RESUMO

ObjectiveTo investigate the effect and mechanism of Shenqi Tangluo pill (SQTLP) on oxidative stress injury of skeletal muscle of type 2 diabetes mellitus (T2DM) mice based on nuclear factor erythroid 2-related factor 2 (Nrf2)/heme oxygenase-1 (HO-1)/NAD(P)H quinone oxidoreductase 1 (NQO1) pathway. MethodA total of 60 7-week-old male db/db mice [specific pathogen-free (SPF) grade] were selected and fed for one week for adaption. They were divided into the model control group, SQTLP low-, medium- and high-dose (19, 38, and 76 g·kg-1) groups and metformin group (0.26 g·kg-1) by gavage. Each group consisted of 12 mice. Twelve male db/m mice of the same age were selected as the blank group. The intervention was implemented continuously for 8 weeks. Fasting blood glucose (FBG) was detected. Fasting serum insulin (FINS) levels were detected by enzyme-linked immunosorbent assay (ELISA), and the homeostasis model assessment-insulin resistance (HOMA-IR) index and the homeostasis model assessment-insulin sensitivity index (HOMA-ISI) were calculated. Oral glucose tolerance test (OGTT) and insulin tolerance test (ITT) were conducted. The activities of superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) and the contents of malondialdehyde (MDA) and reduced nicotinamide adenine dinucleotide phosphate (NADPH) in skeletal muscle tissues were detected by biochemical kits. Hematoxylin-eosin (HE) staining was used to observe the pathological changes in skeletal muscle tissues. The levels of reactive oxygen species (ROS) and 4-hydroxynonenal (4-HNE) in skeletal muscle tissue were detected by immunofluorescence (IF). The expression levels of Nrf2, HO-1, NQO1 and glutamate-cysteine ligase catalytic subunit (GCLC) proteins in skeletal muscle tissues were detected by Western blot. ResultCompared with those in the blank group, FBG, FINS and HOMA-IR in the model group were significantly increased (P<0.05), while HOMA-ISI was decreased (P<0.05). The results of OGTT and ITT showed that blood glucose was significantly increased at all time points (P<0.05), and glucose tolerance and insulin tolerance were significantly impaired. SOD and GSH-Px activities in skeletal muscle tissues were significantly decreased (P<0.05), and MDA and NADPH contents were significantly increased (P<0.05). In skeletal muscle tissues, the arrangement of muscle fibers was loose, the nucleus was disordered, and inflammatory cells were infiltrated. The expression levels of ROS and 4-HNE in skeletal muscle tissues were significantly increased (P<0.05). The protein expression levels of Nrf2, HO-1, NQO1 and GCLC in skeletal muscle tissues were significantly decreased (P<0.05). Compared with those in the model group, FBG, FINS and HOMA-IR in the metformin group were significantly decreased (P<0.05), while HOMA-ISI was increased (P<0.05). The results of OGTT and ITT showed that blood glucose in the metformin group was significantly decreased at all time points (P<0.05). The activities of SOD and GSH-Px in skeletal muscle tissues were significantly increased (P<0.05), while the contents of MDA and NADPH were significantly decreased (P<0.05). No obvious abnormality was found in the skeletal muscle tissue of the metformin group. The expressions of ROS and 4-HNE in skeletal muscle tissues were decreased (P<0.05). The protein expression levels of Nrf2, HO-1, NQO1 and GCLC in skeletal muscle tissues were significantly increased (P<0.05). Compared with those in the model group, FBG, FINS and HOMA-IR in the SQTLP medium- and high-dose groups were significantly decreased (P<0.05), while HOMA-ISI was increased (P<0.05). The results of OGTT and ITT showed that the glucose tolerance and insulin tolerance of mice were improved in each dose group of SQTLP. The GSH-Px activity in the SQTLP low-dose group was significantly increased (P<0.05), and the NADPH content was decreased (P<0.05). The activities of SOD and GSH-Px in the SQTLP medium- and high-dose groups were significantly increased (P<0.05), while the contents of MDA and NADPH were significantly decreased (P<0.05). The skeletal muscle tissue injury of mice in each dose group of SQTLP was ameliorated to different degrees. In the SQTLP medium- and high-dose groups, the expressions of ROS and 4-HNE were decreased (P<0.05), and the protein expression levels of Nrf2, HO-1, NQO1 and GCLC were significantly increased (P<0.05). Compared with those in the SQTLP low-dose group, FBG and HOMA-IR in the SQTLP high-dose group were significantly decreased (P<0.05), while HOMA-ISI was increased (P<0.05). The results of OGTT and ITT showed that the SQTLP high-dose group significantly improved the glucose tolerance and insulin tolerance of mice. The activities of SOD and GSH-Px in skeletal muscle tissues were significantly increased (P<0.05), while the contents of MDA and NADPH were significantly decreased (P<0.05). No obvious abnormality was found in the skeletal muscle tissue, the expressions of ROS and 4-HNE were decreased (P<0.05), and the protein expression levels of Nrf2, HO-1, NQO1 and GCLC were significantly increased (P<0.05) in the skeletal muscle tissue of the SQTLP high-dose group. ConclusionSQTLP can significantly improve IR in T2DM mice, and the mechanism is related to SQTLP activating the Nrf2/HO-1/NQO1 signaling pathway, promoting the expression of antioxidant enzymes, and thus improving the oxidative stress injury in the skeletal muscle.

RESUMO

ObjectiveTo explore the intervention mechanism of Xiangsha Liujunzi Tang in rats with functional dyspepsia (FD) based on the Ras homolog gene family member A (RhoA)/Rho-associated coiled-coil containing protein kinase 2 (ROCK2)/Myosin phosphatase target Subunit 1 (MYPT1) pathway. MethodSixty male SD suckling rats in SPF grades were randomly divided into blank group (n=10) and model group (n=50). The comprehensive modeling method (gavage administration of iodoacetamide+exhaustion of swimming+disturbance of hunger and satiety) was used to replicate the rat model of FD. After successful replication of the model, the rats in the model group were randomly divided into model group, mosapride group, and high, middle, and low-dose Xiangsha Liujunzi Tang groups, with 10 rats in each group. Rats in the blank group and model group were given 10 mL kg-1·d-1 normal saline, those in the mosapride group were given 1.35 mg·kg-1·d-1 mosapride, and those in the high, middle, and low-dose Xiangsha Liujunzi Tang groups were given 12, 6, and 3 g·kg-1·d-1 Xiangsha Liujunzi Tang, respectively. The intervention lasted 14 days. The general living conditions of rats were observed before and after modeling and administration, and the 3-hour food intake and body mass of rats were measured. After intervention, the intestinal propulsion rate of rats was measured, and the pathological changes in the gastric tissue were observed by hematoxylin-eosin (HE) staining. The content of choline acetyl transferase (ChAT) and vasoactive intestinal peptide (VIP) in the medulla oblongata and gastric tissue homogenate was determined by enzyme-linked immunosorbent assay (ELISA), the distribution of adenosine triphosphate (ATP) enzyme in gastric antrum smooth muscle was observed by frozen section staining, and the protein expression levels of RhoA, ROCK2, and phosphorylated-myosin phosphatase target subunit 1 (p-MYPT1) in the gastric tissue were detected by Western blot. ResultCompared with the blank group, the model group had withered hair, lazy movement, slow action, poor general living condition, lower 3-hour food intake, body mass, and lower intestinal propulsion rate (P<0.05), whereas no obvious abnormality in gastric histopathology. In the model group, the content of ChAT in the medulla oblongata and gastric tissue decreased, the content of VIP in gastric tissue increased, the distribution of ATP enzyme in gastric antrum smooth muscle decreased significantly, and the protein expression levels of RhoA, ROCK2, and p-MYPT1 in the gastric tissue decreased significantly (P<0.05). As compared with the model group, the general living condition of rats in each intervention group was significantly improved, and the 3-hour food intake, body mass, and intestinal propulsion rate were significantly increased (P<0.05). There was no significant difference in gastric pathology in the intervention groups. The content of ChAT in the medulla oblongata and gastric tissue increased significantly, the content of VIP in the gastric tissue decreased, the distribution of ATP enzyme in gastric antrum smooth muscle increased significantly, and the protein expression levels of RhoA, ROCK2, and p-MYPT1 in the gastric tissue increased significantly (P<0.05). The intervention effect of Xiangsha Liujunzi Tang group on the above indexes was dose-dependent. ConclusionXiangsha Liujunzi Tang can effectively improve the general living condition and gastric motility of rats with FD, and its specific mechanism may be related to the activation of the RhoA/ROCK2/MYPT1 pathway in the gastric tissue to regulate smooth muscle relaxation and contraction and promote gastric motility.

RESUMO

ObjectiveTo explore the anti-tumor effect and mechanism of Shenqi Yiliu prescription in the intervention of pyroptosis. MethodTen male BALB/c mice were randomly selected and assigned to the blank group. The remaining 40 mice underwent the induction of the liver cancer xenograft model. After 5 days of modeling, 40 surviving mice were randomly divided into model group, cisplatin group [2.5×10-3 g·kg-1·(3 d)-1], Shenqi Yiliu prescription group (27 g·kg-1·d-1), and a combination group (Shenqi Yiliu prescription group + cisplatin). The mice in the blank group and the model group were treated with an equal volume of normal saline for 10 days. The general conditions of mice in each group were observed. After the intervention, the tumor weight of the mice was weighed and the tumor inhibition rate was calculated. Hematoxylin-eosin (HE) staining was used to observe the pathological changes in tumor tissues. The levels of mouse liver function indicators, including alanine aminotransferase (ALT) and aspartate aminotransferase (AST) were detected. The TdT-mediated dUTP-biotin nick end labeling (TUNEL) assay was used to detect DNA damage in mouse tumor tissue cells. Immunohistochemistry (IHC), immunofluorescence (IF), and Western blot were used to detect the protein expression levels of NOD-like receptor protein 3 (NLRP3), cysteinyl aspartate-specific protease-1 (Caspase-1), and gasdermin D (GSDMD) in tumor tissues. The levels of interleukin-1β (IL-1β) and interleukin-18 (IL-18) in tumor tissues were detected by enzyme-linked immunosorbent assay (ELISA). ResultCompared with the mice in the blank group, those in the model group were in a poor mental state, sleepy, and lazy, and their fur color was dull, with increased levels of serum ALT and AST in liver function tests (P<0.01). Compared with the model group, the groups with drug intervention showed improved mental state, inhibited tumor growth to varying degrees, and decreased tumor weight, and the tumor inhibition rate in the combination group was the highest (P<0.01). HE staining showed that the pathological and morphological lesions of the tumor tissues in the model group were significant, while those in all groups with drug intervention were improved to a certain extent. The karyolysis and nuclear rupture in the Shenqi Yiliu prescription group and the combination group were more significant. In the liver function test, the serum ALT and AST levels of mice in the Shenqi Yiliu prescription group and the combination group decreased (P<0.01), and the inflammatory factors IL-1β and IL-18 in each group with drug intervention decreased (P<0.05, P<0.01). Among them, the declining trend of IL-1β and IL-18 in the Shenqi Yiliu prescription group was the most significant (P<0.01). TUNEL staining showed that the positive TUNEL staining in each group with drug intervention decreased after intervention (P<0.05, P<0.01), especially the cisplatin group and Shenqi Yiliu prescription group (P<0.01). Western blot, IHC, and IF found that the protein expression levels of NLRP3, Caspase-1, and GSDMD in each group with drug intervention decreased (P<0.05, P<0.01). Compared with the mice in the cisplatin group, those in the Shenqi Yiliu prescription group and the combination group had better mental state and regular tumor morphology, and the tumor weight of the mice in the combination group decreased (P<0.05). The levels of ALT and AST in the Shenqi Yiliu prescription group decreased (P<0.05), and the levels of IL-1β and IL-18 in the Shenqi Yiliu prescription group and the combination group decreased (P<0.05, P<0.01), especially in the combination group (P<0.01). The results of IHC showed that the expression of GSDMD protein in the tumor tissues of mice in the combination group was reduced (P<0.01). IF detection showed that the expression of NLRP3 in the tumor tissues of the Shenqi Yiliu prescription group was reduced (P<0.01). The results of Western blot showed that the expression level of NLRP3 protein in the Shenqi Yiliu prescription group and the combination group decreased (P<0.01), and the expression level of Caspase-1 protein in the combination group decreased (P<0.01). The decrease in GSDMD protein expression was not significant, and the difference was not statistically significant. ConclusionShenqi Yiliu prescription combined with cisplatin has an obvious anti-tumor effect, which may be achieved by down-regulating the NLRP3/Caspase-1/GSDMD inflammatory pyroptosis pathway to inhibit cell pyroptosis, and relieve the inflammatory response in mice with liver cancer.
