Prevalence and Factors Associated with Female Sexual Dysfunction in Beijing, China.

BACKGROUND: Female sexual dysfunction (FSD) is a highly prevalent and often underestimated problem. However, large-scale, population-based epidemiological surveys of FSD are scarce in China. The present study was conducted to evaluate the prevalence and the potential risk factors of FSD across a selection of social groups in Beijing, China, based on the Female Sexual Function Index (FSFI). METHODS: A cross-sectional study based on the multiple-stage cluster sampling was performed with adult women throughout the Dongcheng and Shunyi districts of Beijing. The Chinese version of FSFI was used, as well as questions on demographic characteristics, the disease-related context, and social relationships. RESULTS: A total of 6000 consecutive women entered this study, with an actual response from 5024 women, corresponding to a response rate of 83.7%. A total of 4697 (78.3%) questionnaires were effective. The prevalence of adult FSD in Beijing was 2973 (63.3%) using a score of 26.55 as the boundary value, whereas the total mean FSFI score was 23.92 ± 6.37. However, 1423 (30.3%) women did not seek help. By multivariate logistic regression analysis, the possible potential risk factors included age (odds ratio [OR] = 1.051), dissatisfaction with the spouse's sexual ability (OR = 3.520), poor marital affection (OR = 2.087), spouse sexual difficulties (OR = 1.720), dissatisfaction with married life (OR = 1.476), living in a rural area (OR = 1.292), chronic pelvic pain (OR = 1.261), chronic disease (OR = 1.534), previous pelvic surgery (OR = 1.605), vaginal delivery (OR = 2.285), lower education (OR = 3.449) and postmenopausal (OR = 3.183). CONCLUSIONS: As suggested by the FSFI scores, female sexual problems are highly prevalent in Beijing. Dissatisfaction with the spouse's sexual ability, poor marital affection, sexual difficulties of the spouse, dissatisfaction with the marriage, rural life, CPP, and postmenopausal were conceivable risk factors for FSD in Beijing women.

[Prospective study on total pelvic reconstruction surgery with Prosima in the treatment of pelvic organ prolapse stage III].

OBJECTIVE: To evaluate the safety and efficacy of total pelvic reconstruction surgery with Prosima in treatment of pelvic organ prolapse (POP) stage III. METHODS: From July 2010 to December 2011, 31 patients with POP stage III undergoing total pelvic reconstruction surgery with Prosima were enrolled in this prospective study. Among two cases complicated with stress urinary incontinence underwent transobturator tension-free vaginal tape concomitantly with total pelvic reconstruction surgery with Prosima. Clinical parameters during peri-operation were recorded and compared. Pelvic organ prolapse quantitative examination (POP-Q) and anatomic improvement in these patients after surgery were analyzed. Comparisons of pelvic floor impact questionnaire-short form 7 (PFIQ-7) and pelvic organ prolapse-urinary incontinence sexual questionnaire-short form 12 (PISQ-12) in these patients before and after surgery were used to evaluate quality of life and quality of sexual life. RESULTS: The mean operating time was (55 ± 13) minutes, mean blood loss was (66 ± 25) ml. No severe intraoperative complications were observed. All patients were able to recover spontaneous micturation within 5 days. Two cases experienced pelvic hematoma with diameters less than 7 cm, and resolved later. Another case was urinary tract infection. At the median follow-up 6 months (1 - 15 months), the rate of anatomic success defined as the leading vaginal edge above the hymen was 94% (29/31). There were significant improvements in Aa, Ba, Ap, Bp, and C (P < 0.01) by POP-Q. Two patients showed recurrent prolapse at 3 months and 1 year after surgery, without the need of further operation. The median score of post-operative PFIQ-7 was 0 point at 6 months and 0 point at 12 months after operation, respectively, which were significantly lower than that of 50 points pre-operation (P < 0.01). And there was no significant difference in the average score of PISQ-12 before and after surgery [(30 ± 6) points versus (31 ± 4) points] (P > 0.05). The rate of mesh exposure was 16% (5/31), all the 5 cases occurred within 6 months and was cut in clinic. There was no case of de novo urinary incontinence and de novo dyspareunia. CONCLUSIONS: Pelvic reconstruction surgery with Prosima is safe and efficacy in treatment of POP stage III. It could improve quality of life remarkably without influence on sexual quality of life.

[miR-34s--a tumor suppression protein p53 highly related microRNA].

Several microRNAs, most representing the miR-34, are highly related to tumor suppression protein p53. p53 exerts its tumor suppression function known as inhibiting multiple-oncogenes, such as Bcl-2, c-myc and cell cytokines such as cyclinE2, cyclinD1 and c-Met through the regulation of miR-34. On the other hand, miR-34 enhances the activities of p53 by inhibiting silence information regulator I (SIRTI). The positive feedback regulatory network based on p53 and miR-34 families play an important role in suppression of oncogenesis and deterioration. This paper summarizes the latest advances of p53 highly related miR-34 families in oncogenesis and treatment.
