abnormal vaginal bleeding requiring intervention had no statis-tical difference between VP and WVP patients group (p=0.3074)as other complications as well(table1).Median of related days of vaginal bleeding after the procedure were 7.4days(SD8.75)in VP group and7.34days(SD8.52)in WVP group,with no statistical difference(p=0.912). Conclusions Insert a vaginal pack or not,after LEEP,do not affect the number of postoperative gynecologic intervention due to vaginal bleeding or the amount of postoperative bleed-ing days.Previous pregnancies,hormonal status,cytology or LEEP specimen characteristics did not affect the disclosure. We also could not find any risk factor associated to abnormal bleeding.Based on that,the use of vaginal pack can be omit-ted with no further complications.IGCS19-0405382LATERALLY EXTENDED ENDOPELVIC RESECTION(LEER) AND NEOVAGINE,PATIENT WITH RECTALADENOCARCINOMA AND RECURRENCE IN CERVIX,VAGINA AND PELVIC WALL:A PURPOSE OF A CASE1J Torres*,2J Saenz,3O Suescun,3M Medina,4L Trujillo.1Especialista en entrenamiento–Universidad Militar Nueva Granada–Instituto Nacional de Cancerologia,Department of Gynecologic Oncology,Bogota D.C.,Colombia;2Especialista en entrenamiento–Universidad Militar Nueva Granada–Instituto Nacional de Cancerologia,Department of Gynecologic Oncology,Bogota D.C,Colombia;3Instituto Nacional de Cancerologia, Department of Gynecologic Oncology,Bogota D.C,Colombia;4Instituto Nacional de Cancerologia,Department of Gynecologic Oncology,Bogota D.C.,Colombia10.1136/ijgc-2019-IGCS.382Objectives Exenteration is used to treat cancers of the lower and middle female genital tract in the irradiated pelvis. Höckel described laterally extended endopelvic resection (LEER)as an approach in which the resection line extends to the pelvic side wall.Methods A49-year-old patient diagnosed with rectal adenocar-cinoma10years ago,managed with chemotherapy plus radio-therapy.T umor relapse at3years,management with low abdominoperineal resection and definitive colostomy.Second relapse4years later,compromising the posterior aspect of the coccyx and right side of the pelvis with irresecability criteria, management was decided with chemotherapy with capecita-bine,oxaliplatin and bevacizumab.New relapse at2years in the cervix,vagina and pelvic wall.Images without distance disease,type LEER management with extension of pelvic floor margins and resection of muscle pubococcygeus and right lat-eral iliococcygeus with neovagina(Singapore flap)and non-continent urinary derivation with bilateral cutaneous ureteros-tomy,achieving adequate lateral margin with curative intent. During follow-up with favorable evolution.Results LEER combines at least two procedures:total mesorec-tal excision,total mesometrial resection or total mesovesical resection.It may even require resection of the pelvic wall, internal obturator muscle,pubococcygeus,iliococcygeus,coccy-geus or internal iliac vessels.In combination with neovagina, it would offer better results in non-gynecological cancer relapses.Conclusions LEER with neovagina can be offered as a new therapy to a selected subset of patients with relapse in adja-cent gynecological organs with good oncological,functional and aesthetic results.Symptom Management–Supportive Cancer CareIGCS19-0706383PHOTOBIOMODULATION AND MANUAL LYMPHDRAINAGE FOR NIPPLE NECROSIS TREATMENT INBREAST CANCER:A CASE REPORT1J Baiocchi,2L Campanholi,3G Baiocchi*.1Oncofisio,Physical Therapy,Sao Paulo,Brazil;2CESCAGE,Physical Therapy,Ponta Grossa,Brazil;3AC Camargo Cancer Center, Gynecologic Oncology,Sao Paulo,Brazil10.1136/ijgc-2019-IGCS.383Objectives Recently,breast reconstruction after mastectomywith nipple preservation became an option of breast cancer surgery.Despite its efficacy and aesthetic superiority,the nip-ple preservation is associated with several complications in the postoperative period.The photobiomodulation therapy,for-merly known as low-intensity laser therapy,demonstrated tis-sue promotion repair by cellular repair biostimulation, angiogenesis and anti-inflammatory effects.These characteris-tics suggest a potential role for repair of chronic wounds andmay be applicable in necrosis treatment.Our aim was toreport the effects of the physiotherapeutic intervention through photobiomodulation therapy in a patient with nipple necrosis after risk reducing mastectomy.Methods We report a case of a breast cancer surgery with nip-ple necrosis treated with low-level laser therapy.The patientwas a36-year-old women who developed skin nipple necrosisin the right breast after bilateral reconstructive mastectomy.She had6sessions of low-level laser therapy.Results A female subject developed a nipple necrosis of morethan40%on the right breast after mastectomy and recon-struction.She was referred to Physical Therapy(PT)and thePT sessions were composed by manual lymph drainage,man-ual therapy for de AWS,exercises of strength and flexibility, followed by LLLT with laser660nm,2joules per point atevery1cm.Therapy was implemented for12times in total,from May2016to June2016.A re-evaluation was performed monthly from July13,2016to November2017.After18 months of follow-up,the sustained effects of LLLT were found.Conclusions Low-level laser therapy is effective for the skin cicatrization after nipple necrosis.IGCS19-0446384CONTRACEPTION AND FERTILITY COUNSELING INPATIENTS RECEIVING CHEMOTHERAPY1A Elnaggar*,2A Calfee,1LB Daily,2T Hasley,1T Tillmanns.1West Cancer Center and Research Institute,Gynecologic Oncology,Memphis,USA;2University of Tennessee Health Science Center,Obstetrics and Gynecology,Mempis,USA10.1136/ijgc-2019-IGCS.384Objectives Cancer care advances allow more patients to pursue fertility.Unfortunately,treatments may have detrimental effectson fertility and fetus should pregnancy occur.This study examines physician documentation and patient perceptions of fertility and contraception counseling. on December 24, 2023 by guest.

VCS检测技术名词解释
VCS检测技术原理是集三种物理学检测技术于一体,在细胞处于自然原始的状态下对其进行多参数分析。
V (Volume)代表细胞的体积,用低频电流准确分析细胞体积的测量方法;C (Conductivity)代表高频电导性,采用高频电磁探针原理测量细胞内部结构间的差异,即电流通过细胞膜传导过细胞,细胞核的化学组分使电流传导性产生变化从而反映出细胞内含物信息,进而区分体积相近而内部性质不同的细胞群体;S (Scatter)代表光散射,即细胞被一束激光在不同方向和角度测定各种白细胞产生散射光的特征,就是采用氯氖激光源发出的单色激光扫描每个细胞,收集细胞10°~70°出现的散射光信号,探测细胞内核分叶状况和胞浆中的颗粒情况,提供细胞的信息,区分出颗粒特性不同的细胞群体。
VCS参数什么是VCS?VCS是版本控制系统(Version Control System)的缩写。
它是一种用于记录和管理软件开发过程中代码版本变化的工具。
VCS允许多个开发者协同工作,并且可以跟踪每个开发者对代码的修改,以及恢复到之前的任何一个版本。
VCS参数的作用在使用VCS时,我们可以使用一些参数来控制和管理代码版本的变化。
这些参数可以帮助我们更好地管理代码库,追踪变更历史,并与其他开发者共享和合并代码。
以下是一些常见的VCS参数及其作用:1. commitcommit命令用于将当前修改保存为一个新的版本。
通过提交(commit)操作,我们可以记录下每次修改所引入的变化,并为每个版本添加注释说明。
$ git commit -m "Add new feature"在上面的示例中,-m参数用于添加提交消息。
提交消息应该清晰明了地描述这次提交所做的修改内容。
2. checkoutcheckout命令用于切换到不同的分支或恢复到之前某个版本。
通过checkout操作,我们可以在不同分支之间进行切换或回滚到先前的某个状态。
$ git checkout branch-name$ git checkout commit-hash在上面的示例中,branch-name是要切换到的分支名称,commit-hash是要恢复到的特定提交的哈希值。
3. branchbranch命令用于创建、查看和删除分支。
分支可以让我们在不影响主线开发的情况下,进行独立的实验和开发。
$ git branch new-branch$ git branch -d branch-to-delete在上面的示例中,new-branch是要创建的新分支名称,branch-to-delete是要删除的分支名称。
4. mergemerge命令用于将一个分支合并到另一个分支中。
通过合并操作,我们可以将不同分支上的修改合并为一个统一的版本。
vcs电解电容VCS(VariableCapacitanceSystem)电解电容是一种液体电解电容(LDC)的一种,属于变容量处理系统(VCS)的一种。
它是由一个金属容器内液体电解质,由一个金属膜组成的电容器,金属膜组构造形成双金属电容片,其中膜由一层氧化物分层,构成电解质电容组成液体电解电容。
VCS电解电容通常由一个容量电池或非线性电容连接而成,它的容量可根据需要以步进的方式进行调整。
VCS电解电容的特点VCS电解电容的特点在于它可以通过调整液体电解质的浓度来调节它的容量,从而达到电容器的可调容量的要求。
由于它的金属容器内充满液体电解质,其结构比传统固体电解电容更加复杂。
VCS电解电容由于拥有灵敏度高、工作电压低、温度稳定性高、稳定性佳、体积小、可靠性强等特点,在电子设备中得到了广泛的应用。
一般来说,VCS电解电容的容量可以在0.001-10uF之间进行调节,容量的调节范围比传统的固体电容要大得多。
VCS电解电容的应用VCS电解电容在电子设备中得到了广泛的应用,主要用于滤波器、放大电路、调节电路、噪声补偿、信号处理等电子设备中,也可用于高频开关电源、数字电路和精密仪器仪表中。
VCS电解电容的优势VCS电解电容是一种电解电容,其优点在于它可以根据电池的变化而调节它的容量,从而达到电路的需求,它的容量调节范围比传统的固定电容大得多,可以更好的满足电路的要求。
另外,VCS电解电容具有灵敏度高、工作电压低、温度稳定性高、稳定性佳、体积小、可靠性强等特点,在电子设备中的应用越来越广泛。
VCS电解电容的局限性VCS电解电容虽然有着许多优点,但它也存在一些局限性,首先,它的制作工艺比传统固定电容要复杂,生产成本更高;其次,由于VCS电解电容的金属容器内充满液体电解质,使得其焊接、安装、维护更加复杂,操作起来也更加麻烦。
最后,由于加工技术的限制,VCS 电解电容的容量只能在一定的范围内进行调整,无法进行大范围的调整。
vcs(鞘层电容电压
"VCS" 在电子学和半导体领域中并不是一个标准的术语或缩写,因此"VCS(鞘层电容电压)" 不是一个普遍认可的概念或术语。
不过,我可以尝试根据上下文来推测其可能的意义。
在半导体物理和器件模拟中,"鞘层"(Sheath)通常是指紧邻半导体表面的电荷耗尽区域,通常是由于表面态或界面态的影响而形成的。
而电容和电压之间的关系则是基础的电子学概念,通常用于描述电路中不同节点之间的电荷存储和电压变化。
如果"VCS" 是指某种特定的电压,那么它可能是与鞘层电容相关的电压。
例如,它可能是在某个特定条件下,鞘层电容所存储的电压值。
然而,这仅仅是一个猜测,没有更多的上下文信息,很难确定"VCS(鞘层电容电压)" 的确切含义。
为了更准确地理解"VCS(鞘层电容电压)" 的含义,建议查阅相关的专业文献、教科书或咨询相关领域的专家。
同时,如果"VCS" 是一个特定领域或技术中的术语,那么了解该领域或技术的背景知识也会有助于理解其含义。
