Recently, next generation sequencers(NGS)became prevalent and enable us possible to comprehensively analyze the entire human microbiome community structures including difficult-to-culture microbes. In this review, we introduce the NGS-based analytical methods of human microbiome, called "meta-16S analysis" and "metagenomic analysis", then show several fundamental data basing these analyses. Furthermore, we also introduce the importance of database improvement used for analysis and the DNA preparation method from human samples.

Department of Gastroenterology, The First Affiliated Hospital of Nanjing Medical University, Nanjing, China.
Background: Several clinical studies have demonstrated that Helicobacter pylori (Hp) infection may exacerbate the progression of Metabolic Dysfunction-Associated Steatotic Liver Disease (MASLD); however, the underlying mechanisms remain unclear. This study aims to investigate the characterization of the gastric microbiome and metabolome in relation to the progression of MASLD induced by Hp infection.
Methods: We established a high-fat diet (HFD) obese mouse model, both with and without Hp infection, to compare alterations in serum and liver metabolic phenotypes.

Objective: This study analyzed data from the US population to examine how oral microbiome diversity and diet quality individually and synergistically affect frailty.
Methods: This study included 6,283 participants aged 20 years or older from the 2009-2010 and 2011-2012 NHANES cycles. A frailty index (FI) consisting of 36 items was developed, with items related to nutritional status excluded.

This review article describes recent research advances in the relationship between spinal cord injury (SCI) and the gut microbiota and each other's inflammatory response. SCI is a serious neurological disease that directly damages physiological function. Recent studies have shown that SCI significantly affected the composition and function of the gut microbiota, and even caused intestinal inflammation.

Aim: To characterise periodontal and faecal microbiomes of individuals with periodontal health (PH) and diseases, and evaluate associations with periodontal, sociodemographic, anthropometric, nutritional and lifestyle factors.
Materials And Methods: Dental biofilm and faecal samples from individuals (n = 24/group) with PH, gingivitis (GG) and periodontitis (PE) were sequenced (16S rRNA). Anthropometric data and questionnaires on demographics, lifestyle, diet and intestinal habits were collected.

Background: In recent years, the problem of female alopecia has been increasing and has shown a trend toward youthfulness. However, there are fewer studies on young female alopecia in the existing literature.
Aim: We aimed to study the possible causes of hair loss in young Chinese females aged 18-35 with oily scalps.
