Objective:To investigate the effect of inspiratory muscle training on the lung function and diaphragm movement of stroke survivors.Methods:Twenty-four stroke survivors were randomly divided into a control group and an experimental group. Both groups were given routine rehabilitation therapy, while the experimental group was additionally provided with 20 minutes of inspiratory muscle training, 5 times per week for 4 weeks. Before and after the treatment, the forced vital capacity (FVC), forced expiratory volume in one second (FEV1) and peak expiratory flow (PEF) expressed as percentages of the predicted values were used to assess ventilation. The maximum inspiratory pressure (MIP) and peak inspiratory flow (PIF) were used to assess inspiratory muscle function. Diaphragm mobility, as well as the diaphragm′s thickness at the end of expiration (DTee) and inspiration (DTei) and the diaphragm thickening fraction (DTF) were measured using ultrasonography. Any pulmonary infection was also recorded.Results:There was no significant difference between the two groups in any of the measurements before treatment. After the intervention the average FVC, FEV1, MIP, PIF, diaphragm mobility, DTei and DTF of the experimental group were all significantly better than before treatment and significantly better than the control group′s averages. However, no significant difference was found in the average PEF or DTee, nor in the rate of pulmonary infection between the two groups.Conclusion:Inspiratory muscle training can effectively improve ventilation, inspiratory muscle function, diaphragm mobility and diaphragm thickness at the end of inspiration among stroke survivors.

Objective To investigate the protective effects of Zhige Jiejiu Baogan Fang(Semen Hoveniae and Radix Puerariae Lobatae hangover-relieving and liver-protecting recipe, ZGJJBGF) on superoxide dismutase (SOD), malondialdehyde (MDA) and glutathione (GSH) rats with alcoholic liver injury. Methods 180 male Wistar rats were randomly divided into 6 groups: blank group, model group, positive control (Compound Methionine and Choline Bitartrate Tablet) group (0.36 g/kg), high-dose, mid-dose and low-dose ZGJJBGF groups (18,9,1.8 g/kg respectively). Except for the blank group, rats in other groups were orally administered with 50% ethanol(diluted with distilled water) for 6 weeks to establish the alcoholic liver injury rat model. Rats in all experimental groups except the blank and model groups received medicinal intervention respectively. The activity of malondialdehyde (MDA), glutathione (GSH),and superoxide dismutase(SOD) in serum and liver were measured at the end of the experiment. Results SOD activity in model group was significantly lower than that in the blank group, and the contents of MDA and GSH in the liver tissues and blood were significantly higher in the blank group (P<0.01). Compared with model group, mid-dose ZGJJBGF significantly increased the serum GSH level (P<0.05) and the activity of SOD (P<0.01) while reducing the content of MDA in liver tissue(P<0.01). Compared with the model group,high-dose ZGJJBGF significantly reduced the content of MDA in liver tissue of rats(P<0.01) and increased the content of GSH(P<0.01). Compared with model group, low-dose ZGJJBGF reduced serum MDA content (P<0.01). Conclusion Zhige Jiejiu Baogan Fang could enhance the antioxidant ability of endogenous antioxidant enzymes such as SOD and GSH. It can also inhibit the damage of liver injury of free radical-induced lipid peroxidation.

ObjectiveTo observe the effect of Hoveniae Semen, Flos Puerariae and their combinations on acute alcoholic liver disease and provide a scientific basis for the drug use in clinical practice and the research on other alcoholic diseases. MethodThe acute alcoholic liver injury model of mice was established by one-time gavage with 56% (V/V) Hongxing Erguotou liquor (12 mL·kg-1). One hundred and twenty male ICR mice were randomly assigned into blank group, model group, silybin group, Flos Puerariae group, Hoveniae Semen group, and Flos Puerariae-Hoveniae Semen combination groups (ratios of 1∶1, 1∶2 and 2∶1, respectively), with 15 mice in each group. Each group was administrated with 10 mL·kg-1 corresponding preventive drugs for 3 days by gavage. Except the blank group, the other groups were given Erguotou liquor by gavage at 12 mL·kg-1. The mice were sacrificed 12 h after drinking for the observation of liver function and oxidative stress. The pathological changes of liver were observed via hematoxylin-eosin (HE) staining. Western blot was employed to determine the expression levels of proteins in the Kelch-like Ech-associated protein 1 (Keap1)/nuclear factor E2-related factor 2 (Nrf2)/antioxidant response element (ARE) signaling pathway. Real-time fluorescence quantitative polymerase chain reaction (Real-time PCR) was used to detect mRNA levels of related genes. ResultCompared with control group, the modeling elevated the levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST) and alkaline phosphatase (ALP) in the serum and the content of malondialdehyde (MDA) and reactive oxygen species (ROS) in liver tissue (P<0.01) and decreased the activities of glutathione (GSH) and superoxide dismutase (SOD) (P<0.01). The mRNA and protein expressions of Keap1 were significantly increased (P<0.05,P<0.01), mRNA and protein expressions of Nrf2 were significantly decreased (P<0.01). Compared with model group, Flos Puerariae-Hoveniae Semen 2∶1 lowered the levels of ALT, AST and ALP in the serum (P<0.01) and MDA and ROS in the liver (P<0.01), and increased the activities of GSH and SOD (P<0.01). Moreover, it alleviated the hepatic steatosis injury, up-regulated mRNA and protein levels of Nrf2 (P<0.01), and down-regulated the mRNA and protein levels of Keap1 (P<0.01). ConclusionFlos Puerariae, Hoveniae Semen and their combinations may exert the pre-protective effect on acute alcoholic liver injury in mice by regulating the Keap1/Nrf2/ARE pathway in the liver and restoring the liver oxidative balance destroyed by ethanol to inhibit the development of alcoholic liver disease .

ObjectiveTo observe the effects of Sargassum and Glycyrrhizae Radix et Rhizoma incompatible pair with the Haizao Yuhutang (HYT) on oxidative stress in the liver of goiter rats under the condition of 2 times the dose limit of the Pharmacopoeia of the People's Republic of China 2020. MethodA total of 128 male Wistar rats were randomly divided into a blank group, a model group, a euthyrox group (20 μg·kg-1), a HYT group (12.06 g·kg-1), a HYT without Sargassum (HYT-H) group (9.90 g·kg-1), a HYT without Glycyrrhizae Radix et Rhizoma (HYT-G) group (10.26 g·kg-1), a HYT without Sargassum and Glycyrrhizae Radix et Rhizoma (HYT-HG) group (8.10 g·kg-1), and a Sargassum and Glycyrrhizae Radix et Rhizoma (HG) group (3.96 g·kg-1). The blank group was given deionized water by gavage, and the others were given propylthiouracil (PTU) to replicate the goiter pathological model. Euthyrox was taken as a positive control drug, and the rest of the Chinese medicine groups were given the corresponding decoction by gavage, the material was collected 12 hours after the last dose. The serum levels of aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), and the contents of superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), malondialdehyde (MDA), reactive oxygen species (ROS) in liver tissue were detected in each group. The pathological changes in the liver were observed via hematoxylin-eosin (HE) staining. Real-time fluorescence quantitative polymerase chain reaction (Real-time PCR) was utilized to detect the mRNA expressions of Kelch-like Ech-associated protein 1 (Keap1), nuclear factor E2-related factor 2 (Nrf2), heme oxygenase-1 (HO-1), p53 and Caspase-3 in liver tissues. Western blot was adopted to detect the protein expressions of Nrf2 and HO-1 in liver tissues in oxidative stress-related signaling pathways. ResultCompared with control group, the model group showed significantly increased serum ALT level and contents of MDA and ROS in liver tissues (P<0.05, P<0.01), significantly reduced activities of SOD and GSH-Px in the liver (P<0.01), significantly increased mRNA expression of Keap1 (P<0.01), and significantly decreased mRNA and protein expressions of Nrf2 and HO-1 (P<0.05, P<0.01). Compared with the model group, the HYT group manifested significantly reduced serum levels of AST, ALT, and ALP (P<0.05, P<0.01), significantly reduced contents of MDA and ROS in liver tissue (P<0.01), significantly increased the activities of SOD and GSH-Px (P<0.01), significantly decreased mRNA expressions of Keap1, p53, and Caspase-3 (P<0.01), and significantly increased mRNA and protein expressions of Nrf2 and HO-1 (P<0.05, P<0.01). ConclusionUnder the condition of 2 times the dose limit of the Pharmacopoeia of the People's Republic of China 2020, Sargassum and Glycyrrhizae Radix et Rhizoma incompatible pair with the HYT on oxidative stress in the liver of goiter rats had different effects. The HYT that contains Sargassum and Glycyrrhizae Radix et Rhizoma has a protective effect on the liver of goiter rats, and the effect is better than that of the HG group, the euthyrox group, and the incomplete groups. Its mechanism may be related to activating the Nrf2/HO-1 signaling pathway to alleviate liver oxidative stress and inhibiting the p53/Caspase-3 signaling pathway to reduce hepatocyte apoptosis.
