Parathyroid hormone (PTH) may play an important role in the down-regulation of CYP3A4 expression induced by Chronic kidney diseases (CKD). In the study of molecular mechanism, the research group found that the expression of CYP3A2 metabolic enzyme in rat liver decreased in the state of CKD.And PTH may down-regulate the expression of CYP3A4 metabolic enzyme by inhibiting the expression of Nuclear factor- Kilobuse (NF-kB) p65 subunit

Mucosal healing or histological remission is an important target for the treatment of inflammatory bowel disease. In this study, patients with mucosal healing are defined as a control group, observing their clinical outcomes for 3 years, and describing the recurrence rate. The secondary objective is to study the operative rate, glucocorticoid utilization rate, treatment escalation rate, hospitalization rate and incidence of related complications.

Computed Tomography Derived Fractional Flow Reserve (CT-FFR) is a noninvasive method for evaluating the hemodynamic significance of coronary artery lesions by using coronary CT Angiography (CCTA) as opposed to invasive FFR examination under invasive coronary angiography. The purpose of the CT-FFR-CHINA study is to verify that the diagnostic performance of hemodynamically significant lesions by CT-FFR is superior than routine anatomic evaluation of diameter stenosis using CCTA alone using invasive FFR as the reference standard, exclusively in Chinese population.

Preterm infants are especially vulnerable to gut microbiota disruption and dysbiosis since their early gut microbiota is less abundant and diverse. Several factors may influence infants' microbiota such as mother's diet, mode of delivery, antibiotic exposure and type of feeding. The main goal of this observational study is to evaluate the impact of different types of feeding (breast milk, donor human milk and preterm formulas) on the intestinal microbiota of preterm infants hospitalized in the neonatal intensive care unit (NICU) of Maternidade Alfredo da Costa (MAC). Furthermore, the influence of mode of delivery and the mother's diet, among others factors, on vertical microbiota transmission will be evaluated. After delivery, mothers will be asked to collect their own fecal samples and will be invited to complete a semi-quantitative food frequency questionnaire. Stool samples will be collected from premature infants every 7 days. DNA will be extracted from fecal samples and different bacterial genus and species will be analyzed.

A cross-sectional quantitative study will be carried out; recruiting female, Caucasian participants aged 18-65 years. The relevance of candidate gene studies is disputed. Research has shown associations between genotype and total fat intake. However, food preference is often described as a result of exposure to food types during upbringing. Many single nucleotide polymorphisms (SNP) have been associated with fat taste sensitivity, the majority of research shows that with a reduced sensitivity comes a higher total fat consumption. This study aims to assess the relationship between rs1761667 genotype, body mass index, fat intake, fat taste sensitivity and fat taste preference.

Modified Right Lobe Graft(MRLG) is one of the most common used graft in liver transplantation .Anterior sector of allograft in MRLG usually congested to decrease this congestion tributaries of middle hepatic vein should be drained to inferior vena cava . There are too many techniques available for this drainage using either cryopreserved or synthetic graft for vascular anastomosis .In this study we will compare between two different technique using ringed synthetic polytetrafluoroethylene (PTFE) graft to assess outflow adequacy in both technique.

The diagnosis of chronic thromboembolic pulmonary hypertension (CTEPH) is difficult for numerous reasons and is related with a poor prognosis. In Taiwan, the incidence of CTEPH and its clinical features are unknown. This study aims at evaluating the prevalence, clinical characteristics, and management of CTEPH in a Taiwanese cohort. Primary objective: - To investigate the geodemographics of CTEPH in Taiwan Secondary objectives: To characterize the demographics and clinical presentation of patients with CTEPH To describe the real-world management and treatment outcome of patients with CTEPH To identify the risk factors of CTEPH To assess the relationship between risk factors/patients' characteristics and clinical outcomes for CTEPH To evaluate the prognosis of CTEPH in Taiwan using survival assessment

Specific oral microbiome has been found to contribute to the development of colorectal cancer. We speculate that specific oral microbiota related to colorectal cancer relapse after curative treatment. This study aim to discover if any difference of oral microbiota exist in patients who suffer from cancer relapse compared with patients who do not. Finally develop patient-centred programmes of surveillance protocols base on microbiota analysis.
