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.

BACKGROUND: 6-minute walking test (6MWT) is a submaximal test, characterizing by easily processing and low cost, thus it is widely used in the clinic. However, how to change walking distance into maximal motor capacity needs to be further studied.OBJECTIVE: To study the correlation of 6-minute walking distance (D), work (W), peak oxygen uptake (VO_2 peak) and maximal oxygen uptake (VO_2 max) detected by Bruce.DESIGN, TIME AND SETTING: This study was performed at tshe Department of Rehabilitation Medicine, Zhongda Hospital affiliated to Southeast University from March to May 2009.PARTICIPANTS: A total of 25 healthy volunteers were enrolled, including 14 males and 11 females, with a mean age of (22.0±2.3) years.METHODS: All 25 subjects were tested with cardiopulmonary exercise testing (CPET) according to Bruce, VO_2 max and anaerobic threshold (AT) was detected respectively, then 6MWT" was adopted to detect 6-minute walking distance (D), work (W) and maximal oxygen uptake (VO_2 max) of subjects. Data of pulmonary gas exchange in breathing was detected by wireless remote sensor K4b~2 to obtain VO_2 max and VO_2 peak.MAIN OUTCOME MEASURES: ① Regularity of cardiac rate, oxygen uptake and respiratory frequency varied with time passing; ② Walking distance, work, oxygen uptake, cardiac rate and respiratory frequency were compared before and after testing; ③ Maximal oxygen uptake and anaerobic threshold with CPET were compared to peal oxygen uptake with 6MWT; ④ Correlation of distance, work between maximal oxygen uptake and peal oxygen uptake.RESULTS: There was no significant difference between AT from CPET and VO2 peak from 6MWT (P > 0.05). 6-minute walking distance was not correlated with either VO_2 peak or VO_2 max. However, 6-minute walking work was linearly correlated with both VO2 peak (r=0.779 7, P < 0.001) and VO_2 max (r=0.894 1, P < 0.001).CONCLUSION: 6-minute walking test is an exercise test at level of anaerobic threshold. 6-minute walking work can reflect both submaximal exercise capacity and maximal exercise capacity.

The case of a 49-years-old man complained of pharyngalgia for one year and shortness of breath after activities for one week. Endoscopic laryngeal examination and computed tomography revealed a supraglottic mass. Direct laryngoscopy was performed and biopsy of the mass was carried out. Results of the histopathologic examination and immunohistochemical analysis were consistent with atypical carcinoid tumor of the larynx.

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.
