手助腹腔镜肝部分切除术治疗原发性肝癌

目的 探讨手助腹腔镜肝部分切除术治疗原发性肝癌的方法和应用价值。方法 经临床筛选的第Ⅱ、Ⅲ、Ⅵ段或边缘型的原发性肝癌6例，在腹腔镜辅助下．应用手助器、超声刀、切割器等特殊器械进行腹腔镜下肝癌切除术。结果 6例患者均成功完成手术，包括肝Ⅱ、Ⅲ段切除，Ⅵ段切除及非规则性肝段切除术，手术时间80～130min，术后住院6～9d，手术出血150～700ml，无中转开腹手术，无并发症。术后随访6～15个月，2例分别于手术后3和4个月肝内复发，其余4例随访至今无复发。结论 在经过临床选择的病例中，手助腹腔镜下作肝部分切除术治疗原发性肝癌是安全、可行的手术方式。     

A型肉毒毒素多表位串联体的设计、表达、纯化及鉴定

目的:设计、表达两个A型肉毒毒素多表位串联体.方法:从文献报道的A型肉毒毒素(botulinum neurotoxin type A,BoNT/A)的表位及生物信息学方法预测得到的B细胞表位中遴选表位,并加入适当的辅助性元件,设计多表位串联体A、B.对其基因进行优化后,经重叠PCR方法合成串联体A、B的全长基因.分别插入原核表达载体pQE-30,再转化E.coli M15[pREP4]感受态细胞中进行诱导表达,以金属螯合亲和层析法纯化重组蛋白,并进行鉴定.结果与结论:成功设计并构建了两个多表位串联体A、B,并在E.coli中以包涵体形式获得高效表达.Ni-NTA法纯化后分别获得纯度大于92.2%、99%的重组串联体A、B蛋白,并经透析复性法复性.Western印迹和间接ELISA显示纯化、复性后的重组蛋白与抗天然BoNT/A马血清有特异性结合反应.     

Survivin expression predicts poorer prognosis in anaplastic large-cell lymphoma.

PURPOSE: Survivin, a member of the inhibitor of apoptosis (IAP) family, is not detected in normal adult tissues but is overexpressed in various cancers, including some types of lymphoma. The frequency and prognostic significance of survivin expression in anaplastic large-cell lymphoma (ALCL) is unknown. Materials and METHODS: We assessed for survivin expression in 62 ALCL tumors (30 anaplastic lymphoma kinase [ALK]-positive and 32 ALK-negative) obtained before doxorubicin-based chemotherapy. Given that survivin is a target of the STAT3 signaling pathway and STAT3 is activated in ALCL, survivin expression was also correlated with STAT3 activation. RESULTS: Survivin was expressed in 34 tumors (55%) and did not correlate with ALK. A significant association between survivin expression and STAT3 activation was observed (P =.007, Fisher's exact test). For the ALK-positive group, the 5-year failure-free survival (FFS) was 34% for patients with survivin-positive ALCL compared with 100% for patients with survivin-negative ALCL (P =.009, log-rank test). For the ALK-negative group, the 5-year FFS was 46% for patients with survivin-positive tumors compared with 89% for patients with survivin-negative tumors (P =.03, log-rank test). Overall survival was similarly worse for patients with survivin-positive tumors in both the ALK-positive and ALK-negative groups. Furthermore, multivariate analysis confirmed the independent prognostic value of survivin expression, along with age older than 60 years and Ann Arbor stage III or IV. CONCLUSION: Survivin is expressed in approximately half of ALCL tumors and independently predicts unfavorable clinical outcome. Modulation of survivin expression or function may provide a novel target for experimental therapy in patients with ALCL.     

尿毒症患者的性激素变化及其临床意义探讨

目的 :探讨女性尿毒症患者卵巢功能障碍的发病情况及其临床意义。方法 :应用酶免疫法 (EIA)测定了2 3例更年期前女性尿毒症非透析患者、15例透析患者及 2 9例健康献血者中促卵泡素 (FSH)、泌乳素 (PRL)、促黄体素 (LH)、雌二醇 (E2 )及孕酮 (P)的水平。结果 :尿毒症女患者PRL、FSH及LH均较健康对照组升高 ,而孕酮值显著降低 ,对此均有显著差异 ;且尿毒症女患者PRL升高、孕酮值降低与肾小球滤过率 (GFR)呈明显相关。透析患者较非透析患者PRL升高更为明显 ,孕酮值亦较非透析患者有所升高 ,但无显著意义。结论 :尿毒症女患者的排卵障碍及月经紊乱等都与尿毒症的严重程度相平行。透析并不能改善尿毒症女患者的卵巢功能障碍 ,只有纠正与改善肾功能 ,才能使尿毒症女患者的卵巢功能得以改善     

以人为本理念在全程护理服务中的实践

为了探索既符合中国国情又能满足病人需求的护理服务新模式，浙江省台州市中心医院自2002年开始试行全程护理服务。在实施护理中以病人为中心，从理念上、环境上、权益上、细节上为病人提供全面、全员、全程的人本服务；在管理实践中，提倡“尊、理、信、谐、通、创”六字理念，将管理视为服务，实行人本管理。通过3年的实践，整体护理质量、病人满意度、护士对工作满意度均有显著提高。     

SOME ANATOMICAL DATA RELATED TO THE TRANSNASO- SPHENOIDAL RESECTION OF PITUITARY FOSSA TUMORS

Since the beginning of this century, trans- naso-sphenoidal resection of the pituitary fossa tumors has been widely used clinically. It has more merits than other operative approaches used before. In China it has been adopted by both ENT doctors and neurosurgeons since 1959.1 In order to afford some relevant anatomical data, we measured 137 adult sagittal plane skulls with distinct landmarks.     

5种真空采血促凝管在生化检验中的应用及评价

目的 评价五种真空采血促凝管对常规生化检测项目的影响。方法 采集健康体检者及自愿者血液标本100例,选用5个不同厂家生产的真空采血促凝管,与美国BD公司生产的无添加剂的血清管进行采血质量和生化检测对比评价。结果 5个厂家生产的真空采血促凝管与BD公司生产的无添加剂血清管在多数生化检验项目上无明显差异(P>O.05),但有3个国内厂家生产的真空采血促凝管在标本采集质量、分离效果上存在明显不足,且在血清K、LDH、HBD、CK、CHOL、TG、HDL-c、LDL-c、APOA、APOB等检测上与对照组间存在着显著差异(P<0.05且r相似文献
