ABSTRACT
Objective To explore the correlation between verbal memory and working memory in patients with alcohol dependence (AD).Methods A total of 40 patients with AD and 40 health controls were included in this study.N-back task was used to evaluate the verbal working memory.20 sets of phrases were used to evaluate long-term verbal memory.Results Correct number of verbal memory in AD group ((5.15±0.92)times) was lower than that of HC group ((7.35±3.07) times) after one-week baseline test,and the difference was statistically significant (t=4.344,P＜ 0.01).Compared with HC group ((1 436.37±192.50) ms,(1.08±0.89) times,(4.00±0.85) times,respectively),AD group((1 535.40± 192.50) ms,(1.90± 1.57)times,(2.60± 1.39)times) showed significantly impaired reply reaction time of 2-back,error number of 1-back and 2-back (t=-2.112,P=0.038;t=-2.899,P=0.005;t=-5.433,P＜0.01).The error number of 2-back task in AD group was negative correlated with verbal memory after one-week baseline test (r=-0.427,P=0.006).Conclusion The verbal memory is impaired in AD patients.Long-term verbal memory damage have a certain correlation with working memory.
ABSTRACT
Objective To analysis effect of breviscapine on serum and copeptin, NT-proBNP, HIF-1αand IMA in patients with acute ischemic brain vascular disease.Methods 42 patients who were diagnosed with acute ischemic brain vascular disease were collected and randomly divided into experimental group and control group, each group had 21 cases.All patients were given conventional treatment of Western medicine, on this basis, control group was given vinpocetine injection 20 mg, once daily intravenous drip;experimental group given Dengzhan flower Suting injection 20 mg, once daily intravenous drip; continuous treatment for 2 weeks.Before and after the treatment, the serum levels of copeptin, HIF-1α, NT-proBNP and IMA were detected in two groups.ResuIts Compared with control group, patients in experimental group treatment effect was better, as follows: serum copeptin content decreased significantly ( P<0.05 ) .Serum NT-proBNP levels decreased significantly ( P<0.05 ) .Serum levels of HIF-1αcontent decreased significantly (P<0.05).Serum ACB value increased significantly (P<0.05).ConcIusion Breviscapine can reduce the acute ischemic brain vascular disease patients serum copeptin, NT-proBNP, HIF-1αand IMA content, and has good therapeutic effect in patients with acute ischemic cerebral vascular disease.
ABSTRACT
Objective To study the attentional deployment strategy of emotion regulation and its processing mechanisms in alexithymia.Methods 21 alexithymia subjects and 22 normal subjects completed attentional deployment task.The reaction time(RT) and accuracy were recorded automatically and the event-related potentials (ERPs) were recorded by neuroscan system.Results ①From the behavioral results,the differences of RT and accuracy to neutral pictures ((1840.17±204.44) ms vs (1845.17±252.97) ms;(0.859±0.073) vs (0.884±0.068)) and negative pictures ((1888.94±200.09) ms vs(1890.38±263.72) ms);(0.845±0.088) vs (0.845±0.091)) in calculation task between two groups were not statistically significant(all P＞0.05).The differences of RT and accuracy in emotion task were not statistically significant(P＞0.05).②In RT and accuracy,the task main effects were statistically significant(F(1,42) =637.40,P＜0.01;F(1,42)=15.00,P＜0.01),the emotion main effects were statistically significant (F(1,42)=30.23,P＜0.001;F(i,42)=47.87,P＜0.01),the interaction effects of task and emotion were statistically significant(F(2,41) =5.20,P＜0.05;F(2,41)=6.01,P＜0.05).③The differences between two groups in P3 amplitude induced by neutral pictures and negative pictures in calculation task were not statistically significant(P＞0.05).P3 amplitude induced by negative pictures were siguificantly greater than those induced by neutral pictures in emotion task((-0.138±0.463) μV vs (0.789±0.541) μV).Conclusion The attentional deployment can effectively regulate the negative pictures processing and occur in the late stage of the picture processing.No attentional deployment defects in alexithymia.
ABSTRACT
Objective To investigate the attention network in patients with obsessive-compulsive disorder (OCD) and generalized anxiety disorder (GAD).Methods 31 GAD patients,31 OCD patients and 30 healthy controls (HC) were tested with attention network test.Results There were significant differences in the main effects with respect to the alerting network(15.87±5.24,26.77±4.33,34.87±3.47) (F=4.619,P=0.012)) and the executive network(114.84±9.64,122.45±5.57,96.57±5.45) (F=3.388,P=0.038) among the OCD,GAD and HC groups.The three groups did significantly differ in RT of the attention network (F=19.808,P=0.000).For the HC group,there was significant main effects with respect to cue conditions(F=29.699,P=0.000).There was a significant correlation between the executive network and Hamilton anxiety scale (r=0.351) and also a significantly negative correlation between the alerting network and Hamilton depression scale (r=-0.267).Conclusion There are attention network damages in patients with OCD and GAD,which may be involved in the impairment of emotion.
ABSTRACT
Aim To explore the clinical significance of the vWF in the patients with essential hypertension(EH). Methods vWF were measured with enzyme linked immunoabsorbent assay(ELISA) in 103 EH patients and 30 normal controls. The vWF values were compared by age ,gender,and stages of hypertension. Results There were markedly rise in EH patients than that in the normal controls. The vWF was increased with the age and stage of hypertension. The highest vWF was found in male over seventy years. Conclusion vWF may serve as an indicator of injury of endothelium. A positive correlation between endothelium lesion and age was found.
