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.     

杜元灏教授针刺治疗失眠经验

失眠是由各种原因导致的入睡困难和(或)睡眠维持困难的睡眠障碍,主要特征是睡眠感不满意,属于中医学"不得眠""不寐"范畴。传统多从心、肝、胆、脾、胃、肾论治该病,杜元灏教授认为脏腑机能失调,气血不和,阳不能入阴,阴不能涵阳,神不守舍而致失眠。重视"脑为元神之腑"的理论,且因督脉入络脑,夹脊穴为五脏六腑之气转输、流注之处,杜教授多强调从脑、督脉以及夹脊穴论治失眠,为针刺治疗失眠提供新思路。     

百乐眠胶囊治疗失眠症的临床研究

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.
