ABSTRACT
AIM:To explore the effects of genipin (GEN) on high glucose (HG) -induced oxidative stress injury and apoptosis in H9c2 cardiomyocytes.METHODS:H9c2 cells were cultured in vitro and HG-induced injury model was established.H9c2 cells were divided into 4 groups:normal control (NC) group (glucose at 5.6 mmol/L) , HG group (glucose at 50 mmol/L) , NG+GEN group and HG+GEN group.The concentration of genipin was used at 10μmol/L.The viability of the H9c2 cells was measured by CCK-8 assay.The intracellular malondialdehyde (MDA) content and superoxide dismutase (SOD) activity were determined by enzyme labeling and WST-1 methods, respectively.The activity of lactate dehydrogenase (LDH) in the cell culture supernatant was detected by microplate method.Fluorescent probe DCF was used to detect intracellular levels of reactive oxygen species (ROS).Nucleosome fragments was measured to evaluate cell apoptosis by ELISA.The intracellular mitochondrial membrane potential was detected by JC-1 method.The protein levels of Mn-SOD, cytochrome C (Cyt C) , Bax and cleaved caspase-3 were determined by Western blot.RESULTS:Compared with HG group, the cell viability in HG+GEN group was increased significantly (P<0.05) , the levels of MDA and LDH were decreased (P<0.05) , SOD activity was increased (P<0.05) , the levels of ROS and nucleosome fragments in HG+GEN group were decreased (P<0.05) , and the mitochondrial membranes potential was notably increased (P<0.05).Compared with NG group, the activation of Mn-SOD was decreased, but the protein levels of Cyt C, Bax and cleaved caspase-3 were increased in HG group (P<0.05).Compared with HG group, the activation of Mn-SOD was increased, and the protein levels of Cyt C, Bax and cleaved caspase-3 were decreased in HG+GEN group (P<0.05).CONCLUSION:Genipin protects HG-induced H9c2 cardiomyocytes against oxidative stress injury and apoptosis.
ABSTRACT
AIM:To observe the effects of ginsenoside Rh 1 on the levels of inflammatory factors in serum and bronchoalveolar lavage fluid(BALF),and the pathological changes of the lung tissues in an experimentally induced mouse asthma model.METHODS:Male BALB/c mice(n=40)were divided into 4 groups:normal control group,asthma mo-del group,and low-dose(40 mg· kg-1 · d-1 )and high-dose(80 mg· kg-1 · d-1 )ginsenoside Rh1 groups.The bron-chial asthma mouse model was established by the method of ovalbumin induction and excitation ,and during the excitation period,the mice were daily treated with ginsenoside Rh 1 for 2 weeks.At 24 h after the final dose of ginsenoside Rh 1,the mice were sacrificed.The number of eosinophils(EOS)and the concentrations of interleukin(IL)-4,IL-5 and interferon(IFN)-γin BALF were determined.The levels of IgG and IgE in serum were measured ,and the expression of transforming growth factor(TGF)-β1 and the pathological changes in lung tissues were evaluated.RESULTS:Ginsenoside Rh1 inhibi-ted the increases in the number of EOS and the concentrations of IL-4,IL-5,IFN-γand IgE,reversed the increased ex-pression of TGF-β1,and improved the pathological changes of the lung tissues in asthmatic mice.CONCLUSION:Gin-senoside Rh1 improves the immuno-inflammatory profile and pathological changes in the experimentally induced mouse asth -ma model,implying its potential therapeutic effect on asthma.
ABSTRACT
Objective To analyze the effect of bone peptide injection in patients with osteoarthritis of the activity of alkaline phosphatase. Methods A total of 74 patients with osteoarthritis of the bone were selected from March 2015 to May 2017 in our hospital and were randomly divided into two groups,with 37 cases in each group.The control group was treated with glucosamine sulfate, the observation group was treated with ossotide injection.The therapeutic effect and alkaline phosphatase activity were compared between two groups. Results The total effective rate was 97.30% in the observation group, which was significantly higher than that in the control group (70.27%) (P<0.05) .The score of knee function was (79.62±5.80) in the observation group.which was significantly higher than that in the control group (71.06±5.41) (P<0.05).The alkaline phosphatase activity after the treatment of 30d and 45d (0.97±0.12), nkat/L (1.39±0.12) nkat /L was significantly higher than the control group (0.71±0.10), nkat/L, (0.88±0.10) nkat/L, the incidence rate of adverse reaction(5.41 %) was significantly lower than the control group (24.32 %) (P<0.05). Conclusion Bone peptide injection has significant therapeutic effect on bone and joint osteoarthritis, can effectively improve the knee joint function of the patients, improve the patients with alkaline phosphatase activity, and high safety, is worthy of promotion.

ABSTRACT
To observe the inhibitive effect of Baicalin against influenza A H1N1 virus infection in epithelial cell line A549, the cell proliferation and cytotoxicity were assayed by MTT, the cell cycle and the apoptosis were analyzed by flowcytometer using PI staining, the morphology of cellular nucleolus was observed by Hoechst 33258 staining and the effects of activation on caspase 3 and caspase 8/9 were also detected by immunofluorescent staining with a fluorescence microscope. The results showed that Baicalin exerted an inhibitive effect on CPE after influenza A H1N1 virus infection. The FACS with PI staining showed that the cell cycle of the infected cell was arrested at S phase, the Baicalin-treated group decreased S phase cell ratio and subG0 phase peak in comparison with the control (P < 0.05) and significantly promoted cell proliferation (# P < 0.05). Hoechst33258 staining suggested that Baicalin protected the cellular nucleolus against the influenza virus-induced apoptosis. Observation under the immunofluorescent microscope suggested that the activities of caspase-8 and caspase-3 were enhanced at 36 h post the influenza virus infection, but 100 microg/mL Baicalin suppressing the activation of caspase-8 and caspase-3 rather than that of caspase-9. In summary, this research confirmed that Baicalin inhibited the influenza A H1N1 virus strain infection in vitro, the drug obviously protected cells from apoptosis damages through regulating cell cycle and suppressed the activation of caspase-8 and caspase-3. The down-regulation was significant and showed a dose-dependent relationship.
