Objective To evaluate the value of PET-CT in patients with breast cancer and to determine if the PET-CT can provide additional information to predict early response to neoadjuvant chemotherapy (NAC).Methods NAC was given to 20 patients with breast cancer confirmed by biopsy puncture from September 2009 to March 2012.The PET-CT was carried out for all patients before NAC.TEC program with three weeks for one cycle was selected.After 6 days of the first cycle,the PET-CT was performed again.The changes of standard uptake value before and after the first cycle were compared.At the same time hand palpation was selected to detect the changes in tumor size before and after the first cycle of NAC.The changes of the standard uptake value and in tumor size need to refer to the pathology Miller & Payne classification methods to evaluate the efficacy of the NAC.Results The SUV were (7.51±1.76) Bq/ml and (4.98±1.61) Bq/ml before and after chemotherapy (t =7.916,P ＜ 0.05) the maximum tumor diameters were (9.62±4.38) cm and (8.89±4.08) cm before and after NAC (t =2.154,P＞ 0.05).SUV had highly correlated with pathological MP classification (r =0.725,P =0.000); while for the tumor size there was no significant change (r =0.026,P =0.824).Conclusion PET-CT can predict the efficacy earlier and is more accurate than clinical efficacy standard for the NAC.

Objective:To compare the applicability and consistency of NRS2002,SGA and MNA in general surgery hospitalized patients and analyze the effect in clinical outcomes of NRS resuits with respect to each tool.Method:The 150 patients hospitalized in our hospital were chosen as object of study,to screen and evaluate nutritional risk of patients by NRS 2002,SGA and MNA,respectively,on the second hospital day,then to compare the consistency of NRS results with respect to the four tools on clinical outcomes.Results:The applicabilities of hospital NRS2002,SGA and MNA were alternatively 97.25,97.25％ and 98.35％.The evaluation of patients' NRS corresponding to different four tools was consistent.The effects of screening results of MNA,NRS2002 and SGA on clinical outcomes were most closely related.Conclusion:The three nutritional evaluation tools can be applied to the screening of malnutrition in General Surgery.The effects of screening results of NRS2002 and SGA on clinical outcomes were most closely related.

Objective: To explore the socioeconomic status and psychological characteristics of the children with oppositional defiant disorder(ODD), and to provide evidence for revealing the pathogenesis of ODD. Methods: General Conditions Questionnaire and Achenbach Children′s Behavior Checklist Scale (CBCL) were used to evaluate 44 cases of ODD children aged 8 to 14 years old who were first referred to the Eighth People′s Hospital of Zhengzhou City from August 2016 to January 2017, and 50 healthy children were randomly selected according to their grades from a primary school in Zhengzhou.Chi-square test and independent sample t test were used to analyze data. Results: The father′s and mother′s education levels and family per capita income in ODD group were lower than those in healthy control group, and their academic achievements in ODD group were worse than those in healthy control group, and the diffe-rences were statistically significant(all P=0.000). The scores of schizoid (2.32±2.73), depression(4.48±6.12), social problems(3.09±3.34), compulsion(4.05±5.60), social withdrawal(2.39±3.20), hyperactivity(4.95±4.37), aggressive behavior(7.59±7.62) and rule-breaking(2.91±3.85) in ODD children were higher than those of the healthy control group(1.04±1.37, 1.48±2.06, 0.68±1.13, 0.78±1.46, 0.60±1.16, 1.70±1.98, 2.48±3.28, 0.62±1.58), and the differences were statistically significant(all P<0.05). The scores of social problems(2.85±3.33), compulsion(3.96±5.11), social withdrawal(2.63±3.16), hyperactivity(5.44±4.50) in male ODD children were higher than those in the male healthy children(0.80±1.05, 1.30±1.92, 0.95±1.50, 2.15±1.56), and the differences were statistically significant(all P<0.05). Compared with the female children(0.83±1.22, 1.10±1.84, 0.60±1.18, 0.43±0.92, 0.53±1.09, 0.37±0.80, 1.40±2.17, 1.87±2.14, 0.30±0.78), the scores of schizoid(2.24±2.64), depression(4.65±4.93), social problems(3.47±3.37), compulsion(4.18±6.38), somatic complaints(2.12±3.65), social withdrawal (2.00±3.26), hyperactivity(4.18±4.12), aggressive behavior (8.24±7.26) and rule-breaking(3.76±4.85) in female ODD children were significantly higher, and the differences were statistically significant(all P<0.05). There was no significant gender difference in the score of CBCL scale in ODD group(all P>0.05). Conclusions There are significant emotional and behavioral problems in ODD children whose family socioeconomic status is lower, and their psychological characteristics vary with gender differences.
