    阴道放电是初潮前女孩常见的妇科主诉。然而,持续存在时,必须怀疑阴道内异物(FB)。我们报告了一例转诊的4岁女孩,有5个月的持续恶臭阴道分泌物史。临床检查证实脓性阴道分泌物,还有阴道肉芽肿.一个硬,直肠指检术通过直肠前壁感觉到阴道内物体。骨盆X线平片显示不透射线的物体,其阴道内位置已通过超声检查得到证实。患者接受肉芽肿切除加FB切除和抗生素治疗。12个月的随访并不显著。
    UNASSIGNED: Vaginal discharge is a common gynaecologic complaint in pre-menarchal girls. However, an intravaginal foreign body (FB) must be suspected when it is persistent. We report the case of a referred 4-year-old girl with a 5-month history of persistent foul-smelling vaginal discharge. Clinical examination confirmed purulent vaginal discharge, along with a vaginal granuloma. A hard, intravaginal object was felt through the anterior rectal wall on digital rectal examination. A plain pelvic X-ray revealed a radiopaque object whose intravaginal position was confirmed by ultrasonography. The patient underwent granuloma excision plus FB removal and antibiotic treatment. The 12-month follow-up was unremarkable.

    背景:月经周期中阴道微生物群的组成是动态的,一些女性保持正常或生态失调,而另一些女性则在这些状态之间过渡。是什么定义了这些动态,这些差异是微生物组固有的还是主要由宿主驱动的,目前尚不清楚。为了解决这个问题,我们的特征是49个健康,年轻女性通过月经周期中每日阴道拭子的宏基因组测序。我们对阴道微生物组的动态进行了分类,并评估了宿主行为以及物种中微生物组差异的影响,应变,基因,和噬菌体水平。
    结果:根据月经周期中社区状态类型(CST)的每日变化,阴道微生物组被分为四种阴道群落动力学(VCD),并在分类工具中报告,名为VALODY:恒定的优生,恒定的生态失调,月经相关,和不稳定的生态失调。丰富的细菌,噬菌体,并比较了四种VCD之间的细菌基因含量。即使分配给相同的CST,具有不同VCD的女性在相对噬菌体丰度和细菌组成方面也显示出显着差异。VCD不稳定的女性的噬菌体计数较高,并且更有可能以L.iners为主。他们的加德纳菌。菌株也更有可能携带细菌素编码基因。
    结论:VCD提出了一种新颖的时间序列分类,突出了不同程度的阴道生态失调的复杂性。了解噬菌体基因丰度和存在的基因组菌株的差异,可以更深入地了解永久性生态失调的开始和维持。应用VCD来进一步表征不同类型的微生物组动态,可以对疾病进行调查,并能够在个体和群体水平上进行比较。根据我们的数据,为了能够将生态失调样本分类到准确的VCD中,临床医生需要两到三个周期中期样本和两个月经期间样本。在未来,重要的是要解决短暂性VCD是否与具有相似临床结局的持续性生态失调具有相似的风险特征.该框架可以帮助跨学科的转化团队破译阴道微生物组在女性健康和生殖中的作用。视频摘要。
    BACKGROUND: The composition of the vaginal microbiota during the menstrual cycle is dynamic, with some women remaining eu- or dysbiotic and others transitioning between these states. What defines these dynamics, and whether these differences are microbiome-intrinsic or mostly driven by the host is unknown. To address this, we characterized 49 healthy, young women by metagenomic sequencing of daily vaginal swabs during a menstrual cycle. We classified the dynamics of the vaginal microbiome and assessed the impact of host behavior as well as microbiome differences at the species, strain, gene, and phage levels.
    RESULTS: Based on the daily shifts in community state types (CSTs) during a menstrual cycle, the vaginal microbiome was classified into four Vaginal Community Dynamics (VCDs) and reported in a classification tool, named VALODY: constant eubiotic, constant dysbiotic, menses-related, and unstable dysbiotic. The abundance of bacteria, phages, and bacterial gene content was compared between the four VCDs. Women with different VCDs showed significant differences in relative phage abundance and bacterial composition even when assigned to the same CST. Women with unstable VCDs had higher phage counts and were more likely dominated by L. iners. Their Gardnerella spp. strains were also more likely to harbor bacteriocin-coding genes.
    CONCLUSIONS: The VCDs present a novel time series classification that highlights the complexity of varying degrees of vaginal dysbiosis. Knowing the differences in phage gene abundances and the genomic strains present allows a deeper understanding of the initiation and maintenance of permanent dysbiosis. Applying the VCDs to further characterize the different types of microbiome dynamics qualifies the investigation of disease and enables comparisons at individual and population levels. Based on our data, to be able to classify a dysbiotic sample into the accurate VCD, clinicians would need two to three mid-cycle samples and two samples during menses. In the future, it will be important to address whether transient VCDs pose a similar risk profile to persistent dysbiosis with similar clinical outcomes. This framework may aid interdisciplinary translational teams in deciphering the role of the vaginal microbiome in women\'s health and reproduction. Video Abstract.

    背景:金黄色葡萄球菌(S.金黄色葡萄球菌)经常定植在人类皮肤上,上呼吸道和生殖道。在女性生殖道,它可以在阴道分娩过程中传递给新生儿,导致普通的定植,或新生儿感染,特别是脐残端败血症,烫伤皮肤综合征,关节炎,或菌血症/败血症。这些感染是由葡萄球菌毒力因子介导的,例如(i)葡萄球菌肠毒素A,B,C,D,E由海编码,seb,sec,SED,看到基因,(ii)由eta和etb基因编码的剥脱性毒素A和B,(iii)由tst基因编码的毒性休克综合征毒素1(TSST-1),(iv)Panton-Valentine杀白细胞素(PVL)由pvl基因编码,和(v)由hla和hld基因编码的溶血素α和δ,分别。我们确定了该人群中具有一个或多个毒力因子基因的金黄色葡萄球菌和耐甲氧西林金黄色葡萄球菌(MRSA)的患病率。
    方法:这是一项横断面研究,使用来自乌干达氯己定(CHX)临床试验研究的85株金黄色葡萄球菌分离物。分离株是通过培养1472名分娩妇女的阴道拭子(VS)获得的,冷冻在零下80摄氏度,然后解冻,亚培养,并测试了选定的毒力基因海,seb,sec,SED,看到eta,ETB,tst,pvl,hla和hld,和甲氧西林抗性决定基因(mecA)。使用SPSS版本20对数据进行分析。
    结果:在85株金黄色葡萄球菌分离株中,13株(15.3%)对一种或多种毒力因子基因呈阳性,如下:pvl9/85(10.6%),hld5/85(5.9%),sea1/85(1.2%)和seb基因1/85(1.2%)。其他毒力基因(秒,SED,see,eta,ETB,在任何分离物中均未检测到hla和tst)。在55.3%(47/85)的分离物中检测到MRSA,但其中只有两个携带pvl毒力基因。
    结论:这项研究表明,15%的金黄色葡萄球菌定植在乌干达中部分娩的母亲的女性下生殖道携带一个或多个毒力基因,主要是pvl,提示新生儿在产妇产道中获得的金黄色葡萄球菌感染的可能性。超过一半的分离物是MRSA。
    BACKGROUND: Staphylococcus aureus (S. aureus) often colonizes the human skin, upper respiratory and genital tracts. In the female genital tract, it can be passed on to the newborn during vaginal delivery leading to either ordinary colonization, or neonatal infections notably umbilical stump sepsis, scalded skin syndrome, arthritis, or bacteraemia/sepsis. These infections are mediated by staphylococcal virulence factors such as (i) Staphylococcal Enterotoxins A, B, C, D, and E encoded by the sea, seb, sec, sed, see genes, (ii) Exfoliative Toxins A and B encoded by the eta and etb genes, (iii) Toxic Shock Syndrome Toxin 1 (TSST-1) encoded by the tst gene, (iv) Panton-Valentine Leukocidin (PVL) encoded by the pvl gene, and (v) Hemolysins alpha and delta encoded by the hla and hld genes, respectively. We determined the prevalence of S. aureus possessing one or more virulence factor genes and of methicillin resistant Staphylococcus aureus (MRSA) in this population.
    METHODS: This was a cross-sectional study, which used 85 S. aureus isolates from the Chlorohexidine (CHX) clinical trial study in Uganda. The isolates had been obtained by culturing vaginal swabs (VS) from 1472 women in labour, frozen at minus 80oC, then thawed, sub-cultured, and tested for the selected virulence genes sea, seb, sec, sed, see eta, etb, tst, pvl, hla and hld, and for the methicillin resistance determining gene (mecA). Data were analyzed using SPSS version 20.
    RESULTS: Of the 85 S. aureus isolates 13 (15.3%) were positive for one or more virulence factor genes, as follows: pvl 9/85 (10.6%), hld 5/85 (5.9%), sea 1/85 (1.2%) and seb genes 1/85 (1.2%). The other virulence genes (sec, sed, see, eta, etb, hla and tst) were not detected in any of the isolates. MRSA was detected in 55.3% (47/85) of the isolates, but only two of these carried the pvl virulence gene.
    CONCLUSIONS: This study demonstrated that 15% of the S. aureus colonizing the female lower genital tract of mothers in labour in central Uganda carried one or more virulence genes, mostly pvl, indicating potential for newborn infection with S. aureus acquired in the maternal birth canal. More than half of the isolates were MRSA.

    肠沙门氏菌亚种。由于其与食源性疾病的关联,肠内血清肠炎(SE)是家禽业的全球关注焦点。传播通过跨血管途径发生,该途径从输卵管定植并上升到卵巢开始。虽然有研究表明胞嘧啶-磷酸-鸟嘌呤寡脱氧核苷酸(CpG-ODN)与先天免疫应答的增加,关于使用CpG-ODN的阴道内治疗的研究有限。先前的研究表明,刺激CpG-ODN可以诱导阴道细胞培养物中抗菌肽禽β-防御素(AvBDs)的产生,关于使用阴道内治疗诱导先天免疫系统的信息有限,特别是在KampungUngulBalitbangtan(KUB-1)鸡(家鸡)中。这项研究调查了当受到SE攻击时,阴道内CpG-ODN刺激对KUB-1鸡卵巢和输卵管的先天性免疫应答的影响。共39只KUB-1鸡分为四组即T1(用CpG-ODN处理,n=12),T2(SE组,n=12),T3(CpG-ODN和SE,n=12),和控制(不含CpG-ODN和SE,n=3)。从阴道内(PI)接种后第1天至第4天观察鸡。结果表明,阴道内CpG-ODN治疗通过toll样受体(TLR)21调节AvBD10的产生,白细胞介素(IL)1B和IL10发挥相互作用,提供对这种治疗方法预防家禽中的传染性沙门氏菌病的潜力的见解。这项研究的新颖性为当前的知识体系增添了宝贵的见解。
    Salmonella enterica subsp. enterica serovar Enteritidis (SE) is a global concern for the poultry industry due to its association with foodborne illnesses. The transmission occurs through the transovarial route which initiates from colonization in oviducts and ascending to ovaries. Though there are studies on cytosine-phosphate-guanine oligodeoxynucleotide (CpG-ODN) and the increase of innate immune response, there is limited research on the intravaginal treatment using CpG-ODN. Previous studies have shown that stimulating CpG-ODN can induce the production of antimicrobial peptide avian beta-defensins (AvBDs) in vaginal cell cultures, there is limited information on the use of intravaginal treatment to induce the innate immune system, particularly in the Kampung Unggul Balitbangtan (KUB-1) chickens (Gallus gallus domesticus). This study investigates the impact of intravaginal CpG-ODN stimulation on the innate immune response in KUB-1 chicken ovaries and oviducts when challenged to SE. A total of 39 KUB-1 chickens were divided into four groups namely T1 (treated with CpG-ODN, n=12), T2 (SE group, n=12), T3 (CpG-ODN and SE, n=12), and Control (without CpG-ODN and SE, n=3). Chickens were observed from day 1 to 4 post-intravaginal (PI) inoculation. The results suggest that intravaginal CpG-ODN treatment modulates AvBD10 production through toll-like receptor (TLR)21, with interleukin (IL)1B and IL10 playing reciprocal roles, providing insights into the potential of this treatment to prevent transovarial Salmonellosis in poultry. The novelty of this study adds valuable insights to the current body of knowledge.

    用于结直肠癌的阴道自然腔道内镜手术(vNOTES)利用经阴道途径进行肠动员,血管蒂结扎,肿瘤切除术,肠吻合,随着随后的经阴道自然口标本提取(NOSE),减少或消除经腹通路的需要。在这份报告中,我们描述了vNOTES右半结肠切除术治疗盲肠癌的技术,体内吻合和经阴道鼻,包括一步一步的手术视频。该患者为59岁的中国女性(体重指数32.0kg/m2),患有cT3N0M03cm盲肠腺癌。通过插入双环伤口保护器来创建后结肠切除术。vNOTESD2右半结肠切除术与完全吻合的体内吻合术通过自制的经阴道手套口进行,使用超长的刚性仪器。一个10毫米,通过经脐端口使用30°刚性腹腔镜进行手术可视化,没有额外的经皮套管针。操作困难与仪器到达不理想有关,缺乏三角测量,以及在受限访问空间内的频繁冲突。手术时间为300分钟,50毫升的失血。术后疼痛轻微。术后第2天发生肠功能恢复,术后第3天出院。手术后1周,患者恢复正常的日常活动和饮食。自我报告的化妆品满意度得分优异。随访2个月无手术并发症。vNOTES右半结肠切除术联合体内吻合术在高度选择的结肠癌患者中是安全可行的。操作人员应精通常规腹腔镜结肠切除术和经阴道NOSE。需要更多的vNOTES技术经验来确定最佳实践。
    Vaginal natural orifice transluminal endoscopic surgery (vNOTES) for colorectal cancer utilizes transvaginal access for bowel mobilization, vascular pedicle ligation, oncological resection, and bowel anastomosis, along with subsequent transvaginal natural orifice specimen extraction (NOSE), reducing or eliminating the need for transabdominal access. In this report, we describe the technique of vNOTES right hemicolectomy for cecal cancer, with intracorporeal anastomosis and transvaginal NOSE, including a step-by-step operative video. The patient was a 59-year-old Chinese female (body mass index 32.0 kg/m2) with a cT3N0M0 3 cm cecal adenocarcinoma. Posterior colpotomy was created with insertion of a dual-ring wound protector. vNOTES D2 right hemicolectomy with a fully stapled intracorporeal anastomosis was performed via a homemade transvaginal glove port, using extra-long rigid instruments. A 10 mm, 30° rigid laparoscope was used for operative visualization through a transumbilical port, without additional percutaneous trocars. Operative difficulties pertained to suboptimal instrument reach, lack of triangulation, and frequent clashing within the restricted access space. Surgical duration was 300 min, with 50 ml of blood loss. There was minimal postoperative pain. Return of bowel function occurred on postoperative day 2, with discharge from hospital on postoperative day 3. The patient resumed normal daily activities and regular diet by 1-week post-surgery. Self-reported cosmetic satisfaction score was excellent. No operative complications were observed at 2 months\' follow-up. vNOTES right hemicolectomy with intracorporeal anastomosis is safe and feasible in highly selected colon cancer patients. Operators should be proficient in conventional laparoscopic colectomy and transvaginal NOSE. More experience with the vNOTES technique is required to ascertain best practices.

    背景:生命早期的微生物定植对宿主健康有重要影响,塑造免疫和代谢功能,但是对狗的这个过程的时间和特征知之甚少。本研究的目的是表征自然分娩犬幼犬肠道微生物群发育的第一步,并研究其与母体细菌菌群的关系。使用传统文化和分子分析。两种品种的60只小狗,Appenzeller牛犬(n=3水坝)和LagottoRomagnolo(n=6),住在同一个繁殖狗窝里,包括在研究中。在分娩结束时从阴道和直肠收集一式两份的拭子(用于培养和分子分析),从小狗直肠,在产妇护理之前,和环境(托儿所和分娩箱的地板)。
    结果:93.3%的胎粪样本显示细菌生长,在57.0%的病例中仅限于几个菌落。检测到粪肠球菌的高生长,这是最常见的细菌。肠球菌属是在大坝直肠和阴道中最有代表性的属之一(88.9%和55.6%,分别)。葡萄球菌属,肠球菌,埃希氏菌和变形杆菌也经常在胎粪中分离,但通常也存在于母体样本中,与普遍存在的细菌(不动杆菌,嗜冷杆菌)。在环境样本中,只发现了几种细菌,所有微生物负荷低。此外,门变形杆菌的细菌,Firmicutes,通过分子分析在胎粪中鉴定出放线菌,确认培养结果和新生儿肠道的早期定植。产妇,胎粪和环境样本具有相似的α多样性,虽然β-多样性显示了家庭之间的差异(即大坝和她的垃圾),和关联指数显示家庭成员之间和样本来源之间存在显著相关性,表明母体菌群对犬新生儿肠道的初始播种和强烈的个体大坝印记有很大的贡献。
    结论:这项研究表明,经阴道分娩的幼犬的胎粪在出生后立即具有其自身的微生物群,它是由大坝塑造的,这给她的垃圾留下了特别的印记。
    BACKGROUND: Microbial colonization during early life has a pivotal impact on the host health, shaping immune and metabolic functions, but little is known about timing and features of this process in dogs. The objectives of this study were to characterize the first step of intestinal microbiota development in naturally delivered canine puppies and to investigate its relationship with the maternal bacterial flora, using traditional culture and molecular analyses. Sixty puppies of two breeds, Appenzeller Cattle Dog (n = 3 dams) and Lagotto Romagnolo (n = 6), housed in the same breeding kennel, were included in the study. Swabs were collected in duplicate (for culture and for molecular analysis) from the dams\' vagina and rectum at the end of parturition, from puppies\' rectum, before maternal care, and from the environment (floor of the nursery and parturition box).
    RESULTS: 93.3% meconium samples showed bacterial growth, limited to a few colonies in 57.0% of cases. High growth was detected for Enterococcus faecalis, which was the most frequently isolated bacterium. The genus Enterococcus was one of the most represented in the dams\' rectum and vagina (88.9% and 55.6%, respectively). The genera Staphylococcus, Enterococcus, Escherichia and Proteus were also often isolated in meconium but were usually present in maternal samples as well, together with ubiquitous bacteria (Acinetobacter, Psychrobacter). In the environmental samples, just a few bacterial species were found, all with low microbial load. Additionally, bacteria of the phyla Proteobacteria, Firmicutes, and Actinobacteria were identified in meconium through molecular analysis, confirming the culture results and the early colonization of the newborn gut. Maternal, meconium and environmental samples had similar alpha diversity, while beta-diversity showed differences among families (i.e. a dam and her litter), and association indexes revealed a significant correlation between family members and between sample origin, suggesting a strong contribution of the maternal flora to the initial seeding of the canine neonatal gut and a strong individual dam imprint.
    CONCLUSIONS: This study showed that the meconium of vaginally delivered puppies has its own microbiota immediately after birth, and that it is shaped by the dam, which gives a specific imprint to her litter.

    使用组织病理学技术准确测量不同年龄组的阴道粘膜厚度,并研究可能影响厚度变化的因素。本研究旨在为临床医生提供阴道粘膜厚度变化的客观证据。促进患者的个性化医疗决策。方法回顾性分析华西第二大学医院348例局部阴道壁切除术患者的临床资料,四川大学,从2021年1月到2022年5月。阴道粘膜的厚度,在显微镜下精确测量上皮和固有层。第十个,25日,50岁,75,计算不同年龄组阴道粘膜厚度的第90百分位值,并绘制点线图。阴道粘膜厚度的百分位值随着年龄的增加呈下降趋势;阴道粘膜厚度与分娩次数(P=0.031)和年龄(P<0.001)呈显著相关。两者呈负相关。阴道黏膜厚度与体重指数(BMI)无显著相关性(P=0.325)。流产次数(P=0.511),妊娠时间(P=0.101),月经周期(P=0.533),或分娩类型(P=0.056);上皮厚度与年龄(P<0.001)和分娩类型(P=0.017)显着相关,两者均为负相关。此外,BMI(P=0.429),流产次数(P=0.764),交货(P=0.079),妊娠(P=0.475),和月经周期(P=0.950)与上皮厚度无关;固有层厚度仅与年龄显着相关(P=0.002),固有层厚度与BMI无明显相关性(P=0.374),流产次数(P=0.417),交货(P=0.053),妊娠(P=0.101),分娩类型(P=0.132)和月经周期(P=0.495)。此外,当年龄分割被设定为35岁和50岁时,上皮厚度和阴道黏膜厚度均与年龄显著相关(P<0.05)。当年龄阈值设定为35岁时,固有层厚度与年龄相关(P=0.007)。而当年龄阈值为50岁时,它与年龄没有很强的联系(P=0.072)。本研究基于组织病理学创新性地建立了阴道粘膜厚度的百分位参考值,为临床医生提供阴道粘膜厚度变化的客观证据,以促进患者的个性化医疗决策。研究结果表明,阴道粘膜厚度和年龄之间有很强的联系,上皮可能起主要作用,而与固有层的关联似乎不那么重要。需要进行涉及更大样本量的进一步研究,以阐明与固有层的潜在关系。
    To accurately measure the vaginal mucosa thickness across different age groups using histopathologic techniques and investigate the factors that may influence the thickness changes. This study aims to provide clinicians with objective evidence of variations in vaginal mucosal thickness, facilitating personalized medical decisions for patients. A retrospective analysis was conducted on clinical data from 348 patients who underwent local vaginal wall resection at the West China Second University Hospital, Sichuan University, from January 2021 and May 2022. The thickness of vaginal mucosa, epithelium and lamina propria was measured precisely under the microscope. And the 10th, 25th, 50th, 75th, and 90th percentile values of vaginal mucosa thickness across different age groups were counted and charted a dot-line plot. The percentile values for vaginal mucosa thickness exhibited a decreasing trend with increasing age; vaginal mucosa thickness showed significant correlations with times of delivery (P = 0.031) and age (P < 0.001), both of which were negatively associated. And vaginal mucosa thickness demonstrated no significant correlation with body mass index (BMI) (P = 0.325), times of abortions (P = 0.511), times of gestation (P = 0.101), menstrual cycle (P = 0.533), or types of delivery (P = 0.056); epithelial thickness showed significant associations with age (P < 0.001) and types of delivery (P = 0.017), both of which were negative correlations. Moreover, BMI (P = 0.429), times of abortions (P = 0.764), delivery (P = 0.079), gestation (P = 0.475), and menstrual cycle (P = 0.950) were nonassociated with epithelial thickness; lamina propria thickness displayed a significant correlation only with age (P = 0.002), and there were no obvious correlations observed between lamina propria thickness and BMI (P = 0.374), times of abortion (P = 0.417), delivery (P = 0.053), gestation (P = 0.101), types of delivery (P = 0.132) and menstrual cycle (P = 0.495). Moreover, when the age segmentation was thresholded at 35 and 50 years, both epithelial thickness and vaginal mucosa thickness were significantly correlated with age (P < 0.05). Lamina propria thickness was associated with age when the age threshold was set at 35 years (P = 0.007), whereas it showed no strong link with age when the age threshold was 50 years (P = 0.072). This study has innovatively established percentile reference values for vaginal mucosa thickness based on histopathology, furnishing clinicians with objective evidence of variations in vaginal mucosal thickness to facilitate personalized medical decisions for patients. The findings demonstrated a strong link between vaginal mucosa thickness and age, with epithelium likely playing a predominant role, while the association with lamina propria appeared to be less significant. Further research involving a larger sample size is warranted to elucidate the potential relationship with the lamina propria.

    持续的高风险人乳头瘤病毒(HRHPV)感染导致宫颈细胞鳞状上皮内病变的发展,可能导致癌症。端粒长度,端粒酶活性,和阴道微生物组的物种组成可能会影响变化的动态和癌变的过程。在本研究中,我们分析了相对端粒长度(RTL),宫颈涂片细胞和阴道微生物组中的相对hTERT表达(端粒酶成分-逆转录酶基因)。从以下组的109例患者的组织样本中分离总RNA和DNA:对照组,承运人,低度或高度鳞状上皮内病变(LSIL和HSIL,分别),和癌症。采用定量PCR方法检测端粒长度和端粒酶表达。使用形态类型标准将阴道微生物组细菌分为群落状态类型。证实了组织病理学组之间的相对端粒长度和相对hTERT表达的显着差异(分别为p<0.001和p=0.001)。在携带者和HSIL组之间发现了RTL的显着差异(padj<0.001),以及载体和LSIL基团之间(padj=0.048)。在这两种情况下,运营商的RTL较低。在HSIL组中记录到最高的相对hTERT表达水平,在携带者和HSIL组之间记录到最高的相对hTERT表达水平(p<0.001)。对于基因型16+A,鉴定了基因型和生物期之间的相关性(p<0.001)。结果表明,HPV感染的鉴定,端粒长度评估,和hTERT表达测量一起可能比单独进行的这些分析中的每一个更具预测性。
    Persistent high-risk human papillomaviruses (HR HPVs) infection leads to the development of squamous intraepithelial lesions in cervical cells that may lead to cancer. The telomere length, telomerase activity, and species composition of the vaginal microbiome may influence the dynamic of changes and the process of carcinogenesis. In the present study, we analyze relative telomere length (RTL), relative hTERT expression (gene for the telomerase component-reverse transcriptase) in cervical smear cells and vaginal microbiomes. Total RNA and DNA were isolated from tissue samples of 109 patients from the following groups: control, carrier, low-grade or high-grade squamous intraepithelial lesion (L SIL and H SIL, respectively), and cancer. The quantitative PCR method was used to measure telomere length and telomerase expression. Vaginal microbiome bacteria were divided into community state types using morphotype criteria. Significant differences between histopathology groups were confirmed for both relative telomere length and relative hTERT expression (p < 0.001 and p = 0.001, respectively). A significant difference in RTL was identified between carriers and H SIL (p adj < 0.001) groups, as well as between carriers and L SIL groups (p adj = 0.048). In both cases, RTL was lower among carriers. The highest relative hTERT expression level was recorded in the H SIL group, and the highest relative hTERT expression level was recorded between carriers and the H SIL group (p adj < 0.001). A correlation between genotype and biocenosis was identified for genotype 16+A (p < 0.001). The results suggest that identification of HPV infection, telomere length assessment, and hTERT expression measurement together may be more predictive than each of these analyses performed separately.

    鞣花酸(EA)是在许多植物及其果实中发现的酚类植物化学物质。阴道上皮细胞是女性生殖道抵御病原体入侵的第一道防线,表达抗菌肽,包括hBD2和SLPI。本研究使用人阴道上皮细胞研究了EA(1)对阴道先天免疫的体外作用,和(2)对HPV16假病毒感染的影响。在存在或不存在EA的情况下培养阴道细胞,并在转录和翻译水平测定hBD2和SLPI的表达。此外,测量各种细胞因子和趋化因子的分泌。通过CellTiter-blue和MTT测定法测定EA的细胞毒性。为了研究EA抑制HPV16感染的能力,EA用于在预附着和吸附步骤中处理HEK-293FT细胞。我们发现hBD2mRNA均显着增加(在12.5µMEA时平均2.9倍,p<0.001)和蛋白质(12.5µMEA时平均7.1倍,p=0.002)响应EA。SLPImRNA也显着增加(在25µMEA时平均1.4倍,p=0.01),但SLPI蛋白没有。EA以剂量依赖性方式诱导IL-2而不是其他细胞因子/趋化因子的分泌。EA不是细胞毒性的。在连接前步骤,EA在CC20和CC50显示出抑制HPV16假病毒的轻微趋势,但这并不重要。总之,阴道上皮细胞可以通过产生先天免疫因子来响应EA,在测试浓度下,EA不是细胞毒性的。因此,植物来源的EA可用作改善阴道健康的免疫调节剂。

Vaginal epithelial cells are the first line of defense against pathogen invasion in the female reproductive tract and express antimicrobial peptides, including hBD2 and SLPI. This study investigated the in vitro effects of EA (1) on vaginal innate immunity using human vaginal epithelial cells, and (2) on HPV16 pseudovirus infection. Vaginal cells were cultured in the presence or absence of EA, and the expression of hBD2 and SLPI was determined at both transcriptional and translational levels. In addition, secretion of various cytokines and chemokines was measured. Cytotoxicity of EA was determined by CellTiter-blue and MTT assays. To investigate the ability of EA to inhibit HPV16 infection, EA was used to treat HEK-293FT cells in pre-attachment and adsorption steps. We found significant increases in both hBD2 mRNA (mean 2.9-fold at 12.5 µM EA, p < 0.001) and protein (mean 7.1-fold at 12.5 µM EA, p = 0.002) in response to EA. SLPI mRNA also increased significantly (mean 1.4-fold at 25 µM EA, p = 0.01), but SLPI protein did not. Secretion of IL-2 but not of other cytokines/chemokines was induced by EA in a dose-dependent manner. EA was not cytotoxic. At the pre-attachment step, EA at CC20 and CC50 showed a slight trend towards inhibiting HPV16 pseudovirus, but this was not significant. In summary, vaginal epithelial cells can respond to EA by producing innate immune factors, and at tested concentrations, EA is not cytotoxic. Thus, plant-derived EA could be useful as an immunomodulatory agent to improve vaginal health.

    结果:超肉芽是阴道成形术的常见并发症,但是许多护理提供者可能不知道如何识别或治疗它。这篇简短的报告将回顾阴道成形术后的超颗粒,包括风险因素,identification,以及冲洗等治疗选择,硝酸银,和局部类固醇。
    结论:通过增加临床医生对这种普遍性并发症的认识,患者术后护理和预后可以得到改善。
    OBJECTIVE: To summarize current knowledge regarding management of hypergranulation in the context of gender-affirming vaginoplasty.
    METHODS: There have been no studies to date examining hypergranulation treatment options following vaginoplasty. Evidence from the literature on this complication in other settings and the opinions of authorities and experts in this area were used to inform this review.
    RESULTS: Hypergranulation is a common complication of vaginoplasty, but many care providers may not know how to identify or treat it. This short report will review hypergranulation after vaginoplasty, including risk factors, identification, and treatment options such as douching, silver nitrate, and topical steroids.
    CONCLUSIONS: By increasing clinicians\' knowledge of this pervasive complication, patients\' postsurgical care and outcomes can be improved.
