Methods : According to the diagnostic standard of coronary artery angiography,116 patients were divided into CAD group (82 patients) and nonCAD group (34 patients). The albumin and creatinine concentrationratio ratio(ACR) in morning urine samples from patients of both groups was estimated and compared. The correlation of ACR to the extent of coronary lesions was analyzed. Results : ACR in the CAD group was significantly higher than that in nonCAD group. A distinctly linear positive correlation existed between ACR and the score of the coronary lesions. Conclusion : ACR increase in patients with CHD.Micoalbuminuria was associated with the severity of coronary lesions in patients with CHD and is an independent predictor of CAD.
Objective To investigate the effect of a real-time compliance dashboard to help reduce ventilator-associated pneumonia ( VAP) with ventilator bundle. Methods 240 patients who were admitted into the intensive care unit ( ICU) of Shougang Hospital of Peking University and had received mechanical ventilation ( MV) for over 48 hours, between January 2010 and November 2011, were studied prospectively. The patients were divided into two groups by random number table, ie. a dashboard group ( n = 120) with implementation of a real-time compliance dashboard to help reduce VAP with ventilator bundle, and a control group ( n=120) with implementation of usually routine order to help reduce VAP with ventilator bundle. The success rate of ventilator bundle implementation, incidence of VAP, duration of MV, duration within ICU, mortality within 28 days, cost within ICU were compared between two groups. Results Compared with the control group, the success rate of ventilator bundle implementation obviously increased ( 81.6% vs. 52.5%) , incidence of VAP ( 14. 5/1000 days of MV vs. 36.2 /1000 days of MV) , duration of MV [ 5( 4,7) days vs. 8( 6,11) days] , duration within ICU [ 8( 6,12) days vs. 13( 8,16) days] , mortality of 28 days ( 12.6% vs. 28.6% ) , and cost within ICU ( 36,437 vs. 58,942) in the dashboard group obviously reduced ( Plt;0.05) . Conclusions Implementation of a real time compliance dashboard to help reduce VAP with ventilator bundle can obviously improve medical personnel compliance and reduce incidence of VAP, duration of MV, duration within ICU, mortality and cost in ICU than those of routine medical order to help reduce VAP with ventilator bundle.
ObjectiveTo study the effects of visceral adipose tissue area (VTA) and subcutaneous adipose tissue area (STA) on pulmonary ventilation function (PVF), and then to evaluate the impact of abdominal fat distribution on PVF.Methods Patients who underwent both PVF examination and abdominal CT between January 1st and December 31st, 2017 were selected from the electronic medical record system of West China Hospital of Sichuan University. The demographic data and PVF indexes [vital capacity (VC), forced vital capacity (FVC), forced expiratory volume in one second (FEV1), and 1 s rate (FEV1/FVC)] were collected. VTA and STA were obtained by abdominal CT measurement. The correlations between PVF indexes and VTA or STA were compared. Results A total of 224 patients were included. According to the VTA/STA ratio, there were 92 cases (41.07%) in group VTA/STA<1 and 132 cases (58.93%) in group VTA/STA≥1. VTA was not correlated with FVC (rs=−0.078, P=0.244), but negatively correlated with VC (rs=−0.138, P=0.040), FEV1 (rs=−0.141, P=0.034) and FEV1/FVC (rs=−0.137, P=0.041); STA had no correlation with VC, FVC, FEV1 or FEV1/FVC (P>0.05). VTA/STA was negatively correlated with VC (rs=−0.220, P=0.001), FEV1 (rs=−0.273, P<0.001) and FEV1/FVC (rs=−0.380, P<0.001), but it had no correlation with FVC (rs=−0.083, P=0.214). In group VTA/STA<1, VTA/STA was negatively correlated with FEV1 (rs =−0.205, P=0.050) and FEV1/FVC (rs=−0.317, P=0.002), but it had no correlation with VC or FVC (P>0.05). In group VTA/STA≥1, VTA/STA was negatively correlated with VC, FVC, FEV1 and FEV1/FVC (P<0.05). Conclusions VTA and STA are negatively correlated with PVF. The ratio of VTA/STA can be used as an index to evaluate the effect of abdominal fat distribution on lung function.
ObjectiveTo investigate the incidence, pathogens, risk factors and clinical outcomes for ventilator- associated pneumonia (VAP) in children after tetralogy of Fallot (TOF) surgical correction, in order to offer reliable data for the prevention of VAP.MethodsThis was a retrospective study performed in Guangdong General Hospital and 181 children (121 males, 60 females, mean age of 11.2±10.4 months) undergoing surgical correction for TOF were included. ALL the children who received mechanical ventilation for 48 hours or longer between January 2013 and December 2017 were classified into a VAP group (n=44) and a non-VAP group (n=137). T test, χ2 test and multiple logistic regression analysis were used to identify the possible risk factors for VAP.ResultsThis study enrolled 181 patients , of which 44 were diagnosed as VAP. And the incidence of VAP was 24.3%. The most frequent isolated pathogen was Gram-negative bacteria (69.7%). Single factor analysis showed that the variables significantly associated with a risk factor of VAP were: hypoxic spells, preoperative pneumonia, preoperative mechanical ventilation support, cardiopulmonary bypass (CPB) time, reintubation, pulmonary atelectasis, low cardiac output syndrome (LCOS), intra-abdominal drainage and transfusion of fresh frozen plasma. The multiple logistic regression showed CPB time (OR=1.011), reintubation (OR=14.548), pulmonary atelectasis (OR=6.139) and LCOS (OR=3.054) were independent risk factors for VAP in children after TOF surgical correction. Patients with VAP had prolonged duration of mechanical ventilation, a longer ICU stay and longer hospitalization time.ConclusionsThe VAP rate in this population is higher than that reported abroad, which leads to prolonged duration of mechanical ventilation and a longer hospital stay. The effective measures for prevention of VAP should be taken according to the related risk factors for VAP to decrease the incidence of VAP in children after TOF surgical correction.

Methods The blood lipid (TG, TC, LDL, and HDL) levels in 200 asymptomatic individuals with high uric acid (A group) and 200 sex-and age-matched ones with normal serum uric acid (B group) were examined and the results of the two groups were compared. Results The concentration of triacylglycerol, total cholesterol, low-density lipoprotein cholesterol, and high-density lipoprotein cholesterol were (3.09±0.98), (4.05±1.07), (3.38±0.98), and (1.30±0.51) mmol/L, respectively in group A; and were (1.65±0.86), (3.99±0.99), (2.97±0.89), and (1.41±0.66) mmol /L, respectively in group B. The concentration of TG in group A was obvious higher than that in group B (Plt;0.01). However, the differences of their total cholesterol, low-density lipoprotein cholesterol, and high-density lipoprotein cholesterol were not significant (Pgt;0.05). The increase of TG was obvious compared with TC(Plt;0.01), LDL (Plt;0.01), and HDL (Plt;0.01) in group A; while the comparisons in group B were not significant (Pgt;0.05). Conclusion Uric acid metabolism correlates with triacylglycerol metabolism.
Objective Secondary osteoporosis is very common in patients with primary osteoporosis. Diabetes is a known cause of secondary osteoporosis. While type I diabetes has been clearly linked with diabetic osteoporosis, the effect of type II diabetes on bone health is controversial.Methods In the present study, we investigated the associations between type II diabetes and osteoporosis as well as fractures at different skeletal sites in Women’s Health Initiative participants.Results Common risk factors such as age, race, BMI, HRT use, and the history of fractures were significantly associated with osteoporosis and fractures in this study population. Diabetic women appeared to have a decreased risk of osteoporosis although it no longer remained significant after adjusting for other risk factors (crude HR=0.78, 95%CI 0.61 to 0.99; adjusted HR=0.93, 95%CI 0.73 to 1.19). The impact of diabetes on fractures varied at different body sites. There was a significant increase of risk of hip fracture (HR=2.54, 95%CI 1.14 to 5.66), but not spine fracture (HR=1.71, 95%CI 0.81 to 3.60) and arm fracture (HR=0.92, 95%CI 0.48 to 1.76) among the women with diabetes. Although the overall risk of fractures in diabetic women did not differ significantly from non-diabetic women (HR=1.37, 95%CI 0.89 to 2.09), the difference had a two-fold increase and was statistically significant after 2,000 days (HR=2.01, 95%CI 1.21 to 3.35), indicating a different hazard at different stages of diabetes.Conclusion Our findings suggest that type II diabetes may not be clearly associated with osteoporosis, it increases a site-specific fracture risk at least in the hip. In addition, the overall fracture risk appears to increase in a time-dependent manner.
ObjectiveTo systematically review the correlation between adenoviral infection and encephalitis in children. MethodsStudies on the correlation between adenoviral infection and encephalitis among children were retrieved in the databases of CHKD, CNKI, WanFang Data, CMCC, PubMed, Ovid, EBSCO, and Science New during 1978-2013. According to our inclusion and exclusion criteria, literature was screened. After data extraction, meta-analysis was conducted using Comprehensive Meta Analysis 2.0. ResultsA total of 18 studies were enrolled. The results of meta-analysis indicated that:the prevalence of infection of human adenovirus in children with encephalitis was p1=10.8% (95%CI 6.5% to 15.2%, P < 0.000 01). The incidence of encephalitis in children with adenoviral infection was p2=31.4% (95%CI 14.1% to 48.6%, P < 0.000 01). The results of two studies showed that, the correlation coefficients between adenoviral infection and encephalitis were OR1=2.22 (95%CI 0.32 to 14.79, P > 0.05), and OR2=1.12 (95%CI 0.14 to 9.10, P > 0.05), respectively, both with no significant difference. In addition, the subgenus B adenoviruses, including type 3 and type 7 were more associated with encephalitis, followed by type 1 and type 2 in subgenus C and type 8 in subgenus D. ConclusionCurrent evidence shows that no correlation exists between adenoviral infection and encephalitis in children. However, the above conclusion needs to be verified by conducting more rationally-designed studies so as to clarify the correlation.
