In order to improve the catalytic performance of the nitrobenzene hydrogenation rearrangement to prepare p-aminophenol,a bimetallic Pt-Ni/C(PNC)catalyst was synthesized.Taking advantage of the synergistic effect of Ni and Pt to enhance product selectivity and catalytic performance stability,the electrons in Ni are moved to Pt by the electron effect,which affects the catalyst’s ability to activate H_(2)as well as the amount of hydrogen activated.Furthermore,due to the strong Pt(5d)-Ni(3d)coupling effect,Ni can effectively maintain Pt stability in the acidic system and reduce Pt dissolution.The stability of the PNC can be found to be greatly enhanced compared to the Pt/C(PC)catalyst,and p-aminophenol selectivity is greatly enhanced,showing excellent catalytic performance. 展开更多

This strain was identified by gene sequence identification. The antioxidant and anti-inflammatory capacity of ferulic acid released from wheat bran by this A. niger strain(FA-WB) were evaluated. Methods Molecular identification techniques based on PCR analysis of specific genomic sequences were conducted; antioxidant ability was examined using oxygen radical absorbance capacity(ORAC), cellular antioxidant activity(CAA) assays, and erythrocyte hemolysis assays. RAW264.7 cells were used as a model to detect anti-inflammatory activity. Results The filamentous fungal isolate was identified to be A. niger. ORAC and CAA assay showed that FA-WB had better antioxidant activity than that of the ferulic acid standard. The erythrocyte hemolysis assay results suggested that FA-WB could attenuate AAPH-induced oxidative stress through inhibition of reactive oxy gen species(ROS) generation. FA-WB could significantly restore the AAPH-induced increase in intracellular antioxidant enzyme activities to normal levels as well as inhibit the intracellular malondialdehyde formation. TNF-?, IL-6, and NO levels indicated that FA-WB can inhibit the inflammation induced by lipopolysaccharide(LPS). Conclusion Ferulic acid released from wheat bran by a new strain of A. niger had good anti-inflammatory activity and better antioxidant ability than standard ferulic acid. 展开更多

Laparoscopic hepatectomy(LH)is a newly developed technique associated with advantages as open surgery,but the study on outcome of liver function recovery was scarce.This preliminary report was aimed to comparatively assess the short?term outcomes between LH and open hepatectomy(OH)for primary hepatocellular carcinoma(PHC).This study retrospectively analyzed the demographic data and short-term outcomes of 81 patients who underwent LH or OH for the primary treatment of PHC between Oct.2017 and May 2018 at Union Hospital,Tongji Medical College,Huazhong University of Science and Technology(China).A total of 81 PHC patients who received major liver resection were enrolled.There were 38(47%)patients in the LH group and 43(53%)patients in the OH group.The operative time was significantly longer(373.53±173.38 vs.225.43±55.08,P<0.01),and hospital stay(17.34±5.93 vs.21.70±6.89,P=0.003),exhaust time(2.32±0.62 vs.3.07±0.59,P<0.01)and defecation time(2.92±0.78 vs.3.63±0.58,P<0.01)were significantly shorter in LH group than in OH group.The recovery of liver function was significantly faster in LH group,including higher serum albumin(P=0.002),higher ratio of albumin/globulin(P=0.029)and lower direct bilirubin(P=0.001)than in OH group.It is suggested that LH can serve as a fast recovery and cheap surgical procedure in the treatment of PHC,which is safe and feasible. 展开更多

AIM To describe the prevalence of posttransplant metabolic syndrome(PTMS) after donation after cardiac death(DCD) liver transplantation(LT) and the pre-and postoperative risk factors.METHODS One hundred and forty-seven subjects who underwent DCD LT from January 2012 to February 2016 were enrolled in this study. The demographics and the clinical characteristics of pre-and post-transplantation were collected for both recipients and donors. PTMS was defined according to the 2004 Adult Treatment Panel-Ⅲ criteria. All subjects were followed monthly for the initial 6 mo after discharge, and then, every 3 mo for 2 years. The subjects were followed every 6 mo or as required after 2 years post-LT.RESULTS The prevalence of PTMS after DCD donor orthotopic LT was 20/147(13.6%). Recipient's body mass index(P = 0.024), warm ischemia time(WIT)(P = 0.045), and posttransplant hyperuricemia(P = 0.001) were significantly associated with PTMS. The change in serum uric acid levels in PTMS patients was significantly higher than that in non-PTMS patients(P < 0.001). After the 1 s t mo, the level of serum uric acid of PTMS patients rose continually over a period, while it was unaltered in non-PTMS patients. After transplantation, the level of serum uric acid in PTMS patients was not associated with renal function.CONCLUSION PTMS could occur at early stage after DCD LT with growing morbidity with the passage of time. WIT and post-LT hyperuricemia are associated with the prevalence of PTMS. An increased serum uric acid level is highly associated with PTMS and could act as a serum marker in this disease. 展开更多

AIM:To investigate the role of tumor microenvironment(TME)-related long non-coding RNA(lncRNA)in uveal melanoma(UM),probable prognostic signature and potential small molecule drugs using bioinformatics analysis.METHODS:UM expression profile data were downloaded from the Cancer Genome Atlas(TCGA)and bioinformatics methods were used to find prognostic lncRNAs related to UM immune cell infiltration.The gene expression profile data of 80 TCGA specimens were analyzed using the single sample Gene Set Enrichment Analysis(ss GSEA)method,and the immune cell infiltration of a single specimen was evaluated.Finally,the specimens were divided into high and low infiltration groups.The differential expression between the two groups was analyzed using the R package‘edge R’.Univariate,multivariate and Least Absolute Shrinkage and Selection Operator(LASSO)Cox regression analyses were performed to explore the prognostic value of TMErelated lncRNAs.Gene Ontology and Kyoto Encyclopedia of Genes and Genomes(KEGG)functional analyses were also performed.The Connectivity Map(CMap)data set was used to screen molecular drugs that may treat UM.RESULTS:A total of 2393 differentially expressed genes were identified and met the criteria for the low and high immune cell infiltration groups.Univariate Cox analysis of lncRNA genes with differential expression identified 186 genes associated with prognosis.Eight prognostic markers of TME-included lncRNA genes were established as potentially independent prognostic elements.Among 269 differentially expressed lncRNAs,69 were up-regulated and 200 were down-regulated.Univariate Cox regression analysis of the risk indicators and clinical characteristics of the 8 lncRNA gene constructs showed that age,TNM stage,tumor base diameter,and low and high risk indices had significant prognostic value.We screened the potential small-molecule drugs for UM,including W-13,AH-6809 and Imatinib.CONCLUSION:The prognostic markers identified in this study are reliable biomarkers of UM.This study expands our current understanding of the role of TME-related lncRNAs in UM genesis,which may lay the foundations for future treatment of this disease. 展开更多

BACKGROUND Graft-versus-host disease(GVHD)following liver transplantation(LT)is an unpredictable complication with poor outcome.However,consensus regarding the diagnosis and therapeutic regimen for the disease is yet lacking.The present study summarized the clinical experience on the diagnosis and treatment of acute GVHD(aGVHD)following LT and reviewed the pertinent literature.CASE SUMMARY Between January 1^(st),2000 and December 31^(st),2020,a total of 1053 LT were performed in the First Affiliated Hospital of Xi’an Jiaotong University.Six recipients developed aGVHD with clinical symptoms of fever,rash,diarrhea,and pancytopenia.The incidence of aGVHD was 0.57%.The median time from LT to the clinical presentation of aGVHD was 22.17 d.The median time from the beginning of the clinical symptom to histopathological diagnosis was 7.5 d.All six cases underwent treatment of immunosuppressant adjustment,corticosteroids,human normal immunoglobulin,and antithymocyte globulin/IL-2 antagonists.Despite intensive treatment strategies,4 patients were deceased due to sepsis,multiple organ failure,and cerebral hemorrhage.The remaining two cases were discharged as treatment successfully.However,one died because of tuberculosis infection on the 6 th month of follow-up,the other one was alive healthy during 30 mo of follow-up.CONCLUSION The rapid diagnosis of aGVHD is mainly based on the time from the first symptom,histopathological features,and the donor T-lymphocyte chimerism.Our cases report highlights massive corticosteroid therapy and age difference between donors and recipients could accelerate to aGVHD.Moreover,gut microbial interventions and donor-targeted serotherapy may provide novel therapeutics. 展开更多

Mammalian target of rapamycin(m TOR) inhibitor as an attractive drug target with promising antitumor effects has been widely investigated. High quality clinical trial has been conducted in liver transplant(LT) recipients in Western countries. However, the pertinent studies in Eastern world are paucity. Therefore, we designed a clinical trial to test whether sirolimus can improve recurrence-free survival(RFS) in hepatocellular carcinoma(HCC) patients beyond the Milan criteria after LT. This is an open-labeled, single-arm, prospective, multicenter, and real-world study aiming to evaluate the clinical outcomes of early switch to sirolimus-based regimens in HCC patients after LT. Patients with a histologically proven HCC and beyond the Milan criteria will be enrolled. The initial immunosuppressant regimens are center-specifc for the frst 4-6 weeks. The following regimens integrated sirolimus into the regimens as a combination therapy with reduced calcineurin inhibitors based on the condition of patients and centers. The study is planned for 4 years in total with a 2-year enrollment period and a 2-year follow-up. We predict that sirolimus conversion regimen will provide survival benefts for patients particular in the key indicator RFS as well as better quality of life. If the trial is conducted successfully, we will have a continued monitoring over a longer follow-up time to estimate indicator of overall survival. We hope that the outcome will provide better evidence for clinical decision-making and revising treatment guidelines based on Chinese population data. 展开更多
