目的 探讨胃黏膜相关淋巴组织(MALT)淋巴瘤患者的临床特点和预后.方法 回顾性分析我院2001年4月至2011年8月收治的103例胃MALT淋巴瘤患者资料,分析其临床特征和相关预后因素.结果 患者多起病隐袭,无特异性临床表现,以腹痛、腹部不适、体重减轻、纳差、恶心、呕吐等症状为主.Musshoff分期:Ⅰ/Ⅱ期75例(72.8%),Ⅲ/Ⅳ期28例(27.2%).非手术治疗组和手术治疗组患者的5年总生存(OS)率分别为78.9%和60.4%,两者差异无统计学意义(P =0.072);非手术治疗组的5年无进展生存(PFS)率为52.8%,显著高于手术治疗组(31.7%),两者差异有统计学意义(P=0.023).幽门螺杆菌(Hp)感染率91.2%,抗Hp治疗临床有效率达100%.在有完整随访资料的94例患者中,5年OS率为75%,5年PFS率为46%.预后相关分析提示:B症状、淋巴结转移、Musshoff分期、乳酸脱氢酶、β2-微球蛋白及国际预后指数评分是影响患者OS和PFS的相关因素,而Musshoff-ⅢE/ⅣE期、IPI评分>2分、B症状是影响患者OS的独立不良因素(P<0.05),Musshoff-ⅢE/ⅣE期是影响患者PFS的独立不良因素(P =0.027).结论 胃MALT淋巴瘤生存率高,预后良好;建议予以抗Hp治疗为主的非手术治疗,避免手术有创治疗.Musshoff-ⅢE/ⅣE期、B症状或IPI评分>2分是胃MALT淋巴瘤患者的不良预后因素.  相似文献

目的:探讨黏膜相关淋巴组织(MALT)国际预后指数(IPI)在中国人群MALT淋巴瘤患者中的适用性,并比较不同风险分层方法对MALT淋巴瘤的预后评估价值。方法:回顾2007年1月至2016年12月129例MALT淋巴瘤患者的临床资料,采用Kaplan-Meier法和log-rank法计算并比较MALT-IPI与IPI不同分层分组患者的总体生存率(OS)和无进展生存率(PFS)。结果:129例患者中位发病年龄56岁(22~82岁),其中胃MALT淋巴瘤53例(41.1%),肺MALT淋巴瘤33例(25.6%);Ann ArborⅠ~Ⅱ期71例(55.1%),Ⅲ~Ⅳ期58例(44.9%)。中位随访时间26个月(1~378个月)。总体5年PFS为69.41%,5年OS为90.23%。IPI评分低危、中低危和中高危/高危组患者5年OS、PFS差异无统计学意义;MALT-IPI评分低危、中危和高危组患者5年OS、PFS率逐渐降低,差异有统计学意义(P0.05)。结论:MALT-IPI评分适用于中国人群;相较于IPI评分,MALT-IPI评分对MALT淋巴瘤患者预后具有更好的评估价值。  相似文献

Many investigators have stated that the difficulties of imaging with acoustical energy through the skull result from the marked attenuation of the energy by the skull. In the literature measurements of total attenuation have been confused with those for absorption.Measurements made by us show that absorption by compact bone varies between 2–3 dB cm?1 MHz?1 and, in the low megaHertz region appears to be directly proportional to frequency.It has also between shown that the convoluted inner surface of the ivory bone of the inner table of the skull may degrade the collimation and directionality of the beam by refraction.Cancellous bone, such as is present in the dipole of the skull, greatly attenuates the energy. It is postulated that this largely results from scattering. It is also postulated that the energy propagates through cancellous bone as two components, one in the soft tissues and the other partly in the bony spicules. Observations suggest that attenuation due to scattering much more markedly affects the latter of these components and scatters more greatly the higher frequencies in a pulse of broad bandwidth.The energy in each component has varying propagation paths so that the later cycles in the pulse of each component are subject to increasing interference as a result of the variations in propagation times. The two components moreover may have different propagation times so that interference may occur between the pulses of each component as well.All of these phenomena degrade the collimation, coherence, directionality, beam width, pulse length, frequency and other properties of the ultrasonic energy upon which imaging through the skull depends.The interference effects described above are least for the first cycle in the pulse which usually is not the cycle of highest amplitude. Since, in the free field, most of the energy is concentrated around the beam axis, most of the energy in the field which is deflected from its normal propagation path is deflected away from the beam axis. Thus the directionality of the beam is least degraded in the beam axis. The effects of the skull in degrading the properties of the ultrasonic pulse would therefore be lessened if the amplitude of the first cycle of the pulse and the directionality of its energy could be used for imaging.  相似文献

SUMMARY: Organ transplantation has developed over the past 50 years to reach the sophisticated and integrated clinical service of today through several advances in science. One of the most important of these has been the ability to apply organ preservation protocols to deliver donor organs of high quality, via a network of organ exchange to match the most suitable recipient patient to the best available organ, capable of rapid resumption of life-sustaining function in the recipient patient. This has only been possible by amassing a good understanding of the potential effects of hypoxic injury on donated organs, and how to prevent these by applying organ preservation. This review sets out the history of organ preservation, how applications of hypothermia have become central to the process, and what the current status is for the range of solid organs commonly transplanted. The science of organ preservation is constantly being updated with new knowledge and ideas, and the review also discusses what innovations are coming close to clinical reality to meet the growing demands for high quality organs in transplantation over the next few years.  相似文献

This narrative review article was conducted to lay out a summarized but exhaustive review of current literature over mucocutaneous manifestations in 4 dimensions of SARS‐CoV‐2 pandemic: virus itself, treatment‐related, vaccine‐induced, and alteration of chronic dermatologic diseases following infection. Virus and vaccine‐related were mainly self‐limited and non‐severe. Treatment‐related reactions could be life‐threatening.  相似文献

Burkitt's lymphoma(BL) is an aggressive form of nonHodgkin's B-cell lymphoma with three variants namely endemic, sporadic, and immunodeficiency-associated types. It is endemic in Africa and sporadic in other parts of the world. While the endemic form is widely reported to occur in early childhood and commonly involves the jaw bones, the sporadic form typically presents as an abdominal mass. This presentation reports a rare case of sporadic form of BL clinically manifesting as a generalized gingival enlargement in an immunocompetent adult male which demonstrated an aggressive behavior. The patient reported with a prominent anterior gingival swelling of 6 mo duration which slowly enlarged in size and associated with multiple lymph node involvement. Microscopic examination of the lesion using H, E and immunohistochemical diagnosis confirmed the diagnosis as BL. The patient succumbed to the disease before any therapy could be instituted. Since a wide array of causes can be attributed to gingival enlargements, it is necessary to consider malignancies as one of the important differential diagnosis so as to facilitate the need for appropriate diagnosis and prompt treatment.  相似文献

BackgroundWe aimed to evaluate the effectiveness of different antibody therapies on nasal polyp symptoms in patients treated for severe asthma.MethodsWe performed a retrospective analysis of patients with severe asthma and comorbid CRSwNP who were treated with anti‐IgE, anti‐IL‐5/R or anti‐IL‐4R. CRSwNP symptom burden was evaluated before and after 6 months of therapy.ResultsFifty patients were included hereof treated with anti‐IgE: 9, anti‐IL‐5/R: 26 and anti‐IL‐4R: 15 patients. At baseline median SNOT‐20 was similar among groups (anti‐IgE: 55, anti‐IL‐5/R: 52 and anti‐IL‐4R: 56, p = 0.76), median visual analogue scale (VAS) for nasal symptoms was 4, 7 and 8 (p = 0.14) and VAS for total symptoms was higher in the anti‐IL‐4R group (4, 5 and 8, p = 0.002). After 6 months SNOT‐20 improved significantly in all patient groups with median improvement of anti‐IgE: −8 (p < 0.01), anti‐IL‐5/R: −13 (p < 0.001) and anti‐IL‐4R: −18 (p < 0.001), with larger improvement in the anti‐IL‐4R group than in anti‐IgE (p < 0.001) and anti‐IL‐5/R (p < 0.001) groups. VAS nasal symptoms improved by median anti‐IgE: 0 (n.s.), anti‐IL‐5/R: −1 (p < 0.01) and anti‐IL‐4R: −3 (p < 0.001), VAS total symptoms by anti‐IgE: −1 (n.s.), anti‐IL‐5/R: −2 (p < 0.001) and anti‐IL‐4R: −2 (p < 0.001).ConclusionsTreatment by all antibodies showed effectiveness in reducing symptoms of CRSwNP in patients with severe asthma, with the largest reduction observed in anti‐IL‐4R‐treated patients.  相似文献

目的 通过对帕金森病患者及正常对照组进行经颅超声(transcranial sonography,TCS)检查,结合帕金森病患者的Hoehn Yahr(H Y)分级及帕金森病统一评分量表评分结果,了解我国大陆地区帕金森病患者有无黑质(substantia nigra, SN)回声增强表现。方法 对入选对象进行TCS检查,并对检查结果进行评价。结果 帕金森病患者 SN阳性率明显高于正常对照者(P<0.05)。帕金森病SN异常组 H Y 分期明显高于帕金森病SN正常组(P<0.05),表明帕金森病患者SN高回声面积与H Y分期相关。TCS检查对帕金森病的敏感性为80.5%,特异性为79.9%。结论 我国帕金森病患者SN强回声检出率显著高于对照组,说明我国帕金森病患者也存在SN回声增强这一现象,与国内外报道相一致。TCS检查对帕金森病的诊断具有一定的意义,敏感性及特异性较高。  相似文献
