In this study, the general bacterial probe and specific cellulolytic bacterial probes were used to quantify the bacteria in rumen. The total RNA were extracted and then hybridized with general bacterial probe after a dilution of concentration. The result showed that there was a high correlation between the hybridization signal and the dilution of total bacterial RNA. Based on the result above, the quantities of three cellulolytic bacteria in rumen sample were detected. The comparative RNA percentage of three cellulolytic bacteria to total bacterial RNA were similar to the previous reports. It can be concluded that the quantification of bacteria in rumen could be conducted by this approach, and which could be used in future research.

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.

OBJECTIVETo observe the effect of ERK1/2 signal pathway activated by SiO₂ in the proliferation of human embryonic lung fibroblast mediated by silicotic alveolar macrophages.
METHODThe alveolar macrophages (AM) harvested from silicotic sufferers by bronchoalveolar lavage (BAL) were interacted with SiO₂ suspension once more. HELF, pretreated with the inhibitor PD98059 (50 µmol/L) for 1 hour, were stimulated by conditional supernatant fluid of silicotic sufferers. The experimentation have been classificated four group: blank group, AM control group, SiO₂ treatment group, PD98059 intervention group. The proliferation activity and expressions of Phospho-ERK1/2 of lung fibroblast activated by AM supernatant fluids of silicotic are detected with the MTT assay, flow cytometry and Western blot method after being pretreatmented with PD98059.
RESULTThe A values of cell proliferation in SiO₂ treatment group and AM control group are 2.6 and 2.0 times that of blank group, in which the difference was statistically significant (P < 0.05). Comparing with SiO₂ treatment group, the A values of every concentrations of PD98059 intervention group decreased with a dose-response relationship, after 10, 25 and 50 µmol/L PD98059 intervention. The 25 and 50 µmol/L PD98059 intervention group were 72.1% and 48.5% of SiO₂ treatment group, which the difference is statistic (P < 0.05). The expression of phospho-ERK1/2 in SiO₂ treatment group was up, which appeared in 15 min and apparent activated in 30 min (A value is 0.4653 ± 0.0265), and then still in the higher state afterwards declined after 60 min. In addition to 15 min, the expression of phospho-ERK1/2 protein in SiO₂ treatment group at each time point are 1.25, 1.23, 1.25 times over the same period AM control group respectively, the differences were statistically significant (P < 0.05).
CONCLUSIONThe silicotic supernatant of alveolar macrophages have promote proliferation of HELF and activation of ERK1/2, which may involve in the development of silicosis pathogenesis by ERK1/2 signal pathway.

BACKGROUNDSeveral randomized controlled trials (RCTs) have compared endoscopic and symptomatic relapses in patients with erosive gastroesophageal reflux disease (GERD). We have summarized current evidence for rabeprazole 10 or 20 mg once daily for GERD maintenance treatment over 1 or 5 years.
METHODSMEDLINE, EMBASE, and the Cochrane Central Register of Controlled Trials were searched, through August 2012, for eligible RCTs of adults with erosive GERD. The efficacies of rabeprazole 10 and 20 mg/d were compared.
RESULTSThe search identified 288 citations, and five RCTs containing 1480 patients were considered eligible. Heartburn relapse rates did not differ significantly between patients treated with rabeprazole 10 and 20 mg/d for 1 year (relative risk (RR) = 1.29; 95% confidence interval (CI): 0.97-1.72), but differed in patients treated for 5 years (RR = 1.274; 95% CI: 1.005-1.615). Endoscopic relapse rates differed significantly between rabeprazole 10 and 20 mg/d for 1 year (RR = 1.92; 95% CI: 1.21-3.06), for 5 years (RR = 1.667; 95% CI: 1.073-2.589), and in combined 1- and 5-year maintenance trials (RR = 1.785; 95% CI: 1.298-2.456).
CONCLUSIONRabeprazole 20 mg/d was superior to rabeprazole 10 mg/d in preventing endoscopic relapse of erosive GERD, but that the two dosages were equivalent in symptomatic relief over 1 year.

OBJECTIVETo study the proliferation effect of the AM supernatant incubated activation of p38 mitogen activated protein kinases (p38MAPK) signal transduction pathway in human embryonic lung fibroblasts, and to participate in the development of fibrosis in silicosis.
METHODSThe silicotic alveolar macrophages were collected by bronchoalveolar lavage and incubated in vitro in the DMEM medium containing SiO₂ (50 µg/ml) and DMEM medium without SiO₂ for 18 h. Then the AM supernatant incubated for 18 h was collected. HELFs were isolated by organize paste block method, and incubated with AM supernatants. HELFs were divided into four groups: blank control groups, AM groups, SiO₂ + AM groups, SB203580 + SiO₂ + AM groups. The proliferation in the HELF was detected with MTT method and Flow cytometry.
RESULTSThe proliferation in the HELF acted with the conditioned AM supernatant fluid were more than blank control groups, AM groups and SB203580 + SiO₂ + AM groups [average optical density: (0.48 ± 0.03) vs (0.29 ± 0.01), (0.38 ± 0.02), (0.33 ± 0.03)], the values with MTT method were statistically different (P < 0.05); Proliferous index with flow cytometry in SiO₂ + AM groups (18.12 ± 0.82) was bigger than blank control groups (9.24 ± 0.48), AM groups (14.76 ± 0.43) and SB203580 + SiO₂ + AM groups (11.71 ± 0.70) and the values were statistically different(P < 0.05).
CONCLUSIONSThe AM supernatant stimulated by silicon dioxide can accelerate the proliferation in the HELF by activation of p38MAPK signal transduction pathway.

OBJECTIVETo investigate the incidence of rhabdomyolysis, the relationship between striated muscular injury and myocardiac injury, and the role of elevated serum creatine kinase (CK) played in screening these two complications following acute carbon monoxide poisoning (ACOP).
METHODS280 patients with ACOP from January 2001 to April 2003 were analyzed retrospectively. According to the clinical manifestations of striated muscular injury (swelling, pain or serious myasthenia), the patients were divided into two groups: the evident injury group and non-evident injury group.
RESULTSThe abnormality rate of electrocardiogram (ECG) and cardiac troponin I (CTnI) in the evident injury group (43 patients) were significantly higher than in the non-evident injury group (73.8% vs 43.4%, P < 0.001; 77.8% vs 20.9%, P < 0.001). There was a positive correlation between peak CK and MB isoenzyme (CK-MB) in both groups, respectively (r = 0.819, r = 0.795, P < 0.01). There was no correlation in the evident injury group (P > 0.05) and only negative correlation in the non-evident injury group (r = -0.298, P < 0.01) between peak CK and MB ratio (CK-MB/CK). Multiple regression analysis indicated that peak CK and CK-MB were only related with the striated muscular injury and were not affected by the indexes of the myocardial injury (ECG and CTnI); Both peak CK and CK-MB were positively correlated with the coma time before consultation in the non-evident injury group and the latter was also affected by CTnI. The incidence of positive muscular injury symptoms increased with the elevation of CK activity. There was no significant difference either in the ECG abnormality rate between the < 5 times elevated CK level subgroup and the > 5 times elevated CK level subgroup (P > 0.05), or in the CTnI positive rate between the normal CK level subgroup and the < 5 times elevated CK level subgroup (P > 0.05).
CONCLUSIONStriated muscular injury is not a rare complication of ACOP, and always accompanied by myocardial injury. The strikingly elevated serum level of CK in patients with ACOP might be more likely to indicate the striated muscle not myocardiac injury.
