过敏性紫癜中医证治

过敏性紫癜小儿多见,也有部分成人发病。病因有外感和内伤,病机有虚实,实则热毒迫血妄行,虚则阴虚内热伤络,气虚失于统摄;病情迁延则气虚致瘀,瘀血阻络又易导致血液溢于脉外而复发。小儿外感因素居多,成人与饮食、情志和劳伤等因素更密切。发病无明显季节性,外感风、寒、暑、湿、燥、火均可致病。有阳络伤和阴络伤以及伤经络和伤脏腑不同＂,阳络伤则血外溢,阴络伤则血内溢＂＂,斑出阳明,疹出太阴＂。临床证型有热毒伤络、阴虚火旺、气不摄血和瘀血阻络等,热毒伤络型带有明显外感特征,其余三个证型则表现为内伤特征。前者多以疏风清热或清热解毒联合凉血止血方法,其余三个证型则滋阴清热或降火、健脾益气摄血或活血化瘀止血等。治疗体现止血、消瘀、宁血、养血总纲。

从督脉探讨扶阳理论在针灸临床中的应用

扶阳理论以阴阳为总纲,重视阳气,主张阳主阴从。通过针对督脉的诊治,可以最大限度地激发人身之阳气,促成扶阳之效。在针灸临床上,督脉为阳脉之海,总督诸阳,联系脏腑,故根据督脉的生理基础和病候表现,提出通督扶阳和补督扶阳的方法,治疗脑卒中后手足浮肿、痉挛性瘫痪、腰椎间盘突出症、肌萎缩侧索硬化症、五更泻、类风湿性关节炎等疗效显著。应准确辨证,通补结合,方能达到最佳扶阳的效果,祛除病邪。

异基因造血干细胞移植后的巨细胞病毒肠炎24例分析

目的 分析异基因造血干细胞移植(allo-HSCT)后巨细胞病毒(GMV)肠炎的临床特点、诊断方法和危险因素.方法 总结北京市道培医院2007年8月至2009年7月确诊的24例CMV肠炎患者的一般临床资料和内窥镜、组织病理学和病毒学检查结果,以及CMV肠炎与CMV病毒血症和移植物抗宿主病(GVHD)的关系.结果 87.5%的患者年龄≥18岁,诊断CMV肠炎的中位时间为allo-HSCT后第63天.内窥镜下的肠黏膜表现对区分单纯CMV肠炎和肠炎合并GVHD没有鉴别意义.用于诊断的方法包括组织病理学(32.1%)和病毒学(92.9%)检查.肠黏膜标本中每106个单个核细胞的CMV DNA定量大于105时更有诊断价值.在死亡和存活两组患者中进行了下列危险因素的比较:移植类型、预处理方案、更昔洛韦预防病毒天数、确诊肠炎前有无Ⅱ～Ⅳ度急性GVHD、GVHD确诊时间、是否使用≥1 mg/kg的甲泼尼龙治疗GVHD、GVHD距离确诊肠炎的时间、肠炎前是否有CMV血症、确诊肠炎的时间、肠黏膜CMV DNA定量,差异均无统计学意义.结论 进行内窥镜检查并通过组织病理学和病毒学检查确诊是CMV肠炎诊断中的决定性因素,最好进行全结肠检查并到达回肠末端.PCR方法能明显提高CMV检出率.对那些无法进行肠镜检查的患者,采用粪便检测CMVDNA能够对诊断提供帮助.

Abstract：

Objective To analyse the clinical features, diagnostic methods and risk factors of cytomegalovirus(CMV) enteritis after allogeneic hematopoietic stem cell transplantation(allo-HSCT).Methods Analysis was made on 24 cases of CMV enteritis after allo-HSCT in Beijing Daopei Hospital from Aug.2007 to Jul.2009, including clinical data, endoscopic diagnosis, histopathological and virological results, and the association between CMV enteritis with viremia and graft-versus-host disease(GVHD).Results 87.5% of the patients were over 18 years old.The median time to diagnosis of CMV enteritis was 63 days after HSCT.The mucosal lesions in enteroscopic examination had no significant differences between CMV enteritis and gastrointestinal GVHD complicated with the enteritis.The methods used in diagnosis included histopathology (32.1%) and virology (92.9%).The copies of CMVDNA in mucosal samples greater than 105/106 PBNC was better diagnosis.A number of risk factors were compared between the survival and death groups: type of transplant, conditioning regimen, the time span of ganciclovir prophylaxis therapy, grade Ⅱ - Ⅳ GVHD before enteritis, the time of diagnosis as GVHD, using MP≥1 mg,/kg to treat GVHD, the time between GVHD and enteritis, CMV viremia before enteritis, the time of diagnosis as enteritis, CMVDNA quantitation, and there were no any statistic differences.Conclusion Cytomegalovirus enteritis should be carefully diagnosed by histopathology and virology through endoscopic examination.It is better to undertake pan-colon endoscopy as well as terminal ileum examination for more accurate diagnosis.PCR can significantly improve the detection rate.CMVDNA detection in patients' stool may be helpful to diagnosis, especially for those patients who can not stand the endoscopy examination.     

甲状腺乳头状增生活跃与微小乳头状癌的诊断与鉴别诊断

目的 探讨甲状腺乳头状增生活跃与微小乳头状癌(PMC)的诊断与鉴别诊断.方法 收集PMC 100例,结节性甲状腺肿伴乳头状增生活跃53例.对比两者病理形态特征、流行病学及外科治疗方式,并检测CK19、HBME-1、galectin-3、CD56和p63的表达.结果 100%(53/53)的乳头状增生活跃出现具有纤维血管轴心的真性乳头,73.6%(39/53)伴2级及以上分支.无1例出现典型毛玻璃核、核明显异型重叠、包涵体等微小乳头状癌的细胞核特征,亦无间质硬化及浸润特征.甲状腺PMC中98.6%(73/74)CK19、HBME-1和galectin-3出现弥漫强阳性,而乳头状增生活跃组中无1例出现.结论 乳头状增生活跃可出现2级分支的真性乳头,但不出现典型毛玻璃核、核异型、核内包涵体等微小乳头状癌的典型细胞学特征,把不具有细胞学特征的真性乳头诊为乳头状癌一定要慎重.CK19、HBME-1、galectin-3三者弥漫强阳性是鉴别乳头状增生活跃及微小乳头状癌的非常有意义的指标.     

单倍体相合造血干细胞联合脐带血间充质干细胞移植治疗急性重型再生障碍性贫血的疗效观察

本研究探讨单倍体相合造血干细胞移植联合脐带血间充质干细胞治疗重型再生障碍性贫血(SAA)的方法和疗效。对5例SAA的患者进行了单倍体相合造血干细胞移植。移植物选择单倍体相合供者骨髓或外周造血干细胞加脐带血间充质干细胞。观察移植后临床造血重建时间及近期并发症。结果显示,所有SAA患者移植后均获得造血重建,白细胞计数大于2×109/L的平均时间是13.8天,血小板计数大于20×109/L的平均时间是17.8天,第30天行患者外周血STR-PCR检测显示为完全供者的基因型。除1例发生癫痫失去联系外,其余4例均无病存活至今,仍在继续随访中。总之,单倍体相合造血干细胞联合脐带血间充质干细胞移植是治疗急性SAA有效可行的方法,但还须大样本的研究。

白血病患者并发真菌肺炎行异基因移植7例临床分析

目的观察并发曲霉菌肺炎的白血病患者行异基因外周血造血干细胞移植的疗效及安全性。方法回顾性分析7例伴曲霉菌肺炎的白血病患者成功完成异基因外周血造血干细胞移植的过程。结果入组7例患者中,男4例,女3例,中位年龄22.8（13-37）岁,随访时间均大于6个月,移植后1个月复查患者嵌合体均为100%完全供者嵌合。移植后平均抗真菌治疗时间为3个月,7例患者肺部真菌感染全部达到显效,造血干细胞100%植入,无1例发生相关死亡。结论伴发曲霉菌肺炎的白血病患者采用有效的抗真菌治疗方案仍然可以接受异基因外周血造血干细胞移植,并不会影响供者造血干细胞植入,且患者耐受性良好,值得进一步研究。     

异基因造血干细胞移植后早期EB病毒激活的监测和抢先治疗

目的 研究异基因造血干细胞移植(allo-HSCT)后早期EB病毒(EBV)激活的监测及其抢先治疗的结果和预后.方法 以2007年1月至2009年1月在我院行allo-HSCT并连续监测血浆EBV DNA的277例患者为研究对象,其中亲缘人类白细胞抗原(HLA)单倍型移植116例;非血缘移植75例,同胞相合移植86例.预处理主要采用马利兰(BU)+环磷酰胺(CY)/氟达拉滨(Flu)或全身照射(TBI)/Flu方案,此外,亲缘单倍型和非血缘移植加用抗胸腺细胞球蛋白(ATG).移植后最初的3个月内每周采用实时定量PCR(RQ-PCR)方法检测血浆EBV DNA,若＞5×102拷贝/ml而无临床症状时诊断为EBV血症.抢先治疗主要应用阿昔洛韦10 mg/kg静脉点滴,每8小时1次,同时在情况允许时减少免疫抑制剂.结果 移植后100 d(+100 d)内33例(11.9%)患者发生EBV血症,中位时间为+44(+19～+84)d;EBV血症的发生率在同胞相合、亲缘单倍型和非血缘移植中分别为0、15.5%和20.0%,在亲缘单倍型与非血缘移植中EBV血症的发生率差异无统计学意义(P=0.09),但均较同胞相合移植高(P=0.001).33例患者均首先采用减少免疫抑制剂剂量和阿昔洛韦抢先抗病毒治疗,其中20例患者病毒血症转为阴性,治疗有效率为60.6%,中位时间为治疗后11(4～56)d,抗病毒治疗疗程的中位时间为21(14～60)d.单因素及多因素分析均表明,亲缘单倍型移植、非血缘移植以及Ⅱ～Ⅳ度急性移植物抗宿主病(aGVHD)是EBV血症发生的高危因素.发生EBV血症患者(33例)比未发生EBV血症患者(244例)的2年预期生存率明显降低(54.2%比72.1%,P=0.006).结论 allo-HSCT后用RQ-PCR监测血浆EBV DNA载量可以及时确定EBV血症并给予抢先抗病毒治疗,且大多数患者对抢先治疗有完全反应,这样有利于减少高危患者EBV相关疾病的发生率和病死率;亲缘单倍型移植、非血缘移植及Ⅱ～Ⅳ度aGVHD是EBV血症的高危因素;EBV血症对allo-HSCT后患者的生存有负面影响.

Abstract：

Objective To investigate early Epstein-Barr virus (EBV) reactivation and the outcome of preemptive therapy after allogeneic hematopoietic stem cell transplantation (allo-HSCT). Methods From January 2007 to January 2009, totally 277 patients after allo-HSCT were studied (haploidentical 116,unrelated 75, matched sibling 86). Conditioning regimens were mainly busulfan (BU) + cyclophosphamide ( CY)/fludarabine(Flu) or total body irradiation (TBI) + CY/Flu. Antihuman thymocyte globulin (ATG)was added in haploidentical and unrelated transplants. Plasma EBV DNA was monitored once to twice weekly in the first 3 months after allo-HSCT with real time quantitative polymerase chain reaction (RQ-PCR). EBV viremia was diagnosed when EBV DNA was more than 5 × 102 copies/ml but without symptoms. Acyclovir (10 mg/kg, intravenous drip, 8 h) was used for preemptive therapy and immnuo-suppressants were decreased if possible. Results Totally 33 patients ( 11.9% ) developed EBV viremia with a median time at day 44 (day 19 to day 84). The incidences of EBV viremia in the transplants from matched sibling,haploidentical, unrelated donors were 0, 15.5%, 20. 0%, respectively. There was no significant difference between haploidentical and unrelated transplants ( P = 0. 09 ), but much less EBV viremia was seen in matched sibling transplant ( P = 0. 001 ). Twenty of 33 patients ( 60. 6% ) had complete response to preemptive therapy. The median time to reach EBV DNA negative in plasma was 11 (4-56) d. The median duration of preemptive therapy was 21 (14-60) d. Both univariate and multivariate analysis indicated that haploidentical and unrelated transplants, acute graft versus host disease (GVHD) were the risk factors for EBV viremia. Two-year overall survival in the patients with EBV viremia was significantly lower than that without EBV viremia (54. 2% vs 72. 1%, P = 0. 006 ). Conclusions Our large clinical study has demonstrated that preemptive therapy with acyclovir that is guided by EBV viremia is effective in majority of the patients with high-risk for EBV reactivation after allo-HSCT, which may further decrease the risk for developing life-threatening EBV disease or post-transplantation lymphoproliferative disorder. Haploidentical and unrelated transplants, acute GVHD are the risk factors for EBV viremia which has negative impact on survival.
