Many diseases with origin in human gut are of unknown causes, so only symptoms are treated. Endoscopic devices leave about 15′ of gut unexplored other than by autopsy. Thus, a substance and microbe simultaneous sample collecting, testing, evaluation, and characterization system has been invented that will provide data for evaluating functions, macro, and micro processes taking place along entire length of the human digestive and intestinal tract from mouth to anus. The entire digestive process including biochemical reactions and microbe roles, and consequences, as pertain to diseases and illnesses can be ascertained through applications of the system, which includes protocols, for collection and preservation of digestion products for external analysis, measurements of many in vivo conditions, and internally processing data and making decisions based upon said processed data, including administration of medications. The system serves clinical diagnostic, treatment and research purposes, and is a dream tool for gastroenterologists.

The invention discloses a method for preparing microcapsules by embedding lutein in starch. In this method, a certain concentration of starch milk is firstly heated and expanded for 0.5-2 hours to form expanded starch, and then the solvent containing lutein is added dropwise while keeping warm and stirred, reacted for 0.5-4 hours, cooled, and recrystallized at 4-25°C for 4-2 hours. After 12 hours, centrifuge, wash and dry to obtain lutein microcapsules. The content of lutein in the obtained lutein microcapsules is 2.40-2.54mg / g, and the lutein retention rate can reach 72.1% after the three-week storage stability test, and the release rate can reach 87.2% under the condition of human intestinal fluid, reaching The purpose of targeted intestinal slow-release is more conducive to the absorption and utilization of lutein by the human body. The method is simple, effective and energy-saving for embedding lutein, reduces production cost, enhances the protection of lutein during storage and transportation, has strong stability and good slow-release effect in human intestinal tract.

This special gut microbe and chemical substance sampling technology, utilizing swallowable capsules, is for purpose of determining roles gut contents play in some 52 of most costly, in lives and dollars, of diseases with their known origin in the human gut. Gut microbes and substances are collected, analyzed, medicinal substances and objects deployed, and special provisions for attracting, capturing and preserving certain strains of microbes, and means for perturbing the gut environment and immune system are all intended to research, discover, and ultimately find both the causes and cures for the most devastating human diseases, and in the process, create gut microbiome profiles.

An in vitro microfluidic intestine on-chip is described herein that mimics the structure and at least one function of specific areas of the gastrointestinal system in vivo. In particular, a multicellular, layered, microfluidic intestinal cell culture, which is some embodiments is derived from patient's enteroids-derived cells, is described comprising L cells, allowing for interactions between L cells and gastrointestinal epithelial cells, endothelial cells and immune cells. This in vitro microfluidic system can be used for modeling inflammatory gastrointestinal autoimmune tissue, e.g., diabetes, obesity, intestinal insufficiency and other inflammatory gastrointestinal disorders. These multicellular-layered microfluidic intestine on-chips further allow for comparisons between types of gastrointestinal tissues, e.g., small intestinal duodenum, small intestinal jejunum, small intestinal ileum, large intestinal colon, etc., and between disease states of gastrointestinal tissue, i.e. healthy, pre-disease and diseased areas. Additionally, these microfluidic gut-on-chips allow identification of cells and cellular derived factors driving disease states and drug testing for reducing inflammation.
