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.
To evaluate the diagnostic efficiency of the neural network in predicting complications of Small Incision Lenticule Extraction in a multi-center cross-sectional study.
In this study, the investigators will detect hepatocellular carcinoma lesions using fluoescence imaging with ITGA6 targeting probes during tumor resection surgery. The aim is to evaluate wether intraoperative fluorescence imaging targeting ITGA6 can help to improve the detction effect of hepatocellular carcinoma, and finally help the accurate surgical resection. The main purposes of this study include: 1. To raise the detection rate of hepatocellular carcinoma intraoperatively using the novel NIR-II fluorescence molecular imaging and the ITGA6 targeting probe. 2. To validate the safety and effectiveness of the proposed ITGA6 targeting probes for clinical application.
The goal of this clinical trial is to evaluate the safety and efficiency of stent-based tiverting technique (SDT) versus ileostomy in rectal cancer patients. After the removal of the rectal tumor, participants who are at high risk for anastomotic leakage will either undergo SDT or ileostomies. Researchers will compare SDT to see if SDT could help patients save hospital stays, lower medical costs, and enhance their quality of life, and not alternatively avoid defunction stoma.
The aim of this clinical trial is to test whether minimal residual disease (MRD) status detected by circulating tumor DNA (ctDNA) could be used to guide precision therapy of post-surgery in colon cancer. The colon cancers are intended for resectable colon cancer of high-risk stage II and low-risk stage III status. The main questions it aims to answer are: 1. Whether patients with MRD negative status could benefit from deferred adjuvant therapy. 2. Whether patients with MRD positive status need intensive adjuvant therapy. The qualified participants will go through two different randomized groups according to the post-surgery 1-month MRD status. In MRD negative groups, participants will be divided into standard adjuvant therapy groups and deferred adjuvant therapy groups at 1:2 ratios. In MRD positive groups, participants will be divided into standard adjuvant therapy groups and intensive adjuvant therapy groups at 1:2 ratios. All the patients will receive MRD detection every 3 months and radiological evaluation every 6 months up to 3 years, and survival follow-up up to 5 years.
The purpose of the study is to assess the safety, tolerability and pharmacokinetics of XH-S002 in healthy volunteers under SAD (Single ascending dose) and MAD (Multiple ascending dose) studies. In addition, this study evaluates the food effects of XH-S002.
Upper tract urothelial carcinoma (UTUC) is a rare malignant disease which accounts for 5-10% of urothelial carcinoma in the western world and 9%-30% in China. About two thirds of patients have muscle invasive disease at diagnosis. Those patients usually have poor prognosis. The 5 year cancer specific survival is <50% for pT2/T3 and <10% for pT4. Radical nephroureterectomy is the standardized treatment for non-metastatic high risk UTUC. However, about half patients may suffer from impaired renal function after nephroureterectomy. On the other hand, kidney sparing surgery can avoid renal function impairment, but the therapy is only recommended for few patients with low-risk disease. The treatment for urothelial carcinoma has changed rapidly in the past few years. Immune checkpoint inhibitors and novel agents such as ADCs have shown promising therapeutic effect and were approved for patients with metastatic UTUC. Meanwhile, a recent study shows that patients with high-risk disease can also receive kidney sparing surgery without compromising cancer specific survival and overall survival. This prospective, observational study aims to evaluate the prognosis of contemporary kidney sparing surgery in patients with UTUC with or without perioperative therapy in the real world.
The goal of this observational study is to learn about the correlation between COVID-19 and hyperthyroidism in Patients with hyperthyroidism complicated with COVID-19. The main questions it aims to answer are： - The main research object is Graves disease (GD) patients. - Changes of hyperthyroidism in GD patients complicated with COVID-19 - Changes of anxiety and depression in GD patients before and after SARS-CoV-2 infection. - The effect of psychological intervention in GD patients after COVID-19. Participants will have regular follow-upfor one year to hyperthyroidism in our hospital, and the investigators will collect the thyroid function and related examination indexes of patients in the corresponding time period.
Aggressive fibromatosis, also known as desmoid fibromatosis or desmoid tumor, is a fibrous tumor that occurs in the fascia, aponeurosis, or deep soft tissue and is formed by excessive proliferation of fibroblasts and myofibroblasts. At present, the disease is considered to be a borderline tumor. Due to the unclear boundary of the tumor, it often grows into the surrounding adjacent tissues, which is difficult to remove completely and easy to relapse. It has been reported that nuclear β-catenin expression and CTNNB1 gene mutation can be used for the differential diagnosis of aggressive fibromatosis from other spindle cell lesions. At present, there is a lack of multicenter retrospective clinical study of this disease, and there is no literature report on the postoperative quality of life of this kind of patients. This study intends to further explore the clinicopathological features, prognosis and molecular typing of abdominal wall aggressive fibroma by retrospective analysis of the case data of multiple hospitals, as well as sequencing analysis of the retained specimens and paraffin specimens from previous operations, to study the high risk factors for recurrence of the disease, and to further comprehensively analyze the impact of abdominal wall aggressive fibroma surgery on the quality of life of patients through follow-up.
By collecting non-image medical data of women undergoing cervical screening in multiple centers in China, including age, HPV infection status, HPV infection type, TCT results, and colposcopy biopsy pathology results, a multi-source heterogeneous cervical lesion collaborative research big data platform was established. Based on artificial intelligence (AI) machine learning, cervical lesion screening features are refined, a multi-modal cervical cancer intelligent screening prediction and risk triage model is constructed, and its clinical application value is preliminarily explored.
This study aims explored the effectiveness of dual psychological intervention strategies in improving the quality of life of MHD patients based on the theoretical guidance of double ABC-X model. To provide a scientific and effective dual psychological intervention strategy for MHD patients and their caregivers, in order to improve the quality of life of MHD patients, and to provide a reference for nurses in clinical blood purification centers to implement psychological intervention.
