ABSTRACT
Objective To explore the application of the ultraviolet spectrophotometry method in detecting colchicine poisoning serum to provide the basis for clinical diagnosis and treatment of colchicine poisoning.Methods 0.5 mL of serum was taken and added with the extract solution(chloroform∶methanol=95 ∶5)4.0 mL.The sufficient oscillation extraction and high-speed cen-trifugation were performed.Then the organic layer was taken into another test tube for drying by nitrogen.0.2 mL of methanol dis-solved residue was taken and blended.50 μL of the mixed solution was taken for conducting ultraviolet scanning.Results The max-imum absorption peak of serum colchicine was (351 ±1)nm,the concentration within 5.0-40 μg/mL showed linearity,the regres-sion equation wasY =0.050 2X +0.001 3,the correlation coefficient was 0.999 5,the recovery rate was 83.8% -102.8%,the rel-ative standard deviation:3.3% -4.8%.The intra-day and inter-day were 3.22%-4.74% and 3.45%-4.66%,the lowest detec-tion concentration was 1 .0 μg/mL.Conclusion This method is simple to operate,fast in analysis,accurate in the detection result, which provides a simple and accurate detection method for clinical diagnosis of colchicine poisoning.
ABSTRACT
Objective To investigate the expression of p27kip1, CyclinE, CyclinD1 in bladder transitional cell carcinoma (BTCC), and evaluate their relationship with turnout cell proliferation. Methods To study the expression of p27kip1, CyclinE and CyclinD1 protein in 41 cases of paraffin-embedded BTCC tissue and in 12 cases of cystitis tissues by immunohistochemical method SP. Results There was a negative relationship between p27kip1 expression and clinical stage and pathological grade.There was no relationship with lymph node metastasis (P>0.05). There was a positive relationship between CyclinE expression and clinical stage, pathological grade and lymph node metastasis (P<0.05). There was no relationship between CyclinD1 expression and clinical stage, pathological grade and lymph node metastasis (P>0.05). Conclusion The results of this study showed that the abnormal expression of p27kip1, CyclinE, may play important roles in the genesis and progression of BTCC. CyclinD1 may take activation in the early term of BTCC.
ABSTRACT
Objective:To develop an Emotional Intelligence Scale for Chinese pupils.Methods:Data were collected from a sample of 288 primary school students tested by the Emotional Intelligence Scale.Results:①Item analysis showed that the Emotional Intelligence Scale had satisfactory item discrimination.② The Emotional Intelligence Scale had a satisfactory reliability with a 0.90 test-retest reliability and the Cronbach's ? was 0.89.③The result of EFA had five factors,and the range of factor loading was between 0.40 and 0.77.The final revised questionnaire included 25 items,explaining 54.33% of the total variances.④The result of independent-sample t test showed significant gender differences in emotional intelligence.Conclusion:The Emotional Intelligence Scale for pupils has ideal reliability and validity.
ABSTRACT
Objective: To develop a Constructive Thinking Scale for Chinese pupils. Methods: Data were collected from a sample of 302 primary school pupils tested with the Constructive Thinking Scale. Results: ①Item analysis showed that the Constructive Thinking Scale had satisfactory item discrimination; ②The Constructive Thinking Scale had a satisfactory reliability with a 0.83 test-retest reliability, and the Cronbach’s ? was 0.88; ③The result of EFA had five factors, and the range of factor loading was between 0.36 and 0.75. The final revised questionnaire included 23 items, which could explain 53.13% of the total variances. The scale had an ideal criterion validity. Conclusion: The Constructive Thinking Scale for pupils has ideal reliability and validity, and can be used in assessing Chinese pupils’ constructive thinking .
ABSTRACT
0.40); ②The result of EFA had four factors: physical aggression, anger, hostility and substitution aggression. The range of factor loading was between 0.51 and 0.75; ③The Chinese version of BPAQ had a satisfactory reliability with a 0.92 test-retest reliability and the Cronbach’s ? was 0.84; ④There was significant gender difference in physical aggression, substitution aggression and the total aggression. Conclusion: The Chinese version of BPAQ is a reliable and valid instrument for measuring aggression of adolescents.
