放射治疗71例骨转移癌止痛效果分析

目的观察低于常规剂量的2种分割方式治疗骨转移性疼痛的疗效。方法71例恶性肿瘤晚期骨转移患者,总计93处骨转移灶,根据疼痛程度及行动受限程度,采取2种均低于常规剂量的分割方式进行放射治疗,分别为Dm30Gy/10f/2W,Dm30Gy/6f/2W。观察疼痛缓解情况。结果2种分割方式止痛有效率分别为88%、95%。两组间无显著差异性(P>0.05)。与国内多数文献报告的结果接近。结论低于常规剂量的分割方式对转移性骨痛疗效与常规剂量的分割方式的疗效相当,且简便易行。     

Effect of Kang''''ai Injection(康艾注射液) on Serum Level of Soluble Interleukin-2 Receptor and Vascular Endothelial Growth Factor in Patients with Esophageal Carcinoma during Radiotherapy

Radiotherapy(RT)is an important ap-proach for treatment of esophageal carcinoma(EC),especially for patients who have missedthe chance of surgical section.The efficacy ofRTis not satisfactory for its1-year,3-year and5-year survival rates being merely50%,20%,and10%respectively(1).Researches in recent years showed thatbetter efficacy can be obtained by combiningRTwith Chinese herbal medicines for EC thatincapable to be resected.Kang ai Injection(康艾注射液,KAI)is a Chinese herbal prep-arati…     

经直肠超声引导下经会阴125I粒子永久植入治疗前列腺癌的初步经验

目的探讨经直肠超声引导下经会阴125I粒子永久植入治疗前列腺癌的疗效和并发症。方法本组前列腺癌患者5例。年龄61￣83岁,平均70.4岁。临床分期T2bN0M0者2例,T3aN0M0者3例。Gleason评分6分者2例,7分者1例,8分者2例。术前前列腺特异性抗原(PSA)4.5￣17.5ng/ml。T3a期患者植入治疗前先行内分泌治疗。术前制定治疗计划,经直肠超声引导下经会阴125I粒子永久植入操作。术后观察PSA水平变化,连续3次PSA升高即为生化复发,观察术后尿路和直肠并发症发生情况。结果5例患者均术后恢复顺利。术后随访18个月,PSA均明显下降,PSA为0.1ng/ml者3例,0.01ng/ml者1例,0.04ng/m1者1例。5例患者术后均出现不同程度的尿路刺激症状,但6个月后逐渐好转。4例术后出现排便次数增多,术后3个月均好转。未发现尿失禁、直肠溃疡等并发症。结论经直肠超声引导下经会阴125I粒子永久植入治疗前列腺癌的疗效确切,创伤较小。     

Acute subcortical stroke and early serotonergic modification: a IDAP study

The intensity dependence of the auditory-evoked potentials (IDAP) is inversely related to serotonergic tone. Depression is frequently observed after stroke, associated with cognitive impairment and increased mortality. Aim of this study was to investigate the serotonergic tone in acute stroke patients by IDAP. Consecutive patients with an acute stroke admitted in our stroke unit were evaluated using clinical and instrumental examinations and compared with healthy controls. The IDAP was calculated as the linear amplitude/stimulus intensity function (ASF) slope, by measuring the peak-to-peak amplitude of Nl-P2 on four blocks of different stimulus intensities. Twenty patients were enrolled; 11 had a right brain infarction; nine had depressive symptoms (DS). The ASF slope of the auditory-evoked potentials was markedly increased in stroke patients compared with controls ( P  = 0.021). Stroke patients with DS had a significant steeper ASF slope than controls ( P  = 0.017). There was no statistical difference in ASF slope between stroke patients without DS and controls. Post-stroke depression pathophysiology is still debated. Our study suggests that in acute stroke patients with DS, there is a direct involvement of the serotonergic system, regardless the degree of disability and the site of the lesion.     

The Post Therapy Breast

Both systemic and local therapy, for conditions of the breast and unrelated to it, may produce manuno-graphic changes. Some of these are characteristic, such as the pattern of scarring seen in reduction mammo-plasty. In many other instances, however, the changes produced overlap features commonly seen in malignancy. A knowledge of the timing, natural history and spectrum of these changes will aid mammographic interpretation.
