Objective To investigate the effect of bilateral sacrospinous ligament fixation by Pavlik harness method in the treatment of pelvic organ prolapse (POP). Methods Sixty patients with POP received operation were divided into bilateral sacrospinous ligament fixation by Pavlik harness method group (study group,30 cases),posterior intravaginal sling plasty group (P-IVS group, 15 cases) and sacrospinous ligament fixation group (SSLF group, 15 cases) by random digits table. The data of the three groups, such as operation time, bleeding during the operation, indwelling urinary catheter time, duration out of bed after operation, cure rate, recurrence rate and the quality of sexual life were observed. Results The operation time in study group [( 30.5 ± 5.3 ) min] was significantly shorter than that in SSLF group [(43.5 ± 10.6) min](P ＜ 0.05 ), and the duration out of bed in study group [( 1.5 ± 0.6) d] was earlier than that in SSLF group [(3.1 ±0.7) d] and P-IVS group [(3.3 ±0.8) d](P＜0.05). The POP-Q stage of all the patients being hospital was 0 or Ⅰ , approached the cure standard. Patients were followed up for 3-16 months after operation, the recurrence rate and the decrease of the quality of sexual life in study group [0,3.3%(1/30)]were lower than those in P-IVS group [20.0%(3/15),13.3%(2/15)] and SSLF group[6.7%(1/15),26.7%(4/15)] (P ＜ 0.05). Conclusion Bilateral sacrospinous ligament fixation by Pavlik harness method is a simple, firm operation, and the position of vagina does not axialitily change and suits the anatomy, so it is effective and worth spreading clinically to treat the POP.

Objective To compare PCR-SBT to IMS-ELISA in the HLA-B27 detection in the ankylosing spondylitis (AS)pa-tients.Methods Simultaneously,PCR-SBT and IMS-ELISA were used to detect the HLA-B27 expression in peripheral blood samples which were suspected patients with AS from 120 cases.Chisquare test of paired design and the area under curve of receiver operating characteristics of SPSS17.0 software were used to evaluate the value of PCR-SBT and IMS-ELISA in HLA-B27 detection of AS patients.Results Among 120 cases of suspected patients with AS,the positive rates of HLA-B27 detected by PCR-SBT and IMS-ELISA were 45.83%(55/120)and 37.50% (45/120),respectively.There was statistical difference between the two methods in the HLA-B27 detection (χ2 =59.455,P =0.000).The sensibility and spe-cificity of PCR-SBT were 96.36% and 96.92%,respectively.While the sensibility and the specificity of IMS-ELISA were 69.09% and 89.23%,respectively.Area under the curve of two methods were 0.966 and 0.792,respectively.Conclusion In comparison with IMS-ELISA,the sensibility and the specificity of PCR-SBT in HLA-B27 detection were higher in AS diag-nosis,that is to say,PCR-SBT is better in HLA-B27 detection and AS diagnosis.
