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.
The goal of this observational study is to learn about emergency responder in different states. The main questions it aims to answer are: - Ten vital signs and behavioral parameters in different states (quiet, after post, after physical training) including: respiratory rate, pulse rate, oxygen saturation, body position, chest and abdominal respiratory movements, electromyography (EMG), electroencephalogram (EEG), partial pressure of end-expiratory CO2 concentration, partial pressure of transcutaneous oxygen, and partial pressure of transcutaneous carbon dioxide. - Eight vital signs and behavioral parameters in different environments (altitude, confined space, energized work, job site) including: respiratory rate, pulse rate, oxygen saturation, body position, chest and abdominal respiratory movements, electromyography (EMG), electroencephalogram (EEG), and partial pressure of end-expiratory CO2 concentration. Participants will normal operating conditions, the researcher collects vital sign information.
To investigate the effect of transcranial oscillatory direct current stimulation on functions of cerebral cortex (cortical excitability and frequency of eeg) in healthy subjects
Lumbar degenerative disease is one of the most common diseases in orthopedic and spinal surgery. The pathogenesis of lumbar degenerative disease is still unclear, mainly including aging degeneration and biomechanical hypothesis. In our previous research work，the investigators took lumbar disc tissue from patients who underthe investigatorsnt surgical treatment for lumbar degenerative diseases. The investigators found that some patients had low-toxic bacterial infection in the intervertebral disc tissue. Combined with literature and previous studies, it is suggested that microbial infection plays a role in lumbar degenerative diseases. The investigators suggest that microbial infection may be closely related to the occurrence and development of lumbar degenerative diseases, which may cause or even accelerate the degeneration of lumbar intervertebral disc tissue. The current research difficulties are as follows: 1. Low sensitivity and specificity of microbial analysis; 2. It is difficult to distinguish the colonization infection of intervertebral disc tissue microorganisms from the contamination of foreign substances. In view of this, this study intends to use the high-throughput gene sequencing technology of infectious pathogens based on nano single molecule sequencing, double verification of blood samples and intervertebral disc tissue samples, to identify the microbial status of degenerative lumbar disc tissue, and to explore the correlation between lumbar degenerative disease and microbial infection, identifying relevant susceptible microorganisms, which is expected to study the pathogenesis of this susceptible microorganism in the future, and provide new ideas and approaches for the prevention, control and treatment of lumbar degenerative diseases.
The goal of this observational study is to compare the effectiveness and efficiency for precaution of severe hyperbilirubinemia in neonate by different follow-up methods of neonatal jaundice. There are two kinds of follow-up methods in the investigators clinical practice. The one is internet plus follow-up model, the other is conventional clinic follow-up method. Parents of the participant neonates can choose one by themselves. After parents of the participant signed informed consent, the investigators recorded several information including severe hyperbilirubinemia, length of phototherapy, follow-up times, et al. Then the investigators analysed these data in order to know what kind of follow-up method is better to prevent severe hyperbilirubinemia and more easy to be accepted.
Part Ⅰ:Infrared thermograms of four parts of the soles of the feet, dorsum of the feet, palms of the hands, and dorsum of the hands of healthy volunteers, diabetic patients, and patients with diabetic peripheral neuropathy were collected by using infrared thermography, and the patterns of change in the average temperatures of the parts of the participants in the three groups were analysed and compared by using the accompanying software. Part Ⅱ: Diabetic Peripheral Neuropathy (DPN) mainly presents with symmetrical pain,numbness, and ankylosing sensation, but reversal after diagnosis is particularly difficult. Electroacupuncture can significantly improve the function of peripheral nerves, regulate local blood flow, and reduce the inflammatory response to promote nerve regeneration, but no study has shown that electroacupuncture can effectively prevent the occurrence of DPN. Therefore, it is of great research significance to determine whether electroacupuncture has the possibility in preventing the occurrence of DPN.
Iodine as an essential trace element for human, both excessive and insufficient intake would be harmful for human health. As susceptible population, children will be more sensitive to adverse effects caused by inadequate intake of iodine since they are at the peak of growth and development. Meanwhile, there are few direct evidence to establish dietary intakes levels of iodine for 3-6 years old pre-school children.
This study aims to investigate the clinical efficacy and associated immune and inflammatory mechanisms in patients with malignant tumors of spleen deficiency and dampness resistance type, by applying pricking therapy and wheat grain moxibustion on the back shu points or positive reaction points.
The aim of this study is to evaluate the efficacy and safety of PARP Inhibition and programmed cell death protein-1 (PD-1) blockade immunotherapy with concurrent stereotactic body radiotherapy (SBRT) for metastatic or advanced bone and soft tissue sarcoma.
Gallstone is a common disease in China.At present, the prevalence of gallstones in China is 15 %, and about 210 million people are sick. Acute cholecystitis is acute gallbladder inflammation, is one of the main complications of cholelithiasis or gallstones. The removal of gallbladder and gallstones in patients with acute cholecystitis in the presence of biliary pain will prevent the recurrence of gallbladder and reduce the risk of cholecystitis progression. If gallbladder perforation is not treated in time, the mortality rate is 30 %. Acute acalculous cholecystitis without treatment will be life-threatening, with a mortality rate of up to 50 %. At present, the vast majority of patients with acute cholecystitis are treated with 4-hole traditional laparoscopic cholecystectomy and open cholecystectomy. Their postoperative quality of life, pain and scar-related complications, remain major factors for patients.In recent years, with the renewal of the concept of minimally invasive surgery and the continuous advancement of instruments and technology, single-incision laparoscopic cholecystectomy has also maximized the quality of life after surgery and reduced postoperative pain and scar-related complications. At present, there are few reports on randomized controlled clinical trials of SILC in patients with acute cholecystitis, and there is a lack of large sample size studies.Due to the difficulty of SILC operation, the longer learning curve, the different equipment conditions and technical characteristics of each center, and the lack of standardized training, there is no effective consensus on the application indications and operation procedures of SILC in acute cholecystitis surgery. Based on the current status, the purpose of this study was to investigate the effect of SILC on postoperative quality of life, postoperative pain, scar assessment and postoperative complications in patients with acute cholecystitis, so as to propose a standardized single incision laparoscopic operation procedure in the treatment of acute cholecystitis.
The purpose of this study is to evaluate sacituzumab tirumotecan versus chemotherapy (docetaxel or pemetrexed) for the treatment of previously-treated non-small cell lung cancer (NSCLC) with exon 19del or exon 21 L858R EGFR mutations (hereafter referred to as EGFR mutations or EGFR-mutated) or any of the follow genomic alterations: ALK gene rearrangements, ROS1 rearrangements, BRAF V600E mutations, NTRK gene fusions, MET exon 14 skipping mutations, RET rearrangements, or less common EGFR point mutations of exon 20 S768I, exon 21 L861Q, or exon 18 G719X mutations. The primary hypotheses are that sacituzumab tirumotecan is: (1) superior to chemotherapy with respect to progression-free survival (PFS) per RECIST 1.1 as assessed by BICR in NSCLC with EGFR mutations; and (2) superior to chemotherapy with respect to overall survival (OS) in NSCLC with EGFR mutations.
