Effect of Triptolide on Expression of Receptor Activator of Nuclear Factor-κB Ligand in Rat Adjuvant Induced Arthritis

Receptor activator of nuclear factor-kappaBligand(RANKL)promotes osteoclast formation,fusion,differentiation and activation.It plays akey role in osteoclast mediated bone erosion inrheumatoid arthritis(RA).Osteoprotegerin(OPG),as a soluble decoy receptor of RANKL,can prevent bone erosion in RA.Our previousstudies have shownthat Triptolide(TP),an activecompoundidentifiedin a traditional Chinese herb--Tripterygium wilfordii Hook F(TWHF),can ef-fectively inhibit bone destruction in ex…

2005年上海市霍乱弧菌菌株表型及ctxA毒力基因分析

目的：分析本市2005年不同来源01群和0139群霍乱弧菌菌株表型和ctxA毒力基因特征。方法：以PCR方法，对所有菌株进行ctxA毒力基因检测。采用WHO推荐的改良K—B纸片法，对所有菌株均进行了12种抗菌药物的药敏试验。结果：从病人和外环境中分离出的0139群霍乱弧菌均为产毒株；从病人中分离出的01群霍乱弧菌流行株均产毒，外环境中分离出的非流行株少数也产毒。0139群霍乱弧菌菌株耐药谱较01群霍乱弧菌菌株广；两者对氨苄青霉素、强力霉素、庆大霉素、复方新诺明、利福平耐药率有显著差异。结论：本市2005年霍乱的流行株都是产毒株，但产毒株不一定是流行株。药敏结果显示，对01群和0139群霍乱弧菌应采取不同抗菌治疗，0139群霍乱弧菌多重耐药应引起重视。     

结肠镜在结直肠外科疾病中的诊治

目的探讨应用结肠镜(内镜)对常见结直肠外科疾病的诊治,以提高利用内镜进行诊治的安全性及疗效。方法回顾2001~2005年间1231例行内镜诊治的病人,其中行内镜治疗76例,包括大肠息肉62例、乙状结肠扭转4例、假性结肠梗阻5例及急性结肠出血5例。总结操作体会,分析疗效及并发症的原因。结果内镜下治疗62例大肠息肉,共132枚,无并发继发性出血及迟发性穿孔。21例结肠梗阻病人行内镜检查,19例明确梗阻原因及部位。对4例乙状结肠扭转行内镜下复位,3例成功,另1例经二次复位后仍复发,予以手术治愈。对5例假性结肠梗阻行内镜下减压,随访3个月,4例治愈。5例急性结直肠出血,4例发现出血灶,4例内镜下止血成功。结论内镜提高了结直肠外科疾病的诊治水平,创伤小,应用中要严格掌握适应证,改进操作技术,减少并发症。     

植入前遗传学诊断"知情同意"的影响因素与对策

植入前遗传学诊断（Preimplantation Genetic Diagnosis PGD）是辅助生育技术与分子生物学技术相结合而发展的孕前遗传学诊断技术,在植入子宫前淘汰了遗传异常的胚胎,是产前诊断技术的重大进展.但是,由于技术本身存在着一定局限性和不确定性,同时,受到病人认知能力等因素的影响,由此引发了系列伦理学争议.在进行PGD前,一个明了、详尽的患者知情同意过程是必须的.包括通俗全面告知PGD有关信息、手术和检测的局限性和可能结果;充分告知通过PGD所获得的利益和风险.在此基础上针对不同的遗传病检测签署详细的书面知情同意书.

Clinicopathologic and genetic profile of intracranial marginal zone lymphoma: a primary low-grade CNS lymphoma that mimics meningioma.

PURPOSE: Although rare overall, marginal zone B-cell lymphoma (MZBCL) is the most common primary low-grade CNS lymphoma reported in the literature. The aim of this study is to elucidate the biology and genetic features of this unusual tumor. PATIENTS AND METHODS: Fifteen CNS MZBCLs were studied clinically, pathologically, and genetically, including fluorescent in situ hybridization analyses with commercially available MALT1 and IgH break-apart and centromere 3, 7, 12, and 18 probes. RESULTS: CNS MZBCLs preferentially affect middle-aged women (female-to-male ratio, 4:1), with 93% presenting as dural-based masses mimicking meningioma. Ten patients with 1 to 7.6 years of follow-up after diagnosis showed no evidence of disease after radiation and/or chemotherapy. Like MZBCLs outside of the CNS, they consisted of CD20+, CD3- small B lymphocytes with varying degrees of plasmacytic differentiation and predominantly kappa light-chain restriction (78%). Lymphoid follicles with follicular colonization were seen in three patients and deposition of amyloid was noted in samples from two patients, one of which was tumefactive. Neither Bcl-6 protein nor Epstein-Barr virus-encoded RNA was expressed. Trisomy 3 was detected in six of 12 patients, with no rearrangements of MALT1 or IgH and no trisomies of 7, 12, or 18 detected. CONCLUSION: Our data suggest that intracranial MZBCL is an indolent primary CNS lymphoma that typically presents as a meningioma-like dural-based mass. Trisomy 3, but not MALT1 or IgH translocation, is a common genetic abnormality that may contribute to the pathogenesis of this CNS lymphoma.     

老年原发性高血压患者血压昼夜节律与靶器官损害临床观察

目的探讨老年原发性高血压患者血压昼夜节律与靶器官损害的关系.方法入选年龄≥60岁老年原发性高血压病患者150例,通过24小时动态血压监测了解其血压昼夜节律变化,根据血压昼夜节律监测结果为非杓型组(夜间平均血压较白昼平均血压下降值＜10%)78例,另一对照组为杓型72例.所有入选患者检查:超声心动图、颈动脉超声、肌酐清除率、尿微量白蛋白.结果非杓型组的尿微量白蛋白定量和左心室质量指数均高于杓型组(p＜0.01);非杓型组的颈动脉内膜厚度大于杓型组(P＜0.05);左室射血分数和肌酐清除率小于杓型组(P＜0.05).结论血压昼夜节律消失是老年原发性高血压患者靶器官损害的重要危险因素.
