Objective: To optimize the sample pretreatment and establish an ultra-high-performance liquid chromatography coupled with hybrid quadrupole-orbitrap high-resolution mass spectrometry (UPLC-Q-Orbitrap-MS) assay based on the parallel reaction monitoring (PRM) mode for determination of antibiotic residues in chicken meat. Methods: Blank matrix-spiked chicken meat samples were extracted with 95% acetonitrile aqueous solution containing Na2EDTA and formic acid. The extraction solutions were cleaned up using different combinations of C18, PSA and GCB fillers, and the combinations with a higher antibiotic recovery rate was screened. The residues of 32 antibiotics were determined using UPLC-Q-Orbitrap-MS based on the PRM mode. Results: If the extraction solution was cleaned up using the C18 filler, the largest number of antibiotics with a spiked recovery rate of >80% was seen, with matrix effects of 82.2% to 112.6%. The detection limits of 32 antibiotics were 0.8 to 5.8 μg/kg, with linear correlation coefficients of >0.99, spiked recovery rates of 71.3% to 111.5% and relative standard deviations of 3.2% to 14.2%. Conclusion The UPLC-Q-Orbitrap-MS assay is suitable for determination and quantitative analysis of multiple antibiotics in chicken meat. Key words： high-resolution mass spectrometry orbitrap antibiotic residue parallel reaction monitoring

Objective To study the assessment value of serum protein C activity ( PC∶A) test in the patient′s condition and prognosis in bronchial asthma.Methods 202 bronchial asthma patients were selected from the Tianjin medical university general hospital from 2010 to 2012 for this retrospective cohort study, 77 males and 125 females with a mean age of 41.2 ±11.4 years.the level of PC∶A were analysed by IL ACL TOP 700 coagulation analyzer.Receiver operating characteristic curve ( ROC) was used to analyze the diagnosis performance of PC∶A, χ2 test was used to analyze the relevance between PC∶A and clinical pathological factors , Cox regression analysis model was used to evaluate the effect on prognosis , Kaplan-Meier curve to implement survival analysis.Results The elevels of PC∶A were:control group ( 102.2 ± 13.6)%, intermittent attack group (104.8 ±11.9)%, mild persistent group (136.3 ±15.8)%, moderate persistent group ( 129.0 ±13.5 )% and severe persistent ( 126.8 ±14.7 )% respectively , and there was significantly difference among the all groups ( F =7.15, P <0.01 ).Compared the control group and intermittent attack group with other groups , the PC∶A level was higher in mild persistent group ( q=16.83, q=15.54, P<0.05), moderate persistent group (q=19.94,q=12.15, P<0.05), and severe persistent group(q=11.37,q=10.66, P<0.05).The PC∶A level was lower in moderate and severe persistent group than mild persistent group ( q =3.82, q =4.30, P <0.05 ).After undergoing regular treatment for six months, the PC∶A level was higher in partly controlled group and uncontrolled group than complete controlled group (q=12.45, q=9.91,P<0.05).The optimum cut-off point of PC∶A (after undergoing regular treatment for six months ) for asthma condition with uncontrolled was 118.0%, the area under ROC curve was 0.892 ( 95% confidence interval:0.851-0.936 ).The χ2 test results showed that there was the relevance between the serum PC∶A level and the eosinocyte , total serum IgE , complicated allergic rhinitis and lung function ( FEV1%) ( P<0.01 ).The Cox analysis and survival analysis showed that the serum PC∶A level ( after undergoing regular treatment for six months ) was the independent assessment parameter for asthma acute attack in 7th-12th month, the cumulative probability of acute attack was increased obviously in the patients who with PC∶A level over the cut-off value.Conclusions The serum PC∶A level was increased obviously in asthma patients , and was related to patient′s condition, level of asthma control and severe attacks risk , which could be used as an effective indicator for assessment of disease progression and asthma control in asthma patients.

Objective To investigate the effects of continuous vennvenous haemodiafihration(CVVHDF)on major organ fimction and plasma cytokine levels in MODS dogs.Methods Fifteen Beagle dogs were subjected to hemorrhagic shock plus resuscitation and endotoxemia to establish MODS model,then dogs were randomly divided into 2 groups:CVVHDF group(n=8)and MODS group without CVVHDF (n=7).CVVHDF was performed for 12 hours after endotoxin injection in CVVHDF group dogs.Serum ALT,AST,Scr,BUN and blood gas were routinely measured,and plasma TNF-α,IL-6 and IL-10 coneentrations were measured by ELISA at different time points. Results Plasma levels of IL-6 and IL-10 were significantly decreased in the CVVHDF group at 3 h,6 h,9 h and 12 h after endotoxin injection as compared with MODS group (P＜0.01).TNF-α levels were similar in both groups(P＞0.05).IL-6 and TNF-α were detected in the ultrafihrate.The sieving coefficients (SC) for IL-6 and TNF-α were 0.27±0.13 and 0.1±0.1 respectively.IL-10 could not be detected in the ultrafiltrate.In CVVHDF group,function of major organs was improved.The beneficial effect of CVVHDF on the hypotension of MODS dogs was particularly striking at 6 h,9 h,and 12 h alter endotoxin injection(P＜0.01).Mean PaO2 in CVVHDF groups at 3 h,6 h,9 h,and 12 h after endotoxin injection was significantly higher than that in MODS group(P＜0.01). Conclusion CVVHDF effectively removes IL-6 and IL-10from the cireulation,attennates endotoxin-induced hypotension and improves arterial oxygenation in MODS dogs.
