Pulmonary surfactant is a complex mixture of lipids and surfactant proteins (SP) lining the alveolar surface.In addition to the well established ability of the surfactant system to reduce alveolar surface tension and thereby prevent collapse of the alveoli on expiration,it is also involved in pulmonary host defence.Surfacant protein-A (SP-A),one of the most abundant SP,can deal with various pathogens,using a range of innate immune mechanisms,and links innate immunity with adaptive immunity that includes modulation of dendritic cell function and helper T cell polarization.Surfactant-replacement or increasing SP-A generation might be efficacious for the treatment of inflammatory and infectious diseases in the lung.

ObjectiveTo investigate the effect of different degrees of pressure of sustained inflation (SI) in patients with acute respiratory distress syndrome (ARDS) after lung recruitment as the result of different negative pressure for sputum aspiration.Methods A prospective single-blind randomized controlled trial was conducted. The factorial analysis of variance was adopted. 150 patients with ARDS admitted to the emergency intensive care unit (ICU) of Chongqing Three Gorges Central Hospital from January 2012 to December 2014 were enrolled, and they were randomly divided into S1, S2, S3 group, with 50 patients in each group, suction pressure varying from 150, 175, to 200 mmHg (1 mmHg = 0.133 kPa) was respectively used in each group. Then the patients of each group were randomly subdivided into five subgroups of P0, P1, P2, P3, P4, with 10 patients in each group, and 0, 30, 35, 40, and 45 cmH2O (1 cmH2O = 0.098 kPa) were used for control pulmonary inflation pressure, respectively. The respiratory mechanics and the hemodynamic parameters were recorded, and they were compared before and after the sputum aspiration as well as lung recruitment with sustained inflation.Results The lung recruitment volume (mL: 87.56±28.47 vs. 109.38±34.63, t = 3.573,P = 0.001) and lung static compliance [Cst ( mL/cmH2O): 27.69±13.25 vs. 35.87±17.47,t = 2.814,P = 0.004] after sputum aspiration in the 150 patients were significantly lower than those before the sputum aspiration, and peak airway pressure [PIP (cmH2O): 24.16±8.28 vs. 18.63±6.67,t = 2.957,P = 0.005], airway plateau pressure [Pplat (cmH2O): 21.28±9.14 vs. 17.47±7.26,t = 2.089,P = 0.032], and mean airway pressure [Pm (cmH2O): 13.26±4.65 vs. 10.41±3.54,t = 3.271,P = 0.001] were significantly higher than those before the treatment. There were no significant differences in the lung recruitment volume, Cst, PIP, Pplat and Pm between groups with different negative pressure for sputum aspiration (F value was 0.809, 0.986, 1.121, 0.910, 1.043, andP value was 0.452, 0.381, 0.335, 0.410, 0.361), but statistical significance was found among different groups of different lung recruitment pressures (F value was 3.581, 5.028, 3.064, 3.036, 4.050, andP value was 0.013, 0.002, 0.026, 0.027, 0.007). There was no interaction between the two factors. After pairwise comparison, under the same negative pressure for sputum aspiration, lung recruitment volume and Cst in different lung recruitment pressures subgroups (P1, P2, P3, P4) were significantly higher than those of P0 subgroup, and PIP, Pplat, and Pm were significantly lower than those of P0 subgroup. There was no significant difference among P1, P2, P3 and P4 groups. There were no significant differences in mean arterial pressure (MAP) and pulmonary arterial pressure (PAP) among different groups with negative pressures for sputum aspiration and different lung recruitment pressures (negative pressure for sputum aspiration:F = 0.586,P = 0.561,F= 1.373,P = 0.264; lung recruitment pressure:F = 1.313,P = 0.280,F= 1.621,P = 0.186), there was no interaction between the two factors (F = 0.936,P = 0.497,F = 1.391,P = 0.227). The difference of heart rate (HR) in different negative pressure for sputum aspiration groups was not significant (F = 1.144,P = 0.328), and there were significant differences in different lung recruitment pressure groups (F = 3.297,P = 0.019), there was no interaction between the two factors (F = 1.277, P = 0.280). After pairwise comparison, under the same negative pressure for sputum aspiration, HR in P3 and P4 subgroups was significantly higher than that in P0, P1, and P2 subgroups (allP< 0.05).Conclusion 30 cmH2O and 35 cmH2O were the suitable pressure for SI in ARDS patients, and they were not affected by different negative pressure for sputum aspiration.

The co-metabolic carbon sources,dynamics and influence factors of atrazine biotransformation by genetically engineered microor- ganism(GEM)were investigated in the paper.The results showed that glucose was superior to acetate as co-metabolic carbon sources.The concentration of carbon sources affected little on atrazine transformation but much on GEM growth.The specific transformation rate(STR)of atrazine was influenced not by cell density of GEM but by atrazine concentration.Monod model was used to simulate atrazine transformation dynamics and the parameters were v_(max)=0.168/h and Ks=30.49 mg/L.When temperature reduced,STR decreased markedly.The trans- formation was efficient in weak alkaline condition and was inhibited in acidic condition.To some extent,salinity did not affect transformation activity of GEM.Co~(2+),Fe~(2+),Fe~(3+),and Zn~(2+) improved atrazine transformation,but Mn~(2+),Ni~(2+) and Cu~(2+) inhibited atrazine transforma- tion.The results also showed that there existed a direct correlation between adsorption and transformation of atrazine by GEM.

Objective: To explore the relationship between plasma level of N terminal pro brain natriuretic peptide (NT-proBNP) and severity of coronary artery lesion in patients with coronary heart disease (CHD). Methods: A total of 206 patients suspected CHD, who admitted from Jan 2010 to Jun 2012 in our department and underwent coronary angiography (CAG), were divided into single vessel coronary disease group (n=54), double-vessel coronary disease group (n=52), multi-vessel coronary disease group (n=67) and normal group (n=33), according to CAG examination; and divided into acute myocardial infarction (AMI) group (n=45), unstable angina pectoris (UAP) group (n=91), stable angina pectoris (SAP) group (n=43) and normal group (n=27) according to clinic symptom. All patients received measurement for NT-proBNP, creatine kinase-isoenzyme (CK-MB) and cardiac troponin I (cTnI). Stenotic severity of coronary artery lesion was evaluated using Gensini score method. Data of all groups were analyzed statistically. Results: Compared with SAP group and normal group, there was significant increase in plasma level of NT-proBNP [(2.28±0.22) vs. (2.18±0.69) vs. (2.94±0.24) vs. (2.74±0.15), P<0.01 or P<0.05] in AMI group and UAP group. Compared with normal group, there was significant increase in plasma level of NT-proBNP [ (2.07±0.43) vs. (2.44±0.38) vs. (2.69±0.34) vs. (2.98±0.28), P<0.05] in single, double and multi-vessel coronary disease groups. Plasma level of NT-proBNP was positively correlated with Gensini score (r=0.51, 0.67, 0.73 respectively in single, double and multi-vessel coronary disease group, P<0.05 all). Conclusion: NT-proBNP concentration can be regard as an index predicting severity of coronary artery lesion.
