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.
Allergic asthma being the most widespread and easily identifiable phenotype, accounting for 60-80% of cases.Previous studies have reported that nearly 90% of patients with severe asthma were cases of allergic asthma, in which Immunoglobulin E (IgE) plays a critical role.Omalizumab was approved as an anti-IgE humanized monoclonal antibody for the treatment of patients with poorly controlled moderate-to-severe asthma, and was the first targeted drug used in the field of asthma treatment.The drug was launched in mainland China in August 2017.whereas,the clinical application experience, effects, and relevant data in the domestic population still lacking.The aim of this study was to observe the efficacy and safety of omalizumab, and to investigate whether baseline clinical characteristics and biomarkers can predicted response and adherence to treatment.
Analyze the correlation between the conformity of the anatomy (based on endoscopic examination) and postoperative anastomotic fistula and anastomotic stenosis; establish an anastomotic classification; and construct a predictive model combined with perioperative-related test indicators to provide more accurate risk assessment for clinical practice. Analyze the natural recovery process of postoperative recurrent laryngeal nerve injury in esophageal cancer by tracking vocal cord movement (based on endoscopic examination) and hoarseness symptoms; combined with perioperative related surgical and laboratory indicators, identify the relevant risk factors associated with delayed recovery of recurrent laryngeal nerve injury.
The purpose of the study is to evaluate the efficacy and safety of rezvilutamide in combination with androgen deprivation therapy (ADT) in participants with androgen receptor (AR) positive, high-risk salivary duct carcinoma (SDC). The procedures include screening, treatment and follow-up period. The treatment includes rezvilutamide plus Luteinizing Hormone Releasing Hormone agonist (LHRHa) for up to 2 years.
The impact of albumin administration in cirrhotics with acute variceal hemorrhage (AVH) is controversial. We aim to investigate the short-term rebleeding risk associated with albumin administration in a retrospective study of hospitalized cirrhotics with AVH with stable hemodynamics. This retrospective analysis includes clinical data of cirrhosis patients with acute variceal bleeding admitted to our hospital from January 2021 to October 2023. Propensity score matching will be performed to account for potential confounders associated with albumin use for outcome analysis. According to the outcome, patients will be divided into rebleeding group and non-rebleeding group. To investigate the impact of albumin infusion on the rebleeding risk in the propensity-matched cohort, patients will be divided into albumin user group and albumin non-user group. The primary outcome is the rebleeding risk within 30 days after discharge.
The goal of this clinical trial is to verify the effectiveness and safety of the low load blood flow restriction training program. The intervention effect, tolerance and compliance of low load blood flow restriction training and progressive resistance training on lung cancer patients complicated with sarcopenia during chemotherapy will be compared, in order to provide new ideas for improving or reversing sarcopenia. The main questions it aims to answer are: Can low load blood flow restriction training improve sarcopenia in chemotherapy induced lung cancer patients? Which training method is more effective and tolerable between low load blood flow restriction training and progressive resistance training? Participants will be randomly divided into 3 groups： 1. Routine care group (Control group, CON): The researchers will provide participants with regular exercise and dietary guidance. 2. Low load blood flow restriction group (LL-BFRT): The researchers will provide participants with a low load blood flow restriction training program constructed by our research group. 3. Progressive resistance training group (PRE): The researchers will provide participants with progressive resistance training.
The DNA methylation targets in preoperative plasma samples of the subjects will be detected by the multi-gene methylation test (ColonAiQ), and the test accuracy will be evaluated by compared with the clinical diagnosis evidence.
The loss of skeletal muscle mass and function usually occurs with aging, known as primary sarcopenia. Sarcopenia has a prevalence of 11.6% among the elderly population in China and is closely associated with increased risks of falls, disability, and mortality. Currently, there is a lack of definition criteria for sarcopenia based on biomarkers. The Gut-Muscle Axis hypothesis suggests a complex interplay between gut microbiota and skeletal muscle. Nutritional intervention targeting the gut microbiota potentially plays a significant role in muscle regeneration. Therefore, this study aims to explore the effects of symbiotic and whey protein on muscle, gut microbiota, and clinical outcomes among sarcopenia patients, to provide a reference for further diagnosis and treatment of sarcopenia.
This study aims to evaluate the effect of probiotics 7 days before cesarean section (CS) on postoperative recovery and the change of gut microbiota in pregnant women. Samples were obtained from a total of 80 pregnant individuals, divided into control group and probiotics group. Anal exhaust time and first defecating time were set as the primary outcome of recovery of CS. 16S rRNA amplicon sequencing of the V4 region was analyzed to evaluate the composition of them.
The efficacy of three different alimentary reconstruction methods after proximal gastrectomy will be investigated in this study in a prospective, multicenter, randomized controlled trial.
Dental anxiety is a common problem in dental care. The aim of this protocol is to evaluate the effect of orange and tea essential oil for the control of anxiety and pain in adults during dental treatments.
