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.

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.

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 set up the infectious disease monitoring platform upon the hospital information system(HIS).In order to study the infectious disease′s early discovery,early reporting,early therapy and early control,to improve the hospital′s capability of prevention and cure of the infectious disease,generally improving the medical treatment quality.METHODS The computer technic was used to auto-collect,save,process the patient′s information.RESULTS To realize the information be shared;play a role in real time effective monitor;to provide the basic information of medical treatment,scientific research,education and management.CONCLUSIONS Realizing the scientific,standardized,systematized management of hospital infectious disease is becoming an important part in the whole HIS as the hospital medical treatment control system.

AIM: To investigate the protective effect of ulinastatin on rats with hemorrhagic shock. METHODS: A prospective, controlled animal study was designed. The model of hemorrhagic shock in rats was produced by Chaudry method. After 60 min, rats were resuscitated by transfusion of shed blood and normal saline, but a half of them were treated with ulinastatin. At different time points after reperfusion, the levels of tumor necrosis factor-alpha (TNF-?), interleukin-6 (IL-6), malondialdehyde (MDA) and superoxide dismutase (SOD) in serum were detected. RESULTS: The levels of TNF-?, IL-6 and MDA significantly increased and the activity of SOD decreased. In the ulinastatin-treated groups, the blood pressure and heart rate were obviously improved; the levels of TNF-?, IL-6 and MDA significantly decreased and the activity of SOD had little change after hemorrhagic shock and reperfusion. CONCLUSION: Ulinastatin has a protection effect on rats with hemorrhagic shock by suppressing the production of inflammatory factors and reducing oxidative damage.
