OBJECTIVE To investigate the protective effects of hydrogen peroxide preconditioning (HPP) on the pheochromocytoma (PC12) cells treated with 1-methyl-4-phenylpyridinium (MPP(+)) and to explore the potential mechanisms. METHODS The viability and apoptosis of PC12 cells were determined by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT)(More)
MicroRNAs (miRNAs) play an important role in the development, differentiation, proliferation, survival, and oncogenesis of cells and organisms including nervous system. However, the role of miRNAs in primary neurons of dorsal root ganglion (DRG) after injury was not clear. In this study, a miRNA microarray analysis was performed, and a total of 21 miRNAs(More)
Hereditary spinocerebellar ataxia (SCA) is a devastating, incurable disease. Stem-cell-based therapies represent new promise for clinical research in neurology. The objectives of this study were to assess the feasibility, efficacy, and potential toxicity of human umbilical cord mesenchymal stem cells (UCMSCs) therapy in patients with SCA. Sixteen(More)
The purpose of this study was to look for alterations in β-amyloid peptide (Aβ) metabolism-related molecules in predementia, the early stage of Alzheimer’s disease (AD). AlCl3 (Al) and d-galactose (D-gal) were used to induce the mouse model for predementia and AD. Protein expression of β-amyloid (Aβ), β-secretase (BACE1), neprilysin (NEP), insulin degrading(More)
OBJECTIVE To investigate the relationship of four single nucleotide polymorphism (SNP) haplotypes in the angiotensinogen (AGT) gene to the primary hypertension with or without cerebral infarction in the Li nationality of Hainan, China. METHODS Total 300 subjects were allocated into three different groups: Group 1, 100 patients who have primary(More)
OBJECTIVE To investigate the neuroprotective effects of simvastatin on lipopolysaccharide (LPS)-induced rat model of Parkinson's disease (PD) and the mechanisms involved. METHODS Hemiparkinsonian rat models were induced by stereotaxieal injection of LPS in the right substantia nigra compacta. After 2 weeks of simvastatin treatment, rotational behavior(More)
Micrometam C is a core of novel marine compound isolated from the mangrove associates Micromelum falcatum. In this study, we investigated the protective effects of micrometam C in inflammation models in the transgenic zebrafish line Tg (corola: eGFP) and RAW264.7 macrophages. We found that micrometam C significantly suppressed the migration of immune cells(More)
PURPOSE This retrospective study evaluates the efficacy and safety of S-1 chemotherapy for recurrent and metastatic nasopharyngeal carcinoma patients after failure of platinum-based chemotherapy. PATIENTS AND METHODS Thirty-nine patients with recurrent and metastatic nasopharyngeal carcinoma who failed previous platinum-based chemotherapy received oral(More)
