The niacin flush negative rates of the three groups were comparedChi-square test. Results · Compared with HC group, the niacin skin flush of CHR group and FES group reduced at different concentrations and time points. MANOVA showed a significant main group effect of niacin skin flush (F1.746, P0.009). There were no significant group × concentration interaction (F1.628, P0.138) and group × time interaction (F0.851, P0.531). Compared with HC group, the niacin total flush scores of CHR group were lower (t-2.697, P0.008). The significant differences of the proportion of patients with negative niacin reaction among the three groups were found for the concentration of 0.1 mol/L at 5 min (χ216.709, P0.000) and 0.001 mol/L at 20 min (χ26.380, P0.041).

Methods · SH-SY5Y cells treated with H2O2 were chosen as cell models of oxidative stress. Cell viability was determined using cell counting kit-8 (CCK-8). The mRNA levels of BDNF and its important transcripts were detectedquantitative real-time PCR (qPCR). The histone deacetylases (HDACs) activity fluorescence quantification assay kit was used to measure the effect of ZMS on HDACs activity. Western blotting was used to detect the protein levels of acetylated histone H3, acetylated histone H4, specific acetylation site-related proteins, and HDAC1/2/3. Results · qPCR showed that ZMS could increase the mRNA levels of BDNF and its transcript Ⅳ in the cell models. Western blotting showed that ZMS pretreatment could increase the protein levels of acetylated histone H3, acetylated histone H4 and acetylated histone H3K14, and there was no significant effect on protein levels of HDAC1/2/3. In addition, HDACs activity fluorescence quantification assay kit showed that ZMS could inhibit HDACs activity significantly.

Modulating neural circuits in substance addiction with repetitive transcranial magnetic stimulation XU Xiao-min, CHEN Tian-zhen, JIANG Hai-feng 2019, 39 (6):  655.  doi: 10.3969/j.issn.1674-8115.2019.06.015 Abstract ( 767 )   PDF (10362KB) ( 368 )   Substance addiction is a chronic and recurrent disorder and may be related to complex neural circuits. However, there is no optimally effective treatment for substance addiction currently. Repetitive transcranial magnetic stimulation (rTMS) is a non-invasive, safe and easy-to-operate neuroelectrophysiological technique, which is becoming an emerging therapeutic option for many mental disorders. The effect of rTMS on substance addiction is closely related to the stimulation of neural circuits. However, the mechanism is still unknown. The review summarizes recent research progress on the application of rTMS and its application combined with other therapies in substance addiction, as well as the regulation of rTMS on substance addiction-related neural circuits.

Role of farnesol X receptor in glycolipid metabolism regulation ZHAO Ming-liang1, 2, ZHAO Ai-hua1, ZHENG Xiao-jiao1, JIA Wei1 2019, 39 (6):  671.  doi: 10.3969/j.issn.1674-8115.2019.06.018 Abstract ( 821 )   PDF (11737KB) ( 314 )   Farnesol X receptor (FXR), also known as bile acid nuclear receptor, is a ligand-dependent nuclear transcription factor distributed in multiple tissues and organs such as liver and intestinal tract. And bile acid is its endogenous natural ligand. Recent studies have shown that intestinal FXR plays an indispensable role in glycolipid metabolism regulation, and intestinal specific FXR agonists or antagonists can participate in glucose and lipid metabolism regulation in vivo. In this paper, the role of intestinal FXR in glycolipid metabolism reported in recent years is systematically reviewed. Related Articles | Metrics

Alterations in bile acid levels in metabolic diseases and related treatment strategies KUANG Jun-liang, ZHENG Xiao-jiao, ZHAO Ai-hua, JIA Wei 2019, 39 (6):  678.  doi: 10.3969/j.issn.1674-8115.2019.06.019 Abstract ( 847 )   PDF (9738KB) ( 447 )   Bile acid as a signaling molecule can specifically bind to bile acid receptors (such as farnesoid X receptor and G-protein-coupled bile acid receptor) to mediate a series of biological regulation reactions. In recent years, it has been found that bile acids are widely involved in glucose metabolism, lipid metabolism and energy metabolism. The development of metabolic diseases is usually accompaniedthe changes of bile acid profiles and receptors, and thus bile acids may be applied as potential biomarkers for clinical diagnosis, prediction, and evaluation of therapeutic effects. This article reviews the relationship between bile acids and metabolic diseases, and the treatment of metabolic diseases based on the regulation of bile acid metabolism. Related Articles | Metrics

Research progress of secreted protein acidic and rich in cysteine in glaucoma filtering bleb scarring LUO Li-ying, WU Jia-hui, XIANG Xiao-qiong, TANG Min, FU Yang 2019, 39 (6):  684.  doi: 10.3969/j.issn.1674-8115.2019.06.020 Abstract ( 858 )   PDF (6890KB) ( 350 )   Filtering bleb scarring is the main caof glaucoma filtration surgery failure. Subconjunctival injection of antimetabolites, such as mitomycin and 5-fluorouracil, is widely used clinically to reduce the incidence of scarring, which improves the success rate of the surgery. However, accompanied side effects such as cytotoxicity should not be ignored. Secreted protein acidic and rich in cysteine (SPARC) as a matricellular protein is widely distributed in the eyes, which plays an important role in the process of wound repairing and tissue remodeling. The of SPARC is significantly elevated in the momodel of subconjunctival scarring. Researches suggest that SPARC participates in and regulate the formation of bleb scarring through multiple pathways, therefore it may become a specific new target in the anti-scarring therapy.
