血清TPS浓度在消化道肿瘤中价值的研究

共选择３０例消化道肿瘤病人，其中食管癌，胃癌，大肠癌各１０例，设健康献血者３０例，对两组血清特异型组织多肽抗原浓度进行了检测，结果肿瘤组血清ＴＰＳ浓度明显高于健康人。消化道肿瘤阳性检出经达７０％，其中食管癌８０％，胃癌６０％，大肠癌７０％。消化道肿瘤合并淋巴转移阳性检出率达７６．９％，其中食管癌１００％，胃癌６６．７％，大肠癌７０．０％。随着病程发展，血清ＴＰＳ浓度呈现升高趋势。     

血康口服液与他莫昔芬联合治疗免疫性血小板减少性紫癜疗效观察

联合应用血康口服液和他莫昔芬治疗成人免疫性血小板减少性紫癜(ITP)20例。疗程超过2月。15例患者的血小板(BPC)计数明显上升,有效率为75％(15/20),对于激素治疗无效者,仍有良效。对月经过多者和不适合应用激素者尤为适应。两药合用无明显副作用。治疗起效时间较快,平均13天。疗效持续时间较长,长者已达一年以上。     

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。     

万艾可治疗ED时对BPH引起LUTS改善的研究

目的 :探索、研究万艾可在治疗阴茎勃起功能障碍 (ED)时对由良性前列腺增生 (BPH)引起的下尿路症状(LUTS)的影响。　方法 :32例ED同时伴有BPH的研究对象 ,采用IIEF 5问卷表和IPSS评分表 ,在服用万艾可前和服药后 6个月分别各填写一次 ,应用单因素方差分析对所得到的前后评分进行统计学分析。结果 :在服药前32例ED中 ,轻、中、重分别为 14、13、5例 ,BPH中轻、中、重分别为 3、15、14例 ;服药后IIEF 5评分平均上升4 2 .36 % ,IPSS评分平均下降 2 0 .14 % ,两者在统计学上都有显著性差异 ,P <0 .0 1。　结论 :在治疗中老年性ED合并BPH中 ,应用万艾可既能治疗ED ,取得完美的性生活 ,又能达到改善由BPH引起的LUTS。万艾可是一治疗ED有效的药物 ,但对于前列腺基质平滑肌亦有辅助性松弛作用 ,因此也有助于BPH时LUTS的缓解。     

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.
