超高CD34+采集的动员方案序贯二次自体造血干细胞移植治疗难治性 霍奇金淋巴瘤

目的:探讨超高CD34+采集的动员方案后序贯二次自体造血干细胞移植治疗难治性霍奇金淋巴瘤的疗效和安全性。方法:对1例经过多疗程一线、二线、新药、免疫等均难治的霍奇金淋巴瘤患者，予以IA+C方案化疗+G-CSF动员干细胞后采集出超高水平CD34+细胞，之后行自体造血干细胞移植，移植后获得完全缓解，再予序贯第二次自体造血干细胞移植进行巩固治疗。结果:总计输注单个核细胞数13.67×108/kg，CD34+细胞48.68×106/kg，第一次自体造血干细胞移植术后第7天造血功能恢复，复查全身PET-CT提示获得完全缓解，第二次自体造血干细胞移植术后第8天造血功能恢复，两次自体造血干细胞移植相关并发症均在可控范围内。结论:超高CD34+细胞采集的IA+C方案化疗+G-CSF动员可以让患者有机会进行多次自体造血干细胞移植，是临床动员的创新方案。对于难治性霍奇金淋巴瘤，序贯二次自体造血干细胞移植可达到更深层次缓解，且安全性较高，延长患者无疾病生存期及总生存期，为难治性霍奇金淋巴瘤治疗提供更多临床依据。     

2016至2018年某医院真菌血流感染者流行病学特征及耐药性分析

目的分析真菌性血流感染的病原菌分布以及耐药特征，为真菌血流感染的早期合理用药提供理论依据。 方法回顾性分析武汉大学人民医院2016年1月至2018年12月收治的真菌性血流感染者的菌群、科室分布以及耐药性。 结果入组192例真菌血流感染者的血培养样本中共分离192株真菌，其中白色念珠菌检出率为31.77%（61/192），其次热带念珠菌检出率为18.75%（36/192）；重症医学科检出率最高为33.85%（65/192）。所有菌株均对两性霉素B敏感，对其他抗菌药物耐药率分别为5-氟胞嘧啶4.49%（9/192）、伊曲康唑5.73%（11/192）、氟康唑10.94%（21/192）和伏立康唑11.46%（22/192）；除两性霉素B外，2016至2018年真菌对其他抗菌药物的耐药率均逐年上升，其中2018年所分离192株光滑念珠菌对伊曲康唑耐药菌率达46.7%。 结论真菌血流感染病原菌以念珠菌属为主，对目前抗真菌药物具有较高敏感性，但耐药率逐年上升，加强监测血培养病原菌变化及耐药趋势对指导临床用药至关重要。     

Genetics of epilepsy: epilepsy research foundation workshop report.

The Sixth Epilepsy Research Foundation workshop, held in Oxford in March 2006, brought together basic scientists, geneticists, epidemiologists, statisticians, pharmacologists and clinicians to consider progress, issues and strategies for harnessing genetics to improve the understanding and treatment of the epilepsies. General principles were considered, including the fundamental importance of clear study design, adequate patient numbers, defi ned phenotypes, robust statistical data handling, and follow-up of genetic discoveries. Topics where some progress had been made were considered including chromosomal abnormalities, neurodevelopment, hippocampal sclerosis, juvenile myoclonic epilepsy, focal cortical dysplasia and pharmacogenetics. The ethical aspects of epilepsy genetics were reviewed. Principles and limitations of collaboration were discussed. Presentations and their matched discussions are produced here. There was optimism that further genetic research in epilepsy was not only feasible, but might lead to improvements in the lives of people with epilepsy.     

Interleukin 17-Producing γδT Cells Increased in Patients with Active Pulmonary Tuberculosis

Although it has been known that y8 T cells may play an important role in the immune response to infection of Mycobacterium tuberculosis (M. tb), the mechanisms by which the T8 T cells participate in the innate and/or acquired immunity to tuberculosis (TB) have not been full elucidated. In the present study, 27 patients with active pulmonary TB and 16 healthy donors (HD) were performed. We found that proportion of IL-17-producing cells among lymphocyte was similar between TB patients and HD, whereas the proportions of γδ T cells in IL-17- producing cells (59.2%) and IL-17-producing cells in γδ T cells (19.4%) in peripheral blood were markedly increased in TB patients when compared to those in HD (43.9% and 7.7%, respectively). In addition, the proportions of IFN-γ-producing γδ T cells in TB patients were obviously lower than that in HD. Upon re-stimulated with M. tb heat-treated antigen (M. tb-HAg) in vitro, fewer IL-17-producing γδ T cells were generated from HD and TB patients, whereas IFN-γ-producing γδ T cells were increased in TB patients compared to that in HD. Our findings in TB patients and healthy human were consistent with other murine investigation that the IL-17- producing γδ T cells were main source of IL-17 in mouse model of BCG infection, suggesting that γδ T cells might be involved in the formation of tubercular granuloma in pulmonary TB patients, but need further identification.

消炎痛栓致低血容量休克1例

病人，男，84岁，因左侧肢体活动不便14h，加重伴短暂意识不清2h，于2005年9月22日以脑出血收入院，病人体型消瘦。10月3日病人发热，体温38.5℃左右，遵医嘱给予消炎痛栓一枚肛入，30min后体温降至36.0℃，继之全身湿冷，大汗淋漓，表情淡漠，脉搏细弱，呼吸急促，测血压7/5.3kPa，立即给予吸氧5L/min、706代血浆、复方氯化钠注射液补充血容量，多巴胺注射液入液静脉输注，并及时更换被汗浸湿的被褥，擦干身体，有效保暖。密切监测生命体征及病情变化。1h后测体温35.6℃，脉搏100/min、血压10.7/8.0kPa，尿量50mL。15h后病人意识清楚，表情正常，测体温36.8℃，脉搏82/min，呼吸19/min，血压13.3/10.0kPa，考虑为低血容量性休克，该对症治疗病情稳定。
