In recent years,many researches shows event-related potential P300 has significance for evaluating of cognize in children. This paper summarizes the research of event-related potential P300 in the children with ADHD and TS to compare the differences and discuss the possible mechanism.

Objective To evaluate the relationship between cytotoxin-associated gene-A (CagA)seropositive of Helicobacter pylori (H .pylori )infection and risk of atherosclerotic cerebral infarction(ACI).Methods Related literatures were researched through literature retrieval ,literatures were obtained by uniformed criteria of inclusion and exclusion,and Meta analysis was performed with RevMan 4.2 software.Results A total of 10 literatures which met the inclusion criteria were retrieved,all were case-control study,case group included 907 studied subjects,and control group included 966 subjects;the included population were divided into Chinese subgroup and European Caucasian sub-group.Meta analysis of CagA seropositive of H .pylori infection and risk of ACI revealed that OR of the overall popula-tion,Chinese subgroup,and European Caucasian subgroup was 2.66(2.17-3.26),2.60(1.93-3.49),and 2.71(2.05-3.59)respectively;Meta analysis of CagA seronegative of H .pylori infection and risk of ACI revealed that OR of the overall population,Chinese subgroup,and European Caucasian subgroup was 0.74(0.49-1.10),0.81(0.45-1.48),and 0.64(0.37-1.09)respectively.The funnel plot and fail-safe number showed that there was no significant publication bias, the result was stable and reliable.Conclusion Chronic infection caused by CagA seropositive strains of H .pylori may be one of the risk factors of CAI,whether the eradication treatment of seropositive strains of H .pylori influences the process of atherosclerotic diseases like CAI needs to be further studied.

Objective To describe the clinical and radiological characteristics, the etiology, clinical course and MRI findings and prognosis of reversible splenial lesion syndrome ( RESLES) are analyzed.Methods Clinical and MRI findings of adult patients who presented with RESLES were retrospectively reviewed.Corresponding to severity of disability using Modified Oxford Handicap Scale ( MOHS ) , patients were classified into favorable outcome group (MOHS≤2)and poor outcome group(MOHS≥3),clinical and neuroimaging features between two outcome groups were compared.Results Eight patients fulfilled the criteria were included, who suffered from a broad spectrum of disorders, including mild encephalitis/encephalopathy, Marchiafava-Bignami disease and antiepileptic drug withdrawal.MRI found a high signal lesion in the splenium with or without the other parts of corpus callosum and extracallosal involved.The hyperintensity disappeared or lapsed comfirmed by repeated MRI.There is an significant difference on symptoms of severe disturbance of consciousness during clinical course and MRI showed extracallosal lesions between two groups (P<0.05).Conclusions RESLES is a rare entity with wide clinicoradiological spectrum due to varied diseases and conditions.Although overall symptoms of patients with RESLES trend to relieve, the prognosis of patients with severe disturbance of consciousness and extracallosal lesions are unlikely to be favorable.

Objective To explore the effect of TBL based on evidence-based medicine PICOS model in practice teaching of neurology. Methods Totally 47 medical undergraduates in our department were chosen and randomly divided into 2 groups during March 2016 to April 2016. 24 students in the trial group were taught with TBL based on PICOS, while other 23 students in the control group were only taught with conventional TBL method. After three times clinical practices, the test referring to disease pathogenesis, clinical manifestations, auxiliary examinations, diagnosis and treatments of related diseases was performed, and meanwhile, questionnaires were distributed to students in order to survey their satisfaction degree of teaching methods. All the evaluation results and scores of two groups were compared. Statistical data were analyzed by using t-test or Chi-square test with SPSS 17.0 software. Results The score of the theoretical test of trial group was significantly superior to the control group [(89.08±3.60) vs. (79.09±7.75), t=5.707, P=0.03 ]. Survey showed that in the experimental group , the number of students in the trial group who thought teaching method could help understand clinical thinking of neurology and could help integrate the theory into clinical practicewas significantly higher than that in the control group (P<0.05). Conclusion In the clinical teaching of neurology, the TBL based on PICOS model is more effective than conventional TBL method for medical undergraduates.

In the process of positron emission tomography (PET) data acquiring, respiratory motion reduces the quality of PET imaging. In this paper, we present a correction method using three level grids B-spline elastic method to correct denoised and reorganized sinograms for respiratory motion correction. Using GATE simulates NCAT respiratory motion model to generate raw data which are used in experiment, the experiment results showed a significantly improved respiratory image with higher quality of PET, and the motion blur and structural information were fixed. The results proved the method of this paper would be effective for the elastic registration.

BACKGROUND: With the rapid development of surgical techniques, unicompartmental knee arthroplasty has become an issue of concern in the treatment of osteoarthritis, which has achieved significant progress inreducing trauma and rapid rehabilitation.OBJECTIVE: To summarize the development history, curative effect of unicompartmental knee arthroplasty, and the research progress of lateral unicompartmental knee arthroplasty aided with computer navigation or robot system, thus providing reference for further study on unicompartmental knee arthroplasty.METHODS: Web of Science, and PubMed databases were searched for the literatures published from January 1955 to April 2017 with the keywords of unicompartmental knee arthroplasty, osteoarthritis, unilateral compartment, lateral knee arthroplasty.RESULTS AND CONCLUSION: A total of 562 articles were retrieved, and finally 75 English literatures were enrolled according to the inclusion and exclusion criteria. With the continuous improvement of unicompartmental knee arthroplasty, it can retain the cruciate ligament and more bone mass. Notably, strict indications and reasonable postoperative functional exercise are essential for obtaining optimal effectiveness. At the same time, the development of computer navigation and robot-assisted technology has opened up a new horizon for the treatment of osteoarthritis,which makes the operation more accurate and minimally invasive. But the application still needs to be studied in depth.

The bacterium Streptomyces peucetius produces doxorubicin and daunorubicin,and the two widely used anticancer antibiotics.Two open reading frames,drrA and drrB,were proposed to encode for an ABC (ATP-binding cassette) type of permease that carries out export of the antibiotic ABC (ATP binding cassette)-type transporter for the exportation of these two antibiotics.In this paper,the structure,expression and interaction of DrrA and DrrB protein and the research progress of the assembly and multi drug efflux function of DrrAB are briefly reviewed.
