Abstract
Although most pregnancies result in a good outcome, complications are not uncommon and can be associated with serious implications for mothers and babies. Predictive modeling has the potential to improve outcomes through a better understanding of risk factors, heightened surveillance for high-risk patients, and more timely and appropriate interventions, thereby helping obstetricians deliver better care. We identify and study the most important risk factors for four types of pregnancy complications: (i) severe maternal morbidity, (ii) shoulder dystocia, (iii) preterm preeclampsia, and (iv) antepartum stillbirth. We use an Explainable Boosting Machine (EBM), a high-accuracy glass-box learning method, for the prediction and identification of important risk factors. We undertake external validation and perform an extensive robustness analysis of the EBM models. EBMs match the accuracy of other black-box ML methods, such as deep neural networks and random forests, and outperform logistic regression, while being more interpretable. EBMs prove to be robust. The interpretability of the EBM models reveal surprising insights into the features contributing to risk (e.g., maternal height is the second most important feature for shoulder dystocia) and may have potential for clinical application in the prediction and prevention of serious complications in pregnancy.

Abstract
OBJECTIVES Systematic reviews (SRs) are becoming essential evidence in the decision-making process within the field of social sciences. This study aimed to investigate how Campbell SRs were cited and explore their specific application roles. STUDY DESIGN AND SETTING We included Campbell SRs published between 2016 and 2020 by searching the Wiley online library, and retrieved the articles and documents citing Campbell SRs from the Web of Science and Google Scholar by December 31, 2021. We described the characteristics of the SRs and citations, and formulated a set of application roles by analyzing the sentences or paragraphs where the SRs were cited. RESULTS Sixty nine Campbell SRs were published between 2016 and 2020; they were cited in 641 articles or documents a total of 1,289 times. The primary types of articles that cited Campbell SRs were cross-sectional studies (n = 226, 35.3%), SRs (n = 112, 17.5%), randomized controlled trials (n = 77, 12.0%), and policy reports (n = 57, 8.8%). Articles utilizing Campbell SRs were predominantly led by authors from the United States (n = 184, 28.7%), the United Kingdom (n = 98, 15.3%), and Australia (n = 51, 8.0%). We formulated a set of 10 application roles for the Campbell SRs, of which the most frequent were: describing the current status in the field of interest (n = 691, 53.6%), corroboration of the results (n = 140, 10.9%), identifying research gaps (n = 130, 10.1%), and providing methodological references (n = 126, 9.8%); the role of supporting policy recommendations or decisions accounted for 6.0% (n = 77) of the citations. Approximately 12% of Campbell SRs were used to support policy recommendations or decisions. CONCLUSION Campbell SRs are widely applied, particularly in scientific research, to describe the current status in the field of interest. Although the current application of Campbell SRs in supporting policy recommendations and decisions may not be predominant, there is a growing recognition of their value in using Campbell SRs to inform decision-making.

Abstract
BACKGROUND The detection of circulating tumor cells (CTCs) has been employed in prognosticating the likelihood of recurrence and metastasis in colorectal cancer (CRC). Nonetheless, the findings remain enigmatic. This meta-analysis aims to systematically assess the predictive utility of CTCs detection in postoperative recurrence and metastasis among CRC patients. METHODS A comprehensive search of PubMed, Web of Science, China National Knowledge Infrastructure (CNKI), and Cochrane Library was conducted from inception to March 2023. Pooled estimates including sensitivity, specificity, positive and negative likelihood ratios, diagnostic odds ratio, and summary receiver operating characteristic curve were computed to gauge the predictive value. The QUADAS-2 tool was employed to appraise bias risks in individual studies. The assessment of publication bias in the included literature was performed using Deek's funnel plot. RESULTS The study encompassed 16 articles and 2037 patients. After synthesizing the pertinent indices, CTCs monitoring demonstrated sensitivity and specificity of 0.71 (95% confidence interval [CI], 0.62-0.79) and 0.71 (95% CI, 0.55-0.83), respectively. The corresponding values for positive likelihood ratio, negative likelihood ratio, and diagnostic odds ratio were 2.4 (95% CI, 1.5-4.0), 0.41 (95% CI, 0.29-0.58), and 6 (95% CI, 3-13). The summary receiver operating characteristic curve yielded an area under the curve of 0.76 (95% CI, 0.72-0.80). Deek's funnel plot analysis revealed no significant evidence of publication bias (P = .42). CONCLUSION This investigation underscores the potential of CTCs detection as a noninvasive modality to efficaciously prognosticate postoperative recurrence and metastasis in CRC.

Abstract
Objective To analyze the association between persistent human papillomavirus (HPV) infection and vaginal microecological imbalance after surgical treatment of cervical high-grade squamous intraepithelial lesion (HSIL). Methods This is a retrospective study, 180 cervical HSIL patients admitted to our hospital from May 2019 to May 2021 were selected, of these, 84 were treated with loop electrosurgical excision procedure (LEEP) and 96 with cold knife conization (CKC). Patients were followed up for HPV infection 1 year after surgery. There is a division into a persistent infection group (positive group) and a negative group based on the presence or absence of HPV, the detection technique was PCR amplification. The two groups were compared regarding preoperative HPV infection, vaginal micro-ecological indicators 1 year after surgery, and the correlation between persistent HPV infection and vaginal microecological imbalance. Results At 1 year after surgery, among 180 cervical HSIL patients, 64 (35.56%) were persistently infected with HPV, with an age of (40.20 ± 4.85) years, including 36 (56.25%) with cervical intraepithelial neoplasia (CIN) grade II, 28 (43.75%) with cervical intraepithelial neoplasia (CIN) grade III, 116 (64.44%) with HPV negative, with an age of (40.22 ± 5.15) years, including 67 (57.76%) with CIN grade II and 49 (42.24%) with CIN grade III, the differences in age and CIN classification between the two groups were not statistically significant (P > .05). Preoperatively, 53 people (82.81%) with HPV viral load >100 RLU/CO in the HPV persistent infection group and 76 people (65.52%) with HPV viral load >100 RLU/CO in the HPV negative group, with statistically significant differences between the two groups (P < .05); The difference in HPV virus typing and HPV infection type between the two groups was not statistically significant (P > .05). At 1 year after surgery, the composition ratio of flora density class IV and flora diversity class IV were significantly higher in the HPV persistent infection group than in the HPV negative group, and the dominant bacteria were mainly gram-positive large bacillus, accounting for 83.33%, the difference between the two groups was statistically significant (P < .05); The differences in Nugent scores and pH values between the two groups were not statistically significant (P > .05). Logistic regression analysis showed that flora density, flora diversity, and dominant bacteria were all independent risk factors for persistent HPV infection after treatment in patients with HSIL (P < .05). Conclusion After treatment of HSIL patients, clinical attention should be paid to monitoring of HPV infection but also to the changes in vaginal microecology, as timely correction of vaginal microecology can facilitate HPV regression and improve the patient's prognosis.

Abstract
INTRODUCTION Emergency cesarean section is one of the most critical methods in the treatment of high-risk emergency obstetric cases. The aim of this study was to explore the clinical effect of constructing a Rapid Response Team (RRT) in emergency cesarean section. METHODS This is a pre- and post-implementation study. The patients who underwent emergency cesarean section were retrospectively analyzed and divided into an experimental group and a control group. There were 52 patients (June-December 2020) in the control group who underwent routine emergency cesarean section without an RRT, and 51 patients (January-June 2021) in the experimental group who underwent emergency cesarean section with an RRT. The operation time indexes (DOI, decision-to-operating room interval; O-I, operating room-to-incision interval; DII, decision-to-incision interval; I-D, incision-to-delivery interval; DDI, decision-to-delivery interval), DDI pass rate, neonatal Apgar score and maternal complications in the two groups were compared. Moreover, the management time trends (DOI, DII, and DDI) in the experimental group were analyzed. RESULTS The DDI, DII, DOI, and O-I of the experimental group were shorter than those of the control group, and the differences were significant (p < 0.05). The DDI pass rate in the experimental group was higher than that in the control group, and the difference was significant (p < 0.01). The 1-min Apgar score of the experimental group was higher than that of the control group (p < 0.05). The key intervals of emergency cesarean section in the experimental group leveled off after approximately 3 to 4 months. CONCLUSION In the face of emergency situations, the implementation of an emergency cesarean section RRT can improve delivery intervals for emergency cesarean and would be conducive to maternal and infant safety.

Abstract
BACKGROUND Daylength is a key seasonal cue for animals and plants. In cereals, photoperiodic responses are a major adaptive trait, and alleles of clock genes such as PHOTOPERIOD1 (PPD1) and EARLY FLOWERING3 (ELF3) have been selected for in adapting barley and wheat to northern latitudes. How monocot plants sense photoperiod and integrate this information into growth and development is not well understood. RESULTS We find that phytochrome C (PHYC) is essential for flowering in Brachypodium distachyon. Conversely, ELF3 acts as a floral repressor and elf3 mutants display a constitutive long day phenotype and transcriptome. We find that ELF3 and PHYC occur in a common complex. ELF3 associates with the promoters of a number of conserved regulators of flowering, including PPD1 and VRN1. Consistent with observations in barley, we are able to show that PPD1 overexpression accelerates flowering in short days and is necessary for rapid flowering in response to long days. PHYC is in the active Pfr state at the end of the day, but we observe it undergoes dark reversion over the course of the night. CONCLUSIONS We propose that PHYC acts as a molecular timer and communicates information on night-length to the circadian clock via ELF3.

Abstract
BACKGROUND The timely identification of patients at risk of acute kidney injury (AKI), along with early prevention, real-time monitoring, and prompt intervention, plays a crucial role in enhancing patient prognosis after major surgery. METHODS We conducted a comprehensive search across multiple databases, including Web of Science, EMBASE, MEDLINE, China National Knowledge Infrastructure, and Cochrane Library. Each study's risk of bias was independently evaluated as low, moderate, or high, utilizing criteria adapted from Quality Assessment of Diagnostic Accuracy Studies 2. The analysis was performed using STATA V.17.0 and R software V.3.4.1. Diagnostic tests were ranked based on the dominance index. We performed meta-analyses to calculate odds ratios (ORs) and 95% confidence intervals (CIs) individually. We then carried out a network meta-analysis to compare the performances of these biomarkers. RESULTS Fifteen studies were included in this analysis. The meta-analysis findings revealed that among all the biomarkers assessed, serum cystatin C (s-CysC) (hierarchical summary receiver operating characteristic curve [HSROC] 82%, 95% CI 0.78-0.85) exhibited the highest HSROC value. The network meta-analysis demonstrated that urinary kidney injury molecule-1 (u-KIM-1) and s-CysC displayed relatively higher sensitivity and specificity, respectively. In subgroup analyses, u-KIM-1 in the urine output (OU) group (OR 303.75, 95% CI 3.39-1844.88), s-CysC in the non-OU group (OR 10.31, 95% CI 3.09-26.2), interleukin-18 in the noncardiac surgery group (OR 46.20, 95% CI 0.48-307.68), s-CysC in the cardiac group (OR 12.42, 95% CI 2.9-35.86), u-KIM-1 in the retrospective group (OR 243.00, 95% CI 1.73-1582.11), and s-CysC in the prospective group (OR 8.35, 95% CI 2.34-21.15) had the best diagnostic accuracy. However, it is important to note that existing publication bias may reduce the reliability of the above-mentioned results. CONCLUSION The biomarker of s-CysC has the highest HSROC value to predicting acute kidney injury after major surgery in meta-analysis and relatively higher specificity in network meta-analyses. u-KIM-1 exhibited relatively higher sensitivity, with best diagnostic accuracy in the OU and retrospective group in the subgroup analysis.

Abstract
Objective: To clarify the definition of severe pulmonary tuberculosis and its inclusion criteria by summarizing and analyzing the studies of severe pulmonary tuberculosis (TB). Methods: A systematic search of Medline (via PubMed), Cochrane Library, Web of Science, Web of Science, Epistemonikos, Embase, CNKI, WanFang database, and CBM database was conducted to collect studies published between 2017 and 2022 on patients with severe pulmonary TB. Searches were performed using a combination of subject terms and free words. The search terms included: tuberculosis, severe, serious, intensive care, critical care, respiratory failure, mechanical ventilation, hospitalization, respiratory distress syndrome, multiple organ failure, pulmonary heart disease, and pneumothorax. The definitions and inclusion criteria for severe pulmonary TB in the included studies were extracted. Results: A total of 19 981 studies were identified and 100 studies were finally included, involving 8 309 patients with severe pulmonary TB. A total of 8 (8.00%) studies explicitly mentioned the definition of severe pulmonary TB, and 53 (53.00%) studies clearly defined the inclusion criteria for patients with severe pulmonary TB. A total of 5 definitions and 30 inclusion criteria were extracted. A total of 132 dichotomous variables and 113 continuous variables were included in the outcome indicators related to patients with severe pulmonary TB of concern in the studies. Conclusions: The definition and diagnostic criteria for severe TB are unclear, and there is an urgent need to develop a clear definition and diagnostic criteria to guide clinical practice.

Abstract
This study investigated the effects of Lacticaseibacillus paracasei K56 (L. paracasei K56) on body weight, body composition, and glycolipid metabolism in mice with high-fat diet-induced obesity and explored the underlying mechanisms. Male C57BL/6J mice were fed a high-fat diet for 8 weeks to induce obesity; then, the obese mice were gavaged with or without L. paracasei K56 for 10 weeks. The body weight, body composition, fat mass, blood lipid, blood glucose, and hormones of the mice were evaluated. Moreover, the fatty acid synthesis (FAS) and peroxisome proliferator-activated receptor γ (PPAR-γ) expressions in the liver were detected via Western blotting. 16S rRNA gene sequencing was adopted to determine the gut microbiota alterations. The high-fat diet successfully induced obesity, as indicated by the abnormal increase in body weight, visceral fat, fat mass, blood lipids, fasting blood glucose, and insulin-resistance. Moreover, the FAS expression in the liver was significantly increased, whereas the PPAR-γ expression was significantly decreased. The relative abundance of Proteobacteria, Actinobacteria and Patescibacteria was also significantly increased, and that of Verrucomicrobia was significantly decreased. However, these indicators of mice supplemented with L. paracasei K56 were significantly opposite to those of obese mice. The Ruminococcuaceae_UCG-013, Akkermansia, Prevotellaceae_UCG-001, Muribaculum, and Lachnospiraceae_NK4A136 groups were significantly negatively correlated with body weight, blood lipids, and blood glucose-related indicators, whereas Coriobacteriaceae_UCG-002, Enterorhabdus, Raoultibacter, Acinetobacter, Romboutsia, Leuconostoc, and Erysipelatoclostridium were significantly positively correlated with these indicators. L. paracasei K56 might be a promising probiotic strain that could effectively slow down the body weight gain, reduce fat accumulation, alleviate insulin-resistance, and restore pancreatic β-cell function in obese mice by regulating the gut microbiota.

Abstract
The development of new antitumor drugs depends mainly upon targeting tumor cells precisely. Trophoblast surface antigen 2 (Trop-2) is a type I transmembrane glycoprotein involved in Ca2+ signaling in tumor cells. It is highly expressed in various tumor tissues than in normal tissues and represents a novel and promising molecular target for caner targeted therapy. Up to now, the mechanisms and functions associated with Trop-2 have been extensively studied in a variety of solid tumors. According to these findings, Trop-2 plays an important role in cell proliferation, apoptosis, cell adhesion, epithelial-mesenchymal transition, as well as tumorigenesis and tumor progression. In addition, Trop-2 related drugs are also being developed widely. There are a number of Trop-2 related ADC drugs that have demonstrated potent antitumor activity and are currently been studied, such as Sacituzumab Govitecan (SG) and Datopotamab Deruxtecan (Dato-Dxd). In this study, we reviewed the progress of Trop-2 research in solid tumors. We also sorted out the composition and rationale of Trop-2 related drugs and summarized the related clinical trials. Finally, we discussed the current status of Trop-2 research and expanded our perspectives on its future research directions. Importantly, we found that Trop-2 targeted ADCs have great potential for combination with other antitumor therapies. Trop-2 targeted ADCs can reprogramme tumor microenvironment through multiple signaling pathways, ultimately activating antitumor immunity.

Abstract
Objectives To systematically analyze the use of evidence assessment tools in systematic reviews of management and education. Study design and setting We systematically searched selected literature databases and websites to identify systematic reviews on management and education. We extracted general information of the included studies and information about the evidence assessment tool they applied, including whether it was used for methodological quality assessment, reporting quality assessment or evidence grading, as well as the name, reference, publication year, version and original intended use of the tool, the role of the tool in the systematic review, and whether the quality determination criteria were given. Results A total of 299 systematic reviews were included, of which only 34.8% used evidence assessment tools. A total of 66 different evidence assessment tools were used, of which Risk of Bias (ROB) and its updated version (n = 16, 15.4%) were the most frequent. The specific roles of the evidence assessment tools were reported clearly in 57 reviews, and 27 reviews used two tools. Conclusion Evidence assessment tools were seldom used in systematic reviews in social sciences. The understanding and reporting of evidence assessment tools among the researchers and users still needs improvement.

Abstract
Objective To explore the changes in college students' awareness of health protection under the normalization of COVID-19, and to seek its connection with the epidemic management in colleges and universities, so as to provide reference information for continuous health education activities and the cultivation of college students' health emergency literacy in colleges and universities. Methods Qualitative interviews were used to understand the extent of health emergency literacy among college students enrolled in the context of a normalized epidemic and the factors associated with it that cause changes around a question outline. Results The interviewees generally had a lax mentality in the late stage of the interview, the importance they attached to epidemic prevention and control decreased significantly, and the way to know about epidemic protection measures and other knowledge was mainly through the mass news media. All respondents affirm the importance of social software for outbreak prevention and control. All 17 interviewees were able to mention basic outbreak protection methods, but 15 of them showed inconsistent behavior in words and actions later. Conclusion The vast majority of respondents' health emergency literacy appears to weaken in the late stages of epidemic normalization, and the effect of traditional approaches used by universities to improve college students' health emergency literacy is weak.

Abstract
Objectives To systematically explore how the sources of evidence, types of primary studies, and tools used to assess the quality of the primary studies vary across systematic reviews (SRs) in public health. Methods We conducted a methodological survey of SRs in public health by searching the of literature in selected journals from electronic bibliographic databases. We selected a 10% random sample of the SRs that met the explicit inclusion criteria. Two researchers independently extracted data for analysis. Results We selected 301 SRs for analysis: 94 (31.2%) of these were pre-registered, and 211 (70.1%) declared to have followed published reporting standard. All SRs searched for evidence in electronic bibliographic databases, and more than half (n = 180, 60.0%) searched also the references of the included studies. The common types of primary studies included in the SRs were primarily cross-sectional studies (n = 132, 43.8%), cohort studies (n = 126, 41.9%), randomized controlled trials (RCTs, n = 89, 29.6%), quasi-experimental studies (n = 83, 27.6%), case-control studies (n = 58, 19.3%) qualitative studies (n = 38, 12.6%) and mixed-methods studies (n = 32, 10.6%). The most frequently used quality assessment tools were the Newcastle-Ottawa Scale (used for 50.0% of cohort studies and 55.6% of case-control studies), Cochrane Collaboration's Risk of Bias tool (50.7% of RCTs) and Critical Appraisal Skills Program (38.5% of qualitative studies). Only 20 (6.6%) of the SRs assessed the certainty of the body of evidence, of which 19 (95.0%) used the GRADE approach. More than 65% of the evidence in the SRs using GRADE was of low or very low certainty. Conclusions SRs should always assess the quality both at the individual study level and the body of evidence for outcomes, which will benefit patients, health care practitioners, and policymakers.

Abstract
BACKGROUND At the 74th World Health Assembly, the World Health Organization (WHO) issued a strategy for the prevention and control of several major infectious diseases. To achieve the WHO-initiated targets for these infectious diseases, the elimination of mother-to-child transmission is essential. To date, a systematic review of the global and regional prevalence of infections with relevant mother-to-child transmission and outside the spectrum of congenital infections is lacking. OBJECTIVES We aimed to systematically review the prevalence of HIV, HBV, HCV and syphilis in pregnant women. DATA SOURCES MEDLINE, Embase, The Cochrane Library, Web of Science, China National Knowledge Infrastructure, WanFang database and China Biology Medicine disc database, and five WHO Regional Index Medicus databases. STUDY ELIGIBILITY CRITERIA Original studies reporting the prevalence of infection or co-infection of HIV, HBV, HCV and syphilis in pregnant women. METHODS This systematic review was followed the PRISMA 2020 checklist. We used random-effects models to generate pooled prevalence estimates for each infection. RESULTS Global pooled prevalence in pregnant women of HIV, HBV, HCV, and syphilis was 2.9% (95%CI 2.5-3.5%), 4.7% (3.8-5.7%), 1.0% (0.8-1.3%), and 0.8% (0.7-0.9%). The pooled prevalence of HIV, HBV, HCV, and syphilis in low-income countries was higher than the global level (HIV: 5.2% (1.6-10.5%); HBV: 6.6% (5.4-7.9%); HCV: 2.7% (1.6-4.1%); syphilis: 3.3% (2.2-4.6%)). The pooled prevalence of HIV, HBV, HCV, and syphilis in lower-middle-income countries was higher than the global level (HIV: 2.9% (0.8-6.1%); HBV: 4.9% (3.8-6.1%); HCV: 2.3% (1.2-3.6%); syphilis: 1.5% (1.0-2.2%)). CONCLUSIONS The prevalence of these infections among pregnant women was particularly high in resource-poor settings. The relevance and feasibility of current global practice guidelines for prevention of mother-to-child transmission of these infections for lower-middle-income countries must be evaluated, including timely access to screening and therapeutics.

Abstract
The hidden Markov model (HMM) is a broadly applied generative model for representing time-series data, and clustering HMMs attract increased interest from machine learning researchers. However, the number of clusters ( K ) and the number of hidden states ( S ) for cluster centers are still difficult to determine. In this article, we propose a novel HMM-based clustering algorithm, the variational Bayesian hierarchical EM algorithm, which clusters HMMs through their densities and priors and simultaneously learns posteriors for the novel HMM cluster centers that compactly represent the structure of each cluster. The numbers K and S are automatically determined in two ways. First, we place a prior on the pair (K,S) and approximate their posterior probabilities, from which the values with the maximum posterior are selected. Second, some clusters and states are pruned out implicitly when no data samples are assigned to them, thereby leading to automatic selection of the model complexity. Experiments on synthetic and real data demonstrate that our algorithm performs better than using model selection techniques with maximum likelihood estimation.

Abstract
BACKGROUND Acute ischemic stroke (AIS) occurs due to brain ischemia as a result of thrombosis of a cerebral blood vessel. It is a common cerebral blood circulation disorder worldwide and an important cause of death and disability. OBJECTIVE This study aims to establish a prediction model of multiple single category indicators and a joint model, through which to plot multiple receiver operating characteristic curves and compare area under curve of the models so as to predict the occurrence of AIS, explore the pathogenesis of AIS, and provide reference for clinical diagnosis and treatment of AIS. METHODS A retrospective clinical study was conducted in a Level A tertiary hospital in Sichuan Province, China. The patients participated in this study were over 18 years of age and suffered from acute ischemic stroke. They were hospitalized in department of neurology from October 1, 2019 to September 30, 2022, and underwent coronary artery computed tomographic arteriography (CTA) and blood biomarker detection. We collected demographic information, CTA data and blood biomarker detection values of all these patients. CONCLUSION Through analyzing the clinical data of high-risk groups, this study provides guidance for the prevention and treatment of AIS, and promote further research.

Abstract
OBJECTIVE To explore the application effect of the clinical basic integration teaching mode constructed by case studies and the MOOC platform in obstetrics and gynecology internship teaching in the face of public health emergencies. METHODS One hundred ten clinical medical students of grade 2020 were selected as the experimental group, and 110 clinical medical students of grade 2021 were selected as the control group. The experimental group adopted the online teaching mode combined with case studies and the MOOC platform, while the control group adopted the offline traditional probation teaching method. Comprehensive test and questionnaire were used to evaluate and compare the teaching effect of the two groups of students. RESULTS The experimental group was found to be superior to the control group in the quality assessment of complete medical record writing and the ability assessment of diagnosis and analysis of typical obstetrics and gynecology cases (P < 0. 05). However, the score of professional knowledge was lower than that of the control group (P < 0. 05). The results of questionnaire survey showed that the satisfaction of the experimental group in stimulating learning interest, enhancing problem solving ability, enhancing communication and clinical thinking ability, enhancing team cooperation awareness and independent innovation ability was higher than that of the control group (P < 0.01). The satisfaction of teacher-student interaction was also better (P < 0.05). However, in terms of strengthening theoretical understanding, the satisfaction of the experimental group was lower than that of the control group, but with no significant difference (P > 0.05). CONCLUSION During the epidemic period, we designed a new online teaching mode, which can be applied to the probation teaching of obstetrics and gynecology. In our study, compared with traditional offline teaching, the new online teaching mode could improve students' ability of case writing and case analysis. However, more teaching practice is needed to complete this online teaching mode.

Abstract
Purpose This study evaluates the content, distribution, and changing trend of sialic acid in human milk and the correlation between dietary intake of sialic acid and that in human milk. Methods The study included 33 mothers of full-term and exclusively breastfed infants. At least 2 ml of milk was collected on the 3rd, 8th, 30th, and 90th day after delivery, and 24-h diet recalls of the lactating mothers were obtained each time. The correlation of human milk sialic acid concentration with lactating women's dietary sialic acid intake during lactation was analyzed by statistical analysis software SPSS. Results The average concentration of sialic acid in colostrum, transition, and 1 and 3 months were 1,670.74 ± 94.53, 1,272.19 ± 128.74, 541.64 ± 55.2, and 297.65 ± 20.78 mg/L, respectively. The total sialic acid concentration in colostrum was about 5.6 times higher than that at 3 months (P < 0.001). The average dietary sialic acid intake of lactating mothers on the 2nd, 7th, 30th, and 90th day after delivery were 106.06 ± 7.51, 127.64 ± 8.61, 120.34 ± 10.21, and 95.40 ± 6.34 mg/day, respectively. The intake of sialic acid was relatively high on the 7th day, and there was no significant difference in dietary intake of sialic acid on different days (P < 0.05). In addition, there was no correlation between the intake of dietary sialic acid and the content of total sialic acid and various forms of sialic acid in milk (P < 0.05). Conclusion During the lactation period, the distribution of sialic acid in breast milk is relatively stable and its content fluctuates greatly, which may not be affected by the mother's diet, but mainly depends on the self-regulation oft physiological needs.

Abstract
Objectives This study aims to investigate the risk of COVID-19 transmission on aircraft. Methods We obtained data on all international flights to Lanzhou, China, from June 1, 2020, to August 1, 2020, through the Gansu Province National Health Information Platform and the official website of the Gansu Provincial Center for Disease Control and Prevention. We then performed the statistical analysis. Results Three international flights arrived in Lanzhou. The flights had a total of 700 passengers, of whom 405 (57.9%) were male, and 80 (11.4%) were children under the age of 14 years. Twenty-seven (3.9%) passengers were confirmed to have COVID-19. Confirmed patients were primarily male (17, 65.4%) with a median age of 27.0 years. Most confirmed cases were seated in the middle rows of economy class or near public facility areas such as restrooms and galleys. The prevalence of COVID-19 did not differ between passengers sitting in the window, aisle, or middle seats. However, compared with passengers sitting in the same row up to 2 rows behind a confirmed case, passengers seated in the 2 rows in front of a confirmed case were at a slightly higher risk of being infected. Conclusions COVID-19 may be transmitted during a passenger flight, although there is still no direct evidence.

Abstract
Patients diagnosed with inflammatory bowel disease or related conditions also frequently suffer from osteoporosis as a consequence of changes in the intestinal microenvironment and consequent dysbiosis. We hypothesized that anti-inflammatory probiotic treatment would be sufficient to alleviate intestinal inflammation and thereby prevent the development of osteoporosis. To that end, the ability of Bifidobacterium lactis BL-99 administration to protect against bone loss in an experimental model of dextran sodium sulfate-induced ulcerative colitis (UC) was analyzed, and the underlying molecular mechanisms were interrogated in detail. The results of these analyses revealed that BL-99 administration suppressed colitis-associated weight loss (P < 0.05), disease activity index scores, and the production of proinflammatory cytokines (TNF-α, IL-1β, IL-6, and IL-17) (P < 0.05). Colon tissue pathological sections similarly revealed BL-99-mediated reductions in tissue injury severity. Micro-computed tomography (Micro-CT) analyses further exhibited significant improvements in percent bone volume (BV/TV) as well as trabecular number and thickness in BL-99-treated animals (P < 0.05). Such probiotic supplementation also resulted in pronounced changes in the composition of the gut microbiota. Moreover, BL-99 intervention markedly increased the expression of intestinal barrier-related proteins (Claudin-1, MUC2, ZO-1, and Occludin). Together, these results suggest that BL-99 can be utilized as a beneficial probiotic preparation to prevent the incidence of osteoporosis in UC patients owing to its ability to shape the intestinal microflora and to suppress inflammatory cytokine production.

Abstract
Severe Coronavirus Disease 2019 (COVID-19) is characterized by numerous complications, complex disease, and high mortality, making its treatment a top priority in the treatment of COVID-19. Integrated traditional Chinese medicine (TCM) and western medicine played an important role in the prevention, treatment, and rehabilitation of COVID-19 during the epidemic. However, currently there are no evidence-based guidelines for the integrated treatment of severe COVID-19 with TCM and western medicine. Therefore, it is important to develop an evidence-based guideline on the treatment of severe COVID-19 with integrated TCM and western medicine, in order to provide clinical guidance and decision basis for healthcare professionals, public health personnel, and scientific researchers involved in the diagnosis, treatment, and care of COVID-19 patients. We developed and completed the guideline by referring to the standardization process of the "WHO handbook for guideline development", the Grading of Recommendations Assessment, Development and Evaluation (GRADE) system, and the Reporting Items for Practice Guidelines in Healthcare (RIGHT).

Abstract
1. A better understanding of intestinal development is essential for the intestinal health of poultry. Intestinal villification starts on embryo day E15 and is generally completed before hatching (E21). The development of lymphoid organs in the intestine starts during embryogenesis. However, transcriptional information on the processing of intestinal morphogenesis and immune development during chick embryogenesis is limited.2. In this work, RNA-sequencing was performed using 12 biological replicates to investigate Hy-Line brown chick embryonic small intestinal transcription at E15 and E21. Differentially expressed genes (DEGs) between E15 and E21 were identified. GO and KEGG enrichment analyses, based on the DEGs, were performed to identify key GO terms in the biological process category and key KEGG pathways. PPI networks were constructed based on the DEGs in the key pathways to screen hub genes. The embryonic small intestinal morphology and IgA distribution were observed by histological processing. The serum levels of IgA and lysozyme were measured by ELISA.3. A total of 76.38 Gb of high-quality RNA-sequencing data were generated and uploaded. A total of 2,676 DEGs, between E15 and E21, were identified. Structural development and villification of the small intestine at E15 tended to proceed via the expression of nervous system development-related genes. A combination of the histological and serological results with the transcriptome data indicated that the identified genes and pathways may be strong candidates for intestinal morphogenesis-regulation.4. The small intestine appears to have developed a relatively complete morphology and transport, metabolism, digestion and immunity functions by E21. This work provided a transcriptome profile of the chick embryonic small intestine and provided insights into the intestinal development and health of poultry.

Abstract
Background Hundreds of coronavirus disease 2019 (COVID-19) clinical practice guidelines (CPGs) and expert consensus statements have been developed and published since the outbreak of the epidemic. However, these CPGs are of widely variable quality. So, this review is aimed at systematically evaluating the methodological and reporting qualities of COVID-19 CPGs, exploring factors that may influence their quality, and analyzing the change of recommendations in CPGs with evidence published. Methods We searched five electronic databases and five websites from 1 January to 31 December 2020 to retrieve all COVID-19 CPGs. The assessment of the methodological and reporting qualities of CPGs was performed using the AGREE II instrument and RIGHT checklist. Recommendations and evidence used to make recommendations in the CPGs regarding some treatments for COVID-19 (remdesivir, glucocorticoids, hydroxychloroquine/chloroquine, interferon, and lopinavir-ritonavir) were also systematically assessed. And the statistical inference was performed to identify factors associated with the quality of CPGs. Results We included a total of 92 COVID-19 CPGs developed by 19 countries. Overall, the RIGHT checklist reporting rate of COVID-19 CPGs was 33.0%, and the AGREE II domain score was 30.4%. The overall methodological and reporting qualities of COVID-19 CPGs gradually improved during the year 2020. Factors associated with high methodological and reporting qualities included the evidence-based development process, management of conflicts of interest, and use of established rating systems to assess the quality of evidence and strength of recommendations. The recommendations of only seven (7.6%) CPGs were informed by a systematic review of evidence, and these seven CPGs have relatively high methodological and reporting qualities, in which six of them fully meet the Institute of Medicine (IOM) criteria of guidelines. Besides, a rapid advice CPG developed by the World Health Organization (WHO) of the seven CPGs got the highest overall scores in methodological (72.8%) and reporting qualities (83.8%). Many CPGs covered the same clinical questions (it refers to the clinical questions on the effectiveness of treatments of remdesivir, glucocorticoids, hydroxychloroquine/chloroquine, interferon, and lopinavir-ritonavir in COVID-19 patients) and were published by different countries or organizations. Although randomized controlled trials and systematic reviews on the effectiveness of treatments of remdesivir, glucocorticoids, hydroxychloroquine/chloroquine, interferon, and lopinavir-ritonavir for patients with COVID-19 have been published, the recommendations on those treatments still varied greatly across COVID-19 CPGs published in different countries or regions, which may suggest that the CPGs do not make sufficient use of the latest evidence. Conclusions Both the methodological and reporting qualities of COVID-19 CPGs increased over time, but there is still room for further improvement. The lack of effective use of available evidence and management of conflicts of interest were the main reasons for the low quality of the CPGs. The use of formal rating systems for the quality of evidence and strength of recommendations may help to improve the quality of CPGs in the context of the COVID-19 pandemic. During the pandemic, we suggest developing a living guideline of which recommendations are supported by a systematic review for it can facilitate the timely translation of the latest research findings to clinical practice. We also suggest that CPG developers should register the guidelines in a registration platform at the beginning for it can reduce duplication development of guidelines on the same clinical question, increase the transparency of the development process, and promote cooperation among guideline developers all over the world. Since the International Practice Guideline Registry Platform has been created, developers could register guidelines prospectively and internationally on this platform.

Abstract
Light perception at dawn plays a key role in coordinating multiple molecular processes and in entraining the plant circadian clock. The Arabidopsis mutant lacking the main photoreceptors, however, still shows clock entrainment, indicating that the integration of light into the morning transcriptome is not well understood. In this study, we performed a high-resolution RNA-sequencing time-series experiment, sampling every 2 min beginning at dawn. In parallel experiments, we perturbed temperature, the circadian clock, photoreceptor signaling, and chloroplast-derived light signaling. We used these data to infer a gene network that describes the gene expression dynamics after light stimulus in the morning, and then validated key edges. By sampling time points at high density, we are able to identify three light- and temperature-sensitive bursts of transcription factor activity, one of which lasts for only about 8 min. Phytochrome and cryptochrome mutants cause a delay in the transcriptional bursts at dawn, and completely remove a burst of expression in key photomorphogenesis genes (HY5 and BBX family). Our complete network is available online (http://www-users.york.ac.uk/∼de656/dawnBurst/dawnBurst.html). Taken together, our results show that phytochrome and cryptochrome signaling is required for fine-tuning the dawn transcriptional response to light, but separate pathways can robustly activate much of the program in their absence.

Abstract
Pregnancy zone protein (PZP), a member of the proteinase inhibitor I39 (‐2‐macroglobulin) family of proteins, is involved in the initiation and development of various tumors. The gene encoding PZP is hypermethylated and expressed at low levels in hepatocellular carcinoma (HCC) tissue and cells, but the function of PZP in HCC cells remains unclear. Here, we analyzed DNA methylation and mRNA expression of HCC in The Cancer Genome Atlas Liver Hepatocellular Carcinoma dataset. We identified 10 methylation‐driven genes, of which PZP was significantly hypermethylated and poorly expressed in tumor tissue. We confirmed that PZP is highly methylated and poorly expressed in HCC cell lines via quantitative real‐time PCR experiment and methylation‐specific PCR. Furthermore, PZP markedly inhibited the proliferation, invasion and migration of HCC cells. These findings may provide a basis for exploring novel therapeutic targets for HCC.

Abstract
Abstract
Aims
Short QT syndrome (SQTS), a disorder associated with characteristic electrocardiogram QT-segment abbreviation, predisposes afflicted patients to sudden cardiac death. Despite some progress in assessing the organ level pathophysiology and genetic changes of the disorder, the understanding of the human cellular phenotype and discovering of an optimal therapy has lagged due to a lack of appropriate human cellular models of the disorder. The aim of this study was to establish a cellular model of SQTS type 5 using human-induced pluripotent stem cell–derived cardiomyocytes (hiPSC-CMs) and gene-edited cell line using CRISPR/CAS9.
Methods and results
This study recruited one patient with short QT syndrome type 5 carrying a mutation in CACNb2 gene as well as one healthy control subject. We generated hiPSCs from their skin fibroblasts, and differentiated hiPSCs into cardiomyocytes (hiPSC-CMs) for physiological. Isogenic control hiPSC-CMs generated by the CRISPR/CAS9 technique were also used for the study.
The hiPSC-CMs from the patient showed a reduced calcium current (ICa-L) density and shortened action potential duration (APD) compared with healthy control hiPSC-CMs and isogenic hiPSC-CMs. Furthermore, they demonstrated abnormal rhythmic activities. Carbachol increased the arrhythmic events in SQTS significantly but not in healthy and isogenic control cells. Gene and protein expression profiling showed a decreased CACNb2 expression in SQTS cells. Quinidine prolonged the APD and abolished arrhythmic activity.
Conclusions
Patient-specific hiPSC-CMs are able to recapitulate single-cell phenotype features of SQTS type 5 and provide novel opportunities to further elucidate the cellular disease mechanism and test drug effects.

Abstract
OBJECTIVE To investigate the association of gr/gr, b2/b3 and gr/gr with b1-2/b3-4 deletions (repetitions) in the AZFc region of the Y chromosome with recurrent spontaneous abortion (RSA). METHODS Using the next-generation sequencing technology, we examined the men with indications of Y chromosome microdeletion at our center from June 2017 to March 2018 and excluded the common causes of RSA through inquiry and other related examinations. Totally, 170 cases of AZFc deletion (80 cases of gr/gr deletion, 75 cases of b2/b3 deletion, and 15 cases of gr/gr with b1-2/b3-4 deletion) were detected and included in the case group, and another 328 normal males enlisted as controls. We analyzed the correlation of Y chromosome microdeletions with the incidence rate of RSA. RESULTS The incidence rate of RSA was significantly higher in the case group than in the normal controls (28.8% [49/170] vs 13.1% [43/328], P < 0.01), 22.5% (18/80) in the gr/gr deletion cases (P < 0.05), 30.7% (23/75) in the b2/b3 deletion cases (P < 0.01), and 53.3% (8/15) in the gr/gr with b1-2/b3-4 deletion cases (P < 0.01), remarkably lower in the gr/gr than in the gr/gr with b1-2/b3-4 deletion subgroup (P < 0.05), but with no statistically significant difference between the other subgroups. CONCLUSIONS The gr/gr, b2/b3, and gr/gr with b1-2/b3-4 deletions (repetitions) in the AZFc region of the Y chromosome may cause recurrent spontaneous abortion.

Abstract
This paper presents a method of using femtosecond laser inscribed nanograting as low-loss- and high-temperature-stable in-fiber reflectors. By introducing a pair of nanograting inside the core of a single-mode optical fiber, an intrinsic Fabry-Perot interferometer can be created for high-temperature sensing applications. The morphology of the nanograting inscribed in fiber cores was engineered by tuning the fabrication conditions to achieve a high fringe visibility of 0.49 and low insertion loss of 0.002 dB per sensor. Using a white light interferometry demodulation algorithm, we demonstrate the temperature sensitivity, cross-talk, and spatial multiplexability of sensor arrays. Both the sensor performance and stability were studied from room temperature to 1000°C with cyclic heating and cooling. Our results demonstrate a femtosecond direct laser writing technique capable of producing highly multiplexable in-fiber intrinsic Fabry-Perot interferometer sensor devices with high fringe contrast, high sensitivity, and low-loss for application in harsh environmental conditions.

Abstract
Objective: To explore the correlation between dietary N-glycolylneuraminic acid (Neu5Gc) intake and chronic inflammation state of body. Methods: A total of 306 samples of 102 types of food were purchased from a supermarket in Xiamen in September 2019, including grains, meat, poultry, seafood, eggs, beans, dairy products, vegetables and fruits. The content of Neu5Gc in food was determined by liquid chromatography-mass spectrometry. A total of 500 healthy freshmen from Xiamen University were selected by using a simple random sampling method. The food frequency questionnaire was used to investigate the food intake in the past year. The food intake was corrected by 3 consecutive 24-hour recalls, and the amount of Neu5Gc intake was calculated. The concentration of anti-Neu5Gc antibody, C-reactive protein (CRP) and interleukin-6 (IL-6) in serum was detected. Spearman correlation analysis was used to explore the correlation between Neu5Gc intake and anti-Neu5Gc antibody, CRP and IL-6 levels. Results: Neu5Gc was mainly found in red meat and liquid dairy products. The contents of Neu5Gc in beef, lamb and pork were (30.32±2.84), (20.39±4.73) and (5.58±1.04) mg/kg, respectively, and in liquid milk and yogurt were (10.87±1.54) and (6.91±0.24) mg/L, respectively. The M (P25, P75) intake of Neu5Gc for all participants was 4.62 (2.20, 8.60) mg/d. The M(P25, P75) intake of Neu5Gc for males about 6.60(2.83, 10.20) was higher than that for females about [3.84 (1.84, 6.35) mg/d] (P<0.001). The M (P25, P75) of serum anti-Neu5Gc, CRP and IL-6 levels were 3.07 (2.17, 4.14) μg/ml, 0.37 (0.22, 0.87) mg/ml and 61.82 (12.23, 315.30) pg/ml, respectively. Spearman correlation analysis showed that the intake level of Neu5Gc was positively correlated with serum anti-Neu5Gc antibody, CRP and IL-6 levels, with rs values about 0.222, 0.102 and 0.126, respectively (all P values <0.05). Conclusion: Dietary Neu5Gc intake is mainly from red meat and liquid dairy products, and its intake level is positively correlated with chronic inflammatory state of body.

Abstract
In order to achieve long-pulse H-mode plasma scenario over 400 s with high heating power in the Experimental Advanced Superconducting Tokamak (EAST) device, the lower graphite divertor will be upgraded into a tungsten (W) divertor with active water cooling, which consists of the W/Cu monoblock units and the W flat-tile units as the divertor plasma facing components. As a fundamental diagnostic tool, the divertor Langmuir probe (Div-LP) diagnostic system will be upgraded accordingly. This paper presents the design of two kinds of new Div-LP systems, which are planned to be utilized on the W/Cu monoblock units and the W flat-tile units for the upgraded lower tungsten divertor, respectively, including their structures and preliminary poloidal and toroidal layouts. The Div-LP diagnostic system can measure the plasma parameters with the schemes of triple-probe, double-probe, and single-probe, to obtain the spatial and temporal distribution of plasma behavior on the divertor targets, which is useful for the discharge control and operation in EAST. In addition, the thermal analysis of the two kinds of probe assemblies is also carried out by using the three-dimensional finite element code ANSYS, which is aimed to get the optimal designs to withstand the long-pulse and high-power operation in EAST future experiments.

Abstract
Objective: To explore the characteristics and methods of different fixation methods and prevention of open knee joint fracture. Methods: The data of 86 cases of open knee joint fracture admitted from January 2002 to December 2015 in Department of Orthopaedics, Affiliated Hospital of Chengdu University were analyzed retrospectively.There were 65 males and 21 females aged of 38.6 years. There were 38 cases treated with trans articular external fixation alone, 48 cases were in the trans articular external fixation plus auxiliary limited internal fixation group. All the patients were treated according to the same three stages except for different fixation methods. Observation of external fixation and fracture fixation, fracture healing, wound healing and treatment, treatment and related factors of infection control and knee function recovery. χ(2) test was used to analyze data. Results: Eleven patients had primary wound healing, accounting for 12.8%. Seventy-five patients had two wounds healed, accounting for 87.2%. Only 38 cases of trans articular external fixator group had 31 cases of articular surface reduction, accounting for 81.6%; Five cases of trans articular external fixator assisted limited internal fixation group had 5 cases of poor reduction, accounting for 10.4%; There was significant difference between the two groups (χ(2)=44.132, P<0.05). Take a single cross joint external fixation group, a total of 23 cases of patients with infection, accounted for 60.5% of external fixation group; trans articular external fixation assisted limited internal fixation group there were 30 cases of patients with infection, accounting for the assistance of external fixator and limited internal fixation group 62.5%; There was significant difference between the two groups(χ(2)=0.035, P>0.05). Five cases of fracture nonunion cases of serious infection, patients voluntarily underwent amputation. The Lysholm Knee Scale: In the external fixation group, 23 cases were less than 50 points, accounting for 60.5%, 15 cases were more than 50 points, accounting for 39.5%, external fixation and limited internal fixation group 20 cases were less than 50 points, accounting for 41.7%, 28 cases were more than 50 points, accounting for 58.3%; There was significant difference between the two groups(χ(2)=1.279, P>0.05). Conclusions: Prevention and control of infection is a central link in the treatment of open fracture of the knee. Trans articular external fixator plus limited internal fixation is an important measure to treat open fracture of the knee-joint.

Abstract
Plants maximize their fitness by adjusting their growth and development in response to signals such as light and temperature. The circadian clock provides a mechanism for plants to anticipate events such as sunrise and adjust their transcriptional programmes. However, the underlying mechanisms by which plants coordinate environmental signals with endogenous pathways are not fully understood. Using RNA-sequencing and chromatin immunoprecipitation sequencing experiments, we show that the evening complex (EC) of the circadian clock plays a major role in directly coordinating the expression of hundreds of key regulators of photosynthesis, the circadian clock, phytohormone signalling, growth and response to the environment. We find that the ability of the EC to bind targets genome-wide depends on temperature. In addition, co-occurrence of phytochrome B (phyB) at multiple sites where the EC is bound provides a mechanism for integrating environmental information. Hence, our results show that the EC plays a central role in coordinating endogenous and environmental signals in Arabidopsis.

Abstract
OBJECTIVE To summarize the clinical outcome of totally thoracoscopic cardiac surgery for mitral valve replacement. METHODS Clinical data of 634 cases undergoing totally thoracoscopic cardiac surgery for mitral valve replacement from May 2004 to February 2016 in Department of Thoracoscopic Cardiacsurgery, Shanghai Yodak Cardiothoracic Hospital was analyzed retrospectively. There were 292 male and 342 female patients, aged from 17 to 68 years with a mean of (45±13) years. All the 634 patients had moderate-severe mitral valve stenosis and (or) incompetence, 263 patients had moderate-severe tricuspid valve incompetence, 356 patients had atrial fibrillation, 46 patients had left atrium thrombosis. Cardiopulmonary bypass was established with right femoral artery and a single 2 stage venus cannula in the right atrium. The ascending aorta was cross-clamped and the myocardium was protected by coronary perfusion with cold crystalloid cardioplegia. Totally thoracoscopic mitral valve replacement were performed. RESULTS Thirteen cases had incision expanded and 8 cases had conversions to sternotomy. Cardiopulmonary bypass and aortic cross-clamp time were (89±18) minutes and (51±12) minutes, respectively. Operation time was (3.1±1.2) hours. Mechanical ventilation time and intensive care unit stay were (17±6) hours and (27±8) hours, respectively. Postoperation drainage quantity was (390±70) ml. The hospital days was (9.2±2.1) days. There were 5 cases in-hospital deaths. Postoperative complications occurred in 42 cases (6.6%), including 18 cases of right hemoneumothorax, 12 cases of reoperation for bleeding, 3 cases of perivalvular leakage (reoperation was done in 1 patient), 3 cases of low cardiac output syndrome, 2 cases of acute renal failure, 2 cases of inferior vena cava injury, 1 case of right femoral artery thrombosis and liver injury, respectively. The mean duration of follow-up was (58±9) months in 608 cases, with a follow-up rate of 96.7% (608/629). Three patients had died during the period of follow-up caused by congestive heart failure (2 patients) and stroke (1 patient). Late complication among 605 survivors were 37 cases, including 32 cases of moderate tricuspid valve insufficiency, 3 cases of stroke, 1 case of perivalvular leakage and infective endocarditis, respectively.There was no reoperation during the period of follow-up. CONCLUSION Totally thoracoscopic cardiac surgery for mitral valve replacement is safe and effective, with unique superiority and clinical feasible.

Abstract
Effects of pre-gestational physical activity on the later development of embryos generated in vitro were evaluated. Kunming mice were divided into two groups, namely exercised and unexercised, with the former undergoing physical training on a motor-driven leveled treadmill over a period of 4weeks (5days/week and 60min/day). After that, following superovulation, collection of oocytes from both groups was performed for in vitro fertilization (IVF) and somatic cell nuclear transfer (SCNT). Notably and specifically, natural mating between the unexercised mice was also done for in vivo fertilization (IVIF). Observation on the preimplantation embryo development showed that SCNT embryos from exercised group (NEM) had significant higher rates of cleavage and formation of blastocyst containing more blastomeres compared to SCNT embryos from unexercised group (NCM); while IVF embryos in exercised group (FEM) showed a significant higher rate of cleavage and blastocyst formation. Further analysis of embryos from the trained group on the molecular level demonstrated a prominent increase in terms of ATP levels, mitochondria membrane potential (Δψm) and mtDNA copy number and an obvious decrease in H2O2 concentration than those from the respective control group. Meanwhile, epigenetically, methylation levels of CpG sites on imprinting control regions of imprinted genes (Igf2, Igf2r, Meg 3 and H19) in the NEM embryos were normalized in exercise groups compared to the NCM embryos, which were comparable to the in vivo-derived embryos. Moreover, global DNA and histone methylation (H3K4m2, H3K9m3 and H3K36m) further confirmed that NEM-derived embryos and in vivo-derived ones stay in the same cluster, indicating that physical activity in pre-pregnancy facilitates the maintenance of epigenetic modifications. Generally, these results strongly suggest that physical exercise before pregnancy is in favor of the later embryo development.
