BACKGROUND: Etiologic organism is not frequently isolated despite multiple blood and lfuid cultures during management of pyogenic liver abscess (PLA). Such culture negative pyogen-ic liver abscess (CNPLA) is routinely managed by antibiotics targeted toKlebsiella pneumoniae. In this study, we evaluated the outcomes of such clinical practice. METHODS: All the patients with CNPLA andKlebsiella pneu-moniaePLA (KPPLA) admitted from January 2003 to Decem-ber 2011 were included in the study. A retrospective review of medical records was performed and demographic, clinical and outcome data were collected. RESULTS: A total of 528 patients were treated as CNPLA or KPPLA over the study period. CNPLA presented more com-monly with abdominal pain (P=0.024). KPPLA was more com-mon in older age (P=0.029) and was associated with thrombo-cytopenia (P=0.001), elevated creatinine (P=0.002), bilirubin (P=0.001), alanine aminotransferase (P=0.006) and C-reactive protein level (P=0.036). CNPLA patients tend to have anemia (P=0.015) and smaller abscess (P=0.008). There was no differ-ence in hospital stay (15.7 vs 16.8 days) or mortality (14.0% vs 11.0%). No patients required surgical drainage after initiation of medical therapy. CONCLUSION: Despite demographic and clinical differences between CNPLA and KPPLA, overall outcomes are not different.

Cold-inducible RNA-binding protein(CIRP) is a kind of RNA binding proteins that plays important roles in many physiological processes. The CIRP has been widely studied in mammals and amphibians since it was first cloned from mammals. On the contrary, there are little reports in teleosts. In this study, the Po CIRP gene of the Japanese flounder was cloned and sequenced. The genomic sequence consists of seven exons and six introns. The putative Po CIRP protein of flounder was 198 amino acid residues long containing the RNA recognition motif(RRM). Phylogenetic analysis showed that the flounder Po CIRP is highly conserved with other teleost CIRPs. The 5' flanking sequence was cloned by genome walking and many transcription factor binding sites were identified. There is a Cp Gs region located in promoter and exon I region and the methylation state is low. Quantitative real-time PCR analysis uncovered that Po CIRP gene was widely expressed in adult tissues with the highest expression level in the ovary. The m RNA of the Po CIRP was maternally deposited and the expression level of the gene was regulated up during the gastrula and neurula stages. In order to gain the information how the protein interacts with m RNA, we performed the modeling of the 3D structure of the flounder Po CIRP. The results showed a cleft existing the surface of the molecular. Taken together, the results indicate that the CIRP is a multifunctional molecular in teleosts and the findings about the structure provide valuable information for understanding the basis of this protein's function.

A 55-year-old man was admitted for transcatheter closure because of pulmonary arteriovenous fistula by magnetic resonance angiography （MRA）. He had a history of occasional chest pain more than one year. Angiography didn＇t reveal significant stenosis at coronary artery. The patient was found a continuous grade 2/6 murmur over the left upper parastenal area one month ago. Chest MRA revealed a possible left superior pulmonary arteriovenous fistula. For diagnosis and localization of the fistula, aortography and selective angiography of the intemal mammary artery was performed and presented a left internal mammary artery-to-pulmonary artery fistula. The fistula was successfully closed using an 12 mm domestic vascular plug. Chest MRA showed that the fistula disappeared at two-month follow-up

采用冷冻干燥法制备蒙脱土-纳米纤维素(MTM-CNFs)复合基底材料,再通过原位聚合,无模版法构建有序纳米阵列线结构,合成了聚苯胺(PANi)三元复合电极材料。对其微观结构、合成机制、电导率及电化学性质进行了分析,研究了一维线性材料、二维片状材料与导电聚合物的复合机制及无模版法制备PANi阵列储能材料的方法。结果表明,二维MTM纳米片的加入有利于聚苯胺在基底材料上进行原位生长,形成排列有序的阵列线结构,有效提高了电极材料的比电容量。当复合基底材料中MTM和CNFs质量比为1∶9时,合成的PANi/(MTM-CNFs)三元电极材料比电容量最高,达到596 F/g,相比PANi/CNFs二元材料提高了11.5倍。随着基底材料中MTM纳米片的进一步增加和堆叠,活性物质的减少导致材料比电容量的下降,但相比二元材料,仍有明显提高。另外,MTM纳米片的加入有助于稳定复合电极材料的库伦效率,在1000次充放电循环过程中始终保持在100%左右。

现有盾构施工引起地表变形研究中,将土体视为线弹性材料而采用弹性模型来预测地表沉降,具有很大的近似性。引入联合强度理论,分析盾构掘进中、离开后上部土体加荷–卸荷应力状态下的稳定性;通过模拟盾构掘进中、离开后土体的应力路径,开展三轴固结不排水试验,依据试验结果的应力–应变双曲线形态,推导出盾构上部土体竖向加、卸荷条件下的非线性切线弹性模量公式,并确定各参数值。研究结果表明:相同围压或相同固结应力比时,加荷路径土体强度大于卸荷路径土体强度;同一围压下,轴向加荷、卸荷土体破坏时主应力强度值均会随固结应力比增加而增加。预测地表变形时,应力路径法运用了三轴试验成果中轴向应变数据,弹性理论法运用了加、卸荷非线性切线模量及试验参数。以武汉过江隧道江南盾构段为例,应力路径和弹性理论法隆起和沉降量预测值分别相差4.2%和13.0%;两者隆起量预测值与实测值分别相差7.5%和10.7%,沉降量预测值与总沉降实测值趋势一致。
