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.
Bronchial asthma is the most common chronic respiratory disease in children. At present, more attention has been paid to the treatment of airway inflammation and smooth muscle spasm, while the related research on the risk factors of asthma attack, mucus plug formation and its effect on asthma has been ignored. This study was a retrospective study. Children hospitalized for acute exacerbation of asthma from 2016 to 2021 were selected as the research objects. The clinical manifestations, bronchoscopy results and lung CT results of children hospitalized for acute exacerbation of asthma were summarized. To analyze the risk factors of acute exacerbation, clinical characteristics, risk factors of mucus plug formation in hospitalized children with asthma, and the safety and efficacy of flexible bronchoscopy in the diagnosis and treatment of hospitalized children with asthma. The discharged children were investigated by written or online questionnaires to understand the acute attack of asthma, control level, compliance, appliability of the China Children's Asthma Action Plan, family management and medical utilization of children with asthma after discharge.
The goal of this clinical trial is to compare in the efficacy and safety of Nd:YAG laser vitreolysis for symptomatic vitreous floaters. The main question it aims to answer are: • examine the efficacy and safety in treating early onset of vitreous floaters （Weiss ring） using Nd:YAG laser vitreolysis. Participants with symptomatic floaters for one month will be randomly divided into two groups：early treatment group and delayed treatment group. Participants in the early treatment group will receive a YAG laser vitreolysis immediately and a sham laser treatment three months later, while participants in the delayed treatment group will receive a sham laser treatment immediately and a YAG laser vitreolysis three months late. Researchers will compare the two groups to see the efficacy and safety of early YAG laser vitreolysis for symptomatic vitreous floaters.
Phase II, single-arm, open-label single center study that assess clinical feasibility and safety of 3 cycles neoadjuvant Toripalimab plus chemotherapy in rare mutations stage IIB-IIIB NSCLC followed by optional adjuvant treatment upon investigators' decisions.
Objective:Patients with asymptomatic or minimally symptomatic Stage IV EGFR-positive NSCLC with baseline intracranial metastases. Aim: To investigate the timing, efficacy and safety of radiotherapy in patients with EGFR positive brain metastases treated with armatinib alone or combined with stereotactic radiotherapy. Method: Almonertinib: specification 55mg/tablet; The dosage is 110 mg / day (2 tablets / day) orally once a day; SBRT: 3-5 doses of 27-40 Gy
This is a prospective, single-arm, clinical study to explore the efficacy and safety of Axi-cel retreatment in R/R LBCL in Shanghai Ruijin Hospital in China. R/R LBCL patients who treated with Axi-cel got non-CR or relapsed were eligible for Axi-cel retreatment in this study. Patients will receive the standard dose of Axi-cel and follow the standard process. Other related treatment like bridging therapy or combination therapy will be based on patients status and investigators' decision. The primary endpoint is ORR, the secondary endpoint is CR, PR, DOR, PFS, OS and AE. A total of 32 patients is planned to be enrolled in this study. The trial will not go on if nobody got CR or PR in first 6 patients.
This study is a randomized, open, parallel controlled clinical trial. The main purpose of this study was to compare the changes in body weight/body mass index (BMI) before and after treatment between the two groups of patients with NST full-course nutritional management and without NST full-course nutritional management. The secondary objective was to compare the quality of life, nutritional status, immune function and inflammatory response, adverse reactions of radiotherapy and chemotherapy, and short-term/long-term efficacy between the two groups. The treatment plan was: esophageal cancer with routine nutrition guidance as the control group, and the NST whole-process intervention guidance as the experimental group. 1. Experimental group: NST whole-course intervention 1. Nutritionists formulate nutritional programs and manage them in a refined manner. On the basis of the patient's natural diet (food and homogenate meal), enteral nutritional preparations or parenteral nutritional supplements are given according to the patient's gastrointestinal obstruction, dietary structure, and food intake. Energy 30-35kcal/kg/d, protein 1.2-1.5g/kg/d. Enteral nutrition administration route: oral or tube feeding or ostomy, oral feeding is preferred; severe obstruction of eating or oral can not meet the target nutrition, choose tube feeding or ostomy. When it is expected that enteral nutrition cannot meet 60% of the target energy requirement for 3 to 5 days, choose parenteral nutrition. The enteral nutritional preparation adopts the whole protein enteral nutritional preparation Nengquan, and/or the tumor nutritional preparation Ruineng, and/or whey protein powder. 2. Radiotherapy 3. Chemotherapy 2. Control group: routine nutrition guidance for esophageal cancer (1) Nutritional therapy: The nutritional program was the same as that of the experimental group, and the patients performed it themselves. (2) Concurrent chemoradiotherapy: the same as the experimental group. Efficacy evaluation: 1. Body weight and body mass index (BMI) 2. Quality of life score (EORTCQLQ-C30) 3. Nutritional status 4. Immune function and inflammatory response (total lymphocytes, CRP, IL-6) (4) Intestinal mucosal barrier and intestinal flora (5) Adverse reactions of radiotherapy and chemotherapy (6) Short-term/long-term efficacy (5) Evaluation of treatment side effects (6) Short-term/long-term efficacy
Coronary calcified lesion is associated with a poor clinical outcome. Intravascular ultrasound (IVUS) provides anatomic information in detail about reference vessel dimensions and lesion characteristics including severity of diameter stenosis, lesion length, and morphology. Both randomized and observational studies have reported the clinical benefits of IVUS guidance for patients with chronic total occlusion (CTO), long lesions, acute coronary syndrome (ACS) with complex bifurcation lesions. Our previous ULTIMATE trial has demonstrated that IVUS-guided drug-eluting stent (DES) implantation significantly improved clinical outcome in all-comers, particularly for patients who had an IVUS-defined optimal procedure, compared with angiography guidance. However, the benefit of IVUS guidance in coronary severe calcification still remains unknown in the modern DES era.
The goal of this clinical trial is to investigate the use of TEAS on female patients with dysmenorrhea. The main questions it aims to answer are: Questions 1：Effect of TEAS on dysmenorrhea Questions 2：Mechanism of TEAS in treatment of dysmenorrhea Participants will wear TEAS devices to treat dysmenorrhea during menstruation The participants in the control group were treated with oral medication for dysmenorrhea
This is an open-label, muticenter phase II study to evaluate the efficacy and safety of QL1706 monotherapy or in combination with bevacizumab and XELOX as first-line treatment of unresectable advanced or metastatic CRC.
The objective of this trial is to evaluate the safety and effectiveness of Targeted Lung Denervation (TLD) for COPD patients using the lung denervation radiofrequency ablation device.
