Plant-derived exosome-like nanovesicles (PELNs), characterized by a natural lipid bilayer membrane, have rapidly emerged as a prominent research frontier in medicine owing to their unique biological properties and robust therapeutic potential. This review comprehensively examines the biological profiles, mechanistic functions, and recent engineering advancements of PELNs. In terms of composition, PELNs are uniquely enriched in plant-specific glycolipids, phosphatidylserine, secondary metabolites, and highly stable 2'-O-methylated miRNAs. This distinct molecular makeup endows them with exceptional biocompatibility, negligible immunogenicity, and the capacity for cross-species molecular communication. Mechanistically, PELNs demonstrate profound anti-inflammatory efficacy by suppressing the NF-κB and NLRP3 inflammasome pathways. They also serve as potent immune modulators, driving macrophage M1/M2 polarization and regulating T cell activity. Additionally, PELNs exhibit promising antitumor capabilities, targeting malignancies via reactive oxygen species (ROS) induction, TRAIL pathway activation, and tumor microenvironment remodeling. Crucially, the plant miRNAs encapsulated within PELNs remain highly stable in the gastrointestinal tract, allowing them to selectively alter gene expression in specific gut microbiota communities. This interaction deeply influences host immunity and metabolism, highlighting the vital role in cross-species regulation. Advancements in bioengineering have further expanded the clinical utility of PELNs. Targeted delivery efficiency can be significantly amplified via surface functionalization (e.g., folate and RGD sequences) and state-of-the-art drug loading technologies such as sonication and electroporation. Consequently, engineered PELNs surpass traditional synthetic nanocarriers in penetrating natural physiological barriers, particularly for oral and transdermal drug administration. Despite these advantages, clinical translation is currently hindered by the lack of standardized isolation protocols, challenges in scalable manufacturing, and the need for robust quality control frameworks. Looking forward, the integration of multi-omics approaches and AI-driven “molecular fingerprinting”—coupled with the design of synthetic biomimetic vesicles—will be instrumental in overcoming these bottlenecks, ultimately establishing PELNs as a next-generation platform for precision medicine and targeted nanotherapeutic delivery.

Hyperthermic intrathoracic chemotherapy (HITHOC) is a localized treatment that combines hyperthermia with medications such as chemotherapy, anti-angiogenic agents, targeted therapy, or immunotherapeutic agents. It has advanced clinical progress for conditions such as malignant pleural mesothelioma, pleural metastasis of lung cancer, and pleural dissemination of thymic tumors. Systematic analyses indicate that as an adjuvant therapy to cytoreductive surgery, HITHOC improves patient survival and effectively controls pleural effusion and pleural metastasis. It exerts antitumor effects by enhancing drug penetration through thermal effects, inducing apoptosis, and modulating the immune microenvironment. HITHOC combined with systemic therapies (e.g., chemotherapy, targeted therapy, and immunotherapy) demonstrates synergistic potential, but its role as a local treatment should be clearly defined as adjunctive within the comprehensive management of advanced-stage patients. Further research is needed to clarify its indications, standardized protocols, and long-term efficacy and to explore optimized regimens and personalized combination treatment strategies. This review delves into the key bottlenecks hindering the development of hyperthermia therapy, such as the lack of high-level evidence-based medicine and the absence of standardized diagnostic and efficacy evaluation criteria, and proposes potential solutions.

Sigma-1 receptor (σ ₁R) has become a focus point of drug discovery for central nervous system (CNS) diseases. A series of novel 1-phenylethan-1-one O-(2-aminoethyl) oxime derivatives were synthesized. In vitro biological evaluation led to the identification of 1a, 14a, 15d and 16d as the most high-affinity (K _i < 4 nmol/L) and selective σ ₁R agonists. Among these, 15d, the most metabolically stable derivative exhibited high selectivity for σ ₁R in relation to σ ₂R and 52 other human targets. In addition to low CYP450 inhibition and induction, 15d also exhibited high brain permeability and excellent oral bioavailability. Importantly, 15d demonstrated effective antipsychotic potency, particularly for alleviating negative symptoms and improving cognitive impairment in experimental animal models, both of which are major challenges for schizophrenia treatment. Moreover, 15d produced no significant extrapyramidal symptoms, exhibiting superior pharmacological profiles in relation to current antipsychotic drugs. Mechanistically, 15d inhibited GSK3β and enhanced prefrontal BDNF expression and excitatory synaptic transmission in pyramidal neurons. Collectively, these in vivo proof-of-concept findings provide substantial experimental evidence to demonstrate that modulating σ ₁R represents a potential new therapeutic approach for schizophrenia. The novel chemical entity along with its favorable drug-like and pharmacological profile of 15d renders it a promising candidate for treating schizophrenia.

Digital technologies have become an integral part of complete denture restoration. With advancement in computer-aided design and computer-aided manufacturing (CAD/CAM), tools such as intraoral scanning, facial scanning, 3D printing, and numerical control machining are reshaping the workflow of complete denture restoration. Unlike conventional methods that rely heavily on clinical experience and manual techniques, digital technologies offer greater precision, predictability, and efficacy. They also streamline the process by reducing the number of patient visits and improving overall comfort. Despite these improvements, the clinical application of digital complete denture restoration still faces challenges that require further standardization. The major issues include appropriate case selection, establishing consistent digital workflows, and evaluating long-term outcomes. To address these challenges and provide clinical guidance for practitioners, this expert consensus outlines the principles, advantages, and limitations of digital complete denture technology. The aim of this review was to offer practical recommendations on indications, clinical procedures and precautions, evaluation metrics, and outcome assessment to support digital restoration of complete denture in clinical practice.

The single photon counting imaging detector based on microchannel plate(MCP)has the characteristics of high sensitivity and low dark count rate,and has been applied to the optical remote sensing detection of weak ultraviolet spectral signals in space.In this work,by using planar array single photon counting imaging detector as the detector,flat-field concave grating as the splitter,and electrodeless discharge lamp(EDL)as the excitation light source,a dispersion detection system suitable for hydride generation-atomic fluorescence spectrometry(HG-AFS)was developed.The wavelength calibration of the system was carried out,and the negative high pressure and EDL stability time of the planar array single photon counting imaging detector were analyzed and optimized.The characteristic emission spectral lines of As and Bi elements excited in the wavelength range of 180-320 nm were analyzed,and the scattering interference in the wavelength range of 257.3-306.7 nm was discussed.The results showed that the AFS dispersion detection system based on the planar array single photon counting imaging detector could detect and analyze the HG-AFS fluorescence signal initially,and the influence of scattering interference on the detection results was effectively avoided.The system had the advantages including simple structure,no refrigeration and temperature control,no moving parts and simultaneous measurement of multi-band.

Objective To investigate the relationship between serum small dense low density lipoprotein cholesterol(sdLDL-C),systemic inflammatory response index(SIRI),monocyte to high density lipoprotein cholesterol ratio(MHR)and coronary artery injury(CAL)and intravenous immunoglobulin(IVIG)treat-ment response in Kawasaki disease(KD)children.Methods From April 2021 to December 2023,121 KD children(KD group)admitted to our hospital were divided into CAL group(42 cases)and NCAL group(79 cases)according to whether CAL occurred.Another 121 healthy children who underwent physical examina-tions in the hospital during the same period were selected as the control group.All the children in the KD group received IVIG treatment and were divided into the IVIG response group(99 cases)and the IVIG non-response group(22 cases)according to the treatment response.The differences in serum sdLDLC,SIRI and MHR levels among each group were compared.Univariate and multivariate Logistic regression models were used to analyze the factors influencing the non-response of children with KD to IVIG treatment,and the re-ceiver operating characteristic(ROC)curve was used to analyze the value of serum sdLDL-C,SIRI,and MHR in predicting the non-response of children with KD to IVIG treatment.Results Serum levels of sdLDL-C,SI-RI and MHR in the KD group were higher than those in the control group(P＜0.05).Serum levels of sdLDL-C,SIRI and MHR in the CAL group were higher than those in the NCAL group(P＜0.05).Serum levels of sdLDL-C,SIRI and MHR in the IVIG non-response group were higher than those in the IVIG response group(P＜0.05).The fever duration in the IVIG non-response group was longer than that in the IVIG response group(P＜0.05),and the combined proportion of CAL,the proportion of neutrophils,white blood cell count,C-reactive protein(CRP),interleukin-6(IL-6),erythrocyte sedimentation rate,and ferritin level were higher than those in the IVIG response group(P＜0.05).High CRP level,high sdLDL-C level,high SIRI and high MHR were risk factors for response to IVIG treatment in children with KD(P＜0.05).The areas under the curve(AUC)of serum sdLDL-C,SIRI,and MHR for predicting response to IVIG treatment in children with KD were 0.773,0.767,and 0.780 respectively.The combined prediction AUC was 0.948,which was higher than the individual predictions of each index.Conclusion The abnormal increase of serum sdLDL-C,SIRI and MHR in KD children is related to the occurrence of non-response to CAL and IVIG treatment.The combina-tion of the three can effectively predict the response to IVIG treatment.

Objective:To evaluate the efficacy and feasibility of a domestically developed robotic surgical system based on fiber-optic dedicated line communication in cross-regional urological telesurgery.Methods:This was multicenter，single-arm，retrospective case series study. The data of patients who underwent urological telesurgeries using the telesurgical system between January 2023 and December 2024 were analyzed. The cohort included 59 patients from seven hospitals across China. Among the patients，47 were male（79.7%）and 12 were female（20.3%），with a median age of 63.0（56.0，68.0）years and a body mass index of（24.7 ± 3.0）kg/m 2. Surgical procedures included 32 radical prostatectomies，24 partial nephrectomies，one radical nephrectomy，one adrenalectomy，and one ureteral reconstruction. The perioperative indicators，pathological results and postoperative complications were analyzed. The network monitoring data were collected，and the perioperative data of patients，remote system monitoring data and costs were compared between the two communication modes of optical transport network（OTN）and cloud-connect network（CCN）. Results:All 59 remote surgeries were successfully completed，with a mean operative time of（138.0 ± 54.0）minutes，median intraoperative blood loss of 50.0（30.0，100.0）ml and a postoperative hospital stay of 5.0（4.0，6.0）days. No cases required reoperation，Clavien-Dindo grade ≥3 complications，or readmission. The geographical distance between the primary and remote surgical sites ranged from 450 to 2 800 km. Network monitoring revealed increased bidirectional latency with distance increasing：the shortest latency time（Hefei-Hangzhou，450 km）was（16.59 ± 0.80）ms，while the longest（Harbin-Hangzhou，2 200 km）latency time was（53.31 ± 0.31）ms. Average frame loss per procedure was 0?1.27 frames. The results of subgroup analysis comparing OTN and CCN communication modes showed no significant differences in operative time［（130.7 ± 70.5）minutes vs.（142.1 ± 42.9）minutes， P = 0.442］，postoperative hospitalization［6.0（4.0，8.0）d vs. 5.0（4.0，6.0）d， P = 0.581］，or readmission rates（0 vs. 0）. However，CCN demonstrated significant cost advantages with 500 RMB per operation vs. 3 000 RMB per operation for OTN. Conclusions:Urological telesurgery using fiber-optic communication is feasible. The CCN mode，with its cost-effectiveness，excellent usability，and multi-point interconnection flexibility，is currently the preferred communication model for telesurgical applications.

Objective To develop a graded early mobility implementation pathway for critically ill adult patients in tertiary hospitals in Beijing and to preliminarily validate its feasibility and effectiveness.Methods Based on the"goal-directed"early mobility concept,a graded early mobility implementation pathway for critically ill patients was developed through evidence synthesis and the Delphi method,consisting of 3 components:patient inclusion,mobility implementation,and mobility evaluation.Using convenience sampling,patients meeting inclusion criteria in the general ICU of a tertiary hospital in Beijing from October 2024 to January 2025 were selected as participants.Among them,25 patients admitted from December 2024 to January 2025 were assigned to an experimental group and received early mobility interventions following the developed pathway.25 patients admitted from October to November 2024 served as a control group and received routine ICU mobility care.Outcomes including diaphragm excursion,muscle strength,ICU length of stay,and adverse events were compared between the 2 groups.Results The graded early mobility pathway achieved an implementation rate of 70.05％in the experimental group,significantly higher than it in the control group(P＜0.001),without increasing adverse events.Post-intervention diaphragm excursion in the experimental group was significantly greater than that in the control group(P=0.018).Conclusion The developed graded early mobility implementation pathway for ICU patients demonstrates scientific rigor and clinical practicality.It provides a reference for the widespread and effective implementation of early mobility in ICUs,standardizing its clinical application.

Objective To compare the safety and efficacy of flow diverter with adjunctive spring coils(FAC)and simple flow diverter(FD)in the treatment of large or giant intracranial aneurysms.Methods The clinical data of 48 patients with large or giant intracranial aneurysm(55 intracranial aneurysms in total),who were treated at the First Affiliated Hospital of Zhengzhou University of China from January 2018 to September 2023,were retrospectively analyzed.According to the treatment method,the patients were divided into pure FD group and FAC group.The aneurysm occlusion rate and the incidence of procedure-related complications were compared between the two groups.Univariate and multivariate logistic regression analyses were used to identify risk factors for procedure-related complications.Results A total of 55 intracranial aneurysms detected in the 48 patients were included in this study.The median maximum diameter of aneurysms was 20.25 mm(16.45,24.62 mm).Among them,12 aneurysms were treated with FD alone,and 43 aneurysms were treated with FAC.The median follow-up time was 6.63 months(5.88,8.07 months).Compared with pure FD group,in FAC group the occlusion rate of aneurysms was significantly higher(86.1％vs.50.0％,P=0.023),while there was no statistically significant difference in the incidence of procedure-related complications between the two groups(18.18％vs.16.67％,P=1.000).Multivariate logistic regression analysis showed that the use of more than one stent(OR=6.63,95％CI=1.10-39.88,P=0.039)and the difference between the distal parent artery diameter and the stent diameter(Dd)(OR=7.00,95％CI=1.4-35.7,P=0.019)were the independent risk factors for procedure-related complications.The area under the receiver operating characteristic curve(AUC)of the receiver operating characteristic curve(ROC)for distal parent artery Dd was 0.854(95％CI=0.746-0.963).Conclusion For the treatment of large or giant intracranial aneurysms,FAC is clinically safe and effective.The mid-term follow-up aneurysm occlusion rate of FAC is higher than that of simple FD treatment.The use of more than one stent and the distal parent artery Dd are the independent risk factors for procedure-related complications in the treatment of large or giant intracranial aneurysms with FD.
