Abstract
Practical usability of the majority of current wearable body sensor systems for multiple parameter physiological signal acquisition is limited by the multiple physical connections between sensors and the data-acquisition modules. In order to improve the user comfort and enable the use of these types of systems on active mobile subjects, we propose a wireless body sensor system that incorporates multiple sensors on a single node. This multisensor node includes signal acquisition, processing, and wireless data transmission fitted on multiple layers of a thin flexible substrate with a very small footprint. Considerations for design include size, form factor, reliable body attachment, good signal coupling, low power consumption, and user convenience. The prototype device measures 55 15 mm and is 3 mm thick. The unit is attached to the patient's chest, and is capable of performing simultaneous measurements of parameters, such as body motion, activity intensity, tilt, respiration, cardiac vibration, cardiac potential (ECG), heart rate, and body surface temperature. In this paper, we discuss the architecture of this system, including the multisensor hardware, the firmware, a mobile-phone receiver unit, and assembly of the first proof-of-concept prototype. Preliminary performance results on key elements of the system, such as power consumption, wireless range, algorithm efficiency, ECG signal quality for heart-rate calculations, as well as synchronous ECG and body activity signals are also presented.

Abstract
BACKGROUND To date there is little information on the inflammatory profiles of patients suffering from persistent (PER) and intermittent allergic rhinitis (IAR). Also, it is not clear whether differences exist in eosinophilic inflammation and/or T-helper cell sub-populations and their markers. The aim of this study was to primarily evaluate the inflammatory profiles of patients with moderate/severe PER and IAR. METHODS Inferior nasal turbinate tissue was obtained from 12 PER, 12 IAR and 12 nonallergic nonrhinitic (control) patients, and symptoms (visual analogue scales, VAS) and impairment of life was monitored. All tissues were assessed for eosinophil and mast cell numbers by immunohistochemistry; IL-5, ECP and IgE concentrations by immunoassay; mRNA for transcription factors GATA-3, T-bet, FOXP3 and RORc by quantitative real-time polymerase chain reaction; and IgE-induced release of LTC(4)/D(4)/E(4) and PGD(2)in vitro. RESULTS Eosinophils and mast cells were significantly increased in patients with PER and patients with IAR compared to control subjects; by patients with PER demonstrating even significantly greater increase of both cell types than patients with IAR. Similarly, ECP IL-5, GATA-3 mRNA expression and IgE-induced release of LTC4/D(4)/E(4) and PGD(2) from mast cells were significantly increased in patients with PER compared to patients with IAR. In contrast, the expression of T-bet, FOXP3 or RORc mRNA was not significantly different in the PER, IAR or control patients. CONCLUSION The findings from the present study suggest that PER is characterized by a significantly greater eosinophilic and predominantly Th2 cell-mediated nasal inflammatory profile compared to IAR.

Abstract
The 5-year survival rate in resectable patients with esophageal cancer is only 20% to 36%. Regional relapse and distant metastasis are responsible for the failure of treatment and the majority of cancer-related deaths. Earlier detection of metastases, especially micrometastases, has the potential for more accurate risk stratification in subsequent therapy decisions. No effective techniques have yet been found to detect metastases in erroneously thought to have early stage disease. This study was designed to investigate the clinical significance of bone marrow micrometastases detected by reverse transcriptase-polymerase chain reaction (RT-PCR) in patients with esophageal cancer. Expression of CK19 mRNA in the bone marrow of 61 patients with esophageal squamous cell carcinoma (ESCC) and 15 benign pulmonary and esophageal disease patients was assessed via RT-PCR. Correlation of CK19 mRNA expression to the clinicopathologic features and prognosis of the 61 patients was analyzed: 21.3% (13/61) were positive for expression of CK19 mRNA in patients with ESCC. No CK19 mRNA was detected of the 15 benign pulmonary and esophageal disease patients. CK19 mRNA expression did not correlate with the clinicopathologic features of the patients with ESCC, but patients with CK19 mRNA-positive bone marrow had earlier recurrence and shorter survival after surgery. In multivariate analysis, CK19 mRNA was found to be an independent predictor of a poor outcome. CK19 mRNA may be used as a molecular maker to detect bone marrow micrometastases in patients with ESCC and may help to select the proper therapy and predict the prognosis.

Abstract
Lectins, a class of proteins that reversibly and non-enzymatically bind specific sugars, have been purified from different kinds of legumes. In this study, a 48-kDa lectin (KBL) was purified from Korean large black soybeans using liquid chromatography. The specific hemagglutinating activity of the KBL was 4096 titer/mg. EDTA-induced loss of hemagglutinating activity of KBL could be recovered by addition of Fe(3+) ions and some divalent cations as Ca(2+), Mn(2+), Fe(2+), Cu(2+), Zn(2+), and Pb(2+). Sugars such as D-(+)-galactose, D-(+)-raffinose, L-(+)-arabinose, alpha-D-(+)-melibiose, and alpha-lactose could inhibit the hemagglutinating activity of the lectin. Furthermore, the protein showed high thermal stability as well as stability over a wide range of pH values. KBL inhibited HIV-1 reverse transcriptase activity with an IC(50) of 1.38 microM. However, it was destitute of cytokine releasing, mitogenic, ribonuclease and antifungal activities. In addition, inhibitory activity toward nasopharyngeal cell lines was undetectable in KBL at concentrations up to 20 microM.

Abstract
Aims: To isolate and characterize an antifungal peptide from the seeds of Brassica parachinensis L.H.Bailey. Methods and Results: An antifungal peptide designated as brassiparin was isolated. It exhibited a molecular mass of 5716 Da. It potently inhibited mycelial growth in a number of fungal species including Fusarium oxysporum, Helminthosporium maydis, Mycosphaerella arachidicola and Valsa mali. The antifungal activity of brassiparin toward M. arachidicola exhibited pronounced thermostability and pH stability. It inhibited proliferation of hepatoma (HepG2) and breast cancer (MCF7) cells and the activity of HIV‐1 reverse transcriptase. Its N‐terminal sequence differed from those of antifungal proteins which have been reported to date. Conclusions: Brassiparin can be purified by using a protocol involving ion exchange chromatography, affinity chromatography and gel filtration. It manifests potent, thermostable and pH‐stable antifungal activity. It demonstrates antiproliferative activity toward tumour cells, and inhibitory activity toward HIV‐1 reverse transcriptase. Thus, brassiparin is a defense protein. Significance and Impact of the Study: Brassiparin represents one of the few antifungal proteins reported to date from Brassica species. Its antifungal activity has pronounced pH stability and thermostability. Brassiparin exhibits other exploitable activities such as antiproliferative activity toward hepatoma and breast cancer cells and inhibitory activity toward HIV‐reverse transcriptase.

Abstract
Abstract
Background
Oesophagectomy may have morbidity and mortality rates that severely compromise long-term survival in elderly patients. The aim of this study was to compare clinical outcomes in elderly patients with oesophageal squamous cell carcinoma (SCC) with those of younger controls.
Methods
Elderly patients at least 70 years old with oesophageal SCC were matched 1 : 1 with controls aged less than 70 years according to sex, tumour stage, tumour location, histological grade, surgical approach, completeness of resection and surgical period. Co-morbidities, surgical complications, surgical mortality and long-term survival were compared.
Results
One hundred and thirty-six patients were included in each group. Surgical mortality was greater in the elderly group (5·9 versus 0·7 per cent; P = 0·036). Overall and disease-specific 5-year survival rates were worse among patients aged at least 70 years (30·0 versus 41·8 per cent, and 31·5 versus 44·7 per cent respectively), as were 10-year rates (13·7 versus 26·4 per cent, and 20·2 versus 29·0 per cent). Disease-free survival rates after 5 years (24·0 versus 35·5 per cent) and 10 years (12·3 versus 24·3 per cent) were not statistically significant (P = 0·076).
Conclusion
Poor functional status may account for higher morbidity and mortality rates in elderly patients with oesophageal SCC. Acceptable perioperative mortality rates and substantial long-term survival can still be achieved. Elderly patients should not be denied oesophagectomy.

Abstract
To propose minimal important differences (MID) for the Migraine-Specific Quality of Life Questionnaire version 2.1 (MSQ v2.1). To our knowledge (to date), no published MID values exist for the MSQ v2.1 in any population. Analyses were performed on data from two pivotal clinical trials of topiramate for migraine prevention ( n = 916), as well as from the QualityMetric National Headache Survey ( n = 1016). Analyses included both distribution- and anchor- based MID techniques as well as group- and individual-level MID values. Group-level anchor-based MID values ranged from 3.2 [Role Restrictive domain (RR)] to 7.5 [Emotional Functioning domain (EF)], setting the minimum level of appropriate MID (which can also aid with power analysis). Individual-level distribution-based MID values resulted in highly similar estimates from two large databases: median MID of 8.5 for RR, 9.2 for Role Preventive (RP) and 12.0 for EF. Finally, individual-level anchor-based MID values ranged from 5.0 (RR and RP domains) to 10.6 (EF). For group-level purposes of calculating power for future studies, an MID of 3.2, 4.6 and 7.5 for RR, RP and EF is recommended. For within-group analyses for analysing clinical trial efficacy of each patient's change with responder analyses, 5 points is necessary for RR. For RP and EF, ranges are recommended: 5.0 to 7.9 for RP and 8.0 to 10.6 for EF. These latter two domains tend to have more error in the MID, and thus a sensitivity analysis with both ends of the range should be used to confirm significant differences in responder analyses.

Abstract
OBJECTIVE Bone marrow mesenchymal stem cell (BM-MSC) transplantation has generated a great deal of excitement as a promising therapeutic strategy for diabetes mellitus. However, the exact mechanisms of reversing hyperglycemia remain elusive. Our objective was to investigate whether stem cell differentiation determined therapeutic efficacy. MATERIALS AND METHODS Wistar rats were rendered diabetic by an intraperitoneal injection of streptozotocin. BM-MSCs isolated from diabetic Wistar rats were analyzed for phenotype characteristics. Subsequently, BM-MSCs were transplanted into diabetic rats, followed by intravenous injection of recombinant lentiviruses encoding 2 different small hairpin RNAs (shRNAs) for specific interference with neurogenin 3 (Ngn3). We measured blood glucose levels and insulin and performed histological analysis of the pancreas. RESULTS BM-MSCs lowered blood glucose by increasing beta-cell mass compared with sham-operated controls, but this effect was inhibited by interference with the Ngn3 gene. CONCLUSION Differentiation of stem cells, including BM-MSCs and endogenous pancreatic stem cells, plays a major role in the process of reversing hyperglycemia.

Abstract
In this article, we used a modified ACP system (mACP) developed in our laboratory to analyze differentially expressed genes in the liver of large yellow croaker, Pseudosciaena crocea (Richardson). By using 20 pairs of mACPs, 7 differentially expressed genes were obtained. One of the genes we identified encodes for a fibrinogen beta chain (FGB). The full-length cDNA of FGB was 1645 bp, including 5 bp of 5' untranslated region (5'-UTR), 1479 bp of open reading frame (ORF), and 161 bp of 3'-UTR. The ORF was capable of encoding 492 amino acids with an estimated molecular mass of 55.6 kDa, giving it a predicted pI of 5.94. The deduced amino acid sequence included an FGB profile (V(238)-Y(488)) and an FGB family signature (WWYNRCHSANPNG). Multiple sequence alignments indicated that the large yellow croaker FGB showed homology with FGB sequences of other species (45-77% identity). Real time PCR analysis demonstrated that the expression of FGB in the liver of large yellow croaker injected with Vibrio parahaemolyticus was significantly (P < 0.05) lower than that of the control group at 8 d, which confirmed the expression patterns of the results of mACP differential display.

Abstract
e15562 The optimal management of LAPC remains controversial. The efficacy of CCRT is hampered by early systemic dissemination. To treat undetectable metastases and to select patients who are likely to benefit from CCRT, ICT followed by CCRT has recently been extensively evaluated in LAPC. Recently, we showed that triplet chemotherapy consisting of gemcitabine 800 mg/m2 (10 mg/m2/min) followed by oxaliplatin 85 mg/m2 and 48-hour infusion of 5-FU/LV 3,000 and 150 mg/m2 Q 2 weeks, the GOFL regimen, is feasible and active for pts with APC. Chemo-naïve pts with histo- /cytologically proven unresectable LAPC, and bi-dimensionally measurable diseases were eligible. Patients who did not experience disease progression (PD) after 6 cycles of GOFL would had CCRT consisting of weekly gemcitabine 400mg/m2 plus 50.4Gy/28 fractions of radiation 4–6 weeks later. After CCRT, pts were re-evaluated for surgical intervention and those with unresectable disease would continue GOFL until PD, unacceptable toxicity, patient's refusal or death. Among the 50 enrolled pts (24F/26M, median age 58.5 years), 48 had definitively unresectable diseases. After induction GOFL, 16 (32%) pts were off-studied because of PD in 12 (24%) and ICT-related toxicity in 4 (8%, PD/UE group). Among the 34 (68%) with objective response or stable disease after 6 cycles of ICT, 27 (54%) who completed the assigned multimodality treatment are categorized as CCRT group; whiles 7 (14%) who either declined CCRT (in 5) or still on ICT (in 2) are categorized as non-CCRT group. The median PFS and OS for the ITT population were 9.1 and 14.5 months, respectively. The median PFS for PD/UE, non-CCRT and CCRT groups were 2.1, 8.2 and 12.8 months, respectively; whiles the OS were 8.5, 15.0 and 18.3 months, respectively. The most common grade 3–4 toxicities were neutropenia (40%), anemia (14%), infection (16%), nausea (26%), vomiting (20%). Grade 2–3 peripheral neuropathy was observed in 7 of 29 who received post-CCRT GOFL. Conclusion: Three months of triplet ICT followed by gemcitabine-based CCRT is feasible and likely to prolong the survival of selected LAPC pts. Prospective, randomization study is warranted to validate the findings. No significant financial relationships to disclose.

Abstract
OBJECTIVES HIV disproportionately affects men who have sex with men (MSM), but HIV prevalence among MSM in Guangzhou has not shown the rapid increasing trend as it has elsewhere in China. The aim of this study is to detect the epidemic and to determine the characteristics of MSM in Guangzhou susceptible to HIV. METHODS A cross-sectional survey with serological testing for HIV, syphilis, HBV and HCV through long-chain referral sampling strategy to help control the bias generated from non-statistic sampling. RESULTS The most important features of MSM in Guangzhou are being young and mobile, and of comparable education and income level to that of the general population. The HIV prevalence was 1.3% (95% CI 0.3 to 2.7%) in 2006. Many HIV risk factors were identified: low awareness of HIV risk perception and prevention, high prevalence of diverse, multiple partners and versatile sexual role, more than half of them actively having sex with women, low persistent condom use with both male and female partners, commercial sex and one out of 27 practising needle or syringe sharing during illicit drug use. CONCLUSION HIV has been introduced into MSM in Guangzhou. Demographic and behavioural risk factors and overlapping risk populations contribute to a potentially rapidly rising epidemic among MSM and the potential for a bridge to female partners in Guangzhou if timely and effective interventions are not implemented.

Abstract
Mantle cell lymphoma (MCL) accounts for 5-10% of all non-Hodgkin lymphomas and has the worst prognosis among all lymphomas. The hallmark of MCL is a t(11;14) translocation that results in overexpression of cyclin D1 by tumor cells of virtually all patients. In this study, we examined whether cyclin D1 could be an effective tumor-associated antigen for immunotherapy. We identified cyclin D1 peptides for HLA-A(*)0201 and generated peptide-specific CD8(+) T-cell lines from HLA-A(*)0201(+) blood donors and MCL patients. These cell lines proliferated in response to cyclin D1 peptide-pulsed stimulatory cells. Moreover, the T cells efficiently lysed peptide-pulsed but not unpulsed T2 cells and autologous dendritic cells; cyclin D1(+) and HLA-A(*)0201(+) human MCL lines MINO, SP53, Jeko-1 and Granta 519; and more importantly, HLA-A(*)0201(+) primary lymphoma cells from MCL patients. No killing was observed with HLA-A(*)0201(-) primary lymphoma cells or HLA-A(*)0201(+) normal blood cells, including B cells. These results indicate that these T cells are potent cytotoxic T cells and recognize cyclin D1 peptides naturally presented by patient lymphoma cells in the context of HLA-A(*)0201 molecules. Taken together, our work identifies cyclin D1 as a potentially important antigen for immunotherapy of MCL.

Abstract
BACKGROUND The therapeutic value of mediastinal lymph node dissection (LND) for early-stage non-small cell lung cancer (NSCLC) remains controversial. We conducted a retrospective study to investigate the impact of mediastinal LND on survival in patients with stage I NSCLC. METHODS Clinical data of patients with stage I NSCLC who were treated with surgical resection during a period of ten years were reviewed. The patients were categorized into lobectomy (or pneumonectomy) combined with mediastinal LND or lymph node sampling (LNS) according to the record of their operative procedures. The Kaplan-Meier method was used for survival analysis. Cox proportional hazards model was used for multivariate analysis. RESULTS Of the 319 patients who were included in the study, 139 patients received mediastinal LND, while 180 underwent LNS. There was a significant difference in overall survival (OS) between the group with LND and the group with LNS (5-year survival rate: 76.4 % vs. 65.9 %, P = 0.015 by log rank test). Multivariate analysis showed that lymph node dissection (RR = 0.548, 95 %CI: 0.350 - 0.858, P = 0.009), together with the stage, significantly influenced overall survival. CONCLUSIONS Lobectomy combined with mediastinal LND can improve survival in patients with stage I NSCLC. It should be performed in all patients with clinical stage I NSCLC.

Abstract
BACKGROUND The prothrombinase complex consists of factor Xa, FVa, calcium ions, and phospholipid membrane. The prothrombinase complex plays a key role in the blood coagulation process. OBJECTIVE To derive solvent-equilibrated models of human FVa and the prothrombinase complex. METHODS Several modeling techniques have been employed, including homology modeling, protein-protein docking, and molecular dynamics simulation methods, to build the structural models. RESULTS AND CONCLUSIONS We found, upon simulation, a possibly significant shift towards planarity of the five FVa domains. To estimate a prothrombinase structure, we docked an FXa model to the equilibrated FVa model using experimental data as docking filters. We found that simulation of the docked complex led to some changes in the protein-protein contacts, but not buried surface area, as compared to the initial docking model. Possible locations of prothrombin binding to prothrombinase are indicated.
