OBJECTIVE To investigate the characters of urinary noscomial infection in intensive care unit(ICU)of our hospital in order to reduce its incidence. METHODS The 661 patients in ICU of our hospital from Jan 2005 to Jun 2006 were analyzed,and in which 63 nosocomial urinary infection patients(9.53%) were found.We analyzed the 63 patients retrospectively. RESULTS Nosocomial urinary infection occurred in 9.53% patients admitted to the ICU.Nosocomial urinary infection in ICU was correlated with ages,using of antibiotics and hormones,duration of catheterization and APACHEⅡ score,but not with gender.The most prevalent pathogens of nosocomial urinary infection in ICU were fungi(40.66%),gram-negative bacteria(31.87%) and Gram-positive bacteria(27.46%).The clinical manifestation of nosocomial urinary infection in ICU was atypical. CONCLUSIONS Nosocomial urinary infection in ICU has its own characters which clinicians should pay more attention to.To reduce its incidence,we should avoid abusing of antibiotics and hormones,and make the duration of catheterization as short as possible.

Objective To study the clinical significance of the change of plasma BNP levels in patients with grades sepsis and its correlation with the left ventricular ejection fraction.Methods One hundred patients of sepsis who were admitted in intensive care unit of Taizhou hospital were selected.It was divided into four groups:30 patients with septic shock,40 patients with severe sepsis,30 patients with sepsis and 20 persons without disease as control group.The concentration of plasma BNP was determined using sandwich immunoflurescence,and ultrasonic cardiogram was used to evaluate heart function and clinical features in all groups.To compare with the differences of the concentration of plasma BNP and the correlation between the concentration of Plasma BNP and LVEF in all groups,the data of clinical features,28-day mortality,prognostic values of BNP and the length of stay (ROG) in ICU were collected and compared.Result Plasma BNP levels in patients with septic shock[ (976.3 ± 160.7) pg/ml] were obvious higher than severe sepsis[ (648.4 ± 267.3) pg/ml ],sepsis [ (217.2 ± 89.7) pg/ml ] and control group [ (50.3 ± 25.4)pg/ml] (P ＜0.01).LVEF in patients with septic shock [ (48.2 ±9.6)% ] was obvious lower than severe sepsis[ (52.8 ±9.4)% ],sepsis[ (61.3 ± 8.9)% ] and control group[ (66.4 ±9.3)% ] (P ＜0.05 or P ＜0.01).It appeared to be inverse relationship between LVEF and the plasma BNP levels (r =-0.876,-0.724,P ＜0.01).BNP levels were significantly higher in non-survivors compared with survivors[ (1367.6±506.4)pg/ml vs (420.3 ±82.6)pg/ml,P ＜0.01 ].The receiver operating characteristic (ROG) curves indicated that values of areas under the curve of plasma BNP levels for 28-days mortality were 0.918(P ＜0.01).Conclusion The concentration of plasma BNP in patients was different in different grades of sepsis.It appeared to be negative correlation between the concentration of plasma BNP and LVEF.Plasma BNP levels had predictive value to the patients with sepsis.

Objective To investigate the effect of different enteral nutrition (EN) preparations on nutritional status and glucose metabolism in elderly heart failure (HF) patients. Methods Eighty-two elderly HF patients were consecutively admitted to Taizhou Enze Medical Center Group Enze Hospital from January 2017 to March 2018, and they were randomly divided into a study group and a control group, each group with 41 cases. The basic treatments were the same in two groups, while the patients in study group were treated with TPF-D emulsion, and those of control group were treated with SP emulsion. Nutritional status [serum albumin (Alb), proalbumin (PA) and transferrin (TF)], glucose metabolism indexes (glucose, Betatrophin and insulin dose), cardiac function [N-terminal B-type pro-brain natriuretic peptide (NT-proBNP), left ventricular ejection fraction (LVEF)], high-sensitivity C-reactive protein (hs-CRP) in serum were compared between two groups after treatment, and the incidences of adverse reactions (gastric retention, diarrhea, constipation, electrolyte abnormality, pulmonary infection, dysfunction of liver) were also observed in the two groups. Results In the aspect of nutrition, no statistical significant differences in indexes were found at each time point between the two groups during the therapeutic course (all P > 0.05). In terms of glucose metabolism, the blood glucose levels in the study group were significantly lower than those in the control group on day 5 and day 7 after treatment (mmol/L: 9.73±3.69 vs. 11.56±3.78 on day 5, 8.35±2.17 vs. 10.41±2.38 on day 7, both P < 0.05); the serum Betatrophin levels in the study group were also significantly lower than those in the control group on 5 days and 7 days (μg/L: 5 days was 1.36±0.49 vs. 1.89±0.74, 7 days was 1.31±0.47 vs. 1.62±0.59, both P < 0.05); the doses of insulin used in the study group were obviously lower than those in the control group on 3, 5 and 7 days (U: 3 days was 37.86±8.49 vs. 47.84±10.33, 5 days was 29.33±7.45 vs. 38.56±9.69, 7 days was 13.35±8.56 vs. 28.49±9.77, all P < 0.05). In terms of cardiac function, the study group showed significant lower NT-proBNP levels on 3, 5 and 7 days (μg/L: 3 days was 5.8±0.8 vs. 6.2±1.0, 5 days was 3.7±0.7 vs. 4.4±0.9, 7 days was 1.9±0.5 vs. 3.1±0.7, all P <0.05]; significant higher level of LVEF in study group on 7 days (0.50±0.02 vs. 0.48±0.03, P < 0.05) and significant lower hs-CRP levels in study group on 5 days and 7 days (μg/L: 5 days was 27.12±10.58 vs. 34.41±12.69, 7 days was 15.33±9.87 vs. 22.71±11.45, both P < 0.05). In addition, compared with the control group, the incidence of gastric retention [17.07% (7/41) vs. 36.59% (15/41)], so of diarrhea [14.63% (6/41) vs. 34.15% (14/41)] and of electrolyte abnormalities [14.63% (6/41) vs. 39.02% (16/41)] were significantly lower in study group than those in the control group (all P <0.05). Conclusion Compared with SP, TPF-D not only can effectively improve the nutritional status, but also can superiorly control blood glucose, improve cardiac function and lower the incidence of adverse reactions in elderly HF patients.
