Objective:To Compare the two-dimensional gel electrophoresis(2D-PAGE)with cerebrospinal fluid(CSF)of Parkinson’s disease patients and control group(patients with headache),and to find out the disease-specific proteins(DSPs)which are closely correlated with Parkinson’s Disease. Methods:proteins extracted from CSF were run in immobilized pH gradient isoelectic focusing(IPG-IEF)at the first dimension,and then run in vertical flat sodium dodecyl sulphate polyacrylamide gel electrophoresis(SDS-PA GE)at the second dimension. The protein spots in gels were visualized by silver staining protocol followed by gel scanning and analysised by Pdquest 8.0 software.Then differentially displayed protein spots were searched and identifiyed by MALDI-TOF-MS.Results:Three DSPs were found and they were Protein-tyrosine phosphatase 1B,Apolipoprotein E and E3 ubiquitin-protein ligase. Conclusion:There were different protein expressing in 2D-PAGE of Parkinson’s disease and control group.These proteins may be the DSPs of Parkinson’s disease and may be taked as biomarkers of Parkinson’s disease.

Objective To investigate the correlation between S100B protein and the stability of carotid artery arteriosclero‐sis .Methods A total of 200 patients with carotid artery arteriosclerosis(CAS) were assigned as study group ,and then subdivided into stable plaques (SP)group and instable plaques (IP)group ,and 198 whoes age and gender well matched unrelated healthy sub‐jects were enrolled as control group .The levels of S100B and hs‐CRP of the 3 groups were measured by ELESA .All the diagnosis were confirmed by color Doppler and B‐ultrasound .Results The level of serum S100B was significantly higher in IP group than that of SP group and control group(P<0 .01) .There was no statistical significance between IP and SP group in the level of serum S100B(P=0 .07) .The level of hs‐CRP was significantly higher in IP group than that of SP group and control group(P<0 .01) . There was no statistical significance between IP and SP group in the level of serum hs‐CRP(P=0 .59) .Conclusion The increase of serum level of S100B in the IP CAS patients shows that S100B may take part in the pathogenic mechanism of CAS ,and regulating of S100B may become the potential therapeutic targets for CAS .

[Summary] Vocal cord movement disorders may lead to hoarseness,dysphonia or even dyspnea.They reduce the quality of speech,destroy social communications,or even are life-threatening.For patients with vocal cord movement disorders which are not sensitive to the treatment of phonation training or medication,surgical procedures can improve the quality of phonation.At present, with operation methods for vocal fold movement disorders developing rapidly,types of the operations are exploring,while at the same time the situations of confusion or repetition of operation methods and terminologies increase.On this condition,we summarized different types of surgeries for vocal cord movement disorders by reviewing relevant literatures.

Objective To observe the clinical efficacy of acupuncture with elongate needle plus red light radiation in treating post-herpetic neuralgia.Method Seventy patients with post-herpetic neuralgia were randomized into a treatment group and a control group, 35 cases in each group. The treatment group was intervened by acupuncture with elongate needle plus red light radiation, while the control group was by orally taking Pregabalin capsules. Visual Analogue Scale (VAS) and Quality of Life (QOL) were observed before and after intervention, and the clinical efficacies were compared between the two groups.Result The total effective rate was 97.1% in the treatment group, versus 71.4% in the control group, and the difference was statistically significant (P<0.05). After treatment, VAS and QOL scores were significantly changed in both groups (P<0.05). The VAS and QOL scores in the treatment group were significantly different from that in the control group after treatment (P<0.05).Conclusion Acupuncture with elongate needle plus red light radiation is effective in relieving post-herpetic neuralgia.

Objective: To investigate the effect of silver nanoparticles (AgNPs) on hemichannel activity in human skin keratinocytes (HaCaT) and to explore the role of hemichannel in AgNP-induced anti-proliferative effect on HaCaT cells.Methods: HaCaT cells were exposed to 0, 0.1, 0.2, 1.0, 5.0, 10.0, 15.0 and 20.0 μg/cm2 of AgNPs for 24 h and cell viability was assessed by propidium iodide (PI) staining with flow cytometry.Hemichannel activity was examined by ethidium bromide (EB) uptake experiments in cells exposed to AgNPs with and without hemichannel inhibitor carbenoxolone (CBX).Afterward, HaCaT cells were seeded at a low density of 1×104cell /cm2 or a normal density of 4×104cell /cm2 and cultured for 24 h.Cell proliferation was measured by cell counting kit-8 (cck-8) in low-or normal-density cultured cells exposed to AgNPs for 24 h with and without 100 μmol/L CBX.Results: Cell viability showed no significant differences between the control and AgNP-exposed groups with the concentration less than 10 μg/cm2.Exposure to AgNPs increased EB uptake in a time-and dose-dependent manner in HaCaT cells and EB fluoresce density was increased to 116.67%, 124.85% and 139.53% of the control after exposure to 10 μg/cm2 AgNPs for 2 h, 12 h and 24 h.After being treated with 25, 50 and 100 μmol/L CBX, 10 μg/cm2 AgNP-induced increase in EB uptake was significantly reduced in HaCaT cells (P<0.01).The cellular proliferation rate was increased inlow-and normal-density cultured cells after AgNPs exposure with 100 μmol/L CBX.After being treated with 100 μmol/L CBX, 10 μg/cm2 AgNP-induced anti-proliferation in low-density cultured cells was significantly restrained (P<0.01).Conclusion: AgNPs could enhance hemichannel activity of HaCaT cells.Hemichannel activation was involved in AgNP-induced anti-proliferative effect.

Objective To investigate the serum neuron-specific enolase (NSE) and high sensitivity C-reactive protein (hs-CRP) on neonatal hypoxic-ischemic encephalopathy (HIE) in children with illness and prognosis of assessed value. Method The serum NSE, hs-CRP levels of 40 patients with HIE (HIE group) of the acute stage and convalescence, and 20 healthy neonates (control group ) were measured and the clinical sub-degree relationships were analyzed. Results The serum NSE, hs-CRP levels in HIE group of the acute stage [ (32.88 ± 12.61 ) μ g/L, (6.43 ± 2.07) mg/L] were significantly higher than those in control group [(8.62 ± 3.58) μ g/L, (2.61 ± 0.95) mg/L](P ＜ 0.01 ). The serum NSE, hs-CRP levels in HIE group of the severe acute stage were significantly higher than those of the mild and light acute stage (P＜0.01 ). The more severe disease, the more higher NSE, hs-CRP. Conclusion The serum NSE, hs-CRP reflect the brain neuronal damage or necrosis of the objective indicators that could be used as early objective indicators to judge the pathogenetic condition and prognosis of HIE.
