改良骨科钳在骨科手术中的初步应用研究

目的初步观察改良骨科钳在骨科手术中的应用效果。方法按随机、前瞻、单盲、对照的原则，将100例骨干粉碎骨折患者分为两组：试验组（术中使用改良骨科钳组，50例）和对照组（术中使用骨科钳组，50例），重点观察两组患者术中操作，术后复位、内固定及骨折愈合情况等指标。结果试验组较对照组术中操作顺利、术后复位、内固定满意，骨折愈合良好（P〈0．05）。结论改良骨科钳在骨科手术中的应用，可使粉碎骨折达解剖复位，且减少手术创伤，缩短骨折愈合时间，增进功能恢复，缩短平均住院时间，降低医疗费用，值得进一步研究和临床推广。     

rhGM-CSF作为成人乙肝疫苗无(弱)应答者免疫佐剂初探

Objective To investigate the effect of recombinant human granulocyte macrophage colony stimulating factor (rhGM-CSF) as adjuvant on immune response in adults of non-and hyporesponders to hepatitis B vaccine. Methods Those who were once immunized with recombined yeast gene hepatitis B vaccine more than one standard scheme in two years and negative for hepatitis B markers were randomly sorted as group A and group B. 33 adults of group A were given hepatitis B vaccine 10 μg each time. The immune procedure was O, 1 and 6month. 34 adults of group B were given rhGM-CSF 300 μg for the first day, then 10 μg each time for routine immune. The blood samples were collected before the first injection and in 1, 2 and 8 months (T1, T2, TS)following the first injection to test Anti-HBs. Results Anti-HBs positive conversion rates of group A and B at T8 was 39.39% and 64.71% respectively(P=0.038). Anti-HBs levels of group B at TI, T2, T8 were(113.85±198.56) mIU/ml, (312.40±349.44) mIU/ml, (427.74±411. 58) mIU/ml (P=0.001). There was significant difference between group A and B in T8 Anti-HBs levels(P=0.010). Conclusion Better immune response was found in the group of rhGM-CSF with hepatitis B vaccine. So rhGM-CSF can induce the immune respond to hepatitis B vaccine.

前列腺特异性抗原在87例前列腺肿块病因分析中的应用

目的 对87例前列腺肿块进行病因分析，指导临床治疗。方法 应用血清免疫学及B型超声波对87例前列腺肿块患者进行分类筛选及试验性治疗，动态分析血清PSA变化以明确病因。结果 87例患者中急慢性细菌性前列腺炎43例，BPH及BPH合并慢性炎症28例，前列腺癌16例。结论 B—US结合血清PSA动态检测及抗菌试验性治疗基本可以鉴别出前列腺肿块的病因并指导临床治疗。     

Tc17细胞对乙肝相关慢加急性肝衰竭病情进展及乙肝病毒清除的影响

【目的】探讨Tc17细胞表达对乙肝相关慢加急性肝衰竭（HBV-ACLF）病情进展及乙肝病毒清除的影响。【方法】纳入43例HBV-ACLF患者,以20例慢性乙型肝炎患者（CHB）和12例健康体检者（NC）为对照,流式细胞术检测外周血中Tc17细胞的表达,荧光定量PCR法检测HBV-DNA载量,采用MELD、MELD-Na、CLIF-CACLF及AARC评分等指标评估患者病情,分析Tc17细胞表达对病情进展及乙肝病毒清除的影响。【结果】与NC组及CHB组比较,HBV-ACLF患者Tc17细胞表达明显升高（P<0.001及P=0.017）。相关分析发现Tc17细胞与AARC评分、MELD评分及MELD-Na评分均成正相关（r=0.504,P=0.001;r=0.417,P=0.005及r=0.382,P=0.012）,而与CLIF-CACLF评分有相关趋势（r=0.294,P=0.055）;且随着病情进展,Tc17细胞的表达逐渐升高。另外发现Tc17细胞与基线HBV-DNA载量成正相关（r=0.339,P=0.026）,且Tc17细胞高表达的HBV-ACLF患者4周后HBV-DNA下降较低表达组更明显（P<0.001）;多因素线性回归分析发现只有基线Tc17细胞及谷草转氨酶水平与HBV-DNA下降有关。【结论】Tc17细胞介导的炎症反应有助于清除HBV-DNA,但过激的炎症反应将导致患者病情进展。

三明市1071例尘肺患者致残等级分析

根据中华人民共和国劳动能力鉴定《职工工伤与职业病致残等级标准》(GB/T16180—2006),对1071例尘肺患者职业病致残鉴定等级进行统计分析。结果发现,致残等级与尘肺期别、肺功能损伤程度、接尘工龄均有统计学意义,提示尘肺的致残等级鉴定需要结合各种因素,在难以判定通气功能障碍程度时需作血气分析,呼吸困难有必要列入国家《职工工伤与职业病致残等级》鉴定标准。
