OBJECTIVE To cultivate central supply unit member's custom of watching detail and dealing with everything carefully. To enhance central supply unit work's quality and efficiency,and decrease the phenomenon of article sterilized overdue and nipping tool's scathe. METHODS To organize study and enhance the cognition. To constitute regulations,systems and operation rule. To investigate the condition of medical instrument utilized,and pay attention to detail service for packaging sterilization. RESULTS The rate of overdue sterilized article decreased from 0.008% to 0.001%. The number of nipping tool's injuries decreased from 18 in 24 to 2 in 22 when the detail management was actualized. The rate of injury decreased from 75.0% to 9.09%. CONCLUSIONS In order to ensure the quality of asepsis of articles,we need to alter our conceptions,strengthen our responsibility,servicing more initiatively and carefulness.

OBJECTIVE To discuss the available methods of preventing the mattress pollution in the wards of the(hospital), and to keep the mattresses clean and dry and eliminate the hidden danger of nosocomial infection.(METHODS) The mattress protective covering is used of a new type of textile materials,and then applied into clinic.Selected 100 pieces of mattresses in the wards,divided them equally into two groups at random,the(experimental) group and the control group.After cleaning and pasteurization(surface) sampling and bacterial culturing for every mattress were undertaken.For the experimental group,spread the protective(covering) before the sheet,and for the control group,used the sheet directly.The colony number of each group was compared in the 3rd,7th,and 14th days.RESULTS The mattresses of experimental group were clean,light polluted and with less colonies,and that of the control group were heavy polluted and with more colonies.The comparisons of the total colony number and the number of every sampling point in the 3rd,7th,and 14th days of the two groups showed that there was a(significant) difference(P

Objective To make a summary of the clinical application and cooperation of piezosurgery in jaw bone tumour operation. Methods 64 patients with jaw bone tumour were selected since 2007 and were divided into the piezosurgery group and the routine group, they used piezosurgery and routine osteotome respectively. Feelings during operation, operation time, hemorrhage, postoperative reaction and complication were observed and compared. Results Discomfort and hemorrhage during operation was lighter, but operation was longer in the piezosurgery group compared with the routine group. Complications such as postoperative infection, hemorrhage and nerve damage did not occurred. Conclusions Application of piezosurgery in jaw bone tumor operation can increase comfort degree and reduce hemorrhage, it requires proficiency in operation procedures and master key aspects of nursing, so that can cooperate well.

Objective To improve the recognition and management of primary breast lymphoma(PBL) by discussing the clinical pathological characteristics and the prognosis of PBL. Methods The clinical and treatment records of PBL pa-tients admitted in Boai hospital of zhongshan from January 2001 to December 2012 were analyzed. Results All cases were B-cell origin(25/25),61.5%(16/25)were diffuse large B-cell lymphoma origin,The 5-year overall survival was 44%. There were no significant difference in the 5-year overall survival rates, 5-year local control rates and 5-year distant control rates in patient treatment with any surgery compared with no-Surgery(P>0.05).There were no significant difference in the 5-year overall survival rates and 5-year distant control rates in patient treatment with any RT com-pared with no-RT(P>0.05),but the 5-year local control rates was significantly different(P<0.05);There were no sig-nificant difference in the 5-year overall survival rates and 5-year local control rates in patient treatment with any chemotherapy compared with no-chemotherapy (P>0.05). but the 5-year distant control rates was significant different(P<0.05). Conclusion The prognosis of PBL is related with the clinical stage and pathological type. Radiotherapy and chemotherapy respectively promote the local control and distant control. The optimal treatment is surgery combined with chemotherapy and/or radiotherapy.
