Objective To study the changes in echocardiography in normotensive patients with type2 diabetes mellitus (T2DM) in order to establish early diagnosis and give preventive measures for diabetic cardiomyopathy (DCM). Methods Microvasculopathy was diagnosed in T2DM patients when microalbuminuria exceeded 15ml/min. Fifty-four T2DM patients were divided into two groups: group A (patients without microvasculopathy, n=32 ), group B (patients with microvasculopathy, n=22). All of T2DM were submitted to echocardiography and the results were compared with healthy people of matched sex and age (group C, n=20). Results There were no differences in systolic function parameters among the groups. Left ventricular mass index (LVMI) was higher in two groups of diabetics compared with group C. Diastolic dysfunction of various degrees was found in the two groups of diabetics, regardless of the presence of microvasculopathy, with a manifestation of a decrease of blood flow velocity in early diastolic phase and increase in late diastolic phase (P

Objective To investigate the association between peripheral white blood cell (WBC) count and the carotid intimal-medial thickness (cIMT) in middle-aged and elderly Chinese of suburban area of Shanghai.Methods A total of 2 519 subjects aged 40 years or older from Jiading District,Shanghai were recruited to undergo questionnaire interview,anthropometric measurements,fasting blood sampling,and carotid B-mode ultrasonography.After excluding subjects with biochemical index missing,WBC count ＞ 10× 109/L as well as those with known myocardial infarction,cerebral infarction,coronary heart disease,and those taking lipid-lowing agents,2 239subjects were included in this analysis.Results Increased WBC count was associated with more unfavorable metabolic risk profiles.With the increasing quartiles of WBC count,cIMT were 0.558,0.570,0.573,and 0.587mm respectively(P for trend ＜ 0.01).As compared with participants in the first WBC quartile,the risks of cIMT thickening were increased by 79％,109％ in males and 29％ in females (P＞ 0.05 in females).Multiple linear regression model showed that peripheral WBC count was an independent risk marker for cIMT thickening,especially for neutrophil and monocyte count.Conclusion A high-normal WBC count was significantly associated with cIMT thickening in middle-aged and elderly Chinese of suburban area of Shanghai,especially in males.

Abstract?AlM:To investigate the choice of different treatments for malignant glaucoma.? METHODS: ln this retrospective case series, 21 malignant glaucoma patients ( 21 eyes ) admitted in Wuhan General Hospital of Guangzhou Military Command from May 2012 to May 2013 were analyzed. Sixteen eyes ( 76%) developed malignant glaucoma after filtration surgery, 3 eyes ( 14%) after EX - PRESS glaucoma filtration device, 2 eyes ( 10%) after glaucoma filtration Ahmed valve implantation. Main Outcome of corrected visual acuity, intraocular pressure ( lOP ) , anterior chamber depth and complications were detected.?RESULTS: lOP recovered by drug control in 13 eyes, anterior chamber depth. Four eyes were treated by vitreous water- bag aspiration combined with anterior chambers reconstructing. Two eyes were treated by cataract extraction and intraocular lens implantation. Two eyes were treated by posterior capsule excision combined with anterior vitrectomy. lOP before and after treatment was 29. 81±4. 98, 12. 71±3. 77mmHg, respectively (P=0. 00). Anterior chamber depth before and after treatment was 0.41± 0. 34, 2. 13 ± 0. 54mm, respectively (P = 0. 00). Corrected visual acuity before treatment was 0. 19 ± 0. 17, after treatment was 0. 20±0. 16 (P= 0. 36). Except for vitreous hemorrhage in 1 eye, there were no ocular or systemic adverse events observed in all patients.? CONCLUSlON: lt is good to diagnose malignant glaucoma in early period, and treated it step by step. For this can reduce lOP and restore anterior chamber.

Objective The purpose of this study was to develop a high-throughput micro-plate radiobinding assay (RBA) of glutamic acid decarboxylase antibody (GAD-Ab) and to evaluate its clinical application. Methods 35labeled GAD65 antigen was incubated with sera for 24 h on a 96-well plate, and then transferred to the Millipore plate coated with protein A, which was washed with 4℃ PBS buffer, and then counted by a liquid scintillation counter. The GAD-Ab results were expressed by WHO standard unit (U/ml). A total of 224 healthy controls, 162 patients with type 1 diabetes mellitus(T1DM) and 210 patients with newly diagnosed type 2 diabetes (T2DM) were recruited. A total of 119 TI DM and healthy cases with gradually changing GAD-Ab levels were selected to compare the consistency of micro-plate RBA with conventional radioligand assay (RLA). Blood samples were obtained from the peripheral vein and finger tip in 32 healthy controls, 35 T1DM and 24 T2DM patients, and tested with micro-plate RBA and then compared with the conventional RLA to investigate the reliability of finger tip sampling. Linear correlation,student's t-test, variance analysis and receiver operating characteristic (ROC) curve were performed using SPSS 11.5. Results (1) The optimized conditions of micro-plate RBA included 2 μl serum incubated with3 ×104 counts/min 35S-GAD for 24 h under slow vibration, antigen-antibody compounds washed 10 times by 4℃ PBS buffer, and radioactivity counted with Optiphase Supermix scintillation liquid. (2)The intra-batch CV of the micro-plate RBA was 3.8%- 10.2%, and the inter-batch CV was 5.6%- 11.9%. The linearity analysis showed a good correlation when the GAD-Ab in serum samples ranged from 40.3 to 664 U/ml and the detection limit of measurement was 3.6 U/ml. The results from Diabetes Autoantibody Standardization Program (DASP) 2005 showed that the sensitivity and specificity for GAD-Ab were 78% (39 positive among 50 new-onset T1DM) and 98% (2 positive among 100 healthy controls). The results of GAD-Ab obtained with micro-plate RBA and RLA were closely correlated (r=0.915,P<0.001) with a high concordance level of 97.5% and a Kappa value of 0.95. (3)TI DM and T2DM patients showed higher positive rates for GAD-Ab than the healthy controls(46.9% and 5.2% vs 0.89% ,X2=123.5 and 10. 1 ,P <0.001 and <0.01, respectively). (4)The consistency of GAD-Ab measurement with RBA using finger tip blood and RLA measurement using venous blood was 96.7% (r =0.946,P <0.001, Kappa value: 0.905). Conclusions The micro-plate RBA of GAD-Ab has high sensitivity, specificity and reproducibility, and can be measured with finger tip blood sampling. It might be a better alternative for clinical practice.
