Objective To investigate the effects of comprehensive pelvic floor rehabilitation program on pelvic floor muscle strength, female sexual function index (FSFI) score and sexual satisfaction scale for women (SSS-W) score in patients with perimenopausal female sexual dysfunction. Methods The clinical data of 120 patients with perimenopausal female sexual dysfunction were retrospectively analyzed, and all the patients were treated with estrogen and progesterone replacement therapy. Among the patients, 80 patients were treated with Kegel training program (control group), and 80 patients were treated with Kegel training program combined with comprehensive pelvic floor rehabilitation program (treatment group). The pelvic floor muscle strength, FSFI score, SSS-W score, incidence of algopareunia and sexual life frequency were compared between 2 groups. Results The pelvic floor muscle strength after treatment in treatment group was significantly better than that in control group. The Ⅲ,ⅣandⅤgrade of pelvic floor muscle strength in treatment group was in 5, 42 and 33 cases, and that in control group was in 21, 47 and 12 cases, and there was statistical difference (P<0.05). The FSFI scores and SSS-W scores after treatment in treatment group were significantly higher than those in control group:(32.24 ± 3.70) scores vs. (28.51 ± 2.95) scores and (139.80 ± 16.17) scores vs. (122.33 ± 13.75) scores, and there were statistical differences (P<0.05). The incidence of algopareunia after treatment in treatment group was significantly lower than that in control group:10.00%(8/80) vs. 55.00%(44/80), and there was statistical difference (P<0.05). The sexual life frequency after treatment in treatment group was significantly better than that in control group, the 0, 1, 2 and≥3 times/month of sexual life frequency in treatment group was in 0, 8, 20 and 52 cases, and that in control group was in 5, 34, 24 and 17 cases, and there was statistical difference (P<0.05). Conclusions Comprehensive pelvic floor rehabilitation program in patients with perimenopausal female sexual dysfunction can efficiently promote the recovery process of pelvic floor muscle strength, improve FSFI score and SSS-W score, and increase the degree of sexual satisfaction.

Objective To investigate the effect of tumor necrosis factor (TNF)-α antagonists on liver function and reactivation of hepatitis B virus ( HBV ) in patients with inflammatory arthropathy with concurrent chronic HBV infection.Methods Patients with active rheumatoid arthritis (RA) and ankylosing spondylitis (AS) who were grouped according to serum HBV biomarkers were treated with TNF-α antagonist.The liver function and reactivation of HBV were monitored before and after anti-TNF-α therapy.Kruskal-Wallis one-way analysis of variance on ranks of continuous variables and x2 test or Fisher's exact test for categorical variables among 3 or more groups.Results Fifty patients were enrolled with 3 to 23 months of follow-up visit.The level of transaminases in chronic HBV infection group [n=11,AST (36±18) U/L,ALT (44±46) U/L] were significantly higher than that in past HBV exposure group [n=16,AST (22±6) U/L,ALT (17±9) U/L] or free of HBV infection group [n=23,AST (19±6) U/L,ALT (15±9) U/L](AST:x2=11.161,P＜0.01,ALT:x2=8.038,P＜0.01).One patient with elevated baseline HBV-DNA load was treated concomitantly with lamivudine and anti-TNF-α therapy,and the HBV-DNA load reduced about to normal 4 months later.Among the other 10 patients with normal baseline HBV-DNA load in chronic HBV infection group,one patient showed reactivation of HBV with elevated transaminases after anti-TNF-α therapy; another patient had only elevated transaminases without reactivation of HBV,and the transaminases returned to normal after withdrawal of antiTNF-α therapy,which suggested drug-induced liver injury.All patients in both past HBV exposure group and free of HBV infection group remained HBsAg negative after the therapy.Conclusion Patients with inflammatory arthropathy should be screened for HBV infection and check liver function before anti-TNF-α therapy,and carefully monitor the reactivation of HBV and liver function during treatment.Patients with concurrent chronic HBV infection should be treated conco-mitantly with anti-virus and anti-TNF-α therapy if they have elevated baseline HBV-DNA load (＞105 copies/ml,in particular) and good economic situation.

Objective To investigate the dynamic expression and significance of B cell lymphoma (Bcl) 6 in fibroblast-like synoviocytes (FLS) induced osteoclast differentiation and activation in rheumatoid arthritis (RA) patients.Methods RA-FLS were co-cultured with peripheral blood monocytes (PBMCs) from healthy volunteers in the medium containing M-CSF.Bcl6 protein and mRNA in osteoclasts and their precursors were determined by immunofluorescence and Real-time PCR at day 0,7,14 and 21,respectively.Osteoclasts were identified by tartrate-resistant acid phosphatase (TRAP) staining.Bone resorption activity of osteoclasts was determined by bone slices stained with toluidine blue.Kruskal-Wallis H and Bonferroni were used for statistical analysis.Results ① Immunofluorescence staining and TRAP staining showed that Bcl6 protein was mainly expressed in the nuclei of PBMCs.After co-cultured with RA-FLS for 7 days,some PBMCs differentiated into macrophages and a few differentiated to TRAP-positive multinucleated osteoclasts,and the total Bcl6 protein expression in osteoclasts and their precursors were increased.At day 14,the total Bcl6 protein expression was increased further.At day 21,the Bcl6 protein expression in nuclei of osteoclasts was decreased while PBMCs were differentiated into osteoclasts,and total Bcl6 protein expression was decreased.②Real-time PCR showed that Bcl6 mRNA expression in osteoclasts and their precursors at day 7 tended to increase than that at day 0 (x2=3.429,P＞0.05).At day 14 after co-cultured with RA-FLS,Bcl6 mRNA expression in osteoclasts and their precursors was significantly higher than that at day 0 (x2=5.333,P=0.045).At day 21,the expression of Bcl6 mRNA was significantly lower than that at day 14 (x2=6.023,P=0.038).Conclusion Bcl6 may be involved in osteoclast differentiation and activation,and may play a role in the inflammatory status in the process of differentiation from PBMCs to macrophages.Further studies are needed to establish the mechanisms.

Objective To study effect of lower genital tract infection on premature rupture of membranes and maternal and child outcomes. Methods Selected 413 cases with lower genital tract infection on premature rupture of membranes and maternal and child outcomes were divided into term subgroup and preterm subgroup. Selected 420 cases without premature rupture of membranes as control group. Cervical secretions were collected to detect Chlamydia and My-coplasma, and vaginal secretions were collected to detect candida yeast, bacteria and trichomoniasis. Membranes were collected for pathological examination. Effect of lower genital tract infection on premature rupture of membranes and maternal and child outcomes was analyzed. Results Mycoplasma infection, chlamydia infection, bacterial vaginosis,candida, trichomonas infection rates of premature rupture of membranes group were higher than control group(P<0.01 or P<0.05). In group of premature rupture of membranes, Mycoplasma infection, chlamydia infection, bacterial vagi-nosis, candida, trichomonas infection rates of preterm subgroup were higher than term subgroup(P<0.01 or P<0.05). Premature birth, puerperal infection, chorioamnionitis, neonatal pneumonia incidence of cases with lower genital tract infection were higher(P<0.01);premature birth, puerperal infection, chorioamnionitis, neonatal pneumonia incidence of premature rupture of membranes group were higher(P<0.01). Conclusion Lower genital tract infection increases the chance of premature rupture of membranes,and is an important factor leading to maternal and infant adverse outcomes.
