Clinical trials

This study utilizes a multi-omics approach to systematically characterize the cellular heterogeneity and spatial architecture of the hair follicle microenvironment in patients with androgenetic alopecia (AGA). Our primary aim is to elucidate the key mechanisms driving hair follicle stem cell (HFSC) exhaustion and to identify potential therapeutic targets. Investigators will collect six groups of scalp tissue samples, which include healthy controls and AGA patients (stratified into younger and older cohorts). By integrating spatial transcriptomics, single - cell sequencing data, investigators will map aberrant cell subpopulations and their complex interaction networks. Furthermore, the identified core targets will be functionally validated using patient-derived organoids and animal models. Expected outcomes include the identification of 3-5 critical cell subpopulations and the discovery of 8-10 disease-associated targets. Additionally, investigators will establish an integrated clinical-omics-validation database, providing a robust theoretical foundation for the precision diagnosis and treatment of AGA.

This study tests a new nasal spray for adults (18-65 years) with chronic rhinosinusitis (CRS) without nasal polyps. The spray contains a temperature-sensitive gel (thermosensitive gel) that turns into a soft gel inside the nose to slowly release three active ingredients: human umbilical cord mesenchymal stem cell exosomes (hUC-MSC-Exo) to help heal the nasal lining, mupirocin (an antibiotic that kills Staphylococcus aureus bacteria), and DNase I (an enzyme that breaks down thick mucus). The study aims to check the safety of this triple combination and see if it can reduce infection, clear mucus, and improve symptoms. Participants will be randomly assigned to one of three groups: triple spray, a dual spray (without exosomes), or a placebo (gel only). The treatment is used twice daily for 4 weeks, with follow-up visits up to day 90. The study is single-centre, double-blind, and placebo-controlled. Outcome measures include safety (adverse events graded by Common Terminology Criteria for Adverse Events version 5.0, CTCAE v5.0), bacterial clearance rate, changes in nasal endoscopy score (Lund-Kennedy), quality of life (Sino-Nasal Outcome Test-22, SNOT-22), and nasal symptom visual analog scale (VAS).

This study tests a new nasal spray for adults (18-65 years) with chronic sinusitis experiencing an acute phase. The spray contains a temperature-sensitive gel that turns into a soft gel inside the nose to slowly release three active ingredients: stem cell exosomes (to repair nasal lining), azelastine (an antihistamine and anti-inflammatory drug), and interferon alpha-2b (an antiviral agent). The study aims to evaluate safety and see if the spray can reduce symptoms, fight viruses, and improve quality of life. Participants will be randomly assigned to one of three groups: triple spray, dual spray (without exosomes), or placebo (gel only). Treatment is twice daily for 4 weeks, with follow-up visits up to day 90.

This study aims to construct and systematically evaluate a multifunctional synergistic drug delivery system based on a hyaluronic acid-nanoclay composite hydrogel to achieve integrated treatment of periodontitis encompassing "infection control, inflammation regulation, and bone regeneration promotion." Through material design, in vitro functional validation, and in vivo efficacy evaluation, the study will elucidate the intrinsic relationships and synergistic mechanisms among "material structure, controlled drug release, and biological effects" within this system, thereby providing a theoretical basis and experimental foundation for the development of smart periodontal regenerative materials with clinical translational potential.

This project aims to construct an injectable self-healing hydrogel loaded with BMP-2, with optimized gelation time and mechanical strength to meet the requirements for periodontal pocket filling, for the treatment of periodontitis and acceleration of tissue repair, achieving a "bactericidal-anti-inflammatory-regenerative" trinity function. This project will provide a novel intelligent material for promoting alveolar bone regeneration in periodontitis and establish a theoretical paradigm for the precise intervention of oral infectious diseases.

Burn patients were randomly divided into the low-dose stem cell gel group, the high-dose stem cell gel group, and the placebo group (with only the gel), and received the same treatment under the same conditions simultaneously.

Based on the mechanism of intramembranous ossification of the alveolar bone, it is necessary to design a biomimetic membrane material based on the principle of GBR (Guided Bone Regeneration) to simulate the biological microenvironment of alveolar bone regeneration, promote the direct differentiation of stem cells into osteoblasts and rapid mineralization, thereby achieving the goal of alveolar bone regeneration. This section, based on bionic principles, proposes to enhance the mechanical properties of the collagen membrane with silk fibroin to achieve synergistic regeneration of periodontal bone/soft tissue. This project employs silk fibroin-reinforced collagen membrane technology to overcome the dual bottlenecks of insufficient strength and excessively rapid degradation of existing materials; establishes a "structure-guided, mechanically supported, factor-controlled release" trinity regeneration strategy to achieve precise repair of periodontal composite tissues. This study will provide new materials and methods for periodontal regeneration and offer a theoretical reference for the combined regeneration of other hard/soft tissues.

The overall objective of this study is to evaluate the safety and efficacy of allogeneic human dental pulp stem cells (DPSCs) injected for the treatment of chronic periodontitis in humans. It aims to develop a stem cell injection therapy that promotes the regeneration of periodontal soft and hard tissues through a non-invasive (minimally invasive) procedure, thereby replacing traditional traumatic periodontal surgery.

Osteonecrosis of the femoral head (ONFH) presents a rapidly progressive natural disease course. Femoral head collapse may occur within two years, ultimately necessitating total hip arthroplasty and imposing a heavy medical and economic burden on patients. Early intervention can significantly improve the long-term prognosis of ONFH. However, due to the lack of validated biomarkers for early diagnosis, the early diagnostic rate remains low, with a primary diagnostic rate of merely 68.43% at the first visit, accompanied by a high rate of misdiagnosis. This project intends to collect blood samples from patients diagnosed with ONFH and suspected cases in the orthopedic outpatient department of a tertiary Grade A hospital. Diagnostic and differential diagnostic tests will be adopted to evaluate the clinical application value of previously reported candidate biomarkers, so as to screen out biomarkers with excellent diagnostic validity and reliability. Meanwhile, clinical data will be collected to identify independent risk factors, and a multi-dimensional integrated diagnostic model will be further established. The research findings are expected to provide solid data support, theoretical basis and technical reserves for the early prevention, early diagnosis and individualized intervention of osteonecrosis of the femoral head.

Osteoarthritis (OA) is the most prevalent degenerative joint disease worldwide, which causes pain, loss of joint function and declined quality of life, and ranks as the leading cause of disability among individuals aged over 60 years. In China, the number of patients with osteoarthritis is projected to exceed 200 million by 2044, resulting in a continuously growing demand for medical resources and escalating economic burden.Nevertheless, the lack of effective biomarkers for early diagnosis leads to advanced disease conditions at the time of initial medical consultation and delayed treatment. This project intends to collect blood samples from OA patients and suspected patients in the orthopedic outpatient department of a tertiary hospital. Diagnostic and differential diagnostic tests will be adopted to verify the clinical application value of previously reported candidate biomarkers, so as to screen out biomarkers with favorable validity and reliability. The research findings are expected to provide data support and theoretical basis for the early prevention, early diagnosis and individualized intervention of osteoarthritis.

Melasma is a common pigmentation disorder among young and middle-aged women, characterized by symmetrical brown-black patches on the face. It is related to genetics, ultraviolet radiation, endocrine factors and inflammation, and can lead to psychological problems and affect quality of life. Current treatments such as hydroquinone stimulation, laser therapy, and oral tranexamic acid have a high recurrence rate and poor compliance. The new gel formulation, which combines tranexamic acid (to inhibit tyrosinase), aloe polysaccharides (anti-inflammatory and repair), and lauric azon (promotes penetration), is expected to enhance efficacy and reduce side effects. This study aims to explore its clinical efficacy and synergistic mechanism, providing new strategies for the treatment of Melasma.

Identifying and validating molecular biomarkers associated with tumor-related anxiety and depression. By integrating psychological assessment data from clinical tumor patients with molecular detection results, and utilizing clinically accessible samples such as tumor tissues and sera from clinical cohorts, this study aims to clinically validate the tumor-derived proteins previously identified by our team as having potential regulatory roles. The goal is to clarify the clinical value of tumor-derived proteins as molecular biomarkers for tumor-related anxiety and depression, providing a molecular basis for early screening and risk stratification. Alternatively, it seeks to establish a tumor-related anxiety and depression risk assessment model based on the expression levels of tumor-derived proteins, offering a reference for the precise identification and targeted intervention of psychological disorders in tumor patients.

Background: Endoscopic retrograde cholangiopancreatography (ERCP) is a key technique for treating pancreatobiliary diseases in the elderly. However, traditional sedative and analgesic regimens (e.g., sufentanil combined with propofol) are associated with a high incidence of respiratory depression, postoperative nausea and vomiting (PONV), and delayed recovery in elderly patients. Anricofen is a novel peripherally selective κ-opioid receptor agonist that provides analgesia with minimal central respiratory depression. Ciprofol is a new sedative agent characterized by rapid onset and quick recovery. The combination of these two drugs may offer a safer sedation and analgesia regimen for elderly patients undergoing ERCP. Objective: To evaluate the efficacy and safety of anricofen combined with ciprofol for deep sedation in elderly patients undergoing ERCP, compared with the traditional regimen (sufentanil combined with ciprofol). Methods: This is a single-center, randomized, double-blind, controlled trial. A total of 141 elderly patients aged 60-90 years with ASA physical status II-III scheduled for elective ERCP will be enrolled and randomly assigned in a 1:1:1 ratio to three groups: Anricofen 0.3 μg/kg + Ciprofol 1.0 mg/kg, Anricofen 0.5 μg/kg + Ciprofol 1.0 mg/kg, or Sufentanil 0.1 μg/kg + Ciprofol 1.0 mg/kg. The primary efficacy endpoint is the intraoperative pain control success rate (proportion of time with Behavioral Pain Scale \[BPS\] score ≤3 ≥90%). The primary safety endpoint is the incidence of respiratory depression (respiratory rate \<10 breaths/min or SpO₂ \<90% requiring intervention). Secondary outcomes include sedation depth, body movement episodes, recovery time, PONV incidence, and others. Significance: This study aims to provide a sedation and analgesia regimen with lower risk of respiratory depression and faster recovery for elderly patients undergoing ERCP.

This study aims to evaluate the lung-protective effects of ultrasound-guided lung recruitment maneuvers in patients with OSA undergoing total laparoscopic hysterectomy and to explore the efficacy of EELV measurement in assessing the effectiveness of these maneuvers.

Title: A Clinical Study Comparing Two Anesthesia Methods for Chest Surgery Why is this study being done? Chest surgeries (like lung surgery) require safe and stable anesthesia. Currently, a drug called propofol combined with an opioid painkiller (alfentanil) is commonly used. However, propofol can sometimes cause low blood pressure and low oxygen levels. A newer drug called remimazolam may cause fewer of these side effects. This study aims to compare the safety and effectiveness of remimazolam (combined with alfentanil) versus propofol (combined with alfentanil) for anesthesia during chest surgery. What will happen in the study? Patients scheduled for elective chest surgery will be invited to participate. If they agree, they will be randomly assigned (like flipping a coin) to one of two groups: * Group 1: Will receive remimazolam and alfentanil for anesthesia. * Group 2: Will receive propofol and alfentanil for anesthesia (standard care). The anesthesiologist will carefully monitor patients during and after surgery. We will mainly compare how often patients in each group experience two safety issues: low oxygen levels in the blood and low blood pressure. We will also record recovery times, drug doses, side effects, and ask patients and surgeons about their satisfaction. Who can participate? Adults aged 18-65 who are scheduled for elective chest surgery and are in relatively stable health (ASA physical status I-III). Where is the study taking place? This study will be conducted in the Department of Anesthesiology at The First Affiliated Hospital of Xinxiang Medical College, Henan, China. Ethics Approval: This study has been reviewed and approved by the Ethics Committee of The First Affiliated Hospital of Xinxiang Medical College (Approval Number: (2025) Medical Ethics Committee Approval No. 29).

This is a clinical study for patients with advanced solid tumors who have limited or no effective treatment options available. The study aims to evaluate a new investigational drug called VSV-02 Injection, which is developed by Shanghai Rongrui Pharmaceutical Technology Co., Ltd. The main purpose of this open-label, single-arm study is to assess the preliminary effectiveness and safety of VSV-02 when it is given through two routes: directly into a vein (intravenously) and by injection directly into the tumor (intratumorally). Patients will receive the treatment on the first day of each 3-week cycle, for up to 6 cycles. The study will follow a dose-escalation design to find a suitable dose. Treatment may be stopped if the disease progresses, if side effects become intolerable, or if the patient chooses to withdraw, among other reasons. Researchers will closely monitor patients to see if VSV-02 can help control the cancer and to record any side effects that may occur.
