Angelica sinensis (AS, Danggui in Chinese) is an important herbal component of various traditional formulae for the management of asthenia and its tonic effects. Although AS has been shown to ameliorate cognitive damage and nerve toxicity in D-galactose (D-gal)-elicited senescent mice brain, its effects on liver and kidney injury have not yet been explored. In this work, mice were subjected to hypodermic injection with D-gal (200 mg/kg) and orally gavaged with AS (20, 40, or 80 mg/kg) once a day for 8 successive weeks. Results revealed that AS significantly improved liver and kidney function as assessed by organ index and functional parameters. In addition, AS pretreatment effectively ameliorated the histological deterioration. AS attenuated the MDA level and markedly enhanced the activities and gene expressions of antioxidative enzymes, namely Cu, Zn-SOD, CAT, and GPx. Furthermore, AS markedly inhibited the D-gal-mediated increment of expressions of inflammatory cytokines iNOS, COX-2, IκBα, p-IκBα, and p65 and promoted the IκBα expression level in both hepatic and renal tissues. In sum, AS pretreatment could effectively guard the liver and kidney of mice from D-gal-induced injury, and the underlying mechanism was deemed to be intimately related to attenuating oxidative response and inflammatory stress.

We aim to investigate the correlations of hypoxia inducible factor-1a (HIF-1a) C1772T (rs11549465) and G1790A (rs11549467) gene polymorphisms with digestive tract cancers. A sum of 267 digestive tract cancers patients were hospitalized in Taizhou Central Hospital of Zhejiang Province as case group between December 2012 and December 2014. Additionally, 275 healthy people who had a physical examination in our hospital at the same time were selected as control group. Polymerase chain reaction-restriction fragment length polymorphism was utilized for detecting allele and genotype frequency of different locus in case and control group. Meta-analysis was performed using Comprehensive Metaanalysis 2.0 (Biostat Inc., Englewood, New Jersey, USA). Our result showed statistical significance only exists in family history of cancer between case and control group (P\0.05). Both C1772T (rs11549465) and G1790A (rs11549467) polymorphisms showed positive correlations with an increasing risk of digestive tract cancers. The frequencies of TT genotype of C1772T (rs11549465) and GA, AA genotypes of G1790A (rs11549467) polymorphisms in case group were evidently higher compared with the controls (all P\0.05). Besides, the comparison of allele and dominant models of HIF-1a C1772T (rs11549465) and G1790A (rs11549467) between two groups showed a significant difference (all P\0.05). Meta-analysis results further confirmed that the onset risk of digestive tract cancers may be improved under allele and dominant models of HIF-1a C1772T (rs11549465) and G1790A (rs11549467) (all P\0.05). Single nucleotide polymorphisms of HIF-1a C1772T (rs11549465) and G1790A (rs11549467) may play a role in development of digestive tract cancers.

N-methyl-D-aspartate receptor 2B subunit (NR2B) has an important role in the development of conditioned place preference (CPP) and psychostimulant abuse. Rhynchophylline is presently used to treat central nervous systems diseases and has a non-competitive antagonistic effect on NMDA receptors. In this study, amphetamine was administered in rats (2 mg/kg, s.c., once each day for 4 consecutive days), during which they were treated with rhynchophylline (60 mg/kg, i.p., once each day for the next 3 days). NR2B mRNA and protein expression were examined by in situ hybridization and immunohistochemistry. CPP was induced by amphetamine (2 mg/kg, s.c.) by 4th day in rats. Rhynchophylline effectively reversed the expression of amphetamine-induced CPP and itself did not produce a CPP. Amphetamine-CPP rats showed a significantly increased NR2B mRNA and protein expression in medial prefrontal cortex and hippocampal CA1 areas as compared to the control group. Rhynchophylline reversed NR2B mRNA and protein levels induced by amphetamine but rhynchophylline by itself had no effect on NR2B expression in control rats. These results indicate that rhynchophylline inhibits the expression of amphetamine-induced rewarding effect, and this action might be related to down-regulation of NR2B expression in medial prefrontal cortex and hippocampal CA1 area.
