Discourses on the Toxic Effects of Internal Chemical Contamination in Catalonia,Spain

Human exposure to and contamination by environmental toxic compounds generates discourses and practices that merit greater attention. In this article, we assess internal chemical contamination and the risk of toxic effects as an experience related to the production of meaning in everyday life. Drawing on the analysis of semantic networks of narratives from semi-structured interviews conducted with 43 informants in Catalonia, Spain, we consider participants’ perceptions of the health risks of toxic compounds, including social discourses on exposure, toxicity, and internal chemical contamination, and on responsibilities, consequences, and proposed strategies for controlling toxic compounds. Informants’ narratives on the relationships between nature and nurture suggest that they no longer perceive rigid boundaries separating the human body from the external environment and its chemical pollutants.     

The worldwide coronavirus disease 2019 outbreak: Advice and recommendation on radiology management and infection control from makeshift hospitals in Wuhan

To describe and advise on management protocols and infection-protection experience of the radiology department in makeshift hospitals in Wuhan during the coronavirus disease 2019 (COVID-19) outbreak.Based on the literature review and the experience in the frontline, we retrospectively reviewed the configuration of the radiology department, human resource, personal protection, examination procedures for patients confirmed with COVID-19 in Wuhan fangcang shelter hospital.From February 11, 2020 to March 10, 2020, 2730 and 510 CT examinations were performed in the Hanjiang shelter hospital and Hanyang Sports School shelter hospital, respectively, including initial examinations and re-examinations. The maximum number of daily CT examinations reached 289. The CT scanned a patient approximately once every 13 mins.Fangcang shelter radiology department could be powerful components of both global and national responses to the COVID-19 pandemic.     

质子放疗前后恶性肿瘤患者T细胞亚群的变化

目的探讨用质子放射治疗恶性肿瘤病人的过程中,通过检测病人T细胞亚群的变化,来判断质子治疗是否对细胞免疫功能产生影响。方法将20例经病理学证实的恶性肿瘤患者采用质子束局部外照射,在治疗前后分别取病人外周血,用流式细胞仪检测放疗前后T细胞亚群水平。结果CD4+T细胞、CD8+T细胞无明显变化,CD4+T/CD8+T在治疗后比治疗前明显降低(P<0.05)。结论质子治疗时可导致T细胞亚群变化,抑制细胞免疫功能。     

微量泵通过鼻饲管持续均匀泵奶在早产儿喂养中的应用

目的:探讨微量泵通过鼻饲管持续均匀泵奶用于早产儿喂养的效果.方法:将58例早产儿随机分为甲、乙两组.甲组30例采用微量泵泵奶法,以微量泵通过鼻饲管持续均匀泵奶,2～3ml/h;乙组28例则采用常规间歇鼻饲喂奶法,以注射器通过鼻饲管每2h注奶4～6ml.两组均观察3～5d,比较观察期间两组患儿平均每人每天进奶量、吐奶及残奶情况,同时比较两组患儿胃管平均留置时间及出生2周后平均增加体重.结果:甲组患儿平均每人每天进奶量高于乙组,吐奶、残奶出现例数少于乙组,进胃管平均留置时间少于乙组,而出生2周后平均增加体重高于乙组,两组比较均有显著性差异(P<0.05).结论:对早产儿给予微量泵通过鼻饲管持续均匀泵奶,可提高进奶量,减少吐奶、残奶例数与胃管平均留置时间,增加早产儿体重,值得,临床推广应用.
