Abstract
Aflatoxin B1 (AFB1) is one of the common dietary contaminants worldwide, which can harm the liver of humans and animals. Salvia miltiorrhiza polysaccharide (SMP) is a natural plant-derived polysaccharide with numerous pharmacological activities, including hepatoprotective properties. The purpose of this study is to explore the intervention effect of SMP on AFB1-induced liver injury and its underlying mechanisms in rabbits. The rabbits were administered AFB1 (25 μg/kg/feed) and or treatment with SMP (300, 600, 900 mg/kg/feed) for 42 days. The results showed that SMP effectively alleviated the negative impact of AFB1 on rabbits' productivity by increasing average daily weight gain (ADG) and feed conversion rate (FCR). SMP reduced aspartate aminotransferase (AST), alanine aminotransferase (ALT) and alkaline phosphatase (ALP) levels in serum, ameliorating AFB1-induced hepatic pathological changes. Additionally, SMP enhanced superoxide dismutase (SOD), catalase (CAT) and glutathione (GSH) activity, and inhibited reactive oxygen species (ROS), malondialdehyde (MDA), 4-Hydroxynonenal (4-HNE), interleukin-1β (IL-1β), interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) expression, thus mitigating AFB1-induced oxidative stress and inflammatory responses. Moreover, SMP upregulated the expression of nuclear factor E2 related factor 2 (Nrf2), heme oxygenase 1 (HO-1), NADPH quinone oxidoreductase 1 (NQO1) and B-cell lymphoma 2 (Bcl2) while downregulating kelch like ECH associated protein 1 (Keap1), cytochrome c (cyt.c), caspase9, caspase3, and Bcl-2-associated X protein (Bax) expression, thereby inhibiting AFB1-induced hepatocyte apoptosis. Consequently, our findings conclude that SMP can mitigate AFB1-induced liver damage by activating the Nrf2/HO-1 pathway and inhibiting mitochondria-dependent apoptotic pathway in rabbits.

Abstract
Plant polysaccharides as immunomodulators are considered one of the effective measures to reduce antibiotic therapy in aquaculture. The immunomodulatory function of Salvia miltiorrhiza polysaccharides (SMP) has been demonstrated and begun to be applied in vertebrates, but its potential effect on crustaceans is unclear. In this study, crayfish (Procambarus clarkii) was fed with 0 %, 0.3 %, 0.7 %, 1.1 %, and 1.5 % SMP for 4 weeks to investigate the effects of SMP on hemocytes phagocytosis, hepatopancreatic function, and intestinal barrier function. The results revealed that hemocyte phagocytic activity was increased in all SMP groups. During the process of hemocytes phagocytic recognition and formation of phagosomes and phagolysosomes, the mRNA expression levels of mas, hem, rab3, ctsb, and lamp-1 were up-regulated mainly in the 0.3 % SMP group. During the clearance phase of phagocytosis, respiratory burst activity, ROS level, T-SOD, CAT, GST, and LZM activities were mainly increased in the 1.5 % SMP group. Hepatopancreas AKP and GOT activity were no significant change in all SMP groups. ACP activity was significantly enhanced in the 1.1 % SMP group. The GPT activity of 0.3-0.7 % SMP group was significantly decreased. The 0.7 % SMP group had the highest intestinal fold height. The highest index values of OTUs, Ace, Chao, and Shannon were in the 0.3 % SMP group. The dietary addition of 0.3 % SMP led to a tendency of increased relative abundance of Firmicutes and Bacteroidota at the phylum level, while the relative abundance of Proteobacteria at the phylum level decreased. In conclusion, dietary SMP could promote crayfish health by enhancing phagocytosis, protecting hepatopancreas and enhancing intestinal barrier function. This study contributes to the theoretical foundation for exploring the potential application of plant polysaccharides in crustaceans.

Abstract
Natural plant polysaccharide as immune modulator is considered an effective strategy for healthy aquaculture to reduce medicine treatment. Salvia miltiorrhiza polysaccharides (SMP) had applications to regulate immune activity and enhance antioxidant in vertebrates, but the potential function has been rarely reported in crustaceans. In this study, the immunological effects of SMP on hemocytes of Procambarus clarkii were analyzed. Results showed that total superoxide dismutase (T-SOD), phenoloxidase (PO) activity and respiratory burst were up-regulated after SMP treatment. After high-throughput sequencing, 2170 differentially expressed genes (DEGs) including 1294 up-regulated and 876 down-regulated genes were identified. KEGG function enrichment analysis indicated that DEGs are involved in crustaceans cellular immune-related signaling pathways, including lysosome, phagosome and endocytosis. Transcriptome mining and qRT-PCR showed that SMP up-regulated humoral immunity factors gene expression. Diets supplemented with 0.8% SMP significantly up-regulated the total number of hemocytes (THC), T-SOD and PO activity, improved the survival of crayfish after Citrobacter freundii infection. This study suggested that SMP could improve the cellular and humoral immunity of P. clarkii. Furthermore, this finding supplied a molecular foundation for further comprehending the immunopotentiator effects of plant polysaccharides in crustaceans.

Abstract
The use of plant polysaccharides in aquaculture is recognized as a healthy strategy to enhance disease resistance and reduce medication use. Salvia miltiorrhiza polysaccharide (SMP) can regulate the immune function of higher vertebrates. However, the effects of SMP on fish have not been fully investigated. In this study, the ability of SMP to activate the macrophages of Siberian sturgeon (Acipenser bareii) was analyzed in vitro. The effects of SMP on immune cell activity of hybrid sturgeon (A. baerii ♀ × Acipenser schrenckii ♂) and resistance to Aeromonas hydrophila were further detected in vivo. The in vitro results showed that SMP up-regulated phagocytosis, respiratory burst, inducible nitric oxide synthase activity, nitric oxide (NO) concentration, and cytokine mRNA expression of macrophages. The in vivo results showed that dietary supplementation with SMP enhanced the respiratory burst of macrophages and proliferative activity of lymphocytes. Dietary supplementation with SMP increased serum concentrations of lysozyme and NO, and improved the survival rate of hybrid sturgeon challenged with A. hydrophila. Collectively, these results suggest that SMP can improve the immune function and disease resistance of sturgeon. This study provides a theoretical basis for the application of SMP for healthy farming of sturgeon.

Abstract
A microwave-assisted extraction procedure for the crude Salvia miltiorrhiza polysaccharides (SMPs) obtained from Salvia miltiorrhiza Bunge was optimized. Four independent variables were studied: microwave power, extraction time, solvent-to-solid ratio, and concentration of ethanol, with optimal settings of 1200 W, 12 min, 38, and 86 %, respectively. The SMPs were successively purified by DEAE Sepharose Fast Flow and Sephadex G-100 chromatography to produce a novel polysaccharide termed SMP1. The SMP1 was composed of glucose, galactose, and fructose in a molar ratio of 1:1.67:1.12 with an average molecular weight of 6087 Da. Pharmacological studies showed that SMP1 protected from OGD/R-induced ferroptosis and lipid peroxidation by activating Nrf2/HO-1 pathway in PC12 cells. Our research systematically indicated that polysaccharide could inhibit ferroptosis to alleviate oxidative stress injury, which laid the foundation for the future clinical application of Salvia miltiorrhiza polysaccharide.

Abstract
In order to explore the transcriptomics and proteomics targets and pathways of Salvia miltiorrhiza polysaccharides (SMPs) alleviating florfenicol (FFC)-induced liver injury in broilers, 60 1-day-old broilers were randomly divided into 3 groups: control group ( GP1) was fed tap water, FFC model (GP2) was given tap water containing FFC 0.15 g/L, and SMPs treatment group (GP3) was given tap water containing FFC 0.15 g/L and SMPs 5 g/L. Starting from 1 day of age, the drug was administered continuously for 5 days. On the 6th day, blood was collected from the heart and the liver was taken. Then 3 chickens were randomly taken from each group, and their liver tissues were aseptically removed and placed in an enzyme-free tube. Using high-throughput mRNA sequencing and TMT-labeled quantitative proteomics technology, the transcriptome and proteome of the three groups of broiler liver were analyzed, respectively. The results of the study showed that the liver tissue morphology of the chicks in the GP1 and GP3 groups was complete and there were no obvious necrotic cells in the liver cells. The liver tissue cells in the GP2 group showed obvious damage, the intercellular space increased, and the liver cells showed extensive vacuolation and steatosis. Compared with the GP1 group, the daily gain of chicks in the GP2 group was significantly reduced (P < 0.0 5 or P < 0.01). Compared with the GP2 group, the GP3 group significantly increased the daily gain of chicks (P <0.0 5 or P <0.01). Compared with the GP1 group, the serum levels of ALT, AST, liver LPO, ROS, and IL-6 in the GP2 group were significantly increased (P < 0.0 5 or P < 0.01), and the contents of T-AOC, GSH-PX, IL-4, and IL-10 in the liver were significantly decreased (P < 0.0 5 or P < 0.01). After SMPs treatment, the serum levels of ALT, AST, liver LPO, ROS, and IL-6 were significantly reduced (P < 0.0 5 or P < 0.01), and the contents of T-AOC, GSH-PX, IL-4, and IL-10 in the liver were significantly increased (P < 0.0 5 or P < 0.01). There were 380 mRNA and 178 protein differentially expressed between GP2 group and GP3 group. Part of DEGs was randomly selected for QPCR verification, and the expression results of randomly selected FABP1, SLC16A1, GPT2, AACS, and other genes were verified by QPCR to be consistent with the sequencing results, which demonstrated the accuracy of transcriptation-associated proteomics sequencing. The results showed that SMPs could alleviate the oxidative stress and inflammatory damage caused by FFC in the liver of chicken and restore the normal function of the liver. SMPs may alleviate the liver damage caused by FFC by regulating the drug metabolism-cytochrome P450, PPAR signaling pathway, MAPK signaling pathway, glutathione metabolism, and other pathways.

Abstract
This study investigated the effects of Salvia miltiorrhiza polysaccharides (SMPs) on the injury of chicken hepatocytes in vitro and in vivo. In in vitro studies primary cultured hepatocytes were isolated by 2-step collagenase perfusion. Carbon tetrachloride (CCL4) was added to the hepatocytes to establish a hepatocyte injury model. Hepatocytes were treated with different concentrations of SMPs to detect the protective effects of SMPs on CCL4-induced hepatocyte injury. The results of the control group showed that chicken hepatocytes grew well and their morphology was normal. After CCL4 treatment, the activity of alanine transaminase (ALT) and aspartate transaminase (AST) of hepatocytes increased compared with the normal control group. SMPs treatment downregulated the contents of ALT, AST, and malondialdehyde (MDA), and upregulated the contents of glutathione (GSH) and cytochrome P450 (CYP450). An acute chicken liver injury model was established in vivo with 2.0 mL/kg 50% CCL4. Oral administration of SMP at different doses exhibited preventive success. The results showed that compared with the control group, the contents of total protein (TP), albumin (Alb), and GSH in the liver injury model group were significantly decreased and the levels of liver index, ALT, AST, and MDA were significantly increased. In contrast, in the SMP group the contents of TP, Alb, and GSH were significantly increased, and the levels of liver index, ALT, AST, and MDA were significantly decreased compared with the model group. Therefore, we conclude that SMPs have good protective effect on chicken liver damage in vivo and in vitro.
