BACKGROUND:Occlusal scheme is the key of a successful complete denture, and how to choose a suitable occlusal scheme is a long-term problem for prosthodontists.
OBJECTIVE:To systematical y review the clinical effects of two occlusal schemes for complete denture.
METHODS:An electronic search of Cochrane Library, Medline/PubMed, EMBASE, CNKI, Wanfang and CBM databases were performed for clinical trials published before October 2013 using the key words of“complete denture”,“edentulous”,“occlusion”,”balanced”,“lingualized”,“anatomic”in Chinese and English. A manual searching of 11 relevant journals concerning oral medicine and reference lists of selected articles were conducted. Two reviewers independently extracted the data and assessed the quality of the included literature. Total y, 628 papers were retrieved.
RESULTS AND CONCLUSION:Only five articles met the inclusion and exclusion criteria. Of these five articles, one study showed lingualized occlusion dentures were more satisfactory than bilateral balanced occlusion dentures in denture retention (P<0.05);one study showed the lingualized occlusion exhibited lower scores for uncomfortable eating and avoiding particular foods (P<0.05), but higher scores for uncomfortable dentures than the bilateral balanced occlusion (P<0.05);one study showed the lingualized occlusion dentures have better masticatory efficiency and better protective role in alveolar bone than the bilateral balanced occlusion dentures (P<0.05);another two studies showed no significant differences in the overal satisfaction between lingualized occlusion and bilateral balanced occlusion dentures. These findings indicate that the lingualized occlusion is similar to bilateral balanced occlusion in the satisfaction of patients, masticatory efficiency, appearance and speech, but the lingualized occlusion dentures are better for severe alveolar bone resorption patients in terms of masticatory efficiency and better protection of alveolar bone.

Objective To evaluate the effect of transcutaneous electrical acupoint stimulation (TEAS) on sedative efficacy during induction of anesthesia with propofol.Methods Patients,of ASA physical status Ⅰ or Ⅱ,aged 21-69 yr,scheduled for elective thyroid surgery,were randomly divided into 2 groups using a random number table:control group (group C) and TEAS group.TEAS was applied to bilateral Hegu and Neiguan acupoints for 30 min.The frequency was 2/100 Hz,wave length was 0.2-0.6 ms and the intensity was maintained at about 8-12 mA according to the current that could be tolerated.Induction of anesthesia was started at the end of TEAS.Sequential method was used to determine the median effective target plasma concentration (EC50) of propofol causing loss of consciousness in each group.The initial target plasma concentration of propofol was 3 μg/ml.BIS value was recorded every 30 s within 5-8 min after loss of consciousness and the average BIS value was calculated.It was considered to be positive response when the average BIS value was below 50.The target concentration of propofol was decreased/increased by 0.3 μg/ml in the next patient.Results EC50 of propofol causing loss of consciousness was 3.08 μg/ml in group TEAS,and 3.70 μg/ml in group C,and there was significant difference between the two groups.Conclusion TEAS can enhance the sedative efficacy during induction of anesthesia with propofol in the patients.

AIM: To observe the effect of intraocular lens ( IOL) implantation on visual acuity and contrast sensitivity in patients with cataract.
METHODS: Fifty - eight cases ( 72 eyes ) cataract patients with regular cornel astigmatism, in our hospital from May 2014 to May 2015 were randomly divided into two groups to undergo phacoemulsification and IOL implantation: the observation group: 29 cases (36 eyes) received multifocal toric IOL implantation; the control group: 29 cases (36 eyes) received monofocal toric IOL implantation. Uncorrected distance visual acuity ( UCDVA), uncorrected near visual acuity ( UCNVA), best corrected distance visual acuity (BCDVA), the best corrected near visual acuity ( BCNVA ), total eye astigmatism, and the dark contrast sensitivity were observed for these patients at 1 and 6mo after cataract surgery.
RESULTS: There were no statistical significant difference between the two groups at postoperative 1, 6mo on UCDVA, BCNVA, BCDVA and total eye astigmatism(P>0. 05). UCNVA of observation group at 1 and 6mo were better than those of control group ( P <0. 05); there were statistically significant difference in high frequency comparison at the sixth postoperative months (P<0. 05).
CONCLUSION: Both monofocal toric IOL implantation, and aspheric multifocal toric IOL implantation for cataract with regular corneal astigmatism are effective to improve visual acuity. But the latter treatment would contribute to the improvement of uncorrected near visual acuity and the dark contrast sensitivity.

As an important component of the event related potential (ERP), late positive potential (LPP) is an ideal component for studying emotion regulation. This study was focused on processing and analysing the LPP component of the emotional cognitive reappraisal electroencephalogram (EEG) signal. Firstly, we used independent component analysis (ICA) algorithm to remove electrooculogram, electromyogram and some other artifacts based on 16 subjects' EEG data by using EGI 64-channal EEG acquisition system. Secondly, we processed feature extraction of the EEG signal at Pz electrode by using one versus the rest common spatial patterns (OVR-CSP) algorithm. Finally, the extracted LPP component was analysed both in time domain and spatial domain. The results indicated that (1) From the perspective of amplitude comparison, the LPP amplitude, which was induced by cognitive reappraisal, was much higher than the amplitude under the condition of watching neural stimuli, but lower than the amplitude under condition of watching negative stimuli; (2) from the perspective of time process, the difference between cognitive reappraisal and watching after processing with OVR-CSP algorithm was in the process of range between 0.3 s and 1.5 s; but the difference between cognitive reappraisal and watching after processing with averaging method was during the process between 0.3 s and 1.25 s. The results suggested that OVR-CSP algorithm could not only accurately extract the LPP component with fewer trials compared with averaging method so that it provided a better method for the follow-up study of cognitive reappraisal strategy, but also provide neurophysiological basis for cognitive reappraisal in emotional regulation.

ObJective To locate the cysteine-rich domains(CRD) of murine 4-1BB binding to its natural ligand. Methods A serial soluble extracellular CRDs of routine 4-1BB and 4-1BBL fusion proteins was constructed and prepared. The binding of purified 4-1BB-Igs to 4-1BBL and 4-1BB monoclonal antibody were tested using ELISA assay and Western blot analysis. Blocking experiment with 4-1BBL and 4-1BB mon-oclonal antibody was performed by ELISA assay. Results All truncated overlapped proteins containing ex-tracellular CRD Ⅱ of murine 4-1BB were able to bind to 4-1BBL by ELISA assay, excepting the CRD Ⅰ do-main alone. A 4-1BB monoclonal antibody proved to block the interaction of 4-1BB and 4-1BBI, was also able to bind to CRD Ⅱ. Conclusion Murine 4-1BBL whose specificity was mapped to CRD Ⅱ of 4-1BB ex-tracellular region with a possible conformational structure.

Objective To retrospectively investigate the effects of CYP3A5 * 3,CYP3A4 * 18B and CYP3A5-CYP3A4 phenotype on the C0,D and C0/D of tacrolimus (Tac) in renal transplantation recipients.Methods The CYP3A5 * 3 and CYP3A4 * 18B genotypes of the 61 patients were detected by DNA direct sequencing,and the C0 was detected by ELISA.The differences of C0,D and C0/D on the day 14,and month 1,2 and 3 after transplantation were compared among different genotypes of recipients treated with Tac.Results The frequency of the CYP3A5 * 3 and CYP3A4 * 18B was 74.6％ and 26.2％ respectively.When the D of the recipients with CYP3A5 * 1 ( * 1/* 1 + * 1/* 3)was 1.3-1.6 times to theCYP3A5*3/*3,theC0 of *3/*3 group was 1.1-1.5 times to the * 1group,and the C0/D was 1.8 2.4 times to the CYP3A5 * 1.For CYP3A4,the D of CYP3A4 * 18B group ( * 1/* 18B+ * 18B/* 18B) was 1.2-1.5 times to the CYP3A5 * 1/* 1,but the C0 of 1/* 1was 1.2-1.4 times to the * 18B,the C0/D was 1.5-1.8 times to the * 18B.For the CYP3A5 CYP3A4 phenotype,the D of the recipients with AAAA was 1.3-1.7 times to the GG-GG,the C0 of GG-GG was 1.5-2 times to the AA-AA,the C0/D of the recipients with G@GG was 2.5-3 times to the AA-AA.In the recipients with C0/D above or below the median of C0/D,the distribution of CYP3A5,CYP3A4 and CYP3A5-CYP3A4 phenotypes was different significantly.Conclusion There is a significant correlation between the CYP3A5,CYP3A4 and pharmacokinetics of Tac.It's more powerful evaluating the CYP3A5-CYP3A4 phenotype rather than just one genotype of the recipients.So detecting the CYP3A5 * 3 and CYP3A4 * 18B genotypes prior to transplantation is meaningful for us to determine an appropriate initial and long-time dosage of Tac.
