ObjectiveThis paper used the AGREE Ⅱ guideline evaluation tool to evaluate the quality of 14 clinical guidelines for acute myocardial infarction，aiming to provide reference for the formulation and improvement of the guidelines. MethodsClinical guidelines and expert consensus related to acute myocardial infarction were searched by web search. The search period ranges from January 1，2019 to November 1，2024 in CNKI，VIP，Wanfang Data，SinoMed，Web of Science，OVID， the International Guidelines Collaboration Network （GIN），the UK National Institute for Health and Clinical Excellence （NICE），Yimaitong， and other platforms. Three researchers independently screened the literature and used AGREE Ⅱ to score the screening results. After ensuring that the researchers have a consistent understanding of each guideline，the quality of the guidelines was evaluated. After that，the ratings were analyzed by layer according to the issuing agency，category，method of formulation，and funding situation and compared longitudinally by rating time. The clinical guidelines and expert consensus were compared in terms of content and evidence. ResultsA total of 14 guidelines and consensus were included. The results of AGREE Ⅱ in the six areas in descending order were scope and purpose （62.82%±10.43%），rigor （62.40%±12.77%），editorial independence （62.11%±22.26%），participants （61.42%±11.65%），clarity of expression （59.98%±9.62%），and application （52.94%±16.90%） . Eleven of the guidelines were at level B， and three were at level A. In the stratified analysis，the score of the guideline formulated by the Chinese Medical Doctor Association was lower. There was little difference between the scores of Chinese/Western and Western medicine guidelines. The average score of the guidelines was higher than the consensus. Funded guidelines and consensus scores were higher. In the longitudinal comparison，the highest number of guidelines were developed in 2020 and 2021，while those developed in 2023 scored the highest. In the differential comparison analysis，the content of the guidelines was more comprehensive， and the evidence level was higher，while the content of the consensus was more novel， and the evidence was less. ConclusionThe AGREE Ⅱ score of the clinical guidelines for acute myocardial infarction is generally moderate，and there is room for improvement in terms of applicability. At the same time，the content quality of expert consensus should be improved，and more efforts should be made to develop and apply Chinese medicine guidelines for complications such as heart failure and microcirculatory obstruction after acute myocardial infarction.

Progressive fibrosing interstitial lung disease （PF-ILD） has a complex etiology， and is classified as lung impediment stage， impediment-atrophy combination stage， and lung atrophy stage according to the different clinical manifestations during the progression of disease. Based on the theory of opening-closing-pivoting to analyse the characteristics of yin and yang disease mechanism and the idea of prescriptions in the three stages. For lung impediment stage， main as three-Yang fail to keep inside， disharmony between Ying qi （营气） and Wei qi （卫气）， shaoyin impairment， treatment should use Mahuang （Ephedra sinica） and Guizhi （Neolitsea cassia） flexibly to form a formula， or choose pungent-dispersing formulas like Baidu Powder （败毒散） to move qi and save yang， and diffuse and disperse impediment pathogen， meanwhile combining saving-shaoyin medicinals like Fuzi （Aconitum carmichaelii） and Shudihuang （Radix Rehmanniae Praeparata） to reinforce healthy qi and dispel pathogen； for impediment-atrophy combination stage， rooted as yangming impairment and progressed by over-movement of qi， treatment should use Mahuang Shengma Decoction （麻黄升麻汤） to resolve and decrease over-activities， emphasis on both opening and closing， and improve impediment and atrophy； for lung atrophy stage with three-Yin in a bad condition simultaneously and poor prognosis， treatment should use modified Jinshui Liujun Decoction （金水六君煎） to consolidate qi and save yin， disperse phlegm and stasis， to improve the quality of life for patients with PF-ILD.

In order to understand nurses’ willingness to participate in humanistic nursing training and its influencing factors, and provide reference for managers to understand the current situation and improve nurses’ enthusiasm for humanistic nursing training. The convenience sampling method was used to investigate 23 707 nurses in 28 provinces (autonomous regions and municipalities directly under the central government) through a self-designed questionnaire distributed on the Internet. The results showed that 98.1% of nurses thought that participating in humanistic nursing related training was helpful to clinical work, but only 88.6% of the respondents were willing to participate in humanistic nursing training. Thirty factors were analyzed from four aspects of basic characteristics of individuals, cognitive relevant experience and organizational atmosphere. Fifteen factors had significant significance in binary Logistic regression analysis (P<0.05). Among them, the factors that had a positive impact on training willingness were: marriage, education, professional title, post establishment, agree with humanistic care is the basic duty of a nurse praised, experience of being praised at work, family support, rapport with patients, passion of colleagues to participate in training, sustained high-quality care demonstration activities, join the humanistic care related organization, hospital reimbursement of training expenses (OR value of 6.559~1.113, P<0.001). The OR value of humanistic nursing as a nurse’s responsibility was 6.559 and the 95%CI was 5.585~7.702. The factors that hindered nurses from participating in training were: work occupied most of time and energy, think humanistic nursing is abstract and difficult to understand, think the mastered humanistic knowledge and skills meet the needs of work (OR value of 0.657~0.722, P<0.001). Through the analysis, it is considered that nurses have a extremely consistent high recognition of the significance of humanistic nursing training, but their willingness to receive training is affected by many factors such as individual experience, cognitive attitude and organizational atmosphere. In order to realize nurses’ high recognition of humanistic nursing training to high enthusiasm of behavior, the aspects of individual cognition and organizational atmosphere must be discussed.

Objective To analyze the research hotspots and development in the field of post-stroke pneumonia over the past decade. Methods The English literature on post-stroke pneumonia in the Web of Science Core Collection database from January,2014 to June,2024 was retrieved,and analyzed using CiteSpace 6.3.R1 software.

Conclusion The researches related to post-stroke pneumonia present an inverted U-shape in the past ten years.The rela-tionship and risk management of post-stroke pneumonia with dysphagia and venous thromboembolism are the main hotspots in the researches.The studies may tend to explore the sensitivity of the integration scale for post-stroke pneumonia and the control of risk factors during mechanical thrombectomy.

OBJECTIVE To investigate the impact of mercuric sulfide nanoparticles(HgS-NP)on various neurotransmitter-type neurons in Caenorhabditis elegans(C.elegans).METHODS Wild-type N2 C.elegans,as well as the transgenic C.elegans expressing green fluorescent protein specifically in gamma-amino-butyric acid(GABA)-ergic,glutamatergic,dopaminergic,cholinergic,and serotoninergic neurons(strains EG1285,DA1240,BZ555,LX929,and GR1366),were synchronized at the L4 stage and treated with different concentrations of HgS-NP via solid exposure.① Five transgenic strains of C.elegans were exposed to HgS-NP 0(control group),250,500,and 1000 mg·L-1 for 72 h.Fluorescence microscopy was used to observe the expression of green fluorescence in different neurotransmitter-type neurons of the corresponding transgenic C.elegans.② Wild-type N2 C.elegans were exposed to HgS-NP 0(control group)and 1000 mg·L-1 for 72 h.Real-time quantitative PCR(RT-qPCR)was performed to detect the mRNA expression levels of 33 genes related to the GABAergic and glutamatergic neurotransmitter systems.RESULTS ① Compared with the control group of the same genotype,the EG1285 C.elegans exhibited soma shrinkage,dendrite fragmentation,and neuronal loss,with a significant decrease in the relative fluorescence intensity of GABAergic neurons(P<0.05)after exposure to different concentra-tions of HgS-NP.After exposure to HgS-NP 1000 mg·L-1,the DA1240 C.elegans showed a loss of glutamatergic neurons in the head region and a significant decrease in the relative fluorescence intensity(P<0.01).However,there were no significant changes in the morphology or relative fluorescence intensity of dopaminergic,cholinergic,and serotoninergic neurons in BZ555,LX929,and GR1366 C.elegans after exposure to HgS-NP,respectively.② Compared with the control group,wild-type N2 C.elegans exposed to HgS-NP 1000 mg·L-1 showed increased mRNA expression levels of glr-7 and glr-8,which encoded non-N-methyl-D-aspartate glutamate receptors(P<0.05),while the expression levels of the remaining 31 genes related to the GABAergic and glutamatergic neurotransmitter systems showed no significant changes.CONCLUSION Exposure to a high dose of HgS-NP for 72 h may potentially damage the GABAergic and glutamatergic neurons in C.elegans,but have no significant effect on dopaminergic,cholinergic or serotoninergic neurons.

Objective To investigate the effect and mechanism of IL-17 on heart failure(HF)in hy-pertensive rats based on NF-κB/sarco-endoplasmic reticulum calcium ATPase 2(SERCA2)signa-ling pathway.Methods Thirty SPF male spontaneously hypertensive rats(SHR)aged 6-8 weeks were divided into control group,model group,phosphate buffer salt(PBS)solution injec-tion group(PBS group),IL-17 protein injection group(IL-17 group)and IL-17 and antibody injec-tion group(IL-17+IgG group),with 6 animals in each group.Hypertensive HF model was estab-lished,and corresponding agents were applied to the PBS group,IL-17 group and IL-17+IgG group intraperitoneally,respectively.The role of IL-17,NF-κB and SERCA2 in hypertensive HF was studied with HE staining,immunohistochemical assay,Western blotting,RT-qPCR and ELISA.Results Significantly higher serum levels of NT-proBNP and IL-17,enhanced myocardial expression of IL-17 mRNA and NF-κB protein,lower serum VEGF level,and down-regulated pro-tein level of SERCA2 in heart tissue were observed in the model group and the PBS group when compared with the control group(P＜0.01).The IL-17 group had obviously higher serum NT-proBNP and IL-17 levels and myocardial expression of IL-17 mRNA and NF-κB protein,and reduced serum VEGF level and SERCA2 protein level in heart tissue than the model group(P＜0.01).IL-17+IgG treatment resulted in notably lower serum IL-17 level and myocardial NF-κB protein level when compared with those of model group(8.98±1.20 vs 11.19±1.22,0.88±0.03 vs 0.93±0.03,P＜0.01),and also resulted in remarkably reduced serum levels of NT-proBNP and IL-17 and myocardial expression of IL-17 mRNA and NF-κB protein but increased serum VEGF level and SERCA2 protein level in heart tissue when compared with the IL-17 group(P＜0.01).The heart rate,SBP,IVSd,LVPWd,LVEDD and LVESD were significantly lower,while LVFS was notably higher in the IL-17+IgG group than the model group and IL-17 group(P＜0.01).The IL-17+IgG group had obviously higher LVEF than the IL-17 group[(70.81±6.50)％vs(62.77±5.43)％,P＜0.01].Conclusion IL-17/NF-κB/SERCA2 signaling pathway is involved in the regulation of inflammatory response after hypertensive HF,and inhibiting IL-17 can effective-ly improve the cardiac dysfunction caused by hypertensive HF.

ObjectiveTo analyze the microbial diversity in the rhizosphere soil of Gastrodia elata with different yields and explore the influence of soil microorganisms on the yield of G. elata. MethodThe experiment adopted the 16S DNA and ITS high-throughput sequencing technologies to study the diversity of the bacterial and fungal community in the rhizosphere soil of G. elata with high yield （GC） and low yield （DC）. ResultProteobacteria， Firmicutes， and other unidentified Bacteria were dominant in the rhizosphere soil of G. elata. The dominant rhizosphere fungi were Ascomycota， Basidiomycota， and Mortierellomycota. There was no significant difference in microbial community abundance in the high-yield and low-yield rhizosphere soil of G. elata， but there was a significant difference in species composition. Thirty-eight microbes such as Bradyrhizobium， Schleiferilactobacillus， and Archaeorhizomyces were gathered in large numbers in the high-yield rhizosphere soil， and thirty microbes such as Fusarium， Coprinellus， and Nitrosotalea were gathered in large numbers in the low-yield rhizosphere soil. At the level of genus and species， there were six different species in the high-yield and low-yield rhizosphere soil of G. elata， among which Russula mariae， Archeaeorhizomyces， and Ilyonectria were gathered in the high-yield rhizosphere soil of G. elata， while Nitrosotalea， Coprinellus disserminatus， and Fusarium were gathered in the low-yield rhizosphere soil of G. elata. ConclusionThere are different microorganisms in the rhizosphere soil of G. elata with different yields， and it is speculated that these microorganisms are related to the yields of G. elata. The research results are expected to provide a vital theoretical basis for the follow-up study of the high yield of G. elata.

ObjectiveTo review the drug information and research progress on oral Chinese patent medicines in the treatment of cardiac arrhythmia to identify existing problems and provide references for follow-up research. MethodChinese patent medicines against cardiac arrhythmia were retrieved from the three major drug catalogues，Yaozh.com，and relevant guidelines with arrhythmia as the retrieval term. The instructions for included Chinese patent medicines were retrieved through Yaozh.com and specific information was extracted. The research articles on Chinese patent medicines included were retrieved from the five databases，and the information meeting the inclusion and exclusion criteria was extracted and displayed in the form of text description and graphs after statistical analysis. ResultSixty-five oral Chinese patent medicines were included in this study，with the main functions of activating the blood and resolving stasis. The average daily cost of medicines was 8.17 yuan，and there were 42 medicines with an average daily cost of less than 10 yuan，showing a moderate medicine cost. A total of 351 research articles on Chinese patent medicines were screened out，including 259 randomized controlled trials （RCTs），16 non-RCTs，eight non-controlled trials，62 systematic reviews，two guidelines，and two expert consensuses. Eighteen types of Chinese patent medicines were involved，whose clinical trials had been conducted in 28 provinces，cities，autonomous regions，and municipalities in China. Wenxin granules and Shensong Yangxin capsules were the top medicines under investigation，accounting for 75.21% of all research articles. Among the included studies，the most common comparison design was Chinese patent medicine combined with western medicine vs western medicine （64.25%）. The outcome evaluation was mainly based on clinical efficacy，symptom efficacy，arrhythmia efficacy，adverse reactions，and heart rate changes. ConclusionThe number of clinical studies of oral Chinese patent medicines against cardiac arrhythmia varies greatly，but traditional Chinese medicine （TCM） syndrome differentiation thinking is less considered in practical application. Due to unstandardized clinical research and low-quality literature，further advancement is required in the future.
