Objective:To synthesize the mental resilience of Chinese children tested with the Resilience Scale for Chinese Adolescents (RSCA)to evaluate its status as well as the research status. Methods:Four Chinese elec-tronic databases including China Biology Medicine disc (CBM),VIP Database,China National Knowledge Infra-structure (CNKI)and WangFang Database were searched from database established to December 2014. Literatures that reported the mental resilience status of Chinese children tested with RSCA were included. A statistical formula was used to synthesize means and standard deviations to get a total score;the standard mean difference (SMD)and 95% confidence interval (95%CI)of scores measured with RSCA scale were used to conduct meta-analyses usingthe software of Review Manager 5. 2 for comparison between different subgroups. Results:Thirty-nine studies with 16 493 children were included for the final analysis. Quantitative synthesis results showed that the average total score of Chinese children was (3. 3 0. 6 ). The status of psychological resilience was at a good level. The average psychological resilience scores of girls,not left-behind children,urban children,Han children and not-only-child were higher than those of boys [SMD (95%CI):-0. 09 (-0. 14--0. 05 )],left-behind children [SMD (95%CI):-0. 37(-0. 56--0. 19)],rural children [SMD (95%CI):0. 26(0. 13 -0. 38)],minority children [SMD (95%CI):0. 12(0. 04-0. 21)]and only-children [SMD (95%CI):0. 30(0. 16-0. 44)]respectively. Conclusion:The mental resilience of Chinese children is modest with internal diversity.

Objective To evaluate the influence of epimeric glycyrrhizic acid on production of endothelin-1 (ET-1) in the lungs induced by ischemia-reperfusion(I/R) injury.Methods Twenty healthy long-ear white rabbits of both sexes, weighing 1.1-2.1kg were randomly divided into 2 groups: group I I/R alone ( n = 10) and group II I/R + epimeric glycyrrhizic acid (n = 10). The animals were anesthetized with thiopental 25 mg?kg-1 and tracheotomized and mechanically ventilated (FiO2 = 100% , VT = 10-13 ml?kg, RR = 20-30 bpm, I:E= 1: 1.2). Anesthesia was maintained with fentanyl, thiopental and vecuronium. Femoral artery was cannulated for continuous direct BP monitoring. MAP was maintained at 70-90 mm Hg during experiment. Right interval jugular vein was cannulated. Catheter was inserted into right atrium for fluid administration, blood sampling and right atrial pressure monitoring. Chest was opened and the hilum of right lung was mass-ligated to induce ischemia for 60 min and then released for reperfusion for 60 min. Epimeric glycyrrhizic acid 30 mg?kg-1 was given iv 30 min before ischemia of the right lung. Blood samples were taken from right atrium and femoral artery for determination of ET-1 concentration before ischemia of right lung (T0) and 1 and 5 min after right lung started being perfused (T1 , T2). At the end of 60 min reperfusion of the right lung, the animals were sacrificed and lungs (right and left) were removed for electron microscopic examination. Results In group 1 at T, the ET-1 levels in the blood from both femoral artery and right atrium were significantly higher than the baseline (T0) and the ET-1 concentration in the blood from femoral artery was significantly higher than that from right atrium. In group II there was no significant difference in blood ET-1 concentration between T0 and T, .Conclusion Ischemia-reperfusion induces increased production of ET-1 in the injured lung. Epimeric glycyrrhizic acid can inhibit the increase in the production of ET-1 in the induced by I/R.

OBJECTIVETo explore the inhibition and molecular mechanism of icaritin (ICT) combined doxorubicin (DOX) on human osteosarcoma MG-63 cells in vitro.
METHODSThe control group, ICT groups (10, 20, 40, 80, and 160 µmol/L), DOX groups (1, 2, 4, 8, and 16 µg/mL), and combination groups (20 µmol/ L ICT +1 µg/mL DOX, 20 µmol/L ICT +2 µg/mL DOX, 20 µmol/L ICT +4 µg/mL DOX, 40 µmol/L ICT +1 µg/mL DOX, 40 µmol/L ICT +2 µg/mL DOX, 40 µmol/L ICT +4 µg/mL DOX, 80 µmol/L ICT +1 µg/mL DOX, 80 µmol/L ICT +2 µg/mL DOX, 80 µmol/L ICT +4 µg/mL DOX) were set up. Human osteosarcoma MG-63 cells were respectively cultured and their effects on morphological changes were observed using inverted phase contrast microscope after 24-and 48-h intervention. The cell proliferation inhibition rate of each group was de- termined using CCK-8, and IC50 calculated. The MG-63 apoptosis rate was detected using Annexin V-FITC/ PI double dye flow cytometry. Expression levels of bcl-2, caspase-3, and p21 were detected using RT-PCR.
RESULTSICT and DOX could obviously inhibit the proliferation of MG-63 cell. Along with ICT concentration increasing from 10 µmol/L to 160 µmol/L, the cell proliferation inhibition rate also increased gradually from 9.67% ± 3.62% to 89.18% ± 9.66%. The IC50 was 46.93 µmol/L and 3.87 µg/mL respectively. ICT and DOX could cause either early or late stage apoptosis, down-regulate Bcl-2 gene expression, and up-regulate gene expressions of Caspase-3 and p21 respectively (P < 0.05). Aforesaid changes were more obviously seen in combination groups than in lCT groups and DOX groups (P < 0.05).
CONCLUSIONCT combined DOX had additive or synergistic inhibition effect for the proliferation of osteosarcoma MG-63 cells, which might be related with regulating gene expressions of bcl-2, caspase-3, and p21.
