OBJECTIVE To compare the detection rates of Ureaplasma urealyticum(Uu),by 4 kinds rits and find out the best one.METHODS Using four kinds of mycoplasma detection kits,namely are French mycoplasmaIST2,Zhuhai Livzon′s ICS,Dark horse′s IES and Shanghai Its Prachanda,under the same conditions,the mycoplasma of the Clinical specimens for 260 cases were tested.RESULTS The detection rate of mycoplasma(Uu) for 48 hours by four kinds of brands kits about mycoplasma liquid culture was as follows 45.4% for French MycoplasmaIST2,36.2% for Zhuhai Livzon′s ICS,37.7% for Dark horse′s IES and 36.8% for Shanghai Its prachanda.The results of susceptibility test: the reagent of IST2 had.the lowest resistance to josamycin,doxycycline,clarithromycin,ofloxacin and azithromycin,and had the better results than the other three kinds of reagents.Mycoplasma reagents form different companies had significant differences in resistance rates to five kinds of antibiotics.CONCLUSIONS The results suggest that when we cultivate clinical mycoplasma should be careful to select of the mycoplasma liquid culture identification kit.

Objective Our objective was to design a new type of bedpan (inflatable, bed urinal) and compare its effect with common bedpan. Methods We divided 144 patients with bone fracture and lying in bed into the test group and the control group with 72 cases in each group from May 2006 to February 2007. Inflatable bed urinals were used in the test group and common bedpans were used in the control group. The pain alleviation, comfort degree, staining of bed sheet and skin injury were observed and evaluated in each group. Results Application of inflatable bed urinal was superior to common bedpan in the following aspects: alleviation of pain, comfort degree, staining of bed sheets and skin injury. Conclusions Adoption of inflatable bed urinal could alleviate pain, prevent the incidence of complication and reduce the workload of nurses.
