養龍神話的魔幻化重寫 : 讀也斯 \u3c養龍人師門\u3e

在香港，也斯被評為可能是最早譯介當代拉丁美洲小說的譯者，也可能是最早發表帶魔幻色彩的小說的作者。〈養龍人師門〉帶有濃厚的魔幻寫實主義的色彩，業界自然不乏以魔幻寫實主義分析也斯作品，然而似乎只把魔幻寫實視為創作技法，片面理解魔幻寫實主義，忽略其背後的精神。本文嘗試結合學者研究魔幻寫實主義的成果，旁借也斯訪談錄，分析也斯在〈養龍人師門〉如何用魔幻寫實主義重寫神話。本文核心主要是環繞以下兩個問題： 1. 也斯為養龍神話加入／重寫了不少情節和細節，這些故事新質有何意義？ 2. 也斯如何以魔幻手法處理重寫，並體驗了怎樣的魔幻寫實主義的特色？ 為行文方便，本文將「受魔幻寫實主義影響」、「經過魔幻寫實主義的手 法處理」縮寫成「魔幻化」

Facilitating Change in School Health: A Qualitative Study of Schools’ Experiences Using the School Health Index

Introduction: As school-based efforts increase to address the epidemic of childhood obesity, a priority for health professionals and educators will be to identify effective tools appropriate for use in schools to help guide health promotion programs and policies. This article describes the results of a qualitative research study examining school staff and community members' experiences working with the Centers for Disease Control and Prevention's School Health Index, a self-assessment and planning tool that addresses nutrition and physical activity. Methods: In-depth interviews were carried out with faculty, staff, and community collaborators in nine public schools that were using the School Health Index to develop nutrition and physical activity initiatives for students. Interviews were conducted twice: once after a school had completed the School Health Index and once approximately 1 year later. Transcript data from interviews with 34 participants were analyzed using thematic analysis. Results: Findings indicated that school experiences differed markedly depending on whether they received help from an outside facilitator to work with the School Health Index. Unlike staff in schools working on their own, school staff working with outside facilitators described completing the School Health Index in a collaborative way, creating action plans, and working as a team to implement health promotion initiatives. In addition, the involvement of an outside facilitator supported schools in undertaking more complex tasks with a greater degree of collaboration across the school and local communities in order to achieve goals. Conclusion: Outside facilitators may significantly enhance schools' efforts to work with the School Health Index and influence the organizational strategies they use to implement health promotion initiatives

Hematopoietic stem cell quiescence and DNA replication dynamics maintained by the resilient β-catenin/Hoxa9/Prmt1 axis

Maintenance of quiescence and DNA replication dynamics are two paradoxical requirements for the distinct states of dormant and active hematopoietic stem cells (HSCs), which are required to preserve the stem cell reservoir and replenish the blood cell system in response to hematopoietic stress respectively. Here, we show that key self-renewal factors, β-catenin or Hoxa9, largely dispensable for HSC integrity in fact have dual functions in maintaining quiescence and enabling efficient DNA replication fork dynamics to preserve the functionality of hematopoietic stem and progenitor cells (HSPCs). While β-catenin or Hoxa9 single knockout (KO) exhibited mostly normal hematopoiesis, their co-inactivation led to severe hematopoietic defects stemmed from aberrant cell cycle, DNA replication and damage in HSPCs. Mechanistically, β-catenin and Hoxa9 function in a compensatory manner to sustain key transcriptional programs that converge on the pivotal downstream target and epigenetic modifying enzyme, Prmt1, which protects the quiescent state and ensures an adequate supply of DNA replication and repair factors to maintain robust replication fork dynamics. Inactivation of Prmt1 phenocopied both cellular and molecular phenotypes of β-catenin/Hoxa9 combined KO, which at the same time could also be partially rescued by Prmt1 expression. The discovery of the highly resilient β-catenin/Hoxa9/Prmt1 axis in protecting both quiescence and DNA replication dynamics essential for HSCs at different key states provides not only novel mechanistic insights into their intricate regulation but also a potential tractable target for therapeutic intervention

Clinical practice guidelines and real-life practice on hepatocellular carcinoma: the Hong Kong perspective

Hepatocellular carcinoma (HCC) is a major public health burden in Hong Kong, and chronic hepatitis B is the most common HCC etiology in our region. With the high case load, extensive local expertise on HCC has been accumulated. This article summarized local guidelines and real-life practice on HCC management in Hong Kong. For HCC surveillance, liver ultrasound and serum alpha-fetoprotein for periodic screening is recommended in viral hepatitis or cirrhotic patients, and this is adhered to in clinical practice. HCC diagnosis is not covered in local guidelines, yet our practice is in-line with regional guidelines, where diagnosis is usually achieved by cross-sectional imaging and without the need for histology. Our guidelines recommend using the Hong Kong Liver Cancer Staging for pre-treatment staging, yet we routinely use other widely-adopted systems such as the Barcelona Clinic Liver Cancer Staging and the Tumor-Node-Metastasis Staging as well. Our local guidelines have provided clear treatment algorithms for the whole range of HCC therapies, including resection, ablation, transplant, transarterial chemoembolization, transarterial radioembolization, stereotactic body radiation therapy, targeted therapy, and immunotherapy. Real-life treatment choices are largely in line with the guidelines, although treatment protocols are individualized, and availability of specific therapies can vary between centers. Overall, HCC guidelines in Hong Kong are tailored based on local expertise and our unique patient population. The guidelines are up-to-date and provide practical pathways to assist our routine practice. Regular updates of local guidelines are warranted to account for the rapidly evolving paradigm of HCC management

Genome-Wide Association Study of Hepatocellular Carcinoma in Southern Chinese Patients with Chronic Hepatitis B Virus Infection

One of the most relevant risk factors for hepatocellular carcinoma (HCC) development is chronic hepatitis B virus (HBV) infection, but only a fraction of chronic HBV carriers develop HCC, indicating that complex interactions among viral, environmental and genetic factors lead to HCC in HBV-infected patients. So far, host genetic factors have incompletely been characterized. Therefore, we performed a genome-wide association (GWA) study in a Southern Chinese cohort consisting of 95 HBV-infected HCC patients (cases) and 97 HBV-infected patients without HCC (controls) using the Illumina Human610-Quad BeadChips. The top single nucleotide polymorphisms (SNPs) were then validated in an independent cohort of 500 cases and 728 controls. 4 SNPs (rs12682266, rs7821974, rs2275959, rs1573266) at chromosome 8p12 showed consistent association in both the GWA and replication phases (ORcombined = 1.31–1.39; pcombined = 2.71×10−5–5.19×10−4; PARcombined = 26–31%). We found a 2.3-kb expressed sequence tag (EST) in the region using in-silico data mining and verified the existence of the full-length EST experimentally. The expression level of the EST was significantly reduced in human HCC tumors in comparison to the corresponding non-tumorous liver tissues (P<0.001). Results from sequence analysis and in-vitro protein translation study suggest that the transcript might function as a long non-coding RNA. In summary, our study suggests that variations at chromosome 8p12 may promote HCC in patients with HBV. Further functional studies of this region may help understand HBV-associated hepatocarcinogenesis
