Neurodegenerative disease is characterized by progressive loss of neurons in specific brain regions that results in neuronal dysfunction of the central nervous system. Although the pathological mechanism is not fully established, the activation of glial cells mediated neuroinflammation appears to be involved. Heat shock protein 70 (HSP70) is originally described as intracellular chaperone, which plays an important role in protein quality control in cells. However, recent study showed that up-regulation of HSP70 had anti-inflammatory effects in the brain. HSP70 protected neurons from damage and improved neurological function by decreasing inflammatory response as indicated by inactivation of glial cells and inhibition of pro-inflammatory cytokine release. So it is of great significance to find new compounds targeting at HSP70 as neuroprotective agents to delay the progress of neurodegenerative disease. This review will focus on the role of HSP70 in neuroinflammation and the recent advances in using HSP70 as a target for the treatment of neurodegenerative disease.

Danshen is one of the traditional Chinese herbal medicines and nas a long history or being used clinically in the treatment of cardiovascular and cerebrovascular conditions such as coronary heart disease and angina pectoris. Tanshinone IIA is a derivative of phenanthrene-quinone isolated from Danshen. It has been reported to be the major bioactive compound of Danshen and has diverse biological effects. Recent studies demonstrated that tanshinone IIA had neuroprotective effects on experimental ischemic stroke through its antiinflammatory, anti-oxidant, anti-apoptosis effects and its inhibitory effect on excitatory amino acid toxicity. In this review, we summarized all the recent progresses on the protective effect of tanshinone IIA on cerebral ischemic stroke. Hopefully, this article will throw some light on further study and application of tanshinone IIA.

Sphingolipids, especially ceramide and S1P, are structural components of biological membranes and bioactive molecules which participate in diverse cellular activities such as cell division, differentiation, gene expression and apoptosis. Emerging evidence demonstrates the role of sphingolipids in hepatocellular death, which contributes to the progression of several liver diseases including ischaemia-reperfusion liver injury, steatohepatitis or hepatocarcinogenesis. Furthermore, some data indicate that the accumulation of some sphingolipids contributes to the hepatic dysfunctions. Hence, understanding of sphingolipid may open up a novel therapeutic avenue to liver diseases. This review focuses on the progress in the sphingolipid metabolic pathway with a focus on hepatic diseases and drugs targeting the sphingolipid pathway.

The aim of this study is to investigate the protective effect of N-[2-(4-hydroxyphenyl)ethyl]-2-(2, 5-dimethoxyphenyl)-3-(3-methoxy-4-hydroxyphenyl)acrylamide (FLZ), a novel synthetic squamosamide cyclic derivative, against Parkinson's disease (PD) model mice induced by the inflammatory bacterial endotoxin, lipopolysaccharides (LPS) and the neurotoxin 1-methy-4-phenyl-1, 2, 3, 6-tetrahydropyridine (MPTP). C57/BL mice were ip injected LPS (5 mg x kg(-1)) once. One week following the LPS injection, mice received a subcutaneous injection of MPTP (25 mg x kg(-1)) once daily for 2 days. Eight weeks later, FLZ (25, 50 and 75 mg x kg(-1)) was orally administered to mice once daily for 60 days. The motor ability of the mice was evaluated by rod climbing test and footprint test. The dopamine (DA) levels in mouse striatum were determined by high performance liquid chromatography system. The tyrosine hydroxylase (TH)-positive cells were showed by immunohistochemical analysis. FLZ treatment significantly improved motor dysfunction of mice challenged by LPS plus MPTP. The increase of TH-positive cell numbers and elevation of DA levels may be contributed to the beneficial effects of FLZ on motor behavior. This study showed FLZ has significant therapeutic effect on LPS plus MPTP induced chronic PD model, which indicates its potential as a new candidate drug to treat PD.

Objective To observe effects of acupuncture on different traditional Chinese medicine(TCM) syndrome types in patients with apoplectic hemiplegia.Methods 57 cases of apoplectic hemiplegia were divided into the Qi deficiency with blood stagnation group(35 cases) and blockage of the meridians and collaterals by phlegm and blood group(22 cases).All patients were treated by scalp acupuncture combined with body acupuncture.The clinical therapeutic effect was evaluated according to the scores of manner,speech,motor function of limbs,and so on.Results In the Qi deficiency and blood stagnation group,2 cases were basically cured,17 were remarkably effective,12 were effective,with a total effective rate of 88.6%;while,in the blockage of the meridians and collaterals by phlegm and blood group,3 cases were basically cured,14 were remarkably effective,3 were effective,with a total effective rate of 90.9%.There was a significant difference between the two groups in clinical remarkably effective rate(P<0.01),but no difference in total effective rate( P>0.05).Conclusion Acupuncture can obviously improve the consciousness,language and limb function of patients with apoplectic hemiplegia.The effective rate of type of blockage of the meridians and collaterals by phlegm and blood is superior to type of Qi deficiency with blood stagnation.

Aim To investigate the anti-neuroinflam-matory activities of dehydromiltirone and the underlying mechanisms in LPS-stimulated microglial cell line BV2 cells. Methods BV2 cells were pre-treated with de-hydromiltirone, then stimulated by LPS. The levels of nitric oxide( NO) were measured by Griess assay, and the concentrations of pro-inflammatory cytokines were measured by ELISA assay. Confocal fluorescence mi-croscopy was used to measure the expression of MAC-1, the biomarker of activated BV2 cells. The levels of-inducible nitric oxide synthase ( iNOS ) , cyclooxygen-ase-2 ( COX-2 ) , NF-κB and PI3 K/Akt were deter-mined by Western blot analysis. Results The treat-ment of dehydromiltirone significantly inhibited the pro-duction of NO, TNF-α and IL-6, attenuated the ex-pression of iNOS and COX-2 protein, and dampened the microglial activation in LPS-stimulated BV2 cells. The mechanistic study revealed that dehydromiltirone inhibited the phosphorylation of PI3 K and Akt in LPS-stimulated BV2 cells, and decreased NF-κB activation by suppressing the degradation of IκB. Conclusion dehydromiltirone shows significant anti-neuroinflamma-tory effects through inhibiting PI3 K/Akt phosphoryla-tion and then inhibiting NF-κB signaling pathway.
