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 evaluate the efficacy and safety of early use of rapamycin in renal transplant recipients.METHODS:A total of 58 patients undergoing renal transplantation(with kidneys came from corpses)were assigned to receive cyclosporine A(CsA)plus rapamycin(RPM)and prednisone(trial group,n=28)or CsA plus mycophenolate(MMF)and prednisone(control group,n=30).The clinical efficacy at 6 months after renal transplantation,the complications and the adverse drug reactions of the two groups were observed,meanwhile,biochemical indicators including serum blood lipid level and hepatic and renal functions were monitored to analyze the effects of two immunosuppressive schemes on acute rejection of the transplanted kidneys and the survival rates of patients/kidneys.RESULTS:The transplanted kidneys in both group all survived with function.There was no significant difference between the two groups in the incidence of acute rejection(4/28(14.3%)for trial group vs.5/30(16.7%)for control group).The abnormal serum lipid level,infection of incisional wound,diarrhea and hypoleukemia were noted in 11 cases(39.3%),4 cases(14.3%),3 cases(10.7%)and 1 case(3.6%)for the trial group vs.3 cases(10.0%),2 cases(6.7%),8 cases(26.7%)and 5 cases(16.7%)for the control group.CONCLUSION:The early use of triple immunosuppressive therapy(CsA + RPM+ Pred)showed more potent immunosuppressive efficacy but fewer acute rejections as compared the control group(CsA + MMF + Pred).The main side effects of the trial group(CsA +RPM+ Pred)manifested as increased serum lipid level and infection of incisional wound,however,the incidences of diarrhea and hypoleukemia were significantly lower than in the control group.

Objective To analyze the characteristics of of organochlorine pesticides(OCPs) residues in the soil of the suburbs of Guangzhou.Methods In Baiyun,Conghua,Zengcheng,Panyu,Nansha,surface soil(0-20 cm) samples of vegetable fields,orchard and paddy soil were collected,soil profile(20-40cm,40-60cm) of Baiyun and Panyu were also collected,in Aug,2008.Gas chromatography-electron capture detector method(GC-ECD)was used to determine 17 kinds of organochlorine pesticides.Results The detection rate of 17 kinds of organochlorine pesticides was 90.59% in topsoil,the residue level was 4.19-39.89 ng/g,and the detection rate in profiles soil was 76.70 %,the residue level was 2.35-91.26 ng/g.OCPs residues were mainly HCHs and DDTs.Conclusion Detection rate of organochlorine pesticides is high in soil in the investigated soil and in the 20-40 cm profiles of Baiyun and Panyu,the level of OCPs exceeds the related standard limit,which may have adverse effects on soil environment.

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.
