Objective:To compare the embryo development potential and clinical outcomes between the patients with and without oocyte degeneration.Methods:This retrospective cohort study included a total of 242 cycles underwent ICSI that cultured in time-lapse incubator from January 2019 to June 2023 at the Reproductive and Genetic Center of Suzhou Municipal Hospital and all 3 119 oocytes were evaluated. Data collection continued to February 5th,2024 until the last birthing of the study. Patients were divided into degenerated group (140 cycles) and control group (102 cycles) according to whether oocyte degenerated after ICSI. Then the embryo developmental potential and clinical outcomes were compared. Furthermore, we also investigated whether embryo morphokinetics could be different between the two groups.Results:Female age, duration of infertility, body mass index, basal follicle sitmulating hormone, basal luteinizing hormone, basal estrogen (E 2), antral follicle count, anti-Müllerian hormone, factors of infertility and source of semen were similar between the two groups ( P>0.05). E 2 on human chorionic gonadotropin triggered day [2 513.00 (1 842.20, 3 638.50) ng/L], number of oocytes retrieved (13.56±4.80) and oocyte maturation rate [84.35% (1 601/1 898)] were significantly higher in degenerated group than those in control group [2 270.50 (1 472.00, 3 044.20) ng/L, P=0.019; 11.97±4.71, P=0.011; 81.08% (990/1 221), P=0.017], while normal fertilization rate [69.33% (1 103/1 591)], day 3 (D3) good-quality embryos [57.85% (634/1 096)], blastocyst formation rate [50.87% (469/922)] and embryo utilized rate [58.30% (643/1 103)] were significantly lower in degenerated group than those in control group [85.56% (847/990), P<0.001; 65.72% (556/846), P<0.001; 61.26% (446/728), P<0.001; 66.12% (560/847), P<0.001] . In addition, the proportion of low cell number (<7) of D3 embryos [33.76% (370/1 096)] and high fragmentation (fragmentation ≥50%, fragmentation 20%-50%) of D3 embryos [10.01% (109/1 089), 18.64% (203/1 089)] in degenerated group were significantly higher than those in control group [27.19% (230/846), P=0.002; 6.06% (51/841), P=0.002; 14.15% (119/841), P=0.009], and so were the incidence of DC1 and CC [5.98% (66/1 103) vs. 2.48% (21/847), P<0.001; 2.45% (27/1 103) vs. 0.94% (8/847), P=0.013]. As regard to the utilized embryos, there were no significant differences in t5, cc2, cc3 and s2 ( P>0.05), but tPNf [22.82(21.13, 24.84) h], t2 [25.37 (23.62, 27.37) h], t3 [35.64 (33.10, 38.03) h] and t4 [36.85 (34.70, 39.52) h] in degenerated group were significantly earlier than those in control group [23.04 (21.76, 25.41) h, P=0.001; 25.91 (24.15, 28.05) h, P=0.001; 36.16 (33.11, 38.81) h, P=0.040; 37.39 (35.11, 40.27) h, P=0.026]. Further more, after the first transfer of fresh or frozen embryos, there were no significant differences in clinical pregnancy rate, implantation rate, early abortion rate, live birth rate, sex ratio, preterm birth rate, low birth weight rate and birth defect rate between the two groups (all P>0.05). ICSI degeneration was not an independent factor of implantation rate, early abortion rate and live birth rate after ICSI treatment, but number of embryos transferred was an independent factor of implantation rate and live birth rate after ICSI treatment ( OR=2.806, 95% CI: 1.179-6.677, P=0.020; OR=2.622, 95% CI: 1.129-6.090, P=0.025). Conclusion:The presence of oocyte degeneration after ICSI may affect the overall developmental potential of its sibling oocytes and may also disturb the morphokinetics of the embyos, however the pregnancy outcomes and neonatal birth outcomes may not be affected if transfer the best embryo in the first fresh or frozen cycle.

Objective:To investigate the mediating role of psychological capital between the perception of decent work and work engagement among Operating Room nurses, and to provide insights for improving their work engagement.Methods:From December 2023 to February 2024, a total of 307 Operating Room nurses from four class ⅢGrade A hospitals in Beijing, Chongqing, Dalian, and Zhuhai were recruited using convenience sampling. Data were collected using a general information questionnaire, Work Engagement Scale, Decent Work Scale, and Nurses' Psychological Capital Scale. Pearson correlation analysis was conducted to examine the relationships among psychological capital, perception of decent work, and work engagement. Structural equation modeling and mediation analysis were performed using AMOS 24.0 software.Results:A total of 307 questionnaires were distributed, and 301 valid responses were collected, with an effective response rate of 98.05%. The mean scores for work engagement, perception of decent work, and psychological capital were (41.01±10.76), (67.30±17.86), and (93.30±15.15), respectively. Work engagement was positively correlated with both the perception of decent work and psychological capital (all P<0.01), and the perception of decent work was positively correlated with psychological capital ( P<0.01). Psychological capital partially mediated the relationship between the perception of decent work and work engagement, with the mediating effect accounting for 62.63%. Conclusions:Psychological capital plays a partial mediating role between the perception of decent work and work engagement among Operating Room nurses. Nursing managers can enhance nurses' work engagement by improving their perception of decent work and strengthening their psychological capital.

A brain-computer interface (BCI) based on motor imagery (MI) provides additional control pathways by decoding the intentions of the brain. MI ability has great intra-individual variability, and the majority of MI-BCI systems are unable to adapt to this variability, leading to poor training effects. Therefore, prediction of MI ability is needed. In this study, we propose an MI ability predictor based on multi-frequency EEG features. To validate the performance of the predictor, a video-guided paradigm and a traditional MI paradigm are designed, and the predictor is applied to both paradigms. The results demonstrate that all subjects achieved > 85% prediction precision in both applications, with a maximum of 96%. This study indicates that the predictor can accurately predict the individuals' MI ability in different states, provide the scientific basis for personalized training, and enhance the effect of MI-BCI training.

OBJECTIVE: To explore the research history, hotspots and development trends of acupuncture and moxibustion in the treatment of gastroesophageal reflux disease（GERD）based on knowledge graph technology, and to provide references for clinical and basic research in this field. METHODS: The literature of acupuncture and moxibustion for gastroesophageal reflux disease was searched from the CNKI, Wanfang, VIP and SinoMed, from the establishment of the databases to December 31th, 2023. CiteSpace 6.2.R6 Advance was used to draw the knowledge graph of authors, institutions, keywords and other elements, and then perform the visual analysis. RESULTS: A total of 341 articles were included, with the number of publications showing an upward trend and the research types continually diversifying. A total of 832 authors and 308 institutions were analyzed, with XIE Sheng from the First Affiliated Hospital of Guangxi University of CM and BAI Xinghua from the Beijing University of CM as representative figures, forming core research teams. However, there was a lack of close collaboration between institutions, and no significant cross-regional research networks had been formed. A total of 192 keywords were included, forming 8 cluster labels, which mainly included 4 categories：treatment methods, disease types, TCM syndrome types, and literature types. The burst analysis showed that the methods of acupuncture and moxibustion in the treatment of gastroesophageal reflux disease had gradually become more integrated, the treatment methods had transitioned from simple acupuncture therapy to combined therapies with proton pump inhibitors or TCM decoctions, the disease types had become more refined, the focus of mechanism research had shifted from lower esophageal sphincter pressure and esophageal motility to changes in gastrointestinal hormone levels, and the research hotspots had gradually shifted from improving clinical symptoms to considering both mental and psychological states. Twenty-three high-frequency acupoints were obtained, forming 8 clusters of "acupuncture techniques-acupoints" for the treatment of gastroesophageal reflux disease with acupuncture and moxibustion, indicating a gradual enrichment of acupuncture and acupoint treatment protocols. CONCLUSION The research on acupuncture and moxibustion in the treatment of gastroesophageal reflux disease has gradually deepened, in the future, the cooperation among research teams should be strengthened, the quality of clinical research should be improved, more multi-dimensional mechanism research and horizontal comparative research of different acupuncture and moxibustion methods should be made, to provide a basis for clinical promotion and deeper exploration.

Objective To conduct a visual analysis of the current status, hotspots, and frontiers of research on renal cell carcinoma targeted therapy using VOSviewer software. Methods Literature related to renal cell carcinoma targeted therapy published between January 1, 2006 and December 31, 2023, from the Web of Science (WOS) Core Collection database were retrieved. Eligible articles were screened and subjected to bibliometric and visual analysis using VOSviewer software. Results A total of 1, 009 articles were selected, with an overall increasing trend in annual publication volume. The top three countries in terms of publication output were the United States, China, and Italy, while the top three institutions were Harvard University, The University of Texas, and France Uni-cancer Institute. The analysis of the core author collaboration network revealed close collaboration among researchers in the United States and the United Kingdom, whereas collaboration between China and foreign countries was limited, resulting in a relatively loose collaboration network. Through co-occurrence clustering analysis of high-frequency author keywords, nine clusters were generated, with hotspots focusing on targeted and immune combination therapy, efficacy, prognosis, drug resistance, targets, and biomarkers. Conclusion Remarkable progress has been made in renal cell carcinoma targeted therapy research over the past decade; however, drug resistance and adverse reactions to targeted therapies remain challenges in clinical treatment. Research related to targeted drug resistance mechanisms, novel targeted drugs, and effective predictive biomarkers has significantly increased. Grasping the developmental trends in this fieldis crucial, and VOSviewer's visual analysis can offer an intuitive representation of the current status, hotspots, and frontiers, thereby providing researchers with a valuable reference.

【Objective】 To explore the effectiveness of an image recognition system based on artificial intelligence (AI) in diagnosing benign and malignant endometrial cell clumps. 【Methods】 We selected endometrial cytological specimens from The First Affiliated Hospital of Xi’an Jiaotong University and Xi’an Daxing Hospital from August 2021 to February 2023; histopathology was used as the gold standard. We compared and analyzed the sensitivity, specificity, positive predictive value, negative predictive value, accuracy and diagnostic time of AI image recognition system (AI diagnosis) and professional pathologists’ manual diagnosis (manual diagnosis) of benign and malignant endometrial cell clumps. 【Results】 Among the 126 patients included in the analysis, the overall coincidence rate of AI diagnosis and histological diagnosis was 92.1% (116/126), which was highly consistent with histopathological results (Kappa=0.841). The overall coincidence rate of manual diagnosis and histological diagnosis was 94.4% (119/126), which was highly consistent with histopathological results (Kappa=0.889). There was no statistically significant difference between AI diagnosis and manual diagnosis methods (χ²=0.568, P=0.451). The sensitivity, specificity, positive predictive value, and negative predictive value of AI diagnosis were 91.8%, 92.3%, 91.8%, and 92.3%, respectively. There were 126 cytology sections, each of which required 6.67 minutes for manual diagnosis and 5.00 minutes for AI diagnosis. 【Conclusion】 The AI image recognition system has high diagnostic accuracy, sensitivity and specificity, which is equivalent to the manual diagnosis level of professional pathologists. Therefore, this system has application value in the diagnosis of benign and malignant endometrial cell clumps.
