Objective To detect the correlation between the periodontal bone loss and carotid calcifications by using MSCT.Methods Imaging materials of 270 patients who were suspected atherosclerosis and underwent MSCT were retrospectively studied.According to the score of carotid calcification,the patients were divided into three groups:slight calcification group (carotid calcification score <100),severe calcification group (carotid calcification score ≥100),and normal control group (carotid calcification score=0).The original images were post-processed with volume rendering(VR),multi planar reformation(MPR),curved planar reformation(CPR)and maximum intensity projection (MIP)by using EBW4.5 workstation,and then the residual teeth number and the periodontal bone loss teeth were recorded in different groups.Results On MSCT,the carotid calcification score and the number of periodontal bone loss were displayed clearly.The number of the periodontal bone loss teeth in the calcification groups were significantly higher than those in the normal control group(P<0.01).Furthermore,the number of the periodontal bone loss teeth was positively correlated with the severity of carotid calcification.Conclusion The periodontal bone loss is highly correlated with the severity of the carotid calcification.The volume reconstruction technique of MSCT is a non-invasive diagnostic testing to detect the periodontal desease and to quantify carotid calcifications.

Objective To determine the importance of aneuploidy screening in preimplantation genetic diagnosis for the couples of chromosome translocation carriers. Methods To perform 11 prenatal genetic disgnosis (PGD) cycles for 7 couples of chromosome translocation carriers from January 2006 to March 2009 in the Reproductive Medical Center, First Affiliated Hospital of Zhengzhou University. To re-analyze the well-fixed, non-multinuclear and non-debris nuclei using the probes of LSI 13, 18, 21,CEPX, CEPY to detect the aneuploidy rate which come from the PGD cycles of the couples of chromosome translocation carriers. The euploid embryo was defined as two fluorescence in situ hybridization (FISH)signals of LSI 13, 18, 21 respectively and two signals of CEPX, or one signal of CEPX and one signal of CEPY. The other abnormal signals were defined as aneuploid embryo. Results (1) A tolal of 130 nuclei from 11 PGD cycles got the integrated re-FISH signals. Nine hundred and thirty-seven FISH signals were analysized, including 304 signals from 38 euploid nuclei and the others from 92 aneuploid nuclei. (2) The number of the aneuploid nuclei from grade Ⅰ , Ⅱ and Ⅲ embryo was 20 (22%), 36(39%), and 36(39%). The number of the euploid nuclei from grade Ⅰ , Ⅱ and Ⅲ embryo was 13(34%), 17(45%),and 8(21%). There was no significant difference of aneupioidy rate between the embryos form different grades (P>0.05). However, the rate of aneuploid nucleus from good quality embryos (grade Ⅰ + grade Ⅱ) was 60% (59/92). (3) The euploidy rate was 71.4% (30/42) from balanced embryos, while 9.1%(8/88)from unbalanced embryos. There was significant difference between them (x2=53.4, P<0.05).The rate of aneuploidy from balanced embryos was lower than those from unbalanced embryos (P<0.05).Conclusions Since higher rate of aneuploidy was detected in embryos of the couples of chromosome translocation carriers. It is advisable to recommend the FISH re-analysis for aneuploidy screening to preimplantation genetic diagnosis for the couples of chromosome translocation carriers.

BACKGROUND:As the rapid development of oral implantation and restoration techniques, as wel as the increasing enlargement of indications, angulated abutments have been widely used. Posterior teeth region, as the weight-loading region of occlusion, can bear great force from the implants, the assessment of angulated abutments in posterior teeth region has clinical value.
OBJECTIVE:To evaluate the short-term clinical efficacy of angulated abutments on the implant denture in posterior teeth region.
METHODS:From January 2008 to January 2013, 114 patients with 175 ITI implants in the posterior teeth region were included in this study and they al underwent single-crown restoration. The involved patients were divided into angulated abutment group and straight abutment group. Periodontal probing depth, modified plaque index, modified sulcus bleeding index and peri-implant crestal bone loss in two groups were recorded at 6 months and 2 years after restoration. Cumulative survival rate of the implant denture was calculated by life-table analysis.
RESULTS AND CONCLUSION:There was no significant difference in periodontal probing depth, modified plaque index, and modified sulcus bleeding index between two groups (P>0.05). The annual crestal bone loss showed no significant difference between two groups (P>0.05). Moreover, the 5-year cumulative survival rate with 15° and 20° abutments was 95.6%, and that with straight abutment was 96.4%. The angle of abutments has no correlation with peri-implant soft tissue and peri-implant crestal bone loss, implant restorations with 15° and 20° angulated abutments may be successful y used in the posterior region, whereas the long-term effects need further research.
