Objective To compare the efficiency of National Early Warning Score (NEWS),Chronic Respiratory Early Warning Score(CREWS) and BAP-65(elevated Blood urea nitrogen,Altered mental status,Pulse＞109bpm,age＞65 years)among patients with AECOPD (acute exacerbations of chronic obstructive pulmonary disease).Methods Totally 181 patients with AECOPD were investigated by these three scales,and the efficiency of NEWS,CREWS and BAP-65 was compared.Results The scores of NEWS,CREWS and BAP-65 in the death group were higher than those in the survival group and the general ward group(P＜0.01).Regarding the predicted results of hospital death,the area under the ROC curve of NEWS,CREWS and BAP-65 was 0.878,0.836 and 0.774,respectively,and the differences were not statistically significant(P＞0.05);for predicted results of ICU admission,the area under the ROC curve of NEWS,CREWS and BAP-65 was 0.826,0.813 and 0.716,respectively,and the differences were not statistically significant (P＞0.05).Conclusion NEWS,CREWS and BAP-65 have satisfied predictive efficiency for prognosis,and NEWS and CREWS are much easier and faster to use.

Objective To evaluate the efficacy and side effects of extensive regional field radiotherapy concurrent with chemotherapy for locally advanced esophageal cancer.Methods Of the 101 patients with locally advanced esophageal cancer patients,44 patients were treated by involved field radiotherapy alone,29 patients treated by involved field radiotherapy combined with chemotherapy,and 28 patients received extensive regional field radiotherapy combined with chemotherapy,the total dose of radiotherapy was 60 Gy.The clinical target volume (CTV) of involved field included the gross tumor volume (GTV) plus a 0.8 cm lateral margin,the tumor plus a nominal 3-5 cm cephalad and caudal margin.Extensive regional field radiotherapy was delivered in two steps:the CTV included the CTV of the involved field plus elective nodal region in the first step;in the second step,the CTV definition was same with the CTV of the involved field.Synchronous chemotherapy regimens included TP and NP.Results 90.1％patients completed planned radiotherapy,all patients in the concurrent chemotherapy groups completed at least one cycle of chemotherapy.The follow-up rate was 99％.Twenty-four and 42 patients completed followed-up more than 24 months in the radiotherapy alone and concurrent chemoradiotherapy group,respectively.The median survival time of the involved field radiotherapy group,involved field chemoradiotherapy group and extensive regional field chemoradiotherapy group was 13,21 and 19 months,respectively;the 2-year overall survival (OS) rate was 15％,48％ and 46％,respectively for the three groups.The 2-year OS rate was improved significantly in the chemoradiotherapy group (x2 =6.83,P =0.033).Compared with radiotherapy alone group,the incidence of grade three or four bone marrow suppression was higher in the concurrent chemoradiotherapy group (53％: 0 ％,x2 =32.94,P =0.000),the remaining adverse events (acute radiation pneumonitis,acute radiation esophagitis,esophageal fibrosis,late radiation lung injury) had no significant intergroup differences (x2 =5.56,6.70,2.39,0.42,P =0.235,0.349,0.881,0.981).Conclusions Compared with radiotherapy alone,concurrent chemoradiotherapy can improve the survival rate for locally advanced esophageal cancer.The side effects of the extensive regional field radiotherapy combined with chemotherapy is well tolerated.But the efficacy of the extensive regional field radiotherapy combined with chemotherapy needs further research.

Objective In view of the trend of networking development in modern high education and the characteristics of students' strong self-learning ability, Peking Union Medical College established a multimedia morphological teaching website from 2013 including human anatomy, neuroanatomy, histology and embryology.Methods According to the teaching demand, the use of the ASP script, combined with Mysql database completed the website development, from the interface design to the curriculum, the syllabus, presentations and laboratory videos uploading.Results Through the questionnaire survey, 45% of the students use website more than 3 times a week, and course content column has the highest use frequency (79%).An independent learning platform effect has been achieved.Conclusions After nearly 4 years exploration and practice, multimedia website has become an important part of morphological courses, as a kind of new teaching mode, not only popular for college teachers and students, but also widely used in clinical teaching.

OBJECTIVE: To explore the relation between diabetes mellitus and clinicopathological factors and the incidence of radiation pneumonitis in patients with non-small cell lung cancer. METHODS: The data of 332 patients with non-small cell lung cancer, who were admitted to the Department of Oncology of Third Xiangya Hospital of Central South University between January 2007 and August 2009, were collected retrospectively. The patients were divided into a diabetes mellitus (DM) group (n=45) and a non-diabetes mellitus (NDM) group (n=287). The clinicopathological factors were compared between the two groups. The patients who received radiotherapy were further divided into a diabetes mellitus (DMR) group (n=33) and a non-diabetes mellitus group (NDMR) group(n=287), and the incidence of radiation pneumonitis was compared. RESULTS: A total of 45 patients (13.55%)developed diabetes mellitus. There was significant difference in the body-weight, age and hypertension (P<0.05), while no significant difference in the pathologic factors, such as tumor pathological type, degree of differentiation, and classification of malignant tumors (TNM) stage between the two groups(P>0.05). No significant difference in the irradiation area was found between the DM group and the NDM group(P>0.05). The incidence of radiation pneumonitis in the DMR group was 42.42%(14 out of 33), while 21.31%(39 out of 183) in the NDMR group, with significant difference in the incidence of radiation pneumonitis between the DMR group and the NDMR group(P<0.05). The risk value in the DMR group was 2.721 folds (95%CI, 1.253-5.910) that in the NDMR group in patients with non-small cell lung cancer companied with diabetes mellitus. CONCLUSION Diabetes mellitus is the risk factor of radiation pneumonitis for patients with nonsmall cell lung cancer who receive radiotherapy.
