Exploring choices of early nutritional support for patients with sepsis based on changes in intestinal microecology

BACKGROUND Sepsis exacerbates intestinal microecological disorders leading to poor prognosis.Proper modalities of nutritional support can improve nutrition,immunity,and intestinal microecology.AIM To identify the optimal modality of early nutritional support for patients with sepsis from the perspective of intestinal microecology.METHODS Thirty patients with sepsis admitted to the intensive care unit of the General Hospital of Ningxia Medical University,China,between 2019 and 2021 with indications for nutritional support,were randomly assigned to one of three different modalities of nutritional support for a total of 5 d:Total enteral nutrition(TEN group),total parenteral nutrition(TPN group),and supplemental parenteral nutrition(SPN group).Blood and stool specimens were collected before and after nutritional support,and changes in gut microbiota,short-chain fatty acids(SCFAs),and immune and nutritional indicators were detected and compared among the three groups.RESULTS In comparison with before nutritional support,the three groups after nutritional support presented:(1)Differences in the gut bacteria(Enterococcus increased in the TEN group,Campylobacter decreased in the TPN group,and Dialister decreased in the SPN group;all P<0.05);(2)different trends in SCFAs(the TEN group showed improvement except for Caproic acid,the TPN group showed improvement only for acetic and propionic acid,and the SPN group showed a decreasing trend);(3)significant improvement of the nutritional and immunological indicators in the TEN and SPN groups,while only immunoglobulin G improved in the TPN group(all P<0.05);and(4)a significant correlation was found between the gut bacteria,SCFAs,and nutritional and immunological indicators(all P<0.05).CONCLUSION TEN is recommended as the preferred mode of early nutritional support in sepsis based on clinical nutritional and immunological indicators,as well as changes in intestinal microecology.

Research progress on the relationship between Paneth cellssusceptibility genes,intestinal microecology and inflammatory bowel disease

Inflammatory bowel disease(IBD)is a disorder of the immune system and intestinal microecosystem caused by environmental factors in genetically susceptible people.Paneth cells(PCs)play a central role in IBD pathogenesis,especially in Crohn's disease development,and their morphology,number and function are regulated by susceptibility genes.In the intestine,PCs participate in the formation of the stem cell microenvironment by secreting antibacterial particles and play a role in helping maintain the intestinal microecology and intestinal mucosal homeostasis.Moreover,PC proliferation and maturation depend on symbiotic flora in the intestine.This paper describes the interactions among susceptibility genes,PCs and intestinal microecology and their effects on IBD occurrence and development.

Rifaximin in the Treatment of Gastroesophageal Reflux Disease: A New Idea Based on the Relationship between Intestinal Microecology and Gastroesophageal Reflux Disease

Rifaximin in the Treatment of Gastroesophageal Reflux Disease (GERD) is a common clinical disorder, the most common symptom of which is a burning sensation behind the breastbone (heartburn) or reflux of stomach contents into the upper pharynx (acid reflux). The prevalence in China is increasing year by year, which can affect the quality of life of patients and also increase the economic burden on families and society. The pathogenesis of GERD is still unclear, and some studies suggest that intestinal microecology may be closely related to the development of GERD. Rifaximin is not readily absorbed orally and acts locally in the intestine, so it has mild adverse effects and good safety, and can be used to treat gastrointestinal diseases such as irritable bowel syndrome, traveler’s diarrhea, small intestinal bacterial overgrowth, diverticulosis, inflammatory bowel disease and hepatic encephalopathy. Therefore, this paper focuses on intestinal microecology as a possible pathogenesis of GERD and further explores the feasibility of rifaximin for the treatment of GERD.

Research progress on the correlation between gestational vaginal microecology and vaginal infectious diseases

The health status of the vaginal microenvironment, a complicated system, is an important indicator of female reproductive health. The vaginal flora is in a state of balance, and the microorganisms coexist and are interdependent to maintain the vaginal micro-ecological balance, which is a kind of dynamic balance influenced by endogenous and exogenous factors. Vaginal infections are traditionally treated by killing microbes in the vagina. Given the extensive study of the internal vaginal environment, people become gradually aware of the significance of maintaining the vaginal micro-ecological balance rather than blindly using antimicrobial agents. The balance in the vaginal internal environment is disrupted during the gestation period as the secretion of progesterone increases. The imbalanced vaginal micro-ecological environment may lead to vaginal infectious diseases. This paper provides a review of the relationship between the vaginal microecology and infectious diseases during gestation period.

A review of research progress on continuous cropping obstacles

Due to the increasing global population and limited land resources, continuous cropping has become common. However, after a few years of continuous cropping, obstacles often arise that cause soil degeneration, decreased crop yield and quality, and increased disease incidence, resulting in significant economic losses. It is essential to understand the causes and mitigation mechanisms of continuous cropping obstacles(CCOs) and then develop appropriate methods to overcome them. This review systematically summarizes the causes and mitigation measures of soil degradation in continuous cropping through a meta-analysis. It was concluded that not all continuous cropping systems are prone to CCOs. Therefore, it is necessary to grasp the principles governing the occurrence of diseases caused by soilborne pathogens in different cropping systems, consider plant–soil-organisms interactions as a system, scientifically regulate the physical and chemical properties of soils from a systems perspective, and then regulate the structure of microbial food webs in the soil to achieve a reduction in diseases caused by soilborne pathogens and increase crop yield ultimately. This review provides reference data and guidance for addressing this fundamental problem.

Changes of Intestinal Microecology in Patients with Primary Sjogren’s Syndrome after Therapy of Yangyin Yiqi Huoxue Recipe(养阴益气活血方)

Objective: To explore the change of intestinal microecology in patients with primary Sjogren’s syndrome(p SS) and correlation with disease activity, and also discuss the therapy effect of Yangyin Yiqi Huoxue Recipe(养阴益气活血方, YYHD). Methods: Sixteen p SS patients were enrolled in the present study, who received 3-month treatment of YYHR, 200 mL orally twice daily. Their pre-and post-test ESSDAI scores, erythrocyte sedimentation rate(ESR) and serum immunoglobulin G(IgG) levels were measured respectively. The 16 Sr DNA metagenomic sequencing was used to detect and analyze the abundance and diversity of intestinal bacteria flora and the proportion of bacteria at the levels of phylum, family, and genus, in comparision with those of 6 healthy subjects in the control group. Results: The abundance and diversity of intestinal bacteria flora in pSS patients were lower than those of healthy subjects(P<0.05). After the treatment with YYHD, patients’ ESSDAI score and levels of IgG and ESR have decreased significantly(P<0.05). At the phylum level, the proportions of Actinobacteria, Firmicutes, Fusobacteria and Proteobacteria have reduced sharply, while the proportions of Bacteroidetes, Teneriquetes and Candidate-division-TM7 have increased significantly by treatment(all P<0.05). At the classification level, such treatment has caused a significant decrease in the proportions of Bacteroidaceae, Ruminococcaceae, Veillonellaceae, and Enterobacteriacea(all P<0.05), but a significant increase in the proportion of Lachnospiraceae(P<0.05). At the genus level, the treatment has significantly decreased the proportions of Bifidobacterium, Bacteroides, Escherichia-Shigella, Faecalibacterium and Prevotella(all P<0.05), but significantly increased the proportion of Clostridia(P<0.05), close to the levels of healthy subjects(P>0.05). Conclusions: There exists an imbalance of intestinal microecology in p SS patients, which can be improved through the treatment with YYHD. Besides, such treatment can also improve the disease activity and adjust the diversity of intestinal bacteria flora, the composition and the abundance of intestinal flora.

Activated vascular endothelia regulate invasion of glioma cells through expression of fibronectin

Background Previous researches have indicated that glioma invasion may occur within a tumor-host microecology, and that fibronectin may be involved in glioma invasion as an important component of the extracellular matrix. However, how the interaction between tumor cells and vascular endothelial cells affects glioma invasion is poorly understood. The aim of this study was to investigate the effects of the interaction between tumor cells and vascular endothelial cells on glioma invasion, and the relationship of this interaction to fibronectin. Methods The localization of fibronectin in different brain astrocytoma tissues was determined by immunohistochemistry Then, vascular endothelial cells and glioma cells were co-cultured in a Transwell co-culturing system. Fibronectin expression was detected by reverse transcriptase-polymerase chain reaction, immunocytochemistry, and enzyme-linked immunosorbent assay. Additionally, the influence of the interaction between tumor cells and vascular endothelial cells on glioma cell invasion was determined by an in vitro rapid invasion test. Results In brain astrocytoma tissues, fibronectin was present on the endothelial cells, in the extracellular matrix. Fibronectin expression was greater in higher grade tumors than in lower grade tumors. The interaction of glioma cells and vascular endothelial cells in vitro induced fibronectin release from vascular endothelial cells, which in turn stimulated glioma cell migration. This effect was inhibited by fibronectin blocking antibody. Conclusion Glioma cells may induce vascular epithelial cells to express fibronectin, and in turn fibronectin could promote glioma cell invasion.

Intestinal Microecology:An Important Target for Chinese Medicine Treatment of Non-alcoholic Fatty Liver Disease

Non-alcoholic fatty liver disease(NAFLD)has become one of the most common chronic liver diseases worldwide,causing serious economic and medical burdens.Currently,Chinese medicine(CM)has become an important means in treating NAFLD in China.Intestinal microecology(IM)is an important part of the internal environment in the human body and is involved in the occurrence and development of NAFLD.In this paper,the authors systematically discuss the significance of IM in the pathogenesis of NAFLD and the current status of research on the CM treatment of NAFLD via IM regulation.In combination with our own research practice,we propose that IM is an important target for the treatment of NAFLD with CM and formulate plans for future research to target limitations existing in current studies.

Biochar-based Bacillus subtilis inoculant for enhancing plants disease prevention:microbiota response and root exudates regulation

Plants regulate root exudates to form the composition of rhizosphere microbial community and resist disease stress.Many studies advocate intervention with biochar(BC)and exogenous microbe to enhance this process and improve plant defenses.However,the mechanism by which BC mediates exogenous microorganisms to enhance root exudate-soil microbial defensive feedback remains unclear.Here,a BC-based Bacillus subtilis SL-44 inoculant(BC@SL)was prepared to investigate the defensive feedback mechanism for plants,which enhanced plant growth and defense more than BC or SL-44 alone.BC@SL not only strengthened the direct inhibition of Rhizoctonia solani Rs by solving the problem of reduced viability of a single SL-44 inoculant but also indirectly alleviated the Rs stress by strengthening plant defensive feedback,which was specifically manifested by the following:(1)increasing the root resistance enzyme activities(superoxide dismutase up to 3.5 FC);(2)increasing the abundance of beneficial microbe in soil(0.38-16.31%Bacillus);and(3)remodeling the composition of root exudates(palmitic acid 3.95-6.96%,stearic acid 3.56-5.93%,2,4 tert-butylphenol 1.23-2.62%,increasing citric acid 0.94-1.81%,and benzoic acid 0.97-2.13%).The mechanism reveals that BC@SL can enhance the positive regulatory effect between root exudates and microorganisms by optimizing their composition.Overall,BC@SL is a stable and efficient new solid exogenous soil auxiliary,and this study lays the foundation for the generalization and application of green pesticides.
