A multicenter, prospective, randomized, double-blind, placebo-controlled clinical trial was designed to evaluate the efficacy and safety of Prunella oral liquid in patients with benign thyroid nodules, which belongs to the post-marketing reevaluation clinical study. In this study, 426 subjects will be enrolled by competitive enrollment at several research centers across China. The main inclusion criteria are: ① Thyroid ultrasound examination found thyroid nodules, can be accompanied by goiter, and the nodules meet the following conditions: 1) There were dominant nodules in single or multiple nodules (the largest diameter of the second largest nodules was not more than 50% of the largest nodules), 2) solid nodules, 3) the longest diameter of nodules was ≥1cm and < 3cm, 4) C-TIRADS 3~4A nodules. ② Patients who met the puncture indication were confirmed by fine needle aspiration biopsy (FNAB) as benign nodules (Bethesda II). ③ Levels of TSH, FT3 and FT4 were normal, and the antibody titers of TgAb and TPOAb were normal. Eligible subjects will be randomly assigned on a 1:1:2:2 scale to: Group A (placebo conventional dose group, 10 mL/times, 2 times/day), group B (placebo 2x dose group, 10ml/times, 2 times/day), group C (conventional dose group of Prunella oral liquid), group D (Prunella oral liquid 2x dose group). All subjects will receive the treatment for 9 months and follow up at 3rd, 6th, 9th and 12th month. The primary efficacy endpoint of this study was the rate of change in thyroid nodule volume from baseline at 6 months of treatment. The rate of change in thyroid nodule volume from baseline at 3 and 9 months of treatment was a secondary efficacy endpoint. Other secondary efficacy endpoints included maximum thyroid nodule diameter, number of thyroid nodules, proportion of patients with reduced thyroid nodule volume or ≥50% from baseline, thyroid volume, thyroid function (serum TSH, FT3, FT4, thyroid egg levels (Tg), thyroid antibody levels (TgAb, TPOAb), quality of life evaluation (SF-36), etc. Safety endpoints included incidence of AE/ serious adverse events (SAE), causality, and outcomes. Incidence of AE/SAE leading to discontinuation. Changes in safety laboratory test values from baseline.
This is a prospective, multi-center, single-arm target value clinical study to study the safety and effectiveness of Peripheral Scoring Drug-coated Balloon dilatation catheters in the treatment of hemodialysis arteriovenous fistula stenosis.
This project aims to establish the MERCURY pilot screening program as part of the "Love Lung Project," employing a novel concept of lung cancer screening with the assistance of low-dose computer tomography (LDCT). By using clinical pathology as the gold standard, it will parallelly compare the performance (with a sensitivity of ≥90%) of the MERCURY early lung cancer screening model against the LDCT-only screening group within the "Love Lung Project." Ultimately, the objective is to reduce the proportion of overtreatment, achieve earlier staging, and extend patient survival, thus enhancing clinical value.
This study was designed as a a single-center, randomized, open, interleaved (3-cycle, 3-sequence) trial. It is planned to enroll 18 healthy subjects.
This study aims to explore through a multi-center, randomized controlled clinical study whether robot-assisted radical resection of right colon cancer is superior to laparoscopic surgery in terms of surgical quality and oncological prognosis.
This study is a single-center, open-label, single-arm, dose-escalation trial. The aim of this study is to investigate the safety and efficacy of anti-CD19 CAR-NK cells in patients with refractory/relapsed systemic lupus erythematosus.
The goal of this clinical trial is to investigate the effect of perioperative administration of vitamin C on postoperative pulmonary complications, with the aim of providing a safe and effective medication regimen for the prevention and treatment of postoperative pulmonary complications in patients undergoing surgery for craniocerebral tumors. The main questions it aims to answer are: 1. To determine whether vitamin C can reduce pulmonary complications after surgery for intracranial tumors. 2. Does intraoperative vitamin C improve the prognosis of surgical patients Researchers will compare vitamin C to a placebo (saline) to see if vitamin C is effective for postoperative lung complications in patients undergoing surgery for cranial tumors. 1. Participants will be intravenously pumped with vitamin C for two hours after induction of anesthesia. 2. Participants will have intraoperative plasma sampling and recording of ventilator parameters, monitor parameters and perioperative data. 3. Participants will be followed up until discharge from the hospital to record symptoms and adverse events, and will be called at six months to check on their prognosis.
Purpose of the study To evaluate whether the clinical efficacy of submucosal injection of indocyanine green tracer laparoscopic gastric cancer lymph node dissection is superior to that of laparoscopic gastric cancer lymph node dissection without indocyanine green tracer in 3D fluorescence laparoscopic mode in patients with gastric adenocarcinoma (cT1-4a, N-/+, M0). To observe the role of submucosal injection of ICG for tumor localization in fluorescence 3D fluorescence laparoscopic surgery and the application of lymph node dissection in laparoscopic radical surgery for gastric cancer. Study design. Multicenter, randomized, open, parallel-controlled, superiority design. Subgroups Group A (experimental group): indocyanine green tracer 3D laparoscopic gastric cancer lymph node dissection group Group B (control group): no indocyanine green tracer 3D laparoscopic gastric cancer lymph node dissection group. Study population Patients who met all the inclusion criteria and did not fall into any of the exclusion criteria were eligible to enter this study. Randomization Patients were first evaluated preoperatively to determine that they could receive laparoscopic radical gastric cancer treatment and receive endoscopic indocyanine green labeling. Once the enrolled cases were determined to meet the admission criteria after laparoscopic exploration, they could be enrolled in this study for randomization. The central dynamic, stratified zone randomization method was used in this study, and the control factors considered were age, tumor site, and preoperative stage. Given the number of seeds and the length of the zones, SAS 9.2 programming was applied to generate the treatment allocation corresponding to the running number 484, which was deposited in the data center. A person at the participating research center was responsible for sending the enrolled case information (age, tumor site, and preoperative stage) to the randomization implementation department at the data center by email, phone, or SMS, and the contact person at each respective research center confirmed that the patient met the enrollment criteria, contacted the contact person for the assigned case in this study, and determined the enrollment of the case by further analyzing the case information, and at the same time, notified the contact person at the research center where the case was located The contact person of the research center where the case is located will be notified at the same time. Competitive enrollment was used in this study. Blinding.
