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.
In modern cataract surgery, residual astigmatism continues to be one of the major factors influencing patients' visual quality and satisfaction. The goal of this study is to compare the clinical outcomes of femtosecond laser arcuate keratotomy in one eye and Toric intraocular lens implantation in the contralateral eye for astigmatism correction in patients undergoing femtosecond laser-assisted cataract surgery. The study is a prospective randomized comparative study. Patients with binocular regular corneal astigmatism ranging from 0.75 to 3.00 D will be recruited. The patient will randomly receive femtosecond laser arcuate keratotomy in one eye and receive Toric intraocular lens implantation in the contralateral eye. Long term evaluation will be performed to compare the visual acuity, subjective manifest refraction, and corneal topography between groups.
Due to dMMR colon cancer patients respond poorly to conventional chemotherapy, but immunotherapy can significantly improve the pCR in this group of patients, this study intends to explore whether neoadjuvant immunotherapy can improve the R0 resection rate with preservation of adjacent organs in T4 colon cancer patients with dMMR.
This study is a single-arm, open-label, exploratory clinical trial designed to assess the effectiveness and safety of the combination therapy of Cadonilimab and Lenvatinib for conversion treatment in unresectable hepatocellular carcinoma. Eligible patients, meeting the inclusion criteria and providing informed consent, will undergo 3-4 cycles of Cadonilimab and Lenvatinib conversion therapy. A single imaging assessment will be conducted, and successfully converted patients will proceed to surgical treatment, with pathological evaluation of intraoperative specimens. Post-surgery, patients will choose an appropriate adjuvant treatment based on prior treatment benefits, disease baseline, and personal preferences. Patients who do not successfully convert and experience disease progression will exit the study for alternative treatment. Those who do not successfully convert but do not exhibit disease progression will continue conversion treatment with Cadonilimab and Lenvatinib±TACE/HAIC, with tumor imaging assessments every 3 cycles. Successfully converted patients will undergo surgery, followed by the selection of an appropriate adjuvant treatment based on prior treatment benefits, disease baseline, and personal preferences. Patients who do not successfully convert and experience disease progression will exit the study for alternative treatment. Those who do not successfully convert but do not exhibit disease progression will continue conversion treatment with Cadonilimab and Lenvatinib±TACE/HAIC until disease progression or intolerable toxicity occurs, with a maximum treatment duration of 2 years. Efficacy assessment will use mRECIST and RECIST v1.1 criteria, and safety evaluation will follow CTCAE 5.0 standards. Adverse events will be recorded throughout the study, with a period extending to 60 days after treatment completion for serious adverse events or those related to Enfortumab Vedotin, and in some cases extended to 90 days post-treatment.
The main question it aims to answer are: 1. whether the new target delineation scheme can improve Progression-free Survival 2. whether it can reduce the incidence of radiation complications in high-grade glioma patients. Participants in trial group will be performed radiotherapy of new target delineation method after the completion of the operation within 4-6 weeks., while participants in the control group be performed radiotherapy of EORTC(European organisation for research and treatment of cancer) target delineation method.Temozolomide 75 mg / ( m² · d ) will be given to both groups of patients during radiotherapy. After radiotherapy, its dose changes to 150 ~ 200 mg / ( m² · d ) for 5 days and stopped for 23 days as a cycle. There are 6 cycles in total.
The goal of this clinical trail is to compare the effects of preoperative exercise training of different intensities on short-term cardiorespiratory function and postoperative outcomes in patients scheduled for lung resections.
The goal of this clinical trial is aims to: 1. Translate and culturally adapt the Cognitive Leisure Activity Scale (CLAS) into Chinese and Conduct reliability and validity tests for the Chinese version of CLAS. 2. Investigate the correlation between cognitive leisure activity levels and cognitive function in the preclinical stage of Alzheimer's Disease (AD). 3. Clarify the regulatory mechanisms of cognitive leisure activity levels on the neural circuits of patients in the preclinical stage of AD.
Acute respiratory distress syndrome (ARDS) is a heterogeneous syndrome with similar clinicopathological feathers caused by different etiologies. Respiratory supportive strategies is the main ARDS management, and the guidelines recommend low tidal volume to improve clinical outcomes. To be note, overdistension can still occur even if using a tidal volume as low as 6 ml/kg, given the heterogeneous nature of the syndrome. Therefore, adjusting tidal volume level to less than 6ml/kg may reduce ventilator-induced lung injury (VILI) and thus improve outcomes, especially in patients with severe lung injury. Prone position is also an important management in severe ARDS. Prone position can improve ventilation-perfusion (V/Q) matching and reduce the risk of VILI by recruiting dorsal collapsed alveoli. Meanwhile, prone position has also been shown to improve hemodynamics. Recent studies have showed that prone position did not reduce duration of venovenous extracorporeal membrane oxygenation (VV-ECMO) and 90-day mortality in patients with ARDS who receive VV-ECMO with ultra-low tidal volume ventilation. Therefore, the effect of PP on ventilation and lung blood flow in ARDS patients treated with VV-ECMO wiht ultra-low tidal volume ventilation remains unclear.
This is a study to evaluate the safety, tolerability, pharmacokinetics, and food effects of SHEN211 tablet in healthy subjects after fasting single or multiple oral administration
The goal of this observational study is to evaluate and predict the risk associated with cerebral cavernous malformations (CCMs) using advanced artificial intelligence and radiomics analysis technology. The study focuses on individuals who have been diagnosed with cerebral cavernous malformations (CCMs). Main Questions to Answer: How can AI-based radiomics features predict the risk of complications (such as bleeding or epilepsy) in individuals with CCMs? What are the most reliable imaging and clinical markers for assessing the prognosis of CCMs? Participants will be required to undergo regular medical imaging to gather traditional and radiomics imaging features. Participants will provide clinical data, including past medical history and results of any laboratory tests. Participants will be part of a three-year follow-up observation to monitor the progression or stability of CCMs. Contribution of biological samples for advanced testing might also be requested. This study aims to create an AI-based decision-making tool that will guide clinicians in the management of CCM, with the potential to significantly improve patient outcomes through personalized medical approaches.
This study in China is open to adults who are at least 18 years old who are living with overweight or obesity. People with a body mass index (BMI) of 28 kg/m^2 or higher or 24 kg/m^2 or higher with at least 1 weight related problem can join the study. The main purpose of this study is to find out whether a medicine called survodutide helps people with overweight or obesity. 2 different doses of survodutide are tested in this study. Participants are put into 3 groups by chance. Each participant has an equal chance of being in each group. 2 groups get different doses of survodutide. 1 group gets placebo. Participants get survodutide or placebo as injections under the skin once a week for about 19 months. Placebo injections look like survodutide injections but do not contain any medicine. Participants are in the study for about 21 months. During this time, there are 20 visits. 14 visits are in person at the study site. Where possible, 6 visits can be done by video call, or by phone in rare cases. During this time, doctors regularly measure participant's body weight. Results are compared between the survodutide groups and placebo group to see whether the treatment works. The doctors also regularly check participants' health and take note of any unwanted effects.
