Headache is a common clinical symptom.Some headache disorders belong to secondary category.Many intracranial disorders,such as head trauma,cerebral vascular diseases,intracranial tumors and inflammation,can lead to headache due to mass effect,inflammation reaction,stimulation of vasoactive substances and decreased intracranial pressure.Furthermore,many drugs and other substances,disorders of eyes,nose,ear,mouth,neck and other systemic disorders can also cause headache.Many headache disorders can be determined by detailed case history and physical examination.Blood test,lumber puncture,CT,MRI and other imaging examinations are necessary methods for finding the causes and the treatment of diseases.

The present hospital information systems are analyzed,with finding that hospital information isolated island phenomenon getting worse due to failure of interconnection of various systems and equipment vendors with different technologies.An integrated platform based on an enterprise service bus is proposed for hospital information,which can be connected into these heterogeneous systems,effectively minimizing the inter-system coupling,and achieving data and service interconnection,enabling an integrated and intelligent hospital architecture.

Objective To investigate the present status and developments of Chinese military neurosurgery, make an objective analysis about the achievements and deficiencies, and propose a developing trend for the field of Chinese military neurosurgery. Methods The scientific literatures of neurosurgery published domestically and abroad in recent 5 years were partially reviewed. The advances and achievements in basic researches and clinical works of neurosurgery acquired during the period of the 11th Five Year Plan were analyzed. Results During the period of the 11th Five Year Plan, Chinese military neurosurgery was still in the lead position in traditional areas such as traumatic brain injury. In the meantime, great achievements were obtained in the researches of brain and spinal cord tumors, endovascular treatment and functional neurosurgery, and 47 items of Army Science and Technology Advancement Prizes or Military Medical Achievement Awards were acquired. A great progress was made in personnel training. However, unbalanced development in neurosurgery field still existed within military departments, between military and civil departments and between different regions, so an enhanced technical interchange and cooperation is needed. Conclusions On the coming period, the research work of military neurosurgery should focuse on basic and clinical research of gene therapy to keep in step with neurosurgical trends in the world. On the other hand, attention should be paid to technological innovation with military features such as professional and general treatment of traumatic brain injury and researches on the development of protective equipments.

AIM:To explore the effects of transforming growth factor-α( TGF-α) in the monoclonal formation , proliferation, migration and adhesiveness of human endothelial progenitor cells ( EPCs).METHODS: The isolated and cultured EPCs were treated with various concentrations of TGF-α(final concentrations of 1, 5, 10μg/L, respectively).At the same time, the PBS control and epidermal growth factor receptor-tyrosine kinase inhibitor (EGFR-TKI) group (10μg/L TGF-αplus 1∶1 000 EGFR-TKI) were set.The effects of TGF-αon monoclonal formation , proliferation, migration and adhesiveness of EPCs were determined by clone formation experiment , thiazolyl blue tetrazolium bromide (MTT), EdU, Transwell and adhesion assays , respectively.The expression of epithelial growth receptor (EGFR) and vascular endothelial growth factor ( VEGF) were measured by Western blotting .RESULTS:Different concentrations of TGF-αall significantly induced the monoclonal formation , proliferation, migration and adhesiveness of EPCs (P<0.01), which were inhibited by EGFR-TKI.The results of Western blotting showed that TGF-αalso induced the expression of EGFR and VEGF with a cer-tain concentration effect ( P<0.01) .CONCLUSION:By combining with EGFR induced the expression of VEGF , TGF-αsignificantly promotes the related cell function of monoclonal formation , proliferation, migration, adhesiveness in EPCs.

OBJECTIVE To study the molecular mechanism of the drug-resistance of Gram-negative bacilli to the third generation of cephalosporins.METHODS MICs of 13 ?-lactams to the eleven Gram-negative bacilli clinical isolates were detected with the standard agar dilution technique.K-B disc confirmatory method was conducted to determine the ESBLs phenotype of the eleven isolates.The ESBLs encoding genes were analyzed by using PCR.RESULTS The eleven isolates were all resistant to the third generation of cephalosporins(MIC≥64 ?g/ml).Disk confirmatory test showed that 10 isolates produced ESBLs.The hydrolytic activity of the ESBLs from the 10 isolates to cefoperazone and cefamandole was very high.However,the hydrolytic activity of the ESBLs from the 10 isolates to ceftazidime was very low.CONCLUSIONS The enzyme activities and the genes of extended-spectrum ?-lactamases from 10 Gram-negative bacilli clinical isolates are preliminarily analyzed.These results provide the basis for further study on the molecular mechanism of the drug-resistence of Gram-negative bacilli.

Objective To study the characteristics of vestibular autorotation test (VAT) in patients with the posterior circulation transient ischemic attacks(PCTIA) ,further reveal the pathogenesis vestibular function damage because of PCTIA .Methods VAT was performed on 41 patients with posterior circulation transient ischemic at‐tacks(PCTIA group) and 30 healthy controls(control group) .Parameters analyzed included gains ,phases and a‐symmetry of VAT .The positive result of the test could be defined if any of the paramaeters was abnormal .Results In the PCTIA group and control group ,gains were enhanced without being reduced as showed in 25 (62 .5% ,25/40) cases and 5(16 .7% ) ,respectively (χ2 =7 .09 ,P<0 .01) ,gains were enhanced with reduced as showed in 10(25% ) cases and 0(0% ) ,respectively (χ2 =8 .78 ,P<0 .01) .Conclusion The results of VAT in patients with the PCTIA can show gains enhanced with reduced in different frequency .VAT can provide valuable reference on positioning as‐sessment of vestibular system damage in patients with PCTIA .

To construct human antibody repertory with phage display technology. Total RNA was extracted from peripheral blood lymphocytes (PBL) of clinical glioma patients and subjected to reverse transcription PCR. Variable region genes(V ? and V H genes) were amplified from the cDNA using nested polymerase chain reaction. V ? gene library was first constructed and attached to the Linker which could specially connect V ? gene and V H gene, then V H gene was cloned into V ? gene library to build ScFv repertoire. Positive colonies were selected randomly and sequenced. The results implied that amplified human V ? gene and V H gene could be derived from PBL of clinical glioma patients. ScFv phage antibody gene repertoire in about 2?10 6 capacity was successfully constructed. The sequencing indicated that the cloned genes encoded variable regions of heavy chains of human antibody and were highly homologous with human kappa heavy chain group III of Kabat's database. Then human antibody repertoire was successfully constructed with phage display technology. The present study can be used as a foundation for succeeding screening of specific antibody against human glioma.
