Neuroendocrine neoplasm (NEN)is a group of heterogeneous tumors originated from the peptidergic neurons and neuroendocrine cells. A revised system of classification, nomenclature and grading of NEN was proposed by the fourth edition of“World Health Organization classification of tumours of the digestive system”in 2010. It apparently contributes to unify the method of classification, put an end of the confusion in nomenclature, standardize the grading system and predict the outcomes more accurately. With the combination of the results by immunohistochemical studies, pathologists should be in accordance with the requirements to make a diagnosis of NEN with accurate classification, grading and the pathological parameters essential to staging. Recently, new advances in NEN study put forward a new view in the classification and grading system that will lead to the updates of the diagnostic system after further studies on a large scale of samples.

Objective To explore the effects of combined sevoflurane and remifentanil on shoulder dislocation in elderly patients.Methods A total of 100 elderly patients with shoulder dislocation were randomly divided into the control group and the observation group (n =50,each group).The control group was anaesthetized with remifentanil and the observation group was anaesthetized with sevoflurane and remifentanil.The clinical efficacy of anaesthesia,life quality and the University of California at Los Angeles (UCLA) shoulder rating scale were recorded.Results The excellent rate of anaesthesia was higher in observation group than in control group (92.0％ vs.68.0％,x2 =9.033,P=0.011).There were significant differences in mean arterial pressure (MAP),heart rate (HR) and arterial pulse oxygen saturation (SpO2) between the control and the observation group after anaesthesia [(86.3±3.0) mm Hg vs.(83.1±2.5) mm Hg,(83.2±4.5) times/min vs.(81.1±4.0) times/min,(94.4±5.5)％ vs.(92.0±6.0)％,respectively,t=5.794,2.466,2.085,all P＜0.05].There were significant differences in the onset time of anesthesia,surgery time,recovery time,and hospital stay days between the control and the observation group [(26.6± 6.6)min vs.(5.1±1.3) min,(4.6±2.1) min vs.(2.3±1.2) min,(4.9±2.3) min vs.(2.8±1.1)min,(205.5±121.1) minvs.(121.3±89.3) min,respectively,t=22.600,6.724,5.824,3.957,all P＜0.01].The scores of life quality and UCLA function were significantly higher in observation group than in control group after anesthesia (t =16.873,8.485,both P =0.000).Conclusions The treatment of combined sevoflurane and remifentanil treatment has a good clinical efficacy in elderly patients with shoulder dislocation.It can improve the scores of UCLA and life quality of elderly patients with shoulder dislocation.

[Conclusion] In the aspect of treating the refractory asthma, Chang Qing has got rich clinical experience and effective. methods to relieve the asthma,his clinical dialectic thinking and the originality of prescription are greatly worth learning.

The clinical data was collected from 26 orthodontics patients at our hospital .All of them received straight wire appliance .The observed teeth were randomly classified into experiment and comparison groups.After the mounting of orthodontic bracket , Duraphat was smeared on the surface of maxillary central incisor, maxillary lateral incisor, maxillary canine, maxillary first premolar and maxillary first premolar in the experiment group while no Duraphat was applied in the comparison group .After wearing orthodontic appliance for 1, 3, 6 and 9 months, enamel demineralization of each tooth was observed .And the enamel decalcification index ( EDI ) of different areas of each tooth at different timepoints was recorded .More demineralization areas existed in the comparison group than the experiment group (P<0.01).In addition, no Ⅲ degree enamel demineralization was observed in the experiment group after Duraphat applying for 1 month.EDI were 0.20, 0.24, 0.21 and 0.16 in the experiment group after Duraphat applying for 1, 3, 6 and 9 months versus 0.37, 0.44, 0.44 and 0.34 in the comparison group during the same time periods.Therefore EDI and demineralization areas were significantly smaller in the experiment group than those in the comparison group (P<0.01).

A new body surface projection method and a method of mapping with the H-C lead, based on the wave array transmission hypothesis of electrocardial solid field, are proposed. The results of mapping with the H-C lead in 31 cases of established chronic myocardial infarction were compared with those made synchronously with Wilson's lead and other limb leads.The present study demonstrated that mapping with the H-C lead had following three advantages: (1) the patterns of the left ventricular infarction were consistent with those of the Wilson's lead mapping; (2) the right border of the infarction outline was quite clear; (3) the configuration of the surface projection of the upper wall and diaphragmatic wall of both ventricular infarction, and the anterior, lateral and posterior wall of right ventricular infarction could be satisfactorily defined. Re-cults of the mapping with H-C lead in 31 cases also showed pseudo-infarction 12.9%, infarction involving right ventricle 35.5%, involving diaphragmatic wall 41.9%, and involving upper wall 45.2%. There were twenty two different patterns of surface mapping in 27 cases in this series.

Currently, some students place more emphasis on the pursuit of their individual values, but less on their social responsibilities. This can be attributed to the students themselves and the society as well. In order to develop their sense of social responsibilities, the article suggests that we should maintain proper guidance on their values,convert our concept of intellectual fostering and direct college students to participate in social practice.
