從感生神話推論契、后稷時期由母系社會過渡至父系社會之商榷

有論者謂感生神話反映了先民從母系社會過渡至父系社會，這主要是根據「玄鳥生商」和姜嫄「履大人跡」兩個感生神話，推論契、后稷時期的社會狀況。然而，此說法有商榷之處，故對這論調仍有所保留。 本文會先介紹感生神話的定義及分類，分類方面將會從觸物感生、意念感生，以及不同的感生媒介把感生神話分類，並援引神話作為例證。接著嘗試歸納支持契、后稷時期由母系社會過渡至父系社會此說法的理據，然後提出一己之見，並援引其他感生神話為例，說明此論調的不足之處和可斟酌之點。這部份將從三方面進行論述，包括感生神話中女性的主動性、感生神話所反映之母系社會特徵，以及父權話語體系下的感生神話

The Stories We Tell Influence the Support We Receive:Examining the Reception of Support-Seeking Messages on Reddit

Although social support facilitates coping and recovering from stressful life events, people do not always get the support that they need. Prior research suggests that the way one talks about stressful events to others may influence the support they receive. Given that people are increasingly relying on online communities for social support, this study adopted a person-centered approach (latent profile analysis) to examine how narrative variables related to the motivational themes, emotional content, and organizational structure of randomly sampled support-seeking messages ( N  = 495) posted on Reddit (r/Anxiety and r/Depression) influenced the quantity (number of comments and post score) and quality (type of support in comments) of support that they received. We identified five distinct narrative profiles of support-seeking posts, which in turn differentially predicted the quality, but not quantity, of social support people received. While commenters provided high levels of emotional support to all forms of posts, we found that coherence was an important determinant of esteem support. A combination of coherence, as well as agency and affective tone, were important determinants of instrumental, informational, and network support. The ways in which one talks about their problems influence the way others support them.</p

Projecting the 10-year costs of care and mortality burden of depression until 2032: a Markov modelling study developed from real-world data

Background Based on real-world data, we developed a 10-year prediction model to estimate the burden among patients with depression from the public healthcare system payer's perspective to inform early resource planning in Hong Kong. Methods We developed a Markov cohort model with yearly cycles specifically capturing the pathway of treatment-resistant depression (TRD) and comorbidity development along the disease course. Projected from 2023 to 2032, primary outcomes included costs of all-cause and psychiatric care, and secondary outcomes were all-cause deaths, years of life lived, and quality-adjusted life-years. Using the territory-wide electronic medical records, we identified 25,190 patients aged ≥10 years with newly diagnosed depression from 2014 to 2016 with follow-up until 2020 to observe the real-world time-to-event pattern, based on which costs and time-varying transition inputs were derived using negative binomial modelling and parametric survival analysis. We applied the model as both closed cohort, which studied a fixed cohort of incident patients in 2023, and open cohort, which introduced incident patients by year from 2014 to 2032. Utilities and annual new patients were from published sources. Findings With 9217 new patients in 2023, our closed cohort model projected the 10-year cumulative costs of all-cause and psychiatric care to reach US$309.0 million and US$58.3 million, respectively, with 899 deaths (case fatality rate: 9.8%) by 2032. In our open cohort model, 55,849–57,896 active prevalent cases would cost more than US$322.3 million and US$60.7 million, respectively, with more than 943 deaths annually from 2023 to 2032. Fewer than 20% of cases would live with TRD or comorbidities but contribute 31–54% of the costs. The greatest collective burden would occur in women aged above 40, but men aged above 65 and below 25 with medical history would have the highest costs per patient-year. The key cost drivers were relevant to the early disease stages. Interpretation A limited proportion of patients would develop TRD and comorbidities but contribute to a high proportion of costs, which necessitates appropriate attention and resource allocation. Our projection also demonstrates the application of real-world data to model long-term costs and mortality, which aid policymakers anticipate foreseeable burden and undertake budget planning to prepare for the care need in alternative scenarios

Happy farming programme : an exploratory study from an intergenerational perspective

Background: To extend the successful experience learnt from the Golden Organic Farming Programme in Tsuen Wan organized by Produce Green Foundation in 2004, a new farming programme entitled “Happy Farming” has been launched in Tuen Mun. A plot of land was leased to Good Tiding Church of Christian National’s Evangelism Commission in Lai Wai Tuen Mun (屯門泥圍佳音福音堂) by the Government. APIAS was invited to design and implement the farming programme in January 2005. Nine volunteers were recruited, including five older people and four youngsters to work together on farming activities including land exploitation, trainings, ploughing, weeding and mass activities such as opening day and harvest day so that intergenerational cooperation and communication could be promoted. By the experience where joint effort is needed, it is expected that the intergenerational programme could bring a certain amount of happiness to the participants. Objectives: In order to get a better understanding of the ways farming activities could enhance happiness of the participants and promote intergenerational relationships, an exploratory study on the impacts of farming will be investigated. To make it more specific, the research objectives are addressed as follows: To explore the way(s) of intergenerational cooperations and communications during farming activities; To investigate the association of farming activities towards the increase in happiness of the participants (the old and the young); To identify an effective programme intervention strategy to promote intergenerational support and psychological well-being (happiness) for policy makers

Overexpression of proto-oncogene FBI-1 activates membrane type 1-matrix metalloproteinase in association with adverse outcome in ovarian cancers

<p>Abstract</p> <p>Background</p> <p>FBI-1 (factor that binds to the inducer of short transcripts of human immunodeficiency virus-1) is a member of the POK (POZ and Kruppel) family of transcription factors and play important roles in cellular differentiation and oncogenesis. Recent evidence suggests that FBI-1 is expressed at high levels in a subset of human lymphomas and some epithelial solid tumors. However, the function of FBI-1 in human ovarian cancers remains elusive.</p> <p>Results</p> <p>In this study, we investigated the role of FBI-1 in human ovarian cancers, in particularly, its function in cancer cell invasion via modulating membrane type 1-matrix metalloproteinase (MT1-MMP). Significantly higher FBI-1 protein and mRNA expression levels were demonstrated in ovarian cancers samples and cell lines compared with borderline tumors and benign cystadenomas. Increased FBI-1 mRNA expression was correlated significantly with gene amplification (P = 0.037). Moreover, higher FBI-1 expression was found in metastatic foci (P = 0.036) and malignant ascites (P = 0.021), and was significantly associated with advanced stage (P = 0.012), shorter overall survival (P = 0.032) and disease-free survival (P = 0.016). <it>In vitro</it>, overexpressed FBI-1 significantly enhanced cell migration and invasion both in OVCA 420 and SKOV-3 ovarian carcinoma cells, irrespective of <it>p53 </it>status, accompanied with elevated expression of MT1-MMP, but not MMP-2 or TIMP-2. Moreover, knockdown of MT1-MMP abolished FBI-1-mediated cell migration and invasion. Conversely, stable knockdown of FBI-1 remarkably reduced the motility of these cells with decreased expression of MT1-MMP. Promoter assay and chromatin immunoprecipitation study indicated that FBI-1 could directly interact with the promoter spanning ~600bp of the 5'-flanking sequence of MT1-MMP and enhanced its expression in a dose-dependent manner. Furthermore, stable knockdown and ectopic expression of FBI-1 decreased and increased cell proliferation respectively in OVCA 420, but not in the p53 null SKOV-3 cells.</p> <p>Conclusions</p> <p>Our results suggested an important role of FBI-1 in ovarian cancer cell proliferation, cell mobility, and invasiveness, and that FBI-1 can be a potential target of chemotherapy.</p

Clinical and biomechanical outcome of minimal invasive and open repair of the Achilles tendon

Introduction: With evolutions in surgical techniques, minimally invasive surgical (MIS) repair with Achillon applicator has been introduced. However, there is still a lack of literature to investigate into the clinical merits of MIS over open surgery. This study aims to investigate the correlation between clinical outcome, gait analysis and biomechanical properties comparing both surgical methods.Materials and methods: A single centre retrospective review on all the consecutive operated patients between January 2004 and December 2008 was performed. Twenty-six patients (19 male and 7 female; age 40.4 ± 9.2 years) had experienced a complete Achilles tendon rupture with operative repair. Nineteen of the patients, 10 MIS versus 9 open repairs (13 men with a mean age of 40.54 ± 10.43 (range 23-62 yrs) and 6 women with a mean age of 45.33 ± 7.71 (range 35-57 yrs) were further invited to attend a thorough clinical assessment using Holz's scale and biomechanical evaluation at a mean of 25.3 months after operation. This study utilized the Cybex II isokinetic dynamometer to assess the isokinetic peak force of plantar-flexion and dorsiflexion of both ankles. The patients were also invited to return to our Gait Laboratory for analysis. The eight-infrared camera motion capture system (VICON, UK) was utilized for the acquisition of kinematic variables. Their anthropometric data was measured according to the Davis and coworkers' standard.Results: The mean operative time and length of hospital stay were shorter in the MIS group. The operative time was 54.55 ± 15.15 minutes versus 68.80 ± 18.23 minutes of the MIS group and Open group respectively (p = 0.045), whereas length of stay was 3.36 ± 1.21 days versus 6.40 ± 3.70 days respectively (p = 0.039). There is statistically significant decrease (p = 0.005) in incision length in MIS group than the open surgery group, 3.23 ± 1.10 cm versus 9.64 ± 2.55 cm respectively. Both groups attained similar Holz's scores, 11.70 ± 0.95 versus 12.0 ± 1.50 respectively (p = 0.262). The mean percentage stance time of the injured leg for MIS patient was 58.44% while the mean percentage stance time of the injured leg for patients with open repair was 56.57%. T-test has shown there were no significance differences between the results of the two groups of patients. The loss of peak torque and total work done with respect to the injured side were similar between the MIS and open group.Discussion and conclusion: MIS using Achillon method can achieve smaller incisions, shorter operative time and hospital stay. There is no statistical significance difference in clinical outcome, the stance time to strike time ratio and biomechanical properties on the leg receiving Achilles tendon repair using MIS method and open surgery. © 2011 Chan et al; licensee BioMed Central Ltd
