Objective To evaluate the significance of color Doppler ultrasound examination of renal blood flow combined with the detection of bone morphogenetic protein-7(BMP-7)in early diagnosis of type 2 diabetic nephropathy.Methods Blood BMP-7 level was tested in 90 patients with type 2 diabetic nephropathy and 30 controls,and parameters of renal blood flow were measured by color Doppler ultrasound examination.Blood BMP-7 level as well as resistant index(RI)of segmental renal artery(SRA)and interlobar renal artery(IRA),were compared between these two groups.Results Compared with controls,blood BMP-7 level gradually decreased with the aggravation of diabetic kidney damage(P＜0.01).The peak systolic velocity(Vmax)and the end diastolic velocity(Vmin)of SRA and TRA were slowed gradually,while RI increased(P＜0.01).Blood BMP-7 level was negatively correlated with IRA's and SRA's RI of IRA and SRA(r =-0.603,P＜0.01;r =-0.652,P＜0.01).Conclusions Color Doppler ultrasound examination of renal blood flow combined with detection of BMP-7 might play an important role in early diagnosis of type 2 diabetic nephropathy.

Objective To investigate the metabolic characteristics,clinic values of different tissues in benign prostatic hyperplasia by correlating MR spectroscopy(MRS)with whole pathologic sections.Methods MRS presentation was studied in 16 patients with benign prostatic hyperphsia.The peak values of citrate,choline and creatine were measured,and the mtios of(choline+creatine)/citrate(cc/c)were obtained.After suprapubic transvesical prostatectomy,the specimens of whole pathologic sections were observed.The values of cc/c of different pathologic types were compared statistically with One.way-ANOVA and t test. Results MRS results were obtained in 578 units,which included 233 glandular tissue units.130 matrical tissue units.165 mixed tissue units and 50 tissue units around urethra.The ratios of (choline+creatine)/citrate of glandular,matrical.mixed tissues and units around urethra were 0.59±0.29.1.23±0.38.0.80±0.27 and 0.68±0.33(F=3.49.P＜0.05).The t tests were carried out between every two tissues.The t valUes between glandular tissues and matrical.mixed tissues were 19.60 and 7.09.P＜0.05:the t values between matrical tissues and mixed tissues.units around urethra were 13.22 and 9.42,P＜0.05;the t valUes between mixed tissues and units around urethra was 9.42,P＜0.05.Condusions,The ratios of cc/c ofthree prostate tissues were different in MRS.The metabolic characteristic of the units around urethra Was near to glandular units.MRS may be valuable to the distinctive diagnoses of prostate diseases.

Objective To investigate the detection rate of abnormal cardiovascular and metabolic indicators in health check-up populations,and provide evidence for early screening and health interventions for cardiovascular and metabolic diseases.Methods A total of 5578 adults (male 3404 and female 2174) were recruited from a medical institution in Beijing in 2008 and 2010.Cardiovascular and metabolic indicators,including blood pressure,lipid profile and fasting plasma glucose,were tested at baseline and 2 years.Paired t test or paired rank sum test was used for data analysis.Results Detection rate of abnormal blood pressure in 2010 was lower than that in 2008; however,rates of abnormal total cholesterol,low-density lipoprotein cholesterol and fasting plasma glucose were higher in 2010 than in 2008 (t values were 5.378,13.885,3.210,10.401 and 4.355,respectively; all P ＜ 0.05).High-density lipoprotein cholesterol and triglyceride showed no statistically significant difference between 2008 and 2010 (t values were 1.204 and -0.012,respectively; both P ＞ 0.05).Conclusion We have been observing a dynamic change in abnormal cardiovascular and metabolic indicators,based on which effective interventions could be taken to reduce the risk of cardiovascular diseases.

Objective To study the default mode network (DMN) of mild cognitive impairment (MCI) related to leukoaraiosis (LA) with resting-state functional magnetic resonance imaging (rs-fMRI). Methods 31 LA patients (Clinical Dementia Rating of 0.5) and 27 normal controls (Clinical Dementia Rating of 0, and matched in age, gender and lever of education) were scanned with the rs-fMRI. The data was analyzed with SPM5 software, using independent component analysis. The differences between the both groups were compared with two-sample t-test. Results The DMN during resting-state of normal controls was posterior cingulate cortex/precuneus, bilateral medial frontal cortex, bilateral middle temporal gyrus, bilateral inferior parietal gyrus, angular gyrus, bilateral hippocampus. The DMN of MCI group was consistent with the normal controls, but the activation decreased in anterior cingulate cortex/left medial frontal lobe, right parahippcampus/ uncus, right inferior temporal gyrus, left deep frontal white matter/head of caudate nucleus; and increased in the left caudate nucleus/anterior cingulate cortex, left frontal lobe, and left superior temporal gyrus/inferior parietal gyrus. Conclusion Activation of resting-state functional network is disorder in LA, which may relate to cognitive impairment.

Objective To study the changes of plasma endotoxin and procalcitonin in patients with esophagogastric varices and provide a theoretical basis for prophylactic antibiotics after endoscopic treatment. Methods Fifty cases of patients with esophageal and gastric varices accepted the endoscopic treatment.The patients were divided into antibiotic group (32 cases)and non-antibiotic group (18 cases).The plasma endotoxin and procalcitonin were measured before and on the first day and 7th day after endoscopic treatment.Results The plasma levels of endotoxin and procalcitonin were not significantly different on the first and 7th day after endoscopic treatment compared with preoperative levels in antibiotic group.But in non-antibiotic group,the levels significantly increased on 7th day after endoscopic treatment compared with preoperative levels (P <0.05).And in patients of Child-Pugh A grade,the level of plasma procalcitonin significantly increased on 7th day after endoscopic treatment compared with preoperative levels (P <0.01), but the procalcitonin was not significantly different on the first and 7th day after operation.And in patients of Child-Pugh B and C grades,the levels of plasma endotoxin and procalcitonin significantly increased on the 7th day(P <0.01).Conclusion The levels of plasma endotoxin and procalcitonin in non-antibiotic group increase after endoscopic treatment,which suggests the risk of infection.Prophylactic antibiotics after endo-scopic treatment should be considered for the patients of Child-Pugh B and C grades.
