Objective To investigate the changes of the serum high sensitive C-reactive protein (hs-CRP)level in patients with acute cerebral infarction (ACI) and study the relationship between hs-CRP level and ischemic stroke subtypes according to the trail of org10172 in acute stroke treatment (TOAST) criteria.Methods The serum hs-CRP was measured in 152 ACI patients by immunonephelometrical method. All ACI patients were classified into 5 major ischemic stroke subtypes based on TOAST criteria. And then the relationship between hs-CRP level and their TOAST subtypes were analysed.Results The percentage of each ischemic stroke TOAST subtypes of 152 patients was as following: stroke of undetermined etiology 41.45%, small-vessel occlusion 34.87%, cardioembolism 5.26%, large-artery atherosclerosis 15.79%, and stroke of other determined etiology 2.6%. Among 5 ischemic stroke subtypes, cardioembolism patients were related to the highest positive rate of hs-CRP(87.50%) and the highest hs-CRP level [(11.60?7.85)mg/L]. The hs-CRP level in large-artery atherosclerosis or stroke of other determined etiology were (10.77?4.27) mg/L or (6.45?3.25) mg/L respectively, Stroke of undetermined etiology and small-vessel occlusion subtypes were associated with the lowest positive rate of hs-CRP(38.10%, 37.74%) and the lowest hs-CRP level [(4.09?5.65)mg/L,(3.99?0.56)mg/L]. Apparently, other factors, such as age, systolic blood pressure, cholesterol, triglyeride, fasting blood sugar and fibrinogen, could also affect the hs-CRP level in serum(r=0.1640、0.2489、0.2066、0.1866、0.3029、0.2224,all P

Objective To investigate the protective effect of Edaravone on dopamine transporter in rat models of Parkinson disease.Methods Rat models of Parkinson disease were induced by injection 6-OHDA into right medial forebrain bundle. Edaravone at different doses (3.0 mg/kg, 1.0 mg/kg or 0.3 mg/kg) was injected intraperitoneally twice daily for two weeks. The same dose of normal saline was injected in the control group. One week after the treatment, the ?-radiation of rat bilateral striatum, cerebral cortex and cerebella cortex of each group was measured by a ?-counter and the brain tissue ID value was calculated.Results There was a significant difference of the radiation count in right striatum between the large dose group (0.47?0.06) ,medium doss group(0.37?0.02)and the control group (0.25?0.01)( P

Objective To investigate the pattern of fluctuations and clinical significance of fasting serum insulin(FINS) and C-peptide(CP) levels in patients with different subtypes of acute cerebral infarct(ACI) and its relationship with serum lipid. Methods FINS and CP were measured in 152 ACI patients by chemiluminescent immunoassay. All ACI patients were classified into 5 major ischemic stroke subtypes according to the trial of org10172 in acute stroke treatment(TOAST) criteria. And then the relationship between FINS and CP level and serum lipid in different TOAST subtypes were analysed. Results The percentage of each ischemic stroke TOAST subtype was as follow: stroke of undetermined etiology 40.13%, small-vessel occlusion 34.21%, cardioembolism 5.26%, large-artery atherosclerosis 15.79%, and stroke of other determined etiology 4.61%. Among 5 major stroke subtypes, large-artery atherosclerosis patients had the highest levels of FINS and CP. The levels of FINS and CP in small-vessel occlusion were (8.237?5.144) ?U/ml and (1.761?0.975)ng/ml,respectively. Stroke of other determined etiology subtypes were associated with the lowest levels of FINS and CP. Apparently, other factors, such as TC, TG, LDL, SBP, DBP, age and HDL, could also affect the levels of FINS and CP in serum. Conlusions Levels of FINS and CP varied in different subtypes of ACI. There was a significant correlation among insulin resistance, hyperinsulinemia(HIS) and lipid metabolic abnormality in ACI.

Objective To explore the quality of randomization of RCT in medical periodicals of China.Methods We designed a table of quality evaluation of RCT.and then randomly chose 137 articles entitled with "random control",which were published in 1995,2000,and 2005.Results Of the 137 articles,103 meet the requirement of this research.Of the 103 articles,99 didn't include the details of randomization (96.1%),100 didn't present the sampling methods(97.1%).Articles published in 1995 totally didnt include the introduction of randomized sampling And grouping methods, but the situation got beuer in 2000 and 2005.There was 63.1% included clear description of diagnostic criteria.Of remaining of 36.9%, 23.3% included either in drawing or excluding criteria,50.5% included both, and 26.2%included none,For grouping,69.9% included the introduction of the baseline of each group, and 30.1%didn't.Conclusions There were some problems in the RCT,such as lack of rigorous in randomization, incomplete in diagnostic,in drawing,and excluding criteria,and lack of clear introduction of the baseline.which revealed there were still much work needed to be done to improve the clinical research level in our country.

Objective To investigate the changes of multifocal electroretinogram ( mf-ERG ) in patients with Parkinson′s disease.Methods Forty-five Parkinson′s disease patients ( 70 eyes ) and 35 normal controls (60 eyes) enrolled in the Second Affiliated Hospital of Soochow University from February 2015 to February 2016 received mf-ERG examination and general ophthalmology examinations including best corrected vision acuity, slit-lamp test, fundus examination, intraocular pressure and vision field test. Results The amplitude density of P 1 wave in Parkinson′s disease patients was dramatically decreased in ring 1, ring 2 and ring 5 compared with the normal controls (amplitude density of P1 in ring 1:(100.58 ± 41.19) nV/deg2 vs (138.10 ±17.16) nV/deg2,t=5.086,P<0.01; amplitude density of P1 in ring 2:(21.93 ±7.46) nV/deg2 vs (37.56 ±9.39) nV/deg2, t=9.844, P<0.01; amplitude density of P1 in ring 5:(7.07 ±3.04) nV/deg2 vs (10.22 ±3.68) nV/deg2 ,t=4.924, P<0.01).The latency of P1 wave in ring 1, ring 3 in Parkinson′s disease patients was significantly higher than the control group (latency of P1 wave in ring 1:(42.72 ±8.09) ms vs (37.90 ±5.95) ms, t=-3.155, P<0.01;latency of P1 wave in ring 3:(41.20 ±7.63) ms vs (37.80 ±4.59) ms, t=-2.995, P<0.01).The implicit time of N1 wave in ring 1 in Parkinson′s disease patients was delayed , which had statistically significant difference compared with the normal controls ((21.92 ±7.87) ms vs (19.04 ±4.19) ms, t=-2.012, P=0.046).However, in the amplitude of N1 wave, there was no statistically significant difference between the two groups . Conclusions The vision function has already decreased in Parkinson′s disease patients , even before the vision acuity is normal .The mf-ERG test can find the changes of vision function in Parkinson′s disease patients, which are the decrease of amplitude density of P 1 , the latency of implicit times of P 1 wave and N1 wave in some regions of the retina .

Objective To explore the mechanism underlying the poor prognosis in cerebral infarction (CI) patients with low T3 syndrome by comparing the NIHSS scores in these patients with or without low T3 syndrome.Methods One hundred and sixty-two patients with CI,admitted to our hospital from January 2010 to December 2012,were chosen in our study; the levels of thyroid hormones,including triiodothyronine (T3),four iodine thyronine (T4),thyroid stimulating hormone (TSH),free Triiodothyronine (iT3) and free four iodine thyronine (fT4),were measured by radioimmunoassay.CI lesions and TOAST distribution were determined by cranial MRI,magnetic resonance angiography (MRA) or CT angiography (CTA),and carotid ultrasonography.NIHSS scores at the worst in cerebral infarction inpatients were detected.Results In the 162 patients with CI,29 patients (17.90％) were combined with low T3 symptom and 20 had fT3 level lower than the lowest normal level (2.63 pmol/L); and T4,fT4 and TSH levels were within normal limits.T3,fr3 and TSH levels in patients with low T3 symptom were significantly lower than those of patients without low T3 symptom (P＜0.05).The distribution of TOAST showed no significant difference between patients with low T3 symptom and patients without low T3 symptom (P＞0.05).In patients with large artery atherosclerosis-internal carotid artery,the NIHSS scores at the worst in patients with low T3 level were significantly higher as compared with those in patients with normal T3 levels (P＜0.05).Conclusion The neurologic impairment is more severe in large artery atherosclerosis-intemal carotid artery patients with low T3 level than those without low T3 level,which might be responsible for the poor prognosis of the illness with low T3 syndrome.
