People′s misunderstandings about the radiological check in health examination: Equalize the price of the medical check equipment with the accuracy of the check .The health examinees′misunderstanding about the harm which X-Ray can cause , thinking that low dose chest CT only can do very little harm to human body .The health examination unit makes the rate of finding out early lung tumor a main basis of assessing a medical personnel ′s achievement , which caused medical staff go against epidemiological laws when diagnosing tiny nodules .Misun-derstandings about some biological features such as the scale or the growing speed of the nidus , and laying exces-sive importance on the check accuracy , which caused some examinees received excessive X -Ray, overdiagnosis and overtreatment .So, people must treat radiological check in health examination rationally and dialectically , in order to further realize the legitimation and rationalization of radiological check .

A series of medical equipment question is introduced including currency use, combination, digital function and whole efficiency. By using system theory, the thought and viewpoint were put forward that how to solve equipment classification, "three turn" design (generalization, modularization, serialization), informationization alteration and affixation etc. Some thoughs on development strategy of medical equipment and creative information condition of field battle can be referred and provided.

Objective To explore diagnosis and operative treatment of primary cholecy stocarcinoma. Methods One hundred and thirty-six cases of biliary carcinoma were analysed for their clinical and pathological data and selection of the method of operation.Results The prognosis of late-staged cases was very bad.B-US and CT are still the most helpful means for clinical diagnosis.Conclusion The early diagnosis and treatment of primary cholecystocarcinoma are of utmost importance.

Objective To evaluate the significance of psychological intervention on elderly patients in urology department of primary hospital. Methods 60 patients in urology department of our hospital were selected from January to December, 2009, and were randomly divided into the observation group and control group with 30 patients in each group. The control group was given conventional treatment and care, the observation group received psychological interventions based on conventional care. Scores of self-rating anxiety scale(SAS), self-rating depression scale (SDS), the amount of Likert questionnaire score of the two groups underwent comparison. Results After treatment, anxiety and depression condition was much better in the observation group than the control group, the overall satisfaction rate in the observation group was 83.33%, much higher than the control group, 50.00%. Concluslons Psychological intervention is effective in treatment of the elderly patients in urology department,which should be applied in clinical practice.

Deregulated mTOR signaling pathway is associated closely with variety of human cancers. Preclinical and clinical studies of both classical and newly developed mTOR inhibitors in digestive system cancers show that these drugs not only have anti-tumor properties, but also can enhance tumor cells sensitivity to standard chemotherapy agents.

Enterovirus 71 (EV71) is one of the major pathogens that cause hand foot and mouth disease.Epidemics and pandemics have been periodically reported worldwide.EV71 also can cause serous complications and lead death in children.The mechanisms of EV71 cause serious complications has remained unclear,may relate to many factors,including cell tropism,cell death and host immune responses.This article reviews the recent advances in the identification of factors determining EV71 cell tropism,the associated mechanisms of viral infection-induced cell death and the interplay between EV71 and immunity.

Objective To compare advantages and disadvantages of ceramic crown and porcelain fused to metal(PFM),provide better rehabilitation ways for patients.Methods 258 porcelains were,divided into two groups:ceramic crown group 98 and metal ceramic crowns group 160,for preparation of abutment,modulus,colorimetric,feed production.Results Follow-up observation for 2 years,the 15 crowns of all appeared the gingival edge coloring with different degree,are PFM,10 patients were not satisfied with the color of restorations.8 repair body porcelain.Conclusion Inner crown metal of PFM is thin and light,with high hardness and compressive strength.It rarely occur deformation since repeated the barbecue at high temperatures,so suitable for large span bridge restoration.Ceramic crown because of no metal structure,good light transmission and light reflecting function,can reproduce the natural teeth translucent depth and color depth,strong sense of hierarchy,suitable for the repair of anterior teeth.

Objective To investigate the clinical significance of DHS and LCP in treating elderly patients with intertrochanteric fracture.Methods 58 elderly patients were randomly divided into 2 groups.30 of them( DHS group) were treated with DHS,while 28 cases of them were treated with LCP.Blood loss,operation time,bone healing time and Harris score were analyzed.After 1-year follow time,effective rate and complication rate were also recorded and evaluated in the 2 groups.Results The complication rate in LCP group was lower than that in DHS group(P ＜0.05),while the effective rate and Harris score in LCP were higher than that in DHS group( P ＜0.05 ).There were no significant differences in blood loss,operation time and bone healing time between the 2 groups ( P ＞ 0.05 ).Conclusion Compared with DHS,LCP is effective in treating elderly patients with intertrochanteric fracture.

Objective To explore the management status of long term care hospital nursing workers and find out appropriate countermeasures.Methods By using the methods of questionnaire survey and interview,management status of nursing workers from similar hospitals was investigated.The results were explored and applied combined with the nursing management of our hospital.Results Satisfaction degree of patients and their families about nursing workers increased from 76.7％ to 97.4％.Conclusions It is of key importance that continuous exploration and improvement of hospital nursing workers management be implemented to enhance the high quality nursing of elderly chronic disease hospital.

Objective To understand the distribution characteristics of HIV infection status among the outpatients in this hospi-tal to provide the beneficial supplement for local large-scale survey and the basis especially for the hospital infection control.Meth-ods The HIV screening situation on the outpatients of our hospital from 2007 to 2012 was retrospectively analyzed.Results Dur-ing these 6 years,108 999 specimens were detected,88 cases were positive in the preliminary screening and 81 cases were confirmed positive.The positive rate of anti-HIV antibody was 0.074%.In addition to voluntary counseling and testing,the specimens submit-ted by the outpatient anorectal department and the inpatient hematology department had the higher positive detection rate,which was 1.16% and 0.84% respectively.Conclusion The HIV infection rate in non-infectious disease specialized hospitals shows the increasing trend.The key departments must increase the intensity of the medical staff training,pay attention to early diagnosis of HIV/AIDS,prevent the hospital infection and reduce the risk occurred after the occupation exposure.
