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.
So far, the number of COVID-19 infections worldwide has exceeded 700 million. Long-term damage to the lungs is a major sequela of COVID infection. Pulmonary function testing is an important means for the evaluation of lung damage. MRI examinations with free breathing and no contrast agent can prevent patients from suffering from ionizing radiation damage caused by multiple CT examinations.
Hepatopulmonary syndrome (HPS) has unknown pathogenesis, limited treatment and poor prognosis. The onset of HPS is insidious and easy to be ignored. Many liver diseases such as "cirrhosis and related complications" are the core characteristics of Beijing You 'an Hospital, but the clinical characteristics of HPS patients in the center are still unclear. The investigators plan to make the diagnosis of HPS among chronic liver disease patients in the hospital according to the diagnostic criteria of HPS proposed in the Practice Guidelines of the International Society of Liver Transplantation in 2016, collect clinical data of HPS participants, evaluate the severity, analyze and summarize clinical characteristics, and conduct management and follow-up. At the same time, The investigators collect blood samples for proteomics tests. In order to improve the diagnosis and treatment level of HPS.
This study is aimed to establish an organoid-on-chips technological system based on biopsy samples and evaluate its efficacy in predicting the response to mFOLFOX6 infusion in patients with hepatocellular carcinoma (HCC).
To investigate the intervention effect of high definition transcranial alternating current stimulation (HD-tACS) on suicidal ideation in patients with depressive disorder and its underlying neural mechanism by magnetic resonance imaging (MRI) and electroencephalography (EEG).
Human papillomavirus (HPV) is currently one of the most common sexually transmitted infections, according to its carcinogenicity is divided into high-risk genotypes and low-risk genotypes, research has confirmed that carcinogenic HPV type continuous infection leads to a higher incidence of condyloma acuminatum and cervical cancer, while increasing the oropharyngeal cancer, vaginal cancer and other related cancer risk. HPV vaccines have been widely introduced worldwide to prevent cancers of the lower genital tract such as cervical, anal and vulvar cancers. For different types of HPV vaccine, divided into domestic bivalent, imported bivalent (GlaxoSmithKline), quadrivalent (Merck) and nine-valent (Merck) HPV vaccine, four vaccines all prevent HPV 16/18 high-risk type infection disease, and the four and nine-valent HPV vaccine prevention genotypes are different, and different price number of protection rates, vaccination objects and immunization procedures are slightly different. At the same time, studies have shown that women after HPV vaccine, arm redness, swelling, heat and pain have a high incidence of adverse reactions, often accompanied by menstrual disorders, sleep problems, emotional irritability, fever, dizziness, headache and other adverse reactions risk, so we plan to design a multicenter cohort study to evaluate the effectiveness of HPV vaccine with different prices. At the same time, the adverse reaction symptoms of HPV vaccine in the female population of appropriate age were monitored.

Human papillomavirus vaccines have been widely used worldwide to prevent cancers of the lower reproductive tract, such as cervical, anal and vulvar cancers. According to the type, it is divided into domestic two-valent (Vantage), imported two-valent (GlaxoSmithKline), four-valent (Merck) and nine-valent (Merck)HPV vaccines. All four vaccines prevent high-risk HPV 16/18 infection, and there are differences between the quadrivalent and nine-valent HPV vaccine prevention genotypes. The protection rate, immunizing target and immunizing procedure of different valence number are slightly different. Studies have shown that after women receive HPV vaccine, the incidence of arm redness, swelling, fever, pain and other adverse reactions is high, often accompanied by menstrual disorders, sleep problems, emotional irritability, fever, dizziness, headache and other adverse reactions. However, the causal relationship between HPV vaccination and symptoms after vaccination at different prices is controversial, and there is little research in this area. Therefore, we intend to design a multicenter, bidirectional cohort study to investigate the relationship between HPV vaccination with different valence numbers and adverse reactions after vaccination in Chinese women, and to further explore the unknown potential factors affecting the protective effect of HPV vaccine.
A randomized, open-label, multicenter, phase 2 trial to compare the efficacy and safety of baricitinib plus high-dose dexamethasone compared to high-dose dexamethasone monotherapy for the first-line treatment of adults with primary immune thrombocytopenia (ITP).
Post-operative new-onset atrial fibrillation (POAF) is one of the most common arrhythmias in adults after direct intracardiac surgery with extracorporeal circulation. The incidence of POAF in coronary artery bypass grafting (CABG) is approximately 30%. POAF can lead to an increased risk of complications such as stroke, heart failure, and acute kidney injury, which not only prolongs the patient's hospital stay, but also increases hospital costs and mortality. operation, extracorporeal circulation, and the patient's underlying conditions (such as age, gender, hypertension, and diabetes), which cause sympathetic activation, inflammatory response, and myocardial ischemia in the organism. The stellate ganglion block (SGB) regulates the sympathetic tone of the innervated nerves and thus the autonomic function of the body. SGB can effectively regulate the sympathetic-parasympathetic imbalance. Also, SGB may exert some anti-inflammatory effects. In this study, ultrasound-guided SGB was used in CABG patients to investigate its effect on the occurrence of POAF.
It is a single-center, open-labeled, single-arm, non-randomized, investigator-initiated trial aiming to evaluate the efficacy and safety of anti-CD19 CAR-T manufactured by OlyCAR platform (OlyCAR-019) for CD19+ refractory/relapsed B-Cell malignancies.
This study is to explore the relationship between intravenous infusion of dextrose during emergence from anesthesia and the incidence of PONV in patients undergoing gynecology laparoscopy (GL).
