Sexual function in patients presenting to a urogynecology practice

The purpose of this study was to evaluate sexual function in women referred to a urogynecology practice. All new patients were mailed an optional female sexual function index (FSFI) in conjunction with their history forms; other sexual function information was obtained during the physician interview. Over 6 months, four hundred fifty new patients were enrolled. Of these, 243 (54%) were not sexually active. Reasons listed for sexual inactivity included partner problems/no partner (32%), low desire (14%), prolapse (10%), and pain (10%). There were several differences between sexually active and non-sexually active participants; however, after a multivariate analysis, only age, marital status, and stage/grade 1–2 of prolapse remained significant. One hundred nine sexually active patients completed the FSFI; the majority was sexually active two to four times per month. Female sexual dysfunction was noted in 70 (64%) patients. Lowest scores were noted for the domain of desire, followed by arousal, orgasm, lubrication, satisfaction, and pain. Reduced frequency of intercourse was the only factor significantly associated with dysfunction. Ninety-four percent were not embarrassed by the survey. Overall, sexual inactivity is common in patients presenting for urogynecologic care. Those that are sexually active report low rates of sexual activity and high rates of sexual dysfunction. Most sexually active patients will accept a sexual function questionnaire as part of their routine assessment.This research was presented at the American College of Obstetricians and Gynecologists annual clinical meeting, May 10, 2005, San Francisco, CA, USA.     

IIEF-5与NEVA检测在阴茎勃起功能障碍诊断中的意义

目的探讨应用国际勃起功能评分5(IIEF-5)问卷表结合夜间阴茎勃起测定系统(NEVA)筛选勃起功能障碍(ED)的可行性及意义。方法148例门诊ED病人,应用IIEF-5问卷表评分,再通过NEVA测定仪监测夜间阴茎勃起情况,次日数据输入主机回放并分析。结果93例为心理性ED;在19~69岁的5个年龄组中,重度ED的比例由11.8%到55.0%,NEVA中度异常者IIEF积分(12.98±2.58)分,NEVA重度异常者IIEF积分(7.32±1.04)分。结论NEVA能有效地鉴别心理性与器质性ED,IIEF-5评分值与NEVA检测阴茎勃起时血容量变化值有相关性。IIEF-5与NEVA检测结合,能提高诊断和评估ED的可靠性。     

衰老对大鼠阴茎组织NO-cGMP通路及端粒酶活性的影响研究

目的探讨衰老对大鼠阴茎组织结构、NO(nitric oxide)-cGMP(cvclic Guanosine Monophosphate)通路及端粒酶活性的影响作用。方法本课题以不同月龄大鼠阴茎组织及培养的平滑肌细胞为研究对象,检测不同月龄大鼠阴茎组织中NO量、NOS(Nitric Oxide Synthase)活性、cGMP量、端粒酶活性及海绵体结构的变化,并比较大鼠、人阴茎组织及大鼠原代海绵体平滑肌细胞的端粒酶活性。结果(1)大鼠阴茎组织中NO量、NOS活性均先升高后降低,各月龄组间有显著差异。阴茎组织cGMP含量逐渐降低,各月龄组间差别显著；(2)随龄增加,平滑肌纤维逐渐减少,胶原纤维增多,粗大成团,窦状隙变少、变窄：(3)大鼠阴茎组织端粒酶活性以2月龄活性最高,随龄增加逐渐下降。人阴茎组织中无端粒酶活性。结论(1)衰老对大鼠阴茎组织结构、NO．cGMP通路及端粒酶活性有显著影响,提示衰老与ED关系密切；(2)大鼠阴茎组织有端粒酶活性,可作为研究细胞衰老与ED关系有关端粒酶的模型。     

Steroid pulse therapy impaired endothelial function while increasing plasma high molecule adiponectin concentration in patients with IgA nephropathy.

BACKGROUND: Decreased plasma adiponectin is associated with impaired endothelial function and, thereby, increased risk for cardiovascular events. Glucocorticoid (GC) affects vascular endothelial cells either favourably or harmfully depending upon the dosages and duration. We examined the effect of GC pulse therapy on vascular endothelial function. METHODS: Fourteen young patients with IgA nephropathy were evaluated for flow-mediated vasodilation (FMD), plasma levels of adiponectin both in high molecular weight (HMW adiponectin) form and in single molecular form (total adiponectin), hepatocyte growth factor (HGF), asymmetric dimethylarginine (ADMA), and high-sensitive C-reactive protein, before and after a course of GC pulse therapy. RESULTS: GC pulse therapy significantly decreased FMD (from 7.2 +/- 2.6 to 5.7 +/- 2.5%, P < 0.01). Meanwhile, plasma adiponectin levels were significantly augmented (total adiponectin: from 10.2 +/- 4.0 to 12.1 +/- 6.3 microg/ml, P < 0.05; HMW: from 6.5 +/- 3.2 to 7.7 +/- 3.3 microg/ml, P < 0.05). In parallel, elevated concentrations of serum HGF (from 0.28 +/- 0.12 to 0.63 +/- 0.38 ng/ml, P < 0.01) and plasma ADMA (from 0.45 +/- 0.07 to 0.53 +/- 0.04 nmol/ml, P < 0.05) were observed. CONCLUSIONS: GC pulse therapy impaired endothelial function while increasing plasma adiponectin levels, which may in turn restore the endothelial function in patients with IgA nephropathy.     

Diastolic function in children and adolescents on dialysis and after kidney transplantation: an echocardiographic assessment

Thirty-seven children and adolescents on renal replacement therapy (11 on haemodialysis, 14 on continuous ambulatory peritoneal dialysis and 12 after renal transplantation) were studied by echocardiography, echo-Doppler and phonocardiography. Right and left ventricular (R/L V) diastolic functions were measured by transmitral and transtricuspid flow velocities and by LV isovolumic relaxation time (LVIRT). Thirty-seven age- and sex-matched healthy subjects served as controls. R/L V diastolic dysfunction was only observed in the dialysis patients. In these patients LVIRT was prolonged. LV and RV peak inflow velocities were increased both in early (E) and late (A) diastole with a reduction in the E/A ratios. This pattern of diastolic dysfunction is compatible with the combined effects of a hypercirculatory state (volume overload, anaemia, arteriovenous fistula) and an abnormality of cardiac relaxation. The transplant patients showed no major cardiac abnormalities.

创伤后肝细胞凋亡与坏死的检测及其意义

目的 探讨严重创伤后肝细胞凋亡及坏死在急性肝功能障碍发病机制中的作用。方法复制多发性骨折合并休克的大鼠创伤模型,采用 Annexin－V－Flous、碘化丙锭(propidium iodid,PI)双标法经流式细胞仪检测创伤后各时间点肝细胞凋亡与坏死的数量变化,结合光镜、电镜和电泳观察细胞凋亡与坏死,并与肝功能变化相比较。结果创伤后早期肝细胞即发生凋亡和坏死,坏死肝细胞的数量进行性升高,与肝功能变化显著呈正相关;凋亡肝细胞在创伤后3h达高峰,部分凋亡肝细胞发生继发性坏死,其数量与肝功能变化显著正相关。结论肝细胞坏死与凋亡是严重创伤后肝功能损害的重要原因,坏死肝细胞是肝功能损害的直接因素,凋亡肝细胞通过发生继发性坏死加重肝功能损害。
