GC-MS (gas chromatography-mass spectrometer)-based method for quantifying eleven types of short-chain fatty acids in intestinal contents and fecal samples

The invention belongs to the technical field of endogenous substance detection and discloses a GC-MS (gas chromatography-mass spectrometer)-based method for quantifying eleven types of short-chain fatty acids in intestinal contents and fecal samples. By adoption of a hydrochloric acid solution prepared from saturated salt water for acidification, high-stability ethyl acetate for extraction and N-tert-butyldimethylsilyl-N-methyl trifluoroacetamide MTBSTFA for derivatization, the eleven short-chain fatty acids in mouse intestinal contents and fecal samples are quantified by a gas chromatography-mass spectrometer. The method is high in accuracy and precision and low in detection limit, can be used for quantitative detection of eleven types of short-chain fatty acids and can meet detection requirements on determination of major short-chain fatty acids in the mouse intestinal contents and the fecal samples. Moreover, the method is conducive to analysis and comparison of metabolic disposition laws of the short-chain fatty acids under normal and enteritis conditions and observation whether changes of the short-chain fatty acids can represent dynamic conditions of enteritis or not, thereby providing significant bases for potential biomarkers under the enteritis condition.

Medical equipment and application thereof

The invention relates to the field of medical equipment and application thereof, and provides a duodenum internal covering film. The duodenum internal covering film is made of biocompatible biodegradable or non-biodegradable material or / and hydrophobic material and is mainly composed of an elastic ampullar portion and a tubular portion. The ampullar portion comprises a biocompatible bionic micro array adhesion piece which can achieve strong adhesion in the force application direction, does not stab intestine tissues and is capable of achieving detachment and recovery easily. The adhesion piece is good in stability, strong in adaptability to material and shapes, good in self-cleaning performance, free of damage and pollution to the intestine tissues, and capable of achieving repeated adhesion and detachment and supporting other components mutually in functions. When intestinal tract contents move, the internal covering film can not be detached due to the fact that subvertical pulling force does not exist. When the duodenum bulb is expanded and inflated, the internal covering film can not be detached due to the fact that the internal covering film does not have opposite and subvertical pulling force, and in the process of recovery, the internal covering film can be detached and recovered easily through force applied in a subvertical mode. The duodenum internal covering film can be manufactured into the medical equipment which does not damage the intestine tissues and can prevent and cure fat and diabetes.

Method for rapid determination of content of short-chain fatty acids in intestinal tract or excrement

A method for rapid determination of content of short-chain fatty acids in intestinal tract or excrement comprises the following steps: (1) carrying out homogeneous dilution by using intestinal contents or distilled water for excrement at the ratio of 1:9-1:14, uniformly mixing, centrifuging a mixture for 15-20 min, and taking 0.5-1 ml of a supernatant; (2) carrying out chromatographic analysis through Agilent 6890 N gas chromatography and an HP-INNOWAX chromatographic column; gas phase analysis conditions: an FID detector is used and carrier gas is N2; N2 flow velocity is 19.0ml/min, and split ratio is 1:10; air velocity is 300 ml/min, and H2 flow velocity is 30 ml/min; detector temperature is 240 DEG C, and injection port temperature is 240 DEG C; temperature programming: after maintaining 100 DEG C for 0.5 min, heating to 150 DEG C at the temperature rising speed of 4 DEG C/min, and measuring for 13 min; inlet sample quantity is 0.2-0.5 microliter, 3 times of separate repeated measurements are carried out for each sample for each time, and data analysis is carried out by HP Chem workstation software. Only after homogenizing a sample in distilled water and centrifuging the sample, a supernatant is taken to directly carry out gas phase sample-introduction and analysis, and measurement time can be reduced remarkably. In addition, the method is simple, rapid and accurate.
