Objective .To evaluate the role of cystatin c in the risk judgement of coronary artery disease. Methods 77 patients with coronary artery disease were involved in the study.They were divided into two groups:Group 1 were patients with angiographically diagnosed coronary artery disease ( CAD) with their first acute coronary syndrome ( n=55);Group 2 were patients who had clinically diagnosed coronary disease but were negative on angiog-raphy ( n=22) .Serum Cys C levels in the two groups and the correlation to CAD were analyzed.Results Serum Cys C levels in patients of Group 1 were higher than that of Group 2 [(1.23 ±1.07)mg/L vs.(0.71 ±0.32)mg/L,P=0.002],but no significant difference was found between the two groups in crea levels [(123.76 ±80.44)μmmol/L vs.(117.63 ±65.43)μmmol/L,P=0.230].A ROC analysis revealed that there was a significantly higher risk of ACS above a cystatin c level of 0.875mg/mL (sensitivity:84.3%,specificity:38.8%).A similar analysis carried out for eGFR did not find any significant cut-off points above which risk of ACS was higher.Conclusion The data showed that a high level of cystatin c level is a risk factor for ACS.This could play an important role in the early diag-nosis and prevention of adverse cardiovascular events.

Objective To investigate the genotoxicity of heavy rare-earth holmium to bone-marrow cells of mice.Methods Kunming mice were randomly divided into six groups and were given holmium-trioxide-HCl by gavage at several doses of 0,10,20,40,80 and 160 mg/kg bw respectively one time a day for two days;other Kunming mice were randomly divided into 3 groups and holmium nitrate was given i.p.at doses of 10,40 and 80 mg/kg bw respectively one time a day for two days.24 hours after the last treatment,the bone-marrow cells of thighbone were collected for micronuclei analysis and single cell gel electrophoresis (SCGE).Results Frequencies of micronuclei were increased by the 2 kinds of holmium solutions at the dosage from 10 to 80 mg/kg bw with a dose-effect relationship,but at the dose of 160 mg/kg bw,it was lower than the negative control.In SCGE,the average tail length increased significantly (P

Animal models are of great value in the study of allergic bronchial asthma.There are a varie-ty of methods to build asthma models,and model evaluation lacks standardized criteria.By retrieval analyzing the recent articles about asthma animal experiments at home and abroad,we conduct a comprehensive assessment on the experimental animal selection,model preparation,especially establishment and evaluation of ovalbumin-in-duced models,to help on the application and optimization about asthma models.

Objective To analyze the factors affecting the development of genome technology-based genetic testing services. Methods Purposive sampling was used to select experts in the field of genome or genetic testing. Following interview with 11 experts,data was obtained from 25 individuals and analyzed by using quantitative SWOT analysis, including the concept of SWOT method, Analytic Hierarchy Process,Internal Factor Evaluation ( IFE ) Matrix, and External Factor Evaluation ( EFE ) Matrix. Consistent ratio (CR) was chosen to test the logic. Results Of the 15 critical affecting factors, the weighting coefficient of deficiency of laws and market regulations, state supporting policies, and lack of intellectual property protection was 0. 099,0. 091 and 0. 087, respectively. The development of genetic testing services was found in the third quadrant of SWOT analysis. Conclusion These findings suggest that defensive strategy should be taken to improve genetic testing services and to reduce the risk of genetic testing.

Objective To analyze the relationship between insulin resistance (IR) and left ventricular hypertrophy ( LVH ) in patients with early chronic kidney disease ( CKD ). Methods Homeostatic model method was used for detecting insulin resistance index (Homa-IR) in 108 patients with early CKD and 25 normal healthy cases, and the other clinical data such as Hb, creatinine clearance rate (Ccr) , parathyroid hormone (PTH) , ambulatory blood pressure monitoring ( ABPM ) data, including day average systolic blood pressure (dSBP), day average diastolic blood pressure (dDBP), night average systolic blood pressure ( nSBP) , night average diastolic blood pressure ( nDBP) , 24-hour mean systolic blood pressure (mSBP), 24-hour mean diastolic blood pressure (mDBP), decline in the percentage of diastolic blood pressure at night (nDPD) and decline in the percentage of systolic blood pressure at night (nDPS) were also measured. Echocardiography was used for measuring LVH relevant data, and left ventricular mass index (LVMI) was calculated. Then, the relationship between LVH and IR and other clinical data were analyzed retrospectively. Results IR existed in early CKD patients. With the decline of Ccr, both the value of Homa-IR and the incidence of IR increased significantly (both P < 0. 05). LVH existed in early CKD patients and with the decline of Ccr, both LVMI value and the incidence of LVH increased significantly (both P <0. 01). Compared with the non-IR group, the IR group had higher LVMI value (P<0. 05) and higher incidence of LVH (P<0. 01). Compared with the non-LVH group, the LVH group had higher levels of Fins, 2hPG, Homa-IR (all P <0. 05), and higher incidence of IR (P <0. 01). The LVH group had significant lower levels of Ccr, Hb and nDPD (all P <0. 05) , higher levels of dSBP, dDBP, nSBP, nDBP, mSBP, mDBP and PTH (all P<0.05) than the non-LVH group. LVMI had significant positive correlations with 2hPG, Fins, Homa-IR, dSBP, nSBP, mSBP and PTH (r = 0.255, 0.373, 0.376,0.222,0.199,0.225,0.221,0.246, respectively; all P<0.05), but significant negative correlations with Hb and Ccr (r = -0.588,-0.313, respectively; both P<0.01). Multi-factor regression analysis showed that Hb, Homa-IR, and Ccr entered the regression equation (y = 167. 106 - 0. 755x_1 + 0. 250x_2 +0.322x_3, y = LVMI; 167. 106 = constant, t = 12. 138, P =0.000; x_1 =Hb, t= -6.800, P = 0. 000; x_2 = Homa-IR, t = 3. 229, P = 0. 002; x_3 = Ccr, t = 2. 898, P = 0. 005). Conclusion IR existed in early CKD patients and become more severe with the decline of renal function. IR had a significant correlation with LVH, and it may be an important risk factor for the development of LVH. Besides, both anemia and decline of renal function are also associated with LVH.

Lipocalin-2 is an adipocytokine secreted mainly by adipose tissue. Increasing lines of evidence suggest that lipocalin-2 is an inflammatory factor associated with insulin resistence, obesity and its complications. The precise mechanism of the development of obesity-related disorders induced by lipocalin-2 is not very clear, however, it may be a useful target in drug therapy for obesity-related metabolic and cardiovascular diseases.
