ObjectiveTo investigate the potential mechanisms of Zingiberis Rhizoma in treating inflammatory bowel disease (IBD) by integrating network pharmacology with in vitro and in vivo experiments. MethodsTraditional Chinese Medicine Systems Pharmacology Database And Analysis Platform (TCMSP), Traditional Chinese Medicine Integrated Database (TCMID) Database were used to obtain the active component targets of Zingiberis Rhizoma. GeneCards was used to obtain the IBD targets. DAVID was used to perform Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analyses on core targets. Cytoscape 3.10.2 was used to establish the "active component-disease target-signaling pathway" interaction network. Mice were randomly assigned to control, model, and Zingiberis Rhizoma (400 mg·kg-1) groups. An IBD model was induced via dextran sulfate sodium (DSS). The colonic tissue was collected post-treatment to assess histology, expression of Ly6C+ monocytes/macrophages, and mRNA levels of Toll-like receptor 4 (TLR4), and inflammatory cytokines. The effect of Zingiberis Rhizoma aqueous extract on RAW264.7 cell viability was evaluated. Furthermore, the effects of the extract at 100, 10, and 1 mg·L-1 on LPS-induced differentiation of RAW264.7 cells into Ly6Chi monocytes/macrophages, mRNA levels of TLR4 and inflammatory cytokines, and protein levels of factors in the TLR4/mitogen-activated protein kinase (MAPK) signaling pathway. ResultsA total of 241 targets were identified for Zingiberis Rhizoma and 6 787 for IBD, with 122 shared targets among Zingiberis Rhizoma, ulcerative colitis (UC), and Crohn's disease (CD). The enrichment analyses yielded 297 GO terms and 88 KEGG pathways. Associations were noted between Zingiberis Rhizoma's active component targets and IBD targets. In vivo experiments: Compared with the control group, the model group showed decreased body weight and disease activity index (DAI)(P<0.01), shortened colon length, damaged mucosal epithelium with inflammatory cell infiltration, raised pathological scores (P<0.05), increased Ly6Chi and Ly6Clo monocytes/macrophages (P<0.05), and up-regulated mRNA levels of TLR4, TNF-α, IL-1β, and IL-6 (P<0.05) and protein levels of TLR4, phosphorylated extracellular signal-regulated protein kinase 1/2 (p-ERK1/2), and phosphorylated p38 MAPK (p-p38 MAPK) (P<0.05). Zingiberis Rhizoma intervention reversed these changes and reduced Ly6Chi monocytes/macrophages (P<0.01). In vitro experiments: compared with the control, LPS increased the proportion and number of Ly6Chi monocytes/macrophages and mRNA levels of TLR4, TNF-α, IL-1β, and IL-6 (P<0.01) and enhanced the expression of TLR4, p-ERK1/2, and p-p38 MAPK (P<0.05). Zingiberis Rhizoma reduced Ly6Chi monocytes/macrophages (P<0.05), down-regulated the mRNA levels of inflammatory cytokines (P<0.05), and suppressed the TLR4/MAPK pathway (P<0.05). ConclusionZingiberis Rhizoma alleviates IBD by suppressing the TLR4/ERK/p38 MAPK signaling pathway and reducing inflammatory cytokine levels in Ly6Chi monocytes/macrophages.

ObjectiveTo clarify the repair effect of Mume Fructus on the intestinal mucosal epithelial barrier in the mouse model of inflammatory bowel disease (IBD) and explore the repair mechanism. MethodsThirty-six male C57BL/6 mice were randomly assigned into six groups: normal, model, low-, medium-, and high-dose (200, 400, and 800 mg·kg-1) Mume Fructus, and sulfasalazine (300 mg·kg-1). Except the normal group, the rest groups had free access to 2% dextran sulfate sodium (DSS) solution for seven days to establish the IBD model, followed by a seven-day drug intervention. The body weight change and disease activity index (DAI) were recorded. After the last administration, spleen and colon tissue samples were collected to analyze the differences in colon length and spleen index. Hematoxylin-eosin staining was used to observe the morphology of the colon tissue. The level of diamine oxidase (DAO) in the serum was measured by the DAO assay kit. Immunohistochemistry was employed to determine the expression of tight junction proteins such as Claudin-1, Occludin, and zonula occludens-1 (ZO-1) in the colon tissue. Real-time PCR was performed to measure the mRNA levels of tumor necrosis factor-α (TNF-α) and interleukin-1β (IL-1β) in the colon tissue. Finally, Western blot was employed to determine the protein levels of mitogen-activated protein kinase kinase (MEK), extracellular signal-regulated kinase (ERK), phosphorylated (p)-MEK, and phosphorylated ERK in the colon tissue. ResultsCompared with the normal group, the model group exhibited decreases in body weight and colon length (P<0.01), increases in DAI, spleen index, and serum DAO level (P<0.01), damaged colonic epithelium and goblet cells, and obvious infiltration of inflammatory cells. In addition, the model group exhibited higher positive expression of Claudin-1, Occludin, and ZO-1 (P<0.01), higher mRNA levels of TNF-α and IL-1β (P<0.01), and higher protein levels of p-MEK and p-ERK (P<0.05, P<0.01) than the normal group. However, sulfasalazine and three doses of Mume Fructus markedly decreased the body weight and DAI (P<0.05), recovered the colon length and spleen index, alleviated colon tissue damage, lowered the level of DAO in the serum (P<0.01), and down-regulated the mRNA levels of TNF-α and IL-1β (P<0.01) and the protein levels of p-MEK and p-ERK (P<0.05). Sulfasalazine and low- and medium-dose Mume Fructus increased the positive expression of Occludin, Claudin-1, and ZO-1 (P<0.05, P<0.01). Furthermore, high-dose Mume Fructus elevated the protein expression of Occludin (P<0.05). ConclusionMume Fructus can restore the expression of intestinal epithelial tight junction proteins by inhibiting the phosphorylation of proteins in the MEK/ERK signaling pathway and down-regulating the levels of TNF-α and IL-1β, thus repairing the intestinal mucosal barrier in the mouse model of IBD.

ObjectiveTo investigate the modulating effect of modified Wumeiwan (MWMW) on the ulcerative colitis (UC)-associated intestinal helper T cell 17 (Th17)/regulatory T cell (Treg) balance and intestinal flora by using a human flora-associated model of UC patients with dampness-heat obstruction syndrome, thus providing a new idea for the UC-related research and therapeutic strategies. MethodsThe 24 male C57BL/6J mice were randomized into normal control, model, and MWMW groups (n=8). Model and MWMW groups were first treated with an antibiotic cocktail (vancomycin, 0.1 g·kg-1; neomycin sulfate, 0.2 g·kg-1; ampicillin, 0.2 g·kg-1; metronidazole, 0.2 g·kg-1) for 21 days. At the end of antibiotic treatment, the gavage of fecal microbiota suspension from UC patients with dampness-heat obstruction syndrome was started at a dose of 0.2 mL·d-1 for 19 consecutive days, by which a human flora-associated model of UC was obtained. The MWMW group was administrated daily with MWMW liquid (12.5 g·kg-1), while the normal control and model groups were administrated by gavage with an equal amount of sterile water for 7 consecutive days. The symptoms of dampness-heat obstruction were observed. The colon length and spleen index were measured and calculated, and the proportions of Th17 and Treg cells were detected by flow assay. The intestinal flora was analyzed by 16S rRNA high-throughput sequencing. ResultsCompared with the normal control group, the model group showed shortened colon (P<0.05) and increased spleen index (P<0.01). Compared with the model group, the MWMW group showed prolonged colon (P<0.01) and decreased spleen index (P<0.05). After the intervention of MWMW, the Th17 proportion and Th17/Treg ratio in the colon decreased (P<0.01), and the proportion of Treg cells increased (P<0.05). The number of species and alpha and beta diversity of intestinal flora in mice were regulated by MWMW (P<0.05). In terms of intestinal flora composition, MWMW increased the relative abundance of several phyla (Firmicutes, Proteobacteria, Fusobacteriota, Actinobacteriota, and Gemmatimonadota), the genus Bacteroides, and two species (Bacteroides thetaiotaomicron and B. fragilis) in model mice. Moreover, Spearman's correlation analysis showed that the relative abundance of B. thetaiotaomicron and B. fragilis were negatively correlated with the Th17 level (P<0.05). In addition, the above changes in intestinal flora caused the changes in microbial genes involved in 14 pathways, such as glycolysis, amino acid degradation, inorganic nutrient metabolism, biosynthesis of pyrimidine deoxyribonucleotides, antibiotic resistance, and degradation of polysaccharides. ConclusionsThe human flora-associated model successfully simulated the changes (marked by a decrease in the abundance of Bacteroides) of intestinal flora in UC patients with dampness-heat obstruction syndrome. MWMW can enrich the abundance of beneficial bacteria such as B. thetaiotaomicron and B. fragilis and promote the synergistic intestinal immune modulation with the metabolic functions centered on glycolysis, amino acid metabolism, and nucleotide synthesis through bacterial polysaccharide utilization sites to reduce the Th17/Treg ratio, thereby exerting a protective effect on UC.

Acute liver failure (ALF) is lack of broadly approved therapeutic strategy except liver transplantation. As a glycogen metabolic intermediate, UDP-glucose (UDP-G) has been considered to accelerate liver repairment. Nevertheless, the role of UDP-G and its receptor P2Y purinoceptor 14 (P2Y14R) in ALF remains unknown. The present study aims to investigate the role and underlying mechanisms of UDP-G/P2Y14R axis in ALF. In this study, hepatic P2Y14R is significantly increased in TAA-induced and partial hepatectomy-induced ALF, while knockout of whole-body P2Y14R aggravates liver failure, manifested by inhibiting β-Catenin-mediated liver regeneration. Consistently, P2Y14R deficiency exhibits impaired liver regeneration in mice suffer partial hepatectomy. Importantly, only hepatocellular specific deletion of P2Y14R (P2Y14R flox/flox Alb cre/+ ) mice shows a similar phenomenon, rather than stellate cell specific deletion of P2Y14R (P2Y14R flox/flox Lrat cre/+ ) mice. Mechanistically, P2Y14R induction regulates methylation of Dact-2 through CREB/DNMT3b signals in hepatocytes, subsequently inhibiting the expression of Dact-2 which is a stabilizer of β-Catenin degradation complex, leading to the activation of β-Catenin -mediated liver regeneration. Interestingly, the administration of exogenous UDP-G can accelerate liver regeneration and liver function recovery after partial hepatectomy in hepatocellular carcinoma mice. Together, the findings propose an unrecognized role of P2Y14R in ALF and provide an effective adjuvant strategy for treatment of ALF.

Objective:To study the regional distribution, temporal trend, and health inequity of burn incidence in the world from 1990 to 2019.Methods:The data related to burns worldwide from 1990 to 2019 were collected from the database of Global Burden of Disease (GBD). Based on the number of burn cases and age-standardized incidence rates, the incidence of burn was observed by age, region, socio-demographic index (SDI) area (divided into 5 categories of SDI areas: high, medium-high, medium, medium-low and low, the higher the area, the higher the degree of social development) and country, all of which were expressed as estimated values. Joinpoint regression analysis of the age-standardized incidence of burns from 1990 to 2019 was performed using Joinpoint 4.8.0.1 software to observe the average annual percentage change (AAPC). Rstudio software was used to analyze the Spearman correlation between the age-standardized incidence of burns and SDI from 1990 to 2019. The global inequities of burn incidence were evaluated using the slope index and concentration index from the health equity assessment toolkit, where the slope index reflected the absolute difference in burn incidence between countries with the lowest and highest SDI, and the concentration index indicated the degree to which burn incidence was concentrated in countries with low or high SDI.Results:From 1990 to 2019, the number of global burncases increased from 8 378 121.71 to 8 955 227.68, with an increase of 6.89%. However, the age-standardized incidence rate of burns showed an overall downward trend, from 149.86/100 000 in 1990 to 117.51/100 000 in 2019, with an AAPC of -0.80%. The incidence of burns in the population aged 10-19 years ranked the first in all age groups during the 30 years. Among the six regions of the world, the number of burn cases and the age-standardized incidence rate of burn in the Americas were the highest in 2019, but these two indexes were lower than those in 1999. In 2019, the number of burn patients in medium SDI areas was the highest, and the number of burn patients in low SDI areas was the lowest. The age-standardized incidence of burns was the highest in high SDI areas, and the lowest in medium-low SDI areas. From 1990 to 2019, the number of patients in high and medium-high SDI areas decreased, and the number of patients in other SDI areas increased. Compared with 1990, the age-standardized incidence rates of burns decreased in all SDI regions in 2019, with the greatest decline seen in high SDI and medium-high SDI regions. Cuba had the highest standardized incidence of burns, while Pakistan had the lowest. Spearman correlation analysis showed that from 1990 to 2019, the age-standardized incidence rates of burns in 204 countries and regions were positively correlated with SDI (all P<0.05), and the correlation coefficient decreased from 0.49 in 1990 to 0.37 in 2019. The health inequality slope index decreased from 212.90/100 000 in 1990 to 59.12/100 000 in 2019, and the concentration index decreased from 21.77% in 1990 to 8.38% in 2019. Conclusion:From 1990 to 2019, the global burn incidence rates are disproportionately concentrated in countries and regions with better development status. A significant reduction in the global burn incidence has been accompanied by a significant reduction in these inequities.

Objective:To compare the effects of enhanced heat preservation strategies and conventional heat preservation strategies in the operation room on body temperature, coagulation function, and myocardial injury in patients with cervical spinal cord injuries.Methods:A retrospective cohort study was conducted to analyze the clinical data of 160 patients with cervical spinal cord injuries admitted to Second Affiliated Hospital of Xi′an Jiaotong University and Affiliated Honghui Hospital of Xi′an Jiaotong University from February to October 2022, including 82 males and 78 females, aged 38-64 years [(50.6±8.7)years]. Injured segments included C 3 in 19 patients, C 4 in 33, C 5 in 39, C 6 in 38, and C 7 in 31. According to American Spinal Injury Association (ASIA) classification, 10 patients were classified into grade A, 83 grade B, 39 grade C, and 28 grade D. All the patients underwent cervical laminoplasty, decompression and bone graft fusion surgery. According to different heat preservation strategies intraoperatively, the patients were divided into conventional heat preservation group ( n=80) and enhanced heat preservation group ( n=80). The body temperature changes before surgery, at 2 hours during surgery, immediately after surgery, at 2 and 24 hours after surgery were compared between the two groups. The changes of coagulation function before surgery and at 4 hours after surgery were compared between the two groups, including the prothrombin time (PT), thrombin time (TT), and activated partial thromboplastin time (APTT). The incidence of myocardial injury and the number of patients with myocardial injury measured by the indicators of cardiac troponin I (cTnI) and high-sensitivity cardiac troponin T (hs-cTnT) at 48 hours after surgery. Before surgery and at 14 days after surgery, ASIA classification was used to evaluate the neurological functions, including sensory and motor functions between the two groups. The incidence of cardiovascular events at 12 months after surgery were compared between the two groups. Results:A total of 145 patients were followed up for 12-18 months [(15.7±1.6)months]. At 12 months after operation, there were 7 patients in the enhanced heat preservation group were lost to follow-up, compared to 8 patients in the conventional heat preserration group. There was no statistically significant difference in body temperature between the two groups before surgery or at 24 hours after surgery ( P>0.05). At 2 hours during surgery, immediately after surgery and at 2 hours after surgery, the body temperature was (36.90±0.12)℃, (37.00±0.06)℃, and (37.16±0.06)℃ in the enhanced heat preservation group, which were significantly higher than those in the conventional heat preservation group [(36.56±0.03)℃, (36.74±0.08)℃, and (36.84±0.08)℃] ( P<0.01). The serum levels of PT, TT and APTT were not significantly different between the two groups before surgery ( P>0.05), while they were (13.1±1.2)seconds, (19.2±1.1)seconds, and (36.2±3.3)seconds in the enhanced heat preservation group at 4 hours after surgery, which were significantly lower than those in the conventional heat preservation group [(14.3±1.0)seconds, (20.2±1.1)seconds, and (38.7±3.4)seconds] ( P<0.01). The incidence of myocardial injury in the enhanced heat preservation group was 5.0% (4/80) at 48 hours after surgery, which was lower than 12.5% (12/80) in the conventional heat preservation group ( P<0.05). With cTnI as the indicator of myocardial injury, there were 2 patients [2.6%(2/76)] with myocardial injury in the enhanced heat preservation group, which was much lower than 8 patients [11.8%(8/68)] in the conventional heat preservation group ( P<0.05). With hs-cTnT as the indicator of myocardial injury, 8 patients [10.5%(8/76)] in the enhanced heat preservation group experienced myocardial injury, similar with 10 patients [14.7%(10/68)] in the conventional heat preservation group ( P>0.05). There were no statistically significant differences in the ASIA scores of the sensory and motor functions between the two groups before surgery and at 14 days after surgery ( P>0.05). The incidence of cardiovascular events at 12 months after surgery in the conventional heat preservation group was 27.8% (20/72), which was significantly higher than 9.6% (7/73) in the enhanced heat preservation group ( P<0.01). Conclusion:For patients with cervical spinal cord injuries, compared with conventional heat preservation strategies, the enhanced heat preservation strategies in the operating room can improve the patients′ core body temperature and coagulation function, and significantly reduce the incidence of myocardial injury and cardiovascular events.

Over-expression of glutathione S-transferase(GST)can promote Cisplatin resistance in hepatocellular carcinoma(HCC)treatment.Hence,inhibiting GST is an attractive strategy to improve Cisplatin sensi-tivity in HCC therapy.Although several synthesized GST inhibitors have been developed,the side effects and narrow spectrum for anticancer seriously limit their clinical application.Considering the abundance of natural compounds with anticancer activity,this study developed a rapid fluorescence technique to screen"green"natural GST inhibitors with high specificity.The fluorescence assay demonstrated that schisanlactone B(hereafter abbreviated as C1)isolated from Xue tong significantly down-regulated GST levels in Cisplatin-resistant HCC cells in vitro and in vivo.Importantly,C1 can selectively kill HCC cells from normal liver cells,effectively improving the therapeutic effect of Cisplatin on HCC mice by down-regulating GST expression.Considering the high GST levels in HCC patients,this compound demon-strated the high potential for sensitizing HCC therapy in clinical practice by down-regulating GST levels.
