Objective:To analyze the chromosome status of pre-implantation embryos from women of different ages, and assess the impact of age on it.Methods:A retrospective analysis was carried out on the results of PGT-A and PGT-M+ PGT-A cycles by whole-genome amplification followed by next generation sequencing at the Second People′s Hospital of Nanning between July 2021 and November 2023. The embryos were divided into five groups based on the women′s age: ≤ 30 years old group, 31 ~ 34 years old group, 35 ~ 37 years old group, 38 ~ 40 years old group, and ≥ 41 years old group. The chromosomal status of embryos for each group was compared. This study has been approved by the Ethic Committee of the Hospital (Ethics No. Y2024312A).Results:This study has involved 390 couples and 436 PGT cycles, with a total of 1 651 blastocysts biopsied and analyzed. Among these, 835 embryos (50.6%) were found to have chromosomal abnormalities, including 490 (29.7%) with aneuploidies, 154 (9.3%) with chromosomal segment abnormalities, and 264 (16.0%) with chromosome mosaicisms. After adjusting the dosages of Gn, female BMI, male age, PGT indications, infertility type, LH, AMH and other parameters, maternal age appeared to be an independent factor for chromosomal abnormalities and aneuploidies in blastocysts ( OR=1.132, 95% CI = 1.089 - 1.177, P<0.001; OR=1.250, 95% CI = 1.188-1.315, P<0.001). With the increase in female age, embryonic chromosome abnormalities have significantly increased in each group, with the rates being 32.3% (126/390), 43.1% (189/439), 45.1% (116/257), 66.3% (250/377), and 81.9% (154/188) ( P<0.001). Chromosomal aneuploidies have also significantly increased, with the rates being 8.2% (32/390), 16.6% (73/439), 24.5% (63/257), 49.6% (187/377), and 71.8% (135/188) ( P<0.001). The proportion of embryos with ≥ 2 chromosome abnormalities also significantly increased in abnormal embryos, with the rates being 28.6% (36/126), 30.2% (57/189), 39.7% (46/116), 48.4% (121/250), and 64.9% (100/154) ( P<0.001). Of note, the female age did not affect the prevalence of chromosomal segment abnormalities and mosaicisms (all P>0.05). Conclusion:The findings suggested that along with the increase infemale age, there was an increase in the rate of chromosomal abnormalities, at the same time, the type of chromosomal abnormality changed, mainly with an increased incidence of chromosomal aneuploidy, and the proportion of embryos involving multiple chromosomal abnormalities increases significantly.

Objective To explore the relationship between PANoptosis and hepatic ischemia-reperfusion injury (HIRI), and to screen the key genes of PANoptosis in HIRI. Methods PANoptosis-related differentially expressed genes (PDG) were obtained through the Gene Expression Omnibus database and GeneCards database. Gene ontology (GO), Kyoto Encyclopedia of Genes and Genomes (KEGG), and Gene Set Enrichment Analysis (GSEA) were used to explore the biological pathways related to PDG. A protein-protein interaction network was constructed. Key genes were selected, and their diagnostic value was assessed and validated in the HIRI mice. Immune cell infiltration analysis was performed based on the cell-type identification by estimating relative subsets of RNA transcripts. Results A total of 16 PDG were identified. GO analysis showed that PDG were closely related to cellular metabolism. KEGG analysis indicated that PDG were mainly enriched in cellular death pathways such as apoptosis and immune-related signaling pathways such as the tumor necrosis factor signaling pathway. GSEA results showed that key genes were mainly enriched in immune-related signaling pathways such as the mitogen-activated protein kinase (MAPK) signaling pathway. Two key genes, DFFB and TNFSF10, were identified with high accuracy in diagnosing HIRI, with areas under the curve of 0.964 and 1.000, respectively. Immune infiltration analysis showed that the control group had more infiltration of resting natural killer cells, M2 macrophages, etc., while the HIRI group had more infiltration of M0 macrophages, neutrophils, and naive B cells. Real-time quantitative polymerase chain reaction results showed that compared with the Sham group, the relative expression of DFFB messenger RNA in liver tissue of HIRI group mice increased, and the relative expression of TNFSF10 messenger RNA decreased. Cibersort analysis showed that the infiltration abundance of naive B cells was positively correlated with DFFB expression (r=0.70, P=0.035), and the infiltration abundance of M2 macrophages was positively correlated with TNFSF10 expression (r=0.68, P=0.045). Conclusions PANoptosis-related genes DFFB and TNFSF10 may be potential biomarkers and therapeutic targets for HIRI.

Objective:To establish a set of artificial intelligence (AI) verification rules for blood routine analysis.Methods:Blood routine analysis data of 18 474 hospitalized patients from the First Hospital of Jilin University during August 1st to 31st, 2019, were collected as training group for establishment of the AI verification rules,and the corresponding patient age, microscopic examination results, and clinical diagnosis information were collected. 92 laboratory parameters, including blood analysis report parameters, research parameters and alarm information, were used as candidate conditions for AI audit rules; manual verification combining microscopy was considered as standard, marked whether it was passed or blocked. Using decision tree algorithm, AI audit rules are initially established through high-intensity, multi-round and five-fold cross-validation and AI verification rules were optimized by setting important mandatory cases. The performance of AI verification rules was evaluated by comparing the false negative rate, precision rate, recall rate, F1 score, and pass rate with that of the current autoverification rules using Chi-square test. Another cohort of blood routine analysis data of 12 475 hospitalized patients in the First Hospital of Jilin University during November 1sr to 31st, 2023, were collected as validation group for validation of AI verification rules, which underwent simulated verification via the preliminary AI rules, thus performance of AI rules were analyzed by the above indicators. Results:AI verification rules consist of 15 rules and 17 parameters and do distinguish numeric and morphological abnormalities. Compared with auto-verification rules, the true positive rate, the false positive rate, the true negative rate, the false negative rate, the pass rate, the accuracy, the precision rate, the recall rate and F1 score of AI rules in training group were 22.7%, 1.6%, 74.5%, 1.3%, 75.7%, 97.2%, 93.5%, 94.7%, 94.1, respectively.All of them were better than auto-verification rules, and the difference was statistically significant ( P<0.001), and with no important case missed. In validation group, the true positive rate, the false positive rate, the true negative rate, the false negative rate, the pass rate, the accuracy, the precision rate, the recall rate and F1 score were 19.2%, 8.2%, 70.1%, 2.5%, 72.6%, 89.2%, 70.0%, 88.3%, 78.1, respectively, Compared with the auto-verification rules, The false negative rate was lower, the false positive rate and the recall rate were slightly higher, and the difference was statistically significant ( P<0.001). Conclusion:A set of the AI verification rules are established and verified by using decision tree algorithm of machine learning, which can identify, intercept and prompt abnormal results stably, and is moresimple, highly efficient and more accurate in the report of blood analysis test results compared with auto-vefication.

Objective To analyze the impact of patients ages on propofol dosage in painless gastroscopy.Methods A retrospective analysis was conducted on the clinical data of 158 painless gastroscopy patients from January 2017 to June 2020.They were divided into the young group(18～44 years old,n = 57),the middle-aged group(45～59 years old,n = 51),and the elderly group(≥60 years old,n = 50)based on their age.The anesthesia status and safety of each group were compared.Results The results showed that the dosage of propofol,average total dosage of propofol,MAP,HR,RR,SpO2 levels in the young group were higher than those in the middle-aged and elderly groups when consciousness disappeared,and the middle-aged group was higher than the elderly group;The onset time,anesthesia recovery time,orientation recovery time,and departure time in the young group of patients were shorter than those in the middle-aged and elderly groups,and the middle-aged group was shorter than the elderly group(P<0.05).The incidence of airway obstruction,hypoxemia,mandible support,mask ventilation,adverse cardiovascular events,sedation related adverse events,and incidence of obstructed endoscopy in the elderly group were higher than those in the young and middle-aged groups.The incidence of smooth endoscopy was lower than that in the young and middle-aged groups(P<0.05).Conclusion Aging may increase the dosage of propofol in patients underwent painless gastroscopy under anesthesia,prolong the onset time,anesthesia recovery time,orientation recovery time,and departure time,increase stress reactions and adverse reactions,and strengthen monitoring for elderly patients in clinical practice.

Background Civil aviation pilots are actual operators of civil aircraft. Their job operations are directly associated with passenger safety and flight safety. Unsafe aviation operations are related to fatigue caused by poor sleep quality. Recently, with the promotion of China's air transportation business, irregular working hours of civil aviation pilots rise gradually. However, there is still a lack of relevant research on the influence of working conditions on sleep quality in this group. Objective To explore potential impact factors of sleep quality among civil aviation pilots, for the purposes of improving sleep quality and health level of this group and ensuring aviation flight safety by formulating health management suggestions in a targeted manner. Methods All pilots of an aviation company were approached when they visited the Shanghai Hospital of Civil Aviation Administration of China for their health examinations. After informed consent, an online questionnaire survey was conducted. Self-made questionnaires were used to collect information on general conditions, lifestyle, and subjective work stress levels. The Pittsburgh Sleep Quality Index (PSQI) was used to assess sleep quality. A total of 1204 valid questionnaires were recovered. Statistical analysis was conducted using SPSS 26.0 software. Results There were 410 pilots (16.8%) who reported sleep disorders, including insufficient sleep time, difficulty falling asleep, and poor sleep quality, and 894 pilots (74.3%) who reported moderate to severe work stress. Associations were identified between sleep quality of pilots and work stress or lifestyle indicators (P<0.05), while work stress showed the strongest association (r=0.28). Further multiple-factor analysis results showed that severe work stress (OR=4.25, 95%CI: 2.89, 6.30) and alcohol use (OR=1.72, 95%CI: 1.31, 2.27) associated with an increased risk of sleep disorders. Regular breakfast (OR=0.62, 95%CI: 0.42, 0.91) and physical exercise (OR=0.68, 95%CI: 0.45, 1.03) associated with a lower risk of sleep disorders. Conclusion A certain degree of sleep disturbance is reported in the civil aviation pilot group, which is closely related to work stress and lifestyle indicators. Targeted measures must be taken to effectively improve the quality of their sleep.
