Objective:To investigate the effect of Satya mode intervention on self-efficacy,quality of life,mental health and coping style in patients with chronic heart failure.Methods:This randomized controlled study enrolled 136 patients with chronic heart failure admitted in the Second Affiliated Hospital of Xi'an Jiaotong University School of Medicine between December 2022 and May 2023.Patients were randomly divided into control group(n=68,routine psychological intervention)and intervention group(n=68,additional Satya mode intervention).After 6-week intervention,self-efficacy[chronic disease self-efficacy scale(CDSES),general self-efficacy scale(GSES)scores],quality of life[Minnesota living with heart failure questionnaire(MLHFQ)score],mental health[self-rating anxiety scale(SAS),Connor-Davidson resilience scale(CD-RISC)scores]and coping style[simpli-fied coping style questionnaire(SCSQ)score]were compared between the two groups.Results:Compared to pa-tients in the control group after intervention,those in the intervention group had significantly higher scores of CD-SES[(44.67±3.03)points vs.(41.56±2.96)points],GSES[(26.91±1.45)points vs.(23.11±1.39)points],CD-RISC[(73.48±3.61)points vs.(56.45±4.12)points]and SCSQ-positive[(12.39±1.20)points vs.(11.02±0.83)points](P＜0.001 all),and significantly lower scores of MLHFQ[(43.52±3.44)points vs.(48.77±3.76)points],SAS[(31.03±2.46)points vs.(47.86±3.23)points]and SCSQ-negative[(8.35±1.18)points vs.(10.42±1.23)points](P＜0.001 all).Conclusion:Satya model intervention may improve self-efficacy,quality of life,mental health and coping style in patients with chronic heart failure.

Objective:To explore the effects of medication interval on the quality of split-dose bowel preparation and analyze the independent risk factors affecting the quality of bowel preparation.Methods:This pilot study involved two centers. Adult outpatients who underwent screening, surveillance, and diagnostic colonoscopy in the First Affiliated Hospital of Naval Medical University ( n=46) and the Fifth Hospital of Zhangjiakou ( n=20) between April and June 2023 were enrolled. Bowel preparation was conducted based on the guideline. Patients were divided into the short-interval group (4-<10 hours, n=45) and the long-interval group (10-16 hours, n=21) based on the time between the two administrations of polyethylene glycol during bowel preparation. Differences in terms of patient-reported outcome measurements (patient-reported willingness to repeat the bowel preparation regimen, satisfaction with bowel preparation, satisfaction with sleep), defecation frequency, Boston bowel preparation scale scores, bowel preparation bubble scores, bowel preparation qualified rates, polyp detection rates and incidence of adverse events were compared. Relevant factors influencing bowel preparation quality were analyzed by univariate logistic regression. Results:There were no significant differences in patient-reported willingness to repeat the bowel preparation regimen [88.9% (40/45) VS 85.7% (18/21), χ2<0.001, P>0.999], the satisfaction with bowel preparation [65.9% (29/45) VS 57.1% (12/21), χ2=0.469, P=0.493], or the satisfaction with sleep quality [35.6% (16/45) VS 28.6% (6/21), χ2=0.314, P=0.575] between the short-interval and long-interval groups. Similarly, no significant differences were observed between the groups in defecation frequency (11.3±4.8 VS 10.2±4.4, t=0.861, P=0.395), Boston bowel preparation scale scores (8.2±1.4 scores VS 7.9±1.2 scores, t=1.024, P=0.311), bowel preparation bubble scores (8.6±1.0 scores VS 8.4±1.5 scores, t=0.672, P=0.506), bowel preparation qualified rates [88.9% (40/45) VS 90.5% (19/21), χ2<0.001, P>0.999], polyp detection rates [33.3% (15/45) VS 47.6% (10/21), χ2=1.242, P=0.265], or incidence of adverse events [24.4% (11/45) VS 14.3% (3/21), χ2=0.381, P=0.537]. Univariate logistic analysis suggested that a low-fiber diet ( OR=8.100, 95% CI:1.400-46.849, P=0.019) was an influencing factor for qualified bowel preparation. Conclusion:Medication interval of the two doses of polyethylene glycol in a split-dose bowel preparation regimen for colonoscopy has no significant impact on bowel preparation quality. Notably, preoperative low-fiber diet emerges as an independent protective factor for qualified bowel preparation.

Objective:To analyze the effect of high serum ferritin(SF)before transplantation on erythrocyte,granulocyte and platelet implantation in unrelated cord blood transplantation(UCBT)patients with myelodysplastic syndrome(MDS)and acute myeloid leukemia(AML).Methods:The medical records of 60 patients with MDS and AML who underwent UCBT in the First Affiliated Hospital of University of Science and Technology of China from January 2020 to December 2022 were retrospectively collected.According to the SF level before transplantation,they were divided into high SF group(SF ≥ 1 000 μg/L,n=20)and non-high SF group(SF＜1 000 μg/L,n=40).The red blood cell(RBC)infusion volume before transplantation,implantation time of RBC,granulocyte and platelet,implantation risk and prognosis were analyzed and compared between the two groups.Results:There was no correlation between the level of SF before transplantation and RBC infusion.After transplantation,the median implantation time of RBC in the high SF group was 28.5(14-149)d,which was longer than 21(10-83)d in the non-high SF group(P＜0.05).The median time of granulocyte engraftment in the high SF group was 16.5(12-63)d,while that in the non-high SF group was 16(12-49)d,with no statistical difference between the two groups(P＞0.05).The median platelet engraftment time in the high SF group was 45(12-206)d,while that in the non-high SF group was 35.5(14-149)d,with no statistical difference between the two groups(P＞0.05).Kaplan-Meier cumulative implantation probability analysis showed that the rate of erythroid implantation in the non-high SF group was higher than that in the high SF group(P＜0.05),while there was no significant difference in the rates of granulocyte and platelet implantation between the two groups(P＞0.05).The 1-year overall survival rates of the non-high SF group and high SF group were 95％and 90％,respectively,with no statistical difference between the two groups(P＞0.05).Conclusion:SF levels before cord blood transplantation in MDS and AML patients have an impact on post transplant erythroid implantation.Detecting and intervening of iron load in patients before transplant may be beneficial for improving implantation and prognosis.

OBJECTIVE: To explore the immunological mechanisms underlying spermatogenetic malfunction in patients with non-obstructive azoospermia (NOA) based on bioinformatics and machine learning, and to screen out the key genes associated with spermatogenesis failure. METHODS: NOA-related datasets were obtained from the GEO database, and the differentially expressed genes identified by differential analysis and weighted gene co-expression network analysis (WGCNA). A model of spermatogenesis scoring was established for analysis of the immunological microenvironment and cell interaction networks related to spermatogenesis failure. The key genes were screened out by machine learning, followed by analysis of their correlation with T cells and macrophages. An NOA mouse model was constructed for validation of transcriptome sequencing. RESULTS: Seventy-five differentially expressed genes were identified for the establishment of the spermatogenesis scoring model. The low spermatogenesis score group showed a higher infiltration of the immune cells, with an increased proportion of T cells and macrophages and a correlation of cell interaction signals with immunity. SOX30, KCTD19, ASRGL1 and DRC7 were identified by machine learning as the key genes related to spermatogenesis, with down-regulated expressions in the NOA group, and their expression levels negatively correlated with the infiltration of T cells and macrophages. The accuracy of the spermatogenesis scoring and machine learning models, as well as the trend of the expression levels of the key genes, was successfully validated with the transcriptome sequencing data on the NOA mouse testis. CONCLUSION The development of NOA is closely associated with enhanced immunological microenvironment in the testis. T cells and macrophages may play important roles in spermatogenesis failure. SOX30, KCTD19, ASRGL1 and DRC7 are potential biomarkers for the diagnosis and treatment of NOA.

Background::Risk assessment and treatment stratification for three-vessel coronary disease (TVD) remain challenging. This study aimed to investigate the prognostic value of left atrial volume index (LAVI) with the Synergy Between Percutaneous Coronary Intervention with Taxus and Cardiac Surgery (SYNTAX) score II, and its association with the long-term prognosis after three strategies (percutaneous coronary intervention [PCI], coronary artery bypass grafting [CABG], and medical therapy [MT]) in patients with TVD.Methods::This study was a post hoc analysis of a large, prospective cohort of patients with TVD in China, that aimed to determine the long-term outcomes after PCI, CABG, or optimal MT alone. A total of 8943 patients with TVD were consecutively enrolled between 2004 and 2011 at Fuwai Hospital. A total of 7818 patients with available baseline LAVI data were included in the study. Baseline, procedural, and follow-up data were collected. The primary endpoint was major adverse cardiac and cerebrovascular events (MACCE), which was a composite of all-cause death, myocardial infarction (MI), and stroke. Secondary endpoints included all-cause death, cardiac death, MI, revascularization, and stroke. Long-term outcomes were evaluated among LAVI quartile groups. Results::During a median follow-up of 6.6 years, a higher LAVI was strongly associated with increased risk of MACCE (Q3: hazard ratio [HR] 1.20, 95% confidence interval [CI] 1.06-1.37, P = 0.005; Q4: HR 1.85, 95%CI 1.64-2.09, P <0.001), all-cause death (Q3: HR 1.41, 95% CI 1.17-1.69, P <0.001; Q4: HR 2.54, 95%CI 2.16-3.00, P <0.001), and cardiac death (Q3: HR 1.81, 95% CI 1.39-2.37, P <0.001; Q4: HR 3.47, 95%CI 2.71-4.43, P <0.001). Moreover, LAVI significantly improved discrimination and reclassification of the SYNTAX score II. Notably, there was a significant interaction between LAVI quartiles and treatment strategies for MACCE. CABG was associated with lower risk of MACCE than MT alone, regardless of LAVI quartiles. Among patients in the fourth quartile, PCI was associated with significantly increased risk of cardiac death compared with CABG (HR: 5.25, 95% CI: 1.97-14.03, P = 0.001). Conclusions::LAVI is a potential index for risk stratification and therapeutic decision-making in patients with three-vessel coronary disease. CABG is associated with improved long-term outcomes compared with MT alone, regardless of LAVI quartiles. When LAVI is severely elevated, PCI is associated with higher risk of cardiac death than CABG.

Objective To investigate the incidence rate,clinical characteristics,and prognosis of neonatal stroke in Shenzhen,China.Methods Led by Shenzhen Children's Hospital,the Shenzhen Neonatal Data Collaboration Network organized 21 institutions to collect 36 cases of neonatal stroke from January 2020 to December 2022.The incidence,clinical characteristics,treatment,and prognosis of neonatal stroke in Shenzhen were analyzed.Results The incidence rate of neonatal stroke in 21 hospitals from 2020 to 2022 was 1/15 137,1/6 060,and 1/7 704,respectively.Ischemic stroke accounted for 75％(27/36);boys accounted for 64％(23/36).Among the 36 neonates,31(86％)had disease onset within 3 days after birth,and 19(53％)had convulsion as the initial presentation.Cerebral MRI showed that 22 neonates(61％)had left cerebral infarction and 13(36％)had basal ganglia infarction.Magnetic resonance angiography was performed for 12 neonates,among whom 9(75％)had involvement of the middle cerebral artery.Electroencephalography was performed for 29 neonates,with sharp waves in 21 neonates(72％)and seizures in 10 neonates(34％).Symptomatic/supportive treatment varied across different hospitals.Neonatal Behavioral Neurological Assessment was performed for 12 neonates(33％,12/36),with a mean score of(32±4)points.The prognosis of 27 neonates was followed up to around 12 months of age,with 44％(12/27)of the neonates having a good prognosis.Conclusions Ischemic stroke is the main type of neonatal stroke,often with convulsions as the initial presentation,involvement of the middle cerebral artery,sharp waves on electroencephalography,and a relatively low neurodevelopment score.Symptomatic/supportive treatment is the main treatment method,and some neonates tend to have a poor prognosis.

This study analyzed the epidemic characteristics and spatial and temporal clustering of leptospirosis in Wenzhou from 2014 to 2023,to provide a scientific basis for prevention and control.Data for leptospirosis cases reported in Wenzhou from 2014 to 2023 were collected.Descriptive epidemiological approaches were used to analyze the cases'prevalence character-istics.Spatial autocorrelation analysis was performed in ArcGIS 10.2 software,and spatiotemporal clusters were scanned with SaTScan 10.1 software.From 2014 to 2023,189 leptospirosis cases were reported in Wenzhou,and the average annual inci-dence rate was 0.23/100 000.Relatively fewer cases occurred in 2014-2018,whereas significantly more cases occurred after 2019,and the largest number of reported cases was reported in 2021(62 cases).The peak incidence was from August to Octo-ber,accounting for 88.36％of the total incidence.The cases were mainly in males,and the sex ratio was 5.30∶1 male:female.Moreover,the cases were mainly in people in their 60s,accounting for 59.26％of total cases,and in people who were farmers,accounting for 72.49％of total cases.Global spatial autocorrelation analysis indicated that cases were randomly distributed from 2014 to 2018,and the incidence showed spatial clustering from 2019 to 2023(Moran's I＞0,P＜0.05).Local spatial autocor-relation and spatiotemporal scanning analysis revealed that leptospirosis cases were concentrated primarily in northern hilly areas of Yongjia County and other inland areas rich in vegetation from 2019 to 2023.In the past 5 years,the number of lepto-spirosis cases in Wenzhou increased,and the incidence of leptospirosis showed clear seasonal and spatial clustering.Cases were mainly in middle-aged and older farmers.Recommendations in-clude expanding the monitoring scope of leptospirosis,and per-forming prevention and control measures such as health education for key groups in key areas before the high-incidence season.
