Objective To understand the clinical applicability and implementation of expert consensus on the implementation and removal of protective restraints in psychiatry,and to provide references for promoting the standardized practice of psychiatric protective restraints and updating the consensus.Methods By the convenience sampling method,a questionnaire survey was conducted among nurses from 480 hospitals in 30 provinces from June 15 to July 15,2024.The survey was conducted using the instrument for evaluating clinical applicability of guide-lines(version 2.0)and a self-compiled questionnaire on the clinical implementation of the restraint consensus.Results A total of 7,844 valid questionnaires were collected,with a valid questionnaire recovery rate of 93.78％.The results of clinical applicability scoring showed that the consensus had the lowest availability score(64.72％)and the highest acceptability score(76.74％).The results showed that nurses' receiving training and the level of their hospitals were the main influencing factors for scores in various dimensions(P＜0.05).4,774 participants(87.42％)believed that the application of consensus could enhance the standardization of nurses' restraint operations.The safety rate of the restraint consensus was 79.51％,and the economic ratio was 76.87％.Among the evaluators,1,739(22.17％)believed that there were implementation obstacles in the consensus.Conclusion The clinical applicability of the consensus is relatively good,and the application of the consensus helps to improve the standardization of clinical operations.In the future,efforts should be made to strengthen the promotion and training of the consensus,develop hierarchical promotion strategies according to the characteristics of medical institutions,and improve the quality of evidence for the consensus,so as to further enhance the clinical application effect of the consensus.

Objective:To analyze the genetic characteristics of coxsackievirus A16 (CVA16) related to hand, foot and mouth disease (HFMD) in Jiaxing from 2021 to 2023, and understand the biological and molecular evolutionary characteristics of CVA16 in this city.Methods:Real-time fluorescent quantitative PCR was used to detect enterovirus and its types in collected HFMD case samples. At the same time, virus isolation and cultivation were performed on positive samples using RD cells. Then high-throughput sequencing of the whole genome was performed on 23 strains of CVA16 identified from the isolated samples. Finally we obtained its whole genome sequence. DNAStar, MEGA 6.0, Simplot 3.5.1 and other bioinformatics software were used to compare and analyze the sequences, construct the phylogenetic tree of VP1 region, and realize the genotype composition. And these software were also used to analyze the homology of the whole genome nucleotide sequence and the encoded amino acids, while know well the amino acid mutation sites and gene recombination in the main regions.Results:The results showed that among the 1 836 HFMD specimens tested from 2021 to 2023, 1 432 (78.00%, 1 432/1 836) were positive for enterovirus general genes, of which 263 were positive for CVA16, accounting for 18.37% (263/1 432) of the confirmed positive cases. Twenty-three CVA16 strains were sequenced and all of them were B1 subtype, of which 6 strains belong to B1b and 17 strains belong to B1a, with B1a being dominant. B1a strains in Jiaxing showed genetic relatedness to strains isolated in Beijing, Yunnan, Guangzhou, Jiangsu and other places in 2018 to 2023, as well as strains from Vietnam, Thailand, and Australia from 2015 to 2017. B1b strains exhibited consistent amino acid mutations of L23M in the VP1 region and V217I in the VP2 region, while B1a strains exhibited amino acid mutations of S14N/D, T164K, and V251I in the VP1 region and R41H in the VP3 region. Compared with the prototype strain, the 23 strains of CVA16 in Jiaxing accumulated the largest number of amino acid mutations in the coding region, with 28 and 50 mutations in the VP1 and 3D regions, respectively. The recombination patterns of B1a and B1b strains were slightly different, with B1a type showing recombination with CVA8 in the 5′-UTR region instead of CVA4, B1a was similar to enterovirus A71 in most of P2 and P3 regions, and recombined with CVA5 in the 3D region of P3.Conclusions:The prevalent strain of CVA16 in Jiaxing may share a common trend of co-circulation and evolution with those in other provinces. The recombination mainly occurs in the 5′-UTR region and non-structural protein coding regions of P2 and P3. Continuous molecular surveillance of CVA16 is in need, and whole-genome sequencing can help understand the genetic variation, evolution, and recombination of strains.This information will provide a more robust basis for the monitoring and early warning, vaccine development, and prevention and control efforts against HFMD.

Objective To investigate the proportions of myeloid-derived suppressor cells(MDSCs)and their subsets,including poly-morphonuclear MDSCs(PMN-MDSCs),early-stage MDSCs(e-MDSCs),monocytic MDSCs(M-MDSCs),and lectin-like oxidized low-density lipoprotein receptor-1(LOX-1)positive PMN-MDSCs,in the peripheral blood of ovarian cancer(OC)patients and ana-lyze their correlations with clinicopathological parameters of the patients.Methods The proportions of MDSCs and their subsets in the peripheral blood of 38 OC patients(OC group)and 46 healthy individuals(healthy control group)were detected by flow cytometry.The levels of serum IL-10 and TGF-β were detected using ELISA.The OC group was further divided into LOX-1 high and low expres-sion subgroups based on the median proportion of LOX-1+PMN-MDSCs in MDSCs.Results The proportions of MDSCs,PMN-MDSCs,and LOX-1+PMN-MDSCs in the peripheral blood mononuclear cells(PBMCs)of the OC group were significantly higher than those in the healthy control group(U=492,P＜0.001;t=8.741,P＜0.000 1;U=223,P＜0.000 1).The proportions of M-MDSCs and e-MDSCs in the OC group were significantly lower than those in the healthy control group(t=4.366,P＜0.000 1;t=6.927,P＜0.000 1).The proportion of LOX-1+PMN-MDSCs in the lymph node metastasis group of OC patients was significantly higher than that in the non-metastasis group(t=2.249,P＜0.05).The levels of serum IL-10 and TGF-β in the OC group were significantly higher than those in the healthy control group(P＜0.05).In addition,the level of serum TGF-β in the LOX-1 high expression group was significantly higher than that in the LOX-1 low expression group(t=2.302,P＜0.05).Conclusion The proportion of LOX-1+PMN-MDSCs in the peripheral blood of OC patients is significantly increased and closely related to lymph node metastasis.

Objective:To systematically review and evaluate prediction models for aspiration risk in enteral nutrition patients, providing a reference for the development and application of future models.Methods:Literature related to prediction models for aspiration risk in enteral nutrition patients was searched in China National Knowledge Infrastructure, Wanfang Data, China Biology Medicine disc, Web of Science, Cochrane Library, Embase, and PubMed, with the search period covering from the inception of the databases to August 30, 2024. Two researchers independently conducted literature screening and data extraction, and the PROBAST tool was used to assess the risk of bias and applicability of the included studies.Results:A total of 18 studies were included, involving 24 prediction models, with sample sizes ranging from 103 to 512 and an event rate of 9.46% to 49.87%. The top six predictive variables reported most frequently were baseline age, history of aspiration, length of nasogastric tube insertion, nutritional risk, impaired consciousness, and Acute Physiology and Chronic Health Evaluation-Ⅱscore. The area under the receiver operating characteristic curve of the models ranged from 0.756 to 0.992. Twelve studies reported model calibration, six studies conducted internal validation only, one study conducted external validation only, and four studies performed both internal and external validation. The overall applicability of the 18 studies was good, but the risk of bias was high, mainly due to improper handling of continuous variables and missing data.Conclusions:The aspiration risk prediction models developed in various studies for enteral nutrition patients show good applicability but carry a high risk of bias. Future efforts should focus on further optimizing the model construction process, internal and external validation, and result analysis to provide more reliable and scientific tools for clinical aspiration risk assessment.

Objective:To explore the dual mediating effects of health belief and depression among health knowledge, social support, and health behaviors based on the capacity, opportunity, motivation-behavior (COM-B) model, and analyze the influencing factors of health behaviors in patients with ischemic stroke.Methods:This multi-center cluster sampling research recruited ischemic stroke patients ( n=1 696) who were hospitalized in neurology departments of five tertiary hospitals in Henan Province from October 2023 to October 2024. A cross-sectional investigation was conducted using the general information questionnaire, social support rating scale (SSRS), stroke prevention knowledge questionnaire(SPKQ), short form health belief model scale(SF-HBMS), health promoting lifestyle profile-Ⅱ (HPLP-Ⅱ), and patient health questionnaire-9(PHQ-9) to ultimately reveal the pathways and effect sizes among variables. Partial correlation analysis and multiple linear stepwise regression analysis were conducted to examine the relationships among social support, health knowledge, health belief, health behaviors, and depression in stroke patients by SPSS 26.0 software. Structural equation modeling was constructed using AMOS 28.0 software, and the mediating effect was tested using the Bootstrap method. Results:The scores of social support, health knowledge, health belief, and health behaviors among ischemic stroke patients were (37.46±9.94), (26.56±6.84), (75.62±12.62) and (130.79±26.27), respectively. The score of depression was 5.00 (2.00, 8.00). Health behaviors were positively correlated with health knowledge, social support, and health belief( r=0.333, 0.246, 0.267, all P<0.05), while negatively correlated with depression ( r=-0.146, P<0.05). Multiple linear stepwise regression analysis showed that health knowledge, social support, health belief, and depression were all influencing factors of health behaviors in ischemic stroke patients (all P<0.05). Health belief (effect value=0.068, 95% CI=0.048-0.093) and depression (effect value=0.009, 95% CI=0.003-0.018) both played partial mediating roles between health knowledge and health behaviors, accounting for 17.3%(0.077/0.446) of the total effect. Meanwhile, health belief (effect value=0.045, 95% CI=0.029-0.063) and depression (effect value=0.016, 95% CI=0.008-0.027) both played partial mediating roles between social support and health behaviors, accounting for 26.5%(0.061/0.230) of the total effect. Conclusion:Health knowledge and social support can not only directly influence health behaviors but also indirectly affect them through health belief and depression in patients with ischemic stroke.

Objective:To investigate the efficacy and safety of a combination of programmed death receptor 1 (PD-1) inhibitor and multi-target tyrosine kinase inhibitor anlotinib in second-line treatment of non-small cell lung cancer (NSCLC).Methods:A prospective randomized controlled study was conducted. Using the random number table method, 118 NSCLC patients who were admitted to Shaanxi Provincial Cancer Hospital from June 2021 to June 2023 were randomly divided into the control group and the observation group, with 59 patients in each group. The observation group was treated with PD-1 inhibitor combined with anlotinib, while the control group was treated with PD-1 inhibitor. There were 36 males and 23 females in the observation group, with an age of (56±5) years; there were 34 males and 25 females in the control group, with an age of (56±5) years. There was no statistically significant difference in general clinicopathological data between the two groups (all P > 0.05). The short-term clinical efficacy [objective response rate (ORR) and disease control rate (DCR)], tumor-related factor levels [vascular endothelial growth factor (VEGF), matrix metalloproteinase 2 (MMP-2), tissue inhibitor of matrix metalloproteinase (TIMP), and tumor necrosis factor β1 (TNF-β1)], inflammatory status [plasma fibrinogen-to-albumin ratio (FAR)], lung function [forced vital capacity (FVC) and peak expiratory flow (PEF)] before and after treatment, the European Organization for Research and Treatment on Cancer (EORTC) core questionnaire for quality of life assessment (QLQ-C30) score, and occurrence of adverse reactions were compared between two groups of patients. Results:The ORR and DCR of the observation group were 33.90% (20/59) and 69.49% (41/59), respectively; the ORR and DCR of the control group were 10.17% (6/59) and 44.07% (26/59), respectively; the comparison of ORR and DCR between the two groups showed statistically significant differences ( χ2 values were 9.67 and 7.77, both P < 0.05). There was no statistically significant difference in the levels of tumor-related factors between the observation group and the control group before treatment (all P > 0.05); after 4 cycles of treatment, the levels of VEGF and MMP-2 in the observation group were lower than those in the control group, while the levels of TIMP and TNF-β1 were higher than those in the control group, and the differences were statistically significant (all P < 0.001). The FAR of the observation group and the control group before treatment were (0.15±0.06) g/L and (0.16±0.06) g/L, respectively, with no statistically significant difference ( t = 0.90, P = 0.367); after 4 cycles of treatment, the FAR were (0.07±0.01) g/L and (0.11±0.04) g/L, respectively, with statistically significant difference ( t = 7.45, P < 0.001). Before treatment, there was no statistically significant difference in FVC and PEF between the observation group and the control group (both P > 0.05); after 4 cycles of treatment, the FVC and PEF in the observation group were higher than those in the control group, and the differences were statistically significant (both P < 0.001). There were no statistically significant differences in the EORTC QLQ-C30 scores of functional dimension, symptom dimension and global health status/quality of life dimension between the observation group and the control group before treatment (all P > 0.05); after 4 cycles of treatment, the scores of functional dimension and global health status/quality of life dimension in the observation group were higher than those in the control group, while the symptom dimension score was lower than that in the control group, and the differences were statistically significant (all P < 0.001). The incidence of adverse reactions in the observation group was 6.78% (4/59), while in the control group it was 10.17% (6/59), and the difference was not statistically significant ( P = 0.741). Conclusions:The combination of PD-1 inhibitor and anlotinib in second-line treatment of NSCLC has good clinical efficacy, it can reduce the inflammatory response, improve the lung function and quality of life, and has good safety.

Objective:To investigate the value of quantitative parameters of dual-layer detector spectral CT (DLCT) in preoperative prediction of lymphovascular invasion (LVI) in invasive lung adenocarcinoma.Methods:This study employed a cross-sectional design. The data of 91 patients with primary lung adenocarcinoma confirmed by postoperative pathology who underwent DLCT enhanced scanning in the First Affiliated Hospital of Zhengzhou University from March 2022 to July 2024 were retrospectively collected. The patients were divided into LVI positive group and LVI negative group according to the postoperative pathology. Gender, age, smoking status, and lesion location were recorded,the clinical T-stage and N-stage were evaluated. Spectral base data images were generated based on the spectral reconstruction algorithm. Conventional CT features such as the size and density of the lesions were analyzed. The DLCT quantitative parameters such as 40 keV single-energy CT value (CT 40 keV), iodine density (ID), standardized iodine density (NID), and effective atomic number (Z eff) were measured. The differences of parameters between the two groups were compared using t-test, Mann-Whitney U test, or χ2 test. Multivariate logistic regression analysis was used to identify independent factors for predicting invasive lung adenocarcinoma LVI. The predictive performance of individual parameters and their combinations for LVI in invasive lung adenocarcinoma was evaluated using receiver operating characteristic curve analysis and area under the curve (AUC) measurements. Results:There were significant differences in age, T stage, N stage, maximum diameter, focal density, and arteriovenous stage NID and Z eff between the LVI positive group and the LVI negative group ( P<0.05). Multiple logistic regression analysis showed that age ( OR=0.890, 95% CI 0.821-0.966), N stage( OR=12.721, 95% CI 2.676-60.473) and venous stage Z eff( OR=0.012,95% CI 0-0.668) were independent factors for predicting invasive lung adenocarcinoma LVI ( P<0.05). The combination of age, N stage, and venous-phase Z eff values demonstrated the highest predictive efficacy for LVI in invasive lung adenocarcinoma, with an AUC of 0.916. Conclusions:The quantitative parameters of DLCT are helpful for preoperative prediction of LVI status of invasive lung adenocarcinoma. The Z eff in the venous stage is an independent predictor, the combination of multiple parameters can further improve the diagnostic efficiency.

Objective:This study aimed to compare short-chain fatty acid (SCFA) levels in saliva between patients with laryngopharyngeal reflux disease (LPRD) and healthy controls, and to explore the relationship between these SCFAs and the salivary microbiota.Methods:A retrospective case-control study was conducted, enrolling 36 patients with laryngopharyngeal reflux disease (LPRD) who visited the Department of Otorhinolaryngology Head and Neck Surgery, the Eighth Medical Center, Chinese PLA General Hospital between February and November 2023. All patients were diagnosed via pharyngeal pH monitoring. The LPRD group included 30 males and 6 females, aged 20-53 years (30.61±7.83 years). In addition, 39 healthy volunteers were recruited as the control group, comprising 25 males and 14 females, aged 18–58 years (28.64±7.97 years). Unstimulated mixed saliva samples were collected from all participants. Concentrations of eight SCFAs (acetic acid, propionic acid, isobutyric acid, butyric acid, valeric acid, isovaleric acid, hexanoic acid, and heptanoic acid) in saliva were quantified using gas chromatography-mass spectrometry (GC-MS). Salivary DNA was extracted, followed by amplification and sequencing of the 16S rRNA gene to analyze the microbiota composition at the genus level. The SCFA concentrations and the differences in bacterial species between the LPRD and control groups were compared, and the correlation between SCFA concentrations and the relative abundance of different bacterial genera in the salivary microbiota was analyzed. All statistical analyses were performed using R version 3.6.1 and SPSS version 26.0, while, microbiome analyses were conducted using R language.Results:Salivary hexanoic acid concentration was significantly higher in the LPRD group than in the control group [(29.50±19.61) ng/ml vs. (10.15±3.65) ng/ml; t=-2.72, P<0.05]. Significant differences in the relative abundance of 17 bacterial genera were observed between the two groups ( P<0.05), including Prevotella, Butyrivibrio, Streptococcus, and Actinomyces. Correlation analysis revealed that hexanoic acid concentration was significantly positively correlated with the abundance of Butyrivibrio (γ=0.73, P<0.05) and Streptococcus (γ=0.78, P<0.05), while showing a significant negative correlation with Actinomyces (γ=-0.73, P<0.05). Conclusion:Elevated salivary hexanoic acid levels may be associated with the development of LPRD. Dysbiosis of the salivary microbiota might contribute to LPRD pathogenesis by altering the concentrations of SCFA, particularly hexanoic acid.

Objective To explore the clinical efficacy and mechanism of FuKe Yangrong capsule(FKYRC)in treating anovulatory infertility(AI)using network pharmacology and clinical observation meth-ods.Methods A total of 110 AI patients who visited the hospital from January 2023 to July 2024 were select-ed as the research subjects.They were divided into three groups according to the treatment method:traditional Chinese medicine treatment group(n=30,treated only with FKYRC),western medicine treatment group(n=40,treated only with letrozole),and combination treatment group(n=40,treated only with FKYRC+letrozole).After 4 cycles of treatment,the total effective rate,maximum follicle diameter,pre-ovulation endo-metrial thickness,ovulation rate and pregnancy rate,and embryo survival rate of each group were compared af-ter treatment.Using the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform(TCMSP)and GeneCards database,the core active ingredients,target proteins,and AI related targets of FKYRC were obtained,and common targets were screened.Then,a protein-protein interaction(PPI)network was constructed,and gene ontology(GO)function and Kyoto Gene and Genome Database(KEGG)pathway enrichment analysis were performed using a bioinformatics platform for visualization.Finally,three-dimen-sional visualization analysis was performed.Results The total clinical efficacy of the traditional Chinese medi-cine group,western medicine group,and combination therapy group were 90.00％,92.50％,and 97.50％,re-spectively.The ovulation rates were 60.00％,70.00％,and 87.50％,respectively.The pregnancy rates were 33.33％,37.5％,and 60.00％,respectively.The survival rates of embryos were 60.00％,73.30％,and 95.80％,respectively,and the differences between the groups were statistically significant(P＜0.05).The maximum follicle diameter and pre-ovulation endometrial thickness in the combination therapy group were higher than those in the traditional Chinese medicine group and the western medicine group,and the difference was statistically significant(P＜0.05).Network pharmacology discovered 239 active ingredients and 3 977 target genes in FKYRC.After screening,200 active ingredients and 299 target genes were identified.A total of 478 disease target genes,38 potential interaction targets,and 19 core targets were obtained.Molecular func-tions,cellular components,and biological processes mainly involved steroid protein binding,estrogen response elements,estrogen receptor activity,nuclear chromatin,and other aspects.KEGG pathway enrichment analysis showed that FKYRC anti AI core targets were mainly enriched in estrogen signaling pathway,P53 signaling pathway,advanced glycation end product receptor(AGE-RAGE)of diabetes complications and other signaling pathways.The key targets of FKYRC against AI were two estrogen receptors(ESR1 and ESR2),steroid re-ceptor(AR),and peroxisome proliferator activated receptor-γ(PPARG).Conclusion The combined treat-ment of FKYRC and letrozole can improve AI patients' clinical symptoms,increase ovulation rate,pregnancy rate,and embryo survival rate.The active ingredients in FKYRC can comprehensively regulate the core targets of AI,and may promote follicular development and maturation in infertile patients with ovulation disorders through signaling pathways such as estrogen,P53,and AGE-RAGE,thereby increasing pregnancy rate.
