生活饮用水铊短期超标的风险评估探讨

目的 针对2017年突发饮用水铊污染事件，开展饮用水中铊短期暴露对人群健康的风险评估。方法 结合国家十二五重大专项课题“突发事件供水短期暴露风险与应急管控技术研究”科研成果，采用收集和分析相关数据、确定健康效应分离点、选择不确定系数和推导短期饮水水质安全浓度的健康风险评价模型开展短期暴露健康风险评估。结果 饮用水中铊短期暴露饮水水质安全浓度（SWSC）为0.007mg/L。2017年嘉陵江饮用水铊污染事件中铊最高浓度为0.00059mg/L，虽超过《生活饮用水卫生标准》（GB5749-2006）的限值要求，但处于短期暴露饮水水质安全浓度范围内。结论 本次污染事件铊的短期暴露健康风险处于可接受水平。     

Immediate Continence Rates in RALRP: A Comparison of Three Techniques

Methods:We retrospectively analyzed the patients who underwent RALRP for localized prostate cancer by a single surgeon in our clinic from January 1, 2009–February 1, 2016. Continence was defined as no leakage or use of a safety pad for minimal leakage. The main outcome measure was continence at postoperative week 1 and months 1, 6, and 12.Results:Between 2009 and 2016, 239 patients underwent RALRP for localized prostate disease. Seventy-four patients underwent a standard approach (group 1), 88 had posterior reconstruction (group 2), and 77 had posterior reconstruction with total anatomic restoration (group 3). After 1 week, 24.3% of the patients in group 1 (18/74), 31.8% in group 2 (28/88), and 45.8% in group 3 (33/72) were continent (P = .02). One month after the surgery, continence rates for groups 1, 2, and 3 were 56.7, 67, and 75%, respectively (0.065). After 6 and 12 months, continence rates for groups 1, 2, and 3 were 72.9 and 87.8%, 81.8 and 89.7%, and 84.7 and 91.6%, respectively (P = .178 and .7484).Conclusion:Anatomic restoration improves continence rates in the early period after RALRP. Even though other parameters were higher in the total restoration group, immediate continence (at 1 week) was significantly better.     

An unexpected complication of acute pancreatitis: Intra-cardiac thrombus

Left atrial thrombus after acute pancreatitis (AP) is a rare clinical statement. Because of induction of systemic prothrombotic process by AP; some patients with underlying risk factors may develop an intra-cardiac thrombus. We present a 53 years-old-woman with moderate mitral stenosis and atrial fibrillation. However the patient was under warfarin treatment, she developed a big left atrial big thrombus which was originated from left atrial appendage after she was suffered from AP.
