Objective:To construct an indicator system for the development of nursing disciplines in ClassⅢ Grade A general hospitals.Methods:An initial draft of the indicator system was established through literature research and expert meetings. The Delphi method and purposive sampling were used from January to April 2023 to conduct two rounds of expert consultations with 17 nursing experts from four medical units nationwide and three nursing colleges. The indicators were revised and refined, resulting in the establishment of a nursing discipline construction indicator system for ClassⅢ Grade A general hospitals. The level of expert engagement was represented by the questionnaire recovery rate, expert authority by the expert authority coefficient ( Cr), and the degree of expert opinion coordination by Kendall 's harmony coefficient (Kendall 's W) . Results:The recovery rates for both rounds of expert consultation questionnaires were 100.00% (17/17), with expert Cr of 0.87. The CV values ranged from 0.049 to 0.260 and 0 to 0.140, respectively, while Kendall 's W were 0.221 and 0.257 ( P< 0.01). The final indicator system for the construction of nursing disciplines in ClassⅢ Grade A general hospitals included six primary indicators, 18 secondary indicators, and 63 tertiary indicators. Conclusions:The nursing discipline construction indicator system developed for ClassⅢ Grade A general hospitals in this study is scientific, reliable, and comprehensive. It can provide a reference for the construction of nursing disciplines in Class Ⅲ Grade A general hospitals.

The imbalance of microbiota is related to various diseases in the human body,and the gut,as the largest microbial habitat in the human body,is closely related to the oral microbial environment.The oral microbiota can migrate to the intestinal mucosa with the digestive system.At the same time,microbial transmission from the gut to the mouth can also occur through interpersonal and com-munity transmission.Microbial transmission between the mouth and intestines can shape or reshape the microbial ecosystem in the two habitats,ultimately regulating the pathogenesis of the disease.The dysbiosis of the oral-gut microbiota axis can have a significant impact on related diseases such as respiratory diseases.This article reviews the research status of the relationship between oral-gut microbes and respiratory diseases.

Flowering is a critical transitional stage during plant growth and development, and is closely related to seed production and crop yield. The flowering transition is regulated by complex genetic networks, whereas many flowering-related genes generate multiple transcripts through alternative splicing to regulate flowering time. This paper summarizes the molecular mechanisms of alternative splicing in regulating plant flowering from several perspectives, future research directions are also envisioned.

To address the increasing need for detecting and validating protein biomarkers in clinical specimens, mass spectrometry (MS)-based targeted proteomic techniques, including the selected reaction monitoring (SRM), parallel reaction monitoring (PRM), and massively parallel data-independent acquisition (DIA), have been developed. For optimal performance, they require the fragment ion spectra of targeted peptides as prior knowledge. In this report, we describe a MS pipe-line and spectral resource to support targeted proteomics studies for human tissue samples. To build the spectral resource, we integrated common open-source MS computational tools to assemble a freely accessible computational workflow based on Docker. We then applied the workflow to gen-erate DPHL, a comprehensive DIA pan-human library, from 1096 data-dependent acquisition (DDA) MS raw files for 16 types of cancer samples. This extensive spectral resource was then applied to a proteomic study of 17 prostate cancer (PCa) patients. Thereafter, PRM validation was applied to a larger study of 57 PCa patients and the differential expression of three proteins in prostate tumor was validated. As a second application, the DPHL spectral resource was applied to a study consisting of plasma samples from 19 diffuse large B cell lymphoma (DLBCL) patients and 18 healthy control subjects. Differentially expressed proteins between DLBCL patients and healthy control subjects were detected by DIA-MS and confirmed by PRM. These data demonstrate that the DPHL supports DIA and PRM MS pipelines for robust protein biomarker discovery. DPHL is freely accessible at https://www.iprox.org/page/project.html?id=IPX0001400000.

Objective: To analyze the change trend of HIV genetic subtypes and compare the first CD₄⁺T cell counts of newly diagnosed HIV infected patients in Liuzhou from 1998 to 2012, and provide a reference for AIDS prevention and control. Methods: Newly diagnosed HIV-infected patients from 1998 to 2012 in Liuzhou were selected through national HIV/ADIS comprehensive response information management system. Their plasma samples were used for RNA gene extraction, amplification, sequencing and genotyping. Coharan-Armitage trend test was used to analyze the ratio trend of genetic subtypes and phylogenetic clusters of HIV and Wilcoxon Rank Sum Test was used to compare the first CD₄⁺T cell counts (CD₄) of the different subtype HIV infected patients. Results: A total of 1 877 newly diagnosed HIV infected patients were included in the study. From 1998 to 2012, the proportions of CRF01_AE and CRF01_AE (Cluster 1) increased from 78.4% (76/97) to 91.5% (1 441/1 574), from 63.9% (62/97) to 74.0% (1 164/1 574), and the proportion of CRF07_BC decreased from 17.5% (17/97) to 4.6% (72/1 574), respectively (Z=4.632, P<0.001; Z=2.455, P=0.014; Z=-5.943, P<0.001). The median and interquartile range of the first CD₄ of the patients infected with subtype CRF01_AE (Cluster 1), CRF01_AE (Cluster 2), CRF07_BC and CRF08_BC were 230 (83-375), 215 (48-351), 365 (254-503) and 334 (206-479) cell/μl, respectively. The first CD₄ levels of the patients infected with subtype CRF01_AE (Cluster 1) or CRF01_AE (Cluster 2) were significantly lower than those of CRF07_BC (Z=-4.795, P<0.001; Z=-4.238, P<0.001). Conclusion The genetic subtypes of HIV were mainly CRF01_AE in newly diagnosed HIV-infected patients and this subtype proportion was in increase and the first CD₄ levels of the patients were low in Liuzhou during 1998 to 2012.

Objective To explore the feasibility of blood oxygen level-dependent (BOLD) MRI to detect the chronic hepatitis b-induced early kidney injury. Methods Seventeen clinically diagnosed chronic hepatitis b patients with early kidney injury and 10 healthy volunteers were enrolled in this preliminary study. The 17 patients underwent dynamic nuclear renography and then subdivided into stage 1 kidney injury group (n=7) and stage 2 kidney injury group (n=10). All of the enrolled subjects underwent BOLD examination and T2* relaxation rates (R2*) of renal cortex and medulla of split kidney, and the ratio between them (R2*med/cor) were measured separately. One-way analysis of variance (ANOVA) were performed on the control group and chronic hepatitis b patients group (kidney injury stage 1 and stage 2 group) to compare the difference of renal cortical and medullary R2*values and R2*med/cor ratio. ROC curves were used to evaluate the efficacy of renal cortical and medullary R2* values and R2*med/cor ratio to diagnose the chronic hepatitis b-induced kidney injury. Results The cortical R2*values of control group, stage 1 kidney injury group and stage 2 kidney injury group were(16.87 ± 0.74)/s,(17.88 ± 0.73)/s,(20.29 ± 2.87)/s, respectively;the medullar R2*values of control group, stage 1 kidney injury group and stage 2 kidney injury group were (28.07±1.03)/s,(31.14±2.49)/s,(32.81±3.28)/s, respectively;R2*med/cor of the of control group, stage 1 kidney injury group and stage 2 kidney injury group were 1.67 ± 0.09, 1.75 ± 0.16, 1.63 ± 0.13, respectively, and the differences among the three groups were statistically significant (F values were 17.779, 19.170 and 3.439 , all P<0.05). Furthermore, the renal cortical and medullary R2* values of chronic hepatitis b patients were significantly higher than the control group, and the the renal cortical R2* value of the patients in stage 2 kidney injury group was also higher than the stage 1 kidney injury group. The area under curve (AUC) of ROC of the renal cortical and medullary R2*values and R2*med/cor to diagnose chronic HBV hepatitis-induced early kidney injury were 0.903, 0.949 and 0.526, respectively. Conclusion It's feasible and has great value to use renal BOLD MRI for the diagnosis of chronic hepatitis b-induced early kidney injury, and the renal cortex is more sensitive than the medulla to the kidney injury.

Objective To investigate the mediating effect of the positive and the negative strategy of cognitive emotion regulation on the relationship between life events and suicide ideation among college students,as well as the moderating effect of social support on the mediation model.Methods Participants were 2 471 college students in Hunan province,and they completed the Adolescent Self-rating Life Events Check List,the Cognitive Emotion Regulation Questionnaire, the Social Support Scale for university students and the Suicide Ideation Questionnaire for university students .Results Negative strategy of cognitive emo-tion regulation played a mediating role between life events and suicide ideation among college students (β=0.17, t=8.43, P<0.01).Mediating effect quoted 0.28×(0.18-0.05U).Social Support (U) played a moder-ating role on the second path of mediation (β=-0.05, t=-2.47, P<0.05) .When U changed one unit,medi-ating effect changed 0.05 unit.Conclusion Life events influence suicide ideation through negative strategy, and with social support increasing,the effect of negative strategy on suicidal ideation weakened.

Objective To explore the effects of self-differentiation,social support,social adaptation on suicidal ideation.Methods A simplified cluster sampling method,involving the random selection of 3097 college students in 23 departments,was used to estimate the scores of Chinese version of Self Differentiation Inventory for university student(SDI),Social Support Rating Scale(SSRC),College Student Adaptability Scale (CSAS) and Adult Suicidal Ideation Questionnaire(ASIQ).The independent-samples t-test,Pearson correlation coefficients and stepwise regression analyses were used as statistical analysis techniques.Results The correlation coefficients were negatively significant between suicidal ideation and self-differentiation,social support and social adaptation (r=-0.24,-0.17,-0.29,P＜0.001).Social adaptation showed the strongest predictability for suicidal ideation (β=-0.19,P＜0.001),followed by self-differentiation (β3=-0.13,P＜0.001),social support (β3=-0.08,P＜0.001).Independent samples t-test showed that college students with suicidal ideation showed a significant reduction in interpersonal adaptation,social support,self-differentiation compared to those without suicidal ideation.Conclusion Self-differentiation level,social support and social adaptability may be effective predictors for suicidal ideation among college students.Future intervention programs may focus on enhancing the interpersonal skills of college students to reduce prevalence of suicidal behavior.
