高能聚焦超声刀联合氟脲嘧啶、四氢叶酸治疗晚期胰腺癌临床疗效观察

目的探讨高能聚焦超声刀加氟脲嘧啶、四氢叶酸治疗晚期胰腺癌临床疗效及毒副作用。方法30例经病理学或细胞学确诊的晚期胰腺癌病人先用高能聚焦超声刀(HIFU)治疗，再予氟脲嘧啶、四氢叶酸联合化疗。氟脲嘧啶500mg／m^2加入5％GNS500ml静滴持续6小时以每天1次连用5天，CF(四氢叶酸)100mg／m^2加入生理盐水250ml静滴每天1次连用5天，28天为1周期，至少治疗2个周期。结果CR1例；PR9例；MR9例；NC5例；PD6例。总有效率63％。毒副作用主要消化道反应，其他副作用轻微。结论应用HIFU局部治疗胰腺癌同时合用四氢叶酸加氟脲嘧啶全身化疗近期疗效提高明显，止痛明显达75％，副反应小，值得应用。     

Osteoporosis and Back Pain among the Elderly

Questionnaire responses from 120 men and 337 women over the age of 50 years were studied to determine the prevalence of back pain among the elderly. In order to gain a rough indication of the back pain among elderly women which might be due to osteoporosis, the prevalence was compared in the two sexes. The prevalence of back pain without radiation to the legs and concomitant morbidity was found to be similar among men and women up to the 70–79-year age-group. After this age the prevalence was higher in women. Those with exceptional loss of body height or kyphosis had a high prevalence of back pain, while those who had sustained previous hip or radius fractures did not. There was increasing prevalence of back pain among women with increasing number of previous fractures. The study gives little indication of serious morbidity of osteoporosis in the form of back pain before very old age.     

正常足月孕妇骨矿物质含量的测定

用单光子吸收法对足月孕妇尺、桡骨骨矿物质含量（ＢＭＣ）、骨面密度（ＢＭＣ／ＢＷ）进行测定及作血清钙、磷的生化测定。结果显示：足月孕妇的尺、桡骨骨矿物质含量、骨面密度明显低于同年龄组的未孕妇女。主要因为妊娠胎儿的骨胳生长发育，需要孕妇向胎儿输送大量的钙离子，若母亲对钙摄入不足或吸收不良，则造成孕妇的骨矿物质含量降低，骨质疏松；而孕妇血清钙、磷降低不明显。     

桡骨与尺骨的测量及回归分析

本文测量了桡骨与尺骨各100例,其中桡骨15项指标,尺骨14项指标。并用IBM·PC—XT计算机DBASEⅢ数据库管理系统进行了统计分析以及用桡、尺骨最大长分别与桡、尺骨其它各项指标间进行直线相关分析,建立了25个回归方程。     

Inter- and intraobserver variability in the histopathological diagnosis of medullary carcinoma of the breast,and its prognostic implications

Summary One hundred thirty-one breast carcinomas with medullary features, registered in the Danish Breast Cancer Cooperative Group from 1977–1982, have been histopathologically reviewed by two senior pathologists and classified as typical medullary carcinoma (TMC), atypical medullary carcinoma (AMC), and non-medullary carcinoma (NMC). Diagnostic criteria were based on those put forward by Ridolfiet al. and Fisheret al. The procedure was repeated with an interval of about one year by both pathologists. The diagnostic interobserver agreement was 72% with a Kappa of 0.55. The intraobserver agreement was 77% and 63% with Kappa values of 0.64 and 0.44, respectively. To see whether the observed inter- and intraobserver variability had any prognostic implications, diagnostic subgroups for both pathologists were analyzed with Kaplan Meier plots for recurrence-free survival (RFS) and with log rank tests. In the first evaluation pathologist 1 segregated a group of TMC with a significantly better RFS than for the NMC group, and pathologist 2 segregated a group of TMC with a corresponding strong trend. These findings could not, however, be reproduced in the second evaluation. The study indicates that the criteria of TMC and AMC as proposed by Ridolfiet al. need to be sharpened and simplified in order to reduce inter-and intraobserver variability. Larger studies with a control group of infiltrating ductal carcinomas are mandatory to elucidate the clinical importance of the diagnoses of Typical and Atypical Medullary Carcinoma of the breast.

延髓—脊髓P物质能神经元下行通路参与毒扁豆碱的中枢升压反应

大鼠延髓腹侧面头端应用毒扁豆碱引起血压升高和心率加快,伴有延髓腹侧面头端胆碱酯酶活性降低和脊髓蛛网膜下腔灌流液中P物质样免疫反应活性升高。在延髓腹侧面头端应用阿托品或脊髓蛛网膜下腔注射P物质拮抗剂D-脯~2,D-苯丙~7,D-色~9-P物质均可阻断毒扁豆碱的心血管效应。脊髓蛛网膜下腔注射P物质抗血清或辣椒素均可减弱毒扁豆碱的升压反应。实验结果提示,毒扁豆碱作用于延髓腹侧面头端的M受体,兴奋了延髓-脊髓P物质能神经元下行通路,使之释放P物质,引起交感肾上腺髓质系统兴奋,从而使血压升高和心率加快。
