目的:探讨绝经后妇女高级别宫颈上皮内瘤变行宫颈环形电切术(LEEP)诊治的临床价值。方法:选择2017年2月-2018年12月于北京妇产医院妇科微创中心因宫颈高级别鳞状上皮内病变(HSIL)行LEEP术的患者共142例,其中绝经组40例,未绝经组102例。收集2组患者的液基薄层细胞学检查(TCT)、高危型人乳头瘤病毒(HPV)检测、阴道镜检查及其活检病理结果、LEEP术后病理结果、切缘病变情况,并将上述检查结果进行组间比较。结果:2组患者阴道镜下宫颈转化区类型比较,差异有统计学意义(χ~2=28.658,P=0.000)。绝经组阴道镜活检与LEEP术后病理符合率为50.00%(20/40),未绝经组符合率为51.96%(53/102),2组差异无统计学意义(χ~2=0.044,P=0.854)。绝经组1例LEEP术后病理升级为宫颈癌,未绝经组1例LEEP术后病理升级为原位腺癌。绝经组术后病理切缘阳性8例(20.00%),未绝经组术后病理切缘阳性16例(15.69%),2组比较差异无统计学意义(χ~2=0.381,P=0.537)。2组患者术后TCT检查比较及高危型HPV感染情况比较,差异均无统计学意义(均P>0.05)。结论:LEEP手术适用于宫颈无明显萎缩的绝经后妇女高级别宫颈上皮内瘤变的诊治,以避免对宫颈病变的漏诊和过度治疗。     

Long-term effect of estradiol implants on the female urinary tract during the climacteric

The incidence of lower urinary tract dysfunction increases during the climacteric, and there is embryological, biochemical and epidemiologic evidence to suggest that depleted estrogen status is at least partially responsible. Twelve climacteric women underwent full assessment before and 1 year after treatment with a 50 mg subcutaneous estradiol implant +5 mg norethisterone for 7 days per month. Assessment consisted of a symptoms questionnaire, midstream urine sample, uroflowmetry, videocystourethrography with pressure flow studies, and urethral pressure profilometry. Subjectively, only the symptom of nocturia significantly improved. There was no change in flow variables but there was a significant decrease in residual urine and the degree of bladder base descent. Cystometric capacity was slightly but significantly decreased, and two patients developed genuine stress incontinence whilst on treatment. Nonetheless, there was a significant improvement in urethral pressures at rest but not under stress. This effect was predominantly in the proximal urethra. These data do not support the contention that estrogen replacement therapy is beneficial for lower urinary tract dysfunction during the climacteric.     

Specific Changes of Urinary Excretion of Cross-Linked N-Telopeptides of Type I Collagen in Pre- and Postmenopausal Women: Correlation with Other Markers of Bone Turnover

Urinary excretion of cross-linked N-telopeptide of type I collagen (NTx) has been reported to be a specific marker of bone resorption [18]. We assessed a new immunoassay for NTx as an indicator of changes in bone resorption caused by spontaneous menopause and compared cross-sectionally the levels of urinary NTx, hydroxylysylpyridinoline (HP), lysylpyridinoline (LP), hydroxyproline (OH-Pr), other serum biochemical indices, and lumbar spine and proximal femur bone mineral density (BMD). Eighty-one Japanese women aged 22–77 participated in this study; 36 were premenopausal and 45 were postmenopausal. Urinary HP, LP, and NTx stayed at low levels in the premenopausal period and rose 21%, 30%, and 67% in the postmenopausal period, respectively. The rise in LP and NTx was statistically significant (P < 0.01), suggesting that NTx is mostly released from bone matrix when bone resorption is accelerated. When premenopausal women were divided into two age groups and postmenopausal women were divided into two groups according to years since menopause (YSM) there were significant differences in LP and NTx between women <4 YSM and women aged <40 and those women aged 41+ (P < 0.01 and P < 0.05, respectively). A significant 110% increase in urinary NTx and a 48% increase in urinary LP were observed in postmenopausal women compared with age-matched premenopausal women aged 45–55. All biochemical markers other than serum PTH correlated significantly with each other (r = 0.243–0.858, P < 0.05–0.0001). Urinary NTx inversely correlated with lumbar spine BMD. When postmenopausal women were divided into three groups, the correlation between bone resorption and formation markers in women 0-1 YSM was greater than in women 2–10 YSM and in women 11 + YSM, indicating that resorption and formation are coupled at the early postmenopausal period. We conclude that urinary NTx is responsive to changes in bone metabolism caused by estrogen deficiency and may be a more sensitive and specific marker than HP, LP, or OH-Pr in the early postmenopausal years.

Neuroendocrine and clinical effects of transdermal 17β-estradiol in postmenopausal women

The neuroendocrine and clinical effects of transdermal 17β-estradiol (rated at 50 μg/day; TTS 50) were studied in 40 postmenopausal women; ten additional postmenopausal women did not receive any drugs. The changes in LH and rectal temperature induced by the infusion of the opioid antagonist naloxone (10 mg i.v. bolus plus 10 mg/h for 4 h) were used to evaluate the central activity of endogenous opioid peptides. TTS 50 increased opioid activity, as evidenced by the restoration of the LH response (P < 0.01) and the enhancement of the hypothermic effect (P < 0.05) of naloxone. A greater reduction in hot flushes was observed in TTS 50-treated subjects than in untreated women, with the maximal effect of TTS 50 achieved after 3 months of therapy. TTS 50 did not modify the concentrations of circulating lipids, glucose or liver enzymes but reduced the biochemical parameters indicative of bone reabsorption. Bone density of the distal radius significantly increased during TTS 50 (P < 0.02), reaching its maximum value after 6 months of therapy. Thereafter bone density declined, but more slowly than in untreated women.

Our data suggest that TTS 50 has marked neuroendocrine effects, that it diminishes the incidence of hot flushes and reduces bone demineralization. By contrast, it has a very little, if any, metabolic impact on the liver or on glucose and lipid metabolism.

北京市房山区绝经前后妇女骨代谢情况报告

测定北京房山区１４４例绝经前后妇女桡骨骨密度值及４３例绝经妇女血清钙、雌激素、降钙素、甲状旁腺素值。结果表明：随着年龄和绝经年限的增加，骨密度值显著下降。血清钙各年龄组变化不大。雌激素、降钙素绝经后逐渐降低，甲状旁腺素明显增加，多因素回归分析提示，年龄、绝经年限、孕次、人工流产次数、服用营养补品、经济水平、雌激素、甲状旁腺素是影响骨密度的主要因素。
