Objective To explore the dose-effect,time-effect and safety of alteplase in the treatment of acute cerebral infarction.Methods One hundred and ten patients with acute cerebral infarction were selected,among whom 50 patients whose time window ≤3.0 h were divided into group A and group B by random digits table method with 25 cases each,and 60 patients whose time window 3.1-4.5 h were divided into group C and group D by random digits table method with 30 cases each.The patients in group A and group C received alteplase 0.6 mg/kg (maximum dose 60 mg) intravenous thrombolysis;the patients in group B and group D received alteplase 0.9 mg/kg (maximum dose 90 mg) intravenous thrombolysis.The national institutes of health stroke scale (NIHSS) scores before treatment and 1 h,24 h,7 d,30 d and 90 d after treatment were observed in the 4 groups.The therapeutic effect,complication incidence and fatality rate were compared.The prognosis was estimated by modified Rankin scale (mRS) score 90 d after treatment.Results The NIHSS scores 1 h,24 h,7 d,30 d and 90 d after treatment were significantly lower than those before treatment in the 4 groups,and there were statistical differences (P ＜ 0.05).The NIHSS score decreased significantly with time.There were no statistical differences in NIHSS score between group A and group B,group C and group D.There were no statistical differences in complication incidence and fatality rate 90 d aftcr treatment in group A and group D compared with group B and group C (P＞ 0.05).The rate of eusemia in group A was 76.00％ (19/25),in group B was 64.00％ (16/25),in group C was 43.33％ (13/30),and in group D was 53.33％ (16/30).And there were no statistical differences between group A and group B (x2 =0.620,P ＞0.05),and between group C and group D (x2 =0.069,P＞ 0.05).Conclusions The low dose alteplase is also effective and safe to acute cerebral infarction patients at time window ≤ 3 h.It is also effective and safe to acute cerebral infarction patients at time window 3.0-4.5 h at standard dose.

Objective To observe the factors affecting inadequate ST-segment resolution in patients with acute ST-segment elevation myocardial infarction after emergency percutaneous coronary intervention (PCI). Methods The patients with acute ST-segment elevation myocardial infarction undergoing emergency PCI were enrolled for study. According to the ratio of ST-segment resolution, 186 cases were divided into inadequate ST-segment resolution group (54 cases) and relatively adequate ST-segment resolution (132 cases). Clinical data of two groups were compared. The single factor and multiple Logistic regression analysis were performed to determine the factors influencing inadequate ST-segment resolution. Results Pre-infarction angina was protective factor of inadequate ST-segment resolution after emergency PCI (OR=0.361, 95%CI 0.131-0.994, P<0.05). Anterior myocardial infarction, attack-to-balloon time, Killip classification and white blood cell counts were risk factors of inadequate ST-segment resolution (OR=2.389, 95%CI 1.194-4.781;OR=1.655, 95% CI 1.082-2.532; OR=1.319, 95% CI 1.026-1.695; OR=1.184, 95% CI 1.004-1.396, P<0.05). Conclusions Patients with pre-infarction angina could reduce the risk of inadequate ST-segment resolution after PCI. Patients with anterior myocardial infarction,long attack-to-balloon time, Killip classification≥2 and high blood cell counts could increase the risk of inadequate ST-segment resolution, and earlier and more active clinical intervention should be taken.

With the developmetn of the medical humanistic education,more and more problems appear.The casualness of the medical humanistic curriculum,the monotony of the method of the evaluation,the insufficiency of the content,the inadequacy of the quality of the teachers,and the poor effect of the education are the factors affecting the development of our medical humanistic education.Through comparison of the humanistic education home and abroad,we find the key to these problems are the innovation of the curriculum and evaluation.

ObjectiveTo check the isolated heart by coronary angiography to discover the location, na-ture and degree of the coronary artery lesions more accurately and increase the comprehensive evaluation ability of cardiovascular disease.MethodsTen fresh isolated hearts with different causes of death were extracted and injected with barium sulphate as contrast substance by ring injector, then developed under Xper FD20 angiography equipment. The obtained pictures and image data were handled by three-dimen-sional angiography images with the software attached to the angiography equipment. The coronary artery tissues were HE stained and observed by microscope. The HE staining results were compared with the angiographic results.ResultsThe imaging data obtained from the 10 cases for examination showed 8 cases without coronary artery stenosis and 2 cases with Ⅲ, Ⅳcoronary artery stenosis, which were consistent with HE staining results of coronary artery organization and the both results were confirmed. ConclusionIsolated coronary angiography has an unique advantage for accurate grading of classification of coronary artery stenosis, examination of vascular malformation and tiny lesions, which can provide reference for the localization of small lesions and basis during the autopsy for identification conclusion.

Objective: To investigate the role of aldehyde dehydrogenase-2 (ALDH-2) for regulating human endothelial progenitor cells (EPCs) oxidative stress reaction and its mechanism. Methods: Human EPCs were isolated from peripheral blood of healthy adults and the cells were cultured in 4 groups:①Blank control group,②Alda-1 group, the cells were treated by 1μmol/L Alda-1, a speciifc activator of ALDH-2,③tBHP (10μg/ml) group and④Alda-1 pretreatment+tBHP group. EPCs reactive oxygen species (ROS) levels were evaluated by DCFH-DA staining, mitochondrial membrane potentials were detected by JC-1 method, migration capacity was measured by transwell chamber method and the activation of p38 signal pathway was examined by Western blot analysis. Results: Compared with Blank control group, ROS levels in tBHP group and Alda-1 pretreatment+tBHP group were (441.7 ± 24.8) % and (237.4 ± 12.0) %, allP<0.05. In Blank control group, tBHP group and Alda-1 pretreatment+tBHP group, the proportion of EPCs lost their mitochondrial membrane potentials were (5.7 ± 2.1) %, (81.7 ± 3.7) % and (37.4 ± 3.2) % respectively, allP<0.05; the number of EPCs migration were (108 ± 9)/HP, (22 ± 4)/HP and (67 ± 7)/HP respectively, allP<0.05. Compared with Blank control group, the activation of p38 signal pathway increased to (259.1 ± 7.7) % in tBHP group, while it was reduced to (186.4 ± 8.0) % in Alda-1 pretreatment+tBHP group. Conclusion: ALDH-2 could reduce ROS level in human EPCs, it may decrease mitochondrial membrane damage, protect migration which might be related to p38 signal pathway.

ObjectiveTo explore the genetic impact of TPH1 A218C,MAOA-uVNTR on abnormal frontal lobe of depressed patients and the interactions between the two polymorphisms using the method of genetic imaging.Methods28 patients with major depression and 34 healthy controls which were equal in sex,age,years of education and had negative family history of mental illness were recruited in our study.All paticipants underwent functional Magnetic Resonance Imaging (FMRI) in negative emotion recognition and were divided into different genotypes.Then frontal lobe was extracted as region of interest by WFU software into six subregions-bilateral superior frontal lobe,middle frontal lobe and inferior frontal lobe.ResultsPatients (0.19 ± 0.01 ) and controls (0.15± 0.05 ) with TPH1 AA genotype showed increased activation in left inferior frontal lobe than patients and controls with AC or CC genot.Patients with AA genotype showed increased activation in right inferior frontal gyrus(0.28 ±0.07) than other five groups as well.Patients with MAOA-H genotype showed increased activation in right middle frontal gyrus(0.15 ±0.06),left inferior frontal gyrus(0.18±0.02) than patients and controls with L genotype.Superimposition of TPH1 A218C and MAOA-uVNTR exsited in abnormal function of left inferior frontal gyrus(F=4.98,P =0.047 ).Patients with AA and H genotype showed increased activation in this area significantly than other patient group.ConclusionDifferent genes in serotonin system can affect brain function through a common 5-HT feature.

BACKGROUND: It has been reported tbat there are rich expressions of serotonin transporter (5-HTT) in the cortical and limbic regions related to emotion and behavior in cerebrum. Regulation of the intensity and persistence of serotonergic nerve response can change the serotonergic neurotransmission, meanwhile, 5-HTT is also an important target for selective serotonin reuptake inhibitors (SSRIs).OBJECTIVE: To observe whether there is a correlation of 5-HTT gene polymorphism with plasma level of 5-HT and the clinical response of SSRIs in the population of Nanjing area.DESIGN: A case-control observation.SETTING: Department of Psychiatry, Brain Hospital of Nanjing Medical University.PARTICIPANTS: Totally 132 inpatients with depression in the Department of Psychiatry, Brain Hospital of Nanjing Medical University and 100 volunteer healthy blood donors were taken as the observational subjects between January 2001 and December 2003.METHODS: The genotype was analyzed with polymerase chain reaction (PCR) polymorphism analysis in the patients with depression and healthy subjects; plasma level of 5-HT was analyzed with high performance liquid chromatography-electrical chemistry detector (HPLC-ECD); and the clinical response to the antidepressants were assessed with Hamilton depression rating scale (HAMD).MAIN OUTCOME MEASURES: The analytical results of 5-HTT genotype frequency and allele frequency in both groups, and the relationship between 5-HTT genotype and plasma level of 5-HT before and after SSRIs treatment were observed.RESULTS: Blood samples were collected from all the 132 patients with depression and 100 normal healthy subjects, and they all finished the scale test and entered the analysis of results. ① There were no significant differences between the depression group and normal control group in the 5-HTT gene genotype frequencies (LL: 24.2%, LS: 44.7%, SS31.1%; LL:29.0%, LS: 47.0%, SS: 24.0%, x2=1.405 8, P ＞ 0.05) and allelefrequencies (L:46.59%, S: 53.41%; L: 52.5%, S: 47.5%, x2=0.696 2, P ＞ 0.05). ② The total score of HAMD had significant differences before treatment among the depressive patients of different genotypes (F=6.48, P=0.002 1). After 4-week treatment of SSRIs antidepressants, the total score of HAMD was significantly decreased, and there was significant difference in the decrease of score (F=3.38, P= 0.037). ③ The plasma level of 5-HT had significant differences before treatment among the depressive patients of different genotypes (F=5.38,P= 0.005 7). After 4-week treatment of SSRIs antidepressants, the plasma level of 5-HT was increased, and the increased level was significantly different among different genotypes (F=23.55, P ＜ 0.01).CONCLUSION: The 5-HTT polymorphism may be not associated with the attack of depression, but with the severity of depression and the clinical responses of SSRIs in the population of Nanjing area, and the genotype in this area may become a reference index for the realization of individualized treatment in patients with depression.
