Objective The diagnosis and treatment of modern hospital are greatly influenced by medical devices. With the widespread introduction of medical equipment, the scientific management how to carry on the instrument and appliance by the administrative department of hospital becomes an unavoidable problem. Methods Based on the definition of medical equipment, basic attributes and management skills, some key questions which the administrator should notice and solve in the scientific management are introduced, and gives out the principle and method. Results It is pointed out that scientific management can correctly guide the investment of equipment, and gain great benefit with a minimum input. Conclusion Investment according to the developmental strategy is proposed, which provides strong theoretical basis for leadership and administrative departments.

Objective To discuss the procurement managerial technique standard for medical equipment importation.Methods The procurement managerial technique standard for medical equipment importation was studied from the aspects of flows for international bidding,declaration and operation as well as related specifications.Results The imported medical equipment according with the procurement managerial technique standard,gifted with a high cost performance,satisfied the requirements of the nation and the hospital.Conclusion The managerial technique standard can promote the procurement of imported medical equipment.

Objective To identify the factors that may influence the risk of relapse.Methods 122 patients were included in the study,and 12 clinicopathologic factors related to the relapse of ulcerative colitis were analyzed by univariate and multivariate Cox regression proportional hazards mode.Results Multivariate analysis showed the exatrointestinal manifestations,Induced factors,irregular therapy and the compliance of patients were independent prognostic factors for the relapse of ulcerative colitis.Conclusion The patients with UC should be treated regularly and avoid inducing factors.When patients have exatrointestinal manifestations,they should be monitored closely to prevent relapse.

During medical activity,there are theory and realism spring of that the right of emergency treatment is in conflict with the right of informed consent.Simply investigating responsibilities is of no avail to solve the conflicts.To Interpret the real reasons of the conflict through legal and ethical aspects.To avoid and reduce conflict,the effective measures are that perfecting the rules of relevant law,elucidating the rights and obligations of hospital and medical staff;regulating the contents of informed consent form and strengthening medical ethics education.

Objective To observe the efficacy of Shuilongjian in treating cerebellar infarction, and compare with the pure western medicine. Methods 67 inpatients with cerebellar infarction enrolled were divided into two groups according to the method of random digits table, 36 cases in the treatment group and 31 cases in the control group. The control group was given 500 mL dextran by venoclysis, once a day. The treatment group was given Shuilongjian as an additional drug. The therapeutic effect was evaluated according to the nerve function and the total capability in dealing with daily activities. Result All the 67 cases of cerebellar infarction were included in the analysis. The effective rate of the treatment group was better than that of control group with 83.3% and 58.1% (P

Objective To analyze the death situation of workers in Anshan iron and steel group corporation, find the main death causes of them and provide scientific evidence for developing strategies for disease control and prevention and health education. Methods The data, came from the annual registration of dead workers of the Group, death registrations of insurance company and death database of Anshan city from 2001 to 2003, were collected and classified with ICD-9. Results Workers over 50 years old accounted for 37.42%, and retired workers over 60 years old nearly 50 000 people. The top five death caused were cerebral-vascular disease (CVD), malignant tumor, coronary heart disease (CHD), chronic obstructive pulmonary disease (COPD), injury and poisoning. The mortality rate were 174.91 / 105, 110.56 / 105, 83.28 / 105, 33.27 / 105, and 29.30 / 105, respectively. The sequence of death cause in male workers was in accordance with that in overall population, and the first and second death cause in female workers was malignant tumor and CVD, others were in accordance with those in overall population. Conclusion Chronic diseases are the main diseases impacting the health and life of the workers.

Objective To investigate the association between the gastroesophageal reflux and functional bowel disorder.Methods 168 patients with epigastric symptomswere involved in the survey.A validate questionnaire on gastroesophageal reflux symptoms was performed by the physician.There were 68 patients in the Sc≥12 group and 100 patients in the Sc

We produced α-ketoglutaric acid (α-KG) from L-glutamic acid, using enzymatic transformation approach with L-glutamate oxidase (LGOX). First, wild strain Streptomyces sp. FMME066 was mutated with NTG, a genetically stable mutant Streptomyces sp. FMME067 was obtained. Under the optimal nutrition conditions with fructose 10 g/L, peptone 7.5 g/L, KH2PO4 1 g/L and CaCl2 0.05 g/L, the maximum LGOX activity reached 0.14 U/mL. The LGOX was stable to pH and temperature, and Mn2+ had a stimulating effect. Finally, after 24 h enzymatic conversion under the optimal conditions, the maximum titer of α-KG reached 38.1 g/L from 47 g/L L-glutamic acid. Enzymatic transformation by LGOX is a potential approach for α-KG production.

ObjectiveIn order to understand changes of immunological response under different psychic state. MethodsMice were divided into two groups,male and female group, 1: 2, were feeded together for together group, anther was that mice, male, were feeded solely for thesolely group. Male mice in two groups were immunized with sheep red blood cell(SRBC). Titer of antiboty against SRBC and IL -2 in serum wasdetected. Results The titer of antibody against SRBC in together group was higher than that in solely group. The concentration of IL - 2 was lowerin the solely group comparing with the together group. ConclusionIt was suggested that psyxhological status had impact on immune system.
