RESUMO
The basic mechanical properties of a Radial Shock Wave Therapy Equipment (RSWTE) were experimentally studied in this paper. The output energy of the RSWTE working on the operation frequency of 10 Hz was measured by dynamic pressure transducer under the conditions of different operation pressure. The results showed that both operation pressure and operation frequency have effects on the output energy of the equipment. The output energy increases with the increase of operation pressure, and the magnitude of increased energy decreases with higher operation of frequency. With the increase of operation frequency, the output energy rises up in condition of lower operation pressure and drops off in condition of higher operation pressure. The accurate medical treatment should be selected with the optimized energy and condition according to the treatment requirement to different illness in clinical medical applications.

Objective To investigate the reasons of upgrade pathologic diagnosis after cervical operation of LEEP and the principal of treatment.Methods 101 cases of clinical data with upgrade pathological diagnosis after LEEP in our hospital during september 2005 to May 2008 were analyzed retrospectively.Results 13 cases were diagnosed as cervical intraepithelial neoplasia(CIN)Ⅰ-Ⅲ while they were considered as chronic cervicitis pre-operation.60 cases of upgrade CIN and 10 cases of in-situ cervical cancer and 10 cases of early infiltration cervical cancer and 8 cases of infiltration cervical cancer were diagnosed while they were considers as CIN Ⅰ-Ⅲ before LEEP.Among the 101 cases.34 cases were re-treated.10 cases diagnosis were the same pathological diagnosis as before,14 cases diagnosis were downgrade and 10 cases were negative.There was no upgrade pathologic diagnosis.The cutting edges were negative.And lymphatic metastasis took place in 2 cases with infiltrating cervical cancer.Conclusion The malignant ratio of patients with upgrade pathology was high.We should pay attention to the patients with upgrade pathological diagnosis after LEEP.The possible treatment should be given to them according to their age,demands of breeding,chnieal stages and types of pathologic stages.
RESUMO
OBJECTIVE:To study the preparation and the quality control of the compound lomefloxacin nose-drops MET_HODS:The first order derivative spectrophotometry was used to determine the content of lomefloxacin with no need of isolation The detecting wavelengths were 293nm and 315nm RESULTS:The correlation coefficient was 0 9 999 The average recovery was 100 77%,with RSD of 0 82% CONCLUSION:The preparation process of compound lomefloxacin nose-drops was simple,the first order derivative spectrophotometry for the determination was rapid,simple and accurate
