OBJECTIVE To construct a pharmaceutical care framework suitable for elderly individuals in nursing homes， so as to provide standardized content guidance for relevant practice. METHODS The initial items of pharmaceutical care content in n ursing homes were drafted through literature research and semi-structured interviews. Delphi method was used to conduct correspondence consultation among 38 experts from related fields in Xinjiang. The expert positive coefficient， authority coefficient， and Kendall’s W were calculated， and the analytic hierarchy process was employed to determine the weight of each item. After thorough discussion among the research team members， the pharmaceutical care framework suitable for elderly individuals provided by hospital pharmacists collaborating with nursing homes was finalized. RESULTS The questionnaire recovery rates for both rounds of expert correspondence consultation were 100%， with an authority coefficient ＞0.8 and Kendall’s W ranging between 0.153 and 0.185 （ P ＜0.001）. A total of 7 primary items and 31 secondary items were ultimately determined， with the consistency ratio of the item weights all being less than 0.1. Based on the integration of importance and feasibility， among the primary items， “assessment of pharmaceutical care needs” was assigned the highest weight. Among the secondary items， highly practical items such as “survey of pharmaceutical care needs”“guidance on usage and dosage”“methods for correctly reading drug package inserts”， and “self-management of common chronic diseases in the elderly” were assigned relatively high comprehensive weights. CONCLUSIONS The pharmaceutical care framework suitable for elderly individuals provided by hospital pharmacists collaborating with nursing homes， which was constructed based on the Delphi method， demonstrates good scientific validity and reliability， and can serve as a reference for pharmacists to provide pharmaceutical care in nursing homes.

Objective: To discover molecular markers associated with lung adenocarcinoma diagnosis/prognosis and drug resistance through screening of differentially expressed genes based on published chip data in gene expression databases using bioinformatics methods. Methods: Comprehensive analysis was performed in available mRNA microarray datasets including lung adenocarcinoma tissues dataset GSE32863 and lung adenocarcinoma taxane-platin resistance dataset GSE77209 from the gene expression omnibus(GEO) database. Gene ontology enrichment analysis, gene pathway enrichment analysis and protein interaction network analysis were performed based on significantly correlated genes. The expression level of genes was validated in the cancer genome atlas(TCGA) dataset. Survival differences were assessed by the log-rank test in TCGA lung adenocarcinoma dataset. Based on the publications genomics of drug sensitivity in cancer(GDSC) database in CellMiner cross database(CellMiner CDB), Pearson correlation analysis was used to analyze the correlation between differentially expressed genes and the half-maximal inhibitory concentration(IC50) of anticancer drugs. Results : There were a total of 77 genes which had a different expression in resistance lung adenocarcinoma cells and lung adenocarcinoma cancer tissues. The functional enrichment analysis showed that these co-different expression genes were mainly enriched in microtubule, extracellular exosome, cell cycle and signaling by nuclear receptors. Protein-protein interactions(PPI) network screened 6 most connected genes as molecular complex(MCODE). Among the MCODE, overexpressed ubiquitin conjugating enzyme E2 T(UBE2T), kinesin family member 20A(KIF20A), PCNA clamp associated factor(KIAA0101), pituitary tumor-transforming gene 1(PTTG1) and NIMA related kinase 2(NEK2) were associated with poor outcomes. Survival analysis results showed that these five genes were upregulated in lung adenocarcinoma tissues and drug-resistant cells and were significantly associated with poor prognosis in lung adenocarcinoma patients. Drug sensitivity analysis results suggested that high expression of PTTG1 and UBE2T was significantly associated with sensitivity to multiple anticancer drugs, including paclitaxel and docetaxel. RT-PCR validation showed that PTTG1 andUBE2T were highly expressed in docetaxel-resistant cells A549-TXR and H358-TXR. Conclusion PTTG1 andUBE2T holds the potential to be chemoresistance markers in lung adenocarcinoma.

Objective : To explore the therapeutic effect of extracellular vesicles(EVs) of Aspergillus flavus(A. flavus) on A. flavus infection. Methods: The EVs of A. flavus were isolated using ultracentrifugation and detected/identified by nanoparticle tracking analysis(NTA). Quantitative real-time PCR(qRT-PCR) and enzyme-linked immunosorbent assay(ELISA) kits were used to assess the effect of A. flavus EVs on the polarization of bone marrowderived macrophages(BMDMs) and the expression levels of several cytokines,including tumor necrosis factor-α(TNF-α),interferon-γ(IFN-γ),interleukin-6(IL-6),and interleukin-10(IL-10). The Galleria mellonella(G.mellonella) infection model was constructed. Three concentration groups of A. flavus EVs(0. 2,2,and 20 μg/larvae) were set as the experimental groups,and PBS was used as the control group for the infection model.Meanwhile,three forms of negative control groups were established,including the PBS group,the pierced controlgroup, and the negative control group. The therapeutic effect of A. flavus EVs on A. flavus infection was evaluated by the survival rate of the G. mellonella infection models. Results: The particle size of A. flavus EVs ranged from 20 to550 nm. A. flavus EVs could polarize BMDMs into both M1 and M2 phenotypes and induce the production of cytokines,including TNF-α,IFN-γ,IL-6,and IL-10. The results of the G. mellonella infection model showed that A.flavus EVs could improve the survival rate of G. mellonella after A. flavus infection. Conclusion The EVs produced by A. flavus can promote the expression of both pro-inflammatory and anti-inflammatory cytokines in BMDMs,induce M1 polarization and M2 polarization of BMDMs,and increase the survival rate of G. mellonella after A. flavus infection.

BACKGROUND:Traditional surgery for lumbar disc herniation involves extensive excision of tissue surrounding the nerve for decompression and removal of protruding lumbar intervertebral discs,which poses various risks and complications such as nerve damage causing paralysis,lumbar instability,herniation recurrence,intervertebral space infection,and adjacent vertebral diseases. OBJECTIVE:To propose the symmetrically adduction of lumbar decompression induced resorption of herniated nucleus pulpous technique for lumbar spine symmetrically decompression,showing the induced resorption of herniated nucleus pulpous phenomenon and early clinical efficacy,and then analyze its decompression mechanism. METHODS:214 patients with lumbar disc herniation at Department of Orthopedics,First Affiliated Hospital of Zhengzhou University from March 2021 to May 2023 were enrolled in this study.Among them,81 patients received conservative treatment as the control group,and 133 patients received symmetrically adduction of lumbar decompression induced resorption of herniated nucleus pulpous treatment as the trial group.Before surgery,immediately after surgery(7-14 days),and early after surgery(over 1 year),MRI images were used to measure the volume changes of lumbar disc herniation.CT images were used to measure the posterior displacement distance of the lumbar spinous process ligament complex,as well as the width and height of the lateral recess.Japanese Orthopaedic Association scores were used to evaluate the patient's neurological function recovery. RESULTS AND CONCLUSION:(1)Control group:81 patients with lumbar disc herniation were treated conservatively,with a total of 171 herniated lumbar discs.The average follow-up time was(22.7±23.1)months.The first and second MRI measurements of 171 herniated lumbar discs showed herniated lumbar disc volumes of(551.6±257.9)mm3 and(792.2±330.4)mm3,respectively,with an average volume increase rate of(53.2±44.4)%,showing statistically significant differences(P<0.001).Out of 171 herniated lumbar discs,4 experienced natural shrinkage,with an absorption ratio of 2.3%(4/171)and an absorption rate of(24.5±9.9)%.(2)Trial group:133 patients with lumbar disc herniation had a total of 285 herniated lumbar discs.(1)Immediately after surgery:All patients were followed up immediately after surgery.229 out of 285 herniated lumbar discs experienced retraction,with an absorption ratio of 80.3%(229/285)and an average absorption rate of(21.5±20.9)%,with significant and complete absorption accounting for 6.5%.There were a total of 70 herniated lumbar discs in the upper lumbar spine,with an absorption ratio of 85.7%(60/70),an average absorption rate of(23.1±19.5)%,and a maximum absorption rate of 86.6%.There were 215 herniated lumbar discs in the lower lumbar spine,with an absorption ratio of 78.6%(169/215),an average absorption rate of(21.0±21.3)%,and a maximum absorption rate of 83.2%.Significant and complete absorption of the upper and lower lumbar vertebrae accounted for 5.7%and 6.5%,respectively,with no statistically significant difference(P>0.05).The average distance of posterior displacement of the spinous process ligament complex immediately after surgery was(5.2±2.8)mm.There were no significant differences in the width and height of the left and right lateral recess before and immediately after surgery(P>0.05).The Japanese Orthopaedic Association score immediately after surgery increased from(10.1±3.4)before surgery to(17.0±4.8),and the immediate effective rate after surgery reached 95.6%.(2)Early postoperative period:Among them,46 patients completed the early postoperative follow-up.There were 101 herniated lumbar discs,with an absorption ratio of 94%(95/101)and an average absorption rate of(36.9±23.7)%.Significant and complete absorption accounted for 30.6%,with a maximum absorption rate of 100%.Out of 101 herniated lumbar discs,3 remained unchanged in volume,with a volume invariance rate of 2.97%(3/101).Out of 101 herniated lumbar discs,3 had an increased volume of herniated lumbar discs,with an increase ratio of 2.97%(3/101)and an increase rate of(18.5±18.4)%.The Japanese Orthopaedic Association score increased from preoperative(9.3±5.1)to(23.5±4.0),with an excellent and good rate of 93.4%.(3)The early postoperative lumbar disc herniation absorption ratios of the control group and trial group were 2.3%and 85.9%,respectively,with statistically significant differences(P<0.001).(4)Complications:There were two cases of incision exudation and delayed healing in the trial group.After conservative treatment such as dressing change,no nerve injury or death occurred in the incision healing,and no cases underwent a second surgery.(5)It is concluded that symmetrically adduction of lumbar decompression induced resorption of herniated nucleus pulpous is a new method for treating lumbar disc herniation that can avoid extensive excision of the"ring"nerve and achieve satisfactory early clinical efficacy.It does not damage the lumbar facet joints or alter the basic anatomical structure of the lateral recess,fully preserves the herniated lumbar discs,and can induce significant or even complete induced resorption of herniated nucleus pulpous.Symmetrically adduction of lumbar decompression induced resorption of herniated nucleus pulpous provides a new basis and method for the clinical treatment of lumbar disc herniation.

Objective To establish and verify a mature and stable glioblastoma(GBM)organoid model,so as to provide an accurate and personalized preclinical model for the research and treatment of GBM.Methods Fresh GBM tissues obtained through surgical procedures were initially processed,and then GBM stem cells(GSCs)were isolated using stem cell culture medium and were identified.Subsequently,GSCs were cultured in organoid culture medium for 3D cultivation,and GBM organoids were successfully obtained.The histological morphology of GBM organoids was observed by hematoxylin-eosin(H-E)staining;the stemness and similarity to the parental tumor were identified by immunofluorescence staining;and the in vivo tumorigenic ability of GBM organoids was identified by orthotopic tumorigenesis experiments in nude mice.Results A total of 7 GBM organoids were constructed from 9 human GBM samples,with a morphology resembling"neurosphere",and the average duration for organoid formation was 1 week.H-E staining results showed that the histological morphology of GBM organoids under high-power microscope was very similar to that of GBM tumor tissues;immunofluorescence staining results indicated that the GBM organoids possessed stemness characteristics and histological cellular similarity;and GBM organoids had a stronger tumorigenic ability compared to ordinary GBM cells in nude mice.Conclusion This study presents a stable and reliable method for constructing GBM organoids retaining the histological characteristics of the original GBM tissue,which providing new insights for future GBM research and clinical practice.

Abdominal aortic aneurysm(AAA)is a degenerative vascular disease occurring in the lower segment of the aortic diaphragm,mainly manifested by irreversible dilatation of the entire artery,preferably in the elderly population.The pathogenesis of AAA is complex and involves multiple factors,with genetic variations and immune imbalances playing important roles.Its pathological changes mainly include inflammatory cell infiltration,degradation of stromal elastin,and smooth muscle cell death.Rupture of AAA is the most dangerous complication,with a high mortality.Surgery remains the only effective intervention,but carries certain risks and postoperative complications.Early intervention for small abdominal aortic aneurysms to slow down aneurysm expansion and achieve long-term survival is currently a focus of drug and technology research.This article reviews the pathogenesis of AAA and its intervention strategies,and summarizes the research on existing drugs and the use of new targets and technologies,so as to provide insights for better understanding and treatment of AAA.

Fusarium head blight (FHB), caused by Fusarium graminearum, not only leads to severe yield losses but also poses a threat to food safety due to the mycotoxins produced by the pathogen. Since this disease is preventable but not curable, the current control mainly relies on chemical fungicides, the long-term use of which may lead to pathogen resistance and environmental pollution. To develop green control methods, we screened 13 biocontrol strains from the rhizosphere soil of wheat, among which strain No. 12 (identified as Pythium aphanidermatum) showed significant antifungal effects. In the plate confrontation test, this strain reduced the colony diameter of the pathogen by 69.2% (1.47 mm vs. 4.78 mm in the control group), with an inhibition rate of 77% (P < 0.01). Microscopic observation revealed obvious deformations in the pathogen hyphae, suggesting a lysing effect. The coleoptile experiment further confirmed that the pre-treatment with this strain reduced the incidence rate to 0. These findings provide new candidate strains for the biocontrol of FHB and offer a scientific basis for reducing the use of chemical fungicides and promoting sustainable agricultural development.

Allergic rhinitis (AR), a globally prevalent immune-mediated inflammatory condition, is still an incurable disease. In the present study, we have validated the impact of the Kelch-like ECH associated protein 1 (Keap1)-related oxidative stress and inflammatory response in clinical AR patient peripheral blood and nasal swab samples, emphasizing the biological relevance of Keap1 and AR. Targeting Keap1 -nuclear factor erythroid 2-related factor 2 (Nrf2) related anti-oxidative stress may be effective for AR intervention. Drawing inspiration from the Keap1 homodimerization and the E3 ligase characteristics, we herein present a design of novel bivalent molecules for chemical knockdown of Keap1. For the first time, we characterized ternary complexes of Keap1 dimer and one molecule of bivalent compounds. The best bivalent molecule 8 encompasses robust capacity to degrade Keap1 as a homoPROTAC^KEAP1. It efficaciously suppresses inflammatory cytokines in extensively different cells, including human nasal epithelial cells. Moreover, in an AR mouse model, we confirmed that the chemical degradation induced by homoPROTAC^KEAP1 led to therapeutic benefits in managing AR symptoms, oxidative stress and inflammation. In summary, our findings underscore the efficacy of targeting the Keap1 system through the homoPROTAC-ing technology as an innovative and promising treatment strategy for the incurable allergic disorders.

Objective:To propose policy recommendations for the compensation mechanism of high-quality development of municipal public hospitals.Methods:Taking the municipal public hospitals in Shanghai as the research object,the aspects of financial subsidies,the structure of medical service income,investment in scientific research and education,and other social compensations were examined to conduct a systematic simulation of the operation of the average municipal public hospital in Shanghai under different policy intervention scenarios.Results:If the current conditions remain unchanged,the average municipal public hospital in Shanghai will face a deficit starting in 2032,the proportion of income from examinations and laboratory tests will surpass that of medical service income in 2026 and 2031,respectively.If the hospitals follow a plan of Combination Plan 3,4,and 5,the average municipal public hospital in Shanghai will be able to break even from 2023 to 2033,and the structure of medical service income will be significantly optimized.Conclusion:To establish a new compensation mechanism for high-quality hospital development that enhances medical services,it is recommended to optimize the structure of government financial compensation,explore rational pricing strategies based on categories,increase investment in scientific research and education while paying attention to the transformation of scientific and technological achievements,expand compensation channels for public hospitals,and improve relevant laws and regulations.

Objective To investigate the anatomical structure and surface location of the Lieque(LU7)acupoint.Methods Firstly,the anatomical localization descriptions of the Lieque(LU7)acupoint from classical medical literature were reviewed and summarized.A total of 21 participants were recruited from Shandong Provincial Hospital Affiliated to Shandong First Medical University from January to March 2025.A Cartesian coordinate system was established over the Lieque(LU7)region on the right forearm.Following standardized manual pressure stimulation,the coordinates of the participant′s reported acupoint sensations were recorded.Based on surface pressure mapping result,10 participants were arbitrarily selected for acupuncture intervention.Upon elicitation of acupoint sensation,the ultrasound imaging was used for real-time visualization of anatomical spatial relationships between the needle tip and distal radial osseous landmarks.Five red latex-perfused adult upper limb specimens were selected for microdissection of the Lieque(LU7)regions pre-localized via ultrasonography,achieving definitive structural characterization of its anatomical strata.Another 10 participants were arbitrarily selected to find the physical structure of the Lieque(LU7)acupoint using ultrasound,and the similarities and differences of acupoint sensation responses were verified using acupuncture needle insertions into both the demarcated zone and peripheral tissues.Results The descriptions of the localization of the Lieque(LU7)acupoint in ancient books can be summarized as"one and a half cun above the wrist side"longitudinally,and"at the intersection head,between two tendons and two bones in the hollow"transversely.During surface pressure application,the sites of the participant′s elicited acupoint sensation were anatomically concentrated in the proximal depression adjacent to the radiopalmar ridge,specifically at the transitional interface between the extensor pollicis brevis tendon and scaphoid bone.During acupuncture-induced acupoint sensation,ultrasound imaging demonstrated that the location of the needle tip was located within the proximal depression adjacent to the radiopalmar ridge,accompanied by arterial hemodynamic perfusion signals into adjacent osseous interfaces.Microdissection findings revealed perforating branches of the radial artery traversing the cortical bone interface within the Lieque(LU7)acupoint region.Acupuncture stimulation at the proximal depression adjacent to the radiopalmar ridge elicited consistent acupoint sensations in all 10 participants,and the acupoint sensations differed from those of other surrounding tissues.Conclusion The anatomical structure of Lieque(LU7)acupoint is located within the proximal depression adjacent to the radiopalmar ridge,characterized by the presence of"hilus of bone"structure.
