ABSTRACT
Background and purpose: Natural killer/T cell lymphoma in poor effects, the production of multidrug resistance is one of the reasons to reduce the chemotherapy effect or failure. This study aimed to discuss the multidrug resistance associated protein 4 (ABCC4/MRP4) gene and multidrug resistance associated protein 5 (ABCC5/MRP5) gene expression in NK/T cell lymphoma SNK-6, YTS cell lines and NK/T cell lymphoma tissues, and the relationship between the level of ABCC4/MRP4, ABCC5/MRP5 gene expression and the clinical efifcacy. Methods:Real-time lfuorescence quantitative PCR (Real time-PCR) and immunohistochemical method (IHC) were used to detect the ABCC4/MRP4, ABCC5/MRP5 gene and protein expression. Results:Compared with the normal NK cells, ABCC4/MRP4 and ABCC5/MRP5 gene in SNK-6, YTS cell lines were highly expressed (P<0.05); Compared with rhinitis tissues, the expression of ABCC4/MRP4, ABCC5/MRP5 gene was higher in the NK/T cell lymphoma tissues (P<0.05);The expression level of ABCC4/MRP4 and ABCC5/MRP5 gene was negative correlation with clinical efifcacy (P<0.05). Conclusion: The expression of ABCC4/MRP4 and ABCC5/MRP5 gene affects the of clinical efifcacy of NK/T cell lymphoma.
ABSTRACT
Objective To explore the empathy deficits of adolescents with different types of conduct disorder. Methods The participants included 65 adolescents ( who met the DSM-Ⅳ criteria for conduct disorder)ranging from 13 ～ 18 in age,and 195 normal adolescents ranging from 13 ～ 18 in age. All participants were assessed by revised Basic Empathy Scale. 65 patients were divided into 4 subgroups according to symptoms: destructive-nondestructive subgroups and overt-covert subgroups. Results (1) Scores of cognitive empathy were lower in patients than normal controls ( (29.86 ± 4.72) vs ( 32.09 ± 4.94), P ＜ 0. 01 ). (2) There were significant differences in the levels of cognitive empathy between patients and controls (P＜0. 01 ). Scores of cognitive empathy were lower in destructive subgroup than controls ( (29.76 ± 4.46) vs ( 32.09 ± 4.94) , P ＜ 0.01 ). (3) There were significant differences in the levels of two dimensions and total scores of empathy between patients and controls (F=3.10 ～5.36, P ＜ 0.05 ). Scores of cognitive empathy were lower in overt subgroup ( 29.22 ± 3.77 ) and covert subgroup (30.21 ± 5.17 ) than controls (32.09 ± 4.94) (P＜ 0.05, P＜0.01 );and scores of affective empathy were lower in overt subgroup than covert subgroup ( (26.13 ±5.05) vs (29.50 ±4.16), P＜0.05 ). Total scores of empathy were lower in overt subgroup (55.35 ±7.09) than covert subgroup (59.71 ±7.58) and controls (60.04 ±8.50 ) (P＜0.05). (4) Logistic regression analysis showed that cognitive empathy was a protective factor for conduct disorders( OR = 0.43 ). Conclusion The cognitive empathy level of patients is significantly lower than normal students;and boys with different types of conduct disorder possess different empathic abilities when compared with healthy controls;and cognitive empathy is a protective factor for conduct disorder.
