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.
Since the outbreak of COVID-19, students; sports environment and time have been severely compressed, which has had an unprecedented impact on their physical fitness and sports learning attitude. Therefore, it is urgent to adopt an effective teaching mode that aligns with curriculum reform to improve students; physical quality and learning attitude. The Sports Education Model is one of the most popular teaching models in Western developed countries, but the application in China and the related evidence of improving students; physical quality and learning attitude towards sports are relatively scarce. This study compares and analyzes the influence of the Sports Education Model and Traditional Teaching on junior middle school students; physical fitness and learning attitude, aiming to provide theoretical support for improving students; physical fitness and learning attitude and promoting the Sports Education Model in China. Promote the healthy development of junior middle school students.
To assess the 6-months effects and safety of stellate ganglion block(SGB) for Chronic Migraine (CM) patients who failure to undergo preventive therapy and are seeking a more suitable non-pharmacological therapy.
The purpose of this study was to evaluate the effectiveness of early administration of BXOS110 for injection in reducing overall disability in patients with acute ischaemic stroke.
Quantitative flow reserve (QFR), derived from coronary angiography, has shown high accuracy in detecting significant lesions. Ultrasonic flow ratio (UFR), a new development from IVUS, integrates physiological estimation with intravascular imaging. Although both QFR and UFR are effective, there's no conclusive evidence favoring one over the other. The study aims to compare UFR and QFR's diagnostic performance against the conventional FFR standard in detecting significant coronary lesions.
This study was designed as multi-center, ambispective observational trial to evaluate the efficacy and safety of addition of cetuximab to doublet or triplet chemotherapy as conversion therapy in right-sided BRAF/RAS wild-type CRLM with curative intent. The primary endpoint was radical resection rate (R0). The secondary endpoint was response rate, rate of NED, depth of remission, early tumor shrinkage, progression free survival and safety.
This study is aim to evaluate the preliminary efficacy of GH21 combined with previous target therapy or immunotherapy in patients with advanced solid tumors.
The current study provided an initial investigation of the effect of self-compassion on reducing materialism and explored the basic psychological needs and self-esteem as potential mechanisms. Two studies would be conducted. Study 1 explored the relationships among variables with cross-sectional data, to explore the relationship between self-compassion and materialism, and test the mediating role of basic psychological needs and self-esteem. Study 2 developed a new online self-help self-compassion intervention and conducted a randomized control trial (i.e., intervention group and waitlist group) to further explore the casual effect of self-compassion on materialism, with the mediating effect of basic psychological needs and self-esteem.
The investigators aim to explore a new EBV DNA surveillance method with both high sensitivity and specificity in nasopharyngeal carcinoma (NPC) patients. the investigators aim to conduct plasma EBV DNA counting by next generation sequencing (NGS) in non-metastatic NPC patients on their diagnose, after two cycles of induction chemotherapy (IC), and 4-8 weeks after definitive radiotherapy. The investigators aim to explore whether sequencing-based counting is better than PCR analysis in plasma EBV-DNA surveillance, so as to monitoring tumor responses to treatment and for guiding individualized treatment adaptation in the future.
Background: Accurate labeling of obstruction site on upright abdominal radiograph is a challenging task. The lack of ground truth leads to poor performance on supervised learning models. To address this issue, self-supervised learning (SSL) is proposed to classify normal, small bowel obstruction (SBO), and large bowel obstruction (LBO) radiographs using a few confirmed samples. Methods: A few number of confirmed and a large number of unlabeled radiographs were categorized based on the ground truth. The SSL model was firstly trained on the unlabeled radiographs, and then fine-tuned on the confirmed radiographs. ResNet50 and VGG16 were used for the embedded base encoders, whose weights and parameters were adjusted during training process. Furthermore, it was tested on an independent dataset, compared with supervised learning models and human interpreters. Finally, the t-SNE and Grad-CAM were used to visualize the model's interpretation.
The goal of this observational study is to learn about the clinical characteristics and construction of a predictive model in elderly COVID-19 patients. The main question it aims to answer is the main clinical characteristics and risk factors of elderly COVID-19 patients. Participants will not be asked to do any other intervening measure.
