OBJECTIVE To study the possibility of air sterilization with solution of camphor leaves. METHODS Every six adjacent sickrooms that had same volume from 9 different clinical sectors were randomly selected for testing.Air of all sickrooms were sterilized by atomizing with solution of camphor leaves that was rough made by boiling and filtering and by direct irradiating with ultraviolet ray respectively.And then screened the sterilization effect of two methods respectively by air culture. RESULTS After sterilization with 100% solution of camphor leaves,all sickrooms were in line with standard of class Ⅲ(500 CFU/m~3),and 70% sickrooms were in line with class Ⅱ(200CFU/m~3).Both atomizing with solution of camphor leaves and direct irradiating with ultraviolet ray showed obvious effect,the result of air culture indicated that CFU of microorganisms were significant differrent between pre-sterilization and post-sterilization in both methods(P0.25). CONCLUSIONS Camphor leaves are very effective for sterilization and deserve to spread.

Objective:To optimize the macroporous resin separation process for total flavonoids in papaya. Methods:The content of total flavonoids in papaya was selected as the index, and the resin model, sample solution concentration, ratio of diameter and height, the flow rate of adsorption, type and volume of eluent, type and volume of impurity removing solvent, elution velocity and the other parameters were investigated. Results:The optimal purification process was as follows: the macroporous resin type was D-140, the sample solution concentration was 0. 1 g·ml-1 , the sample volume was 2BV, the ratio of diameter and height was 1∶9, washing the impurities with 3BV water, eluting with 3BV 10% ethanol first followed by 3BV 50% ethanol with 2BV·h-1 , and collecting 50%ethanol elution. The total flavonoids content was 52%. Conclusion:The optimized process can separate and purify the total flavonoids in papaya effectively.

Background and purpose:Inadequate surgical operation of gastric cancer may cause introgenic tumor cell dissemination and peritoneal seeding.This study introduced a new technique of the interrupted procedure to prevent gastric cancer cells dissemination in the radical resection of gastric cancer.Methods:Patients received gastric interrupted procedure employing the use of gastric interrupted forceps in the carcinoma of antrum,gastric body or cardia.The interrupted effect,complicated nature of the procedure and the preliminary result of CK19 mRNA expression in the portal blood by RT-PCR techniques of the interrupted group and the routine operation group were analyzed.Results:All the patients were successfully interrupted in the gastric operation,but there were some differences in the detailed procedure between the carcinoma of antrum,gastric body and cardia.Special attention should be given to the prevention of spleen scrape via the interrupted forceps,and to the posterior gastric trauma in case there is adhesion between the stomach and pancreas.Nine patients (9/17) of the routine operation group have positive portal blood CK19 mRNA expression whereas all 17 patients have negative portal blood CK19 mRNA expression in the interrupted group.Conclusion:The interrupted procedure is an easy,useful and safe method of manipulating and to preventing a large amount of gastric cancer cells from disseminating in the portal blood during the radical operation of gastric cancer.
