Metabolic reprogramming is a key characteristic of hepatocellular carcinoma， and abnormal fatty acid metabolism is closely associated with tumor immune escape. This article systematically reviews the molecular mechanisms of fatty acid metabolic reprogramming in hepatocellular carcinoma， focusing on key enzymes and their transcriptional regulatory networks within de novo lipogenesis and fatty acid oxidation pathways. This article also analyzes the metabolic heterogeneity between β-catenin-mutant hepatocellular carcinoma and AXIN1-mutant hepatocellular carcinoma and their therapeutic implications， summarizes the multidimensional mechanisms by which the lipid microenvironment regulates immune cell function， and reviews the targeted therapeutic strategies for different molecular subtypes of hepatocellular carcinoma.

After Hubert first reported cases of IgA nephropathy (IgAN) associated with inflammatory bowel disease (IBD) in 1984, researches further confirmed the association. Genome-wide association analyses also suggested that they may share a common genetic background. As IgAN is one of the leading causes of kidney failure and chronic kidney disease (CKD), early diagnosis and intervention can significantly improve the prognosis, and strengthening renal function follow-up and IgAN screening in IBD patients helps disease management. This article reviews the interplay between IBD and IgAN to provide reference for clinical diagnosis and treatment.

Objective:To study the immunotherapy effects of different doses of human peripheral blood γδT cells on human hepatoma cells (SMMC-7721) xenograft model.Methods: (1)The nude mouse model of liver cancer was established by inoculated BALB/c mouse subcutaneous with human hepatoma cell line (SMMC-7721).(2)The mononuclear cells in healthy human were extracted from peripheral blood,and specific amplification γδT cells in vitro.(3) The nude mouse model divided into 5 groups by random.The positive control group was 5-Fu,negative control group was normal saline(NS).The treatment group was injected different doses of γδT cells(1×105,5×105 and 25×105)by nude mice tail vein.The positive control group injected 5-Fu by enterocoelia,negative control group injected NS by tail veins.The inhibition effect of different dose γδT cells on tumor was observed,including weight,food intake and growth conditions,etc.and the changes of tumor volume (TV),relative tumor volume (RTV)and relative tumor appreciation rate[T/C(%)] were compared with positive control group and negative control group.Results: Different dose of γδT cells had different degree of inhibition on nude mouse xenograft growth.RTV compared with saline negative control group was statistically significant (P<0.05).Compared with the positive control group of 5-Fu,the TV growth was significantly lower than the 5-Fu,degree of inhibition was similar in RTV each dose group,and all slightly higher than the 5-Fu positive control group.The each dose group of T/C (%)was slightly lower than the relative tumor proliferation rate of the control group of 5-Fu,but had no significant difference.Conclusion: The γδT cells from peripheral blood had significant inhibitory effect on nude mice transplanted liver tumor and it may be used as a new treatment for liver cancer immunotherapy provide experimental data.

PURPOSE: The role of IL28B gene variants and expression in hepatitis B virus (HBV) infections are not well understood. Here, we evaluated whether IL28B gene expression and rs12979860 variations are associated with HBV outcomes. MATERIALS AND METHODS: IL28B genetic variations (rs12979860) were genotyped by pyrosequencing of DNA samples from 137 individuals with chronic HBV infection [50 inactive carriers (IC), 34 chronic hepatitis B (CHB), 27 cirrhosis, 26 hepatocellular carcinoma (HCC)], and 19 healthy controls. IL28A/B mRNA expression in peripheral blood mononuclear cells was determined by qRT-PCR, and serum IL28B protein was measured by ELISA. RESULTS: Patients with IL28B C/C genotype had greater IL28A/B mRNA expression and higher IL28B protein levels than C/T patients. Within the various disease stages, compared to IC and healthy controls, IL28B expression was reduced in the CHB, cirrhosis, and HCC cohorts (CHB vs. IC, p=0.02; cirrhosis vs. IC, p=0.01; HCC vs. IC, p=0.001; CHB vs. controls, p<0.01; cirrhosis vs. controls, p<0.01; HCC vs. controls, p<0.01). When stratified with respect to serum HBV markers in the IC and CHB cohorts, IL28B mRNA and protein levels were higher in HBeAg-positive than negative individuals (p=0.01). Logistic regression analysis revealed that factors associated with high IL28B protein levels were C/C versus C/T genotype [p=0.016, odds ratio (OR)=0.25, 95% confidence interval (CI)=0.08-0.78], high alanine aminotransferase values (p<0.001, OR=8.02, 95% CI=2.64-24.4), and the IC stage of HBV infection (p<0.001). CONCLUSION: Our data suggest that IL28B genetic variations may play an important role in long-term development of disease in chronic HBV infections.

ObjectiveA new style of artificial vessel scaffold was designed making the use of property of organoselenium catalyzing the releasing of Nitric oxide (NO). MethodsSelenium-containing catalyst organoselenium immobilized polyethyleneimine (SePEI) as polycation and polyglutamic acid (PGA) as polyanion were alternately coated onto the surface of polycaprolactone (PCL) nanofiber scaffolds obtained by electrospinning to form the blood vessel scaffold. Self-assembly was characterized by UV and atomic absorption qualitatively and quantitatively. Catalytic generation of NO from the NO donors- RSNOs was tested under the existence of reducing agent RSH. Biological properties were also evaluated. Results The NO release was relatively stable with no significant burst appeared, and still could be detected after 80 hours of catalyzing. The material was proved to show little cytotoxicity, and displayed significant effect in inhibiting of platelet aggregation through biological testing. Conclusion The new style of artificial vessel scaffold has good effect on improving the biological properties of materials.

BACKGROUNDTo investigate the efficacy of EP regimen combined with split-course hyperfractionated accelerated irradiation for locally advanced non-small cell lung cancer.

METHODSThe treatment was composed of 3 cycles of combined chemoradiotherapy at 4-week intervals. Chemotherapy with cisplatin ( 30 mg/m²) and etoposide (60 mg/m²) was administrated intravenously on days 1-3, followed by radiotherapy on days 4-8. A course of radiotherapy consisted of 1.5 Gy per fraction, twice a day (3 Gy per day) for 5 consecutive days, for a total dose of 15 Gy. In the third cycle, additional irradiotherapy consisted of 2 Gy once a day was performed on days 11-15, for a total dose up to 55 Gy during 10 weeks. After three cycles, patients were given 2 additional cycles of chemotherapy with MVP regimen.

RESULTSOf the 43 patients, 12 had a complete remission and 22 a partial response, resulting in an overall response rate of 79.1%. Of the 152 chemotherapeutic cycles administrated, there were 40 during which grade III-IV toxicities occurred, mainly consisting of leukopenia and vomiting. The 1- and 2-year survival rates were 66.7% and 57.2%, respectively.

CONCLUSIONSEP regimen combined with split-course hyperfractionated accelerated irradiation is effective and well tolerated for advanced locally non-small celll lung cancer. It should be investigated further.
