Thyroid Eye Disease (TED), also known as Graves' orbitopathy, is an autoimmune condition that causes inflammation and tissue expansion behind the eyes, leading to bulging eyes (proptosis), double vision, and pain. Currently, intravenous glucocorticoids (steroids) are the standard first-line treatment. However, approximately 20-30% of patients do not respond to steroids, or cannot tolerate their side effects. This study aims to evaluate the safety and efficacy of Tofacitinib, an oral medication known as a Janus kinase (JAK) inhibitor, as a rescue therapy for these difficult-to-treat cases. Tofacitinib works by blocking specific signaling pathways (JAK-STAT) that drive inflammation and fibrosis in the eye socket. In this study, patients with moderate-to-severe active TED who are resistant to or intolerant of steroids will receive Tofacitinib tablets (5 mg twice daily) for 24 weeks. The researchers will assess whether the treatment can effectively reduce eye bulging and improve clinical activity scores.

This study is a prospective, single arm phase II clinical trial aimed at patients with advanced non-small cell lung cancer resistant to EGFR-TKI. The aim is to evaluate the efficacy and safety of trilaciclib in bone marrow protection before monotherapy with sacituzumab tirumotecan. Patients with advanced non-small cell lung cancer resistant to EGFR-TKI, after signing informed consent, will be screened for eligible subjects who meet the inclusion criteria. Prior to receiving treatment with sacituzumab tirumotecan, they will be treated with trilaciclib until disease progression or intolerable toxicity occurs. Record the dynamic changes of whole blood cell count; Hematological toxicity, including febrile neutropenia and associated infections; Transfusion of blood products and supplementation of hematopoietic raw materials. Perform tumor imaging evaluation according to RECIST 1.1. Baseline imaging examination should be conducted within 21 days prior to the first administration, and tumor imaging evaluation shall be conducted every 6 weeks (± 7 days) from the first study drug administration, or the frequency of imaging evaluation may be increased when there are clinical indications. Subjects who terminate the study drug treatment due to intolerable toxicity or other non disease progression reasons continue to receive tumor evaluation follow-up until disease progression, withdrawal from the study, or death (whichever occurs earliest). After the screening period and one cycle of treatment, subjects may choose to undergo whole-body PET/CT imaging for exploratory analysis.

This research protocol outlines an exploratory study on the combination of early-life fecal microbiota transplantation (yFMT) with immunotherapy and chemotherapy in patients with microsatellite stable metastatic colorectal cancer (MSS mCRC). The single-center, single-arm study aims to assess the safety of yFMT in conjunction with immunotherapy and chemotherapy, with a secondary focus on exploring its efficacy and impact on the patients' immune microenvironment. The study will enroll 10 patients aged 18-75 who have progressed after first-line chemotherapy and targeted therapy. The intervention involves six sessions of yFMT every two weeks, alongside PD-1 inhibitor immunotherapy and FOLFIRI chemotherapy. The primary endpoints are the incidence of serious adverse events (SAEs), treatment-related adverse events (TRAEs), and intervention adjustments due to adverse events, while secondary endpoints include progression-free survival (PFS), objective response rate (ORR), and overall survival (OS). The study is expected to last two years from initiation to data analysis completion, and it will be conducted at the Gastrointestinal Tumor Surgery Department of the First Affiliated Hospital of Xiamen University.

This is an observational cohort study designed to (1) evaluate whether Gallium-68 (68Ga)-labeled fibroblast activation protein inhibitor ligand LM3 (68Ga-FAPI-LM3) positron emission tomography/computed tomography (PET/CT) improves the accuracy of nasopharyngeal carcinoma (NPC) staging, and (2) determine whether Gallium-68-labeled programmed death-ligand 1 (68Ga-PD-L1) PET/CT imaging parameters can provide early prediction of response to neoadjuvant immunotherapy. The study will assess the sensitivity and specificity of each tracer for staging and for predicting therapeutic response, analyze changes in tumor uptake parameters on 68Ga-FAPI-LM3 and 68Ga-PD-L1 PET/CT before and after treatment, and compare treatment efficacy and survival outcomes between patients with different degrees of residual PET uptake and between those who did and did not receive neoadjuvant immunotherapy. The primary question it aims to answer is: Does 68Ga-FAPI-LM3 PET/CT improve the accuracy of NPC staging, and can 68Ga-PD-L1 PET/CT imaging parameters provide an early prediction of response to neoadjuvant immunotherapy? Participants will be patients with biopsy-proven nasopharyngeal carcinoma who undergo 68Ga-FAPI-LM3 and/or 68Ga-PD-L1 PET/CT as part of clinical care or a research protocol. Tumor uptake metrics (e.g., maximum standardized uptake value (SUVmax), mean standardized uptake value (SUVmean), metabolic/volumetric indices) will be measured pre- and post-treatment; diagnostic performance (sensitivity, specificity) and associations between uptake changes and clinical outcomes (response rates, progression-free and overall survival) will be calculated.

Semaglutide has effects that include lowering blood sugar, reducing weight, and improving cardiovascular and renal outcomes, and it is now widely used in clinical practice. Given that weight loss is associated with bone loss, its effect on bone health has recently raised concerns. Therefore, the goal of this clinical trial is to learn the effect of semaglutide on bone mineral density and fractures in patients with type 2 diabetes. The investigators will compare semaglutide combined with metformin to metformin alone to see if semaglutide treatment has effects on bone mineral density and bone turnover markers in patients with type 2 diabetes after 12 months. The intervention group will receive semaglutide combined with metformin for 12 months, while the control group will receive metformin alone for the same duration. After 12 months of treatment, the investigators will compare the bone mineral density, fracture incidence, and levels of bone turnover markers between the two groups.
