BACKGROUND: The observation of vascular endothelial growth factor gene expression of cerebrovascular diseases and ultrastructure of cells may be helpful to understand angiogenesis and its relative cellular factors involved in the pathogenesis at cellular and molecular levels. OBJECTIVE: To investigate the method of culture of human cerebral cap illary endothelial cell by separation of capillary fragment in vitro, and to ob serve vascular endothelial growth factor gene expression and ultrastructure of cells. DESIGN: A randomized controlled research on technique and method. SETTING: The neurosurgery department of a general hospital of a military area command of Chinese PLA and the neurosurgery department of a college hospital. PARTICIPANTS: Eighteen patients with arteriovenous malformation of brain(Spetzler Ⅱ-Ⅲ grade), as confirmed by aortocranial angiography before operation, in the Department of Neurosurgery, General Hospital of Shenyang Military Area Command of Chinese PLA were included. The material was obtained from fresh integrated specimen of arteriovenous malfor mation of brain with surrounding fresh brain tissues during the opera tion. Capillary endothelial cell was separated by homogenate, filtration and enzymatic digestion techniques. Cells grew well in culture flask and were divided into 4 groups(hypoxia state for 2, 4, 8 hours groups and control group). Each group contained four flasks.METHODS: Simulation of anoxia condition: volume faction 0.95 N2 and volume fraction 0.05 CO2. Expression of factor Ⅷ related antigen in cells was detected by immunohistochemistry. mRNA expression of vascular endothelial growth factor on endothelial in every group was observed by RT-PCR, protein content of vascular endothelial growth factor in supernatant detected by enzyme-linked immunoadsordent assay, and cellular ultrastructural change observed by transmission electron microscopy.MAIN OUTCOME MEASURES: mRNA expression of vascular endothelial growth factor on endothelial cell and protein content of vascular endothelial growth factor in supernatant in control group and every hypoxia groups; cellular ultrastructural changes.RESULTS: Under phase contrast microscope, cultured living cells had mono-layer pebble-like typical character. More than 90% of were factor Ⅷrelated antigen(FⅧ-RA) staining positive. mRNA and protein expression of vascular endothelial growth factor in hypoxia 4 hours group was 0.98 ±0. 19,( 180. 77 ± 20. 15) ng/L, which was significantly higher than in control group [0, (26. 20 ± 6.33) ng/L, P < 0.01 ]. Eight hours later, expression decreased [(0. 35 ±0.07), (31.68 ±8.34) ng/L]; swollen mitochondrion, dilated endoplasmic reticulum, and lysosome vesiculation were found.CONCLUSION: Humane cerebral capillary endothelial cell can be cultured by separation of capillary fragment, which is easy to operate and the cellular purity is reliable. In the early stage of ischemia and hypoxia, expression of vascular endothelial growth factor is not enough to maintain cellular ultrastructure integrity. Cells may be injured along with the prolong of hypoxia.Zhao MG, Tang T, Gao YZ, Pu PY, Wei XZ.

Objective To evaluate the incidence and to investigate risk factors of supraventricular arrhythmia (SVAs) in postoperative cancer patients in intensive care unit ( ICU ). Methods Data of 570 patients consecutively admitted to oncologic surgical ICU of Cancer Hospital of Chinese Academy of Medical Sciences from Nov. 2008 to Oct. 2009 were retrospectively collected. Univariate and multivariate logistic analysis were conducted for potential factors that influenced SAVs. Results Thirteen patients with a history of atrial fibrillation (AF) were excluded and 557 patients were eligible for the study. SVAs occurred in 72 patients ( 12. 93% ). Multivariate analysis showed four independent predictors of SVAs including age ( OR = 1. 066,95%CI: 1. 034 - 1. 099,P <0. 001 ) ,a history of coronary heart diseases ( OR = 2. 644,95% CI: 1. 459 - 4. 790,P < 0. 05), sepsis ( OR = 2. 374,95% CI: 1. 098 - 5. 135, P < 0. 05 ) and intra-thoracic procedure ( OR =2. 322,95 % CI: 1.061 - 5.084, P < 0. 05 ) . ICU length of stay, severity ( APACHE Ⅱ scores in SVAs patients) were significantly greater in patients who were not affected by SVAs ( ICU stay: [2 ( 1 ~ 77 )]vs [3 ( 1 ~ 40 )]days,P < 0. 001; APACHE Ⅱ score: [9 (0 ~ 37 )] vs [11 (3 ~ 38 )], P = 0. 001 ). Nine cases died in SVAs patients ( 12. 5% ) and 19 died in the non-SVAs patients (3.9%), with significant difference between the two groups( x2 = 9. 673, P = 0. 002). Conclusion In oncologic surgical ICU, the incidence of SVAs is high. Age,history of coronary heart diseases, sepsis and intra-thoracic procedure were independent rsik factors of SVAs. SVAs prolong ICU length of stay. SVAs is a marker of critical illness severity.
