Objective:To detect the prevalence of mosaic loss of chromosome Y in adult men in ten study areas in China, describe the epidemiological distribution of mosaic loss of chromosome Y (mLOY) carriers and assess its prospective association with lung cancer.Methods:Based on the data from baseline survey, genetic analysis and follow-up (as of December 31, 2018) from China Kadoorie Biobank, we used Mosaic Chromosomal Alterations pipeline to detect mLOY carriers in 10 areas in China and described the epidemiological characteristics of mLOY carriers in adult men, including age, area distribution, lifestyle and disease history. We used multivariate logistic regression model to identify the potential relevant factor of mLOY. Cox proportional hazard regression model was fitted to assess the prospective association of mLOY with lung cancer. Stratification analysis were conducted to evaluate the potential modification effects of smoking and age. We also conducted mediation analysis to assess the mediating effect of mLOY in the association between smoking and lung cancer.Results:A total of 42 859 adult men were included in our analysis, in whom 2 458 mLOY carriers were detected (5.7%). The detection rate increased with age ( P<0.05). The detection rate was higher in urban area (7.3%±0.2%) than that in rural area (4.7%±0.1%). The results of logistic regression analysis indicated that smoking might be a risk factor for the detection of mLOY ( OR=1.49, 95% CI:1.36-1.64). After follow-up for average 11.1 years, 1 041 lung cancer cases were observed. The prospective analysis showed that mLOY carriers had an increased risk for lung cancer by 24% compared with non-mLOY carriers ( HR=1.24, 95% CI:1.01-1.52) and expanded mLOY carriers (mLOY cell proportion ≥10%) had an increased risk for lung cancer by 50% ( HR=1.50, 95% CI:1.13-2.00). Stratification analysis showed no modification effects of smoking and age in the association between mLOY and lung cancer (interaction P>0.05). Mediation analysis showed that mLOY could be a mediating factor in the association between smoking and lung cancer, the estimated effect was 0.09 (0.01-0.17). Conclusions:There were significant differences in the detection rate of mLOY in adult men with different social-economic characteristics and lifestyles in ten areas in China. Besides, mLOY carriers, especially expanded mLOY carriers, had increased risk for lung cancer and mLOY might be a mediating factor in the association between smoking and lung cancer.

Objective:To investigate the application value of 0.9% sodium chloride injection for a balloon catheter in bedside Doppler ultrasound-guided percutaneous dilatational tracheostomy in critically ill patients.Methods:A randomized controlled study was conducted involving 54 critically ill patients who were scheduled for tracheostomy at the Intensive Care Medicine, Jilin Province People's Hospital, from September 2022 to April 2024. These patients were randomly divided into a conventional group ( n = 27) and an ultrasound group ( n = 27) using the random number table method. The conventional group underwent empirical extubation, while the ultrasound group received extubation guided by a balloon catheter filled with 0.9% sodium chloride injection under ultrasound guidance. The following parameters were observed in both groups: duration of operation, incidence of blood oxygen saturation < 90%, incidence of puncturing the endotracheal tube or balloon catheter, distance from extubation site to the incisors, dosage of propofol, length of incision, and amount of bleeding. Results:Both groups of patients successfully completed the procedure on the first attempt, with no significant complications such as extensive bleeding, vascular injury, thyroid damage, or pneumothorax. In the ultrasound group, the incidence of puncturing the endotracheal tube or balloon catheter, duration of operation, and dosage of propofol were 3.7% (1/27), (6.2 ± 1.4) minutes, and 40 (40, 40) mg, respectively, all of which were superior to those in the conventional group [48.1% (13/27), (9.8 ± 2.7) minutes, 80 (70, 80) mg, χ2 = 23.19, t = 6.11, Z = -6.29, all P < 0.05]. The incidence of hypoxemia in the ultrasound group was 0, which was significantly lower than that in the conventional group [29.6% (8/27), P < 0.05]. The distance from extubation site to the incisors in the ultrasound group was 18 (17, 18) cm, which was significantly different from 18 cm of the conventional group ( Z = -2.62, P < 0.05). There were no statistically significant differences in length of incision and amount of bleeding between the two groups ( P = 0.652, 0.878). Conclusion:Performing PDT under bedside Doppler ultrasound guidance with a 0.9% sodium chloride injection-filled balloon catheter in patients requiring mechanical ventilation can reduce procedure duration, lower the incidence of hypoxemia and puncturing of the endotracheal tube or balloon catheter, decrease the use of sedative medications, and enhance the accuracy and safety of the procedure.

Objective To evaluate the efficacy of Schroth PSSE combined with 3D printing braces in the treatment of adolescent idiopathic scoliosis.Method Forty patients were included and divided into a support group(3D printing support group)and a support+exercise therapy group(3D printing support+Schroth PSSE group).Excluding outliers and lost follow-up data,32 patients were ultimately included,with 16 patients in each group.Wearing time≥18 h for both groups of 3D printing supports.The intervention period of Schroth PSSE is 12 weeks,and exercise is maintained after 12 weeks until the end of follow-up.The longest follow-up time for the brace group was 25 months,with an average follow-up time of(15.00±1.29)months.The longest follow-up time for the brace+exercise therapy group was 24 months,with an average follow-up time of(16.59±1.01)months.Relevant indicators were evaluated after follow-up.Results The support and exercise therapy group showed better improvement in Cobb angle and trunk rotation angle(ATR)than the support group,with statistically significant differences(P<0.05);The distance between the midpoint of the C7 vertebral body and the midline of the sacrum(C7-CSVL)in the support and exercise therapy group showed a statistically significant difference before and after treatment(P<0.05),while there was a significant difference before and after Apical Vertebral Translation(AVT)treatment(P<0.01).There was no statistically significant difference compared to the support group(P<0.05);In terms of SRS-22 score,the brace+exercise therapy group can comprehensively improve the SRS-22 score.Conclusion The combination of Schroth PSSE and 3D printing braces has a better effect on improving Cobb angle and torso rotation angle,improving coronary imbalance,increasing patient satisfaction,and improving quality of life compared to using 3D printing braces alone.

Objective:To analyze the duration of the second stage of labor without epidural anesthesia and its association with pregnancy outcome.Methods:This retrospective study involved 12 789 women who delivered without epidural anesthesia in the First Affiliated Hospital of Kunming Medical University from January 1, 2014 to December 31, 2017. These subjects were divided into primipara group (9 517 cases) and multipara group (3 272 cases). Demographic characteristics, maternal and neonatal outcomes and the duration of the second stage of labor were compared between the two groups using two independent samples t-test, Mann-Whitney U test and Chi-square test (Fisher's exact test). Differences in the maternal and neonatal outcomes were also analyzed among different subgroups in primiparae [length of second stage: <1 h group ( n=6 265), ≥1-2 h group ( n=2 305), ≥2-3 h group ( n=831) and ≥3 h group ( n=116)] and multiparae [length of second stage <1 h group ( n=3 144), ≥1-2 h group ( n=102) and ≥2 h group ( n=26)]. The association between second stage length and pregnancy outcomes was analyzed with Cramer's V. After adjusted for maternal age, gestational weeks at delivery, body mass index before pregnancy, complications during pregnancy and neonatal birth weight, the relationship between the duration of the second stage and adverse outcomes was analyzed by binary logistic regression analysis. Results:The 95 th percentile of the second-stage labor duration was 143 min for primiparae and 52 min for multiparae. The rates of vaginal delivery, forceps delivery, cesarean section in the second stage, episiotomy, third- or fourth-degree perineal laceration, postpartum hemorrhage, grade Ⅱ postpartum hemorrhage, transfusion, umbilical arterial blood gas pH<7.15 and transferring to neonatal intensive care unit (NICU) were all correlated with the duration of second stage in primiparae (Cramer's V values: 0.22, 0.23, 0.03, 0.22, 0.05, 0.10, 0.03, 0.03, 0.03 and 0.07, respectively, all P<0.05), and so did those of vaginal delivery, forceps delivery, episiotomy, postpartum hemorrhage, grade Ⅱ postpartum hemorrhage, transfusion and transferring to NICU in multiparae (Cramer's V values: 0.18, 0.19, 0.28, 0.14, 0.09, 0.13 and 0.06, respectively, all P<0.05). Logistic analysis showed that in primiparae, the duration of second stage >1 h was an independent risk factor for episiotomy, third- or fourth-degree perineum laceration, forceps delivery, postpartum hemorrhage, admission to NICU and umbilical arterial blood gas pH<7.15 [adjusted OR (95% CI): 2.080 (1.907-2.268), 1.773 (1.080-2.911), 1.625 (1.420-1.859), 1.365 (1.231- 1.514), 1.305 (1.165-1.462) and 1.246 (1.081-1.436), respectively], while second stage length >2 h was the independent risk factor for episiotomy, forceps delivery, third- or fourth-degree perineum laceration, postpartum hemorrhage, grade Ⅱ postpartum hemorrhage, blood transfusion, admission to NICU and umbilical arterial blood gas pH<7.15 [adjusted OR (95% CI): 4.844 (4.132-5.678), 4.223 (3.571-4.993), 3.289 (1.806-5.989), 1.952 (1.675-2.274), 1.781 (1.057-3.001), 1.654 (1.025-2.668), 1.682 (1.421-1.991) and 1.298 (1.039-1.620), respectively]. In multiparae, the length of second stage >1 h was an independent risk factor for episiotomy, blood transfusion, forceps delivery, postpartum hemorrhage and admission to NICU [adjusted OR (95% CI): 8.796 (5.717-13.534), 7.469 (2.874-19.411), 6.135 (3.217-11.699), 2.697 (1.624-4.477) and 1.814 (1.063-3.097), respectively], while the duration of second stage >2 h was the independent risk factor for episiotomy, third- or fourth-degree perineum laceration, blood transfusion, grade Ⅱ postpartum hemorrhage, forceps delivery and postpartum hemorrhage [adjusted OR (95% CI): 38.868 (14.948-101.063), 28.046 (2.780-282.490), 20.076 (5.384-74.866), 16.327 (3.406-78.274), 14.337 (5.351-38.411) and 9.036 (3.880-21.011), respectively]. Conclusions:The duration of the second stage of labor without epidural anesthesia is between that reported by Friedman and by Zhang. A prolonged second stage of labor may increase the risk of adverse pregnancy outcomes.

Ferroptosis is a new form of regulated cell death discovered in recent years, which is iron-dependent cell death characterized by peroxidation of polyunsaturated fatty acid phospholipids. Recent studies have shown that radiotherapy can induce ferroptosis in cancer cells via ionizing radiation. Targeting ferroptosis plays a synergistic role in tumor suppression with radiation, which not only further deepens the connotation of radiobiology, but also provides a new perspective for tumor radiosensitization. This review systematically summarizes the occurrence and defense of ferroptosis, focusing on the key role of ferroptosis in the radiobiological effects of tumor cells and the potential application of ferroptosis in radiosensitization.

Objective:To investigate the association between CITP/MMP-1 ratio and the severity of Myocardial fibrosis (MF) in patients with Chronic Heart failure (CHF) and its diagnostic and prognostic value in patients with MF.Methods:A retrospective study was conducted to select 110 cases [86 males, (56.60±11.15) years old;24 females, (60.06±12.02) years old] who were hospitalized in the Department of Cardiology, Teda International Cardiovascular Hospital from May 18, 2021 to February 30, 2022 and underwent magnetic magnetic examination. Serum CITP and MMP-1 were detected by enzyme-linked immunoassay and CITP/MMP-1 ratio was calculated. Plasma brain natriuretic peptide (BNP) was detected by automatic chemiluminescence analyzer. Anova and non-parametric test were used to compare the difference of indexes among all groups. Spearman analysis was used to analyze the correlation between serum collagen metabolites and the severity of myocardial fibrosis. Logistic regression analysis was performed for multivariate analysis, and ROC curve was used to evaluate the auxiliary diagnostic value of related indexes. Major adverse cardiac events within 1 year after discharge were recorded, including cardiogenic death, HF rehospitalization, malignant arrhythmia, and myocardial infarction. The risk factors of poor prognosis were analyzed by Cox regression. Patients were divided by the median value of CITP/MMP-1 ratio or the median value of CITP/MMP-1 ratio and BNP. Survival analysis was performed by Kaplan-Meier and Log Rank test was performed.Results:Serum MMP-1 and BNP in LGE (+) group were higher than those in LGE (-) group (1.79 ng/ml > 0.91 ng/ml, Z=-2.924; 503 pg/ml > 367 pg/ml, Z=-1.932; P<0.05); The CITP/MMP-1 ratio in the LGE (+) group was lower than that in the LGE (-) group (3.84 < 10.85, Z=-3.601, P<0.001). MMP-1 in CHF with arrhythmia group was higher than that in CHF group (1.98 ng/ml > 1.25 ng/ml, Z=-2.016), while CITP/MMP-1 ratio was lower than that in CHF group (3.25 < 5.73, Z=-2.751), all P<0.05. CITP/MMP-1 ratio in CHF patients was negatively correlated with the severity of MF ( r=-0.363, P<0.001), and BNP and MMP-1 were positively correlated with the severity of MF ( r=0.267, r=0.264, P<0.05). Serum BNP was positively correlated with collagen metabolite MMP-1 and negatively correlated with CITP/MMP-1 ratio (all P<0.05). Logistic multivariate regression analysis showed that only CITP/MMP-1 was a predictor of myocardial fibrosis, with an OR value of 0.624 ( P=0.005). ROC curve was used to evaluate serum BNP, MMP-1 and CITP/MMP-1 ratio in the diagnosis of myocardial fibrosis in HF patients, with AUC of 0.653, 0.696 and 0.754, respectively. The accuracy of CITP/MMP-1 ratio in diagnosing fibrosis was better than that of BNP by comparing their AUC, and the difference was statistically significant ( Z=-3.808, P<0.001). Cox regression analysis showed that CITP/MMP-1 ≤3.84 was a risk factor for poor prognosis, OR=2.647 ( P=0.009). Kaplan-Meier survival analysis at 1-year follow-up showed that the survival rate of the group with lower CITP/MMP-1 ratio was significantly lower than that of the group with higher CITP/MMP-1 ratio ( P=0.014). The survival rate of CITP/MMP-1 increased and BNP decreased group was higher than that of CITP/MMP-1 decreased and BNP increased group ( P=0.011). Conclusions:The ratio of CITP/MMP-1 can be used as a negative correlation indicator of the degree of cross-linking, which is better than BNP in the evaluation of MF, and has a good auxiliary diagnostic value for myocardial fibrosis in patients with chronic heart failure, and is expected to become a protective indicator for patients with chronic heart failure and be used in clinical evaluation of myocardial fibrosis. CITP/MMP-1 ratio is associated with the incidence of major adverse cardiac events, and CITP/MMP-1 ≤3.84 can be used as a predictor of prognostic adverse cardiovascular events in CHF patients.

Objective:To explore the effect of training and management based on cognitive conflict on nursing ability and adverse events of nurses in Department of Interventional Therapy.Methods:Using the convenient sampling method, 90 nurses in the Department of Interventional Therapy of three Class Ⅲ Grade A hospitals in Shanxi Province from January to October 2021 and 170 patients with interventional therapy admitted to three Class Ⅲ Grade A hospitals in Shanxi Province from February 2020 to October 2021 were selected as the research object. The patients admitted before the implementation of personnel training and management based on cognitive conflict from February to December 2020 were set as the control group, and the patients admitted after the implementation of personnel training and management based on cognitive conflict from January to October 2021 were set as the research group, with 85 cases each. We compared the theoretical knowledge, nursing skills, clinical strain ability and critical thinking ability of nurses before and after the implementation of personnel training and management based on cognitive conflict, as well as the occurrence of adverse events and nursing satisfaction of patients.Results:Three and six months after the implementation of personnel training and management based on cognitive conflict, the scores of intervention theoretical knowledge, nursing skills, clinical strain ability and critical thinking ability of nurses were higher than those before the implementation, and the scores in six months after the implementation were higher than those in three months after the implementation, with statistically significant differences ( P<0.05) . The total incidence of adverse events in the research group was 11.76% (10/85) , which was lower than 23.53% (20/85) in the control group with a statistical difference ( P<0.05) . The patient satisfaction of the research group was 95.29% (81/85) , which was superior to 85.88% (73/85) of the control group, with a statistically significant difference ( P<0.05) . Conclusions:The implementation of personnel training and management based on cognitive conflict in the Interventional Therapy Department can improve the quality of nursing service of nurses, reduce the risk of adverse events, and increase patient satisfaction, which is worthy of clinical application.

Background: Clinical dexamethasone (DEX) treatment or stress in bovines results in extensive physiological changes with prominent hyperglycemia and neutrophils dysfunction. Objectives: To elucidate the effects of DEX treatment in vivo on cellular energy status and the underlying mechanism in circulating neutrophils. Methods: We selected eight-month-old male bovines and injected DEX for 3 consecutive days (1 time/d). The levels of glucose, total protein (TP), total cholesterol (TC), and the proinflammatory cytokines interleukin (IL)-1β, IL-6 and tumor necrosis factor (TNF)-α in blood were examined, and we then detected glycogen and adenosine triphosphate (ATP) content, phosphofructosekinase-1 (PFK1) and glucose-6-phosphate dehydrogenase (G6PDH) activity, glucose transporter (GLUT)1, GLUT4, sodium/glucose cotransporter (SGLT)1 and citrate synthase (CS) protein expression and autophagy levels in circulating neutrophils. Results: DEX injection markedly increased blood glucose, TP and TC levels, the Ca 2+ /P 5+ ratio and the neutrophil/lymphocyte ratio and significantly decreased blood IL-1β, IL-6 and TNF-α levels. Particularly in neutrophils, DEX injection inhibited p65-NFκB activation and elevated glycogen and ATP contents and SGLT1, GLUT1 and GR expression while inhibiting PFK1 activity, enhancing G6PDH activity and CS expression and lowering cell autophagy levels. Conclusions DEX induced neutrophils glucose uptake by enhancing SGLT1 and GLUT1 expression and the transformation of energy metabolism from glycolysis to pentose phosphate pathway (PPP)-tricarboxylic acid (TCA) cycle. This finding gives us a new perspective on deeper understanding of clinical anti-inflammatory effects of DEX on bovine.
