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.
Rising thyroid carcinoma rates, with papillary thyroid carcinoma (PTC) as the main type (85-90% of cases), often show early cervical lymph node spread. This increases the risk of PTC patients for recurrence and death. A new study's multimodal model fuses preoperative US and cytology images to better predict lymph node metastasis, aiming to improve treatment plans, reduce unnecessary surgeries, and enhance patient outcomes.
Colorectal cancer is the third most common malignancy worldwide and the second leading cause of cancer-related death. About 70% of colorectal cancers develop through the adenoma-cancer pathway. Early detection and resection of colorectal neoplastic lesions significantly reduce the morbidity and mortality of colorectal cancers. Colonoscopy is considered to be the preferred method for screening for colorectal lesions. However, as the number of endoscopic resection increases, the costs associated with pathological diagnosis of endoscopic resection and resection specimens increase year by year. In clinical practice, it will be very important and urgent to correctly judge the nature of colorectal lesions to avoid pathological diagnosis and then realize optical biopsy. Therefore, to clarify the endoscopic diagnosis of colorectal lesions, many endoscopic techniques have been applied clinically. Such as narrow-band imaging, magnifying narrow-band imaging endoscopy, magnifying chromoendoscopy and endocytoscopy. Endocytoscopy has two modes, EC-NBI mode and EC-staining mode. EC-NBI mode is to observe the microvessel on the mucosal surface of colorectal mucosa after switching the endoscopy to NBI mode. EC-V pattern is used to observe microvessels and then endoscopic diagnosis is performed. The EC-staining mode was that the cell nuclei and glandular duct morphology of colorectal lesions could be observed by endocytoscopy after chemical staining. Endocytoscopic diagnosis is performed clinically after observation of glandular ducts and nuclei. However, current studies on the diagnostic value of endoscopy in colorectal lesions are all retrospective studies with small samples, and there is a lack of clinical studies based on chinese population. Therefore, our center intends to conduct a study of a large sample to explore the diagnostic value of endoscopy in colorectal lesions.
This study is an open-label, non-randomized, single-dose Phase 1/2 trial involving around 85 adult and pediatric participants aged between 2 and 50 years with sickle cell disease (SCD). It aims to assess the effectiveness of hematopoietic stem cell transplantation (HSCT) using BAH243 for SCD.
Gangrenous cholecystitis is the most common complication of acute cholecystitis. There is no research using machine learning models to construct predictive diagnostic models for gangrenous cholecystitis.
This study aims to explore the role of dagliflozin in preserving the residual renal function(RRF) in peritoneal dialysis (PD) patients.
Post-thoracotomy pain syndrome (PTPS) affects respiratory function, hindering sputum clearance and ventilation, and represents a significant complication of thoracic surgery. The analgesic effect of esketamine combined with butorphanol in PTPS is still unclear, so this study focused on this aspect.
This is a prospective, single-center, open-label, non-randomized controlled real-world study aimed at exploring a novel approach to cavity construction for thyroid endoscopic surgery. The study seeks to evaluate its effectiveness and safety while accumulating further evidence-based medical data. Three hundred patients with thyroid tumors were divided into an experimental group (150 cases receiving a new endoscopic thyroid surgery technique, namely, dual-port trans-subclavian thyroid endoscopic surgery) and a control group (150 cases undergoing traditional open thyroid surgery) according to their treatment intention. Laboratory and medical data from specified follow-up points are collected, and adverse events are recorded detailly. The primary efficacy endpoint is a comparison of surgical complications between the two treatment groups. Secondary endpoints include: (1) levels of IL-2, IL-4, IL-6, IL-10, TNF-α, INF-γ, renin, angiotensin II, and aldosterone preoperatively and on the second day postoperatively; (2) NRS scores on the first day postoperatively; (3) length of hospital stay, duration of surgery, total treatment cost, and postoperative drainage volume; and (4) assessment of wound satisfaction during a three-month follow-up visit. Safety assessments include adverse events, vital signs, and pathological examinations.
This is a multicenter, single-arm, two-part study designed to evaluate the safety and efficacy of Lutetium [177Lu] Oxyoctreotide Injection in patients with inoperable, locally advanced or metastatic, progressive, advanced somatostatin receptor (SSTR) positive neuroendocrine neoplasms (NEN) other than grade G1/G2 gastroenteropancreatic neuroendocrine tumors (GEP-NET).
The investigators conduct this phase II study to evaluate safety and effectiveness of EGCG in patients with dysphagia. Swallowing-related dysphagia and pain scores were recorded using the numerical rating scale (NRS) daily . Barium meal radiography was utilized to measure the luminal size and the length of the lesion area both before and after a week of EGCG treatment. The scales are translated into Chinese and guides in Chinese are developed instructing how to use the scales and perform the assessments.
This study is a single arm, open design aimed at evaluating the safety and tolerability of Autologous Tumor-Infiltrating Lymphocyte (GT307 injection ) for treatment of patients with solid tumours,while evaluating pharmacokinetic characteristics and efficacy assessment to determine the optimal biological dose (OBD).
