ABSTRACT
The impact of intestinal flora on human and animal health and diseases has attracted much attention both at home and abroad in recent years. The intestinal flora constitutes the intestinal microecosystem and plays an important role in physiological activities such as nutrition, metabolism, growth and development, barrier protection, and immunity. In this article, the relationship between intestinal dysbiosis and psychiatric diseases has been reviewed from two aspects:metagenomic characterization of intestinal microflora diversity in neurological diseases and validation of the relationship between intestinal flora and psychiatric diseases by fecal bacteria transplantation in germ-free mice. In addition, the microbial-gut-brain axis theory has been proposed in recent years, which links the nerve-endocrine-immune system to form a two-way signaling pathway. Intestinal flora plays an important role in regulating the central nervous system by promoting neurotransmitter release, endocrine, and immunity. The system plays an important role. Changes in intestinal flora mainly affect the host's nervous system through vagus nerve pathways, endocrine pathways, immune pathways, etc, thereby triggering or aggravating depression, autism, Alzheimer's disease, schizophrenia, Parkinson's disease, etc. This article reviews the relationships between host-related neurological abnormalities, intestinal flora imbalance and mental diseases, and discusses the research methods, research progress, and mechanism of the correlation between intestinal flora imbalance and mental diseases to research progress on microbe-gut-brain axis.
ABSTRACT
Intestinal microbes have an adjuvant therapeutic effect on neurological disorders (such as Parkinson's, depression, and Alzheimer's disease). It affects brain function and host behavior through the neural pathways, the immune pathways and the microbial metabolites, the so-called gut-brain axis. This article summarizes the recent advances in the role of the microbe-gut-brain axis in neurological disorders, in order to provide new ideas for the treatment of neurodegenerative diseases.

In recent years, with the gradual improvement of people's understanding of intestinal flora, exploring common complications after renal transplantation from the perspective of intestinal flora has become a research hotspot. Studies have demonstrated that the composition of the intestinal flora in renal transplant recipients has significant differences before and after surgery, and this difference is closely related to the occurrence and development of many complications after renal transplantation such as infection, rejection, diarrhea and so on, which could affect the prognosis of the recipients. This article reviewed the research progress on intestinal flora and renal transplantation in order to provide new treatment ideas and strategies for renal transplant recipients.
ABSTRACT
Objective:To explore the efficacy of Liuwei Nengxiao capsule combined with fecal bacteria transplantation on chronic functional constipation with spleen Qi deficiency. Method:A total of 129 patients with chronic functional constipation of spleen Qi deficiency treated in Affiliated Hospital of Shandong University of Traditional Chinese Medicine were randomly divided into three groups by the computer numerical table method： fecal bacteria transplantation group， Liuwei Nengxiao capsule group， and Liuwei Nengxiao capsule combined with fecal bacteria transplantation group， with 43 cases in each group. Fecal bacteria transplantation group was treated with fecal bacteria， Liuwei Nengxiao capsule group was treated with Liuwei Nengxiao capsule， and Liuwei Nengxiao capsule combined with fecal bacteria transplanted group was treated with Liuwei Nengxiao capsule combined with fecal bacteria. The efficacy of the 3 groups was compared. Result:After treatment， the frequency and amplitude of intestinal electricity increased significantly in three parts， with statistically significant differences from before treatment （P<0.05）. After treatment， the frequency and amplitude of the transverse colon， sigmoid colon， and descending colon of patients in Liuwei Nengxiao capsule combined with faecal transplantation group were higher than those in faecal transplantation group and Liuwei Nengxiao capsule group （P<0.05）. After treatment， substance P （SP） and motilin （MTL） of Liuwei Nengxiao capsule combined with faecal transplantation group were higher than those of faecal transplantation group and Liuwei Nengxiao capsule group， while nitric oxide （NO） and vasoactive intestinal peptide （VIP） were lower than those of faecal transplantation group and Liuwei Nengxiao capsule group （P<0.05）. The number of bifidobacteria and lactobacillus after treatment was higher in three groups than before treatment （P<0.05）. The numbers of yeast and enterobacteria were lower than before treatment （P<0.05）. After treatment， the number of bifidobacteria and lactobacillus in Liuwei Nengxiao capsule combined with faecal transplantation group was higher than that in faecal transplantation group and Liuwei Nengxiao capsule group， whereas the numbers of yeast， and enterobacteria were all lower than those in bacterial transplantation group and Liuwei Nengxiao capsule group （P<0.05）. After treatment， the BSFS scores of three groups were higher than before the treatment， while Wexner continence grading scale （Wexner） constipation score and patient assessment of constipation quality of life questionnaire （PAC-QOL） score were lower than before treatment （P<0.05）. Bristol stool form scale （BSFS） score of Liuwei Nengxiao capsule combined with fecal bacteria transplantation group was higher than that of fecal bacteria transplantation group and Liuwei Nengxiao capsule group. Wexner constipation score and PAC-QOL score were lower than those of fecal bacteria transplantation group and Liuwei Nengxiao capsule group （P<0.05）. Conclusion:Fecal bacteria transplantation combined with Liuwei Nengxiao capsule can effectively promote the recovery of intestinal electrical function， improve the intestinal flora balance， reduce the intestinal oxidative stress response， and promote the disappearance of patients' symptoms in the treatment of elderly chronic functional constipation， and thus is worth further promotion in clinic application.
ABSTRACT
Fecal bacteria transplantation is the "intermediate zone" between clinical trials and clinic.The vulnerability of patient and the "uncertainty" of technology result in the challenge of traditional informed consent pattern in voluntary,capacity and the requirement of information.In order to achieve the informed consent of clinical intervention of fecal bacteria transplantation,it should integrate doctor's professional standard with patient's subjective standard at the standard level;pay attention to inform the long-term risk,technical essence and operation process,relevant information about the donor and the fact that lack of big data at the content level;pay attention to the aesthetic requirements and dynamics in the informing mode.
