Objective To investigate the effectiveness of organ dose modulation (ODM) technology with respect to dose reduction and image quality of the sensitive organs during CTA of craniocervical arteries. Methods Ninety one patients suspected of arterial vascular disease and evaluated by CTA of craniocervical arterires were enrolled in this study. Patients were divided into group A (n=46) and group B (n=45) according to the order of examination. All patients hadCTA examination of craniocervical arteries. The ODM technique was used only in plain phase in group A and was used both in the plain phase and enhanced phase in group B. The tube current in the four direction (anterior,posterior,left,right) of thyroid and orbital area and radiation dose were recorded. The image quality of group A and group B was evaluated by objective indicators [CT attenuation values and contrast-to-noise ratio (CNR) of vessels in the thyroid area and orbital region ]and the subjective score. The independent samples t test was used for the statistical analysis of the objective indicators and nonparametric rank sum Mann-Whitney U test were used for subjective score. Results For A group, There were significant differences for the tube current at all directions of the thyroid gland and orbital area between the plain phase and the enhanced phase except the current at the posterior of the thyroid gland area(P value all<0.05),and the current in plain phase lower than that in enhanced phase. The mean current of thyroid gland and the orbital area were (604±43) mA and (656± 22) mA in the plain phase and (341±54) mA and (409±63) mA in enhanced phase. The differences were significant (t values were -10.909 and -38.454,P<0.01).CTDIvol and ED were (15.6±1.4) mGy and (1.44± 0.17) mSv in the plain phase and (17.4 ± 1.4) mGy and (1.60 ± 0.18) mSv in the enhanced phase, the differences were significant (t values were - 42.008 and - 32.130, P<0.01) . There was no significant differences for the objective indicators and the subjective score between group A and group B(P>0.05). Conclusion ODM technique can provide protective effect on the sensitive organs during craniocervical CTA examination without compromising the image quality.

Objective:To investigate the expressions of matrix metalloproteinase 9 (MMP-9), matrix metalloproteinase 2 (MMP-2), migration-inducing protein 7 (MIG-7) and filamin A (FLNa) in colon cancer tissues and their effects on prognosis.Methods:The tumor specimens and corresponding adjacent normal tissues of 899 colon cancer patients undergoing surgical resection in the Affiliated Huai'an No. 1 People's Hospital of Nanjing Medical University from January 2013 to December 2015 were collected. The expression levels of MMP-9, MMP-2, MIG-7 and FLNa in colon cancer tissues and adjacent normal tissues were measured by using enzyme-linked immunosorbent assay (ELISA), and the relationship between their expression levels and clinicopathological characteristics as well as prognosis of colon cancer was analyzed.Results:The expression levels of MMP-2, MMP-9 and MIG-7 in colon cancer tissues were (481±69) ng/ml, (262±85) ng/ml,(156±23) ng/ml, respectively, which were higher than those in adjacent normal tissues [(136±33) ng/ml, (191±21) ng/ml, (98±18) ng/ml], and the differences were statistically significant ( t was 41.591, 120.224, 59.896, all P < 0.01); the expression level of FLNa in colon cancer tissues was (19.5±3.2) ng/ml, which was lower than that in adjacent normal tissues [(65.4±8.3) ng/ml], and the difference was statistically significant ( t = 154.902, P < 0.05). The expression levels of MMP-9, MMP-2, MIG-7 and FLNa in colon cancer tissues were correlated with tumor diameter, Dukes stage, lymph node metastasis and degree of differentiation (all P < 0.05). Cox multivariate analysis showed that the high expressions of MMP-9, MMP-2, and MIG-7 and the low expression of FLNa were independent factors affecting the prognosis of patients (all P < 0.05). Kaplan-Meier analysis showed that the median overall survival time of patients with low expression of MMP-9, MMP-2 and MIG-7 was 55 months (95% CI 25-78 months), 56 months (95% CI 26-79 months) and 54 months (95% CI 25-78 months), respectively, which were longer than those with high expression, while the median overall survival time of patients with high expression of FLNa was 58 months (95% CI 27-80 months), which was longer than those with low expression, and the difference was statistically significant ( P < 0.05). Conclusions:MMP-9, MMP-2, MIG-7 and FLNa are closely related to the occurrence and progression of colon cancer. The high expression levels of MMP-9, MMP-2 and MIG-7 and the low expression level of FLNa have influences on the prognosis of colon cancer patients, and it can be used as important indicators for clinical prognosis judgement.

Objective To preliminarily discuss the effect of thrombectomy with the TREVO device in patients with acute ischemic stroke.Methods Six patients with acute ischemic stroke treated with TREVO device at the Department of Neurointervention,Beijing Fengtai You′anmen Hospital from April to June 2016 were analyzed retrospectively,including 2 patients with middle cerebral artery (MCA)occlusion (time window from 2. 7 to 5. 5 h),4 with basilar artery occlusion (time window from 4. 0 to 7. 0 h). The effect of thrombectomy was evaluated by the modified thrombolysis in cerebral infarction (mTICI ) scores. The National Institutes of Health Stroke Scale (NIHSS)scores were used to evaluate the neurological status of patients before and after treatment. The prognosis was evaluated by the modified Rankin scale. Results (1 )After 1 to 2 embolectomies,the occlusive arteries of 5 patients achieved recanalization (mTICI gradeⅡb-Ⅲ;posterior circulation in 4 cases,MCA in 1 case). (2)Compared with at admission,the NIHSS score in 1 of 2 patients with MCA occlusion was reduced by 8 points at discharge,and 1 was not any improvement;compared with at admission,the NIHSS scores in 3 of 4 patients with basilar artery occlusion were decreased by 8-26 points at discharge,and 1 was not any improvement;in 2 patients with MCA occlusion,the modified Rankin scale scores were 0 to 1 at 3 months after discharge (0 in 1 case,4 in 1 case);the Rankin scale scores in 4 patients with basilar artery occlusion at 3 months after discharge were 0 in 1 case,1 in 2 cases,and 5 in 1 case.Conclusion The preliminary experience of using TREVO device embolectomy for patients with acute ischemic stroke shows that it is more safe and effective.
