ObjectiveTo explore the effectiveness of feedforward control mode on improving occupational burnout among operating room nurses through theoretical research and clinical practice， with a view to promoting their physical and mental health and enhancing the quality of surgical nursing. MethodsA total of 440 operating room nurses from different regions， scales， and nursing experiences in Shaanxi Province from November 2023 to December 2023 were randomly divided into an experimental group and a control group， with 220 nurses in each group. While the control group received routine intervention measures， the experimental group introduced a feedforward control mode based on the control group， with “emotional exhaustion，” “depersonalization，”and“personal achievement” as observation indicators. ResultsThe incidence of occupational burnout in the experimental group was 11.4%， while that in the control group was 20.0%. The experimental group showed a significantly lower incidence than the control group （P=0.013）. ConclusionThe feedforward control mode can significantly alleviate nurses’ sense of job burnout， promote the improvement of surgical nursing quality， as well as continuously improve the scientific rigor， advancement， and humanistic nature of nursing services， which is conducive to building a harmonious and efficient nursing team. The spirit of teamwork， reflected in mutual support， mutual trust， and joint efforts for surgical success and patient health， has become an important component of nurses’ professional ethics.

Objective To explore the developmental trajectories of oral hygiene compliance and its influencing factors in children after dental caries surgery.Methods A prospective cohort study design was adopted.A total of 268 children who underwent dental caries surgery were selected as the research subjects.General and clinical data of the children were collected.The oral hygiene compli-ance changes after surgery were evaluated using the Oral Hygiene Compliance Scale.The develop-mental trajectories of oral hygiene compliance after surgery were described using the group-based traj-ectory model.Multivariate Logistic regression analysis was used to explore the influencing factors of the compliance developmental trajectories.Results The oral hygiene compliance of children after dental caries surgery could be divided into three types of developmental trajectories:the high-compliance slow-decline group[49(18.28％)],the medium-compliance slow-decline group[56(20.90％)],and the low-compliance stable-change group[163(60.82％)].Multivariate Logistic regression analysis showed that the child's gender,mother's educational level,fathers smoking history,annual per capi-ta household income,Social Support Scale score,Oral Health Self-Efficacy Scale score,and Expec-ted Social Impact Scale score were all independent influencing factors for the oral hygiene compliance to present different types of developmental trajectories(P＜0.05).Conclusion The oral hygiene compliance of children after dental caries surgery presents different types of developmental trajectories,and there are individual differences in their initial compliance levels and rates of change.Clinically,oral hygiene care intervention measures should be implemented according to the specific conditions of children to maintain their oral health.

A quantitative analytical method was established for 275 kinds of metabolites in plasma based on ultra-high performance liquid chromatography-triple quadrupole mass spectrometry/multiple reaction monitoring-selected ion monitoring(UHPLC-QQQ-MS/MRM-SIM)technique.Based on UHPLC-high resolution(HRMS)/full MS-parallel reaction monitoring(PRM)technique,165 kinds of lipid metabolites in plasma were qualitatively identified and quantitatively detected to address the analytical challenges of lipid isomers.This quantitative metabolomics approach was successfully applied to a rat myocardial infarction study,identifying and quantifying 372 kinds of metabolites in total.Comparative analysis with the sham-operated group revealed significant alterations in 59 kinds of plasma metabolites in myocardial infarction rats.Key metabolic pathways,which included amino acid metabolism(alanine,aspartate,and glutamate metabolism;glycine,serine,and threonine metabolism,etc.),one-carbon unit metabolism,and tricarboxylic acid cycle,were significantly disrupted.

Objective To investigate the distribution of traditional Chinese medicine(TCM)syndrome types in patients with primary Sj?gren's syndrome(PSS),and to explore the correlation between TCM syndrome types and laboratory findings of immunological parameters and inflammatory cytokines.Methods A retrospective study was conducted on 326 patients with PSS who attended the Department of Rheumatology of Yueyang Hospital of Integrated Traditional Chinese and Western Medicine,Shanghai University of Traditional Chinese Medicine,from January 2018 to December 2022.Analysis was carried out for the distribution of TCM syndrome types,namely yin deficiency and blood dryness syndrome,deficiency of qi and yin syndrome,internal retention of damp-heat syndrome,and stagnant heat in the collateral syndrome,in PSS patients.The gender,age of onset,and duration of disease of PSS patients with different TCM syndrome types were compared.And then an exploration was performed in the correlation between TCM syndrome types and laboratory findings of Sj?gren's syndrome antigen A antibody(anti-SSA),Sj?gren's syndrome antigen B antibody(anti-SSB),C-reactive protein(CRP),erythrocyte sedimentation rate(ESR),immunoglobulin G(IgG),immunoglobulin A(IgA),interleukin 6(IL-6),complement 3(C3)and complement 4(C4).Results(1)The analysis of the distribution of TCM syndrome types showed that among the 326 patients,106 cases(32.5%)were differentiated as internal retention of damp-heat syndrome,which accounted for the most,and then came yin deficiency and blood dryness syndrome(84 cases,25.8%),stagnant heat in the collateral syndrome(78 cases,23.9%),and deficiency of qi and yin syndrome(58 cases,17.8%)in descending order.(2)There was no statistically significant difference in the gender among the PSS patients with different TCM syndrome types(P>0.05),but the differences of age of onset and the duration of disease among the PSS patients with different TCM syndrome types were statistically significant(P<0.05).The distribution of duration of disease and age of onset in the PSS patients with yin deficiency and blood dryness syndrome,deficiency of qi and yin syndrome,and stagnant heat in the collateral syndrome,internal retention of damp-heat syndrome was in descending order.(3)The analysis of the correlation between TCM syndrome types and laboratory findings showed that yin deficiency and blood dryness syndrome was positively correlated with anti-SSB,IgA,IgG,and C4;deficiency of qi and yin syndrome was positively correlated with anti-SSB,IgG,and C4;internal retention of damp-heat syndrome was positively correlated with CRP,ESR,IL-6,anti-SSA,and IgA;stagnant heat in the collateral syndrome was positively correlated with CRP,ESR,IL-6,and anti-SSA.The differences were all statistically significant(P<0.05 or P<0.01).Conclusion The patients with PSS are usually differentiated as internal retention of damp-heat syndrome,patients with yin deficiency and blood dryness syndrome and deficiency of qi and yin syndrome usually have longer duration of disease and older age of onset,and the patients with internal retention of damp-heat syndrome and stagnant heat in the collateral syndrome usually have shorter duration of disease and younger age of onset.The laboratory findings such as immunological parameters and inflammatory cytokine are correlated with TCM syndrome types of PSS patients to some extent,which will supply guidance for the clinical differentiation of TCM syndromes of PSS.

Objective:To investigate the genetic causal relationship of leukocyte telomere length(LTL)with prostatitis,orchi-tis and epididymitis by two-sample Mendelian randomization(MR).Methods:Using LTL as the exposure factor and prostatitis,or-chitis and epididymitis as outcome factors,we mined the Database of Genome-Wide Association Studies(GWAS).Then,we analyzed the causal relationship of LTL with prostatitis,orchitis and epididymitis by Mendelian randomization using inverse variance weighting(IVW)as the main method and weighted median and MR-Egger regression as auxiliary methods,determined the horizontal multiplicity by MR-Egger intercept test,and conducted sensitivity analysis using the leaving-one-out method.Results:A total of 121 related sin-gle nucleotide polymorphisms(SNPs)were identified in this study.IVW showed LTL to be a risk factor for prostatitis(OR=1.383,95％CI:1.044-1.832,P=0.024),and for orchitis and epididymitis as well(OR=1.770,95％CI:1.275-2.456,P=0.000 6).Conclusion:Genetic evidence from Mendelian randomized analysis indicates that shortening of LTL reduces the risk of prostatitis,orchitis and epididymitis.

Sit-to-stand is an indispensable functional activity in human daily life, which requires high muscle strength, not only to control the lower limbs, but also to ensure the stable ascension of the trunk. This paper describes in detail the trajectory and speed of the joints through the human sit-to-stand test, analyzes the change rule of the angle of the joints, the angular velocity and the position of the center of mass in the human sit-to-stand, and records in detail the change of the plantar pressure of the subjects in this process. Through the study on joint motion and plantar pressure changes in the process of sit-to-stand, this paper summarizes the kinematics of human body in this process, aiming to provide a basis through the results of this paper for the design of human sit-to-stand assistive devices, which may be used in the future to analyze the sit-to-stand state of patients with lower limb disorders, and carry out the corresponding treatment and rehabilitation training.
