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.
Despite declining incidence rates, gastric cancer (GC) ranks the fourth leading cause of cancer-related mortality and the fifth most common cancer worldwide, with the highest incidence reported in Eastern Asia. The 5-year overall survival rate of early GC exceeds 90%, which was well above advanced GC. Most intestinal-type GCs follow the Correa cascade-inflammation,atrophy, intestinal metaplasia (IM), dysplasia and subsequent carcinoma. The presence of gastric mucosal atrophy and intestinal metaplasia are important risk factors for GC. The purpose of this study was to investigate the incidence of GC attributed to atrophic gastritis in a region with high incidence of GC.
The goal of this prospective cohort study is to investigate the associations between Epstein-Barr Virus (EBV) antibody levels and the risk of overall and site-specific cancer types in Southern China. The main questions it aims to answer are: Question 1: In addition to the established EBV-associated cancer types, such as lymphomas, nasopharyngeal carcinoma, and stomach cancer, whether EBV is associated with other cancer types? Question 2: What's the cancer burden attributed to EBV in Southern China?
The purpose of this study was to analyze the relationship between the microbial community, host immunity and the presence or absence of concurrent rapidly progressive interstitial lung disease patients with anti-MDA5 antibody positive dermatomyositis.
This study was designed to compare the efficacy and safety of I-DXd with treatment of physician's choice in participants with relapsed small cell lung cancer (SCLC).
The loss of response rate of ustekinumab(UST) is high, and the specific mechanism has not yet been elucidated. Molecular markers that can accurately predict the efficacy of UST are urgently needed to provide theoretical basis for guiding individualized treatment. Therefore, this study intends to explore the impact of intestinal epithelial fucosylation levels on the efficacy of UST in patients with Crohn's disease(CD), aiming to provide predictable molecular markers for UST to accurately treat CD.
Multiple myeloma (MM) is still an incurable hematological tumor, and renal involvement is the main factor of poor prognosis. The recovery of renal function can partially reverse its poor outcome. Although the 5-year survival rate of MM patients has significantly improved after entering the era of new drugs, patients with severe renal insufficiency still have a high early mortality.The purpose of this study is to investigate whether early intensive chemotherapy can reverse the proportion of renal insufficiency, is to investigate the treatment effect of RIMM patients with different renal pathological types, and is also to investigate whether autoHSCT can further partially save renal function in RIMM patients.
This is an open-label positron emission tomography/computed tomography (PET/CT) study to investigate the clinical predictive value of 68Ga-DOTA-BPP in subjects with triple-negative breast cancer. The visual and semiquantitative methods will be used to assess the PET/CT images
The study aims to explore the efficacy and safety of an intravaginal acetic acid thermoreversible gel in Chinese women of reproductive age, comparing it with nonoxinol gel by assessing the six-month Pearl Index and the incidence of any side effects.
Stroke is a common and frequently-occurring disease in the world. Patients with stroke often have sequelae and functional disorders of varying degrees, among which the disturbance of consciousness has the greatest impact on prognosis and quality of life.At present, drug therapy, neurosurgical interventional therapy and modern physical therapy are mainly used for post-stroke consciousness disorders. The above therapies to improve the state of consciousness of patients are not supported by sufficient evidence-based evidence, and the other is that they have shortcomings, such as invasive, expensive, and strict indications. Acupuncture has been used in the treatment of sequelae of stroke for thousands of years in China. Tongyuan acupuncture is a set of traditional Chinese medicine therapy pioneered by Professor Lai Xinsheng, a famous doctor of Chinese medicine. A large number of previous studies have proved that Tongyuan acupuncture has a unique effect on the cardiovascular system, gynecology, ent, neurology and other functional disorders. In this study, Tongyuan acupuncture was used in patients with post-stroke consciousness disorder to observe its efficacy and explore the mechanism of action. The purpose of this study is to investigate whether Tongyuan acupuncture can improve the consciousness disorder after stroke, and to provide a new safe, effective, feasible and easy to popularize treatment method.
The goal of this clinical trial is to compare the differences in feeding amount and nutritional status between ischemic stroke patients using Intermittent Oro-esophageal Tube and Nasogastric Tube. Patients will be randomly divided into an observation group and a control group, all receiving routine rehabilitation treatment. On this basis, the observation group will use Intermittent Oro esophageal Tube for enteral nutrition support, while the control group will use Nasogastric Tube. Researchers will compare changes in daily intake and nutritional status of two groups of patients before and after the study to see if Intermittent Oro-esophageal Tube can improve the feeding amount and nutritional status between ischemic stroke patients compared to Nasogastric Tube
