Objectives Research into effect on PBL model in prosthodontics education.Methods The PBL model was performed in education of a part of prosthodontics,and education effect was evaluated by table analysis.Results PBL model is proved to be better than the multimedia education model in the training of students'self-study ability,learning initiative,problem-analyzing and problem-solving competence,and the team spirit etc.Conclution Comparaed with the multimedia education model,PBL model is of significance in some respects.
2.An analysis on influencing factors of elders' medical consumption behavior under the back-ground of pension combined with medical service:A case study of Nanjing
Chinese Journal of Health Policy 2017;10(1):52-57
Objective: Under the background of pension combined with medical service, for the elders to reasonably, effectively and fully utilize the medical resources, it is of vital significance to establish good medical con-sumptive behavior and consumption intention, to promote healthy old age and improve elders' health and happiness to help them cultivate a fine habit in their practical life. Methods: Based on the micro-survey data of investigation in Nanjing, this paper systematically analyzed the factors influencing elders' medical consumption behavior by using the theory of planned behavior and structural equation model. Results:Different factors were classified into behavioral at-titudes, subjective norms and perceived behavior control, and significant variables were found out through behavior model as well as though measuring their relative effects. Conclusion: There is no significant casual relationship be-tween the perceived behavior control and medical consumption behavioral intention. The elders' medical consumption behavior intention is affected by various social network relationships. The belief strength, normative belief, behavioral attitudes and subject norms can affect elders' medical consumption behavior.

Tuberculosis (TB) remains an enormous health burden worldwide.To date,Mycobacterium bovis Bacillus Calmette Guerin (BCG) is the unique anti-TB vaccine available for humans,which provides an important but limited protection from the Mycobacterium tuberculosis (Mtb) infection.It is therefore an urgent need to develop better vaccines and vaccination strategies to prevent the spread of Mtb infection.Heterologous prime-boost vaccination strategies using both BCG and novel anti-TB vaccines have been demonstrated to induce robust immune responses than BCG alone.We have previously demonstrated that a recombinant adenoviral vector Ad5-CEAB co-expressing CFP10,ESAT6,Ag85A and Ag85B of Mtb was able to induce robust antigen-specific immune responses in mice.In the present study,we examined immunological effects of Ad5-CEAB in the mice primed with BCG and boosted with a single dose of the virus via an intranasal route.Results demonstrated that this vaccination strategy could effectively induce strong antigen-specific mucosal and humoral immune responses.These immune responses were characterized with an increased productions of cytokines (IL-12 and IFN-γ),increased concentration of secretary IgA (sIgA) in bronchoalveolar lavage fluid (BALF) and serum IgG in mice in comparison with mice in BCG group.These data suggested that the regimen of BCG prime-single dose of Ad5-CEAB boosted strategy was novel for inducing antigen-specific immune responses in response to Mtb antigens in vivo,which warrants for further development of adenoviral-based vaccine against Mtb infection.

Based on formal concept analysis theory, formal context of formulae, herbs and their relationship was cre-ated in this article first. Then, the created formal context would be divided and optimized according to classification method in Shang Han Lun Lei Fang written by Xu Lingtai, such as Guizhi Tang category, Chaihu Tang category, Xiexin Tang category, and etc. Multilayer complex concept network was used in the description of the universality and particularity of things. The multilayer complex concept network figure of key-formula-classified formulae was completed on the subgroup structure and visualized express of formulae, herbs and their relationship in the Treatise on Exogenous Febrile Disease. This is a new attempt of integrated information technology with diseases harmed by cold in traditional Chinese medicine. It will bring great benefit in relearning traditional classification methods and promoting inheritance and innovation of study on the Treatise on Exogenous Febrile Disease.

OBJECTIVETo investigate the theoretical model of the three-dimensional structure of mosquitocidal Cry30Ca2 and its molecular docking with N-acetylgalactosamine.
METHODSThe theoretical model of Cry30Ca2 was predicted by homology modeling on the structure of the Cry4Ba. Docking studies were performed to investigate the interaction of Cry30Ca2 with N-acetylgalactosamine on the putative receptor.
RESULTSCry30Ca2 toxin is a rather compact molecule composed of three distinct domains and has approximate overall dimensions of 95 by 75 by 60Å. Domain II is a helix bundle, Domain II consists of three antiparallel β-sheets, Domain III is composed of two β-sheets that adopt a β-sandwich fold. Residue 321Ile in loop1, residues 342Gln 343Thr and 345Gln in loop2, residue 393Tyr in loop3 of Cry30Ca2 are responsible for the interactions with GalNAc via 7 hydrogen bonds, 6 of them were related to the oxygen atoms of hydroxyls of the ligand, and one to the nitrogen of the ligand.
CONCLUSIONThe 3D structure of Cry30Ca2 resembles the previously reported Cry toxin structures but shows still some distinctions. Several residues in the loops of the apex of domain II are responsible for the interactions with N-acetylgalactosamine.

Objective To investigate the effects of COMT G472A genetic polymorphism on postoperative analgesia with fentanyl.Methods One hundred and twenty-nine ASA I or Ⅱ patients aged 19-71 yr undergoing operation on lumbar vertebrae under general anesthesia were enrolled in this study.Polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) was used to detect the polymorphism of COMT G472A.The patients were assigned into 2 groups according to their genotypes:wild group and mutation group.Pain was assessed using VAS after the patients regained consciousness.When VAS score > 3,the patients were given fentanyl 20μg iv every 5 win until VAS score was decreased to ≤ 3.PCIA was then started.The PCIA solution contained fentanyl 20 μg/kg + flurbiprofenaxetil 150-250 mg or propacetamol 4-6 g in normal saline 75 ml.The patients received a background infusion of 1 ml/h after a loading dose of 3 ml.The PCIA pump was programmed to allow a 0.5 ml bolus with a 15 min lockout interval.The amount of fentan yl infused in 24 h and 48 h was recorded.The amount of flurbiprofen (1 mg=fentanyl 1 μg) or propacetamol (1 g =fentanyl 37.5 μg) was transformed into fentanyl.Results Significantly less fentanyl was consumed in 48 h in mutation group ( n =49) than in wild group ( n =80).Conclusion COMT G472A is a factor contributing to the individual variation in patient' s response to postoperative analgesia with fentanyl.
