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.
Fat infiltration and atrophy of lumbar muscles are related to spinal degenerative conditions, which can be seen reliably on MRI scans of lumbar disc herniation (LDH) patients. The aim of this study was to investigate the relationship between the degeneration of core muscles, obesity and chronic LDH. Fifty-five healthy volunteers and fifty-five chronic LDH patients (the course of the disease is more than six months) were enrolled. Core muscle percent fat and subcutaneous fat tissue thickness(SFTT) were used as the outcome measure, and logistic regression and independent samples t-test as the analytical methods to compare the relationship of the following five independent variables (erector spinae, rectus abdominis, [transversus abdominal, internal abdominal oblique, and external abdominal oblique muscle], lumbar multifidus, and psoas major muscles) and SFTT with LDH.
This study was designed to be a retrospective, multicentre, observational study to evaluate the efficacy and safety of dupilumab in the treatment of bullous pemphigoid and to find predictors of efficacy.
It is uncertain whether vitD3 supplementation is beneficial for the remission of ulcerative colitis (UC). The effects of vitD3 supplements on the efficacy of vidrecizumab in Chinese UC patients were retrospectively analyzed. Methods: Patients with moderate to severe UC were recorded. These patients were initially treated with VDZ. VitD3 supplementation was defined as 400IU/d vitD3 supplementation during the first infusion of VDZ and continued throughout the follow-up period. Disease activity was assessed using the modified Mayo score.
Adequate quality of bowel preparation(BP) is essential for colonoscopy. In recently, Kang suggested that for low-risk patients, single dose of 2L PEG is an effective regimen for bowel preparation.However, due to the poor palatability, there still more than 30% patients with 2L regimen experienced nausea or vomiting in our center. Oral lactulose is a treatment for constipation. Several studies have compared the effectiveness between use PEG and lactulose for colonoscopy preparation in average-risk patients. However, the data in low-risk patients is vacant. The objective of current study was to compared the effectiveness of bowel preparation and patient tolerance using lactulose and 2L PEG regimen in low-risk patients.
This study will help to identify the causes of new epilepsy and provide a basis for the development of a rational and standardized diagnosis and treatment plan to reduce the rate of disability and death.
More than 2 million patients worldwide receive heart surgery every year, majority of these surgical patients will undergo cardiopulmonary bypass. However, the incidence of postoperative acute lung injury due to cardiopulmonary bypass is still as high as 20% to 35%. According to clinical experience, the earlier lung damage is detected, the more successful the treatment will be. On the basis of traditional detection, the investigators found a new indicator, serum soluble vascular endothelial-cadherin, which are easy to obtain and have certain specificity. Importantly, they can predict postoperative acute lung injury within 1 hour after cardiac surgery. It is meaningful that this indicator can provide clinicians with early decision-making advice and immediate treatment for patients who may be at risk.
A random, blind and positive control design was adopted.the investigators will assess the safety and immunogenicity of 2 doses of an quadrivalent influenza vaccine virus subunit in children aged 6 to 35 months. A total of 2,772 subjects in the 6-35 month age group were randomly divided into experimental vaccine 1, experimental vaccine 2 and control vaccine groups at a ratio of 1:1:1, and received the corresponding vaccine respectively. 2 doses in the whole course, 28 days apart. Safety observation: All subjects received 30 minutes of immediate response observation after each dose of vaccine and 0-7 days of systematic active safety observation; After 7 days of vaccination, the incidence of adverse events was observed by combining regular weekly follow-up with subject's voluntary report. Safety observation was conducted for 0-28/30 days after each dose of vaccine. Serious adverse events (SAE) were collected within 6 months after the first dose was administered. Immunogenicity observation: Blood samples were collected before the first dose and 28 days after the full dose for influenza virus HI antibody detection. Observation of immune persistence: Blood samples of 3 and 6 months after immunity were collected for influenza virus HI antibody detection.
Consecutive patients suffering from gastric phytobezoars were divided into 3 groups (Group 1, Group 2 and Group 3) according to the phytobezoars' formation time and each group was further subdivided into control and intervention group according to whether Coca-Cola was admitted. All patients in intervention group dieted Coca-Cola whereas patients in control group refused to drink Coca-Cola and had willing to receive the emergently gastric fragmentation.
Stroke volume variation (SVV) and pulse pressure variation (PPV) have been thought to be sensitive predictors of fluid responsiveness in mechanically ventilated participants. In this paper, the investigators reported a special group of people to use SVV and PPV during their operation. The maintenance of hemodynamic stability and the critical organ perfusion is crucial to the treatment for patients with artificial Pneumothorax during esophageal surgery, because artificial pneumothorax causes incomplete ventilation of one lung. In addition, artificial pneumothorax may seriously affect theparticipant's heart and lung function, brings more challenges to the intraoperative anesthetic management, expecially in volume management. Little information is available about the accuracy of SVV and PPV to predict fluid responsiveness in participants with artificial Pneumothorax during esophageal surgery. It is unclear whether it will affect the accuracy of SVV and PPV, and whether it will cause the change of their threshold values. The investigators will discuss it in the passage and the investigators will give an preliminary mechanism to explain the results.
1. In this study, the risk factors leading to catheter-related complications in the daily life behavior habits of patients with PICC catheter were identified, refined and initially established, and the Delphi method (expert consultation method) was used to further identify the existing and potential risk factors leading to PICC catheter-related complications in the daily life behavior habits of patients. To develop individualized and precise health education programs for risk factors, in order to build an accurate health education model centered on improving patients' daily life and behavior habits. 2. To conduct clinical empirical study to evaluate the feasibility and effectiveness of precise health education program for PICC patients with catheter, and to observe the impact of this health education model on the knowledge, attitude and practice level of daily management, self-management efficacy and the incidence of related complications after catheter insertion in PICC patients, so as to provide a reference for health education of PICC patients.
