Objective To study the effects of ulinastatin on proinflammatory cytokine and oxygen free radicals during acute lung injury in rabbits. Methods Eighteen health New Zealand rabbits were randomly divided into 2 groups: oleic acid group(n=9) and ulinastatin group(n=9). The rabbits of oleic acid group were intravenously injected analytical pure oleic acid(0.12ml/kg) to set up a model of acute lung injury. The rabbits of ulinastatin group were intravenously injected ulinastatin 50000u/kg before injecting oleic acid and received intravenous infusion of ulinastatin 5000u?kg -1 ?h -1 after injecting oleic acid. Before injecting oleic acid and 1h, 2h, 3h and 4h after injecting oleic acid,venous blood samples were taken to determine the concentration of plasma IL-8, MDA and active oxygen,and arterial blood samples were also taken for gas analysis. Results The concentration of IL-8, MDA and active oxygen and PaCO 2 gradually increased,and PaO 2 gradually decreased after injecting oleic acid in the both groups of rabbits. The changes of the above indices in the oleic acid group were larger than those in the ulinastatin group, and the difference between the two groups was significant. Conclusion Ulinastatin inhibited the release of proinflammatory cytokine and reduced the production of oxygen free radicals during acute lung injury.

Objective To identify the early warning signs of severe preeclampsia (SPE). Methods A case-control (1: 2) observational study was conducted. Forty-seven pregnant women with SPE, who attended the prenatal clinics of Peking University Third Hospital regularly from Jan. 2002 to Dec. 2007, were selected as the study group, including 12 early onset and 35 late onset ones. The control group consisted of 94 healthy singleton pregnant women at the same period. Clinical data were collected and analyzed. Results (1) The basal body mass index (BMI) showed no difference between the study and control group [(23.27±4.31)kg/m2 vs (21.52±3.09)kg/m2, P>0.05]. (2) The net increase of BMI in the study group before the onset of SPE was higher than that in the control [(5.60±2.17)kg/m2 vs (4.85±1.52)kg/m2, P<0.05] and the increase of BMI per week was also higher [(0.74±0.41)kg/(m2*w)-1 vs (0.23±0.18)kg/(m2*w)-1, P<0.01]. The sensitivity and specificity of BMI increase per week in predicting SPE was 84% and 81% at a cut-off value of 0.39 kg/(m2*w)-1, respectively, and 79% and 91% at 0.41 kg/(m2*w)-1 correspondingly. (3) During the third trimester and before the onset of SPE, the weight gain per week in the study group was higher than that of the control [(0.93±0.70)kg vs (0.63±0.20)kg, P<0.01]. Significant difference was also found in the net weight gain between the two groups (P<0.01), but not in the percentage of women with excessive weight gain (>0.50 kg/w) [60%(25/42) in the study group vs 63%(53/84) in the control group, P>0.05]. (4) Higher percentage of women experienced pre-hypertension in the study group than in the controls [17%(8/47) vs 5%(5/94), P<0.01]. (5) In the study group, 53%(25/47) of the women had edema before SPE onset, but the figure dropped to 18% (17/94) in the controls(P<0.01). (6) Eight women in the study group and one in the control group suffered from hypoproteinemia before SPE onset with the average level of plasma albumin of (32.6±1.6)g/L and(38.4±2.1)g/L(P<0.01), respectively. (7) Proteinuria was reported in 10 cases (21%)in the study group and 4(4%) in the controls (P<0.01). (8) Logistic regression analysis showed that the risk factors for SPE included edema (OR=6.16,95%CI:2.29-16.57),pre-hypertension (OR=6.21,95%CI:1.56-24.77),proteinuria (OR=9.68,95%CI:1.86-50.30), and weight gain >0.85 kg/w during the third trimester (OR=11.60,95%CI:3.54-37.97). Conclusions Edema, excessive weight gain,pre-hypertension and hypoproteinemia are early warning signs of SPE. Pregnant women with the above signs required close monitoring during prenatal care.

Objective To investigate whether inhibiting the expression of typeⅠ collagen gene is one of the mechanisms of action of electroacupuncture in improving knee osteoarthritis.Methods Forty male adult SD rats were randomized into normal, model, medication and electroacupuncture group, 10 rats each. A rat model of MIA-induced knee osteoarthritis was made by injecting monomer sodium iodoacetate (MIA) and driving rat movement. After model making, the medication group received an oral gavage of celecoxib dissolved in 10% DMSO and the electroacupuncture group, electroacupuncture at points Zusanli and Yanglingquan. Pain thresholds and the levels of cartilage expression of typeⅠ collagen mRNA were compared between various groups of rats before and after treatment.Results There was a statistically significant difference in pain threshold between the model, medication or electroacupuncture group of rats and the normal group after model making (P<0.01) and between the medication or electroacupuncture group of rats and the model group before sacrifice (P<0.01). There was no statistically significant difference in pain threshold between the medication and andelectroacupuncture groups of rats before sacrifice (P>0.05). There was a statistically significant difference in the expression of typeⅠ collagen mRNA between the model, medication or electroacupuncture group of rats and the normal group (P<0.01) and between the medication or electroacupuncture group of rats and the model group before sacrifice (P<0.01). There was no statistically significant difference in the expression of typeⅠ collagen mRNA between the electroacupuncture and medication groups of rats before sacrifice (P>0.05).Conclusion The mechanisms of actions of electroacupuncture and medication in treating knee osteoarthritis may be related to inhibiting the expression of typeⅠ collagen mRNA.

Objective: To investigate the protection roll of rosuvastatin on chronic heart failure (CHF) in rats with its effect on asymmetric dimethylarginine (ADMA) metabolic pathway.
Methods: A total of 36 male SD rats were randomly divided into 3 groups, n=12 in each group. Isoproterenol (ISO) group, the rats received ISO subcutaneous injection (5mg·kg·d) for 7 days to establish CHF model, and then received normal saline gavage administration for 7 days. Rosuvastatin (ROS) treatment group, the rats received ISO with ROS for 7 days, then continuously receiving ROS until 14 days. Normal control group, the rats received saline gavage administration for 7 days. The related serum index and haemodynamic parameters were examined, myocardial pathological changes were observed and the relevant protein expression was measured by Western blot analysis.
Results: Compared with Normal control group, ISO group had obviously increased troponin (cTn I), serum ADMA,-LVdP/dtmin, all P<0.01, and decreased left ventricular systolic pressure (LVSP), heart rate, arterial SP, mean arterial pressure, +LVdP/dtmax, all P<0.01. Compared with ISO group, ROS treatment group showed signiifcantly decreased BNP, cTn I, ADMA , -LVdP/dtmin, all P<0.01, and increased LVSP, heart rate, arterial SP, mean arterial pressure,+LVdP/dtmax, all P<0.01. Compared with Normal control group, ISO group had increased expression of protein arginine methyltransferases 1 (PRMT1), decreased expression of dimethyl- arginine dimethylaminohydrolase 2 (DDHA2), both P<0.01. Compared with ISO group, ROS treatment group showed decreased expression of PRMT1, P<0.01 and similar expression DDHA2, P>0.05.
Conclusion: Rosuvastatin has the protective roll on ISO induced CHF in rats, which might be related to decreased serum levels of cTn I, BNP and ADMA metabolic pathway regulation.

Objective:To study the in vitro antimicrobial activity of traditional Chinese medicine herbal pair of euphorbia humifusa Willd. and portulaca oleracea L. . Methods: The antibacterial effect in vitro of the traditional Chinese medicine herbal pair and the single herb of euphorbia humifusa Willd. and portulaca oleracea L. was studied on staphylococcus aureus, escherichia coli and pseudo-monas aeruginosa by the 2-fold dilution method and the broth micro-dilution method in a 96-well plate. The minimum inhibitory con-centration ( MIC) , minimum bactericidal concentration ( MBC) and the diameter of inhibition zone were determined. Results:The ex-perimental strains showed the different sensitivity among the traditional Chinese medicine herbal pair and the single herb. The antibac-terial and bactericidal activity of the traditional Chinese medicine herbal pair was the most obvious(P<0. 05). As the temperature in-creasing, the antibacterial activity of all water extract on different experimental strains changed. The results of MIC and MBC showed that the effects of water extract on escherichia coli were strongest, that of stapphylococcus aureus were secong, ant that of pseudomonas aeruginosa were relatively weak. Conclusion:The traditional Chinese medicine herbal pair of euphorbia humifusa Willd. and portulaca oleracea L. has antibacterial and bactericidal activity in varying degrees on the experimental strains with some differences, and the changes in the application forms of traditional Chinese medicines has great influence on the antibacterial and bactericidal ability.
