Objective To investigate the empathic abilities and the association between empathic abilities and executive function in schizophrenic patients. Methods Empathy with the Interpersonal Reactivity Index-C (IRI-C) and executive function with Wisconsin Card Sorting Test (WCST) , Stroop Color-Word Task (Stroop), Spatial n-back Task (n-back) were applied to 74 schizophrenic patients and 69 healthy controls. Results Compared with healthy controls, schizophrenic patients showed significantly lower total scores ((46. 8 ± 10. 0) vs (51.5 ±9.7), P<0.01),and subscores in Perspective Taking ((9.5 ±4.2) vs (12.2 ±3.9) , P<0. 01), Fantasy ((12.5 ±4.2) vs (15.5 ±3.8), P<0.01) and Empathic Concern((15. 9 ±4.2) vs (17. 3 ±3.4), P< 0.05) ,but higher subscore((8.8 ±5. 1) vs (6.5 ±3.7), P<0.01) in personal distress of IRI-C. A significant difference(P<0.01) were fund on the scores of WCST, Stroop task and n-back task between schizophrenic patients and healthy controls. Pearson correlation analysis showed that the total scores of IRI-C was negatively correlated with the response administered (Ra), the number of responses errors (Re) and non-perseverative errors (nRpe) of WCST (r= -0.293, r= -0.253, r= -0.272, P<0.05) respectively, that empathic concern sub-score of IRI-C was negatively correlated with Ra, Re, perseverative responses (Rp) and perseverative errors (Rpe) of WCST (r= -0.326, r= -0.300, r= -0.294, r= -0.287, P<0.01 -0.05) respectively , but positively correlated with Rfp. of WCST (r=0.279, P<0.05), and that the fantasy subscore of IRI-C was negatively correlated with the reaction time of B part(r= -0.299, P<0.01) and C part (r= -0.322, P<0.01) of the Stroop task. Conclusion Schizophrenics have a general impairment of empathy and executive function,and affective empathy is related to the executive function, suggesting that the impairment of executive function maybe the one of pathological mechanism for the empathic deficit of patients with schizophrenia.

Objective:To investigate the protein expression of GTPBP4 in human hepatocelluar carcinoma (HCC) tissues and the influ-ence of GTPBP4 silencing by siRNA on the proliferation and cell cycle of HCC cell line Hep G2. Methods:Western blot analysis was per-formed to observe the protein expression of GTPBP4 in 24 cases of HCC tissues compared with their adjacent noncancerous liver tis-sues. Lentivirus-mediated RNA interference (RNAi) was used to silence GTPBP4 expression in Hep G2, and the infection efficiency was observed under a fluorescence microscope. The silencing effect was tested by Western blot and real-time PCR. After silencing the GT-PBP4 gene, cell proliferation was detected using CCK-8 assay, and the cell cycle was observed using flow cytometry. Results:(1) GT-PBP4 was overexpressed in 21 cases (87.5%) of HCC tissues (P<0.000 1). (2) After the lentivirus with GFP reporter infected the Hep G2 cells, 90%of the cells showed green fluorescence. LV-GTPBP4-RNAi effectively inhibited the expression of GTPBP4 at both mRNA (70%) and protein (67%) levels. (3) The proliferation ability of the LV-GTPBP4-RNAi group significantly decreased after 96 h (inhibition rate:54.51%). Flow cytometry showed that the LV-GTPBP4-RNAi group significantly increased at the G0/G1 phase, whereas the S phase de-creased and arrested at the G0/G1 phase. Conclusion:GTPBP4 overexpression in HCC tissues was associated with hepatocarcinogenesis and promoted tumor cell proliferation, but the specific molecular mechanisms remain to be investigated.
