BackgroundIn Sichuan Province， most healthcare institutions providing mental health services have adopted self-developed evaluation indicators for the quality of nursing care in psychiatric closed wards， lacking unified standards. This results in insufficient authority and homogeneity， which is unfavorable for the standardized assessment and continuous improvement of nursing quality. ObjectiveTo construct a standardized evaluation indicator system for nursing quality of psychiatric closed wards in Sichuan Province， so as to provide references for nursing quality management and assessment. MethodsBased on bio-psycho-social medical model and guided by "Structure-Process-Outcome" quality evaluation framework， preliminary evaluation indicators for nursing quality in psychiatric closed wards were developed through literature analysis， research team discussions and clinical experience. Through two rounds of Delphi expert consultation， the indicators were revised and finalized. ResultsThe response rates for two rounds of Delphi expert consultation questionnaire were 100%. The expert authority coefficients were 0.845 and 0.864， respectively， and the Kendall's coordination coefficients ranged from 0.119 to 0.210 （P<0.01）. Ultimately， a nursing quality evaluation index system for psychiatric closed wards was established， comprising 3 first-level indicators， 9 second-level indicators and 46 third-level indicators. ConclusionThe nursing quality evaluation indicators for psychiatric closed wards constructed based on the Delphi method can provide references for nursing quality management and evaluation in such wards. ［Funded by Research Project Fund of Sichuan Nursing Society （number， H20004）； Sichuan Hospital Association Hospital Management Research Special Fund （number， YG2323）］

BACKGROUND:Hyperhomocysteinemia is closely related to the function of islet β cells,but its specific molecular mechanism is not fully understood. OBJECTIVE:To investigate the role of N6 methyltransferase-like 3(METTL3)in homocysteine(Hcy)-induced autophagy of mouse islet β cells. METHODS:The 3rd and 4th generation mouse islet β cells were taken for the experiment.(1)Cell modeling and grouping:cells in control group were not treated with Hcy,while those in homocysteine group were treated with 100 μmol/L Hcy for 48 hours.(2)The mouse islet β-cells were transfected with the plasmids overexpressing Ad-METTL3 and si-METTL3 according to the instructions of LipofectamineTM 2000.Three different interfering fragments were designed,and the one with the best interfering efficiency was verified and screened by PCR.(3)After transfection,the cells were divided into control group,Hcy group,Ad-NC(negative control)+Hcy group,Ad-METTL3+Hcy group,si-NC(negative control)+Hcy group and si-METTL3+Hcy group.(4)qRT-PCR and western blot were used to detect the expression levels of METTL3 and autophagy-related proteins LC3Ⅱ/Ⅰ and p62 in cells.Insulin level was determined by ELISA to evaluate insulin secretion capacity of islet cells.Autophagy-related proteins and insulin level were detected after overexpression and interference with METTL3. RESULTS AND CONCLUSION:Compared with the control group,the expression level of LC3Ⅱ/Ⅰ was increased(P＜0.05),the expression of p62 was significantly reduced(P＜0.05),and the insulin secretion capacity was significantly decreased(P＜0.05)in the Hcy group.Compared with the control group,the protein and mRNA levels of METTL3 were reduced in the Hcy group(P＜0.05).After METTL3 silencing in islet β cells,Hcy further upregulated the expression of LC3Ⅱ/Ⅰ(P＜0.05),significantly dowregulated the expression of p62(P＜0.05),and increased the insulin level(P＜0.05).After overexpression of METTL3,Hcy significantly decreased the LC3Ⅱ/Ⅰ expression and increased the p62 expression in islet β cells(P＜0.05).To conclude,METTL3 is involved in the Hcy-induced autophagy regulation of islet β cells and plays a role in the regulation of insulin secretion.

Objective:To explore the risk factors for lymphoproliferative disorders (PTLD) in children with thalassemia major (TM) after allogeneic hematopoietic stem cell transplantation (allo-HSCT).Methods:This was a retrospective case-control study.A total of 482 children with TM who underwent allo-HSCT at Shenzhen Children′s Hospital between January 2020 and December 2022 were selected and classified into the PTLD and non-PTLD groups according to the occurrence of PTLD.The risk factors for PTLD after allo-HSCT in children with TM were analyzed, and the diagnostic efficiency of relevant risk factors for PTLD was analyzed by receiver operating characteristic (ROC) curve.Results:A total of 25 out of 482 patients (5.2%, 25/482) developed PTLD about 114 (54-271) days after allo-HSCT.Among them, 12 cases (12/25, 48.0%) occurred within 100 days, and 22 cases (22/25, 88.0%) occurred within 1 year after allo-HSCT.Univariate analysis showed that there were significant differences in gender composition, type of transplant donor, number of natural killer cells and B lymphocytes in peripheral blood at 30 days after allo-HSCT, positive rate of plasma Epstein-Barr virus deoxyribonucleic acid (EBV-DNA) and incidence rate of acute graft-versus-host disease (aGVHD) between the 2 groups (all P<0.05).Multivariate Logistic regression analysis showed that female ( OR=3.196, 95% CI: 1.144-8.929), positive plasma EBV-DNA ( OR=17.523, 95% CI: 5.449-56.344) and aGVHD ( OR=3.156, 95% CI: 1.161-8.575) were independent risk factors for PTLD after allo-HSCT in TM children (all P<0.05).The ROC curve analysis showed that positive plasma EBV-DNA had an excellent accuracy in predicting the occurrence of PTLD after allo-HSCT (sensitivity was 0.796, specificity was 0.800, area under the curve was 0.803).If combined with aGVHD and gender, the area under the curve for the prediction of PTLD increased to 0.831. Conclusions:Female, positive plasma EBV-DNA and aGVHD are independent risk factors for PTLD after allo-HSCT in children with TM.It provides useful early warnings for the prediction and prevention of PTLD.

OBJECTIVE To study the correlation between color and inner quality during the processing of Prunus mume carbon， and provide reference for the determination of processing end point of P. mume carbon. METHODS The chromaticity value of P. mume carbon powder was measured by colorimeter， and the inner quality of P. mume carbon was measured by selecting the contents of water， water-soluble extract， citric acid and tannin. The dynamic change trend of the chromaticity value， water， water- soluble extract， the contents of citric acid and tannin in P. mume carbon under different processing time was analyzed. The correlation between color and the above indexe contents was analyzed， and the regression equation of inner quality-chromaticity value was established. Combined with principal component analysis （PCA）， hierarchical cluster analysis （CA） and partial least squares discriminant analysis （PLS-DA）， the difference of P. mume carbon at different processing times was analyzed to determine the processing end point. RESULTS With the extension of processing time， the sample color gradually deepened； the chromaticity values L* and E* of the samples increased at first and then decreased， the chromaticity values a* and b* decreased， and finally all tended to be stable. The content of water-soluble extract， citric acid and tannin in the sample increased at first and then decreased， the water content of the sample decreased with time and finally stabilized. Correlation analysis showed that water， water-soluble extract， citric acid and tannin were positively correlated with L*， a*， b* and E*（P＜0.001）. PCA and HCA showed that P. mume carbon under different processing time could be clustered into two categories： the processed samples of 0-30 min and those of 40-60 min. PLS-DA showed that water and water-soluble extract were important quality indexes and b* was an important chrominance index in the processing of P. mume carbon. The chromaticity value of the samples processed for 50 min and 60 min were not significantly different. The contents of water， water- soluble extract， citric acid and tannin in the samples processed for 60 min were less than those processed for 50 min. CONCLUSIONS There is a certain correlation between the color and the inner quality of P. mume carbon. The processing time of P. mume carbon should be 40-50 min.

Objective:To investigate the risk factors of early death after lung transplantation in patients with idiopathic pulmonary fibrosis (IPF) complicated with pulmonary arterial hypertension (PAH).Methods:A retrospective cohort study was conducted. The clinical data of 134 patients with IPF and PAH who underwent lung transplantation at Wuxi People's Hospital Affiliated to Nanjing Medical University from January 2017 to December 2020 were collected. The donor's gender, age, duration of mechanical ventilation, and cold ischemia time, the recipient's gender, age, body mass index (BMI), smoking, history of hypertension and diabetes, preoperative usage of hormones, mean pulmonary arterial pressure (mPAP), cardiac echocardiography and cardiac function, serum creatinine (SCr), N-terminal pro-brain natriuretic peptide (NT-proBNP) as well as surgical type, extracorporeal membrane oxygenation (ECMO) treatment, duration of operation, and plasma and red blood cell infusion ratio were collected. The cumulative survival rates of patients at 30, 60, and 180 days after lung transplantation were calculated by Kaplan-Meier method. The univariate and multivariate Cox proportional hazards regression models were used to analyze the effects of donor, recipient, and surgical factors on early survival in donors after lung transplantation.Results:The majority of donors were male (80.6%). There was 63.4% of the donors older than 35 years old, 80.6% of the donors had mechanical ventilation duration less than 10 days, and the median cold ischemia time was 465.00 (369.25, 556.25) minutes. The recipients were mainly males (83.6%). Most of the patients were younger than 65 years old (70.9%). Most of them had no hypertension (75.4%) or diabetes (67.9%). The median mPAP of recipients was 36 (30, 43) mmHg (1 mmHg≈0.133 kPa). There were 73 patients with single lung transplantation (54.5%), and 61 with double lung transplantation (45.5%). The survival rates of 134 IPF patients with PAH at 30, 60, 180 days after lung transplantation were 81.3%, 76.9%, and 67.4%, respectively. Univariate Cox proportional risk regression analysis showed that recipient preoperative use of hormone [hazard ratio ( HR) = 2.079, 95% confidence interval (95% CI) was 1.048-4.128], mPAP ≥ 35 mmHg ( HR = 2.136, 95% CI was 1.129-4.044), NT-proBNP ≥ 300 ng/L ( HR = 2.411, 95% CI was 1.323-4.392), New York Heart Association (NYHA) cardiac function classification Ⅲ-Ⅳ ( HR = 3.021, 95% CI was 1.652-5.523) were the risk factors of early postoperative death in patients with IPF complicated with PAH (all P < 0.05). In the multivariable Cox proportional risk regression analysis, recipient preoperative hormone usage (model 1: HR = 2.072, 95% CI was 1.044-4.114, P = 0.037; model 2: HR = 2.098, 95% CI was 1.057-4.165, P = 0.034), NT-proBNP ≥ 300 ng/L ( HR = 2.246, 95% CI was 1.225-4.116, P = 0.009) and NYHA cardiac function classification Ⅲ-Ⅳ ( HR = 2.771, 95% CI was 1.495-5.134, P = 0.001) were independent risk factors of early postoperative death in patients with IPF. Conclusions:Preoperative hormone usage, NT-proBNP ≥ 300 ng/L, NYHA cardiac function classification Ⅲ-Ⅳ are independent risk factors for early death in patients with IPF and PAH after lung transplantation. For these patients, attention should be paid to optimize their functional status before operation. Preoperative reduction of receptor hormone usage and improvement of cardiac function can improve the early survival rate of such patients after lung transplantation.

Objective:To explore the effect of acute kidney injury(AKI)on near-term survival after lung transplantation(LT)in patients with idiopathic pulmonary fibrosis(IPF).Methods:Through consulting electronic medical records, anesthetic modes and Chinese Lung Transplant Registration System, clinical data are retrospectively reviewed for 275 IPF patients undergoing LT at Affiliated Wuxi People's Hospital of Nanjing Medical University from January 2017 to April 2021.According to the diagnostic criteria of Kidney Disease: Improving Global Outcomes(KDIGO), they are divided into two groups of AKI(169 cases)and non-AKI(106 cases).Perioperative findings of two groups are recorded.Then univariate and multivariate Cox regression models are employed for determining whether or not inter-group differences existed in survival rates post-LT.Also AKI is staged according to the KDIGO.And the effect of stage 1/2/3 AKI on near-term postoperative prognosis is examined.Results:The differences are significantly different in recipient gender, creatinine, 6-minute walking test, forced vital capacity(FVC), lung allocation score, oxygenation index, N-terminal pro-brain natriuretic peptide(NT-Pro BNP), preoperative hormone use and volume of crystal infusion( P<0.05).After multivariate Cox regression correcting for covariates, no statistical significance exists in effect of AKI stage 1 on near-term postoperative survival rate( P<0.05).AKI stage 2/3 still has statistical significance in risk of mortality at Day 30/90/180/365 post-operation( P>0.05). Conclusions:As a common complication post-LT, AKI significantly affects near-term postoperative prognosis of transplant IPF patients.Stage 2/3 AKI impacts near-term postoperative survival while stage 1 AKI is not associated with higher mortality.

Objective:To investigate the current situation and influencing factors of patients′ satisfaction with nursing humanistic care, and to provide reference for improving the quality of such care provided by hospitals.Methods:From July to August 2022, outpatients and inpatients in 30 provinces were selected by multi-stage stratified sampling as the survey objects. A cross-sectional survey was conducted on an online platform, using the general information questionnaire and Chinese version of methodist health care system nurse caring instrument revised by the research group. The latter instrument consists of 12 dimensions. namely care coordination, competence, teaching/learning, emotional support, respect for individuality, physical comfort, availability, helping/trusting relationship, patient/family engagement, physical environment, spiritual environment and outcomes. Descriptive analysis was performed on the data collected by the questionnaires, and independent sample t-test and one-way ANOVA were used to analyze the influencing factors of patient satisfaction. Results:A total of 107 hospitals were selected for questionnaire survey, including 86 tertiary hospitals and 21 secondary hospitals, and 29 108 valid questionnaires were recovered. The patient satisfaction with nursing humanistic care scored (5.40±0.86); the top three dimensions were competence (5.50±0.89), emotional support (5.47±0.88) and helping/trusting relationship (5.46±0.86); the lowest scoring dimensions were teaching/learning (5.38±1.01), spiritual environment (5.36±1.04) and patient/family engagement (5.11±1.28). Differences with gender, age, marital status, child status, educational level, occupation, place of residence, economic region, per capita monthly income of the family, type of medical insurance, medical department visited and surgery or not presented significant differences on the patient satisfaction with nursing humanistic care scores ( P<0.05). Conclusions:The satisfaction of patients with hospital′s nursing humanistic care in China was at the middle to upper level. In the future, health education for patients should be strengthened, and a mode of family-engaged nursing humanistic care should be constructed in line with the Chinese cultural background. In the process of nursing services, the particularity of patient groups should be considered to better meet their needs.
