Glioma is a common tumor of the central nervous system. Tumor cells and tumor microvascular endothelial cells play a very important role in the development and progression of gliomas. Nogo protein is a kind of inhibitory protein in myelin sheaths of the central nervous system and an inhibitor of axonal regeneration in the central nervous system. This paper reviews the relationship between glioma cells and glioma microvascular endothelial cells.

Objective To explore the impact of burden,positive feelings,coping style and social support on caregivers' fatigue of dementia patients.Methods 190 caregivers of dementia patients were investigated by using the questionnaires of Caregivers Burden Inventory(CBI),Positive Aspects of Caregiving(PAC),Simplified Coping Style Questionnaire (SCSQ),Social Support Rating Scale (SSRS) and Fatigue Scale-14 (FS-14).Results The caregivers' fatigue of dementia patients was positively correlated with burden(r=0.56,P＜0.01),negative coping style(r=0.31,P ＜0.01),and negatively associated with positive feelings(r=-0.33,P ＜0.01),social support (r =-0.36,P ＜ 0.01) and positive coping style (r---0.55,P ＜ 0.01),respectively.Path analysis showed coping style and social support had direct impacts on fatigue; burden had a direct impact on fatigue,and also had an indirect influence on it through coping style or social support; fatigue might be decreased by positive feelings and increased by negative coping style.Conclusion To prevent and relieve the caregivers'fatigue of dementia patients,caregivers should be encouraged to take positive coping style and increase social support so as to reduce burden and increase positive feelings.

Objective To observe the features of cognitive function impairment in different locus of cerebral stroke and study the correlation between locus of cerebral stroke and cognitive function impairment.Methods Cognitive function was evaluated by Montreal cognitive assessment(MOCA) in 100 patients with stroke(63 cases of cerebral infarction,37 cases of cerebral hemorrhage).The locus of cerebral stroke in the 100 patients were including frontal lobe 15 cases,parietal lobe 15 cases,temporal lobe 12 cases,occipital lobe 8 cases,thalamus 14 cases,basal ganglia 20,cerebellum 8 cases and pons 8 cases.Correlation between the locus of cerebral stroke located by CT/MRI,and cognitive impairment was analyzed with 7 items(ORI,EF,NAM,MEM,ATT,LANG,ABS) of MOCA.Results(1) Stroke locus in frontal lobe,temporal lobe,parietal lobe,occipital lobe,thalamus and basal ganglia had correlation with obvious cognitive function impairment(all P

OBJECTIVE: To standardize the management on test of hospital preparations to ensure the quality of preparations. METHODS: The Access database and Word application of in Microsoft Office automatic groupware were integrated organically using VBA programming, and the data management system suitable for hospital preparation test was designed. RESULTS: The print files of various primary records and reports related to testing work exhibited beautiful page and uniformed format. Testing data of preparations were included into data base by computer recording, which facilitated data inquiry and data processing related to quality of hospital preparations. CONCLUSION: Due to this system, both the efficiency and quality of hospital preparation test work have been enhanced, which contributes to institutionalization and standardization of hospital preparation work.

OBJECTIVE: To determine Ginsenoside Rg1,Ginsenoside Re and Ginsenoside Rb1 in Yixin fumai granula by HPLC.METHODS: Samples were determined on a Diamond C18(150 mm?4.6 mm,5 ?m).The mobile phase consisted of accetonitrile-water by gradient elution with flow rate at 1 mL?min-1,UV detection wavelength at 203 nm,column temperature at 25 ℃ and sample size at 10 ?L.RESULTS: The linear ranges of Ginsenoside Rg1,Ginsenoside Re and Ginsenoside Rb1 were 0.645～6.450 ?g(r=0.999 8),0.54～5.40 ?g(r=0.999 7) and 0.605～6.050 ?g(r=0.999 9),respectively;the average recoveries were 100.59%(RSD=2.03%),98.70%(RSD=1.46%)and 98.99%(RSD=1.19%),respectively.CONCLUSION: The method is sensitive,simple and accurate,and it can be used for the quality control of Yixin fumai granula.

Objective To investigate the hemodynamics and structural effect of rat endothelial progenitor cells (EPC) transplant on pulmonary artery hypertension (PAH) induced by monocrotaline(MCT) in rats.Methods EPCs were identified and marked.Twenty-one days after injection of EPCs,the pulmonary hemodynamic parame- ters,average pulmonary artery pressure (mPAP),right heart index were determined.The vascular endothelial cells and pulmonary vascular structural changes were verified by fluoresccuse microscope.Results Compared with the model,EPCs treatment(n=10) decreased mPAP significantly (mPAP,EPCs:25.9?0.7 mmHg vs model group:29.3?2.2 mmHg,P

Objective To compare the efficacy and safety of topical anesthesia,conscious sedation and intravenous anesthesia during endoscopic varices ligation(EVL).Methods Patients underwent EVL were divided into 3 groups to receive different anesthetic methods,namely topical anesthesia,conscious sedation and intravenous anesthesia,with 50 subjects in each group.The changes of vital signs,the tolerance to stimulation of the procedure,the time of operation,the rate of complication were recorded and compared between 3 groups.Results The procedure of EVL were completed in all patients.In topical anesthesia group,40(80%)patients had nausea and vomiting,9 cases(1 8%)tried to pull out the endoscopy.The mucosa at the entrance of the esophagus were injured in 10 cases(20%).Massive bleeding occurred in 4 patients(8%)during operation because of nausea and vomiting.In conscious sedation group,only 7 patients(14%)had mild nausea and vomiting,and no complication of variceal bleeding occurred.The mucosa at the entrance of the esophagus was injured in 5 cases(10%).In intravenous anesthesia group,no patient had nausea or vomiting.The respiratory rate,heart rate and mean artery pressure decreased during the procedure,but without significant difference(P＞0.05).The operation time in intravenous anesthesia group WaS shorter than that in other two groups,but without significant difference(P＞0.05).Conclusion EVL can be completed under 3 different anesthetic methods,while EVL under conscious sedation is more effective and safe.
