RESUMEN
Mentalizing is the vital cognitive basis of understanding of action intention.However,there are few studies on the complex relationship of them.The present study,firstly,discusses the concepts and the brain mechanisms of empathy and understanding of action intention,indicating the temporal dynamic features of mentalizing as well as understanding of action intention.Secondly,based on Intention Processing Network,the process of mentalizing in understanding of action intention is in hierarchy and division.During which,ventral medial prefrontal lobe plays a vital role on integrating and transforming the cognitive and affective information.Empathy and mentalizing transform into each other through ventral medial prefrontal lobe.So empathy probably mediates the relationship of mentalizing and understanding of action intention.Empathy,mentalizing and understanding of action intention can be integrated under the framework of hybrid models.Future studies should examine the relationship between empathy and understanding of action intention by empirical researches.
RESUMEN
Stress-related diseases are closely related to an abnormal cortisol secretion.Recent research implied that hair cortisol concentration which retrospectively records long-term cortisol basal level might possess superiority in the diagnosis of stresS-related diseases.This paper reviewed recent progresses in application of hair cortisol concentration in stress-related diseases (metabolic syndrome,obesity,cardiovascular disease,depression,PTSD,etc.) which showed abnormal long-term cortisol secretion in a wide range of situationS.This review proposed that the future research needs to take into accounts exclusion and/or balance of the influence factors,a longitudinal design in combination with acute-stress and chronic-stress biomarkers,and to develop new bio-markers related to hair cortisol concentration for study of stress related diseases,and establishment of standard protocols and clinical standards.
RESUMEN
<p><b>OBJECTIVE</b>To analyze interpersonal sensitivity level and influencing factors among patients in methadone maintenance treatment.</p><p><b>METHODS</b>From 2010 June to 2011 June, the research was performed in Center of Methadone Maintenance Treatment of Nanjing Baixia District Hospital. A total of 272 methadone maintenance treatment was studied using a self-designed questionnaire, interpersonal sensitivity scale in symptom check list (SCL-90), self-rating depression scale (SDS), self-rating anxiety scale (SAS). If interpersonal sensitivity level ≥ 2 points, it was positive. In this study, through independent sample t test, analysis of the social demographic characteristics, depression and anxiety, interpersonal sensitivity level. Non conditional logistic regression analysis was used to explore a variety of factors, and the relationship of these factors with interpersonal sensitivity.</p><p><b>RESULTS</b>The depression score, the anxiety score and the level of interpersonal relationship sensitivity in 272 methadone maintenance treatment (1.65 ± 0.51, 47.66 ± 8.58, 42.38 ± 9.40) was higher than the national norm (1.65 ± 0.51, 41.88 ± 10.57, 29.78 ± 0.46) (t values were 8.23, 17.63 and 22.27, respectively; all P values < 0.001). In 272 methadone maintenance treatment, the percentage of men was 75.0% (204/272) and the percentage of women was 25.0% (68/272). SDS score of male and female was (48.38 ± 8.30) and (45.90 ± 9.34) points (t = 5.67, P = 0.037); Aged 20-29, 30-39, 40-49 and ≥ 50 years old group, SDS scores were (48.26 ± 7.59), (47.73 ± 8.38), (47.79 ± 9.22) and (48.09 ± 6.33) points (F = 3.90, P = 0.046); According to the drug's time, divided into 1-3, 4-6 and ≥ 7 years group, SDS scores were (45.92 ± 7.47), (47.41 ± 7.57) and (48.07 ± 8.57) points (F = 4.49, = 0.039). SAS score of male and female was (41.21 ± 9.53) and (42.91 ± 9.42) points (t = 2.23, P = 0.043). The positive rate of interpersonal sensitivity was 47.1% (128/272). Multivariate analysis showed that, with SDS and SAS scores increased by 1, respectively, interpersonal sensitivity increased 23.23 (8.62-96.68) and 11.97 (6.42-19.27) points.</p><p><b>CONCLUSION</b>Interpersonal sensitivity level in methadone maintenance treatment was higher than normal and depression; anxiety and depression both were the risk factors of interpersonal sensitivity level.</p>

AIM: To explore the effect of EBV infection on growth and apoptosis of nasopharyngeal carcinoma(NPC) cell line.METHODS: NPC cell line CNE1 was directly infected by Epstein Barr virus (EBV). The expression of EBV-latent membrane protein 1 (EBV-LMP1) and bcl-2 were detected by immunohistochemistry method (LSAB). The growth of NPC cells was identified by MTT method. Apoptotic carcinoma cells were detected by flow cytometry analysis and the terminal deoxynucletidyl transferase-medicated dUTP-biotin nick end labeling (TUNEL) methods. RESULTS: EBV-LMP1 was positive in CNE1 infected by EBV(E-CNE1). Compared with CEN1, the growth of E-CNE1 apparently increased ( P
RESUMEN
AIM:To investigate the effect of Epstain-Barr virus latent membrane protein 1 (EBV-LMP1) on proliferation and cell cycle of nasopharyngeal carcinoma (NPC) cells. METHODS:The expression of EBV-LMP1 was detected by immunohistochemical method (LSAB). Proliferation of NPC cells was identified by MTT method. Cell cycle percentage was detected by flow cytometry analysis. RESULTS: OD value of EBV-LMP1 expressive NPC cells L-CEN1 was much higher than that of both EBV-LMP1 negative NPC cells V-CEN1 and CNE1 ( P 0.05).CONCLUSION:The expression of EBV-LMP1 on NPC cell might cause some change of cell cycle and enhance cell proliferation.
