同型半胱氨酸与绝经后女性颈动脉粥样硬化的相关性研究

目的 研究同型半胱氨酸(homocysteine,Hcy)是否为绝经后女性颈动脉粥样硬化的独立风险因素。 方法 对2017年12月—2018年12月北京协和医院健康体检的1 204名55岁以上绝经后女性,进行Hcy检测和颈动脉超声检查。使用多变量logistic回归方法分析Hcy及其他传统风险因素对颈动脉粥样硬化的影响。 结果 Hcy平均值(12.4±3.3)μmol/L,高Hcy血症176人(14.62%)。Hcy与年龄和BMI正相关(分别r=0.19,P<0.001;r=0.11, P<0.001)。颈动脉粥样硬化患者的Hcy显著升高(Z=-2.56,P=0.011)。logistic回归显示,对于颈动脉粥样硬化只有年龄(OR=1.11,95%CI:1.09~1.14)和收缩压(OR=1.02,95%CI:1.01~1.02)是独立风险因素;对颈动脉斑块形成年龄(OR=1.10,95%CI:1.08~1.12)、收缩压(OR=1.02,95%CI:1.01~1.03)、糖化血红蛋白(OR=1.27,95%CI:1.07~1.50)和高血压病史(OR=1.40,95%CI:1.06~1.87)是独立危险因素。 结论 在绝经后女性,Hcy不是动脉粥样硬化发生的独立风险因素,筛查高Hcy血症在预防该人群颈动脉粥样硬化的意义仍需进一步证明。     

Ospemifene plus fractional CO2 laser: a powerful strategy to treat postmenopausal vulvar pain

Abstract

This study is a single-center, retrospective analysis of postmenopausal women presenting with dyspareunia and vulvar pain, aiming to evaluate relative effectiveness of vestibular CO₂ laser therapy as a treatment. Three monthly sessions of laser were performed to each patient and thereafter a three-months follow-up was stablished. A total number of 72 patients undergoing vestibular laser treatment were recruited from patient files in the period between 2016 and 2018. Among these, 39 women also received a concomitant treatment with ospemifene (60?mg/day) during the study period. There was a statistically significant reduction of all the symptoms in both groups up to the three month follow-up. Regarding dryness and dyspareunia, the relief tent to be more prominent in the ospemifene?+?laser group at all follow-ups and remained statistically significant at three-month follow-up. Specifically, vestibular dryness was significantly lower in the ospemifene?+?laser group compared with the laser treatment group (?87% vs???34%, respectively), and the vestibular health score started declining faster in the ospemifene?+?laser group. Although, additional research is needed to understand the mechanism of action, our data shows that a combination regimen of laser and ospemifene may improve clinical effectiveness for long-term treatment of symptoms associated with the under-recognized genitourinary syndrome of menopause.     

An updated review on pathophysiology and management of burning mouth syndrome with endocrinological,psychological and neuropathic perspectives

Burning mouth syndrome (BMS) is a chronic oro‐facial pain disorder of unknown cause. It is more common in peri‐ and post‐menopausal women, and sex hormone dysregulation is believed to be an important causative factor. Psychosocial events often trigger or exacerbate symptoms, and persons with BMS appear to be predisposed towards anxiety and depression. Atrophy of small nerve fibres in the tongue epithelium has been reported, and potential neuropathic mechanisms for BMS are now widely investigated. Historically, BMS was thought to comprise endocrinological, psychosocial and neuropathic components. Neuroprotective steroids and glial cell line–derived neurotrophic factor family ligands may have pivotal roles in the peripheral mechanisms associated with atrophy of small nerve fibres. Denervation of chorda tympani nerve fibres that innervate fungiform buds leads to alternative trigeminal innervation, which results in dysgeusia and burning pain when eating hot foods. With regard to the central mechanism of BMS, depletion of neuroprotective steroids alters the brain network–related mood and pain modulation. Peripheral mechanistic studies support the use of topical clonazepam and capsaicin for the management of BMS, and some evidence supports the use of cognitive behavioural therapy. Hormone replacement therapy may address the causes of BMS, although adverse effects prevent its use as a first‐line treatment. Selective serotonin reuptake inhibitors (SSRIs) and serotonin and noradrenaline reuptake inhibitors (SNRIs) may have important benefits, and well‐designed controlled studies are expected. Other treatment options to be investigated include brain stimulation and TSPO (translocator protein 18 kDa) ligands.     

按压骨穴调节围绝经期妇女心脏植物神经功能的研究

目的观察按压骨穴对围绝经期妇女心脏植物神经功能的影响。方法设按压骨穴组30例、空白对照组30例。用美国BraemarDL700型动态心电检测仪,检测试验前后的心率变异性(HRV):TF代表总频,LF代表交感神经活性,HF代表迷走神经活性,LF/HF代表交感神经与迷走神经均衡性。结果按压骨穴后4项指标均有显著下降(P<0.01,P<0.05)。空白对照组变化不显著(P>0.05)。骨穴组4项指标的变化率与对照组比较均有显著性差异(P<0.01)。结论按压骨穴有抑制心脏交感神经活性的良性调整作用,此效应具有相对的特异性。

Gingival crevicular fluid IL-8: correlation with local IL-1β levels and patient estrogen status

Gingival crevicular fluid (GCF) IL-8 and IL-1,1β levels were determined by sandwich enzyme-linked immunosorbent assays. Associations between IL-8 and IL-1β GCF levels, and between these cytokines and patient estrogen status were evaluated. IL-8 and IL-1β were detected more frequently and in higher amounts/30 s GCF sample in estrogen-deficient patients than in estrogensufficient patients. IL-8 and IL-1β GCF levels were significantly correlated. These lindings suggest that GCF IL-8 levels are associated with patient estrogen status and local IL-1β concentrations.

Effect of female sex hormone supplementation and withdrawal on gastrointestinal and colonic transit in postmenopausal women

Females are disproportionately affected by constipation, which is often aggravated during pregnancy. Bowel function also changes during the luteal phase of the menstrual cycle. The aim was to compare the effects of acute administration of female sex steroids on gastric emptying, small bowel transit and colonic transit in healthy postmenopausal subjects. A second aim was to determine whether withdrawal of the hormones was associated with a change in transit. Forty-nine postmenopausal females were randomized to receive for 7 days 400 mg day(-1) micronized progesterone, 0.2 mg day(-1) oestradiol, combination of the two, or placebo. Treatment groups were balanced on age. Participants underwent whole gut transit measurement by scintigraphy using a 99m-labeled technetium-egg meal and 111-labeled indium-charcoal via a delayed-release capsule. Transit measurement was repeated after withdrawal of the study medications. The primary endpoints were ascending colon (AC) emptying half-life time (t1/2) and colonic geometric centre (GC) at 24 h. Secondary analysis variables were GC at 4 and 48 h, gastric emptying t1/2 and colonic filling at 6 h. There was a significant overall effect of progesterone on colonic transit with shorter AC emptying t1/2 and significantly greater colonic GC at 48 h. No transit endpoints were altered by oestradiol or combined hormonal treatment relative to placebo. Oestradiol and progesterone resulted in looser stool consistency. Withdrawal of the hormone supplement was not associated with significant alteration in transit. Micronized progesterone does not retard colonic transit in postmenopausal females.     

Endocrinology: Gonadotrophins and prolactin rise after bilateral oophorectomy for benign conditions

The aim of this study was to analyse the changes in folliclestimulating hormone (FSH), luteinizing hormone (LH) and prolactinconcentrations in the 3 months following oophorectomy in pre-menopausalwomen operated on for benign gynaecological conditions. Includedin this analysis were 21 women (mean age 47 years, range 46–52)who underwent bilateral oophorectomy plus hysterectomy for fibroidsor ovarian cysts. Plasma concentrations of FSH, LH and prolactinwere measured before and on days 2, 4, 6, 14 and 30 after surgery;in 10 cases measurements were made on day 60, and in five caseson day 90 after surgery. Hormone concentrations were measuredin duplicate daily samples, and immunoenzymatic assay kits wereused for all the immunoassays. The FSH and LH concentrationsincreased constantly after surgery. Mean prolactin concentrationsalso increased from 12.1 ng/ml before surgery to 31.5 ng/mlon day 14 after bilateral oophorectomy, but decreased thereafterto 18.2 ng/ml on day 30, 10.9 ng/ml on day 60 and 6 ng/ml onday 90. In conclusion, transient (2–3 weeks) increasedprolactin concentrations are observed after surgical castration.
