BACKGROUND: Lung fibroblasts are believed to play an important role in lung tissue repair and regenerative process. The differentiation potential of lung fibroblasts is not known very well.OBJECTIVE: To investigate the multi-differentiation capacity of human lung fibroblasts.DESIGN: An observational comparative experiment.SETTING: Department of Respiratory Medicine, Beijing Shijitan Hospital and Central Laboratory of the First Hospital of Tsinghua University.MATERIALS: This study was performed at the Central Laboratory of the First Hospital of Tsinghua University from March 2006 to October 2006. Human adult lung fibroblasts were isolated as primary cultures from resected lung of patients with lung cancer.The study was approved by hospital's Medical Ethics Committee, and informed consent was signed. Dulbecco's modified Eagle's medium (DMEM), fetal calf serum (FCS), trypsin- ethylenediamine tetraacetic acid (EDTA), naphthol AS-MX phosphate and Fast Red TR were purchased from Sigma, USA. Mouse anti-human osteopondn antibody was from R&D Systems China Co., Ltd,Polyvinyl difluoride (PVDF) membranes were from Bio-Rad Laboratories Inc, Hercules, CA.METHODS: Human adult lung fibroblasts were isolated as primary cultures. Human lung fibroblasts were cultured in an osteogenic medium (containing 109-10-5 mol/L dexamethasone, 50 mg/L vitamin C and 10 mmol/L β-glycerophospate) and adipogenic medium (containing 15% horseurm, 10-8 mol/L dexamethasone and 10 mg/L insulin), or control medium (10% FCS).Ostcoblasts were detected by alkaline phosphatese (ALP) and calcium salt staining. The expression of osteopontin was measured by Western blotting. Oil Red-O staining was used for identification of mature adipocytes.MAIN OUTCOME MEASURES: The differentiation of lung fibroblasts induced by osteogenie medium; The differentiation of lung fibroblasts induced by adipogenic medium.RESULTS: With the induction of ostcogenic medium for 2 weeks, the differentiation of lung fibroblasts was induced by osteogenic and adipogenic medium, respectively. The expression of ALP and osteopontin was increased and the deposition of calcium salt was detected. After lung fibroblasts were cultured in adipogenic medium for 14 days, part of the cells gradually experienced morphological change from original spindle into oval shape. Oil Red -O staining indicated lipid drops accumulation within cytoplasm.CONCLUSION: Under certain condition, human long fibroblasts could differentiate into osteoblasts or adipocytes that were characterized by bone marrow mesenchymal stem cells.

AIM: To study the regulatory effect of curcumin on expression of heme oxygenase-1 (HO-1) in the lung of rat treated with LPS. METHODS: Eighteen rats were divided into three groups injected with different agents via lingua vein: control group (animals received equivalent saline) , LPS group (animals received a bolus dose of LPS 5 mg?0.5 mL-1?kg-1) and LPS+ curcumin group (animals received AP- 1 inhibitor curcumin 20 mg?0.5 mL-1?kg-120 min before the injection of LPS 5 mg ?0.5 mL-1?kg-1) . The expression of HO-1 mRNA and protein in the lung were examined 7 h after LPS administration by reverse transcribed polymerase chain reaction (RT- PCR) and Western blotting, respectively. Carboxyhemoglobin (HbCO) formation within pulmonary tissue was measured to represent CO content. RESULTS: The results showed that HO- 1 mRNA and protein expression as well as CO content in the lung of rats in LPS group were significantly higher than those in control group (P

OBJECTIVE:To study the pharmacokinetics effects of naloxone combination on Shenmai injection in rats in vivo. METHODS:12 rats were randomly divided into monotherapy group (Shenmai injection 9.00 ml/kg,iv) and combination group (Shenmai injection 9.00 ml/kg+naloxone 1.80 ml/kg,iv). The blood samples were collected before administration and 0.083,0.25, 0.5,0.75,1,1.5,2,3,6,12,24,48,96 and 144 h after administration. HPLC was adopted to determine the plasma concentra-tions of ginsenosides Rg1,Re and Rb1,and DAS 2.0 software was used to calculate the pharmacokinetic parameters. RESULTS:Compared with monotherapy group,the plasma concentration of ginsenosides Rg1 in combination group was increased,CL was de-creased,t1/2 and MRT were prolonged,and AUC0-144 h was increased;the plasma concentration of ginsenosides Re was increased,Ke was decreased,t1/2 was prolonged,MRT was shortened,and AUC0-144 h was increased;the plasma concentration of ginsenosides Rb1 was decreased,Ke was increased,t1/2 and MRT were shortened,and AUC0-144 h was decreased,with significant differences(P<0.01 or P<0.05). CONCLUSIONS:Shenmai injection combined with naloxone can slow down the removing of ginsenosides Rg1 and Re in vivo,and obviously the plasma concentration of Shenmai injection is higher than monotherapy group;speed up the removing of ginsenosides Rb1,and the plasma concentration of Shenmai injection is lower than monotherapy group obviously.
