BACKGROUND: Bone marrow mesenchymal stem cells (BMSCs) as a genetic carrier are beneficial to keep a genetic stability of exogenous gene. BMSCs can transfer human vascular endothelial growth factor (hVEGF) gene into the myocardial infarcted area. It is possible to obtain a cooperation of gene and cell therapy. OBJECTIVE: To investigate the angiogenesis at myocardial infarcted area of rats undergoing the transplantation of BMSCs transfected with hVEGF gene and in vivo expression of VEGF gene. DESIGN, TIME AND SETTING: A randomized control experiment was performed at the Institute of Paediatrics of Hunan Children's Hospital and Central Laboratory of Xiangya Second Hospital of Central South University from 2004 to 2007. MATERIALS: Male clean inbred strain Wistar rats were selected in the study. Rat models of myocardial infarction were established by ligation of coronary artery. METHODS: BMSCs were harvested from rats by density gradient centrifugation and adherent culture. Plasmid PeDNA3. 1-hVEGF 165 were transfected at 80%-90% cell confluence. Rat models of myocardial infarction, constructed by ligation of the left anterior descending coronary artery, were randomly divided into 4 groups. 2 weeks after the ligation,BMSCs transfected with hVEGF gene were injected into rat models in the combination group at the myocardial infarction zone. BMSCs were injected into cell group. Liposome-pcDNA3.1-VEGF165 DNA compound was injected into gene group. Culture medium was injected into control group. MAIN OUTCOME MEASURES: Capillary density and VEGF gene expression in the myocardial infarcted area of rats in each group four weeks after injection. RESULTS: Capillary density was the highest at rat myocardial infarcted area in the combination and gene groups, followed by the cell group (P=0.001, 0.029) and the control group (P=0.028).Reverse transcriptase-polymerase chain reaction (RT-PCR) showed that the hVEGF165 gene was expressed in the combination, gene, cell and control groups from higher level to lower level in order. CONCLUSION: BMSCs as the vector of VEGF gene are beneficial to its stable expression.Transplantation of BMSCs transfected with hVEGF gene is helpful for angiogenesis at myocardial infarcted area of rats. Its outcome is better than gene or cell therapy alone.

Objective: To determine the appropriate time of early administration of dopamine (DA) before nitroglycerin (GTN) for establishing rat model with vasomotor abnormalities. Methods: Rats were divided into 5 groups: normal group, DA Group and other 3 groups in accordance with DA at different time points (10, 30, 45 min) plus GTN .Common carotid artery (CCA) blood flow velocity was dynamically measured with pulsed Doppler flow probe to evaluate the influence of DA, GTN on blood flow velocity rate(BFVR). Results:The blood flow velocity rate induced by DA of All medication administration was different from the normal group within 10 minutes(P < 0.05). However, the differences were not statistically significant after 11 min(P > 0.05). The BFVR of 10min interval group had differences with the DA group at 45min, 50min, 55min, 60min, 65min and 70min(P < 0.05 or P < 0.01). CCA BFVR of 45 min interval group was statistically significant different from the DA group at 80, 85, 90, 95 min and 100 min(P < 0.05). No statistically significant differences existed between CCA BFVR of 30min interval group and DA group (P > 0.05). Conclusion: Subcutaneous injection of DA, 45m in after injection of GTN can induce vasomotor abnormalities in rat with phase characters. The model may be useful for vasoactive screening of anti-migraine drugs.

Objective To study the methods of delineating the whole length of bilateral facial nerve canals in one image. Methods High resolution computed tomography of the temporal bone was performed in 60 cases (120 ears) by Philips Mx8000 multislice spiral CT. Parameters: 120 kV, 200~250 mAs, Collimation: 0.5 mm, Pitch: 0.875, Scan time: 0.75 s/ring, Matrix: 512?512, Reformation interval: 0 1~0.2 mm, Reformation matrix: 1 024?1 024. Curved planar reformation(CPR)images were prepared along the facial nerve canal in the axial plane, and in the coronal and sagittal plane of multiplanar reconstruction(MPR). In the axial plane, a reference line was traced following the facial nerve canal from the internal auditory meatus, through the labyrinthine segment, the tympanic segment up to the second genu and mastoid segment. Another two protocols of curved reformatting were adopted: (a) a curved line was delineated along the facial nerve canal on the coronal reformatted image; (b) a curved line was drawn along the facial nerve canal on the sagittal reformatted image. The reference lines were carefully revised and moved exactly to the center of each segment of the facial nerve canal. For displaying bilateral facial nerve canals in one image, one reference line should be drawn along bilateral facial nerve canals. Results In 56 cases of 60 CPR, images in the axial plane, and coronal plane of MPR could show the unilateral or bilateral facial nerve canals clearly. The result of CPR of bilateral facial nerve canals in sagittal plane of MPR was unsatisfactory. The image on one side was often clear, but just part of it could be showed on the other. So the left and right facial nerve canals should be reformed separately. In 4 cases, CPR was unsatisfactory. In 1 of them the labyrinthine and tympanic segment had breaks because the patient′s head shook during the scanning. In 3 of them the facial nerve canals were showed unsatisfactorily because of the inexact position of head during the scanning. Conclusion The unilateral or bilateral facial nerve canals could be showed in one image by CPR. Combining the images of the high resolution CT in axial scan and MPR of the temporal bone, it would be helpful in the diagnosis of the lesions of facial nerve canal.
