OBJECTIVE To establish a Chinese drug-related problem （DRP） classification system applicable to pharmacist-led pharmaceutical care in China， providing pharmacists with an effective and practical tool for pharmaceutical care. METHODS A multi-stage process was employed to construct the DRP classification system， including literature review and analysis， comparison of existing classification systems， refinement of classification items and framework development， two rounds of standard case validation， expert discussion， and system revision. The Fleiss′ kappa test was used to calculate the consistency coefficient κ， assessing the reliability of pharmacists participating in evaluating the classification system. An electronic questionnaire comprising six items was employed to evaluate the system’s applicability. RESULTS The constructed Chinese DRP classification system comprised six sections [problem（including potential problems）， DRP evaluation， cause （including possible causes of potential problems）， intervention， acceptance of intervention and DRP status]， with 24 primary codes and 96 secondary codes. In the first round of case validation， κ values exceeded 0.4 for all sections except “intervention” and “DRP status”. In the second round， κ values exceeded 0.4 for all sections. In the applicability evaluation of the classification system， positive ratings （“strongly agree” or “agree”） exceeded 85% for all items. Specifically， positive ratings for“the classification system can provide appropriate category selection”，“ the classification system is comprehensive”，“ the classification system is convenient to use” and “the classification system is highly satisfactory” exceeded 92%. CONCLUSIONS The Chinese DRP classification system developed demonstrates both high reliability and applicability， providing an effective and practical classification tool for pharmacists in China to conduct pharmaceutical care.

Attention deficit and hyperactive disorder （ADHD） is the most common neurodevelopmental disorder of childhood. It seriously impairs academic achievement， social interaction， and vocational development， and increases the risk of accidental injury and substance abuse. In some cases， the symptoms may also exert an indirect disruptive effect on public order. Its aetiology involves interactions among genetic， perinatal environmental， and psychosocial factors that cannot be fully disentangled by single clinical studies. Therefore， a systematic evaluation of existing animal models is essential for revealing pathophysiology and developing novel therapies. Using the keywords "attention deficit and hyperactive disorder"， "models， animal"， "validity"， and their English equivalents， we systematically searched PubMed， Web of Science， CNKI， and Wanfang for publications from 2000 to 2025 （retrieving 328 publications） and added further references by citation tracking. Eighty-six rodent ADHD models that provided detailed construction protocols， behavioural assessments， neurobiological mechanisms， or pharmacological data were included and classified into spontaneous genetic， genetically engineered， and environmentally induced paradigms. Their face， construct， and predictive validity were compared. Among spontaneous genetic models， spontaneously hypertensive rats reproduce hyperactivity， impulsivity， and stimulant responses well， yet hypertension and sex differences limit specificity. Acallosal mouse strains link corpus callosum absence to ADHD-like behaviours， but neurotransmitter studies remain scarce. Genetically engineered rodents—including dopamine transporter， neurokinin-1 receptor and mediator complex subunit 23 knockout or conditional gene knockout lines—precisely dissect dopaminergic， noradrenergic， synaptic， or epigenetic pathways， yet generally lack full phenotypic coverage， social-deficit modelling， and comorbidity representation， and are accompanied by adverse effects such as growth retardation or ocular defects. Environmentally induced models employ lead， polychlorinated biphenyls， alcohol， nicotine exposures， 6-hydroxydopamine lesions， neonatal hypoxia， early social isolation， or maternal stress to recapitulate core symptoms. However， dose-schedule standardisation is lacking. Behavioural reversibility diverges from clinical persistence， and non-specific phenotypes such as anxiety or depression are common. Overall， no single paradigm simultaneously achieves high validity across all three dimensions. Currently， ADHD models have progressed from single-factor simulations to multidimensional evaluation， yet significant gaps remain in genetic-background standardisation， sex differences， cross-species translation， and syndrome-differentiation modelling under traditional Chinese medicine. Future directions should integrate genetic， environmental， and epigenetic interactions， establish life-span validation systems， and incorporate computational neuroscience alongside integrative Chinese-Western strategies to enhance clinical relevance and translational utility， thereby providing robust evidence-based support for mechanistic elucidation， drug screening and precision intervention in ADHD.

Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.

Sympathectomy, as an emerging treatment method for cardiovascular diseases, has received extensive attention in recent years. Stereotactic radiotherapy (SRT), a precise and noninvasive therapeutic technique, has gradually been introduced into interventions targeting the sympathetic nervous system and has shown promising prospects in the management of cardiovascular conditions. Using three-dimensional imaging, SRT can accurately localize sympathetic ganglia and deliver high-energy radiation to disrupt nerve fibers, thereby achieving effects similar to conventional sympathectomy while reducing surgery-related complications and shortening recovery time. It also offers the advantages of being noninvasive and causing fewer adverse effects, and thus holds potential as an alternative to traditional approaches in the future. The integration of SRT with sympathectomy opens new avenues for the treatment of cardiovascular diseases and presents broad clinical application prospects.

Objective To comparatively evaluate the diagnostic value of metagenomic next-generation sequencing(mNGS)versus conventional microbial culture in spinal infections.Methods A cross-section design was conducted on 82 consecutive patients with suspected spinal infections treated between February 2022 and January 2024 at Jiangbei Branch of First Affiliated Hospital of Army Medical University(Third Military Medical University).Microbiological culture,histopathological examination,and mNGS results from infected specimens were analyzed.Clinical diagnosis,primarily based on clinical manifestations,laboratory tests and radiologic features combined with medical history,was defined as the gold standard,and then the diagnostic performance,including sensitivity and specificity,were compared between mNGS and microbial culture.Results Among the 82 patients,definitive microbiological evidence was identified in 70 cases,and mNGS demonstrated a significantly higher detection rate than microbial culture(64 vs 36 cases,78.05％vs 43.9％,P<0.05).mNGS also obtained obviously higher sensitivity,accuracy,and negative predictive value(NPV),and notably lower positive predictive value(PPV)when compared to conventional microbial culture(all P<0.05).When stratified by infection type,mNGS obtained significantly higher sensitivity and accuracy compared to microbial culture in tuberculous spinal infections(P<0.05).For non-tuberculous spinal infections,mNGS also showed superior sensitivity to microbial culture(P<0.05).Conclusion In patients with spinal infections,mNGS demonstrates a significantly higher pathogen detection rate than conventional microbial culture.This technique can provide early and broad-spectrum pathogenic microbiological evidence for spinal infection.

Liquiritigenin(LG)is a flavone of pharmacological importance,however,its application potential is severely limited due to its poor water solubility.LG could be disassociated slightly in water to form phenolate anion,therefore,better solubilization effect is expected by inclusion with cationic cyclodextrins(CCDs).In this work,four kinds of CCDs modified with amino groups at the primary face were synthesized,and their solid inclusion complexes with LG were successfully prepared by preparing their saturated solutions.The formation of the solid inclusion complexes was confirmed by scanning electron microscopy(SEM)and powder X-ray diffraction(PXRD),and their supramolecular binding behavior in solution was studied using multiple techniques.A 1∶1 inclusion stoichiometry of inclusion complexation was defined using Job plot by ultraviolet-visible(UV-vis)spectroscopy,and their binding stability constants(Ks)were determined as 2862.77,3494.70,6521.85 and 9599.48 L/mol using UV-vis spectroscopic titration,far more superior to that of nativeβ-CD(Ks=236.79 L/mol).This indicated that the amino side chains on CCDs could actively participate in the inclusion complexation through anion-cation interactions,significantly strengthening the host-guest binding between CCDs and LG.The inclusion modes were further elucidated based on proton and two-dimensional rotating-frame overhauser enhancement spectroscopy(2D-ROESY)nuclear magnetic resonance(NMR)experiments and molecular docking.Water solubility of LG was dramatically promoted up to 4.9 mg/mL,which was 70-fold higher than that of native LG.This study could draw inspiration for the binding and solubilization of phenols such as flavones by design of cationic macrocyclic molecules.

Objective:To investigate the expression of Artemin (ARTN) in malignant peripheral nerve sheath tumor (MPNST), its effect on the malignant behavior of MPNST cells, and its signaling pathway.Methods:Fifty-one MPNST paraffin embedded tissues through surgical resection at Tianjin Medical University Cancer Hospital from January 1995 to November 2011 were collected, the expression of the ARTN protein was detected by immunohistochemistry, and the relationship between the ARTN protein expression and the clinical pathological characteristics and prognosis were analyzed. In human MPNST cell lines ST-8814 (NF-1) and STS26T(sporadic), ARTN overexpression and low expression cell lines were constructed by transfecting ARTN overexpression plasmids and ARTN small interfering RNA (siRNA), respectively. The expression of ARTN mRNA was detected by real time quantitative polymerase chain reaction (RT-qPCR), the expression of the ARTN protein and Phosphoinositide 3-kinase(PI3K)/Akt signaling pathway related proteins were detected by Western blot. CCK-8 assay was used to detect cell proliferation ability, and cell invasion assay was used to detect cell invasion ability. The pathway proteins that interacted with ARTN were searched in the STRING database, and the functional pathways were clarified by Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analysis. The PI3K/Akt pathway specific inhibitor LY294002 was used to block the PI3K/Akt pathway of ST-8814 and STS26T cells to observe the changes in cell proliferation and invasion.Results:Among the 51 MPNST tissue specimens, 22 cases showed a high expression of the ARTN protein and 29 cases showed a low expression of the protein. Higher expressions of the ARTN protein was associated with larger tumor diameters and disease progression (recurrence or metastasis) (both P＜0.05). The median disease-free survival (DFS) of patients with a low expression of the ARTN protein was 26.2 months, and the median overall survival (OS) was 66.9 months. The median DFS and median OS of patients with a high expression of the ARTN protein were 10.7 months and 53.8 months, respectively. The log rank test results showed that the progression free survival rate of patients with a high expression of the ARTN protein was worse than that of patients with a low expression ( P=0.027), but the difference in overall survival rate between the two groups was not statistically significant ( P=0.790), which was also confirmed by Cox regression analysis. The CCK-8 assay results showed that after 48 hours of transfection, the absorbance ( A) values of ST-8814 and STS26T cells in the ARTN overexpression group were 1.35±0.01 and 1.10±0.02, respectively, which were higher than those in the empty plasmid control group (1.05±0.01 and 0.78±0.01, both P＜0.01), while the A values of ST-8814 and STS26T cells in the ARTN siRNA group were 0.35±0.01 and 0.61±0.01, respectively, which were lower than those in the control siRNA group (0.74±0.01 and 1.10±0.04, both P＜0.01). The results of cell invasion assay showed that the number of transmembrane cells in ST-8814 and STS26T cells overexpressing ARTN was (29.67±2.08) and (31.67±2.08), respectively, which were higher than those in the empty plasmid control group [(20.00±1.00) and (24.33±1.15), both P＜0.01]. The number of transmembrane cells in ST-8814 and STS26T cells in the ARTN siRNA group were (14.00±2.00) and (19.33±1.53), respectively, which were lower than those in the control siRNA group [(19.33±2.52) and (23.33±0.58), both P＜0.05].The KEGG results showed that ARTN is associated with multiple tumor signaling pathways, especially the PI3K/Akt signaling pathway. Western blot results showed that overexpression of ARTN upregulated the expression of p-PI3K and p-Akt proteins in ST-8814 and STS26T cells (both P＜0.01).After knocking down ARTN expression, the expression of p-PI3K and p-Akt proteins was significantly down regulated (both P＜0.01). LY294002 could significantly inhibit the effect of ARTN overexpression on ST-8814 and STS26T cells after blocking the PI3K/Akt pathway. The A values of ST-8814 and STS26T cells in the ARTN overexpression+LY294002 group were 1.09±0.06 and 0.82±0.01, respectively, which were lower than those in the ARTN overexpression group (1.50±0.01 and 1.29±0.01, respectively, both P＜0.01). The numbers of transmembrane cells in the cell invasion assay were 16.67±3.21 and 19.67±2.31, respectively, which were also lower than those in the ARTN overexpression group (29.67±2.08 and 31.67±2.08, respectively, both P＜0.01). Conclusions:In MPNST, a high expression of the ARTN protein was associated with larger tumor size, disease progression, and worse DFS. ARTN promotes the proliferation and invasion of MPNST cells through the PI3K/Akt signaling pathway.

Objective:To investigate the clinical application of ultrasound-guided cervical plexus block combined with superior laryngeal nerve block in tracheotomy for burn patients.Methods:A total of 88 burn patients who underwent tracheotomy from January 2022 to December 2022 were divided into observation group(44 cases)and matched group(44 cases).The matched group received conventional general anesthesia,while the observation group underwent ultrasound-guided cervical plexus block combined with superior laryngeal nerve block.The operation time,anesthetic effect,intraoperative hemodynamic parameters,postoperative complications,and patient satisfaction were compared.Results:The surgery time in the observation group was shorter than that in the matched group(P＜0.05).The anesthetic effect in the observation group was superior to that in the matched group,with more stable intraoperative hemodynamics,and smaller fluctuations in heart rate and mean arterial pressure(P＜0.05).The incidence of postoperative cough reflex,hoarseness,postoperative pain score,and respiratory complications in the observation group were lower than those in the matched group(P＜0.05).Patient satisfaction in the observation group was higher than that in the matched group(P＜0.05).Conclusion:Ultrasound-guided cervical plexus block combined with superior laryngeal nerve block for tracheotomy in burn patients can effectively improve anesthetic effect,reduce operation time,stabilize intraoperative hemodynamics,reduce postoperative complications,and improve patient satisfaction,which is worthy of clinical application.

The structure and potential antigenic epitopes of FliCEcN were analysed using bioinformat-ics technology.With the help of ClonExpress? homologous recombination technology,primers were designed to deletion of different structural domains in the highly variable region of FliCEcN and cloned into pET-28a(+)expression vector for expression.The expressed flagellin variants were identified by SDS-PAGE and Western blot.Endotoxin residues in the flagellin variants were detected by horseshoe crab reagent chromatography,and Caco-2 cells were stimulated with differ-ent concentrations of flagellin variants.The biological activity of each flagellin variant was assessed by detecting the secretion level of IL-8.Bioinformatic analysis showed that most of the structural domains in the highly variable region of FliCEcN were predicted to contain potential antigenic epitopes.PC R results showed that fliC△820-1 518,fliC△736-963,fliC△985-1 200,fliC △748-828,fliC△1 114-1 191,andfliC△1 225-1311 were approximately 1 095,1 566,1 578,1 713,1 716 and 1 707 bp,respectively.SDS-PAGE results showed that the sizes of the flagellin variants treated with nickel column purifi-cation and dialysis replication were about 41.36,57.06,57.50,61.97,61.95 and 61.56 kDa,respec-tively.Western blot results showed that all six flagellin variants reacted specifically with anti-His monoclonal antibody and E.coli H7 antigen diagnostic serum.The results of TLR5 activity assay showed that the flagellin variants missing different structural domains retained their TLR5 agonist function.In this study,six flagellin variants with different structural domains of FliCEcN deletion hypervariable region were successfully constructed,and all of them retained their TLR5 agonist function and showed good biological properties.This provides a reference for further research on the adjuvant effect of flagellin after deletion of different structural domains and the effect of flagel-lin antibody titer on its adjuvant effect.
