Objective To explore the correlation between serum uric acid(SUA) level and Alzheimer's disease(AD) in elderly patients. Methods 67 cases of the elders with Alzheimer's disease and 160 elders matching with age and gender were enrolled from Jan 2013 to Dec 2014 in the study,the blood levels of biochemical factors such as SUA,total cholesterol(TC),triglycerides(TG),low-density lipoprotein cholesterol(LDL-C),high-density lipoprotein cholesterol(HDL-C),fasting blood sugar(FBS) and creatinine(Cr) were measured by automatic biochemistry analyzer in the two groups. The related factors such as history of disease,smoking and medication history were collected. The correlation between the level of SUA and AD was analyzed. Results The serum uric acid levels in AD group were significantly lower than those in control group(P＜0.01). Multivariate logistic regression analysis showed that age, gender, ischemic stroke were risk factors, and taking statin, SUA, and HDL-C were protective factors(P＜0.05). Spearman correlation tests indicated that there was an inverse correlation between SUA levels and AD(rs=-0.285,P<0.001). Conclusion Serum uric acid level is significantly related to AD in the elderly.SUA may be a protective factor of the occurrence of AD.

Objective To analyze pathogens and risk factors of VAP in a general ICU of a primary hospital. Methods Totally 112 patients(from 2013-01 to 2014-12) under mechanical ventilation over 48 h were retrospectively studied. The patients were assigned into VAP group and non-VAP group. The independent risk factors and pathogens of VAP were analyzed. Results There was significant difference between VAP group and non-VAP group in terms of emergent tracheal intubation, MV time, types of antibiotics used, the use of hormones,the use of PPI and sedative drugs for more than 7 days, regurgitation, MODS, ICU stay time. Emergent tracheal intubation:52.2％ vs 31.9％,P＝0.029;MV time:9.8±3.5day vs 7.3±2.8day,P＝0.038;types of antibiotics used > 2 kinds:52.2％ vs 26.4％,P＝0.005;the use of hormones:56.5％ vs 27.0％,P＝0.001;the use of PPI >7day:65.2％ vs 40.3％,P＝0.008;the use of sedative drugs >7day:58.7％ vs 38.9％,P＝0.035;regurgitation:50％ vs 29.2％,P＝0.022;MODS:47.8％ vs 22.2％,P＝0.004;ICU stay time:13.6±6.6day vs 10.2±5.3day,P＝0.023. The use of hormones,MV time, ICU stay time were the independent risk factors of VAP[odds ratio(OR) of multivariate logistic regression:2.481、1.234、1.075]. The main pathogens of VAP were gram-negative bacteria (82.3%). Conclusion The study shows that the use of hormones,MV time, ICU stay time are the independent risk factors of VAP; gram-negative bacteria are the main pathogens of VAP. Once VAP occurs, they can be treated with anti-gram-negative bacteria antibiotics.
