Objective To explore the correlation between cognitive ability and motor ability in stroke patients.Methods 30 stroke patients were assessed with the 3 m Timed Up and Go Test (TUG). The anticipated time by patients and the actual time were recorded, and their difference was caculated, named as the cognitive error. They were also assessed with Trail Making Test-Part A (TMT-A). The actual time of TUG, cognitive error and the time of TMT-A was compared among different groups of Brunnstrom stage of lower limb, and their correlation was analyzed. Results There was a significant difference between the actual time of TUG between Brunnstrom stage Ⅲ and Ⅴ (F=4.600, P<0.05). There was positive correlation between actual time of TUG and cognitive error（r=0.844, P<0.01）, time of TMT-A and cognitive error（r=0.508, P<0.01）, time of TMT-A and actual time of TUG （r=0.414, P<0.05）. Conclusion Motor ability of stroke patients can be influenced by deficient attention and motor cognition.

Objective To observe clinical effects of treating subarachnoid hemorrhage with intracranial aneurysm interventional embolization combined with Chinese herbs of removing blood stasis and hemostasis. Methods 45 cases with subarachnoid hemorrhage were randomly reeurited into a control group and a treatment group. The control group was treated with intracranial aneurysm interventional embolization, and the treatment group was treated with intracranial aneurysm interventional embolization combined with Chinese herbs with the functions of removing blood stasis and hemostasis. The clinical effect was observed between the groups. Results The clinical effect in the treatment group was significantly higher than that of the control group (P< 0.05 ). Conclusion The treatment of subarachnoid hemorrhage with intracranial aneurysm interventional embolization combined with Chinese herbs of removing blood stasis and hemostasis is better than intracranial aneurysm interventional embolization exclusively.

Objective To observe the expression of acid-sensing ion channel la (ASICla) and to investigate the effect of intracellular Ca2 + concentration on focal cerebral ischemia in diabetic rats.Methods 108 male Wistar rats were divided into three groups:group A [rats with middle cerebral artery occlusion (MCAO)],group B [rats with MCAO and diabetes (DM + MCAO)],group C [rats with MCAO and diabetes treated with fasudil intervention (DM+ MCAO+ fasudil)] (n=36 each).Samples were obtained at the time points of 1,3,6 and 24 h after ischemia respectively (n=9).Models of MCAO and DM+MCAO were prepared.Rats in DM+MCAO+Fasudil group were treated with fasudil 1 mg/Kg by caudal vein injection after half an hour when DM+MCAO model successfully prepared.ASICla expressions were detected at different time points of ischemia in the 3 groups respectively.Ca2+ concentration in ischemia cortex cells were determined at different time points of ischemia in group B and C.Results ASICla expressions were gradually increased along with the ischemia time in group A and B (group A:0.71±0.10,0.80±0.11,0.86±0.08,0.93±0.09;groupB:0.86±0.11,1.05±0.51,2.42±0.08,2.78±0.04; all P＜ 0.05),and ASICla expressions at different time points were higher in group B than in group A (all P＜ 0.05).Ca2-concentration were gradually increased along with the ischemia time in group B (106.32± 18.6,137.84±14.32,151.94± 18.38,183.61±7.96,all P＜0.05).Compared with group B,the levels of ASICla expression and calcium current were reduced in group C.Conclusions The activation of ASICla increases calcium ion flow internal pathway leading to intracellular calcium overload,which may be one of the reasons for the aggravation of focal cerebral ischemia in diabetes.

Objective To investigate the changes of serum bilirubin level in elderly patients with acute cerebral infarction and its significance.Methods 164 hospitalized elderly patients,who suffered from acute cerebral infarction within 1 week after onset,were divided into 2 groups according to age:group A aged over 60 years(n=85) and group B aged 40-60 years(n=79),and 66 healthy subjects aged over 40 years were collected as controls(group C).Serum bilirubin levels in all subjects were determined.The ratio of pulse pressure over mean arterial pressure(PP/MAP) in group A and B was calculated.Nerve function scores in the three groups were detected before and after 2 weeks of treatment.Meanwhile,the data of risk factors including blood glucose,blood pressure,blood lipids,smoking and drinking in group A and B were collected.Results Compared with group C,serum total,direct,indirect bilirubin levels were increased in group A and B(both P＜0.01),and the change was smaller in group A than in group B(P＜0.05).The nerve function scores was lower in group A than in group B before and after treatment [(35.2±12.6) vs.(44.3±7.9),(40.7±9.1) vs.(51.3± 4.1),t=5.58,9.73,both P＜0.01],but PP/MAP and the numbers of risk factors were higher in group A than in group B [(0.46±0.06) vs.(0.38±0.06),93.01 vs.71.20,both P＜0.01].There were no significant correlations of serum total,direct and indirect bilirubin levels with nerve function scores in group A or B(all P＞0.05).Conclusions Serum bilirubin level is increased in patients with acute cerebral infarction,but the endogenous antioxidant capacity is decreased because of aging,multiple risk factors and more serious atherosclerosis in elderly patients,and the increment of bilirubin level is relatively smaller in acute cerebral ischemia,leading to the reduced protective effect against stress.Serum bilirubin level may influence the prognosis in patients with acute cerebral infarction.

Background Fibrin glue has been utilized to adhere the graft during the pterygium excision with conjunctival autografts.Several relevant clinical randomized controlled trial(RCT) and retrospective studies have been published abroad,but the samples for its effectiveness and safety issue of fibrin glue and suture are still underinvestigation.Objective Current study was to quantificationally assess the efficacy and safety of fibrin glue versus sutures in the application of pterygium excision with conjunctival autografts.Methods Based on established search strategy,a computerized literature search was conducted to identify all citations concerning the RCT for effectiveness and safety evaluation of fibrin glue and suture for the graft fixation during the pterygium excision with conjunctival autografts from MEDLINE ( from 2000 to October,2010 ),EMbase ( from 2000 to October,2010 ),Cochrane Central Register of Controlled Trials ( Issue 4,2010 ),CBMdisc ( 2000 to October 2010 ),CNKI ( 2000 to October 2010 ),and the relevant conference proceedings and references searched by hand was performed as supplement.The included literature was scored with Jadad table.The Cochrane Collaboration' s RevMan 5.0 software was used for the test of heterogeneity or test for overall effect.The effective indexes,such as operative duration,recurrence rate and complication,were evaluated by Meta analysis.Results Six RCTs involving 401 eyes of 377 participants were identified.These literatures were published with English in 2004-2010 from China,New Zealand,Sweden,Israel,Turkey and Malasia and the Jadad scores were 4-5.The quantitatively analysis revealed that fibrin glue appeared to short the operative time compared with suturing method (MD =14.23 ;95％ CI:- 16.18- 12.29;P=0.00) and drop the rate of recurrence ( RR =0.49,95％ CI:0.26 -0.95 ; P =0.03 ).No significant differences were found in the rate of postoperative graft dehiscence or absence (RR =3.41,95 ％ CI:0.85-13.68;P =0.08 ).Conclusions Fibrin glue shows the good effectiveness and easy application during the pterygium excision with conjunctival autografts.Long-term follow-up of multi-central RCTs with a larger number of cases are still needed to support this conclusion.

Flammulin, an anti-tumor protein, was purified from the aqueous extract of basidiomes of Flammulina Velutipes. Purified flammulin emulsified with Freund's adjuvant was injected subcutaneously into New Zealand white rabbits. After several immune enhancements, these animals were bled and sera were separated. Antiserum against flammulin in Western blots were applied to determine if flammulin be present in the liquid state culture or fruiting body. The result showed that anti-flammulin serum could recognize the aqueous extract of fruiting body in SDS-PAGE gels under the reducing conditions, no flammulin was detected in mycelia of Flammulina Velutipes.

Objective To identify the genetic loci associated with bipolar disorder in Chinese population by the ge?nome scan on chromosome 20 in bipolar disorder patients and healthy people from Shandong peninsula. Method Geno?typing was conducted on DNA pool samples of 104 bipolar disorder patients and 1000 controls using thirteen microsatel?lite markers on chromosome 20 spaced at intervals of approximately 10 cM and GeneMapper 4.0 software. CLUMP soft?ware was used to analyze multiallelic markers. Result Significant difference of allele frequencies was found at marker D20S186 (20p12.2) between patients and controls (P=0.022). Conclusion The data suggest that the D20S186 locus (20p12.2) is significantly associated with susceptibility to bipolar disorder in a Chinese Han population in Shandong pen?insula. Future studies should focus on the fine mapping of this region and assessment of candidate genes.

Objective To evaluate the accuracy of the fetal weight estimation system in terms of estimating the fetal weight.Methods The fetal weight estimation system developed by the Department of Electronic Engineering,Fudan University was applied to estimate the fetal weight in many hospitals,and the differences between the estimated results of the system and the actual weight of newborn fetuses,as well as the accuracy of the estimation system and the traditional estimation methods were compared.Results A total number of 610 cases were employed,with each case including the ultrasound images of fetus before birth,the corresponding measurement data and the newborn weight.The correlation coefficients between the weight of the newborn babies and the fetal parameters,which were measured by the estimation system in terms of the biparietal diameter,the head circumference,the abdomen circumference and the femur length,were higher than those obtained by manual annotations,with improvements of 0.08,0.17,0.09 and 0.05,respectively.The absolute error of the estimated weight of the system with respect to the actual weight was 44 g smaller than those estimated by traditional method,and the variance of the absolute error was 53 g smaller;while the corresponding absolute percentage error was 1.8％ lower,and the corresponding variance percentage was 1.5％ lower.Conclusions The fetal weight estimation system improves the accuracy of the prenatal ultrasound assessment and provides reliable information to clinical diagnosis.

Objective To assess the effects of fenofibrate on myocardial remodeling in obese rats by echocardiography.Methods Twenty-six SD rats were fed with high fat chow to establish twenty obese rats models,which were randomly divided into two groups:obesity group (OB group,n =10) and fenofibrate group(F group,n =10).The same week-old SD rats group (n =10) was also randomly selected as normal control group.F group was given fenofibrate 60 mg · kg-1 · d-1 for 8 weeks,the other groups were given normal saline.Echocardiographic scan was performed in each group at the beginning and ending of the experiment.Twenty-four weeks later,all rats were executed and the cardiac muscle was used to histological inspect.Results After the experiment,compared with the control group,the body weight,the ventricular thickness,interventricular septal thickness and the left ventricular mass in OB group were significantly increased than those of control group(P ＜0.01),the E/A ratio was significantly decreased(P ＜0.01).Histological detection showed that myocardial structure was disordered,and that interstitial collagen was deposited in the myocardium.Compared with OB group,the parameters all above in F group were significantly improved (P ＜0.01).Left ventricular mass from echocardiography correlated well with the results from pathologic specimen (r =0.98,P ＜0.01).Conclusions Fenofibrate has beneficial effects on preventing myocardial remodeling.By general echocardiography,the effects can be assessed comprehensively and accurately.
