BACKGROUND:Molars are characterized by multi-root, multi-root canal, multi-directional, different geometric shape and distribution. Single-root canal teeth post-core theory was used to guide molar repair in the clinic. It is easy to cause root canal perforation or vertical fracture due to excessive post preparation. Therefore, it is necessary to make further study and investigation in the design of fiber post-resin core for repairing molars. OBJECTIVE: To evaluate the clinical therapeutic effects of fiber post-resin core with different numbers of posts in the repair of molar residual roots and crowns. METHODS: A total of 54 human molar residual roots and crowns with sound root canal filing in 48 patients were selected and restored with fiber post of different numbers and resin core as wel as complete coronal restoration. There were 17 cases (20 samples) restored with single fiber post core, 16 cases (18 samples) restored with double fiber post cores, and 15 cases (16 samples) restored with three fiber post cores. They were folowed up for 24 months and the repair results were compared. RESULTS AND CONCLUSION:After 24 months of folow-up, the success rates were 85%, 94% and 94% in the single fiber post, double fiber post and three fiber post groups, respectively, and no significant difference was detected among the three groups. Five failures were observed among 54 teeth: three cases of fiber post shedding in the single fiber post group, one case of fiber post shedding in the double fiber post group, and one case of fiberpost shedding in the three fiber post group, and no root fracture occurred. Three kinds of fiber post-resin cores for repairing molar residual roots and crowns can get a better short-term clinical result. The repair effects were not different because of the different numbers of fiber posts.

Molecularly imprinted polymers for dimethoate recognition were synthesized by the precipitation polymerization technique using methyl methacrylate (MMA) as the functional monomer and ethylene glycol dimethacrylate (EGDMA) as the cross-linker. The morphology, adsorption and recognition properties were investigated by scanning electron microscopy (SEM), static adsorption test, and competitive adsorption test. To obtain the best selectivity and binding performance, the synthesis and adsorption conditions of MIPs were optimized through single factor experiments. Under the optimized conditions, the resultant polymers exhibited uniform size, satisfactory binding capacity and significant selectivity. Furthermore, the imprinted polymers were successfully applied as a specific solid-phase extractants combined with high performance liquid chromatography (HPLC) for determination of dimethoate residues in the cucumber samples. The average recoveries of three spiked samples ranged from 78.5% to 87.9% with the relative standard deviations (RSDs) less than 4.4% and the limit of detection (LOD) obtained for dimethoate as low as 2.3μg/mL.

Objective To study the effect of coenzymes complex combined with vitamin E on liver and kidney inju-ry induced by neonatal hyperbilirubinemia. Methods One hundred and fifty full-term neonatals with hyperbilirubinemia were chosen as observation groups, who were divided into mild, moderate and severe groups according bilirubin. Forty five healthy full-term newborns in the same period, who are either healthy or with physiological jaundice, were selected as con-trol group. Serum total bilirubin, gamma-glutamyl transferase (γ-GGT) , Malondialdehyde (MDA) and Cys-C were measured within 24 hours of hospital admission.The observation groups were randomly divided into regular and combined treatment groups. Coenzymes complex combined with vitamin E were given in addition to regular method to combined group while reg-ular group only received regular methods.All above biochemical indexes were tested in the 7th day after medication admin-istration. Results Serum MDA were higher in all observation groups (mild, moderate and severe groups) than in control group (P＜0.05);but the levels ofγ-GGT and Cys-C increased in moderate and severe groups compared with control group (P＜0.05). There were positive correlations (P＜0.05) between levels of serum total bilirubin with MDA,γ-GGT and Cys-C. Positive linear correlation were found between MDA with γ-GGT and Cys-C(P＜0.01). After early intervention,γ-GGT, Cys-C and MDA declined with drop of bilirubin level. This is more prominent and faster in a in combined treatment group than regular group (P＜0.05).Conclusion In hyperbilirubinemia newborns, lipid peroxidation activated by bilirubin may lead to damages of liver and kidney. Coenzymes combined with vitamin E have protective effect to these damages.

Objective To explore the reactive inhibition and electrophysiological changes under the GO/NOGO paradigm in patients with alcohol dependence (AD) in order to provide a theoretical basis for neuromechanism study of AD executive dysfunctions.Methods The GO/NOGO paradigm event related potentials (ERP) were tested in 51 AD patients and 29 healthy controls, this paradigm behavior and ERP-N1, N2 and P3 latency and amplitude were analyzed.ERPs and execution functions were followed at different time points of withdrawal(4, 9,13 weeks).Results The number of correct responses (29.18±3.03)lowered and error responses (5.16±3.77) heightened in AD patients, and differences had statistical significance compared with those in control group(32.35±2.58,3.19± 1.84, P＜0.05), and there was no group difference in response time.There was no statistical significance in group difference in N1 component under the GO/NOGO tasks and in P3 latency under GO.N2 ((3.48±2.21) μV, (4.49±3.00) pV) and P3 amplitude ((3.47±2.31) μV, (3.92±4.09) μV) decreased and N2 latency ((256.30±31.62) ms, (256.09±33.77)ms) prolonged in AD group under both GO/NOGO tasks and so did P3 latency ((355.33±25.96) ms) under the NOGO, and the differences had statistical significance.Group main effects in N2 and P3 component (P=0.000) and task main effects in N2 amplitude and P3 latency (P＜0.05) were significant,group and task interaction was significant only in P3 latency (P＜0.01).ERPs of AD patients had no notable changes at different time points of withdrawal, executive dysfunctions were the worst within the 1st week of withdrawal and gradually recovered to pre-withdrawal levels.Conclusion AD patients have lower reactive inhibition manifested mainly by weakened capacity to inhibit and adjust conflict monitor and pre-executive motor program, ERP and executive functions cannot be well improved during short-term withdrawal, and the GO/NOGO-ERP can completely reflect electrophysiological changes of reactive inhibition process of AD patients.
