ObjectiveTo analyze the diversity and structural characteristics of microbial communities in the rhizosphere soil of healthy and diseased Andrographis paniculata and to explore the interactions of soil， plants， and microorganisms during the occurrence of diseases. MethodsThe physicochemical properties of the rhizosphere soil of healthy and diseased A.paniculata were determined， and the composition and diversity of bacterial and fungal communities in the rhizosphere soil were analyzed by Illumina high-throughput sequencing. Furthermore， the correlations between physicochemical properties and microorganisms of the rhizosphere soil were explored. ResultsThe content of total nitrogen， total potassium， and available potassium in the rhizosphere soil of diseased A. paniculata was significantly higher than that of healthy A. paniculata. The alpha diversity and richness （operational taxonomic units） of bacterial and fungal communities in the rhizosphere soil of diseased plants decreased compared with those of healthy plants. The microbial communities in the rhizosphere soil of healthy and diseased A. paniculata showed similar composition but different relative abundance. At the phylum level， the relative abundance of Proteobacteria and Chytridiomycota significantly increased， while that of Bacteroidota significantly decreased in the rhizosphere soil of diseased plants. At the genus level， the relative abundance of Sphingomonas， Pseudomonas， and Bryobacter significantly increased， while that of RB41 showed a significant decrease in the rhizosphere soil of diseased plants. The correlation analysis showed different correlations of microbial phyla with physicochemical properties of the rhizosphere soil between healthy and diseased plants. Organic matter， alkaline nitrogen， available phosphorus， and total potassium were correlated with the relative abundance of some dominant bacterial and fungal phyla in the rhizosphere soil of healthy plants， while available nitrogen and total phosphorus were correlated with the relative abundance of some dominant bacterial and fungal phyla in the rhizosphere soil of diseased plants. ConclusionThere are differences in the diversity and richness of microbial communities in the rhizosphere soil of healthy and diseased A. paniculata. The physicochemical properties of soil may have an impact on the rhizosphere microorganisms of A. paniculata， leading to the development of diseases. The results provide a scientific basis for the prevention and ecological management of A. paniculata diseases.

Objective:To explore the cognition and intention of patients with lower limb deep vein thrombosis (DVT) to participate in patient-reported outcomes (PROs), so as to provide references for the promotion, application, and practice of PROs in lower limb DVT patients in China.Methods:This study adopted the phenomenological qualitative research method. From February to June 2023, 13 lower limb DVT patients admitted to Peking Union Medical College Hospital were selected for semi-structured in-depth interviews. Colaizzi 7-step analysis method was used for analyzing and summarizing data.Results:Thirteen patients with lower limb DVT highly recognized their own value in participating in PROs, namely health benefits, prevention of DVT complications, and reduction of disease uncertainty. Lower limb DVT patients expected to receive support from healthcare professionals, families, and portable and simplified reporting formats to promote their participation in PROs. From the patient 's own perspective, they perceived that insufficient attention to DVT caused by lack of awareness of the hazards of DVT and limited understanding of PROs made it difficult for them to participate in PROs. Conclusions:Lower limb DVT patients have a high intention to participate in PROs. The application and promotion of PROs in lower limb DVT patients in China require joint support from various sectors of society, among which strengthening effective health education for patients and their families and providing multi-channel reporting forms are the key to promoting of PROs.

Objective To construct an evidence-based practice model for nurses in preventing deep vein thrombosis(DVT)and provide a scientific and targeted theoretical basis for nurses to carry out evidence-based nursing practice in DVT prevention.Methods Based on the previous evidence-based nursing practice project on DVT prevention after hip and knee arthroplasty,the research team used theoretical analysis and brainstorming to develop a draft of the work model.Expert meetings were organized to validate the content of the draft using the Delphi method,leading to the finalization of the evidence-based practice model for nurses in preventing DVT.Results The Knowledge-to-Action(KTA)framework was selected as the basic framework for constructing the evidence-based nursing practice model for preventing DVT.Theoretical Domain Framework,Theory of Planned Behavior,and Social Cognitive Theory were chosen to explore the influencing factors of nurses'behavior change in preventing DVT through evidence-based practice.The authority coefficient of the participating experts was 0.904,indicating high reliability.The final model consisted of 6 key components:knowledge generation,problem identification,localization and adaptation,knowledge application,sustained knowledge use,and conceptual framework for behavior change through evidence-based practice.Conclusion Based on theoretical analysis and clinical practice,this study developed an evidence-based practice model for nurses in preventing DVT using the expert meeting.The research methodology was scientific,and the content was reliable,providing a theoretical basis for nurses to engage in evidence-based nursing practice for DVT prevention.

Objective The long-term epidemiological and etiological characteristics of hand, foot and mouth disease (HFMD) in Huai’an, Jiangsu were analyzed to provide scientific evidence for the prevention of HFMD. Methods The data of HFMD reports, etiological diagnosis and in Huai’an from 2009 to 2022 were described and analyzed. Results A total of 78 535 cases were reported from 2009 to 2022 , with 14-year average annual incidence rate of 114.71/100 000. Before 2020, the incidence rate of HFMD in Huai’an showed the epidemic intensity increased every other year on the whole, and the average annual incidence rate during the COVID-19 pandemic (2020-2022) (55.69/100 000) was significantly lower than that in previous years (2009-2019) (129.95/100 000). The joinpoint regression analysis showed that the best fitting model from 2009 to 2022 had no joinpoints, APC=AAPC=-1.24%. The overall trend showed a monotonously decreasing trend, but the trend was not statistically significant. The male-to-female distribution ratio was 1.53:1, and the age distribution was mainly under 5 years old, especially in scattered children. The epidemic season was from April to July. The results of etiological surveillance showed that the co-epidemic of Coxsackievirus A16 (CV-A16) and Enterovirus A71 (EV-A71) during the early stages had changed to the co-epidemic of CV-A16 and CV-A6 in the current period. Conclusion The burden of HFMD in Huai’an was large, and the epidemic intensity increased every other year was affected by the COVID-19 pandemic. The epidemiological features after the COVID-19 pandemic should be further monitored.

Objective To explore the relationship between haptoglobin gene polymorphism and disease se-verity and susceptibility in senile vascular dementia patients.Methods A total of 80 patients with senile vas-cular dementia admitted to the hospital from February 2018 to February 2023 were selected as the vascular de-mentia group,and 80 stroke patients with non-vascular dementia admitted to the hospital during the same pe-riod were selected as the control group.The genotype distribution and allele frequency of haptoglobin gene were measured using polymerase chain reaction with sequence-specific primers,and their relationship with the severity and susceptibility of vascular dementia patients was analyzed.Results The proportion of history of hyperlipidemia and diabetes mellitus and the levels of total cholesterol and triglyceride in vascular dementia group were higher than those in control group,the differences were statistically significant(P＜0.05).The distribution of genotypes was in Hardy-Weinberg equilibrium(P＞0.05).The frequency of haptoglobin 2-2 genotype and haptoglobin 2 allele in vascular dementia group were higher than those in control group,and the differences were statistically significant(P＜0.05).There were significant differences in the scores of mini-mental state examination and hachinski ischaemic score among patients with vascular dementia with different haptoglobin genotypes(P＜0.05).Multivariate Logistic regression analysis showed that the carrier of hapto-globin 2-2 genotype and the carrier of haptoglobin 2 allele were independent risk factors for vascular dementia(P＜0.05).Conclusion Haptoglobin 2-2 genotype and haptoglobin 2 allele distribution frequency are associ-ated with the occurrence of vascular dementia after stroke,and those with high frequency of haptoglobin 2-2 genotype and haptoglobin 2 allele distribution suffer a severe disease,which can provide reference for early i-dentification and assessment of vascular dementia.
