RESUMEN
Objective To investigate the infection of HPV subtypes in male urethra in Xi'an area.Methods The eighteen subtypes of HPV DNA were detected in 478 cases of male patients by PCR-reverse dot hybridization assay (RDB) including low risk subtypes (HPV6,11,43) and high risk subtypes (HPV16,18,31,33) during 2015～2016.Results The total infection rate of HPV subtypes in 478 subjects was 44.97％ (215/478).The percents of subjects infected by one subtype,two ones,three ones,four ones and five ones were 32.85％ (157/478),8.79％ (42/478),2.09％ (10/478),0.42％ (2/478) and 0.84％ (4/478),respectively.The detection rates of low risk subtypes and high risk ones were 40.17％ and 22.38％ in which the most common subtypes were HPV6 (24.69％),HPV11 (12.13％),HPV16 (5.65％),HPV43 (3.35％) and HPV52 (2.30％) and those of others were from 0％ to 2.09％.The infection pattern of HPV subtypes gave priority to one subtype infection in all age groups.There was statistically different between H PVs (6,11,16,43,52,66) in twenty years or older subjects (x2 =12.879～109.7,P=0.000～0.025).Conclusion The majority of HPV subtypes detected in male urethra were HPV6,HPV11,HPV16,HPV43 and HPV52 in Xi'an area which provided epidemiological data for HPV infection in males.
RESUMEN
Objective:To compare the detective effect between color Doppler twinkling artifact and B-mode ultrasonography for kidney stones in order to develop an ultrasonic model that can more easily and more accurately detect kidney stone.Methods: 9 patients with kidney stone who were confirmed by CT scan in recently were selected to accepted two methods (color Doppler twinkling artifact and B-mode ultrasonography) to detect kidney stone. The video fragments of upper pole, interpolar and lower pole were created by three radiologists and the results were diagnosed by them.Results: In dual kidneys of the nine patients, 32 stones with average size of (8.9±7.5) mm were found. The sensitivity, specificity, positive predictive value and negative predictive value of the B-mode ultrasonography were 71%, 48%, 52% and 68%, respectively, while those of color Doppler twinkling artifact were 56%, 74%, 62% and 68%, respectively.Conclusions: In the detection of kidney stones, B-mode ultrasonography is more sensitive when is used alone, but color Doppler twinkling artifact has more high specificity. The color Doppler twinkling artifact should be applied in more clinical practices, and a new commercial ultrasonography mode that used basic acoustic difference and is special for detection of kidney stone should be researched and developed so as to improve the detection of kidney stone.
RESUMEN
In this article, medical consumable materials supply catalog technology was introduced through the principle, method and application of topic studies, at the same time bar code tags to tag and identify medical consumable materials were introduced. These two techniques established the correspondence between the real supplies logistics and information flow system, provided foundation for medical supplies all process tracking and traceability management. Supply catalog and encoding identification technology provide a new solution for the effective management of medical consumable materials.
