Objective To determine the value of soluble triggering receptor expressed on myeloid cells 1 (sTREM-1) in patients with stable chronic obstructive pulmonary disease (sCOPD). Methods From 2015 January to 2015 August, 101 patients with stable chronic obstructive pulmonary disease and 81 healthy controls were en-rolled. All subjects underwent pulmonary function test to record FEV1%pred and FEV1%FVC and their serum sTREM-1 levels were determined. Arterial blood gas analyses and COPD assessment tests were also conducted in stable COPD patients. Results Serum sTREM-1 levels were significantly higher in stable COPD patients than healthy controls (113.2 ± 31.5 pg/mL and 83.8 ± 17.9 pg/mL respectively, P=0.000). sTREM-1 levels were posi-tively correlated with CAT score (r=0.507, P=0.000), whereas negatively correlated with FEV1%pred and PaO2 (r = 0.507, P = 0.000; r = 0.439, P = 0.000). Conclusion sTREM-1 is a promising biomarker to evaluate sCOPD in the future.

Objective To activate the microglia cells by using thrombin,and then to observe the effect of precondition of rosiglitazone (RGZ)-pretreated on the expression change of peroxisome proliferator-activated receptor-γ (PPARγ),nicotinamide adenine dinucleotide phosphate:quinone oxidoreductase (NQO1) and γ-glutamylcysteine synthetase (γ-GCS).Methods Microglia cells were obtained from the brain tissues of the newborn rats and were primary cultured in vitro.The microglia cells were isolated in 14 days.The isolated microglia cells were randomly devided into normal control group (control group),thrombin stimulation group (stimulation group) and rosiglitazone intervention group (RGZ + TH group).The PPARγ,NQO1 and γ-GCS were observed by immunocytochemistry and real-time polymerase chain reaction (RT-PCR) methods.Results The immunocytochemistry showed that the number of stained cells of PPARγ,NQO1 and γ-GCS in stimulation group and RGZ + TH group were increased remarkably as compared with the control group.A significant increase of the PPARγ,NQO1 and γ-GCS was observed in the RGZ + TH group compared to the others.The RT-PCR method demonstrated that the expressions of PPARγ mRNA(211.88 ± 58.75),NQO1 mRNA(182.67 ± 62.09) and γ-GCS mRNA (188.17 ± 57.06) in RGZ + TH group were increased significantly as compared with the stimulation group (119.19 ± 44.58,101.73±32.19,108.81 ±19.71) or the control group (0.34±0.21,0.73±0.46,0.30±0.13;F=181.50,286.63,614.43,all P ＜ 0.01).Conclusion Medium-dose rosiglitazone-pretreated might increase the expression of PPARγ,NQO1 and γ-GCS in microglia cells activated by thrombin.Rosiglitazone might activate the PPARγso that increase its downstream gene to achieve its anti-oxidative stress effects.

AIM:To observe the effect of rosiglitazone (RGZ) pretreatment on the expression of peroxisome proliferator-activated receptor γ( PPARγ) , nuclear factor E2-related factor 2 ( Nrf2 ) and heme oxygenase-1 ( HO-1 ) in the microglia cells activated by thrombin.METHODS:Microglia cells were obtained from the brain tissues of the newborn rats and were primarily cultured in vitro.After cultured for 14 d, the microglia cells were used in the experiment.The iso-lated microglia cells were randomly divided into normal control group, thrombin stimulation group ( TH group) , rosiglita-zone intervention group ( RGZ +TH group ) and retinoic acid intervention group ( RA +TH group ) .The expression of PPARγ, Nrf2 and HO-1 was observed by immunocytochemistry, real-time PCR and Western blot.RESULTS:The number of positive staining cells of PPARγ, Nrf2 and HO-1 in TH group, RGZ+TH group and RA+TH group were increased re-markably as compared with control group.The significant increases in PPARγ, Nrf2 and HO-1 were observed in RGZ+TH group compared with other groups.The mRNA expression of PPARγ, Nrf2 and HO-1 in RGZ+TH group was increased significantly as compared with TH group, control group or RA+TH group (P<0.01), Besides, the mRNA expression of Nrf2 and HO-1 in RA+TH group was decreased as compared with TH group or RGZ+TH group (P<0.01).The protein levels of PPARγ, Nrf2 and HO-1 in RGZ+TH group were significantly increased as compared with TH group, control group or RA+TH group (P<0.01).The protein expression of Nrf2 and HO-1 in RA+TH group was decreased as com-pared with TH group or RGZ+TH group (P<0.01).CONCLUSION:Rosiglitazone pretreatment might increase the ex-pression of PPARγ, Nrf2 and HO-1 in the microglia cells activated by thrombin.By inhibiting the expression of Nrf2 after RA pretreatment, the expression of the downstream gene HO-1 is also influenced.The anti-oxidative stress effects of rosigli-tazone might be achieved partly by modulating Nrf2 to control the downstream gene HO-1.

Objective To investigate the efficacy of bilevel positive airway pressure mechanical ventilation (BiPAP) in the patients of acute organophosphorus pesticides poisoning (AOPP) with respiratory failure. Methods 44 AOPP patients with respiratort failure were randomly divided into experimental group (n = 22) and control group (n = 22). The routine trentment was given to both groups, additional BiPAP assisted ventilation was given to the treatment group. Blood gas,heart rate and respiratory rate were detected before and 2 h,24 h,48 h after treatment, and the rote of intubatinn,mortality,duration and cost of hospitalization were compared between two groups. Results Heart rate,PaO2 was significantly increased and PaCO2 decreased in BiPAP ventilation (P <0. 05). The mortality,intubatien rate and cost of hospitalization were significantly decreased in BiPAP treatment group (P < 0. 05). Conclusion The BiPAP ventilation is certainly effective to acute organophosphorus pesticides poisoning with respiratory failure. It could obviously improve the clinical symptoms and arterial blood gas analysis, and could reduce the mortaiity, rate of intubotion,cost of hospitalization of patients of acute organophosphoms pesticides poisoning with respiratory failure.

Objective To observe the changes of macular choroidal thickness before and after laser treatment for diabetic retinopathy patients.Methods For patients with diabetes by fundus fluorescein angiography (FFA) examination,diagnosed as severe non-proliferative and proliferative diabetic retinopathy and in accordance with the laser photocoagulation treatment indications of 23 patients (45 eyes) included in the study.There were 10 cases of male,13 cases of female; the average age was (55.48±5.43) years old.All patients underwent macular grid laser photocoagulation and pan-retinal photocoagulation.The macular choroidal thickness before and after laser treatment was measured by enhanced depth imaging technique of optical coherence tomography during follow-up at 1,2,3 weeks and one month at specific sites of choroidal.The specific sites included subfoveal choroidal thickness (SFCT),from the foveal 1mm,3mm,6mm distance of nasal choroidal thickness (NCT) and temporal choroidal thickness (TCT).Results One week after the treatment,SFCT,NCT1 mm,NCT3 mm,TCT1 mm,TCT3 mm,TCT6 mm were obviously thickening (t=4.728,4.422,3.759,3.743,5.713,2.502; P＜0.05).Two weeks after the treatment the SFCT,NCT1 mm,NCT3 mm,TCT1 mm,TCT3 mm were decreased gradually (t =3.189,2.122,2.742,2.196,2.076 ; P＜0.05).The choroidal thickness returned to pretreatment level from 2 weeks to 4 weeks after treatment,the NCT6mm had no obvious change in the whole treatment period(P＞0.05).Conclusion The choroidal thickness was significantly thicker after laser photocoagulation treatment within 1 week,with the time prolonging the choroidal thickness gradually decreases.

Objective To compare the pharmacokinetic profile of propofol after a single intravenous dose during induction in the elderly and young patients. Methods Eighteen ASA I-II patients undergoing elective gastro-intestinal and intracranial surgery were studied. Patients with abnormal liver and/or kidney function were excluded. The patients were premedicated with intramuscular phenobarbital 100mg and scopolamine 0.3mg 1h before operation. The patients were divided into two groups according to their age; the young and middle-aged group, aged between 31-57, on average 46. 5yr (A, n=6); the elderly group, aged between 67-81 yr, on average 74.6 yr(E, n = 12) . Group E was further divided into two subgroups: E1 aged between 67-73 yr, on average 69 .3 yr (n = 6); E2 aged between 76-81 yr,on average 78. 7 yr ( n=6 ) . In group A anesthesia was induced with propofol 1 . 5rng kg-1 , midazolam 0.03-0.06mg kg-1 , fentanyl 3-5ugkg-1 and vecuronium 0. 1 mgkg-1 . In group E propofol 1.0 mgkg-1 was given but the doses of the other three drugs for induction were the same as in group A. Anesthesia was maintained with isoflurane 0.5%-2.0% supplemented with intermittent iv boluses of fentanyl, vecuronium and midazolam. ECG, BP, SpO2 , PET CO2 , CVP and urine output were continuously monitored during anesthesia. Propofol was given in bolus through the vein in the forearm slowly over 30-45 s, and blood samples were taken from internal jugular vein before propofol injection and 1 ,2,4 ,6,10,15,30,45,60,75, 90,120 ,150 ,180,240 ,300,360min after the end of propofol injection for measurement of plasma propofolconcentration by HPLC with fluorescence detection. Results The pharmacokinetics of propofol in the 18 patients were best described by a three compartment pharmacokinetic model. The dose-corrected mean plasma concentrations of propofol in group A were lower at 1,2,4,6,10 min after the end of propofol injection (P
