Objective To discuss the effect and clinical value of serum sialic acid (SA) and lactadherin(MFG-E8) in the coronary atherosclerotic heart disease(CHD).Methods Selected 295 patients who visited to Wuhan University Renmin's Hospital cardiovascular medicine (from January to June, 2014), and then according to the results of coronary angiography divide the subjects into control group (n =78, the result of coronary angiography completely normal)and coronary heart disease group(n =217, the results of coronary angiography showed that one major coronary stenosis was more than 30％).Detected their serum level of lipid, SA, MFG-E8, hs-CRP index.At last, analyze the differences of SA and MFG-E8 between these groups, and the correlation with the severity of coronary stenosis (symbolize with Gensini score), use the binary logistic regression analysis to research the relationship among the serum level of SA, MFG-E8 and the risk of CHD.Results Compared with the control group, the patients with CHD have a higher level of serum SA and a lower level of MFG-E8 (U =4 402.5, 2 736.0 respectively,P ＜0.001);the AMI group has a higher level of serum SA than the StA and UA groups (U =1 329.0,957.5 respectively, P ＜0.001);the AMI group has a lower level of serum MFG-E8 than the StA groups (U =1517.0, P ＜ 0.001).The spearman correlation analysis showed that the serum SA has a positively correlation with the level of TG, hsCRP and Gensini score, and has a negatively correlated with the level of MFG-E8 (r =0.214, 0.462, 0.378,-0.322 respectively,P ＜0.01);the MFG-E8 has a negatively correlated with the level of TG, hsCRP and Gensini score (r =-0.18,-0.425,-0.564 respectively, P ＜0.01).Binary logistic regression analysis showed that there was a positive correlation between the serum SA and the risk of CHD (OD =4.782, 5.319, 4.179 3.832, 3.648 respectively, P ＜0.001), and the was a negative correlation between the serum MFG-E8 and the risk of CHD (OD =O.118, 0.112, 0.127, 0.135, 0.134 respectively, P ＜ 0.001).Conclusion With the serum SA rised and the MFG-E8 reduced, the risk of coronary heart disease was higher, combined detection these two indexes may be able to diagnose the CHD and assess the degree of stenosis and the risk of CHD.

Objective Many studies have proved that the ABCD 2 score can be used to predict early stroke risk after transient ischemic attack ( TIA) , but few reports are seen on its predictive value for early stroke risk after TIA in different types of circulation . This article aimed to evaluate the ABCD 2 score in predicting early stroke risk following anterior or posterior circulation TIA . Methods Patients with definitely diagnosed TIA consecutively included in Nanjing Stroke Registration System from September 2011 to December 2012 were classified into anterior and posterior circulation TIAs .Various risk factors were collected and a 90-day follow-up was conduc-ted.The ABCD2 score was obtained from each patient and its predictive value assessed using the receiver operating characteristic curve. Results A total of 204 patients were analyzed in the study , including 59 (28.9%) females, 143 with anterior and 61 with posterior circulation TIA, aged 63.7 ±11.2 years.There were no statistically significant differences in the incidence rate of stroke within 90 days between the anterior and posterior circulation TIAs (11.2% vs 9.8%, P=0.776).The mean ABCD2 score was re-markably higher in the anterior than in the posterior circulation TIA (3.7 ±1.5 vs 2.5 ±1.3, P<0.001).The area under the curve (AUC) in predicting stroke risk was 0.711 for the former (95%CI:0.575-0.847, P=0.006) and 0.555 for the latter (0.298-0.820, P=0.637). Conclusion The ABCD2 score can predict early stroke risk in anterior but not in posterior circulation TIA .

Objective: To study the role of simian virus 40 large T antigen(SV40LTag) and telomeras in the proliferation of endothelial cells in hemangioma. Methods: The expression of SV40LTag was examined in 100 cases of hemangioma with immunohistochemistry, telomerase activity and telomeric length were measured by RT-PCR based telomeric repeat amplification protocol(TRAP) assay, telomeric restriction fragment (TRF) analysis and chemiluminescence in situ hybridization in 50 cases of hemangioma and 10 of squamous cell carcinoma. A sample of embryonic kidney endothelia was used as the contrdol. Results: SV40LTag expression was observed in 45 out off the 100 cases of hemangioma. Telomerase expression was found in 27 out off the 50 cases of hemangioma and all the 10 of squamous cell carcinoma. The telomeric length in hemangioma varied from 6.8 to 13.2 kb, 10.5-13.5 kb in squamous cell carcinoma and 12.4 kb in embryonic kidney endothelia. Conclusion: Transformation of endothelia by simian virus 40 may contribute to the occurring of hemangioma, telomerase may play a role in the proliferation of the endothelial cells in hemangioma.

Objective To study the alterations in neurobehavior of rats with diffuse axonal injury(DAI) and to evaluate the potential role of basic fibroblast growth factor(bFGF). Methods A weight-drop device was employed to build the DAI model.An injection of bFGF subdurally and subcortically was given to the bFGF therapeutic group(n=60).Besides,normal control(n=20) and injured control group(n=60) were established.The elevated walkway test,prehensile traction test,sensorimotor integration test and the Morris' water maze test were adopted to examine the motor and memory abilities.After the implantation of skull electrodes,P3-like potential was explored in rats before and after injury. Results After DAI,the scales of the elevated walkway test,prehensile traction test,sensorimotor integration test and the Morris' water maze test were decreased,and the rats in the bFGF therapeutic group presented a better behaviour in the early stage.The latency of P3-like potential prolonged significantly in rats with DAI,with the P3-like potential in the injured control group longer than that in the bFGF therapeutic group(P

Objective To study the alterations in pathology and immunohistochemistry in rats with diffuse axonal injury(DAI) and the effects from basic fibroblast growth factor(bFGF). Methods A weight-drop device was employed to produce DAI in rats.In the treatment group(n=60),bFGF was injected subdurally and subcortically.Besides,normal control group(n=20) and injury-control group(n=60) were also established.The pathological changes were observed by light microscopy and electromicroscopy,and the expression of brain-derived neurotrophic factor(BDNF),growth associated protein-43(GAP-43) and glial fibrillary acidic protein(GFAP) were also examined by immunohistochemistry. Results Typical pathological changes were observed in the basal portion of pons,corpus callosum and white matter of cerebral hemisphere in the rats with DAI.And an upregulation of GFAP,GAP-43 and BDNF was also found.In the treatment group,better outcomes of pathological changes were observed.bFGF increased the expression of BDNF and GAP-43,while inhibited the immunoreactivity of GFAP. Conclusion Topical application of bFGF can improve brain tissue regeneration and speed function recovery in rats with DAI,though its long-term effect warrants further study.
