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 objective of this research is to investigate the clinical outcomes of modified surgical techniques such as omitting the cervical linea alba suture in transthoracic endoscopic thyroidectomy. Furthermore, the study requires the collection of normal thyroid tissues, benign and malignant thyroid tumors, and lymph nodes to further clarify the mechanisms associated with the initiation, progression, metastasis, and recurrence of thyroid cancer.

Ultrasonic light scattering imaging is a new functional imaging technology that combines traditional B-mode ultrasound imaging and light scattering tomography (DOT). It can improve the accuracy of early diagnosis of breast cancer based on the characteristics of abnormal blood supply and oxygen consumption of lesions. This study aims to evaluate the value of ultrasonic light scattering imaging in the differential diagnosis of benign and malignant breast nodules, and to evaluate the consistency between ultrasonic light scattering imaging and examiners in the differential diagnosis of benign and malignant breast nodules.
The purpose of this study is to investigate the effects of optimal load strength training on the lower limb neuromuscular adaptation of athletes. An anatomical analysis of the vertical jump reveals three phases: the propulsion phase, the flight phase, and the landing phase. This study is an 8-week randomized controlled trial. After selecting the participants, basic information such as height, weight, age, and years of training experience is collected. Subsequently, a maximal output power test for lower limb squatting is conducted. Participants are then randomly assigned to the speed group, power group, and strength group. The optimal power load for the power group is determined based on the participant maximal output power. Training plans are developed for the traditional group, power group, and strength group. Each training session is organized and supervised by a designated person. Surface electromyography, three-dimensional motion capture systems, and force platforms are used to collect electromyographic and kinetic data of participants during pre-test and post-test vertical jump actions. Electromyography evoked potential instruments and myotonometer are used to collect nerve signals of the tibial nerve (posterior calf) and muscle fiber dimension data of the rectus femoris before and after the experiment. Additionally, static full-range-of-motion vertical jump kinematics and kinetics data are collected before and after the experiment. To ensure the quality and validity of the intervention, the following controls are implemented during the experiment: first, communication with the participants to inform them of the purpose of the study and ensure adherence to the correct movement standards during testing; second, having a designated person responsible for resistance training during the experiment; third, using the same equipment and team for testing to maximize the controllability of the experiment process; fourth, providing verbal encouragement to participants during testing to maximize effort and minimize experimental errors. The aim is to determine the effects of optimal load strength training on improving the lower limb output power during the propulsion phase of the take-off stage in long jump athletes and the underlying neuromuscular adaptation mechanisms.
Patients with mechanical ventilation in the intensive care unit (ICU) often develop anxiety and agitation, sleep distuebances, and delirium. Delirium occurrence is associated with worse early and long-term outcomes. Dexmedetomidine and ketamine are recommended for sedation and analgesia in ICU patients, but each may induce side effects. The sedative effects of dexmedetomidine can help mitigate the psychiatric side effects of esketamine. Recent studies showed that dexmedetomidine-esketamine combination improved analgesia and sleep quality without increasing psychiatric side effects. This trial is designed to test the hypothesis that dexmedetomidine-esketamine combination for sedation and analgesia in ICU patients with mechanical ventilation may reduce delirium and improve respiratory recovery.
This is a phase Ib/II, open, dose-escalation and expansion study of an anti-PD1/TIM3 bispecific antibody,LB1410 in combination with an anti-Claudin18.2/IL-10 fusion protein, LB4330 in patients with advanced or metastatic solid tumors.
The objective of this trial is to compare the efficacy of a comprehensive treatment strategy involving PD-1 monoclonal antibody combined with XELOX chemotherapy followed by radical resection surgery, versus simple systemic treatment in patients with limited distant metastasis of gastric adenocarcinoma/gastroesophageal junction adenocarcinoma. After enrollment and successful screening, eligible participants will be randomized in a 1:1 ratio into a surgical arm and a non-surgical arm, and will undergo the following treatment: Surgical Arm: 1. Phase 1 Systemic Therapy: Administration of PD-1 monoclonal antibody in combination with XELOX chemotherapy for cycles 1-4. 2. Surgery: Performing a D2 standard gastrectomy for gastric cancer and radical resection of resectable metastatic lesions. 3. Phase 2 Systemic Therapy: Continuation of PD-1 monoclonal antibody combined with XELOX chemotherapy for cycles 5-8, followed by maintenance therapy with PD-1 monoclonal antibody and capecitabine monotherapy from the 9th cycle until two years post-enrollment. 4. During phase 2 systemic therapy, concurrent local treatments for unresected metastatic lesions are permitted, including radiotherapy, interventional embolization, radiofrequency ablation, and hyperthermic intraperitoneal chemotherapy (HIPEC). Non-Surgical Arm: 1. Phase 1 Systemic Therapy: Administration of PD-1 monoclonal antibody in combination with XELOX chemotherapy for cycles 1-4. 2. Phase 2 Systemic Therapy: Continuation of PD-1 monoclonal antibody combined with XELOX chemotherapy for cycles 5-8, followed by maintenance therapy with PD-1 monoclonal antibody and capecitabine monotherapy from the 9th cycle until two years post-enrollment.
This study is a multicenter, single-arm, prospective phase II clinical trial that evaluates the efficacy and safety of an intensive conditioning regimen with thiotepa combined with busulfan, fludarabine, and cytarabine for allogeneic hematopoietic stem cell transplantation in the treatment of myeloid malignancies with extramedullary involvement. The conditioning regimen includes thiotepa at a dose of 5mg/kg/d at d -7 (1 day), fludarabine at 30mg/m2/d from d -6 to d -2 (5 days), cytarabine at 1g/m2/d from d -6 to d -2 (5 days), and busulfan at 3.2mg/kg/d from d -4 to d -3 (2 days). Conditioning begins on day -7, and donor hematopoietic stem cell infusion is performed on day 0. All patients will undergo bone marrow examination on day 14 and day 28 post-transplant, followed by bone marrow examinations every 30 days within the first year after transplantation, and every 60 days within the second year after transplantation. If disease relapse is suspected during the follow-up period, bone marrow or extramedullary relapse site examinations will be conducted at any time. The primary study endpoints are the 1-year and 2-year progression-free survival (PFS) rates post-transplant. Secondary study endpoints include the incidence of acute graft-versus-host disease (GVHD) within 180 days post-transplant, cumulative relapse rates at 1 year and 2 years post-transplant, 1-year and 2-year overall survival (OS), graft-versus-host disease-free, relapse-free survival (GRFS), non-relapse mortality (NRM), cumulative incidence of chronic GVHD, and the incidence of Cytomegalovirus (CMV)and Epstein-Barr virus(EBV)reactivation within 1 year.
