Abstract
BACKGROUND Radiotherapy is an important strategy for the treatment of advanced gastric cancer (GC), while the radioresistance limits its effectiveness. Nucleolar and spindle associated protein 1 (NUSAP1) was implicated in cancer progression and chemoresistance. However, the underlying mechanisms of NUSAP1 influencing GC radioresistance remain largely unknown. METHODS Meta-analysis was conducted to systematically evaluate the prognostic value of NUSAP1 in human cancers. Gene set enrichment analysis (GSEA) was conducted using The Cancer Genome Atlas (TCGA) and gene expression omnibus (GEO) datasets. MRNA and protein expressions were detected by qRT-PCR and western blot, respectively. The radiosensitivity of GC cells was observed by colony formation, flow cytometry, comet, immunofluorescence, and animal assays. Immunoprecipitation assay and mass spectrometry were utilized to identify protein associations. MiRNAs binding with NUSAP1 were determined by starbase prediction, luciferase reporter, and RNA immunoprecipitation (RIP) assays. RESULTS NUSAP1 high expression predicted worse overall survival (OS) and disease-free survival (DFS) with no statistical heterogeneity through the meta-analysis. Downregulation of NUSAP1 significantly increased GC radiosensitivity by inhibiting colony formation, DNA damage repair, and promoting apoptosis following irradiation. Additionally, NUSAP1 silencing combined with radiation resulted in a synergistic anti-tumor effect in xenograft mouse model. Mechanistically, NUSAP1 interacted with ANXA2, protecting it against protein degradation via impeding its ubiquitination process. NUSAP1 was confirmed as a target of miR-129-5p and negatively regulated by it. CONCLUSION Our results suggested that NUSAP1 enhanced the radioresistance of GC cells. NUSAP1 could be a promising target to increase GC radiosensitivity.

Abstract
BACKGROUND Delayed pressure urticaria (DPU) is characterized by the appearance of typical painful skin lesions (weals) after pressure stimulus. Oral corticosteroids are effective treatments but long-term therapy is problematic. A new topical formulation of clobetasol propionate 0.05% in thermophobic foam (CF) (Olux) has recently become available. The foam is easy to apply, with low skin residues. OBJECTIVES To evaluate in a double-blind placebo-controlled trial the efficacy, tolerability and safety of CF in the topical treatment of DPU. METHODS Twenty-six subjects with a positive history of DPU (13 men, mean age 44 years) were enrolled in a 4-week trial. CF or the corresponding placebo were applied twice daily. Drug application was performed in the most affected areas and in a target area where a standardized pressure challenge test was performed at baseline and at week 4. Efficacy was evaluated by scoring skin lesions regarding erythema, oedema and itching (0, no sign; 4, severe signs) and by calculating the area of the pressure challenge-induced lesion. Safety was evaluated by measuring plasma levels of adrenocorticotropic hormone (ACTH) and cortisol. RESULTS CF significantly (P = 0.0001) reduced lesion area by 84% in comparison with baseline values and by 97% in comparison with the placebo group values. Lesion area in the CF group was reduced from 144 cm(2) to 21 cm(2) at the end of the study. No significant differences in lesion area and clinical lesion scores were observed in the placebo group (lesion area 201 cm(2) at baseline; 216 cm(2) after 4 weeks). A significant clinical improvement was observed in all treated skin areas in the CF group. Mean +/- SD erythema score was reduced by CF from 1.8 +/- 0.6 at baseline to 0.6 +/- 0.5 at the end of the treatment (P = 0.001). Similar modifications were observed also for oedema (from 1.6 +/- 0.6 to 0.2 +/- 0.5) and itching score. Nonsignificant modifications of plasma levels of ACTH, cortisol and glucose were observed in both study groups, in comparison with baseline values. No adverse events were recorded during the trial in either treatment group. CONCLUSIONS CF is effective, safe, convenient and well tolerated in the short-term treatment of DPU.

Abstract
Bullous delayed pressure urticaria (DPU) is a rare variant of DPU. Treatment of DPU is difficult and the underlying pathogenic mechanism of DPU remains elusive. We report a 72-year-old man with DPU and associated chronic urticaria as well as delayed urticarial dermographism. Pressure challenge gave rise to a deep weal covered by multiple vesicles and bullae after 24 h. Histological examination of a skin biopsy specimen obtained 24 h after pressure challenge demonstrated intraepidermal bullae filled with eosinophils accompanied by a dense, predominantly eosinophilic infiltrate in the dermis. Whereas the numbers and morphology of mast cells were unaltered, the extracellular deposition of eosinophil cationic protein revealed evidence for eosinophil activation. Concomitantly, both CD4+ and CD8+ T lymphocytes were present in the infiltrate and expressed interleukin 5. As bullous DPU may represent the maximal variant of DPU, the investigation of the cellular infiltrate and the chemokines/cytokines released may reveal potential pathogenic mechanisms. A possible effector role of eosinophilic granulocytes, T-cell subsets and mast cells is discussed.

Abstract
BACKGROUND Physical urticaria (PU) includes a heterogeneous group of urticarias whose etiopathogenic aspects are still obscure and whose therapeutical management is often difficult. We have previously demonstrated the efficacy of a sequential treatment with nimesulide, a unique nonsteroidal anti-inflammatory drug, and ketotifen in various forms of PU. METHODS The expression of some inflammatory parameters was evaluated in 10 patients affected with some forms of PU. In particular, serum levels of interleukin (IL)-4, IL-1beta, tumor necrosis factor (TNF)-alpha, adhesion molecules (sELAM, sICAM-1 and sVCAM), soluble receptors (sIL-2R, sCD30, sCD23) and IgE were assessed. Moreover, the cutaneous expression of IL-1beta, TNF-alpha and ICAM-1 was studied on biopsy specimens taken from nonlesional skin of patients. The same parameters were further evaluated in both skin and serum following treatment with nimesulide and ketotifen, in order to better understand the possible effects of these agents on the inflammatory network of PU. RESULTS Before therapy we could detect significantly higher serum levels of IL-1beta and TNF-alpha (P < 0.001) and of circulating adhesion molecules in comparison with controls (sELAM, sICAM: P < 0.001; sVCAM: P < 0.02); after treatment, a significant reduction of each was observed (P < 0.05). Simultaneously, a high expression of IL-1beta, TNF-alpha and ICAM-1 was detected in all skin specimens at the baseline, with a relevant decrease following therapy. CONCLUSIONS These results confirm the therapeutical value of treatment with nimesulide and ketotifen in PU and suggest that these agents are able to reduce the release and the expression of some inflammatory molecules that are up-regulated in PU.

Abstract
Neutrophilic urticaria (NU) is a histologically defined entity, but its clinical and pathogenetic aspects are poorly understood. We investigated 22 NU patients whom we identified by examining 118 biopsies of weals. The patients comprised 11 of 20 with acute urticaria, nine of 49 with chronic urticaria, one of 10 with cold urticaria and one of 10 controls undergoing prick tests. Clinically, NU patients had a shorter mean duration of disease than other urticaria patients and significantly increased erythrocyte sedimentation rate and leucocytosis. Histologically, not only neutrophil counts, but to a lesser extent also eosinophil counts and mononuclear cell infiltrates were significantly increased in lesional skin of NU, and there was more marked vasodilatation and endothelial swelling. On immunohistochemistry, increased tumour necrosis factor alpha and interleukin (IL)-3 expression was noted, compared with other urticarias, whereas IL-8 expression was only minor. These data characterize NU as an acute phase urticarial reaction associated with an intense inflammatory infiltrate and marked upregulation of some mast cell-derived cytokines.

Abstract
Urticarial dermographism and delayed pressure urticaria are two forms of physical urticaria which are well defined clinically and histologically. Previous studies have shown eosinophil granule protein deposition in urticarial reactions, including chronic urticaria, solar urticaria and delayed pressure urticaria. To evaluate and compare the involvement of granulated inflammatory cells in urticarial dermographism and delayed pressure urticaria, we studied sequential biopsies of induced lesions of urticarial dermographism and delayed pressure urticaria by indirect immunofluorescence, to detect eosinophil granule major basic protein (MBP) and neutrophil granule elastase. Biopsies from dermographic lesions at time 0, 5 min, 15 min, 2 h and 24 h, showed few infiltrating eosinophils, with minimal extracellular MBP deposition, and a few infiltrating neutrophils, with minimal neutrophil elastase deposition, throughout the evolution of the lesions. Sequential biopsies of delayed pressure urticaria at time 0, 20 min, 6, 12 and 24 h, showed eosinophil infiltration with extensive MBP deposition beginning at 20 min, and neutrophil infiltration with variable elastase deposition beginning at 20 min. Control tissue specimens from normal volunteers showed neutrophil infiltration and slight degranulation, but no eosinophil infiltration or degranulation. Comparison of urticarial dermographism with delayed pressure urticaria showed marked differences in the patterns of infiltration. Delayed pressure urticaria, with eosinophil and neutrophil degranulation, was strikingly similar to the IgE-mediated late phase reaction. In contrast, eosinophil and neutrophil involvement in urticarial dermographism was minimal. Considering the extent of eosinophil granule protein deposition and the biological activities of the eosinophil granule proteins, the findings in delayed pressure urticaria point to an important pathophysiological role of eosinophils in the disease.

Abstract
Six patients with delayed pressure urticaria (DPU) applied clobetasol propionate (0.05%) ointment or its base to predetermined test sites on the right and left thigh as part of a randomized, double-blind study. A pressure challenge was administered to each test site at the initial visit and repeated after 3 days and 6 weeks of treatment and at between 4 and 8 weeks after treatment. The areas of pressure-induced weals were measured 6 h after each challenge. At the 6-week visit, a 4-mm punch biopsy was taken from pressure-challenged skin on each test site. Sections were stained for mast cells and immunohistochemical labelling was used to demonstrate neutrophils (neutrophil elastase), eosinophils (eosinophil cationic protein), monocytes/macrophages (EBM 11), cells expressing the beta-2 integrins (CD11/18) and the vascular adhesion molecules, E selectin and intercellular adhesion molecule-1 (ICAM-1). In the steroid-treated sites, there was a significant decrease (P < 0.05, Wilcoxon's matched-pairs test) in the size of the pressure weals compared with baseline at 3 days, 6 weeks and at follow-up. Demonstrable mast cells were significantly decreased (P = 0.059) in the pressure-challenged areas in the steroid-treated sites compared with the base-treated sites. The histological response to pressure was minimal in both sites perhaps demonstrating an active pharmacological effect of the ointment base. In conclusion, the application of potent topical steroids significantly reduced the clinical response to pressure in patients with DPU, possibly through a reduction in mast cells.

Abstract
We have investigated the kinetics of the leucocyte infiltrate in delayed pressure urticaria (DPU) in relation to the in vivo expression of the cytokine-regulated cell surface adhesion molecules, E-selectin (endothelial adhesion molecule-1, ELAM-1), intercellular adhesion molecule-1 (ICAM-1), and vascular adhesion molecule-1 (VCAM-1). Immunohistochemical analysis was performed on biopsies taken from unchallenged skin, and at 0, 2, 6, 24, 48 and 120 h after weighted rods had been applied to 13 patients with DPU. There was moderate to marked upregulation of E-selectin at 6 and 24 h after application of pressure. At 24 h, more patients showed expression of VCAM-1 on perivascular cells than before pressure. Moderate expression of ICAM-1 was present in some biopsies from both unchallenged and pressure-challenged skin, but there was no clear trend. In DPU, there was a significant increase in the neutrophil count at 2 h after a pressure challenge, with further increases at 6 and 24 h. The median cell counts per high-power field of eosinophils and monocyte/macrophages increased significantly at 24 h after pressure. Biopsies from four normal controls subjected to an identical pressure challenge showed no detectable changes in adhesion molecule expression or in the cell infiltrate. The findings in four patients with chronic idiopathic urticaria not associated with DPU were qualitatively similar to (but intermediate in severity between) the findings in DPU weals at 6 and 24 h. These results suggest that vascular endothelial activation is an early response to pressure challenge in DPU, and is also present in chronic idiopathic urticaria.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Interleukin 1 (IL-1) and interleukin 6 (IL-6) were measured by bioassays in suction-blister exudates from lesional skin, from skin immediately following a pressure challenge, and from control skin (not subjected to pressure) of patients with delayed pressure urticaria. IL-6 activity in lesional exudates was significantly higher than in exudates from the other two sites. IL-1 activity in lesional exudates was not significantly higher than in the control exudates, but significantly less IL-1 activity was found immediately after pressure challenge than from the control site.

Abstract
We report a patient who has an immediate wealing response to pressure in the absence of symptomatic dermographism, which we designate 'immediate-pressure urticaria'. Our patient also suffered from cholinergic urticaria and chronic idiopathic urticaria in the past, demonstrating the clustering of urticarias which frequently occurs.

Abstract
Biopsy specimens from lesional and uninvolved skin of nine patients with delayed pressure urticaria, three patients with acute urticaria, six patients with chronic recurrent urticaria, and four patients with urticaria pigmentosa were analyzed by routine histology and by immunochemistry for their reactivity with monoclonal antibodies to three different subsets of macrophages. Skin from 12 healthy volunteers served as control. Uninvolved skin of patients did not differ from that of healthy volunteers. An antibody against activated macrophages (27E10) was reactive to a marked extent with macrophages in wheals of pressure urticaria, more variably in acute and chronic urticaria, and practically not at all in urticaria pigmentosa. Antibodies with specificities for macrophages in healing (RM3/1) and normal (25F9) tissue reacted more markedly in all but pressure urticaria lesions, compared with normal skin. These findings indicate an active involvement of inflammatory macrophages in whealing reactions while these cells play apparently no role in cutaneous mast cell proliferation (urticaria pigmentosa).

Abstract
The histopathology, immunofluorescence and ultrastructure of skin in idiopathic cold-contact urticaria have been studied over the 24 h following the application of a cold stimulus sufficient to provoke a confluent weal on the anterior thigh. Biopsies were taken 10 min, 2 h and 24 h after ice removal. Considerable epidermal and dermal oedema was present. Type I and Type II mast-cell degranulation was noted but was not universal. Lymphatics and capillaries were dilated and endothelial cells showed an increase in micropinocytotic activity, without evident vasculitis. In two cases packed platelets were seen within vessel lumina. There was no change in the infiltrating dermal cell population and direct immunofluorescence was negative. The evidence suggests that idiopathic cold-contact urticaria is an exudative rather than an infiltrative process.

Abstract
Little is known about the molecular mechanisms or inflammatory mediators involved in delayed pressure urticaria (DPU). Pressure sufficient to provoke lesions was applied to the back of six patients with DPU. The levels of products of arachidonic acid transformation in skin exudate from the pressure challenged skin were estimated immediately after pressure was removed and 6 h later when lesions were present. These were compared to levels estimated in a similar way from unchallenged skin in these patients. Levels of leukotriene C4/D4/E4, prostaglandin E2, 12-hydroxyeicosatetraenoic acid and leukotriene B4 were not raised in lesional skin. Our results suggest that arachidonic acid metabolism is not stimulated in DPU.

Abstract
Multiple sequential biopsy specimens of wheals elicited by a solar simulator in four patients with severe solar urticaria were studied with the use of indirect immunofluorescence for eosinophil granule major basic protein. Examination of control biopsy specimens from normal, unstimulated skin did not show eosinophils or major basic protein deposition. Five minutes after solar simulation, eosinophils were observed in vessels in the dermis, and 2 hours later there was marked tissue eosinophilia. Extracellular major basic protein was extensively deposited in the dermis at 2 and 24 hours, suggesting eosinophil degranulation. Thus evolution of the solar urticaria wheal is accompanied by infiltration of eosinophils and neutrophils and by tissue deposition of the eosinophil major basic protein, suggesting eosinophil degranulation.

Abstract
A randomized double-blind placebo controlled trial of colchicine in the treatment of 13 patients with delayed pressure urticaria enabled us to assess some of the variables in this disorder. We have modified a previously described method of pressure testing using a calibrated dermographometer and shown a pressure induced papular dose response curve. Assessment of disease activity was based on the number of pressure weals which occurred, the size of delayed pressure induced papules using a dermographometer calibrated at 9.75 x 10(5) pascals for five separate time periods on the back and estimations of erythrocyte sedimentation rate and the acute phase protein levels. We have been unable to show a therapeutic effect using colchicine 0.5 mg bd for I week.

Abstract
We studied 44 patients with delayed pressure urticaria. The mean age at onset of the disease was 33 years (range, 5 to 63 years) and the mean duration of disease was 9 years (range, 1 to 40 years). After pressure stimulus, the mean onset of whealing occurred in 3 1/2 hours, the mean peak swelling occurred after 10 hours, and the mean lesion duration was 36 hours. Two thirds of patients had generalized flulike symptoms. Sixty percent had disabling nonremitting delayed pressure urticaria. Sixty-two percent had coexistent chronic idiopathic urticaria, and 27% had angioedema. Delayed pressure urticaria was confirmed by pressure tests with either a calibrated dermographometer or suspended weights. More than 50% of patients tested also had delayed dermographism. A double-blind, controlled, crossover trial of indomethacin therapy in 14 patients revealed no significant subjective improvement or reduction in area of induced wheals. We conclude: (1) The diagnosis of delayed pressure urticaria can be easily made by dermographometer testing. (2) Delayed dermographism may be the same entity as delayed pressure urticaria induced by a different method of pressure application. (3) Systemic corticosteroids remain the only known effective treatment for disabling delayed pressure urticaria.

Abstract
Twenty-three cases of diffuse dermal neutrophilia and urticaria were reviewed. Evidence of vasculitis or other disease was not present. Direct immunofluorescence was done in 19 cases and was positive but nonspecific in 14. The presence of angioedema (10 cases), dermographism (2 cases), atopy (4 cases), drug reactions (6 cases), and infections (6 cases) was similar to that seen in cases of urticaria without diffuse dermal neutrophilia. Nearly 9% of the cases of urticaria show this histologic pattern, and when cases of neutrophilic urticaria are added, 15.8% of cases of urticaria were found to show a major neutrophil component in the inflammation. In urticaria, neutrophilia may be part of an intense stimulus response pattern.

Abstract
Utilizing affinity chromatography-purified antibody to the eosinophil granule major basic protein and formalin-fixed paraffin embedded tissue, we investigated the localization of major basic protein by immunofluorescence in twenty-four skin biopsy specimens from ten patients with pressure urticaria. Fourteen of twenty-four biopsy specimens were obtained from spontaneously occurring urticarial lesions of 4 to 48 hours' duration, and ten of the twenty-four specimens were from dermographometer-induced lesions that had been present from 40 minutes to 24 hours. Twenty-one of twenty-four biopsy specimens showed extracellular fluorescence of eosinophil granule major basic protein within the dermis. The extent and intensity of extracellular staining were not related to the presence or degree of tissue eosinophilia. Serial section controls from each block were stained with protein A purified rabbit IgG and were negative. Previous immunofluorescence studies have demonstrated deposition of major basic protein in lesions of chronic idiopathic urticaria, episodic angioedema, and facial edema. Major basic protein causes release of histamine from human basophils and induces wheal-and-flare reactions on intradermal injection. The present observations add further evidence to support a role for eosinophil mediators, particularly major basic protein, in the pathogenesis of cutaneous disease characterized by edema.
