2.3-dimensional finite element analysis on stress distribution in maxillary with All-on-4 implants in different arch forms
Journal of Jilin University(Medicine Edition) 2014;(6):1182-1186
Objective To explore the effect of different arch forms of maxillary models on stress distribution of peri-implant of All-on-4 implants with 3-dimensional finite element, and to provide evidence for the improvement of implant achievement ratio in clinic. Methods 3-dimensional finite element analysis models of Tapered,Square and Ovoid arch form maxillary based on the MBTTM Arch Form Templates were constructed by using Solidworks software.The cortical bone thickness was defined as 2 mm at all points.The implants with 13 mm in length were inserted between the mental foramina.The 2 posterior implants were set at 4 inclination angle,from 0°to 45°.All implants were splinted with superstructure.A 100 N pressure was applied to 2 kinds of loading positions on the superstructure models. The maximum Von-Mises stress on cortical bone around the implants was measured by using Abaqus software.Results The maximum Von-Mises value in maxillary cortical bone with All-on-4 implants in 3 arch forms showed significant differences. In Square model the concentration of stress was advanced with the increasing of implant inclination angle;In Ovoid model, the maximum Von-Mises value was observed at 1 5°in posterior region,and was increased significantly by pasted 15°in anterior region;In Tapered model,the Maximum Von-Mises value was increased greatly at 45°. Conclusion Arch forms have appreciable impact on stress distribution of peri-implant.In Square arch form,the inclination of implant should be avoided;in Ovoid arch form, the inclination angle should be under 15°;in Tapered arch form,the inclination should be under 30°.

Chinese Journal of Diabetes 2017;25(2):144-148
Objective To investigate the changesof glomerular filtration rate(eGFR)in type 2 diabetic patients with normal serum creatinine(Scr)and serum cystatin C(Cys-C). Methods A total of 166 patients with type 2 diabetes mellitus admitted into our hospital from January 2014 to September 2015 were enrolled in this study and divided into three groups according to the level of Scr and Cys-C:T2DM patients with normal Scr and Cys-C (normal group,n =109),T2DM patients with normal Scr and high level of Cys-C (high Cys-C group,n=40),and T2DM patients with high levels of Scr and Cys-C (high Scr Cys-C group,n=17). Normal group were further divided into two subgroups according to the level of eGFR:eGFR≥90 ml/(min·1.73 m2 )subgroup and eGFR<90 ml/(min·1.73 m2 )subgroup.Clinical characteristics and laboratory datawere collected in all subjects. eGFR were measured by 99mTc-DTPA nephro-dynamic imaging. Results The average value of eGFR were significantly different in normal group(82.68±13.45)ml/(min·1.73 m2 ),high Cys-C group(67.93 ±14.01)ml/(min·1.73 m2 )and high Scr,Cys-C group (50.54±15.10)ml/(min·1.73 m2 ). In normal group,the proportion of patients with eGFR equal or greater than 90 ml/(min·1.73 m2 )was 26.6%,patients with eGFR ranged from 60 to 89 ml/(min·1.73 m2 )was 72.5%,patients with eGFR ranged from 30 to 59 ml/(min·1.73 m2 )was 0.9%. After follow-up for three months,in normal group,the proportion of patients with CKD stage1 was 4.6%,patients with CKD stage 2 was 34.9%,and patients with CKD stage 3 was 0.9%.Multivariate logistic regressionanalysis in normal group showed that female,older age,higher TC,lower LVEF were risk factors for eGFR decline (P <0.05). Conclusion In T2DM patients with normal Scr and Cys-C, 73.4% of them had mild to moderate eGFR decline,and 40.4%entered CKD stage in this study.eGFR should be evaluated especially in T2DM patients with risk factors including female,older age,higher TC and lower LVEF.

Methods: The work was performed by analysis of HPLC FPS and 4 dimensional UV FPS. Results: Their 4 dimensional UV FPS were very similar with each other, and the common peaks ratio of the components extracted from Peru's Ginseng healthcare product, Radix Ginseng with absolute alcohol was larger than that of the components extracted from Peru's Ginseng healthcare product and Panax quinquefolium. The variant ratio between the healthcare product and Radix Ginseng were more similar and much lower than that between the healthcare product and Panax quinquefolium. Conclusion: The components extracted from the healthcare product with absolute alcohol are the same as that from Radix Ginseng and are of quite large difference from the components from Panax quinquefolium.

Objective To investigate the gene expression of sodium pump α-subunit in aortic smooth muscle of 1-kidney-1-clip (1k1c) hypertensive rats. Methods 1k1c hypertensive rats were prepared by partially ligating the left renal artery and removing the right kidney. 4 weeks later, all the rats were killed and sodium pump α1- , α2-, and α3-subunit in aortic smooth muscles were detected with reverse transcription p ol ymerase chain reaction (RT-PCR) method and immunohistochemical assay at both mR NA and protein levels, respectively. Resulsts Changes in the expression of sodi um pump α-subunit gene were found in aortic smooth muscles of 1k1c hypertensiv e rats: α1-su bunit increased at both mRNA protein levels, while α2- and α3-subunits r emained without changes. Conclusions There were great changes in the gene expression of so dium pump α-subunit in aor tic smooth muscles of 1k1c hypertensive rats, which might be related to the development of hypertension in this hypertensive model.

ObjectiveTo explore the distribution of sodium pump α-subunit isoforms at both mRNA and protein level in normal Sprague-Dawley(SD) rats. MethodsWith RT-PCR (reverse transcription-polymerase chain reaction) and immunohistochemical assay, sodium pump α1-, α2-, andα3-subunit isoforms were detected at mRNA level and protein level in the myocardium, liver, kidney, adrenal gland, aortic smooth muscle, pituitary and hypothalarnus in normal rats. ResultsSodium pump α1-, α2-, and α3-subunit isoforms distribute in a tissue-specific fashion in normal SD rats. α1 and α2 are the main isoforms and α3 is much less in myocardium. α1 is more than α2 or α3 isoform at mRNA level in liver, while all of α1-,α2-, and α3-isoform are less expressed at protein level. α1-isoform is abundantly but α2 and α3 are less expressed both at mRNA and protein levels in kidney. α2isoform is just more than α1 and α3 isoforms in aortic smooth muscle. All of three isoforms are expressed abundantly in pituitary. α2 and α3 are more and α1 is less expressed in hypothalamus. ConclusionThe results of this study have revealed the distribution of sodium pump α-subunit isoforms at both mRNA and protein level in normal SD rats, which might be helpful for the further studying the physiologic and pathologic roles of sodium pump.
