Parkinson disease(PD)is a common,progressive and disabling neurodegenerative movement disorder. Diagnosis of PD depends on clinical history and physical examination,but misdi?agnosis is common in early stages because of similar symptoms to other movement disorders. which is why biomarkers are urgently needed to accurately diagnose PD,especially in the early stages of PD, and find new drug targets. This review discusses the curient research of the PD candidate biomarkers from cerebrospinal fluid and blood in terms of PD pathogenesis. We have found that dihy?droxyphenylacetic acid,alpha- synuclein and its related proteins in Lewy bodies,8- hydroxy deoxy?guanosine,uric acid,interleukin and neurotrophic factors are potential biomarkers. They participate in different stages of PD. In order to enhance the accuracy of early diagnosis and efficacy of drugs evalua?tion,we are to use multiple biomarkers rather than a single biomarker,in combination with different biologic pathways of biomarkers,neuroimaging as well as clinical symptoms.

Objective To propose new policies and strategies that will optimize the transformation of medical research achievements at hospital level.Methods In this paper,we systematically analyzed the characteristics and influencing factors of the transformation of medical research achievements based on the status quo in our hospital.Results In our hospital as an example,major problems in the transformation of medical research achievements identified as low investment,low conversion rate,complex procedures,multi-links existed and more multi disciplinary cooperation needed.Conclusions The hospital can take some measurements to optimize the transformation of medical research achievements,such as more stream lined management of scientific research project,establishing and improve the platform for scientific research transfer,increasing the funding,strengthening cooperation among different disciplinaries,building a professional team to promote the transfer and so on.

Objective To obtain the gene coding for the group 5 allergens from Dermatophagoides farinae ( Derf5 ) and predict its molecular characteristics. Methods The total RNA of D. farinae were extracted, and the gene Derf5 was amplified by RT-PCR with the primers designed according to previous sequence published in GenBank. The target gene was linked into pMD19-T Simple plasmid, sequenced and analyzed by bioinformatics software. Results The sequence homology reached to 97.8% between our sequenced result with one complete open reading fragment (ORF) and the reference. The gene encode an extracellular hydrophobic protein with 132 amino acid resides, one signal peptide from 1 to 19 position and one transmembrane domain from 1 to 19 position. The secondary structure was composed of extended strand (1. 52% ), random coil (7.58%) and alpha helix (90.91%). The encoded protein was deduced to have two Casein kinase Ⅱ phosphorylation sites. The similarity of the amino acid sequence of the group 5 allergens were 78% between D. farinae and D. pteronyssinus. Conclusion The gene Derf5 was cloned successfully, and its characteristics was primarily predicted.

The research capacity of a hospital has become an important criteria for hospital evaluation, Research activity and capacity in the hospital plays an important role in improvement of clinical care for patients.A tumor Hospital in Tianjin, has taken a full academic advantages and strengthen,providing strong support in research funding;standardizing the management on research outcome, and emphasize on translation of clinical research in recent years.We have explored the effective management model in scientific research activity.

Objective To explore the effect of transtheoretical model-based(TTM) health education on the self-management of the patients with chronic obstructive pulmonary disease.Methods 100 patients of COPD were divided into the experimental group and the control group randomly,50 cases in each group.The patients in the control group received routine health education,while the patients in the experimental group received TTM education.All the patients were investigated with the self-management scale at baseline and 4,12 and 24 weeks after discharge.Results After the intervention,the scores of self-management in the experimental group were significantly higher than those in the control group,the difference was statistically significant.Conclusions TTM health education can improve the self-management skills in patients with COPD.

Objective To explore the efficacy of the case and scenario teaching method in the neurosurgery practice teaching.Methods By cluster sampling,153 nursing students underwent rotary practice in neurosurgery department in People's Hospital of Three Gorges University from September 2011 to July 2012 were trained with the case and scenario teaching method.Scenario simulation training combined with case playback teaching was used in practice teaching.At the end of the internship,nursing students' satisfaction was investigated and their operational capacity was evaluated.Self-designed questionnaire was adopted to evaluate satisfaction.Operational capacity evaluation scores of nursing students were divided into several parts:basic operation examination (30％),specialized operation (30％),professional theory (30％) and teacher evaluation (10％).Data were analyzed using Excel spreadsheet for entry.Countif and Count function formula were used to calculate eligibility and the passing rate.Results Nursing students had high evaluation on case playback teaching methods.By this method,153(100％) nursing students considered that the learning initiative was improved.At the end of the internship,passing rates of basic operation examination,specialized operation,professional theory were 98.69％ (151/153),96.73 ％ (148/153) and 100％ while the total passing rate was 100％.Conclusion The case and scenario teaching method could develop the study positivity and practice ability of nursing students and can enhance the internship efficacy.

Objective To investigate the short term efficacy of transcatheter arterial chemoembolization(TA-CE)combined with arsenic trioxide(AS203) in the treatment of primary liver cancer.Methods 91 patients with advanced primary liver cancer underwent routine hepatic arterial chemoembolization,repeated every 4 weeks for 2 to 3 cycles.In each cycle of chemoembolization,AS2O3 ,was injected intravenously once a day for 2 weeks at a dose of 10～15mg.Results All patients completed 2～3 cycles treatment and followed for more than one year.Total response rate was 61.7% and clinical benefit rate was 42 cases of partial response(PR) ,35 cases of no changes(NC) and 11 cases of progressive disease(PD).Quality of life improved in 61 cases and stabilized in 24 cases.Toxicifies was mild and tolerable.Conclusion TACE combined with arsenic trioxide in the treatment of primary liver cancer is efficient with a mild toxicities.

Objective To evaluate the value of volumetric brain MRI in multiple system atrophy.Methods Eleven patients diagnosed as multiple system atrophy were recruited,includin 5 parkinsonism dominant(MSA-P)and 6 cerebellar dominant(MSA-C).9 patients with parkinsonism of other types and 6 healthy persons were set as case control and healthy control,respectively.T1 weighted (T1W)sagittal and axial images and T2-weighted(T2W)axial images were obtained from all patients and controls at 3.0T scanner.Diameters of the brain structures were measured infratentorially(brainstem, middle cerebellar peduncles(MCP),dentate and red neelus)and supratentorially(globns pallidus and putamen).Results The transverse diameter of the pons was significantly smaller in MSA patients than in the case and healthy controls((27.6?2.0)mm and(30.5?0.6)mm and(29.9?1.1)mm).The significance could be seen when comparing MSA-C and MSA-P with healthy control.The anteroposterior diameter of the fourth ventricle was significantly dilated in MSA patients than in healthy control((11.9? 2.8)mm and(9.0?2.1)mm).The MRI of MSA-C showed narrower MCP((13.3?1.9)mm and (15.8?1.2)mm and larger fourth ventricle((17.3?2.1)mm and(12.6?2.7)mm)than that of MSA-P.The MRI of MSA-P showed smaller globus pallidus and red neclei.Conclusions The volumetric MRI is a useful means in evaluating the brain structure atrophy in multiple system atrophy.The transverse diameter of the pans,though objectively reflecting the atrophy of the pons,can' t be used to differentiate MSA-P from MSA-C.The atrophy of MCP and the dilated fourth ventricle are common in MSA-C,while the atrophy of red neclei is common in MSA-P.
