The Global Emergence of a Scientific Field: Precision Medicine in ChinaAu, Larry January 2022 (has links)
Precision medicine is defined as the use of genomics and big data approaches to health to better tailor the diagnosis and treatment of disease to patients. Precision medicine was conceived in the National Research Council’s 2011 report Towards Precision Medicine and was picked up by the Obama Administration in its 2015 launch of the Precision Medicine Initiative. Central to this is the All of Us Research Program, which seeks to sequence the genomes and conduct a longitudinal study of 1 million individuals to advance knowledge about various health outcomes. Precision medicine has been taken up by governments and organizations around the world, notably in China, where the term was incorporated in national plans in 2016 such as the 13th Five Year Plan and Healthy China 2030. Precision medicine became a “key strategy”, and a large amount of funding was pledged to finance the start of precision medicine projects at a range of research organizations, such as the Chinese Academy of Sciences and BGI.
My dissertation investigates why precision medicine attracted the attention of scientists, policymakers, and clinicians in the 2010s. It also traces how the precision medicine bandwagon gained so many allies globally, and what precision medicine means for stakeholders located at different positions in the emerging field. To answer these questions, I apply the concepts of global field and scientific capital to trace the emergence of precision medicine at the global and national levels. My argument analytically distinguishes between global scientific capital and national scientific capital in order to show how varying combinations of scientific capital orients actors towards different goals and priorities of precision medicine. More generally, I demonstrate how hybrids and “off-label” forms of science appear in the process of scientific globalization.
In the introduction of the dissertation, I look to Bourdieu’s writing on scientific fields to lay out my theoretical framework of fields and capitals as it applies to global science. The dissertation is then organized into three substantive chapters. In Chapter 1, I trace the emergence of the global field of precision medicine drawing on two sources of data: first, a bibliometric analysis of scientific publications in precision medicine, and a further analysis of the key institutions and actors behind its global push. This chapter charts the contours of the global scientific field of precision medicine and the logics of accruing global scientific capital.
In Chapter 2, I examine the differentiation of the national field of precision medicine in China from the global field, and trace the logics of accumulation for a national scientific capital. In this chapter, I draw on documentary analysis to tell the recent history of genomics in China, as well as interviews with scientists and participant observation of scientific conferences. In doing this, I shed light on two hybrid forms of precision medicine in China: Chinese Precision Medicine or the use of genomics to identify “Chinese DNA” and to cure “Chinese diseases”, and Precision Chinese Medicine or the use of genomics to open the “black box” of traditional Chinese medicine.
In Chapter 3, I take the case of genetic talent testing in China to show how precision medicine is understood by the public. Making use of social media data, and a content analysis of news articles and marketing material, I argue against the “deficit model” of science used to paint parents who use genetic talent tests as scientifically illiterate. Instead, I show how this “off-label” use of genomics responds to broader social, political, and economic pressures of parenting in contemporary China, and argue that scientific capital continues to shape the circulation of genetic talent testing as it encounters the public. I conclude with notes on how the imaginary of precision medicine is affecting the practice of precision governance in China and observations of how the ongoing U.S.-China uncoupling may shape global science.

Mechanistic study on the intestinal absorption, metabolism, and disposition of baicalein. / CUHK electronic theses & dissertations collectionJanuary 2006 (has links)
Aim. Baicalein is a bioactive flavonoid component isolated from the root of Scutellaria baicalensis, which has been used as a traditional Chinese medicinal herb for the treatment of inflammation for centuries. Although various pharmacological effects of baicalein have been demonstrated, only limited studies in rats reported pharmacokinetic of baicalein, which exhibited a low oral bioavailability due to extensive first-pass metabolism. In addition, no investigation on human oral absorption or metabolic kinetic profile was reported previously. The current project conducted a series of mechanistic studies aiming to elucidate the intestinal absorption, metabolism and disposition of baicalein. Since glucuronidation plays an important role in the first-pass metabolism of flavonoids including baicalein, additional studies on the relationship between human intestinal glucuronidation activities and chemical structures of flavonoids have also been performed. / Conclusion. Baicalein is well absorbed at intestine but subjected to extensive intestinal glucuronidation resulting in low oral bioavailability. The glucuronidation of baicalein is catalyzed by multiple UGT isozymes. The disposition of baicalein 7-O-glucuronide, the major metabolite of baicalein in vivo, is mediated by the MRP and OATP transporters. The nucleophilicity and stereo-conformation of -OH substituents are crucial for the intestinal glucuronidation of flavonoids. / Methods. For investigation on intestinal absorption, metabolism and disposition of baicalein, human Caco-2 cell monolayer model, rat in situ intestinal perfusion model, and in vitro metabolism model were employed in the present study. For the further investigation on the position preference on glucuronidation of flavonoids at human intestine, the in vitro rates of glucuronidation among seven commercially available mono-hydroxyflavones, namely 3-, 5-, 6-, 7-, 2'-, 3'- and 4'-mono-hydroxyflavones were determined and compared. / Results. The satisfactory permeabilities of baicalein obtained from both Caco-2 cell model and rat intestinal perfusion model indicated its potential good absorption at gastrointestinal tract. Therefore, absorption should not be the rate-limiting factor causing the low oral bioavailability of baicalein. However, extensive glucuronidation occurred in the rat intestine perfusion model with over 90% of baicalein being metabolized after intestinal absorption. Consistent findings were also observed in the in vitro enzyme kinetic studies of baicalein. The biotransformation of baicalein to baicalein 7-O-glucuronide was extensive in human liver microsome, human jejunum microsome, rat liver microsome, and rat jejunum microsome with intrinsic clearances (Vmax/Km) of 618, 446, 436, 298 mul/min/mg, respectively, which are orders of magnitude greater than those of most of western drugs that share the same metabolic pathway. Further enzyme kinetic studies using human recombinant glucuronosyltransferases (UGT) isozymes showed that UGT 1A1, 1A3, 1A8, 1A9, 1A7 and 2B15 were involved in the glucuronidation of baicalein with different kinetic profiles. Mechanistic studies on the disposition of baicalein 7-O-glucuronide formed from a rapid glucuronidation of baicalein in intestine demonstrated that this intracellularly formed glucuronide of baicalein could be actively extruded to both the apical and basolateral sides (the so called efflux) in Caco-2 cell model as well as rat intestinal perfusion model. It was also found that the efflux of the baicalein 7-O-glucuronide followed saturable enzyme kinetics and was effectively inhibited by multi-drug resistance associated proteins (MRP) and organic anion transporters (OATP) inhibitors. Further study on the relationship between flavonoid structures and glucuronidation activities using seven monohydroxyflavones demonstrated that the conjugation rates of 6- and 3'-monohydroxyflavones (HF) were much greater than those of 3-, 4'-, 7-, 2'-HF, while 5HF was the lowest. / Zhang Li. / "August 2006." / Advisers: Zhong Joan Zuo; Ge Lin. / Source: Dissertation Abstracts International, Volume: 68-03, Section: B, page: 1587. / Thesis (Ph.D.)--Chinese University of Hong Kong, 2006. / Includes bibliographical references (p. 186-223). / Electronic reproduction.

Effects of a kidney-tonifying herbal formula on Type I osteoporosis. / CUHK electronic theses & dissertations collectionJanuary 2009 (has links)
A pilot clinical trial was conducted after the in-vivo and in-vitro studies: Eight subjects fulfilled the inclusion criteria were recruited. However, the liver function tests of three subjects out of eight were found to be abnormal with elevated aspartate aminotransferase (AST) and alanine aminotransferase (ALT) level, which was not reported in previous toxicity test. The trial was suspended immediately and a follow-up test showed that the elevated AST and ALT level had reverted back to normal within one month after termination of OPR intake. Although we could not accomplish a RCT, the pilot study revealed potential hepatotoxicity of OPR on human beings and it would raise the safety awareness of investigators on the use of herbal remedies in future clinical studies. / After the in-vivo and in-vitro studies, a double-blinded, randomized, placebo-controlled clinical trial (RCT) was planned. Due to a lack of a Chinese version of instrument to measure osteoporosis-specific quality of life, an English version of the Osteoporosis-Targeted Quality of Life Questionnaire (OPTQoL) was translated into Chinese and linguistically validated according to the standard guideline. The newly formed Chinese OPTQoL can be used to assess the impact of new interventions on quality of life among Chinese osteoporosis patients. / Association of the incidence of postmenopausal osteoporosis and Kidney-Vacuity Syndromes in TCM was investigated with the aid of a Kidney-Vacuity Syndromes scoring questionnaire. In the study, postmenopausal women, who suffered from deficiency of kidney "qi" and kidney "essence", had a significantly higher incidence of osteoporosis. These findings strongly supported that replenishing kidney qi and kidney essence was a logical therapeutic principle in the formulation of OPR. / In conclusion, this study investigated the use of TCM on the treatment of postmenopausal osteoporosis in a systematic manner. It started from herbal formulation, basic science studies to clinical trial. It revealed beneficial effects of OPR on bones through in-vivo and in-vitro studies and demonstrated certain possible mechanism behind. On the other hand, the hepatotoxicity of OPR on human beings was also exposed and had not been reported in previous toxicity tests. The study provided valuable clinical data for other investigators on the potential hazards of herbal remedies although they had been validated as safe and effective in pre-clinical stage. / In search for safe, effective and low-priced medicine, the public have turned their attention to Traditional Chinese Medicine (TCM). Extensive experience has been accumulated in TCM regarding the diagnosis and treatment of osteoporosis, which often involves the prescription of kidney-tonifying herbs. Therefore, the aim of the study, firstly, was to explore the association of the incidence of postmenopausal osteoporosis and Kidney-Vacuity Syndromes in TCM, so as to formulate a rational kidney-tonifying herbal formula for osteoporosis research (OPR). Secondly, the effect of the formula was evaluated by in-vitro and in-vivo studies. Thirdly, the Osteoporosis-Targeted Quality of Life Questionnaire was linguistically validated from English to Chinese, which was expected to be one of the outcome measurement tools in future clinical trials. Lastly, a pilot clinical study was performed, which revealed some potential hazards of the formula on human beings which have not been shown in previous works. / Osteoporosis is a skeletal disorder which leads to an increased risk of bone fracture, disability or even death. It has become a major public health threat and the worldwide incidence of osteoporotic fracture is projected to increase two fold within the next 50 years. Postmenopausal women, being affected by a lack of estrogen, face a much higher risk of the disease. This study would therefore focus on type I osteoporosis (i.e. postmenopausal osteoporosis). Although current medications can slow down the bone deterioration process, their side effects and high cost had impaired patients' compliance with long term treatment. / The effect of OPR for the treatment of postmenopausal osteoporosis was then evaluated by in-vitro and in-vivo studies. In the in-vivo study, an osteoporosis model was established by performing ovariectomy on the four-week-old C57BL/6 mice. A high bone turnover rate was induced and OPR successfully slowed down the high turnover rate of bones by decreasing bone formation and resorption process without increasing the uterine linings. However, its beneficial effect on bones could not be detected on bone mineral density measurement. / The potential mechanism of action of OPR on bones was explored by in-vitro study. OPR was shown to induce cell proliferation and differentiation of osteoblast-like UMR 106 cells. Furthermore, the estrogenic activity of OPR was detected by MCF-7 cell line, which has been stably transfected with estrogen responsive elements (ERE). OPR was shown to possess an estrogenic activity in a dose dependent manner and was comparable to the positive control at a concentration of 200 and 1000 mug/ml. The induced estrogenic activity by OPR may be associated with the presence of phytoestrogen within the herbal formula. These findings suggested that the beneficial effect of OPR on bones might relate to its direct positive effect on osteoblast and its estrogenic-like activity. / Liong, Ching. / Adviser: Chun-tao Che. / Source: Dissertation Abstracts International, Volume: 73-03, Section: B, page: . / Thesis (Ph.D.)--Chinese University of Hong Kong, 2009. / Includes bibliographical references (leaves ). / Electronic reproduction.
