Abstract
Allergic rhinitis (AR) is a systemic allergic disease that has a considerable impact on patients' quality of life. Current treatments include antihistamines and nasal steroids; however, their long-term use often causes undesirable side effects. In this context, traditional Asian medicine (TAM), with its multi-compound, multi-target herbal medicines (medicinal plants), offers a promising alternative. However, the complexity of these multi-compound traits poses challenges in understanding the overall mechanisms and efficacy of herbal medicines. Here, we demonstrate the efficacy and underlying mechanisms of these multi-compound herbal medicines specifically used for AR at a systemic level. We utilized a modified term frequency-inverse document frequency method to select AR-specific herbs and constructed an herb-compound-target network using reliable databases and computational methods, such as the Quantitative Estimate of Drug-likeness for compound filtering, STITCH database for compound-target interaction prediction (with a high confidence score threshold of 0.7), and DisGeNET and CTD databases for disease-gene association analysis. Through this network, we conducted AR-related targets and pathway analyses, as well as clustering analysis based on target-level information of the herbs. Gene ontology enrichment analysis was conducted using a protein-protein interaction network. Our research identified 14 AR-specific herbs and analyzed whether AR-specific herbs are highly related to previously known AR-related genes and pathways. AR-specific herbs were found to target several genes related to inflammation and AR pathogenesis, such as PTGS2, HRH1, and TBXA2R. Pathway analysis revealed that AR-specific herbs were associated with multiple AR-related pathways, including cytokine signaling, immune response, and allergic inflammation. Additionally, clustering analysis based on target similarity identified three distinct subgroups of AR-specific herbs, corroborated by a protein-protein interaction network. Group 1 herbs were associated with the regulation of inflammatory responses to antigenic stimuli, while Group 2 herbs were related to the detection of chemical stimuli involved in the sensory perception of bitter taste. Group 3 herbs were distinctly associated with antigen processing and presentation and NIK/NF-kappa B signaling. This study decodes the principles of TAM herbal configurations for AR using a network pharmacological approach, providing a holistic understanding of drug effects beyond specific pathways.

Abstract
BACKGROUND Considering the vital role of vascular endothelial growth factor (VEGF) in the development of diabetic retinopathy (DR) in one hand and the frequent association between subclinical hypothyroidism (SCH) and DR on the other hand. OBJECTIVE The present study was proposed to explore the possible role of VEGF in the relation between SCH and DR, thus we investigated the relation between SCH and VEGF levels in patients with DR. METHODS Two hundred patients with DR were recruited in this study [100 patients with proliferative diabetic retinopathy (PDR) and 100 patients with non-proliferative diabetic retinopathy (NPDR)]. Patients with DR were divided into 2 groups according to thyroid function: patients with SCH or those with euthyroidism. Patients were subjected to careful history taking, and underwent clinical and ophthalmological examination. Fasting blood glucose, glycosylated hemoglobin, fasting insulin, homeostasis model assessment of insulin resistance (HOMA-IR), TSH, FT4, FT3, VEGF and thyroid volume were assessed Results: Among all the studied patients, 21.5% (43/200) had SCH. DR patients with SCH had higher age, diabetes duration, HbA1c, HOMA-IR and VEGF than those with euthyroidism. The frequency of PDR in patients with SCH was 72.1% (31/43) and 43.9% (69/157) in those with euthyroidism, whereas the frequency of NPDR in patients with SCH was 27.9 (12/43) and 56.1% (88/157) in those with euthyroidism (P < 0.003). In multivariate analysis, PDR, HOMA-IR and VEGF levels were the significant predictor variables of SCH. CONCLUSIONS Increased VEGF levels may be implicated in the relationship between SCH and DR.

Abstract
Background: Angiogenesis is well known to be an important event in the tissue remodeling observed in allergic diseases. Although there is much evidence that quercetin, one of the most abundant dietary flavonoids, exerts anti-allergic effects in both human and experimental animal models of allergic diseases, the action of quercetin on angiogenesis has not been defined. Therefore, in this study, we first examined the action of quercetin on the secretion of angiogenic factors from murine mast cells in vitro. We also examined the action of quercetin on angiogenic factor secretion in the murine allergic rhinitis model in vivo. Methods: Mast cells (1 × 105 cells/mL) sensitized with ovalbumin (OVA)-specific murine IgE were stimulated with 10.0 ng/mL OVA in the presence or the absence of quercetin for 24 h. The concentrations of angiogenic factors, vascular endothelial growth factor (VEGF), basic fibroblast growth factor (bFGF), tumor necrosis factor-α, IL-6 and IL-8 in the supernatants were examined by ELISA. BALB/c male mice immunized with OVA were challenged intranasally with OVA every other day, starting seven days after the final immunization. These mice were then orally administered quercetin once a day for five days, starting seven days after the final immunization. Clinical symptoms were assessed by counting the number of sneezes and nasal rubbing behaviors during the 10 min period just after OVA nasal provocation. The angiogenic factor concentrations in the nasal lavage fluids obtained 6 h after nasal antigenic provocation were examined by ELISA. Results: Quercetin significantly inhibited the production of angiogenetic factors induced by IgE-dependent mechanisms at 5.0 µM or more. Oral administration of 25.0 mg/kg quercetin into the mice also suppressed the appearance of angiogenetic factors in nasal lavage fluids, along with the attenuation of nasal symptoms. Conclusions: These results strongly suggest that the inhibitory action of quercetin on angiogenic factor secretion may be implicated in the therapeutic action of quercetin on allergic diseases, especially allergic rhinitis.

Abstract
BACKGROUND As part of the planning for a future multicenter study, this preliminary clinical trial used serum samples from patients to identify biomarkers for predicting the therapeutic effects of sublingual immunotherapy (SLIT) for Japanese cedar pollinosis (JCP). METHODS This prospective study included patients undergoing SLIT for JCP at our hospital. All enrolled patients (N = 17) started SLIT between June and November of 2015. With informed consent from the patients, blood samples were obtained in January, March, and June of 2016, and patients completed the Japan rhino-conjunctivitis quality of life questionnaire (JRQLQ). On the basis of the JRQLQ results, the 6 patients with the best outcomes were included in the high-response group (HRG), and the 5 patients with the worst outcomes were included in the poor-response group (PRG). We then compared serum data between the two groups, to identify useful biomarkers. RESULTS IL-12p70 and VEGF levels tended to be higher in the HRG than in the PRG in January, March, and June (0.10 > p > 0.05). In addition, the June IL-17 level was significantly higher (p < 0.05) in the HRG than in the PRG. CONCLUSIONS IL-12p70 and VEGF may be useful biomarkers for predicting the effects of SLIT. In addition, although IL-17 does not appear to be useful as a biomarker for evaluating treatment response at the start of SLIT, it may be useful as a biomarker after the beginning phase of SLIT.

Identification of rare variants of allergic rhinitis based on whole genome sequencing and gene expression profiling: A preliminary investigation in four families. World Allergy Organ J 2019; 12:100038. [PMID: 31236190 PMCID: PMC6581771 DOI: 10.1016/j.waojou.2019.100038] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/02/2018] [Revised: 04/02/2019] [Accepted: 05/14/2019] [Indexed: 12/13/2022] Open
Abstract
Background Despite the success of genome-wide association studies for allergic rhinitis (AR), no definitive causal variants have been identified, and a substantial portion of the heritability of the disease is yet to be discovered. Methods Four families, each with at least 1 parent and one child suffering from dust mite (DM) AR, were recruited, and whole-genome sequencing was performed on samples from 9 eligible individuals from these families. Conjoint analysis was performed for existing gene expression profiling data in the literature and the whole genome sequencing data obtained for these individuals; for presence of family-specific variants segregating with AR and the pathways involved. Similar analyses were also performed with data obtained for 96 sporadic house dust mite (HDM) AR patients and 96 healthy controls. Results Three rare variants in three genes (FLT1_c.603A > T; VEGFB_c.322A > C; and ITGA2_c.502+1G > A), which are involved in Focal Adhesion pathway, were identified in affected, but not unaffected, subjects in two families. VEGFB_c.322A > C and/or ITGA2_c.502+1G > A were further detected in all DM AR patients but not in any healthy individuals in 1 family; which was further investigated for members. The 3 identified variants were not found in any of the sporadic DM AR patients or healthy controls. Conclusion Despite the relatively small sample size, this study has identified several potentially functional rare variants in AR candidate genes, and it provides a platform for future work in larger numbers of families and sporadic individuals for a better understanding of the genetic basis of AR.

Abstract
BACKGROUND Asthma is associated with adverse pregnancy outcomes. At the same time there is a worldwide increase in asthma and hay fever. OBJECTIVE This study addresses whether asthma and/or hay fever adversely influence pregnancy outcomes. METHODS Data from the 1995 National Survey of Family Growth that include a history of diagnosed asthma, hay fever, and adverse pregnancy outcomes in 10,847 women representative of the US population aged 15 to 44 years were analyzed. RESULTS Women with the allergic phenotypes asthma and hay fever and hay fever only had no significant increase in adverse pregnancy outcomes (spontaneous pregnancy loss, preterm birth, infant low birth weight), whereas women with the nonatopic phenotype asthma only (without hay fever) did. The study did not evaluate endotypes. CONCLUSIONS This study provides new data that the allergic phenotypes, asthma and hay fever and hay fever only, are compatible with healthy pregnancy, whereas the nonatopic asthma phenotype, asthma only, adversely impacts pregnancy.

Abstract
ABSTARCT Epidemiological and clinical studies have increasingly shown that fine particulate matter (PM2.5) is associated with a number of pathological respiratory diseases, such as bronchitis, asthma, and chronic obstructive pulmonary disease, which share the common feature of airway inflammation induced by particle exposure. Thus, understanding how PM2.5 triggers inflammatory responses in the respiratory system is crucial for the study of PM2.5 toxicity. In the current study, we found that exposing human bronchial epithelial cells (immortalized Beas-2B cells and primary cells) to PM2.5 collected in the winter in Wuhan, a city in southern China, induced a significant upregulation of VEGFA (vascular endothelial growth factor A) production, a signaling event that typically functions to control chronic airway inflammation and vascular remodeling. Further investigations showed that macroautophagy/autophagy was induced upon PM2.5 exposure and then mediated VEGFA upregulation by activating the SRC (SRC proto-oncogene, non-receptor tyrosine kinase)-STAT3 (signal transducer and activator of transcription 3) pathway in bronchial epithelial cells. By exploring the upstream signaling events responsible for autophagy induction, we revealed a requirement for TP53 (tumor protein p53) activation and the expression of its downstream target DRAM1 (DNA damage regulated autophagy modulator 1) for the induction of autophagy. These results thus extend the role of TP53-DRAM1-dependent autophagy beyond cell fate determination under genotoxic stress and to the control of proinflammatory cytokine production. Moreover, PM2.5 exposure strongly induced the activation of the ATR (ATR serine/threonine kinase)-CHEK1/CHK1 (checkpoint kinase 1) axis, which subsequently triggered TP53-dependent autophagy and VEGFA production in Beas-2B cells. Therefore, these findings suggest a novel link between processes regulating genomic integrity and airway inflammation via autophagy induction in bronchial epithelial cells under PM2.5 exposure.

Abstract
We describe a 39-year-old woman with metastatic breast cancer who had grade 4 epistaxis induced by bevacizumab. The patient visited our outpatient clinic with complaints of a lump in her right breast, fatigue, dyspnea, abdominal distention, appetite loss, and weight loss of 10 kg over 1 year. Liver dysfunction was detected, with elevated levels of aspartate aminotransferase (271 IU/L), alanine aminotransferase (100 IU/L), alkaline phosphatase (4,205 IU/L), total bilirubin (2.7 mg/dL), and direct bilirubin (2.1 mg/dL). A secondary liver tumor that occupied most of the liver volume was found, and bone metastasis, ascites, and pleural effusion were also discovered. The Eastern Cooperative Oncology Group performance status was 2. A core needle biopsy of the right breast tumor revealed invasive ductal carcinoma of the breast (nuclear grade 1) that was positive for estrogen receptor and progesterone receptor and negative for human epidermal growth factor receptor 2 overexpression and had a high Ki-67 score. We chose combination chemotherapy with paclitaxel (80 mg/m(2) on days 1, 8, and 15) and bevacizumab (10 mg/kg on days 1 and 15) for 28 days (1 cycle). After completion of the first cycle of chemotherapy, the ascites and pleural effusion decreased, and the metastatic liver tumor shrank. The performance status improved from 2 to 1. On day 3 of the third cycle of chemotherapy, however, she began having persistent epistaxis. On day 6, she lost consciousness and was transported to the emergency room of our hospital. The hemoglobin level was 5.6 g/dL. Blood transfusion and endoscopic hemostasis were immediately started. Bevacizumab was discontinued, and paclitaxel alone was continued; after this change, epistaxis did not recur.

Abstract
UNLABELLED Nasal lavage fluid (NLF) becomes more and more important as a noninvasive patient sample serving as a new opportunity to discover new biomarkers in diverse human diseases comprising mainly respiratory disorders. This was supported by the observation that the protein profile of NLF differs from conventional samples of i.e. whole blood, hence being capable to complement or even expand the so far biomarker index. Since sample acquisition and processing are the most crucial steps for a profound and sensitive identification we present here a modified protocol of NLF generation and measurement. We show that mild washing steps for sample generation followed by column-mediated concentration and acetone precipitation are appropriate steps to minimize serum leakage by concomitantly highlighting proteins which represent typical components of NLF. This is shown by separation of proteins via 2D-PAGE followed by LC-MS/MS as well as Gel-LC-MS/MS measurements of cut and digested protein spots/bands. SIGNIFICANCE For a better understanding of the molecular mechanisms underlying respiratory diseases NLF samples are favored sources for protein research. NLF acquisition and sample processing were impaired so far by the problem of blood serum leakage and high salt content. Here, we present a modified protocol of NLF generation leading to the display of typical inventory of NLF proteins combined with reduced salt and serum contaminants. By this, both assay reproducibility and the detection of up- or down-regulated proteins reliably can be discovered in the case of biomarker screenings in a disease versus control design. This article is part of a Special Issue entitled: Neuroproteomics: Applications in Neuroscience and Neurology.

Abstract
The nasal provocation test (NPT) is a simple procedure with high specificity and sensitivity that is used in the investigation of allergic and nonallergic diseases. Uniform standards are of particular importance in the clinical setting and for the comparability of clinical and basic allergy research. These standards should cover the composition, dosage and pharmacological formulation of provocative substances (e.g. allergen extracts), the necessity of titration, allergen application methods and the evaluation criteria for a positive NPT reaction. Detection of various mediators and cytokines in nasal discharge can be very useful in the late phase reactions. NPT finds specific applications in studies of local IgE secretion in the nasal mucosa, the diagnosis of analgesic intolerance and in assessments of the efficacy of specific immunotherapies. Additional parameters warranting further evaluation include provocation with cold dry air in nasal hyperreactivity patients and nasal nitric oxide formation. Determination of nasal blood flow during NPT provides an additional clinical parameter.

Abstract
Hemorrhagic fever with renal syndrome (HFRS) is an acute infectious disease characterized by endothelial cell dysfunction, which results in plasma exosmosis, hyperpermeability, and sometimes hemorrhages. As one of the vascular permeability cytokines, vascular endothelial growth factor (VEGF) might mediate the hyperpermeability caused by HFRS. In the present study, the levels of serum VEGF were measured by competitive inhibition ELISA. We found variable but persistently elevated levels of VEGF throughout the various stages and types of HFRS disease, which suggested that the levels of VEGF were closely correlated to the progression of HFRS. Moreover, elevated levels of VEGF have correlation with the severity and degree of kidney damage. Therefore, to study the relationship between levels of VEGF and disease severity of patients with HFRS is helpful to clarify the pathogenesis of HFRS.
