OBJECTIVE To explore the effects of Polygala tenuifolia compatibility on toxicity, anti-inflammatory and analgesic efficacy of sand-ironing Strychnos nux-vomica (SS). METHODS The preparation of SS single decoction, SS-P. tenuifolia core-removed (PC) (1∶2.5) or (1∶5) combined decoction, and SS-PC (1∶5) mixture were carried out to investigate their median lethal dose (LD50). Using aspirin as positive control, the number of writhing movements, analgesic rate, pain latency, ear swelling degree and inflammation inhibition rate induced by the above-mentioned medicinal liquids in mice were compared. The contents of the active and toxic components, strychnine and brucine, in the above-mentioned medicinal liquids were also determined. RESULTS The LD50 values of SS single decoction, SS-PC (1∶2.5) combined decoction, SS-PC (1∶5) combined decoction and SS- PC (1∶5) mixture were 302.00, 614.47, 1 445.44 and 1 778.28 mg/kg, respectively. Compared with control group, the number of writhing movements and ear swelling degree in the mice of the above-mentioned medicinal liquid groups were reduced or decreased significantly (P<0.05 or P<0.01); pain latency [at 90 and 120 minutes in the SS single decoction group, at 60 and 90 minutes in the SS-PC (1∶2.5) combined decoction group, and at 60,90, 120 minutes in the SS-PC (1∶5) combined decoction group and SS-PC (1∶5) mixture group] was significantly prolonged (P<0.05 or P<0.01); analgesic rates of the respective medicinal liquids were 39.30%, 70.87%, 80.00% and 82.46%, and inflammation inhibition rates were 38.08%,TD 57.89%, 76.47% and 50.46%; analgesic and anti-inflammatory effects of combined decoction and mixture were generally better than those of the single decoction (P<0.05 or P<0.01). In the above-mentioned four medicinal liquids, the total contents of strychnine were 0.71%, 0.42%, 0.47% and 0.64%, and the total contents of brucine were 0.88%, 0.63%, 0.57% and 0.88%, respectively. CONCLUSIONS The combination of P. tenuifolia can reduce the toxicity of SS and enhance its anti-inflammatory and analgesic effects. Moreover, there is a tendency for the toxicity-reducing and efficacy-enhancing effects to increase with the increasing dosage of P. tenuifolia. Additionally, the combined decoction of SS and P. tenuifolia can reduce the contents of the active and toxic components, strychnine and brucine, in SS.

Hepatic encephalopathy (HE) is a common severe liver disease syndrome in clinical practice and is one of the critical and severe diseases in internal medicine, and more than half of liver failure patients diagnosed with overt HE have a survival time of less than 1 year. A comprehensive analysis of the complex pathogenesis of HE and the development of diagnosis and treatment regimens based on evidence-based medicine are of great importance for alleviating high medical resource consumption, high medical expenses, and high incidence and mortality rates in clinical practice. The latest studies have shown that the intestinal tract and the central nervous system can perform bidirectional continuous interaction and signal transmission and regulate the function of inflammation signals, molecules, cells, and organs, which is known as neuroimmune communication and is highly consistent with the main pathological features of HE. With a focus on the mechanism of neuroimmune communication in HE, this article reviews the association between inflammation signal transduction via the gut-brain axis and neurotransmitter regulation and its role in neuroimmune communication in HE, which provides new ideas for the clinical diagnosis and treatment of HE and the research and development of related drugs.

Objective:To observe the therapeutic effect of Shengsan Jiedu Huayu decoction in alleviating inflammatory liver injury in rats with acute-on-chronic liver failure (ACLF) and its effect on the activation intensity for the NLRP3 signaling pathway.Methods:63 SD rats were randomly divided into a blank group, a model group, and low-, medium-, and high-dose groups of Shengsan Jiedu Huayu decoction (7.29 g/kg/d, 14.58 g/kg/d, and 29.16 g/kg/d). The ACLF rat model was replicated using carbon tetrachloride combined with d-galactosamine and lipopolysaccharide. Different dose gradients of the Shengsan Jiedu Huayu decoction were used for a five-day intervention treatment, and then rat serum and tissue samples were collected. A biochemical analyzer was used to detect the serum levels of ALT, AST, and TBIL in rats. ELISA was used to detect serum IL-18 and IL-1β content. HE staining was used to observe histomorphological changes in liver tissue. Immunohistochemistry was used to detect GSDMD expression in liver tissue. Western blot and PCR were used to detect NLRP3, Caspase1, ASC, TLR4, IL-1β, IL-18 protein, and mRNA expression levels.The groups were compared using analysis of variance and the rank-sum test.Results:Compared with the blank group, the model group’s rat liver tissue was severely injured. Serum levels of ALT, AST, and TBIL, inflammatory factors IL-1β and IL-18, and the GSDMD protein expression level, NLRP3 expression level, TLR4, caspase 1, ASC, IL-1β, IL-18 protein, and mRNA ( P<0.01) were all significantly increased in the model than the blank group ( P<0.01). Additionally, compared with the model group, the low-, medium-, and high-dose groups of Shengsan Jiedu Huayu decoction had improved liver tissue injury in ACLF rats, while the serum levels of ALT, AST, TBIL, IL-1β, IL-18, liver tissue GSDMD protein, NLRP3, TLR4, caspase 1, and ASC expressions were all lower in the different dose gradients of the Shengsan Jiedu Huayu decoction than the model group, with the most evident reduction in the high-dose group ( P<0.01). Conclusion:Shengsan Jiedu Huayu decoction can weaken the activation intensity of the NLRP3 signaling pathway, alleviate liver tissue pathological injury, reduce inflammatory factor release, and alleviate inflammatory liver injury in ACLF rats.

To develop a novel glucose-lowering biomedicine with potential benefits in the treatment of type 2 diabetes, we used the 10rolGLP-1 gene previously constructed in our laboratory and the CRISPR/Cas9 genome editing technique to create an engineered Saccharomyces cerevisiae strain. The gRNA expression vector pYES2-gRNA, the donor vector pNK1-L-PGK-10rolGLP-1-R and the Cas9 expression vector pGADT7-Cas9 were constructed and co-transformed into S. cerevisiae INVSc1 strain, with the PGK-10rolGLP-1 expressing unit specifically knocked in through homologous recombination. Finally, an S. cerevisiae strain highly expressing the 10rolGLP-1 with glucose-lowering activity was obtained. SDS-PAGE and Western blotting results confirmed that two recombinant strains of S. cerevisiae stably expressed the 10rolGLP-1 and exhibited the desired glucose-lowering property when orally administered to mice. Hypoglycemic experiment results showed that the recombinant hypoglycemic S. cerevisiae strain offered a highly hypoglycemic effect on the diabetic mouse model, and the blood glucose decline was adagio, which can avoid the dangerous consequences caused by rapid decline in blood glucose. Moreover, the body weight and other symptoms such as polyuria also improved significantly, indicating that the orally hypoglycemic S. cerevisiae strain that we constructed may develop into an effective, safe, economic, practical and ideal functional food for type 2 diabetes mellitus treatment.
