China Pulmonary Vascular Disease Intervention Diagnosis and Management Study-right Heart Catheterization
Right heart catheterization(RHC) plays a crucial role in the diagnosis and treatment of pulmonary vascular diseases(PVD). In China, the lack of equipment and technical expertise has historically limited the implementation of RHC, thereby greatly restricting the diagnosis and treatment of RVD. In recent years, with improvements in these issues, more …
Changes in Ciprofol Dosage in Insomnia Patients Undergoing Digestive Endoscopy
To compare the dosage requirement of ciprofol during digestive endoscopy between patients with insomnia and those with normal sleep pattern.
A Multi-center Cohort Study of Hydatidiform Mole in China (CN-HM-01)
This observational study aims to establish a national cohort of patients with hydatidiform mole (molar pregnancy) to investigate its malignant transformation rate and malignant transformation mechanisms, with the goal of developing and promoting precision diagnosis and treatment models across China.
Value of Super-resolution Ultrasonography in Differentiating Benign and Malignant Lymph Nodes
Lymph nodes are one of the most important components of the human immune system, and superficial lymph node enlargement lacks specificity. Ultrasound examination has been widely used in the diagnosis of lymph node lesions and is of great significance in distinguishing between benign and malignant. However, the two-dimensional and Doppler …
Changes in Etomidate Dosage in Insomnia Patients Undergoing Digestive Endoscopy
To compare the dosage requirement of etomidate during digestive endoscopy between patients with insomnia and those with normal sleep pattern.
Differentiation of Benign and Malignant Pulmonary Nodules by Volatile Organic Compounds in Human Exhaled Breath
The goal of this observational study is to develop an advanced expiratory algorithm model utilizing exhaled breath volatile organic compound (VOC) markers. This model aims to accurately differentiate benign from malignant nodules in individuals harboring pulmonary nodules. The primary objectives it strives to accomplish are: To assess the diagnostic accuracy …
Development and Application of a Thrombosis Risk Prediction Model in Lung Cancer Patients Treated With Immune Checkpoint Inhibitors
The purpose of this observational study is to explore the incidence, risk factors, and relationship with therapeutic outcomes of VTE (venous thromboembolism) and ATE (arterial thromboembolism) associated with immune checkpoint inhibitors (ICIs) therapy. The primary questions it aims to address are: What is the real-world incidence of VTE/ATE in lung …
Development and Validation of an Ovarian Cancer Risk Prediction Model for Family Members of Ovarian Cancer Probands
Ovarian cancer is the gynecological malignancy with the highest fatality rate, seriously threatening the life and health of women. One of the main reasons for its high fatality rate is that approximately 70% of patients are diagnosed at an advanced stage. Fortunately, about 1/5 of ovarian cancers are associated with …
AI Detection of Bladder Tumors Under Endoscopy
The goal of this clinical trial is to learn if the AI algorithm can detect bladder tumors better than urologists under cystoscopy. It will also train the AI algorithm for bladder tumor detection. The main question it aims to answer is: Can AI algorithm achieve IOU value, precision, recall, false …
Risk Factors for Stroke or Systemic Embolism in Chinese Patients with Non-Valvular Atrial Fibrillation Registry
This study is aimed to validate the existing stroke risk stratification model for patients with atrial fibrillation (AF) (CHA2DS2-VASc Score, CHADS2 Score, ATRIA score, ABC score, etc.) and establish a new stroke risk assessment model using a nationwide AF -specific registry in China.
