OBJECTIVE:To provide reference and evidence for rational use of clinical nutrition. METHODS:The types of en-teral and parenteral nutrition and the cost of prescription were analyzed statistically in 17 third grade class A general hospitals,3 third grade class A special hospitals and 14 secondary general hospitals from Shanghai area during 2011 to 2013. RESULTS:Nutri-tion preparations were mainly used by hospitalized patients. Total cost of nutrition preparations in outpatient and emergency depart-ment respectively occupied 8.14%,8.77% and 8.89% of total cost of nutrition preparations in the hospital during 2011-2013. The parenteral nutrition was the main form of nutritional support. There were only three kinds of enteral nutrition in top ten nutrition preparations in the list of prescription cost. Although seven out of ten kinds of nutrition preparations were given enterally which was the main mode for outpatients and emergency patients,the cost of prescriptions of parenteral nutrition increased faster compared to enteral nutrition,especially alanyl-glutamine. CONCLUSIONS:Parenteral nutrition is the main mode of nutrition support,especial-ly for inpatients;great attention should be paid to the increase of the cost of prescriptions about parenteral nutrition in outpatients and emergency patients.

Objective:To investigate the relationship between college freshman adaptation and adverse childhood events,and to explore the mediating role of personality characteristics.Methods:A sample of 523 college freshmen from a key university in Sichuan Province was assessed with the China College Student Adjustment Scale (CCSAS),Adverse Childhood Events Questionnaire (ACEQ) and Eysenck Personality Questionnaire-Revised,Short Scale for Chinese(EPQ-RSC).Results:The rate of adverse childhood events of college freshmen was 87％ in current study.The total scores of adaptation were negatively correlated with the scores of adverse childhood events influence and neuroticism (r ＝-0.13,-0.51,Ps ＜ 0.01),while positively correlated with introversion-extroversion and lie (r ＝ 0.47,0.25,Ps ＜ 0.01).The scores of adverse childhood events influence were negatively correlated with scores of introversion-extroversion (r ＝-0.08,P ＜0.05) and lie (r ＝-0.12,P ＜0.01),while positively correlated with scores of neuroticism (r ＝ 0.17,P ＜ 0.01).Introversion-extroversion and neuroticism mediated the relationship between adverse childhood events influence and college freshman adaptation,the mediating effects were 51.65％ and 58.10％.Conclusion:College freshman adaptation may be closely associated with adverse childhood events influence and personality characteristics.Personality characteristics may play a mediating role between adverse childhood events influence and adaptation in college freshman.

Objective To study the clinical value of using a four-point method (FP) in measuring joint angles.Method Methods Twenty-five subjects without knee dysfunction were studied.Every knee joint was tested in extension,below 90° of flexion and above 90° of flexion with the traditional three-point method (TP) and the new four-point method.X-rays were taken as a gold standard measurement.The reliability and validity were analyzed using Bland-Altman plots,which can yield 95% limits of agreement (LOA).Results (1) The joint axis centers moved with changes in joint angle.(2) The 95% LOA of inter-tester reliability was (-5.0,2.7) with the FP and (-6.5,4.4) with the TP.The 95% LOAs of intra-tester reliability were (-3.6,4.0) for tester A and (-4.1,4.8) for tester B with the FP,while (-5.0,6.4) for tester A and (-6.1,5.8) for tester B with the TP.(3) The 95% LOAs in the three positions were (3.5,2.6) in extension,(-3.3,3.6) in mild flexion and (-1.9,5.7) in greater flexion with the FP,and ( 6.8,1.1),(-4.0,7.1) and (0,8.5) with the TP.Conclusions The FP gives better reliability and validity than the TP in joint angle measurement.

Objective To investigate the value of detecting HEART score and HEARTS3 score in risk stratification and prognosis of acute coronary syndrome (ACS) in patients with non-ST segment elevation chest pain in emergency department (ED).Methods Clinical data of case-control retrospective study of 775 patients with non-ST segment elevation chest pain in ED were collected from July 2011 to March 2015.The patients were estimated and risk stratification was made with HEART score and HEARTS3 score.After follow-up visiting by telephone for 30 days,outcomes were found to be ACS and myocardial infarction (MI).And the patients were categorized with score into low,intermediate and high risk groups.The correlation between the ACS and risk score in three groups was analyzed.Comparison of capability of performance in predicting 30-day ACS between the HEART score and HEARTS3 risk score.Statistical analyses were performed using SPSS13.0.Enumeration variables were expressed as percentage.For comparison of predictive value of the two sets of scores,area under the receiver operating curve (auROC) was calculated and compared by Z test.Results There were 92 cases with 30-day ACS.The rate of ACS had a trend of increase with increase in HEART score and HEARTS3 score.The patients with higher scores of HEART and HEARTS3,higher incidence of ACS in 30 days.Especially,the high-risk patients with score≥7 of HEART score and≥8 of HEARTS3 score had higher rate of ACS.And there was significant difference in predicting high-risk patients between two sets of scoring (P ＜ 0.05).The HEARTS3 score outperformed the HEART score as determined by comparison of areas under the ROC curve for MI (0.952 vs 0.813;P =0.028),30-day ACS (0.913 vs.0.815;P =0.034).Conclusions HEART score and HEARTS3 score both can be used to evaluate and perform risk stratification for non-ST segment elevation chest pain patients in ED.But HEARTS3 score can more precisely stratify high-risk patients with chest pain for 30-day ACS.

AIM To study the epidermal growth factor (EGF) and transforming growth factor ? (TGF ?)and the epidermal growth factor receptor(EGFR)during the course of rats gastric ulcer natural cure expressing and its possible biology meaning. METHODS We injected acetic acid to make the ulcer animal model, location expression characteristic of EGF and TGF ? and EGFR were studied by immunohistochemistry. RESULTS The normal rats stomach mucosa EGF,TGF ? and EGFR all expressed weakly at masculine. EGF and TGF ? was located at cytoplasm,and EGFR expressesed at cytoplasm and cell membrane and the expression position of the three ovrlopped with each other. EGF concentrated mainly on the cervical part of gastric gland, and TGF ? and EGFR, on the cervical and base parts of the gastric gland. Positive 9 expression cells were primarily parietal[FQ(11?46,X-WZ] and neck cells of the stamook muc. For materials taken during the course of ulcer natural recovery, regular ohanges were observed in TGF, TGF ? and EGFR expression. Higher expression was found in ulcer tissunes than in normal tissues, while the expression was not detectable in necrotic tissues and rarely detectable in granlation and scar tissnes. The expression became apparant only during healing and scar stages of ulcer but not in early stage. CONCLUSION ①TGF ?/EGFR autocrine system probably plays a leading role in maintaining rats mucosa completeness under the normal circumstances; ②EGF/EGFR and TGF ?/EGFR autocrine system may have important effect on the differentiation, hyperplasia, moving of cell and restraining the gastric acidity.

Objective: To explore the dietary patterns and related factors among urban middle school students in Guangzhou, and to provide the scientific reference for conducting nutritional education and intervention among the middle school students. Methods: Questionnaire survey was conducted for students in two grades (grade 1 of 27 junior and senior high schools) and their parents along with the physical examination for urban primary and secondary school students in Guangzhou. Dietary patterns were established by exploratory factor analysis. Multinomial Logistic regression model was used for analyzing influencing factors of dietary pattern. Results: Three major dietary patterns were identified. Type I (37.09%) was a healthy dietary pattern; type II (33.37%) and III (29.54%) were classified into western dietary patterns. Multinomial Logistic regression models showed that living on campus (ORⅡ=1.57, 95%CI:1.33-1.85; ORⅢ=1.28, 95%CI:1.07-1.52), screen time≥2 h/d (ORⅡ=2.89, 95%CI:2.51-3.33; ORⅢ=2.14, 95%CI:1.85-2.48) were positively associated with type II and III. The monthly household income per capita≥5 000 yuan (ORⅢ=1.31, 95%CI:1.14-1.51) was positively associated with type III. Senior students (ORⅡ=0.83, 95%CI:0.73-0.95; ORⅢ=0.74, 95%CI:0.64-0.85), the level of parental education (ORⅡ=0.64, 95%CI:0.52-0.79; ORⅡ=0.67, 95%CI:0.54-0.82; ORⅢ=0.72, 95%CI:0.58-0.90; ORⅢ=0.73, 95%CI:0.59-0.89) had a negative association with type II and III. Conclusion There are three dietary patterns among urban middle school students in Guangzhou. The main influencing factors include parental education, screen time, grade, resident situation, and monthly household income per capita.
