Beneficial Effects of Traditional Chinese Medicine Fuzheng Huayu on the Occurrence of Hepatocellular Carcinoma in Patients with Compensated Chronic Hepatitis B Cirrhosis Receiving Entecavir:A Multicenter Retrospective Cohort Study

Background and Aims:The application of antifibrotic drugs to treat patients with chronic liver diseases who are receiving antiviral therapies for hepatocellular carcinoma(HCC)has not been established.Here,we aimed to assess the impact of the Traditional Chinese Medicine Fuzheng Huayu(FZHY)on the occurrence of HCC in patients with hepatitis B virus-related compensated cirrhosis receiving the antiviral drug entecavir(ETV).Methods:A multicenter retrospective cohort study was performed.Compensated liver cirrhosis patients were divided into the ETV+FZHY group or the ETV group according to treatment.The cumulative incidence of HCC was analyzed using Kaplan-Meier and log-rank tests.Propensity score matching was used for confounding factors.Stratified analysis and Cox regression were used to determine the effects of FZHY on the occurrence of HCC and liver function decompensation.Results:Out of 910 chronic hepatitis B patients,458 were in the ETV+FZHY group and 452 were in the ETV group.After propensity score matching,the 5-year cumulative incidence of HCC was 9.8%in the ETV+FZHY group and 21.8%in the ETV group(p<0.01).The adjusted hazard ratio for HCC was 0.216(0.108,0.432)when FZHY treatment was>36 months.Age,diabetes,alanine aminotransferase,-glutamyl transpeptidase,albumin,hepatitis B e-antigen,and fibrosis 4 score were associated with the occurrence of HCC.FZHY decreased the risk of HCC in patients aged>45 years with a hepatitis B virus DNA level of2,000 IU/l.Conclusion:Adjunctive FZHY treatment reduced HCC occurrence in patients with hepatitis B virus cirrhosis who were treated with ETV,possibly due to the antifibrotic properties of FZHY.

Diagnosis and subtype classification on serum peptide fingerprints by mesoporous polydopamine with built-in metal-organic framework

Crohn's disease(CD)as a big issue to public health needs an accurate diagnosis urgently that is the common challenge among internal diseases.Herein,we design a mesoporous polydopamine with builtin metal-organic frameworks(dubbed MMP-b-MOFs)to combine with high-throughput mass spectrometry to extract serum peptide fingerprints from CD and healthy controls(HC).Benefitting by the sizeexclusion and strong hydrophilicity of MMP-b-MOFs,the extracted peptide fingerprints present extremely high quality.CD and HC are explicitly discriminated with orthogonal partial least squares discriminant analysis(OPLS-DA),the corresponding area under the curve(AUC)value is 1.000.Moreover,eight peptides with clear identity are screened out and achieve the accurate diagnosis and subtype classification of CD,with all AUC values up to 1.000.Moreover,the unsupervised model is also established to precisely classify HC and CD based on these eight clearly identified peptides.This work brings great benefits for clinical detection especially internal medicine.

Comprehensive treatment of acute-on-chronic liver failure in a patient with hepatitis B： a case report

The clinical data of a patient with acute-on-chronic liver failure were analyzed retrospectively. The patient has suffered from hepatitis B for 30 years. His liver function deteriorated, yielding Child-Pugh grade C and reaching a model for end-stage liver disease score of 33 points within a short period; this condition was complicated with highly active variceal bleeding and coagulation system failure （PT 〉 100 s）. The patient also presented hepatocellular carcinoma. Comprehensive treatments included effective inhibition of hepatitis B virus replication and intensive care support. Piggyback orthotopic liver transplantation was performed as the final treatment. The patient recovered uneventfully and was discharged after surgery.

The cytotoxicity of oxidized multi-walled carbon nanotubes on macrophages

Carbon nanotubes(CNTs) have been developed for medical and biotechnological applications in the past decades. Their widespread applications make it important to understand their potential hazards to human and the environment. In this study, the possible toxicological effects of the oxidized multi-walled carbon nanotubes(O-MWCNTs) were assessed on RAW 264.7 macrophages in vitro. Several toxicological endpoints, such as cell viability, the release of LDH and IL-8, GSH/GSSG ratio, intracellular calcium concentration and ultrastructural changes in cell morphology, were carried out. The results showed that O-MWCNTs had very limited effects on oxidative stress, cellular toxicity and apoptosis. Transmission electron microscope clearly demonstrates RAW 264.7 macrophages engulfed plenty of O-MWCNTs, and some of them resided in the cytoplasm, while the morphology was not altered by O-MWCNTs. As the control, the pristine MWCNTs(p-MWCNTs) show higher cytotoxicity than O-MWCNTs, damaging cell viability and inducing cell apoptosis. All these toxicological data are of benefit to more wide applications of O-MWCNTs in the future.
