普外科住院患者营养状况评价

目的　调查本院 2 0 0 2～ 2 0 0 3年间普外科住院患者的营养状况。方法　采用多项营养评价指标测定 4 0 12例非急诊住院患者营养状况 ,分析年龄、疾病等因素与营养状况之间关系。结果　各项指标进行营养评价得出本院普外科非急诊患者营养不良的发生率分别是 :BMI 2 1 3% ,TSF5 0 6 % ,MAC 2 0 5 % ,AMC 2 1 2 % ,SGA 38 0 % ,MNA 2 0 8% ,ALB 2 4 2 % ,PA 35 4 % ,TLC 5 5 8%。 >6 0岁组老年患者、消化道疾病患者及恶性肿瘤患者营养不良发生率分别高于≤ 6 0岁患者、消化道外疾病患者及良性疾病患者 ,差异有显著性 (P <0 0 5 )。结论　本院普外科住院患者的营养不良发生率为 2 0 5 %～ 5 5 8% ,不同的营养评价指标得出的营养不良发生率不同。     

Rapid Immunofluorescence Microscopy for Diagnosis of Melioidosis

An immunofluorescent (IF) method that detects Burkholderia pseudomallei in clinical specimens within 10 min was devised. The results of this rapid method and those of an existing IF method were prospectively compared with the culture results for 776 specimens from patients with suspected melioidosis. The sensitivities of both IF tests were 66%, and the specificities were 99.5 and 99.4%, respectively.     

显露血管内皮下层纤维连接素的方法

本文报道了一种显露内皮下层纤维连接素的理想方法。大白鼠主动脉壁分别用1.0％NP-40作用5min,30.0mmol/L KCl作用10min后,内皮细胞全部脱离,内皮下层大部分纤维连接素被保留。本法适用于建立细胞与血管壁相互作用的体外实验模型。     

包皮过长和包茎组织中触觉小体观察

目的观察包茎和包皮过长组织中触觉小体差异情况。方法收集21~25岁年龄组包皮标本44例,按包皮解剖形态分为:①包茎组21例;②包皮过长组23例。用免疫组化方法对两组包皮标本中的触觉小体进行染色,在放大100倍的视野下观察和统计两组包皮标本中触觉小体总数以及视野的总数,并用卡方检验对两组间的差异进行统计学分析。结果两组标本中,分别有8个(8/21包茎组)和10个(10/23包皮过长组)标本中未发现触觉小体,其差异无显著性(P=0.717)。包茎组和包皮过长组中触觉小体的密度分别为33.1%和21.1%,差异具显著性(P=0.022)。结论包茎中触觉小体密度较包皮过长明显升高可能是一种生理性代偿机制,而两种包皮组织中触觉小体的消失可能遵循同一规律。     

Effect of nuclear factor-κB p65 ASOND on I typ collagen expression and rat hepatic stellate cells proliferation

Objective Sstudy effect of nuclear factor-κB ASOND on I type collagen expression and rat hepatic stellate cells(HSC)proliferation.Methods Rat HSCs were separated by affusing and digestingof Ⅳ type collagenenzyme and density acentric method.Lipid-mediated NF-κB p65 ASOND(0.001,0.01,0.1,1μmol/L)Was transferred into rat HSCs.Toxicity of HSCs caused by NF-κB p65 ASOND and activity of LDH were determined by trypan blue staining.Proliferation affection of transferring NF-κB p65 ASOND into HSCs was determined by MTT.In different concentration NF-κB p65 ASOND.expression of Ⅰ type collagen stimulated by 1mg/L TNF-αwas determined by RT-PCR and ELISA.Results After transfection of NF-κB p65 ASODN,expression of NF-κB protein in HSCs was decreasing.Toxicity experiment indicated that NF-κB p65 ASOND of different concentration(0.001,0.01,0.1 and 1.0 μmol/L)had no effect on HSCs livability and LDH activity(P<0.05).Four different concentration NF-κ B p65 ASOND could restrain HSCs proliferation stimulated by 1 mg/L TNF-α.The expression of I type collagen and mRNA stimulated by 1mg/LTNF-αwas increased,and had a positive correlation with concentration(P>0.05).Conclusion NF-κB p65 ASOND may depress NF-κB activity to restrain HSCs proliferation and Ⅰ type collagen expression,and reduce extracellular matrix.
