Autologous Probiotics in Patients With Defunctioning Ileostomy Following LAR for Rectal Cancer
Rectal cancer patients who received low anterior resection combined with ileostomy may effectively reduce the probability of anastomotic leakage after surgery. However, due to the long-term semi-abandoned state of the distal colon, the probability of bowel dysfunction after ileostomy closure is very high. The incidence of low anterior resection syndrome (LARS) exceeds 70%, which is twice that of those who did not receive a preventive stoma. The main reasons include postoperative anatomical structure alteration, nerve damage, pathological changes of the colorectal mucosa, and gut microbiota variation, etc. The application of probiotics can significantly improve the bowel function of these patients. In this study, in order to enhance the colonization effect of probiotics, autologous probiotics will be applied to treat patients with defunctioning ileostomy. The primary outcome is the occurrence of major LARS after 6 months of the treatment.

Therapeutic Strategies for Type 2 Diabetes Based on Lifestyle Changes: Plant-based Diet and Physical Exercise
The study evaluates the impact of a strict vegetarian diet combined with regular physical exercise and the use of probiotics on metabolic, inflammatory, and epigenetic parameters in patients with type 2 diabetes. It aims to determine the influence of these interventions on gut microbiota, glycemic control, body composition, insulin resistance, and quality of life.

Multimodal Image Technologies Investigate the Role and Mechanism of Probiotics in Improving RBD with Parkinson's Disease
Rapid eye movement sleep behavior disorder (RBD) is important non-movement feature, and also the important risk factor of Parkinson's disease (PD). In our previous work, we found that the movement features and RBD of PD patients improved after taking probiotics. The later was not reported before and the mechanism not clear. To investigate its role and mechanism, we plan to enroll patients of PD-RBD, idiopathic RBD, and healthy control, collect data of multimodal image technology before and after probiotic treatment,including resting state functional MRI,1H-MRS,123I-MIBG; analyze these data with clinical features, including UPDRS -III score, RBD-HK score , as well as the bacteria abundance and level of glutamate,GABA in blood and stool. Then, construct PD mouse model by fecal transplantation of PD patient, give or not give mouse probiotics treatment, and detect the level of glutamate, GABA, and so on, as well as α-synuclein of each brain area of each group, to explore the role and mechanism of probiotics in improving RBD and movement disorder of PD.
