Enterovirus 71 (EV71) is one of the primary causative agents of hand, foot and mouth disease in children and closely associated with severe neurological complications and even deaths.EV71 outbreaks have occurred throughout the Asia-Pacific region since 1990s, posing global public health threat;however, no specific therapeutic strategy exists for severe EV71 infection.Several inactivated vaccine products have entered or finished the clinical trial stage, and some novel vaccine candidates, including live attenuated, subunit, and virus-like particle, show great potential for further develop-ment.This review summarizes the present situation and progress in the development of EV71 vaccines.

OBJECTIVE: To investigate the regulating effects and its possible mechanism of safflower yellow (SY) on tau protein hyperphosphorylation in SH-SY 5Y cell induced by okadaic acid (OA). METHODS: Cell viability was measured by MTT colorimetric method. The cell apoptosis was determined with Hoechst 33342 after SH-SY 5Y cell were treated with SY. To determined the phos-phorylated tau protein of p-tau (T205), p-tau(S199) sites, and total GSK-3β, PP2A in SH-SY 5Y cell were determined using Western blotting. RESULTS: SY significantly increased survival rates of SH-SY5Y cell damaged by OA. Hoechst 33342 showed that SY decreased the apoptosis of SH-SY5Y cells. Western blotting analysis showed that tau protein content was increased compared to control group at p-tau (T205), p-tau (S199) sites. However, SY treatment significantly reduced tau protein content at p-tau (T205) and p-tau (S199) sites. PP2A content was significantly suppressed by OA, significantly increased by SY, GSK-3β content was significantly increased by OA and significantly decreased by SY. CONCLUSION: These results suggest that safflower yellow may have neuroprotective effect on OA-induced SH-SY 5Y cells injury, which may be associated with tau hyperphosphorylation at the enzyme level by activation of tau kinases or by a decline in the activities of tau phosphatases.

To evaluate the clinical curative effect of Compound Biejia Ruangan Tablets (CBRT) combined with Adefovir Dipivoxil in the treatment of chronic hepatitis B with liver fibrosis using Meta-analysis. Cochrane library, PubMed, CNKI, Wanfang databases, and VIP were retrieved comprehensively to collect randomized controlled trials (RCTs) of CBRT combined with Adefovir Dipivoxil in the treatment of chronic hepatitis B with hepatic fibrosis from their inception to October 2017. treatment group was treated with CBRT combined with Adefovir Dipivoxil, and the control group was treated with Adefovir Dipivoxil. All the data were analyzed using Revman 5.3. A total of 19 RCTs and 1 776 patients were included. Meta-analysis results showed that the serum indexes including HA, IV-C, LN, PCIII, ALT, AST, and TBIL of the treatment group, were significantly lower than those of control group. HA [SMD = -1.72, 95% CI (-2.26, -1.17), P = 0.000 01]; IV-C [SMD = -1.10, 95% CI (-1.66, -0.54), P = 0.000 10]; LN [SMD = -1.18, 95% CI (-1.64, -0.73), P = 0.000 01]; PCIII [SMD = -1.52, 95% CI (-1.97, -1.07), P = 0.000 01]; ALT [SMD =-0.48, 95% CI (-0.68, -0.28), P = 0.000 01]; AST [SMD = -1.19, 95% CI (-2.08, -0.29), P = 0.010 00]; TBIL [SMD = -0.98, 95%CI (-1.38, -0.58), P = 0.000 01]; There were no significant difference in serum HBV DNA, and HbeAg negative conversion rate treatment group compared with control group. HBV DNA [RR = 1.21, 95% CI (0.97, 1.50), P = 0.09]; HBeAg [RR = 1.05, 95% CI (0.82, 1.34), P = 0.70]; The total clinical effective treatment group was significantly better than control group. [RR = 1.25, 95% CI (1.15, 1.36), P = 0.000 01]. Compared with the single use of Adefovir Dipivoxil, the clinical curative effect of CBRT combined with Adefovir Dipivoxil in the treatment of chronic hepatitis B with liver fibrosis is better,which can significantly reduce the level of serum liver fiber markers and improve liver function in patients with biochemical indicators and the total clinical efficiency.

Objective: To determine if the hemagglutinin A (HagA) of Porphyromonas gingivalis could be involved in the adhesion and invasion in human gingival epithelial cells (HGEC). Methods:P. gingivalis 381 hagA mutant was constructed by conjugation method. The whole length of hagA gene was cloned into pYA292 in Salmonella typhimurium x4072 (S. typhimurium-hagA). The strains were used to test their ability of adhesion and invasion into HGEC using a standard antibiotic protection assay. S. typhimurium x4072 strains containing empty vectors were used as negative control. HagA expression in S. typhimurium-hagA was confirmed by Western blot. Results:Although there were no significant differences between P. gingivalis 381 hagA mutant and wild type in adhesion and invasion into HGEC, the adhesion values of S. typhimurium-hagA to HGEC were increased by 3 times compared to their respective controls, while the invasion ability of S. typhimurium-hagA was 4 times greater than that of the negative controls. Conclusion: These results suggest that HagA may participate in P. gingivalis adhesion and invasion into HGEC.
