Objective To investigate post-traumatic stress disorder (PTSD) and life quality (QOL) of children and adolescents with cancer,and analyze the correlation between PTSD and QOL and study whether PTSD would influence QOL.Methods We investigated PTSD by using the PTSD-SS,and investigated QOL by using the EORTC QLQ-C30 V3,and the data was performed by SPSS 17.0.Results The PTSD-SS total score and the scores of EORTC QLQ-C30 of function field and of whole life quality field were negatively correlated,and the PTSD-SS total score and the scores in symptom field and six single measurement of EORTC QLQ-C30 were positively correlated.Conclusions PTSD of children and adolescents with cancer was closely related with the poor functional status and the high level of symptoms problem.PTSD has affected QOL.The higher level the PTSD is,the lower level of QOL will be.

Objective To explore the mechanism of immunologic injury in patients with Tourette's syndrome(TS). Methods The serum level of anti-brain antibody ( ABAb) , antinuclear antibody ( ANAb) , soluble IL-6 receptor (sIL-6R) and soluble gpl30(sgp130) in patients with TS were analyzed by commercially available ELISA kits,and the titer of anti-streptolysin O ( ASO) in TS and in control was examined with latex enhanced immunoturbidimetry. Results The level of sIL-6R and sgpl30 was significantly elevated in TS compared with control group [(44. 1 ± 15.8)ng/mL vs (30. 3 ± 9. 0) ng/mL and (69. 0 ±24. 6)ng/mL vs (47. 3 ±14. l)ng/mL,P <0. 01 respectively]. ASO titer(250 U/mL) was found higher in TS than that in control(P <0. 01). The positive rates of anti-brain an-tibody and antinuclear antibody in TS were higher than that in control group (66% vs 4% and 53% vs 25% , P <0. 01 respectively). The level of ABAb negatively correlated with sgpl30 concentration( r = 0. 375, P <0. 05 ). Conclusion IL-6 signal transduction might be involved in Tourette's syndrome to lead the function enhancementand start cascade of feedback inhibition, because of elevated levels of slL-6R, sgp130, ANAb and ABAb in serum.Autoimmune-related injuries may potentially explain the pathogenesis of the disease.

Objective To evaluate the value of DWI in assessing the biological characteristics of breast invasive ductal carcinoma (IDC).Methods Eighty-seven IDC lesions confirmed by postoperative pathology were involved in this retrospective study.The ADC values of IDC were compared among different lymph node status,grades,and molecular subtype.The correlations of ADC value and lymph node status,grades,and molecular subtype were evaluated.Results The ADC value of IDC with positive lymph node was lower than that with negative lymph node (P=0.035),and the ADC value of the high grade IDC was lower than those of medium grade IDC and low grade IDC (P=0.021,0.002).There was no significant difference of ADC value between different molecular subtypes.There was low negative correlation of ADC value with grades (r.s =-0.357,P 0.001) and week negative correlation of ADC value lymph node status and nolecular subtype (rs =-0.227,P=0.034;rs-0.093,P＜0.001).Conclusion DWI can provide useful information in evaluating the biological characteristics of IDC.

The judgment of early curative effect is important to the treatment of nasopharyngeal carcinoma and the prognosis of the patients.As a rapid imaging technique,magnetic resonance diffusion weighted imaging (DWI) is used to quantitatively analyze the changes of water molecules in the tissue by means of apparent diffusion coefficient (ADC),so as to diagnose the small lesions of nasopharyngeal carcinoma accurately,evaluate the early curative effect and observe the prognosis.With the continuous improvement and progress of MRI and data analysis technology,DWI in the diagnosis and treatment of nasopharyngeal carcinoma shows a broader application prospect.

OBJECTIVETo study the correlation between the MRI apparent diffusion coefficient (ADC) value and histological grade and molecular biology of breast invasive ductal carcinoma (IDC).

METHODSThis retrospective study included 125 patients with IDC verified by pathology from February 2010 to February 2013. Conventional MRI and diffusion-weighted imaging (DWI) examination were performed using a 3.0T scanner with diffusion factor of 0 and 800 s/mm(2). The region of interest (ROI) was drawn on the largest lesion and/or its two adjacent slices. The ADC value of the whole tumor was calculated as the mean ADC value. The correlation between mean ADCs and histological grade and biological factors was analyzed.

RESULTSThe mean ADC of pathological grade I, II and III IDC was (1.152 ± 0.072)×10(-3) mm(2)/s, (1.102 ± 0.101)×10(-3) mm(2)/s, and (1.035 ± 0.107)×10(-3) mm(2)/s, respectively. There was a statistically significant difference among them (P = 0.003). Statistically a significant difference was observed between grade III and I (P = 0.034), grade III and II (P = 0.006), but not between grade I and II (P = 0.741). A significant correlation was observed between ADC value and pathological grade (r = -0.342, P < 0.001). The median ADC values were significantly higher in the ER-negative than in the ER-positive cases [(1.130 ± 0.115)×10(-3) mm(2)/s vs. (1.060 ± 0.089) ×10(-3) mm(2)/s, P < 0.001)], in PR-negative than in PR-positive cases [(1.121 ± 0.106)×10(-3) mm(2)/s vs. (1.055 ± 0.096) ×10(-3) mm(2)/s, P < 0.001)], and in Ki-67-negative than in Ki-67-positive cases [(1.153 ± 0.090)×10(-3) mm(2)/s vs. (1.063 ± 0.101) ×10(-3) mm(2)/s, P < 0.001]. A statistically significant correlation was observed between ADC value and expressions of ER, PR, and Ki-67 (r = -0.311, r = -0.317, r = -0.414, P < 0.001).

CONCLUSIONADC value of breast invasive ductal carcinoma is correlated with histological grade, and expression of ER, PR and Ki-67.
