Clinical trials

Complicated intra-abdominal infection (cIAI) triggers dysregulated systemic inflammation and immune paralysis leading to high organ failure and death risk. Ulinastatin is a protease inhibitor with anti-inflammatory properties, but its dose-related effects on immune-inflammation of cIAI patients remain unclear. This single-center single-blinded three-arm randomized controlled pilot study enrolls adult cIAI patients (≥18 years, SOFA≥2) at Fujian Medical University Union Hospital. Eligible patients are randomized into low-dose ulinastatin, high-dose ulinastatin and normal saline placebo groups (1:1:1, 5 days intravenous treatment plus standard care), total planned enrollment 165 participants after 10% dropout adjustment. Primary endpoint is Day5 change of Systemic Immune-Inflammation Index (SII); secondary outcomes include serial inflammatory biomarkers, SOFA variation, organ dysfunction, hospitalization duration, 28-day mortality and safety profiles. This pilot aims to clarify ulinastatin's immune-modulating effect and inform future large RCT design.

Based on the high-quality Parkinson's disease cohort population and biological sample database in the early stage of the team, multi-dimensional intelligent wearable device technology and machine learning were used to screen and classify digital biomarkers in the prodromal PD cohort, early PD cohort and healthy population cohort. Using peptide nanoprobes, metabolomics and Simoa technology to find the pathological molecular biomarkers of high-purity blood neurogenic exosomes in the prodromal stage of PD cohort, early PD cohort and healthy population cohort, and conduct classification and combination study. The association analysis was used to explore the specific internal relationship between digital biomarkers and neurogenic exosome molecular biomarkers, to explore the potential relationship between the two types of biomarkers, and to further apply machine learning methods to establish a fusion model for early diagnosis of PD including markers related to digital phenotype and pathological molecular mechanism, and to verify it clinically. The research results of this project are expected to bring new strategies for the early diagnosis of PD biomarkers, provide theoretical support for clinical transformation, and have important clinical significance for achieving the goal of early diagnosis and early treatment.

The prevention and treatment of patients with multiple keloids throughout the body are extremely challenging. Keloids are highly resistant, refractory, and prone to recurrence, and are thus known as the "cancer that does not kill". At present, the main clinical strategy for such patients is staged surgical resection, followed by adjuvant local radiotherapy. When signs of recurrence appear, local injection of triamcinolone acetonide plus 5-fluorouracil (5-Fu) is administered as supplementary treatment. However, these two combination therapies have obvious limitations. Adjuvant postoperative radiotherapy is associated with a high incidence of local skin adverse reactions, including radiodermatitis and delayed wound healing. Late complications may occur weeks or months after treatment, such as permanent hyperpigmentation and hypopigmentation, skin atrophy, fibrosis, scabbing and desquamation, and intractable ulcers. In addition, radiotherapy is not suitable for some young female patients and children when keloids are located near organs such as the thyroid gland and gonads. Injection of triamcinolone acetonide plus 5-Fu causes significant pain and requires repeated sessions. Potential risks include local ulceration, hyperpigmentation, telangiectasia, and menstrual irregularities in female patients. Therefore, there is an urgent clinical need for a pathological scar prevention and treatment technique that can rapidly relieve discomfort, promote scar atrophy, cause no secondary injury, carry low risks, have a short recovery period, provide high comfort during treatment, and be applicable to large-area or multiple pathological scars across the body. Our research team previously observed in clinical practice that wide-band ultrasound (Universal Beauty® Type I Ultrasound Therapeutic Device) combined with traditional Chinese medicine (TCM) preparations can release abnormally accumulated and contracted collagen fibers in scar tissue via ultrasonic energy. Meanwhile, ultrasound promotes the penetration of TCM into scar lesions, exerting effects of infection control, inflammation inhibition, subsidence of redness and swelling, and relief of itching and pain. Compared with conventional scar therapies, this approach achieves rapid symptom control, no secondary damage, no obvious side effects, a short recovery period, and high treatment comfort. It shows particularly significant advantages for large-area or multiple pathological scars throughout the body that are difficult to treat with traditional methods. Preliminary treatment in a small number of volunteers with multiple keloids has achieved satisfactory outcomes without obvious adverse reactions. The purpose of this study is to verify the efficacy and safety of wide-band ultrasound combined with TCM preparation (Chuang Li Fu) in the prevention and treatment of keloids through this clinical trial.

The goal of this clinical trial is to learn whether intravesical instillation of human umbilical cord mesenchymal stem cell-derived exosomes combined with sodium hyaluronate is safe and effective for treating radiation cystitis. Radiation cystitis is a complication that may occur after pelvic radiotherapy. Common symptoms include blood in the urine, frequent urination, urgent urination, and painful urination. The main questions this study aims to answer are: Can human umbilical cord mesenchymal stem cell-derived exosomes combined with sodium hyaluronate improve blood in the urine in participants with radiation cystitis? Can this combined treatment help repair injury to the bladder lining and blood vessels? What discomfort or medical problems may occur during the treatment? Researchers will compare four treatment approaches: human umbilical cord mesenchymal stem cell-derived exosomes combined with sodium hyaluronate, human umbilical cord mesenchymal stem cell-derived exosomes alone, sodium hyaluronate alone, and normal saline as a control. By comparing these groups, researchers hope to find out whether the combined treatment works better than either treatment alone or the control treatment. Participants will: Be screened to confirm whether they are eligible for the study; Sign an informed consent form and complete baseline assessments; Be randomly assigned to one of four treatment groups; Receive intravesical instillation once a week for 4 weeks; Attend follow-up visits at 1 month, 3 months, and 6 months after treatment; Be assessed for blood in the urine, urinary symptoms, cystoscopy findings, quality of life, and safety. This study may help provide a new treatment option for radiation cystitis and further evaluate the safety and early effectiveness of this treatment.

This study aims to investigate the clinical efficacy of haploidentical-cord blood hematopoietic stem cell transplantation in patients with acute myeloid leukemia (AML) and high-risk myelodysplastic syndromes (MDS), and to analyze the impact of different engraftment patterns (haploidentical engraftment versus cord blood engraftment) on clinical outcomes. By comparing the efficacy of haploidentical-cord blood transplantation in different subtypes of AML and MDS, this research will explore its unique advantages and comparative effectiveness relative to conventional transplantation strategies, so as to provide new evidence for clinical practice. Specific research objectives I. To evaluate the efficacy of haploidentical-cord blood hematopoietic stem cell transplantation for AML and high-risk MDS, including the speed of hematopoietic recovery, immune tolerance, and long-term survival rates. II. To compare the effects of different engraftment patterns (haploidentical engraftment vs. cord blood engraftment) on quality of life, immune tolerance, early complications, and long-term prognosis. III. To identify the clinical advantages and indications of haploidentical-cord blood transplantation through data analysis, and to provide a theoretical basis for clinical decision-making. Novelty of the Study I. Innovation in Hematopoietic Stem Cell Infusion Schedule The present study employs a sequential infusion strategy: haploidentical stem cells are infused on Day 0, and umbilical cord blood cells are infused on Day +6 after transplantation.In contrast to the conventional approach used at most domestic and international centers (including the uzhou Protocol), in which both stem cell sources are infused simultaneously on Day 0, the current protocol delays cord blood infusion. This design confers potential advantages for immune reconstitution and long-term cord blood engraftment. II. Unique Myeloablative Conditioning Regimen The conditioning regimen used in this study is as follows: Fludarabine 25 mg/m² for 5 days, Cytarabine 2 mg/m² for 5 days, intravenous Busulfan 3.2 mg/kg for 3 days, ATG 5 mg/m² for 2 days, Melphalan 60 mg/m² for 2 days, and CTX 50.0 mg/kg daily for 2 days. (For patients in complete remission (CR) with negative MRD before transplantation, Fludarabine and Cytarabine are administered for 3 days instead of 5 days.) Distinct from regimens at other centers, our team administers cyclophosphamide within the critical window after haploidentical stem cell infusion but before cord blood infusion, establishing a novel sequential conditioning model. This approach balances myeloablative intensity and immunomodulation, creating a favorable environment for subsequent long-term cord blood engraftment. III. Engraftment Outcomes and Clinical Value Preliminary clinical experience demonstrates that haplo-cord sequential transplantation following the FA5Cy2Bu3 conditioning regimen combined with low-dose ATG/PTCY can achieve long-term cord blood engraftment in approximately 50% of patients. By comparison, other domestic protocols (e.g., the Suzhou Protocol) rarely result in sustained cord blood engraftment. Achievement of long-term cord blood engraftment is clinically meaningful for reducing relapse rates, lowering the incidence and severity of graft-versus-host disease (GVHD), and improving patient prognosis. These outcomes represent a key advantage of the present protocol.

Parkinson's disease (PD) is a common neurodegenerative disorder in middle-aged and elderly individuals, with a global incidence of 2.0% among adults aged 65 and over. Its pathogenesis remains unclear, and effective preventive and therapeutic approaches are lacking. PD severely impairs patients' physical and mental health and quality of life, while also imposing a substantial burden on families and society. This study will enroll patients with idiopathic PD diagnosed in the Department of Neurology, Fujian Medical University Union Hospital, from 2026 to 2036 to establish a research cohort. Using a non-interventional design, participants will undergo long-term follow-up through regular clinical visits, scale-based assessments, imaging examinations, and biological specimen testing. Corresponding data will be collected to build a research platform, aiming to clarify the pattern of disease progression and identify early diagnostic biomarkers. All testing methods are safe and reliable and will not pose additional risks to patients. This study will be conducted in strict compliance with ethical requirements. Prior to enrollment, patients will be fully informed of the study details and will voluntarily provide written informed consent. To mitigate the risk of privacy disclosure, measures including coded management, data encryption, and access restriction will be implemented throughout the study to protect participants' privacy, safeguard their legitimate rights and interests, avoid additional financial burdens, and ensure the study is conducted in a standardized manner. I hereby pledge to protect the personal privacy of all study participants and respect their autonomy. The study will be conducted in accordance with the principles of the Declaration of Helsinki and the Ethical Review Measures for Life Sciences and Medical Research Involving Human Subjects.

Chemoresistance in acute myeloid leukemia (AML) is closely associated with the bone marrow microenvironment. Elevated levels of IL-6, leptin, fumarate, and other factors within the bone marrow microenvironment have been shown to enhance oxidative phosphorylation or antioxidant capacity in AML cells, thereby inducing chemoresistance. To explore their potential as prognostic biomarkers or therapeutic targets, this study plans to enroll 405 newly diagnosed AML patients meeting the criteria of the Chinese Guidelines for the Diagnosis and Treatment of Adult Acute Myeloid Leukemia (2023 Edition), along with 81 sex- and age-matched healthy controls. By analyzing the levels of IL-6, leptin, fumarate, and other factors in patient bone marrow supernatant, we will evaluate their associations with treatment response (primary endpoints: overall survival \[OS\] and overall response rate \[ORR\] after one cycle of chemotherapy) and prognosis. Furthermore, patient-derived xenograft (PDX) mouse models established from primary AML cells will be used to validate their roles in chemoresistance, aiming to provide a basis for therapies targeting the bone marrow microenvironment.

Silibinin is the major active component of silymarin, a commonly used hepatoprotective agent. It stabilizes hepatocyte membranes, preserves cellular integrity, and accelerates DNA synthesis in liver cells. Clinically, it is widely used in the treatment of chronic persistent hepatitis, chronic active hepatitis, early-stage liver cirrhosis, and hepatotoxicity. Moreover, it has been reported to inhibit the growth and differentiation of various cancer cells, including hepatocellular carcinoma, prostate cancer, breast cancer, and cervical cancer. Based on these preclinical findings, we aim to evaluate the efficacy and safety of combining silybinin with the standard first-line idarubicin/daunorubicin-based regimen in the treatment of newly diagnosed acute leukemia(non-M3)in a clinical setting.

Acute myeloid leukemia (AML) is the most common acute leukemia in adults. While approximately 70% of patients achieve complete remission (CR) with induction chemotherapy, traditional consolidation therapy (predominantly high-dose cytarabine) has a persistently high recurrence rate - nearly 30% at 1 year for low-risk groups and 80% for high-risk groups - with a long-term survival rate \<40%. Allogeneic hematopoietic stem cell transplantation (allo-HSCT) improves survival but is limited by donor matching and patient tolerance, resulting in a transplantation rate \<20%. Clinically, there is an urgent need for a well-tolerated, low hepatotoxic/nephrotoxic maintenance regimen effective for preventing recurrence. Tumor immunotherapy is a major breakthrough, and neoantigen-based personalized vaccines are a key anti-recurrence direction due to their strong tumor specificity and ability to induce long-term immune memory. However, existing neoantigen vaccines rely on NGS sequencing and bioinformatics for epitope screening, suffering from long development cycles, high costs, proneness to missing cancer-causing mutations, and poor clinical feasibility, hindering widespread use. This study adopts a patented Sino-US innovative technology: in vitro induction of patients' own AML cells to obtain a complete set of tumor antigen peptides for personalized vaccine preparation, circumventing traditional bottlenecks to achieve "full antigen coverage" personalized active immunity. This study has significant clinical and scientific value: (1) It is the first application of this patented technology in AML maintenance therapy, filling domestic and international research gaps and providing a novel treatment option; (2) Using a randomized controlled design, it compares the efficacy of immunotherapy administered during vs. after consolidation chemotherapy to identify the optimal treatment mode; (3) It screens reliable anti-leukemia immunity monitoring methods and time points, offering evidence-based support for efficacy evaluation and prognostic prediction; (4) It verifies the treatment's safety, laying a foundation for developing low-toxic, high-efficacy AML maintenance regimens, ultimately improving patients' long-term survival and advancing precision immunotherapy for AML.

The goal of this clinical trial is to learn if Rezvilutamide works to treat high-risk prostate cancer in patients who have recently undergone surgery (radical prostatectomy). It will also learn about the safety of Rezvilutamide. The main questions it aims to answer are: Does Rezvilutamide, when used as an add-on treatment after surgery, lower the risk of the cancer returning (biochemical recurrence) within 3 years? What is the 36-month metastasis-free survival (MFS) rate for patients receiving this treatment? What is the safety profile of Rezvilutamide combined with ADT, specifically regarding the types, grades, and incidence of Treatment-Emergent Adverse Events (TEAEs), Serious Adverse Events (SAEs), Adverse Drug Reactions (ADRs), Adverse Events of Special Interest (AESIs), and rare adverse events? What are the exploratory findings regarding the status of immune cells after using Rezvilutamide? Researchers will evaluate the combination of Rezvilutamide and hormone therapy (ADT) to see if it helps keep patients cancer-free. Participants will: Take Rezvilutamide: 240 mg once daily, taken orally before or after breakfast. Each cycle is 28 days, for up to 24 cycles. Treatment continues unless biochemical recurrence, disease progression, intolerable toxicity occurs, or the participant withdraws consent, as determined by the investigator. Receive Androgen Deprivation Therapy (ADT): Leuprorelin 3.75mg via subcutaneous injection, once every 28 days for a total of 12 cycles.

The goal of this clinical trial is to learn whether the application of indocyanine green near-infrared imaging system can accurately locate the recurrent laryngeal nerve (RLN) during lymph node dissection in esophageal cancer radical surgery, thereby reducing the risk of RLN injury. The main questions it aims to answer are: 1. Can preoperative intravenous administration of indocyanine green enable visualization of the RLN; 2. Does performing RLN dissection guided by near-infrared imaging system reduce the probability of RLN injury, leading to better clearance of RLN lymph nodes and improved RLN protection rates? Researchers will compare whether indocyanine green was intravenously administered preoperatively to assess intraoperative RLN visualization. Participants in the study group will receive intravenous indocyanine green at a dose of 5mg/kg 24 hours before surgery. All patients will be monitored for RLN injury-related complications postoperatively, and RLN injury status will be objectively assessed via laryngoscopy one week post-operation.

Androgenic Alopecia(AGA) is a highly prevalent condition for which existing pharmacological and surgical interventions present limitations and side effects, creating a clinical need for safer and more effective therapies. In response, human umbilical cord mesenchymal stem cell-derived exosomes (hUCMSC-Exos) have emerged as a cell-free therapeutic strategy. Characterized by their rich bioactive components, absence of tumorigenic risk, and high safety profile, hUCMSC-Exos represent a promising approach for hair regeneration. This study aims to evaluate the safety and efficacy of hUCMSC-Exos combined with automated microneedle delivery for treating AGA. By utilizing innovative lyophilization technology to maintain exosomal bioactivity and employing precision microneedle systems for enhanced delivery, this research seeks to provide a new generation solution for androgenic alopecia treatment.

This study is grounded in the regulatory mechanisms of the glymphatic system and applies repetitive transcranial magnetic stimulation (rTMS) to the treatment of Alzheimer's disease (AD). The clinical efficacy and safety of rTMS will be systematically evaluated. Furthermore, transcranial magnetic stimulation-evoked potentials (TMS-EEG) and functional near-infrared spectroscopy (fNIRS) will be employed to investigate, from the perspectives of synaptic plasticity and neurovascular coupling, the mechanisms by which rTMS influences glymphatic function. Collectively, this work aims to provide new insights into both the therapeutic effectiveness and the underlying mechanisms of rTMS in AD.

Sentinel lymph nodes, as the primary site of tumor metastasis, play a pivotal role in assessing patient prognosis and planning subsequent treatment strategies. The investigators plan to conduct a multicenter, prospective cohort study to evaluate the effectiveness of indocyanine green (ICG)-guided near-infrared imaging in tracing sentinel lymph node during esophageal squamous cell carcinoma (ESCC) surgery, compared with the gold standard of complete lymph node dissection (CLND), in detecting metastatic disease. This study aims to address the following core questions: 1. In ESCC patients undergoing surgery, can sentinel lymph node biopsy reduce unnecessary lymph node dissection? 2. In ESCC patients undergoing surgery, can reducing lymph node dissection decrease postoperative complications such as chylothorax and weakened immunity? During the study, ICG will be injected around the tumor under intraoperative gastroscopy guidance, followed by tracking of fluorescent lymph nodes using a thoracoscopic near-infrared camera. Professional thoracic surgeons will group and mark these lymph nodes for intraoperative frozen pathology. Subsequent CLND and routine postoperative pathology will be performed. This study will collect patients' clinical information, ICG imaging results, pathological examination results, and other data for statistical analysis to assess the sensitivity and negative predictive value (NPV) of the ICG imaging system. If the study results support the effectiveness of the ICG imaging system, it has the potential to become an important tool for sentinel lymph node localization and biopsy in future ESCC surgeries, helping to reduce unnecessary lymph node resection and improve surgical efficiency and safety. Participants will: 1. Undergo minimally invasive ESCC surgery within 2 weeks of enrollment, including the 14th day. 2. Receive ICG injection around the tumor under intraoperative gastroscopy guidance during surgery. 3. Have perioperative, postoperative pathology, and complication information recorded. 4. Undergo standardized follow-up after surgery.

Targeted biopsy combined systematic biopsy is the gold standard for diagnosis of prostate cancer. Excessive cores in systematic biopsy increases the risk of puncture trauma， bleeding and infection. On the basis of establishing a model with DRS stratification to reduce the cores of systematic biopsy, we propose the (12 cores -x) model innovatively. We hope that through this prospective study to verify the efficacy of the model and provide patients with a new biopsy model with high accuracy and fewer complications. In this study， patients with suspected prostate cancer were randomly divided into two groups. Experimental group received targeted biopsy combined personalized systematic biopsy, and the control group received systematic biopsy .The differences of the detection rate of Prostate cancer between the two groups were compared.

This is a multicenter, open-label, prospective, single-arm, phase II study designed to evaluate the efficacy and safety of neoadjuvant zanidatamab combined with tislelizumab and chemotherapy, followed by selective bladder preservation, in patients with HER2-positive muscle-invasive bladder cancer (MIBC) staged cT2-4aN0-1M0.

This study aims to systematically evaluate the effects of different anesthesia methods on postoperative chronic cough in lung cancer patients undergoing video-assisted thoracoscopic lung resection (VATS), and to clarify the effectiveness and safety of each anesthesia airway management strategy in reducing the incidence of postoperative chronic cough, shortening the duration of cough, alleviating the severity of symptoms, and improving the postoperative quality of life of patients.

This study aims to evaluate the impact of the neoadjuvant treatment strategy based on CPS score on the pathological complete response (pCR) rate in patients with resectable locally advanced esophageal cancer.

Acute Myeloid Leukemia (AML) is a malignant clonal disorder of hematopoietic stem/progenitor cells, with a five-year survival rate of approximately 30%. Chemotherapy resistance and relapse remain major challenges. Increased bone marrow adipocytes contribute to AML cell drug resistance.This study found that elevated levels of the adipokine leptin enhance oxidative phosphorylation (OXPHOS) in AML cells, accompanied by increased mitochondrial reactive oxygen species (mtROS), which stimulates antioxidant capacity and thereby induces chemotherapy resistance. By establishing a correlation between leptin levels in bone marrow supernatant and clinical outcomes in AML patients, this research provides novel strategic insights for targeting drug resistance and improving prognostic evaluation.

The incidence of chest CT manifestations of lung injury after radiotherapy for breast cancer is more than 50%. Although the prognosis and quality of life of patients are rarely affected, it is still necessary to prevent the occurrence of minor radiation lung injury with the use of more novel drugs and subsequent salvage treatment may aggravate the radiation injury. This study intends to conduct a randomized, double-blind, single-center clinical study of pirfenidone versus placebo in the prevention of acute radiation induced lung injury after breast cancer surgery

Melasma is a refractory skin disease due to its complex pathogenesis and difficult treatment. Studies have found that human umbilical cord mesenchymal stem cell-derived exosomes (hUCMSC-Exos) could serve as a novel cell-free therapeutic strategy in regenerative and aesthetic medicine. It could potentially treat melasma, but the skin barrier is a challenge. This study aims to explore the safety and efficacy of hUCMSC-Exos in the treatment of melasma and means to promote its percutaneous penetration.

The goal of this clinical trial is to evaluate the safety and effectiveness of human umbilical cord mesenchymal stem cell (hUCMSC) therapy in patients undergoing medium-thickness skin grafts for donor site wounds. The study aims to answer the following main questions: * Question 1: Does hUCMSC therapy improve the healing quality and speed of donor site wounds in comparison to standard treatment? * Question 2: Does hUCMSC therapy reduce scar formation in the donor site wounds? Participants in this study will undergo medium-thickness skin grafts, and those in the treatment group will receive hUCMSC therapy. The main tasks for participants will involve regular follow-up visits, monitoring of wound healing progress, and assessment of any potential side effects or complications associated with the therapy. In order to evaluate the effectiveness of hUCMSC therapy, researchers will compare the treatment group receiving hUCMSC therapy with a control group that receives standard treatment alone. The aim is to determine if the use of hUCMSC therapy leads to improved healing outcomes and reduced scar formation compared to the standard treatment group.
