OBJECTIVETo study the protective effect of hyperoxia solution on acute lung injury caused by phosgene poisoning by observing the changes of PaO2 and malondialdehyde (MDA) contents, superoxide dismutase (SOD) activity in serum and Glutathione (GSH/GSSG) contents in lung tissues.
METHODSThe rabbits were divided into normal control group, hyperoxia solution (H0) and balance salt (BS) groups. Group HO and Group BS inhaled phosgene and the former was given intravenously hyperoxia solution (which was replaced by balance salt solution in Group BS). The content of MDA and the activity of SOD in serum were observed at different time points, the amount of GSH and GSSG in lung tissue were also measured.
RESULTS(1) The serum MDA contents increased and PaO2, SOD activity decreased significantly in Group HO and Group BS along with time increasing as compared with control group. The contents of GSH in lung tissue decreased in two groups compared with that in control group, however the contents of GSSG ascended instead. (2) At 3 and 8 h of the experiment, PaO2 of Group HO [(9.91 +/- 0.49), (9.15 +/- 0.46) mm Hg respectively] were significantly higher than those of Group BS [(9.03 +/- 0.76), (8.11 +/- 0.57) mm Hg respectively] (P < 0.01). The contents of MDA of Group HO (3.66 +/- 0.35), (5.31 +/- 0.15) micromol/L respectively] were lower than those of Group BS [(4.32 +/- 0.26), (7.4 +/- 0.33) micromol/L respectively] (P < 0.01). SOD activity in Group HO [(237.37 +/- 29.96), (208.10 +/- 18.80) NU/ml respectively] were higher than those of Group BS [(195.02 +/- 21.44), (144.87 +/- 21.26) NU/ml respectively] (P < 0.05 or P < 0.01). The content of GSSG lung tissue in Group HO (423.67 +/- 38.21) micromol/L were lower than those of Group BS (523.85 +/- 43.14) mol/L (P < 0.01). There were no significant differences in the content of GSH in lung tissues between Group HO and group BS.
CONCLUSIONHyperoxia solution can reduce acute lung injury of rabbits following phosgene poisoning.

BACKGROUND: Many studies have suggested that angiotensin-converting enzyme inhibitors(ACEI) protect blood vessels through anti-atherosclerosis independent of lowering blood pressure, but its mechanism is still unclear.OBJECTIVE: To investigate the anti-atherosclerotic mechanism of ACEI by observing the effects of Enalapril on lipoprotein(a) and oxygen free radicals in patients with acute myocardial infarction (AMI) .DESIGN: A controlled study based on the observation of the patients with AMI.SETTING: Second Department of the South Building, General Hospital of Chinese PLAPARTICIPANTS: Thirty-five inpatients with AMI(19 males and 16 females, aged 42 -75 years old, and averaged (62 ± 9) years old and hospitalized at the Department of Cardiology of Tianjin Harbor Hospital from April 2001 to August 2002 were chosen. These patients were randomly divided into 2 groups: the therapeutic group(20 cases) and the control group(15cases). Inclusion criteria: the diagnosis of patients with AMI was confirmed by WHO criteria. Exclusion criteria: patients with renal dysfunction, shock,hypotension, a history of allergy to ACEI, and a history of severe cough induced by ACEI. All patients had not taken ACEI in the past 2 weeks and agreed to participate in this study.METHODS: On early morning of the third day after AMI, patients in the treatment group took 5 mg of Enalapril one time. If they had no first-dose reaction of hypotension, on the fourth day after AMI, the patients of the treatment group were given a dose of 5 mg twice per day for the following 2 weeks. Then, they were given the drug at a dose of 10 mg twice per day for 2 weeks. The patients in the control group were not given Enalapril. Blood samples were taken respectvely prior to the administration and 2 weeks and 4 weeks after the administration in the two groups. Serum content of lipoprotein(a), oxygen free radicals, triglyceride, total cholesterol, high density lipoprotein(HDL) cholesterol, Apo(a) were measured.MAIN OUTCOME MEASURES: We compared the level of serum of lipoprotein (a), oxygen free radicals (OFR), triglyceride, total cholesterol,HDL cholesterol, Apo(a) pre-treatment and post-treatment respectively in patients of the two groups.RESULTS: Serum levels of OFR were significantly lowered in the treatment group, which were(1 423.14±216.23), (1 076.62±287.12) and (566.57 ± 138.02) U/mL respectively 2 weeks and 4 weeks before and after the treatment(t =2. 937, 3. 571, P <0. 01), but there were no significant changes in serum concentrations of lipoprotein(a) and lipids( P > 0.05) .CONCLUSION: Enalapril improved the prognosis of patients with AMI by antioxidation, but not by lowering the serum levels of lipoprotein(a) and lipids. The study can serve as a theoretical reference that the mechanism of Enalapril might inhibit atherosclerosis in patients with AMI.

Objective To evaluate application of recombinant human luteinizing hormone (r-hLH)used in ovarian stimulation of assisted reproductive technique and impact on outcome of pregnancy. Methods From Apr. To Jul. 2009, 123 patients with low LH level ( < 1 U/L) at day 3 of menstruation and downregulation of pituitary function undergoing in vitro fertilization-embryo transfer (IVF-ET) in Reproductive Medical Center, Provincial Hospital Affiliated to Shandong University were enrolled in this study, whom were classified into 66 cases treated by r-hLH in r-hLH group and 57 cases without r-hLH treatment in non-r-hLH group. In the mean time, 145 patients with normal level of serum LH ( 1-2 U/L) not given by r-hLH treatment and undergoing IVF-ET were matched as control group. Total amount of gonadotropin, estradiol levels and LH levels on the administration of human chorionic gonadotropin ( hCG), number of oocytes retrieved, number of 2PN zygotes, rate of high quality embryos, the rates of implantation and clinical pregnancy were compared among these three groups. Results The level of serum LH on the day of hCG administration were ( 1.59 ± 0.77 ) U/L in r-hLH group, (0.54 ± 0.25 ) U/L in non-r-hLH group and (2.39 ± 1.01 ) U/L in control group, which reached tatistical difference between every two groups (P < 0.05). The rates of high quality embryo were 59.36% in r-hLH group, 57.79% in non-r-hLH group,which were significantly lower than 65.94% in control group, respectively (P < 0. 05 ). The rates of 2PN were 67.62% in r-hLH group and 68. 32% in control group, which were significantly higher than 62. 84% in non-r-hLH group, respectively ( P < 0.05 ). The rates of implantation of 29.77% in r-hLH group were significantly higher than 18.26% in non-r-hLH group ( P < 0.05 ). The total amount of gonadotropin,estradiol level on the day of hCG administration, the number of oocytes retrieved, and clinical pregnancy rate were not significantly different among those three groups ( P > 0.05 ). Conclusion The administration of recombinant human uteinizing hormone in patients who are profoundly suppressed after down-regulation with long protocol can get more quality embryos, the higher rates of 2PN and implantation.
