Objective To explore the characteristics of semantic priming effects in Chinese words with different association strength in patients with aphasia by auditory stimulation.Method Stimulus-response word pairs with different association strength including strong,moderate,weak,and no association categories were chosen from word association thesaurus as experiment materials.Both patients with aphasia(n=11)and normal subjects (n=16)were requested to finish an auditory lexical decision task for target words.Semantic priming effects were investigated by means of measuring reaction time(RT)and error rate of each word-pair.Results In patients with aphasia and normal subjects,the mean RTs were significantly shorter in strong,moderate and weak association strength words than in no association strength words(patients with aphasia(1270.20±47.70)ms,(1340.50±266.25)ms,(1429.70±317.07)ms vs(1549.00±325.87)ms,P<0.05 and normal subjects(1140.2±274.48)ms,(1196.50±284.06)ms,(1262.10±274.31)ms vs(1391.20±315.68)ms,P<0.05).In strong,moderate,and no association strength words,the mean RTs were no significant differences between two groups.In the weak association strength words,mean RTs were significantly longer in patients with aphasia than in normal subjects((1429.70±317.07)ms vs(1262.10±274.31)ms,P<0.05).In two groups,mean error rates were significantly less in strong,moderate and weak association strength words than in no association strength words(patients with aphasia:7.73±6.07,4.55±7.23,6.82±8.15 vs 14.09±12.41,P<0.05 and normal subjects:3.44±4.37,2.81±3.64,5.31±5.91 vs 10.94±11.14,P<0.05).However,in strong association strength words,mean error rates were significantly higher in patients with aphasia than in normal subjects(7.73±6.07 vs 3.44±4.37,P<0.05).In moderate,weak and no association strength words,there were no significant differences between two groups.Conclusion The patients with aphasia follow gradient of the association strength words like normal subjects and have semantic priming effects in the strong,moderate association strength words.

Objective To explore the effectiveness of the timed up and go test (TUGT) and the maximum walking speed test (MWST) in evaluating stroke patients' motor function.Methods Twenty-two stroke patients were assessed using the TUGT and MWST,and the temporal-spatial parameters of their gait were also assessed.The correlations among the TUGT times,walking speed and the gait parameters were quantified using Pearson correlation coefficients.Results The TUGT time was (18.57±7.41) s,significantly correlated with step length and velocity (P<0.05).Walking speed showed a significant positive correlation with step length,velocity and step length (P< 0.05).The TUGT times were negatively correlated with walking speed (r=-0.712,P=0.000).Conclusion The MWST and TUGT both can assess stroke patients' motor function effectively.

CX-conjugated antigen(BSA-CX) were produced by methods of EDC.The spleen cells of BALB/C mouse immunized by BSA-CX were fused with SP2/0 plasmacytoma cells using PEG4000,and selected cultured with HAT and HT medium.A hybridoma cell line of 2H8-B1-F4 was secreened for specificity to CX,and cloned by limited dilution method for 3 times,which secrete high affinity and stable monoclonal antibodies against CX with indirect ELISA. The antibody was characterized by IgG1 isotype, the titers of antibody in cell supernatant and ascites were 1∶1000 and 1∶4?10~5,respectively.The mAb against CX was selective toward dicloxacillin, oxacillin with cross-reactivity of about 19.6% and 21.3%,which can be used to detect CX residues by competitive ELISA.

AIM: To observe clinical efficacy of Tanreqing Injection (Radix Scutellariae, Bear gall powder, Ram's horn, Flos lonicerae japonicae and Fructus forsythiae) in treatment of patients with acute attack of bronchial asthma. METHODS: One hundred and seven patients with an acute asthma were randomly assigned into two groups: a treatment group (n=52, treated by Tanreqing Injection for 10 d in addition to the routine medications) and a control group (n=55, treated by routine medications). The serum levels of ET and TNF-α were determined by radioimmunoassay before and after treatment, respectively. RESULTS: Before treatment, there were no significant differences in the content of serum ET and TNF-α between the treatment group and the control group. However, after 10 d of treatment, the levels of ET and TNF-α inthe treatment group were significantly lower than those of the control group (P<0.01), and clinical efficacy of the treatment group was superior to the control group. CONCLUSION: Inhibitionof ET and TNF-α secretion and intervention inflammatory response might be one of mechanisms of Tanreqing Injection in treatment for acute asthma.

AIM: To study the protective effects of n on -mitogenic human fibroblast growth factor (nm-haFGF) on cardiomyocytes injured b y reactive oxygen free radicals. METHODS: The cardiomyocytes were isolated from neonatal SD mouse by trypsin digestion. The cardiomyocytes injury model was established by expos ing the cells to hydrogen peroxide (H 2O 2), and the injury status in cardiomy ocytes were evaluated by examining the cellular viability, measuring cell apopto sis and observing the change of cellular morphology. nm-haFGF was added to the c ulture medium, and the changes of cellular viability, superoxide dismutase (SOD) , malondialdehyde (MDA) and celluar apoptosis were observed. RESULTS: A dose-dependence relation between the concentration of H 2O 2 and the cardiomyocytes injury was observed. 10-80 ?g/L nm-haFGF dose -dependently increased cardiomyocyte viability and the general SOD activity, as well as decreased the content of MDA and the quantity of cardiomyocyte apoptosis . CONCLUSION: The higher the concentration of H 2O 2, the mor e serious the cardiomyocyte injury. nm-haFGF may have a good protective effects on cardiomyocytes treated with H 2O 2.

OBJECTIVE:To observe the efficacy and safety of tadalafil combined with tamsulosin in the treatment of erectile dysfunction(ED) patients after four area division plasmakinetic enucleation of prostate (FPKRP). METHODS:Seventy patients with ED after FPKRP were randomly divided into control group and observation group,with 35 cases in each group. Both groups received FPKRP;control group was given Tamsulosin capsule 0.2 mg orally,once a day,1 d after surgery;observation group was additionally given Tadalafil tablet 10 mg,once a day,on the basis of control group. Both groups were treated for 3 months. Clini-cal efficacies of 2 groups were compared;international prostate symptom score,the levels of prostate specific antigen,the maxi-mal urinary flow rate,international erectile function questionnaire-5 score,life quality score and ADR were also compared before and after treatment. RESULTS:The total response rate of short-term therapy in observation group was significantly better than con-trol group,with statistical significance(97.14% vs. 71.43%,P<0.05). Before treatment,there was no significant difference be-tween 2 groups in terms of international prostate symptom score,the maximal urinary flow rate,international erectile function ques-tionnaire-5 score and life quality score(P>0.05). After treatment,international prostate symptom score and life quality score in 2 groups were significantly lower than before treatment,and the observation group was significantly lower than the control group;the maximal urinary flow rate and international erectile function questionnaire-5 score were significantly higher than before treat-ment,and the observation group was significantly higher than the control group,with statistical significance(P<0.05). There was no statistical significance in the levels of prostate specific antigen between 2 groups before and after treatment (P<0.05). There was no statistical significance in the incidence of ADR between 2 groups(P>0.05). CONCLUSIONS:For patients with ED after FPKRP,tadalafil combined with tamsulosin can effectively improve erectile function,relieve the lower urinary tract symptoms and improve the quality of daily life with good safety.
