Objective To know the effects of training for community residents about cardiopulmonary resuscitation.Methods 60 community residents were trained by CPR with varied training methods,evaluated the effects by the ABC for life questionnaire.Results The knowledge of cardiopulmonary resuscitation among the trained community residents were better than before expect 4 aspects.Conclusions The knowledge of cardiopulmonary resuscitation in community residents was not enough,systemic training can effective promote their skills of CPR.

Objective:To compare the therapy effects of chemotherapy and non-chemotherapy groups and to determine the value of chemotherapy for adult diffuse low-grade gliomas. Methods:We reviewed and analyzed 64 patients with adult diffuse low-grade glio-mas admitted to the Beijing Tiantan Hospital from May 2005 to April 2008. Among the patients, 18 received 4 to 12 cycles of temozolo-mide chemotherapy after operation and radiotherapy, whereas the other 46 cases only received radiotherapy. The progression-free survival of the two groups was compared. Results:The median progression-free survival of the chemotherapy and the control groups were 67.8 and 51.3 months, respectively. The results of the comparison implied a significant difference (χ2=8.741, P=0.003). Conclu-sion:Chemotherapy can improve the progression-free survival of the patients with adult diffuse low-grade gliomas, and thus, can be recommended as its effective therapy.

Objective To observe the development of hematopoietic stem cell and the apoptosis of ICM(intermediate cell mass) in folic acid deficient zebrafish embryos and investigate the mechanism by which folic acid deficiency induces abnormal hematopoiesis.Method The folic acid deficient zebrafish model was induced by both using the dihydrofolate reductase antagonism methotrexate(MTX) and knock-down dihydrofolate reductase gene.The development of embryos was observed under microscope.The blood cells were detected by O-dianisidine staining.Whole-mount in situ hybridization and real-time PCR were performed to examine the expression of FLK-1,GATA1and GATA2.Apoptosis in intermediate cell mass(ICM) was examined by TUNEL(terminal-deoxynucleotidyl transferase mediated nick end labeling) method.Results The abnormal developments of ICMs were observed both in MTX treated embryos and DHFR knock-down embryos.O-dianisidine staining revealed that folic acid deficiency resulted in the decreasing number of blood cells.In folic acid deficient embryos,the expression of FLK-1、GATA1and GATA2 was reduced and the apoptosis in ICMs was increased.Conclusion The abnormal hematopoiesis in zebrafish induced by folic acid deficiency is related with the increasing apoptosis in ICMs and decreasing expressions of FLK-1,GATA1and GATA2.

ObjectiveTo investigate the language cortex organization characteristics of native Chinese. Methods20 patients who underwent language mapping via intraoperative direct cortical electrical stimulation (ioDCES) under awake anaesthesia for glioma in dominant hemisphere were analyzed retrospectively. Results16 patients were identified at least one language site, 3 patients located in the frontal and 1 patient in the temporal lobe. The language sites mostly located in the perisylvian region. The frontal language sites conformed to traditional Broca's areas, but the superior temporal gyrus contained much more language sites than the middle temporal gyrus.ConclusionHigh individual variability in language organization indicates a need for revision of the classical model of language localization. Because of the samples were too small, our current dates can't fully reflect language cortex organization characteristics of native Chinese.

OBJECTIVETo provide a reference for the development and utilization of Dai medicine by investigate the present situation and existing problems of traditional Dai medicine.

METHODCombined with the previous relevant investigations and literature in the field, the key and the development direction of traditional Dai medicine were analyzed.

RESULTThe textual research, history, species, distribution, endangered resources, protection status etc. were elaborated and the key strategy of further investigation was expounded.

CONCLUSIONDai medicine resources should strengthen the basic research, such as the protection of traditional knowledge, the textual research, quality standard, chemical composition, biological activity, exploration of medicinal resources, especially monographic study on protection of major endangered medicinal resources should be intensified, which will be rise the level of development and utilization of Dai medicine resources.

Objective To develop user-friendly information education-communication (IEC)materials and guidelines of malaria control for various target groups. Methods The participatory methods were used to make sure participation of target groups at each stages of IEC material development. Results A package consisted of interactive video, 2 posters for primary groups, sto ry booklet for students, manual for activities of "buddy system" for teachers, flipcharts for health staff at grass-root levels, guidelines on communication skill and how to use the first 5kinds of materials, was developed. Conclusion A set of user-friendly IEC materials and guidelines of malaria control has successfully been developed with sufficient participation of target groups.

Objective: To explore the diagnostic value of brachial-ankle artery pulse wave velocity (baPWv) in patients of heart failure with preserved ejection fraction (HFpEF). Methods: A total of 86 consecutive dyspnoea patients without coronary artery diseases (CAD) were studied and they were divided into 2 groups: HFpEF group,n=46 and Control group, the patients had no organic heart disease,n=40. The incremental diagnostic value of HFpEF by baPWv improving the echocardiographic index and plasma BNP level was assessed by logistic regression model, receiver operation curve (ROC) of multi-parameter combination and net reclassiifcation index analysis. Results: Multiple stepwise logistic regression analysis presented that the ratio of early mitral inlfow velocity to tissue Doppler velocity at the lateral mitral annulus, BNP level and baPWv had the independent predictive value for HFpEF diagnosis, P<0.05. The ROC for baPWv with the combination of 2 or 3 parameters was better than the ROC for a single parameter, P<0.05. The baPWv added with 2007 ESC consensus statement signiifcantly improved HFpEF diagnosis, NRI = 0.127,P<0.05. Conclusion: The baPWv combining with current diagnostic criteria could increase the diagnostic value in patients of HFpEF.
