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.

Objective To study the three-dimensional topography of the hepatic vein(HV),the inferior vena cava(IVC)and the inferior right hepatic vein(IRHV)in the retrohepatic and pre-IVC tunnel in human beings,and to provide an anatomic reference for liver surgery.Methods One hundred and ten volunteers underwent CT scanning at 60 to 75 s after injection of contrast medium,and their HV,IVC and IRHV were reconstructed into MPR and 3D-MIP images.The hepatic veins were grouped according to the way by which the hepatic vein enters IVC.The angle between the right hepatic vein and the middle hepatic vein or the trunk of hepatic vein was measured,and the width from right hepatic vein to middle hepatic vein or to the trunk of hepatic vein on IVC was recorded.The frequency of IRHV was observed,and the length of the tunnel was measured.Results Among the 110 volunteers,there were 6 cases(5.45%)with three hepatic veins respectively entering IVC,98 cases(89.10%)with right hepatic vein and a common trunk of the middle hepatic vein and the left hepatic vein entering IVC,and 6 cases(5.45%)with left hepatic vein and a common trunk of the right hepatic vein and the middle hepatic vein entering IVC.The mean value of the angles between the right hepatic vein and the middle hepatic vein or the trunk of hepatic vein was(55? 18)?.The width from the fight hepatic vein to the middle hepatic vein or to the trunk of hepatic vein was (21?7)mm.The IRHV was observed in 30 cases(27.27%).The mean value of the tunnel length was (53?11)mm.Conclusion The parameters of the retrohepatic and pre-IVC tunnel in human beings can be measured accurately by the imaging of MPR,which can provide an anatomic reference for the liver surgery.

Fluorescence differential display (FDD) technique was used to identify genes that are specifically or preferentially expressed in different developmental stages of cotton fiber cells. One hundred and nine differentially displayed cDNA fragments were isolated using 9, 21 and 27 DPA (days postanthesis) fibers as experimental materials. By a combination of two rounds of reverse Northern hybridization and Northern blot analyses, a number of such cDNA fragments were proved to represent fiber-specific/preferential genes. Sequencing determination and database searching indicated that most of these genes are novel. This work is an important step towards cloning the full-length cDNAs and characterizing the cellular functions of aforementioned genes in fiber development.

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.

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 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.
