干扰素在恶性淋巴瘤自体移植后早期干预的应用

目的:观察非霍奇金淋巴瘤（non-Hodgkin's lymphoma，NHL）患者自体造血干细胞移植（autologous hematopoietic stem cell transplantation，ASCT）术后应用重组人α-2b干扰素（α-2b IFN）进行早期干预治疗的临床疗效。方法:选取18例行ASCT的NHL患者为研究对象，移植前疾病评估均未达到完全缓解（complete remission，CR），试验组血象恢复后给予IFN 3 000 000 U次/隔日干预治疗，3个月后停用；对照组未行干扰素干预治疗，分析总体疗效及两组对比的生存情况。结果:随访中位时间为34（10~50）个月，患者中位生存时间为37（31~45）个月，3年总体无进展生存（progressive free survival，PFS）、总生存（overall survivial，OS）分别为54.7%、66.8%。ASCT后试验组1年内无疾病复发，2年内复发率为12.5%；对照组1年内复发率为20%，2年内复发率为30%。结论:NHL患者在ASCT后给予重组人α-2b IFN早期干预治疗，患者耐受性好，可能降低移植后早期复发率。

Utility of quantitative EEG in early Lewy body disease

IntroductionThe reduction of background activity and the increase of low-frequency powers on electroencephalogram (EEG) correlate with cognitive impairment and have been suggested to be underpinned by cholinergic deficit. We aimed to investigate the ratio between α and θ band power (α/θ ratio), as a synoptic index of quantitative EEG (qEEG) slowing-down, in a peculiar group of patients with mild cognitive impairment (MCI) due to an early-stage Lewy body disease (MCI-LBD), as compared to de novo PD patients without cognitive impairment (PD-MOT), to patients with MCI due to Alzheimer's disease (MCI-AD), and to healthy controls (HC).MethodsTwelve patients with MCI-LBD (8 males; mean age 74.8 ± 3.6), 11 PD-MOT, 11 MCI-AD and 24 HC subjects undergoing qEEG were matched for gender, age, and education. Following logarithmic transformation, the α/θ ratio was compared among groups and brain regions by repeated measures ANOVA, also exploring group*regions interactions.ResultsA significant effect of group (p = 0.0003), regions (p = 0.0001), and group*regions interaction (p = 0.0001) on the α/θ ratio was observed. At post-hoc analysis, α/θ ratio was significantly lower in MCI-LBD (p = 0.001) and in PD-MOT (p = 0.02) compared to HC, and in MCI-LBD than MCI-AD (p = 0.05). No significant differences were found between MCI-AD and HC, as well as between MCI-LBD and PD-MOT.ConclusionThe α/θ power ratio as a synoptic index of EEG background slowing-down could be a simple and easy-to-use qEEG index which might indirectly mirror a cholinergic failure, useful to pick-up those MCI patients at higher risk of developing a Lewy-body disease.     

聚乙二醇干扰素α联合利巴韦林治疗难治性慢性丙型肝炎过程中血常规变化与疗效的相关性

目的观察难治性慢性丙型肝炎标准治疗过程中血常规的变化与抗病毒疗效的关系。方法收集2011年9月-2012年12月于首都医科大学附属北京佑安医院就诊的难治性慢性丙型肝炎初治患者63例,给予聚乙二醇干扰素α-2a(180μg/周)联合利巴韦林治疗48周,分别在基线、治疗4、12、24、48周和随访24周时进行HCV RNA及血常规的检测,分析血常规与疗效的相关性。根据是否获得持续病毒学应答(SVR),分为SVR组和n SVR组。计量资料组间比较采用t检验,计数资料组间比较采用χ2检验;采用简单线性相关分析法进行相关性分析。结果 63例患者有3例失访,余下60例均完成抗病毒治疗和24周随访,其中46例获得SVR,SVR率为76.7%;SVR组患者治疗4、12、24周时的淋巴细胞计数(LYPH)、白细胞计数(WBC)及中性粒细胞计数(NUET)均低于n SVR组,并且在12周时差异均有统计学意义(t值分别为3.398、2.766、2.037,P值均0.05),在24周时两组WBC及NUET差异亦均有统计学意义(t值分别为2.559、2.151,P值均0.05);此外SVR组患者在治疗4周时上述3项指标较基线的下降幅度均大于n SVR组,其中LYPH下降幅度在两组间差异有统计学意义(t=2.26,P=0.03)。LYPH、WBC、NUET在治疗4、12周时与HCV RNA的下降幅度呈正相关(r值分别为0.36、0.45、0.37、0.47、0.61、0.33,P值均0.05)。结论血常规中LYPH、WBC及NEUT的变化及下降幅度在一定程度上可作为难治性慢性丙型肝炎抗病毒疗效的预测指标。     

Erythema induratum of Bazin in a 10‐year‐old boy

Erythema induratum of Bazin (EIB) is a form of tuberculid resulting from hypersensitivity to tuberculosis antigen. EIB occurs most commonly in middle‐aged women and is not typically seen in children. Here, we present a rare case of EIB, presenting as a chronic nodular panniculitis, in a 10‐year‐old Korean boy.
