Filter by:The investigators will try to evaluate the effects of substitution of dietary animal protein by black soybean milk (400 mL x 2) per day on anthropocentric and metabolic parameters in obese subjects.
To evaluate the correlation between gut microbiota and metabolites in Borrmann type IV gastric cancer; To find the effects of microflora and metabolites on target organs; To detect the mechanism of key flora and metabolite by in vitro and in vivo experiments; To construct models of gut microbiota and metabonomics by machine learning.
On the basis of previous studies, this study intends to explore the effect of BIFICO on liver function recovery of patients with hepatocellular carcinoma (HCC) after surgery, so as to provide a new method for accelerating liver function recovery of HCC patients during perioperative period. This project is an open, randomized, blank-controlled clinical study. Liver resection patients were randomly divided into two groups, one group received continuous administration of BIFICO during perioperative period, and the dosage was controlled according to the instructions. The other group was a blank control. Stool samples were collected at three time points (before medication, before and after surgery) in two groups. Statistical analysis was performed to compare the differences of postoperative liver function and preoperative and postoperative gut microbiota between the two groups. Through this study, the investigators aimed to verify the beneficial changes of intestinal microflora in HCC patients with BIFICO during perioperative period .
In this observational single-center cohort study, metagenomic Next-Generation Sequencing (mNGS) will be used to investigate the features and changes of gut microbiota in acute myeloid leukemia (AML) patients during the treatment of two different induction therapy regimens [standard intensive chemotherapy (7+3) or bcl-2 inhibitor-based targeted therapy].
The purpose of this study is to evaluate the effect of probiotics on the gut microbiota of infants born by cesarean section.
To explore and analyze the relationship between intestinal flora changes and the efficacy of individualized immunotherapy in patients with upper gastrointestinal cancer, and to find new biomarkers to predict the efficacy of immunotherapy, bringing new breakthroughs in tumor diagnosis and treatment.
Recent animal and human studies have found the relationship between the composition of the gut microbiota and hypertension, but some studies did not have a detailed evaluation of the diet content, which could be an important effect on gut microbiota. Moreover, most of these studies were finished in Western countries, in which the dietary patterns were significantly different from those in Chinese regions. This study intends to establish Taiwanese local data to explore the differences in the composition of gut microbiota among hypertensive patients and normotensive subjects.
To explore the changes in the composition and diversity of intestinal microbiota during 3-weeks of modified MAC diet and conventional diet in stage I or low-risk stage II colorectal cancer (CRC) patients after surgery. Additionally, the investigator analyze the association of gut microbiota and stool formation pattern or quality of life according to dietary pattern. Therefore, the investigator identify the beneficial or harmful microbiota composition and diversity adapting modified MAC diet that related to cancer recurrence, which provide supporting evidence for future prospective trial.
Acute myeloid leukemia (AML) patients are prone to blood stream infection (BSI) due to bone marrow suppression, oral and gastrointestinal mucositis, endovascular tubes, and the application of a large number of broad-spectrum antibiotics. The associated mortality rate is as high as 7.1 %-42%. The use of antibiotics within one hour after the first observation of hypotensive symptoms can guarantee a 79.9% survival rate. For every hour of delay, the patient's survival rate will drop by 7.6%. At present, the blood culture test cycle is long and the positive rate is low. Other infection-related indicators (PCT, CRP) or next-generation sequencing are not highly specific and easy to be misdiagnosed. X-ray, CT and other examinations only have a certain auxiliary value for the infected site. We need new diagnostic tools to accurately identify pathogens. Nano-seq is a next-generation sequencing technology for single-molecule, real-time sequencing and analysis. With ultra-long sequencing read length, it can quickly and accurately identify BSI pathogens types, and give appropriate drug sensitivity results based on drug resistance genes to meet the needs of 99.9% pathogen screening. At the same time, we hope to conduct a prospective evaluation to target high-risk groups of AML prone to BSI in the early stage. The intestine is the body's largest immune organ and the largest reservoir of microbial pathogens. The expansion of certain gut microbiota usually precedes BSI. If there is a correlation between the gut microbiota and MDR-BSI, the colonization and changes of the intestinal flora can be used to predict the risk of BSI in patients during treatment, and preventive measures such as early decolonization or biological intervention will reduce the risk of infection in the future. Combined with Nano-seq and various existing clinical pathogen detection technologies to reduce the occurrence and progress of clinical BSI.
The purpose of this study is to identify the variations in gut microbiota compositions between two subtypes of major depressive disorder.
