Clinical data and laboratory and imaging findings were compared with age-and sex-matched patients with colorectal cancer(CRC) without ischemic stroke that were admitted to the same hospital during the same period. Univariate and multivariate analyses were performed to analyze the independent risk factors for CRCIS. A receiver operator characteristic curve was configured to calculate the optimal cut-off value of the products of the independent risk factors for CRCIS. RESULTS A total of 114 CRCIS patients and 114 CRC patients were included. Multiple lesions in multiple vascular territories were common in CRCIS patients(71, 62.28%). The levels of plasma D-dimer, carcinoembryonic antigen(CEA), cancer antigen 125, and neutrophil count were significantly higher in CRCIS patients than in CRC patients. Multiple logistic regression analysis revealed that plasma D-dimer levels [odds ratio(OR) = 1.002, 95% confidence interval(CI): 1.001-1.003, P < 0.001], CEA levels(OR = 1.011, 95%CI: 1.006-1.015, P < 0.001), and neutrophil count levels(OR = 1.626, 95%CI: 1.268-2.087, P < 0.001) were independent risk factors for CRCIS. In addition, receiver operator characteristic curve revealed that the area under curve for the products of plasma D-dimer, CEA, and neutrophil count was 0.889 ± 0.022(95%CI: 0.847-0.932, P < 0.001), and the optimal cut-off value for the product was 252.06, which was called the CRCIS Index, with a sensitivity of 86.0% and specificity of 79.8%.CONCLUSION Hypercoagulability induced by elevated CEA and neutrophils may be an important cause of CRCIS. The CRCIS index, which serves as a biomarker of CRCIS, needs further study.展开更多

Vaccines targeting NGIs may provide multifactorial protection against brain insults by overcoming the inhibitory effects of these NGIs and boosting the body's immune repair mechanisms. OBJECTIVE: To evaluate the effect of poststroke DNA immunization against NGIs on the rehabilitation for sensorimotor function of rat models of local cerebral ischemia. DESIGN: Completely randomized grouping design, and controlled experiment. SETTING: Brain Injury Research Laboratory, Department of Neurosurgery, National Neuroscience Institute, Singapore. MATERIALS: Sixty adult male Sprague-Dawley rats ranging in age from 45 to 120 days and in weight from 180 to 250 grams were provided by Animal Center of Department of Anatomy, Faculty of Medicine, National University of Singapore. pcDNA3.1(+)-neurite growth inhibitors (pcDNA-NGIs) a gift was provided by Dr. Xiao from Department of Clinical Research, Singapore General Hospital, Singapore. METHODS: The experiment was carried out at Brain Injury Research Laboratory, Department of Neurosurgery, National Neuroscience Institute, Singapore from August 2003 to April 2005. (1)The involved rats were randomized into 3 groups: pcDNA-NGIs group (group A), pcDNA3.1 (+) group (group B) and model group (group C), with 20 rats in each group. Left focal cerebral ischemia (FCI) was permanently induced through middle cerebral artery occlusion (MCAO) with the assistance of an operating microscope. Successful MCAO was determined by a 20% decrease to baseline in the ipsilateral cerebral blood flow. 100 μg of pcDNA-NGIs eluted in phosphate-buffered saline (PBS) was intramuscularly injected into the tibial muscle once a week after MCAO for 6 weeks in group A. As control, pcDNA3.1 (+) was also administrated in the same way in group B and nothing was administrated in group C. (2) The modified neurological severity score (mNSS), a composite of motor, sensory, reflex and balance tests, was used to test the sensorimotor deficit. The mNSS was graded on a scale of 0 - 18, i.e. normal score was 0, maximal deficit score was 18, and 1 point was warded for the inability to perform the tasks or the lack of a tested reflex. (3) The newly generated axons of corticorubral projection were traced by stereotaxic guided injection of 100 g/L biotinylated dextran amine. Rats were sacrificed two weeks after tracing, and cryostat coronal sections of midbrains (30μm) were reacted to BDA according to the manufacturer's instruction by the free-floating method. Images were captured on a DM RXA2 LEICA Microscope with a Spot Digital Camera system (Germany), and the numbers of labeled axons on the denervated side in four standard coronal sections including the red nucleus were manually quantified. MAIN OUTCOME MEASURES: (1) The number of newly generated axons of corticorubral projection. (2)The improvement in sensorimotor deficit. RESULTS: All the involved 60 rats entered the stage of final analysis. (1) The number of newly generated axons of corticorubral projection of rats: Only ipsilateral axons of CRP were noted with little evidence of fibers crossing to the contralateral red nucleus in rats of groups B and C. More BDA-positive fibers crossing the midline and terminating in the contralateral red nucleus in appropriate target areas mirroring the non-differentiated red nucleus were found in rats of group A. Quantitative analysis showed that BDA-labeled axons in the denervated side of rats in group A were more than those in group B (P 〈 0.05). (2) Improvement in sensorimotor deficit of rats: At 2 weeks after immunization, significant improvement in sensorimotor deficit was found in rats of group A. There were significant differences of improvement in sensorimotor deficit of rats between group A and group B or group C at 12 and 14 weeks after immunization (P 〈 0.05). CONCLUSION: (1) Poststroke DNA immunization against NGIs leads to increased sensorimotor recovery following FCI and compensatory newly growth of axons from corticorubral projection.展开更多

文摘Objective:To investigate whether The small nuclear RNA activating complex polypeptide 3(SNAPC3)gene rs12093 polymorphism is associated with ischemic stroke(IS)and Traditional Chinese Medicine(TCM)syndromes of IS.Methods:This study enrolled 774 patients with ischemic stroke(IS)and 793 normal controls.Massarray technology was used for genotyping.And genetic association analysis was estimated by PLINK program.Results:①SNAPC3 gene rs12093 polymorphism was significantly associated with the risk of ischemic stroke wind syndrome of IS[OR=0.76,95%CI(0.58-0.99),P=0.047 in dominant model)].②After adjusting age and gender,SNAPC3 gene rs12093 polymorphism and the score of ischemic stroke wind syndrome(Padj=0.037 in additive model;Padj=0.009 in recessive model),the correlation is statistically significant.③After adjusting age and gender,platelet(PLT)(Padj=0.024 in addiction model;Padj=0.039 in dominant model)and thrombin time(TT)(Padj=0.042 in dominant model)were significantly associated with rs12093 polymorphism in patients with ischemic stroke wind syndrome.Conclusion:SNAPC3 gene rs12093 polymorphism may affect the occurrence of ischemic stroke wind syndrome.
文摘Objective:Taking the Dictionary of Prescriptions as a clue,we collected effective prescriptions for treating Stroke,and systematically summarized the medication and compatibility rules of the core Chinese medicines for treating Stroke.Methods:A database of prescriptions for stroke based on complex relationship analysis system of traditional Chinese medicine was established.From the point of view of complex network,the hierarchy of drug compatibility rules of compound prescriptions(such as courtiers and envoys)was analyzed,the statistical characteristics of complex networks were analyzed,and an attempt was made to explain the characteristics of complex networks of drugs for stroke.Results:A total of 974 prescriptions were collected,including 1040 Chinese herbs.The core Chinese herbal medicines with nodal degree(>500)for Stroke were divaricate saposhnikovia root,liquorice root,Chinese angelica,tall gastrodia tuber,incised notopterygium rhizome and root.The compatibility relationship of the core Chinese medicines in the treatment of stroke is divaricate saposhnikovia root-liquorice root,ephedra-divaricate saposhnikovia root,divaricate saposhnikovia root-sichuan lovage rhizome,divaricate saposhnikovia root-Chinese angelica in order of frequency.Conclusion:Through the analysis of the common network structure of effective prescriptions for Stroke,the core prescription compatibility structure reflecting the prescription thinking and clinical characteristics was found.

文摘Objective:To explore the appropriate modeling method of the early warning model of ischemic stroke recurrence in TCM.Methods:This was a prospective,multi-center and registered study conducted in 7 clinical subcenters from 8 provinces and 10 cities in China between 3rd November 2016 and 27th April,2019.1,741 patients with first-ever ischemic stroke were recruited.Univariate analysis was carried out using distance correlation coefficient,mutual information entropy,and statistical correlation test.Multivariate analysis adopted multi-factor Cox regression model and combined with expert opinions in the field of stroke to determine modeling variables.The generalized estimating equation of longitudinal data and the Cox proportional hazard regression model of cross-sectional data were used to construct and compare in the early warning model of ischemic stroke recalls.The area under the ROC curve(AUC value)was used to evaluate the early warning capability of the model.Results:The follow-up time was 1-3 years,and the median follow-up time was 1.42 years(95%CI:1.37-1.47).Recurrence events occurred in 175 cases,and the cumulative recurrence rate was 10.05%(95%CI:8.64%-11.47%).The AUC values of the TCM syndrome and TCM constitution model were 0.71809 and 0.72668 based on the generalized estimating equation and the AUC values.Conclusion:The generalized estimating equation may be more suitable for the construction of early warning models of stroke recurrence with TCM characteristics,which provides a certain reference for the evaluation of secondary prevention of ischemic stroke.
