RESUMEN
BACKGROUND: Diabetic gastroparesis (DGP) is a prevalent complication of diabetes that impairs people's quality of life and places a significant financial burden on them. The gastrointestinal symptoms of DGP patients can be improved by several Traditional Chinese Medicine (TCM) decoctions that have been shown to be effective in treating the disease. There are still many unanswered questions regarding the identification of appropriate therapeutic agents for the treatment of DGP in clinical practice. AIM: To analyze the efficacy of several TCM decoctions in the treatment of DGP using Bayesian network meta-analysis for reference. METHODS: PubMed, EMBASE, Cochrane Library, Web of Science, China National Kno-wledge Infrastructure, The China Biology Medicine DVD, Wanfang, and CQVIP were searched from inception to September 17, 2022, to collect randomized controlled trials (RCTs) about TCM decoctions for DGP. Clinical effects and symptom scores were the primary outcomes. Additionally, we assessed motilin (MOT), somatostatin (SS), gastrin (GAS), gastric emptying rate, gastric emptying time, and adverse drug events as secondary outcomes. RESULTS: A total of 67 eligible RCTs involving 4790 DGP patients and 7 TCM decoctions were included. The results of network meta-analysis (NMA) and surface under the cumulative ranking curve showed that with western medicine (WM) as a common control, the Banxia Xiexin Decoction (BXXD) + WM was most effective in clinical effects and enhancing early satiety scores; the Simo decoction (SMD) + WM was most effective in improving nausea and vomiting scores and anorexia scores, bloating scores; the Chaishao Liujunzi Decoction (CSLJD) was most effective in MOT, the Zhishi Xiaopi Decoction (ZSXPD) was most effective in SS and upgrading emptying rate; the Jianpi Xiaozhi Decoction was most effective in GAS; the CSLJD + WM was most effective in improving gastric emptying time. CONCLUSION: These NMA results suggest that the BXXD + WM and SMD + WM may be one of the potential optimal treatments. Due to various limitations, further large-sample, double-blind, multi-center randomized RCTs are needed.
RESUMEN
The family Flavobacteriaceae forms a major branch within the phylum Bacteroidetes. Whole-genome sequence-based analysis could significantly improve the accuracy of taxonomic assignments. In this study, phylogenomic analyses were carried out to revisit the taxonomic status of a clade of the family Flavobacteriaceae. Taking genome-based phylogeny as the primary guideline and average amino acid identity and phenotypic information as supplements, the following taxonomic proposals were put forward: Arenitalea lutea should be reclassified into the genus Algibacter; Algibacter aquaticus should be reclassified into the genus Flavivirga; Jejuia pallidilutea and Algibacter aestuarii should be reclassified into the genus Hyunsoonleella; Algibacter alginicilyticus should be reclassified into the novel genus Pseudalgibacter gen. nov. This study builds up a solid framework for taxonomic decisions of a clade of the family Flavobacteriaceae and will contribute to further insights into the evolution of this family.

Ganoderma applanatum is a fungus used for the prevention and treatment of a variety of disorders in China. In the present study, four new compounds, named shushe acids A-D (1-4), were isolated from the fruiting bodies of this species. Their structures were identified on the basis of spectroscopic methods. Compounds 1-4 are all natural product hybrids composed of derivatives of gallic acid, glycerol and succinic acid. None of the four compounds showed activity against the MCF-7 cell line.
