Objective To investigate the prevalence of chronic kidney disease (CKD) and its risk factors in Chinese elderly persons.Methods All of the people who underwent physical examination and treatment in the geriatric department of Beijing Hospital during January 2004 to January 2007 were included in the study.Age, body height, body mass index and blood pressure were recorded.Bloody urine was ascertained by phase-contrast microscope, and urine protein was measured by dipstick test.The hemoglobulin, serum eretinine, blood urea nitrogen, blood lipid and serum uric acid were measured by autobiochemical analyzer.HbsAg was checked by enzyme-linked immunosorbent assay (ELISA).Glomerular filtration rate (GFR) was estimated by Crockeroft-Gauh equation and abbreviated MDRD equation.Binary logistic regression analysis was used to test the risk factors for proteinuria and CKD.Results The prevalence of proteinuria was 4.9% in 1082 elderly persons.And 47.23% of the elderly suffered from decreased renal function.The morbidity of CKD was 48.43%.Binary logistic regression analysis showed that diabetes(OR= 2.257) and microscopic hematuria(OR=5.324) were the risk factors of proteinuria (both P<0.05).And the risk factors for CKD were hypertension(OR= 1.459), coronary arth'erosclerotic heart disease(OR=3.290), chronic obstructive lung diseases(OR=2.094), malignant tumor(OR=2.072), hyperuricemia(OR= 1.928),anemia(OR=8.122)and hematuria( OR= 1.604) (all P<0.05).Conclusions The morbidity of CKD in Chinese elderly persons was 48.43%.And the related risk factors were diabetes,hypertension, hyperuricemia, coronary artherosclerotic heart disease and chronic obstructive lung disease.
RESUMEN
Objective To observe the changes of serum soluble CD40 ligand (sCD40L) and fibrinogen in acute myocardial infarction (AMI) patients and to investigate the clinical predictive value of increased serum sCD40L and fibrinogen. Methods Serum sCD40L level of 60 AMI patients was determined by enzyme-linked im-munosorbent assay (ELISA). Plasma level of fibrinogen was measured. The patients were followed up for 2 years af-ter discharge from the hospital and were observed for cardiovascular event. Results AMI patients had higher sCD40L and fibrinogen levels than those of controls [(15.36±7.32) μg/L vs. (5.79±2.78) μg/L, (4.60±1.37)g/L vs. (3.03±0.82) g/L,P<0.001] ,which were significantly higher in the patients experiencing cardio-vascular event than those without cardiovascular event [(18.14±6.34) μg/L vs. (14.38±6.67) μg/L and (4.97±1.33)g/L vs. (4.20±1.24} g/L] (P<0.05). The patients with sCD40L≥14.5 μg/L or fibrinogen≥ 4.4 g/L experienced increased risk of adverse cardiovascular events (P<0.05). In AMI patients, sCD40L level was significantly higher in patients with diabetes than in nondiabetics [(18.38±6.71) μg/L vs. (14.46±6.48) μg/L, P<0.05)]. Fibrinogen level was related to sCD40L (r=0.27, P<0.05) and LVEF(r=-0.319, P<0.05). Conclusion Increased sCD40L and fibrinogen levels,which maybe related to the pathogenesis of AMI,can be found in AMI patients and can indicate an independent increased risk of major adverse cardiovascular events. Diabetes is independently associated with elevated sCD40L level in AMI patients.

Objective To evaluate the direct economic costs of four major kinds of nosocomial infections such as nosocomial pneumonia,urinary tract infection, deep surgical wound infection and intracranial infection. Methods A matched case-control study was conducted among 95 pairs of hospitalized patients to investigate the direct economic costs of nosocomial infections. Results The average medical cost for patients in the case group was 38 741 RMB Yuan, 20 365 Yuan more than that in the control group patients (P＜0.000 1). The largest part of extra costs was found in drug expenses, taking up 62.07%, while other extra costs such as non-drug therapies, blood transmission and laboratory examinations, accounted for 10.32%, 7.40% and 5.72% respectively. Extra economic burden caused by nosocomial infections varied in different degrees with different departments, with the heaviest found in the department of tumourology and hematology at an average extra cost of 34 944 Yuan. The average extra charges in case group caused by nosocomial pneumonia,urinary tract infection, deep surgical wound infection and intracranial infection were 31 940 Yuan,7 436 Yuan,17 332 Yuan and 17 349 Yuan respectively. The average length of hospital stay was 50.57 days in case group and 25.22 days in control group, showing a 25.53 extra days (P＜0.000 1) of hospitalization due to nosocomial infections. Conclusion Nosocomial infections had significantly added to the economic burden of managing the underlying diseases, led to prolonged hospitalization of the patients and lowered the turnover rate of hospital bed. There is a need to call for better infection control program, which would bring tremendous social and economic profits.

ObjectiveTo investigate the visual condition and causes of blindness and low vision of ov er 60 years old people found by routine physical examination. Methods A total of 892 cases over 60 years old people took a yearly routine examinatio n, such as far and near vision in daily life, anterior segment and fundus of the eye and intraocular pressure. If the vision were under 0 3, the refractive vis ion needs to be corrected. The blindness and low vision patients were selected a nd taken further related examinations to analyse statistically the causes of bli ndness. Results Among 892 cases investigated, blindness together with low vision were 42 cases (4 71%). The morbidity rate of blindness and low vision were 1 01% (9 cases) a nd 3 70% (33 cases) respectively. Diseases caused blindness were macular lesio ns (57 14%), glaucoma(11 91%), cataract (9 52%), retinal diseases, optic nerv e atrophy, keratopathy etc. Refractory eye diseases were obviously more than t he eye diseases which can be treated. The morbidity rate of over 80 years old pe ople were obviously more than that of under 80 years group. Conclusions With ageing, the old people easily suffer from eye diseases and results in bli ndness. For the prevention and treatment of blindness for the elderly, much atte ntion to treatment of eye diseases should not only paid, active training is also important.
