Objective:To explore novel compounds with anti-EV71 activity. Methods: A series of oligopeptides were designed based on the active groove of the EV71 3C protease using molecular simulation technology. Furthermore, some oligopeptides were syn-thesized and tested for the inhibition ability against EV71 in vitro. Results:Pentapeptides had higher binding affinity to the EV71 3C protease than the other oligopeptides, such as compounds 25 and 16. Therefore, compounds 25 and 16 were synthesized and tested in vitro for the anti-EV71 activity, and compound 25 exhibited potent anti-EV71 activity(EC50 =1. 36 μmol·L-1, CC50 =211. 94 μmol ·L-1, SI=155. 84), while compound 16 had no evident effect on EV71. Conclusion: It is worthy of further investigation on com-pound 25 as a novel scaffold of anti-EV71inhibitor.

Objective:The study is to compare the prevalence and related factors of suicidal ideation in ado-lescents between China and Philippine.Methods:Our research data was downloaded from the website of world health organization (WHO).It was the data of China and Philippine from the Global school-based student health survey(GSHS)which was launched by the WHO,and 9173 students in China and 7338 students in Philippine aged 11 -16 years were involved.The situations of being serious injury,being bullied,sense of loneliness,insomnia, sense of hopelessness,friends,smoking,alcohol consumption,drug abuse and exercise were assessed by the ques-tionnaire.The definition of suicidal ideation was that ever thinking of suicide seriously in the last 12 months.Results:The rate of having suicidal ideation in China and Philippine were 17.4% (1544 /8881 )and 19.3% (1371 /7089),respectively.Multivariate analysis showed that female (OR =1.45),grade two and three of middle school (OR =1.29,1.43),being serious injury (OR =1.35),being bullied (OR =1.87),sense of loneliness (OR =1.47),insomnia (OR =1.55),sense of hopelessness (OR =3.36),alcohol consumption (OR =1.45)and drug abuse (OR =1.55)were the risk factors to suicidal ideation in China adolescents,and having good friends (OR=0.66)and exercise regularly (OR =0.78)were the protective factors.However,the female,grade,sense of lone-liness,insomnia and drug abuse were not the risk factors to suicidal ideation in Philippine adolescents,and other fac-tors were similar to China sample.Conclusion:There may be differences in the prevalence rate of suicidal ideation between adolescents in China and Philippine,with lower rate in China.Meanwhile,there are similarities in the relat-ed factors on the adolescent suicidal ideation of the two countries,with more risk factors in China sample.Therefore,the individualized targeted measures should be taken to prevent suicide in China and Philippine respectively.

This systematic review was aimed to evaluation the effectiveness and safety of supplementingqi and activating blood circulation prescriptions in the treatment of cerebral ischemic stroke. Dtabases both at home and abroad were electronically searched for randomized controlled trials (RCTs) on supplementingqi and activating blood circulation prescriptions in the treatment of cerebral ischemic stroke. And meta-analyses were performed using RevMan 5.0 software. The results showed that 27 studies were included, which contained 2 908 cases. There were 1 490 cases in the treatment group, and 1 418 cases in the control group. The results of meta-analyses indicated that supplementingqi and activating blood circulation prescriptions combined with routine treatment of modern medicine had significant differences in the effective rate for cerebral ischemic stroke compared with the single using of routine treatment of modern medicine with significant difference (OR = 5.39, 95%CI (4.03, 7.22),P < 0.000 01). The treatment of supplementingqi and activating blood circulation prescriptions combined with routine treatment of modern medicine had better treatment effect on neurological function defects for cerebral ischemic stroke compared with the single using of routine treatment of modern medicine with significant difference (WMD = -2.99, 95%CI (-3.26, -2.72),P < 0.000 01). In addition, the treatment of supplementingqi and activating blood circulation prescriptions combined with routine treatment of modern medicine had better treatment effect on improving the activity of daily living (WMD = 9.65, 95%CI (8.36, 10.93),P < 0.000 01). Adverse reaction and event was mild in 2 included research reports. It was concluded that the treatment of supplementingqi and activating blood circulation prescription or it combined with routine treatment in modern medicine was quite effective in the treatment of cerebral ischemic stroke by the existed limited evidences. It can also improve the nerve dysfunction and the ability of daily living. Due to the limited quantity of the included studies and the evidence with limited strength, further high-quality RCTs were needed to verify the forementioned conclusion.

Objective To explore the effect of electroacupuncture intervention on tumor growth and PCNA expression in HepG2 nude mice.Methods Thirty-two nude mice were randomized to electroacupuncture, electrostimulation, model and blank control groups, 8 mice each. A nude mouse model of subcutaneous tumor was made with HepG2. The electroacupuncture group received electroacupuncture at points Zusanli and Sanyinjiao on bilateral lower limbs and the electrostimulation group, direct electrical stimulation of the same points. The tumor volume, the tumor/weight ratio and the tumor growth inhibition rate were observed. PCNA expression in the tumor tissue was determined.Results There was no statistically significant pre-/post-intervention difference in the tumor volume in the electroacupuncture, electrostimulation and model groups (P>0.05). There was no statistically significant post-intervention difference in the tumor volume between the electroacupuncture or electrostimulation group and the model group (P>0.05), but tumor growth tended to slow in the electroacupuncture group. There was no statistically significant pre-/post-intervention difference in the nude mouse weight in every group (P>0.05). There was a statistically significant post-intervention difference in the tumor/weight ratio between the electroacupuncture group and the electrostimulation or model group (P<0.05), but no statistically significant post-intervention difference in the tumor/weight ratio between the electrostimulation and model groups (P>0.05). There was a statistically significantpost-intervention difference in the tumor growth inhibition rate between the electroacupuncture and electrostimulation groups (P<0.05). There was a statistically significant post-intervention difference in the PCNA expression level between the electroacupuncture or electrostimulation group and the model group (P<0.05), no statistically significant post-intervention difference in the PCNA expression level between the electroacupuncture and electrostimulation groups (P>0.05).Conclusion Electroacupuncture can delay HepG2 tumor growth to a certain extent.

Recombinant Fl-V (rFl-V) fusion protein is the main ingredient of the current candidate vaccine against Yersinia pestis infection, which has been under investigation in clinical trial in USA. We investigated the soluble expression conditions of rF1-V in Escherichia coli BL21 (DE3) that we constructed before. After scale-up and optimization of fermentation processes, we got the optimized fermentation process parameters: the culture was induced at the middle exponential phase with 50 µmol/L of IPTG at 25 °C for 5 h. Soluble rFl-V protein was isolated to 99% purity by ammonium sulfate precipitation, ion exchange chromatography, hydrophobic chromatography and gel filter chromatography. The protein recovery was above 20%. Protein identity and primary structure were verified by mass spectrometry and Edman sequencing. Results of purity, quality and western blotting analysis indicated that the target protein is a consistent and properly folded product. Furthermore, the immunogenicity of various antigens formulated with aluminum hydroxide adjuvant was evaluated in mice. Serum antibody titers of 4 groups including 20 µg rFl, rV and rFl-V and 10 µg rFl+10 µg rV, were assayed by ELISA after 2 doses. The antibody titers of anti-Fl with 20 µg rFl-V were obviously higher than titers with other groups; meanwhile there were no significant difference of anti-V antibody titers among them. These findings confirm that rFl-V would be the active pharmaceutical ingredient of the plague subunit vaccine.
