简介：摘要：青浦区作为上海重要的生态环境管控区，为治理青浦区某农业园区农业面源污染问题，提升生态环境质量，结合园区实地调研情况，提出采用三级缓冲带与水循环相结合的综合治理方式，为农业园区面源污染提供参考。

简介：【摘要】目的 比较三维适形放射治疗(3DCRT),调强技术(IMRT)在食管癌的剂量学差异。方法 用2019年10月-2020年10月院内收治的62例食管癌患者，根据不同放疗方式均分两组，各31例。参照组用3DCRT，观察组用IMRT，靶区剂量学指数和不良反应。结果 实施后，参照组的两项对比数据比观察组略差，（P＜0.05）统计学意义明显。结论 两种操作在剂量学上，存在较大差异，IMRT的情况更理想，3DCRT略差，同时，因操作导致的不良反应极少。

简介：　　【摘 要】 目的：研究针对非小细胞肺癌（ NSCLC）脑转移患者实施全脑放疗联合靶向治疗和同步放、化疗治疗后的临床效果。方法：研究对象为本院收治的 66例非小细胞肺癌（ NSCLC）脑转移患者，将所有患者采用数字法随机分成两组，对常规组 33例患者实施同步放、化疗治疗，对治疗组 33例患者实施全脑放疗联合靶向治疗，观察比较两组非小细胞肺癌（ NSCLC）脑转移患者的临床疗效。结果：治疗组患者的脑评估转移率和总体评估值均显著优于常规组患者，组间差异有统计学意义（ P<0.05） ;治疗组患者的不良反应发生率（ 15.15%）显著低于常规组（ 36.36%），组间差异具有统计学意义（ P<0.05）。结论：相较于同步放、化疗，全脑放疗联合靶向治疗可以有效治疗非小细胞肺癌（ NSCLC）脑转移患者，同时也可以有效控制病情的发展和不良反应的发生。  　　【关键词】 非小细胞肺癌（ NSCLC）脑转移 ;全脑放疗 ;靶向治疗 ;同步放、化疗 ;不良反应 ;治疗效果 ;病情控制  　 [Abstract] Objective: To study the clinical effect of whole brain radiotherapy combined with targeted therapy, concurrent radiotherapy and chemotherapy for patients with brain metastases from non-small cell lung cancer (NSCLC). Methods: 66 patients with brain metastases from non-small cell lung cancer (NSCLC) in our hospital were randomly divided into two groups, 33 patients in the conventional group were treated with concurrent radiotherapy and chemotherapy, and 33 patients in the treatment group were treated with whole brain radiotherapy combined with targeted therapy. Results: the brain evaluation metastasis rate and overall evaluation value of the treatment group were significantly better than those of the conventional group, the difference was statistically significant (P < 0.05); the incidence of adverse reactions in the treatment group (15.15%) was significantly lower than that in the conventional group (36.36%), and the difference between the two groups was statistically significant (P < 0.05). Conclusion: compared with concurrent radiotherapy and chemotherapy, whole brain radiotherapy combined with targeted therapy can effectively treat patients with brain metastasis of non-small cell lung cancer (NSCLC), and can effectively control the development of the disease and the occurrence of adverse reactions.
