【Abstract】 Objective To evaluate the relationship between multiple tumor biomarkers and idiopathic pulmonary fibrosis ( IPF) , and analyze the prognostic value of these biomarkers in IPF. Methods Clinical data of 43 confirmed IPF patients with no evidence of malignant disaeses, admitted in Peking Union Medical College Hospital between January 2000 and June 2010, were retrospectively analyzed. All IPF patients had detected serum alpha fetoprotein ( AFP) , cancer antigen 50 ( CA50) , cancer antigen 24-2( CA24-2) , carcinoembryonic antigen ( CEA) , carbohydrate antigen 19-9 ( CA19-9) , cancer antigen 125( CA125) , cancer antigen 15-3 ( CA15-3) , tissue polypeptide antigen ( TPA) , neuron specific enolase( NSE) , and cytokeratin-19-fragment ( Cyfra211) . Results The serum levels of CEA, CA19-9, CA125,CA15-3, and TPA were obviously higher than normal range, while the serum levels of AFP, CA50, CA24-2,NSE, and Cyfra211 were within normal range. Neither tumor biomarkers had correlation with 6-minute walk distance, FVC% pred, TLC% pred, DLCO/VA, PaO2 , PaO2 /FiO2 , P( A-a) O2 , BALF cell differentiation counting,or CD4 /CD8. The patients with increased CA19-9 level had shorter survival time than those with normal CA19-9 level ( P lt; 0. 05) . There was no significant difference in survival time between the patients with increased CEA/TPA levels and those with normal CEA/TPA levels( P gt;0. 05) , neither between the patients with glucocorticoid treatment and those with non-glucocorticoid treatment ( P gt; 0. 05) . Conclusions Multiple tumor biomarkers, especially CA19-9, increase in IPF patients. The degrees of those increases arenot associated with the severity of disease, but closely relate to prognosis, and may also indicate the progression. The increases of multiple tumor biomarkers may be a sign of poor prognosis of IPF with no evidence of malignant disaeses.
Objective To compare the difference of the changes of platelet counts after splenectomy between the patients with splenic rupture and patients with cirrhosis and portal hypertension, and to analyze the possible reasons and clinical significance. Methods The platelet count of 47 splenic rupture patients and 36 cirrhosis patients who had been carried out splenectomy from July 2008 to December 2009 in our hospital were counted, and the differences in platelet count and it’s change tendency of two groups were compared. Results In the splenic rupture group,the platelet count of all 47 patients increased abnormally after operation, the maxlmum value of platelet count among 300×109/L-600×109/L in 6 cases,600×109/L-900×109/L in 21 cases,and above 900×109/L in 20 cases. In the cirrhosis group,the maxlmum value of platelet count after operation was above 300×109/L in 26 cases,100×109/L-300×109/L in 8 cases,and below 100×109/L in 2 cases. The difference of maxlmum value of platelet count in the two groups had statistic significance(P=0.00). Compared with the cirrhosis group, the platelet count increased more significant and decreased more slow in splenic rupture group(P<0.05).The abnormal days and rising range of platelet count were higher in patient with Child A than Child B and C(P=0.006,P=0.002). Conclusions The change of platelet count after operation in splenic rupture group was obviously different from cirrhosis group because of the difference of the liver function and body situation of patients. To patients with splenic rupture or cirrhosis, appropriate treatment based on the platelet count and liver function could obtain good therapeutic effect.
