Thus management of emergency night nursing by those with authorized leadership may lead to improved efficiency and quality.

Objective To investigate the relationship between molecular biological markers and recombinant human endostatin targeted therapy in non-small-cell lung cancer(NSCLC).Methods 68 cases patients with non-small-cell lung cancer to meet the requirements were randomly divided into group A (n=34)and group B (n=34).Group A received docetaxel and cisplatin(DP)and gefitinib;group B received recombinant human endostatin on the base of group A.The biological markers species,such as,EGFR,KRAS,VEGF,BRCA1,EML4-ALK,ERCC1,β-tubulin and CD3 were detected by immunohistochemical.The types of population for different programs were summarized according to the expression of biological markers and progression free survival (PFS)of the two groups. Results Group B median PFS was significantly longer than that in group A;no matter low or high expression of VEGF and BRCA1,group B median PFS was significantly longer than that in group A(P<0.05);high expression of ERCC1,KRAS,EML4-ALK andβ-tubulin,group B median PFS was significantly longer than that in group A(P<0.05);low expression of EGFR and CD3,group B median PFS was significantly longer than that in group A (P<0.05 ).Conclusion No matter low or high expression of VEGF and BRCA1 ,low expression of KRAS, ERCC1,EML4-ALK and β-tubulin and high expression of EGFR and CD3 in patients with non-small cell lung cancer may be more sensitive to the treatment of DP and gefitinib combined with recombinant human endostatin.

Objective To explore the neuroprotective mechanism of mild hypothermia by studying the effect of mild hypothermia on neuronal apoptosis after transient global cerebral ischemia in rats.Methods A model of transient global cerebral ischemia was made by bilateral common carotid artery occlusion and hypotension in rats. The neuronal demage in the CA 1 section of the hippocampus after cerebral ischemia was observed by nissel body stain mothed;apoptosis was detected by in situ end-labeling of fragmented DNA using the terminal deoxynucleotidyl transferase reaction (TUNEL) and the electrical microscope.Results The hippocampal CA 1 section neurons in normothermic ischemic group were significantly deficit as compared with the false operative group in mild hypothermic ischemic group (P

BACKGROUND: Transcranial Doppler(TCD) spectrum analysis techniques cannot measure the diameters of blood vessels and therefore and not be used to calculate the changes of brain blood flow. A formula was designed for regional cerebral blood flow loss index(rCBFLI) following arteriostenosis when arteriostenosis index formula was deduced; the former may provide a reference to assess cerebral function.OBJECTIVE: To introduce the formula of cerebral blood flow loss ratio obtained basing on TCD results.DESIGN: Retrospective controlled study based on patients with cerebral middle arteriostenosis diagnosed with TCD and healthy people.SETTING: At the departments of neurology in a university hospital and in a military medical university affiliated hospital of Chinese PLA.PARTICIPANTS: Between October 1994 and December 2000,43 patients who were confirmed of arteriostenosis with TCD at outpatient or neurological ward of the First Affiliated Hospital of Fujian Medical University were enrolled into this study,and their TCD results were compared with 908 normal controls between March 1992 and September 2000.METHODS: Stenosis index (STI) formula was deduced from TCD results of 31unilateral and 12 bilateral stenoses at middle cerebral artery(MCA) . STI = 1- [ normal average blood velocity (Vm0) ÷ average blood velocity at stenosisSince(PI1 ÷PI0) may be equal to [post-stenosis blood flow(Q1) ÷ normal blood flow(Q0)],regional cerebral blood flow loss index is concluded as:MAIN OUTCOME MEASURES: rCBFLI,relationship between STI and Vm,as well as between rCBFLI and STI.RESULTS: rCBFLI formula was used to calculate the rCBFLI of 31 patients following unilateral MCA stenosis. rCBFLI of these 31 patients was obtained by Pearson statistical analysis. STI was found to be related to the average blood velocity at stenosis with relative coefficient(Vm) of(r) =0.76( P ＜ 0. 001 )and r = 0. 83 ( P ＜ 0. 001 ) . rCBFLI was proved to be correlated with Vm and STI with r = 0. 76( P ＜ 0. 01 ) and r = 0. 81 in 55 side MCA stenoses,and the difference was of statistical significance( P ＜ 0. 001 ).CONCLUSION: rCBFLI can be used to assess the decrement of regional brain blood flow due to the stenosis of supplying artery; also,it can be used to observe the changes of brain hemodynamics if combined with STI.
