Abstract
BACKGROUND When ovarian endometrioma coexist with adenomyosis, the risk of postoperative recurrence increased. How is the effect of levonorgestrel-releasing intrauterine system (LNG-IUS) on symptomatic recurrence for those patients was unknown. METHODS This study retrospectively analyzed 119 women with coexistent endometrioma and diffuse adenomyosis who received laparoscopic excision of pelvic endometriosis from January 2009 to April 2013. Women were categorized into two groups: intervention group with LNG-IUS and control group with expectant observation after surgery. Data were compared in terms of preoperative history, laboratory and intraoperative findings, and clinical outcomes during follow-up, including pain regression, changes in uterine volume and recurrence. RESULTS During a median 79 months (range, 6-107) of follow-up, patients with LNG-IUS experienced a significantly lower symptomatic recurrence of either ovarian endometrioma or dysmenorrhea (11.1% vs. 31.1%, p = 0.013), compared with women under expectant observation by Kaplan-Meier survival analysis (χ2 = 5.448, p = 0.020) and Cox univariate assessment (hazard ratio of 0.336, 95% confidence interval 0.128-0.885, p = 0.027). Patients treated with LNG-IUS demonstrated a more prominent reduction in uterine volume (-14.1 ± 20.9 vs. 8.7 ± 48.8, p = 0.003) and higher percentage of complete pain remission (95.6% vs. 86.5%). For multivariate analysis, use of LNG-IUS (aHR 0.159, 95%CI 0.033-0.760, p = 0.021) and severity of dysmenorrhea (aHR 4.238, 95%CI 1.191-15.082, p = 0.026) were two independent factors associated with overall recurrence. CONCLUSION Postoperative insertion of LNG-IUS may prevent recurrence in symptomatic women with comorbidity of ovarian endometrioma and diffuse adenomyosis.

Abstract
Objective: To investigate the difference of clinical features and outcomes between EM patients with and without AM after following up for at least 6 years after surgery. Methods: We retrospectively analyzed 358 EM patients who had a minimum of 6 years follow-up after laparoscopic cystectomy, which was performed by one single doctor at Peking Union Medical College Hospital from January 2009 to April 2013. All women were divided into AM group and non-AM group and analysis was performed in preoperative characteristics, surgical findings and postoperative outcomes during follow-up. Results: A total of 358 EM patients were recruited, of which 142 (39.7%) were in the AM group and the rest 216 (60.3%) in the non-AM group. Between the two group, the mean age was 34.6 vs. 32.2 years (P < 0.001). The mean operating time in the AM and non-AM group was 73.2 vs. 61.9 min (P < 0.001). According to the revised AFS classification, the mean score of the two group were 60.3 vs. 45.5 (P < 0.001). At the end of the follow-up, though the AM group was with higher rate of disease relapse, yet no significant difference was found between the two groups in statistical comparison (34/142 [23.9%] vs. 34/216 [15.7%], P = 0.053). With a minimum follow-up of 6 years after laparoscopic cystectomy, failed and successful pregnancy were seen in 107/142(75.4%) and 35/142 (24.6%) patients in the AM group vs. 114/216(52.8%) and 102/216 (47.2%) patients in the non-AM group (P < 0.05). As for the successfully pregnant patients, live births, including spontaneous pregnancy and IVF-ET, were seen in 34/35 (97.1) vs. 99/102 (97.1) patients between AM and non-AM groups, while others ended in spontaneous abortion. No significant associations were found between the two groups in infertility, leiomyoma presence, the size of ovarian endometrioma, type of deep infiltrating endometriosis (DIE) or type of recurrence (P > 0.05). Conclusion: Compared with non-AM group, EM patients with concurrent AM may have higher age, longer mean operating time and higher mean AFS score. In terms of fertility outcomes, patients in the AM group were with lower likelihood of pregnancy after surgery during the long-time follow-up.

Abstract
Endometriosis is a prevalent chronic disease that affects approximately 6% to 10% of reproductive-aged women. Although numerous researchers have endeavored to explore the etiology of endometriosis over a century, its etiology still remains an enigma. The exploration of pathophysiologic mechanism and novel therapy for endometriosis depends on ideal endometriotic models. In the previous decade, various endometriotic models have been established; therefore, we made a conclusion for available information on these models. This review summarized the common experimental models used in endometriotic studies, including their origins, characteristics, applications, and limitations. Endometriotic models played an important role in studying etiologies and novel treatments of endometriosis during the last decades. Among them, animal models and endometriotic cell lines were viewed as most common studying tools to explore the intrinsic entities of endometriosis. In addition, endometrial organoid also emerged and was regarded as an ideal studying tool for endometriosis research. Different research models collectively complement each other to advance the endometriosis research. The successful establishment of endometrial organoids means that organoids are expected to become an ideal model for studying endometriosis in the future.

Abstract
STUDY QUESTION What are the oncofertility outcomes of young women (≤40 years old) with bilateral serous borderline ovarian tumors (SBOTs) after fertility-sparing surgery? SUMMARY ANSWER Fertility preservation with the bilateral ovarian cystectomy procedure is feasible for bilateral SBOTs, with an acceptable oncological outcome and worthwhile pregnancy rates. WHAT IS KNOWN ALREADY Fertility-sparing approaches are becoming the standard management of young patients with unilateral SBOTs and other borderline histological subtypes. However, there is a paucity of evidence to dictate the best management in bilateral SBOTs. STUDY DESIGN, SIZE, DURATION This was a retrospective observational study performed at the Peking Union Medical College Hospital in Beijing, China, between January 1999 and January 2019. PARTICIPANTS/MATERIALS, SETTING, METHODS Ninety-four women (≤40 years old) with pathologically confirmed bilateral SBOTs were included. Following preoperative counseling, patients self-selected into one of three treatment modalities: bilateral ovarian cystectomy (n = 48), unilateral adnexectomy plus contralateral cystectomy (UAC; n = 31), and radical surgery (n = 15). Univariate and multivariate analyses were used to determine the clinical and pathological features associated with disease-free survival and reproductive outcomes. MAIN RESULTS AND THE ROLE OF CHANCE During the median follow-up of 64 months (range, 4-243 months), 61 patients (65%) developed relapse, including 3 (20%) in the radical group, 26 (84%) in the UAC group and 32 (67%) in the bilateral cystectomy group. In the multivariate analyses, preoperative CA-125>300 U/mL, fertility preservation and micropapillary pattern were independently associated with adverse disease-free survival (P = 0.001, 0.03 and 0.026, respectively). Fourteen patients (15%) experienced invasive recurrence, and three (3%) died of progressive disease. The micropapillary pattern was significantly associated with invasive evolution risk (P = 0.006). Of the 49 patients who attempted to conceive, 23 (47%) achieved 27 pregnancies (24 spontaneous and three after IVF-ET), resulting in 19 live births. There was no significant difference in disease-free survival (P = 0.13) or pregnancy rate (41 vs. 50%, P = 0.56) between the UAC and bilateral procedures. LIMITATIONS, REASONS FOR CAUTION As a retrospective study conducted in a referral center, inherent biases exist. The nonrandom allocation to treatment groups and relatively small number of patients attempt to conceive might limit the statistical power of our findings. Only 41 patients (43.6%) received complete staging during their initial surgeries, so an underestimation bias in terms of the FIGO stage and extraovarian implants might have occurred. WIDER IMPLICATIONS OF THE FINDINGS The ultraconservative bilateral ovarian cystectomy procedure should be proposed in bilateral SBOTs when technically feasible. Invasive evolution occurs frequently in these women, and intense follow-up and oncofertility counseling are warranted, especially for those with micropapillary patterns. STUDY FUNDING/COMPETING INTEREST(S) No external funding was used for this study. There are no conflicts of interest to declare. TRIAL REGISTRATION NUMBER N/A.

Abstract
OBJECTIVE Thoracic endometriosis syndrome (TES) is a rare disease in which a functioning endometrial tissue is observed in the pleura, lung, parenchyma, airways, and/or diaphragm. The optimal management of this disease remains a matter of debate. We aimed to report TES cases and their effective hormonal treatment and management. METHODS In this retrospective study, women presented as catamenial hemoptysis (CH) diagnosed with thoracic endometriosis were included. The main outcome of measure was cessation or recurrence of the clinical manifestations of thoracic endometriosis. RESULTS The mean onset age of the 14 patients was 30.21 ± 5.40 years. CH was characteristic symptom of these patients. All patients underwent chest computed tomography (CT) scan during menstruation and 2 or 3 weeks after menstruation, which showed the obvious shrinking or disappearance of the lesions. All of the patients were given Gonadotropin releasing hormone agonists (GnRHa) for 3 to 6 months, eleven of them were administered with combined oral contraceptives (COC) cyclically after GnRHa. The median follow-up duration was 24 months. Hemoptysis recurrence was observed in one patient. CONCLUSIONS CH is a rare clinical entity of thoracic endometriosis, the change of CT images during and after menstruation or the response to GnRHa were helpful for accurate diagnosis. Hormonal treatment with GnRHa followed by COCs cyclically could be employed for efficient management of thoracic endometriosis.

Abstract
Background Inguinal endometriosis (IEM) is a rare extra pelvic endometriosis. Here, we study the clinical characteristics, management strategies, and long-term gynecological outcomes of IEM patients at Beijing Chaoyang Hospital. Case presentation Three patients presented with a total of four lesions (one on the left side, one on the right side, and one bilaterally). The diameters of the four lesions were 2 cm, 2 cm, 3.5 cm and 1.5 cm, respectively. Two patients were admitted with inguinal hernias. Two patients were admitted with endometrioses—one with ovarian endometriosis and one with pelvic endometriosis. The hernia sac was repaired concomitantly via excision of the round ligament in two patients. One patient underwent a concomitant laparoscopy for gynecologic evaluations, including an ablation to the peritoneal endometriosis, and resection of the left uterosacral ligament endometriosis and pelvic adhesiolysis. All lesions were located on the extraperitoneal portion of the round ligament and were diagnosed histologically. No recurrence was observed in the inguinal region. All patients diagnosed with adenomyosis were treated with medication alone without any complaints. Conclusions Inguinal endometriosis can occur simultaneously with pelvic endometriosis. In most cases, a concomitant hernia sac appears together with groin endometriosis. Clinical management should be individualized and performed in tandem with general practitioners and obstetrics & gynecology experts. Pelvic disease, in particular, should be followed-up by a gynecologist.

Abstract
PURPOSE Here, we compared endometrioma recurrence rates in patients who have undergone a laparoscopic cystectomy and treated with a gonadotropin-releasing hormone agonist (GnRHa) alone or a GnRHa combined with a levonogestrel intrauterine system (LND-IUS). METHODS We enrolled endometrioma patients who underwent laparoscopic cyst enucleation and divided them into two groups according to postoperative management: GnRHa alone and GnRHa in combination with LND-IUS. We compared preoperative history, perioperative parameters, postoperative endometrioma recurrence, and symptoms between these two groups. RESULTS A total of 320 patients were included in the final analysis. With a median 84.6 months of follow-up, we detected significant differences between the two groups with respect to age at surgery (31.6 ± 4.8 vs. 37.6 ± 4.2 years, χ2 = 1.978, p < 0.001), gravida (0 vs. 2, χ2 = 4.391, p < 0.001), parity (0 vs. 1, χ2 = 0.035, p < 0.001), body mass index (21.0 ± 2.5 vs. 21.9 ± 2.4, χ2 = 0.0096, p = 0.009), r-AFS score (48 vs. 64, χ2 = 4.888, p = 0.001), and operation time (60 vs. 75 min, χ2 = 9.119, p = 0.003). Patients treated with both GnRHa and LND-IUS achieved significantly less endometrioma recurrence (23.6 vs. 11.5%, χ2 = 5.202, p = 0.023) and higher rates of pain remission (92.1 vs. 100%, χ2 = 6.511, p = 0.011), while those with GnRHa alone suffered more recurrent and painful symptoms (χ2 = 9.280, p = 0.026). Multivariate analysis using a Cox regression demonstrated that combined GnRHa and LNG-IUS treatment correlated with a decreased endometrioma recurrence rate after laparoscopic cystectomy (RR 0.369, 95% CI 0.182-0.749, p = 0.006). CONCLUSIONS Combination treatment of GnRHa and LNG-IUS exhibited superior pain relief and recurrence prevention among endometrioma patients after fertility-sparing surgery. Thus, combination treatment is a preferable long-term option for patients without intent for pregnancy in the near future.

Abstract
Objective: To discuss the imaging, clinical features and management of diffuse uterine leiomyomatosis (DUL). Methods: Six cases of DUL confirmed in Peking Union Medical College Hospital from August 2009 to September 2019 were reviewed on their image and clinical data. Retrospective analysis was conducted on their perioperative and postoperative follow-up data. Results: The average age of the first diagnosis of DUL was (27±3) years old. All of the patients complained menorrhagia and three patients suffered moderate to severe anemia. Three patients were diagnosed infertility. Pelvic ultrasound and MRI showed symmetrical enlarged uterus with complete replacement of the myometrium by innumerable, confluent leiomyomas.Four patients were treated with GnRH-a before operation to reduce the volume of myoma and correct anemia. Among the six patients, five had undergone myomectomy because of DUL before visiting Peking Union Medical College Hospital. Three patients underwent open myomectomy. The number of resected myoma was 188-300 and the bleeding volume was 1 200-2 500 ml. Two of them suffered recurrence at 51 and 40 months after operation. One received sirolimus for 20 months without recurrence until now. Other three patients underwent hysterectomy. One patient underwent partial small bowel resection and partial omentum resection because of severe pelvic adhesion during hysterectomy, and the blood loss was 2 000 ml. Conclusions: Pelvic imaging especially MRI is helpful for early recognition and preoperative evaluation for DUL. Fertility preservation is a great challenge for DUL patients. The risk of recurrence after myomectomy is high. Hysterectomy is the last choice to completely cure DUL at present.

Abstract
An ideal research model plays a vital role in studying the pathogenesis of a disease. At present, the most widely used endometrial disease models are cell lines and animal models. As a novel studying model, organoids have already been applied for the study of various diseases, such as disorders related to the liver, small intestine, colon, and pancreas, and have been extended to the endometrium. After a long period of exploration by predecessors, endometrial organoids (EOs) technology has gradually matured and maintained genetic and phenotypic stability after long-term expansion. Compared with cell lines and animal models, EOs have high stability and patient specificity. These not only effectively and veritably reflects the pathophysiology of a disease, but also can be used in preclinical drug screening, combined with patient derived xenografts (PDXs). Indeed, there are still many limitations for EOs. For example, the co-culture system of EOs with stromal cells, immune cell, or vascular cells is not mature, and endometrial cancer organoids have a lower success rate, which should be improved in the future. The investigators predict that EOs will play a significant role in the study of endometrium-related diseases.

Abstract
Purpose Our study aims to investigate the distribution of pain symptoms and the association between pain symptoms and clinical parameters in patients with adenomyosis. Patients and methods The clinical and pathological data of 291 patients diagnosed with adenomyosis in the Obstetrics and Gynecology Department of Peking Union Medical College Hospital from March 2012 to September 2015 were collected, and analyzed in regard to the pain symptoms. Results The median age at disease onset was 34 years. 71.8% of the patients had pain symptoms (pain group) and 28.2% had no pain symptoms (painless group). Patients with symptoms accompanied by dysmenorrhea accounted for 68%, among which 30.3% were mild, 36.9% were moderate, and 32.8% severe, while 56.1% presented with progressive pain. Through comparison, significant differences were identified between the pain and painless groups with regard to age at diagnosis (P=0.009), age at onset of disease (P=0.008), and level of pre-surgical CA125 (P<0.001), as well as proportion of patients with rectal irritation (P=0.008), elevated CA125 level (P<0.001), thickened myometrial layer (P<0.001) and concurrent endometriosis (P=0.001). In the multivariable analysis, an elevated level of pre-surgical CA125 (P<0.001) and thickened posterior myometrial layer (P=0.023) were both independent risk factors for the morbidity of pain symptoms. Similar results except for the difference in rectal irritation were noticed when we made further comparison between the dysmenorrhea and non-dysmenorrhea groups in adenomyosis patients. Conclusion Our research analyzes the clinical features related to pain symptoms in patients with adenomyosis, which may provide clues for the possible presurgical diagnosis of adenomyosis, as well as references for pain management of adenomyosis.

Abstract
Objective To explore the risk factors for the recurrence of endometrioma and the risk factors for the recurrence of endometriosis-related pain after long-term follow-up. Methods This study retrospectively analyzed 358 women with endometriomas who had a minimum of 5-years follow up after laparoscopic endometrioma excision, which was performed at Peking Union Medical College Hospital from January 2009 to April 2013. All women were divided into recurrence group and nonrecurrence group. Analysis was performed with regard to preoperative history, laboratory analysis, findings during surgery, and symptoms during follow-up, including improvement and recurrence. Results The cumulative incidence rates of recurrence from 5 to 10 years after surgery were 15.4, 16.8, 19.3, 22.5, 22.5, and 22.5%, respectively. Significant differences were found between two groups in terms of age at surgery (RR: 0.764, 95% CI: 0.615–0.949, p = 0.015), duration of dysmenorrhea (RR: 1.120, 95% CI: 1.054–1.190, p < 0.001), presence of adenomyosis (RR: 1.629, 95% CI: 1.008–2.630, p = 0.046), CA125 level (RR: 1.856, 95% CI: 1.072–3.214, p = 0.021) and severity of dysmenorrhea. The severity of dysmenorrhea (RR: 1.711, 95% CI: 1.175–2.493, p = 0.005) and postoperative pregnancy (RR: 0.649, 95% CI: 0.460–0.914, p = 0.013) were significantly correlated with endometrioma recurrence in the multivariate analysis. No significant associations were found between the recurrence rate and gravida, parity, body mass index, infertility, leiomyoma presence, the size of ovarian endometrioma, the presence of deep infiltrating endometriosis, disease stage or postoperative medication. Conclusions The severity of dysmenorrhea and postoperative pregnancy were independent risk factors for the recurrence of ovarian endometriomas after surgery during the long-time follow up.

Abstract
Objective: To understand the perceptions, attitudes and treatment selection of Chinese surgeons on the "watch and wait" strategy for rectal cancer patients after achieving a clinical complete response (cCR) following neoadjuvant chemoradiotherapy (nCRT). Methods: A cross-sectional survey was used in this study. Selection of subjects: (1) Domestic public grade III A (provincial and prefecture-level) oncology hospitals or general hospitals possessing the radiotherapy department and the diagnosis and treatment qualifications for colorectal cancer. (2) Surgeons of deputy chief physician or above. Using the "Questionnaire Star" online survey platform to create a questionnaire about cognition, attitude and treatment choice of the "watch and wait" strategy after cCR following nCRT for rectal cancer. The questionnaire contained 32 questions, such as the basic information of doctor, the current status of rectal cancer surgery, the management of pathological complete remission (ypCR) after nCRT for rectal cancer, the selection of examination items for diagnosis of cCR, the selection of suitable people undergoing "watch and wait" approach, the nCRT mode for promotion of cCR, the choice of evaluation time point, the willingness to perform "watch and wait" approach and the treatment choice, and the risk and monitoring of "watch and wait" approach. A total of 116 questionnaires were sent to the respondents via WeChat between January 31 and February 19, 2019. Statistical analysis was performed using Fisher's exact test for categorical variables. Results: Forty-eight hospitals including 116 surgeons meeting criteria were enrolled, of whom 77 surgeons filled the questionnaire with a response rate of 66.4%. "Watch and wait" strategy was carried out in 76.6% (59/77) of surgeons. Seventy surgeons (90.9%) were aware of the ypCR rate of rectal cancer after preoperative nCRT and 49 surgeons (63.6%) knew the 3-year disease-free survival of patients with ypCR in their own hospitals. Fifty-five surgeons (71.4%) believed that patients with ypCR undergoing radical surgery met the treatment criteria and were not over-treated. Three most necessary examinations in diagnosing cCR were colonoscopy (96.1%, 74/77), digital rectal examination (DRE) (90.9%,70/77) and DWI-MRI (83.1%, 64/77). Responders preferred to consider a "watch and wait" strategy for patients with baseline characteristics as mrN0 (77.9%, 60/77), mrT2 (68.8%, 53/77) and well-differentiated adenocarcinoma (68.8%, 53/77). Sixty-six surgeons (85.7%) believed that long-term chemoradiotherapy (LCRT) with combination or without combination of induction and/or consolidation of the CapeOX regimen (capecitabine + oxaliplatin) should be the first choice as a neoadjuvant therapy to achieve cCR. Forty-one surgeons (53.2%) believed that a reasonable interval of judging cCR after nCRT should be ≥ 8 weeks. Forty-four surgeons (57.1%) routinely, or in most cases, informed patient the possibility of cCR and proposed to "watch and wait" strategy in the initial diagnosis of patients with non-metastatic rectal cancer. Thirteen surgeons (16.9%) would take the "watch and wait" strategy as the first choice after the patient having cCR. Fifty-two surgeons (67.5%) would be affected by the surgical method, that was to say, "watch and wait" approach would only be recommended to those patients who would achieve cCR and could not preserve the anus or underwent difficult anus-preservation surgery. Sixteen surgeons (20.8%) demonstrated that "watch and wait" strategy would not be recommended to patients with cCR regardless of whether the surgical procedure involved anal sphincter. Eleven surgeons (14.3%) believed that the main risk of "watch and wait" approach came from distant metastasis rather than local recurrence or regrowth. Twenty-nine of surgeons (37.7%) did not understand the difference between "local recurrence" and "local regrowth" during the period of "watch and wait". Twenty-six surgeons (33.8%) thought that the monitoring interval for the first 3 years of "watch and wait" strategy was 3 months, and the follow-up monitoring interval could be 6 months to 5 years. Surgeons from cancer specialist hospitals had higher approval rate, notification rate, and referral rate of "watch and wait" strategy than those from general hospitals. Thirty-one surgeons (42.5%) considered that the difficulty and concern of carrying out "watch and wait" approach in the future was the disease progress leading to medical disputes. Twenty-six surgeons (35.6%) demonstrated that their concern was lack of uniform evaluation standard for cCR. Conclusions: Chinese surgeons seem to have inadequate knowledge of non-operative management for rectal cancer patients achieving cCR after nCRT and show relatively conservative attitudes toward the strategy. Chinese consensus needs to be formed to guide the non-operative management in selected patients. Chinese Watch & Wait Database (CWWD) is also needed to establish and provide more evidence for the use of alternative procedure after a cCR following nCRT.

Abstract
Background Because of the rarity of endometrioid borderline ovarian tumours (EBOTs), there is a paucity of data concerning the natural history and prognosis of this condition. Thus, the objective of our study was to establish the feasibility of fertility preservation in young women with EBOTs, as well as their oncological and reproductive outcomes. Methods Consecutive patients with EBOTs, treated at a tertiary referral centre during a span of 22 years, were retrospectively analysed. Recurrence-free interval, as well as its association with the type of surgery and with other clinical and pathological features, was assessed using the Kaplan-Meier and Cox proportional hazards methods. Results Of the 59 patients studied, the median follow-up time was 30 months (range, 6–177 months). Nine (15.3%) patients developed 13 recurrences 6–137 months after the initial surgeries, including three patients (5.1%; n = 3/59) who developed six invasive recurrences 8, 18 and 68 months after their initial surgeries. Conservative surgery showed a tendency towards a high recurrence rate (17.2% versus 13.3%); however, this difference was not significant (p = 0.45). The 5-year recurrence-free survival rate was significantly higher in the oophorectomy group than in the cystectomy group (p = 0.001). Cox regression analysis showed that none of the variables assessed were associated with an increased hazard ratio for recurrence, except for a younger age at diagnosis (p = 0.021). Of 20 patients who attempted to conceive, three pregnancies among two patients (10.0%) resulted in two live births. Conclusions Conservative surgery with unilateral adnexectomy can be proposed for young women with EBOTs with fertility desire; however, the reproductive result is not satisfactory. In addition, careful evaluations of the endometria should be offered during the initial surgery and follow-up period. Trial registration Retrospectively registered.

Abstract
Background: When considering the issue of recurrence, perimenopausal women may have more dilemma during management comparing with young women, for example, whether to retain the uterus and ovary during surgery, whether it is necessary to add adjuvant medicine treatment after operation, and there is no evidence for reference about using of gonadotropin-releasing hormone agonist. This study aimed to study the risk factors for the recurrence of ovarian endometriosis (EM) in patients aged 45 and over. Methods: This is a retrospective nested case-control study. We reviewed the medical records of patients aged over 45 years who underwent surgical treatments for ovarian EM from 1994 to 2014, in Peking Union Medical College Hospital of Chinese Academy of Medical Sciences. By following up to January 2016, 45 patients were found to have relapses and regarded as the recurrence group. The patients with no recurrence during the same follow-up period were randomly selected by the ratio of 1:4 as the nonrecurrence group (180 patients in total). Stratified Cox regression was used to analyze the risk factors of the recurrence. Results: Univariate analysis showed that there was a significant difference in the postoperative treatment (the percentage of patients who received postoperative treatment in non-recurrence group and recurrence group, 23.9% vs. 40.0%, χ2 = 4.729, P = 0.030) and ovarian preservation (the percentage of patients who received surgery of ovarian preservation in non-recurrence group and recurrence group, 25.0 % vs. 44.4%, χ2 = 19.462, P < 0.001) between the nonrecurrence group and the recurrence group. There was no correlation between recurrence and the following factors including patient's age, menarche age, gravidity, parity, CA125 level, ovarian lesions, menopausal status, combined benign gynecological conditions (such as myoma and adenomyoma) and endometrial abnormalities, and surgical approach or surgical staging (all P > 0.05). Multivariate analysis indicated that whether to retain the ovary was the only independent risk factor of recurrence for patients aged 45 years and over with ovarian EM (odds ratio: 5.594, 95% confidence interval: 1.919–16.310, P = 0.002). Conclusion: Ovarian preservation might be the only independent risk factor of recurrence for patients aged 45 years and over with ovarian EM.

Abstract
Background Endometriosis is a challenging disease with symptoms such as dysmenorrhea and infertility. However, its etiology is still vague and there is still no effective markers or treatment. This study aimed to profile the circular RNAs (circRNAs) expressed in eutopic endometrium from patients with ovarian endometriosis and explore potential clues to the pathogenesis of endometriosis, providing an evidence for clinical diagnosis and treatment. Methods A total of 63 clinical samples, including control endometrium (n = 22) and eutopic endometrium (n = 41), were collected from Peking Union Medical College Hospital between May 1, 2016, and December 31, 2016. Of them, four samples in each group were used for circRNA microarray. Then, four upregulated circRNAs were screened out for quantitative real-time polymerase chain reaction (qRT-PCR) validation. After that, bioinformatics analysis was performed to predict miRNAs targeted by validated circRNAs and investigate the circRNA-miRNA-mRNA interactions. Results Among 88 differentially expressed circRNAs, 11 were upregulated and 77 were downregulated in eutopic endometrium of patients with endometriosis. qRT-PCR validation results for two upregulated circRNAs (circ_0004712 and circ_0002198) matched the microarray results. The area under the receiver operating characteristic curve of circ_0002198 for distinguishing ovarian endometriosis was 0.846 (95% confidence interval [CI]: 0.752-0.939; P < 0.001) while that of circ_0004712 was 0.704 (95% CI: 0.571-0.837; P = 0.008). On the basis of target prediction, we depicted the molecular interactions between the identified circRNAs and their dominant target miRNAs, as well as constructed a circRNA-miRNA-mRNA network. Conclusions This study provides evidence that circRNAs are differentially expressed between eutopic and normal endometrium, which suggests that circRNAs are candidate factors in the activation of endometriosis. circ_0002198 and circ_0004712 may be potential novel biomarkers for the diagnosis of ovarian endometriosis.

Abstract
Background Synchronous endometrial disorders have been poorly studied in women with endometrioid borderline ovarian tumors (EBOT). The aims of this study were to investigate the risk of endometrial disorders among women with EBOT and associated factors, as well as their oncological and fertility outcomes. Results This retrospective study included 33 women with EBOT. Their mean age was 41.9 years, and endometria were evaluated in 25 of these patients. The prevalence of synchronous endometrial disorders was 52.0% (n = 13/25) and this incidence was 41.4% (n = 46/111) after systematic analysis. Univariable analysis showed that EBOT patients who were younger, nulliparous, and had experienced abnormal vaginal bleeding were more likely to have synchronous endometrial disorders. The median follow-up was 54 months (range: 14-250 months), and three patients (10.3%) developed recurrences. No deaths due to EBOT were recorded. Among the nine nulliparous women treated conservatively who were attempting to conceive, only one (11.1%) pregnancy resulted in a live birth. Conclusions Synchronous endometrial disorders are common in women with EBOT, especially in those who are younger, nulliparous, and have experienced abnormal vaginal bleeding. Thus, endometrial sampling should be performed in women with EBOT undergoing conservative surgery, and a hysterectomy should be performed in cases requiring radical treatment.

Abstract
Objective: To investigate the diagnostic value of some antibodies in peritoneal fluid of patients with gastric cancer and malignant epithelioid mesothelioma in serous effusion. Methods: One hundred and eighty-two cases of serous effusion were collected at Jilin Cancer Hospital, from July 2012 to July 2016. The expression of GLUT1, CDX2, Villin, calretinin and WT1 was evaluated using SP immunocytochemical technique in peritoneal fluid samples collected from 98 patients with gastric cancer and 74 patients with reactive mesothelial cells. The expression of GLUT1, calretinin and WT1 was also evaluated in serous effusion from 10 patients with mesothelioma. Results: The sensitivity of GLUT1, CDX2 and Villin in adenocarcinoma cells was 91.8%(90/98), 68.4% (67/98) and 88.8%(87/98), respectively. The specificity was 95.9% (71/74), 100.0%(74/74) and 100.0% (74/74), respectively. The sensitivity of calretinin and WT1 for reactive mesothelium was 93.2% (69/74) and 79.7% (59/74), respectively. The specificity was 96.9% (95/98) and 100.0% (98/98), respectively. The sensitivity of GLUT1, calretinin and WT1 for mesothelioma was 9/10, 9/10 and 7/10. The reactivity of GLUT1, CDX2, Villin, calretinin and WT1 showed a significant difference (P<0.01) between adenocarcinoma cells and reactive mesothelium. The reactivity of GLUT1 showed a significant difference (P<0.01) between mesothelioma and reactive mesothelium. Conclusions: The optimal combination is a panel of GLUT1, CDX2, Villin, calretinin and WT1 for differential diagnosis between adenocarcinoma cells and reactive mesothelium in peritoneal fluid of patients with gastric cancer. Whereas GLUT1, calretinin and WT1 is the best for differential diagnosis between reactive mesothelium and mesothelioma in serous effusions.

Abstract
BACKGROUND To explore the risk factors of endometriosis-associated ovarian cancer (EAOC) in women with ovarian endometriosis (OEM) aged 45 years and above in China. METHODS This study reviewed the medical records of 1038 women in total who were aged 45 years and above, surgical-pathologically diagnosed with ovarian endometriosis, and were treated at Peking Union Medical College Hospital between December 1996 and December 2016. Histology evaluation was used to determine whether the ovarian endometriosis specimen was with (n = 30) or without (n = 1008) ovarian cancer. RESULTS 2.9% (30/1038) of women with the surgical-pathological diagnosis of ovarian endometriosis were found to have EAOC. Those patients with EAOC were prone to be in the postmenopausal status at the time of the diagnosis (OR 5.50, 95%CI 2.54-11.90, P < .001) and larger size of tumor (≥8 cm, OR 7.19, 95% CI 3.34-15.50, P < .001), and higher prevalence of coexisting with endometrial disorders (OR 4.11, 95%CI 1.73-9.73, P = .003). This study showed that patients of an older age when diagnosed with OEM, were at a higher risk of developing EAOC, respectively measuring of 1.7% (13/751) at 45-49 years, 5.6% (12/215) at 50-54 years, and 10.0%(5/50) at 55-59 years (P < 0.001). CONCLUSIONS This study showed that for women aged 45 years and above who were diagnosed with OEM, the independent risk factors of EAOC were menopausal status, tumor size of 8 cm or greater in diameter, and coexisting endometrial disorders. Therefore, intensive follow-ups or active interventions should be considered for them.

Abstract
Background: Adenomyosis is a gynecological disorder with symptoms most presenting as dysmenorrhea and heavy menstrual bleeding. However, the presence of lower urinary tract symptoms (LUTS) among women with adenomyosis remains unclear. This study was designed to determine the prevalence of LUTS and factors related to the severity of these symptoms in this population. Methods: From July 2016 to November 2016, a total of 298 untreated symptomatic adenomyosis patients and 280 age-matched controls were enrolled. Demographics, LUTS, pain symptoms, ultrasonographic uterine size, and serum CA125 level were recorded. LUTS were evaluated using the International Prostate Symptom Score (IPSS) questionnaire. Factors related to the severity of LUTS were detected using the logistic regression analysis presented as odds ratio (OR) and 95% confidence interval (CI). Results: Compared with the control group, patients with adenomyosis had a greater IPSS total (4 [2–8] vs. 2 [0–3], Z = –8.159, P < 0.001), IPSS storage (2 [1–4] vs. 1[0–2], Z = –7.361 P < 0.001), and IPSS voiding (2 [0–4] vs. 0 [0–1], Z = –7.194, P < 0.001). Of the patients with adenomyosis, 30.2% had moderate-to-severe lower urinary tract symptoms (IPSS ≥8). The most prevalent LUTS were daytime frequency (40.9%), followed by nocturia (24.8%), weak stream (24.2%), and incomplete emptying (23.5%). In study group, patients with an IPSS total score ≥8 had higher proportion of menorrhagia (51.1% vs. 30.8%, χ2 = 11.162 P = 0.025) and larger uterine volumes (183.3 [109.8–273.8] cm3 vs. 148.5 [96.4–262.7] cm3, Z = –1.441, P = 0.150) compared to patients with an IPSS total score <8. On multivariate logistic regression analysis, patients with menorrhagia were associated with an increased risk of an IPSS total score ≥8 (OR: 2.309, 95% CI: 1.310–4.070, P = 0.004), an IPSS storage subscore ≥4 (OR: 2.422, 95% CI: 1.395–4.206, P = 0.002), and an IPSS voiding subscore ≥5 (OR: 1.971, 95% CI: 1.176–3.302, P = 0.010). However, patients with uterine volume more than 180 cm3 had more than 2-fold risk of bearing IPSS total score ≥8 (OR: 2.437, 95% CI: 1.381–4.300, P = 0.002), IPSS storage subscore ≥4 (OR: 2.486, 95% CI: 1.433–4.314, P = 0.001), and IPSS voiding subscore ≥5 (OR: 2.700, 95% CI: 1.485–4.908, P = 0.001). Conclusions: Lower urinary tract symptoms are prevalent in patients with symptomatic adenomyosis and greatly affect patients’ quality of life. Menorrhagia and large uterine volume could be potential risk factors that increase the occurrence of moderate-to-severe LUTS.

Abstract
Obiective: To explore the risk factors of endometriosis-associated ovarian cancer (EAOC) in women with ovarian endometriosis aged 45 years and older in China. Methods: The medical records of total 1 038 women aged 45 years and older with a surgicopathological diagnosis of ovarian endometriosis treated at Peking Union Medical College Hospital from December 1994 to December 2014 were reviewed. Histology evaluation determined ovarian endometriosis with (n=30) or without (n=1 008) ovarian cancer. Results: (1) There were 30 (2.9%, 30/1 018) cases confirmed as having EAOC. Clear cell carcinoma (63.3%, 17/30) and endometrioid adenocarcinoma (23.3%, 7/30) were commonly observed subtypes and 70.0% of EAOC patients were at stage Ⅰ. (2) Compared women with ovarian endometriosis in the same age group, patients with EAOC were older (50.8 vs 48.5 years, P=0.002). There were more in postmenopausal status at diagnosis of EAOC (P<0.01). There were more found with a mass ≥8 cm (P<0.01). Women with EAOC had higher prevalence of coexisting endometrial disorders (P=0.003). No differences were found in preoperative CA(125) value and infertile or nulliparous women (P>0.05). Conclusions: For women with ovarian endometriosis aged 45 years and older, the subgroup of patients characterized by postmenopausal status and ovarian endometrioma (≥8 cm) have a higher risk of EAOC. Active intervention or intensive follow-up should be considered for this population group, especially for those concurrent with endometrial disorders.

Abstract
BACKGROUND Adenomyosis (AM) has impaired contraction. This study aimed to explore the expression of potassium channels related to contraction in myometrial smooth muscle cells (MSMCs) of AM. METHODS Uterine tissue samples from 22 patients (cases) with histologically confirmed AM and 12 (controls) with cervical intraepithelial neoplasia were collected for both immunohistochemistry and real-time polymerase chain reaction to detect the expression of large conductance calcium- and voltage-sensitive K + channel (BKCa)-α/β subunits, voltage-gated potassium channel (Kv) 4.2, and Kv4.3. Student's t-test was used to compare the expression. RESULTS The BKCa-α/β subunits, Kv4.2, and Kv4.3 were located in smooth muscle cells, glandular epithelium, and stromal cells. However, BKCa-β subunit expression in endometrial glands of the controls was weak, and Kv4.3 was almost undetectable in the controls. The expression of BKCa-α messenger RNA (mRNA) (0.62 ± 0.19-fold decrease, P < 0.05) and Kv4.3 mRNA (0.67 ± 0.20-fold decrease, P < 0.05) decreased significantly in the MSMCs of the control group compared with the AM group. However, there were no significant differences in BKCa-β subunit mRNA or Kv4.2 mRNA. CONCLUSIONS The BKCa-α mRNA and the Kv4.3 mRNA are expressed significantly higher in AM than those in the control group, that might cause the abnormal uterus smooth muscle contractility, change the microcirculation of uterus to accumulate the inflammatory factors, impair the endometrium further, and aggravate the pain.

Abstract
Introduction The present study aimed to investigate clinical, lifestyle, and environmental factors associated with endometrioma (OMA) and/or deep infiltrating endometriosis (DIE) as determined by case–control comparison [women with superficial peritoneal endometriosis (SUP) or no endometriosis], and compare differences between factor associated with endometriosis at a national level. Methods This was three countries (China, Russia, and France), case–control study in 1008 patients. Patients were identified and enrolled during their first routine appointment with their physician post-surgery for a benign gynecologic indication, excluding pregnancy. Retrospective information on symptoms and previous medical history was collected via face-to-face interviews; patients also completed a questionnaire to provide information on current habits. For every DIE patient recruited (n = 143), two women without endometriosis (n = 288), two SUP patients (n = 288), and two OMA patients (n = 288) were recruited. Results For the overall population, factors significantly associated (P ≤ 0.05) with DIE or OMA [Odds ratio (OR) >1] were: previous use of hormonal treatment for endometriosis [OR 6.66; 95% confidence interval (CI) 4.05–10.93]; previous surgery for endometriosis (OR 1.95; 95% CI 1.11–3.43); and living or working in a city or by a busy area (OR 1.66; 95% CI 1.09–2.52). Differences between regions with regard to the diagnosis, symptomatology, and treatment of endometriosis exist. Conclusion The findings provide insight into potential risk factors for endometriosis and differences between regions in terms of endometriosis management and symptomatology. Further investigations are required to confirm the associations found in this study. Trial registration ClinicalTrials.gov identifier, NCT01351051. Funding Ipsen.

Abstract
OBJECTIVE To investigate treatment effects of levonorgestrel-releasing intrauterine system (LNG-IUS) for adenomyosis with menorrhea in a prospective study. METHODS From December 2006 to December 2014, patients of symptomatic adenomyosis diagnosed by transvaginal ultrasound in outpatient or inpatient clinics of Peking Union Medical College Hospital were given the treatment of LNG-IUS. Before and after placement of LNG-IUS, all the patients' parameters were recorded prospectively, including scores of menstruation blood loss, carrying status of IUS, symptoms and scores of dysmenorrhea, biochemical indicators, physical parameters, menstruation patterns and adverse effects. Changes of pictorial chart scores of menstruation and distribution of anemia during follow-up were analyzed. RESULTS Totally 1 100 women meets inclusion criteria, among which 618 cases (56.18%, 618/1 100) had severe menorrhea, with median follow-up period of 28 months (range 1- 60 months), and accumulative carrying rate of 66% at 60 months follow-up. After placement of LNG-IUS, compared with baselines, pictorial chart scores and ratio of menorrhea had decreased significantly (all P<0.01), the scroes of menstruation were 157±34, 94±35, 70±33, 67±18, 67±20, 65±19, 66±19, 65±21 at 0, 3, 6, 12, 24, 36, 48 and 60 months respectively. During 24 months after placement of LNG-IUS, pictorial chart scores and distribution of anemia had improved significantly compared with preceding period (all P<0.01). We found no dependent factors predicting improvement of pictorial chart scores of menorrhea, which was neither relevant with simultaneous changes of menstruation patterns nor adverse effects (all P>0.05). CONCLUSIONS LNG-IUS is effective for adenomyosis of menorrhea. Improvement of menstruation blood loss is independent on patients characters, menstruation patterns or adverse effects.

Abstract
Background: The effect of endometriosis on obstetric outcomes is still ambiguous. The aim of our study was to determine the association between endometriosis and adverse obstetric outcomes in a cohort of Chinese women. Methods: A retrospective cohort study was undertaken to compare obstetric outcomes between 249 women with endometriosis and 249 women without endometriosis. All women were nulliparous and achieved singleton pregnancies naturally. Women with endometriosis were diagnosed during surgery and confirmed histologically. Odds ratios (ORs) and 95% confidence intervals (CIs) of measures of obstetric outcomes were calculated. Results: Women with endometriosis showed significantly increased risks of preterm labor (adjusted OR, 2.42; 95% CI, 1.05–5.57), placenta previa (adjusted OR, 4.51; 95% CI, 1.23–16.50), and cesarean section (adjusted OR, 1.93; 95% CI, 1.31–2.84). No significant differences were observed in the incidence of pregnancy-induced hypertension, fetal growth restriction, small for gestational age, placental abruption, or luteal support in the first trimester between the two groups. Conclusions: Women with endometriosis are at a higher risk of preterm labor, placenta previa, and cesarean section during pregnancy and need additional care.

Abstract
BACKGROUND Laparoscopic surgery in pregnant women has become increasingly more common; however, the safety of laparoscopy in this population has been widely debated in emergent situations and big size at bigger pregnant weeks. This study was to determine the characteristics of laparoscopic surgery for adnexal masses in different conditions during the second trimester of pregnancy. METHODS Between April 2002 and December 2011, 24 patients with suspected ovary cyst during the second trimester underwent laparoscopic surgery at the Peking Union Medical College Hospital retrospectively. Clinical data were collected retrospectively and patient's outcomes were analyzed. RESULTS The incidence of laparoscopic surgery for ovarian cysts during pregnancy was 0.12% of all laparoscopic gynecological surgeries performed at the hospital. No patients required conversion. There were 9 (37.5%) patients whose gestational age was no less than 16 weeks, and 15 patients whose gestational age was less than 16 weeks; no difference was noted in the operation time between the two groups (P > 0.05). Emergency surgery due to abdominal pain was performed in 4 (16.7%) patients, 2 (8.3%) of whom underwent simple salpingo-oophorectomy because of ovarian necrosis. The other patients underwent enucleation of the ovarian cyst. There were no severe complications. Twenty (83.3%) pregnant women delivered healthy term infants and 4 (16.7%) cases were lost to follow up. CONCLUSION Laparoscopic surgery for ovary masses is a safe and feasible procedure for the treatment of ovary cyst in different conditions during the second trimester, even if gestational age reaching 16-19 weeks or in emergency.

Abstract
Endometriosis has critical implications for women's quality of life. However, an overview of the current knowledge of this issue is limited. The objective of this systematic review was to determine the extent of endometriosis and its treatment upon women's health-related quality of life (HRQoL). PubMed, Embase, PsycoINFO, CINAHL and the Cochrane Clinical Trials were searched up to May 2012, and only studies using standardized instruments to evaluate HRQoL in women with endometriosis were selected. Our electronic searches identified 591 citations, of which 39 studies satisfied the inclusion criteria including nine qualitative studies and 30 treatment-related studies. Findings showed that endometriosis impaired women's HRQoL. Pain was strongly related to a poor HRQoL, and medical or surgical treatment could partially restore this impairment. No conclusive evidence was available on whether endometriosis imposed an additional impairment in HRQoL per se, apart from the decrease caused by chronic pelvic pain, or on the superiority of various hormonal suppression agents. The impacts of disease extent, duration and fertility status upon HRQoL were inconsistent. In summary, HRQoL was impaired in women with endometriosis, and medical or surgical treatment to alleviate pain could partially restore this impairment.

Abstract
OBJECTIVE To investigate the expression of transient receptor potential vanilloid subtype 1 (TRPV1) in uterosacral ligament and its correlation with pain in endometriosis. METHODS Total of 54 patients undergoing endometriotic lesions excision in uteroscaral ligament by laparoscopy due to pelvic pain were enrolled in this study. According to visual analogue scale (VAS) scores, 27 patients with VAS 5-10 were in group A and 27 patients with VAS 0-4 were in group B. In the mean time, 20 patients with dysmenorrhea without endometriosis (VAS: 0-4) were matched as group C. Specimens (including the sacro-ligaments of 20 women without endometriosis) were immunostained with specific antibodies of TRPV1. Western blot and real time PCR were performed to detect TRPV1 expression in endometriosis lesions and control group. RESULTS (1) Immunohistochemnistry: the positive area of TRPV1 was found in endometriotic lesions in uterosacral ligament in group A, B and tissue of uterosacral ligament group C. The semi-qualitification of TRPV1 expression were 3 in group A, 1 in group B and 1 in group C by immunohistochemistry staining. There was significantly different expression between group B and group A (P = 0.005) or group C (P = 0.027). (2) mRNA expression:the expression of TRPV1 was 1.84 in group A, 0.80 in group B, 0.24 in group C, respectively. With higher VAS scores, the expression of TRPV1 exhibited increasing trends. The expression of TRPV1 mRNA was higher in group A than that in group B (P = 0.022). There was statistically different expression between group B and group C (P = 0.031). (3) Western blot: the expression of TRPV1 protein was 0.63 in group A, 0.19 in group B, 0.02 in group C. There was significant differences between group A and group B (P = 0.022), and between group B and group C (P < 0.01). CONCLUSION The expression of TRPV1 was correlated with the degree of pain in patient with endometriosis.

Abstract
BACKGROUND Endometriosis is a controversial and enigmatic disease. Deep infiltrating endometriosis (DIE) is responsible for painful symptoms and is the least understood type of endometriosis. Little work has been devoted to define the location of DIE lesions and its relationships with pain. The aim of the study was to investigate the relationship between the anatomical distribution of DIE lesions and pain symptoms. METHODS Clinical data from 354 patients between May 2003 and December 2007 with laparoscopically diagnosed endometriosis were collected including 177 DIE patients and 177 non-DIE patients. The pain symptoms, including dysmenorrhea (DM), chronic pelvic pain (CPP, defined as intermittent or permanent pelvic pain, not related to the menstruation and longer than 6 months), deep dyspareunia (pelvic pain at intercourse) and dyschezia (pelvic pain with defecation), were recorded for every patient before operation. Endometriotic lesions were recorded by their anatomical distributions, the depth of infiltration and lesion colors. And the relationship between the anatomical distribution of DIE lesions and pain symptoms was analyzed. Pearson's chi-square test or Fisher's exact test, one-way analysis of variance (ANOVA) and linear regression and binary Logistic regression were used for statistical analysis. RESULTS The duration ((13.79 ± 3.94) years) of pain suffering in DIE patients was much longer than that of non-DIE patients (P < 0.01). In DIE patients, 60.7% of the uterosacral ligament (USL) nodules were bilateral (P < 0.01); 44.6% of the cul-de-sacs were completely blocked. Rectum invasion was observed in 19.9% of DIE patients (P = 0.03); pelvic adhesion was also more common. Up to 98.41% of the deep infiltrative lesions were located in the posterior pelvic compartment. DIE lesions were also found in bladder (1.58%), USL (67.08%), cul-de-sac (12.02%), recto-vaginal septum (12.66%), rectum and rectosigmoid junction (2.85%) and ureter (3.80%). The odds ratio of USL-DIE for CPP, deep dyspareunia, dyschezia were 2.52, 1.29 and 2.24 respectively. And the depth of infiltration correlated with the severity of dysmenorrhea. CONCLUSIONS DIE lesions were associated with severe pain symptoms. The main distribution of DIE lesions was in the posterior pelvic compartment, and was more widespread and severe in DIE patients. Moreover, resection of these DIE lesions are very important to treat the pain symptoms.

Abstract
BACKGROUND Endometriosis (EM) is a benign gynecologic disease predominantly found in women of reproductive age. However, its pathogenesis is still poorly understood. Our experiment was designed to establish a stable and reliable cultural environment for coculture of endometrium and peritoneum, so as to observe the adhesion/invasion ability of endometrium from patients with or without EM. METHODS Endometria of secretory phase and peritoneum were sampled from 6 women with endometriois during laparoscopy. Six with ovarian teratoma or simple ovarian cyst were taken as control. We cocultured endometrium and peritoneum into four groups (endometrium from EM cultured with peritoneum from EM, endometrium from control cultured with peritoneum from control, endometrium from EM cultured with peritoneum from non-EM and the endometrium from control cultured with peritoneum from EM) to observe the adhesion/invasion process in gas-liquid surface culture and in-medium culture. Specimens were collected at 1 hour, 6 hours, 12 hours, 24 hours, 2 days, 3 days, 4 days, 5 days, 6 days and 7 days for histology, immunofluorescence and immunohistochemical analysis on cytokeratin 8 (CK8) and CD10. RESULTS The gas-liquid surface culture was superior to in-medium culture for the maintenance of tissue morphology and survival of endometrium. CK8 immunoflurescence demonstrated no remarkable difference in adhesion process between patients with and without EM. CD10 immunochemistry manifested frequent invasion of endometrial stromal cells from EM patients into peritoneum of up to 3 days culture, while the endometriotic cells from non-EM patients did not invade into peritoneum. CONCLUSIONS Gas-liquid surface culture is a suitable model for observing the early events in EM lesion formation. Endometrium from patients with EM showed increased invasion capacity during coculture, which might help to explain the etiology of endometriosis.

Abstract
OBJECTIVE To determine the prevalence of cervical type-specific human papillomavirus (HPV) infection as well as risk factors associated in Tibet Autonomous Region of China. METHODS A cluster sampling study was performed in Lasa, Rikaze and Naqu of Tibet. An epidemiological questionnaire was applied and 3036 cervical specimens were obtained for liquid-based cytology and HPV DNA detection. Statistical analysis included Wald Chi-square and stepwise logistic regression model. RESULTS The overall HPV prevalence of involved 3036 women was 9.19% (279/3036), of which 7.05% (214/3036) of the women were infected by high-risk types (including 14 sorts of types) and 2.14% (65/3036) by low-risk types (including 6 sorts of types). There were no significant differences of HPV prevalence between age groups (P = 0.936), race (P = 0.718) and areas (P = 0.746), respectively. Twenty-one types of HPV were detected, of which HPV16 (1.52%) was the most common type, followed by HPV33 (1.42%), HPV58 (1.22%), HPV52 (1.15%), and HPV31 (1.05%). HPV type distribution was varied by age. Of the 279 HPV infected women, 14.3% (40/279) exhibited multiple HPV infections. Independent risk factors for HPV infection were smoking (P = 0.027), number of sex partners (P = 0.198) and early age of first intercourse (P = 0.237). CONCLUSION The overall prevalence of HPV infection in Tibet Autonomous Region is lower than that in China or abroad, in which the most common genotype is HPV16 and the independent risk factors for HPV infection included early age of first intercourse, smoking, and number of sex partners.

Abstract
OBJECTIVE To investigate the effects of progesterone and progestin on the expressions of regulated on activation, normal T cell expressed and secreted (RANTES) in eutopic endometrium from patients with endometriosis. METHODS We collected the samples of endometrium from patients with endometriosis before operation or after insertion of levenorgestrel releasing intrauterine system (LNG-IUS), administration of oral medroxyprogesterone (MPA), or injection of gonadotrophic hormone releasing hormone agonist (GnRHa). Reverse transcription-polymerase chain raction was used to assay the expression of RANTES mRNA. On the other hand, progesterone (Po) and tumor necrosis factor-alpha (TNFalpha) of different concentrations and different manners were used to treat cultured cells in vitro. RANTES secretion was evaluated in the culture medium using ELISA. In order to evaluate the effect of Po on the secretion of RANTES under stimulation of TNFalpha, the cells were cultured in medium containing 100 U/ml TNFalpha and Po of different concentrations for 24 hours. After the pretreatment of Po for 48 hours at different concentrations, TNFalpha (100 U/ml, 16 h) was added to observe whether Po inhibits RANTES or not. RESULTS The expression of RANTES mRNA in eutopic endometrium of patients with endometriosis was significantly higher than in control group (28.0 +/- 9.0 vs. 22.0 +/- 5.6, P < 0.05). Following the exposures to LNG-IUS (24.0 +/- 4.2 vs. 25.9 +/- 4.2, P > 0.05) or GnRHa (23.0 +/- 12.9 vs. 26.9 +/- 5.2, P > 0.05), the expression of RANTES mRNA had no change. MPA significantly increased the expression of RANTES mRNA (42.6 +/- 3.1 vs. 24.3 +/- 5.7, P < 0.05). Po itself had no significant effect on the secretion of RANTES. Stimulated by Po and TNFalpha at the same time, the secretion of RANTES significantly increased. After pretreatment with Po for 48 hours, the reaction of RANTES to the stimulating effect of TNFalpha was down-regulated. CONCLUSION The eutopic endometrium of patients with endometriosis has high chemotactic activity. It may be feasible to prevent and treat endometriosis with progestins.

Abstract
OBJECTIVE To investigate the apoptosis-related mechanisms of levenorgestrel-releasing intrauterine system (LNG-IUS), oral medroxyprogesterone (MPA), and injective gonadotrophic hormone releasing hormone agonist (GnRHa) on eutopic endometrium of patients with endometriosis. Methods We collected the samples of endometrium from patients with endometriosis before operation and after insertion of LNG-IUS, administration of oral MPA, or injection of GnRHa. The ultrastructure of endometria was observed and compared by electron microscopy. Apoptotic cells were assessed by the terminal deoxynucleotidyl transferase-mediated deoxy-UTP nick-end labeling (TUNEL) assay, and the expressions of Bax, Fas, and Fas-L mRNA were determined by semi-quantitative reverse transcription-polymerase chain raction. Results After have been exposured to LNG-IUS, the apoptotic rate of endometrial epithelial cells and stromal cells increased from (24. 4 +/- 35.0)% to (51.0 +/- 37.8)% (P = 0.027) and (35.3 +/- 30.2)% to (76.4 +/- 11.2)% (P = 0.008), respectively. The degree of apoptosis under transmission electron microscopy was in an order of GnRHa > LNG-IUS > MPA. The expression of Fas-L mRNA in eutopic endometrium of patients with endometriosis was significantly higher than that of the normal control (P < 0.05). The expressions of three apoptosis-related proteins had no significant difference. CONCLUSION Medical treatments can increase the apoptosis of eutopic endometrial cells, and such effect was strongest in GnRHa and relatively weaker in LNG-IUS and MPA.

Abstract
OBJECTIVE To investigate ureteral injury during gynecological laparoscopic surgeries. METHODS From January 1990 to December 2005, 12 868 gynecological laparoscopic surgeries were conducted in Peking Union Medical College Hospital with 12 ureteral injuries reported. The present study investigated several aspects, including surgical indications, uterine size, pelvic adhesion, operative procedures, symptoms, diagnostic time and methods, injury site and type, subsequent treatment, and prognosis. RESULTS The incidence of ureteral injury was 0.093% (12/12 868) in all cases, 0.42% (11/2 586) in laparoscopic hysterectomy [laparoscopically assisted vaginal hysterectomy (LAVH) or total laparoscopic hysterectomy (TLH)], and 0.01% (1/10 282) in non-LAVH surgeries. Enlarged uterus, pelvic adhesion, and endometrosis were risk factors associated with ureteral injury. Only one injury was found intraoperatively while others were found postoperatively. The injury sites were at the pelvic brim (2 cases) or the lower part of ureter (10 cases). Patients were treated with ureteral stenting (effective in 2 cases) or laparotomy and open repair. Prognoses were favorable in most cases. CONCLUSIONS Most laparoscopic ureteral injuries occur during laparoscopic hysterectomy. Further evaluation is required when ureteral injury is suspected, and surgical repair is the major treatment for ureteral injury.

Abstract
OBJECTIVE To detect the concentrations of prostaglandin E2 (PGE2) and bcl-2 in sera and peritoneal fluid of women with endometriosis. METHODS The study group included 36 samples of peritoneal fluid and serum respectively from patients with endometriosis, and control group included 30 samples of peritoneal fluid and serum respectively from patients without endometriosis (either ovary cyst or uterine myoma). The peritoneal fluids were collected at the time of laparoscopic operation, and the sera were collected before surgery. Concentrations of PGE2 and bcl-2 were determined by enzyme linked immunosorbent assay (ELISA). RESULTS The peritoneal fluid concentrations of PGE2 and bcl-2 in study group were significantly higher than that of control group, (1987 +/- 532) ng/L vs (386 +/- 215) ng/L, (177 +/- 53) U/L vs (86 +/- 21) U/L, (P < 0.05); and the PGE2 levels of severe endometriosis were significantly higher than that of mild endometriosis, (2221 +/- 1352) ng/L vs (1694 +/- 381) ng/L, (P < 0.01). The serum concentrations of PGE2 and bcl-2 in study group were significantly higher than that of control group, (3787 +/- 514) ng/L vs (129 +/- 97) ng/L, (96 +/- 44) U/L vs (53 +/- 40) U/L, (P < 0.01). Serum PGE2 concentrations of severe endometriosis were significantly higher than that of mild endometriosis, (964 +/- 290) ng/L vs (590 +/- 362) ng/L, (P < 0.01). CONCLUSIONS The concentrations of PGE2 and bcl-2 in peritoneal fluid are increased in endometriosis. The concentrations of PGE2 and bcl-2 are associated with the extent of endometriosis lesions.

Abstract
OBJECTIVE To evaluate the clinical aspects of mature ovarian teratoma. METHOD We retrospectively studied 695 patients operated in PUMC Hospital between January 1990 and December 2000. RESULTS Laparoscopy surgery had shorter hospitalization day, less blood loss during surgery, shorter operation time compared with laparotomy (P < 0.001). Routine contralateral wedge resection was done in 601 cases, among which 459 had normal inspection and palpatation. Only one (0.22%) was pathologically confirmed bilateral tumor. Torsion was the major complication (7.5%). Average tumor size of torsion was (10.2 +/- 4.5) cm. Probability of torsion increased as the tumor enlarged, which was less than 4.4% when the tumor size was less than 6 cm and greater than 10% if size greater than 8 cm. Rupture, infection, and malignant transformation were rare. CONCLUSIONS Laparoscopy is superior to laparotomy in the treatment of mature ovarian teratoma. If the contralateral ovarian is within normal configuration, contralateral wedge resection is unnecessary. When the tumor size is greater than 8 cm in diameter, it will have more chance to twist.

Abstract
Steroidogenesis in the placenta has been studied widely, but little is known about steroid metabolism in ectopic pregnancy. Previous studies have indicated that trophoblast invasion and placentation in the uterus and the fallopian tube may be controlled by similar mechanisms. As far as 17beta-estradiol (E(2)) production is concerned, it has been well demonstrated that its biosynthesis in the placenta involves the action of P450 aromatase (P450arom) and 17beta-hydroxysteroid dehydrogenase type 1 (17HSD1). The purpose of this study was to characterize the expression pattern of P450arom and 17HSD1 at the fetal-maternal interface, particularly in various trophoblast cells, in tubal pregnancy. Using in situ hybridization, P450arom mRNA was localized in syncytiotrophoblast (ST) cells, which are mainly responsible for hormone production during pregnancy, whereas no signal was detected in villous cytotrophoblast (VCT), column CT and extravillous CT (EVCT) cells. Immunohistochemical assays revealed that 17HSD1 is present in ST cells, a large portion of EVCT cells and 20% of column CT cells. On the other hand, no expression of 17HSD1 was detected in VCT cells. In addition, 17HSD1 was found in epithelial cells of the fallopian tube. Interestingly, the expression level of 17HSD1 in fallopian tube epithelium during tubal pregnancy was significantly higher than that during normal cycle. Our data provide the first evidence that normal and tubal pregnancies possess identical expression of P450arom and 17HSD1 in ST cells and therefore, similar E(2) production in the placenta. Further, the association of 17HSD1 with EVCT cells indicates that 17HSD1 perhaps play a role in trophoblast invasion. Finally, increased expression of 17HSD1 in epithelial cells of fallopian tube may lead to a local E(2) supply sufficient for the maintenance of tubal pregnancy.

Abstract
OBJECTIVE To investigate the expression of vascular endothelial growth factor (VEGF) mRNA and thrombospondin-1 (TSP-1) mRNA in endometriosis. DESIGN Molecular studies in human tissue. SETTING Department of Obstetrics and Gynecology, Peking Union Medical College Hospital, Peking Union Medical College, Chinese Academy of Medical Sciences, Beijing, P. R. China. PATIENT(S) Patients undergoing laparoscopy for infertility or other benign gynecologic conditions. INTERVENTION(S) Biopsies were taken from endometriotic lesions (red peritoneal lesion, ovarian endometrioma, and unterosacral ligament nudule) and eutopic endometrium during laparoscopy. MAIN OUTCOME MEASURE(S) mRNA expression from endometriotic lesion and eutopic endometrium was analyzed by reverse transcriptase polymerase chain reaction (PCR) and Northern blotting. RESULT(S) Among the endometriotic lesions, red peritoneal lesions expressed higher levels of VEGF mRNA and lower levels of TSP-1 mRNA, whereas ovarian endometrioma expressed lower levels of VEGF mRNA and higher levels of TSP-1 mRNA. Eutopic endometrium of women with endometriosis had higher expression levels of VEGF mRNA and lower expression levels of TSP-1 mRNA than that of women without endometriosis. CONCLUSION(S) The expression of VEGF and TSP-1 in endometriotic lesions appears to be associated with the extent of their neovascularization. The imbalance in expression of VEGF and TSP-1 in the endometrium may play a role in the development of endometriosis.

Abstract
Two methods of measuring the amniotic fluid index (AFI) were subjected to tests of intra- and interobserver reproducibility. In the first method, amniotic fluid in each quadrant was measured by using the deepest pool perpendicular to the floor; in the second method, amniotic fluid in each quadrant was measured by using the deepest pool perpendicular to the uterine contour. Intraobserver and interobserver variability were assessed by using one-way analysis of variance and limits of agreement, respectively. Intraobserver standard deviations were all < 9 mm. When the AFI was measured using the first method, there was an inverse relationship between the interobserver difference and mean values of AFI. Plots of the differences between observers against their means showed that the lower the AFI, the greater the interobserver variability. No such correlation was noted when the AFI was measured by the second method. The limits of agreement (within which 95% of interobserver differences lie) were comparable for the two methods [(-42 mm to 29.4 mm) and (-46.4 mm to 41.6 mm), respectively]. The results suggest that the amniotic fluid index measured by the second method is more reproducible, especially in the presence of reduced amniotic fluid.
