DOI:10.3969/j.issn.2095-1396.2022.02.004 Abstract（ 16） PDF（1368KB）（ 2） Objective：To investigate the effect of Peony licorice decoction extract （SYG） on oxidative stress and inflammatory response induced by hydrogen peroxide （H 2O 2） on myocardial cells. Methods：Myocardial cells were divided into five groups，respectively normal group，model group （200 μmol·L -1H 2 O 2） and SYG groups （150，100，50 μg·mL -1），and after the intervention of Peony licorice decoction for 24 h，H 2 O 2was treated for 2 h，then MTT method was used to detect cell proliferation ability，determination of superoxide dismutase （SOD），catalase （CAT），lactate dehydrogenase （LDH） and malondialdehyde （MDA） by UV spectrophotometry. RT-PCR was used to evaluate the inflammatory factor tumor necrosis factor-α（ TNF-α），inducible nitric oxide synthase （iNOS），cyclooxygenase-2 （COX-2），and nuclear factor kappa-B （NF-κB）in myocardial cells. Results：H 2 O 2induction could significantly reduce the contents of SOD and CAT，and significantly increase the contents of MDA and LDH，while SYG could significantly improve the above phenomena，and SYG could inhibit the expression of TNF-α，iNOS，COX- 2 and NF-κB. Conclusion：SYG can inhibit the oxidative stress and inflammatory response of myocardial cells induced by H 2 O 2，and has a certain protective effect on myocardial ischemia.

DOI:10.3969/j.issn.2095-1396.2022.02.001 Abstract（ 8） PDF（4258KB）（ 1） Objective：To establish an in vitro oxygen glucose deprivation/reoxygenation （OGD/R） model using SH-SY5Y neuroblastoma cells to mimic the in vitro ischemia/reperfusion injury in stroke. To evaluate the potential neuroprotective effect of S14G-humanin （HNG） from ischemia/reperfusion in vitro，and further to identify the molecular mechanism underlying the protection，so as to provide a theoretical basis for the treatment of cerebral ischemia/reperfusion injury with HNG. Methods：SH-SY5Y cells were divided into control group，oxygen-glucose deprivation reperfusion OGD/R model group and inhibitor group. The present study established an in vitro OGD/R model using SH-SY5Y neuroblastoma cells by three gas incubator. HNG and FLLL32，an inhibitor of JAK2/STAT3 signal，were added to the cells in indicated experiments. CCK8 kit was used to detect the cell viability，and flow cytometry was used to detect the cell apoptosis rate. The expression of JAK2，p-STAT3（Y705） and p-STAT3（S727） were analyzed by Western Blot. Results：The results showed that OGD/R resulted in a significant decrease in the survival rate of SH-SY5Y cells （P<0.01） and a significant increase in the apoptosis rate of SH-SY5Y cells （ P<0.01）. SH-SY5Y cells incubated 0.1，1，5 or 10 μg·L -1HNG showed higher cell survival （ P<0.01） and significantly decreased apoptosis （ P<0.01） compared with the cells without HNG treatment in OGD/R processes，with the most evident effects at 1 μg·L -1HNG. OGD/R lowered protein levels of JAK2 （ P<0.01） and p-STAT3 at Y705 site （ P<0.01），compared to control. Adding HNG to the cells increased protein levels of JAK2 （ P<0.01） and p-STAT3 （Y705）（ P<0.01） in OGD/R conditions. Moreover，protein levels of JAK2（ P<0.01），p-STAT3 （Y705）（ P<0.01） and p-STAT3（ S727）（ P<0.05） had notable increase at values of 1 and 5 μg·L -1HNG in OGD/R conditions. Co-treatment with HNG and FLLL32 was unable to restore the cell viability and abolishing the inhibition of apoptosis by HNG（ P>0.05）. HNG inhibited OGD/ R-induced reduction of JAK2，p-STAT3（Y705） and p-STAT3（S727） protein expression， whereas the inhibitory effect was not observed with co-treatment with HNG and FLLL32. Conclusion：These data collectively indicate that HNG has neuroprotective effects against OGD/ R by activating JAK2/STAT3 signaling and suggest that HNG may be a promising drug for the treatment of stroke.
