ObjectiveTo investigate the clinical effects and safety of Shuhe Granules （舒和颗粒） in patients with rheumatoid arthritis （RA） comorbid with insomnia. MethodsA single-arm prospective exploratory design was adopted. Thirty RA patients comorbid with insomnia and diagnosed with the traditional Chinese medicine （TCM） syndrome of kidney-heart deficiency and qi-blood disharmony were enrolled. On the basis of maintaining their original RA treatment regimens， all patients received oral Shuhe Granules， one dose per day， for 12 consecutive weeks. The outcomes were assessed before treatment and at weeks 4， 8， and 12 after treatment. Sleep and related psychosomatic function were evaluated using the insomnia severity index （ISI）， Pittsburgh sleep quality index （PSQI）， fatigue severity scale （FSS）， patient health questionnaire-9 （PHQ-9）， generalized anxiety disorder-7 （GAD-7）， and Montreal cognitive assessment （MoCA） scores. RA-related assessments included the 28-joint disease activity score based on C-reactive protein （DAS28-CRP）， pain visual analog scale （VAS）， tender joint count （TJC28）， swollen joint count （SJC28）， morning stiffness duration， and health assessment questionnaire （HAQ） score. Laboratory parameters included erythrocyte sedimentation rate （ESR）， serum C-reactive protein （CRP）， anti-cyclic citrullinated peptide antibody （anti-CCP）， and rheumatoid factor （RF） levels. A literature-based historical control group was established through literature retrieval and meta-analysis. The ISI， PSQI， DAS28-CRP， and pain VAS scores were compared between the treatment group in the present study and the historical control group. Safety assessments were also performed. ResultsCompared with baseline before treatment， ISI and PSQI scores decreased at weeks 4， 8， and 12， while MoCA scores increased at weeks 4， 8， and 12. FSS scores decreased at weeks 4 and 12. At weeks 8 and 12， GAD-7 scores， DAS28-CRP scores， duration of morning stiffness， TJC28， and SJC28 were reduced. At week 12， PHQ-9， pain VAS， and HAQ scores significantly decreased （P＜0.05）. FSS and DAS28-CRP scores at week 12 were lower than those at week 4， and CRP levels at week 8 were lower than those at week 4 （P＜0.05）. Compared with the historical control group， the treatment group showed superior improvement in ISI and PSQI scores （P＜0.001）； however， no statistically significant differences were observed between the two groups in DAS28-CRP or pain VAS scores （P＞0.05）. No serious adverse events occurred during the study， and the 4 reported mild adverse events were all considered unrelated to the study medication. ConclusionShuhe Granules significantly improve sleep quality， fatigue， emotional status， cognitive function， RA-related symptoms， and joint function in patients with RA comorbid insomnia， with good safety and tolerability.

Integrin αvβ3 is an important target for tumor imaging and therapy. It is highly expressed on tumor neovascular endothelial cells and various malignant tumor cells， while being nearly absent in normal tissues and quiescent endothelial cells. Positron emission tomography （PET） based on Arg-Gly-Asp （RGD） peptides has been widely applied， yet single-target strategies are limited by tumor heterogeneity. β^- radionuclide-labeled RGD peptides exhibit problems of insufficient tumor uptake and renal accumulation. This review summarizes the preclinical progress in two frontier directions. Dual-targeting strategies combine integrin αvβ3 with prostate-specific membrane antigen （PSMA） or fibroblast activation protein （FAP） to construct heterodimeric probes. Preclinical and clinical studies have demonstrated that dual-targeting probes achieve significantly superior tumor uptake， target-to-background ratios， and lesion detection rates compared to single-target controls， effectively overcoming tumor heterogeneity and improving tumor uptake and detection rate. α radionuclides， by leveraging high linear energy transfer and short tissue range， demonstrate superior antitumor efficacy over β^-radionuclides. In terms of clinical translation， the albumin-binding RGD dimer labeled with lutetium-177 （¹⁷⁷Lu-AB-3PRGD₂） has completed a first-in-human study， preliminarily validating the clinical feasibility of integrin-targeted radionuclide therapy， albeit with limited antitumor activity. Future directions include molecular imaging-based patient selection， optimization of dual-targeting molecular structures， and development of α radionuclide formulations.

Objective:To evaluate the changes in cortical electroencephalogram (EEG) burst suppression rate (BSR) during sevoflurane anesthesia in septic mice and the correlation with cerebral blood perfusion.Methods:Forty SPF male C57BL/6J mice, aged 8-10 weeks, weighing 22-25 g, were divided into 2 groups ( n=20 each) by the random number table method: sham operation group (Sham group) and cecal ligation perforation group (CLP group). The sepsis model was established by cecal ligation and puncture in anesthetized animals. Mice in both groups inhaled 2% sevoflurane for 2 h. During sevoflurane anesthesia, BSR (30 min as an epoch) on electroencephalogram was recorded, and the cortical cerebral blood perfusion was recorded using the laser speckle flow imaging at 30, 60, 90 and 120 min of anesthesia. Results:Compared with Sham group, the cortical EEG BSR was significantly increased, and the cortical cerebral blood perfusion was decreased during sevoflurane anesthesia in CLP group ( P<0.05). Cortical EEG BSR was negatively correlated with cortical cerebral blood perfusion ( P<0.05). Conclusions:Cortical EEG BSR increases during sevoflurane anesthesia in septic mice, which may be related to decreased cortical cerebral blood perfusion.

Metabolic dysfunction-associated steatotic liver disease (MASLD), the most prevalent chronic liver condition globally, lacks adequate and effective therapeutic remedies in clinical practice. Recent studies have increasingly highlighted the close connection between the ubiquitin-proteasome system (UPS) and the progression of MASLD. This relationship is crucial for understanding the disease's underlying mechanism. As a sophisticated process, the UPS govern protein stability and function, maintaining protein homeostasis, thus influencing a multitude of elements and biological events of eukaryotic cells. It comprises four enzyme families, namely, ubiquitin-activating enzymes (E1), ubiquitin-conjugating enzymes (E2), ubiquitin-protein ligases (E3), and deubiquitinating enzymes (DUBs). This review aims to delve into the array of pathways and therapeutic targets implicated in the ubiquitination within the pathogenesis of MASLD. Therefore, this review unveils the role of ubiquitination in MASLD while spotlighting potential therapeutic targets within the context of this disease.

In recent years, the rapid development of artificial intelligence (AI) has revolutionized the whole-course nutritional management of elderly patients. AI technologies, including machine learning and natural language processing, are capable of efficiently processing vast amounts of multidimensional information such as clinical data, laboratory test results, and imaging findings. For instance, machine learning algorithms can efficiently identify complex nutritional metabolism patterns and accurately predict malnutrition and its trends in elderly patients. Following the standard pathway of "screening, assessment, diagnosis, treatment, and monitoring", AI technology empowers the whole-course nutritional management for elderly patients, forming a refined, data-driven management model, and shows great potential in improving the nutritional status of elderly patients, enhancing treatment outcomes, and promoting elderly health.

Objective:To evaluate the effectiveness of the Total Nutritional Therapy (TNT) course initiated by the Chinese Society for Parenteral and Enteral Nutrition (CSPEN) over the 20 years since its implementation in China.Methods:Participants who attended the CSPEN-organized TNT course between 2005 and 2024 were randomly selected as survey subjects. A four-level questionnaire (reaction, learning, behavior, and results) was developed via expert consensus, based on the Kirkpatrick model. An electronic link to the survey, created via Wenjuanxing, was distributed to invite participants to complete the questionnaire.Results:A total of 1,548 healthcare professionals from various specialties who had received TNT course participated in the online survey. Over 93% of participants reported improvements in theoretical knowledge and 94% in enhanced clinical diagnosis and treatment capabilities. Additionally, 65.4% of participants reported a "significant" or "noticeable" increase in the frequency of nutritional screening and assessments, with the frequency of nutritional support therapy utilization increased by 91.2%. Furthermore, 52.6% of respondents perceived a "significant" or "noticeable" career advancement, particularly in professional title promotion and international academic exchanges. The TNT course also positively impacted discipline development and management: 63.6% of the trainees' hospitals established clinical nutrition departments, 58.98% opened nutrition outpatient clinics, and 56.9% formed nutrition support teams. The adoption rate of standardized procedures, such as nutritional screening, exceeded 92.5% in relevant departments.Conclusions:Over the past 20 years, the CSPEN-led TNT course has successfully established a virtuous cycle of "knowledge dissemination–practice transformation–system innovation" in China. It has played a positive role in enhancing the professional competencies of healthcare workers and promoting the development of clinical nutrition as a discipline.

Objective:To investigate the relationship between dynamic alterations in serum albumin (ALB) concentrations and clinical outcomes in hospitalized surgical patients, thus providing a basis for optimizing clinical management strategies.Methods:This study utilized data from a prospective observational cohort study on nutritional status among 7 122 elderly hospitalized patients across 34 tertiary hospitals in 18 Chinese cities. A total of 1 714 surgical patients hospitalized for 7-30 days with complete data were included. Standardized protocols were used to collect demographic data, clinical outcomes, and a range of laboratory results, including nutritional and hematological parameters. Heterogeneous effects of ALB on clinical outcomes were explored. Receiver operating characteristic (ROC) curves were used to determine cutoff values for infection-related complications. Correlation analyses and multiple linear regression models were used to identify independent predictors of the absolute change in ALB (?ALB).Results:Among the surgical patients, 69.7% (1 195/1 714) experienced a decline in ALB levels during their hospital stay, which was significantly associated with the occurrence of both infection- and non-infection-related complications. Simultaneously, a marked decrease in ALB was also significantly correlated with changes in nutritional and inflammatory status during hospitalization, worsening of gastrointestinal symptoms at discharge, and functional activity abnormalities (all P<0.05). ?ALB exhibited a close association with outcome variables such as infection-related complications. Based on the incidence of infection-related complications, a cutoff value for ALB was calculated, dividing patients into a high-risk group ( n=179) and a low-risk group ( n=1 535), and a statistically significant difference in the incidence of infection-related complications was found between these two groups ( P<0.05). Correlation analysis and multiple linear regression modeling revealed that female gender, a higher baseline ALB level, a poorer baseline inflammatory status, an exacerbation of inflammatory status, larger alterations in platelet-to-lymphocyte ratio, and the presence of infection-related complications were predictive factors for a decline in ALB levels among surgical patients during their hospital stay. Conclusions:?ALB serves as a critical indicator of the inflammatory-nutritional interplay, with its magnitude of decline effectively predicting clinical outcomes and nutritional status changes and guiding multidisciplinary interventions in surgical patients.

The high prevalence of frailty in older adults and its close link to adverse outcomes make it a critical public health challenge in the aging global population. Frailty, characterized by multisystem functional decline, significantly increases the risk of falls, disability, and even death, yet its underlying mechanisms remain poorly understood. While the role of gut microbiota as the "second genome" in disease regulation has been widely recognized, its specific mechanisms in the development of frailty syndrome remain to be systematically investigated. This review synthesizes findings from the last decade of international literature to analyze the mechanisms by which gut microbiota dysbiosis contributes to frailty syndrome. We focus on pathways including metabolic disorders, chronic inflammation, oxidative stress, and the oral-gut microbiota axis, aiming to provide insights for clinical diagnosis and treatment.
