Chronic hepatitis B (CHB) is a global epidemic disease caused by hepatitis B virus that can lead to hepatic failure, even liver cirrhosis and hepatocellular carcinoma. The occurrence and development of CHB are closely related to the changes in the gut microbiota communities. To explore the relationship between the structure of gut microbiota and liver biochemical indicators, 14 CHB patients (the CHB group) and 11 healthy people (the CN group) were randomly enrolled in this study. Our results demonstrate that CHB caused changes in the gut microbiota communities and biochemical indicators, such as alanine transaminase, total bilirubin and gamma glutamyl transferase. Furthermore, CHB induced imbalance of the gut microbiota. Prevotella, Blautia, Ruminococcus, Eubacterium eligens group, Bacteroides uniformis and Ruminococcus sp. 5_1_39BFAA were associated with the critical biochemical indicators and liver injury, suggesting a new approach to CHB treatment.

Intestinal flora and its metabolites are closely related to the progression of type 2 diabetes mellitus(T2DM). Eubacterium is one of the dominant intestinal flora, and its metabolites short-chain fatty acids (SCFAs) play a leading role in regulating intestinal metabolic balance. It has been reported that SCFAs can regulate the secretion of glucagon-like peptide-1, improve the function of pancreatic β cells, participate in bile acids metabolism and regulate the production of inflammatory factors in T2DM. Based on the above research background, this article mainly reviews the relationship between Eubacterium and its metabolite SCFAs and T2DM and its regulatory mechanism.

In a general way, anaerobic isolation is troublesome and needs competent personnel and fittings. In addition, bacterial isolation from the prostate is disappointing because of difficulty in interpretation of the results. In this experiment, we tried the best way to isolate anaerobes from the prostate in terms of processing of the specimens such as catching, transportation, etc. We performed this antegrade experiment for 12 months in 1992 and got the results from 43 patients with chronic prostatitis syndrome as follows. l. Age distribution was in broad range between 20 and 54 showing peak incidence in 31-40 years(49% ) and the next in 20-30 years( 30%). 2. Subjective symptoms and signs consisted of perineal discomfort, suprapubic discomfort, frequency, urethral discomfort, dysuria, morning drop, testicular discomfort, and hemospermia 3. Majority of the cases( 36 cases. 83.7% ) were normal in the microscopy of VB1 EPS of 31 cases(72%) showed WBC more than 10/HPF. VB3 of 23 cases(53.5% ) showed than l0/HPF 4. A total of 40 cases showed aerobes in EPS and/or VB3 by culture. However, only 8 cases showed aerobes in EPS and/or VB, exclusive of 32 cases in which aerobes also appeared in VB1. 5. Anaerobic bacteria were cultured only from EPS for a total of 8 cases. There were 2 cases with Bacteroides species, 2 cases with Prevotella bivia, 2 cases with Peptostreptococcus anaerobrus,2 cases with Actinomyces meyeri, 1 case with Eubacterium lentum and 1 case with Eubacterium limosum.

BACKGROUND: Factors affecting oral function include tooth number, oral muscle strength, and oral diseases. This study aimed to investigate the relationship among oral environment, muscle, and microbiology. METHODS: Fifty-six elderly individuals in a day care center were included in the study. The survey regarding tongue and lip muscle strength and oral microorganisms was conducted from November to December 2018. RESULTS: Tongue and lip muscle strength were greater in men than women (p>0.05). Tongue muscle strength was greater in the ≤80-year-old group (34.94±9.85) than the ≥90-year-old group (25.57±7.54) (p<0.05). Tongue muscle strength and lip muscle strength were greater in the ≥15 functional teeth group (34.08±9.31 and 9.25±1.63, respectively) than in the <15 functional teeth group (28.08±7.53 and 7.76±1.51, respectively) (p<0.05). Age was significantly correlated with functional tooth number, denture use, and tongue muscle strength. The number of functional teeth was positively correlated with tongue muscle strength, lip muscle strength, and oral microorganisms. Denture use was negatively correlated with tongue and lip muscle strength. Tongue muscle strength was significantly correlated with lip muscle strength. The number of Eubacterium nodatum was higher in men than women. The number of Parvimonas micra and Enterococcus faecalis was higher in the groups with ≥15 functional teeth, denture use, and greater tongue and lip muscle strength. The number of Lactobacillus casei was higher in the group that uses dentures and with greater tongue strength. CONCLUSION: Oral microbiology is more important in oral environment and management than oral muscle function. The correlation between oral muscle and oral microorganism requires further study. Therefore, oral care training should be conducted to improve the oral care practice of elderly individuals, maintain oral health through oral care, and prevent the decrease in saliva secretion by aging.

OBJECTIVETo investigate the changes in fecal flora and its correlation with the occurrence and progression of inflammatory bowel disease (IBD).

METHODSWe collected fresh fecal specimens from 167 IBD patients (including 113 with ulcerative colitis and 54 with Crohn's disease) and 54 healthy volunteers. The fecal flora was analyzed by gradient dilution method and the data of inflammatory markers including WBC, PLT, CRP and ESR were collected to assess the association between the fecal flora and the inflammatory markers.

RESULTSThe species Enterrococcus (6.60∓0.23, P<0.01), Saccharomyces (2.22∓0.27, P<0.05), Bacteriodes (5.57∓0.28, P<0.001), Bifidobacterium (5.08∓0.30, P<0.01), Peptococcus (6.22∓0.25, P<0.001), Lactobacillus (6.00∓0.26, P<0.001), and Clostridium (3.57∓0.30, P<0.05) all increased significantly, while Eubacterium (1.56∓0.24, P<0.01) reduced markedly in patients with ulcerative colitis compared with those in the control subjects. Enterrococcus (6.93∓0.28, P<0.01), Saccharomyces (2.73∓0.37, P<0.01), Bacteriodes (4.32∓0.52, P<0.05), Bifidobacterium (4.88∓0.42, P<0.05), Peptococcus (6.19∓0.32, P<0.01) and Lactobacillus (4.73∓0.47, P<0.001) all increased significantly and Eubacterium (1.01∓0.29, P<0.01) and Clostridium (0.87∓0.31, P<0.01) decreased in patients with Crohn's disease. The positivity rates of bacterial culture were consistent with the results of quantitative analysis of the fecal flora. The changes in fecal flora did not show a significant correlation with these inflammatory markers.

CONCLUSIONIBD patients have fecal flora imbalance compared with the healthy controls, and this imbalance may contribute to the occurrence and progression of IBD. The decline of Eubacterium contributes to the occurrence and development of IBD.
