目的:进一步探讨B超对稽留流产的超声诊断及其临床意义.方法:对25例稽留流产病人于充盈膀胱后检查子宫、附件.结果:25例病人子宫均比孕周小,宫内回声归纳为三种类型:①空囊型(本组 10例);②类似水泡状胎块型(本组8例);③杂乱回声型(本组7例).结论:对稽留流产的病人B超不仅可排除异位妊娠及葡萄胎,并可早期了解胎死宫内的情况,避免了盲目性的保胎或人工流产,具有重要的临床意义. 相似文献

目的 了解T淋巴细胞异常在骨髓增生异常综合征(MDS)克隆造血中的作用.方法 对76例MDS患者的染色体核型、T淋巴细胞亚群及激活状态进行分析.结果 正常核型36例,异常核型40例,异常发生率52.6%.40例异常核型中,三体8(+8)24例,占异常核型的60.0%.与健康对照组比较,MDS患者CD+3 CD-19、CD+3 CD-4 CD+8以及CD+3 HLA-DR+细胞百分率显著升高,CD-3(CD16 CD56)+细胞的百分率明显降低.将MDS患者进行核型分组,异常核型组CD+3(CD16 CD56)+细胞的百分率显著高于正常对照组.将+8核型从MDS异常核型中独立出来进行分析,CD+3 CD+4 CD-8细胞的百分率明显低于正常核型以及其他异常组,CD4/CD8的比值明显低于健康对照组.结论 MDS存在T淋巴细胞异常,异常核型MDS可能恶性克隆增殖更为优势,预后更差.+8核型MDS存在更为严重的免疫监视功能下降,导致恶性克隆过度增殖与残存造血过度受抑. 相似文献

目的 分析t(8;21)急性髓系白血病(AML)患者的细胞形态学、免疫表型、遗传学、分子生物学(MICM)分型及临床治疗疗效.方法 运用瑞特染色法、FAB细胞形态分类标准、流式细胞术(FCM)直接免疫荧光标记技术、遗传学染色体吉姆萨显带技术及RT-PCR技术对70例确认有t(8;21)与AML1-ETO融合基因双阳性的AML患者及70例正常染色体核型的AML患者进行分析和比较.结果 70例t(8;21)AML患者中M11例,M2 64例,M4 3例,无法分型的急性白血病(AL)2例;免疫表型分析发现CD13、CD33、CD34、CD117高表达,40%表达CD19,11%表达CD15,10%表达CD11b,7%表达CD7;遗传学显示50%的t(8;21)AML患者有附加染色体异常,主要为性染色体丢失、9q-及超二倍体;RT-PCR检测AML1-ETO融合基因100%阳性.CD+19t(8;21)AML患者完全缓解(CR)率72%,CD+19伴CD+7t(8;21)AML患者CR率为0,正常核型CR率31%.结论 t(8;21)AML患者主要在M2中集中出现,附加染色体异常较多见.CD19表达较高,而CD7表达极低,CD34、CD117高表达,这些抗原的表达可能与核型密切相关.CD+19是预后良好的指标,但同时出现CD+7,则预后不良. 相似文献

在骨科门诊和病房中,发现有不少带状疱疹病人极易误诊,因为该病早期均因颈肩腰腿痛剧烈而来就诊,往往首先疑诊颈椎病(神经根型)、腰椎间盘突出症、肋间神经痛而进行门诊或住院治疗.但数天或数周后发现有集簇状水泡,经过皮肤科医生会诊后确诊为带状疱疹.现将误诊的15例带状疱疹早期病例临床小结如下. 相似文献

目的 探讨我国成年伴NPM1基因突变的急性髓系白血病患者(NPMc+AML)的临床特点,初步探讨定期定性检测该突变在早期判断AML复发中的意义.方法 采用聚合酶链反应(PCR)-毛细管电泳法对95例成年初治AML患者检测NPM1突变情况,并选取其中5例完全缓解患者定期检测该突变.结果 95例成年AML患者NPM1突变发生率为29.5%(28/95);≥40岁患者突变发生率[40.0%(22/55)]明显高于<40岁患者[15.0%(6/40)](λ 2=6.963,P=0.012);正常核型AML患者突变发生率[51.1%(24/47)]明显高于异常核型患者[8.3%(4/48)](λ2=20.860,P=0.000).AML患者发生NPM1突变以M5[72.7%(16/22)]、M2[36.3%(8/22)]常见,在具有重现性染色体异常的AML中,未发现该突变.NPMc+AML患者白细胞、血小板计数及乳酸脱氢酶水平均明显高于NPMc-AML组(t值分别为4.132、4.603、4.069,均P<0.05).NPMc+AML患者完全缓解率、无复发生存率及总生存率均明显高于NPMc-AML患者(λ2值分别为10.448、4.146、4.384,均P<0.05).定期检测的患者血液学复发前1.5~2.0个月草新出现NPM1基因突变.结论 NPM1基因突变在成年AML患者中,尤其是正常核型AML患者中有较高的发生率,临床表现为患者年龄偏大,白细胞计数、血小板计数、乳酸脱氢酶均较高,NPM1基因突变是成年AML患者预后良好的指标.定期定性监测该突变可早期判断AML复发. 相似文献

Cancer of the cardia is traditionally discussed with cardiac cancer of the lower portion of the esophagus and upper gastric cancer invading the esophagus, and the specific characteristics of cancer of the cardia have never been clearly defined. We reviewed the outcome of 172 patients with adenocarcinoma of the cardia who had undergone radical surgery between 1949 and 1994 in the Division of Gastrointestinal Surgery of the Cancer Institute Hospital. The centers of the tumors were located within 2 cm above and below the boundary between the esophagus and the stomach, and their longitudinal diameter was less than 8 cm. We divided the patients into an early period (1949-1979; n = 79) and a late period (1980-1994; n = 93), and focused on the historical transition. There were no differences in patient gender or histology between the two periods. However, the late period was associated with fewer cases of esophageal invasion and shorter longitudinal diameter, as the age of the population advanced. The number of advanced cancers such as the localized and infiltrative type had decreased, and early cancer and early clinical stage had become more common, but despite the fact that the number of early cancers had increased, extended dissection, such as thoracic and paraaortic lymph node dissection, was performed more frequently. By clinical stage, the long-term outcome markedly improved in Stage I patient in the late period, and tended to improve in Stage II and III patients. This appears to have been attributable to the prevention of micrometastasis by extended dissection, although the number of early cancers is another major potential cause. There were no differences in the outcome of Stage IV patients between the two periods, and further advances in multimodality therapy must be awaited. The range of resection is basically proximal gastrectomy, and if there are adequate indications, the prognosis is favorable. In view of the status of lymphatic flow and lymph node metastasis, and long-term results, lateroaortic lymph node dissection is important. Since the number of early cancer patients has been increasing, if intraabdominal recurrence is prevented, intrathoracic lymph node dissection will contribute greatly to the outcome of such patients. 相似文献

Some theories of personality hold that an individual's perception of others is influenced by his own personality characteristics; more specifically, that a trait of low social value will be projected more into others, and that insight into the possession of these characteristics reduces this distortion. These 2 hypotheses were tested by having a group of college students rate each other (including themselves) on degree of friendliness or hostility. Agreement with group rating about self yielded the insight score. In general, the hypotheses were supported; the "friendly" Ss were most accurate in their perception of others, and insight was positively associated with accurate perception.

The effect of 20 different antibiotics on chemotaxis by human neutrophils was studied. Human leukocytes incubated with chloramphenicol, rifampin, sodium fusidate, and tetracyclines in vitro showed markedly depressed migration. The mechanisms by which these antibiotics affect leukotaxis are discussed. 相似文献

Usage of quality of life of psychiatric patients' relatives as the parameter of estimation of the quality of psychiatric care is considered. By means of standard questionnaire elaborated by the authors as well as by means of both individual and group conversations the quality of life was analyzed in 40 relatives which lived together with psychiatric patients. Different spheres of their life and difficulties (financial, social-psychologic, production) were examined in families with such patients. The defects of psychiatric care that had direct influence on the quality of life of the psychiatric patients' relatives are outlined. 相似文献
