Definition
Refers to the layer that forms the inner wall of mammalian uterus
Estrogen can causeUterine hypertrophyThe progesterone can promote the endometrium to have special changes in the early pregnancy, or change the nature of the endometrium, so that it has the ability to produce decidua.The endometrium is covered with mucosa, which consists ofInherent layerConsists of.Mucosal epithelium isColumnar epithelium、Cuboidal epitheliumorStratified columnar epitheliumWhen estrogen is secretedepithelial cellsIt will grow and split to increase the number.The part below the mucosal epithelium in the lamina propria is called the functional layer, and epithelial cells enter it to formUterine glandAnd react to estrogen.The lower layer of the functional layer is called the basal layer, which is rich in blood vessels.
Pathological mechanism

edit
Programmaticcell death(programmedcell death,PCD), also known asApoptosis(apoptosis)。PCD occurs in many tissues and organs, including the reproductive tract.animalexperimental observation To, uterus, ovary, fallopian tube, testicle andprostatePCD occurs in all organs.Early light and electron microscopic studies show that human endometrium also hasApoptotic bodyExists.adoptagarose gel electrophoresisandDNAChromosome techniqueDNA fragmentation with PCD characteristics was found in human endometrium at the early stage of hyperplasia (6-10 days), secretory phase (25-28 days), and menstrual phase (1-5 days);However, DNA fragmentation did not occur in late hyperplasia (11-14 days), early secretion (15-20 days) and middle secretion (21-24 days).But mainly seemacromoleculeDNA。The periodic occurrence of PCD suggests that it plays an important role in regulating women's menstrual cycle.
The mechanism of PCD production in endometrium is still unclear, but it is related to thePeriodic changeofThe estrogen and progesterone receptor of endometrium, as a transcription factor, regulates the gene expression related to estrogen and progesterone, thus causing endometrial hyperplasia and secretion changes.At the same time, some polypeptide growth factors and their receptors synthesized by the uterus, such as EGF, PDGF, IGF-1, IGF-2, may be the mediators of estrogen effect, promoting cell proliferation and differentiation.It was found by immunocytochemistry that human uterus produced cell death inhibitory factors, such as BCL-2, as early as embryonic stage.The expression of BCL-2 in adult endometrium is mainly inInterstitial cellMedium, and with periodic changes, it reaches the peak in the late stage of hyperplasia, decreases in the early stage of secretion, and disappears in the late stage of secretion and menstruation.Therefore, it is speculated that the disappearance of BCL-2 in late secretory phase and menstrual period is closely related to the death of endometrial cells and the occurrence of menstruation.
1. Epidermal growth factor and its receptor:epidermal growth factor (EGF)Mainly distributed inUterine cavityEpithelium andGlandular epitheliumas well asInterstitial cellMedium and presentedPeriodic change。Its physiological functions lie in: ① stimulating the proliferation of endometrial glandular epithelium and stroma, andSynergyTo differentiate the stroma; ②act oncell surfaceIt can rapidly stimulate the phosphorylation of arginine and promote the endometriumPGE2Release of.
2. Plateletsgrowth factorPlatelet growth factor mainly comes from endometrial stromal cells.It can stimulate the proliferation of interstitial cells or adjacent epithelial cells, so it hasautocrineandParacrineRole of.At the same time,PDGFEGF enhancedCell proliferationeffect.
endometritisAbout 10-15% of adult women are affected.The symptoms of this disease usually appear in the twenties and continue untilthe menopause。Most patients will be tested whether they have this disease between the ages of 25 and 35.Sometimes, whenLunar tideEndometritis is formed when it begins to stabilize.Infection that endangers endometritissterilityThe proportion of infertile women accounted for 9.4%.The causes of infertility caused by this disease include:
After the sperm enters the uterine cavity,Bacterial toxin、white blood cellInflammatory factors such as phagocytosis cause sperm death or decrease in motility, making sperm enterFallopian tubeThe number of children is reduced, thus affecting fertility.
be fertilizedZygoteIt is not easy to implant in inflammatory endometrium, or the implantation barrier caused by anti endometrium causes infertility.
The implantation of fertilized eggs is unstable, which is extremely easy to miscarry, leading to infertility.
clinical manifestation
1、Leukorrhea: Due to increased secretion of endometrial glands.It is generally thin water sample, light yellow, sometimesBloody leucorrhea。
3、dysmenorrhea: Most occur inNulliparousHowever, there are few patients with severe dysmenorrhea, which may be caused by excessive thickening of endometrium, obstruction of normal degeneration and necrosis of tissues, and stimulation of excessive spastic contraction of uterus.
4、Menorrhagia: The menstrual period is still regular, but the volume of menstruation is doubled, and the bleeding period is also significantly prolonged. Only a few patients suffer from massive bleedinganemia, which may be caused by intimal thickening and inflammatory hyperemia.
5. Old ageChronic endometritisSymptoms: often combinedAtrophic vaginitisThe occurrence of purulent leucorrhea, which often contains a small amount of blood, is often mistaken for malignant uterine disease.When pyometra occurs, the secretion has a purulent odor, and the patient will not feel the abdomenDull painExternal, systemicinflammatory reaction Symptoms, but with or without symptoms.
Diagnosis and diagnosis
withUterine cavityWhen the probe probes into the uterine cavity, if anyPurulent fluidThe diagnosis can be established after outflow, but the uterine cavity tissue should be taken gently at the same time to understand whether there isMalignant tumorExists.Sometimes due toCervical canalThere are many scars and the cervical tube is bent, so the probe is not easy to insert, so patient operation is required.Once the diagnosis is established, the cervix will be dilated, and pus can flow out smoothly.If the drainage is not satisfactory, a rubber tube can be placed in the cervical tube for drainage to prevent the cervical tube from blocking again in a short time and affecting the discharge of pus.
Influence of gestation
1. Endometritis can cause endometrial congestion, edema, and a large number of inflammatory exudates, which is not conducive to the ascending of sperm and the implantation and development of pregnant eggs;
2. Inflammatory factors, such as bacterial toxins and leukocyte phagocytosis, can cause sperm death or reduce motility, thus greatly affecting fertility;
3. The fertilized egg is not easy to be implanted in the inflammatory endometrium, orAnti endometrial antibodyIt may cause implantation obstacle or unstable implantation of the fertilized egg, which is very easy to miscarry.
Thickening
reason
IEndogenous estrogen
⑴Anovulation: Adolescent girls, perimenopausal womenHypothalamus pituitary ovary axisA link ofPolycystic ovary syndromeAnd so on, can have anovulation, so that the endometriumSustainabilitysufferestrogenAction, no progesterone resistance, lack of periodicitySecretory phaseIt is in a state of proliferation for a long time.Endometrium under 40 years oldAtypical hyperplasiaIn patients, more than 80% of the endometrium had no secretory phase except for focal atypical hyperplasia;70% of the basic body temperature was monophasic.So most patientsAnovulation。
⑶ EndocrineFunctional tumor: Endocrine functiontumourIt is a rare tumor, but in the research statistics, 7.5% of them are endocrine functional tumors.Pituitary glandThe gonadotropic function of,Granulosa cell tumor of ovaryIt is also a tumor that continuously secretes estrogen.
⑴ Estrogen replacement therapy (ERT):PerimenopauseOr postmenopausal, due to estrogen deficiencyClimacteric syndrome, and there may beosteoporosis、Abnormal lipid metabolism、cardiovascularChange, evenBrain cellChange of activities, etc.Therefore, ERT is gradually widely used and has achieved good results.However, estrogen alone in ERT will stimulateEndometrial hyperplasia。One year's use of estrogen alone can lead to 20% of women's endometrial hyperplasia (Woodruff 1994). The use of ERT often lasts for years, even all their lives. If progesterone is not used at the same time, there will be serious endometrial hyperplasia, or evenEndometrial carcinomaOccurrence of.
⑵TamoxifenApplication of tamoxifen: tamoxifen TAMAntiestrogenIt is used in the late postmenopausal periodmammary cancerpatient.Under the condition of low estrogen, TAM has a weak estrogen like effect, so taking TAM for a long time can also cause endometrial hyperplasia.
treatment
endometriumAtypical hyperplasiaThe first step is to make a clear diagnosis and find out the cause of atypical hyperplasia, whether there is polycystic ovary, ovarian functional tumor or other endocrineDysfunctionEtc.Any of the aboveShould beTargeted treatment.At the same time, atypical hyperplasia of endometrium can startSymptomatic treatment, usingmedicationorsurgical treatment。The choice of these two treatment schemes should be based on age, the type of endometrial hyperplasia, and the requirements for fertility.
Endometrial thickeningAbnormality can lead to infertility,The endometrium is the receptorEndogenous hormoneIf the excessive thickening is caused by the change of hormone level, it may not only affect menstruation, but also affect normal ovulation, and is not conducive to the implantation of fertilized eggs, leading tohabituationMiscarriage or infertility.It is recommended to have a vagina three days after menstruationB-mode ultrasonographyTo investigate the detailed thickness of endometrium.If the endometrium is too thick, it is very painful when menstruation comes, not to mention that the fertilized egg is not easy to implant.
Endometriosis
Main symptoms
Generally speaking, women's endometrium covers the uterusCoelomIf the endometrium grows in other parts of the body due to certain factors, it is calledEndometriosis。This ectopic endometriumHistologyThere are not only endometrial glands, but also endometrial stroma around the upper part;The function of endometriosis varies significantly with the estrogen level, that ismenstruationIt changes periodically, but only partially affected by pregnancy hormone, which can produce a small amount of "menstruation" and cause various clinical phenomena.
If the patient becomes pregnant, the ectopic endometrium may have decidual changes.Although the ectopic endometrium grows in other tissues or organs, it is different fromMalignant tumorInfiltration.EndometriosisMorbidfastigiumAt 30-40 years old.The reality of endometriosisincidence rateIt is far more than clinical findings.If the patient is suffering from other gynecological diseasesExploratory laparotomyTime and to resectedAdnexa uteriDetailed sample makingPathological examinationIt can be found that about 20-25% of patients have ectopic endometrium.
clinical examination
1. Method of B-ultrasound: B-ultrasound is a common itemGynecological examination, through B-ultrasound endomembrane likecystIt can be seen from the acoustic image thatGranularThe small echo is as thick as cystic fluid.Experts pointed out that,B-ultrasonic inspectionThere are certain limitations, and this method is usually not recommended.
2、laparoscopeLaparoscopy is an effective method to diagnose endometriosis, and has certain therapeutic effect on endometriosis.Laparoscopic examination showed that the freshest implant was yellow vesicles;
3、X-rayExamination: X-ray examination is a commonly used examination methodPelvic inflatable radiographyLateral film shows more obvious adhesion mass of fallopian tube and ovary, which can be more clearly shown on inflation radiography or inflation radiography.
harm
1. Causesterility: The infertility caused by endometriosis has accounted for about 50% of female infertility, which is an important reason for female infertility, mainly because endometriosis will lead toPelvic adhesion、Obstruction of fallopian tubeAnd affect hormone function andimmunityTo cause infertility.
2、ectopic pregnancy: Endometriosis is easy to causePelvic adhesion, causing obstacles to the operation of the fallopian tube, resulting in the failure of the fertilized egg to be successfully sent into the uterine cavity for local plantingEctopic pregnancy。
4、ovarian tumor : The main place of endometriosis is the ovary, so every time a woman comes to menstruation, menstrual blood will accumulate in the ovary, leading to the formation of tumors. Not only that, if not treated in time, the blood in the tumor will accumulate more and more, and will deteriorate,red blood cellDamagedChocolate cyst。
therapeutic method
1、 Modern medical medication
①、Pseudopregnancy therapy: Use large doses of estrogen and progesteroneSteroidal drug causePseudopregnancyTreatment.The ectopic endometrium will be transformed into decidua, and then the decidua will be necrotic, absorbed and subsided.Kistner introduces the daily use ofNorethisterone5mg、Ethinylestradiol0.075mg treatment, good effect,Adverse reactionsLight.continuedAdministrationFrom June to December, the symptoms were significantly relieved, and the focus was narrowed or disappeared.Some patients may relapse after drug withdrawal.After treatment, the ovulation function can be restored in a short time.Post treatmentPregnancy rateIt is 30% - 43%, applicable to young patients with mild illness who require fertility, and patients with recurrent symptoms after surgery.
②、Pseudomenopause therapy: Synthetic 17-α-acetyleneTestosteronederivativeDanazol。The drug is weakandrogenActionGonadotropinThe release ofSteroid hormoneIt can reduce the estrogen in the body and inhibit the growth of endometriumamenorrhoea, but itsFSHandLHIt belongs to low value rather than high value, so it is also called pseudomenopause therapy.For Domoski reportThis medicineThe pregnancy rate after treatment was 72%. During the treatment, the symptoms were alleviated by 100%, and the physical signs were improved by 85%.15% to 30% recurred after drug withdrawal.The commonly used dose is 400-800mg per day, which is taken orally for 2-4 times, starting from the 5th day of menstruation, and the treatment lasts for 3-6 months.Ovulation can resume within a few weeks after drug withdrawal.The adverse reactions areHot flushes, sweatingacne, edema, weight gain, etc.Others have elevated SGPT, which is related to theChemical structureCausebileIt is caused by depression and can recover after stopping the medicine.Danazol treatmentEndometriosisThe curative effect is good, and the adverse reaction is mild, if combinedfibroidHowever, it is expensive and difficult to be widely used.
③ Drug induced ovariectomy: long-term effectGonadotropin releasing hormone analogueTreatment (long-term effectGnRH-α)。Drug actionIt can significantly inhibit the level of FSH and reduce the secretion of ovarian estrogen.Meldrum reported on the 5th day of menstruation with GnRH-αone hundredμg,subcutaneous injection, once a day x 28 days, blood test after one month of treatmentEstradiolIt was significantly reduced, similar to that of ovariectomized patients.The symptoms of the patients improved during treatment, and they resumed menstruation after stopping treatment for a week. Long term treatment is similar to ovariectomy, which is a definite method for the treatment of endometriosis.
2、 Modern medical surgery
① Conservative surgery: it is applicable to young patients who require fertility.The scope of surgery includes separation of pelvic adhesionElectrocauteryOr removal of pelvic lesions, uterine suspension, ovaryEndometriotic cystStripping, etc.If the operation fails to completely remove the focus, medication should be used for 3-4 months after the operation.The pregnancy rate after conservative surgery was 40% - 60%.
② Semi conservative surgery: for those who do not have fertility requirements, or younger people whose condition requires hysterectomy, semi conservative surgery with ovarian preservation should be performed as far as possible, and normal ovarian tissue on one or both sides should be preserved to avoid postoperative occurrenceMenopausal syndrome。
③、radical operation: The patient is in a serious condition, and the older one is feasibleHysterectomy and adnexectomyTo achieve the goal of radical cure.If the adhesion is serious and it is difficult to remove the uterus, it is feasibleSubtotal hysterectomyOr only bilateral ovaries were removed.

Too thin
The thickness of endometrium will change at different times of the female menstrual cycle, mainly due to the influence ofhormoneCaused by the influence of secretion.If it is caused by abortion and other factorsThin endometriumIt will have a great impact on women's pregnancy.
Women's emotions have a great impact on the endometrium. Long term tension and worry often lead toEndocrine disorderTo affect the thickness of the inner membrane.
The intima is divided into three layers. The top layer is peeled off every month. The middle layer and the bottom layer are not peeled off. If the middle layer is damaged, the impact is not significant. If the bottom layer is damaged, the consequences will be serious.
Endometrium grows under the stimulation of estrogen. Most of them use estrogen to improve the thickness of endometrium. However, western medicine estrogen has certain effects on endocrineInterference effect。If drug supplementation is needed, it can be improved through traditional Chinese medicine therapy. Traditional Chinese medicine adopts compound drugs, with relatively few side effects.
2. Relax
Relaxing is actually the most effective way to regulate endocrine, which is very important.Under the influence of good mood, women can not only have more health, but also exude charming charm. Don't ignore this.
In addition, the thickness of endometriumperiod of ovulationThere are changes at different times from menstruation.It keeps getting thicker from very thin, then falls off during menstruation, and then gets thicker from very thin.If excluded as congenitalThin endometriumIf so, it should be endocrine disorder. Doctors can increase estrogen to thicken it, or drink traditional Chinese medicine to recuperate it.If menstruation has been abnormal, abnormal ovulation will also lead to thin endometrium. Pregnancy is not easy, but the opportunity is still great.
