Objective To investigate the correlation between the expression of human leukocyte antigen B27(HLA-B27)antigen and ankylosing spondylitis(AS),and its implications for the diagnosis and differential diagnosis of AS.Methods Flow cytometry was used to detect HLA-B27.354 suspected AS patients,35 patients final diagnosed with AS and 30 patients diagnosed with rheu-matoid arthritis(RA)were enrolled in the study.Results The positive rate of HLA-B27 in 354 patients with suspected AS was 22.0%,in patients diagnosed with AS was 85.7%,which was higher than the RA group(P <0.05).In AS patients,Males accoun-ted for 77.1%,females accounted for 22.9%,and the patients′age mainly concentrated in youth.The sensitivity and specificity of HLA-B27 test was 85.7% and 100.0% respectively in the diagnosis of AS.Conclusion HLA-B27 antigen detection is important for early diagnosis and differential diagnosis of AS patients.

National Journal of Andrology 2015;21(11):1010-1013
OBJECTIVETo observe the clinical effect of Shugan Yiyang Capsules combined with sertraline in the treatment of premature ejaculation (PE).
METHODSWe randomly assigned 192 PE patients to receive sertraline hydrochloride 50 mg qd (control group, n = 96) or sertraline hydrochloride 50 mg qd plus Shugan Yiyang Capsules at the dose of 4 capsules tid ( combination therapy group, n = 96) , both for 6 weeks. We compared the intravaginal ejaculatory latency time (IELT) and Chinese Index of Premature Ejaculation ( CIPE) scores between the two groups of patients before and after medication and at 6 weeks after drug withdrawal.
RESULTSCompared with the baseline, the IELT was significantly increased after 6 weeks of medication in the combination therapy group ([1.41 ± 0.53] vs [6.69 ± 3.56] min, P < 0.05) and the control group ([1.43 ± 0.48] vs [5.37 ± 2.91] min, P < 0.05), and so was the CIPE score in the former (9. 80 ± 2.06 vs 21.62 ± 4.76, P < 0.05) and the latter group ([9.41 ± 1.97] vs [20.85 ± 4.83] , P < 0.05). In comparison with the pre-medication indexes, the IELT ([3.77 ± 1.63] min) and CIPE score (16.92 ± 3.37) of the combined therapy group were remarkably improved at 6 weeks after drug withdrawal (P < 0.05), but not those of the control ([1.19 ± 1.34] min and 10.59 ± 2.38, P > 0.05).
CONCLUSIONShugan Yiyang Capsules combined with sertraline have a definite and lasting effect on premature ejaculation.

7.Difference analysis of Orbscan Ⅱz corneal topography in anisometropic amblyopes:a contralateral eye study
Chinese Journal of Experimental Ophthalmology 2013;(6):582-586
Background The characteristics of anisometropic amblyopia in ocular morphology are becoming a hot topic in amblyopia field.And the interocular difference in corneal parameters of anisometropic amblyopia is to be understood here.Corneal topography is a non-invasive method for in vivo corneal examination and applied in our study.Objective This study was to investigate the interocular difference of corneal topography in anisometropic amblyopic patients Methods This was a serial cases observation.Thirty anisometropic amblyopes were selected in Center for Optometry and Visual Science,People's Hospital of Guangxi Zhuang Autonomous Region.The patients were divided into amblyopic eye group and fellow eye group based on the best corrected distance visual acuity.Corneal topography was examined with Orbscan Ⅱ z,and corneal morphological parameters such as Diff values of the anterior and posterior corneal surface,Sim K 's astigmatism,Kmax,angle kappa and central corneal thickness (CCT) were measured.The interocular differences in these parameters were evaluated by paired t test,and the correlations in these parameters between the amblyopic eyes and the fellow eyes were analyzed by Pearson linear correlation and simple regression analysis.Results The Diff values of the anterior corneal surface were (0.011±0.006)mm and (0.011±0.017)mm,and those in the posterior corneal surface were (0.031 ±0.012)mm and (0.026 ±0.008)mm in the amblyopic eye group and the fellow eye group,respectively.In addition,Sim K's astigmatism were (1.8± 1.1)D and (1.1 ±0.6) D,JCC were (77±80) °and (100±80) °,J0 values were (-0.17±0.72) D and (0.02±0.41) D,J45 values were (-0.16±0.79) D and (0.13 ±0.48) D,CCT values were (551 ±37) μm and (551 ±31) μm,angle kappa values were (6.4± 1.4) ° and (4.9 ± 1.2) ° in the amblyopic eye group and the fellow eye group,respectively.Significant differences were found in the Diff values of the anterior and posterior corneal surface,Sim K's astigmatism and angle kappa between the two groups (t=-3.041,P=0.005 ;t=-4.317,P=0.000 ;t=-4.571,P=0.000).Pearson's linear correlation test demonstrated significant interocular positive correlations in parameters such as the anterior corneal surface Diff values (r =0.444),J0 (r =0.383),posterior Diff values (r =0.600),and Sim K 's astigmatism (r =0.479),and CCT (r =0.948,P<0.05).The linear regression equation between the two groups was Y =-0.005 +1.392X (R2 =0.197,F=6.858,P=0.014) in the Diff values in the anterior corneal surface,Y =-0.013+0.421X (R2=0.360,F=15.761,P=0.000) in the Diff values in the posterior corneal surface,Y =0.616+0.27X (R2=0.230,F=8.348,P=0.007) in the Sim K's astigmatism,Y=0.060+0.219X (R2 =0.147,F=4.814,P=0.037) in theJo and Y=i08.289+0.804X (R2 =0.899,F=250.293,P=0.000) in CCT.Conclusions Corneal morphological interocular differences exist significantly in anisometropic amblyopic patients.

Objective To investigate the effect of different stimulating culture conditions and detecting methods on the frequency of Th17 cells and to set up and optimize the experimental method for detecting the frequencies of human Th 17 cells in peripheral blood by flow cytometry (FCM ) .Methods The peripheral blood in the healthy people was performed the stimulating culture by phorbol myristate acetate (PMA) at different final concentrations(50 ,100 ,150 ,200 ,250 ,300 ng/mL) and ionomycin 1 μg/mL .The frequencies of Th17 cells were assessed by FCM after different stimulating time points (4 ,6 ,8 ,10 ,12 h) .The mean fluorescence in-tensity(MFI) and percentage of the ratio of CD4 positive cells on the cellular surface and inside cell membrane were measured be-fore and after PMA stimulation .Results The frequency of Th17 cells was highest with the good stimulation effect under the condi-tion of PMA 150 ng/mL and ionomycin1μg/mL stimulation for 6 h (P<0 .05) .MFI of CD4 inside cellular membrane after stimula-tion was lower than that in the cells with stimulation after labeling membrane surface CD 4(P<0 .05) ,and the Th17 cell frequencies and the ratio of CD4 positive cells were higher than those in the latter ,but the differences were not statistically significant (P>0 .05) .Conclusion After stimulating whole blood with the final concentration of PMA 150ng/mL and ionomycin1μg/mL for 6 h , measuring intracytoplasm CD4 and IL-17 levels is the simple and effective method for detecting the frequency of human Th 17 cells .
