Pharmacokinetics,distribution,and excretion of sodium oligomannate,a recently approved anti-Alzheimer's disease drug in China / 药物分析学报

The National Medical Products Administration has authorized sodium oligomannate for treating mild-to-moderate Alzheimer's disease.In this study,an LC-MS/MS method was developed and validated to quantitate sodium oligomannate in different biomatrices.The plasma pharmacokinetics,tissue distri-bution,and excretion of sodium oligomannate in Sprague-Dawley rats and beagle dogs were system-atically investigated.Despite its complicated structural composition,the absorption,distribution,metabolism,and excretion profiles of the oligosaccharides in sodium oligomannate of different sizes and terminal derivatives were indiscriminate.Sodium oligomannate mainly crossed the gastrointestinal epithelium through paracellular transport following oral administration,with very low oral bioavail-ability in rats(0.6％-1.6％)and dogs(4.5％-9.3％).Absorbed sodium oligomannate mainly resided in circulating body fluids in free form with minimal distribution into erythrocytes and major tissues.So-dium oligomannate could penetrate the blood-cerebrospinal fluid(CSF)barrier of rats,showing a con-stant area under the concentration-time curve ratio(CSF/plasma)of approximately 5％.The cumulative urinary excretion of sodium oligomannate was commensurate with its oral bioavailability,supporting that excretion was predominantly renal,whereas no obvious biliary secretion was observed following a single oral dose to bile duct-cannulated rats.Moreover,only 33.7％(male)and 26.3％(female)of the oral dose were recovered in the rat excreta within 96 h following a single oral administration,suggesting that the intestinal flora may have ingested a portion of unabsorbed sodium oligomannate as a nutrient.

Advances in diagnosis of gastrointestinal stromal tumor / 中国基层医药

Gastrointestinal stromal tumor(GIST) is the most common mesenchymal tumor in the digestive system, with potential malignant tendency.With the change of living habits and the update of instruments and equipments, the morbidity and detection rate of GIST have been increased year by year, attracting much attention.However, its clinical manifestations are not characteristic.At present, primary diagnosis is mainly made by imaging techniques such as CT and MRI, and pathological diagnosis is the gold index.In recent years, with the development of immunohistochemical technology and gene technology, immune markers and gene detection play an increasingly important role in the diagnosis of GIST.This paper reviews the progress of GIST diagnostic techniques.

CONCLUSIONS:Adjuvant arthritis can affect the pharmacokinetics of triptolide in rats in vivo,and promote its absorption and removal.

Through a spiritual lens: early childhood inclusive education in Hong Kong.

The main purpose of this research was to explore early childhood education teachers', principals', and parents' perceptions of the role of spirituality in the lives of children with special needs, and how educators and schools can support the spiritual development of these children. Three preschools, the Buddhist, Christian, and Waldorf schools, were purposefully selected on the basis that each of them reflects a philosophy that includes the spiritual. Three themes emerged from the data analysis: (a) the influence of the schools' religion and/or spiritual orientations on inclusion; (b) support provided for the spiritual development of children with special needs; and (c) the role of spirituality in the lives of children with special needs. By drawing attention to and offering a preliminary study on early childhood inclusion and spirituality, I hope to encourage more scholars and educators to engage with research and debate on this important yet under-studied dimension of early childhood education.

A comparison on inclusive practices for children with special needs in faith-based kindergartens in Hong Kong.

This qualitative study aimed to examine the inclusive practices implemented in three faith-based kindergartens in Hong Kong. A questionnaire was used to collect information about school backgrounds, students' special needs, teacher training, special education services, curriculum design, school policy, parental involvement, and challenges faced by these schools when implementing their inclusive practices. The primary focus of this study was the influence of faiths on the provision of inclusive services for children with special needs. The results indicated that faiths, along with other factors, have played a significant role in contributing to the inclusive education services provided to children in these schools.

Quest for a good life: spiritual values, life goals, and college students.

INTRODUCTION: Values and life goals are associated with one's general well-being and quality of life. However, there is insufficient documentation about issues that are linked with the notions of spiritual values and life goals among college students in Asia. This study addressed this lack of research by focusing on the spiritual values and life goals among students in Singapore. METHODS: Four hundred and ninety structured surveys and 64 follow-up interviews were taken in two government-sponsored universities in Singapore. RESULTS: Statistics showed that spiritual values were positively correlated with intrinsic goals, which had been shown to strongly relate to subjective well-being (SWB). DISCUSSION: Developing spiritual values may promote subjective well-being by enabling college students to find meaning and purpose in life.

Personal spiritual values and quality of life: evidence from Chinese college students.

Values are guiding principles in our life. While some studies found spiritual values to be "healthier," Sagiv and Schwartz (Eur J Soc Psychol 30:177-198, 2000) showed that people holding non-spiritual values were higher on affective well-being. We examined the predictive power of these two types of values with a longitudinal data set collected from Chinese students mainly in Hong Kong. Structural equation modeling revealed that spiritual values (as well as family income) positively predicted quality of life a year later. Non-spiritual, self-enhancement values, did not show any association. Results suggest that developing spiritual values may promote well-being through enabling individuals to find meaning and purpose in life.

What I look like: college women, body image, and spirituality.

Despite public acknowledgment of the importance of spiritual development, little has been written globally on female young adults' personal views of their spiritual values and body image. This article briefly presents the findings of a pilot study that explored female college students' reflections on body image and spirituality. Responses from participants showed that (1) many students are interested in faith and spiritual development; (2) body dissatisfaction affects those women who viewed themselves as spiritual (92%) as well as those who said they were free thinkers (49%). Nevertheless, religion and spiritual values seemed to confer some behavioral protection. Implications for educational programs that will address the spiritual dimension of learning are discussed.
