Objective:To explore the change of the behaviour, cognition and emotion of the public in Beijing during different prevalence of SARS Method: "Questionnaire on SARS" was designed by authors Through e-mails or websites, 473 valid copies were collected in Beijing Result:Facing with SARS, the public in Beijing faced high pressure from the environment They concerned with the information on SARS very much, and adopted more self-protection behaviours, such as wearing masks, paying more attention on personal hygiene Some people also showed irrational behaviours, such as storing cashes and food, taking the temperature too much times within one day and so on As for the cognition, people thought they should adjust themselves psychologically in order to overcome SARS related problems without being panic When the SARS cases increasing, physical and psychological stricture made people feel more nervous, panic, helpless, angry and pessimistic, as well as less excited, calm and numb The cognition, behaviour and the emotion of Beijing's public varied along with the situation in Beijing and in China

BACKGROUND:Someone regards that treatments such as root canal therapy and post-core restoration can increase the fracture probability of teeth. Can fiber reinforced composite post enhance the fracture resistance of the severe wedge-shaped defected premolar? Three-dimensional finite element can simplify complex dental systems into a model analyzed by computer, and conduct biomechanical research through the model analysis. OBJECTIVE:To analyze the stress distribution of sever wedge-shaped defected first premolar which restored by fiber reinforced composite post and composite resin. METHODS:We established the three-dimensional finite element models of severe wedge-shaped defected maxil ary first premolar before and after restoration with fiber reinforced composite post and composite resin. The maximum bite force was designed to 267 N that was applied at 45° angle. Then, we analyzed the distribution of maximum principal stress in finite element models. RESULTS AND CONCLUSION:The maximum principal stress was concentrated in the tip of defected region. After restoration, the distribution of maximum principal stress was similar to that of the normal premolar, and the tensile stress was distributed uniformly in the upper-central part of buccal root. It may be beneficial for improving fracture resistance ability of severe wedge-shaped-defect premolar by restoration with fiber reinforced composite post and composite resin.

Objective To explore the curative effect of modified closed negative pressure drainage on abnormal abdominal incision. Methods Sity-three patients with abnormal healing of abdominal incision in our hospital from January 2012 to June 2013 were selected as the observation group. Another 50 patients from January to December 2011 were assigned to the control group. The former was treated after debridement with human recombinant surface growth factor and modified closed negative pressure drainage,while the latter after debridement with anti-infection and dressings of ethacridine or gentamicinsolution as well as with infrared therapy. The two groups were compared in terms of the frequency,time and cost of changed dressings,and the healing time of the incisions.Results There was insignificant difference in the cost of changed dressings between the two groups(P>0.05). However,the differences were statistically significant in terms of the frequency and time of changed dressings and the healing time of the incisions(P<0.05). The observation group was significantly superior to the control group.Conclusions Modified closed negative pressure drainage is effective in accelerating the healing in abnormal abdominal incisions,reducing the frequency and the time of changed dressings,and easing the economic burdens of the patients,which is suggested to be popularized and applicable in the pimary hospitals.
