To explore novel monoamine reuptake inhibitor with antidepressant activity, a series of substituted aryl alkanol piperidine derivatives were designed and synthesized. All of them were new compounds, and their structures were confirmed with 1H NMR and HR-MS. The results showed that compounds 4, 5 and 8 displayed strong 5-HT, NA and DA reuptake inhibiting activities in vitro. Among the tested compounds, 4, 5 and 13 exhibited potent antidepressant activities in the mice forced swimming test. Compounds 4 and 5 have potent antidepressant activities and are worth further development.

Objective:To evaluate the effects of the flowable resin used as pit and fissure sealant using different etching adhesive systems.Methods:60 caries-free extracted human premolars were randomly divided into 4 groups(n =1 5)and treated by Gluma, NT and 3M-Z350 flowable resin(group A);Clearifil SE Bond adhesive and 3M-Z350 flowable resin(group B),phosphoric acid etching,3M-Z350 flowable resin and phosphoric acid etching(group C)and 3Mconcise sealant(group D)respectively.After pro-cessing the tooth surface the pit and fissue of 1 0 sample in each group were sealed.The microleakage was measured by 1 % methyl-ene blue staining(n =8).The material-enamel interface was observed by SEM(n =2).The shear bond strength of the column-shaped samples with the diameter and the height of 3 mm(n =5)on the mesial or dental surface was examined by a test machine. The sealant cartridges and flowable resin cartridges with the diameter and height of 4 mm were used for the crushing strength exami-nation(n =1 0).Results:There was no significant difference in the microleakage among the 4 groups.SEMobservation showed that the resin tags of group A were long and dense and the resin tags of group B were short and sparse,bubbles and cracks were found on the local site in group A and B.The resin tags of group C were long and thin,but combined with tooth tightly;the resin tags of group D were short and dense;the penetration was poor at the bottom of the fissures in the 4 groups.The shear bond strength of Group A was the highest(P <0.01 ),that of group C was higher than that of group B and D(P <0.05).There was no significantly difference between group B and D(P >0.05).The compressive strength of flowable resin groups was higher than that of fissure seal-ant group(P <0.05).Conclusion:The shear bond strength and compressive strength of all-etching bonding system combined with flowable resin is superior to that of self-etching bonding system combined with flowable resin and the traditional sealant.Using Prime&Bond NT bond after acid etching may improve the shear bonding strength.

Objective To investigate the brain metabolic changes and evaluate their spatial distributions after traumatic axonal injury (TAI)in rats by using proton magnetic resonance spectroscopy(1H-MRS).Methods The TAI model was made by subjecting the head of the rats to the linear and angular accelerations.The multi-voxel MRS was employed to detect the tissue metabolic state at the levels of hippocampus-caudate and pons prior to injury and at 24 hours after injury.The alterations of NAA/Cr,NAA/Cho and Cho/Cr values as well as the spatial distribution of NAA/Cr reduction were accessed. Immunohistochemical staining for β-APP was used to observe the injured axons. Results A siguificantdecrease in NAA/Cr and NAA/Cho(P<0.05)and subtle increase in Cho/Cr(P>0.05)were observed in rats at 24 hours after TAI in comparison to the pre-injury levels.Notable decrease in NAA/Cr value was observed in the areas including the brain stem,hippocampus,internal capsule,corpus callosum and thalamus,where axonal injuries were confirmed by the histological examination. Conclusion Metabolic imbalances Occur in the brains of rats with TAI.with notable changes in the brain stem and the hippocampus.

Objective: To explore the clinical and anatomical characteristics of coronary slow lfow (CSF) in relevant patients.
Methods: We summarized the patients without coronary angiography (CAG) proved coronary stenosis (stenosis < 40%) while with TIMI indicated CSF in our hospital from 2013-01 to 2015-01. The patients were divided into 2 groups: CSF group, n=56 patients having at least 1 major coronary artery with TIMI frame counts > 27 and Control group,n=55 patients with normal coronary lfow. The related laboratory indexes were examined and relationship between MCV and CSF was studied by multi-logistic regression analysis.
Results: In CSF group, MCV 90.4 (87.48, 92.65) fL and RDW-CV 12.5 (12.30, 13.18) % were lower than those in Control group 92.3 (90.1, 94.3) fL and 13(12.7, 13.4) %,P<0.05; while MCHC 337 (332, 347) g/L and the number of left circumlfex distal braches involved 3 (2, 4) were higher than those in Control group 327.5 (322, 338) g/L and 2 (2, 3),P<0.05. Multi-logistic regression analysis showed that MCV was negatively related to CSF (partial regression coefficient= -0.138, P=0.015), Spearman rank correlation analysis presented that MCV was negatively related to TIMI frame counts (r= -0.201, P=0.009).
Conclusion: Deformability of red blood cells might be involved in pathogenesis of CSF in relevant patients.
