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.
Liwen procedure is generally safe and effective in treating hypertrophic cardiomyopathy, but a small proportion of patients have complications after the operation. The goal of this observational study is to explore the incidence of postoperative complications of the Liwen procedure in hypertrophic cardiomyopathy patients underwent Liwen procedure in Xijing Hospital. The main question it aims to answer are: - What is the incidence of complications in HCM patients underwent Liwen Procedure during postoperative hospitalization and a short-term follow-up period? - What is the relevant factors of complications in HCM patients who underwent Liwen Procedure during postoperative hospitalization and short-term follow-up period? Can the complications of surgical patients during postoperative hospitalization be predicted? Participants have been evaluated using a variety of medical examinations before they underwent Liwen Procedure. Variants collected from medical examination and case history were used to analyze the association with each postoperative complication.
Venetoclax is considered as a promising agent for light-chain (AL) amyloidosis due to the high percentage of t(11;14). Several retrospective studies showed venetoclax-based therapy could induce rapid and profound hematologic response in AL patients with favorable safety profile. As an oral agent with encouraging data, it is worth to prospectively evaluate the efficacy and safety of venetoclax in untreated AL amyloidosis patients.
There are no endoluminal stent systems available on the Chinese market for the effective treatment of aortic arch lesions (involving aortic arch aneurysms, aortic coarctation, aortic pseudoaneurysms, aortic ulcers, and intermural hematomas), and therefore this study is intended to be a prospective, single-arm study.
This study is a multi-center and cross-sectional study. Using standardized case report forms, we randomly selected suitable patients from the cognitive centers of provincial administrative units in Chinese mainland to conduct a questionnaire survey, so as to obtain relevant information about their economic burden.
The goal of this clinical trial is to test if PLB1001 works well and safely in Non-small cell lung cancer patients with MET exon 14 mutation. The main questions it aims to answer are: - If it is works well in Non-small cell lung cancer patients with MET exon 14 mutation - If it is safety and tolerant in Non-small cell lung cancer patients with MET exon 14 mutation Participants will 1. be given PLB1001 200mg BID,oral. 2. be received hematology and urine and ECG examinations every 14 days (First 3 months) or every 28 days (After 3 months) 3. be received Image examination every 8 weeks(First year) or every 12 weeks(After one year)
To verify the safety and effectiveness of transcatheter mitral valve clip delivery system and steerable guide catheter produced by Shanghai Shenqi Medical Technology Co., Ltd. in patients with moderate-severe (3 +) or severe (4 +) functional MR (functional MR) who still have symptoms after full treatment.
This study aimed to evaluate the feasibility and effectiveness of a nurse-led multidisciplinary precision care in early cardiac rehabilitation of patients with chronic heart failure, and further to promote the application of nurse-led multidisciplinary precision care.
Gastric signet ring cell carcinoma (GSRCC) possesses unique epidemiology and pathogenesis in the field of cancer, but its incidence is low. Unfortunately, there is currently a lack of systematic research focusing on the prognostic proteomic features of GSRCC. Given this knowledge gap, this study aims to comprehensively characterize the proteomic landscape of GSRCC using a reliable and reproducible DIA-PCT method. This study objectives include characterizing the heterogeneity of GSRCC, performing molecular typing, identifying potential biomarkers and therapeutic targets, and providing a resource for stratified analysis of GSRCC. To achieve these goals, the investigators selected a cohort of 112 GSRCC patients from a pool of over 10,000 gastric cancer patients and conducted a proteomic analysis using the DIA-PCT method. This meticulous approach revealed four novel proteomic subtypes of GSRCC, each exhibiting unique molecular characteristics. Additionally, the investigators discovered that PRDX2 and DDX27 can serve as predictive biomarkers for GSRCC, which were further validated in an independent cohort of 75 GSRCC patients. Furthermore, the investigators paid particular attention to the MLT-GSRCC subgroup and identified three distinct proteomic clusters among MLT-GSRCC patients. Subtype 2 within this subgroup demonstrated the poorest prognosis. Through a rigorous screening process, the investigators determined potential targets for the treatment of GSRCC. In conclusion, these findings contribute to the investigators understanding of the heterogeneity of GSRCC and provide valuable resources for future clinical stratification and targeted treatment strategies.
This is a multicenter, randomized, double-blind, parallel-controlled Phase III study to evaluate the efficacy and safety of TQB2440 injection/Perjeta® combined with trastuzumab and docetaxel in patients with early or locally advanced ER/ PR-negative HER2-positive breast cancer. The trial is scheduled to enroll 412 participants. The sample size was estimated based on 20 treatment cycles and 6 recurrence visits.
This project intends to include stage IA lung adenocarcinoma patients with CT imaging grboreal lesions; compare the results of lobectomy vs combined subsegmentectomy, and compare perioperative complications, differences in lung function and long-term outcomes between the two groups.
