AIM: To determine the mycoplasma infection and the drug resistance in outpatients with NGU. METHODS: Mycoplasma culture, identification and drug sensitivity assay were carried out with samples of 472 NGU patients by using one complex mycoplasma kit. RESULTS: 153 in 472 cases showed mycoplasma positive. The total positive rate was 32.4%. The positive cases of Uu, Mh and mixed both infection were 112( 23.7%), 11( 2.3%), and 30( 6.4%), respectively. The female positive rate was found significantly higher than that of male (? 2= 4.157,P

Objective To investigate the expression of platelet-derived growth factor B(PDGF-B) and PDGFR-α mRNA in the skin lesion of recurrent condyloma acuminatum(CA) and to explore its relationship with recurrent condyloma acuminatum.Methods The expressions of PDGF-B and PDGFR-α mRNA in the lesions of recurrent CA and Nonrecurrent CA were investigated by Real-Time-PCR,and the normal foreskins weretaken as controls.Results The PDGF-B and PDGFR-α mRNA levels in the re current CA group and non-recurrent CA group were significantly higher than those in the normal control group,the differences were statistically significant(P＜0.05).The expressions of PDGF-B and PDGFR-α mRNA in the recurrent CA group were higher than those in the non-recurrent CA group(P＜0.01).Furthermore,the expressions of PDGF-B and PDGFR-α mRNA before treatment in the recurrent CA group were higher than those after treatment(P＜0.01).Conclusion PDGF-B and PDGFR-α mRNA might haue a certain relation with CA recurrence.

Objective To analyze the clinical application value of cinematic rendering(CR)reconstruction technology in acute aortic dissection(AAD),and to compare the imaging quality between CR and volume rendering(VR)reconstruction.Methods Patients with suspected A AD who underwent aortic computed tomography angiography(CTA)were analyzed retrospectively.All images were uploaded to Siemens Syngo.via post-processing workstation for VR and CR three-dimensional reconstruction,respectively.The optimized view angle,staining and transparency were selected and segmented by a radiologist to display the lesion to the full extent.All subjective evaluations of post-processing images were randomly evaluated on Siemens Syngo.via post-processing workstation by two radiologists.The two radiologists reached a consensus after consultation,and the results without consensus were evaluated by another senior radiologist.The 3-point scale was used in the subjective evaluation of post-processing images.The scores of rupture,endometrium,and true and false cavity were recorded.The diagnostic confidence was also recorded.Results A total of 21 ADD patients were enrolled,11 patients(52.3％)were Debakey Ⅲ type.The scores of rupture in CR and VR reconstruction were 2.952 points and 2.619 points,respectively,which had significant difference(P=0.016).For the endometrium of AAD,the score of all 21 patients in the CR reconstruction was 3 points,while only 7 patients(33.3％)in the VR reconstruction had 3 points,which showed significant difference between the both(P＜0.001).For the true and false cavity of AAD,only 1 patient(4.8％)in the VR reconstruction was 3 points,while all 21 patients in the CR reconstruction had 3 points(P＜0.001).The scores of CR reconstruction on the diagnostic confidence were significantly higher than those of VR reconstruction(P＜0.001).Conclusion CR reconstruction can provide photorealistic anatomical post-processing images,and can improve the display and evaluation of AAD.
