Objective To investigate the estimated values of sequential organ failure assessment (SOFA) and quick SOFA (qSOFA) for diagnosis and prognosis in patients with sepsis according to the new diagnostic criteria in Sepsis 3.0.Methods A retrospective study was conducted.All the clinical data were collected from patients with definite diagnosis of infection and they were admitted into the Intensive Care Unit (ICU) of Beijing Traditional Chinese Medicine Hospital Affiliated to Capital Medical University from July 2014 to June 2016.The patients' gender,age,infectious location,respiratory rate (RR),oxygenation index (PaO2/FiO2),Glasgow coma scale (GCS),total bilirubin (TBil),platelet count (PLT),serum creatinine (SCr),serum lactate level,etc.general data on admission were collected to carry out SOFA and qSOFA scorings.And then the septic patients in accord with the diagnostic criteria of Sepsis 3.0 were screened out.According to outcome after admission,the septic patients were divided into survival group and death group,and the differences in diagnosis and in estimation value of prognosis between SOFA scoring and qSOFA scoring were assessed as SOFA group and qSOFA group.Results From 545 septic patients enrolled,189 septic patients consistent with the diagnostic criteria of Sepsis 3.0 were selected.In SOFA scoring group,the morbidity of septic patients was 34.68％,while in qSOFA scoring group,it was 15.96％,the difference between the two groups being statistically significant (P ＜0.01).The mortality was significantly lower in SOFA scoring group than that in qSOFA scoring group [28.04％ (53/189)vs.42.53％ (38/87),P ＜ 0.05].The mortality of qSOFA scoring group was about 1.52 times that of SOFA scoring group.On the aspect of scoring,in patients with SOFA scoring the score of death group was significantly higher than that in survival group (8.74 ± 0.417 vs.7.10 ± 0.235,P ＜ 0.01);in the patients with qSOFA scoring,the score in death group compared with that in survival group showed uo statistical significant difference (2.32 ± 0.48 vs.2.16 ± 0.37,P ＞ 0.05).On the aspect of laboratory indexes,the levels of GCS score in death group was significantly lower than that in the survival group (8.15 ± 0.67 vs.12.48 ± 0.36),blood lactate level in death group was significantly higher than that in the survival group (mmol/L:8.55 ± 4.66 vs.2.31 ± 0.16,P ＜ 0.01);the PaO2/FiO2,TBil,PLT and SCr showed no significant differences between the two groups (all P ＞ 0.05).Conclusions The new diagnostic criteria (Sepsis 3.0) can be used for diagnosis of sepsis in ICU.Compared with qSOFA scoring,the SOFA scoring is more suitable to be used for diagnosis and predicting prognosis of septic patients in ICU;SOFA scoring,GCS scoring and serum lactate level can be applied to estimate outcome of septic patients.

Objective To explore the relationship between pulmonary arterial hypertension (PAH)associat-ed with chronic obstructive pulmonary disease (COPD) and inflammatory reaction(inflammatory cell, bs CRP, IL-8 and TNF-α). Methods According to echocardiography results, the patients (systolic pulmonary artery pressure, SPAP>30 mm Hg) were divided into PAH group(n=36), single COPD group(n=32). All of the patients and 30 healthy subjects (control group) were recruited into the study. Lung function, arterial blood gases, cell differentials in induced sputum, and the levels of serum high sensitivity CRP(hs-CRP), IL-8, TNF-α were determined. Results The incidence of PAH associated with COPD were 53% (36/68),including 27% (3/11) of mild PAH,38% (5/13) of moderate PAH and 64% (28/44) of severe PAH and there were significantly differences in the severity of the spirometric abnormality (χ26.020, P<0.05). The mean PASP and right ventricle wall thickness (RVWT) in PAH group were significantly greater in the patients compared to single COPD[PASP: (52±15)mmHg in PAH group and (23±12) mm Hg in single COPD group, t=3.32,P<0.01 ; PVWT: (5.03±1.04 )mm in PAH group and (3.78±0.57)nun in single COPD group, t=2.36, P<0.05]. The levels of total cell count and neutrophils in induced sputum,hs-CRP,IL-8 and TNF-α in PAH group were higher than those in single COPD group and healthy subjects[toal cell count: (2.84±0.56)×109/L in PAH group and (1.73±0.42)×109/L in single COPD group and (0.68±0.21)×109/L in control group; neutrophils: (2.78±0.52)×109/L in PAH group and (2.57± 0.26)×109/L in single COPD group and (0.63±0.21 )×109/L in control group; hs CRP: (32±12) mg/L in PAH group and (23±11)mg/L in single COPD group and (11±4)mg/L in control group; IL-8: (113±34) ng/L in PAH group and (69±24) ng/L in single COPD group and (38±11) ng/L in control group; TNF-α: (206±63)ng/L in PAH group and (153±54)ng/L in single COPD group and (75±26)ng/L in control group (P<0.05)]. PASP in PAH group was negatively correlated with FEV<,1>% (r=-0.48,P<0.01) and was positively correlated with the levels of serium IL-8 and TNF-α, neutrophils in induced sputum respectively(r=0.43,0.56,0. 47,P<0.01). Conclusion Inflammation reaction is responsible for PAH associated with COPD.

Objective To investigate the effect of breviscapine on lung injury in children undergoing open heart surgery with cardiopulmonary bypass(CPB).Methods Forty-five ASA Ⅱ or Ⅲ children aged 3-65 months weighing 5-21 kg undergoing open heart surgery with CPB were randomly assigned to 3 groups ( n =15 each):control group (group C),low dose breviscapine group (group B1 ) and high dose breviscapine group (group B2).Normal saline 15 ml(group C),breviscapine 0.5 mg/kg (group B1 )or 1.0 mg/kg(group B2 ) were injected iv over 30min after anesthesia induction.Blood samples were taken before operation ( T0 ),at 30 min and 1 h of aortic unclamping (T1,T2 ),at 3 h and 6 h after operation (T3,T4 ) for determination of plasma procalcitonin (PCT)and neutrophil elastase(NE) concentrations.PaO2 and PaCO2 were recorded at T0,T3,T4 for caculation of oxygenation index (OI) and alveolo-arterial oxygen partial pressure difference (PA-a O2 ).Results There were no significant differences in OI and PA-a O2 among the 3 groups( P ＞ 0.05).Plasma concentration of PCT was higher at T1～4in 3 groups,and plasma concentration of NE was higher at T1 in group C than that at T0 ( P ＜ 0.01 ).Plasma concentrations of PCT and NE were lower in groups B1 and B2 than in group C ( P ＜ 0.01).There were no significant differences in plasma concentrations of PCT and NE between groups B1 and B2 ( P ＞ 0.05).Conclusion Breviscapine(0.5,1 mg/kg) can inhibite systemic inflammatory response and attenuate lung injury in children undergoing open heart surgery with CPB.

Objective To establish a method of gold nanoprobe-based solution hybridization (GNBSH) to detect nucleic acid sequence-based amplification (NASBA) products for the rapid diagnosis of invasive aspergillosis (IA).Methods The Aspergillus specific 18S rRNA was amplified by NASBA and then the amplified products were hybridized with the gold nanoprobes which were modified with thiol compounds at the 5'end.Serum samples from 106 patients,including 14 with a definite IA,32 with suspected IA and 60 without IA,were detected by the established method,and the obtained results were compared with that of galactomannan (GM) test to evaluate its accuracy.Results The gold nanoprobes only hybridized with Aspergillus NASBA products but not other non-Aspergillus strains.The sensitivity,specificity and the area under the ROC curve (AUCROC) of the established GNBSH method for detecting 106 clinical samples were 82.61％ (38/46),81.67％ (49/60) and 0.890,respectively.The sensitivity,specificity and AUCROC of GM test were 56.52％ (26/46),83.33％ (50/60) and 0.723,respectively.Conclusion The established GNBSH method to detect Aspergillus NASBA products has high sensitivity and specificity and simple operation,which may be used to detect the infection of Aspergillus by clinical laboratories.

Objective To evaluate the effects of lipoxin A4 (LXA4) administered at different time points on the expression of connexin43 (Cx43) during myocardial ischemia-reperfusion (I/R) in rats.Methods Seventytwo healthy male Sprague-Dawley rats,weighing 200-250 g,wcre equally and randomly divided into 6 groups:groups sham operation Ⅰ (group S1) and Ⅱ (group S2),groups myocardial I/R Ⅰ (group Ⅰ/R1) and Ⅱ (group I/R2),and groups LXA4 administered before chest opening (group LX1) and at 30 min of reperfusion (group LX2).Myocardial I/R was produced by 30 min occlusion of left anterior descending branch (LAD) of coronary artery followed by 120 min reperfusion.LXA4 100μg/kg was injected via femoral veins before chest opening and at 30 min of reperfusion in groups LX1 and group LX2,respectively.While normal saline 2 ml/kg was injected via the femoral vein at the corresponding time points in the other four groups.In groups S1 and S2,LAD was only threaded,but not ligated.Blood samples were taken from the femoral vein before chest opening and at 120 min of reperfusion for measurement of serum IL-8,TNF-α and cardiac troponin Ⅰ (cTnI) concentrations.The rats were then sacrificed after blood samples were taken at 120 min of reperfusion and hearts were removed for determination of Cx43 protein (by immunohistochemical SP method) and Cx43 mRNA expression (by real-time quantitative PCR),SOD activity and MDA content in myocardial tissues.The development of arrhythmia was observed from occlusion of LAD to 120 min of reperfusion.Duration of ventricular tachycardia (VTd) and ventricular fibrillation (VFd) was recorded.Scores of ventricular arrhythmias were calculated.Results The expression of Cx43 protein and mRNA was significantly down-regulated,and scores of ventricular arrhythmias,VTd,serum IL-8,TNF-α and cTnI concentrations,SOD activity and MDA content were increased in groups I/R1 and LX1 as compared with group S1,and in groups I/R2 and LX2 as compared with group S2 (P ＜ 0.05).The expression of Cx43 protein and mRNA was significantly up-regulated,SOD activity was increased,and scores of ventricular arrhythmias,VTd,VFd,serum IL-8,TNF-α and cTnI concentrations,and MDA content were decreased in group LX1 as compared with group I/R1,and in group LX2 as compared with group I/R2(P ＜ 0.05).The expression of Cx43 protein and mRNA was significantly lower,scores of ventricular arrhythmias,VTd and SOD activity were higher,and the serum IL-8,TNF-α and cTnI concentrations and MDA content were lower in group LX2 than in group LX1 (P ＜ 0.05).Conclusion LXA4 administered before myocardial ischemia and at 30 min of reperfusion can up-regulate the expression of Cx43 and reverse remodeling of Cx43,thus reducing myocardial I/R-induced arrhythmia in rats,and LXA4 administered before ischemia can provide better efficacy.

Objective To explore a new way assisted by digital technology to establish a quantitative index to assess the matching performance of anatomically contoured plate. Methods We collected the thin-slice CT data of 20 adults with normal tibias who had received 32-slice spiral CT scanning from April 2015 to June 2016. They were 10 males and 10 females, aged from 28 to 52 years (average, 36.2 years). 3D reconstruction of the tibias was performed with Mimics 18.0. Two brands of 8-hole anatomically contoured plate for distal tibia (Kongli versus GE) were digitized. The curve of the plate facing the bone surface was extracted. The operational process of putting the plate curve on the medial surface of the distal tibia was simulated in Rhino 5.0. The volume of the gap between plate curve and bone surface was measured. The mean distance of the gap between plate cure and bone surface was figured out after the volume divided by the plate area. The inverse value of the mean distance of the gap was used as the index for matching performance. The wall thickness analyzing tool in 3-matic Research was used to mark the various thicknesses of the gap with different colors. The matching performances of the 2 brands of plate were assessed and compared according to the matching performance index and nephogram. Results Of the Kongli 8-hole distal tibial plate, the gap volume was 3,834 mm3± 701 mm3, the mean thickness 1.8 mm ± 0.3 mm, and the matching index 0.56 ± 0.10. Of the GE 8-hole tibial plate, the gap volume was 7,690 mm3± 1,503 mm3, the mean thickness 3.0 mm ± 0.6 mm, and the matching index 0.34 ± 0.06. The significant difference in matching performance between the 2 kinds of plate favored the Kongli plate (t=10.402, P <0.01). There were no significant differences in matching per-formance between different genders among the plates of the same brand (P> 0.05). The nephogram showed a large fixed red area at the proximal part in the GE 8-hole tibial plate. Conclusions As this index for matching performance is simple and intuitive, it can be used to assess and compare the matching performances between different kinds of plates. It can be also used before operation to assess the matching performance of a specific plate for a specific patient to avoid mismatch because of individual differences.
