This is a single-center, observational imaging study designed to evaluate the in vivo morphology of the male urethral internal sphincter ring using magnetic resonance diffusion tensor imaging (MRI-DTI) fiber tracking and to investigate its relationship with prostate base morphology. Male participants undergoing clinically indicated pelvic, seminal vesicle, or prostate-related MRI-DTI examinations will be included. The study population may include patients with benign prostatic enlargement, younger men undergoing MRI for suspected cryptorchidism or suspected seminal vesiculitis, and patients with prostate cancer scheduled to receive androgen deprivation therapy (ADT). All participants will undergo T2-weighted imaging and DTI. T2WI-DTI image registration, dual-region-of-interest fiber tracking, and three-dimensional reconstruction will be used to visualize ring-like muscle fiber structures in the bladder neck, prostate base, and proximal urethral region. The cross-sectional imaging cohort will be used to assess the associations between prostate-side morphological parameters, including prostate volume, prostate base diameter or area, and intravesical prostatic protrusion, and sphincter-ring parameters, including ring inner diameter and ring area. The ADT paired cohort will undergo MRI-DTI before treatment and during follow-up after ADT to evaluate whether reduction in prostate volume and prostate base morphology is accompanied by corresponding changes in the urethral internal sphincter ring. This study will not alter the participants' existing clinical diagnostic or treatment pathways. Imaging data will be analyzed using standardized post-processing and quantitative measurement procedures. The results may provide in vivo imaging evidence for age- and prostate-related displacement and morphological remodeling of the male urethral internal sphincter and may inform future surgical strategies for identifying, preserving, or reconstructing proximal urinary continence-related structures.

This is a prospective, assessor-blinded, randomized controlled study designed to evaluate whether large language model (LLM)-assisted decision support can improve village doctors' abilities in the comprehensive management of patients with type 2 diabetes mellitus and hypertension. For each standardized clinical case, two village doctors will independently review the same patient information and develop management plans. An independent statistician will randomly assign one doctor to receive LLM-assisted decision support, while the other will complete the assessment without assistance. All management plans and questionnaire responses will be de-identified and evaluated by an independent expert panel blinded to group allocation. The study will compare the quality of clinical decision-making, risk assessment, treatment recommendations, and follow-up planning between the LLM-assisted and control groups.

This study aims to apply traditional auricular press-needle acupuncture to treat sleep disturbances in elderly patients (aged ≥65 years) with comorbid diabetes mellitus and hypertension in rural areas of China. Given the complex bidirectional relationship between diabetes mellitus with hypertension and sleep disturbances, this cluster randomized trial is designed to test whether a village doctor-led intervention model supported by telemedicine can improve sleep disturbances in patients with comorbid diabetes mellitus and hypertension, compared to sham auricular press-needle acupuncture. Participants will be recruited by local village doctors according to the inclusion and exclusion criteria. The protocol is based on Traditional Chinese Medicine theory for core point selection: Heart, Liver, Kidney, Shenmen, and Forehead area, along with optimized medication regimens supported by remote cardiovascular specialists. The investigators will evaluate the overall improvement in sleep disturbances using the Pittsburgh Sleep Quality Index (PSQI) at the end of the 6-week treatment period, and assess sleep disturbances, anxiety, depression, daytime sleepiness, and fatigue at 12 weeks.

This study aims to evaluate how transcranial focused ultrasound (tFUS) technology can promote neural network remodeling and functional recovery after stroke. By integrating signals from electroencephalography (EEG) and magnetic resonance imaging (MRI), the study will investigate how activating or inhibiting specific brain regions affects motor and cognitive recovery. The goal is to improve patients' motor and cognitive functions, reduce long-term disability, and enhance quality of life. The study also seeks to optimize stimulation parameters to maximize rehabilitation outcomes and explore the mechanisms underlying neuroprotection and functional reconstruction after stroke. This is a case-control study involving a total of 60 participants. Participants will be ischemic stroke survivors aged 18-75 years, with first-ever stroke onset between 21 days and 6 months, stable vital signs, no consciousness disorders, and the ability to provide informed consent and cooperate with assessments. Eligible participants must have unilateral limb motor impairment, with an upper extremity modified Ashworth score ≤3, Brunnstrom stage II-V, and an upper extremity Fugl-Meyer Assessment (FMA-UE) score between 15 and 60. Participants will be assigned to either a neuromodulation group (receiving multi-modal neuromodulation targeting specific brain regions) or a control group (receiving sham stimulation or conventional treatment). Primary outcome measures include changes in FMA-UE scores, neuroimaging data (CT/MRI), EEG measurements (resting-state and task-state spectral power, functional connectivity), and laboratory markers (complete blood count, CRP, IL-6, S100β, BDNF). Secondary outcome measures include Brunnstrom stage, Ashworth grade, muscle strength, and patient comfort ratings. Safety will be monitored through blood routine tests, blood biochemistry, and coagulation function. Statistical analysis will compare key indicator changes between the neuromodulation and control groups before and after intervention. Independent t-tests (for two groups) or ANOVA (for multiple groups) will be used to assess between-group differences, with non-parametric tests applied for data not following a normal distribution.

Atrial fibrillation (AF) is a common arrhythmia in aging populations and is strongly associated with an increased risk of heart failure (HF) and adverse cardiovascular outcomes. However, early detection of HF among patients with AF remain inadequate in rural settings. This study aims to screen for HF among older adults with AF in rural China and to conduct long-term follow-up in order to observe the disease progression in patients with AF. This study will recruit at least 2,500 elderly individuals aged between 65 and 80 years, with confirmed diagnoses of AF, residing in rural areas. Participants will undergo HF screening using NT-proBNP testing and echocardiographic assessment. Additionally, data will be collected on electrocardiographic signals, seismocardiography, voice, and demographic characteristics. Following data collection, participants will be followed up every three months to monitor the incidence and progression of HF as well as the occurrence of adverse cardiovascular events.

The goal of this observational study is to learn about the influencing factors of chronic heart failure prognosis in heart failure patients. The main question it aims to answer is that what are the influencing factors of clinical outcomes in chronic heart failure. Participants will be collected multiple omics data such as phenotype group, environmental exposure group, intestinal microbiome, genome, metabolome, and noninvasive biomarkers.

This cross-sectional observational study aims to assess healthy lifestyle knowledge, personal health practices, and lifestyle recommendation behaviors among healthcare workers across different levels of healthcare institutions. The study will also collect clinical examination and biochemical indicators to evaluate the health status of participants and explore their associations with lifestyle-related knowledge and behaviors. Healthcare workers play a critical role in promoting healthy lifestyles among patients; however, their own health behaviors and recommendations may vary depending on training background and institutional settings. This study seeks to better understand these differences and identify potential gaps between knowledge and practice. The findings of this study may help inform targeted training strategies and support the development of effective health promotion programs for healthcare professionals, ultimately improving the quality of lifestyle guidance provided to patients.
