Objective:To determine the distribution of T-lymphocyte subpopulations in peripheral blood and its relationship with disease-free survival (DFS) of patients with different molecular subtypes of invasive breast cancer (IBC). Methods:Data and plasma samples of 372 female patients with IBC treated at Tianjin Medical University Cancer Hospital and Institute between January 2008 and August 2009 were obtained. CD4+/CD8+ratio and the amount of regulatory T cells (Treg cells) and natural killer cells (NK cells) were measured through flow cytometry. Results:A total of 133 (35.8%), 124 (33.3%), 48 (12.9%), and 67 cases (18.0%) presented luminal type A, luminal type B, HER-2 over-expression, and triple-negative type breast cancer (TNBC), respectively. In TNBC, a longer DFS was observed when the peripheral CD4+/CD8+ratio was high or when the level of Treg cells was low (CD4+/CD8+P<0.05 and Treg P<0.05). However, CD4+/CD8+and Treg are not independent prognostic factors for the DFS of TNBC cases. In other molecular subtypes of breast cancer, CD4+/CD8+ratio and the amount of Treg cells are not correlated with DFS (P>0.05). The level of NK cells is unrelated to the DFS of breast cancer with the four molecular subtypes (P>0.05). Conclusion:CD4+/CD8+ratio and the amount of Treg cells in peripheral blood may predict DFS of TNBC but are not considered as independent prognostic factors.

Objective To observe bone marrow MR imaging of adult acute leukemia patients in first diagnosis and to reveal the rule of bone marrow infiltration and the role of MRI in diagnosing and predicting the prognosis of untreated acute leukemia adult patients. Methods Fifty-four adult acute leukemia patients received MRI after diagnosis relying on FAB subtype and immunophenotyping including 28 cases with AML and 26 cases with ALL. MR imaging was obtained by the short time inversion recovery and T 1W spin echo technique of pelvis and femur at one time. The examining results of morphology and blood routine were collected at the same time. 15 age-matched volunteers were selected as controls. Results MRI showed that bone marrow of all patients were infiltrated by leukemia cells. The MRI appearance was classified into five patterns based on scope of focus. MRI patters from grade 1 to grade 3 were observed in most of patients with AML and in none with ALL, however, all patients with ALL distributed in grade 4 to grade 5. The distribution of patterns had significant difference between AML and ALL (P

Objective To evaluate the efficacy and safety of endoscopic mucosal resection (EMR) for rectal carcinoid tumors. Methods From January 2006 to January 2009, EMR was performed in 28 patients with rectal carcinoids, who were followed up to evaluate the therapeutic effect and safety. Results Tumor diameters varied from 0.4 cm to 1. 2 cm (mean 0.7± 0. 2 cm). Negative resection margin was a-chieved in 26 cases (92. 9% ), tumor margin within 0. 1 cm of resection margin in 1 (7. 1% ) , and two margins coincided in 1 patient (7. 1% ). Hemostasis was performed with metal clips in 14 patients (50% ) and argon plasma coagulation (APC) in 9 (32. 1% ). Except for rectal bleeding in 1 patient (3. 6% ) , no other complications were observed. There was no recurrence in any patients during a follow-up of 6-36 months. Conclusion EMR is a useful and safe method for treatment of small rectal carcinoid tumor which does not cross submucosal layer.

Objective To explore the effect of schisanhenol on adipokine expression in 3T3-L1 adipocyte and its related mechanism. Methods 3T3-L1 adipocyte was cultured in vitro and induced to differentiation and maturity. Glucokinase was added to culture medium to make an oxidative model. The expression of adipocytokines were detected under the circumstance of different doses and at different time points of schisanhenol. Results The expression of adiponectin, leptin, resistin and visfatin were decreased with the increase of glucokinase concentration. Concentration-dependent inhibition effect was most obvious in leptin (25 mU/ml Glucokinase vs Blank group, t =7.29, P<0.01). With pretreatment of oxidative stress, the adipocytokines increased as the doses of schisanhenol increased (t=6.31,P<0.01 in adiponectin;t=5.92, P<0.01 in leptin; t=3.77, P<0.05 in resistin; t=3.63,P<0.05 in visfatin). With the extension of schisanhenol effect, the expression of four adipokines showed the process of first decrease-then increase'. The effects of schisanhenol on adipokines were parallel with the alteration of oxidative stress. Conclusions Schisanhenol increased adipocytokines expression in 3T3-L1 adipocyte by reducing oxidative stress, and the increase of leptin and adiponectin were most obvious, which indicated that schisanhenol could play a role in the treatment of diabetes by Chinese herb wuweizi.

Objective:To revise the Chinese version of Devereux Early Childhood Assessment for Preschool-ers,Second Edition (DECA-P2 ),and assess its validity and reliability.Methods:Totally 608 children aged 3 -5 years were rated by their teachers with the Chinese version of DECA-P2 and two criterion scales,which included the Chinese version of Preschool Behavioral and Emotional Rating Scale,and Social Competence and Behavior Evalua-tion Scale-30.Data of 570 were valid.After identifying valid items using item analysis,exploratory factor analysis was performed for half of all samples.Confirmatory factor analysis was also conducted with another half samples.Moreover,the present study tested criterion-related validity,internal consistency reliability and split-half re-liability of the Chinese version of DECA-P2.Results:Through the exploratory factor analysis,the obtained structure of protective factors was the same as the original scale,accounting for 59.82%of the variance.The results of con-firmatory factor analysis achieved the standard of psychometrics (χ2/df=2.50,RMESA=0.07,CFI=0.91,IFI=0.91).Generally,each subscale had significant correlation with the two criterion scales (r=-0.21 ~0.80). Be-sides,the Cronbach αcoefficients of all subscales were between 0.80 and 0.93,and the split-half reliabilities of them were between 0.79 and 0.89.Conclusion:The Chinese version of DECA-P2 has acceptable psychometric quality and can be applied to evaluate resilience for children aged from 3 to 5 years in China.
