The clinical diagnosis includes the presence of an upper genital tract infection and inflammation in the patient. PID comprises a spectrum of inflammatory disorders of any combination of endometritis, salpingitis, tubo-ovarian abscess (TOA), and pelvic peritonitis. PID is difficult to diagnose because of a wide variation in the symptoms and signs. Early diagnosis with the help of successful laboratory testing is one way to avoid invasive laparoscopy or laparotomy and is beneficial for the patients, therefore our laboratory made efforts in the investigation of the mechanism of pelvic inflammatory disease and the relationship of different plasma protein concentrations and PID. Plasminogen activator/ plasma system is the inhibitor of the production of fibrin and acts on the degradation of fibrin. As well, is associated with the degradation of tissue basement, fibrination, tissue regeneration, and vascular angiogenesis, as well as the activation of macrophage and metastasis of tumor. However, it has been found that plasminogen activator is associated with the development of inflammation. In this study, we will investigate the association between plasminogen activator and pelvic inflammatory disease. Up to now, our laboratory has established some of the assays, such as zymography, Western blotting, RT-PCR, and EMSA for our investigation of PID. Using casein zymography assay, we found that the plasma concentrations of u-PA of PID patients were elevated before they received treatment compared with after receiving treatment in our preliminary data. During the first year of this proposed project, we will 【1】examine the plasma concentration of u-PA, soluble u-PAR, t-PA, PAI-1, and PAI-2 of one hundred PID patients compare with those of one hundred healthy individuals using ELISA assay. Additionally, we will estimate the interaction effect between those proteins and clinical information such as risk factors of PID, infection types of bacteria, white blood counts, neutrophils, and CRP, after obtaining the permissions from subjects. 【2】examine the plasma concentration of u-PA, soluble u-PAR, t-PA, PAI-1, and PAI-2 of one hundred PID patients before and after receiving treatment using ELISA assay. Additionally, we will estimate the interaction effect between those proteins and clinical information such as risk factors of PID, infection types of bacteria, white blood counts, neutrophils, and CRP, after obtaining the permissions from subjects, and estimate the relationship between PID prognosis and those proteins. 【3】 estimate mRNA expression levels of u-PA, u-PAR, t-PA, PAI-1, and PAI-2 of PBMC obtained from peripheral blood of one hundred PID patients before and after receiving treatment using RT-PCR and real time RT-PCR, particular for the estimation of u-PAR mRNA expression. As well, we will further estimate the different expression level and ratio between soluble u-PAR and membrane u-PAR. In addition, we will estimate the interaction effect between those proteins and clinical information such as risk factors of PID, infection types of bacteria, white blood counts, neutrophils, and CRP, after obtaining the permissions from subjects. 【4】estimate activity of plasma t-PA and u-PA of one hundred PID patients before and after receiving treatment using casein zymography. In addition, we will estimate the interaction effect between those proteins and clinical information such as risk factors of PID, infection types of bacteria, white blood counts, neutrophils, and CRP, after obtaining the permissions from subjects. From year two through year three, we will 【1】estimate the contributions of gene polymorphisms of u-PA, u-PAR, t-PA, PAI-1, and PAI-2 on the development of PID using PCR-RFLP after extration of genomic DNA from one hundred PID patients and one hundred healthy individuals. Additionally, we will estimate the interaction effect between those gene polymorphisms and clinical information such as risk factors of PID, infection types of bacteria, white blood counts, neutrophils, and CRP, after obtaining the permissions from subjects, and estimate the relationship between PID prognosis and those gene polymorphisms as well as the relationship between protein expression and gene polymorphism, and these effects on PID prognosis. 【2】 estimate the relationship between gene polymorphism and plasma protein expression level of u-PA, soluble u-PAR, t-PA, PAI-1, and, PAI-2, respectively, in PID patients as well as healthy controls. 【3】establish an in vitro study to demonstrate whether different gene polymorphisms will induce different expression levels of mRNA and protein by establisnment of vector and tranfection of specifically significantly differenc gene polymorphisms into HeLa 229 epithelial cell and ECC-1 human uterine epithelial cell, and then estimate those effects using RT-PCR, real time RT-PCR, western blotting and ELISA 【4】estimate gene polymorphism effect on gene expression of inflammatory factors, such as IL-1, TNF-alpha and IL-6, and inflammatory transduction mediators, such as MAPK family ERK 1/2, p38, JNK 1/2, and phosphatidylinositol 3-kinase(PI3K)/Akt pathway in HeLa 229 epithelial cell and ECC-1 human uterine epithelial cell after tansfection of those gene polymorhisms into the both cells. During the third year of this proposed project, we will 【1】estimate mRNA and protein levels of u-PA, soluble u-PAR, t-PA, PAI-1, and PAI-2 of of HeLa 229 epithelial cell, HEC 1B cell, and ECC-1 human uterine epithelial cell using RT-PCR, real time RT-PCR, western blotting, and ELISA assay, after transfection of IL-1, TNF-α, and LPS (lipopolysaccharide) into those epithelial cells. 【2】estimate whether the altered secretion levels of u-PA, soluble u-PAR, t-PA, PAI-1, and PAI-2 of epithelial cells, which induce by IL-, TNF-α, and LPS, are mediated through signal transduction pathway, such as
