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.
Lumbar degenerative diseases such as lumbar disc herniation (LDH) and lumbar spinal stenosis (LSSS) are common and frequently encountered in orthopaedics. With the acceleration of the aging process of society, their incidence rate increases year by year. At present, conservative treatment is the preferred choice for this type of disease, and surgical treatment is feasible in cases where conservative treatment is ineffective. The main surgical methods include simple laminectomy and nucleus pulposus removal, intervertebral fusion and internal fixation, intervertebral disc replacement, and non fusion surgery. Simple nucleus pulposus removal surgery has drawbacks such as loss of intervertebral height and foramen height, which can affect spinal stability; Intervertebral fusion and internal fixation surgery has the problem of accelerating adjacent segment degeneration; The current therapeutic effect of lumbar disc replacement is not yet clear, and the technology is not yet mature. In response to the shortcomings of the above surgical methods, the advancement of science and technology has driven the development of spinal surgery, and a new surgical concept has emerged - spinal non fusion fixation technology. The INTRA-Spine dynamic stability system between vertebral lamina is one of the non fusion technologies of the spine. The core concept of this technology is to provide dynamic fixation on the basis of sufficient decompression of nerves, with the rotation center located between the vertebral lamina, which is closer to the normal movement center of the lumbar spine. It simulates the normal physiological structure of the lumbar spine with minimal damage and trauma, and maximizes the preservation of surgical segment mobility while maintaining spinal stability, Reducing stress concentration in adjacent segments caused by local fusion, thereby reducing the acceleration of adjacent segment degeneration, theoretically has good clinical and imaging efficacy.
This observational study aims to assess the performance of the software called ausculto™. ausculto™ is a collection of computer algorithms that intend to analyse heart sounds recorded from the built-in microphone of a smartphone for abnormal sounds. Participants will have their heart sounds recorded during their regular clinic appointment after consenting to participate in this study. Researchers will manually annotate the recorded heart sounds to create a database for use in future training and testing of artificial intelligence (AI) intended for medical uses.
This project intends to adopt the multicenter prospective real-world study method to conduct a preliminary study on the incidence, grading, risk factors, respiratory support strategies, in-hospital mortality, 3-month mortality, 6-month mortality, 1-year mortality, quality of life, lung function and limb function recovery, cognitive function, return to work and other conditions of ARDS patients in RICU. By collecting 1,000 patients, a clinical database related to ARDS in China was established to provide essential data and ideas for promoting standardized diagnosis and treatment technology for ARDS patients and further clinical intervention research. At the same time, ARDS biobank was established in China-Japan Hospital and Xiangya Hospital to realize the integration of clinical data and sample resources, and the prediction model of ARDS survival and complications of tuberculosis clinical data and biological samples was established by using big data and AI technology.
The general objective of this study is to evaluate the effect of 12-week microteaching training on the teaching skills level of university students majoring in physical education in China. The specific objective of this study is to examine the effect of microteaching training on verbal command, movement explanation, movement demonstration, diagnostic error correction, and organization and management skills of university students majoring in physical education in China. The participants will be divided into an experimental group and a control group. Microteaching and conventional training were used respectively to verify the influence of microteaching training on the teaching skills level of university students majoring in physical education in China.
Cerebral hyperperfusion syndrome (CHS) is one of the severe complication after carotid artery stenting with a high mortality rate. CHS was defined as cerebral hyperperfusion (CH) with clinical symptoms such as unilateral headache, convulsions, hemiparesis/hemiplegia, visual disturbances, ataxia, aphasia, while CH could be a disastrous outcome causing complication after carotid revascularization if not managed properly and timely. This is a single-center prospective cohort study to investigate the risks of CH after carotid artery stenting. All patients with severe carotid artery stenosis underwent carotid arterial ultrasonography and dynamic cerebral autoregulation (dCA) test by transcranial Doppler sonography (TCD) before operation. The postoperative carotid ultrasound and transcranial Doppler sonography (TCD) results are also needed. The investigators will collect this test data at 48h, 1 month and 3months after carotid artery stenting（CAS）. According to the examination results, they were divided into two groups: CH group and non-CH group. The investigators will collect data before CAS, on all participants' age, sex, heart rate, BP and end-tidal carbon dioxide (ET-CO2) and the following information from the patients : (i)demographic data, such as hypertension, coronary heart disease, diabetes, hyperlipidemia, smoking and body mass index; (ii) relevant clinical symptoms; (iii) preoperative colour Doppler ultrasonography（CDU）and transcranial Doppler sonography(TCD) results; (iv) The cerebral blood flow velocity (CBFV) of the middle cerebral artery（MCA） induced will be measured by non-invasively and continuously dCA test. This study could be aimed to analyze the factors influencing cerebral hyperperfusion after CAS. The purpose of this study will be to perform more precise risk stratification for high-risk CH patients and improve the quality of life of them. Statistical Analysis The Statistical Package for the Social Sciences（SPSS）software Version 26.0 (IBM, New York, USA) will be used for statistical analyses. The indicators with P < 0.2 in the univariate analysis will be entered into a logistic regression analysis to investigate the independent risk factors for CH after CAS. All tests will be performed two sided, and a P < 0.05 will be considered statistically significant.
This study is a randomized, double-blind, placebo-controlled, multicenter phase III clinical study to evaluate the efficacy and safety of carrelizumab plus concurrent chemoradiotherapy compared with placebo plus concurrent chemoradiotherapy in the treatment of patients with inoperably advanced esophageal cancer, and to explore the relationship between PD-L1 expression and efficacy in tumor tissues. Experimental group: carrelizumab in combination with concurrent chemoradiotherapy PD-1: carrelizumab: 200 mg/3W Chemotherapy: Paclitaxel: 50 mg/m2/W Cisplatin: 25mg/m2/W Radiotherapy: 50.4 Gy / 28 f Chemotherapy drugs are used for 5 cycles, and carrelibizumab is used for up to 24 months until PD or is intolerable Control group: placebo-resistant in combination with chemoradiotherapy placebo: 200 mg/3 W Chemotherapy: Paclitaxel: 50 mg/m2/W Cisplatin: 25mg/m2/W Radiotherapy: 50.4 Gy / 28 f Chemotherapy drugs are used for 5 cycles, and carrelibizumab is used for up to 24 months until PD or is intolerable
The research subjects of this project are mainly aimed at patients with locally advanced esophageal cancer who cannot be treated surgically, in Taixinsheng 3 months after the end of concurrent chemoradiotherapy, RECIST is pressed as based on physical examination and esophageal barium dialysis or esophageal contrast-enhanced CT Criteria assessed short-term and long-term efficacy separately. By detecting the expression of EGFR in patients with locally advanced esophageal cancer, the relationship between the efficacy of EGFR monoclonal antibody therapy and the long-term prognosis of patients was evaluated. Evaluation of safety, toxicity and side effects during treatment and in the near and long term.
The goal of this clinical trial is to compare in newly diagnosed patients with resectable rectal cancer with lateral lymph node metastasis. This study aims to - further verify the safety and efficacy of FOLFOXIRI three-drug regimen - Using multiple omics techniques to identify and confirm specific molecular markers Participants will be treated with FOLFOXIRI three-drug combination regimen.
