Ovarian tissue cryopreservation and transplantation is currently the only feasible method for preserving both fertility and ovarian endocrine function in prepubertal female patients. It is indicated for those requiring gonadotoxic therapies such as chemo-therapy, radiotherapy, or bone marrow transplantation for malignant diseases, as well as for non-malignant diseases, including immunologic, metabolic, and hematologic benign diseases requiring bone marrow transplantation, and other populations at high risk of premature ovarian insufficiency. The procedure involves laparoscopic retrieval of ovarian tissue, typically via unilateral oophorectomy in young patients, followed by slow-programmed cryopreservation. When the primary disease is cured and fertility or hormonal function restoration is desired, the tissue is thawed and transplanted, most commonly to an orthotopic site. For patients at high risk of ovarian malignancy involvement, pre-transplantation assessment of minimal residual disease in the ovarian cortex is performed using histo-pathology and molecular biology techniques. Globally, while ovarian tissue cryopreservation and transplantation has led to over 300 live births, the majority result from tissue cryopreserved after puberty. Successful restoration of puberty and subsequent live births following transplantation of tissue frozen before puberty, although demonstrated in reported cases, remain less common. Therefore, this review systematically summarizes recent advances in the indications, current application status, timing and strategies of ovarian tissue cryopreservation and transplantation, risk assessment of tumor cell reintroduction, and clinical outcomes in prepubertal patients. It also discusses the potential value and current challenges of combining this approach with invitro oocyte maturation techniques, ainming to provide practical references for clinical practice.

Threatened abortion is a common disease of obstetrics and gynecology and one of the diseases responding specifically to traditional Chinese medicine （TCM）. The China Association of Chinese Medicine organized experts in TCM obstetrics and gynecology， Western medicine obstetrics and gynecology， and pharmacology to deeply discuss the advantages of TCM and integrated Chinese and Western medicine treatment as well as the medication plans for threatened abortion. After discussion， the experts concluded that chromosome， endocrine， and immune abnormalities were the key factors for the occurrence of threatened abortion， and the Qi and blood disorders in thoroughfare and conception vessels were the core pathogenesis. In the treatment of threatened abortion， TCM has advantages in preventing miscarriages， alleviating clinical symptoms and TCM syndromes， relieving anxiety， regulating reproductive endocrine and immune abnormalities， personalized and diversified treatment， enhancing efficiency and reducing toxicity， and preventing the disease before occurrence. The difficulty in diagnosis and treatment of threatened abortion with traditional Chinese and Western medicine lies in identifying the predictors of abortion caused by maternal factors and the treatment of thrombophilia. Recurrent abortion is the breakthrough point of treatment with integrated traditional Chinese and Western medicine. It is urgent to carry out high-quality evidence-based medicine research in the future to improve the modern diagnosis and treatment of threatened abortion with TCM.

Objective:To evaluate the efficacy of Yiqi Yangyin Jiedu Decoction in the treatment of patients with pulmonary nodules and qi-yin deficiency syndrome after early lung cancer surgery.Methods:Randomized controlled trial was conducted. A total of 76 patients with lung nodules and qi-yin deficiency syndrome after early lung cancer surgery at the Oncology Department of Longhua Hospital Affiliated to Shanghai University of Traditional Chinese Medicine from March to September 2020 were selected and randomly divided into two groups using a random number table method, with 38 cases in each group. The control group received symptomatic treatment, while the treatment group took Yiqi Yangyin Jiedu Decoction from the first day after enrollment. Both groups were treated for 6 months and followed up for 2 years. TCM syndrome scores before and after treatment were evaluated; the patients' activity status was evaluated using the Eastern Oncology Collaborative Group Activity Status (ECOG PS) score in the United States, and electrochemiluminescence was used to detect carcinoembryonic antigen (CEA) and neuron specific enolase (NSE). Flow cytometry was used to detect the percentage of T lymphocyte subsets CD3 +and CD4 +, and ELISA was used to detect TGF-β Horizontal. The patients' weight was recorded and their weight changes after treatment were observed. Adverse reactions during treatment were observed and recorded, the efficacy of TCM syndromes and pulmonary nodules was evaluated. Results:During the observation period, one case was lost to follow-up in the treatment group and three cases were lost to follow-up in the control group. Finally, 37 cases in the treatment group and 35 cases in the control group completed the observation. After the treatment, the panting (0.27±0.07 vs. 0.68±0.12, t=17.66), spontaneous sweating and night sweating (0.16±0.16 vs. 0.79±0.16, t=16.55) score of the treatment group were lower than those in the control group ( P<0.01); insomnia (0.15±0.08 vs. 0.54±0.13, t=15.52) score of the control group was lower than that of the treatment group ( P<0.01). The effective rate of TCM syndrome in treatment group was 81.08% (30/37), higher than 54.29% (19/35) in control group ( Z=-2.00, P=0.040). After the treatment, the ECOG PS score stability rate in the treatment group was 89.19% (33/37), higher than 82.86% (29/35) in control group, without statistical significance ( χ2=0.19, P>0.05). The increase and stable rate of body weight was 88.10% (32/37) in treatment group and 62.86% (22/35) in control group ( χ2=5.36, P<0.05). After 2-year follow-up, the control rate of pulmonary nodules in the treatment group was 91.89% (34/37), while in the control group it was 65.71% (23/35). The difference between the two groups was statistically significant ( χ2=7.47, P<0.01). After the treatment, the level of NSE [(12.54±2.52)ng/L vs. (13.85±2.71)ng/L, t=-2.12], TGF-β [(218.38±102.63)ng/L vs. (301.24±193.69)ng/L, t=-2.29] in treatment group were lower than those in the control group ( P<0.05), and the level of CD3 +T cells [(70.60±7.90)% vs. (65.99±9.27)%, t=2.32] in treatment group was higher than that of the control group ( P<0.05). Conclusion:Yiqi Yangyin Jiedu Decoction can delay the development of pulmonary nodules in patients after early lung cancer surgery, increasing the body weight of patients, relieving the TCM syndromes and improve the immune function of patients, with the potential to prevent and treat the occurrence and development of early lung cancer.

Menopausal hormone therapy(MHT)is used to treat menopausal complaints including the genitourinary syn-drome of menopause,to prevent osteoporosis,and to treat bleeding problems.Since these can be the indications also in young women,especially with POI(premature ovarian insufficiency)or with surgical menopause(bilateral oophorectomy),also the old term"Hormone Replacement Therapy(HRT)"is still used.The effective component is the estrogen component without relevant difference in the efficacy of the various MHT-preparations.Addi-tional preventive benefits are reduction of cardiovascular disease(including prevention of diabetes mellitus and metabolic syndrome),reduction of colon cancer,and perhaps also Alzheimer's disease,if started within a"win-dow of opportunity",i.e.in perimenopause or within 6-10 years after menopause.Primary indication for progestogen addition is to avoid the development of estrogen-dependent endome-trial cancer,i.e.addition not recommended in hysterectomized women.Two main schedules,sequential-or continuous-combined estrogen/progestogen regimens,are used for treatment of bleeding problems.For this and for optimizing menstrual regulation detailed recommendations are given including proposed dosages for the available different progestogens if added to oral or transdermal estradiol in different estrogen dosages.The WHI-study demonstrated the main risks using MHT within a"worst-case scenario",i.e.start of MHT in old women with high risk for breast cancer and cardiovascular diseases,whereby only"conjugated equine estro-gens"and"medroxprogesterone acetate"have been tested.One main result was that the progestogen component is decisive for the risk of breast cancer,which according to own experimental research and observational studies may be reduced using the physiological progesterone or its isomer dydrogesterone.In addition we propose to push forward research for screening patients with increased breast cancer risk like we have done in the past decade demonstrating that certain membrane-bound receptors in breast cancer tissue or blood can increase this risk.To reduce the risk of venous thromboembolism and stroke,transdermal estradiol(gels,patches,)should be used,in free combination with progesterone or dydrogesterone as"golden standard"in patients with increased risk.To increase the compliance in our patients without special risks we mostly use the available fix-combinations of estradiol/dydrogesterone getting strong efficacy,good menstrual regulation or amenorrhea,respectively,but also other combinations may be indicated to take advantage of for example androgenic or antiandrogenic pro-gestogens.

Polycystic ovary syndrome(PCOS)is the most common endocrine and metabolic disease in women of reproduc-tive age.PCOS is characterized by ovulatory disruption,which can lead to infertility.Patients with PCOS are also more likely to have poor pregnancy outcomes.For obese women,lifestyle interventions are recommended first,which have general health benefits.For women who have difficulty changing their lifestyle,drugs for the treatment of obesity or bariatric surgery could be considered.Clomiphene citrate is the first-line medication after weight loss that has been utilized in the past.Letrozole is supplanting clomiphene as the best option for ovulation induction for now,particularly in patients with PCOS.Metformin can improve ovulation and pregnancy rates;however,it has minimal effects in terms of raising live birth rates.Second-line therapies include gonadotropins and laparoscopic ovary drilling.In vitro fertilization can be utilized as a third-line treatment for patients with PCOS who have failed ovulation induction therapy or have other infertility factors.In summary,to achieve fer-tility,patients with PCOS require standardized individualized therapy.

Objective:To investigate the effects of orlistat combined with drospirenone/ethinylestradiol tablets(DRSP/EE)on anthropometric indices,sexual hormones,hepatorenal function parameters of overweight or obese patients with polycystic ovary syndrome(PCOS).Methods:75 overweight or obese PCOS patients[body mass index(BMI)＞24 kg/m2]were recruited within the Department of Gynecological Endocrinology,Beijing Obstetrics and Gynecology Hospital,Capital Medical Uni-versity,from April 2019 to January 2020,for a prospective,randomized,open-labelled comparing study.They were numbered one by one according to the order of recruitement and randomly divided into two groups,group 1 included 50 patients,orlistat plus DRSP/EE;group 2 included 25 patients treated with DRSP/EE alone.Both groups got the same comprehensive intervention in terms of individualized,standardized managment and mon-itoring of life-style like diet and exercise.The changes of anthropometric indices,sexual hormones,hepatorenal function parameters before and after three months of treatment in the two groups were compared.Results:After three months of treatment,body weight,waist circumference(WC),hip circumference(HC)and BMI of both groups were significantly decreased(P＜0.05).The decrease of body weight,WC,HC and BMI in group 1 was significantly greater than those in group 2(P＜0.05).Free testosterone and sex hormone-binding globulin in both groups were significantly changed(P＜0.05).There was no significant difference in the hepatorenal function parameters between the two groups after three months treatment(P＞0.05).Conclusion:To our knowledge our study is the first to investigate the effects of orlistat combined with DRSP/EE in overweight or obese PCOS patients comparing with the effect of using DRSP/EE alone.Orlistat combined with DRSP/EE was better than use DRSP/EE alone in getting weight loss,which provides an evidence for the choice of rational drug use in clinical practice.

In this paper,we explored to develop a new concept of computer-and internet-based learning and training method in medicine,especially in obstetrics and gynecology,which is named as Virtual Academy of Women'Health(VA).Especially in the times of infectious disease pandemics worldwide,learning at home rather than in big lectures hall,might be necessary and practical as never before.The VA is based on worldwide knowledge in medicine—free accessible on the internet—in terms of homepages,video and audio platforms,scientific papers,medical books,and different guidelines.A collection of different video-clips in various fields of women's health can assist the student or doctor in understanding the symptoms,diagnostics,and treatment of various diseases.There are two major targets of it—one is online education,and one is testing the knowledge by simulation of clinical cases.

After more than half a century of development,the intrauterine contraception (IUD) has become a relatively mature method of contraception and treatment of gynecological diseases.This paper reviewed the development of IUDs,different types of IUDs,and some problems due to them,such as bleeding,infection,malposition,dis-location,expulsion,etc.And the causes of clinical side effects,complications,and corresponding treatments of IUDs were overviewed as well.

In recent years,with the rapid development of medical research,cancer diagnosis and treatment technology have significantly improved young cancer patient's survival rate.Anticancer therapy such as chemotherapy,radiother-apy,or hematopoietic stem cell transplantation can lead to premature ovarian insufficiency.The endocrine and reproductive function of the ovary is critical to women's physical and mental health.Ovarian tissue cryopreser-vation and transplantation can protect not only female fertility but also preserve ovarian endocrine function.This paper interprets the guidelines for ovarian tissue cryopreservation and transplantation issued by the Chinese Society of Gynecological Endocrinology affiliated to the International Society of Gynecological Endocrinology.The purpose of this guideline's interpretation is to promote more medical workers to understand the technology of ovarian tissue cryopreservation and transplantation,which can provide patients with more choices of fertility protection methods and improve their quality of life.

Objective:To explore the progress and prospect of evaluation methods for infertility patients.Methods:From September 2017 to December 2020,199 cases of infertility patients who have accepted mini-hysteroscopy examination in the Department of Gynecological Endocrinology,Beijing Obstetrics and Gynecology Hospital,Capital Medical University.The patients who had primary ovary insufficiency,tubal infertility were excluded;patients with hysteroscopy contradiction,such as acute or sub-acute vaginal tract inflammation,en-dometrium lesion or endometrium carcinoma,severe cardiovascular,liver or kidney insufficiency were excluded.40 patients were excluded and 15 patients lost follow up,144 patients were eventually included in the analysis.The patient's age,body mass index,infertility etiology,preoperative and postoperative stimulate ovulation cycle,pregnancy state and pregnancy time were recorded.The effect of mini-hysteroscopy on ovulation induction cycle was analyzed in pregnant patients.Results:The average age of 144 patients was 32.10±4.67 years old.96 (66.67％) patients were found to have intrauterine abnormalities,while 48 (33.33％) patients were found to have normal intrauterine cavity.48 cases of pregnancy,accounting for 33.33％;the median and interquartile ranges[M (Q1,Q3)]of ovulation induction cycles before and after surgery were respectively[3 (0,5)],[2 (1,3)],the difference was statistically significant(P ＜ 0.05).Among the 48 pregnant patients,32 of them had no structural lesions in hysteroscopy,the ovula-tion induction cycle of these patients before and after hysteroscopy were respectively[5 (0,9)],[1 (0,3)],the difference was statistically significant (P ＜ 0.05).Conclusion:Uterine cavity evaluation is important for the assessments of fertility.As an advanced diagnosis instrument,mini-hysteroscopy can not only timely detect the intrauterine abnormalities of patients,but also with great application value in shorten the ovulation cycle in infertility patients and increase the pregnancy rate.
