Objective To assess the clinical value of prognostic nutritional index(PNI)in predicting the prognosis of patients with advanced liver cancer treated with transarterial chemoembolization(TACE)combined with ablation therapy.Methods A total of 112 patients with advanced liver cancer,who received TACE combined with ablation at the Lishui Municipal Central Hospital of China from January 2020 to January 2024,were enrolled in this study.The general data,survival status,and survival time were collected.The Youden index of PNI was calculated using the receiver operating characteristic(ROC)curve model,and the optimal cutoff value was determined.Based on the optimal cutoff value,the patients were divided into low-PNI group and high-PNI group.The progression-free survival(PFS)and overall survival(OS)time were compared between the two groups,and the independent risk factors affecting PFS and OS were analyzed.Results The Youden index for PNI was 0.43,and the optimal cutoff value of PNI was 43.95.The low-PNI group included 65 patients,and the high-PNI group included 47 patients.There were no statistically significant differences in the baseline data between the two groups.The median PFS and the median OS in the high-PNI group were 13.21 months(95％CI=4.37-22.03)and 40.80 months(95％CI=31.55-50.05)respectively,which were longer than 9.20 months(95％CI=6.58-11.82)and 21.37 months(95％CI=16.56-26.17)respectively in the low-PNI group,the differences were statistically significant(both P＜0.05).The 6-month,one-year and 2-year PFS in the high-PNI group was 56.95％,47.25％and 33.87％respectively,which were higher than 43.95％,32.56％and 16.31％respectively in the low-PNI group.The one-year,2-year and 3-year cumulative survival rates in the high-PNI group were 80.77％,66.66％and 39.40％respectively,which were higher than 63.79％,34.31％and 27.75％respectively in the low-PNI group.Multivariate regression analysis indicated that the number of nodules,metastasis and PNI significantly affected OS,and metastasis and PNI strikingly affected PFS.High PNI was a protective factor for both PFS and OS.Conclusion For patients with advanced liver cancer treated with TACE combined with ablation therapy,PNI is an effective indicator for predicting the prognosis.

Objective To evaluate the combination score of albumin-bilirubin index(ALBI)and alkaline phosphatase(ALP)in predicting the prognosis of patients with cirrhosis complicated by portal hypertension after receiving transjugular intrahepatic portosystemic shunt(TIPS).Methods A total of 61 patients with cirrhosis complicated by portal hypertension,who received TIPS treatment at the Lishui Municipal Central Hospital of China from January 2016 to June 2024,were retrospectively collected.According to the Youden index of ALBI and ALP,the optimal cut-off values were calculated,and the patients were divided into low ALBI-low ALP group(0-point group),high ALBI-high ALP group(2-point group),and high ALBI-low ALP or low ALBI-high ALP group(one-point group).The efficacy of ALBI-ALP score in predicting the prognosis of patients was evaluated,and the survival rate and median survival time were compared between each other among the three groups.The independent risk factors affecting the survival time of patients were analyzed.Results The maximum Youden indexes of ALBI and ALP were 0.31 and 0.34 respectively,and the optimal cut-off values were-1.56 and 108.50 respectively.There were statistically significant differences in MELD score,Child-Pugh classification,and alanine aminotransferase level between each other among the three groups(all P＜0.05).The area under the ROC curve(AUC)of ALBI-ALP score was 0.77(95％ CI:0.66-0.89,P=0.000 2),which was better than 0.52 of the MELD score(95％ CI:0.37-0.67,P=0.77)as well as better than 0.57 of the Child-Pugh classification(95％ CI:0.43-0.72,P=0.34).The total mortality of patients was 49.18％.The mortality in the 0-point group was 11.11％(2/18),which was significantly lower than 59.46％(22/37)in the one-point group as well as than 100％(6/6)in the 2-point group,and the differences were statistically significant(x2=18.20,P＜0.001).In the 0-point group,as a large number of patients were still alive at the end of the study,the median survival time was unable to be calculated.The median survival time in the one-point group was 38.00 months(95％ CI:23.01-52.99 months),which in the 2-point group was only 1.00 month(95％ CI=0.00-2.60 months),the difference was statistically significant(x2=33.08,P＜0.000 1).In the 0-point group,one-point group and 2-point group,the one-year survival rates were 100％,66％ and 17％respectively,the 2-year survival rates were 100％,64％ and 17％ respectively,and the 3-year survival rates were 90％,53％ and 0％ respectively.Cox multivariate regression analysis showed that the combination score of ALBI and ALP(HR=7.11,95％ CI:2.95-17.15)was an independent risk factor for the survival time of patients with cirrhosis complicated by portal hypertension after receiving TIPS.Conclusion The combination score of ALBI and ALP can effectively predict the prognosis of patients with cirrhosis complicated by portal hypertension after receiving TIPS,and this score is an independent risk factor affecting the survival time of patients.

Objective:To investigate the correlation between statins and contrast-induced acute kidney injury (CI-AKI) and provide a reference basis for clinical practice.Methods:It was a retrospective cohort study. The adult patients were admitted to Peking University First Hospital from January 1, 2018, to December 31, 2020, and received at least one intravascular iodinated contrast administration during hospitalization. The clinical data of the patients were collected. The enrolled patients were divided into statin group and non-statin group according to statin exposure. The exposure of statins was defined as use of any type of statins within 48 hours before iodinated contrast administration. The primary outcome was in-hospital AKI defined as AKI developed after contrast administration and before discharge, with 30 days as the endpoint observation time, and the secondary outcome was post-contrast AKI (PC-AKI) defined as AKI onset within 72 hours after contrast administration. Cox regression model was applied to investigate the correlation between statin prescription prior to contrast administration and clinical outcomes. Pre-specified interaction analysis was conducted to examine modification effect of age, gender, baseline estimated glomerular filtration rate (eGFR), diabetes and the injection method of contrast.Results:Among 10 321 enrolled patients, the age was 63 (54, 71) years old, and 6 274 (60.8%) patients were males. There were 2 372 (23.0%) patients taking statins before the use of iodinated contrast agents, and the person-time incidence rate of in-hospital AKI was 2.5 per 1 000 person-days. The person-time incidence rate of statin users and statin non-users was 3.2 and 2.4 per 1 000 person-days, respectively. Compared with the non-statin group, age, serum creatinine and the proportions of males, admitted to the intensive care unit, lipid metabolism disorder, hypertension, diabetes, cerebrovascular diseases, cardiovascular diseases, using renin-angiotensin- aldosterone inhibitors, using diuretics, using non-steroidal anti-inflammatory drugs, using proton pump inhibitors, iodinated contrast administration via artery, eGFR<60 ml·min -1·(1.73 m 2) -1 were higher, while the proportions of general anesthesia surgery, severe liver diseases and tumors, and eGFR were lower in the statin group (all P<0.05). Among 10 321 patients, 5 867 patients had serum creatinine measurement within 72 hours after iodinated contrast administration, among which 70 patients (4.0 per 1 000 person-days) developed PC-AKI. Multivariate Cox regression analysis showed that statin use was an independent protective factor for in-hospital AKI ( HR=0.65, 95% CI 0.45?0.93, P=0.017) and PC-AKI ( HR=0.44, 95% CI 0.22?0.88, P=0.020). Subgroup analysis showed the significant interaction between diabetes and statin use ( P for interaction=0.039), and the protective effect of statins against in-hospital AKI was only observed in non-diabetic group ( HR=0.45, 95% CI 0.26?0.77). There were no significant differences in subgroups stratified by age, sex, baseline eGFR and the injection method of contrast (all P for interaction>0.05). Conclusions:Statin use prior to iodinated contrast administration is correlated with reduced risks of in-hospital AKI and PC-AKI in hospitalized patients, and the correlation between statin use and in-hospital AKI is more significant in non-diabetic patients. It is suggested that statin use before the application of iodinated contrast agents in hospitalized patients may prevent the occurrence of AKI.

Objective To describe the clinical features of patients with primary sclerosing cholangitis(PSC)in China based on a nationwide multicenter patient cohort,and to investigate the risk factors for prognosis.Methods A retrospective cohort study was conducted among the patients with a confirmed diagnosis of PSC based on the electronic medical record system of seven grade A tertiary hospitals across the country,and related data were extracted.The Mann-Whitney U test was used for comparison of continuous data between groups,and the chi-square test was used for comparison of categorical data between groups.The Kaplan-Meier method was used to estimate liver transplant-free survival,and the log-rank test was used for comparison of survival rate between PSC patients with different features.The Cox regression model was used to identify independent risk factors for the prognosis of PSC patients and the interactions between key factors.Results A total of 107 patients were enrolled,among whom 55.6%(55/99)had large-duct PSC and 29.0%(31/107)had comorbidity with inflammatory bowel disease(IBD).The positivity rate of anti-neutrophil cytoplasmic antibody(ANCA)was 32.9%(24/73),and 50.0%(40/80)of the patients had an increase in IgG/IgM.The median symptom-to-diagnosis interval was 1 year(<1-4.0),and 38.3%(41/107)of the patients had progressed to decompensated cirrhosis at the time of diagnosis.The median liver transplant-free survival time was 114 months(95%confidence interval[CI]:62-166),with a 5-year survival rate of 65.7%.The multivariate analysis showed that an increase in total bile acid(TBA)(hazard ratio[HR]=1.006,95%CI:1.002-1.010,P=0.001)and a prolonged symptom-to-diagnosis interval(HR=1.252,95%CI:1.059-1.480,P=0.009)were independent risk factors for prognosis.The interaction analysis showed that compared with the female patients with TBA<50 μmol/L,both male and female patients with TBA≥50 μmol/L had a significant increase in the risk of liver transplantation or death(male:HR=16.563,95%CI:2.103-130.449,P<0.001;female:HR=17.009,95%CI:2.113-136.934,P<0.001),and compared with the patients with an age of<45 years and a TBA level of<50 μmol/L,the patients with an age of≥45 years and a TBA level of≥50 μmol/L had a significant increase in the risk of liver transplantation or death(HR=10.729,95%CI:1.325-86.859,P=0.026).Compared with the female patients with an symptom-to-diagnosis interval of≤2 years,the male patients with a symptom-to-diagnosis interval of>2 years had an increased risk of liver transplantation or death(HR=4.825,95%CI:1.725-13.644,P=0.003),and compared with the patients with an age of<45 years and a symptom-to-diagnosis interval of≤2 years,the patients with an age of<45 years and a symptom-to-diagnosis interval of>2 years had an increased risk of liver transplantation or death(HR=4.983,95%CI:1.366-18.173,P=0.015).Conclusion Compared with the reports from Western countries,large-duct PSC is also the main type of PSC in China,but with a relatively low proportion,and there is also a relatively low proportion of patients with IBD or positive ANCA.An increase in TBA and a prolonged symptom-to-diagnosis interval are independent risk factors for prognosis,with significant interactions with age and sex.This suggests that early screening and intervention should be enhanced to improve prognosis.

Objective:To analyze the antimicrobial resistance and genomic characteristics of Salmonella typhimurium and its monophasic variants isolated from human and food sources in Hangzhou. Methods:A total of 186 Salmonella typhimurium and its monophasic variants isolated in Hangzhou during the period from 2017 to 2021 were subjected to antimicrobial susceptibility testing and whole-genome sequencing, and the genomes from public databases were downloaded. Multilocus sequence typing and the identification of antimicrobial resistance (AMR) genes were performed using the sequencing data. Phylogenetic tree based on the single nucleotide polymorphism (SNP) sites in the genomes from Hangzhou and public databases was constructed. Results:The multidrug resistance (MDR) rate of the monophasic variant strains in Hangzhou was 95.4% (103/108). The MDR strains harbored ≥3 classes of AMR genes simultaneously and the most common resistance genotype was blaTEM-1B- tet( B)- sul2- aac(6′)- Ia (44.7%, 46/103). The MDR rate of Salmonella typhimurium strains was 75.6% (59/78), and 52.5% (31/59) of the MDR strains harbored ≥10 AMR genes simultaneously, with the most common resistance genotype being blaTEM-1B- qnrS1- tet( A)- tet( M)- cmlA1- floR- dfrA12- sul2- sul3- aac(6′)- Iaa (40.7%, 24/59). All of the 186 strains were positive for AMR gene aac (6 ′)- Iaa, and three monophasic variant strains which were resistant to polymyxin E was positive for mcr-1.1. ST19 accounted for 91.0% of the 78 Salmonella typhimurium strains (except for two strains belonging to ST34, two strains belonging to ST1544, and three strains untyped), and ST34 accounted for 96.3% of the 108 monophasic variant strains (except for four strains untyped). The phylogenetic tree showed that the ST19 strains dominated by serotype typhimurium and the ST34 strains dominated by monophasic variants were divided into two clades. In the ST19 clade, strains from Hangzhou were mainly clustered with the strains from other cities in Zhejiang Province as well as other provinces and cities in China, such as Jiangxi, Shanghai, and Shandong. Strains isolated from pig, duck, and chicken were the ones that were clustered with clinical strains. In the ST34 clade, most strains from Hangzhou were clustered together, and some strains were clustered with those isolated from other cities in Zhejiang Province as well as Beijing, Guangdong, Shanghai, etc. Strains isolated from pig and chicken were the ones that were clustered with clinical strains. Conclusions:The MDR rate of monophasic variant strains is higher than that of Salmonella typhimurium strains, and the latter is prominent by its harboring multiple AMR genes. The epidemic of Salmonella typhimurium and its monophasic variants in Hangzhou is mainly caused by the spread of ST19 and ST34 strains, respectively, and the clinical infection may be closely related to the consumption of pork and poultry meat. While transmitting locally, cross-region transmission of the two serovars in Zhejiang Province and cross-province transmission in China may also occur.

Anticancer drugs are important causes of kidney injury in cancer patients. Once kidney injury occurs, it will affect anticancer therapy and patient prognosis. Thus, the Japanese Society of Nephrology, Japan Society of Clinical Oncology, Japanese Society of Medical Oncology, and Japanese Society of Nephrology and Pharmacotherapy have jointly formulated the Clinical Practice Guidelines for Management of Kidney Injury During Anticancer Drug Therapy 2022 and made a particular discussion on the prevention and management of anticancer drug-induced kidney injury. This article focuses on interpreting the management of kidney injury related to cytotoxic anticancer drugs, targeted therapies, and immune checkpoint inhibitors to more effectively guide clinical practice.
