Abstract
Patients with locally advanced rectal cancer who undergo neoadjuvant chemoradiotherapy may achieve pathological complete response (pCR). The incidence of recurrence is low among patients with pCR, there is still a lack of consensus on postoperative treatment and follow-up strategy. This review summarizes the recurrence patterns of patients with pCR, including distant metastasis rate, characteristics of distant metastasis time and location, local recurrence rate, and local recurrence time. The aim is to provide reference for the postoperative treatment and follow-up strategy of patients with pCR. Patients with pCR have a low recurrence rate, with infrequent local recurrence. Distant metastasis is the most common recurrence pattern, primarily in the lung and secondly in the regional lymph node. The time of recurrence is delayed which suggests the need for appropriate adjustments to follow-up strategy, extending the follow-up period, and placing emphasis on monitoring sites prone to recurrence.

Abstract
Background Several studies have compared the effects of fixed and flexible gonadotropin releasing hormone antagonist (GnRH-ant) protocols during in vitro fertilization and embryo transfer (IVF-ET). However, which GnRH-ant initiation strategy is better remains controversial. Moreover, no studies have assessed the optimal timing of GnRH-ant initiation in women of advanced maternal age (AMA). Methods In this retrospective cohort study, a total of 472 infertile women aged ≥ 35 years old undergoing their first IVF cycle from August 2015 to September 2021 at a tertiary academic medical center were recruited, of whom 136 followed fixed GnRH-ant protocol and 336 followed flexible GnRH-ant protocol. The primary outcomes measured were the cumulative live birth rate (CLBR) per IVF cycle and the time to live birth (TTLB) from the date of oocyte retrieval. Cox proportional models were used to calculate the hazard ratio (HR) and 95% confidence interval (CI) of CLBR regarding GnRH-ant timing. Results No significant difference in CLBR was found between the fixed and flexible GnRH-ant groups (27.9% vs 20.5%, p=0.105). The TTLB was also comparable between groups (10.56 vs 10.30 months, p=0.782). The Kaplan-Meier analysis for CLBR also showed comparable results between groups (P=0.351, HR=0.83; 95%CI: 0.56-1.23). After establishing a multiple Cox proportional hazard model, the fixed GnRH-ant group still had comparable CLBR with the flexible GnRH-ant group (HR=0.85; 95%CI: 0.53-1.38; P=0.518). Subgroup and sensitivity analyses also demonstrated similar results. Conclusion GnRH-ant protocols can be tailored to the needs of AMA women, and timing of GnRH-ant initiation can be adjusted flexibly.

Abstract
BackgroundThe use of frozen embryo transfer (FET) has grown exponentially over the past few years. However, in clinical practice, there are no specific criteria as to whether a delay of at least one menstrual cycle is required for an FET after a failed fresh ET or a freeze-all cycle.ObjectiveThrough the effects on live birth rate (LBR), clinical pregnancy rate (CPR) and pregnancy loss rate (PLR), to determine whether FET requires a delay of at least one menstrual cycle after fresh ET failure or a freeze-all cycle.MethodsThe search was conducted through PubMed, Web of Science, CNKI, and Wanfang databases for terms related to FET timing as of April 2023. There are no restrictions on the year of publication or follow-up time. Women aged 20 to 46 with any indication for in vitro fertilization and embryo transfer (IVF-ET) treatment are eligible for inclusion. Oocyte donation studies are excluded. Except for the case report, study protocol, and abstract, all original studies are included.ResultsIn 4,124 search results, 19 studies were included in the review. The meta-analysis includes studies on the adjusted odds ratio (OR) and 95% confidence interval (CI) of reported live birth rate (LBR), clinical pregnancy rate (CPR), and pregnancy loss rate (PLR), 17 studies were retrospective cohort study, and 2 studies were randomized controlled trial, a total of 6,917 immediate FET cycles and 16,105 delayed FET cycles were involved. In this meta-analysis, the combined OR of LBR was [OR = 1.09, 95% CI (0.93–1.28)], the combined OR of CPR was [OR = 1.05, 95% CI (0.92–1.20)], and the combined OR of PLR was (OR = 0.96, 95% CI 0.75–1.22). There was no statistical significance between the two groups.ConclusionOverall, delaying FET by at least one menstrual cycle has no advantage in LBR, CPR, or PLR. So, flexible scheduling of FETs is available to both doctors and patients.Systematic review registrationhttps://www.crd.york.ac.uk/PROSPERO/, identifier CRD42020161648.

Abstract
Objective There is no clear evidence of clinical significance of endometrial compaction, which can be measured by a reduction in endometrial thickness (EMT) during the follicular-luteal transition before the day of embryo transfer. In this study, we aim to determine whether endometrial compaction has an effect on in vitro fertilization (IVF) success. Methods We searched PubMed, Cochrane, Embase, and Web of Science electronic databases for studies published in English up to March 2023. Heterogeneity between studies was assessed using the I2 statistic. The random effects model and fixed effects model was used to pool the risk ratio (RR) with a corresponding 95% confidence interval (CI). A subgroup analysis was performed based on different methods of ultrasonic measurement and different endometrial compaction rates (ECR). Stata 17.0 software was used for meta-analysis. Pregnancy outcomes, which included clinical pregnancy rate, ongoing pregnancy rate, live birth rate, and spontaneous abortion rate, were evaluated. Results In this study, 18 cohort studies were included, involving 16,164 embryo transfer cycles. Pooled results indicated that there was no significant difference between the endometrial compaction group and the non-compaction group in terms of clinical pregnancy rate (RR [95% CI]=0.98 [0.90,1.08]; I2 = 69.76%), ongoing pregnancy rate (RR [95% CI]=1.18 [0.95,1.47]; I2 = 78.77%), live birth rate (RR [95% CI]= 0.97 [0.92,1.02]; I2 = 0.00%) or spontaneous abortion rate (RR [95% CI]= 1.07[0.97,1.26]; I2 = 0.00%). According to the subgroup analysis of ultrasonic measurement methods, in the transvaginal ultrasound (TVUS) combined with abdominal ultrasonography (AUS) cycles of the endometrial compaction group, the rate of ongoing pregnancy (RR [95% CI] = 1.69 [1.26, 2.26]; I2 = 29.27%) and live birth (RR [95% CI] = 1.27 [1.00,1.61]; I2 = 62.28%) was significantly higher than that of the non-compaction group. Additionally, subgroup analysis based on ECR revealed a significantly higher rate of ongoing pregnancy when ECR ≥ 15% (RR [95% CI] = 1.99 [1.61, 2.47]; I2 = 0.00%). Conclusion Endometrial compaction has no adverse effect on clinical pregnancy rate, ongoing pregnancy rate, live birth rate, or spontaneous abortion rate. A possible explanation for the contradictory findings of previous studies lies in the method by which the EMT is measured.

Abstract
Rationale Idiopathic hypogonadotropic hypogonadism (IHH) is a prevalent congenital genetic disorder with multiple inheritance patterns. IHH can manifest as normal hypogonadotrophic sexual hypofunction (nIHH) or with an abnormal sense of smell, known as Kallmann. It primarily affects the production and effectiveness of gonadotropin-releasing-hormone (GnRh), leading to reduced follicle-stimulating hormone and luteinizing hormone levels. This results in infertility and underdeveloped secondary sexual characteristics. Patient Concerns A 29-year-old female presented with infertility. Diagnosis IHH diagnosis was confirmed through magnetic resonance (MR) scan, endocrine tests, physical examination, and B ultrasonic inspection. Additionally, genetic studies, including chromosome analysis, were conducted for the patient. The results confirmed no genetic abnormalities or concerns. Interventions The patient underwent multiple ovulation induction programs. Outcome After several ovulation induction cycles, the patient conceived and delivered a live baby. Lessons For IHH patients, a tailored human menopausal gonadotropin (HMG) dose is recommended. High-dose HMG can benefit those with poor follicular response. The addition of letrozole (5-7.5mg) may enhance follicular response during stimulation. Our approach, which emphasizes the combined use of high-dose HMG, letrozole, and the adjustment of FSH and LH ratios, offers a unique perspective compared to traditional treatments. If HMG treatment is ineffective, alternative ovulation induction methods, such as r-fsh combined with r-lh or HMG combined with rLH, can be considered. Adjusting the FSH and LH ratio and varying rFSH and rLH additions might help achieve dominant follicles and live birth in resistant cases. This case report underscores the potential benefits of our regimen, suggesting its consideration for future research and clinical applications.

Abstract
Objective To evaluate whether dual trigger could improve reproductive outcomes in women with low oocyte maturation rates compare to human chorionic gonadotropin (hCG) trigger. Methods This study included expected normal ovarian responders younger than 40 years old whose immature oocyte rate in the previous cycle was more than 50% at the reproductive center from July 2021 to November 2022. A total of 73 patients were enrolled at trigger, including 34 in the hCG trigger group and 39 in the dual trigger group (co-administration of gonadotrophin releasing hormone (GnRH) agonist and hCG, 40 and 34 h prior to oocyte retrieval, respectively). The primary outcome was oocyte maturation rate. Results There was no significant difference in the number of oocytes retrieved between the two study groups, but the oocyte maturation rate was higher in dual trigger group (84.0% [14.0%] vs. 55.5% [19.8%], p < 0.001). Moreover, there were also higher cumulative pregnancy rate (69.4% vs. 40.0%, p = 0.035) and cumulative live birth rate (66.7% vs. 36.0%, p = 0.022) in dual trigger group. Conclusion For normal responders with low oocyte maturation rates, the dual trigger may be more effective than the conventional hCG trigger.

Abstract
BACKGROUND Age-related diminished ovarian reserve (DOR) is not absolute. Some advanced maternal age (AMA) still have normal ovarian reserve (NOR) and often show better pregnancy outcomes. Exploring the transcriptomic profile of granulosa cells (GCs) in AMA could lead to new ideas for mitigating age-related diminished ovarian reserve. AIM This study aimed to analyze the transcriptomic profile of GCs in AMA with different ovarian reserve. RESULTS In total, 6273 statistically significant differential expression genes (DEGs) (|log2fc|> 1, q < 0.05) were screened from the two groups, among which 3436 genes were upregulated, and 2837 genes were downregulated in the DOR group. Through Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis, the potential functions of dysregulated genes in AMA with DOR or NOR were predicted. The GO enrichment analysis revealed that the DEGs were mainly enriched in obsolete oxidation-reduction process, mitochondrion, metal ion binding, ATP binding, etc. The KEGG pathway enrichment analysis revealed that the above-mentioned DEGs were mainly enriched in ferroptosis, regulation of actin cytoskeleton, oxidative phosphorylation, etc. Meanwhile, verification of the mRNA expression levels of DEGs revealed the possible involvement of "ferroptosis" in age-related diminished ovarian reserve. CONCLUSIONS From a new clinical perspective, we presented the first data showing the transcriptomic profile in GCs between AMA with different ovarian reserve. At the same time, we identified the role of ferroptosis in the GCs of AMA, providing a new biological basis for studying ovarian aging and improving pregnancy outcomes of AMA.

Abstract
Objective: To compare the clinical efficacy of single/double 125I-seed strands combined with biliary stents in the treatment of malignant obstructive jaundice. Methods: Totally 67 cases of patients with malignant obstructive jaundice who received single/double125I-seed strands combined with biliary stents implantation from September 2018 to December 2021 were analyzed retrospectively. Among them, 36 patients received single 125I-seed strands combined with biliary stents (single strand group) and 31 patients received double 125I-seed strands combined with biliary stents(double strands group). The technical success rate, clinical success rate, complications, biochemical and tumor indexes at 8 weeks after operation [total bilirubin (TB), direct bilirubin (DB), alanine transaminase (ALT), aspartate transaminase (AST), carbohydrate antigen 19-9 (CA19-9)], stent patency time (SP), median progression-free survival time (mPFS) and median survival time (mOS) were analyzed. Results: There was no significant difference (P>0.05) in technical success rate (100% vs 100%), clinical success rate (97.2% vs 96.8%) and major complications (5.6% vs 6.5%) between single strand group and double strands group. There were significant differences in TB, DB, ALT, AST and CA19-9 indicators between the two groups before and 8 weeks after operation (all P<0.05), but there was no significant difference in the difference value of preoperative and postoperative 8-week indicators between the two groups (all P>0.05).The SP and mPFS of double-stranded stents were longer than those of single-stranded stents.[8.6 months (95%CI:6.9-10.4) vs 6.2 months (95%CI:5.8-6.6), 3.2 months (95%CI:3.0-3.4) vs 3.0 months (95%CI:2.9-3.1), all P<0.05]. The mOS of single and double strands groups was 11.2 months (95%CI:8.3-14.1) and 13.4 months (95%CI:9.9-16.9) respectively, with no statistical difference (P=0.137). Conclusion: Compared with single 125I-seed strands, double 125I-seed strands can prolong biliary SP and mPFS, but the long-term survival index still needs further observation.

Abstract
INTRODUCTION Women characterised by diminished ovarian reserve are considered to have poor ovarian response (POR) according to Patient-Oriented Strategies Encompassing IndividualizeD Oocyte Number (POSEIDON) criteria. Patients in this population often have a poor prognosis for treatment with assisted reproductive technology. In previous studies, oestrogen pretreatment before ovarian stimulation has been shown to have a beneficial effect. However, recent studies presented conflicting conclusions. This study aims to evaluate the effectiveness of oestrogen pretreatment in patients with expected POR (POSEIDON groups 3 and 4) undergoing gonadotrophin releasing hormone antagonist (GnRH-ant) protocol. METHODS AND ANALYSIS A prospective superiority randomised parallel controlled trial will be conducted at a tertiary university-affiliated hospital. A total of 316 patients will be randomly divided into two groups at a ratio of 1:1. In the intervention group, oral oestrogen pretreatment will be administered from day 7 after ovulation until day 2 of the next menstrual cycle. Afterwards, a flexible GnRH-ant protocol will be initiated. The control group will receive no additional intervention beyond routine ovarian stimulation. The primary outcome is the number of oocytes retrieved.

Abstract
INTRODUCTION Advanced age is one of the primary risk factors for infertility. Poor ovarian response (POR) to exogenous gonadotropin is a prominent characteristic of advanced-age women undergoing in vitro fertilization and embryo transfer (IVF-ET), which results in fewer retrieved oocytes and poor pregnancy outcomes. Traditional Chinese medicine (TCM) has been shown to improve female fertility. Erzhi Tiangui (EZTG) formula, in the form of granules with 10 herbal ingredients, demonstrated potential benefits in improving oocyte and embryo quality and ovarian reserve. Thus, this study aims to evaluate the efficacy and safety of EZTG formula. METHOD The study is a multicenter, double-blind, placebo-controlled, randomized controlled trial (RCT), which will be conducted at 10 reproductive centers of tertiary hospitals. This study will enroll 480 women with expected POR of advanced age (≥35 years old) who fulfill the 2011 Bologna criteria. Participants will be assigned to either the EZTG group or the placebo group at random in an equal ratio. Each individual will receive conventional IVF-ET with EZTG granules or placebo as a complementary treatment. The primary outcome is the number of oocytes retrieved. Adverse events and safety assessments will be also conducted. DISCUSSION This study aims to provide robust evidence of the efficacy and safety of EZTG formula as a complementary treatment for advanced-age women with expected POR undergoing IVF-ET.

Abstract
Objective: To analyze the recurrence pattern of rectal cancer patients with radical surgery after neoadjuvant chemoradiotherapy. Methods: The clinicopathological characteristics and follow-up information of rectal cancer patients with radical surgery after neoadjuvant chemoradiotherapy in the Cancer Hospital of the Chinese Academy of Medical Sciences from June 2004 to December 2017 were retrospectively collected. The recurrence pattern including the time and site was investigated. Results: The age of 537 patients was (55.5±11.7) years, of whom 361 were male (67.2%). The median follow-up time [M(Q1,Q3)] was 77.9 (64.5, 95.6) months. Moreover, 30.7% (165/537) of patients had distant metastasis or local recurrence; 26.8% (144/537) of patients had distant metastasis; 5.6% (30/537) of patients had local recurrence; 1.7% (9/537) of patients had both distant metastasis and local recurrence. In all the recurrent patients, 23.6% (39/165) were in the first year after surgery, followed by 27.3% (45/165) in the second year, 17.0% (28/165) in the third year, and 15.8% (26/165) after five years. According to the risk curve drawn by the life table, the highest metastasis risk of patients occurred in the second year after surgery, and the metastasis risk peak occurred again after more than five years. The lung was the most common metastatic organ, accounting for 47.9% (69/144), followed by the liver (18.8%, 27/144). The ratios of the recurrent patients in each ypTNM stage were 9.5% (8/84), 12.0% (12/100), 26.5% (41/155), 52.5% (104/198), respectively. The proportion of recurrent patients in tumor regression grade (TRG) 1-2 and TRG 3-5 patients were 19.2% (38/198) and 37.5% (127/339), respectively. Conclusions: The recurrence pattern of patients undergoing radical surgery after neoadjuvant chemoradiotherapy is mainly distant metastasis. The lung is the primary metastatic organ. The risk of distant metastasis and local recurrence is high in the first three years after surgery, and there is still high risk of recurrence after five years. For patients with ypTNM stage 2, 3 and TRG3-5, the postoperative adjuvant chemotherapy and long-term follow-up should be strengthened.

Abstract
Objective: To analyze the clinicopathological factors affecting long-term disease-free survival and the characteristics of local recurrence or distance metastasis of rectal cancer patients with complete pathological response after neoadjuvant chemoradiotherapy. Methods: The clinicopathological data and follow-up information of patients with a complete pathological response of rectal cancer after neoadjuvant chemoradiotherapy in the Cancer Hospital of Chinese Academy of Medical Sciences from June 2004 to December 2019 were retrospectively collected. The clinicopathological factors affecting the long-term disease-free survival of patients were analyzed to build a prediction model of local recurrence and distant metastasis and to evaluate the benefits of postoperative chemotherapy. Results: The age of 108 patients was(56.3±11.6) years, of which 68 were males (63.0%); The median follow-up time was 79.9 (61.8, 112.6) months. There were 12 patients (11.1%) who had a local recurrence or distant metastasis. The 5-year disease-free survival rate was 91.1% with 9 patients who experienced recurrence. Multivariate Cox proportional hazards regression analysis showed that the maximum diameter of the residual tumor or scar (HR=8.41, 95%CI: 1.08-65.22, P=0.042) and the distance from the lower edge of the tumor to the anal margin before treatment (HR=4.54, 95%CI: 1.23-16.81, P=0.023) were independent risk factors affecting the prognosis. The prognosis of patients was stratified based on relevant factors. The 5-year cumulative disease-free survival rate of those patients receiving postoperative standardized chemotherapy was 92.0%, while for patients who did not receive or complete standardized chemotherapy, the 5-year cumulative disease-free survival rate was 82.3%. Conclusions: The maximum diameter of the residual tumor or scar and the distance from the lower edge of the tumor to the anal margin before treatment were independent risk factors affecting the prognosis of patients with a complete pathological response. Patients with independent risk factors could benefit from the standardized postoperative chemotherapy.

Abstract
Background Gonadotropin-releasing hormone antagonists (GnRH-ant) are widely used in current in vitro fertilization-embryo transfer (IVF-ET), however, whether the lowest daily dose of GnRH-ant is individualized remains unknown. Due to the negative effect of GnRH-ant on endometrial receptivity, lessening the amount of GnRH-antagonists used during controlled ovarian stimulation may be helpful for embryo implantation. As such, a randomized controlled study is essential to validate the feasibility and efficacy of daily GnRH-ant dose reduction to 0.125 mg geared towards providing scientific evidence for guidance in clinical practice. Methods In total, 620 infertile women undergoing in vitro fertilization will be enrolled in the multicentered, randomized, parallel controlled trial. Based on a computer-generated random list, they will be randomly and equally subdivided into half-dose GnRH-ant group or conventional-dose GnRH-ant group. The primary outcome is ongoing pregnancy ie, intrauterine pregnancy diagnosed by pelvic ultrasonography at more than 12 weeks of gestation accompanied by normal fetal heartbeats. Secondary outcomes include cycle cancellation, premature luteinizing hormone surge, positive pregnancy, embryo implantation rate, clinical pregnancy, early spontaneous abortion, and live birth. The intention-to-treat and per protocol analyses will be used to initially analyze the difference in ongoing pregnancy rate between the two groups, while the multiple imputation method was used to handle missing values in the data. Discussion At present, no randomized controlled trials (RCTs) have been performed on the use of the half-dose GnRH-ant protocol (0.125mg/d) to improve reproductive outcomes of IVF-ET in predicted normal responder, compared to conventional-dose GnRH-ant protocol (0.25mg/d). Half-dose GnRH-ant protocol might provide a suitable clinical solution for predicted normal responder undergoing IVF treatment. Thus, it is critical to conduct a well-designed RCT to evaluate the impact of a half-dose GnRH-ant protocol on the reproductive outcomes of IVF-ET in predicted normal responder. Trial Registration This study was registered in the Chinese Clinical Trials Registry Platform on August 29, 2020. (chictr.org.cn; identifier: ChiCTR2000037629). This trial is version 1.3.

Abstract
BACKGROUND Exposure of the female reproductive tract to either seminal plasma or fluid component of the ejaculate is beneficial to achieving successful embryo implantation and normal embryo development. But whether the "physical" component of sexual intercourse during the peri-transfer period have any influence on frozen-thawed embryo transfer (FET) pregnancy outcomes is not clear. METHODS We conducted a randomized trial that included 223 patients undergoing in vitro fertilization (IVF) treatment at a university-affiliated reproductive center from 19 July 2018 to 24 February 2019. Enrolled patients undergoing IVF treatment were randomized either to engage sexual intercourse using the barrier contraception (Group A, n = 116) or to abstain (Group B, n = 107) one night before FET. The primary outcome was clinical pregnancy rate. RESULTS Patients having intercourse had higher clinical pregnancy rate (51.72% vs. 37.07%, P = 0.045) and implantation rate (38.31% vs. 24.77%, P = 0.005) compared to those did not engage intercourse. However, there was no significant difference of the spontaneous abortion rate between two groups (11.67% 33 vs. 14.63%, P = 0.662). CONCLUSIONS Sexual intercourse before embryo transfer may improve the clinical pregnancy and implantation rates during FET cycles. However, it should be noted that patients choose only one time for sexual intercourse, that is, the night before embryo transfer.

Abstract
No studies have been conducted on the impact of different types of ovulatory dysfunction on the outcomes of frozen-thawed embryo transfers (FETs) in a letrozole-stimulated cycle in women with polycystic ovarian syndrome (PCOS). This study aimed to compare whether pregnancy outcomes of the letrozole-induced protocol in FET cycles differed between oligo-ovulatory and anovulatory women with PCOS. In a retrospective cohort study, women with PCOS who had undergone letrozole-induced FET at a university-affiliated fertility clinic from February 2014 to October 2020 were identified. The primary end point was live birth rate (LBR) per embryo transfer. Propensity score matching and multivariate logistic regression analyses were performed to control for the relevant confounders. A total of 652 women with PCOS undergoing letrozole-induced FET were included in the final analysis. Three hundred sixty-three of these women had oligo-ovulatory periods, while 289 had anovulatory periods. Propensity score matching analysis showed that LBR did not differ between groups (36.8% in oligo-ovulatory group vs 32.8% in anovulatory group, P = .431). Nevertheless, after controlling for potential confounding factors, LBR was significantly lower in anovulatory than oligo-ovulatory women (adjusted odds ratio 1.57, 95% confidence interval 1.08-2.29, P = .018). Furthermore, the pregnancy loss rate among the oligo-ovulatory group remained lower than those among the anovulatory group (adjusted odds ratio 0.23, 95% confidence interval 0.12-0.44, P < .001). Despite adjustment for confounding factors, those with oligo-ovulatory PCOS had a higher LBR and lower pregnancy loss rate compared with those with anovulatory PCOS. This may indicate that when oligo-ovulation is detected, PCOS patients should be intervened in time to conceive as soon as possible. Prospective studies must be conducted in the future to verify our findings.

Abstract
Study question In a modified natural cycle frozen-thawed embryo transfer (mNC-FET), does the premature timing of progesterone luteal phase support (LPS) initiation 24 h following human chorionic gonadotropin (hCG) trigger impact live birth? Summary answer Premature LPS initiation did not negatively affect the live birth rate (LBR) in mNC-FET cycles compared with conventional LPS initiation 48 h after hCG triggering. What is known already During natural cycle FET, human chorionic gonadotropin is routinely used to mimic endogenous luteinizing hormone (LH) surge to induce ovulation, which allows more flexibility in embryo transfer scheduling, thus relieving the burden of multiple visits by patients and laboratory workloads, which is also known as mNC-FET. Moreover, recent data demonstrates that ovulatory women undergoing natural cycle FETs have a lower risk of maternal and fetal complications due to the essential role of the corpus luteum in implantation, placentation and pregnancy maintenance. While several studies have confirmed the positive effects of LPS in mNC-FETs, the timing of progesterone LPS initiation is still unclear, as compared with fresh cycles where robust research has been conducted. To the best of our knowledge, no clinical studies comparing different beginning days in mNC-FET cycles have been published. Study design size duration This retrospective cohort study involved 756 mNC-FET cycles performed at a university-affiliated reproductive center between January 2019 and August 2021. The primary outcome measured was the LBR. Participants/materials setting methods Ovulatory women ≤42 years of age who were referred for their autologous mNC-FET cycles were included in the study. According to the timing of progesterone LPS initiation following the hCG trigger, patients were assigned into two categories: premature LPS group (progesterone initiation 24 h after hCG trigger, n = 182) versus conventional LPS group (progesterone initiation 48 h after hCG trigger, n = 574). Multivariate logistic regression analysis was used to control for confounding variables. Main results and the role of chance There were no differences in background characteristics between the two study groups, except for the proportion of assisted hatching (53.8% in premature LPS group versus 42.3% in conventional LPS group, p = 0.007). In the premature LPS group, 56 of 182 patients (30.8%) had a live birth, compared to 179 of 574 patients (31.2%) in the conventional LPS group, with no significant difference observed between groups (adjusted odds ratio [aOR] 0.98, 95% confidence interval [CI] 0.67-1.43, p = 0.913). In addition, there was no significant difference between the two groups in other secondary outcomes. A sensitivity analysis for LBR according to the serum LH and progesterone levels on hCG trigger day also confirmed the aforementioned findings. Limitations reasons for caution In this study, retrospective analysis was conducted in a single center and was therefore prone to bias. Additionally, we did not anticipate monitoring the patient's follicle rupture and ovulation after hCG triggering. Future prospective clinical trials remain necessary to confirm our results. Wider implications of the findings While exogenous progesterone LPS was added 24 h after hCG triggering, embryo-endometrium synchrony would not be adversely affected so long as sufficient time was allowed for endometrial exposure to exogenous progesterone. Our data support promising clinical outcomes following this event. As a result of our findings, clinicians and patients will be able to make better informed decisions. Study funding/competing interests No specific funding was available for this study. The authors have no personal conflicting interests to declare. Trial registration number N/A.

Abstract
INTRODUCTION The psychological well-being of pregnant women following assisted reproductive has increasingly gained attention in recent years. Anxiety and depression may be associated to pregnancy outcomes. This study aims to determine whether peer support and the WeChat group platform will reduce anxiety and depression among in vitro fertilization and embryo transfer (IVF-ET) women. METHODS AND ANALYSIS In the present randomized controlled study, 296 patients with confirmed clinical pregnancy following IVF-ET will be randomly assigned to receive standard intervention support or WeChat peer support on a 1:1 basis. The levels of anxiety and depression are the primary endpoints. Assessments will be performed at baseline measurements, first trimester, second trimester, and third trimester, and data will be collected. ETHICS AND DISSEMINATION This study has been approved as ethical by the affiliated hospital of Shandong University of Traditional Chinese Medicine's Reproductive Ethics Committee. Each patient will sign a written statement of informed permission. All information and biological samples will be legally protected. A peer-reviewed academic journal will publish the findings of this investigation. DISCUSSION Given the inconvenience of visits due to the current pandemic of COVID-19, this study addresses the patient's visit needs by combining WeChat, the most widely used social software in China, with peer support, while helping improve maternal anxiety, depression, and pregnancy outcomes following IVF-ET.

Abstract
IntroductionNowadays, frozen-thawed embryo transfer (FET) has become one of the standard treatments for infertility in the field of assisted reproductive technology (ART). Natural cycle FET (NC-FET) has many advantages, such as simplicity and economics, no effect on patients’ menstrual cycles, estrogen and progesterone levels, as well as no interference in endometrial growth and transformation, which is aligned with the natural physiological state of embryo implantation. Nonetheless, there is a controversy regarding the need for luteal phase support (LPS) during NC-FET cycles. The purpose of this study is to assess whether LPS was not inferior to non-LPS in terms of OPR in NC-FET cycles.Methods and analysisThis study including 1,010 ovulatory women undergoing in vitro fertilization (IVF)/intracytoplasmic sperm injection (ICSI) cycles with an elective freeze-all strategy followed by NC-FET will be performed at four university-affiliated reproductive centers. Participants will be randomly assigned in a 1:1 ratio to receive LPS treatment or not. This study is designed as an open-label, non-inferiority, randomized controlled trial (RCT), and the primary statistical strategies were intention-to-treat (ITT) and per-protocol (PP) analysis.DiscussionThere may not have been any significant difference in the chance of a live birth after FET if no progesterone was supplemental during the luteal phase. However, due to the limited number of previous studies, which are mainly retrospective, evidence is still limited. Thus, by conducting this multicenter RCT, we intend to evaluate whether LPS is necessary in NC-FET.Ethics and disseminationA Reproductive Ethics Committee of the Affiliated Hospital of Shandong University of Traditional Chinese Medicine (SDUTCM) has approved this study. This study will handle the data as required by general data protection regulations. Participants will sign a written informed consent regarding participation in the study and storage of blood samples in a biobank for future research. This study will be monitored by study personnel trained in Good Clinical Practice who are not involved in the study. The results of this study will be disseminated through publication in international peer-reviewed scientific journals.Clinical trial registration[https://www.chictr.org.cn/], identifier [ChiCTR2200057498].

Abstract
OBJECTIVE The purpose of this study is to determine whether intracytoplasmic sperm injection (ICSI) is beneficial in patients with non-male factor infertility. METHODS This systematic review and meta-analysis included articles from inception to May 2022. Published studies of non-male factor infertile women undergoing ICSI or in vitro fertilization (IVF) included in PubMed, Embase, web of science, Wanfang Database, and CNKI were searched by computer, without language restrictions. A random-effect model was applied to calculate the risk ratios (RRs) and their 95% confidence intervals (CIs). Letters, case reports, and review articles including meta-analyses and expert opinions were excluded. The primary endpoints were laboratory outcomes and pregnancy outcomes. The Secondary endpoints were neonatal outcomes. RESULTS Six randomized controlled studies and 20 retrospective cohort studies met the inclusion criteria. In meta-analytic forest plots, compared with IVF, those who received ICSI treatment were not different in fertilization rate (RR = 0.99, 95% CI [0.90-1.09], P = 0.88), total fertilization failure rate (RR = 1.30, 95% CI [1.17-1.45], P < 0.00001), and good quality embryo rate (RR = 0.94, 95% CI [ 0.86-1.02], P = 0.15), clinical pregnancy rate (RR = 0.84, 95% CI [0.70-1.01], P = 0.06), live birth rate (RR = 0.89, 95% CI [0.77-1.03], P = 0.13), miscarriage rate (RR = 1.06, 95% CI [0.78-1.43], P = 0.71), preterm neonatal delivery rate (RR = 0.92, 95% CI [0.67-1.26], P = 0.61), and low neonatal weight rate (RR = 1.13, 95% CI [0.80-1.61], P = 0.48). However, the implantation rate of IVF was better than ICSI (RR = 0.77, 95% CI [0.64-0.93], P = 0.005). In the subgroup analysis of the live birth rate of fresh embryo transfer, IVF performed in those ≥35 years had a higher live birth rate (RR = 0.82, 95% CI [0.78-0.83], P < 0.001). CONCLUSION The findings of this study indicate that ICSI is not superior to IVF in the treatment of infertility related to non-male factors. In order to confirm this result, more high-quality clinical studies are needed.

Abstract
BACKGROUND Endometriosis (EM) leads to a decline in fertility, which is characterized by a decrease in the number and quality of follicles, and thus has a negative impact on in vitro fertilization (IVF) outcomes. However, the mechanism of how EM affects oocytes and leads to infertility remains unclear. As a potentially available sample directly related to oocyte growth, follicular fluid (FF) has important research value. Evaluating the association of FF content and EM-associated infertility through proteomics may helpful to explore the possible pathogenesis of EM-associated infertility. METHODS In the present experimental study, from August 2019 to June 2020, FF samples were obtained as control group (CON-G; n = 10) from women with no one female factor of infertility and were undergoing IVF due to other reasons, 20 women with EM-associated infertility undergoing IVF with no other female factors were distributed into the EM group according to the time for IVF: (i) EM-group 1 (EM-G1, Stage I to Stage III, n = 10); (ii) EM-group 2 (EM-G2, Stage I to Stage III, n = 10). label-free quantitative proteomics (LFQP) technology and parallel reaction monitoring (PRM) approach were combined to aid in identifying and validating FF protein biomarkers for EM-associated infertility. In PRM analysis, another 20 subjects were enrolled as EM-associated infertility group (EM,Stage I to Stage III, n = 10) and controls (CON, n = 10) within the same time and inclusion criteria are the same as previously described. Finally, a potential protein biomarker panel of FF differential expressed proteins to EM-associated infertility was also evaluated by t-test and receiver operating characteristic (ROC) curve and binary Logistic regression models. RESULTS 7 significant differential expressed proteins which closely related to EM-associated infertility were found by LFQP technology, among which immunoglobulin lambda variable 7-46 (IGLV7-46), Immunoglobulin heavy constant gamma 2 (IGHG2), glia-derived nexin (GDN) and Inter-alpha-trypsin inhibitor heavy chain H3 (ITIH3) were significantly up-regulated (p < 0.05), while corticosteroid-binding globulin (CBG), angiotensinogen (AGT) and Fetuin-B (FETUB) were significantly down regulated (p < 0.05). Additionally, GDN and AGT was identified as a potential protein biomarker by further PRM analysis for EM-associated infertility according to ROC curve analysis and t-test (p < 0.05), the area under the curve (AUC) for GDN and AGT was 0.78 and 0.69 with optimum sensitivity of 50%, 70% and specificity of 100%, 90%, respectively. According to binary logistic regression and evaluated ROC analysis, the AUC for the combination of GDN and AGT was 0.80. CONCLUSIONS To the best of our knowledge, this is the first time that elevated GDN protein levels have been found in the FF of patients with EM-associated infertility. Combining LFQP technology and PRM method we found the abnormal of GDN and AGT in FF may be the potential cause of EM-associated infertility which may help to better understand the physiological and pathological mechanism of EM-associated infertility. Further experimental studies are required to confirm their mechanism in EM-associated infertility. The results of this study are also consistent with the previous conclusion that EM is a chronic inflammatory disease. SIGNIFICANCE To the best of our knowledge, this is the first time that elevated GDN protein levels have been found in the follicular fluid of patients with EM-associated infertility. Combining LFQP technology and PRM methods we found the abnormal of GDN and AGT protein in FF may be the potential cause of EM-associated infertility which may help to better understand the physiological and pathological mechanism of EM-associated infertility. Clinically, it has been recognized that EM is related to infertility, but the mechanism remains unclear. Our study combines label-free quantitative proteomics technology and parallel reaction monitoring methods to identify and verify the FF protein biomarkers of EM-associated infertility, which provides a good research method for follow-up research.

Abstract
OBJECTIVE To evalvate efficacy of Qizi Yusi Pills (QYP), a Chinese medicine compound preparation, on in vitro fertilization-embryo transfer (IVF-ET) in women of advanced reproductive age. METHODS This multicenter, randomized, double-blind, placebo-controlled trial was conducted from June 2018 to October 2019. A total of 124 patients were randomly allocated to either the QYP group or the placebo group using a stratified block randomization design, with 62 patients in each group. All patients completed controlled ovarian stimulation using a standard gonadotropin-releasing hormone agonist (GnRH-a) long protocol. As the QYP group, QYP was administered while the control group received placebo. QYP and placebo were administered for a total of 24 to 30 days from the day of GnRH-a pituitary downregulation to transvaginal oocyte retrieval. Both medications were taken orally at doses of 10 g three times each day. The primary outcome was cumulative pregnancy rate, and the secondary outcomes were periodic medication, follicular status, serum hormone and endometrial receptivity. Follow-up continued until 4 weeks after delivery. Maternal and neonatal complications, such as gestational diabetes, were also observed. RESULTS Overall, 119 patients completed the study, 60 in the QYP group and 59 in the placebo group. Per protocol (PP) analysis revealed that 6-month cumulative pregnancy rate in the QYP group was significantly higher than that in the placebo group [43.33% (26/60) vs. 25.42% (15/59), P=0.040). Additionally, more oocytes were retrieved from the QYP group than those from the placebo group (8.95 ± 3.12 vs. 7.85 ± 1.91, P=0.022). Moreover, the endometrial thickness of HCG day in the QYP group was significantly higher than that in the placebo group (11.78 ± 2.27 mm vs. 10.68 ± 2.07 mm, P=0.012). Maternal and neonatal complications between the two groups were not significantly different (P>0.05). Intention-to-treat analysis was in line with PP results. CONCLUSIONS QYP can enhance ovarian reserve capacity and ovarian response, and possibly promote endometrial receptivity. QYP effectively improves cumulative pregnancy rates in older patients (⩾35 years) undergoing IVF-ET. (Registration No. ChiCTR1800014427).

Abstract
Research question What influence does seven days of oestrogen administration versus fourteen days have on the reproductive outcomes of frozen-thawed embryo transfer (FET) in programmed endometrial preparation cycles? Design In a retrospective study, conducted at a university-affiliated tertiary hospital, a total of 2628 infertile patients (4142 FET cycles) were divided into one of two groups between January 2014 and December 2020: group A (n = 1406, seven days of oestrogen before progesterone (P4) supplementation) and group B (n = 2716, fourteen days of oestrogen before P4 supplementation). The primary outcome was cumulative live birth rate (CLBR). Secondary outcomes were other pregnancy-related outcomes, maternal and neonatal complications. Results No significant difference in CLBR was observed when comparing seven versus fourteen days of oestrogen administration before starting P4 supplementation (47.6% vs. 48.8%, P = 0.537). Furthermore, multivariable logistic regression analysis revealed that oestrogen administration in programmed FET cycles (7 days vs. 14 days) was not significantly associated with CLBR (OR 1.04, 95% CI 0.89–1.23). The risks of maternal and neonatal complications were comparable between the two groups. Conclusions Variation in the duration of oestradiol supplementation before P4 initiation does not impact FET reproductive outcomes. For infertile women who desire to conceive as soon as feasible, short (seven days) oestrogen administration in a programmed FET cycle may be a suitable alternative.

Abstract
INTRODUCTION The choice of trigger drug for the controlled ovarian hyperstimulation (COH) protocol correlates with the outcome of in vitro fertilization/intracytoplasmic sperm injection embryo transfer (IVF/ICSI-ET). The co-administration of gonadotropin releasing hormone agonist (GnRH-a) and human chorionic gonadotropin (hCG), i.e., dual trigger, for final oocyte maturation, has received much attention in recent years. This trial was designed to determine whether a dual trigger approach by lengthening the time between trigger and ovum pick-up (OPU) improves the quantity and quality of mature oocytes/top-quality embryos and pregnancy outcomes in expected normal responders with a high immature oocyte rate. METHODS AND ANALYSIS We propose a study at the Affiliated Hospital of Shandong University of Chinese Medicine. A total of 90 individuals undergoing COH use a fixed GnRH antagonist protocol. They will be assigned randomly into two groups according to the trigger method and timing: recombinant hCG (6500 IU) will be injected only 36 hours before OPU for final oocyte maturation (hCG-only trigger); co-administration of GnRH-a and hCG for final oocyte maturation, 40 and 34 hours prior to OPU, respectively (Dual trigger). The primary outcome is metaphase-II (MII) oocytes rate. Secondary outcomes are number of oocytes retrieved, fertilization rate, top-quality embryos rate, blastula formation rate, embryo implantation rate, clinical pregnancy rate, miscarriage rate, live birth rate, cumulative pregnancy/live birth rates, and ovarian hyperstimulation syndrome (OHSS) rate. ETHICS AND DISSEMINATION The reproductive ethics committee of the Affiliated Hospital of Shandong University of Traditional Chinese Medicine certified this study (Identifier: SDUTCM/2021.7.26) as ethical. All individuals will sign written informed consent. All data and biological samples will be protected according to law. The results of this study will be disseminated in a peer-reviewed scientific journal. CLINICAL TRIAL REGISTRATION [chictr.gov.cn], identifier [ChiCTR2100049292].

Abstract
Objective: To evaluate the diagnostic performance of the Chinese Ultrasound Thyroid Imaging Reporting and Data System (C-TIRADS) in thyroid nodules,and to compare it with the TIRADS proposed by Kwak et al. (K-TIRADS) and the TIRADS proposed by the American College of Radiology (ACR-TIRADS). Methods: The data of 1 750 patients with 2 029 thyroid nodules in the Department of Thyroid Surgery, the Affiliated Hospital of Jining Medical University from January 2018 to November 2020 was retrospectively collected. Among them, there were 328 males and 1 422 females,aged from 6 to 86 with an average of (47±12) years. The nodules were divided into≤1.0 cm group(n=997) and>1.0 cm group(n=1 032)based on the size of the nodules. The stratification for malignant risk and the determination of benign or malignancy of the nodules was evaluated using the C-TIRADS, K-TIRADS and ACR-TIRADS, respectively. The receiver operating characteristic (ROC)curve analysis was performed to compare the diagnostic performance of the aforementioned three kinds of TIRADS using pathological results as the referent standard. Results: The optimal diagnosis points in the determination of malignant nodules of C-TIRADS, K-TIRADS and ACR-TIRADS in the two groups were 4A, 4b and 4 respectively according to ROC curve analysis. For the diagnosis of the malignant nodules, the C-TIRADS achieved with an AUC value of 0.772 and 0.892 in the ≤1.0 cm group and>1.0 cm group, respectively, which was significantly higher than K-TIRADS (AUC= 0.762 and 0.869, respectively) and ACR-TIRADS (AUC= 0.735 and 0.832, respectively) (P<0.05). The sensitivity, specificity, accuracy, positive predictive value and negative predictive value of C-TIRADS were 94.99%, 59.41%, 86.46%, 88.13%, 78.89% (≤1.0 cm group)and 88.34%, 90.05%, 89.34%, 86.33%, 91.57%(>1.0 cm group), respectively. C-TIRADS had the highest sensitivity, accuracy, and negative predictive value in the determination of malignant nodules in both groups compared to the other two kinds of TIRADS. Conclusions: The three kinds of TIRADS all have high diagnostic performance for the determination of the malignant nodules, and the C-TIRADS has the best overall efficacy, which can effectively assist clinicians for medical decision, and is worth to be popularized and applied in the clinical setting.

Abstract
Objective: The aim of this study is to investigate, in ovulatory patients, whether there is a difference in reproductive outcomes following frozen-thawed embryo transfer (FET) in natural cycles (NC) compared to modified natural cycles (mNC). Methods: This retrospective cohort study, performed at the public tertiary fertility clinic, involved all infertile patients undergoing endometrial preparation prior to FET in NC and mNC from January, 2017 to November, 2020. One thousand hundred and sixty-two patients were divided into two groups: mNC group (n = 248) had FET in a NC after ovulation triggering with human chorionic gonadotropin (hCG); NC group (n = 914) had FET in a NC after spontaneous ovulation were observed. The primary outcome was live birth rate. All pregnancy outcomes were analyzed by propensity score matching (PSM) and multivariable logistic regression analyses. Results: The NC group showed a higher live birth rate [344/914 (37.6%) vs. 68/248 (27.4%), P = 0.003; 87/240 (36.3%) vs. 66/240 (27.5%), P = 0.040] than the mNC group before and after PSM analysis. Multivariable analysis also showed mNC to be associated with a decreased likelihood of live birth compared with NC [odds ratio (OR) 95% confidence interval (CI) 0.71 (0.51–0.98), P = 0.039]. Conclusion: For women with regular menstrual cycles, NC-FET may have a higher chance of live birth than that in the mNC-FET cycles. As a consequence, it's critical to avoid hCG triggering as much as possible when FETs utilize a natural cycle strategy for endometrial preparation. Nevertheless, further more well-designed randomized clinical trials are still needed to determine this finding.

Abstract
BACKGROUND The optimal time at which to perform a frozen-thawed embryo transfer (FET) following a failed in-vitro fertilization-embryo transfer (IVF-ET) attempt remains elusive to most reproductive experts. Physicians often delay the introduction of FET due to concerns related to potential residual effects of ovarian hyperstimulation which may interfere with the regular menstrual cycle. Moreover, given that most of the published studies on the topic are retrospective and have inconsistent findings, it is crucial to develop evidence-based randomized control guides for clinical practice. Therefore, this well-designed randomized controlled trial (RCT) was conducted to determine whether it is necessary to delay FET for at least one menstrual cycle after the failure of fresh embryo transfer. METHODS Infertile women eligible for IVF-ET were invited to participate in this multicenter, randomized, non-inferiority, parallel-group, unblinded, controlled trial at the academic fertility centers of four public hospitals in Chinese Mainland. Infertile women scheduled to receive their first FET cycle after a failed IVF-ET attempt were randomly assigned to either (a) the immediate FET group in which FET was performed in the first menstrual cycle following the failed IVF-ET cycle (n = 366) or (b) the delayed FET group in which FET was performed in the second or subsequent menstrual cycle following the failed IVF-ET cycle (n = 366). All FET cycles were performed during hormone replacement cycles for endometrial preparation. The primary outcome was the ongoing pregnancy, defined as a detectable fetal heart beat beyond twelve weeks of gestation. Secondary outcomes were other pregnancy-related outcomes, maternal and neonatal complications. Analysis was performed by both intention-to-treat and per-protocol principles. RESULTS A total of 646 FETs were completed. The frequency of moderate to severe depression and high stress level prior to FET in delayed FET group were significantly higher than that in immediate FET group (10.6% vs 6.1%, p = 0.039; 30.3% vs 22.4%, p = 0.022, respectively). Immediate FET resulted in a higher frequency of clinical pregnancy than did delayed FET (41.7% vs 34.1%), for a relative risk (RR) of 1.23 (95% confidence interval [CI], 1.00-1.50; p = 0.045). Women who underwent immediate FET also had a lower frequency of biochemical pregnancy loss (11.7% vs. 30.6%), with a RR of 0.28 (95% CI 0.23-0.63, p < 0.001), and a higher frequency of embryo implantation (25.2% vs. 20.2%), with a RR of 1.25 (95% CI 1.01-1.53; p = 0.038). Although the ongoing pregnancy and live birth rates did not differ significantly between the immediate FET and delayed FET groups (37.1% vs 30.3%, RR 1.22, 95% CI 0.99-1.52, p = 0.067; 36.5% vs 30.0%, RR 1.22, 95% CI 0.98-1.52, p = 0.079, respectively), a multivariate logistic regression analysis adjusted for potential confounders such as depression and stress levels revealed that the immediate FET group had a significantly higher ongoing pregnancy and live birth rates than the delayed FET group (odds ratio 0.68, 95% CI 0.47-0.99, p = 0.041; odds ratio 0.67, 95% CI 0.46-0.96, p = 0.031). The risks of maternal and neonatal complications were comparable between the two groups. CONCLUSIONS In women with a previous failed IVF-ET attempt, immediate FET resulted in higher ongoing pregnancy and live birth rates than delayed FET. These findings warrant caution in the indiscriminate application of a delayed FET strategy when apparent risk of high stress level is perceived. TRIAL REGISTRATION ChiCTR2000033313 .

Abstract
Objective The principal purpose of this study was to compare reproductive outcomes for stimulated cycles (STC) and hormone replacement cycles (HRC) for endometrial preparation before frozen-thawed embryo transfer (FET) in young women with polycystic ovary syndrome (PCOS). Methods We conducted a retrospective study of 1434 FET cycles from January, 2017 to March, 2020 in our reproductive center, in which stimulated and hormone replacement cycles were used for endometrial preparation. Pregnancy outcomes of couples undergoing routine STC-FET or HRC-FET were analyzed by propensity score matching (PSM) and multivariable logistic regression analyses. Results Data on 1234 HRC protocols (86% of the total) and 200 STC protocols (14%) were collected. After PSM, 199 patients were included in both groups, respectively. There was no significant difference in positive pregnancy rate (52.7% vs 54.8%, p=0.763), clinical pregnancy rate (51.8% vs 52.8%, p=0.841), live birth rate (45.2% vs 43.7%, p=0.762), pregnancy loss rate (9.7% vs 16.2%, p=0.164) and ectopic pregnancy rate (1.5% vs 0.5%, p=0.615) between STC and HRC protocols. Subsequent multivariate logistic regression analysis also yielded similar results. Conclusion STC for endometrial preparation had similar pregnancy outcomes compared with HRC protocols. Evidence is available which shows that for young women with PCOS in preparation for FET, HRC could be a reasonable choice for patients who are unwilling to accept injections. However, STC may reduce unnecessary anxiety and operational costs and offer more flexibility for patients. Eventually, we must embrace the concepts of individualization, securitization, and optimization in the clinic.

Abstract
Apparent diffusion coefficient(ADC) of magnetic resonance imaging≤0.90×10-3 mm2/s and T2-hypointensity, intratuminal septa, and peritumoral infiltration could achieve best diagnostic efficiency. ADC values and cyst or necrosis were independent predictors for the differential diagnosis of nonseminomatous germ cell tumor versus seminoma and nonseminomatous germ cell tumor versus lymphoma. ADC value and intratuminal septa were independent predictors for the differential of seminoma versus lymphoma.

Abstract
OBJECTIVE The primary objective of the study was to assess traditional Chinese formula DKP supplementation in terms of efficacy and safety on reproductive outcomes of expected poor ovarian responder (POR, POSEIDON Group 4) undergoing in vitro fertilization-embryo transfer (IVF-ET). DESIGN SETTING AND PARTICIPANTS Women eligible for IVF-ET were invited to participate in this randomized, double-blind, placebo-controlled, superiority trial at academic fertility centers of ten public hospitals in Chinese Mainland. A total of 462 patients (35-44 years) equally divided between DKP and placebo groups with antral follicle count (AFC) <5 or anti-müllerian hormone (AMH) <1.2 ng/ml were randomized. INTERVENTIONS All participants were given DKP or 7 g placebo twice daily on the previous menstrual cycle day 5 until oocyte retrieval, which took approximately 5 to 6 weeks. MAIN OUTCOME MEASURE The primary outcome was the ongoing pregnancy defined as more than 20 gestational weeks of an intrauterine living fetus confirmed by pelvic ultrasonography. RESULTS Demographic characteristics were equally distributed between the study populations. Intention-to-treat (ITT) analysis revealed that ongoing pregnancy rate (OPR) was not significantly different between DKP and placebo groups [26.4% (61/231) versus 24.2% (56/231); relative risk (RR) 1.09, 95% confidence interval (CI) 0.80 to 1.49, P = 0.593]. No significant differences between groups were observed for the secondary outcomes. The additional per protocol (PP) analysis was in line with ITT results: OPR in DKP group was 27.2% (61/224) versus 24.1% (55/228) in placebo group [RR 1.13, 95%CI (0.82 to 1.55), P = 0.449]. After subgroup analysis the findings concluded that POR population of 35-37 years had a significantly higher OPR after 5-6 weeks of oral DKP (41.8%, 33/79) versus placebo (25.4%, 18/71) [RR 1.65, 95% CI (1.02 to 2.65), P = 0.034, P for interaction = 0.028]. CONCLUSION This well-designed randomized controlled trial (RCT) offers new high-quality evidence to supplement existing retrospective literature concerning DKP performance in expected PORs. DKP could be recommended as a safe and natural remedy for expected PORs (aged 35-37 years) who fulfill the POSEIDON group 4 criteria. However, additional interventional clinical studies are undoubtedly required to be conducted in the future to validate this hypothesis.

Abstract
OBJECTIVE To explore how waiting time after failed fresh cycle embryo transfer affects the pregnancy outcomes of the next frozen embryo transfer (FET). METHODS A retrospective analysis was carried out on the data of women who had received at least one FET after a failed fresh embryo transfer between January 2013 to December 2019. The women were grouped based on the "time" of the first FET, referring to the period between a failed fresh embryo transfer and the beginning of the next cycle of FET. This time is divided into two classes: immediate (<90 days after the failed fresh embryo transfer) and delayed (≥90 days after failed fresh embryo transfer). The following parameters were investigated: clinical pregnancy rate; biochemical pregnancy rate; ectopic pregnancy rate; and non-pregnancy rate. RESULTS A total of 293 cases of fresh embryo transfer cycles were included. No significant differences in the number of obtained oocytes, total number of FET, and the total amount of gonadotropin were seen between the immediate and delayed fresh embryo transfer groups. The pregnancy outcomes of the two groups were similar. CONCLUSION The duration of waiting time between failed fresh embryo transfer and the next FET does not affect pregnancy outcomes.

Abstract
The single nucleotide polymorphism T-1031C has shown to have an important role in the regulation and transcription efficiency of TNF-α gene. Yet, the relationship between TNF-α T-1031C gene polymorphism and the development of endometriosis (EM) still remains unclear. The aim of this meta-analysis was to summarize the effects of TNF-α T-1031C gene polymorphism and clarify their possible association with EM. A comprehensive literature search was performed using PubMed, EMBASE, Web of Science, and the Cochrane Central Register of Controlled Trials (up to August 10, 2019). A fixed- or random-effects model was employed according to the heterogeneity among studies. The log odds ratios and 95% confidence intervals (CIs) were estimated in the models of allele comparison (T vs C), homozygote comparison (TT vs CC) and (TC vs CC), dominant (TT vs TC + CC), hyperdominant (TT + CC vs TC), and recessive (TT + TC vs CC) to estimate the strength of the associations. A total of 7 case-control studies were included in this meta-analysis. Overall, significant associations between TNF-α T-1031C and EM were identified from (T vs C: log OR [95% CI] = 0.31 [-0.09, 0.71]; TT + CC vs TC: 0.27 [0.04, 0.50]; TC + CC vs TT: -0.83 [-1.19, -0.47]). On the other hand, no significant correlation was found in other gene models (TT vs TC: log OR [95% CI] = 0.89 [0.64, 1.13]; TT vs CC: 0.3 [-0.74, 1.36]; TT + TC vs CC: 0.17 [-0.81, 1.15]). In subgroup analyses by ethnicity or HWE P-value, there was a statistically significant association between TNF-α T-1031C polymorphisms and EM in the dominant model (TT vs TC + CC: log OR [95%] = -0.84 [-1.60, -0.09]) for the European population, and in hyperdominant model (TT + CC vs TC: log OR [95%] = 0.24 [0.001, 0.49]) for Asian population. To sum up, this meta-analysis showed that TNF-α T-1031C polymorphism was associated with EM susceptibility and has a protective effect in Asian and European populations.

Abstract
BACKGROUND Neurotrophins [nerve growth factor (NGF), brain-derived neurotrophic factor (BDNF), neurotrophin-3 (NT-3), and neurotrophin-4 (NT-4)] and glial cell line-derived neurotrophic factor (GDNF) are soluble polypeptide growth factors that are widely recognized for their roles in promoting cell growth, survival and differentiation in several classes of neurons. Outside the nervous system, neurotrophin (NT) and GDNF signaling events have substantial roles in various non-neural tissues, including the ovary. OBJECTIVE AND RATIONALE The molecular mechanisms that promote and regulate follicular development and oocyte maturation have been extensively investigated. However, most information has been obtained from animal models. Even though the fundamental process is highly similar across species, the paracrine regulation of ovarian function in humans remains poorly characterized. Therefore, this review aims to summarize the expression and functional roles of NTs and GDNF in human ovarian biology and disorders, and to describe and propose the development of novel strategies for diagnosing, treating and preventing related abnormalities. SEARCH METHODS Relevant literature in the English language from 1990 to 2018 describing the role of NTs and GDNF in mammalian ovarian biology and phenotypes was comprehensively selected using PubMed, MEDLINE and Google Scholar. OUTCOMES Studies have shown that the neurotrophins NGF, BDNF, NT-3 and NT-4 as well as GDNF and their functional receptors are expressed in the human ovary. Recently, gathered experimental data suggest putative roles for NT and GDNF signaling in the direct control of ovarian function, including follicle assembly, activation of the primordial follicles, follicular growth and development, oocyte maturation, steroidogenesis, ovulation and corpus luteum formation. Additionally, crosstalk occurs between these ovarian regulators and the endocrine signaling system. Dysregulation of the NT system may negatively affect ovarian function, leading to reproductive pathology (decreased ovarian reserve, polycystic ovary syndrome and endometriosis), female infertility and even epithelial ovarian cancers. WIDER IMPLICATIONS A comprehensive understanding of the expression, actions and underlying molecular mechanisms of the NT/GDNF system in the human ovary is essential for novel approaches to therapeutic and diagnostic interventions in ovarian diseases and to develop more safe, effective methods of inducing ovulation in ART in the treatment of female infertility.

Abstract
Objective: To investigate the effect of the duration of gonadotropin releasing hormone agonist (GnRH-a) use on the outcome of in vitro fertilization and embryo transfer (IVF-ET) during the short-acting long-term hyperstimulation cycle. Methodology: Clinical data from 776 patients receiving controlled ovarian stimulation (COS) after short-term regimen downregulation were retrospectively analyzed. According to the duration of GnRH-a, the patients were divided into 3 groups: Group A, 14 days for GnRH-a; Group B, 15-17 days for GnRH-a; and Group C, >18 days for GnRH-a. The clinical data, treatment and clinical outcomes were compared among the groups. Results: There were no significant differences in fertilization rate, implantation rate, clinical pregnancy rate, abortion rate, ovarian hyperstimulation syndrome (OHSS) rate(P > 0.05). The total costs in group A were significantly less than those in group B and C(P < 0.001). The number of eggs and quality embryos generated in group A was significantly higher than that in groups B and C (P = 0.014, P = 0.005). Conclusions: In the short-acting GnRH agonist long protocol, satisfactory IVF-ET pregnancy outcome was obtained with the use of GnRH-a for 14 days under the premise of lowering the receptor-regulating standard. Excessive application of GnRH-a will affect the number of eggs and embryos and increase the cost of medical treatment.

Abstract
BACKGROUND Borderline form of empty follicle syndrome is a condition in which only a few mature or immature oocytes are recovered after meticulous follicular aspiration, despite adequate ovarian response to stimulation. It is a rare phenomenon with an unclear cause. Currently, the condition still lacks effective treatment.
CASE SUMMARY A patient with secondary infertility who had undergone three cycles of assisted reproductive technique (ART) is described. With regard to good follicular response, two oocytes were obtained in the first two ART cycles, but no embryo was formed. In the third ART cycle, which is the subject of this study, ovulation was induced by dual trigger of a supernormal dose of human chorionic gonadotropin (HCG) combined with a delayed oocyte retrieval approach. The method involved administration of gonadotropin-releasing hormone agonist, recombinant HCG, and urinary HCG 39 h before ovum pick-up. Ten oocytes were recovered, two out of three mature eggs were fertilized after intracytoplasmic sperm injection, resulting in two embryos that were subsequently cryopreserved. The case report guidelines have been used herein to present the first case of this novel dual trigger method.
CONCLUSION This approach provides a new treatment option for patients with a similar condition in the future. This study can also inspire further investigation on the effects of various β-HCG serum levels 36 h after intramuscular HCG administration.

Abstract
Connexin 43 (Cx43)-coupled gap junctions in granulosa cells play an important role in follicular development, oocyte maturation, and corpus luteum maintenance. Bone morphogenetic protein 6 (BMP6) is highly expressed in human oocytes and granulosa cells and is involved in the regulation of female reproduction. Currently, whether oocyte- and granulosa cell-derived BMP6 affects the expression of Cx43 and its related gap junction intercellular communication (GJIC) activity in human granulosa cells remains unknown. In this study, we demonstrate that BMP6 treatment significantly suppressed the expression of Cx43 in both primary and immortalized (SVOG) human granulosa-lutein cells. Using both pharmacological inhibitors and small interfering RNA-mediated knockdown approaches, we demonstrate that ALK2 and ALK3 BMP type I receptors are involved in BMP6-induced suppressive effects on Cx43 expression and GJIC activity in SVOG cells. Furthermore, these cellular activities are most likely mediated by the SMAD1/SMAD5-SMAD4-dependent signaling pathway. Notably, the ChIP analyses demonstrated that phosphorylated SMADs could bind to human Cx43 promoter. Our findings provide new insight into the molecular mechanisms by which an intrafollicular growth factor regulates cell-cell communication in human granulosa cells.

Abstract
Objectives The aim of this study was to provide a comprehensive understanding of alterations in messenger RNAs (mRNAs), long noncoding RNAs (lncRNAs), and circular RNAs (circRNAs) in cartilage affected by osteoarthritis (OA). Methods The expression profiles of mRNAs, lncRNAs, and circRNAs in OA cartilage were assessed using whole-transcriptome sequencing. Bioinformatics analyses included prediction and reannotation of novel lncRNAs and circRNAs, their classification, and their placement into subgroups. Gene ontology and pathway analysis were performed to identify differentially expressed genes (DEGs), differentially expressed lncRNAs (DELs), and differentially expressed circRNAs (DECs). We focused on the overlap of DEGs and targets of DELs previously identified in seven high-throughput studies. The top ten DELs were verified by quantitative reverse transcriptase polymerase chain reaction (qRT-PCR) in articular chondrocytes, both in vitro and in vivo. Results In total, 739 mRNAs, 1152 lncRNAs, and 42 circRNAs were found to be differentially expressed in OA cartilage tissue. Among these, we identified 18 overlapping DEGs and targets of DELs, and the top ten DELs were screened by expression profile analysis as candidate OA-related genes. WISP2, ATF3, and CHI3L1 were significantly increased in both normal versus OA tissues and normal versus interleukin (IL)-1β-induced OA-like cell models, while ADAM12, PRELP, and ASPN were shown to be significantly decreased. Among the identified DELs, we observed higher expression of ENST00000453554 and MSTRG.99593.3, and lower expression of MSTRG.44186.2 and NONHSAT186094.1 in normal versus OA cells and tissues. Conclusion This study revealed expression patterns of coding and noncoding RNAs in OA cartilage, which added sets of genes and noncoding RNAs to the list of candidate diagnostic biomarkers and therapeutic agents for OA patients.

Abstract
OBJECTIVE To assess the difference in the metabolomics profiles of follicular fluid between older and younger reproductive-aged women. METHODS The retrospective study was conducted at the Centre of Reproduction and Genetics, Affiliated Hospital of Shandong University of Traditional Chinese Medicine, Jinan, China and comprised patient data related to the period between July and October 2015. Follicular fluid was obtained from male-factor infertility women aged 28-35 years as the younger group A, and those aged 35-42 years as the older group B. The subjects were undergoing in vitro fertilization / intracytoplasmic sperm injection and were retrospectively analysed by ultra-performance liquid chromatography-high-resolution mass spectrometry. The fragments were structurally identified using debris' information obtained from fragmented ion scans to identify the different compounds. RESULTS Of the 55 cases studied, 28(51%) were in group A with a mean age of 29.57 ± 2.92 years, and 27(49%) were in group B with a mean age of 39.19±2.95 years. Compared with the group A, four types of compounds, hormones, licithin, lysophospholipids, and protein degradation fragments, were expressed significantly differentially in group B (p<0.05 each). Nicotine glucuronide and phosphatidylcholine were found only in Group B follicular fluid. CONCLUSIONS The components of follicular fluid and relative contents were found changed with ageing.

Abstract
Objective: To study the relationship between the weight change trend of initial treatment patients with pulmonary tuberculosis and the dose change trend of isoniazid, and therefore to analyze the appropriate dose of isoniazid. Methods: Data of initial treatment inpatients with pulmonary tuberculosis from May 1955 to December 2012 were retrospectively analyzed. Elderly patients with pulmonary tuberculosis, patients with drug-resistant tuberculosis, extrapulmonary tuberculosis and those with complications were excluded from the study. The time period was separated as 20th century 1950s to 1960s, 1970s, 1980s, 1990s, 21th century 2000s and 2010s. Samples were selected in each year and month between 1950s to 1960s and 1970s. After 1980s, samples of 1 year were taken from each 5 years. The sex, age and weight for every patient were collected, as well as the dose of isoniazid of every inpatient on a day in therapeutic regimen. Meanwhile, the weight change trend of the patients in different ages and the dose change trend of isoniazid were compared. The total number of cases was 1 398, with 924 males and 474 females, averaging (36.7±14.4) years old. Results: The weight of the patients increased when it was compared between that in 1950s to 1960s, 1970s or 1980s and that in 2000s, with a increasing weight of 3 kg, 3.5 kg and 3 kg respectively. The difference showed statistical significance (P<0.003). The difference was also significant when the weight in 70s was compared with that in 2010s (P=0.002). The therapeutic dose of isoniazid remained invariable regardless of the weight change. At 1990s, 2000s and 2010s, the dose of isoniazid per kilogram of body weight would reduce to 0.005 4 g, 0.005 2 g and 0.0054 g relative to patients' weight increase, and the difference was statistically significant (P<0.001). Conclusions: The weight of pulmonary tuberculosis inpatients increased in recent 60 years. The weight has a close relation with the dose of isoniazid. A fixed dose of isoniazid (0.3 g/d) regardless of the weight change could result in low blood drug concentration . To avoid tolerance of isoniazid and increase the cure rates of pulmonary tuberculosis, the dosage of isoniazid should be increased based on the weight increase of patients.

Abstract
Objective: To investigate the effect of nicorandil on ventricular arrhythmia in patients with acute ST-segment elevation myocardial infarction (STEMI) treated with emergent percutaneous coronary intervention (PCI). Methods: A total of 120 acute STEMI patients treated with emergent PCI in our hospital from January 2015 to June 2016 were randomly divided into control group and experiment group (n=60 each). Patients in both groups received conventional therapy.Patients in experiment group took 10 mg nicorandil orally before PCI and received oral nicorandil treatment (15 mg/d, three times daily) for 3 days.QT disperse(QTd), correct QTd(QTcd) and the occurrence rate of ventricular arrhythmia were compared between two groups. Results: QTd at 6, 24, 48 and 72 hours((70.6±4.4), (67.2±5.3), (55.7±8.5), (48.2±8.2) ms, respectively) after PCI was significantly lower in the experiment group than those of control group ((77.1±7.1), (71.3±6.5), (65.1±8.1), (57.2±5.4) ms, all P<0.05). The level of QTd was also significantly lower in the experiment group at 6, 24, 48 and 72 hours((77.5±7.7), (67.7±8.6), (61.2±7.5), (52.9±8.4) ms, respectively) after PCI comared to those of control group ((88.6±8.1), (79.2±7.8), (74.4±7.4), (69.6±8.6) ms, all P<0.05). There was no significant difference in the incidence of reperfusion arrhythmia during PCI procedure between the two groups.The prevalence of the ventricular premature beat in the experiment group (25/60, 41.7%) was significantly lower than in the control group(45/60, 75.0%) within 3 days after PCI(P<0.01), the prevalence of the no sustained ventricular tachycardia and ventricular fibrillation in the experiment group(6/60, 10.0%) was also significantly lower than in the control group (18/60, 30.0%, P<0.01) within 3 days after PCI. Conclusions: Nicorandil use prior and post PCI could decrease the occurrence rate of ventricular arrhythmia in STEMI patients undergoing emergent PCI, and this effect might be related with reduced QTd and QTcd post medication.

Abstract
Objective: Using the standard genotype method, variable number of tandem repeats (VNTR), we constructed a VNTR database to cover all provinces and proposed a set of optimized VNTR loci combinations for each province, in order to improve the preventive and control programs on tuberculosis, in China. Methods: A total of 15 loci VNTR was used to analyze 4 116 Mycobacterium tuberculosis strains, isolated from national survey of Drug Resistant Tuberculosis, in 2007. Hunter-Gaston Index (HGI) was also used to analyze the discriminatory power of each VNTR site. A set combination of 12-VNTR, 10-VNTR, 8-VNTR and 5-VNTR was respectively constructed for each province, based on 1) epidemic characteristics of M. tuberculosis lineages in China, with high discriminatory power and genetic stability. Results: Through the completed 15 loci VNTR patterns of 3 966 strains under 96.36% (3 966/4 116) coverage, we found seven high HGI loci (including QUB11b and MIRU26) as well as low stable loci (including QUB26, MIRU16, Mtub21 and QUB11b) in several areas. In all the 31 provinces, we found an optimization VNTR combination as 10-VNTR loci in Inner Mongolia, Chongqing and Heilongjiang, but with 8-VNTR combination shared in other provinces. Conclusions: It is necessary to not only use the VNTR database for tracing the source of infection and cluster of M. tuberculosis in the nation but also using the set of optimized VNTR combinations in monitoring those local epidemics and M. tuberculosis (genetics in local) population.

Abstract
OBJECTIVE To observe the effect of Yougui Formula Granule (YFG) on ovarian granulosa cells gene expression profiles in in vitro fertilization-embryo transfer (IVF-ET) patients of Shen yang deficiency syndrome (SYDS) from the viewpoint of genomics. METHODS Totally 72 infertility patients undergoing IVF-ET were randomly assigned to the treatment group and the control group according to random digit table, 36 in each group. Patients in the treatment group took YFG combined gonadotropin (Gn), while those in the control group took placebos combined Gn. All medication lasted for 3 menstrual cycles before IVF. With high-throughput gene sequencing technology, gene expression profiles of ovarian granulosa cells in the two groups were analyzed to explore the difference by gene ontology (GO) enrichment analysis and kyoto encyclopedia of genes and genomes (KEGG) pathway analysis. RESULTS Ovarian granulosa cell gene expression profiles from the follicular fluid showed, when compared with the control group, 391 differential genes were found in the syndrome-control group, 153 down-regulated and 238 upregulated. Enrichment of differentially expressed cellular location and molecular function of genes involved cell proliferation and apoptosis associated cyclin, protein ubiquitination, construction of microtubules and microfilament, mitochondrial function and energy-related factors, regulatory factors for hormone synthesis. Participated pathways involved energy metabolism pathway and transforming growth factor-β (TGF-β) signaling pathway. CONCLUSIONS There existed significant difference in gene expression profiles of ovarian granulosa cells between the treatment group and the control group. Differentially expressed genes involved in biological processes correlates with Shen yang deficiency induced proliferation of germ cells, confused apoptosis, and hindered process during which mitochondria produced energy.

Abstract
We report a memristive switching effect in Pt/CuOx/Si/Pt devices prepared by the rf sputtering technique at room temperature. Differently from other Cu-based metal filament switching systems, a gradual electroforming process, marked by a gradual increase of the device resistance and a gradual decrease of the device capacitance, was observed in the current-voltage and capacitance characteristics. After the gradual electroforming, the devices show a uniform memristive switching behavior. By Auger electron spectroscopy analysis, a model based on the thickness change of the SiOx layer at the CuOx/Si interface and Cu ion migration is proposed for the gradual electroforming and uniform memristive switching, respectively. This work should be meaningful for the preparation of forming-free and homogeneous memristive devices.

Abstract
OBJECTIVE To investigate the effects of Er'zhi Tiangui Granule (, ETG) on sequential expressions of integrinβ3 and its ligand osteopontin in the mouse endometrium during controlled ovarian hyperstimulation (COH) and implantation period. METHODS Seventy-five Mature female Kunming mice were randomly divided into 3 groups, a normal control group, a model group, and a treatment group administrated with ETG for 10 days, 25 in each group. After mated with male mice, every 5 mice were sacrified in each group at the 0, 2nd, 4th, 6th, and 8th days to take their endometrium. In-situ hybridization was used to detect the expressions of integrinβ3 and osteopontin in the endometrium. RESULTS mRNA expressions of integrinβ3 and osteopontin in the endometrium during implantation period showed similar time sequence rules in the treatment group to those in the normal control group; the peak values of them were a little lower in the treatment group than the normal control without significant differences. In the model group, integrinβ3 mRNA expression was higher at the 2nd day, obviously lower at the 4th and 6th days, and insignificantly lower at the 8th day; and osteopontin expression was remarkably lower at the 4th, 6th, and 8th days, compared with the normal control and the treatment groups (P<0.05, P<0.01). CONCLUSIONS COH might influence the sequential expressions of integrinβ3 and its ligand osteopontin, bring forward the integrinβ3 expression peak, impact on the cooperation of integrinβ3 and osteopontin, so as to damage the endometrial receptivity. ETG could regulate the sequential expressions of integrinβ3 and its ligand osteopontin to improve the mouse endometrial receptivity during COH.
