To investigate the effect of C/EBP βon the neuroinflammation.Recently,neuroinflamma-tion research mainly focused on C/EBP β,more and more researches indicated that C/EBP βmay play an important role in neurodegenerative diseases.We searched the published papers in PubMed,CNKI,and Wan Fang date bases in June 2015.The key words were used asCCAAT enhancer binding protein beta,Neu-ron,Neuroinflammationand so on.According to the inclusion and exclusion criteria, we summaried and analyzed the literatures.Eventually,42 articles were adapted,most of which were foused on the functions and mechanisms of C/EBP βin neuroinflammation.C/EBP βparticipate in multiple signaling pathways of neu-roinflammation,and the regulation mechanism is complicated.Abrogation of C/EBPβexpression or its down-regulation by gene regulation may may serve as a therapeutic target to attenuate deleterious effects in neural tissue and ultimately prevent the development of neurodegenerative disorders.

Objective To identify the effect of blood pool 18F-FDG activity on liver SUV and to investigate the optimal normalization method.Methods PET/CT and common serological examination items from 1 018 subjects were retrospectively collected.Mean SUV of liver and blood were recorded as SUVmean(L) and SUVmean (B),respectively.The difference and quotient of SUVmean(L) and SUV mean (B) were calculated as SUVmean (L-B) and SUVmean (L/B),respectively.CV of SUVmean (L),SUVmean (L-B) and SUVmean(L/B) were calculated to assess their inter-individual variations.Pearson correlation analysis was used to evaluate the relationship of SUVmean(L),SUVmean(L-B),SUVmean(L/B) with SUVmean(B).Multiple linear stepwise regression was performed to identify their vulnerability to common serological examination items.Results CV of SUVmean(L/B) (15.1%) was less than that of SUmean(L) (23.2%) and SUVmean(L-B) (40.6%).Correlation between SUVmean(L) and SUVmean(B) (r =0.820,P<0.001) was more significant than that between SUVmean(L-B) and SUVmean(B) (r =0.205,P<0.001) as well as between SUVmean (L/B) and SUVmean (B) (r=-0.376,P<0.001).Blood glucose and BMI correlated with SUVmean(L) and SUVmean(L/B),but not with SUV (B).Age and HDL correlated with SUVmean(L) and SUVmean(B),but not with SUV (L/B).Fatty liver was significantly associated with SUV mean (L/B) (β =-0.047,P <0.001),but not with SUVmean(L) and SUVmean (B).Conclusions 18 F-FDG activity of blood pool affects liver SUV.SUV mean (L/B) is a simple and reliable normalization method since its inter-individual variation and vulnerability to common serological examination items are relatively lower than liver SUV.

Tumor cells leads to enhanced glucose uptake and the conversion of a larger fraction of pyruvate into lactate even under the circumstance of abundant oxygen. This phenomenon of aerobic glycolysis is known as the Warburg effect. Lactic acid, as an important tool for tumor cells to modify the tumor microenvironment, promotes the process of tumor invasion and metastasis, and contributes to tumor development by inducing and recruiting immunosuppression-related cells and molecules. Lactic acid could efflux out of the cancer cells

As an essential amino acid, tryptophan (Trp) has various physiological functions and is of great significance in the metabolic process of tumors. In the human body, tryptophan is mainly transformed through kynurenine metabolic pathway, which not only promotes the inherent malignant properties of tumor cells, but also leads to immune-suppressive tumor microenvironment. Changes in tryptophan metabolism often occur in tumors, accompanied by abnormal gene expression of tryptophan-related enzymes, among which indoleamine 2,3-bioxygenase (IDO)-related gene expression and tryptophan 2,3-dioxygenase (TDO)-related gene changes are the most significant. A large number of clinical trials on IDO inhibitors, TDO inhibitors and combination therapy have been carried out. This paper reviewed the tryptophan metabolic pathway, regulation of IDO (TDO), kynurenine (KYN) and other related genes in tumor cells, and outlined the development of therapeutic schedule targeting tryptophan-related genes. The new progress provides new ideas for the further exploration of tumor treatment options.
