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 clinical trial is to compare XELOX +Bev +Tislelizumab with standard chemotherapy，in MSS/pMMR-type RAS-mutated metastatic colorectal adenocarcinoma. The main questions it aims to answer are efficacy and safety of the regimen of XELOX +Bev +Tislelizumab. The investigators want to transform ras-mutated colorectal cancer into a "hot tumor" through the combination of anti-vascular therapy and chemotherapy, and then achieve better therapeutic effect through the combination with immunotherapy. Participants will receive the regimen of XELOX +Bev +Tislelizumab.

Background: Migraine is a common neurological disorder that also has a significant prevalence in children. Although the exact etiology of migraine is unknown, recent studies suggest an association between intestinal flora and migraine, and tryptophan metabolism is an important link between intestinal flora and the nervous system. However, the role of tryptophan metabolites in childhood migraine is not fully understood. Therefore, the aim of this study was to investigate the specific role of tryptophan metabolites in childhood migraine. Study objectives: The main objectives of this study were to assess the changes in tryptophan metabolites in childhood migraine and to explore their relationship with migraine attacks. Specific objectives include: 1. to determine the differences in tryptophan metabolites between children with migraine and healthy children; 2. to explore the correlation between tryptophan metabolites and migraine attacks 3. to assess the potential mechanisms of the role of tryptophan metabolites in childhood migraine. Study methods: 1. participant recruitment: a certain number of pediatric migraine patients and healthy children were recruited as controls. 2. data collection: clinical information, medical history, and blood samples were collected from participants. 3. Tryptophan metabolite analysis: using appropriate experimental techniques, ELISA Statistical analysis: The main analyses included the following: 1. comparison of differences in tryptophan metabolites between migraine and control groups, using t-test or Wilcoxon rank sum test. 2. To assess the value of tryptophan metabolites in the diagnosis of migraine, ROC curve analysis was used to calculate the sensitivity, specificity, and AUC. 3. To explore the factors associated with tryptophan metabolites and migraine, multiple logistic regression analysis was used to assess the risk and protective effects of each factor on migraine. Experimental hypothesis: Our experimental hypothesis was that tryptophan metabolites may play a key role in the pathogenesis of childhood migraine, particularly kynurenine (KYN), quinolinic acid (QUINA), and kynurenic acid (KYNA). We hypothesized that in pediatric migraine patients, the concentrations of tryptophan metabolites would change significantly compared to healthy children. We further hypothesized that the concentrations of certain tryptophan metabolites correlate with the frequency and severity of migraine attacks. Based on these hypotheses, our study will examine tryptophan metabolite concentrations in blood samples and perform a comparative analysis between pediatric migraineurs and healthy children. We will also explore the correlation between tryptophan metabolites and migraine attacks and determine their risk and protective role in childhood migraine through multiple logistic regression analysis. Outlook: The results of this study are expected to reveal the important role of tryptophan metabolites in the pathogenesis of migraine in children and provide a new basis for the diagnosis and treatment of migraine in children. In addition, the study may also provide theoretical support for the development of relevant therapeutic strategies and interventions, and provide new ideas for the prevention and management of migraine in children.
Venous thromboembolism (VTE) is one of the most common complications in perioperative period and the most common cause of postoperative death. VTE includes deep vein thrombosis (DVT) and acute pulmonary thromboembolism (PTE). Since the embolus of PTE comes from the deep vein thrombosis, and not all PE patients can present obvious clinical symptoms, VTE is currently considered as a disease for research, prevention, diagnosis and treatment at home and abroad. Therefore, we urgently need to develop a more comprehensive and reliable perioperative VTE risk prevention system based on medical big data and multi-module computer in current clinical practice, so as to effectively guide the prevention of DVT/PE, and thus reduce the perioperative mortality.
The purpose of this study is to study the performance of MRD monitoring in predicting the efficacy and prognosis of neoadjuvant therapy in patients with rectal cancer, and to explore the value of MRD detection in evaluating the prognosis of patients. In this prospective study, 50 patients with stage II-III rectal cancer who are planing to receive neoadjuvant chemoradiotherapy will be enrolled. The tumor tissue will be collected by colonoscopy before treatment and blood samples will be collected before treatment and during treatment.The whole blood samples will receive MRD detection. The change rate and clearance rate of MRD during treatment will be calculated, and will be associated with imaging efficacy evaluation, pathological efficacy evaluation,and prognosis, to determine the performance of MRD in predicting and judging the efficacy of neoadjuvant chemoradiotherapy and postoperative recurrence of rectal cancer.
