Abstract
BACKGROUND/AIMS We sought to identify the most relevant hemofilter for cytokine removal based on the mechanisms of filtration and adsorption. METHODS Ascites were filtered using four types of hemofilters composed of different membrane materials (polymethyl methacrylate, PMMA, cellulose triacetate, CTA, or polysulfone, PS) and different surface areas (1.0 or 2.1 m(2)) to investigate the rate of interleukin-6 (IL-6) filtration. Next, ascites were perfused through each hemofilter without obtaining a filtrate to study each filter's adsorptive capability. RESULTS The PMMA hemofilters resulted in a marginal observed IL-6 filtration rates, whereas the CTA and PS hemofilters resulted in highly effective IL-6 filtration. Regarding the IL-6 adsorptive capabilities of the filters, the PMMA hemofilter with a large surface area showed the highest level of IL-6 clearance. CONCLUSION The present findings suggest that when cytokine removal based on filtration is desired, CTA or PS hemofilters should be selected. When IL-6 removal based on adsorption is desired, a PMMA hemofilter with a large surface area should be selected.

Abstract
INTRODUCTION Bacteremia is recognized as a critical condition that influences the outcome of sepsis. Although large-scale surveillance studies of bacterial species causing bacteremia have been published, the pathophysiological differences in bacteremias with different causative bacterial species remain unclear. The objective of the present study is to investigate the differences in pathophysiology and the clinical course of bacteremia caused by different bacterial species. METHODS We reviewed the medical records of all consecutive patients admitted to the general intensive care unit (ICU) of a university teaching hospital during the eight-year period since introduction of a rapid assay for interleukin (IL)-6 blood level to routine ICU practice in May 2000. White blood cell count, C-reactive protein (CRP), IL-6 blood level, and clinical course were compared among different pathogenic bacterial species. RESULTS The 259 eligible patients, as well as 515 eligible culture-positive blood samples collected from them, were included in this study. CRP, IL-6 blood level, and mortality were significantly higher in the septic shock group (n = 57) than in the sepsis group (n = 127) (P < 0.001). The 515 eligible culture-positive blood samples harbored a total of 593 isolates of microorganisms (Gram-positive, 407; Gram-negative, 176; fungi, 10). The incidence of Gram-negative bacteremia was significantly higher in the septic shock group than in the sepsis group (P < 0.001) and in the severe sepsis group (n = 75, P < 0.01). CRP and IL-6 blood level were significantly higher in Gram-negative bacteremia (n = 176) than in Gram-positive bacteremia (n = 407) (P < 0.001, <0.0005, respectively). CONCLUSIONS The incidence of Gram-negative bacteremia was significantly higher in bacteremic ICU patients with septic shock than in those with sepsis or severe sepsis. Furthermore, CRP and IL-6 levels were significantly higher in Gram-negative bacteremia than in Gram-positive bacteremia. These findings suggest that differences in host responses and virulence mechanisms of different pathogenic microorganisms should be considered in treatment of bacteremic patients, and that new countermeasures beyond conventional antimicrobial medications are urgently needed.

Abstract
INTRODUCTION Neurological prognostic factors after cardiopulmonary resuscitation (CPR) in patients with cardiac arrest (CA) as early and accurately as possible are urgently needed to determine therapeutic strategies after successful CPR. In particular, serum levels of protein neuron-specific enolase (NSE) and S-100B are considered promising candidates for neurological predictors, and many investigations on the clinical usefulness of these markers have been published. However, the design adopted varied from study to study, making a systematic literature review extremely difficult. The present review focuses on the following three respects for the study design: definitions of outcome, value of specificity and time points of blood sampling. METHODS A Medline search of literature published before August 2008 was performed using the following search terms: "NSE vs CA or CPR", "S100 vs CA or CPR". Publications examining the clinical usefulness of NSE or S-100B as a prognostic predictor in two outcome groups were reviewed. All publications met with inclusion criteria were classified into three groups with respect to the definitions of outcome; "dead or alive", "regained consciousness or remained comatose", and "return to independent daily life or not". The significance of differences between two outcome groups, cutoff values and predictive accuracy on each time points of blood sampling were investigated. RESULTS A total of 54 papers were retrieved by the initial text search, and 24 were finally selected. In the three classified groups, most of the studies showed the significance of differences and concluded these biomarkers were useful for neurological predictor. However, in view of blood sampling points, the significance was not always detected. Nevertheless, only five studies involved uniform application of a blood sampling schedule with sampling intervals specified based on a set starting point. Specificity was not always set to 100%, therefore it is difficult to indiscriminately assess the cut-off values and its predictive accuracy of these biomarkers in this meta analysis. CONCLUSIONS In such circumstances, the findings of the present study should aid future investigators in examining the clinical usefulness of these markers and determination of cut-off values.

Abstract
OBJECTIVE To examine the role of hypercytokinemia in the pathophysiology of tumor lysis syndrome (TLS) and the efficacy of continuous hemodiafiltration in the treatment of TLS. DESIGN AND SETTING Retrospective observational study in a general intensive care unit of a university hospital. PATIENTS Four patients with hematological disorder developing TLS after the treatment of anti-tumor chemotherapy. INTERVENTIONS Continuous hemodiafiltration using a polymethylmethacrylate membrane hemofilter (PMMA-CHDF) was performed at the onset of TLS. Blood samples were collected daily after ICU admission, and clinical parameters and blood levels of cytokines were evaluated. MEASUREMENTS AND RESULTS All four patients underwent induction anti-tumor chemotherapy, during which they developed hyperuricemia, hyperkalemia, and acute renal failure. Two of them also developed multiple organ failure. Serum levels of tumor necrosis factor (TNF) -alpha, interleukin-6 (IL-6), and IL-10 prior to the initiation of PMMA-CHDF were 102+/-85 pg/mL, 1097+/-546 pg/mL, and 98+/-83 pg/mL, respectively (mean +/- SD). After three days of PMMA-CHDF treatment, corresponding blood levels were 37+/-55 pg/mL, 326+/-511pg/mL, and 9+/-8 pg/mL, respectively. Thus, all cytokine levels were significantly decreased by three days of PMMA-CHDF treatment (p<0.05, paired t-test). Following three days of PMMA-CHDF treatment, blood urea nitrogen (BUN) and serum creatinine (Cre.) were significantly decreased (pre/post BUN 42.3+/-15.4/16.5+/-8.4 mg/dL, p<0.05, pre/post Cre. 2.7+/-1.2/1.2+/-0.6 mg/dL, mean +/- SD, p<0.05). Furthermore, the clinical condition of each patient was improved after the treatment of PMMA-CHDF, and all of four patients were survived. CONCLUSION Hypercytokinemia plays a pivotal role in the pathophysiology of TLS and PMMA-CHDF may be an effective therapeutic modality for TLS patients not only as renal replacement therapy but also as a cytokine modulator.

Abstract
Anti-p200 pemphigoid is a recently described autoimmune blistering skin disease that is characterized by the presence of autoantibodies against an unidentified 200-kDa dermal autoantigen. Most of the previous cases have been successfully treated using mild-to-moderate immunosuppressive therapies, which resulted in a good prognosis. We report here a severe and refractory case of anti-p200 pemphigoid that developed in a 53-year-old woman, in which blisters led to multiple skin ulcers, followed by severe scar formation. In the present case, methylprednisolone pulse therapy was effective enough to reduce the disease activity.

Abstract
The clinical effects and tolerability of micafungin sodium in daily practice for the treatment of fungal infection in critically ill patients were evaluated in an open-labeled, non-comparative, observational study. All patients admitted to intensive care units (ICUs) of 3 hospitals in Chiba prefecture between June 2003 and March 2005, who were treated with micafungin because of known or suspected fungal infection, were included in the study. A total of 34 patients received micafungin and 29 cases of them were subjected to analysis. Fungal infections were classified as "proven" in 3 patients (10.3%) and "possible" in 26 (89.7%). Candida was detected in 16 patients, most of them were Candida albicans and 4 cases were non-albicans Candida. Clinical effects of micafungin were "cured" and "improved" in 20 patients (77%), "failure" in 6 (23%), and "undetermined" in 3 cases. Adverse events were reported in 10 patients, but there was no significant event. In conclusion, micafungin was effective in 77% of proven or suspected fungal infections in critically ill patients admitted to the ICU. The drug was well tolerated and discontinuation of its treatment due to adverse events was not experienced during the study period.

Abstract
Oral lichen planus (LP) is a severe, painful form of LP, and is often resistant to topical corticosteroid therapy. Recently, open trials demonstrated that topical tacrolimus therapy was effective for the treatment of chronic erosive oral LP. We report two cases with severe recalcitrant erosive oral LP, who dramatically benefited from topical tacrolimus therapy. In case 1, a 64-year-old man presented with a 5-month history of painful erosions on his entire lower lip and buccal mucosa. Physical and histological examination confirmed a diagnosis of LP. He experienced rapid relief from pain and a dramatic improvement was obtained within 5 weeks of topical tacrolimus treatment. No significant irritation was observed and blood tacrolimus level was kept within a safe level (2.5 ng/mL). In case 2, a 68-year-old man developed painful erosions on his right lower lip and buccal mucosa 2 months before his arrival at our hospital. Histopathological analysis confirmed a diagnosis of oral LP. He experienced a rapid dramatic improvement of both lesions within 4 weeks of the start of tacrolimus application. No significant irritation or recurrence was observed. Thus, topical tacrolimus is suggested as a well-tolerated, effective therapy for oral LP.

Abstract
The normal heart rate is regulated by a number of interacting physiological control systems that operate on widely different time scales. Thus, instantaneous heart rate is not steady, but rather demonstrates continuous fluctuations. It has been recognized that power spectral analysis of heart rate variability (HRV) is a noninvasive method to assess cardiac autonomic modulation. We hypothesized that the loss of interconnectivity or coupling between heart and other organs results in the occurrence of septic shock in patients with severe sepsis. We found that the reduction of HRV precedes the occurrence of septic shock. Therefore, we conclude that analysis of HRV is a novel and useful tool to predict the occurrence of septic shock among the patients with severe sepsis.

Abstract
The genetic diversity of populations of the azuki bean beetle, Callosobruchus chinensis (Linnaeus) from natural, pre-harvest and post-harvest sites, was investigated to understand population structure and gene flow. A 522-bp fragment of the mitochondrial gene COI was sequenced for eight populations of C. chinensisfrom Japan, Korea and Taiwan collected from different habitats. Six haplotypes were detected, one of which, U1, occurred most frequently and widely. The following hypotheses were tested as a cause of the wide distribution of haplotype U1; (i) topographical separation (by national boundaries), (ii) host plant species, and (iii) habitat type (natural, pre-harvest crop, or post-harvest storage). Categorization of collection sites by country or by host species did not yield differences in the occurrence of haplotype U1, but habitat type did. Populations utilizing cultivated post-harvest hosts that were mass stored were highly likely to be the common haplotype, whereas host plants in natural habitats away from agriculture were utilized by populations with locally characteristic haplotypes. Sampling of commercial beans for quarantine and export purposes indicated that gene flow in C. chinensis was largely unidirectional into Japan at the present time.

Abstract
We examined the role of chemokine signaling on the lymph node metastasis of oral squamous cell carcinoma (SCC) using lymph node metastatic (HNt and B88) and nonmetastatic oral SCC cells. Of 13 kinds of chemokine receptors examined, only CXCR4 expression was up-regulated in HNt and B88 cells. CXCR4 ligand, stromal-cell-derived factor-1alpha (SDF-1alpha; CXCL12), induced characteristic calcium fluxes and chemotaxis only in CXCR4-expressing cells. CXCR4 expression in metastatic cancer tissue was significantly higher than that in nonmetastatic cancer tissue or normal gingiva. Although SDF-1alpha was undetectable in either oral SCC or normal epithelial cells, submandibular lymph nodes expressed the SDF-1alpha protein, mainly in the stromal cells, but occasionally in metastatic cancer cells. The conditioned medium from lymphatic stromal cells promoted the chemotaxis of B88 cells, which was blocked by the CXCR4 neutralization. SDF-1alpha rapidly activated extracellular signal-regulated kinase (ERK)1/2 and Akt/protein kinase B (PKB), and their synthetic inhibitors attenuated the chemotaxis by SDF-1alpha. SDF-1alpha also activated Src family kinases (SFKs), and its inhibitor PP1 diminished the SDF-1alpha-induced chemotaxis and activation of both ERK1/2 and Akt/PKB. These results indicate that SDF-1/CXCR4 signaling may be involved in the establishment of lymph node metastasis in oral SCC via activation of both ERK1/2 and Akt/PKB induced by SFKs.

Abstract
TSC-22 gene was composed of three exons and its length was approximately 5.5 kb including 2.9 kb promoter region. The transcription starting site was located at 7 and 29 bp downstream from TATA box. Promoter analysis revealed that 2146 bp of TSC-22 promoter was activated by several differentiation inducing drugs. Although originally TSC-22 was isolated as a TGF-beta-inducible gene, TSC-22 promoter was not activated by the enhanced TGF-beta signaling. We found 3 copies of the Shaw-Kamens sequence (AUUUA) in the human TSC-22 mRNA 3'-UTR and identified three proteins (40, 20, and 15 kDa) which bound to this. Only the 40 kDa protein-RNA complex was decreased by treatment with TGF-beta 1. Moreover, the TSC-22 mRNA 3'-UTR destabilized the heterologous luciferase mRNA, but the destabilization was recovered with TGF-beta 1. These observations suggest that up-regulation of TSC-22 mRNA by TGF-beta 1 is achieved by mRNA stabilization, but not by transcriptional activation.

Abstract
Werner syndrome (WS) is caused by mutations in the gene encoding RecQ type DNA helicase (WRN). We report a 53-year-old Japanese male with WS who initially presented with skin ulcers on the feet and the left elbow. The patient had a high-pitched voice, hoarseness, a characteristic bird-like facial appearance with a beak-shaped nose, canities and juvenile cataracts. Immunoblot analysis using a monoclonal antibody directed against the WS gene product DNA helicase revealed that the patient's leucocytes lacked this particular molecule, confirming the diagnosis of WS. This new immunoblot system therefore enables the diagnosis of WS to be made without the need to undertake more complex mutational analysis.
