Objectives To study the correlation between social emotion and temperament in infants and toddlers. Me-thods The Brief Infant-Toddler Social and Emotional Assessment (BITSEA) and Toddler Temperament Questionnaire (TTQ) were used to evaluate the social emotional problems and temperament of 657 infants and toddlers 1 to 3 years old. Results The temperament dimensions were correlated with behavior and competence factors. The infants and toddlers in dififcult type group had more behavior problems or deifcits/delays in competence than those in easy type group (χ2=26.49, 10.48, P<0.01). Conclu-sions Infants and toddlers with negative temperament traits have more behavior problems and weaker social emotional compe-tences. The temperament should be considered in dealing with emotional problems.

Rectal cancer is a common malignant tumor in the gastrointestinal system.For the patients with resectable but high-risk rectal cancer,neoadjuvant and adjuvant chemoradiation plus surgery may improve local control.Compared to adjuvant chemoradiation,neoadjuvant chemoradiation showed the advantage of sphincter preservation.When the goal of preoperative chemoradiation was sphincter preservation,conventional radiotherapy was recommended.Through the analysis of the patients with 5-year survivals,the radiation had a similar impact on the survival as the chemotherapy alone for the patients with the intermediate risk factors.The impact on local control need to be further investigated before recommending chemotherapy alone for those subset patients.Advances in preoperative irradiation,postoperative irradiation and the comparison of preoperative irradiation with postoperative irradiation are also reviewed in this article.

AIM To research effects of sodium ferulate(SF) on transforming growth factor ?_1 inhibited hepatocyte growth. METHODS Human cultured hepatocytes(L02 cells) served as control group ,TGF?_1(5 ?g?L -1 ) was used to inhibited L02 cells to construct the cell model. MTT methods were used to study the growth inhibitory effect of TGF?_1 on L02 cells. DNA synthesis was analyzed by measuring 3H-TdR incorporation. The effects of SF on the changes of cell cycle were analyzed by flow cytometry. Generation of intracellular ROS was determined by the emission of fluorescence in L02 cells proloaded with DCFH-DA fluoresin and then treated them with TGF?_1 or SF. After 4h,control, TGF?_1 and TGF?_1+SF-treated cells were analyzed by flow cytometry. RESULTS ①Incubated in the presence of TGF?_1 for 24 h, 67.93% of L02 cells survived (P

Objective To determine the value of dynamic contrast enhanced (DCE?MRI) in predicting treatment response before preoperative chemoradiotherapy in locally advanced rectal cancer. Methods A cohort of consecutive patients with histologically confirmed rectal adenocarcinoma treated with preoperative chemoradiotherapy followed by total mesorectal excision (TME) surgery was enrolled in a prospective, pilot trial. All enrolled patients were examined using DCE?MRI at two time points: 2 to 5 days before neoadjuvant chemoradiation, 1 to 4 days before surgery. The following perfusion parameters (Ktrans, Kep, Ve) were measured for tumor. The patients were classified into pathological complete response (pCR) and non?pCR group according to the pathological results after operation. Those perfusion parameters were compared between the pCR and the non?pCR group and between before and after CRT in pCR and the non?pCR group with the t test. Receiver?operating curves (ROC) were constructed to further investigate the predictive value of Ktrans, Kep, Ve before neoadjuvant chemoradiation and were used to determine a threshold value at which patents with pCR could be distinguished from patients without complete response. Results The final study population consisted of 38 patients. There were 12 patients with a pCR and 26 patients with non?pCR. Before neoadjuvant chemoradiation, the mean tumor Ktrans, Kep and Ve for pCR group were (1.25 ± 0.56)/min, (2.10 ± 1.61)/min and 0.73 ± 0.34, respectively, for non?pCR group they were (0.46 ± 0.39)/min, (1.15 ± 0.77)/min and 0.32±0.12, respectively. All perfusion parameters showed significant difference between those two groups(t values were 3.45,5.67 and 6.23 respectively, all P<0.05). After neoadjuvant chemoradiation, the mean tumor Ktrans, Kep and Ve for pCR group were (0.28 ± 0.13)/min, (0.62 ± 0.27)/min and 0.21 ± 0.13 respectively, for non?pCR group, they were (0.32±0.12)/min, (0.83±0.42)/min and 0.17±0.10, respectively. All perfusion parameters showed no difference between those two groups(P>0.05), as well as the changes before and after neoadjuvant chemoradiation in those groups(P>0.05). ROC analysis for Ktrans pre?treatment revealed that Ktrans had an AUC of 0.837 in predicting pCR. A Ktrans of 0.66/min was emerged as the optimal cut?off for distinguishing pCR from non?pCR and for Ktrans>0.66/min, the sensitivity and specificity for predicting pCR were 75.0% (9/12) and 96.2% (25/26). Kep and Ve showed an AUC of 0.655 and 0.654 in predicting pCR. Conclusions In locally advanced rectal cancer, DCE?MRI can aid in predicting treatment response before preoperative chemoradiotherapy. Ktrans may become a better predictor to classify which patients will benefit from neoadjuvant chemoradiation.

Objective To explore the efficacy of high-resolution MRI in the prediction of tumor complete response after neoadjuvant chemoradiation therapy for T3 rectal cancer.Methods The clinical data of 108 patients with T3 rectal cancer who were admitted to Shanghai Cancer Center of Fudan University from 2010 to 2012 were retrospectively analyzed.The TNM stage of tumor,extramural depth of tumor invasion (mrT3 stage),involvement of mesorectum and rectal fascia,tumor diameter and distance from anal edge to lower edge of tumor were the main items of evaluation using the high-resolution MRI.A total of 108 patients underwent surgical resection of tumor after neoadjuvant chemoradiation therapy.The tumor complete response after neoadjuvant chemoradiation therapy was evaluated by tumor node metastasis (TNM) stage and tumor regression grade (TRG).The categorical data and multivariate analysis were done by the single factor analysis of variance (ANOVA) and Logistic regression analysis.Results The positive response rate of the T3a,T3b and T3c in the patients were 61.5％ (16/26),36.9％ (24/65) and 11.8％ (2/17) after neoadjuvant chemoradiation therapy,respectively.The mrT3,mrN and tumor diameter were the potential factors affecting response of neoadjuvant chemoradiation therapy by the univariate analysis of pathological restaging (x2 =50.474,30.985,8.318,P ＜ 0.05).The mrT3 was an independent risk factor affecting response of neoadjuvant chemoradiation therapy by the multivariate analysis of pathological restaging (OR =4.473,95 ％ confidence interval:2.003-9.991,P ＜ 0.05).There was no significant difference between the mrT3 stage,N stage,involvement of mesorectum and rectal fascia,tumor diameter and distance from anal edge to lower edge of tumor before therapy and the response after neoadjuvant chemoradiation therapy based on the tumor regression grade(TRG) (x2 =6.264,6.159,2.949,2.189,6.335,P ＞ 0.05).Conclusion The mrT3 in patients undergoing high-resolution MRI before neoadjuvant chemoradiation therapy could predict the tumor complete response after neoadjuvant chemoradiation therapy for T3 rectal cancer.

Development of liver fibrosis is closely associated with angiogenesis and abnormal vascular remodeling. Recent studies have highlighted the importance of angiogenesis and vascular remodeling in fibrogenesis, the results that inhibition of angiogenesis is effective in suppression of liver fibrosis demonstrate that therapies with several molecular targets against angiogenesis, inflammation and fibrosis might be beneficial for the treatment of cirrhosis. However, there is some evidence that inhibition of angiogenesis can even worsen fibrosis. This article outlines recent advances regarding the interplay between inflammation, angiogenesis and fibrogenesis in terms of cellular and molecular mechanisms, and suggests a requirement of greater understanding to intervene in these key processes, such as liver sinusoidal endothelial cell fenestration and impact distinct chemokine actions driving monocyte migration and differentiation, for therapeutic benefit in the future.
