in cerebrospinal fluid from patients with severe type of epidemic encephalitis B were (18.8±5.4) ng/L and (20.7±2.7) ng/L,and were higher than those with common type [(12.1±3.0) and (13.3±3.3) ng/L;t=3.50,t=5.96;P＜0.05],while the levels of IL-2 in serum and in cerebrospinal fluid from patients with severe type were lower than those with common type. Conclusions Oversecretions of TNF-α,IL-1β,IL-6,IL-8,IL-10 and IFN-a are involved in the inflammatory damage of epidemic encephalitis B,while under-secretions of IL 2 and ILl2 may be involved in cellular immune responses.
