Objective To explore the causal relationship between immune cells and heart failure (HF), and the mediating role of serum metabolites, in order to identify potential biomarkers and therapeutic targets. Methods We employed a two-sample Mendelian randomization (MR) analysis method based on genome-wide association study (GWAS) data, analyzing the direct and indirect effects of 731 types of immune cells and 1 400 metabolites on HF. We selected valid instrumental variables and conducted statistical analyses using R software. The primary analysis was performed using the inverse variance weighted method, supplemented by MR-Egger analysis and weighted median method. The stability of the results was assessed through tests such as Cochran’s Q test. Results Our research found a negative causal relationship between PD-L1 on CD14−CD16+ and HF. Sensitivity analysis supported this result. The reverse MR analysis did not find an effect of HF on PD-L1 on CD14−CD16+, indicating that PD-L1 on CD14−CD16+ might play a unidirectional role in reducing the risk of HF. Further mediation MR analysis showed that PD-L1 on CD14−CD16+ might influence the risk of HF onset by regulating the levels of sphingomyelin (d17:1/14:0, d16:1/15:0), with a mediation effect ratio of 6.7%. Conclusion PD-L1 on CD14−CD16+ may reduce the risk of HF by elevating the levels of sphingomyelin (d17:1/14:0, d16:1/15:0), which provides a new perspective for understanding the pathogenesis of HF.

Objective To analyze the correlation between the poor position of pedicle screw after lumbar internal fixation and the occurrence of postoperative neurological symptoms.Methods The clinical data of patients who underwent lumbar pedicle screw surgery in our hospital from January 2017 to December 2023 were analyzed retrospectively.Record the patient's sex,age,diagnosis,surgical segment,the presence of postoperative neurological complications,the types of neurological complications.According to the postoperative CT,the screw penetration zone and grade were evaluated,and the distribution of different pedicle screw penetration types was recorded.The correlation between different types of pedicle screw penetration and postoperative neurological symptoms was analyzed.Results A total of 184 patients were included,including 80 males and 104 females.Age ranged from 18 to 82 years,with an average of 60.1±14.2 years.35 patients developed new neurological symptoms after operation.The incidence of postoperative neurological symptoms caused by pedicle medial quadrant screw penetration and lower quadrant screw penetration was higher than that of pedicle superior quadrant and lateral quadrant screw penetration.From L1 to L5,the risk of postoperative neurological symptoms caused by screw penetration in the medial quadrant of the pedicle increases gradually.When the penetration distance of pedicle medial quadrant screws in L4 and L5 segments is≥2mm,the risk of postoperative neurological symptoms is high.When the penetration distance of pedicle medial quadrant screws in L1,L2 and L3 segments is greater than 4mm,the risk of postoperative neurological symptoms is high.The distance of pedicle screw penetrating the medial quadrant of pedicle was positively correlated with the incidence of postoperative neurological symptoms(P<0.05).Conclusion The lateral and superior quadrants of the pedicle may be regarded as safety zones for lumbar pedicle screw placement.For the L1～L3 segments,screw penetration depth should not exceed 4 mm;whereas for the L4～L5 segments,the safety threshold must be strictly controlled within 2 mm.

Objective To investigate the causal relationship between psychiatric and psychological disorders(depression,bipolar dis-order,and schizophrenia)and non-alcoholic fatty liver disease(NAFLD).Methods The two-sample Mendelian randomization(MR)method was adopted,with depression,bipolar disorder,and schizophrenia as exposure variables and NAFLD as the outcome variable.The single nucleotide polymorphisms(SNPs)independently associated with exposure variables were obtained from the summary data of the genome-wide association study(GWAS)as instrumental variables for MR analysis.The analysis results of the inverse-variance weighted(IVW)were used as the primary outcome indicators,while those of the MR Egger regression method,weighted median,and weighted mode as supplementary results.The Cochran's Q test,MR-Egger intercept,and"leave-one-out"method were used for sensi-tivity analysis.Results The results of IVW analysis showed that depression was positively correlated with the incidence risk of NAFLD(OR=1.21,95％CI:1.01-1.44,P＜0.05),while bipolar disorder was negatively correlated with the incidence risk of NAFLD(OR=0.91,95％CI:0.84-1.00,P＜0.05).No causal relationship was found between schizophrenia and NAFLD.The heterogeneity and sen-sitivity analysis supported the robustness of the results of the study.Conclusion Depression and bipolar disorder are causally associat-ed with the incidence of NAFLD.Depression is associated with an increased risk of NAFLD,while bipolar disorder is associated with a reduced risk of NAFLD.

Objective:To investigate the current status of preimplantation genetic testing for aneuploidies (PGT-A) in China in 2024 and to provide recommendations for ensuring the consistency of PGT-A results.Methods:This study was a nationwide external quality assessment research. The National Center for Clinical Laboratories of the National Health Commission conducted two surveys in June and December 2024, with participation from 31 laboratories across China. During each survey, quality control samples of varying concentrations were distributed: the first survey distributed 6 samples (Batch Nos. 202401-202406) and the second survey distributed 3 samples (Batch Nos. 202431-202433). Participating laboratories were required to submit information including detection platforms, single-cell amplification methods, library construction methods, sequencing instruments, and test results. Collected data were statistically analyzed using Microsoft Excel to evaluate laboratories' PGT-A testing capabilities and determine whether results met predefined quality control requirements.Results:All 31 laboratories submitted results for both surveys. In the first survey, 90.3% (28/31) met qualification criteria with a 9.7% failure rate (3/31). For individual batches, pass rates were 90.3% (28/31) for batches 202401-202403 and 100% (31/31) for batches 202404-202406. The second survey achieved 100% (31/31) compliance across all three batches (202431-202433), with each batch maintaining a 100% pass rate.Conclusion:The detection quality of PGT-A in China is generally good, but with differences, and factors such as sample concentration, transportation conditions and detection methods affect the consistency of the results. The study highlights the urgent need for nationwide external quality assessment of PGT-A in China. This will help identify issues in laboratories in a timely manner and ensure the consistency of PGT-A test results.

Objective:To explore the implementation method of the "daily-monthly-quarterly" quality control model based on total quality management (TQM) theory in nursing quality management, and evaluate its application effectiveness.Methods:A quasi-experimental research method was used. The quarterly quality control model employed at Shanxi Medical University Second Hospital from 2018 to 2019 was set as the control group, and the"day-month-quarter" quality control model based on TQM implemented from 2020 to 2022 was set as the observation group. The nurse practice environment assessment scores from 2018 to 2022 were analyzed; the nursing quality-sensitive indicators between the two groups were compared, including the incidence rate of overall adverse event, falls among hospitalized patients, pressure ulcers of stage 2 and above, unplanned extubations, and catheter-related infections (central venous catheter-related bloodstream infections, ventilator-associated pneumonia, and catheter-associated urinary tract infections).Results:The nurse practice environment assessment scores from 2018 to 2022 were (69.11 ± 19.66), (75.20 ± 18.70), (77.60 ± 17.65), (82.45 ± 16.44), and (88.00 ± 15.06). The differences compared to the previous year were statistically significant ( t=3.63-9.24, all P<0.05).After the intervention, the incidence rates of overall adverse events, falls among hospitalized patients, unplanned extubation, central venous catheter-related bloodstream infections, and ventilator-associated pneumonia in the control group were 0.385% (499/129 678), 0.072% (94/129 678), 0.051% (66/129 678), 0.037% (23/62 390), and 0.746% (43/5 761). Compared to 0.258% (551/213 851), 0.048% (103/213 851), 0.033% (71/213 851), 0.019% (19/98 642), and 0.444% (88/19 826) in the observation group. The differences were statistically significant ( χ2values were 3.89-42.83, all P<0.05). There were no statistically significant differences in the incidence rates of pressure ulcers of stage 2 and above and catheter-associated urinary tract infections (both P>0.05). Conclusions:The "daily-monthly-quarterly" quality control model based on TQM is beneficial in improving nursing quality and ensuring patient safety.
