高频电磁场对工人行为功能的影响

采用世界卫生组织推荐的神经行为核心测试组合（ＷＨＯ－ＮＣＴＢ），对高频作业工人４１名（平均工龄１３．９ａ（年）及年龄、性别、文化程度与接触组相匹配的对照组工人３９名（平均工龄１３．３ａ）分别进行了行为功能测试。结果表明高频作业工人部分情感状态得分和某些行为功能得分与对照组相比差异有显著性。长期接触高频电磁场可能引起工人情感状态改变，记忆力减退、注意力分散及心理运动稳定度下降。     

地膜覆盖条件下红花生长发育规律及其与产量关系的研究

对地膜覆盖条件下红花生长发育规律及其与产量的关系进行了研究。结果表明,地膜红花与露地红花生长发育规律基本一致,但地膜红花生育进程明显提前,各个阶段的生长量明显增多,花的产量及籽粒产量极显著提高。     

新华社区部分高血压患者危险因素分析

目的 了解本社区高血压患者的危险因素现状，探讨干预对策。方法 采用分层整群抽样的方法，随机抽取社区4个里委2级、3级高血压患者402例作为研究对象，收集各项危险因素如性别、年龄、血脂、血糖、吸烟、饮食、体育锻炼、体重等，并进行统计分析。结果402例高血压患者1年内进行所有相关辅助检查者有14例，占3．48％；1年内进行相关辅助检查一项者306例，占76．12％。饮食控制及进行体育锻炼有300例，占74．43％；吸烟62例，占15．42％。结论 高血压患者对饮食控制及体育锻炼、吸烟有害的知晓率明显提高，而对相关辅助检查认识不足。     

Studies on the chemical constituents of the roots of Rhododendron molle G. don

Summary The compounds from the root ofRhododendron molle G. Don were isolated, purified by various chromatographic techniques, and their structures were identified according to the physical and chemical features and spectral data. Three compounds were separated from the root ofRhododendron molle G. Don and identified as Rhodojaponin-III,taraxerol, β-sitosterol for the first time.

SA、F/TPSA及PSAD在前列腺癌诊断中的作用

目的 :探讨血清前列腺特异抗原 (PSA) ,血清总PSA及游离PSA比值 (F/TPSA)及前列腺特异性抗原密度(PSAD)在前列腺癌诊断中的作用。方法 :对 5 1例前列腺癌患者及 14 5例良性前列腺增生症患者PSA、F/TPSA及PSAD值的差异进行分析、比较。结果 :前列腺癌组血清PSA及PSAD高于良性前列腺增生组 ;而F/TPSA值低于良性前列腺增生组 ,差异均有显著性。结论 :PSA >4ng·ml-1作为筛选前列腺癌的临界值存在一定缺陷 ;当PSA <10ng·ml-1,F/T值有助于鉴别前列腺癌和良性前列腺增生 ;而PSAD对于筛选前列腺活检病例亦有一定价值。     

Hyperfractionated radiation therapy combined with concomitant chemotherapy for inoperable stage III non-small cell lung cancer: clinical analysis of 70 cases]

OBJECTIVE: To evaluate the effect of hyperfractionated radiation therapy and concomitant chemotherapy for inoperable stage III non-small cell lung cancer (NSCLC). METHODS: Seventy patients were randomized equally into two group. The therapy group received radiotherapy with hyperfractionated radiation therapy combined with concomitant chemotherapy, and the control group was treated with chemotherapy only. RESULT: The overall response rate, including the rate of both complete (CR) and partial responses (PR), in the therapy group was 60.0% with a CR rate of 8.6%. The overall response rate in the control group was 40.0% with a CR rate of 5.7%. The difference in overall response rate was statistically significant between the two groups (P<0.05). The median survival time, 1- and 2-years survival rate were 12.8 months, 48.6%, and 25.7%, respectively, in the hyperfractionated radiotherapy group, and 9.4 months, 34.3%, and 17.1%, respectively, in the chemotherapeutic group (P 0.031). The major toxic effects of the chemotherapy were myelosuppression and radiation esophagitis. CONCLUSION: Hyperfractionated radiation therapy plus concomitant chemotherapy with paclitaxel for inoperable stage III NSCLC improves the short-term response of the patients, but fail to raise the survival rate.     

18F-FDG PET/CT对非小细胞肺癌区域淋巴结诊断的假阴性与假阳性研究

目的探讨18^F-FDG PET／CT在检测非小细胞肺癌（NSCLC）区域淋巴结中出现假阴性和假阳性的因素。方法随机选择手术治疗的NSCLC患者48例，术前1周内行18^F—FDG PET／CT检查，同期行CT增强扫描，术后根据病理检查结果分析PET／CT诊断NSCLC区域淋巴结转移的假阴性与假阳性因素。结果48例患者共切除区域淋巴结313枚，转移淋巴结51枚，PET／CT结果7枚假阴性。8枚假阳性，阳性预测值和阴性预测值分别为85％，97％，高于CT（57％，94％；P=0．002，0．045）。3枚假阴性淋巴结内的癌灶较小；2枚淋巴结短径约为0．4mm，小于PET／CT的空间分辨率；2枚紧邻原发灶的淋巴结，图像无法区分而视为原发灶。8枚假阳性淋巴结为患者在原发病灶基础上并发不同程度的肺部疾病和淋巴结炎症，使其糖代谢率增高。结论假阳性出于（1）淋巴结的短径小于PET／CT的空间分辨率；（2）淋巴结内的小癌灶糖代谢率较低；（3）紧邻原发灶的淋巴结与原发灶无法区分。原发肿瘤合并肺部疾病是导致PET／CT出现假阳性的重要原因。
