Background/Aims: Systemic Inflammation (SI) is considered a key mechanism in disease progression and development of complications in decompensated liver cirrhosis. SI is mainly driven by portal hypertension and bacterial translocation. Transjugular intrahepatic portosystemic shunt (TIPS) insertion represents an effective treatment for portal hypertension. This study aims to investigate the impact of TIPS insertion on SI and bacterial translocation. Methods: We prospectively included 59 cirrhotic patients undergoing TIPS insertion. Blood samples were collected at TIPS insertion and follow-up (FU) 1, 3, 6, and 12 months thereafter. At all time points, we performed a comprehensive analysis of SI including 43 soluble inflammatory markers (SIMs), and surrogates of bacterial translocation (sCD14, sCD163). To investigate long-term kinetics of SI, C-reactive protein (CRP) and white blood cells (WBC) were retrospectively analyzed in a cohort of 177 patients up to 3 years after TIPS insertion. Results: At TIPS insertion, 30/43 SIMs, sCD14, and sCD163 measured significantly higher in cirrhotic patients compared to healthy controls. By FU6 25 SIMs and sCD14 measured at significantly lower levels compared to baseline. Interestingly, in patients with TIPS indication of refractory ascites, IL-6 decreased to levels documented in earlier stages of cirrhosis. In long-term follow-up, CRP levels significantly decreased after TIPS insertion, which translated into lower mortality in Cox regression analysis (HR 0.968, p=0.042). Notably, patients with residual ascites post-TIPS showed significantly higher CRP and IL-6 levels across all follow-ups compared to patients with resolved ascites. Conclusions Decreasing portal hypertension via TIPS insertion leads to a significant attenuation of SI and bacterial translocation over time.

Global public health faces substantial challenges from malignant tumors and infectious diseases. Vaccination provides an approach for treating and preventing these diseases. Oral vaccinations are particularly advantageous in disease treatment and prevention due to their non-invasive nature, high patient compliance, convenience, cost-effectiveness, and capacity to stimulate comprehensive and adaptive immune responses. However, the overwhelming majority of oral vaccines remain in experimental development, struggling with clinical and commercial translation due to their suboptimal efficacy. Thus, enhancing scientists' understanding of the interaction between vaccines and gastrointestinal immune system, creating antigen delivery systems suitable for the gut mucosal environment, developing more potent antigenic epitopes, and using personalized combination therapies are critical for advancing the next generation of oral vaccines. This article explores the fundamental principles and applications of current oral anti-tumor and anti-infective vaccines and discusses considerations necessary for designing future oral vaccines.

Aging involves the accumulation of various forms of molecular and cellular damage over time. Key features of aging, such as mitochondrial dysfunction, dysbiosis, and oxidative stress, are closely linked and largely driven by inflammation. This study examines the role of succinate, a key metabolite produced and utilized by cells of both host and microbes, and its receptor, succinate receptor 1 (SUCNR1), in age-related oral dysbiosis and inflammation. We examined young and aged wild-type (WT) and SUCNR1 knockout (KO) mice for this analysis. Our findings revealed significant aging-associated alveolar bone loss and succinate elevation in aged WT mice, along with notable changes in the oral microbiome. Conversely, aged KO mice showed reduced bone loss, lower succinate levels, less inflammation, and better-maintained microbial function. These results suggest that SUCNR1 is crucial in influencing aging-related succinate elevation, oral dysbiosis, and inflammation. Analysis of gene families and pathways in the oral microbiome demonstrated distinct aging-related changes between WT and KO mice, with the functional potential being preserved in the KO-aged group. This study underscores the importance of succinate elevation and signaling through SUCNR1 in regulating inflammation, alveolar bone loss, and shifts in the oral microbiome, offering potential targets for therapeutic interventions in age-related oral health issues.

OBJECTIVE: This cross-sectional study assessed the methodological quality of systematic reviews (SRs) of Chinese herbal medicine (CHM) published in Chinese between Jan 2021 and Sep 2022. METHODS: Chinese language CHM SRs were identified through literature searches across 3 international and 4 Chinese databases. Methodological quality was appraised using A MeaSurement Tool to Assess systematic Reviews 2. Logistic regressions were used to explore associations between bibliographical characteristics and quality. RESULTS: Analyses of methodological quality found that among the 213 sampled SRs, 69.5% were of critically low quality, 30.5% were of low quality, and none achieved high or moderate quality. Common shortcomings included the failure to identify the studies excluded from the analysis, failure to disclose funding sources, and limited evaluation of the potential impact of bias on conclusions. Logistic regressions revealed that SRs led by corresponding authors affiliated with universities or academic institutions tended to be of lower quality than SRs led by authors affiliated with hospitals or clinical facilities. CONCLUSION Recent Chinese language CHM SRs exhibited limited methodological quality, making them unlikely to support the development of clinical practice guidelines. Urgent initiatives are needed to enhance training for researchers, peer-reviewers and editors involved in the preparation and publication of SRs. Adoption of Preferred Reporting Items for Systematic Reviews and Meta-Analyses reporting guidelines in Chinese language journals is crucial to improve the relevance of SRs for Chinese medicine development. Addressing deficiencies in methodology and reporting is essential for promoting evidence-based practices and informed clinical decisions in Chinese medicine.
