In gastroenterological practice,breath tests(BTs)are diagnostic tools used for indirect,non-invasive assessment of several pathophysiological metabolic processes,by monitoring the appearance in breath of a metabolite of a specific substrate.Labelled substrates originally employed radioactive carbon 14(^(14)C)and,more recently,the stable carbon 13 isotope(^(13)C)has been introduced to label specific substrates.The ingested^(13)C-substrate is metabolized,and exhaled^(13)CO_(2)is measured by mass spectrometry or infrared spectroscopy.Some^(13)C-BTs evaluate specific(microsomal,cytosolic,and mitochondrial)hepatic metabolic pathways and can be employed in liver diseases(i.***.simple liver steatosis,non-alcoholic steato-hepatitis,liver fibrosis,cirrhosis,hepatocellular carcinoma,drug and alcohol effects).Another field of clinical application for^(13)C-BTs is the assessment of gastric emptying kinetics in response to liquids(^(13)C-acetate)or solids(^(13)C-octanoic acid in egg yolk or in a pre-packed muffin or the^(13)C-Spirulina platensis given with a meal or a biscuit).Studies have shown that^(13)C-BTs,used for gastric emptying studies,yield results that are comparable to scintigraphy and can be useful in detecting either delayed-(gastroparesis)or accelerated gastric emptying or changes of gastric kinetics due to pharmacological effects.Thus,^(13)C-BTs represent an indirect,cost-effective and easy method of evaluating dynamic liver function and gastric kinetics in health and disease,and several other potential applications are being studied.

OBJECTIVE:To clarify the relationship between helicobacter pylori(Hp)infection,tongue manifestation and gastroscopic manifestation,and explore the mechanism of action of“oral-gastric microecology”in the occurrence and development of stomach-related diseases.MEDHODS:A total of 1100 patients were divided into Hp positive group and Hp negative group according to 13 C breath test results.The tongue manifestation materials from patients were collected to make tongue printing slides for morphological observation of exfoliative cells from tongue coating,and electronic gastroscopy was performed on the patients and the data was analyzed.RESULTS:Hp infection rate was about 45.95%;and the greasy coating was mostly observed in Hp positive group(63.14%,Pyellow coating>white coating>white greasy coating.The gastric mucosal roughness and mucosal hematoplastic plaques in the two groups were more common in the Hp positive group(P<0.05).There was a significant difference in the granular subgroup and in the rough mucosal group(P<0.05).CONCLUSIONS:Hp infection is more commonly observed in yellow greasy coating,and this can be used as a reference for Traditional Chinese Medicine in determining whether it is Hp infection or not.Mucosal granule roughness,hyperemia,and oral Hp showed association with Hp infection in the stomach and interacted with micro-ecological environment that is composed of the oral cavity.
