Partial mastectomy with axillary lymph node dissection and radiotherapy as a new treatment modality of breast cancer (I).

This is the first preliminary report among two consecutive papers. Partial mastectomy(PM), axillary lymph node dissection(AD) and radiotherapy (RT) were performed on seventeen operable breast cancer patients who had been admitted from April 1991 to March 1992 to the department of surgery, Yongdong Severance Hospital for improved cosmetic appearance and better survival rate. Of seventeen patients, 47% were T1 lesion and 76% were stage I and II. Extensive intraductal component(EIC) within or around the tumor was also analyzed. Twenty nine per cent of the patients were EIC positive. The mean number of axillary lymph nodes was 21.5 after PM with AD and 20.5 after mastectomy. For radiotherapy, 4,500 rad was delivered to the breast parenchyma and 1,600 rad of boost to the primary tumor site using the electron beam method after surgery. All patients have since been living well without any local recurrence and were satisfied with breast preservation for the one-year follow-up period. We concluded that the PM, AD and RT can be another surgical treatment modality of breast cancer. A longer follow-up data will be followed on the second paper.

脊椎滑脱症合并腰椎间盘突出的治疗

1987年6月至1995年1月我院共治疗脊椎滑脱55例,其中17例合并腰椎间盘突出,占31％,临床表现为顽固的腰骶痛和下肢根性放射痛。手术复位、融合不稳定脊椎的同时,均摘除突出的椎间盘髓核组织。经半年以上随访,疗效满意,作者分析了本病的病因病理,认为诊断该病必须综合性检查分析,脊髓造影或CT检查有一定影像学诊断价值,治疗宜早行探查手术。

Cystic spinal dysraphism of the cervical and upper thoracic region

Background Cystic dysraphic lesions of the cervical and upper thoracic region are rare and only a few series have been published about the topic. These malformations can be divided into categories that include both myelocystoceles and the so-called cervical meningoceles or myelomeningoceles.Methods A retrospective study of 18 patients was conducted.Results In 17 patients a squamous or a cicatricial epithelium of variable thickness covered the dome of the lesions, while the base was covered with full-thickness skin. In one case the skin was entirely normal. Four patients displayed associated CNS malformations and three more had systemic congenital anomalies. All patients underwent surgical exploration and the length of time between birth and surgery ranged from 6 h to 9 months. The most frequent surgical finding, seen in 14 patients, was a stalk connecting the dorsal surface of the spinal cord to the cyst. In three patients the findings were consistent with myelocystocele. Only in one case was a true meningocele found. Hydrocephalus and Chiari II malformation were not as consistently associated as in myelomeningoceles. Neurological signs and symptoms were not so marked as in myelomeningoceles and were found in the follow-up of four patients. In two of them there was a non-progressive deficit, probably expressing an imperceptible involvement of the nervous system in the first year of life. The histopathological findings were of three types: neuroglial stalks, fibrovascular stalks and myelocystoceles.Conclusions Cystic dysraphisms of the cervical and upper thoracic region differ clinically and structurally from meningomyelocele and have a more favorable outcome. We believe that these malformations have not been properly labeled and propose a classification based on the structures found inside the cyst.

低脉压与晚期慢性心衰患者利钠肽和死亡率升高独立相关

目的:脉压(PP)升高一贯用来预测有心血管疾病危险患者和轻度慢性心衰(CH F)患者的心血管疾病发生率和死亡率增高。相反,PP降低与急性失代偿性心衰患者死亡率升高相关。然而,尚不清楚PP对于晚期CH F患者的预测价值。方法和结果:采用Cox比例风险回归分析研究了1901例N YH A III或IV级CH F患者(平均年龄65岁,平均射血分数26%)的资料,经校正其他危险因素后,分析PP对死亡率的影响。检测了1个亚组患者的利钠肽水平。多元Cox回归分析表明,PP降低与死亡率增高相关(每增加10m m H g的H R为0.91,95%CI0.93～0.99),这一相关性独立于平均…     

卡维地洛对慢性心衰患者心室内和心室间同步性的影响

对30例稳定性心衰患者进行放射性核素心室造影和时相分析,确定基线时和最大耐受剂量卡维地洛治疗6个月后左心室和心室间的收缩同步性。与正常人群相比,心衰患者具有明显的心室不同步。基线时具有最显著不同步的患者中第50位百分位数表明,接受卡维地洛治疗后心室同步性得到显著改善,这与舒张末期左心室容量降低呈正相关。卡维地洛对慢性心衰患者心室内和心室间同步性的影响@Castro P.

Pretreatment with recombined human erythropoietin attenuates ischemia–reperfusion-induced lung injury in rats

Objective: Based on the findings that erythropoietin (EPO) has been proved to be a multiple functional cytokine to attenuate ischemia–reperfusion (I/R) injury in various organs such as brain, heart, and kidney in animals, this experiment was designed to evaluate the effect of pretreatment with recombined human erythropoietin (rhEPO) on I/R-induced lung injury. Methods: Left lungs of rats underwent 90 min of ischemia and then were reperfused for up to 2 h. Animals were randomly divided into three experimental groups as sham group, I/R group, and rhEPO + I/R group (a single dose of rhEPO was injected intraperitoneally 3000 U/kg 24 h prior to operation). Lung injury was evaluated according to semi-quantitive analysis of microscopic changes, tissue polymorphonuclear neutrophils (PMNs) accumulation (myeloperoxidase (MPO) activity), and pulmonary microvascular permeability (Evan's blue dying method). Peripheral arterial and venous blood samples were obtained for blood–gas analysis after 5 min occlusion of right lung hilus at the end of reperfusion. The serum concentration of tumor necrosis factor (TNF)- was also measured by the method of enzyme-linked immunosorbent assay. Results: Histological injury scoring revealed significantly lessened lung alveolus edema and neutrophils infiltration in the rhEPO pretreated group compared with I/R group (p < 0.05). The rhEPO pretreated animals exhibited markedly decreased lung microvascular permeability (p < 0.05) and myeloperoxidase activity (p < 0.05). Blood–gas analysis demonstrated that the pretreated animals had significantly ameliorated pulmonary oxygenation function (p < 0.05). The serum concentration of tumor necrosis factor- in rhEPO pretreated group was markedly decreased compared with that of I/R group (p < 0.05). Conclusions: Pretreatment with rhEPO appears to attenuate I/R-induced lung injury. This function is partly related with the capacity that rhEPO inhibits the accumulation of polymorphonuclear neutrophils in lung tissue and decreases the systematic expression of tumor necrosis factor-.
