嘉兴外来人员生活环境与肠道传染病相关知信行现况调查分析

目的了解城郊结合部外来人员聚集地生活环境现况和霍乱等肠道传染病健康知信行情况,进一步明确肠道传染病防治健康教育与健康促进工作的重点开展方向。方法采用随机抽样的方法,运用统一设计的调查问卷对嘉兴市5县2区城郊结合部等外来人员聚集地进行流行病学调查。结果93.06%的调查对象以租房为主,90.61%的生活用水来源于自来水,9.25%用井水;78.61%的人知道霍乱传播途径,21.53%的人知道霍乱主要临床症状,28.03%的人知道肠道传染病全部预防措施;77.31%的知识来源于电视,其他顺位依次为书刊、广播、家人或朋友处;希望获得宣传资料形式:传单占46.68%,墙报占31.21%。结论外来人员租房人数居多,有部分人使用井水;肠道传染病相关知识了解的较少。应采取多部门齐抓共管来改善外来人员聚集地的生活环境,因地制宜地对外来人员开展有针对性的预防肠道传染病健康教育。

La maladie de Sinding-Larsen et Johansson

The Sinding-Larsen and Johansson disease is a non-negligible cause of gonalgia among children of 10 to 14, often misinterpreted as « growing pain . The disease is a benign pathology of the lower pole of the patella which occurs preferentially in physically active children. Our study, carried out in conjunction with the medical department INSEP, is based on a literature review as well as an analysis of 14 cases over two years. The present work eventually led to the differentiation of four etiopathological categories accounting for all the radiochemical evolutions observed. At the origin of these four categories, two factors coexist: the local fragility (the presence of cartilage at the lower pole of the patella) and the trigerring factor, which is most often sports practice. This explains why among children practicing sports, even intensively, only few suffer from this disease.It is essential to know the different radiological aspects of the normal patella in children, in order not to misinterpret one of these aspects with the Sinding-Larsen and Johansson disease.Always benign, the Sinding-Larsen and Johansson disease can very seriously disturb the « careerof children, engaged in high-level sports activity, the average time of evolution being seven months.     

吉林省七年鼠情监测结果分析

吉林省经七年来的鼠情监测,基本查清与人们接触密切的鼠类,特别是传播疾病的主要鼠类的分布规律,分析出我省家鼠有两个高峰(6月和10～11月),野鼠也有两个高峰(6月和10月),这与我省流行性出血热两个高峰相吻合,鼠峰在病峰之前。1986年以后,由于我省开展大规模灭家鼠活动,家鼠高峰已不存在规律性。通过几年来的灭鼠活动,使家鼠密度呈下降趋势,城镇褐家鼠和小家鼠构成比发生变化。城镇未爆发家鼠型流行性出血热。鼠情监测为灭鼠防病工作提供了科学依据。     

Use of the 90Sr applicator for intraoperative radiation therapy in a mouse tumor model

Intraoperative radiation therapy (IORT) research is limited by the lack of small-animal models. We have implanted B16 melanoma into mouse kidneys, which we subsequently operated upon and irradiated with beta rays from a ⁹⁰Sr ophthalmic applicator. The IORT has effectively prolonged survival and produced some cures. The strategy should be applicable to other murine tumors and to other internal implantation sites.     

荧光分光光度法测定水产品中烷烃类、芳烃类污染物

目的：对使用荧光分光光度法测定水产品中烷烃类、芳烃类污染物的方法进行验证,并检测三类样品。方法：通过氢氧化钠-乙醇皂化处理,用正已烷萃取,用石油醚溶解,测量萃取物荧光强度值进行定量。结果：测得标准油在0.00～12.0μg/ml范围内线性关系良好,相关系数0.9999,检出限为0.2 mg/kg,平均回收率90.2%,RSD5.4%。结论：本法准确度、灵敏度高,检出限低,操作稳定性好。     

心律失常运动员心输出量的研究

近年来由于训练强度不断增大,高水平运动员心律失常的发生率显著增加。本文研究资料表明,男心律失常组安静时心搏量明显大于正常组(P<0.05),而运动后心搏量降低(正常组心搏量增加),说明心律失常的运动员心脏储备能力差,心脏泵血功能降低,应予慎重对待。

Modulation of infection-induced inflammation and locomotive deficit and longevity in senescence-accelerated mice-prone (SAMP8) model by the oligomerized polyphenol Oligonol.

Oligonol is produced from the oligomerization of polyphenols (typically proanthocyanidin from a variety of fruits such as lychees, grapes, apples, persimmons, etc.) and contains catechin-type monomers and oligomers of proanthocyanidins. The ability of Oligonol to affect infection-dependent eye inflammation, locomotion and longevity in senescence-accelerated prone mice (SAMP8) (a model of senescence acceleration and geriatric disorders with increased oxidative stress and neuronal deficit) was investigated. Oligonol (60mg/kg) significantly modulated the extent of inflammation scores in the eye of SAMP8 mice. Examination of the mice indicated infection with mouse hepatitis virus and pinworm (Syphacia obvelata) in both males and females and with the intestinal protozoa (trichomonad) in males. A comparison of the two groups (using log-rank test) and the difference in the mean life span between groups (using Student's t-test) indicated significant differences in survival (p=0.043) and the mean life span (p=0.033) in male SAMP8 mice. Oligonol increased the mean life span and this was statistically significant. In the open-field locomotive test, the 7-week-old SAMP8 mice crossed more than 40 partitioned lines in 1min. At 48-week-old control untreated male SAMP8 crossed 2 lines. The Oligonol-treated 48-week-old male SAMP8 mice crossed 17 lines however. The improved locomotive activity was statistically significant even after 36weeks in the Oligonol-treated male SAMP8 but this was not the case throughout the time course of the study in the Oligonol-treated female SAMP8. Thus Oligonol treatment to SAMP8 mice modulated the severity of infection-dependent inflammation, prolonged life-span and significantly improved locomotive activity indicating potential benefit to aging-associated diseases such as Alzheimer's or Parkinson's diseases. This presents potential for further research to define infection-dependent inflammation associated with degenerative conditions and the molecular mechanism of dietary antioxidant protection.
