In this mini-review,we summarize recent findings relating to the prion-like propagation ofα-synuclein(α-syn)and the development of novel therapeutic strategies to target synucleinopathy in Parkinson’s disease(PD).We link the Braak’s staging hypothesis of PD with the recent evidence from in-vivo and in-vitro studies for the prion-like cell-to-cell propagation ofα-syn(via exocytosis and endocytosis).The classical accumulation of aggregatedα-syn in PD may result from an increased production or a failure in the mechanisms of clearance ofα-*** discuss novel agents,currently in clinical trial for PD including the ones that impact the aggregation ofα-syn and others that interfere withα-syn endocytosis as a means to target the progression of the disease.

诗词歌赋是传统中国戏曲中的特色之一,其美学乃从古到今熔铸了方言与地域文化的智慧结晶。这些中国戏曲中很多都有相关的电影版本,在香港尤其多;当时因应社会需要,这种戏曲电影中有一部分是配有中英文双语字幕的。由于古典诗词较晦涩难懂,这样一来,字幕英译不仅可以把诗化的唱词和对白内容更清晰地展示出来,也能更容易抓住观众的注意力。其中有一些中国戏曲的唱词已经翻译成英语,可惜并非所有的译本都能达到诗歌语感的共鸣。其实,以电影英文字幕形式出现的戏曲曲词,更是寥寥可数,这极可能是因为译者在平衡双语的文化语感和弦外之音方面感到吃力。故此,在把戏曲电影中的唱词翻译为英文字幕时,翻译者必须成为多元文化的桥梁——文化意蕴较重的元素必须顾及之余,又不可丢失字幕与戏曲文本的特定格式。修辞意象、内蕴意涵、着重诗意的翻译缺一不可,因为翻译者也如作者一样,是艺术家。本文会以著名的粤剧戏曲电影《紫钗记》为例,探索英译戏曲电影字幕中的诗化语言问题。

Laboratory class is very important in the education of hydraulic mechanics. However, it usually requires a high expenditure on equipment purchase and maintenance. Virtual equipment that renders the equipment in a virtual world and provides an interactive interface for users can be an ideal solution to reduce costs. In this research, we focus on developing virtual equipment for a Venturi tube experiment. We em-ployed multiple paper-prototypes to gather user feedback on the preliminary design. Following the final pro-totype, we then implemented the virtual equipment on computers. Interactive functions have been built into the virtual equipment. Users are able to manipulate the equipment and obtain real-time feedback as if they were using actual equipment. The results show that the development of the virtual equipment is technically feasible.

Background: Transarterial chemoembolization(TACE) is the most commonly used adjuvant therapy for hepatocellular carcinoma(HCC) after curative resection. Responses to TACE are variable due to tumor and patient heterogeneity. We had previously demonstrated that expression of Granulin-epithelin precursor(GEP) and ATP-dependent binding cassette(ABC)B5 in liver cancer stem cells was associated with chemoresistance. The present study aimed to evaluate the association between GEP/ABCB5 expression and response to adjuvant TACE after curative resection for HCC. Methods: Patients received adjuvant TACE after curative resection for HCC and patients received curative resection alone were identified from a prospectively collected database. Clinical samples were retrieved for biomarker analysis. Patients were categorized into 3 risk groups according to their GEP/ABCB5 status for survival analysis: low(GEP-/ABCB5-), intermediate(either GEP +/ABCB5-or GEP-/ABCB5 +) and high(GEP +/ABCB5 +). Early recurrence(recurrence within 2 years after resection) and disease-free survival were analyzed. Results: Clinical samples from 44 patients who had followed-up for more than 2 years were retrieved for further biomarker analysis. Among them, 18 received adjuvant TACE and 26 received surgery alone. Patients with adjuvant TACE in the intermediate risk group was associated with significantly better overall survival and 2-year disease-free survival than those who had surgery alone( P = 0.036 and P = 0.011, respectively). Adjuvant TACE did not offer any significant differences in the early recurrence rate, 2-year disease-free survival and overall survival for patients in low and high risk groups. Conclusions: Adjuvant TACE can only provide survival benefits for patients in the intermediate risk group(either GEP +/ABCB5-or GEP-/ABCB5 +). A larger clinical study is warranted to confirm its role in patient selection for adjuvant TACE.

目的:探讨对于因各种原因而未行淋巴清扫的早期卵巢癌患者,若不行二次分期手术,而是给予辅助化疗,其生存率是否会受影响。方法:收集1992年1月—2002年12月所有在香港玛丽医院妇产科就治的、因各种原因未接受淋巴清扫的、肉眼直视观察肿瘤局限于卵巢的Ⅰ期卵巢癌病例进行回顾性分析。结果:有81例患者被纳为研究对象,其中ⅠA期23例,ⅠB期1例,ⅠC期57例。年龄范围21～81岁,平均年龄47岁。随访时间50～179个月,平均随访时间为110个月。其中有64例(79.0%)患者接受了辅助化疗。总的5年生存率和4年无瘤生存率分别为91.4%和85.2%,与文献报道的行淋巴清扫后的结果相近。结论:对于未行淋巴清扫而病变局限于卵巢的Ⅰ期卵巢癌患者,若辅以适当的化疗,可以使她们获得与行淋巴清扫患者同样的生存率。
