There are about 35612 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.
Metabolic bone disease of prematurity (MBDP) is caused by insufficient content of calcium, phosphorus, and organic protein matrix in preterm infants or bone metabolism disorder, which is one of the complications affecting the quality of life of preterm infants. The early symptoms of MBDP are insidious, and there is no unified and clear diagnostic method. The diagnosis is mostly based on typical clinical manifestations and X-ray findings, but at this time, bone mineral density has decreased significantly, so early detection and diagnosis are difficult. Studies have shown that exosomal micrornas have biological characteristics and targeting specificity, and can be used as new molecular diagnostic markers for diseases. Several studies have reported the use of plasma or serum microRNAs as molecular markers for early prediction of bone diseases. In our previous study, we extracted plasma exosomes from preterm infants for high-throughput sequencing of microRNAs, and identified differentially expressed micrornas related to bone metabolism. In this study, exosomes were used as carriers, and digital PCR was used to verify the specificity and sensitivity of plasma exosomal microRNA as biomarkers of MBDP in a large sample size. The above biomarkers were compared and verified before and after treatment in children with MBDP. Further revealing plasma exosomal microRNA as a biological indicator for evaluating the efficacy of MBDP may improve the diagnostic level of MBDP, improve the outcome and prognosis of very low birth weight preterm infants, thereby improving global health and reducing socioeconomic costs.
The goal of this clinical trial is to learn the effect of neoadjuvant chemotherapy plus sequential immune checkpoint inhibitor (ICI) therapy in locally advanced colon cancer. The main questions it aims to answer are: - Does this neoadjuvant chemotherapy increase the pathologic complete response (pCR) of locally advanced colon cancer? - Does this neoadjuvant chemotherapy improve the long-term survival of locally advanced colon cancer? Participants will receive: - a pre-operative CAPEOX (capecitabine oral + oxaliplatin i.v.)regimen. - a sequential CAPEOX plus Serplulimab regimen. - a standard complete mesocolic excision (CME) operation.
This study is a prospective, single-center, single-group design exploratory clinical research. No control group is set, and only subjects meeting the indications of the study device are treated. After patients sign informed consent, they are screened, and those meeting the inclusion criteria are enrolled. The treatment involves using myocardial radiofrequency ablation system and catheter-based myocardial radiofrequency ablation needle and its guidance system for treating obstructive hypertrophic cardiomyopathy. All subjects are followed up before discharge, and at 30 days, 3 months, 6 months, and 12 months postoperatively.
1. We collect lung tissues from patients with different ages and confirm that KLK8 expression is positively correlated with age. 2. We collect peripheral blood from patients with different ages and duration of mechanical ventilation to explore the correlation between the degree of endothelial/epithelial damage, age and duration of mechanical ventilation.
This is a phase 1, first-in-human (FIH), open-label, multicohort study to evaluate the safety, tolerability and preliminary efficacy of CLL1 or CD33 target CAR iPSC NK cells in patients with relapsed/refractory AML
This project is a cross-sectional study. We plan to search and collect 1600 publicly published fecal metagenomic and metatranscriptome data through the Pubmed database, by summarizing and analyzing them to construct an enterovirus database. 200 apparently healthy individuals are planned to be enrolled. At the time of enrollment, fecal specimens of them will be collected, and their demographic characteristics, disease and medication history, gastrointestinal status, dietary habits, lifestyle habits, and mental health information will be recorded. Another 200 specimens will be collected from patients with parenteral virus infection. The demographic characteristics and pathogen test results of the parenteral virus infected patients will be reviewed and recorded. By virus metagenomic sequencing on fecal specimens, we will identify which viruses can be detected in the intestinal tract of apparently healthy people, and to explore whether parenteral infection viruses can be detected in feces.
This is a prospective, multi-center, randomized, controlled, subject- and evaluator-blinded clinical investigation to demonstrate non-inferiority of TEOSYAL® PureSense ULTRA DEEP compared to Restylane® Lidocaine for the correction of moderate to severe NLF in Chinese adults. Eligible subjects will be enrolled and randomized either to the treatment group or control group in a 1:1 ratio on Day 0. Each subject assigned to the treatment group will receive TEOSYAL® PureSense ULTRA DEEP in both NLFs, whereas subjects assigned to the control group will receive Restylane® Lidocaine. The treating investigator will administer the corresponding product in both NLFs of the subject on Day 0. All subjects will return to the site at 4, 12, 24, 36, and 52 weeks after the last treatment for effectiveness and safety assessment. All subjects will receive a safety phone call 7 days after the initial treatment at baseline, and after the touch-up treatment, if applicable.
Delayed graft function (DGF), delineated by the necessity for dialytic intervention within the initial week post-transplantation, afflicts approximately 20%-50% of recipients. The primary objective of this study is to investigate the potential efficacy of norepinephrine infusion in conjunction with goal-directed fluid therapy (GDFT) in mitigating the occurrence of DGF among individuals undergoing kidney transplantations. The findings of this investigation have the potential to advance the field of perioperative care in kidney transplantations by providing insights into optimized management strategies.
Hepatic encephalopathy is a brain dysfunction caused by liver insufficiency and/or porto-systemic shunt. It manifests as a wide spectrum of neurological or psychiatric abnormalities ranging from subclinical alterations to coma. According to the symptoms, it is classified as covert HE (CHE) and overt HE (OHE). CHE can progress to OHE and is associated with reduced driving ability, increased risk of accidents and hospitalization and weakened health-related quality of life, resulting in poor prognosis and socio-economic status. However, due to the absence of readily identifiable clinical symptoms and signs, CHE is often neglected in clinical practice. Presently, the diagnosis of CHE depends on psychometric and neurophysiological tests, including the psychometric hepatic encephalopathy score (PHES), critical flicker frequency (CFF) test, continuous reaction time (CRT) test, inhibitory control test, the SCAN test, and electroencephalography. Among them, PHES is most widely used and recommended by several guidelines. However, it is difficult to screen CHE among all cirrhotic patients in the clinic using PHES because of the time required and a dependence on trained experts. Moving beans from one container to another with tweezers involves dexterity, agility and coordination.The hypothesis was that the utility of the Clamping Bean Test (CBT) will enable early screening patients with CHE.
This study is a Phase II, single-arm, open-label, non-randomized, dose-escalation clinical trial to evaluate the efficacy and safety of ssCART-19 Cell Injection in the treatment of patients with CD19 positive Relapsed or Refractory acute lymphoblastic leukemia, including central nervous system infiltration.
