Clinical trials

Idiopathic epiretinal membrane is a condition in which abnormal tissue grows on the surface of the retina and can cause blurred vision and distortion. The standard surgical treatment is removal of this membrane, but some patients may not achieve complete visual recovery because the normal structure of the central retina may not fully restore after surgery. This study is a prospective randomized controlled trial designed to evaluate a new surgical technique called macular resurfacing using an autologous internal limiting membrane patch transposition. The technique uses a patient's own retinal tissue to cover the macular area after epiretinal membrane removal, with the aim of promoting more natural healing of the retinal surface. Patients with idiopathic epiretinal membrane will be randomly assigned to receive either the new surgical technique or conventional epiretinal membrane peeling. Visual function and retinal structural changes will be evaluated using visual examinations and multimodal retinal imaging during follow-up. The study aims to determine whether this new technique can improve visual outcomes and promote better restoration of macular microstructure.

Using liver biopsy as the gold standard, this study will conduct visual transient elastography (ViTE) examinations using Mindray Hepatus 9 ultrasound diagnostic system in patients with liver injury to evaluate the diagnostic efficacy of Liver Steatosis Analysis (LiSA) and ViTE for grading hepatic steatosis and fibrosis, and establish corresponding diagnostic thresholds.

The purpose of this research is to develop a body voice artificial intelligence (AI) recognition device, also referred to as an AI-assisted body sound identification device, by utilizing a deep learning-based novel AI algorithm in conjunction with a big body voice model. It could identify normal and abnormal heart, breath, and bowel sounds, and to provide early screening and auxiliary diagnosis of congenital heart disease (CHD), respiratory infections, diarrhea and other common multi-occurring diseases.

The goal of this observational study is to develop and validate a multimodal artificial intelligence prediction model for treatment-related complications in children with perimembranous ventricular septal defect (pmVSD) undergoing transcatheter device closure. The main question it aims to answer is: Can an AI model that integrates demographics, laboratory results, electronic health record text, echocardiography reports, chest radiographs, and electrocardiogram accurately predict the risk of complications at the individual patient level? Data will be retrospectively collected from routine clinical care records of pediatric patients who underwent transcatheter closure for pmVSD. Deep learning methods will be used to extract features from text and images to train and validate the prediction model.

This project addresses the challenge of visual function intervention in children with monocular anisometropic amblyopia. It employs two innovatively designed digital games combined with occlusion therapy to conduct visual function training through parent-child interaction in home or multi-scenario environments. The study will compare this combined approach against traditional occlusion therapy alone, evaluating improvements in visual function, intrinsic motivation, and emotion regulation before and after the intervention. The research aims to promote the implementation and dissemination of personalized and engaging healthcare services. Ultimately, it seeks to establish a comprehensive visual function training product and service system suitable for daily use in home settings, with the goals of reducing medical anxiety in children and holistically enhancing treatment efficacy, training compliance, and overall clinical experience.

Infectious uveitis is a very important blinding disease. Some people who have been diagnosed with idiopathic uveitis may also have the activity of pathogens in the eye. However, due to the limitation of the amount of ocular samples, it is difficult to make a rapid and effective diagnosis of infection.Current study is to explore the infective cause of uveitis in China by using a broad diagnostic approach of detection.

This study aims to observe the difference between NMAP (nicotinamide metabolism associated protein) serum levels in primary diagnosed renal cancer patients and non-renal cancer patient controls, plot the ROC curve and establish appropriate cut-off values.

GnRH-a will be used to postpone period after vaginal repair for Cesarean Section Scar Defect（CSD） patients with adenomyosis which will be compared with CSD patients with adenomyosis who receive transvaginal surgery without GnRH-a, whether delayed period improving the CSD prognosis will be assessed.

Cesarean section scar defect (CSD) is a novel recognized cause of postmenstrual abnormal uterine bleeding in women. No clinical guidelines have been issued for the management of CSD. The investigators have previously demonstrated that vaginal repair of CSD was an relative effective treatment of CSD. However, only 28.2% of the CSD patients normalized to less than 7 days of menstruation, whereas 51.2% of women had 7 to 10 days of menstruation at 6 months post vaginal repair. The previous research suggested that the occurrence of CSD may be related to the aging phenotype of the myometrium. Metformin, as a classic diabetes treatment drug, has an important position in anti-aging therapy. Therefore, the randomized study was designed to evaluate whether the application of metformin in combination with vaginal repair could achieve better clinical effects than those achieved by vaginal CSD repair alone.

This study is a prospective observational clinical trial. Patients who were diagnosed and treated for the first time were enrolled and their surgical pathology was confirmed to be high-grade serous ovarian cancer. At the same time, these patients will receive first-line maintenance treatment with PARP inhibitors after traditional chemotherapy. During the trial period, patients' plasma will be collected before surgery, after chemotherapy, during targeted maintenance therapy, and during disease progression, and ctDNA-specific genomes will be detected, and clinical data will be collected over the same period. It is expected that specific ctDNA can be used to predict the efficacy of PARP inhibitors in patients with ovarian cancer, and to detect the recurrence of the disease early.

Osteoarthritis (OA) of knee is the most common form of arthritis in the world1e, and it has received growing attention in the society because of the increase of old age population, disabled people, and medical expenses from this disease. 99Tc-MDP is effective for rheumatoid arthritis. Therefore, the investigators try to investigate the effects of 99Tc-MDP treatment in patients with osteoarthritis of knee as compared with celecoxib.

Background Newborns perceive the world through sound, and music therapy in the neonatal intensive care unit has been shown to have significant benefits in terms of heart rate, oxygen saturation, sucking/feeding capacity, and length of hospital stay. However, it is still unclear what kind of music therapy can better promote early extrauterine growth in preterm infants, and further exploration and practice are needed. Music therapy is an emerging interdisciplinary discipline that integrates musicology, medicine, and psychology. In the uterine environment, the most important rhythmic sounds that the fetus can hear is the mother's heartbeat, as well as the fetus's own heartbeat. The maternal heart rate ranges from 60 to 100 beats/min, and the corresponding speed of 60-100 beats/min in music is medium speed. The fetal heart rate is 110-160 beats/min, and the corresponding speed of 110-160 beats/min in music is considered fast. Music slower than 40-50 beats/min is slow. The primary objective of this study is to investigate the effect of music therapy at different music speeds in preterm infants, at the time to full enteral feeding. Methods This is a single-center, randomized, open-label, parallel-controlled trial including 284 preterm newborns with gestational age or corrected gestational age ≥32 weeks admitted into the neonatal intensive care unit. The infants will be randomly allocated to receive music I, II, III or control therapy. The music therapy is provided with the same music in three different tempos: 40-50 beats/min, 60-100 beats/min, and 110-160 beats/min, by two professional licensed music therapists using the same instrument and singing, before morning and afternoon feeding time every day during hospitalization. The primary outcome is the time to achieving full enteral feeding. The secondary outcomes include sucking/feeding capacity, physical growth rate, complications, length of hospital stay, behavior state (Test of Infant Motor Performance (TIMP), Bayley III Infant Development Scale), and brain imaging (resting functional magnetic resonance imaging). Hypothesis: The investigator expect that either music therapy applied at 40-50 beats/min or 110-160 beats/min will result in early full enteral feeding, and reductions in length of hospital stay and complications in preterm infants.

The goal of this prospective cohort study is to enroll pregnancies complicated by placental-related fetal growth restriction (FGR) and to develop predictive models for adverse short- and long-term outcomes. This will be achieved by collecting novel intrauterine monitoring indicators along the fetal brain-placenta-heart axis, combined with conventional fetal surveillance parameters, in order to improve risk stratification and guide clinical management, ultimately improving pregnancy outcomes. The study will include pregnant women with singleton pregnancies complicated by isolated early-onset placental insufficiency-related FGR, preferably those with abnormal umbilical artery Doppler findings, who elect to continue the pregnancy. The main question it aims to answer is: • Whether a predictive model integrating novel intrauterine monitoring indicators along the fetal brain-placenta-heart axis with conventional monitoring parameters can accurately predict perinatal and neonatal adverse outcomes in pregnancies complicated by placental-related FGR.

Exacerbations of chronic obstructive pulmonary disease (COPD) are unfavourable events in the course of disease for most COPD patients. Published evidence indicates a significant impact of exacerbations, especially if frequent, on patients' health-related quality of life (HRQL), disease progression, mortality, health care utilisation and costs. However, the severity,evolution and outcome of an exacerbation may differ significantly between patients - some patients will recover completely in a short period of time while others may die. The identification of risk factors for an adverse outcome could help in distinguishing patients who require more intense management in order to prevent failures, achieve satisfactory recovery and reduce the negative clinical and socioeconomic impact of exacerbations.The pathogenesis of COPD is still unclear, so there is no specific treatment at present .COPD was considered to be the result of a combination of environmental and genetic factors. Genetic factors play an important role in the acute exacerbation of COPD.Therefore, it is an urgent need to explore the heterogeneity of COPD phenotype from the perspective of genes and to seek individualized prevention and treatment programs.This study is intended to provide a theoretical basis for the prevention, evaluation and development of individualized treatment plans for acute exacerbation of COPD, thereby improving the prognosis of the disease.

Given the significant and growing burden of Type 2 Diabetes (T2DM) in China, there is a continuous need for effective, convenient, and well-tolerated treatment strategies. This Phase IV, multicenter, prospective, observational study aims to evaluate the real-world effectiveness and safety of a novel, once-daily, fixed-dose combination (FDC) tablet containing Henagliflozin (SGLT2 inhibitor), Retagliptin (DPP-4 inhibitor), and Metformin Extended-Release in Chinese patients with T2DM. The study plans to enroll approximately 300 patients across 30 sites, stratified into two cohorts: newly diagnosed, drug-naïve patients and those with inadequate glycemic control on a single prior oral antidiabetic drug. The primary objective is to assess the change in Glycated Hemoglobin (HbA1c) from baseline after 24 weeks of treatment. Key secondary objectives include evaluating the proportion of patients achieving HbA1c targets (\<7.0% and ≤6.5%), assessing changes in other metabolic parameters such as body weight, blood pressure, fasting and postprandial glucose, and lipid profiles, and monitoring treatment adherence. The safety evaluation will comprehensively document all adverse events, with special attention to events of interest including hypoglycemia, urinary/genital infections, volume-related events, and diabetic ketoacidosis. The study design includes a screening period, a 2-week run-in with lifestyle intervention, a 24-week core treatment period where eligible patients receive the FDC therapy, and a final safety follow-up. Efficacy and safety assessments are scheduled at baseline, Week 4, Week 12, and Week 24. Statistical analysis will be primarily descriptive, focusing on changes from baseline for continuous endpoints and frequency distributions for categorical endpoints, with analyses conducted separately for the two patient cohorts. The study will be conducted in full compliance with Good Clinical Practice (GCP), the Declaration of Helsinki, and relevant Chinese regulations, requiring prior ethics committee approval and written informed consent from all participants. This real-world evidence study seeks to confirm the clinical benefits and safety profile of this triple-combination therapy observed in earlier controlled trials, providing practical insights into its use in routine management of T2DM within the Chinese healthcare context.

The main question\[s\] it aims to answer are: 1. Can AI modeling of CXR features help identify high-risk KD patients earlier than current diagnostic methods? 2. Can the AI system predict the optimal IVIG treatment window and coronary artery risks in KD patients? Participants will: Provide retrospective data on chest X-rays and clinical data (CRP, coronary ultrasound, etc.) Allow analysis of CXR features using deep learning models to extract relevant patterns Have their data incorporated into a federated learning model to ensure privacy and data security

This multicenter, randomized controlled clinical trial (FIRM02 Study) aims to evaluate the effectiveness and safety of neoadjuvant mFOLFOX6 chemotherapy combined with PD-1 inhibitor (Serplulimab) in patients with MSS/pMMR locally advanced rectal cancer (LARC). A total of 128 patients with non-metastatic, untreated, locally advanced rectal cancer will be randomly assigned in a 1:1 ratio to either the experimental group (64 patients) or the control group (64 patients). The experimental group will receive 6 cycles of mFOLFOX6 chemotherapy combined with 3 mg/kg of Serplulimab every 2 weeks prior to surgery. The control group will receive 6 cycles of mFOLFOX6 chemotherapy alone. The primary endpoint is the pathological complete response (pCR), and secondary endpoints include major pathological response (MPR), tumor regression grade (TRG), overall response rate (ORR), and survival outcomes (DFS, RFS, and OS). Safety will be assessed based on adverse events and post-operative complications.

The goal of this nationwide multicenter observational study is to comprehensively investigate the severity of Small Vulnerable Newborns (SVN) issues across China and to propose further preventive and intervention measures. The primary aim is to provide a thorough description of SVN problems using a unified definition and framework, and to develop targeted prevention strategies. Participating centers across the country will collect clinical data on vulnerable newborns under their care and complete detailed questionnaires to support this research.

Acute respiratory distress syndrome (ARDS) is a serious lung condition in which fluid builds up in the air sacs, making it hard to breathe and often requiring intensive care. Older adults fare worse because their lung-lining cells lose the ability to heal properly after injury This study will explore two key molecules-RSPO3 and Syndecan-1 (SDC-1)-that normally help alveolar (air-sac) cells regenerate. We will collect small blood samples from ARDS patients and, when patients undergo elective lung surgery, tiny pieces of healthy lung tissue. In the lab, we will also grow three-dimensional "lung organoids" from these samples to see how boosting or blocking RSPO3/SDC-1 affects cell repair Our goals are to: Measure RSPO3/SDC-1 activity alongside inflammatory markers (e.g., IL-6, TNF-α) to understand their roles in age-related repair failure. Build an integrated platform for early diagnosis, disease monitoring, and treatment evaluation in older ARDS patients. Identify molecular targets that could lead to new therapies, helping older adults recover lung function more effectively.

Obstructive sleep apnea-hypopnea syndrome (OSAS) is a common disorder in which repeated airway blockages during sleep lead to low oxygen levels, inflammation, and disrupted sleep. Many OSAS patients-both children and adults-experience problems with memory, attention, and mood, such as anxiety or depression. However, the exact molecular drivers of these brain changes are not fully understood. This observational study will enroll: Children (ages 2-18) and adults (\>18 years) with OSAS, as well as age- and sex-matched healthy volunteers. Clinical assessments: Children will undergo routine ENT examinations (including nasal endoscopy and X-rays); adults will have an overnight sleep study (polysomnography). All participants will complete questionnaires on sleepiness (e.g., ESS), mood (PHQ-9, GAD-7), and cognitive screening (MoCA for adults, age-appropriate scales for children). Sample collection: A small blood draw (3 mL) and, when applicable (e.g., adults undergoing surgery), a tiny subcutaneous fat biopsy. Saliva samples will also be collected. Laboratory tests: Measure expression levels of two key inflammatory pathway genes-EGR2 and NLRP3-in blood cells, saliva, and fat tissue using RNA sequencing, RT-qPCR, and Western Blot. Correlate these molecular markers with sleep parameters (AHI, oximetry), cognitive scores, and mood scores. Data analysis: Develop and validate machine-learning models that integrate data from multiple tissues to predict who is at highest risk for cognitive or mood disturbances.

The goal of this clinical trial is to learn if SGLT2 inhibitor Henggliflozin works to improve glucose variability in type 2 diabetes and if Henggliflozin can benefit immunosenescence. The main questions it aims to answer are: Does Henggliflozin as an add on treatment works to improve blood glucose fluctuation in type 2 diabetes? Does Henggliflozin has extra benefits like improve immunosenescence beyond hypoglycemic effects? Researchers will compare Henggliflozin to a placebo to see if Henggliflozin can improve glucose variability and immunosenescence. Participants will: Take Henggliflozin or a placebo every day for 16 weeks. Receive weekly follow-up calls to guide them in adjusting their insulin doses. Return for an on-site visit at 4 weeks and 16 weeks. Take a continuous glucose monitoring (CGM) for 7 days at the Visit 1 and at the end of the study.

This single-center, prospective cohort Study evaluates whether adding the pHA130 hemoperfusion cartridge to conventional hemodialysis (HD) or hemodiafiltration (HDF) more effectively reduces protein-bound uremic toxins-specifically indoxyl sulfate (IS) and p-cresyl sulfate (PCS)-in maintenance HD patients. Adults on thrice-weekly, 4-hour HD for at least three months are randomized to one of three arms: HD/HDF alone; HD/HDF plus biweekly pHA130 hemoperfusion; or HD/HDF plus biweekly HA130 hemoperfusion. After a four-week washout, toxin levels are measured at baseline and again at Weeks 4, 12, and 24, with the primary endpoint being the reduction in IS and PCS at Week 24. Secondary endpoints include single-session toxin removal, middle-molecule clearance (β₂-microglobulin, PTH), patient-reported outcomes (itching, sleep, quality of life), and rates of hospitalization and mortality. Safety is closely monitored through adverse event reporting and consistent anticoagulation dosing. Findings will clarify the clinical value of pHA130 hemoperfusion for improving toxin clearance and guiding optimal dialysis strategies.
