河豚鱼中毒15例的救治体会

目的探讨河豚鱼中毒的治疗方法及影响预后的因素。方法回顾性分析我院1996年1月-2006年4月收治的15例河豚鱼中毒的病例资料。结果15例均有恶心、呕吐，腹痛，口唇、舌尖、指端麻木，四肢乏力，外周血白细胞计数增高，肝功能损害5例，心电图可见房室传导阻滞6例。1例于中毒后16h死于呼吸循环衰竭。结论目前河豚鱼中毒尚无特效解毒剂，死亡率50％，死亡主要原因为脑干麻痹，导致呼吸循环衰竭。主张尽早清除毒物，应用维生素B1，B6，B12等以及士的宁注射治疗神经肌肉麻痹，有呼吸衰竭者尽快行气管插管机械通气辅助呼吸。     

Intracranial Extramedullary Hematopoiesis in β-thalassemia Major

A case of β-thalassemia major with a huge mass of hernatopoictic tissuc firmly attached tothe dura mater was reported This is the first case reported in China.     

A magnetic resonance imaging study of putamen nuclei in major depression.

The basal ganglia are recognized as putative mediators of certain cognitive and behavioral symptoms of major depression. Moreover, patients with basal ganglia lesions have repeatedly exhibited significant affective symptomatology, including apathy, depressive mood, and psychosis. Using high resolution, axial T2 intermediate magnetic resonance images, and a systematic sampling stereologic method, we assessed putamen nuclei volumes in 41 patients with major depression (DSM-III) and 44 healthy volunteer controls of similar age. Depressed patients had significantly smaller putamen nuclei compared with controls. Age was negatively correlated with putamen size in both groups. These results are the first demonstration of diminished putamen volumes in depression and further support a role for basal ganglia structures in the etiopathogenesis of depression.     

Tagawa髋臼旋转截骨术治疗髋臼发育不良的评价

目的　评价Tagawa髋臼旋转截骨术治疗髋臼发育不良的临床效果。方法　采用Tagawa髋臼旋转截骨术治疗髋臼发育不良 ,用Harris评分和测量X线髋臼指数来评估手术的临床效果和髋臼 股骨头解剖关系的变化。结果　Harris评分从术前的平均 ( 80± 7.7)分提高到 ( 95± 1.8)分 ,主要表现为疼痛明显改善。X线显示髋臼CE角、AC角、AHI获得明显改善 ,但HLI没有变化。所有病例没有重大并发症发生。结论　Tagawa髋臼旋转截骨术治疗髋臼发育不良能较好地重建髋臼和股骨头的解剖关系 ,可以明显改善患者髋部疼痛症状 ,延迟髋关节骨关节病的发生     

B组轮状病毒WH-2株vp7基因的原核表达与抗体的制备

目的：在大肠杆菌中表达人B组轮状病毒WH-2株VP7蛋白并制备其兔抗血清。方法：根据B组轮状病毒（GBRV）WH-2株vp7基因的全序列设计引物,用PCR的方法扩增得到vp7基因的编码区。将其克隆到原核GST融合表达载体pGEX-KG内,转化大肠杆菌E.coliDH5α,IPTG诱导表达人B组轮状病毒WH-2株VP7蛋白,经SDS-PAGE分离纯化表达的蛋白免疫新西兰兔,制备人B组轮状病毒WH-2株VP7蛋白抗血清。结果：经鉴定确认,vp7基因以正确的方式插入到载体中,此重组表达载体经IPTG诱导后,可表达相对分子量为53.4 kDa的GST-VP7融合蛋白。制备的抗血清经同样诱导表达的表达载体pGEX-KG表达产物吸收后1：500倍稀释后用Western Blot分析,与53.4 kDa的GST-VP7融合蛋白获得特异性显色信号。结论：人B组轮状病毒WH-2株VP7蛋白成功在大肠杆菌中GST融合表达,所表达的蛋白和制备的抗体不但为研究结构与功能提供了物质基础,也为GBRV所引起的疾病预防、诊断和治疗等流行病学研究和临床诊断奠定了基础,具有重要实际应用价值。     

Point mutation in the parkin gene on patients with Parkinson’s disease

Summary To investigate the distribution of possible novel mutations from parkin gene in variant subset of patients with Parkinson’s disease (PD) in China and explore whether parkin gene plays an important role in the pathogenesis of PD, 70 patients were divided into early-onset group and late-onset group; 70 healthy subjects were included as controls. Genomic DNA from 70 normal controls and from those of PD patients were extracted from peripheral blood leukocytes by using standard procedures. Mutations of parkin gene (exon 1–12) in all the subjects were screened by PCR-single strand conformation polymorphism (SSCP), and further sequencing was performed in the samples with abnormal SSCP results, in order to confirm the mutation and its location. A new missense mutation Gly284Arg in a patient and 3 abnormal bands in SSCP electrophoresis from samples of another 3 patients were found. All the DNA variants were sourced from the samples of the patients with early-onset PD. It was concluded that Parkin point mutation also partially contributes to the development of early-onset Parkinson’s disease in Chinese.
