在深静脉血栓—肺栓塞病程中腔静脉滤器的应用价值分析

目的：探讨腔静脉滤器(Vena cava filter VCF)在深静脉血栓(Deep venous thrombosis DVT)—肺栓塞(Pulmonary embolism PE)病程中的应用价值。方法：结合本组25例高危深静脉血栓一肺栓塞患者，对其中24例置放5种构型的永久型或临时型下腔静脉滤器(IVCF)26枚的临床疗效、影响病程与预后因素及病生理改变，复习文献分析讨论。结果：DVT有可能脱落导致PE或致死性肺栓塞；置放IVCF可有效预防肺栓塞，早期进行溶栓治疗，改变预后。结论：严格按适应证植入IVCF，对DVT—PE的早期治疗和预防致死性肺栓塞有重要意义，但其应用价值需进行综合评价和进一步探讨。     

α-平滑肌肌动蛋白和β-肌动蛋白在瘢痕组织中的表达

目的 探讨α-平滑肌肌动蛋白(α-SMA)和β-肌动蛋白(β-actin)对增生性瘢痕形成的可能作用。方法 采用荧光定量PCR法检测10例增生性瘢痕和10例正常皮肤组织中α-SMA和β-actin的表达水平。结果 增生性瘢痕组织中α-SMA和β-actin表达水平均高于正常皮肤组织,差异有统计学意义(P<0.01)。结论 α-SMA和β-actin在瘢痕增生中起重要作用;由于β-actin在瘢痕组织和正常皮肤中的不恒定性,建议在瘢痕的mRNA定量研究中不作为内参照物。     

第三脑室脑膜瘤(九例报告及文献回顾)

目的探讨第三脑室脑膜瘤的组织发生学、临床特点和外科治疗。方法报道9例经影像学、手术和病理学证实的第三脑室脑膜瘤，并回顾相关文献。结果第三脑室前部脑膜瘤5例，第三脑室后部脑膜瘤4例，平均发病年龄25．6岁，无明显性别差异；最常见的症状是梗阻性脑积水，缺乏硬脑膜附着为其影像学特征。肿瘤全切除6例。结论第三脑室脑膜瘤是一种罕见的脑室内脑膜瘤，起源于中间帆脉络组织或脉络丛，经半球间裂-胼胝体-穹隆间入路是合理的手术路径选择。     

C端序列的删除对非出血重组蛇毒纤溶酶的影响

[目的]研究C端序列对非出血重组纤溶酶(rFⅡ)特异性、活性和热敏感性的影响.[方法]通过SOEing PCR方法构建删除C端序列的突变体,突变体和rFⅡ分别在P.pastoris中诱导表达.表达和纯化的蛋白用SDS-PAGE和Westeren blot进行鉴定.之后分析其生化特性.[结果]rFⅡ及突变体通过SDS-PAGE和Westeren blot得到证实.生化分析揭示:①突变体对显色底物N-(p-Tosyl)-Gly-Pro-Lys-pNA的催化效率(Kcat/Km)是rFⅡ的1.9倍;②突变体和rFⅡ对氧化的胰岛素B链拥有共同的优先裂解位点,可是在随后的裂解中开始展现差异;③突变体显示了更高的纤(原)活性;④热处理表明突变体相较r FⅡ对温度的增加更敏感;⑤通过圆二色谱测量,突变体的螺旋比例有所增加.[结论]删除的序列参与rFⅡ的特异性、活性和热敏感性,该序列可作为下一步优化的候选序列.     

Predictors of oral health quality of life in older adults

There is limited information regarding oral health status and other predictors of oral health‐related quality of life. An association between oral health status and perceived oral health‐related quality of life (OHQOL) might help clinicians motivate patients to prevent oral diseases and improve the outcome of some dental public health programs. This study evaluated the relationship between older persons' OHQOL and their functional dentition, caries, periodontal status, chronic diseases, and some demographic characteristics. A group of 733 low‐income elders (mean age 72.7 ISD=4.71, 55.6% women, 55.1% members of ethnic minority groups in the U.S. and Canada) enrolled in the TEETH clinical trial were interviewed and examined as part of their fifth annual visit for the trial. OHQOL was measured by the Geriatric Oral Health Assessment Index (GOHAI); oral health and occlusal status by clinical exams and the Eichner Index; and demographics via interviews. Elders who completed the four‐year assessment had an average of 21.5 teeth (SD=6.9). with 8.5 occluding pairs (SD=4.6), and 32% with occlusal contacts in all four occluding zones. Stepwise multiple regressions were conducted to predict total GOHAI and its subscores (Physical, Social, and Worry). Functional dentition was a less significant predictor than ethnicity and being foreign‐bom. These variables, together with gender, years since immigrating, number of carious roots, and periodontal status, could predict 32% of the variance in total GOHAI, 24% in Physical, 27% in Social, and 21 % in the Worry subscales. These findings suggest that functional dentition and caries influence older adults' OHQOL, but that ethnicity and immigrant status play a larger role.

Elements of psychological support in nursing care

The paper presents the results of a pilot study which involved 50 nurses from several departments of internal medicine of The State Clinical Hospital of the Collegium Medicum, Jagiellonian University in Cracow. The results are based on the Statement Response Questionnaire. They show that the most common responses of the nurses in the face of anxiety expressed by patients are cheering up the patient, collecting information about the symptom, and offering explanation of the symptom. The least common responses included expressing one's own positive emotions and showing empathy towards the patient.
