Objective To investigate the relationship of pulmonary surfactant protein D( SP-D) with chronic obstructive pulmonary disease ( COPD) by measuring SP-D level in serum and lung tissue of rats with COPD.Methods The rat COPD model was established by passive smoking as well as intratracheal instillation of lipopolysaccharide ( LPS) . Thirty male SD rats were randomly divided into a control group, a LPS group, and a COPD group( n =10 in each group) . The pathologic changes of lung tissue and airway were observed under light microscope by HE staining. Emphysema changes were evaluated by mean linear intercept ( MLI) of lung and mean alveolar number ( MAN) . The level of SP-D in serum was measured by enzymelinked immunosorbent assay ( ELISA) . The expression of SP-D in lung tissue was detected by Western-blot and immunohistochemistry.Results The MLI obviously increased, and MAN obviously decreased in the COPD group compared with the control group ( Plt;0.05) . There was no significant difference in the MLI and MAN between the LPS group and the control group ( Pgt;0.05) . The serum SP-D level was ( 49.59 ±2.81) ng/mL and ( 53.21±4.17) ng/mL in the LPS group and the COPD group, which was significantly higher than that in the control group [ ( 42.14±2.52) ng/mL] ( Plt;0.05) . The expression of SP-D in lung tissue was 0.56±0.01 and 0.63±0.01 in the LPS group and the COPD group, which was also obviously ber than that in the control group ( 0.39 ±0.01) ( Plt;0.05) .Meanwhile the SP-D levels in serumand lung tissue were higher in the COPD group than those in the LPS group ( Plt;0.05) . The levels of SP-D between serum and lung tissue were positively correlated in all three groups ( r=0.93, 0.94 and 0.93, respectively, Plt;0.01) .Conclusion Both the SP-D level in serum and in lung tissue increase significantly in COPD rats and correlate well each other, which suggests that SP-D may serve as a biomarker of COPD.

Methods Eighty patients in early stages of chronic renal failure in our department between September 2009 and June 2010 were randomly divided into the control group and the experimental group with 40 patients in each group. Quality and Conventional care were implemented on the two groups respectively. Six months later, self-rated health measurement scale (SRHMS V1.0) was used to analyze the impact of quality care on the patients. Results The results of the measurement showed that there were significant differences between the two groups in organ function, daily life function, physiologic health, negative emotion, positive emotion, cognitive ability, psychological health, role activity and social health (Plt;0.05). There were no significant differences between them in social support and social resources. Conclusion Carrying out high-quality care can significantly improve the active treatment confidence of the patients and can effectively control the development of the disease.
Objective To explore the role of chronic ethanol ingestion in pulmonary fibrosis. Methods Twenty SD rats were randomly divided into a control group (n=10) and an ethanol group ( n=10) , and fed with quantitative non-ethanol and ethanol Lieber-DeCarli liquid diet every day respectively. All rats were sacrificed after 8 weeks. The morphological changes and collagen deposition of lung tissue were observed under light microscope by HE and Masson staining. Levels of glutathione (GSH) and hydroxyproline (HYP) in lung tissues were measured by colorimetric method. The content of connective tissue growth factor (CTGF) in lung tissue was detected by ELISA. Results Compared with the control group, varied degrees of alveolar and alveolar septal infiltration of inflammatory cells can be shown in the ethanol group, and also some alveolar wall damage or collapse.Masson staining showed that the ethanol group has more significant deposition of collagen fibers in alveolar interstitumthan the control group. The content of GSH in rat lung tissue reduced, but the contents of HYP and CTGF increased in the ethanol group compared with the control group [ GSH( mg/g) :0.08±0.04 vs. 0.22±0.14, HYP(mg/g) : 0.57±0.15 vs. 0.40 ± 0.09, CTGF(ng/mL) :306.57±46.86 vs. 134.02±79.82, Plt;0.05] . Conclusions Lieber-DeCarli ethanol liquid diet can establish a rat model of chronic ethanol ingestion. Lung injury and pulmonary fibrosis in rats can be induced by chronic ethanol ingestion. Ethanol may be one of the causes of the pulmonary fibrosis.

Objective To explore the role of macrophage-stimulating protein ( MSP) and receptor tyrosine kinase RON in the airway inflammation of chronic obstructive pulmonary disease( COPD) , and investigate its possible mechanism. Methods The rat COPDmodel was established by exposing the rats to cigarette smoke daily for three months. Rat alveolar macrophages ( AMs) were isolated in vivo and cultured,and then challenged with different concentrations of MSP for 24 hours. The concentrations of MSP in broncho-alveolar lavage fluid ( BALF) and serum, and the levels of IL-1β, TNF-α, IL-8, and IL-10 in the supernatants were measured by ELISA. The expression of RONmRNA in lung tissue was assessed by reverse transcription-polymerase chain reaction. The levels of RON protein in the lung tissue and AMs cultured in vitro were observed by immunohistochemistry. The activity of superoxide dismutase ( SOD) and malondialdehyde ( MDA) content in the culture solution were measured with chromatometry method. Results Compared with the control group, the concentrations of MSP in serum and BALF of the COPD rats were significantly higher ( P lt;0. 01) . The levels of RONmRNA and RON protein in the COPD rats were also upregulated significantly ( P lt; 0. 01) . MSP evoked the AMs isolated from the normal and COPD rats to generate more content of MDA and caused a reduction in activity of SOD. In addition, MSP stimulated TNF-α, IL-8, IL-1βand IL-10 release fromAMs of the normal and COPD rats dose-dependently. The levels of TNF-α, IL-8, and IL-1βwere higher, while the level of IL-10 and the SOD activity were lower in AMs of the COPD group than those of the control group in the same dose of MSP ( P lt;0. 01) . The more significant increase in the levels of TNF-α, IL-8, IL-1β, and the more notable decrease in the activity of SOD was found in the COPD group compared with the control group. But the degree of increasing MDA and IL-10 in the AMs of the COPD group was lower than that in the control group. Linear correlation analysis showed that the MSP concentration and the RON protein level in the COPD rats were positively associated with the total cellcounts and AM counts in BALF, and were related to the indexes for pulmonary emphysema. Conclusions There is a close correlation between the MSP and receptor tyrosine kinase RON with the airway inflammation of COPD. The mechanism might be that MSP promote the macrophages release inflammatory factors and increase the production of oxygen free radicals.
Objective To determine if supervised hospital-based exercise can maintain the benefits of functional exercise ability and quality of life gained from a pulmonary rehabilitation program in COPD.Methods A prospective and randomized study was carried out. Following completion of an eight-week pulmonary rehabilitation program in hospital, 43 COPD patients were recruited and randomized into either a supervised group ( supervised, every 10 days, hospital-based exercise, 22 cases ) or a control group ( unsupervised home exercise,21 cases) and followed for 12 months. Measurements were taken at baseline and 12 months later. Exercise measurements include six-minute walk test( 6MWT) and pulmonary function test. Quality of life was measured using the Chronic Respiratory Questionnaire ( CRQ) . Results After 12 months of different exercise program,6MWT in the supervised group was significantly longer than that in the unsupervised group[ ( 532. 0 ±168. 4) m vs ( 485. 0 ±151. 6) m, P lt; 0. 05] . There was no significant difference in pulmonary function between the two groups. The quality of life of the supervised group was higher than that of the unsupervised group( 114. 6 ±20. 8 vs 105. 6 ±21. 7, P lt;0. 05) . Conclusions After the completion of pulmonary rehabilitation program, a supervised, every 10 days, hospital-based following exercise program can maintain better functional exercise capacity and quality of life compared to home exercise in COPD patients.
