Objective To evaluate the diagnostic and prognostic value of serum CA19-9,CA125 and CP2 in mucinous ovarian tumors.Methods In this retrospective study,the serum CA19-9,CA125 and CP2 levels of 273 hospitalized patients with ovarian tumors of either mucinous or non-mucinous type were analyzed.Results(1)CA19-9 had the biggest area under chive(AUC)in mucinous tumors followed with CA125 while CA125 and CP2 had bigger AUC in non-mucinous tumor.(2)For the diagnosis of mucinous tumors,CA19-9 and CA125 combination showed a greatly increased sensitivity compared with CA19-9 or CA125 alone(93.8%versus 75.0%and 66.7%,P＜0.05)with no significant improvement of the specificity(P＞0.05).For the diagnosis of non-mucinous tumors,CA125 and CP2 combination showed an increased sensitivity compared with CA125 or CP2 alone(85.0%versus 80.7%,P＞0.05,85.0%versus 70.6%,P＜0.05)with no significant improvement of the specificity(P＞0.05).(3)Seventy percent of tumor marker-positive patients could undergo cytoreductive surgery.Compared with those who could not undergo cytoreductive surgery,they were more likely to have normal tumor marker two months after surgery (P＜0.05)and longer interval to re-elevation of tumor markers(P＞0.05),with lower reeurrence and death rate (P＜0.05).All of the 20 tumor marker-negative patients could have eytoreduetive surgery with only 10%recurrence.(4)CA19-9 inereased mainly in recurrent mucinous tumor,while CA125 increased dominantly in recurrent non-mueinous tumor.(5)The survival rate of CA125 and CP2 positive patients was much lower than CA125 and CP2 negative patients(P＜0.05),while the survival rate was similar between CA19-9 positive and CA19-9 negative patients.Conclusions CA19-9 is a sensitive index for diagnosis of mucinous ovarian tumors.Combination of CA19-9 with CA125 can improve the sensitivity of diagnosis and postoperative monitoring of mucinous ovarian tumors.Combination of CA125 with CP2 is more valuable in the diagnosis of non-mucinous ovarian tumors.

Objective To investigate the clinical and pathological characteristics of atypical polypoid adenomyoma (APA) for improvement of the diagnosis, different diagnosis and treatment of the disease. Methods The clinical data, pathological characteristics, and the follow-up information were retrospectively analyzed in 27 cases of APA admitted in Peking Univeristy People′s Hospital from 2007 to 2016. Results The median age was 42.6 years old (range 25-60 years old). Fifteen patients were nullipara, 2 patients were postmenopausal. The most common presenting symptom was abnormal uterine bleeding (81%,22/27). Leisions were obtained by using hysteroscopy in 23 cases, hysterectomy 3 cases and dilatation and curettage 1 case. Fertility preserving treatments were performed in 10 patients who had strong desire for fertility, among which 1 case progressed into endometrial carcinoma. Among 15 patients underwent hysterectomy and (or) bilateral salpingo-oophorectomy, 9 cases of them had endometrial atypical hyperplasia. Endometrial carcinoma along with APA were found in three patients, 2 cases of them underwent hysterectomy and bilateral salpingo-oophorectomy and pelvic lymphadenectomy, the other one received medication for fertility preservation. Follow up information were available in 24 cases(89%,24/27)with a median follow up of 46 months (range 4-108 months), 1 case recurred and 1 case progressed into endometrial carcinoma. One case died of other malignancy, while the other patients were alive. Conclusions APA is a rare uterine neoplasm mixed with epithelial and mesenchymal component. It occurs mostly in childbearing-age women and its diagnosis is dependent on pathology. Although it′s clinical course is benign, there is risk of co-existance of endometrial carcinoma and endometrial atypical hyperplasia. For those who has desire of fertility, the treatment strategy is completely removed the lesion and closely followed up. For those who do not desire to preserve fertility, hysterectomy may be an option.

Objective To analyze the prognostic factors associated with three-year survival outcome in patients with serous ovarian adenocarcinoma by classification tree.Methods Retrospectively we analyzed 81 cases with serous ovarian adenocarcinoma who had 3-year clinical outcomes and were hospitalized in People's Hospital from Jan 1991 to Dec 2003 by classification and regression trees(CART)software.Establish the classification tree.Results Among the factors that were associated with the 3-year survival rate,age was the most important factor,other factors in turn were International Federation of Gynecology and Obstetrics(FIGO)stage,lymphoid metastasis,residual size after operation,chemotherapy and pathologic grade.By substitution variable analysis,it was demonstrated that there was cross interaction between age and residual size as well as age and chemotherapy.Conclusion Age,FIGO stage,lymphoid metastasis,residual size after operation,chemotherapy and pathologic grade are important prognostic factors related with three-year survival probability of serous ovarian adenocarcinoma patients.

Objective To construct cyclic clinical skill training system and to evaluate its application effect in clinical practice in department obstetrics and gynecology.Methods Cyclic clinical skill training system was established in department obstetrics and gynecology.Totally 104 eight-year program clinical medicine students of grade 2005 and 2006 in people's hospital of Peking university were enrolled as the research object and were divided into control group ( n =54,grade 2005) and experimental group (n =50,grade 2006 ).Students of control group were taught by normal teaching method and contacted with patients in clinical practice while those in experimental group were taught by cyclic clinical skill training system. (theoretical test before practice-simulated training-real practicetheoretical test after practice).Results of theoretical test after practice were compared between the two groups,using statistical t test.Results At the end of internship,students in experimental had higher scores in theoretical test than those in control group,with statistical differences (88.70 vs.85.02,P ＜0.05).Students' skill test scores were (77.04 ± 10.35 ) and (45.61 ± 14.42) before practice while (84.59 ± 10.10) and (68.78 ± 10.83) after practice,with statistical differences ( P ＜ 0.01 ).Conclusions Cyclic clinical skills training system can promote students' skills of obstetrics and gynecology,therefore worth promoting.

Objective:To compare the clinical and prognostic characteristics of ovarian endometrioid carcinoma (OEC) patients with synchronous endometrial lesions and patients with pure OEC.Methods:A retrospective review of the medical records of patients received initial treatment and a postoperative pathological diagnosis of OEC at Peking University People′s Hospital between August 1998 and December 2017 were performed. According to the inclusion criteria, a total of 56 patients with OEC were included in the study, including 13 patients concurrent with simultaneous endometrial lesions (Group A) and 43 patients with pure OEC (Group B).Results:Patients with synchronous endometrial lesions accounted for 23% (13/56). Mean age of Group A at diagnosis was (44.9±8.3) years old, 2/13 of patients were postmenopausal, and no one had a history of hypertension, the first symptom of 5/13 people was irregular vaginal bleeding. Mean age of Group B patients at diagnosis was (52.7±10.2) years old, 53% (23/43) of patients were postmenopausal, and 28% (12/43) patients had the history of hypertension, the first symptom of 4 (9%, 4/43) people was irregular vaginal bleeding. The differences of age, menopause status, history of hypertension and initial symptoms between the two groups were statistically significant (all P<0.05). There were no significant differences in fertility history, dysmenorrhea history, age of menarche, history of endometriosis, preoperative and postoperative CA 125 level, International Federation of Gynecology and Obstetrics (FIGO) stage, tumor grade, metastatic site and platinum-based chemotherapy drug resistance between the two groups (all P>0.05). The overall 5-year survival rate of OEC patients was 91.6%, and the overall 5-year progression-free survival rate was 76.6%. Among them, the 5-year survival rate of the OEC concurrent with simultaneous endometrial lesions group was 80.2%, and the pure OEC group was 93.4%; the 5-year progression-free survival rate of the OEC concurrent with simultaneous endometrial lesions group was 74.1%, and the 5-year progression-free survival rate of the pure OEC group was 77.3%. There were no significant differences between the two groups (all P>0.05). Multivariate analysis showed that the independent factors for the prognosis of OEC patients were FIGO stage ( P=0.006) and residual lesion size ( P=0.020). Conclusions:OEC patients have a high proportion of simultaneous endometrial lesions. OEC with simultaneous endometrial lesions are younger than patients with pure OEC. Synchronous endometrial lesions do not affect the prognosis of patients with OEC.

Objective To evaluate the efficacy and tolerability of the combination of oxaliplatin,ifosfamide and epirubicin(IAP)in treatment of recurrent or platinum-resistant ovarian cancer patients.Methods A total of 25 patients received the combined chemotherapy of ifosfamide(3-4 g/m2),epirubicin(50-60 mg/m2)and oxaliplatin(130 mg/m2).The cycles were repeated every 21 days.The efficacy and toxicity were evaluated in 21 patients who received more than 2 cycles of IAP chemotherapy.Results The overall response rate was 71%,with a complete response in 10(48%),partial response in 5(24%),stable disease in one(5%),and disease progression in 5(24%).The median progression-free and overall survival time were 11(1 to 33)months and 31(1 to 71)months.While overall response rate was 60%in 10 patients with primary platinum resistant,and 88%in 8 patients with secondary platinumresistant.Grade Ⅲ-Ⅳ myelosuppression rate wss 30%.The most common non-hematologic toxicity was perineurotoxicity(38%).Conclusions The combination of oxaliplatin,ifasfamide and epirubicin appears to be effective for recurrent or platinum-resistant ovarian cancer patients as salvage chemotherapy and the toxicity is also tolerable.However,it needs to be evaluated by multiple clinical trials.

Objective:To construct the core indicators for entrustable professional activities in specialists in obstetrics and gynecology.Methods:A study group was formed by the specialists in obstetrics and gynecology and the experts in medical education. The core indicators for entrustable professional activities were constructed for the specialists in obstetrics and gynecology based on literature review and clinical practice, and then the Delphi method was used to conduct two rounds of expert letter consultation for screening and optimization from March 2021 to January 2023 to further identify the core indications.Results:The expert positive coefficient was 100% for the two rounds of consultation, with an expert authority coefficient of 0.82, and the Kendall's coefficient of concordance was 0.221 and 0.213, respectively (both P<0.01). Ten core indicators and their content descriptions were constructed for entrustable professional activities in obstetrics and gynecology specialists, and the experts had a degree of recognition of more than 80% for the importance of these ten entrustable professional activities, with a coefficient of variation of <0.25. This study determined the expected entrustable level of each indicator for specialists at the completion of the course, which ranged from grade 3 to 5; the highest level of 4.48 was observed for the diagnosis and treatment of outpatients, which was between the levels of mastery and expert; the lowest level of 3.52 was observed for laparoscopic hysterectomy, which was between the levels of competency and mastery. Conclusion:This study preliminarily constructs the core indicators for entrustable professional activities in specialists in obstetrics and gynecology, which provides a new exploration for the standardized training of specialists.

Abstract: Objective　To understand the epidemiological characteristics of the migratory bird population with hypertension in Hainan and to provide a basis for the health management of the migratory bird population. Methods　One hundred and eighty migratory birds with hypertension who had lived in in the Mangrove Bay community of Chengmai, Hainan for 3 months or more were selected as the study population. Demographic data, including gender, age, ethnicity, occupation, medication use, family history of hypertension, hometown living environment, Hainan living environment (presence of water area and greenbelt around the residence, type of water area and greenbelt), smoking and alcohol consumption, and height and weight were collected by questionnaire and physical examination to investigate the epidemiological characteristics of the study subjects, and unconditional dichotomous logistic regression analysis was used to identify factors affecting the reduction of blood pressure among the hypertensive migratory bird population before and after taking medication in Hainan. Results　A total of 180 study subjects were included, including 77 (42.8%) males and 103 (57.2%) females, with 78 (43.3%) subjects aged ≤65. The hypertension levels were: 87 (48.3%) had normal high blood pressure, 56 (31.1%) had grade 1 hypertension and 37 (20.6%) had grade 2 hypertension. The higher the blood pressure classification, the lower the percentage of migratory individuals whose blood pressure dropped during their stay in Hainan. Age, hypertension classification, dietary habits, living environment, body mass index (BMI), and alcohol consumption were associated with a decrease in blood pressure during Hainan among the study participants who took hypertension medication regularly. Salty diet (OR=2.778, 95%CI:1.070-7.213, P=0.036) and alcohol consumption (OR=2.686, 95%CI:1.042-6.925, P=0.041) were unfavorable factors for lower diastolic blood pressure before taking medication; overweight (OR=3.487, 95%CI:1.306-9.310, P=0.013) was an unfavorable factor in the reduction of diastolic blood pressure after taking medication. Conclusion　The blood pressure reduction is more significant in migratory individuals in migratory individuals under 65 years old, with a light diet, no alcohol consumption and normal BMI. Environmental factors, age, dietary habits and lifestyle are the main causes of blood pressure, which can provide a reference basis for the health management of the migratory birds with hypertension in Hainan.
