In order to adapt to the development of society,an innovative talent cultivation system has been explored to train stomatological specialists with active innovation spirit and strong ability to practise.

It is the objective of this study to develop dynamic predictive model for the extraction process of red Ginseng using NIR spectroscopy. NIR spectroscopy was collected online and PLSR models were developed for total quantity of ginsenosides. The performance of NIR prediction model achieved R, RMSEC, RMSEP of 0.996 09, 0.018 9, 0.016 8, respectively. A first order dynamic mass transfer model was combined with NIR prediction of the quality indicator to predict the trajectory of the extraction process based upon the initial 3 or 4 data points. The results showed good agreement with actual measurements indicating reasonable accuracy of the predictive model. It could potentially be used for advanced predictive control of the extraction process.

Objective To compare the effects of vitrification with slow-freezing on the developmental ability of day 3 cleavage stage embryos.Methods Patients who had no less than 4 high quality embryos were included in this study.These embryos were cryopreserved using the methods of vitrification or slow-freezing.In the eryopreserved embryo transfer cycles,the embryos which were cryopreserved using one of the methods were chosen randomly.The developmental ability of embryos was compared between these two groups.Results A total of 80 patients were included in this study with 160 embryos.In the group of slow-freezing,73(91%)embryos were survived and achieved 15(38%)clinical pregnancies.Among these,3 were twins and the implantation rate was 25%(18/73).In the group of vitrification,71(89%)embryos were survived and achieved 19(48%)clinical pregnancies.Among these, 9 were twins and the implantation rate was 39%(28/71),which was significantly higher than the slow- freezing group(P

Objective To study the relationship between the intervals of Mitomycin C treatment and cytotoxicity, apoptosis and drug resistance for bladder cancer cells.Methods The bladder transitional cell cancer line BIU-87 was treated for two hours every time for five times with intervals of 24, 48, 72 and 96 hours respectively.Cytotoxicity was measured by MTT.p53,bcl-2,Bax and p170 expression were analyzed by Western blot.Results The IC_(50)(?g/ml)were 4.41,0.71,2.83,4.51and 6.16 with treatment intervals of 24, 48, 72 and 96 hours respectively, p53 and bcl-2 were significantly down-regulated and bcl-2/Bax was re- duced at 24 hour treatment interval but not changed at 48,72 and 96 hour intervals,p170 was not detected at 24 hour treatment interval but increasingly expressed at 48,72 and 96 hours intervals.Conclusion The in- terval of Mitomycin C treatment is closely related with cytotoxieity and apoptosis and drug resistance of blad- der cancer cells.The intervals of intravesical instillations may play an important role in the effect of chemotherapy.

OBJECTIVETo analyze the energy relieving effect of different thickness of mucosa beneath mandibular complete denture and try to analyze clinical question of prosthodontics using energy analysis methods.

METHODSA 3-DFE model of the mandibular complete denture and its supporting tissue were set up. Their elastic deformed energy and the percentage in the whole system were respectively calculated when mucosal thickness was different.

RESULTSThe percentage of mucosal elastic deformed energy grew from 44.53% to 52.91% and 57.91% with its different thickness under static loads.

CONCLUSIONSThe energy relieving effect of mucosa grows with its thickness and the approach of energy analysis is one of effective method on oral biomechanics questions.

OBJECTIVETo explore in vivo metabolic changes in abnormal savda patients with different types of tumor.

METHODSA total of 142 abnormal savda patients with common cancer types were enrolled in this study, and 50 healthy volunteers were recruited as the control group. For each sample, the H Nuclear Magnetic Resonance (NMR) based metabonomic analysis was performed. The free attenuation signal was computed subsection integral. Data obtained were analyzed by the Orthogonal Partial Least-Squares Discriminant Analysis (OPLS-DA).

RESULTSCompared with the control group, leucine, isoleucine, valine, histidine, phenylalanine, tyrosine, alanine, creatine, lactic acid, inositol, alpha-and beta-glucose, unsaturated lipids, very low density lipoprotein (VLDL) significantly decreased (P <0.05), while glycoprotein and carnitine significantly increased (P <0. 05) in the abnormal Savda group.

CONCLUSIONAbnormal savda patients with different types of tumor had similar metabonomics changes.

AIM:To investigate the synergistic anti-proliferation effect of aspirin and 5-fluorouracil on the co-lon cancer cells and its mechanism .METHODS: Colon cancer cells were divided into 4 groups: control group , aspirin group, 5-fluorouracil group and aspirin +5-fluorouracil group .Synergistic anti-proliferation effect of aspirin and 5-fluoroura-cil on the colon cancer cells was observed by MTT assay .Apoptosis-inducing effect and mechanism were detected by Hoechst 33258 staining, caspase activity assay and flow cytometry analysis .The mRNA and protein levels of apoptosis-re-lated proteins were evaluated by real-time PCR and Western blotting .RESULTS:5-Fluorouracil inhibited proliferation of HCT116 and SW620 colon cancer cells effectively , and low concentration of aspirin exerted synergistic inhibitory effect .5-Fluorouracil induced apoptotic morphology and increased caspase activity and sub -G1 phase in HCT116 cells.The synergis-tic effect of aspirin obviously enhanced apoptotic ratio and caspase activity .Moreover , 5-fluorouracil inhibited the mRNA and protein expression of Bcl-2, which was amplified by low concentration of aspirin .CONCLUSION:Aspirin and 5-flu-orouracil had a synergistic anti-proliferation effect on the colon cancer cells through apoptosis pathway .

Objective To study the risk factors in patients with trauma accompanied by multiple organ dysfunction syndrome.Method The data of 107 patients with trauma in ICU,Tongji Hospital,Tongji Medical College,Huazhong University of Science and Technology,were retrospectively studied.All patients were divided into 2 groups:MODS group and non-MODS group.The clinical and laboratory,results,ISS score,APACHEⅢscore and GCS score were studied.Results There were no differences on gender,age and mobility of shock between the two groups.There were significant differences on the treatment of shock,ISS score,APACHEⅢscore,CCS score,the levels of blood sugar and platelet between two groups.The Logistic regression analysis showed the main risk factors were treatment of shock,ISS score and APACHEⅢscore.Conclusions The risk factors in patients with trauma accompanied by multiple organ dysfunction syndrome were the treatment of shock, ISS score and APACHEⅢscore.
