[PMID: 29783034 DOI: 10.1016/j.jogoh.2018.05.004] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/25/2018] [Revised: 05/14/2018] [Accepted: 05/17/2018] [Indexed: 01/09/2023]
Abstract
We report a case series study on five patients who underwent combined transurethral and transvaginal approaches to repair their vesicovaginal fistulas. All of them had failed the previous surgical treatments for their fistulas. Combined transurethral and transvaginal approaches successfully repaired their vesicovaginal fistulas, with minimal intraoperative bleeding and rapid postoperative recoveries. All the clinical symptoms had resolved. Bladder saline infusion tests and cystogram examinations confirmed the successful closure of their fistulas. Follow-up examinations up to one and a half years showed no return of clinical symptoms. Combined transurethral and transvaginal approaches could be successfully applied to patients who failed previous surgical treatments for the vesicovaginal fistula, when the fistula was smaller than 3cm and was located more than 0.5cm from the ureteral orifice.

Abstract
Background
Hyperglycemia leading to increased oxidative stress is implicated in the increased risk for the development of macrovascular and microvascular complications in patients with type 1 diabetes mellitus.
Methods and Results
A random subcohort of 349 participants was selected from the
DCCT
/
EDIC
(Diabetes Control and Complications Trial/Epidemiology of Diabetes Interventions and Complications) cohort. This included 320 controls and 29 cardiovascular disease cases that were augmented with 98 additional known cases to yield a case cohort of 447 participants (320 controls, 127 cases). Biosamples from
DCCT
baseline, year 1, and closeout of
DCCT
, and 1 to 2 years post‐
DCCT
(
EDIC
years 1 and 2) were measured for markers of oxidative stress, including plasma myeloperoxidase, paraoxonase activity, urinary F
2α
isoprostanes, and its metabolite, 2,3 dinor‐8
iso
prostaglandin F
2α
. Following adjustment for glycated hemoblobin and weighting the observations inversely proportional to the sampling selection probabilities, higher paraoxonase activity, reflective of antioxidant activity, and 2,3 dinor‐8
iso
prostaglandin F
2α
, an oxidative marker, were significantly associated with lower risk of cardiovascular disease (−4.5% risk for 10% higher paraoxonase,
P
<0.003; −5.3% risk for 10% higher 2,3 dinor‐8
iso
prostaglandin F
2α
,
P
=0.0092). In contrast, the oxidative markers myeloperoxidase and F
2α
isoprostanes were not significantly associated with cardiovascular disease after adjustment for glycated hemoblobin. There were no significant differences between
DCCT
intensive and conventional treatment groups in the change in all biomarkers across time segments.
Conclusions
Heightened antioxidant activity (rather than diminished oxidative stress markers) is associated with lower cardiovascular disease risk in type 1 diabetes mellitus, but these biomarkers did not change over time with intensification of glycemic control.

Abstract
BACKGROUND AND AIMS Plasma homocysteine concentrations have been reported to be associated with type 2 diabetes mellitus (T2DM) with controversial findings. The aim of the present study was to investigate the association between plasma homocysteine concentrations and T2DM. METHODS AND RESULTS A cross-sectional study including 19,085 eligible participants derived from the Dongfeng-Tongji cohort was conducted. Plasma homocysteine concentrations were measured by Abbott Architect i2000 Automatic analyzer and T2DM was defined according to American Diabetes Association criteria. Logistic regression model was used to explore the association between plasma homocysteine concentrations and T2DM. The prevalence of T2DM was 19.0% in the whole population (mean age 62.9 years), 21.8% in males, and 17.1% in females. In the multivariable logistic regression analyses, compared with those in the lowest quintile, the OR (95% CI) of T2DM was 1.05 (0.92-1.21), 0.99 (0.86-1.14), 0.90 (0.78-1.05), and 0.77 (0.66-0.90) for quintile 2 to quintile 5 of homocysteine concentrations after adjustment for potential confounders (P for trend < 0.0001). Homocysteine concentrations were associated with decreased T2DM prevalence risk (OR = 0.88 per SD increase of homocysteine concentration; 95% CI: 0.84-0.93). A significant interaction between homocysteine concentrations and drinking status on T2DM prevalence risk was observed (P for interaction = 0.03). The inverse association of plasma homocysteine concentrations with T2DM prevalence risk was observed in non-drinkers but not in current drinkers. CONCLUSION Plasma homocysteine concentrations were inversely correlated with T2DM among a middle-aged and elderly Chinese population.

Abstract
In order to uncover the remarkable pathogenic genes or molecular pathological process in Parkinson's disease (PD), we employed a microarray analysis upon the cellular PD model induced by rotenone. Compared to the control group, 2174 genes were screened out to be expressed differently in the rotenone-induced group by certain criterion. GO analysis and the pathways analysis showed the significant enrichment of genes that were associated with the biological process of cell cycle, apoptotic process, organelle fusion, mitochondrial lesion, endoplasmic reticulum stress and so on. Among these significant DE genes, some were sorted out to be involved in cell cycle and protein processing in endoplasmic reticulum. As the PPI network analysis showed, the interaction relationship of the DEGs involved in the process of protein generation in endoplasmic reticulum(ER) was clearly showed up. As a prediction, we emphasized the genes EDEM1, ATF4, TRAF2 might play central roles in the protein misfolding process during the progression of Parkinson's disease and these new-found genes might be the future research focus and therapeutic targets in PD.

Abstract
OBJECTIVES The impact of electrolyte imbalance on clinical outcomes after acute ischemic stroke (AIS) is still not understood. We investigated the association between hypochloremia and hyponatremia upon hospital admission and in-hospital mortality in AIS patients. MATERIALS AND METHODS A total of 3314 AIS patients enrolled from December 2013 to May 2014 across 22 hospitals in Suzhou city were included in this study. Hypochloremia was defined as having a serum chloride concentration <98 mmol/L and hyponatremia as having a serum sodium concentration <135 mmol/L. The Cox proportional hazard model was used to examine the effect of hypochloremia and hyponatremia on all-cause in-hospital mortality in AIS patients. RESULTS During hospitalization, 118 patients (3.6%) died from all causes. Multivariable model adjusted for age, sex, baseline National Institutes of Health Stroke Scale score, serum sodium, and other potential covariates showed that hypochloremia was associated with a 2.43-fold increase in the risk of in-hospital mortality (hazard ratio [HR] 2.43; 95% confidence interval [CI], 1.41-4.19; P=.001). However, no significant association between hyponatremia (P=.905) and in-hospital mortality was observed. Moreover, the multivariable analysis found that serum chloride (HR=0.92, 95% CI 0.88-0.98; P=.004) but not serum sodium (P=.102) was significantly associated with in-hospital mortality. CONCLUSIONS Hypochloremia at admission was independently associated with in-hospital mortality in AIS patients.

Abstract
Long non-coding RNAs (lncRNAs) are a new research focus that are reported to influence the pathogenetic process of neurodegenerative disorders. To uncover new disease-associated genes and their relevant mechanisms, we carried out a gene microarray analysis based on a Parkinson's disease (PD) in vitro model induced by α-synuclein oligomers. This cellular model induced by 25 μmol/L α-synuclein oligomers has been confirmed to show the stable, transmissible neurotoxicity of α-synuclein, a typical PD pathological marker. And several differentially expressed lncRNAs and mRNAs were identified in this model, such as G046036, G030771, AC009365.4, RPS14P3, CTB-11I22.1, and G007549. Subsequent ceRNA analysis determined the potential relationships between these lncRNAs and their associated mRNAs and microRNAs. The results of the present study widen our horizon of PD susceptibility genes and provide new pathways towards efficient diagnostic biomarkers and therapeutic targets for PD.

Abstract
BACKGROUND AND PURPOSE In clinical practice, stent diameter is one of the variable properties important for endovascular treatment. A consensus guideline for stent retriever size selection has yet to be established. The aim of this study was to investigate the effects of different diameters of Solitaire retrievers on outcomes. MATERIALS AND METHODS Of 628 patients enrolled from the Endovascular Treatment for Acute Anterior Circulation Ischemic Stroke Registry, 256 were treated with the Solitaire 4-mm device and 372, with the 6-mm device. We matched patients treated with the 2 stent sizes using propensity score analysis. The successful outcome was reperfusion as measured by the modified Thrombolysis in Cerebral Infarction score immediately postprocedure and the dichotomized modified Rankin Scale score at 90 days. Symptomatic intracerebral hemorrhage and in-hospital mortality were also recorded. RESULTS After propensity score analysis, group outcomes did not differ. In addition, in patients with atherosclerosis-related occlusion, a higher reperfusion rate (P = .021) was observed in the Solitaire 4 group, as well as a shorter time interval (P = .002) and fewer passes (P = .025). Independent predictors of successful reperfusion in patients with atherosclerotic disease on logistic analysis were the small stent (OR, 3.217; 95% CI, 1.129-9.162; P = .029) and the propensity score acting as a covariate (OR, 52.84; 95% CI, 3.468-805.018; P = .004). CONCLUSIONS We found no evidence of a differential effect of intra-arterial therapy based on the size of Solitaire retrievers. In patients with atherosclerotic disease, favorable reperfusion was associated with deployment of a small stent.

Abstract
The recombinant sTRAIL has been in clinical trial for various human malignancies. However, the half-life time of sTRAIL is very short, which might be an important factor influencing its clinical efficacy for cancer therapy. We previously reported the recombinant adeno-associated virus (AAV)-encoding sTRAIL95-281-mediated sTRAIL expression in vivo up to 8 months and suppressed tumor growth markedly in mouse xenografts. In the present study, we further evaluated the clinical potency for cancer gene therapy and the safety in mouse and non-human primates. The mouse models with HCT-116, NCI-H460 and BEL-7402 cancers were injected intraperitoneally with a single dose of 1.0 × 1011, 1.0 × 1010 and 1.0 × 109 vg of rAAV2-sTRAIL95-281 virus, respectively. The cynomolgus monkeys were injected (i.m.) with a single dose of rAAV2-sTRAIL95-281 of 1 × 1011, 3 × 1011 and 1 × 1012 vg, corresponding to 6-, 20- and 60-fold of intended use dosage for humans, respectively. The efficacy, pharmacology and toxicity of rAAV-sTRAIL in the animals were analyzed accordingly. The tumor inhibitory rates reached 44-76%, 48-52% and 55-74% in the three tumor models, respectively, and they had no influence on mouse spontaneous activity. Administration (s.c.) of a single dose of rAAV2-sTRAIL95-281 virus of 1.0 × 109 or 1.0 × 1010 vg in mice with implanted tumor led to mainly distribution in the spleen, liver, implanted tumor, blood, injected site of muscle and bone marrow. Two weeks later, there was no rAAV2-sTRAIL95-281 detected in blood and bone marrow, and it significantly decreased in other tissues and organs and then gradually cleared away in 4-12 weeks after administration. There was no rAAV2-sTRAIL accumulation in the animal's body and no influence on the body weights. Administration (i.v.) did not cause animal death, and no dose-related abnormal clinical symptoms were found in the mice. There were no abnormal tissue and organ found in all animals. Long-term toxicity test in cynomolgus monkeys did not cause rAAV2-sTRAIL95-281-related toxic and side effects, except that anti-AAV and anti-sTRAIL antibodies were generated. In conclusion, these data demonstrated that administration of rAAV2-sTRAIL95-281 in mice and in cynomolgus monkeys is safe without obvious toxic and side effects to the animals, and throw light on pharmacokinetics and safety in human clinical trials for cancer gene therapy.

Rifampicin pre-treatment inhibits the toxicity of rotenone-induced PC12 cells by enhancing sumoylation modification of α-synuclein. Biochem Biophys Res Commun 2017; 485:23-29. [PMID: 28132806 DOI: 10.1016/j.bbrc.2017.01.100] [Citation(s) in RCA: 16] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/17/2017] [Accepted: 01/19/2017] [Indexed: 11/26/2022]
Abstract
Our previous research revealed that rifampicin could protect PC12 (pheochromocytoma 12) cells from rotenone-induced cytotoxicity by reversing the aggregation of α-synuclein. Furthermore, increasing evidence indicated that the misfolded α-synuclein with SUMOylation, an important protein posttranslational modification, was easier to solubilize and was less toxic. Here, we investigated whether rifampicin could stabilize α-synuclein and prevent rotenone-induced PC12 cells from undergoing apoptosis by enhancing SUMOylation of α-synuclein. The expression of SUMO1 and SUMO2/3, the two main proteins responsible for the SUMOylation modification in PC12 cells, were detected by western blotting. Co-immunoprecipitation was performed to compare qualitatively the SUMOylation modification of α-synuclein. The cell viability and apoptosis rate were measured by a CCK-8 assay kit and flow cytometry, respectively. We targeted Ubc9 as a key enzyme in the SUMOylation modification pathway and knocked down the UBC9 gene using a short interfering RNA. Treatment with 150 μmol/L rifampicin, increased the expressions of SUMO1 and SUMO2/3 in cells by 1.5 times compared with the control group; meanwhile, the cell viability of rotenone-induced cells increased from 20 to 80% (P < 0.05). In addition, the increased SUMOylation activity in the cells stimulated by rifampicin was observed 18 h earlier compared with cells treated by rotenone alone. SUMOylation of α-synuclein was more significant in rifampicin-treated cells and Ubc9 upregulated cells. However, the same phenomenon and the protective effect of rifampicin were reversed after UBC9 knockout. In conclusion, rifampicin might reduce the cytotoxicity of rotenone-induced PC12 cells by promoting SUMOylation of α-synuclein.

Abstract
PURPOSE The aim of this study was to compare the organ-at-risk doses to the rectum and the bladder in postoperative endometrial cancer patients who receive high-dose-rate vaginal brachytherapy (HDR-VB), when using three different methods of treatment planning: (Workflow A) individualized treatment planning before every fraction, (Workflow B) individualized treatment planning for first fraction only), and (Workflow C) using a template plan based on applicator choice and prescription specifics without patient-specific imaging or planning (standardized template approach). METHODS AND MATERIALS Alternative plans were retrospectively created using workflows B and C for 22 patients who previously received postoperative HDR-VB using a vaginal cylinder and planned using Workflow A for endometrial cancer. The rectum and bladder were contoured on the CTs used for each fraction for dose comparison between the three methods. D50, D2cc, D1cc, D0.1cc, and V100 of the bladder and the rectum were compared using the two-sided Wilcoxon signed-rank test. RESULTS A total of 123 fractions were available for comparison. For Workflow A vs. Workflow B, there was no significant difference for any rectal or bladder dosimetric parameter. For Workflow A vs. Workflow C, Workflow A delivered a significantly higher median dose to the rectum than Workflow C for D50, D2cc, D1cc, and V100. Workflow C delivered a significantly higher dose to the bladder than Workflow A: D2cc, D1cc, D0.1cc, and V100. However, the magnitudes of the differences were small; the dose index difference was >75 cGy for only two fractions. CONCLUSION Plan standardization in HDR-VB may result in considerable time and cost savings with minimal organ-at-risk dose differences.

Abstract
The nuclear factor of activated T cells (NFAT) family proteins are transcription factors that regulate the expression of pro-inflammatory cytokines and other genes during the immune response. Although the NFAT proteins have been extensively investigated in the immune system, their role in cancer progression remains controversial. Here, we report that NFAT3 is highly expressed in various skin cancer cell lines and tumor tissues. Knockdown of endogenous NFAT3 expression by short hairpin RNA (shRNA) significantly inhibited tumor cell proliferation, colony formation and anchorage-independent cell growth. Furthermore, results of the mammalian two-hybrid assay showed that cyclin-dependent kinase 3 (CDK3) directly interacted with NFAT3 and phosphorylated NFAT3 at serine 259 (Ser259), which enhanced the transactivation and transcriptional activity of NFAT3. The phosphorylation site of NFAT3 was critical for epidermal growth factor (EGF)-stimulated cell transformation of the HaCaT immortalized skin cell line and mutation of NFAT3 at Ser259 led to a reduction of colony formation in soft agar. We also found that overexpressing wildtype NFAT3, but not mutant NFAT3-S259A, promoted A431 xenograft tumor growth. Importantly, we showed that CDK3, NFAT3 and phosphorylated NFAT3-Ser259 were highly expressed in skin cancer compared with normal skin tissues. These results provided evidence supporting the oncogenic potential of NFAT3 and suggested that CDK3-mediated phosphorylation of NFAT3 has an important role in skin tumorigenesis.

Abstract
In this paper modeling and common-rail pressure control of high pressure common rail injection system (HPCRIS) is presented. The proposed mathematical model of high pressure common rail injection system which contains three sub-systems: high pressure pump sub-model, common rail sub-model and injector sub-model is a relative complicated nonlinear system. The mathematical model is validated by the software Matlab and a virtual detailed simulation environment. For the considered HPCRIS, an effective model free controller which is called Extended State Observer - based intelligent Proportional Integral (ESO-based iPI) controller is designed. And this proposed method is composed mainly of the referred ESO observer, and a time delay estimation based iPI controller. Finally, to demonstrate the performances of the proposed controller, the proposed ESO-based iPI controller is compared with a conventional PID controller and ADRC.

Abstract
OBJECTIVES To explore the serum levels of bone resorption marker C-terminal telopeptide of type I collagen (CTX) and bone formation marker N-amino terminal propeptide of type I collagen (PINP) in Chinese women across the menopausal transition and the correlation between follicle stimulating hormone (FSH), luteinizing hormone (LH) and estradiol with the bone turnover markers. METHODS A cross-sectional study was conducted on 464 healthy Chinese women, separated into pre-, peri- and postmenopausal groups based on their menstruation changes. The serum levels of CTX, PINP, FSH, LH, and estradiol were measured. RESULTS The serum levels of CTX and PINP were significantly higher in women in the peri- and postmenopausal groups. The serum levels of FSH were significantly correlated with the serum levels of PINP in premenopausal women. Both serum FSH and LH were positively correlated with serum CTX in perimenopausal women and postmenopausal women. Estradiol was inversely correlated with CTX in the perimenopausal group. Multiple linear regression models show the serum FSH levels were independently related to the bone turnover markers CTX and PINP. CONCLUSIONS The elevated serum levels of FSH were independent risk factors for bone loss in peri- and postmenopausal women, and measurement of the serum FSH levels in mid-age women with irregular menses could be used in early diagnosis of postmenopausal osteoporosis.

Abstract
Molecular monitoring of chronic myeloid leukemia patients using robust BCR-ABL1 tests standardized to the International Scale (IS) is key to proper disease management, especially when treatment cessation is considered. Most laboratories currently use a time-consuming sample exchange process with reference laboratories for IS calibration. A World Health Organization (WHO) BCR-ABL1 reference panel was developed (MR1–MR4), but access to the material is limited. In this study, we describe the development of the first cell-based secondary reference panel that is traceable to and faithfully replicates the WHO panel, with an additional MR4.5 level. The secondary panel was calibrated to IS using digital PCR with ABL1, BCR and GUSB as reference genes and evaluated by 44 laboratories worldwide. Interestingly, we found that >40% of BCR-ABL1 assays showed signs of inadequate optimization such as poor linearity and suboptimal PCR efficiency. Nonetheless, when optimized sample inputs were used, >60% demonstrated satisfactory IS accuracy, precision and/or MR4.5 sensitivity, and 58% obtained IS conversion factors from the secondary reference concordant with their current values. Correlation analysis indicated no significant alterations in %BCR-ABL1 results caused by different assay configurations. More assays achieved good precision and/or sensitivity than IS accuracy, indicating the need for better IS calibration mechanisms.

Abstract
BACKGROUND AND PURPOSE Diffusion tensor imaging may reflect pathology of the optic nerve; however, the ability of DTI to evaluate alterations of the optic nerve in retinitis pigmentosa has not yet been assessed, to our knowledge. The aim of this study was to investigate the diagnostic potential of reduced FOV-DTI in optic neuropathy of retinitis pigmentosa at 3T. MATERIALS AND METHODS Thirty-eight patients and thirty-five healthy controls were enrolled in this study. Measures of visual field and visual acuity of both eyes in all subjects were performed. A reduced FOV-DTI sequence was used to derive fractional anisotropy, apparent diffusion coefficient, principal eigenvalue, and orthogonal eigenvalue of the individual optic nerves. Mean fractional anisotropy, ADC, and eigenvalue maps were obtained for quantitative analysis. Further analyses were performed to determine the correlation of fractional anisotropy, ADC, principal eigenvalue, and orthogonal eigenvalue with optic nerves in patients with mean deviation of the visual field and visual acuity, respectively. RESULTS The optic nerves of patients with retinitis pigmentosa compared with control subjects showed significantly higher ADC, principal eigenvalue, and orthogonal eigenvalue and significantly lower fractional anisotropy (P < .01). For patients with retinitis pigmentosa, the mean deviation of the visual field of the optic nerve was significantly correlated with mean fractional anisotropy (r = 0.364, P = .001) and orthogonal eigenvalue (r = -0.254, P = .029), but it was not correlated with mean ADC (P = .154) and principal eigenvalue (P = .337). Moreover, no correlation between any DTI parameter and visual acuity in patients with retinitis pigmentosa was observed (P > .05). CONCLUSIONS Reduced FOV-DTI measurement of the optic nerve may serve as a biomarker of axonal and myelin damage in optic neuropathy for patients with retinitis pigmentosa.

Abstract
The present study screened potential genes related to lung adenocarcinoma, with the
aim of further understanding disease pathogenesis. The GSE2514 dataset including 20
lung adenocarcinoma and 19 adjacent normal tissue samples from 10 patients with lung
adenocarcinoma aged 45-73 years was downloaded from Gene Expression Omnibus.
Differentially expressed genes (DEGs) between the two groups were screened using the
t-test. Potential gene functions were predicted using functional
and pathway enrichment analysis, and protein-protein interaction (PPI) networks
obtained from the STRING database were constructed with Cytoscape. Module analysis of
PPI networks was performed through MCODE in Cytoscape. In total, 535 upregulated and
465 downregulated DEGs were identified. These included ATP5D,
UQCRC2, UQCR11 and genes encoding nicotinamide
adenine dinucleotide (NADH), which are mainly associated with mitochondrial ATP
synthesis coupled electron transport, and which were enriched in the oxidative
phosphorylation pathway. Other DEGs were associated with DNA replication
(PRIM1, MCM3, and RNASEH2A),
cell surface receptor-linked signal transduction and the enzyme-linked receptor
protein signaling pathway (MAPK1, STAT3,
RAF1, and JAK1), and regulation of the
cytoskeleton and phosphatidylinositol signaling system (PIP5K1B,
PIP5K1C, and PIP4K2B). Our findings suggest that
DEGs encoding subunits of NADH, PRIM1, MCM3, MAPK1, STAT3, RAF1, and JAK1 might be
associated with the development of lung adenocarcinoma.

Radiobiological impact of dose calculation algorithms on biologically optimized IMRT lung stereotactic body radiation therapy plans. Radiat Oncol 2016; 11:10. [PMID: 26800883 PMCID: PMC4724090 DOI: 10.1186/s13014-015-0578-2] [Citation(s) in RCA: 20] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/15/2015] [Accepted: 12/22/2015] [Indexed: 12/25/2022] Open
Abstract
Background The aim of this study is to evaluate the radiobiological impact of Acuros XB (AXB) vs. Anisotropic Analytic Algorithm (AAA) dose calculation algorithms in combined dose-volume and biological optimized IMRT plans of SBRT treatments for non-small-cell lung cancer (NSCLC) patients. Methods Twenty eight patients with NSCLC previously treated SBRT were re-planned using Varian Eclipse (V11) with combined dose-volume and biological optimization IMRT sliding window technique. The total dose prescribed to the PTV was 60 Gy with 12 Gy per fraction. The plans were initially optimized using AAA algorithm, and then were recomputed using AXB using the same MUs and MLC files to compare with the dose distribution of the original plans and assess the radiobiological as well as dosimetric impact of the two different dose algorithms. The Poisson Linear-Quadatric (PLQ) and Lyman-Kutcher-Burman (LKB) models were used for estimating the tumor control probability (TCP) and normal tissue complication probability (NTCP), respectively. The influence of the model parameter uncertainties on the TCP differences and the NTCP differences between AAA and AXB plans were studied by applying different sets of published model parameters. Patients were grouped into peripheral and centrally-located tumors to evaluate the impact of tumor location. Results PTV dose was lower in the re-calculated AXB plans, as compared to AAA plans. The median differences of PTV(D95%) were 1.7 Gy (range: 0.3, 6.5 Gy) and 1.0 Gy (range: 0.6, 4.4 Gy) for peripheral tumors and centrally-located tumors, respectively. The median differences of PTV(mean) were 0.4 Gy (range: 0.0, 1.9 Gy) and 0.9 Gy (range: 0.0, 4.3 Gy) for peripheral tumors and centrally-located tumors, respectively. TCP was also found lower in AXB-recalculated plans compared with the AAA plans. The median (range) of the TCP differences for 30 month local control were 1.6 % (0.3 %, 5.8 %) for peripheral tumors and 1.3 % (0.5 %, 3.4 %) for centrally located tumors. The lower TCP is associated with the lower PTV coverage in AXB-recalculated plans. No obvious trend was observed between the calculation-resulted TCP differences and tumor size or location. AAA and AXB yield very similar NTCP on lung pneumonitis according to the LKB model estimation in the present study. Conclusion AAA apparently overestimates the PTV dose; the magnitude of resulting difference in calculated TCP was up to 5.8 % in our study. AAA and AXB yield very similar NTCP on lung pneumonitis based on the LKB model parameter sets we used in the present study.

Abstract
PUVA-SP DCs are immature dendritic cells (imDCs) that have taken up donor splenic lymphocytes treated with 8-methoxypsoralen and ultraviolet A light (PUVA-SPs). Phagocytosis of donor PUVA-SPs does not stimulate phenotype maturation of recipient imDCs, and infusion of PUVA-SP DCs can induce CD4(+)CD25(high)Foxp3(+) regulatory T cells (Treg). However, the regulatory effect of PUVA-SP DCs on B cells is poorly understood. In this study, we compared PUVA-SP DCs with imDCs in terms of lipopolysaccharide (LPS) responsiveness and flow cytometric analysis of interleukin (IL) 10 expression in splenic CD19(+)B cells. Our results demonstrate that PUVA-SP DCs can suppress subsequent LPS-induced DC maturation and that infusion of PUVA-SP DCs, in the absence of an immunosuppressant, significantly promotes skin allograft survival. This effect was associated with up-regulation of circulating regulatory B cells exhibiting preferential IL-10 secretion. Our results suggest that effective treatments involving infusion of PUVA-SP DCs is likely related to the modulation not only of T-cell and Treg functions but also of B-cell and regulatory B-cell (Breg) functions.

Abstract
The outer membrane protein RagB is one of the major virulence factors of Porphyromonas gingivalis (P. gingivalis). To prevent periodontitis and associated systemic diseases induced by P. gingivalis, we built B cell antigen epitope vaccine characterized by pIRES-ragB'-mGITRL to induce a protective immune responses. The B cell antigen epitope and scrambled peptide of ragB were predicted, cloned into pIRES and constructed pIRES-ragB', pIRES-scrambled epitopes and pIRES-ragB'-mGITRL. pIRES-ragB'-mGITRL was transfected into COS-7 cells. Subsequently, the 6-week-old female BALB/c mice were challenged by P. gingivalis following three time immunization by pIRES, pIRES-ragB', pIRES-scrambled epitopes and pIRES-ragB'-mGITRL. The levels of RagB-specific antibody in the serum and Tfh cells in the spleen were measured by ELISA and flow cytometry, respectively. And higher levels of RagB-specific IgG were produced in the immunized mice with pIRES-ragB'-mGITRL. Additionally, the number of Tfh cells was also expanded and lesions were diminished in pIRES-ragB'-mGITRL mice comparing with control groups. Our results clearly demonstrated that P. gingivalis B cell antigen epitope vaccine, pIRES-ragB'-mGITRL, could induce protective immune responses. Furthermore, our data also indicated that pIRES-ragB'-mGITRL was a potential therapeutic vaccine against P. gingivalis.
