Objective Increased renal mast cells have been found in significant correlation with clinicopathological features of diabetic nephropathy ( DN) .However, the exact pathological significance of mast cells still remained to be elucidated.As one of the most abundant serine proteases, tryptase is specifically expressed by mast cells.The study was to observe the expression of tryptase in the urine of patients with diabetic nephropathy and realize the pathological significance of urinary tryptase and renal mast cells in the development of diabetic nephropathy. Methods Urine samples from 103 patients with diabetic nephropathy who were hospitalized at the clinical unit of the nephrology centre of Jingling Hospital from January 2012 to June 2013 were collected.According to concentra-tion of urinary albumin excretion rate, the patients were conducted to early-stage DN group (microalbuminuria,n=10), middle-stage DN group (proteinuria stage, n=31) and end-stage DN group (renal insufficiency stage,n=62).Meanwhile, urine samples from 20 normal persons were taken as the normal control group.Tryptase level in each urine sample was measured by using an ELISA kit.The average tryptase levels were compared among different groups and the correlation between urinary tryptase level and clinical indices was analyzed. Results ①In most cases, tryptase was not detected in the urine samples from normal persons(0.7 ±1.4 ng/mg creati-nine).However, the urinary trypatse level increased significantly with the development of diabetic nephropathy (11.6 ±10.5 ng/mg creatinine for early stage, 29.7 ±19.2 ng/mg creatinine for middle stage, and 44.6 ±43.4 ng/mg creatinine for late stage group).②The urinary tryptase level was found in significant correlation with ser-um creatinine (r=0.325, P<0.01), serum cystatin C (r=0.391, P<0.01), serum urea nitrogen (r=0.27, P<0.01), 24 hour uri-nary protein (r=0.389, P<0.01), urine C3 (r=0.276, P<0.05), urine retinol-binding protein (r=0.365, P<0.01), urine lysozyme (r=0.461, P<0.01), urine N-acetyl-β-glucosaminidase level (r=0.568, P<0.01), urinary kidney injury molecule-1 (r=0.434, P<0.05) and interleukin-18 level (r=0.375, P<0.05).No significant correlation was found between urinary tryptase level and age, gender, fasting blood sugar, postprandial blood sugar, HbA1c, triglyceride, high density lipoprotein or low density lipo-protein. Conclusion Mast cells play an important role in the development of diabetic nephropathy and might be a novel and effective target for the treatment of DN.

Objective:To explore the relationship among blood glucose,blood lipid levels,peripheral blood white cells and slow coronary flow (SCF).Methods:Clinical data of 183 patients receiving angiography in our hospital from Apr 2010 to Apr 2013 were retrospectively analyzed.Patients with TIMI grade 2 or lower coronary blood flow were defined as SCF;patients were divided into SCF group (n=93)and normal control group (n=90).Levels of blood lipid,glycosylated haemoglobin (HbA1c),hematocrit,and peripheral blood white cell levels were measured and compared between two groups.Results:Compared with normal control group,there was significant reduction in high density lipoprotein cholesterol (HDL-C) level [(1.21 ± 0.26)mmol/L vs.(1.12 ± 0.28)mmol/L,P =0.043],and significant rise in HbA1c level [(5.41±0.50)% vs.(5.83±0.45)%,P =0.01],hematocrit [(0.41 ±0.04)vs.(0.43±0.07),P =0.01]and white blood cell count [(6.1±1.6)109/L vs.(6.7±1.7)109/L,P <0.05]in SCF group.Logistic analysis indicated that white cell count was the risk factor of SCF (OR 1.920,95% CI 1.234~2.987,P =0.004).Conclusion:Levels of high density lipoprotein cholesterol,glycosylated haemoglobin, hematocrit and white blood cell count are related to slow coronary flow,and elevated white blood cell count may be a risk factor aggravating slow coronary slow.

Objective To compare the curative effect of perindopril and metoprolol in the treatment of diabetic patients with asymptomatic cardiac insufficiency.Methods According to the method of random numbers, 152 diabetic patients with asymptomatic cardiac insufficiency were divided into the observation group and control group,with 76 cases in each group.The observation group was given with perindopril treatment,while control group was given with metoprolol treatment.The cardiac function index,glycosylated hemoglobin,BNP levels,the incidence of cardiac insufficiency and the occurrence of adverse drug reactions before and after treatment were compared.Results There were no significant differences in LVEF,Tei index and E/A between two groups before treatment (all P >0.05 ).Compared with before treatment,the cardiac function indexes of the two groups were significantly improved after treatment(t=5.96,4.83,4.91,10.22,5.68,5.18,all P<0.05),but the observation group were improved more significantly(t=5.64,4.67,5.03,all P<0.05).Before and after treatment,there was no significant difference in the levels of glycosylated hemoglobin(all P>0.05),and the difference between the two groups was not statistically significant(all P>0.05).The BNP levels of the observation group before and after the treatment were (515.43 ± 58.85)pg/mL and (214.43 ±32.42)pg/mL respectively,of which the control group were (513.94 ±59.11)pg/mL and (263.32 ±43.31)pg/mL respectively,and after treatment,the BNP levels of the two groups were significantly decreased(t=23.45,17.68,all P<0.05),of which the observation group decreased more obvious(t=6.97,P<0.05).The cardiac insufficiency incidence of the observation group was 3.95%,which was significantly lower than 14.47% of the control group(χ2 =5.03,P<0.05).The incidence of adverse drug reactions had no obvious differ-ences in both groups(χ2 =0.08,P>0.05).Conclusion Using perindopril in treatment of diabetic patients with asymptomatic heart function can obviously improve cardiac function,reduce the incidence of BNP and cardiac insuffi-ciency.It has the clinical curative effect and high safety.

Objective To evaluate the feasibility of multi-parameter MRI in diagnosing ovarian endometrial cysts. Methods Pelvic MRI of 68 patients with confirmed pathological diagnosis were retrospectively reviewed. The patients were divided into ovarian endometriosis (35 patients with 42 lesions, group A) and other cystic lesions (33 patients with 38 lesions , group B).The signal intensity value of T1WI, T2WI of cyst fluid and iliopsoas, ADC value, phase values and R2*values were obtained, cyst fluid/iliopsoas ratios (T1R and T2R) were calculated. The non-parametric Mann-Whitney U test was employed to compare parameter values between the two groups. The values of diagnostic performance were analyzed by using receiver operating characteristic curve (ROC). Use the Logistics regression parameters of diagnostic efficacy to select the highest Youden index for the best parameter association after combining the parameters step by step. Results The median of T1R, T2R, ADC, phase, T1R and R2*values for group A were 3.39, 5.28, 1.20×10-3 mm2/s,2.19×10-2, 15.08 Hz respectively, and that of group B were 0.91, 10.85, 2.64×10-3mm2/s,2.67×10-2, 3.01 Hz, respectively. There were statistically significant difference between the two groups (P<0.01).The AUC of T1R, T2R, ADC value, phase values and R*2 value were 0.930, 0.874, 0.891, 0.685 and 0.924 respectively, and there was no difference among them (P>0.05). When combining T1R, ADC value, R2*value together, the Youden index (0.849 7) was highest. Conclusion Combining T1R, ADC and R2* values can provide an effective way to discriminate endometrial ovarian cyst from other ovary cystic lesions.

Objective To develop a scale for evaluating the curative effect of traditional Chinese medicine (TCM) for liver disease under the guidance of the theory of TCM, and to improve the TCM efficacy evaluation standard system for liver disease. Methods According to the TCM theory, the concept model of the liver disease-specific scale was built in combination with the international connotation of QOL and patient-reported outcomes ( PRO). A primary clinical scale was established after item pool screening, field test, culture adaptation and clinical pre-survey by the research staff. Finally, 200 questionnaires were distributed and 198 questionnaires were reclaimed. Statistical analysis was conducted to choose the items. Results All the selected items were analyzed by the different statistical methods, including significance grading, discrete tendency ( coefficient of variation ) method, stepwise regression analysis, discriminatory analysis, Cronbach’s al pha, and principal component analysis and factor analysis. A self-reported subjective scale and a perceived objective scale were developed, including 17 self-reported subjective items and 13 objective items. Conclusion According to the TCM theory and the international connotation of QOL, the scale of assessing curative effect of TCM for liver disease is practical and repeatable. It will be worthy of further evaluation and promotion to clinical application.

Purpose To explore the influence of duration of scan acquisition on perfusion parameters in whole renal perfusion with Revolution CT.Materials and Methods Fortytwo patients without pathologic changes in bilateral kidneys were divided into group A (with short perfusion time) and group B (with long perfusion time) according to the duration time of the perfusion scan.The Revolution CT axial scan mode was used for perfusion scan,and the width of detector was 16 cm.The perfusion CT series were performed in 50 seconds,each comprising 25 volumes with identical parameters (80 kVp,200 mA) in group A.The perfusion CT series were performed in 594 seconds,each comprising 23 volumes with identical parameters (120 kVp,55 mA) in group B.The source datasets were post-processed with CT Perfusion 4D software,and the perfusion parameter maps were obtained when right renal abdominal aorta was taken as entry artery.Perfusion parameters of bilateral kidneys were compared within and between group A and group B,respectively.CT dosage index of volume (CTDIvol) and dose length product (DLP) were recorded.The effective dose (ED) was calculated and compared.Results There were no statistical difference in all parameters between bilateral kidneys within each group (P＞0.05).However,blood volume,time to peak,and permeability surface in the cortex and medulla of bilateral kidneys all showed differences between the above two groups (P＜0.05).The mean transit time in the medulla between the two groups was different (P＜0.05),but neither the blood flow in the medulla and cortex nor the mean transit time of the cortex had difference between the two groups (P＞0.05).The effective radiation doses were (23.10± 4.39)mSv in group A and (23.19±0.00) mSv in group B,respectively (without statistic difference:P＞0.05).Conclusion CT perfusion parameters with different duration time show differences in whole renal perfusion;therefore,scanning time needs to be set according to the clinical application.
