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.
The goal of this observational study is to learn about the difference of refractive outcomes between Artificial Intelligence and experienced surgeon predicting Nomogram assist SMILE surgical design and the influenced factors of refractive outcomes in patients who underwent Small Incision Lenticule Extraction(SMILE) at the Refractive Surgery Center of Tianjin Eye Hospital. The main questions it aims to answer are: - Compare the difference of refractive outcomes between Artificial Intelligence and experienced surgeon predicting Nomogram assist SMILE surgical design - Analysis the influenced factors of refractive outcomes
The goal of this clinical trial is to compare the PCR rate between Total Neoadjuvant Treatment ±Immunotherapy in high risk locally advanced rectal cancer. The main questions it aims to answer are: - The PCR rate between the two groups - The 3years DFS between the two groups - Chemoradiotherapy and immunotherapy toxicity - Postoperative complications Participants will receive total neoadjuvant treatment ±immunotherapy followed by surgery. Researchers will compare neoadjuvant treatment ±immunotherapy to see the PCR rate.
Describe the efficacy and safety of Orelabrutinib in the treatment of HP-positive gastric MALT lymphoma
This study aims to investigate the prognostic value of circulating plasma cells (CPCs) in patients with multiple myeloma and explore whether CPCs detection might be used in place of bone marrow aspiration for disease monitoring.
To explore the relationship between perioperative blood pressure and catecholamine concentrations in adrenal venous blood and peripheral venous blood in hypertensive patients with primary aldosteronism (PA) who underwent percutaneous selective adrenal artery embolization (SAAE). In order to elucidate the related phenomena and possible mechanisms of blood pressure fluctuations caused by SAAE treatment in hypertensive patients with PA.
The study is a Phase II, multicenter, randomized, double-blind study to evaluatethe efficacy and safety of LP-003 administered subcutaneously as an add-on therapy for the treatment of adult patients aged 18-75 who have been diagnosed with refractory CSU and who remain symptomatic despitestandard-dose H1 antihistamine treatment.
This is one center, single-arm, open-label investigator initiated trial to assess the safety and efficacy of enhanced autologous PSMA chimeric antigen receptor T cells in the treatment for patients with refractory castration resistant prostate cancer, and the sample size is set to 7-18 subjects.
Multidrug resistant bacteria (MDR) pose a threat to the safety of patients worldwide. Drug resistant bacteria are commonly present in hospital environments and can cause infections, often leading to outbreaks within hospitals. Cross transmission through medical staff has been proven to be a significant cause of MDR bacterial transmission in hospitals. Although some studies have shown that the detection of gut drug-resistant bacteria in healthcare workers is similar to that in healthy individuals, these studies are limited to small sample sizes and detection methods. Here, the investigator characterize the differences between ARG colonization among healthcare workers and healthy populations through deep metagenomics.
The main objective is to analyze the abnormality of physical condition, mental health and blood examination of the patients with benign paroxysmal positional vertigo (BPPV). Besides, the investigators aim to establish a database of BPPV based on multimodal magnetic resonance imaging data in the brain to identify high-risk patients with residual dizziness (RD) and systematically establish the comprehensive assessment system for the precise diagnosis, treatment and recovery of RD, optimize the tactics of BPPV management in China.
This interventional study targets female students in junior middle school. It goal is to evaluate the effectiveness of a vaccine chatbot on HPV vaccine awareness and vaccination. The main questions it aims to answer are: 1. How will the novel digital tool, a vaccine chatbot, impact eligible parents' awareness and knowledge of HPV vaccines, their willingness to vaccinate their daughters, and vaccination status of female students. 2. How is the vaccine chatbots accepted by all stakeholders, and what are the facilitators of and barriers to implementing vaccine chatbot promotion campaign. The intervention group will go through the intervention measure while the control group will not: 1. The intervention group will be invited to use the HPV vaccine chatbot online through WeChat , the mostly widely used social media platform in mainland China, or any web browsers. They can ask any questions related to the HPV vaccine and get validated answers from the chatbot immediately. The intervention lasts two weeks, with invitations sent every four days to reinforce the intervention. 2. The control group will not use the chatbot during the intervention duration. Researchers will compare participants' HPV vaccine awareness, and vaccination intention and status after intervention between intervention group and control group to evaluate if the vaccine chatbot improves HPV vaccine awareness and vaccination.
