There are about 36818 clinical studies being (or have been) conducted in China. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
The investigators designed and synthesized a novel fibroblast activation protein (FAP) ligand (DOTA-GPFAPI-04) by assembling three functional moieties: a quinoline-based FAP inhibitor for specifically targeting FAP, a FAP substrate Gly-Pro as a linker for increasing the FAP protein interaction, and a 2,2',2",2‴-(1,4,7,10-tetraazacyclododecane-1,4,7,10-tetrayl)tetraacetic acid (DOTA) chelator for radiolabeling with different radionuclides. Molecular docking studies investigated the FAP targeting ability of DOTA-GPFAPI-04. DOTA-GPFAPI-04 was then radiolabeled with 68Ga to give 68Ga-DOTA-GPFAPI-04 for positron emission tomography (PET) imaging. The investigators found that the 68Ga-DOTA-GPFAPI-04 has high stability, targeted specificity, and longer retention time. The tumor-to-muscle (T/M) ratio for 68Ga-DOTA-GPFAPI-04 reached 9.15.
This is an open-label, multicenter phase 1 study to evaluate the safety, efficacy, and pharmacokinetics (PK) characteristics of SIM0237 alone or in combination with bacillus Calmette-Guerin (BCG) in participants with Non-Muscle-Invasive Bladder Cancer (NMIBC)
Neonatal hyperbilirubinemia ( NHB ) has many causes and is difficult to diagnose, and genetic factors play an important role in the metabolism of bilirubin. However, there is no literature report on the correlation between jaundice gene polymorphism and clinical manifestation polymorphism in big data population. This project intends to conduct a prospective observational study led by the Department of Pediatrics of the Sixth Affiliated Hospital of Sun Yat-sen University and in conjunction with a multi-center cooperative hospital : ( 1 ) A total of 2,000 NHB neonatal dry blood spot samples were included for 24 genetic screening tests for 29 NHB-related genetic diseases. The construction of the gene database was completed and the carrying and pathogenicity of NHB-related genes in the population was analyzed to provide a scientific basis for the selection of mutation sites for large-scale NHB gene screening ; ( 2 ) Collect neonatal clinical data and percutaneous bilirubin levels through the hospital inpatient system and the ' percutaneous jaundice meter home monitoring + software doctor-patient interconnection ' method, complete the construction of the intelligent NHB clinical database, and analyze the impact of jaundice-related genes on NHB ; ( 3 ) Integrated analysis to understand the differences in the carrying rate of pathogenic genes in different degrees and special types of jaundice, and to explore the differences in the degree of jaundice carrying single or multiple jaundice pathogenic genes. This study will evaluate the feasibility of jaundice gene screening program in the detection of jaundice-related inherited metabolic diseases, and provide a basis for early treatment and prevention of NHB.
Perioperative neurocognitive disorders is a common postoperative complication in elderly surgical patients. The role of gut microbiota in cognitive function has been concerned in recent years. Studies suggests that gastrointestinal surgery may affect the gut microbiota, and the effect varies between surgical procedures. In this study, the investigators will compare the differences of gut microbiota between total gastrectomy and double-tract reconstruction, to investigate the effect of gastric acid on the gut microbiota colonizing, and the effect of different surgical procedures on the postoperative cognitive function of proximal gastric cancer patients.
Aprospective, multicentre, single-arm clinical trial in which approximately 36 subjects would be enrolled using the Bridge 4.5 mm and 5.0 mm stent in accordance with the inclusion and exclusion criteria in this protocol. The success rate of immediate post-procedure stent target lesion treatment was recorded for all subjects, and the incidence of in-stent restenosis (≥50% stenosis) was assessed by DSA imaging follow-up at 6 months (±30 days) post-procedure. The subjects were also followed up at 30 days (±7 days), 6 months (±30 days), and 12 months (±60 days) after stent implantation to assess safety events during the follow-up period. .
The investigators plan to analyze the data of patients with gastric cancer (GC) consecutively hospitalized in Ruijin Hospital, a large tertiary center in China, comprehensively describe the characteristics of GC patients ≥65 years, and assesse their in-hospital outcomes regarding duration, fee, and death. Factors associated with the in-hospital outcomes will be further comprehensively explored.
Collect optical biological parameters, refractive index data, and other related parameters of myopia and refractive errors in children and adolescents, and establish an optical model of myopia in children and adolescents.
Recurrent acute pancreatitis (RAP) was defined as two or more occurrences of acute pancreatitis, which was associated with higher percentages of morbidities and mortalities, lower patients' life quality and increased health-care costs. Current interventions, including cholecystectomy and abstain from drinking were reported to be effective methods for preventing the recurrences of biliary and alcoholic etiologies, respectively. However, there were no effective preventions for other etiologies, such as idiopathic etiologies. Non-steroid anti-inflammatory drugs (NSAIDs), including indomethacin, diclofenac and aspirin could inhibiting the inflammatory cascade of pancreatitis. In this study, we aimed at exploring the effects of 100mg aspirin on reducing the occurrences of recurrent acute pancreatitis.
This was a randomized controlled study including 80 infants with cerebral palsy and dysphagia. The Participants were evenly divided into the observation group (with intermittent oro-esophageal tube feeding, n=40) and the control group (with persistent nasogastric tube feeding , n=40). Nutritional status and physical development, condition of dysphagia, and pneumonia before and after 3-month treatment were compared.
The goal of this prospective, multi-center, randomized, parallel-controlled, open-label clinical study is to evaluate the effectiveness and safety of Prontosan wound irrigation solution comparing with Normal Saline on the removal of wound bacterial biofilm through observing the morphological characteristics and development of bacterial biofilm in chronic wound patients with secondary infections. The main questions it aims to answer are: - Difference in scoring the positive rate of bacterial biofilm before the first treatment and on the 7th day of treatment in Group A and Group B - Difference in scoring the positive rate of bacterial biofilm before the first treatment and on the 3rd day of treatment in Group A and Group B . - Positive detection rate of bacterial biofilm in group and group B before the first treatment, and on the 3rd and 7th day of treatment, and difference of the positive detection rate of biofilm among the two groups. - 4-phase typing of bacterial biofilm detected in Group A, Group B and Group C before the first treatment, and on the 3rd and 7th day of treatment, and the proportion difference of 4-phase typing of biofilm among the two groups. - Wound healing rate - Skin Infection Rating Scale (SIRS) score. - Distribution of inflammatory cells on the wound. - Detection rate of bacteria/drug-resistant bacteria on the wound and their correlation with the detection rate of bacterial biofilm. Participants will be randomized to experimental group or Control group, Prontosan Wound Irrigation Solution or normal saline will be extracted with syringe (Dosage 1-2ml/cm2), and the wound is rinsed 1 cm from the wound. Then, Prontosan wound irrigation solution or normal saline is used to saturate the gauze, and the gauze is applied to the wound for 15 minutes. After removing the gauze, cover it with oil gauze, then cover it with 8 layers of gauze and wrap it with a bandage.
