objective to evaluate the role of mr perfusion weighted imaging in preoperation diagnosis of meningiomas.methods mr perfusion weighted images was performed in 47 patients with meningiomas followed by conventional imaging.results the mean rcbv values of angioblastic was the highest in the parenchyma of tumor.the mean rcbv values of malignant group was the lowest.the biggest mean rcbv values among different type meningiomas was statistically significant.the biggest mean rcbv values between benign and malignant group meningiomas was statistically significant,but not in the peri-tumor edema.conclusion the rcbv values were useful in the preoperative differentiation diagnosis of different types of meningiomas.those in the peri-tumor edema were useless in the preoperative differentiation diagnosis of different types of meningiomas.

目的 探讨磁共振灌注成像技术对脑膜瘤术前分型及良恶性鉴别的临床应用价值。方法对47例脑膜瘤病人行mr灌注成像检查，对5种亚型的良性脑膜瘤的mr灌注成像进行分析，并与非典型性及恶性脑膜瘤进行比较。结果血管瘤型脑膜瘤实质部分的rcbv值均数最高，恶性组脑膜瘤的rcbv值均数最低。各亚型间瘤体实质最大rcbv值均数间差异有统计学意义(p＜0.05)，良恶性脑膜瘤实质部分最大rcbv值均数间差异有统计学意义(p＜0.05)。瘤周水肿区的rcbv值均数间差异无统计学意义(p＞0.05)。结论 rcbv值对脑膜瘤术前分型及良恶性鉴别有所帮助，而瘤周水肿区的rcbv值对脑膜瘤分型及良恶性鉴别未显示临床实用价值。

Stenosis of internal caroid antery was found in 32 of 48 branches in 24 case. 5 branches were occlusive and 11 branches were normal. 22 cases with large or moderate cerebral infarction volume （＞5 cm3） confirmed by CT and MRI were smaller than those on MSCTPI as having abnormal perfusion lesions,which were moderate and obvious stenosis and occlusion on MSCTA.

METHODS: A dose-response relationship of 8-OH-DPAT, spontaneousphrenic nerve activity and a nociceptive C-fiber reflexwere established simultaneously in an in situ perfused, nonanesthetized,rat brainstem-spinal cord preparation. Fentanyl was administered in situ to investigate the interaction with 8-OH-DPAT on phrenicnerve activity and nociceptive CFR.

Then the experimental rats were treated with posthepatic manipulative bleeding or IH-VC manipulative bleeding at 10 min after reperfusion.

Two percent of body weight posthepatic manipulative bleeding with blood transfusion at 10 min after reperfusion significantly decreased circulating MDA, ALT and AST levels and improved survival rate.

Based on the laser longitudinal mode splitting theory, a novel scheme of dual-frequency laser with large frequency-difference is presented using electrically controlled birefringence of liquid crystal, and the transmitted resonant mode splitting by birefringent of Fabry-Perot etalon has been analyzed theoretically. A new element of liquid crystal Fabry-Perot etalon is designed and fabricated, which serves as aselector and splitter of both laser longitudinal modes and Fabry-Perot etalons transmitted resonant modes. Two different experimental systems of laser-diode end-pumped Nd:YAG laser have been set up using two different LDs, and the transmission of liquid-crystal cell have been measured. When the empty LCFP is inserted in the cavity of high-power LD pumped Nd:YAG laser, the oscillation of a single laser longitudinal mode have been observed, such a result shows that the designed and fabricated LCFP element is capable of selecting single axial mode. While an anti-reflected liquid crystal cell is inserted in the cavity of Nd:YAG laser end-pumped by the high-power LD, it is difficult to confirm weather the laser longitudinal modes have been spitted or not. The subject is summarized in this thesis and the improvement of the project has been presented.

BMSCs were isolated, depurated, cultivanted, and identified,then incubated with the concentration of 25μg Fe per milliliter at 37℃in 5% CO2. The labeled cells were stained by Prussian blue/trypan blue,and observed under fluorescent microscope.2. The labeled cells of different density (1×104/ml,5×104/ml,1×105/ml,5×105/ml,1×106 /ml,5×106/ml)were imaged by MRI with T1WI, T2WI and T2*WI sequences;and the same density (5×104/ml,1×105/ml)labeled cells were imaged by T2*WI sequences at different time.Then the signal intensities were measured and statistically analyzed.3. The model of rabbit renal ischemia-reperfusion injury was set up and treated. Then BMSCs(5×105)were injected into 16 recipient rabbits(1abeled cells in 10,unlabeled cells in 6)from ear vein.MR images of kidneys were obtained respectively at the time points of 0,1,3,5, 8 days after transplantation and before transplantation. MR imaging findings were analyzed,which were correlated with histological findings.
