Prevalence of SFTSV among Asian House Shrews and Rodents,China, January–August 2013

To evaluate the role of small mammals as hosts of severe fever with thrombocytopenia syndrome virus (SFTSV), we tested serum samples from rodents and shrews in China, collected in 2013. SFTSV antibodies and RNA were detected, suggesting that rodents and shrews might be hosts for SFTSV.     

Factors associated with lower quality of life among patients receiving palliative care

Title.  Factors associated with lower quality of life among patients receiving palliative care.
Aim.  This paper is a report of a study conducted to (1) assess the quality of life (QoL) and physical functioning status of patients diagnosed with advanced cancer and receiving palliative care; (2) determine if there was a statistically significant relationship between their physical functioning and QoL and (3) identify the demographic and disease-related variables related to their QoL.
Background.  Achieving the best possible QoL is a major goal in palliative care. However, research findings about the relationship between QoL and demographic variables have been inconsistent.
Method.  Three hundred patients with advanced cancer were recruited from four district hospitals in Hong Kong between February 2005 and July 2006. Their QoL and physical functioning status were assessed by face-to-face interview, using the McGill Quality of Life Questionnaire (Hong Kong version) and the Palliative Performance Scale respectively.
Results.  Participants reported reduced ambulation, inability to perform hobbies or housework, and the need for occasional assistance in self-care (mean: 64·6 out of 100, sd : 19·3, range: 20–100). QoL was fair (mean: 6·2 out of 10, sd : 1·5, range: 0·9–10). There was a weak positive association between physical functioning and QoL scores. Multiple regression analysis showed that patients who were older, female, had ever been married, or had higher physical functioning tended to have better QoL.
Conclusion.  More could be done in symptom and psychosocial management to improve patients' QoL, in particular for those who are younger, male or single, or who have lower physical functioning.     

Undocumented Migrants Reintroducing COVID-19, Yunnan Province,China

To limit the spread of severe acute respiratory syndrome coronavirus 2, the government of China has been monitoring infected travelers and minimizing cold-chain contamination. However, other factors might contribute to recurring outbreaks. We analyze the role of undocumented migrants as potential transmitters of severe acute respiratory syndrome coronavirus 2 in China.     

体部立体定向放疗的放射生物学研究进展

近年来,体部立体定向放疗(SBRT)被越来越多地应用于治疗各种实体肿瘤,并获得了显著的疗效。图像引导系统和放疗技术的进步,使SBRT在靶区内形成高剂量区域,靶区外剂量梯度迅速下降,在给予肿瘤大剂量照射的同时又尽可能地保护周围正常组织,实现了安全的“大分割”。目前,对于SBRT放射生物学尚缺乏规律性的认识,如线性二次(LQ)模型的适用性、再氧合的弱化、不同于常规分割放疗的额外细胞杀伤效应以及免疫增强作用等方面仍存有争议。本综述旨在对以上争议进行分析和探讨,以期加深对SBRT放射生物学特征的认识,进一步促进SBRT的临床应用。     

Clinical characteristics of acute ischemic syndrome in China

目的：研究分析中国地区急性心肌缺血综合征病人的临床特点和治疗现状。方法：此项研究为国际多中心关于急性心肌缺血综合征登记经验（OASIS）的一部分。采用填写加拿大心血管合作协会统一设计的病例记录表（CRF）的方法,自1999年4月开始,收集了各中心因急性心肌缺血入院病人的资料,记录了病人主要临床特征和院内事件。结果：共注册急性心肌缺血综合征（包括不稳定心绞痛及非Q波心肌梗死）病人1509例,来自全国范围内34所医院。病人平均年龄62.3岁,其中男性62.2％,就诊时持续胸痛47.8％,心电图异常89.5％,入院诊断不稳定心绞痛91.3％,非Q波心肌梗死8.7％。住院期间溶栓3.3％,冠状动脉造影35.0％,经皮冠状动脉腔内成形术（PTCA）16.8％,冠状动脉旁路移植术（CABG）4.1％,应用硝酸酯制剂96.8％,抗血小板治疗95.5％。院内发生重要并发症18.8％,其中死亡1.2％,主要原因为严重心律失常或猝死。结论：中国地区急性心肌缺血病人以不稳定心绞痛就诊居多。我国病人住院期间PTCA治疗率相对较高,CABG治疗率较低。院内死亡最主要的原因为严重心律失常或猝死。
