There are about 10560 clinical studies being (or have been) conducted in Taiwan. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
The purpose of this study is to study the change of tumor size and serum cytokine in the patients who received cryotherapy for the renal tumors.
Rheumatoid arthritis is a common chronic destructive arthritis. Major pathology change in rheumatoid arthritis is synovium hyperplasia with bone and cartilage erosion. Infiltrates in synovial tissue included type one and type two synoviocytes, B cells, T cells and fibroblasts. These cells will release many cytokines and chemokines, which will induce expression of adhesion molecules, release of variable enzyme from fibroblast and osteoclast and result in bone erosion. Recent study revealed that fibroblast-like synoviocytes (FLS) have some role in pathogenesis of rheumatoid arthritis.We believed CXCL12/CXCR4 ligand/receptor pair is important in chronicity of rheumatoid arthritis. CXCL12 polymorphism is studied in many disease. There is no related CXCL12 polymorphism study in rheumatoid arthritis. Our study intended to clarify the relationship between pathology, serology factor, CXCL12 polymorphism in rheumatoid arthritis in hope that new direction of therapy will be elucidated.
The clinically widely used X-ray computed tomography examination has a low-grade radiation effect and recently has attracted much attention concerning the possible adverse effects of radiation on human body [ref. 1-5]. The radiation is harmful to human tissues and cells mainly because it can interact with water (which makes up to 80% of cells) to generate reactive oxygen species (ROS), especially the formation of hydroxyl radicals. So far as we can reach, there is no report concerning the relation between X-ray computed tomography examination and the blood ROS level. Therefore, we wish to conduct this study to clarify if the cardiac computed tomography angiography (cardiac CTA) may induce a higher level of ROS in the peripheral blood. Study subjects will be OPD patients who are arranged for cardiac CTA examination because of suspect coronary artery disease (CAD). In total, twenty cases will be enrolled for the study. The formal consent will be delivered and explained to the patients and families after the arrangement of cardiac CTA. It then will be retrieved just before the performance of cardiac CTA. For each enrolled case, peripheral blood will be sampled three times (once before and twice after the performance of cardiac CTA). Totally 60 blood samples will be collected from 20 study subjects within 3 months (January 1 ~ March 31, 2009). ROS level in the collected blood samples will be then measured, compared, and analyzed.

So far as we can reach, there is no report concerning the relation between X-ray computed tomography examination and the blood ROS level. Therefore, we wish to conduct this study to clarify if the routinely applied abdominal X-ray computed tomography examination may induce a higher level of ROS in the peripheral blood. Study subjects will be patients who are admitted to our hospital because of abdominal diseases that need to receive abdominal X-ray computed tomography examination for diagnosis. In total, sixty cases will be enrolled for the study. The formal consent will be delivered and explained to the patients and families several hours before the performance of abdominal X-ray computed tomography. The formal consent will be retrieved and then the peripheral blood will be sampled just before the performance of computed tomography.ROS level in the sampled peripheral blood, before and after the performance of abdominal X-ray computed tomography, will be measured, compared, and analyzed. Totally 120 blood samples, including 60 samples just before and 60 samples 2 hours after the performance of computed tomography, will be collected from 60 study subjects within 5 months (August 10 ~ December 30, 2008). Reactive oxygen species（ROS）levels will be measured by a chemiluminescence (CL) analysing system (CLD-110, Tohoku Electronic Industrial, Sendai, Japan).
The purpose of this study is to compare postprandial distress syndrome and epigastric pain syndrome in demographics psychological features, infection of Helicobacter pylori, gastric emptying and therapeutic response to lansoprazole.
Originally test host's to understand the tracking healthily and immune change of the dengue fever in Taiwan. Blood drawing 20 c.c for liver examination, kidney and other biochemical function, analyze host immunity adjusts and controls the gene, and the reciprocation that may be produced with the virus hepatitis, besides collected 10 c.c urine at the same time. Urine check is in order to compare acute infect and infected over three month person, the change of chemical composition. This plan expect to collect 150 healthy, 150 dengue fever infected and 150 dengue fever bleed hot or dengue fever shock disease group's patient, goal to understand health state and immunity of follow-up adjust and control the difference of the gene and the reciprocation may produce to virus hepatitis of light disease and serious disease.
Phase advance of HRV will be anticipated in agomelatine group. It is anticipated that both agomelatine and floxentine will increase HRV at the end of the treatment.
Primary Objective: - The primary objective is to evaluate the efficacy of photodynamic therapy in the treatment of malignant intracranial tumors. Secondary Objective: - The secondary objective is to evaluate the safety of photodynamic therapy in the treatment of malignant intracranial tumors.
This study aims to conduct a cost-effectiveness analysis (CEA) among the programs for preventing osteoporotic fracture. The main comparison will be made among the effects of three programs for preventing osteoporotic fractures: 1. health education; 2. exercise intervention for enhancing bone mineral density (BMD); 3. exercise intervention for preventing falls. The "cost" will be measured bases on the monetary cost of implementation of each program. The "effectiveness" will be measured includes the number of prevented osteoporotic fractures of each program, and related outcomes are the follows: 1. the medical cost of osteoporotic fracture; 2. the change of BMD in consecutive years; 3. the quality of life (QOL) of patients with osteoporotic fracture as compared to the reference population.
We have identified insulin-like growth factor binding protein (IGFBP)-3 as an invasion suppressor gene in ovarian endometrioid carcinoma, and showed association with lower cancer migration, invasion and metastasis. Recently, a novel model of ovarian EC formation from endometriosis was reported, and PTEN was found to be a major protein involved. Inactivation of PTEN has been reported in some ovarian EC tumors and methylation was suggested as one of the major epigenetic changes. This tumorigenesis model has lots of similarity to our established invasion model. Therefore, we plan to study the important of PTEN expression in ovarian EC and if inactivation of PTEN and IFGBP-3 is through methylation. Furthermore, by studying the signal transduction pathways using PTEN and IGFBP-3 transfection, we plan to study the mutual interaction between PTEN and IGFBP-3 on the suppression of tumor invasion in ovarian EC.
