Advances in treatment of acute leukemia and long-term ovarian function in children and adolescents / 国际儿科学杂志

Acute leukemia（AL）is a common hematological malignancy in children and adolescents. Chemotherapy is currently the primary treatment for AL.Alternative therapies，such as hematopoietic stem cell transplantation（HSCT），targeted therapy，and immunotherapy also offer greater hope for the survival of refractory/relapsed patients. Chemotherapeutic drugs，radiotherapy，targeted drugs and immunotherapeutic drugs are well-applied clinically，meanwhile posing threats to non-target systems. The adverse effects on the reproductive system may lead to the dilemma of infertility，thus reducing the long-term quality of life. As the survival rate of AL patients keeps increasing continuously，the influence of different treatments on the gonad function needs to be clarified. With the help of targeted fertility prevention，the patient′s quality of life can be enhanced in parallel with life span. This article aims to review the impact of AL treatment on ovarian function in female children and adolescents and provide ideas for the long-term fertility protection of leukemia patients.

Transumbilical Single-port Laparoscopic Ovarian Cyst Excision With Protection of Ovarian Function / 中国微创外科杂志

Objective To investigate the clinical application value of transumbilical single-port laparoscopic ovarian cyst excision with protection of ovarian function.Methods From July 2018 to December 2019,we performed 56 cases of single-port laparoscopic ovarian cyst debulking,in which the umbilicus was incised transversely for about 2 cm and a single-port trocar puncture was placed to form an artificial pneumoperitoneum.The ultrasonic knife was used to avoid the ovarian hilum and cut the ovarian cortex on the opposite side of the ovary to ensure a good blood supply.The ovary on the affected side was fixed to facilitate blunt separation of the cyst and preserve the normal tissues of the ovary as much as possible.The 2-0 absorbable suture was applied for hemostasis and ovarian reconstruction.Results The operations were successfully completed in all the 56 cases,including bilateral ovarian cyst excision in 3 cases,salpingectomy in 3 cases,tubal mesangial cyst excision in 1 case,hysteromyomectomy in 2 cases,appendectomy in 1 case(an additional puncture hole was added due to the need for abdominal drainage after the operation),hysteroscopic resection of endometrial polyps in 1 case,and pelvic adhesion release in 1 case.The operation time was(72.0±30.0)min,and the postoperative hospitalization time was(5.0±0.6)d.No complication occurred.The 56 patients were followed up for 2-3 years,with an average of 1.5 years,with no complications,poor wound healing,or recurrence of ovarian cysts.There was no significant difference in the number of ovarian antral follicles between 6 and 12 months after surgery and before surgery[7.02±1.57 vs.7.05±1.55,P = 1.000;6.93±1.46 vs.7.05±1.55,P =1.000].There was no significant difference in ovarian stromal blood flow(P>0.05),indicating no decrease in ovarian function.Conclusion The key to protecting ovarian function is the rational selection of surgical instruments and incisions,precise performance of resection of ovarian cysts,and protection of ovarian blood supply.

Effects of erianin on the apoptosis of ovarian granulosa cells in rats with polycystic ovary syndrome and its mechanism / 中国药房

OBJECTIVE To investigate the effects of erianin （ERI） on the apoptosis of ovarian granulosa cells in rats with polycystic ovary syndrome （PCOS） and its mechanism. METHODS PCOS rat model was constructed by subcutaneous injection of dehydroepiandrosterone， and the successfully constructed rats were randomly divided into PCOS group， ERI low-dose， medium- dose and high-dose groups （10， 20， 40 mg/kg） and ERI high dose + verteporfin group （40 mg/kg ERI + 10 mg/kg verteporfin）， with 10 rats in each group. Another 10 normal rats were selected as the normal group. Rats in each administration group were given corresponding dose of ERI and/or intraperitoneal injection of vitiporfin， and rats in the PCOS group and normal group were orally administered an equal volume of 1% dimethyl sulfoxide， once a day， for 6 consecutive weeks. After administration， the body weight， fasting blood glucose （FPG）， serum levels of estradiol （E2）， testosterone （T）， follicle stimulating hormone （FSH） and luteinizing hormone （LH） were detected in each group； morphological changes in ovarian tissue were observed， and the apoptosis of ovarian tissue cells was analyzed. Apoptosis-associated proteins [B-cell lymphoma-2 （Bcl-2）， Bcl-2 associated X protein （Bax）， Caspase-3] and Hippo-YAP signaling pathway associated proteins [large tumor suppressor kinase 1 （LATS1）， phosphorylated LATS1 （p-LATS1） and Yes associated protein （YAP）， phosphorylated YAP （p-YAP）， transcriptional co-activator with PDZ binding motif （TAZ）] were detected in ovarian tissue. RESULTS Compared with PCOS group， the ovarian polycystic characteristics of the ERI low-dose， medium-dose，and high-dose groups were reduced， the number of atretic follicles was reduced， and the granulosa cell layer was thickened； the body mass， FPG， T， LH， LH/FSH， the number of cystic follicles， cell apoptosis index， protein expressions of Bax， Caspase-3， p-LATS1 and p-YAP were greatly decreased （P＜0.05）； the number of corpus luteum， protein expressions of E2， Bcl-2， LATS1， YAP and TAZ were greatly increased （P＜0.05）. Compared with ERI high-dose group， the above indexes in ERI high-dose + vitiporfin group were inhibited （P＜0.05）. CONCLUSIONS ERI can promote the proliferation of ovarian granulosa cells and improve the level of sex hormones in PCOS rats， and its mechanism of action may be related to the inhibition of the Hippo-YAP signaling pathway.

Clinical Efficacy of TCM Multi-channel Intervention Plus Antagonist Regimen on Ovarian Function，TCM Syndromes and Natural Conception in Poor Ovarian Responders Undergoing IVF-ET / 中国实验方剂学杂志

ObjectiveTo objectively analyze the effects of traditional Chinese Medicine （TCM） multi-channel intervention on the ovarian function，TCM syndromes and natural conception of poor ovarian responders（kidney-Yin deficiency，liver depression and blood stasis pattern） who planned to receive another in vitro fertilization embryo transfer（IVF-ET）antagonist regimen. MethodThe 128 low-prognosis patients （kidney Yin deficiency，liver depression and blood stasis pattern） who attended the West China Second University Hospital， Sichuan University and the Hospital of Chengdu University of Traditional Chinese Medicine from August 2020 to February 2023 and met the inclusion criteria were selected，and then divided into the treatment group and the control group according to the random number table，with 64 patients in each group. The control group was treated with oral dehydroepiandrosterone（DHEA），while the treatment group was treated with multi-channel TCM（oral TCM decoction + auricular point sticking + Bushen Huoxue prescription through retention enema）. After 3 menstrual cycles，the relevant indicators for ovarian function evaluation，TCM syndrome scores and natural conception were collected from both groups. ResultCompared with the situation before treatment，the basal follicle stimulating hormone（bFSH），bFSH/basal luteinizing hormone（bLH），basal estradiol（bE2），antral follicle count（AFC），the number of oocytes obtained，the number of normal fertilization，the number of superior embryos and TCM syndrome scores in the treatment group were improved after treatment（P<0.05，P<0.01）. For the control group， the bFSH/bLH and TCM syndrome scores were increased after treatment（P<0.05）， while the bFSH，bFSH/bLH，bE2，AFC，the number of oocytes obtained，the number of normal fertilization，and the number of superior embryos showed no significant difference after treatment. Compared with the control group after treatment，bFSH，bFSH/bLH，bE2，AFC，the number of normal fertilization，the number of superior embryos and TCM syndrome scores in the treatment group were better （P<0.05，P<0.01），while there was no significant difference in the number of oocytes obtained. After treatment，there were 3 cases of natural conception in the treatment group，while there were no natural conception in the control group. ConclusionFor patients with poor ovarian response and kidney Yin deficiency，liver depression and blood stasis pattern，multi-channel intervention of TCM plus the antagonist regimen can reduce bFSH，bFSH/bLH values，improve the levels of bE2，increase AFC，the number of oocytes obtained，the number of normal fertilization and the number of superior embryos，improve ovarian function，menstruation and TCM syndromes，improve their quality of life，and even enable some patients to get pregnant naturally before re-progression and improve their pregnancy outcome.

Practical Prediction Model for Ovarian Insufficiency after Radiation / Modelo prático de predição para insuficiência ovariana após radiação

Abstract Objective The present study aimed to develop a useful mathematical model that predicts the age at which premature ovarian insufficiency might occur after teletherapy radiation. A diagnosis of premature or early menopause has physical and psychological consequences, so women may need support and long-term medical follow-up. Methods To correlate ovarian radiation dose with ovarian function, we used the formula described by Wallace et al.: √g(z) = 10(2-0,15z), where "g(z)" and "z" represent oocyte survival rate and the radiation dose (in Gray), respectively. By simulating different ages and doses, we observed a pattern that could be used to simplify the relationship between radiation dose and remaining time of ovarian function. Results We obtained a linear function between ovarian radiation dose and loss of ovarian function (LOF) that is the percentage of decrease in the time to the ovarian failure compared with the time expected for a woman at the same age without irradiation exposition. For patients <40 years old and with ovarian radiation doses < 5 Gy, the equation LOF = 2.70 + (11.08 × Dose) can be applied to estimate the decrease in time to premature ovarian insufficiency. Conclusion The present study reports a practicable theoretical method to estimate the loss of ovarian function. These findings can potentially improve the management and counseling of young women patients submitted to radiotherapy during their reproductive years.

Resumo Objetivo O presente estudo teve como objetivo desenvolver um modelo matemático útil que prediz a idade na qual a insuficiência ovariana prematura pode ocorrer após a radioterapia externa (teleterapia). O diagnóstico de menopausa prematura ou precoce tem consequências físicas e psicológicas; portanto, as mulheres podem precisar de apoio e acompanhamento médico de longo prazo. Métodos Para correlacionar a dose de radiação ovariana com a função ovariana, foi usada a fórmula descrita por Wallace et al.: √g(z) = 10(2-0,15z), na qual "g(z)" e "z" representam a taxa de sobrevivência do oócito e a dose de radiação (em Gray), respectivamente. Ao simular diferentes idades e doses, observamos um padrão que poderia ser usado para simplificar a relação entre a dose de radiação e o tempo restante da função ovariana. Resultados Obtivemos uma função linear entre a dose de radiação ovariana e a perda da função ovariana (LOF, na sigla em inglês) que é a porcentagem de diminuição no tempo até a falência ovariana em relação ao tempo esperado para uma mulher da mesma idade sem exposição à radiação. Para pacientes<40 anos de idade e com doses de radiação ovariana < 5 Gy, a equação LOF = 2,70 + (11,08 × Dose) pode ser aplicada para estimar a redução no tempo até a insuficiência ovariana. Conclusão O presente estudo relata um método teórico viável para estimar a perda da função ovariana. Estes achados podem melhorar potencialmente o manejo e o aconselhamento de pacientes jovens submetidas à radioterapia durante seus anos reprodutivos.

Objective:To investigate the efficacy of gonadotropin releasing hormone agonist (GnRH-a) combined with a levonorgestrel-releasing intrauterine system (Mirena) in patients with adenomyosis and its effects on ovarian function, carbohydrate antigen (CA) 125, CA153 and carcino-embryonic antigen (CEA) expression.Methods:Seventy-eight patients with adenomyosis who received treatment from September 2017 to September 2020 in Shaoxing People's Hospital were included in this study. They were randomly divided into treatment and control groups ( n = 39/group). Patients in the control group were treated with a levonorgestrel-releasing intrauterine system. Patients in the treatment group were treated with GnRH-a, once per month in the first 3 months based on treatment with a levonorgestrel-releasing intrauterine system. After 6 months of treatment, changes in dysmenorrheal relief, menstrual volume, uterine volume, endometrial thickness, ovarian function, CA125, CA153 and CEA levels relative to before treatment were compared. Results:Visual analog scale score and pictorial blood assessment chart score in the treatment group were (1.36 ± 0.28) points and (38.98 ± 5.42) points, which were significantly lower than those in the control group [(1.78 ± 0.31) points, (63.42 ± 6.75) points, t = 6.27, 17.63, both P < 0.05). Uterine volume and endometrial thickness in the treatment group were (209.74 ± 15.65) cm 3 and (7.37 ± 0.57) mm, respectively, which were significantly lower than those in the control group [(278.39 ± 20.90) cm 3, (8.63 ± 0.86) mm, t = 16.45, 7.62, P < 0.05]. There were no significant differences in serum levels of luteinizing hormone, follicle stimulating hormone and estradiol between the two groups (all P > 0.05). Serum CA125, CA153 and CEA levels in the treatment group were (26.87 ± 7.21) U/L, (23.12 ± 7.38) U/mL and (5.45 ± 0.96) μg/L, respectively, which were significantly lower than those in the control group [(49.93 ± 8.97) U/L, (38.94 ± 6.21) U/mL, (8.23 ± 1.35) μg/L, t = 12.51,10.24,10.48, P < 0.05]. Conclusion:GnRH-a combined with a levonorgestrel-releasing intrauterine system (Mirena) can markedly relieve dysmenorrhea, reduce menstrual volume, uterine volume, and endometrial thickness, has no obvious effects on ovarian function, and greatly reduce the levels of CA125, CA153 and CEA. Therefore, the combined method is a safe and effective non-surgical treatment method of adenomyosis.

Preliminary exploration of the relationship between the serum anti-Müllerian hormone and the related clinical factors / 中华核医学与分子影像杂志

Objective:To explore the relationship between serum anti-Müllerian hormone (AMH) level and related clinical factors in healthy females, and establish and validate equation of correlation between age and serum AMH level for healthy females.Methods:From March 2015 to December 2016, a total of 602 females who measured serum AMH level in Department of Nuclear Medicine, the Second Affiliated Hospital of Soochow University were retrospectively enrolled. All cases had relatively complete clinical data, and were divided into healthy group (484 cases, 20-52 years) and case group (118 cases, 20-42 years; patients with menstrual disorders). Relationships between serum AMH level and estradiol (E2), tesosterone (T), follicle stimulating hormone (FSH), luetinizing hormone (LH), body mass index (BMI) of healthy group were analyzed by Spearman rank correlation. Kruskal-Wallis rank sum test was used to analyze the relationship between history of gestation and serum AMH level. Serum AMH level of health group was processed to establish predictive equation for serum AMH level. Internal ( n=27) and external ( n=37) validation group were chosen from healthy females with serum AMH level measured to validate the equation, and signed rank test was used to analyze the data. Difference between serum AMH level in case group and healthy group with corresponding age was explored by independent-sample t test. Results:Serum AMH levels were positively correlated with E2 and T ( rs values: 0.263, 0.334, both P<0.001), and negatively correlated with FSH, LH, BMI ( rs values: from -0.515 to -0.110, all P<0.005). Predictive equation was established as LogAMH=-1.208+ 0.1×age-0.000 042×age 3 ( R2=0.735, P<0.001). No statistically significant difference was found between real serum AMH levels and calculated serum AMH levels in the internal and external validation groups ( z values: -1.62 and -1.52, both P>0.05). Females in case group ( n=118) and control group ( n=446) were divided into two sub-groups respectively (<35 years and ≥35 years), and serum AMH levels of case group were lower than those of control group with corresponding age ( t values: 18.64, 11.70, both P<0.001). Conclusions:In healthy females, serum AMH level is related to some clinical data. The equation between serum AMH level and age established in the study may provide reference for clinical diagnosis and treatment.

The Importance of Education regarding the Effects of Anticancer Treatment on Fertility and Ovarian Function in the Female Patients with Breast Cancer

OBJECTIVES: Female breast cancer patients generally have limited knowledge regarding issues related to preservation of ovarian function and fertility. The present study aimed to explore the change in the understanding of these issues when female breast cancer patients are educated and counseled about ovarian function and fertility after anticancer treatment.METHODS: One hundred nine young female breast cancer patients completed a questionnaire, which revealed their thoughts and opinions before and after receiving the education about ovarian function and fertility. Their responses were analyzed to determine the impact of the education on their perception and understanding of the aforementioned issues.RESULTS: The objective survey had four main themes: planning and desire for children, degree of baseline understanding of the effects of anticancer therapy on fertility and ovarian function, resultant change in cognition after education about cancer treatment and its relationship with fertility, and need for education regarding the types of therapies received and their effects on subsequent ovarian function and fertility before treatment.CONCLUSIONS: The preservation of ovarian function and fertility is an important factor that must be included in the discussion prior to initiation of anticancer therapy. Although the study results do not have high educational effectiveness or a high satisfaction with education, there is a need for information and education regarding the impact of anticancer treatment on preservation of ovarian function and fertility.

Effect of radiotherapy on ovarian function in patients undergoing radical surgery for cervical cancer / 中华放射肿瘤学杂志

Objective The correlation between dosimetric parameters of transposed ovary and different clinical ovarian functional status was assessed in young patients with cervical cancer who needed adjuvant radiotherapy after radical resection of the Ⅰ B1-Ⅱ A2 phase of preserved and transposed ovaries.Methods The function of transposed ovary and relevant clinical symptoms in 86 patients before and 2 years after treatment between 2015 and 2017 were retrospectively analyzed,and the correlation between the dosimetric parameters and functional status of transposed ovaries during radiotherapy was evaluated.Different in vitro measures were adopted to protect the transposed ovaries during postoperative radiotherapy including 68 cases of IMRT or VMAT and 18 cases of two-dimensional and other central radiotherapy.Results The nearest distance between ovary and PTV was negatively correlated with the ovarian dose ≥ V5 Gy (P=0.025).Vs Gy and D were positively correlated with FSH after treatment (P=0.011,0.020).The larger the volume of Vs Gy and the large D the higher the FSH,the worse the ovarian function.In two-dimensional technology,the ovarian dose ≥ V5 Gy was significantly lower than that in three-dimensional technique.The average age of those with normal ovarian function after treatment was 33.4 years,whereas the average age of women with ovarian failure was 39.6 years (P=0.007).The number of preserved ovaries and whether synchronous chemotherapy was delivered were similar in patients with different ovarian status,which were correlated with the levels of FSH and E2 (Estradiol) before treatment,that is,the higher the level of FSH before treatment,the lower the E2 of ovarian FSH after treatment,and the higher the level of FSH after treatment,the lower the level of ovarian E2.Patients who retained their ovaries before treatment but suffered from ovarian failure received neoadjuvant chemotherapy with a slightly higher age.Conclusions Age,V8 Gy and D of the transposed ovary,the shortest distance between transposed ovary and PTV,whether neoadjuvant chemotherapy was delivered before surgery and radiotherapy technique affect the protection of the function of transposed ovary.

Objective@#The correlation between dosimetric parameters of transposed ovary and different clinical ovarian functional status was assessed in young patients with cervical cancer who needed adjuvant radiotherapy after radical resection of the ⅠB1-ⅡA2 phase of preserved and transposed ovaries.@*Methods@#The function of transposed ovary and relevant clinical symptoms in 86 patients before and 2 years after treatment between 2015 and 2017 were retrospectively analyzed, and the correlation between the dosimetric parameters and functional status of transposed ovaries during radiotherapy was evaluated. Different in vitro measures were adopted to protect the transposed ovaries during postoperative radiotherapy including 68 cases of IMRT or VMAT and 18 cases of two-dimensional and other central radiotherapy.@*Results@#The nearest distance between ovary and PTV was negatively correlated with the ovarian dose ≥V5 Gy (P=0.025). V8 Gy and Dmean were positively correlated with FSH after treatment (P=0.011, 0.020). The larger the volume of V8 Gy and the large Dmean, the higher the FSH, the worse the ovarian function. In two-dimensional technology, the ovarian dose ≥V5 Gy was significantly lower than that in three-dimensional technique. The average age of those with normal ovarian function after treatment was 33.4 years, whereas the average age of women with ovarian failure was 39.6 years (P=0.007). The number of preserved ovaries and whether synchronous chemotherapy was delivered were similar in patients with different ovarian status, which were correlated with the levels of FSH and E2 (Estradiol) before treatment, that is, the higher the level of FSH before treatment, the lower the E2 of ovarian FSH after treatment, and the higher the level of FSH after treatment, the lower the level of ovarian E2. Patients who retained their ovaries before treatment but suffered from ovarian failure received neoadjuvant chemotherapy with a slightly higher age.@*Conclusions@#Age, V8 Gy and Dmean of the transposed ovary, the shortest distance between transposed ovary and PTV, whether neoadjuvant chemotherapy was delivered before surgery and radiotherapy technique affect the protection of the function of transposed ovary.

Effect of pituitrin-water separation in laparoscopic removal of ovarian chocolate cyst and its effect on ovarian function / 中国基层医药

Objective To investigate the effect of pituitrin-water separation on hemoglobin and ovarian func-tion in laparoscopic ovarian chocolate cyst removal.Methods From February 2018 to February 2019,82 patients with ovarian chocolate cyst removed by laparoscopy were selected from the Second Affiliated Hospital of Wenzhou Medical University.They were randomly divided into observation group and control group according to the digital table,with 41 cases in each group.The control group underwent traditional laparoscopic tear-and-tear ovarian cyst removal,while the observation group underwent pituitrin-water separation.The changes of perioperative indicators ,the decrease of hemoglobin (Hb) before and after operation ,the positive rate of normal ovarian tissue on cyst wall and the number of normal follicles attached to cyst wall ,the changes of serum hormone levels before and after operation were compared between the two groups.Results The amount of bleeding during operation in the observation group [(58.97 ±8.74)mL] was less than that in the control group [(118.93 ±24.21)mL],and the operation time in the observation group[(57.46 ±8.27) min] was shorter than that in the control group [(87.38 ±10.19) min] ,the differences were ststistically significant between the two group ( t ＝14.916,14.598,all P ＜0.05 ).There was no statistically significant difference in the time of anal exhaust between the two groups (P＞0.05).The decrease of Hb in the observation group [(0.71 ±0.16)g／L] was lower than that in the control group [(1.27 ±0.35) g／L] ( t＝9.318,P＜0.05).The positive rate of normal ovarian tissue on cyst wall in the observation group (21.95%) was lower than that in the control group (56.10%),the number of normal follicles attached to the cyst wall in the obser-vation group (2.65 ±0.49) was less than that in the control group (4.86 ±1.24) ,the differences were ststistically significant between the two group ( χ2 ＝10.045, t ＝10.613, all P ＜0.05).The serum level of E2 [( 398.21 ± 17.84)pmol／L] in the observation group was higher than that in the control group [(367.83 ±15.21) pmol／L], while FSH [(6.72 ±0.28)mIU／mL] and LH [(5.23 ±0.38)mIU／mL] levels in the observation group were lower than those in the control group [(7.19 ±0.35)mIU／mL and (5.69 ±0.31)mIU／mL],the differences were ststisti-cally significant between the two group (t＝8.298,6.714,6.006,all P＜0.05).Conclusion The method of pitui-trin-water separation is effective in laparoscopic ovarian chocolate cyst removal ,which can reduce the injury during operation,has little effect on hemoglobin and improve the ovarian reserve function of patients .

Efficacy of gonadotropin-releasing hormone analogues in protecting ovarian function of premenopausal breast cancer patients undergoing chemotherapy: A meta-analysis / 肿瘤

Objective: To evaluate the therapeutic efficacy of gonadotropin-releasing hormone analogues (GnRHa) in protecting ovarian function of premenopausal breast cancer patients undergoing chemotherapy. Methods: The randomized controlled trials of GnRHa protecting ovarian function of premenopausal breast cancer patients undergoing chemotherapy were collected from PubMed, Cochrane Library, EMbase, China National Knowledge Infrastructure (CNKI) and Wanfang Databases, and the date range was from the establishment of the databases to March 2018. According to the inclusion and exclusion criteria, the literatures about amenorrhea rate, premature ovarian failure (POF) rate, menstrual recurrence rate, pregnancy rate, follicle-stimulating hormone (FSH) and luteinizing hormone (LH) levels in premenopausal breast cancer patients after chemotherapy combined with GnRHa or chemotherapy alone were screened out. The outcome measurements were odds ratio (OR) and 95% confidence interval (CI). The Meta-analysis was performed using RevMan 5.3 software. Results: A total of 17 randomized controlled trials involving 1 590 patients were included in this Metaanalysis. As compared with chemotherapy alone, the chemotherapy combined with GnRHa increased the amenorrhea rate during chemotherapy (OR = 11.14, 95% CI: 4.83-25.72, P < 0.000 01), reduced the POF rate (OR = 0.35, 95% CI: 0.25-0.50, P < 0.000 01), while improved the menstrual recurrence rate (OR = 2.90, 95% CI: 1.88-4.49, P < 0.000 01) and pregnancy rate (OR = 1.81, 95% CI: 1.08-3.02, P = 0.02). Moreover, three studies showed that the levels of FSH and LH in chemotherapy combined with GnRHa group were lower than those in chemotherapy alone group, and there were significant differences in two studies (both P < 0.01). Conclusion: Chemotherapy combined with GnRHa can increase the menstrual recurrence rate and pregnancy rate of premenopausal breast cancer patients after chemotherapy, suggesting that GnRHa has a protective effect on ovarian function of those patients.

Effect of Huoxue-Xiaozheng decoction on ovarian function and mifepristone on the patients with uterine leiomyoma after operation / 国际中医中药杂志

Objective To investigate the effect of Huoxue-Xiaozheng decoction on ovarian function and mifepristone of in patients with uterine leiomyoma after operation.Methods A total of 90 patients with uterine leiomyoma after operation were divided into the observation group and control group according to random number table method,with 45 cases in each group.The control group were treated with mifepristone,and the observation group with Huoxue-Xiaozheng decoction on the basis of the control group.The serum sex hormone (FSH,LH,E2,P and T),cell factor (TGF-β3,IL-22,FSH,LH,E2,P and T) and the uterine volume between two groups after treatment were compared,and the recurrence rate of uterine leiomyoma was compared between the two groups after treatment.Results After treatment,the serum sex hormone FSH (17.11 ± 4.01 μg/L vs.20.16 ± 5.21 μg/L,t=3.112),LH (16.78 ± 3.34 μg/L vs.19.52 ± 4.32 μg/L,t=3.366),E2 (156.60 ± 46.32 pmol/L vs.220.31 ± 50.11 pmol/L,t=6.263),P (8.37 ± 2.50 μg/L vs.15.23 ± 2.45 μg/L,t=13.1467),T (0.23 ± 0.05 ng/ml vs.0.31± 0.06 ng/ml,t=6.8712),cell factor TGF-β3 (22.08 ± 4.34 μg/L vs.28.10 ± 5.02 μg/L,t=6.086) of the observation group were significantly lower than those of the control group (P＜0.01).After treatment,the uterine volume (85.42 ± 19.35 cm3 vs.97.37 ± 20.45 cm3,t=2.847) of the observation group was significantly lower than that of the control group (P＜0.01).After 2 years of follow-up,the uterine fibroids overall recurrence rate of the observation group was 13.3％ (6/45),while the control group was 31.1％ (14/45),.The difference between two groups,was statistically significant (x2=4.114,P=0.043).Conclusions The Huoxue-Xiaozheng decoction combined with mifepristone can effectively inhibit the secretion of ovarian hormones and decrease the expression of TGF-β3,IL-22,FSH,LH,E2,P and T in patients with uterine leiomyoma.

Summary and expectation of the role of GnRHa in the treatment of breast cancer / 中华肿瘤杂志

Gonadotropin-releasing-hormone analogues (GnRHa) are widely used in the treatment of premenopausal breast cancer. The anti-tumor effect of GnRHa is similar to that of surgical castration or chemotherapy, through reversibly inhibiting ovarian function and downregulating the estrogen level in premenopausal female. At the same time, GnRHa can protect the ovarian function, avoiding premature ovarian failure. Also GnRHa can reduce the breast density and endometrial thickness, as a result of which GnRHa may be used to prevent breast cancer in the higher risk population and promote quality of life in breast cancer patients. We here review the clinical roles and research progress of GnRHa in breast cancer.
