Objective:To analysis the effects of alprostadil and yishen huashi particles on blood glucose,blood lipid,renal function and urinary podocyte proteins of patients with diabetic nephropathy.Methods:98 patients with diabetic nephropathy were selected and randomly divided into the control group and the experimental group with 49 cases in each group.The patients in the control group were treated with alprostadil,while the patients in the experimental group were treated with yishenhuashui particles on the basis of the control group.Then the curative effect,the levels of glycosylated hemoglobin (HbAlc),blood glucose (FPG),2 h postprandial blood glucose (2h PG),triglycerides (TG),total cholesterol (TC),high-density lipoprotein (HDL-C),low density lipoprotein (LDL-C),blood urea nitrogen (BUN),creatinine (Cr),β2 microglobulin (β2-MG),bladder inhibition (Cys-C) and urinary podocyte proteins (PCX) in the two groups were observed and compared between the two groups before and after the treatment.Results:The total effective rate of experimental group was higher than control group (P＜0.05).After treatment,there was no statistically significant difference about the HbA1c,FPG and 2 HPG between the two groups (P＞0.05).After the treatment,the levels ofTG,TC,LDL-C,BUN,Cr,β2 MG,Cys C,PCX and urinary nephrin/urine Cr of the experimental group were lower than those of the control group (P＜0.05).The HDL-C of experimental group was higher than that of the control group (P＜0.05).Conclusion:The curative is effect of alprostadil and yishen huashi particles in treatment diabetic nephropathy patients,can conducive to the improvement of blood glucose,blood lipid,renal function,reduce the concentration of urinary podocyte related proteins.

Objective To explore the relationship between the spot size and the result of ploidy analysis in the detection technology based on single-particles, and to fix the scope of spot thickness on the basis of the experimental result.Methods The influence of spot thickness on voltage signals produced by single cells was analyzed.The parameters of the beam shap system in the incident field were designed and optimized on ZEMAX.Finally, according to the cells′diameter, the target size of spots was set.A set of spots of different thickness and of Gaussian distribution obtained from the optical experimental platform was used to conduct ploidy detection experiments.Results Target spots were both obtained from ZEMAX simulation and the optical platform.When the spot thickness was larger than both monocytes and coenocytes, the mean fluorescence intensity ratio was 2.03,which met the demand of the index.Conclusion When the height of the pulse is used to represent the fluorescence density, the relative size of spots and cells will affect the result of ploidy detection.Only when spot thickness is larger than cells is the ploidy ratio accurate.

Objective To present a new algorithm of real-time peak detection for pulse signals based on FPGA , which is known as the dynamic threshold with half peak detection method ( DT-HP ) .Methods With Gaussian-shaped pulse signals as the target , the method was improved from conventional methods .The FPGA detection process of the algorithm required no more than three detection parameters: the starting point , the maximum value and the pulse width .Results The algorithm solved the floating baseline and repeating detection that occur in traditional methods .Compared with the results of polynomial fitting method and flow cytometry , the difference was only 3.2% and 9.3%.Conclusion The algorithm takes less time ,RAM, and cache while allowing floating baseline detection , which can be used as an effective method for rapid detection in FPGA .

Objective To identify the different causes of atrial fibrillation (AF) in Chinese by coronary artery angiography,and to compare the episode of stroke in different patients.Method A total of 782 adult patients diagnosed with AF were identified from Anzhen Hospital over a 8-year period.There were 273 patients with rheumatic valvular AF and 509 patients with nonvalvular AF.The results of electrocardiogram,echocardiography and coronary artery angiography were retrospectiwely analyzed to find out the proportion of causes and to compare the episode of stroke in patients with rheumatic valvular AF with those having nonvalvular AF.Results The patients with rheumatic valvular atrial were significantly younger than of coronary heart disease (52.40?5.03 years old vs 64.30?3.25 years old,P
