Objective To study the value of carotid plaque magnetic resonance imaging (MRI) in pre-operation assessment in the elderly patients with carotid atherosclerosis and explore the possibility of minimizing the contrast weightings to gain sweeptime. Methods Totally 70 elderly patients with cerebral ischemia (average age of 68.8 years) underwent carotid MRI and digital subtraction angiography (DSA) due to the appearance of carotid plaque detected by ultrasound. Carotid plaque MRI was acquired with 3.0T MR scanner and 8 channel surface coil. The standard carotid plague MRI program included pre-and post-contrast T1 weighted imaging (T1WI), T2 weighted imaging, proton density weighted imaging and 3D time of flight MR angiography (3D TOF MRA). All these program were divided into two combinations: the 5-sequence MRI (all the sequences) and 2-sequence MRI (T1WI and TOF MRA). Digital subtraction angiography (DSA) in coronal and lateral views of carotid artery was performed with GE Advantx LCN+. The software SPSS 13.0 was used to statistically analyze the difference between MRI and DSA, and that of two sequence combinations was used in the detection of luminal stenosis and fibrous cap (FC) rupture. Results Totally 135 arteries were analyzed while 3 arteries in one patient were excluded due to the poor quality image and stent placement. The degree of luminal stenosis were (38.3±31.0)% and (38.5±30.9)%, respectively, detected by the two MRI sequence-combination with no significant difference (t=2.447, P>0.05) and was (35.1±31.8)% by DSA. There was a good concordance between MRI and DSA in luminal stenosis detection (Kappa value: 0.773). No statistical difference was found between two MR sequence combinations in detecting FC rupture (both in 36 vessels). DSA detected FC rupture of 16 vessels, showing remarkably difference contrast to MRI(χ2=12.0, P<0.01). Conclusions MRI can accurately detect the luminal stenosis and FC rupture. The short time scanning resulting from sequence optimization could make MRI much more suitable than DSA to do the pre-operation assessment for senile carotid atherosclerotic patients.

Objective To investigate the potential role of Lycium bararum polysaccharide (LBP) with or without interferon -inducible protein 10 ( CXCL10) in inducing dendritic cells ( DC) functional maturation by monitoring the alteration of cytokines for inducing DC maturation in peripheral blood and by detecting the expression of S-100 protein in tumor tissue, thus to reveal its mechanism of inhibiting experimental liver cancer. Methods H22 bearing mice model was established. The mice were randomized into model group, LBP group (50 mg/kg, ig), CXCL10 (right axillary subcutaneous injection of 15 μg/kg), LBP + CXCL10 group (LBP 50 mg/kg, ig, and right axillary subcutaneous injection of CXCL10 15 μg/kg), 5- fluorouracil (5FU) group ( intraperitoneal injection of 12mg/kg) , 12 mice in each group. The mice were administered the corresponding medicine once a day. After treatment for 2 continuous weeks, blood was sampled from infraorbital vein, and the tumor mass, spleen, thymus were extracted for the calculation of anti-tumor rate, thymus index and spleen index separately . The mRNA expression levels of interleukin 12 (IL-12) and tumor necrosis factor-α (TNF-α) in peripheral blood were detected by fluorescence quantitative PCR, the expression of S-100 protein in tumor tissues was detected by immunohistochemical assay. Results Compared with the model group, tumor growth in LBP group and LBP+CXCL10 group was obviously inhibited, and tumor-inhibitory rate was 55.90%, 50.91%, respectively. Meanwhile, the mRNA expression level of IL-12 was 2.94 folds higher in LBP group and 3.39 folds higher in LBP + CXCL10 group, and TNF-α mRNA expression level was 1.55 folds higher in LBP group and 4.74 folds higher in LBP+CXCL10 group than the model group, the differences being statistical significant ( P<0.05 or P<0.01). Results of immunohistochemical assay showed that S-100+DC number in LBP group and LBP+CXCL10 group was larger than that in the model group (P<0.05 ). Conclusion LBP and LBP+CXCL10 exert significant effect on inhibiting experimental liver cancer. The mechanism may be related with inducing the secretion of IL-12 and TNF-α, which plays a key role in inducing DC maturation, and with the increase of the number of DC in tumor microenvironment.
