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）］

Objective To analyze the correlation of inflammatory indicators of neutrophil-to-lymphocyte ratio(NLR),platelet-to-lymphocyte ratio(PLR),monocyte-to-lymphocyte ratio(MLR),and systemic immune-inflammation index(SII)with traditional Chinese medicine(TCM)syndrome types and Chinese version of Thyroid Imaging Reporting and Data System(C-TIRADS)classification and properties of nodules in the patients with thyroid nodules(TN),thus to provide evidence for guiding TCM syndrome differentiation and treatment,and for assessing C-TIRADS classification and properties of the nodules in patients with TN.Methods A retrospective analysis was carried out in 140 inpatients who were diagnosed as TN and had underwent thyroidectomy during the period of January 2021 to January 2024 in the Department of General Surgery of Guangzhou Integrated Chinese and Western Medicine Hospital Affiliated to Guangzhou University of Chinese Medicine(Guangzhou Hospital of Integrated Traditional and West Medicine).The patients were allocated to various group with reference to TCM syndrome types,C-TIRADS classification,and the properties of TN.The correlation of each clinical indicator with TCM syndrome types and C-TIRADS classification and properties of TN was analyzed.The Spearman correlation coefficient was employed for evaluating the correlation of clinical indicators with the C-TIRADS classification and properties of TN,receiver operating characteristic curve(ROC)was used to analyze the predictive value of NLR,MLR,PLR,and SII for the properties of nodules in patients with TN,and the Youden's Index was used to determine the cutoff value for optimal prediction.Results(1)According to the criteria of TCM syndrome differentiation,72 cases were differentiated as qi stagnation and phlegm obstruction syndrome,65 cases as phlegm accumulation and blood stasis syndrome,and 3 cases as heart-liver yin deficiency syndrome.For the number of cases of heart-liver yin deficiency syndrome was too small,only the first two syndromes were included for the analysis.(2)The levels of free T3(FT3)and free T4(FT4)in the patients of qi stagnation and phlegm obstruction syndrome were higher,and the levels of anti-thyroid peroxidase antibody(A-TPO),anti-thyroglobulin antibody(A-TG),neutrophil(NEU),NLR,and SII were lower than those in the patients of phlegm accumulation and blood stasis syndrome,the differences being all statistically significant(P<0.05 or P<0.01).(3)The levels of NLR,PLR,and SII in the patients with C-TIRADS3 classification were lower than those in the patients with C-TIRADS4 classification,the differences being all statistically significant(P<0.05 or P<0.01);no statistically significant difference of MLR was presented between the patients with C-TIRADS3 classification and those with C-TIRADS4 classification(P>0.05).(4)The levels of NLR,PLR,MLR,and SII in patients with benign nodules were lower than those in patients with malignant nodules,the differences being statistically significant(P<0.05 or P<0.01).(5)The Spearman correlation analysis showed that NLR,PLR,and SII were positively correlated with the C-TIRADS classification of the nodules,and NLR,PLR,MLR,and SII were positively correlated with the properties of the nodules,the differences being all statistically significant(P<0.05 or P<0.01).(6)The levels of NLR,MLR,PLR,and SII in patients with high-risk TN exerted a certain predictive value for the properties of the nodules,and their area under the curve(AUC)was 0.645,0.641,0.604,and 0.716,respectively,the differences being statistically significant(P<0.05 or P<0.01).For the prediction of nodule properties by NLR,MLR,PLR,and SII levels in patients with high-risk TN,their cutoff values and the corresponding sensitivities and specificities were 2.261(0.551,0.791),138.108(0.735,0.527),5.132(0.714,0.495),493.114(0.776,0.615),respectively;and their Youden's Index was 0.342,0.262,0.209,0.391,respectively.Conclusion The results indicated that in patients with TN,the FT3 and FT4 levels are positively correlated with the qi stagnation and phlegm obstruction syndrome;the values of A-TPO,A-TG,NEU,NLR,and SII are positively correlated with the phlegm accumulation and blood stasis syndrome;NLR,PLR and SII values are positively correlated with C-TIRADS classification;NLR,PLR,PLR,SII values are positively correlated with malignant TN.NLR,MLR,PLR,SII values exert high efficiency for the prediction of the properties of nodules in patients with TN.

Objective To explore the need and evaluate the effectiveness for head-simulator in the teaching of sto-matology within the eight-year program of clinical medicine.Methods Questionnaire survey was conducted among the students from 2017 cohort of the eight-year program of clinical medicine at Peking Union Medical College.The survey results were statistically analyzed and described.Results Totally 87.9％of the students believed that incor-porating head-simulator into the clinical practice course of stomatology were necessary,and 93.9％expressed will-ingness to join the training.Most students preferred to practice peri-odontal scaling and cavity preparation for caries during the simulated training sessions.The majority of students considered two or four class hours of simulated head teaching to be reasonable.The pilot head simulation training was successfully implemented;75.0％of the students acknowledged clear teaching and convincible demonstrations.All the trainees agreed that the head simulation course helped them better understand stomatology knowledge,stimulated their interest in learning and expressed a desire for increased head simulation sessions during clinical practice course of stomatology.Additionally,87.5％of the students preferred head simulation training course to be applied in classic clinical clerkships.Conclusions There is strong demand among students of eight-year program of clinical medicine for incorporating head-simulator into the education of stomatology.The pilot simulation training received positive evaluations.Further exploration is needed to optimize specific scheduling and content arrangement.

Objective To evaluate the high-risk factors for venous thromboembolism(venous throm-boembolism,VTE)during the perioperative period in gynecology and analyze the rationality of anticoagulant drug use.Methods Clinical data of 183 gynecological surgical patients treated at Kunming Maternal and Child Health Hospital from January 2023 to December 2024 were collected.Among them,29 diagnosed with postoperative VTE were classified as the VTE group and 154 diagnosed with no postoperative VTE during the same period were classified as the non-thrombosis group.Independent sample t-test,Mann-Whitney U test,or χ2 test were used to analyze high-risk factors for VTE during the perioperative period.Logistic regression analysis was employed to identify risk factors for VTE after the gynecological surgery and a predictive regression model was established.The ROC curve was plotted to evaluate the model's validity.Results Elevated D-dimer levels,open abdominal surgery,and history of thrombosis were independent risk factors for VTE in postoperative gynecological patients(OR>1,P<0.05).The AUC of the regression-based predictive model was higher than that of the Caprini and G-Caprini scores,indicating that this model had the good discriminatory ability its resolution was better than G-Caprini and Caprini risk assessment tools.The identified issues in VTE prophylaxis at the hospital included the insufficient mechanical prevention time limit and delayed initiation of anticoagulant therapy in patients at moderate risk of bleeding.Conclusion This predictive model has certain clinical value for broader application.For issues related to drug therapy such as delayed use of anticoagulant drugs,clinical pharmacists should collaborate with physicians to assess patients'bleeding and thrombosis risks,jointly develop precise anticoagulation regimens.

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.

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: Scutellarin is a primary active composition come from Erigeron breviscapus. It is well known that scutellarin has anti-inflammatory and antioxidant physiological functions. In this study, we detected the effects of scutellarin on hepatocyte cell apoptosis in type 2 diabetes mellitus (T2DM) rats. METHODS: Sprague Dawley (SD) (6-8 weeks, 160-180 g) rats were randomly divided into six groups: control, model, scutellarin low-dose, medium-dose, high-dose treatment, and rosiglitazone positive groups; with 10 SD rats in each group (n = 10). The changes of biochemical factors in serum were detected by automatic biochemical instrument, the pathological changes of liver tissue were detected by hematoxylin and eosin (HE) staining, the apoptosis of liver tissue and cells was detected by tissue staining and flow analyzer, and the expression of apoptosis-related factors were determined by qPCR, Western blot and immunohistochemistry in liver tissues or cells. RESULTS: The results showed that scutellarin decreased the levels of fasting blood glucose, total cholesterol, triglyceride, and low-density lipoprotein and increased the levels of high-density lipoprotein. Meanwhile, scutellarin decreased the levels of alanine transaminase (ALT) and aspartate transaminase (AST) and improved liver function. In addition, scutellarin suppressed the secretion of interleukin-1 (IL-1), interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) and reduced hepatocyte apoptosis. Furthermore, scutellarin inhibited the expression of cleaved Caspase-3, Bax, and cytochrome C (Cyt-C) and promoted the expression of Bcl-2. CONCLUSION Scutellarin can inhibit the apoptotic pathway, thereby relieving T2DM.
