Objective To investigate the clinical significance of multi-tumor biomarkers combined variation in patients with idiopathic pulmonary fibrosis(IPF).Methods Multiple serum tumor biomarkers,including AFP,CEA,CA125,CA153 and CA199 were detected in 25 patients with IPF and 23 healthy controls by chemiluminescence method,and the blood gas analysis,pulmonary function parameters and other clinical data were also collected simultaneously.Results All serum biomarkers measured in this study were significantly higher in IPF group than control,AFP([2.41±0.95]μg/L vs.[1.29±0.13]μg/L,t=4.32,P＜0.05),CEA([7.12±2.68]μg/L vs.[2.14±0.57]μg/L,t=3.69,P＜0.05),CA125([118.52±31.64]kU/L vs.[23.97±8.47]kU/L,t=4.15,P＜0.05),CA153([47.58±14.57]kU/L vs.[9.24±4.21]kU/L,t=5.87,P＜0.05),and CA199([165.78±21.13]kU/L vs.[14.51±5.74]kU/L,t=4.22,P＜0.05).The serum levels of AFP,CEA,CA125,CA153,CA199 were negatively correlated with blood oxygen pressure(r=-0.15--0.55,Ps＜0.05),vital capacity(r=-0.09--0.49,Ps＜0.05),lung diffusion capacity(r=-0.17--0.61,Ps＜0.05),while no significant correlations were found between different biomarker levels and ESR and CRP(Ps＞ 0.05).In addition,the serum level of different tumor markers increased along with the progress of pulmonary fibrosis,which showed statistical significance(Ps＜0.05).After hormone medication therapy,the serum tumor marker levels decreased significantly in IPF patients[AFP[2.41±0.95]μg/L vs.[1.67±1.22]μg/L,t=5.41,P＜0.05,CEA([7.12±2.68]μg/L vs.[3.75±1.96]μg/L,t=4.63,P＜0.05,CA125([118.52±31.64]kU/L vs.[53.22±13.56]kU/L,t=3.97,P＜0.05),CA153(47.58±14.5 vs.19.35±8.74 kU/L,t=5.15,P＜0.05),CA199(165.78±21.13 vs.58.85±17.31 kU/L,t=6.34,P＜0.05)].Conclusion Multiple serum tumor biomarkers significantly increased in patients with IPF,and had a close correlation with lung function damage.The changes of these biomarkers indicated the progress of pulmonary fibrosis,which served as the predictors of poor prognosis.

0.05), which were lower than that with manual compression. The failure rates were 8.3% and 9.2% respectively, but the vascular complications were less than 1%. Hematoma and femoral artery infection were seen in the PCI group, but happened less compared with manual compression. The removing of the arterial sheaths will not be limited by the anticoagulation and antiplatelet therapies, and it could be performed immediately after CAG and PCI, making hemostasis more easy to archeive. It could also reduce the burden of the medical staff, and be accepted by the patients. Conclusion Femoral arterial closure following PCI using regular and intensive anticoagulation and antiplatelet therapies could be safe and effective with vascular complication rates similar to or lower than with manual pressure.

Objective To investigate the technical features, postoperative complication and therapeutic regimen of immunosuppressant in pediatric and adolescent renal transplantation. Methods From February 1998 to December 2004, clinical data of 46 pediatric and adolescent patients who underwent renal transplantation were retrospectively analyzed to observe the patient and graft survival rate, growth and development of recipients and postoperative complication. Results Ten episodes of acute rejection (AR) were diagnosed in 46 cases. Four cases suffered delayed graft function (DGF), one urinary leakage and 8 drug-induced hepatic injury occurred. Eight cases suffered pulmonary infection, 3 cases suffered bone marrow depression and 2 granulocytopenia. One allograft artery stenosis and one ureteral necrosis occurred. Renal functions were returned to normal in all recipients 4 weeks after operation. The 1-year patient and graft survival rates were all 100 %, and the 3-year patient and graft survival rates were 100 % and 97.4 % respectively. Conclusions Renal transplantation is an effective treatment for pediatric and adolescent patients with end-stage renal disease. In addition to its higher AR incidence than adult, pediatric renal transplantation has especial treatment in the operation process and therapeutic regimen of immunosuppressant.

Objective To investigate the protein markers that specifically expressed in patients with acute rejection (ACR) after liver transplantation, and to explore preliminarily the mechanisms. Methods Serum samples from three patients with pathologically confirmed ACR after liver transplantation in Tianjin First Central Hospital were collected as ACR group. Three serum samples from patients with normal liver function indicators after liver transplantation were collected as No-ACR group. And six serum samples from healthy examination were mixed with equal amount as healthy control group. Isobaric Tags for Relative and Absolute Quantitation (iTRAQ) was employed to separate, screen and identify the differentially expressed proteins between three groups. KEGG and STRING software were applied to deeply analyze the data of three groups. Results A total of 88 differentially expressed proteins were found between ACR group and healthy control group. There were 39 differentially expressed proteins between No-ACR group and healthy control group. Ten differentially expressed proteins were acquired between ACR group and No-ACR group. Comparing 88 and 10 differentially expressed proteins, 9 proteins were the same. Among 88 differentially expressed proteins, 30 of them showed a direct interaction, and can be positioned in 13 signaling pathways based on KEGG and STRING software. Fourteen (46.67%) of the 30 proteins were located in the complement and coagulation cascade pathway. Among 39 differentially expressed proteins, which were detected between No-ACR group and control group, 10 proteins showed a direct interaction including 9 proteins concentrated in the complement and coagulation cascade pathway. Conclusion By proteomic analysis, nine differentially expressed proteins are obtained, which may be regarded as the candidate bio-markers for ACR early diagnosis after liver transplantation. The complement and coagulation cascades system is significantly adjusted after liver transplantation, indicating this pathway plays an important role in the occurrence of ACR.

Objectives To explore status of health prevention knowledge awareness and the formation of healthy behaviors of community residents in Guagzhou and provide evidence for health-management-related departments to put forward pertinent intervention strategies. Methods A questionnaire-based survey was conducted among 2 790 community residents in Guangzhou by multistage stratified random sampling. Results The awareness rate of residents′ basic health prevention knowledge was 78.14%, the awareness rate of key knowledge was 74.77%, the rate of health behavior formation was 48.14%. The rate of women′s behavior formation was higher than that of men′s. The awareness rate of basic knowledge among the residents aged over 50 years was lower than that that among those aged less than 50 years , but the awareness rate of key knowledge and behavior formation rate were higher. The level of knowledge awareness and the rate of behavior formation rate of urban residents were higher than those of rural residents and migrants. The knowledge awareness and behavior formationi were positively correlated with degree with statistically significant difference (P < 0.01). Conclusions The health belief and behavior of the community residents should be cultivated and strengthened , the basic prevention knowledge should be made universal for middle-aged and old people , the health education of key prevention knowledge should be strengthened for the middle-aged and young people , the public health services should be made more open and equal further promoted, and the community comprehensive intervention focusing on the health education should be strengthened.

Objective To investigate the relationship between the expression level of HOTAIR and cellular radiosensitivity in esophageal squamous cell carcinoma (ESCC). Methods Four ESCC cell lines ( K150, K450, TE-1, and Eca109 ) were used in this study. Quantitative real-time polymerase chain reaction was applied to measure the expression level of HOTAIR in the above cell lines;colony-forming assay was applied to measure the survival fraction of different cells irradiated by different doses of X-ray. The t-test or analysis of variance was applied for analysis of differences. The correlation analysis was used by Pearson methods. Results The four cell lines all showed high expression levels of HOTAIR and radioresistance. Compared with the other three cell lines, Eca109 had a lower expression level of HOTAIR, a lower survival fraction at each radiation dose point, and significantly lower D0 and Dq . The mRNA expression level of HOTAIR and radiosensitivity were K150

Objective To fractionate phosphoproteome of mouse liver by two-dimensional (2D) liquid phase chromatography fractionation. Methods Phosphoproteins were extracted from lysates of normal mice livers by phosphate metal affinity chromatography (PMAC) resin. The phosphoproteins were exchanged by start buffer and separated by chromatofocusing in the first dimension. Then the fractions between pH 8.5 and pH 4.0 were separated by non-porous silica (NPS) reverse-phase high performance liquid chromatography (RP-HPLC). Finally, the UV maps were converted into gel-like maps by ProteoVue software. Results Phosphoproteins of mouse liver were successfully extracted and fractionated by two dimensional liquid phase chromatographic fractionation after concentration and desalt. Then pI/UV map of mouse liver phosphoproteome was successfully set-up. There are 16 fractions between pH 8.5 and pH 4.0 after chromatofocusing in the first dimension and the UV maps of each fraction were converted into pI/UV gel-like maps. Conclusions Combination of technique of phosphoproteins enrichment and 2-D liquid phase chromatographic fractionation is an effective approach to research phosphoproteome and the key base for further identification and investigation of phosphoproteins.
