High-grade proteinuria is one of the key determinants of adverse renal prognosis in patients with primary membranous nephropathy (PMN).The main purpose of this study is to determine whether Rituximab combined with Cyclosporine is superior to Rituximab monotherapy in inducing remission of proteinuria in patients with PMN.

Patients with relapsed or refractory cutaneous T-cell lymphoma (R/R CTCL) face a poor prognosis and limited therapeutic options. Advanced or relapsed disease yields a 5-year overall survival rate of \<50%. Real-world data show that third-line therapy achieves an ORR of only 45-50% with a median PFS of 1.2 years. Chemotherapy remains dominant (43.1% in the third-line) but offers limited, transient efficacy (median time to next treatment: 4 months) and severe toxicities, leaving a critical unmet need for safe, highly specific targeted therapies. Epigenetic dysregulation is central to CTCL pathogenesis, particularly aberrations in the histone methyltransferase EZH2. As the catalytic subunit of PRC2, EZH2 mediates H3K27me3 to repress target gene transcription. In CTCL, EZH2 frequently undergoes copy number amplification or gain-of-function mutations to drive tumor progression. Targeting EZH2 demonstrates high tumor specificity; EZH2 inhibitors like tazemetostat and valemetostat are already approved for epithelioid sarcoma, follicular lymphoma, and peripheral T-cell lymphoma (PTCL). Preclinically, EZH2 is specifically overexpressed in neoplastic CTCL T cells, and EZH2 inhibitors dose-dependently suppress CTCL cell/tumor growth. Given shared pathogenic mechanisms, PTCL data provide strong reference for CTCL. Valemetostat achieved an ORR of 43.7% and median PFS of 5.5 months in R/R PTCL. Zeprumetostat demonstrated superior efficacy (ORR 61%, median PFS 11.1 months) with a favorable safety profile, leading to its 2025 approval in China for R/R PTCL. Therefore, this single-arm, prospective trial evaluates zeprumetostat in R/R CTCL. Given that CTCL shares essential pathogenetic and epigenetic features with PTCL, and leveraging zeprumetostat's established approval in PTCL, this study represents a rational and mechanistically justified therapeutic expansion rather than an unsupported off-label application.

This prospective randomized controlled study evaluates the clinical efficacy of modified Zhixiao Tongmai Ning in preventing radiation-induced kidney injury in cancer patients. We will assess improvements using routine lab indicators (e.g., glomerular filtration rate, serum creatinine, urine tests), Traditional Chinese Medicine (TCM) syndrome criteria, patient-reported scores, and renal dynamic imaging. The study aims to identify the most suitable patient subgroups and optimal timing for drug use by analyzing baseline factors, radiation parameters, and concurrent treatments, thereby optimizing the formula. Additionally, we will collect blood and urine samples to explore potential mechanisms, focusing on inflammatory factors like TNF-α and IL-6, to support future basic research and clinical application.

This is a prospective, single-center, single-arm Phase I study evaluating GPRC5D-targeted PET/CT imaging in patients with plasma cell disorders, including multiple myeloma. Participants will undergo GPRC5D-targeted PET/CT, 18F-FDG PET/CT, and 68Ga-BCMA PET/CT within 5 days whenever feasible for head-to-head comparison of lesion detection and disease assessment. The study aims to evaluate the safety, feasibility, biodistribution, and diagnostic performance of GPRC5D-targeted PET/CT and to compare its imaging characteristics with currently available molecular imaging modalities in plasma cell disorders.

This randomized, open-label, multicenter phase III study is designed to compare disitamab vedotin plus radiotherapy with gemcitabine plus carboplatin as adjuvant treatment in patients with HER2-expressing upper tract urothelial carcinoma after radical nephroureterectomy (RNU). Eligible patients must have postoperative pathologic stage pT3-pT4N0M0 or pTanyN+M0, HER2 expression defined as immunohistochemistry (IHC) 1+, 2+, or 3+, and be cisplatin-ineligible. Patients will be randomized in a 2:1 ratio to receive disitamab vedotin plus radiotherapy or gemcitabine plus carboplatin. The primary endpoint is 3-year disease-free survival. Secondary endpoints include overall survival, metastasis-free survival, local recurrence-free survival, bladder recurrence-free survival, incidence of adverse events, and patient-reported quality of life.

The purpose of this study is to explore the effectiveness of 18F-G1 PET/CT in patients with solid tumors and hematological malignancies receiving immunotherapy

With the accelerating global aging population, dementia has become a pressing worldwide issue. This project aims to identify specific plasma biomarkers and ocular indicators for the early detection of Alzheimer's disease (AD).

Before effective treatment, the prognosis of patients with AL amyloidosis is very poor, with a median survival of approximately 12 months. In recent decades, with the development of new drugs, the treatment paradigm for AL amyloidosis has undergone significant changes, and the prognosis has improved dramatically. Achieving very good partial response (VGPR) or even complete response (CR) can lead to higher organ response and longer survival. However, not all patients who achieve ≥VGPR reach organ response, which may be related to the presence of small residual plasma cell clones in these patients. The ongoing production of monoclonal light chains deposits into tissues and organs, causing continuous damage, making organ response difficult. With the development of new drugs, the rate of hematologic CR has continuously increased, and the advancement of minimal residual disease (MRD) detection technologies in recent years has led to increasing attention to MRD in AL amyloidosis research. Therefore, in this era of advancing new drugs, MRD negativity may become a higher clinical treatment goal for AL amyloidosis, further improving long-term prognosis for patients. Our department plans to conduct a single-center, prospective clinical study aimed at exploring the MRD status in patients who achieve hematologic CR after first-line induction chemotherapy (Dara-CyBorD), and further investigating whether autologous stem cell transplantation in MRD-positive CR patients who meet transplant criteria can further improve organ response, progression-free survival, and overall survival.

The primary aim is to establish a prospective cohort of patients with plasma cell disorders (PCDs). All of the hospitalized PCD patients who are willing to sign the informed consent form (ICF) will be included in this study. Clinical characteristics, treatment options and responses will be collected. Peripheral blood, bone marrow aspirate and urine samples before and after the treatment will banked for future research. Our team will focus on the clinical and pathological features of PCDs, the correlation between the minimal residual disease (MRD) status and prognosis, and the role of Tumor Microenvironment (TME) in the pathogenesis and progress of PCDs.

This prospective, multicenter, observational cohort study will enroll 60 adults with unresectable larege tumors (longest diameter \> 5 cm) who receive one of two treatment modes: (A) proton P-SABR, in which both the proton partial-SABR boost (course 1) and the subsequent proton CFRT (course 2) are delivered at the proton center; or (B) proton-photon hybrid P-SABR, in which course 1 is delivered with protons at the proton center and course 2 CFRT is delivered with photons. The primary objective is to describe, in each cohort, the incidence of treatment-related grade ≥ 3 acute and late adverse events (CTCAE v5.0). Secondary objectives are dosimetric and the 1-year local control rate (RECIST 1.1, in-field). Participants are followed for up to 5 years.

This is a diagnostic study. This clinical trial aims to evaluate the diagnostic performance and safety of the novel radiotracer 18F-X12 in patients with hepatocellular carcinoma (HCC), and to provide evidence supporting a new approach for its early diagnosis, accurate staging and recurrence assessment.

This study aims to evaluate the efficacy of adjuvant docetaxel chemotherapy following radical radiotherapy in patients with localized high-grade prostate cancer. Eligible participants include those diagnosed with prostate cancer confirmed by biopsy or surgical pathology, with a Gleason score of 9-10 or containing a Gleason 5 component, and no evidence of distant metastasis. Patients will be divided into two groups: the standard treatment group receiving only radical treatment (radiotherapy or surgery), and the standard treatment plus chemotherapy group, receiving four to six cycles of docetaxel chemotherapy after standard treatment. The primary endpoint is Failure-Free Survival (FFS), with secondary endpoints including Biochemical Relapse-Free Survival (BRFS), Metastasis-Free Survival (MFS), Overall Survival (OS), and assessment of adverse events The study aims to better understand the impact of adjuvant chemotherapy on the prognosis of patients with high-risk prostate cancer and determine whether it improves survival outcomes.

This study aims to evaluate the safety, feasibility, and imaging performance of a novel 68Ga-labeled B7-H3 nanobody for immunoPET imaging in patients with osteosarcoma. Participants with suspected or histologically confirmed osteosarcoma will undergo 68Ga-B7-H3 nanobody PET/CT imaging according to the study protocol. Imaging findings will be compared with conventional imaging and, when available, histopathological results. The study will assess tracer biodistribution, tumor uptake, lesion detectability, and safety to determine the potential clinical value of B7-H3-targeted immunoPET for the diagnosis and evaluation of osteosarcoma.

Anxiety and depressive symptoms are prevalent in patients undergoing surgical repair for ureteral stricture, driven by chronic pain, renal function concerns, and surgical uncertainty. Dexmedetomidine has anxiolytic and antidepressant effects but may increase bradycardia and hypotension; esketamine provides rapid antidepressant efficacy but may cause psychiatric side effects. Preliminary studies showed that combined use of low-dose dexmedetomidine and esketamine reduced the prevalence of postoperative depressive symptoms without increasing adverse events. This study is designed to test the hypothesis that perioperative use of low-dose dexmedetomidine-esketamine combination may relieve postoperative depressive symptoms and anxiety in patients undergoing laparoscopic ureteral reconstruction.

Patients after hip surgery often suffer from severe pain. Inadequate analgesia increases the risk of postoperative delirium, myocardial injury, and other complications. Peripheral nerve block is an important component of multimodal analgesia, but conventional local anesthetics (such as plain bupivacaine) provide only approximately 12 hours of analgesic duration, which is far from covering the most painful 72 hours after surgery. Liposomal bupivacaine has a slow-release property, prolonging the analgesic duration up to 72 hours after a single injection. However, its clinical advantages in hip fracture surgery remain controversial. The investigators suppose that, compared with plain bupivacaine alone, preoperative supra-inguinal fascia iliaca block using liposomal bupivacaine combined with plain bupivacaine can further improve analgesia, decrease opioid consumption, and improve postoperative recovery quality within 72 hours in older patients after hip fracture surgery.

Opioids are frequently used for postoperative analgesia but may induce side effects. Opioid-induced respiratory depression is the most dangerous side effect of opioids. Patients with obstructive sleep apnea (OSA) are at higher risk for opioid-induced respiratory depression. Oliceridine is a novel biased μ-opioid receptor agonist that selectively engages the G-protein pathway while reducing β-arrestin recruitment and thus may lower the risk of respiratory depression. The goal of this observational study is to compare the effects of oliceridine versus sufentanil analgesia on the incidence of postoperative respiratory depression in patients with known or suspected OSA in the postoperative period following elective surgery.

Delayed neurocognitive recovery is a common neurocognitive complication in older patients after surgery, especially those with preoperative neurocognitive decline. Transcranial photobiomodulation therapy is a novel neuromodulation technique using transcranial low-power light to modulate brain biological functions. This technique has been used to treat various neurological or psychiatric conditions, including ischemic stroke, traumatic brain injury, and major depression. This study is designed to explore whether using transcranial photobiomodulation therapy during the perioperative period can reduce the incidence of delayed neurocognitive recovery in older patients with pre-existing neurocognitive impairment.

Allogeneic hematopoietic stem cell transplantation is the only curative treatment for malignant hematologic diseases. However, immune rejection is a major limitation in its application. In the "Beijing Protocol", the use of granulocyte colony-stimulating factor (G-CSF) in combination with anti-thymocyte globulin (ATG) can achieve "everyone has a donor". The use of ATG, however, can interfere with the recovery of immune function after transplantation, increasing the risk of life-threatening complications such as viral infections or graft-versus-host disease. Rabbit anti-human T-lymphocyte immunoglobulin (ATLG) is currently approved for the prevention of organ transplant rejection, which is produced differently from ATG. Previous studies have shown that transplant preconditioning with ATLG is effective in preventing graft-versus-host disease and even reduces the incidence of cytomegalovirus, etc. after transplantation. In this study, we will prospectively apply containing ATLG in a cohort of allogeneic hematopoietic stem cell transplantation for malignant hematologic diseases and dynamically observe the state of immune reconstitution of patients after transplantation. We will also compare it with a matched cohort of conventional combined ATGs during the same period to explore the impact of ATLG on immune reconstitution after transplantation.

This is a single-centre, single-arm, open-label, early clinical study to evaluate the safety, tolerability and preliminary efficacy of donor NK cells injection combined with low-dose interleukin-2 in the treatment of acute myeloid leukemia (AML) relapse after allogeneic hematopoietic stem cell transplantation (allo-HSCT).

This is a prospective, single-center, open-label, randomized, controlled phase II clinical trial. The main purpose of this study is to evaluate the efficacy and safety of combining brentuximab vedotin (an anti-CD30 antibody-drug conjugate, ADC) with lisaftoclax (APG-2575, a novel B-cell lymphoma 2 (BCL-2) inhibitor) in patients with CD30-positive cutaneous T-cell lymphoma (CTCL), specifically including mycosis fungoides (MF) and primary cutaneous anaplastic large cell lymphoma (pcALCL). Previous studies suggest that the overexpression of the anti-apoptotic protein BCL-2 may contribute to brentuximab vedotin resistance in CTCL. Researchers hypothesize that adding a highly selective BCL-2 inhibitor (lisaftoclax) can reverse this drug resistance, enhance tumor cell apoptosis, and improve clinical outcomes. In this study, approximately 46 eligible patients will be randomly assigned in a 1:1 ratio to one of two treatment arms: Monotherapy arm (control): Patients will receive brentuximab vedotin intravenously at a dose of 1.8 mg/kg every 3 weeks for a total of 16 cycles. Combination arm (experimental): Patients will receive the same brentuximab vedotin regimen. Additionally, starting from the 6th cycle, patients will receive oral lisaftoclax. To mitigate the risk of tumor lysis syndrome (TLS), a daily dose ramp-up will be implemented in the first cycle of lisaftoclax. Subsequently, lisaftoclax will be administered at a targeted dose of 600 mg daily on days 1 to 10 of each 21-day cycle, for a total of 9 combination cycles. The primary endpoint of the study is the objective response rate (ORR) evaluated at the end of the 16 cycles. Secondary endpoints include the improvement of skin lesions (evaluated by modified severity-weighted assessment tool (mSWAT) score), pruritus relief (visual analog scale (VAS) score), and the incidence of adverse events (AEs). Independent, blinded assessors will be utilized to evaluate the clinical responses to reduce bias.

This is an open-label, single-arm, single-cohort, prospective clinical study evaluating neoadjuvant antibody-drug conjugate therapy combined with immunotherapy and sequential radiotherapy followed by radical surgery in patients with high-risk upper tract urothelial carcinoma (UTUC). Eligible patients will receive neoadjuvant disitamab vedotin (RC48) plus toripalimab, followed by response-guided neoadjuvant radiotherapy and radical nephroureterectomy with bladder cuff excision. The study will assess the safety, feasibility, and preliminary antitumor activity of this multimodal neoadjuvant strategy, with pathological complete response rate as the primary endpoint.

This study aims to establish the diagnostic threshold and efficacy of radioactive counts (CPM) from biopsy specimens in distinguishing cancer-containing from non-cancer-containing cores, using prostate biopsy pathology as the gold standard. On this basis, we quantitatively analyze the correlations between CPM and both tumor ISUP grade and tumor length, thereby inversely calibrating the pathological significance of PSMA PET/CT imaging signals. Furthermore, we seek to preliminarily define a reference range of imaging signal intensity sufficient to safely obviate the need for biopsy, thereby providing direct pathological evidence to advance non-invasive, biopsy-free diagnosis of prostate cancer.

Misoprostol (a prostaglandin E1 analog) is commonly used for cervical ripening and labor induction via vaginal administration. The cervical balloon is another commonly used method that provides mechanical cervical dilation. Both methods are low-cost and widely available. Some meta-analyses have suggested that combined use may shorten the duration of labor, reduce the frequency of tachysystole, and lower NICU admission rates without increasing the risk of cesarean section. However, existing studies are heterogeneous and lack data from Asian populations. This study is being done to see whether combining two common methods of labor induction-misoprostol (a medicine placed in the vagina) and a cervical balloon (placed in the cervix) on the first day of induction-can shorten the time from the start of induction to delivery in first-time mothers during pregnancy . Participants will be randomly assigned to one of two groups: one group will receive misoprostol alone (standard care) on the first day of induction, and the other group will receive misoprostol plus a cervical balloon on the first day of induction. The main outcome measured is the time from the start of induction to delivery. The study will also look at safety outcomes, including the rate of cesarean section, maternal complications, and newborn outcomes.

The goal of this clinical trial is to Evaluate the Safety and Preliminary Efficacy of Human Umbilical Cord Mesenchymal Stem Cell-Derived Exosomes in the Treatment of Adult Type 2 Diabetes Mellitus.

This is a prospective, randomized, double-blind, placebo-controlled multicenter clinical study targeting cirrhosis patients with Spontaneous Bacterial Peritonitis(SBP), aiming to evaluate whether adding Bifidobacterium quadruple probiotics can improve infection control rates and reduce SBP recurrence. Meanwhile, by extending the follow-up period into a real-world clinical observation phase, the study will assess whether Bifidobacterium quadruple probiotics can lower SBP recurrence and extend the lifespan of cirrhosis patients. The primary endpoint of the study is the recurrence rate of SBP during the double-blind treatment period. The study plans to enroll 360 patients.
