In order to enhance their core competitiveness,hospitals will deal with medical service suppliers,patients,counterpart hospitals and other stakeholders constantly.Such multiple value activities constitute a patient-oriented and hospital-centered value group.Hospitals have to constantly meet the demand of patients in the provision of medical services,and patients will be satisfied through their own participation in medical activities,thus realize the increase of their value.The pattern of mutual value creation between hospitals and patients forms the new hospital-patient relationship.It is an important condition for the hospitals to gain competitive advantages in the medical service provision through the two models of value maximization and organization minimization,and is also profitable for the formation of a harmonious relationship between doctors and patients.

Objective To determine whether urinary neutrophil gelatinase-associated lipecalin (uNGAL) and urinary intedeukin-18 (uIL-18) are early markers of acute kidney injury (AKI) in critically ill patients. Methods Ninety-two critically ill patients were studied for one week after their enrollment into our hospital. During the study, 46 patients who met the RIFLE criteria were selected as AKI group and the remaining 46 patients without AKI taken as a control group. The two groups were matched for age, gender and illness severity. Urine samples were collected daily for one week. The receiver operating characteristic curve was used to evaluate the early diagnostic value of uNGAL, uIL-18 and serum creatininc (SCr). Results As compared with the levels obtained 3 days before the diagnosis of AKI, the uNGAL levels in the AKI group increased significantly (P <0. 05), while uIL-18 and SCr levels did not change 2 days prior to the diagnosis of A KI (all P > 0. 05). uNGAL and uIL-18 levels increased significantly (all P < 0. 05), while SCr levels did not change 1 day prior to the diagnosis of AKI in the AKI group (P > 0. 05). The levels of uNGAL, uIL-18 and SCr did not change significantly in the control group during the study period (all P > 0. 05). Three days before the diagnosis of AKI, concentrations of uNGAL, uIL-18 and SCr were not the predictive of AKI. Two days before the diagnosis of AKI, the area under the curve (AUC) of uNGAL was 0. 840 (95% CI 0. 672-1. 009, P < 0. 05), which indicated that uNGAL was the predictive of AKI while uIL-18 and SCr were not. One day before the diagnosis of AKI, the AUC of uNGAL and ulL-18 were 0. 830 (95 % CI 0. 711-0. 950, P < 0. 05) and 0. 818 (95 % CI 0. 697-0. 938, P < 0. 05), indicating that uNGAL and uIL-18 were the predictive of AKI while SCr was not. Conclusion uNGAL and uIL-18 may be the early predictive markers of AKI in critically ill patients.

Objective To evaluate the effects of sedation with propofol or dexmedetomidine on volume responsiveness in critically ill patients with acute circulatory failure. Methods Ninety?one critically ill patients with acute circulatory failure, aged 20-90 yr, weighing 40-80 kg, requiring sedation with propofol or dexmedetomidine, of Acute Physiology and Chronic Health Evaluation Ⅱ scores 12-47, of Sequential Organ Failure Assessment scores 1-18, and of NYHA Ⅰ or Ⅱ, were included. The patients were randomly divided into 2 groups using a random number table: propofol group ( n = 45 ) and dexmedetomidine group ( n=46) . Before and after propofol or dexmedetomidine sedation, when Richmond Agitation Sedation Scale score reached -2 or -1 ( BIS value 60-75) ( after sedation) , passive leg?raising (PLR) test was performed to evaluate volume responsiveness. An increase in cardiac index (ΔCI) ≥10% after PLR was considered to be a positive response, whereas ΔCI<10% after PLR was considered to be a negative response. The patients who presented with negative responses before sedation served as negative volume responsiveness subgroups ( N subgroups ) , that was PN subgroup and DN subgroup. Results The positive rates of volume responsiveness were 64% ( 14 cases) and 25% ( 5 cases) in PN and DN subgroups, respectively. The positive rates of volume responsiveness were significantly higher after sedation than before sedation in PN and DN subgroups. Compared with DN subgroup, the positive rates of volume responsiveness were significantly increased after sedation in PN subgroup. Conclusion For the critically ill patients with acute circulatory failure, both propofol and dexmedetomidine sedation can improve volume responsiveness, and propofol provides better efficacy than dexmedetomidine.

Objective To investigate the effect of stress dose glucocorticoid on patients with acute respiratory distress syndrome (ARDS) combined with critical illness-related corticosteroid insufficiency (CIRCI).Methods All early ARDS patients combined with CIRCI were screened by an adrenal corticotrophic hormone (ACTH) test and randomly divided into treatment group (hydrocortisone 100 mg intravenous,3 times/day,consecutively for 7 days,n =12 ) and control group (equivalent normal saline,n =14 ).General clinical data,changes of arterial blood gas,hemodynamics and respiratory mechanics were observed and recorded at admission and at 7 days after treatment.Ventilator-free and shock-free days,ICU stay within 28 days after admission were recorded and 28-day mortality was used as judge prognosis index.Results CIRCI rate in 45 early ARDS patients was 57.8% ( 26 patients),and the shock rate was markedly higher in ARDS patients with CIRCI than patients without CIRCI (46.2% vs 5/19 ).There were no significant differences in baseline parameters,oxygenation and illness severity between the treatment and control groups,except for markedly lower lactic level in the treatment group [ 2.7 ( 1.2,3.9 ) mmol/L vs 4.6 ( 2.5,6.3 ) mmol/L,P < O.05].After 7 days of treatment,PaO2/FiO2 markedly increased,while heart rate obviously decreased in the both groups.Compared with the control group,survival time of patients was significantly longer and shock rate of the patients was markedly lower in treatment group within 28 days (5/12 vs 10/14,P < 0.05).The 28-day mortality,which were adjusted by baseline arterial lactic,was lower in the treatment group (2.6/12 ) than in the control group (5.8/14) while with no significant difference ( P > 0.05 ).There was no significant difference in complication incidence between the two groups.Conclusion Stress dose glucocorticoid could reduce shock incidence and prolong survival time,and has a tendency of lower 28-day mortality in early ARDS patients combined with CIRCI.

Objective To assess the value of pulmonary vascular permeability index in differentiating acute lung injury (ALI) from cardiac pulmonary edema. Methods Critically ill patients with acute pulmonary edema were included from May, 2004 to September, 2008. Patients were divided into two groups, the ALI group and the cardiac pulmonary edema group (C group). Pulmonary vascular permeability index (PVPI) , intrathoracic blood volume (ITBVI) were determined by pulse indicator continuous cardiac output(PiCCO) system. Results ( 1 ) Thirty-four patients were enrolled, 22 cases in ALI group and 12 cases in C group. (2) The PVPI in patients of ALI group (2.7 ± 1.4) was higher than that of C group (1.9 ±0.6 ;P<0.05). EVLWI and ITBVI did not have the significant difference between the two groups (P >0. 05). (3) PVPI was positively correlated with EVLWI(r = 0. 762) , negatively correlated with PaO2/ FiO2(r= -0.478). (4)ARDS was diagnosed in 13 cases, including 8 pulmonary cause(ARDSp) and 5 extra-pulmonary cause ( ARDSexp). PVPI, EVLW/ITBV and EVLWI of patients with ARDSexp were obviously higher than those with ARDSp. Conclusions PVPI may be useful for differentiating the types of pulmonary edema in the critically ill.

Objective To investigate the effects of extracorporeal membrane oxygenation (ECMO) on survival of adult from acute respiratory distress syndrome (ARDS). Method We searched Pubmed, Embase, Cochrane Library, Web of Science databases to find relevant literatues on ECMO in treatment of ARDS, which are reported from January 1966 to June 2010. Meta analyses was performed. Results Three papers about randomized controlled trial (RCT) of evaluating ECMO in patients with severe ARDS were enrolled for analyses. Meta-analysis of the three randomized controlled trials revealed ECMO did not decrease the mortality of ARDS patients. However, the cumulative meta-analysis of randomized trials showed ECMO had a protective effect on patients with ARDS. The most recent observational studies suggested that ECMO significantly decreased the mortality of ARDS caused by H1 N1 viral pneumonia. Conclusions There is no evidence to prove the benefit of ECMO in patients with ARDS. However, ECMO should be considered to use in early stage of ARDS as a last rescue resort for potentially reversible severe acute respiratory failure. Further investigation of large sample of high quality RCTs is needed.
