Purpose: Many efforts have been tried to evaluate multiple system atrophy (MSA)-related cognitive impairment, however, there is still lacking of effective approach. In this study, for the first time, we developed the individual metabolic radiomics networks (IMRN) using [F]FDG PET imaging to investigate brain metabolic connectivity patterns of MSA and validated the usefulness of IMRN-based predictive model for MSA-related cognitive impairment.
Methods: In this retrospective study, we recruited 115 MSA patients with [F]FDG PET/CT scans.

Objective: Multiple system atrophy (MSA) is a progressive neurodegenerative disorder with complex clinical manifestations, which is essential for patient management and mechanistic understanding of MSA. In this study, we aimed to use disease progression modeling (SuStaIn model) to elucidate the in vivo spatiotemporal progression patterns of brain glucose metabolism in MSA patients, and investigate the differential profiles of clinical characteristics and dopaminergic function among the identified progression-related subtypes.
Methods: A total of 192 participants (117 MSA patients [70 MSA-P, 47 MSA-C] and 75 healthy controls) who underwent [F]FDG PET scans, with 82 MSA patients additionally receiving [F]FP-CIT PET imaging were retrospectively enrolled.
Introduction: Diabetes is a significant modifiable risk factor for cognitive dysfunction. There are currently no effective treatments that delay or reverse the progression of cognitive dysfunction. Accumulating evidence demonstrates that specific antidiabetes medications hold promise in improving cognitive function.

Objective: To evaluate the efficacy and safety of Xiangshao granules in improving clinical symptoms and regulating serum hormone levels in patients with menopausal syndrome (MPS).
Methods: This study was developed according to the PRISMA 2020 guidelines. Eight databases including PubMed, Web of Science, The Cochrane Library, Embase, CNKI, CBM, Wanfang Database, and VIP database were searched for randomized controlled trials (RCTs) of Xiangshao Granules in the treatment of MPS.
Physical exercise is essential for skeletal integrity and bone health. The gut microbiome, as a pivotal modulator of overall physiologic states, is closely associated with skeletal homeostasis and bone metabolism. However, the potential role of intestinal microbiota in the exercise-mediated bone gain remains unclear.

Aims: To explore serum exosomal microRNAs (miRNAs) as risk biomarkers for early detection of cognitive impairment in type 2 diabetes mellitus (T2DM) patients.
Materials And Methods: This study included two phases: a discovery phase and a validation phase. To detect adipose tissue exosomal biomarkers for T2DM patients, small RNA sequencing was conducted on a discovery population consisting of six T2DM patients and five subjects with normal glucose tolerance.

Introduction: Progressive supranuclear palsy (PSP) is a neurodegenerative disorder with diverse clinical presentations that are linked to tau pathology. Recently, Subtype and Stage Inference (SuStaIn) algorithm, an innovative data-driven method, has been developed to model both the spatial-temporal progression and subtypes of disease. This study explores PSP progression using F-fluorodeoxyglucose (FDG) positron emission tomography (PET) imaging and the SuStaIn algorithm to identify PSP metabolic progression subtypes and understand disease mechanisms.

Bone is a complex organic-inorganic composite tissue composed of ∼30% organics and ∼70% hydroxyapatite (HAp). Inspired by this, we used 30% collagen and 70% HAp extracted from natural bone using the calcination method to generate a biomimetic bone composite hydrogel scaffold (BBCHS). In one respect, BBCHS, with a fixed proportion of inorganic and organic components similar to natural bone, exhibits good physical properties.
