Objective:
To evaluate the diagnostic potential of fluid suppression (FS) techniques combined with amide proton transferweighted imaging (APTw) for assessment of isocitrate dehydrogenase (IDH) mutation status, glioma subtypes, and tumor proliferation.
Materials and Methods:
This retrospective study included 117 patients with adult-type diffuse gliomas. Conventional APTw, FSAPTw, and spillover-corrected FS-APTw (SCFS-APTw) metrics were calculated from 3T MRI data in tumor parenchyma, necrotic or cystic regions, and contralateral normal-appearing white matter. APTw signals were compared across the three techniques within each region, between IDH-mutant and IDH-wildtype gliomas, and among astrocytoma, oligodendroglioma, and glioblastoma subtypes. Diagnostic performance for distinguishing IDH mutation status and glioma subtypes was assessed using receiver operating characteristic (ROC) analysis. Correlations between APTw metrics and Ki-67 expression were also analyzed.
Results:
Both FS-APTw and SCFS-APTw significantly reduced signal intensity in tumor parenchyma and necrotic or cystic regions, with SCFS-APTw demonstrating a stronger suppression effect. IDH-wildtype gliomas showed significantly higher APTw metrics than IDH-mutant gliomas (all P < 0.001). Glioblastomas exhibited significantly higher metrics than oligodendrogliomas (all corrected P ≤ 0.015) and astrocytomas (all corrected P < 0.001). SCFS-APTw achieved the highest area under the ROC curve (AUC) of 0.846 for identification of IDH mutation status. For differentiation between astrocytomas and glioblastomas, the 90th percentile of APTw yielded the highest AUC (0.860), followed by SCFS-APTw (0.849). For discrimination between oligodendrogliomas and glioblastomas, the highest AUC (0.832) was obtained using the 90th percentile of SCFS-APTw. None of these metrics successfully differentiated oligodendrogliomas from astrocytomas. SCFS-APTw demonstrated the strongest correlation with Ki-67 expression (r = 0.451).
Conclusion
FS techniques effectively reduce elevated APTw signals originating from fluid compartments. Their combination with APTw imaging enables evaluation of IDH mutation status, glioma subtypes, and tumor proliferative activity in adulttype diffuse gliomas.

Digital and intelligent technologies serve as the core engine driving the inheritance of the essence and the innovation while upholding the fundamentals of traditional Chinese medicine(TCM). Currently, the digital and intelligent transformation of TCM has undergone four developmental stages, exhibiting inherent characteristics such as long-term inevitability, objective standardization, and ecological evolution. By introducing quantitative metrics, digital and intelligent technologies have achieved breakthroughs in TCM knowledge inheritance and innovation, clinical diagnosis and treatment, and herbal medicine supply. The practical applicability of methodological innovations has been empirically validated, though significant disparities exist in technological adaptability and application depth across different fields. Overall, the digital and intelligent transformation of TCM remains in its nascent stage, grappling with multiple structural challenges:weak data foundations, inadequate technological adaptability, incomplete institutional frameworks, shortages of multidisciplinary talent, lagging policies and regulations, and urban-rural digital divide. In order to foster sustainable development and modernization of TCM, this paper establishes a six-dimensional collaborative governance framework of encompassing data, technology, organization, institutions, environment and ethics, which is rooted in data governance and digital governance theories. Future efforts should center on standardization, integration, and ecosystem development to build a data and technology foundation. Focus should be placed on deepening innovation and application of key TCM-specific technologies, while simultaneously strengthening interdisciplinary talent cultivation, improving institutional mechanisms and policy frameworks, and increasing support for rural areas. By adopting a people-centered and technology-empowered approach, we can overcome developmental constraints and unleash the powerful driving force of digital and intelligent technologies for the inheritance of TCM.

ObjectiveHyperlipidemia (HLP) is a chronic metabolic disease characterized by abnormal lipid metabolism and is one of the important risk factors for the occurrence of cardiovascular and cerebrovascular diseases. Its incidence has increased year by year, showing a trend toward younger onset. The overall prevalence of HLP among adults in China is as high as 40.40%. Although existing animal models provide important tools for research on the mechanisms of HLP, they generally show insufficient clinical concordance and lack the combined disease-syndrome characteristics of traditional Chinese medicine (TCM) and Western medicine. This article systematically reviews the research progress of HLP animal models, integrates the clinicopathological characteristics of TCM and Western medicine, and proposes new model construction strategies, aiming to provide an experimental basis for accurately analyzing the pathogenesis of HLP and developing integrated TCM-Western medicine therapies. MethodsBased on literature included in PubMed, CNKI, and Wanfang databases over the past 30 years, the construction methods and evaluation systems of HLP animal models were systematically retrieved and summarized. The concordance of existing animal models was calculated according to the new animal model evaluation method proposed by Professor MIAO Mingsan. ResultsAmong existing Western medicine modeling approaches, genetically modified models showed the highest concordance (72%), followed by dietary induction (66%) and chemical drug induction (60%). The dietary induction method is the most widely used in practice because of its simple operation and mature technology. Existing TCM modeling approaches are classified into three types, i.e., spleen deficiency type, phlegm syndrome type, and liver-kidney yin deficiency type. Among them, the phlegm syndrome type shows a high degree of concordance. However, all three types have the problem of non-objective evaluation indicators and insufficient application of tongue and pulse assessment. ConclusionThe construction of existing HLP disease-syndrome combined animal models is still mainly based on Western medicine modeling methods and lacks adequate reflection of TCM syndromes. In the future, HLP animal models that conform to the clinical disease-syndrome characteristics of both TCM and Western medicine may be constructed through multifactor composite modeling strategies, intelligent tongue image analysis via robot learning, objective pulse detection, the establishment of objective evaluation systems for TCM syndromes through big data computing, and the application of cutting-edge technologies.

Objective:To assess the impact of induction chemotherapy sensitivity on the prognosis and larynx preservation rates in patients with locally advanced hypopharyngeal cancer and to identify risk factors influencing induction chemotherapy sensitivity.Methods:This study included patients with locally advanced (stage III-IV) hypopharyngeal cancer who received induction chemotherapy as initial treatment at the Eye & ENT Hospital of Fudan University between August 2017 and September 2022. Based on the Response Evaluation Criteria in Solid Tumors (RECIST) 1.1, enrolled patients were classified into the sensitive group and the resistant group according to their response to induction chemotherapy. Chi-square tests and Log-rank tests were used to compare the objective response rate (ORR), overall survival (OS), progression-free survival (PFS), and laryngeal preservation rate (LPR) between groups. Propensity score matching (PSM) was employed to accurately evaluate the impact of induction chemotherapy sensitivity on prognosis in real-world settings. Univariate and multivariate logistic regression analyses were performed to identify risk factors for induction chemotherapy resistance in locally advanced hypopharyngeal cancer.Results:A total of 197 patients with locally advanced hypopharyngeal cancer who received induction chemotherapy as initial treatment were included in, comprising 195 males and 2 females, with ages ranging from 36 to 74 years. Among them, 155 patients (78.68%) were classified into the sensitive group and 42 patients (21.32%) into the resistant group. The overall response rate (ORR) of induction chemotherapy in this cohort was 78.68%, with a five-year OS rate of 63.7%. The sensitive group had significantly better OS (mOS 6.32 vs. 5.05 year), PFS (mPFS 5.71 vs. 3.09 year) and a significantly higher LPR (91.6% vs. 69.0%) ( P<0.05). After propensity score matching, all covariates were balanced between the two groups, and the sensitive group showed significant improvement in OS ( P<0.05), while, no significant difference was observed in PFS and LPR between the two groups. Logistic regression analysis revealed that risk factors for induction chemotherapy failure in locally advanced hypopharyngeal cancer included: smoking status ( OR [95% CI]=4.751 [1.887-11.961]), tumor location in the posterior pharyngeal wall ( OR [95% CI]=2.988 [1.264-7.063]), and cN2-3 stage ( OR [95% CI]=3.641 [1.109-11.954]) ( P<0.05). Conclusions:Induction chemotherapy sensitivity significantly affects the prognosis of locally advanced hypopharyngeal cancer, which is influenced by various risk factors, including smoking status, tumor sublocation, and clinical N stage.

Alzheimer's disease (AD) is a neurodegenerative disease with clinical hallmarks of progressive cognitive impairment. Synergistic effects of the Aβ-Tau cascade reaction are tightly implicated in AD pathology, and microglial NLRP3 inflammasome activation drives neuronal tauopathy. However, the underlying mechanism of how Aβ mediates NLRP3 inflammasome remains unclear. Herein, we determined that oligomeric Aβ (o-Aβ) bound to microglial Kv2.1 and promoted Kv2.1-dependent potassium efflux to activate NLRP3 inflammasome resulting in neuronal tauopathy by using Kv2.1 inhibitor drofenine (Dfe) as a probe. The underlying mechanism has been intensively investigated by assays with Kv2.1 knockdown in vitro (si-Kv2.1) and in vivo (AAV-ePHP-si-Kv2.1). Dfe deprived o-Aβ of its capability to promote microglial NLRP3 inflammasome activation and neuronal Tau hyperphosphorylation by inhibiting the Kv2.1/JNK/NF-κB pathway while improving the cognitive impairment of 5×FAD-AD model mice. Our results have highly addressed that the Kv2.1 channel is required for o-Aβ-driven microglial NLRP3 inflammasome activation and neuronal tauopathy in AD model mice and highlighted that Dfe as a Kv2.1 inhibitor shows potential in the treatment of AD.

Obesity usually exacerbates the immunosuppressive tumor microenvironment (ITME), hindering CD8+ T cell infiltration and function, which further represents a significant barrier to the efficacy of immunotherapy. Herein, a multifunctional liposomal system (CR-Lip) for encapsulating celastrol (CEL) was utilized to remodel obesity-related ITME and improve cancer immunotherapy, wherein Ginsenoside Rg3 (Rg3) was detected interspersed in the phospholipid bilayer and its glycosyl exposed on the surface of the liposome. CR-Lip had a relatively uniform size (116.5 nm), facilitating favorable tumor tissue accumulation through the interaction between Rg3 and glucose transporter 1 overexpressed in obese tumor cells. Upon reaching the tumor region, CR-Lip was found to induce the immunogenic cell death (ICD) of HFD tumor cells. Notably, the level of PHD3 in HFD tumor cells was effectively boosted by CR-Lip to effectively block metabolic reprogramming and increase the availability of major free fatty acids fuel sources. In vivo, experiments studies revealed that the easy-obtained nano platform stimulated enhanced the production of various cytokines in tumor tissues, DC maturation, CD8+ T-cell infiltration, and synergistic anticancer therapeutic potency with aPD-1 (tumor inhibition rate = 82.1%) towards obesity-related melanoma. Consequently, this study presented an efficacious approach to tumor immunotherapy in obese mice by encompassing tumor eradication, inducing ICD, and reprogramming metabolism. Furthermore, it offered a unique insight into a valuable attempt at the immunotherapy of obesity-associated related tumors.
