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.

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°.

Objective Vascular mild cognitive impairment(VaMCI) refers to mild cognitive impairment caused by or associated with vascular causes.This study aims to investigate the characteristics of the cognitive impairment in patients with vascular mild cognitive impairment (VaMCI).Methods Seventy-five patients with VaMCI(VaMCI group) and 38 healthy old subjects whose age, sex and education level match the VaMCI group patients(control group) were recruited from the department of Neurology, Beijing Chaoyang Hospital, Capital Medical University between Jan 2016 and June 2016.The neuropsychological examinations were used to evaluate the severity of cognitive impairment, specifically including the Minimum Mental State Examination(MMSE), Montreal cognitive assessment scale(MoCA), Clinical Dementia Rating(CDR), Activity of Daily Living Scale(ADL), Hachinski ischemic score table, Hamilton Depression Scale(HAMD) and Auditory Verbal Learning Test(AVLT).The Fazekas scale was used to assess the severity of white matter lesions, and the medial temporal lobe atrophy rating scale(MTA) was used to evaluate the atrophic severity of medial temporal lobe.Results The overall cognitive function score in VaMCI group was significantly lower than the control group [MMSE [25.7±2.3 vs 28.4±2.0] MoCA [22.8±3.9 vs 26.3±3.7]], the differences was statistically significant(P<0.05);as well as the AVLT-I [5.1±1.0 vs 8.9±1.9], AVLT-D [3.7±1.0 vs 9.8±1.5] and AVLT-R [7.6±1.9 vs 12±1.5] scores in VaMCI group was significantly lower than the control group, the differences was statistically significant(P<0.05), which suggested patients with VaMCI have overall cognitive impairment, especially memory impairment.But Fazekas and MTA scores in VaMCI groups were higher than the control group, the differences was statistically significant(P<0.05).Correlation analysis showed that the scale of medial temporal lobe atrophy had a negative relationship with the performance of MoCA (r=-0.434,P=0.002).Conclusion Our findings demonstrate patients with VaMCI have significant cognitive impairment, especially memory impairment, which may be correlated to the severity of the white matter lesions and the medial temporal lobe atrophy.

Objective To investigate the clinical manifestations,pathological features,treatment and prognosis of nongesta-tional choriocarcinomas.Methods The clinicopathological data in 4 cases of nongestational choriocarcinoma were retrospectively analyzed and the relevant literatures were reviewed.Results All 4 patients had no confirmed diagnosis at first visit to hospital.All patients received the operative therapy and postoperative bleomycin,etoposide and cis-platinum (BEP)regimen chemotherapy.The followed up lasted for 3-32 months.One case died at postoperative 26 months due to pulmonary metastasis;one case was loss of follow up;two cases had relatively favorable condition.Conclusion Nongestational choriocarcinoma is a rare and highly invasive trophoblastic neoplasm,and is prone for early distant metastasis.The treatment is recommended to adopt operation combined with postoperative combined chemotherapy of multiple drugs.

The changes of alanine amino-transferase (ALT) in plasma, glutathione (GSH) in the whole blood, the malondialdehyde(MDA) and glutathione peroxidase (GSH-Px) in the liver's tissue in mice were studied in the group with azathioprine (Aza) 10 mg?kg-1?d-1 and in the group with Aza mixed selenium (Se) 1 mg ?kg-1?d-l for 1 and 2 weeks. The results showed that in the Aza group, the levels of ALT, MDA increased and that of GSH, GSH-Px decreased significantly at 1 wk and 2 wk. But in the Se group the levels of ALT, MDA decreased and that of GSH, GSH-Px increased significantly, which approached the nor-mal level. The hepatocytes degeneration and necrosis were observed by light microscope in Aza group but not in Se group. The results indicated that Se had protective effects on Aza hepa-totoxicity in mice.

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.
