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.
In this study, gastrointestinal anastomoses are examined with imaging Photoplethysmography and after this the investigators use the Standard Routine ICG-Imaging. At the end, both methods will be compared.
It is a phase II open label, multicenter study to assess the safety, tolerability, pharmacokinetics, and efficacy of HB0025 in patients with advanced clear cell renal cell carcinoma (ccRCC).
The goal of this observational study is to learn about in Patients treated with postoperative chemotherapy for ovarian tumors. The main questions it aims to answer are: • [What symptom clusters are present in patients treated with postoperative chemotherapy for ovarian tumors] • [Are there differences in symptom clusters for patients with different TCM body types] Participants will [complete questionnaires prior to the start of chemotherapy and after the 1st, 3rd, and 6th chemotherapy treatments].
This is a single-center, prospective, observational study intended to include patients receiving TIPS for portal hypertension. Baseline data of enrolled patients were recorded, and samples of ascites, feces and urine were collected before surgery. Venous blood (superior mesenteric vein, hepatic vein, peripheral vein) from different parts of the entero-hepatic axis was retained during operation, and patients were followed up regularly for 2 years. The incidence of infection, hepatic encephalopathy, upper gastrointestinal hemorrhage and ascites in patients with portal hypertension who received TIPS intervention were observed within 3 months after operation. And the stent patency was observed within 2 years after surgery. To investigate the characteristics of microbial, protein and metabolic components on enterohepatic axis and their relationship with prognosis of patients with cirrhosis by detecting microbiome, proteome and metabolome.
The goal of this observational study is to learn about the value of multimodal ultrasound in early detection of left ventricular systolic dysfunction in patients with chronic kidney disease(CKD). The main questions it aims to answer are: 1. If first-phase ejection fraction（EF1）could early detect the left ventricular systolic dysfunction in patients with CKD. 2. Whether EF1 can detect left ventricular systolic dysfunction in patients with CKD more sensitively than speckle-tracking echocardiography and myocardial work. Participants will need to cooperate to do an echocardiography. Researchers will compare healthy volunteers and patients with CKD to see if EF1 could early detect the left ventricular systolic dysfunction.
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 purpose of this study is to evaluate the efficacy and safety of Disitamab Vedotin Combined with Cadonilimab in subjects with HER2-expressing locally advanced or metastatic gastric cancer and gastroesophageal junction adenocarcinoma after progression on first-line therapy.
The goal of this observational study is to identify the characteristics of brain functional connectivity in refractory constipation and fluoxetine-sensitive patients. The main questions it aims to answer are: - Investigating the alterations in brain functional connectivity in patients with refractory constipation and fluoxetine-sensitive patients - Assessing the predictive value of brain functional connectivity regarding the efficacy of fluoxetine and standard protocol treatments for constipation. Participants will receive: - Standard physiological and psychological assessments of constipation - BOLD-fMRI tests - Standard protocol and fluoxetine treatment If there is a comparison group: Researchers will compare: Refractory group/Fluoxetine sensitive group to see the specific brain alterations.
The goal of this clinical trial is to estimate the rate (probability) of complete remission or complete remission with incomplete count recovery (CR/CRi) with negative MRD after induction I and II, event-free survival (EFS), and cumulative incidence (probability) of relapse (CIR), in patients receiving molecular/precision medicine and MRD-driven remission inductions, and to assess secondarily if there is an improvement over the AML2018 protocol.
Fruquintinib, as a standard treatment for refractory metastatic colorectal cancer (mCRC), has attracted increasing research efforts to explore its innovative strategies in combination with immunotherapy and chemotherapy because of its multi-target mechanism which enhances the sensitivity of the immune system and chemotherapy, aiming to further improve the survival benefits for mCRC patients. Trifluridine/tipiracil (TAS-102) is also a standard treatment for mCRC. This study aims to investigate the safety and effectiveness of the combined use of these two drugs in mCRC.
