    Abstract Ethnopharmacological relevance: Heng-Gu-Gu-Shang-Yu-He-Ji (Osteoking, OK) is a well-known formula for fracture therapy. In clinic, OK is effective in treating fractures while alleviating osteoporosis (OP) symptoms. However, active components of OK and the associated molecular mechanisms remain not fully elucidated.
    Aim of the study: This study aims to systematically evaluate the anti-osteoporosis efficacy of OK and for the first time combine network pharmacology with high-throughput whole gene transcriptome sequencing to study its underlying mechanism.
    Materials and methods: In this study, the osteoporosis model was established by the castration of both ovaries. The level of serum bone turnover factor was detected by enzyme-linked immunosorbent assay. Micro-CT and HE staining were used to observe the changes of bone histopathology, and nano-indentation technique was used to detect the biomechanical properties of rat bone. The main active Chemical components of OK were identified using UPLC-DAD. Efficacy verification and mechanism exploration were conducted by network pharmacology, molecular docking, whole gene transcriptomics and in vivo experiments.
    Results: In our study, OK significantly improved bone microarchitecture and bone biomechanical parameters in OVX rats, reduced osteoclast indexes such as C-telopeptide of type I collage (CTX-I) and increased Osteoprotegerin (OPG)/Receptor activator of NF-κB ligand (RANKL) levels. Mechanistically, PI3K/AKT pathway was a common pathway for genome enrichment analysis (KEGG) of both network pharmacology and RNA-seq studies. G protein-β-like protein (GβL), Ribosomal-protein S6 kinase homolog 2 (S6K2), and Phosphoinositide 3-kinase (PI3K) appeared differentially expression in the PI3K-AKT signaling pathway. These results were also confirmed by qRT-PCR and immunohistochemistry.
    Conclusions: OK may be used to treat osteoporosis, at least partly by activating PI3K/AKT/mTORC1 signaling pathway.

    Abstract Two neutral polysaccharides (PSNP-1, 104.7 kDa; PSNP-2, 24.5 kDa) were isolated from the pulp of Pyrus sinkiangensis Yu. by using the combined techniques of ion-exchange and gel permeation chromatography. According to the IR, NMR spectra, monosaccharide composition, and methylation analyses, PSNP-1 was mainly composed of glucose and xylose residues, which form a typical xyloglucan. PSNP-2 contained an arabinan region composed of 1,5-linked Araf residues, a xyloglucan region that was mainly composed of t-, 1,2-linked Xylp, and 1,4-, 1,4,6-linked Glcp residues. PSNP-1 and PSNP-2 could stimulate the cell viability, NO release, and cytokine secretion (IL-6 and TNF-α) of RAW264.7 macrophages at the adosage of 250 μg/mL. It was suggested that PSNP-1 and PSNP-2 may increase macrophage-mediated immunostimulatory activity.

    Abstract Limonin, a compound of highly oxidized triterpenoids, has potential functions in preventing or slowing the occurrences of many diseases. In this study, five different bacterial strains were isolated and identified from Citrus maxima (Burm.) Merr. cv. Shatian Yu. Morphological characteristics and 16S rRNA gene sequencing identified them as Bacillus spp, in which two limonin-producing endophytes named P and P9 were discovered by high-performance liquid chromatography and mass spectrometry using an inorganic salt medium and two natural media; also the production was greater in natural medium 1 (4.377 and 0.299 mg/L, respectively) than in natural medium 2 (0.159 and 0.025 mg/L, respectively). The growth and fermentation characteristics of strain P were studied, and during the liquid cultivation of Bacillus sp. P, limonin began to accumulate at the eighth hour in the inorganic salt medium, peaked at the 16th hour, and then decreased sharply. Single-factor experiments revealed that the optimum fermentation conditions for limonin production included 14-H-old cells, 15% inoculum, and 3 g/L glucose.

    Abstract Active and prompt scale-up screening tests are essential to efficiently control the coronavirus disease 2019 (COVID-19) outbreak. The goal of this work was to identify shortcomings in the conventional screening system (CSS) implemented in the beginning of the outbreak. To overcome these shortcomings, we then introduced a novel, independently developed system called the Yeungnam University type drive-through (YU-Thru), and distributed it nationwide in Korea. This system is similar to the drive-throughs utilized by fast food restaurants. YU-Thru system has shortened the time taken to test a single person to 2-4 minutes, by completely eliminating the time required to clean and ventilate the specimen collection room. This time requirement was a major drawback of the CSS. YU-Thru system also reduced the risk of subjects and medical staff infecting one another by using a separate and closed examination system. On average, 50 to 60 tests were conducted per day when using the CSS, while now up to 350 tests per day are conducted with the YU-Thru system. We believe that the YU-Thru system has made an important contribution to the rapid detection of COVID-19 in Daegu, South Korea. Here, we will describe the YU-Thru system in detail so that other countries experiencing COVID-19 outbreaks can take advantage of this system.

    Abstract Ulcerative colitis (UC) is a chronic inflammatory disease afflicting the colon, showing a rising incidence worldwide. Chinese medicinal formulae have been identified to be effective for the clinical treatment of UC yet the underlying mechanism remains under-studied.We herein investigate the molecular mechanistic actions of Qing-Re-Xing-Yu (QRXY) decoction on the intestinal barrier dysfunction of UC.UC was induced in C57BL/6 mice by adding 3% dextran sulfate sodium (DSS) in the drinking water. Following this, the mice were administrated with QRXY decoction. Clinical symptoms were assessed, followed by determining the expression of NACHT, LRR, and PYD domains-containing protein 3 (NLRP3), inflammatory cytokines, Caco-2 cell viability, pyroptosis and permeability along with the lactate dehydrogenase (LDH) release in DSS-induced UC mice and NLRP3- or Gasdermin-D (GSDMD)-knockout Caco-2 cells. The GSDMD-overexpressing mouse model was constructed using the adeno-associated virus type 2 (AAV2) to examine its involvement in the role of QRXY in UC.QRXY decoction alleviated the DSS-induced intestinal mucosal damage in mice with UC. This effect of QRXY was associated with the downregulated activity of NLRP3 inflammasome. Mechanistic investigations showed that QRXY decoction impaired the DSS-induced Caco-2 cell pyroptosis and permeability in vitro by inhibiting the NLRP3-GSDMD signaling axis. Moreover, GSDMD overexpression attenuated the protective role of QRXY decoction in the intestinal barrier dysfunction.Our study reveals that QRXY decoction restores intestinal barrier function via a NLRP3-GSDMD feedback loop, suggesting that NLRP3-GSDMD signaling inhibitor may serve as a adjuvant agent for UC, providing novel insight into the clinical application of QRXY decoction with better efficiency and smaller side effect.

    Abstract The essential oil was isolated using the water steam distillation from the peel of Citrus maxima (Burm.) Merr. cv. Shatian Yu with a yield of 0.31% (w/w). The essential oil sample were analyzed by GC-MS and total sixty six components were identified. The major compounds were found to be identical namely D-limonene (86.4%) and nootkatone (2.11%). The essential oil displayed broad spectrum antibacterial activity against a panel of pathogenic bacteria and was most effective against Bacillus licheniformis. Thus, pummelo essential oil could be a potential antimicrobial agent.
