There are about 36570 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.

Dementia is a chronic, progressive neurodegenerative disease characterized by acquired cognitive impairment as its core manifestation. The most common type of dementia is Alzheimer's Disease (AD), also known as "Senile Dementia," accounting for 60-80% of all dementia cases. Currently, there are approximately 10 million AD patients in China, with the number showing an increasing trend year by year, imposing a heavy economic and caregiving burden on families and society. Studies have shown that AD has a clinically silent period of 15 to 20 years (SCD\MCI), where the risk of developing dementia is ten times higher than that of healthy elderly individuals. Nearly 50% of MCI patients progress to dementia within 5 years, and about 14.1% of SCD patients develop dementia within the same timeframe. Early detection, diagnosis, and intervention are currently the most effective strategies for preventing and treating AD. Therefore, this study aims to verify the intervention effect of integrated cognitive intervention in high-risk populations for senile dementia (SCD, MCI) based on the cognitive rehabilitation model through randomized controlled trials, and to analyze attrition rates, participation rates, etc., which have good research and application value.
Alzheimer's Disease, AD is a type of neurofibrillary tangles formed by the deposition of beta amyloid proteins within the nervous system cells and excessive phosphorylation of extracellular Tau proteins, NFTs are the main pathological features of central nervous system degeneration, also known as senile dementia. In addition, synaptic plasticity damage and neuroinflammation also play important roles in the progression of AD. Neurosynapses are the sites where neurons interact with each other in terms of function, and are also crucial for neuronal information transmission and communication. Synapses are the fundamental units in the brain, and synaptic activity can stimulate the maturation of mushroom like dendritic spines and form new synapses, enabling synaptic strength to adapt to changes in the internal and external environment, thereby playing an important role in learning and memory. Previous studies have shown that synaptic activity interruption and synaptic loss can already be detected in the AD brain, especially in the early stages. Multiple studies have shown a higher correlation between synaptic disorders characterized by synaptic loss and decreased synaptic activity and cognitive impairment in Alzheimer's disease compared to age-related plaques and neurofibrillary tangles. Therefore, understanding the potential mechanisms of synaptic disorders will contribute to the development of early treatment strategies for AD. MicroRNAs (miRNAs) are a type of small non coding RNA with a length of approximately 22 nucleotides. Their main function is to silence target genes at the post transcriptional level and inhibit the translation process of their proteins. MiRNAs are involved in many physiological processes and pathological pathways, including development, tumorigenesis, and heart disease. Recently, people have also studied the abnormal regulatory role of miRNAs in AD synaptic disorders. Some miRNAs enriched in the brain, such as miR-124, MiR-132 is abnormally expressed in the AD brain, mediating synaptic plasticity damage. However, most of the miRNAs mentioned above are not directly related to synaptic activity, and their regulation of AD synaptic damage is likely to be a broad-spectrum effect. At present, there are 12 miRNAs closely related to synaptic plasticity that have been identified. By detecting changes in miRNAs closely related to synaptic plasticity in peripheral blood of AD patients and healthy volunteers, and exploring their relationship with the severity of AD lesions, it may provide new directions for early diagnosis of AD. The purpose of this study is to: (1) detect the expression levels of miRNAs closely related to synaptic plasticity in the peripheral blood of healthy volunteers and AD patients, and identify the miRNAs with the greatest differences; (2) Analyze the relationship between the expression levels of the aforementioned miRNAs in the peripheral blood of AD patients and the severity of the disease; (3) Analyze the relationship between the expression levels of the aforementioned miRNAs in the peripheral blood of AD patients and the commonly used neuropsychiatric scale scores. We plan to clarify the changes in peripheral blood miRNAs and their relationship with the severity of AD through case-control studies, in order to provide new directions for early diagnosis of AD.
Bladder cancer is the ninth most common malignant tumor worldwide, characterized by high malignancy and poor prognosis. We intend to develop a CT-based tumor budding predictive model for bladder cancer using deep learning algorithms. This model will facilitate preoperative assessment of patient conditions, enabling the formulation of more precise and personalized treatment plans.

The objective of this clinical trial is to evaluate the efficacy and safety of combining fruquintinib with hepatic artery infusion (HAI)-FOLFOX in the treatment of refractory colorectal cancer with liver metastasis.
this study will use traditional Chinese medicine bath with no obvious side effects combined with case tracking management mode to form nursing measures to prevent hand foot syndrome. A randomized controlled trial design will be used to collect cases of hand foot syndrome (HFS) that did not appear after chemotherapy in the ward of the Department of chemotherapy, Peking University Third Hospital, and carry out nursing intervention.
The core purpose of this study is to investigate whether the extracellular volume (ECV) fraction measured in delay phase by dual energy computed tomography (DECT) can distinguish precancerous lesions from early-stage lung adenocarcinomas, which could assist clinical decision making for surgery operation indication and strategy.
Previous studies have reported the efficacy of Bacillus Calmette-Guérin (BCG) combined with other drugs for the treatment of bladder cancer. However, research on the combination of tislelizumab and BCG for bladder cancer treatment has largely been retrospective. Currently, ongoing clinical trials have not discussed the effectiveness of PD-1/PD-L1 inhibitors combined with BCG instillation in reducing postoperative recurrence in intermediate-risk NMIBC. Therefore, this study aims to explore the clinical efficacy and safety of tislelizumab combined with BCG in the treatment of intermediate and high-risk NMIBC. For this purpose, investigators have established strict screening criteria to include eligible patients in the study and have recruited suitable patients from multiple medical centers.Investigators have also developed a meticulous implementation process and follow-up considerations, hoping to better verify the clinical efficacy and safety of the combined use of these two drugs.
