《本草图经》“牛皮胶制作不甚精”实验求证

《本草图经》记载:"牛皮胶制作不甚精。"为求证原因,笔者以北魏《齐民要术》所载煮胶法为基础,分别用鲜牛皮与牛皮鞋制作牛皮胶。结果显示,鲜牛皮制作的牛皮胶出胶率高,胶呈琥珀色,色泽明亮,拍之即碎,断面有玻璃茬,无腥秽气味;而用牛皮鞋制作的牛皮胶出胶率低,胶呈黑褐色,色泽晦暗,不易干燥,拍之难碎,断面无玻璃茬,有轻度腥秽气味。由于北宋的皮革业发展水平远远高于北魏时期,后者鞋履等旧皮多为未经过鞣制的生皮,前者则为经过鞣制的熟皮。因此,《本草图经》记载的"牛皮胶制作不甚精"真实原因可能是煮制过程中使用了充分鞣制过的熟牛皮。     

山东济宁某医院门诊患者幽门螺杆菌感染检测分析

目的探讨分析山东济宁地区自然人群幽门螺杆菌的流行病学特征,为防治提供参考。方法于2012-05/2013-05采集山东济宁市第一人民医院胃镜室就诊患者580例,采用14C-UBT检测法与血清幽门螺杆菌Ig G抗体ELISA法对所有研究对象的幽门螺杆菌感染情况进行检测,并结合相关问卷调查,分析其流行病学特征。结果该医院门诊患者幽门螺杆菌总感染率45.2%,其中男性感染率59.5%,女性感染率40.5%,不同性别感染幽门螺杆菌感染阳性率差异比较无统计学意义(P0.05);各年龄段幽门螺杆菌的感染率从31.4%~53.1%不等,农民、商人及工人幽门螺杆菌感染率分别为78.6%、70.7%、68.8%,高于其他职业,差异有统计学意义(P0.05),但各年龄段间幽门螺杆菌感染率的差异比较无统计学意义(P0.05)。幽门螺杆菌感染与吸烟、饮酒、家庭收入无关,差异无统计学意义(均P0.05),与个人饮食卫生习惯、家庭教育程度及职业有关,差异有统计学意义(P0.05)。结论山东济宁市某医院门诊患者幽门螺杆菌总感染率较高,其感染率与职业、个人及家庭生活习惯等有关。     

HIV-negative children’s experiences and opinions towards parental HIV disclosure: a qualitative study in China

In HIV/AIDS research, few studies to date have evaluated ways to improve parental HIV disclosure practices using feedback from HIV-negative children who have recently experienced this event. We conducted semi-structured in-depth interviews with 20 children (aged 6–15) who were partially to fully aware of their parents’ HIV status in rural Guangxi, China. Of the 20 children, eight children who were of older age (11.38 years in average) endorsed parental HIV disclosure, five discouraged it and seven expressed uncertainty. Children’s different experiences and attitudes towards disclosure were seen to be associated with their family dynamics (especially the parent–child relationship), social support and care, experiences of stigma and discrimination, psychosocial suffering, comprehension of the disease and the children’s age. Our study contributes to building a child-centered comprehensive understanding for Chinese parental HIV disclosure. It is imperative that counselors and community advocates assess and help parents achieve optimal readiness preceding disclosure of their illness to their HIV-negative children.     

双眼外直肌后徙术与常规疗法治疗斜视临床疗效比较

目的:比较双眼外直肌后徙术与常规疗法治疗斜视的临床疗效。方法:选取2016年6月-2017年6月笔者医院收治的128例斜视患者,按治疗方式不同分成对照组和研究组,每组各64例。其中对照组患者行常规单眼外直肌后徙联合内直肌缩短术(R&R),研究组患者行双眼外直肌后徙术(BLR-rec)。术后对患者随访1年,观察术后眼位正位率、欠矫率、过矫率,视觉功能恢复情况以及并发症发生率。结果:研究组患者正位率为89.06%高于对照组的68.75%,差异有统计学意义(P<0.05)。术前,对照组和研究组患者视近度、视远度和平均斜视度比较,两组患者融合功能和立体视功能占比比较,差异均无统计学意义(P>0.05)。术后,两组患者的斜视度较治疗前均出现了明显下降(P<0.05),且研究组治疗后斜视度下降幅度明显大于对照组(P<0.05);两组患者视觉功能恢复率均明显增加(P<0.05),且研究组恢复率明显大于对照组(P<0.05)。研究组并发症发生率明显低于对照组(P<0.05)。结论:双眼外直肌后徙术较单眼外直肌后徙联合内直肌缩短术有更好地临床效果,且安全性更高,值得临床推广。

Exploring Coverage of the 2008 Irish Dioxin Crisis in the Irish and UK Newsprint Media

The 2008 dioxin crisis occurred as a result of contamination of Irish pork. The event had significant implications for Ireland’s economy and the reputation of its agricultural industry, as well as raising concerns for human health. This study describes the results of a content analysis of Irish and UK newspaper coverage of the 2008 Irish dioxin crisis, as this is likely to provide insight into how public perceptions of this issue were shaped. Articles from 16 print publications were systematically sampled for the period December 2008 to February 2009. The resulting data set of 141 articles was examined using a coding protocol developed based on previous research and refined during piloting. Results indicated that the dioxin crisis was primarily portrayed by the media as an industry/economic crisis, dominant in 26.9% of articles in the sample. Within this dominant portrayal, the agricultural industry was frequently cited as being in crisis (42.6%); however, the implications of the crisis on the wider economic environment also received attention (17.7%). Differences between Irish and UK-based media were also examined, revealing that while the Irish media most frequently described the crisis in terms of its impact on the industry and economy, the UK media were more likely to portray the crisis as a risk to health. These dominant media messages and message framings have implications for the public understanding of the issue in each country and potential consequences regarding perception of the adequacy of existing food policy and regulatory oversight.     

行政诉讼的裁判基准研究——以契税客体内含的私法规则为中心

契税客体是契税行政法律关系变动的基础,法院审理契税行政诉讼案件的裁判基准源自对契税客体的判定。在税法理论上,契税客体有债权行为说和物权行为说两种观点,两种学说下的法律后果完全相反。法院审理契税案件的核心任务是维护契税立法的稳定性。通过对现行契税立法条文的目的解释和民法客体理论检视,可以发现立法对契税客体采债权行为说。面对契税立法缺漏,法院应当恪守"债权行为说",并援引私法规则形成契税行政诉讼的裁判基准。对于房屋预售引发的滞纳金争议,法院应居中将"合同签订日"扩张解释为"竣工验收备案日"做出裁判。对于合同解除引发的退税争议,法院应当依据交易是否已成立来确定税局应否退税。
