Stroke is one of the diseases that seriously threats the health of the elderly, and atherosclerosis is the main cause of ischemic stroke. Became it is closely associated with stroke, carotid carotid atherosclerosis has been one of the research hot spots in neurology. In recent years, the development of MRI techniques has provided a new approach for the qualitative and quantitative analysis of atherosclerotic plaque, and has reflected its unique superiority, This article reviews the applications of MRI in the evaluation of carotid atherosclerotic plaques.

As a marker of cerebral microangiopathy with a hemorrhagic tendency, the occurrence of cerebral microbleeds (CMBs) in various cerebrovascular diseases and its significance are increasingly receiving attention by the researchers and clinicians both from foreign and domestic, This article reviews the pathogenesy and imaging diagnosis, the correlations between CMBs and spontaneous intracerebral hemorrhage, ischemic stroke and cerebral amyloid angiopathy, as well as the guiding significance in thrombolysis, anticoagulation and antiplatelet aggregation therapy in ischemic stroke.

Objective The purpose of the present study was to develop an animal model of type II diabetic coro-nary heart disease in Zuker diabetic fatty ( ZDF) rats.Methods The ZDF rat model of type II diabetic coronary heart disease was prepared by high-fat diet feeding combined with continuous injection of isoprenaline hydrochloride (ISO) in a dose of 1 mg· mL-1 for 10 consecutive days.Serum creatine kinase (CK), and creatine kinase izozyme (CK-MB), ST segment in electrocardiogram ( ECG) and myocardial pathological changes were detected to evaluate the rat model.Results CK of both the control and model groups was gradually increased with ISO injections, while CK-MB increased first and then decreased.The ST segment in ECG part II had significant changes.The pathological examination found that about half of the myocardial cross section in the model group was necrotic after injections of ISO for 5 days and more than 3/4 of the my-ocardial cross section was necrotic after injection of ISO for 10 days.The results indicated that ISO caused myocardial inju-ry in ZDF rats.Conclusions The variation of CK-MB, CK, ST segments in ECG and myocardial necrosis indicate that the model is successfully established.The use of high-fat diet combined with continuous injection of isoprenaline hydrochlo-ride in a dose of 1 mg· mL is a simple way to develop a Zuker diabetic fatty rat model of type II diabetic coronary heart dis-ease.

[Objective] Systematic review was carried out in quality analysis of literature of Shuang Huanglian Injection (SHI) for acute respiratoiy infections ( ARI) . [Methods] Database was set up according to the principles of clinical epidemiology and evidence-based medicine and the evaluation scale for ARI. The data was managed by descriptive analysis and uniformity test. [Results] In 49 clinical reports, 42.16% adopted the randomized and controlled method but the quality was not so good; the criteria of inclusion and exclusion was absent or not standardized in most of the reports; blinded method was adopted scarcely; drop-out and missed cases were rarely mentioned while adverse effects were reported usually. [Conclusion] The design of clinical study of SHI for ARI has been improved in recent years but there is still a lot of inadequany.

Objective To evaluate the clinical value and effectiveness of ultrasound screening for fetal chromosomal abnormalitie in the middle and late pregnancy. Methods Fetuses who were detected with abnormal ultrasound findings during the middle and late pregnancy, and high risk of maternal serum screening underwent amnioeentesis or eordocentesis for fetal chromosome karyotypes. Results (1) A total of 31 cases with fetal malformation diagnosed by ultrasound were analysed for fetal chromosome karyotypes, and 8 (25.8%) cases were proved with fetal abnormal chromosome karyotypes. There were 3 cases of cervical springwater cyst accompany with edema,and all were fetal abnormal chromosome karyotypes. There were 3 cases of cervical pachyderma,and 2 were fetal abnormal chromosome karyotypes. There was one case with multiple malformations, one with Dandy-Walker malformation and one with holoprosencephaly malformation,all were revealed fetal abnormal chromosome karyotypes. (2) A total of 516 cases with high risk of Down's syndrome and trisomy 18 by maternal serum screening were analysed for fetal chromosome karyotypes,and 14(2.710%) cases were proved with fetal abnormal chromosome karyotypes, which include 7 cases of Down's syndrome and 7 cases of other fetal abnormal chromosome karyotypes. (3) A total of 544 (516 + 28)cases with high risk by the combination of ultrasound and maternal serum screening were analysed for fetal chromosome karyotypes, and 21 (3.86%) cases were proved with fetal abnormal chromosome karyotypes, the rate of detection higher than only maternal serum screening 42.43%.Conclusions Fetal structure abnormalities were the effective ultrasound signs for fetus chromosomal abnormalities screening in the middle and late pregnancy. The combination of ultrasound and maternal serum screening can improve the rate of fetus chromosomal abnormalities screening and be an effective way to retrieve false-positive and lower risk of maternal serum screening.

Objective To observe the normal configuration and size of the third ventricle in the second and third trimester fetuses in a normal population by ultrasonography. Methods The third ventricular width and configuration were obtained by antenatal ultrasonography in 765 fetuses with gestational age between 27 weeks and term.The relationship Between the width and the gestational age was analyzed.Results The third ventricle width 0～3 mm and showed the increased tendency; the correlation coefficient ( r ) between the width of the third ventricle and the gestationl week was 0.473 ( P＜0.01).The third ventricle was seen as a single echogenic line in 8(4.8%) of 165 fetuses, 145(61.5%) of all fetuses had parallel echogenic lines outlining a fluid-filled lumen, the V-shaped configuration of the third ventricle was seen in 12(7.3%) of the fetuses.Conclusions The third ventricle width shows the increased tendency in the second and third trimester.The parallel echogenic line becomes the prominent ultrasonography appearance in the second and third trimester fetuses.It's usefull to observe the normal ultrasonic apperance of the third ventricle in diagnosing the fetal central nervous abnormities.

Objective To explore the computed tomography (CT)manifestations of adrenocortical oncocytoma (ACO)for better understanding the disease and improving its diagnosis accuracy.Methods The CT manifestations of 9 cases with adrenocortical onco-cytomas confirmed by surgery were retrospectively reviewed and compared with pathological results.Results Five of cases were lo-cated in left side while 4 cases were in right side.Well defined and round or oval border could be found in all the cases.Of all the ca-ses,3 cases were solid lesions with equal density,< 3 cm in diameter,and mild consistent intensification after enhancement.Cystic lesion was detectd in 6 cases with > 3 cm in diameter.The mixed cystic and solid components with polycystic changes could be found on CT image,and remarkable intensification on solid lesion while no intensification on cystic lesion after the enhancement. Moreover,patchy or cotton-like shape could be found on solid lesion in 4 cases and 1 case with island like intensification;reticular pattern could be found in the central of lesion in 3 cases and 1 case with stellate shape.Pathological observation showed that the on-cotytomas were comprised of cells with abundant eosinophilic cytoplasm and necrotic and fibrous capsule without pathological mitosis could be found in some of lesion.Conclusion The characteristic CT features of adrenocortical oncotytoma has a worse specificity,its diagnosis was dependent on pathologic examination.

Objective To investigate the relationship of fasting serum FFA composition with central obesity, hypertension, insulin resistance, levels of serum zinc and age, gender-related differences. Methods Serum FFA were determined by high performance liquid chromatogram in 232 commuity|based subjects aged between 35 and 55 years: 109 hypertensives, 123 normotensives. Results Multivariate stepwise linear regression models and correlation analysis showed that serum FFA composition (including levels of n3PUFA, P/S ratio, C20:5/C18:3, C22:6/C20:5 and C20:4/C18:2 ratio) were linearly correlated with waist/ hip ratio, insulin sensitivity index, levels of serum zinc and related to the habit of diet (all P

Objective To investigate the incidence,distribution patterns,and influencing factors of cerebral microbleed (CMB) in Chinese adult patients with moyamoya disease.Methods Thirty consecutive patients with moyamoya disease confirmed by digital subtraction angiography from the Nanking Stroke Registry Program were included.All patients performed conventional MRI sequences (3.0 T) and susceptibility-weighted imaging.The clinical data,such as medical history,systolic blood pressure,diastolic blood pressure,mean arterial pressure,and white matter lesions were collected.Their fasting blood glucose levels and fibrinogen levels were detected.The numbers of CMB lesion,distribution information,and their relationship with various clinical parameters in patients with moyamoya disease were analyzed.Results Among the 30 subjects included,14 CMBs were detected in 10 patients from 11 hemispheres.The distribution of the lesions was mainly in deep brains (71.4%),especially in the periventricular white matter (50.0%).There was no statistical difference in age,gender,hemorrhage symptoms,blood pressure,white mater lesions,and plasma fibrinogen levels between the CMB positive group and CMB negative group.However,the fasting blood glucose levels in the former was significantly higher than those in the latter (8.0 ± 4.1 mmol/Lvs.4.8 ± 0.4 mmol/L;P =0.035).Multivariate regression analysis showed that the increased fasting blood glucose level was an independent risk factor for the occurrence of CMBs in adult patients with moyamoya disease (OR = 10.992,95% CI 1.325-91.218;P=0.026).Conclusions The CMB lesions are susceptible to Chinese adult patients with moyamoya disease in deep brains,especially in the periventricular white matter.The fasting blood glucose level may influence the incidence of CMBs in patients with moyamoya disease.

Objective To investigate the impulsivity and aggressiveness characteristics of patients with hepatolenticular degeneration (HLD) and its relationship with brain structure.Methods The Chinese version of the Barratt impulsiveness scale,11 version (BIS-1 1-C) and Buss-Perry aggression questionnaire (BPAQ) were assessed in 78 patients with hepatolenticular degeneration(HLD group) and 86 normal adults (health control group).HLD patients were examined by 3.0T magnetic resonance imaging (MRI).The differences in impulsivity and aggressiveness of the two groups were compared,and the relationship was analyzed between impulsivity,aggressiveness and different brain structures in patients with HLD.Results The total impulsive score,unplanned factor score,the total aggressive score and anger factor score of patients with cerebral HLD (61.74±9.82,26.08±5.06,82.71 ± 15.92,20.06± 5.74,respectively) were higher than those in patients with hepatic HLD (56.73±7.11,23.02±4.20,72.84± 11.15,16.64±5.01,respectively),and health control group(52.19±7.53,21.50± 3.93,64.64±9.83,14.27 ±4.38,respectively),and the differences were significant (F=3.193,4.646,11.830,8.270,all P＜0.05).Total impulsive score was positively correlated with aggressive score and physical aggression in HLD group(r=0.299,0.290,both P＜0.05).Unplanned score was positively correlated with aggressive total score (r=0.324) and physical aggression (r=0.320) in HLD group (P＜0.05).Frontal lobe injury was the influencing factor of total impulsive score(B=10.263,95％CI=0.467-19.946,P=0.008),attention score(B=2.837,95％CI=0.382-5.600,P=0.010) and unplanned factor score (B=3.977,95％ CI=0.848-8.502,P=0.046).Thalamus injury was the influencing factor of aggressive total score and its factor score.Caudate nucleus injury was the influencing factor of aggressive total score (B=10.030,95％ CI=3.351-18.039,P=0.017) and physical aggression score (B =4.432,95％ CI=1.193-7.729,P=0.016).Conclusion Patients with HLD have higher impulsive and aggressive tendencies,which are mainly manifested in unplanned impulsive and anger tendencies.Brain injury may be an important factor affecting impulsiveness and aggression in patients with HLD.Impulsiveness is related with frontal lobe injury and aggression to thalamus and caudate nucleus injury.Impulsiveness and aggressiveness in patients with HLD are not caused by damage to isolated brain areas,but are related to damage to multiple brain areas.
