Role of Cytoglobin in Ferroptosis Regulation / 中国生物化学与分子生物学报

Ferroptosis is a recently reported iron-dependent cell death, which is induced by the broken of cellular redox homeostasis and characterized by high level of lipid peroxide. More and more studies have indicated the importance of ferroptosis during disease development and prevention. As a member of globin family, cytoglobin (CYGB), also known as stellate cell activating protein (STAP), can bind to oxygen for its transportation. Moreover, CYGB contains two cysteins within its amino acid sequence and could form the S-S bond when there has change of cellular redox which will result in downstream signaling alternation. Furthermore, CYGB has nitric oxygen dioxygenase activity to scavenge excessive nitric oxygen and prevent the production of ONOO

Cerebral infarction complicated with multiple arterial thrombosis caused by cystathionine beta-synthase gene mutation in youth: a case report / 中华神经科杂志

Hyperhomocysteinemia (HHcy) is one of the independent risk factors for youth cerebral infarction. Gene mutation of key enzymes in homocysteine metabolism is the main cause of HHcy. Few cases of cystathionine beta-synthase (CBS) compound heterozygous mutation complicated with pulmonary embolism and lower extremity artery embolism have been reported. This article reported a young cerebral infarction patient complicated with pulmonary embolism and lower extremity artery embolism, who was subsequently detected with significantly elevated blood Hcy, and finally etiologically diagnosed with CBS 833 T>C/1082C>T compound heterozygous mutation. With the treatment of folic acid, methyl cobalt amine, vitamin B 6 and anticoagulant, the blood Hcy has been gradually declined, and no new thrombotic events occurred during the follow-up period of a year.

Effects of astragalus polysaccharide on depressive behaviors and hippocampal Nrf2-ARE signaling pathway in rats / 中国药理学通报

Aim To investigate the effects of astragalus polysaccharide (APS) on depressive behaviors, hippocampal damage and Nrf2-ARE signaling pathway in rats. Methods Wistar rats were randomly divided into control group, depression group, APS low dose group and APS high dose group. Rats (except the control group) underwent chronic unpredictable mild stress (CUMS) for 28 days. The depressive behaviors were assessed by tail suspension test, forced swim test and sucrose preference test. The histopathological changes of the hippocampus were valuated by HE staining. Levels of nuclear factor erythroid 2-related factor 2 (Nrf2) protein and Nrf2 mRNA were measured. The hippocampal levels of oxidative stress were evaluated. Results Compared with the control group, the depression group showed significant depressive behaviors and hippocampal damage. The depression group had higher levels of Nrf2 and MDA, but lower levels of HO-1, SOD, CAT and GSH-Px than the control group. However, APS does-dependently attenuated the hippocampal damage and depressive behaviors, increased hippocampal levels of Nrf2, HO-1, SOD, CAT and GSH-Px, but decreased hippocampal levels of MDA in rats. Conclusions APS can attenuate CUMS-induced hippocampal damage and depressive behaviors in rats, and the effects may be associated with the activation of Nrf2-ARE signaling pathway.

Recent advance in small nerve fiber impairment in Guillain-Barre syndrome / 中华神经医学杂志

Small nerve fibers refer to peripheral afferent small diameter, thinly myelinated Aδ-fibers and unmyelinated C-fibers. Small nerve fiber impairment caused by various mechanisms calls small fiber neuropathy (SFN). Small nerve fiber impairment caused by immune injury in Guillain-Barre Syndrome (GBS) is a common cause of SFN, which is currently reported as a variant of GBS; the main manifestations of small nerve fiber impairment of GBS are sense disturbance to pain and temperature and autonomic nerve dysfunction. Small nerve fiber impairment of GBS is widely correlated with the prognosis and mortality of GBS. At present, researches on small nerve fiber impairment of GBS are mainly based on case reports, and its diagnosis mainly relies on pathological examination and electrophysiological examination, which is easy to be missed in the early stage. Early recognition and appropriate management of small nerve fiber impairment of GBS are keys to reduce GBS mortality. In this paper, the pathogenesis, clinical manifestations, diagnosis, treatment and other aspects of small nerve fiber impairment of GBS are reviewed to provide clinicians with a comprehensive understanding of small nerve fiber impairment of GBS.

Effects of astragalus polysaccharide on hippocampal NF-κB signaling in rats with depressive behaviors / 中国药理学通报

Aim To investigate the effects of astragalus polysaccharide ( APS ) on depressive behaviors and hippocampal NF-κB signaling in rats with depression. Methods Wistar rats were randomly divided into con-trol group, depressive group, APS-low (200 mg·kg-1 ·d-1 ) group and APS-high ( 400 mg · kg-1 · d-1 ) group. Depressive behaviors were induced by chronic unpredictable mild stress ( CUMS) in rats. After trea-ted with APS, depressive behaviors were valuated by open field test, forced swim test and sucrose preference test. Levels of NF-κB p65, phosphorylated NF-κB p65 ( p-NF-κB p65 ) , phosphorylated IκBα ( p-IκBα) , NF-κB p65 DNA binding activity, TNF-α, IL-1β and IL-6 were measured to assess the activity of NF-κB sig-naling pathways. Results Compared to control group, rats in depressive group had less sucrose intake in su-crose preference and longer immobility time in forced swim test, as well as increased hippocampal NF-κB signaling activity. However, APS treatment dose-de-pendently alleviated depressive-like behaviors and in-hibited the activation of NF-κB signaling induced by UCMS. Conclusion The antidepressant effects of APS might be associated with the inhibition of hipp-ocampal NF-κB signaling pathway.

Effect of ethanol extracts from Polygonum multiflorum Thunb on expressions of signal pathway TLR4/TRIF/IRF-3 in LPS induced rats liver / 国际药学研究杂志

Objective To research the toxicity of ethanol extracts from Poylgonum multiflorum Thunb (PMT) induced by endotoxin of Gram-negative bacteria lipopolysaccharide (LPS) in rat liver, and then investigate the hepatotoxicity mechanisms of PMT on immune inflammatory signal pathway Toll-Like receptor 4 (TLR4) -interferon regulated factor3 (IRF-3). Methods SD rats were randomly assigned into normal control, LPS (4 mg/kg), acetaminophen APAP (625 mg/kg), PMT 6 g/kg (PMT- L), PMT 12 g/kg (PMT-H), LPS+APAP and LPS+PMT-L/-H groups. The 4 groups later were injected LPS 4 mg/kg by caudal vein, after 2 h, the corresponding drugs were administered once a day for 7 consecutive days, respectively. The changes of weight of rats were observed every day. The tissue morphology of liver tissue of rats on 2 h, 14 h, 5 d, 8 d after administration were detected by hematoxylin-eosin staining respectively. Real time quantitative PCR (RT-qPCR) method and Western blotting were used to detect the expression of TLR4, TRIF and IRF3 in the TLR4 signaling pathway in liver cells. Results Two hours after the rat tail vein injection of LPS, the liver tiny granulomas of rats could be observed in LPS-induced groups, and then, the liver injury of rats in LPS group was gradually recovered. Eight Days after LPS induction, the liver tissue structure of rats in LPS group was clear and complete, but in LPS + APAP group and LPS + PMT 6 or 12 g/kg groups, the focal necrosis of hepatocytes, with inflammatory cell infiltration could be observed. The results of RT-qPCR and Western blotting showed that in oral administration of PMT groups, the expression of TLR4, TRIF and IRF-3 mRNA and protein in the liver cells had no significant change compared with the normal control group. But in 4 groups induced with LPS, the expression of TLR4, TRIF and IRF- 3 mRNA and protein in the liver cells were significantly higher than that of the normal control group and LPS group (P<0.05). Conclusion PMT can cause liver damage induced by LPS, the hepatotoxicity is related to the positive regulation of TLR4/IRF-3 signaling pathways, which is not related to the dosage of PMT. The results show that activating TLR4/IRF3 signaling pathway is one of the mechanisms of liver injury of PMT in rats induced by LPS.
