Objective To investigate the dynamic change of serum high sensitive C-reactive protein (hsCRP) after carotid artery stenting (CAS) and its correlation with in-stent restenosis.Methods The serum hsCRP levels were determined before procedure,at 12 hours,7 days,3 and 6 months after procedure in patients who underwent CAS in the Department of Neurology,Jinling Hospital,Nanjing Their cerebral angiography was reexamined and whether there was in-stent restenosis after 6 months was observed.Results Eighty-four patients treated with CAS were included in the study.Fifteen (24％) had in-stent restenosis after CAS.The stenosis in 3 of them was ＞ 50％,and the stenosis m 12 of them was 30％ to 50％.The serum hs-CRP levels in all patients after procedure were significantly higher than those before treatment (all P ＜ 0.01 ),and they were significantly lower at 6 months after procedure than before treatment (all P ＜0.01).Univariate analysis showed that the proportion of diabetes in the restenosis group was significantly higher than that in the non-restenosis group (P＜0.01).At 7 days (8.83 ± 1.94 mg/L vs.6.77 ± 1.63 mg/L,t =14.398,P=0.044),3 months after procedure (8.26 ± 1.32 mg/L vs.4.58 ± 1.45 mg/L,t =17.569,P =0.008) and 6 months after procedure (7.04 ± i.07 mg/L vs.3.12 ± 1.28 mg/L,t =21.867,P =0.003),the serum hs-CRP levels in the restenosis group were significantly higher than those in the non-restenosis group,and the difference of the serum hs-CRP level (△ hs-CRP) before procedure and at 6 month after procedure was significantly lower than that in the nonrestenosis group (0.85 ± 0.13 mg/L vs.4.89 ± 0.94 mg/L,t =16.987,P =0.000).Multivariate logistic regression analysis showed that /hs-CRP (odds ratio [ OR] 2.392,95％ confidence interval [ CI] 1.538 -3.513; P =0.009) and diabetes (OR 1.840,95％ CI 1.372 -2.241; P =0.023) were the risk factors for instent restenosis.Conclusions The serum hs-CRP level increased significantly at 12 hours after CAS procedure,and then decreased continuously.At 6 months after procedure,the more decrease of the serum hs-CRP level,the lower risk of occurring in-stent restenosis was.

Complex odontoma is a relatively rare dental dysplasia. In particular, a complex odontoma with dentigerous cyst is seldom observed. A case of complex odontoma with dentigerous cyst is reported in this paper.

Objective To investigate the correlation of the lesion pattern of internal border zone infarction (IBZI) with atherosclerosis and outcome.Methods Eighty-one patients with IBZI were retrospectively divided into a simple IBZI group and a mixed IBZI group (combined with other infarct patterns) according to diffusion-weighted imaging (DWI).The clinical characteristics were compared between the 2 groups.And then,the mixed IBZI group was further divided into 3 subgroups:IBZI + pial infarct (PI),IBZI + perforating artery infarct (PAI),and IBZI + PI + PAI.They were compared with the simple IBZI group respectively.Results There were no significant differences in the dinical characteristics,such as age,hypertension,and the numbers of patients with stent implantation between the simple IBZI group and the mixed IBZI group.The proportions of severe stenosis and occlusion of internal carotid artery (ICA) and/or middle cerebral artery (MCA) (P =0.009) and MCA lesions (P =0.032) in the mixed IBZI group were significantly higher.Among the patients with MCA lesions,the severe stenosis in the simple IBZI group was significantly more than that in the mixed IBZI group (P =0.042),while the occlusive lesions in the mixed IBZI group were significantly more than those in the simple IBZI group (P =0.022).The short-term (within 7 days) exacerbation (P =0.039) and poor outcome at 90 days (modified Rankin Scale＞ 3) in the mixed IBZI group (P=0.030) were significantly higher than those in the simple IBZI group.The subgroup analysis showed that the proportions of the short-term exacerbation (P =0.001 ) and poor outcome in patients at 90 days (P =0.010) in the IBZI + PI +PAI subgroup were significantly higher than those in the simple IBZI group.Conclusions The IBZI patients combined with other infarct patterns often exist severe cerebrovascular stenosis and occlusion,and their clinical outcome was poorer.For patients with MCA lesions,the mixed IBZI occurred more in patients with MCA occlusion,and the simple IBZI occurred more in patients with severe MCA stenosis.

Objective To evaluate the prognostic value of hyperintense vessel (HV) in patients with acute middle cerebral artery (MCA) occlusion.Methods Seventy-four consecutive patients with first ever stroke(48 male and 26 female,the mean age was (60.7 ± 15.3) years) in the territory of MCA,retrieved from Nanjing Stroke Registry Program between May 2009 and February 2011,were enrolled assubjects.All subjects completed brain MRI,and MRA or DSA indicated proximal MCA occlusion.According to the location and extent of HV,all subjects were classified into 3 groups:without HV,proximal HV and distal HV.Clinical data were obtained and compared among patients with different grades of HV.Logistic regression analysis was employed to confirm the relevant factors of prognosis 90 days after index stroke.Results HV was observed in 49 (66.2％ ) of the 74 enrolled patients.Among patients with HV,7 (9.4％ ) were classified as proximal HV and 42 ( 56.8％ ) as distal HV.Initial NIHSS score ( 11 ( 1 -22) ),10-day NIHSS score ( 13.5(4-25) ),infarction size ( ＞2/3:5 cases(6.8％ ) ),and 90-day mRSscore (3-6 scores:12 cases( 16.2％ )) were significantly lower in patients with distal HV than those without (15(6-25),Z=-3.544;7(0-22),Z=-4.461;20 cases(27.0％),x2 =20.916;27 cases (36.5％),x2 =22.689;all P＜0.01).The NIHSS score decreased from baseline to that on 10 days and the mRS score decreased from 10 days to that on 90 days in patients with distal HV was more than that in patients without distal HV. Multivariate analysis revealed that patients with older age ( OR =1.111,95％ CI 1.036-1.191,P=0.003),high infarction size (OR=3.679,95％ CI 1.35-10.025,P=0.011) worsened outcome,whereas distal HV (P =0.012,OR =0.131,95％ CI 0.027-0.638)improved outcome.Conclusion Distal HV on FLAIR may predict a favorable outcome in patients with acute middle cerebral artery occlusion.
