Objective:To evaluate the clinical value of 64-slice spiral coronary CT angiography(CTA)in diagnosis of in-stent restenosis(ISR)after percutaneous coronary intervention(PCI)in patients with coronary artery disease.Methods:CTA was used to reconstruct and analyze the 345 segments(each stent was divided into three segments:proximal,middle and distal)of 115 stents in 60 patients with coronary heart disease after PCI.The results of selective coronary angiography(SCA)were taken as the golden standard to evaluate the sensitivity and specificity of CTA in diagnosis of ISR after PCI.Results:CTA clearly showed the location and length of the stents,the stenosis at stent and the characteristics of restenosis plaques.Thirty-nine in-stent restenosis lesions were found by CTA,including 8 calcified lesions and 31 non-calcified lesions.There were 25 lesions at the proximal end of the stent,7 at the middle and 7 at the distal end.Forty-two lesions were found by CTA,including 9 calcified lesions and 33 non-calcified lesions,with 26 at the proximal end,8 at the middle and 8 at the distal end.CTA correctly diagnosed 36 segments,missed 6,and misdiagnosed 3.The sensitivity,specificity,PPV,NPV and accuracy of CTA were 85.71%,99.01%,92.31%,98.04% and 97.39%,respectively.CTA had the highest sensitivity and specificity for diagnosis of the proximal ISR,being 96.15% and 100%,respectively.Proximal stent restenosis accounted for 64.10% of the total.Conclusion:CTA can clearly demonstrate the in-stent restenosis and has a high accuracy in diagnosing restenosis after PCI.CTA is a safe,simple and reliable noninvasive diagnostic method for diagnosis of in-stent restenosis after PCI.

N-Benzyl matrinol was obtained by hydrolysis, benzylation and reduction reaction from matrine. A series of hybrids (8a-8n) from (phenylsulfonyl)furoxan and N-benzyl matrinol were synthesized and biologically evaluated as anti-hepatocellular carcinoma agents. All target compounds were evaluated for anti-proliferative activity against human hepatocellular Bel-7402, SMMC-7721, Bel-7404, and HepG2 cells in vitro by MTT method. The results indicated that all of these compounds had potent anti-proliferative activity which were more potent than their parent compound and 5-FU, especially 8a-8h and 8j showed the strongest anti-HCC HepG2 cell activity with IC50 values of 0.12-0.93 μmol x L(-1).

Objective To evaluate the roles of magnetic resonance imaging and proton magnetic resonance spectroscopy(1H-MRS) in the diagnosis of meningiomas. Methods 98 patients with meningiomas underwent conventional pre-contrast MR and contrast MR. Among them, 28 cases had two dimensional single voxel or multi voxel 1 H-MRS simultaneously both in the lesion's region and the contralateral side. Results On precontrast MR images of 98 cases, T1 WI showed 58.1% (61/105) isointensities, 31.4% (33/105) faintly low intensities and 10. 5% (11/105) mixed intensities; T2WI showed 40. 0% (42/105) isointensities, 41.0%(43/105) hyperintensities, 10.5% (11/105) faintly low intensities and 8.5% (9/105) mixed intensities. After administration of Gd-DTPA, the solid part of the tumors exhibited various enhancement in all the 98 cases.28 cases of MRS exhibited specific different spectral peaks, including increased of choline-containing compounds(Cho), absent or decreased of acetylaspartate(NAA), and the unchanged of creatine(Cr). The value of NAA, Cr, Cho, NAA/Cr, Cho/Cr, NAA/Cho in the tumor center of meningioma were 0. 09 ± 0.06,0.31 ± 0. 22, 0.46 ± 0. 16, 0.33 ± 0. 42, 1.50 ± 0. 68, 0. 15 ± 0.08, compared with the contralateral normal region, Cr has no significant difference (P ＞ 0. 05), NAA, Cho, NAA/Cr, Cho/Cr, NAA/Cho had significantly differences(P ＜ 0.05). Conclusion Conventional pre-contrast MR and contrast MR is the most important dignostic means for meningiomas, 1H-MRS combined with MRI can improve the diagnostic accuracy of meningiomas.

Oral hydroxycamptothecin nanosuspension (HCPT-Nano) with high supersaturated dissolution level, high permeation and well physical stability, was manufactured by microprecipitation-high press homogenization method. Its pharmaceutical properties were investigated, such as size and distribution, zeta potential, particle shape, physical existence condition, supersaturated dissolution level and so on. Particle size was measured by laser diffraction, and the mean diameters before and after lyophilization were 138 +/- 11.72 nm and 175 +/- 12.74 nm, respectively, for HCPT-Nano. Zeta potentials of HCPT-Nano was over -20 mV. The nanoparticles, being observed by transmission electron microscopy (TEM), were claviform or column in shape. DSC and X-ray diffraction revealed that HCPT existed in the form of crystal for HCPT-Nano. And HCPT-Nano could maintain higher supersaturated dissolution level for long time. So it supplied the possibility of improving oral bioavailability of HCPT when combining together admoveatur of P-gp inhibitor, CsA.
