Objective: To explore the preventive and therapeutic effects of Compound Zhuye Shigao Granule (CZSG), a compound Chinese herbal medicine, on radiation-induced esophagitis in rats. Methods: Fifty-six Wistar rats were randomly divided into 5 groups: normal control group (8 rats), model group (12 rats), and high-, medium- and low-dose CZSG groups (12 rats in each group). The rats in the normal control and model groups were given normal saline 10 mL/kg body weight and those in the CZSG-treated groups were given solution of CZSG at doses of 1.15, 2.30, or 4.60 g/kg body weight respectively by intragastric administration once a day for 7 days. Then esophagitis was induced by local irradiation of (60)Co ray (490.25 cGy/min, totaled 30 Gy). The administration was continued for another 7 days or 14 days, meanwhile body weight and daily food intake of the rats were recorded. Seven days after the irradiation, 4 rats in each group were sacrificed under anesthesia, then, the esophageal tissue was obtained for histopathological examination and the degrees of esophageal tissue injury and neutrophil infiltration were scored. Fourteen days after the irradiation, all the survival rats were dealt in the same way. Results: (1) Seven days after the irradiation, the esophageal tissue sections in the model group showed typical histopathological changes of radiation-induced esophagitis, whereas in the CZSG groups the histopathological changes were lessened dose-dependently and in the high-dose CZSG group the esophageal tissue remained basically intact. (2) The scores of esophageal tissue injury and cellular infiltration in the high- and medium-dose CZSG groups were both significantly less than in the model group (P<0.05). (3) The body weight of the rats increased in the normal control group, whereas it decreased obviously in the model group. In the medium- and high-dose CZSG groups, it did not decrease significantly. The decrease of body weight in the high-dose CZSG group was less than that in the model group (P<0.05). (4) Compared with the normal control group, the daily food intake was reduced in the other groups. However, it was significantly greater in the low, medium- and high-dose CZSG groups than in the model group (P<0.05). Conclusion: In rats with radiation-induced esophagitis, CZSG can effectively relieve the esophageal tissue injury and cellular infiltration, increase daily food intake, and prevent rats from lose of body weight dose-dependently, which show that CZSG has the preventive and therapeutic effects for radiation-induced esophagitis in rats.

OBJECTIVE To investigate the present situation of the nosocomial infection in our hospital in order to decrease the infection rate. METHODS A total of 40 554 patients were inspected from Oct 2004 to Sept 2005.There were 626 patients with nosocomial infection. RESULTS The nosocomial infection was 1.54%.Old patients were the main components.The longer they were in hosptial,the more risk of infection they had.Elder monitoring department and hematological department were the most common infected units.Respiratory tract was the most common infected site of the body.The entity of disease for the most infection was malignant tumor.Invasive treatment was one of the causes for the infection. CONCLUSIONS The infection rate of our hospital was relatively low.We should establish the system to control the infection.Use the advanced statistical software well be to aid the control and discover the anti-infection deficiency from the statistical view-point.

OBJECTIVE Based on data analysis of nosocomial infections in our hospital,main reasons of the infection,especially the relationship between infection risk and malignant conditions were investigated in detail. METHODS A retrospective study of 50 272 patients in the period form Jan 2000 to Dec 2007 showed 2979 patients(5.93%) had nosocomial infections.The reasons caused nosocomial infections were diverced. RESULTS The patients with severe blood disorder or tumors were at high risk of nosocomial infections.The longer the stay in hospital,the higher the risk they had.Moreover,the Department of Hematopoietic Stem Transplantation and the Department of Hematological Disease both accounted for the majority of nosocomial infections.Intervention therapy was another main reason of the infection.Respiratory tract was the most common infection site. CONCLUSIONS The infection rate of our hospital is lower among same kinds of hospitals.To reduce infection risk further,a new system with advanced statistical analysis software is being established.The system includes a monitor motif which could conquer the current weakness.

With the application of HIS in hospital,a great deal of data accumulate in database.It's very important to take advantage of these data for IT and managerial staffs.It is suggested that data mart be selected to process the data at the initial stage.

AIM: To study effects and adverse drug reactions of mtrisone in the treatment of patients with severe acute respiratory syndrome. METHODS: The information of the medications in 680 patients with severe acute respiratory syndrome (SARS) in Xiaotangshan Hospital was collected by HIS system and the effects and ADRs of metrisone were staiated. RESULTS: The kinds of drugs of SARS patients who had been cured by metrisone were more than those which were not cured by metrisone. Condition of SARS patients who had been cured by metrisone was more serious than those which were not cured by metrisone. The ADRs rate, blood glucose and leukocyte of SARS patients who had been cured by metrisone are higher than those which were not cured by metrisone while blood K+ is lower. CONCLUSION: The utilization of metrison to SRAS patient should be more cautious to balance the effects and ADRs of metrisone.

In order to deal with the defects of data quality during the process of hospital information system operation,this paper puts forward the quality supervision and control system to supervise the data quality in real time and in the end.The system uses server data quality supervision model based on standard store.The advantage of this model is to discover data quickly and give early-warning to users without affecting the data input at terminals.

Objective To calculate workload according to working day and holiday separately.Methods Functions of SQL in Oracle were used to separate working day and holiday.Results The method could accomplish holiday's workload statistics expediently.Conclusions Statistics of holiday's workload are becoming ordinary work,so the separated analysis for them has practical value.

Objective To explore the daily management mode of hygienic materials of locomotive logistics unit. Methods Through the method of building deposit area and buffer area in regular depot, hygienic materials with validity regulation such as drugs could be included in hospital regular inventory manage ment; the hygienic materials were dynamically replaced according to the hospital's daily cost. Results Under the condition of ensuring the adequateness of hygienic materials, the method was able to meet the validity requirement and avoid wasting as well. Conclusion Hospitals have favorable condition and professional management in reserving different types of hygienic materials. As it costs time to assemble materials, this management mode is more suitable for the management of hygienic materials of locomotive logistics unit.
