With the improvement of endoscopic technology,an increasing number of early esophageal cancer is diagnosed by gastroscopy.Regardless of the size or submucous fibrosis of esophageal cancer,endoscopic submucosal dissection (ESD) allows en bloc resection and histologically complete resection of the tumor.ESD has been recognized as an optimal treatment modality for early esophageal carcinoma.Currently,short-term curative effects of early esophageal cancer after ESD have been proved satisfactory,but the long-term outcomes remain unclear.This paper reviews the research advances about the long-term outcomes of ESD,and focuses on the postoperative stenosis,the recurrence,metastasis and survival rates of patients,to provide treatment reference for clinicians.

Objective To observe the clinical efficacy of electroacupuncture plus puncturing the thirteen ghost points in treating diabetic gastroparesis.Method Sixty patients with diabetic gastroparesis were randomized into a treatment group and a control group, 30 in each group. The treatment group was intervened by electroacupuncture plus puncturing the thirteen ghost points, while the control group was by electroacupuncture alone. The clinical efficacies were then compared.Result The total effective rate was 93.3% in the treatment group versus 83.3% in the control group, and the difference was statistically significant (P<0.05). Conclusion Electroacupuncture plus puncturing the thirteen ghost points is an effective approach in treating diabetic gastroparesis.

Objective To investigate the relationship of professional identity and social support among nursing undergraduates. Method Overall 286 nursing undergraduates participated in the survey by the professional identity scale and social support scale. Results The average score on the social support was (38.12 ± 4.70), and the average score on the professional identity of undergraduate nursing students was (107.29 ± 15.01), which was in the medium level. There was significant positive correlation between nursing undergraduates′social support and professional identity as well as other dimensions (P<0.05, P<0.01). Conclusions Nursing undergraduates′social support is closely related to its professional identity. It is suggested that the nursing undergraduates should be provided a variety of psychological and behavioral support and they should be helped to fully use social resources , so as to improve their professional identity.

Objective:To study the effects and mechanisms of Hongqi formular combined with exercise preconditioning against myocardial ischemic reperfusion injury in rats.Method:Fifty health male SD rats were randomly divided into sham,IR,EP,HP and EHP group.After establishing of EP animal model,the rats were ligated ramus descendens coronary artery to induce myocardial ischemic reperfusion model.The serum cardiac troponin Ⅰ (cTn Ⅰ),myocardium IL-6,TNF-α were detected by enzyme linked immunosorbent assay (ELISA).The myocardium MDA was detected by chemical colorimetry method.The myocardium SOD was detected by xanthine hydrocarbonylation.The serum ET,6-k-PGF1α,TXB2 density were detected by radioimmunoassay,and the myocardium Ca2+ density was detected by atom absorption spectrophotometry.Result:①As compared with the group IR,the serum cTn Ⅰ decreased significantly in groups EP,HP and EHP;As compared with the group EHP,the cTn Ⅰ level in serum was increased in groups EP and HP.②As compared with the group IR,the Ca2+ level in myocardial sarcoplasmic reticulum was decreased significantly in groups EP,HP and EHP;As compared with the group EHP,the Ca2+ level in myocardial sarcoplasmic reticulum was decreased significantly in group EP.③As compared with the group IR,the ET in serum were decreased significantly in groups EP,HP and EHP;As compared with the group EHP,the ET,TXB2 in serum were increased significantly in groups EP and the 6-k-PGF1αin serum were decreased significantly in groups EP.④As compared with the group IR,the IL-6 and TNF-α in cardiac muscle were decreased in groups EP,HP and EHP;As compared with the group EHP,the IL-6 and TNF-α in cardiac muscle were increased in groups EP and HP.⑤As compared with the group IR,the SOD in cardiac muscle was increased significantly in groups EP,HP and EHP and the MDA in cardiac muscle was decreased significantly in groups EP,HP and EHP;As compared with the group EHP,the SOD in cardiac muscle was decreased significantly in groups EP and the MDA in cardiac muscle was decreased significantly in group EP.Conclusion:Hongqi formular combined with exercise preconditioning produces cardio-protective effect during myocardial ischemic reperfusion,which may be related with the enhanced anti-oxidant ability,the decreased blood cell damage,the maintainace of vascular endothelium function,the improved microcirculation and the decreased calcium overloading.

Objective To improve the existing military water tank to prevent water pollution.Methods The modified water tank was composed of a lip,body,a floating ring filled with foam materials,a zipper,multi faucets,drain valve,rack and etc.The zipper on the top of the tank could close down the tank,the faucets at the lower part realized water supply,and the drain valve at the bottom discharged residual water.Results The dust,small animals and etc were prevented from going into the tank with the consumed water decreased,and the tank was easy to clean.Conclusion The tank contributes to military water supply at field conditions,and is worthy promoting practically.

Usage of the fruit and bark of a Melia-family plant as a digestive tract-parasiticide and agricultural insecticide was recorded about two thousant years ago in ancient China. Toosendanin (TSN), a triterpenoid, is an effectual ingredient extracted from the plant. Studies have demonstrated that TSN selectively affects neurotransmitter release, effectively antagonizes botulism, induces cell differentiation and apoptosis and inhibits proliferation of various human cancer cells, inhibits feeding and dovelopment in insects and modifies K+- and Ca2+-channel activity. The research data to demonstrate that TSN inhibits K+-channel and facilitates L-type Ca2+-channel are summarized, and the mechanism of action of TSN is discussed.

OBJECTIVE To enhance the control of nosocomial infection and the quality of medical nursing.METHODS The risk factors and etiological factors of nosocomial infection caused by non-medical-staff in sickroom were analyzed.RESULTS In order to control the nosocomial infection,we needed to strengthen the management in the following aspects: working procedures and tools of non-medical-staff,knowledge and sterilizing procedures for visitors,etc.CONCLUSIONS Standardized monitoring to non-medical-staff is the important measure to reduce the nosocomial infection.

War-fighter Physiologic Status Monitoring(WPSM)is a wireless sensor network that is used to collect,transmit,store and interpret physiologic data from soldiers,sailors and pilots.It can collect and monitor information regarding vital signs such as body temperature,heart rate,blood pressure,hydration and stress levels,sleep status,body position and workload capacity of the warrior.If necessary,the WPSM can notify medics and commanders if the soldier has been wounded or has become fatigued.The structure of the wireless sensor network in the WPSM and the data management of the sensor network are mainly discussed.

Objecive To explore modern management and optimization of hospital warehouse slotting with some class A tertiary hospital taken as an example.Methods EIQ_ABC classification method,multi-objective assignment model and genetic algorithm were used to analyze and simulate the data of 126 kinds of medical devices for 20 orders.Results The medical devices were divided into nine categories of Ⅰ A,Ⅰ B,Ⅰ C,Ⅱ] A,Ⅱ B,Ⅱ C,Ⅲ A,Ⅲ B and Ⅲ C.It's suggested that emphasized management and precision slotting storage were carried out for A categories of devices,dedicated storage for B categories and random storage for C categories.At the same time,the layout of the warehouse was optimized according to the importance of the goods so that the important goods were placed near the passageway.Slotting analog simulation diagram was obtained based on multi-objective assignment model of Ⅲ A category medical device.Conclusion Classified management and allocation as well as slotting optimization of medical devices contribute to improving hospital modern management in efficiency,cost and error rate.
