Diabetes can affect structure and function of brain in several aspects, but diabetic cognitive impairment is often ignored. The pathogenesis of diabetes associated cognitive impairment is complicated. Factors such as glucotoxicity, lipotoxicity, insulin resistance, hypoglycaemia and disturbance of Ca2 homeostasis may play important roles. Besides conventional diabetes therapy, new methods still need to be explored.

Objective To investigate the prevalence of anti-HCV positive among volunteer blood donors in Zhouk-ou city. Methods A total of 200 950 blood specimens from voluntary blood donors in Zhoukou from 2007 to 2012 were detected for anti-HCV by double-antibody sandwich enzyme-linked immunosorbent assay,results were ana-lyzed. Results The total positive rate of anti-HCV was 0.21% (416/200 950),there were significant difference in positive rates of anti-HCV among populations of different genders,ages and educational background(χ2= 24.01 , 142.31,45.8,respectively,allP<0.01),the positive rate of anti-HCV in female was higher than that of male ([0.27% ,205/75 658]vs [0.17% ,211/125 292]);the positive rate of anti-HCV was the lowest in donors aged 21-30 years (0.06% ,38/63 719),and highest in donors aged>40 years (0.33% ,162/48 871);the lower donors re-ceived education,the higher positive rate of anti-HCV they had,the positive rate of anti-HCV in donors with j unior high school education was 0.26% (107/41 154). The positive rate of anti-HCV in blood donors decreased gradually from 2007 to 2012(χ2= 14.576,P<0.05).Conclusion The positive rate of anti-HCV is low in voluntary blood do-nors in Zhoukou and is significantly different among different populations.

Objective To evaluate the relationship of the levels of serum oxide and antioxide with endothelium-dependent vasodilatation(EDV) in obese subjects and to explore the effect of oxidative stress on endothelial dysfunction in obese subjects. Methods 20 euglycemic obese males (Ob) and 13 age- matched normal controls (NC) underwent euglycemic hyperinsulinemia clamp study to evaluate the peripheral glucose disposal rate (GDR) in steady-state and brachial artery ultrasound studies to assess the endothelium-dependent vasodilatation (EDV). The serum levels of ROS, MDA, GSH-PX, GSH and free fatty acids (FFAs) were measured. Results The serum ROS, MDA and FFA concentrations were significantly higher in Ob group than in the controls (P

Objective To study and observe the change of nerve function and erythrocyte immune indexes of patients with severe craniocerebral injury during the perioperative period.Methods Forty patients with severe craniocerebral injury treated with surgery in our hospital from July 2013 to August 2015 were selected as the observation group and 40 healthy persons with the same ages in the same period were selected as the control group.The nerve function related indexes and erythrocyte immune indexes of observation group before and at first,third,fifth,seventh,tenth and fourteenth day after the surgery and those of control group were compared.Results The serum nerve function related indexes of observation group before and at first,third,fifth,seventh,tenth and fourteenth day after the surgery were higher than those of control group.The erythrocyte immune indexes of observation group before and at first,third,fifth,seventh and tenth day after the surgery were worse than those of control group.The erythrocyte immune indexes at fifth and seventh day after the surgery were worse than those before and at first,third,third,tenth and fourteenth day after the surgery.The differences of comparison indexes were all significant (P＜0.05).Conclusion The change of nerve function and erythrocyte immune indexes of patients with severe craniocerebral injury during the perioperative period are obvious.Those indexes should be paid with enough monitoring and intervention.

Objective To explore the reliability of acute physiology and chronic health evaluation Ⅱ(APACHE Ⅱ)to evaluate the severity of the neurologic diseases and its accuracy to predict the outcome of patients with these diseases.Metllods Four hundred and four consecutive patients with severe neurologic diseases between 2005 and 2006 were enrolled to obtain the APACHE Ⅱ scores at 0.24,48,72 h after admission to neurointensive care unit.Results The APACHE Ⅱ scores were positively associated with the outcome of the patients with severe neurologic diseases.The higher score corresponded with the higher mortality rate.The areas under the receiver operating characteristic curves of APACHE Ⅱ to predict the outcome was 0.866(95% CI 0.824 to 0.907.P=0.000).The optimal cutoff of APACHE Ⅱ scores to predict the outcome was 17 scores with the sensitivity of 76.7%and the specificity of 78.7%.The predictive chance that was mostly associated with the outcome was 72 h after admission in logistic regression model (x2=137.345,P=0.000,correct class%=85%).The factors that were the most statistically associated with the outcome in the 14 parameters of APACHE Ⅱ were GCS score,heart rate,serum creatinine,body temperature and WBC count.Conelusion APACHE Ⅱ favorably reflects the severity of the neurologic diseases and reliably and accurately predicts the prognosis of the patients.

Purpose: Through meta-analysis, we aimed to assess the efficacy and safety of drug-coated balloons (DCB), compared with drugeluting stents (DES) or uncoated devices, in the treatment of de novo coronary lesions. Materials and Methods: Only randomized controlled trials were included. The primary outcomes were late lumen loss (LLL), target lesion revascularization (TLR), and major adverse cardiac events (MACEs). Subgroup analyses were conducted based on clinical indications, whether DCBs were used with a systematic or bailout stent, and types of DESs. Results: The present meta-analysis demonstrated that DCBs elicit significantly lower incidences of TLR, MACE, and LLL, compared with uncoated devices, and similar incidences, compared with DESs, in the treatment of de novo coronary lesions. Subgroup analysis indicated that DCBs used with a bailout stent achieved lower incidences of binary restenosis and myocardial infarction, compared with uncoated devices, and provided less LLL than DESs. DCBs showed similar rates of TLR and MACE, with significantly less LLL, than DESs in treating de novo small-vessel diseases. The clinical efficacy of DCBs was similar to that of secondgeneration DES. Conclusion Overall, DCB is favored over bare metal stent alone in treating de novo coronary lesions. DCBs appear to be a promising alternative to DESs in the treatment of de novo coronary lesions.
