Abstract
BACKGROUND Emerging evidence indicates the role of gut microbiota in the development of cardiovascular diseases. Thus, gut microbiota is increasingly recognized as a potential therapeutic target of cardiovascular disease. However, the effects of gut microbiome-targeted therapies on cardiometabolic outcomes in children and adolescents remain unclear. METHODS We plan to perform a systematic search from PubMed, EMBASE, Cochrane Central Register of Controlled Trials, and Web of Science. Two authors will independently select the relevant studies and extract data according to a previously defined data extraction sheet. We will use the Stata 14.0 statistical software and RevMan V.5.3 software to conduct data analyses. RESULTS AND CONCLUSION The results of this study will be published in a peer-reviewed journal and provide more evidence for the application of gut microbiome-targeted therapies in children and adolescents for the intervention of cardiovascular risk factors in clinical practice.

Abstract
Objective This study was performed to investigate the role of probiotics ( Clostridium butyricum combined with Bifidobacterium infantis) in the treatment of minimal hepatic encephalopathy (MHE) in patients with hepatitis B virus (HBV)-induced liver cirrhosis. Methods Sixty-seven consecutive patients with HBV-induced cirrhosis without overt hepatic encephalopathy were screened using the number connection test and digit symbol test. The patients were randomized to receive probiotics (n = 30) or no probiotics (n = 37) for 3 months. At the end of the trial, changes in cognition, intestinal microbiota, venous ammonia, and intestinal mucosal barriers were analyzed using recommended systems biology techniques. Results The patients' cognition was significantly improved after probiotic treatment. The predominant bacteria ( Clostridium cluster I and Bifidobacterium) were significantly enriched in the probiotics-treated group, while Enterococcus and Enterobacteriaceae were significantly decreased. Probiotic treatment was also associated with an obvious reduction in venous ammonia. Additionally, the parameters of the intestinal mucosal barrier were obviously improved after probiotic treatment, which might have contributed to the improved cognition and the decreased ammonia levels. Conclusion Treatment with probiotics containing C. butyricum and B. infantis represents a new adjuvant therapy for the management of MHE in patients with HBV-induced cirrhosis.

Abstract
Present investigation is conducted to investigate the clinical efficacy of mesalazine in combination with the Bifid Triple Viable Capsules on the ulcerative colitis (UC) and the resultant effect on the inflammatory factors (TNF-α, IL-8 and IL-10) of UC patients. A total of 120 UC patients who were admitted to this hospital for treatment between May 2014 and February 2018 were enrolled in this study and divided randomly into the research group and control group, with 60 patients in each group. For patients in the two groups, they underwent medication via mesalazine, while those in the research group additionally received the medication by Bifid Triple Viable Capsules. Following treatment, we evaluated the clinical efficacy, as well as the disease activity index (DAI) of UC, score of clinical symptoms, changes in the inflammatory factors (TNF-α, IL-8 and IL-10) and the adverse reactions to drugs before and after treatment. The total effectiveness rate in the research group was 90.0%, significantly higher than 72.5% in the control group, and the difference had statistical significance (P < 0.05). Before treatment, we assessed the UCDAI and clinical symptoms, and found that there were no statistically significant differences in these indicators between two groups (P>0.05); however, after treatment, both of UCDAI and clinical symptoms scores were decreased evidently in two groups (P<0.05), while the decreases in the research group were more significant (P < 0.05). In addition, following treatment, the levels of TNF-α and IL-8 were all decreased in two groups, with an acute increase in IL-10 (all P<0.01), and the alterations in these indicators in the research group were much more significant than those in the control group (all P <0.05). For adverse reactions, the incidence rate in the research group was 6.67%, significantly lower than 33.33% in the control group (P <0.05). Mesalazine in combination with Bifid Triple Viable Capsules shows a magnificent protective effect on the mucosa of UC patients, and curb the UC-related inflammatory reactions effectively. Thus, it is a safe and reliable method that is worthy of being promoted in clinical practice.

Diet effects in gut microbiome and obesity.

Abstract
The 100 trillion microbes in human gut coevolve with the host and exert significant influences on human health. The gut microbial composition presents dynamic changes correlated with various factors including host genotypes, age, and external environment. Effective manipulation of the gut microbiota through diets (both long-term and short-term diet patterns), probiotics and/or prebiotics, and antibiotics has been proved being potential to prevent from metabolic disorders such as obesity in many studies. The dietary regulation exerts influences on microbial metabolism and host immune functions through several pathways, of which may include selectively bacterial fermentation of nutrients, lower intestinal barrier function, overexpression of genes associated with disorders, and disruptions to both innate and adaptive immunity. Discoveries in the interrelationship between diet, intestinal microbiome, and body immune system provide us novel perceptions to the specific action mechanisms and will promote the development of therapeutic approaches for obesity.
