OBJECTIVE: Cerebral endovascular stent implantation has become an important method to treat ischemic cerebrovascular disease. However, its application has been limited by restenosis following implantation. The effect and significance of ultrasound in identifying and reducing restenosis following endovascular stent implantation was explored. METHODS: A computer-based online search of VIP database and CNKI database was performed for articles recording ultrasound evaluation of ischemic cerebrovascular disease following endovascular stent implantation. A total of 22 articles were collected, and 6 were included. Inclusion criteria: application of intravascular ultrasound in carotid artery stent implantation; guidance and effect evaluation of intravascular ultrasound; short- and long-term effect evaluation of carotid artery stent implantation by color Doppler ultrasound and transcranial Doppler ultrasound. Exclusion criteria: outdate and repetitive studies. RESULTS: Intravascular ultrasound can precisely measure vascular lumina stenosis degree, stenosis length and luminal area before stent implantation to select stent with appropriate size and length and effectively guide stent implantation. Intravascular ultrasound probe can observe stent expansion, expansion symmetry, and precisely determine expanded stent size and attachment of stent to the vessel wall. Color Doppler ultrasound and transcranial Doppler ultrasound can monitor the short- and long-term effect of stent implantation so as to discover, treat and reduce restenosis as early as possible, confirm causes for restenosis following stent implantation, guide treatment of restenosis, reduce incidence of restenosis and improve stent implantation effect. CONCLUSION: Intravascular ultrasound remedies disadvantages of digital subtraction angiography, increases stent extension area and reduces incidence of restenosis. Following stent implantation, intravascular ultrasound can accurately detect stent expansion degree and attachment of stent to the vessel wall; Color Doppler ultrasound and transcranial Doppler ultrasound can monitor blood follow in stent, and play an important role in evaluating restenosis and preventing restenosis following endovascular stent implantation.

Objective To study the relationship between hyperferritinemia and early metabolism disturbance of sugar and Lipid.Methods 382 people in health examination from Hangzhou First People's Hospital were divided into hyperferritin group(A group)and hypoferritin group(B group)according to the level of ferritin.Blood fat,fasting blood glucose(FBG),uric acid(UA),hematoglobin(Hb),red blood cell count(RBC),hematocrit(HCT),mean corpuscular-hemoglobin concentration(MCHC)were determined,and adiposis hepatica was judged by ultrasonic inspection,then we analyzed by meams of statistics.Results The result showed that TG,LDL,HDL,ApoA1,ApoB,FBG,UA,Hb,RBC,HCT,MCHC had significant deviation between two groups.Ferritin was positive correlated with TG,TC,LDL,ApoB,Hb,RBC,HCT,and negative correlated with HDL,ApoA1.The incidence of adiposis hepatica in A group was obviously higher than B group.Conclusions Probably,ferritin was one of the markers of early metabolism disturbance of sugar and Lipid.

A semantic predication network was developed by processing the documents on schizophrenia into se-mantic predication sets using SemRep, from which the core information was extracted to produce a graphic summary which was consisted of highly cohesive cliques.The automatic methods for summarizing biomedical documents were studied using the network properties combined with semantic information.The subthemes in the summary obtained by clustering were evaluated according to the clique co-node matrix and the contents of the summary were assessed according to the reference criteria.The accuracy was 0.93, the recall was 0.68, and the F-value was 0.79 for the summary, indicating that this method can effectively recognize the core information in documents and the semantic information in network graphics.

Objective To investigate the therapeutic effect of Ganglioside(GM1) on acute cerebral infarction.Methods 60 cases with acute cerebral infarction were divided into two groups randomly.At the basic of routin treatment for the twe gyoups,GM1 group was treated with GM1 40 mg/d for 14 days and control group was treated with Citicoline 0.75 g/d for 14 days.The neurological deficit scores(NDS),activities of daily living(ADL) and adverse reactions were evaluated.Results After treatment,the scores of NDS and ADL were singnificantly decreased in twe groups than before treatment((P

BACKGROUND:Left ventricle volume or volume index and left ventricle mass or mass index are commonly used to evaluate left ventricle remodeling. Recently,real-time three dimensional echocardiography (RT3DE) has been attempted to evaluate left ventricle remodeling index (LVRI),and it is believed that LVRI can serve as new index to evaluate left ventricle reconstruction clinically. OBJECTIVE:To assess application of RT-3DE in evaluating left ventricular remodeling in patients with hypertension. DESIGN,TIME AND SETTING:Case-control observation was performed at the Department of Ultrasonography,First Hospital of Liaoning Medical University from September 2008 to September 2009. PARTICIPANTS:A total of 90 hypertension patients and 30 normal people were selected. The hypertension patients were divided into 3 subgroups according to interventricular septum,left ventricle myocardial thickness and end-diastolic diameter:normal configuration,concentric hypertrophy and eccentric hypertrophy groups with 30 cases in each group. METHODS:Three dimensional echocardiography of 90 patients and 30 controls was performed. Left ventricular end-diastolic volume (EDV),left ventricular end-diastolic epicardial volume (EDVepi) were measured by RT-3DE; left ventricular mass (LVM),left ventricular mass index (LVMI),left ventricular end-diastolic epicardial volume index (EDVI),LVRI were calculated and compared with two-dimensional echocardiography (2DE) Simpson biplane method. MAIN OUTCOME MEASURES:LVRI,LVMI,and EDVI detected by RT-3DE and 2DE Simpson biplane. RESULTS:LVRI,EDVI,LVMI measured by RT-3DE and 2DE were significantly different in hypertension patients (P 0.05). The LVRI measured by RT-3DE,2DE and EDVI,LVMI measured by 2DE were significantly correlated in normal control,normal configuration and concentric hypertrophy group (P 0.05). CONCLUSION:Real-time three-echocardiographic LVRI can serve as a new approach for evaluating left ventricular remodeling in clinic.

Objective:To investigate the clinical effectiveness analysis on biliary stent combined with 125I seed implantation in the treatment of malignant obstructive jaundice.Methods:98malignant obstructive jaundice patients undergoing percutaneous transhepatic biliary drainage requirement of biliary stent were divided into combined group(n=53) and simple group(n=45).Patients in combined group were taken biliary stent combined with 125I seed implantation,while in simple group were only taken biliary stent.All patients were followed up for 4 to 28 months.The changes of total bilirubin were recorded before percutaneous bile duct drainage,7 d,30 d and 90 d after biliary stent implantation.The recurrences of biliary obstruction of the two groups were recorded.The changes of T lymphocyte subsets in peripheral blood were detected before percutaneous bile duct drainage and after biliary stent implantation 7 d.The survival times of the two groups were compared.Results:All patients were successfully completed biliary stent implantation,surgical success rate was 100％.The total bilirubin levels of patients in combined group 30 d and 90 d after stent implantation were significantly lower than the simple group,the differences were statistically significant (P＜0.05).After surgery 7 d,the CD4 level and CD4/CD8 ratio in combined group were increased compared with before surgery,while in the simple group were declined,the differences were statistically significant (P＜0.05).Compared with the simple group,the CD4 level and CD4/CD8 ratio in combined group after surgery 7d were significantly increased (P＜0.05).2 cases (3.8％) of patients were recurrence of biliary obstruction,which were lower than 17 cases (37.8％) in the simple group,the difference was statistically significant (P＜0.001).The median survival time in combined group was 10.6 months,which was significantly longer than 7.5 months in the simple group,the difference was statistically significant (P＜0.05).Conclusion:Biliary stent combined with 125I seed implantation in the treatment of malignant obstructive jaundice might relieve the symptom of biliary obstruction,and helped to improve cellular immune function of patients and reduce the recurrence of biliary obstruction.It had great significance to improve the quality of life of patients and prolong the survival time.
