Allergic rhinitis (AR) is a common allergic disease globally and its prevalence is increasing year by year. This study aimed to analyze the prevalence and risk factors of self-reported AR among the Chinese National Railway train crew in the China Railway Beijing Group. This prospective questionnaire study surveyed 1511 randomly recruited train crewmembers from 20 cities in the China National Railway network, and 494 reported having AR.

To understand the sensitization characteristics of humulus pollen in patients with allergic rhinitis or allergic asthma in Beijing, and to explore the proportion of the population allergic to humulus pollen. Selected 8380 patients who were diagnosed with allergic rhinitis, allergic asthma, and allergic rhinitis combined with asthma in outpatient clinic from January 2017 to December 2019. SPT test was performed with humulus allergen reagent to compare the sensitization distribution of humulus pollen by age and disease, and analyze the sensitization characteristics of humulus pollen.

Background: Artemisia weed pollen allergy is important in the northern hemisphere. While over 350 species of this genus have been recorded, there has been no full investigation into whether different species may affect the allergen diagnosis and treatment. This study aimed to evaluate the variations in amino acid sequences and the content of major allergens, and how these affect specific IgE binding capacity in representative Artemisia species.

The distribution and sensitization characteristics of the pollen of artemisia were analyzed in the grasslands of Inner Mongolian. A face-to-face questionnaires survey about the distribution and sensitization characteristics of the pollen of artemisia was performed together with pollen skin prick tests(SPTs) and measurements of the daily pollen count in 6 region(Xilinhot, Erenhot, Duolun, Tongliao, Jarud, Kailu) in the grasslands of Inner Mongolian. A total of 6043 subjects completed the study.

Methods: Adult patients diagnosed with CAP admitted between January 2017 and May 2019 with admission SOFA ≥2 from baseline were enrolled. Demographic characteristics were collected.
Background: Community-acquired pneumonia (CAP) is a leading cause of sepsis and common presentation to emergency department (ED) with a high mortality rate. The prognostic prediction value of sequential organ failure assessment (SOFA) and quick SOFA (qSOFA) scores in CAP in ED has not been validated in detail. The aim of this research is to investigate the prognostic prediction value of SOFA, qSOFA, and admission lactate compared with that of other commonly used severity scores (CURB65, CRB65, and PSI) in septic patients with CAP in ED.

This study aims to assess the clinical relevance of serum inhibitory activity for IgE by the method of enzyme-linked immunosorbent facilitated antigen binding (ELIFAB) during SCIT for Artemisia-sensitized AR patients.
Methods: 19 AR patients were studied who had undergone Artemisia-specific SCIT for more than 8 months (19.
Background: Community-acquired pneumonia (CAP) is a potentially life-threatening condition. The aim of this study is to investigate the stratified and prognostic value of admission lactate and severity scores (confusion, urea >7 mmol/L, respiratory rate ≥30/min, blood pressure <90 mm Hg systolic and/or ≤60 mm Hg diastolic, and age ≥65 years [CURB65], pneumonia severity index [PSI], sequential organ failure assessment [SOFA], qSOFA) in patients with CAP in emergency department.
Methods: Adult patients diagnosed with CAP admitted between January 2017 and January 2019 were enrolled and divided into severe CAP (SCAP) group and nonSCAP (NSCAP) group according to international guidelines, death group, and survival group according to 28-day prognosis.
Severity stratification and prognostic prediction at early stage is crucial for reducing the rates of mortality of patients with acute pancreatitis (AP). We aim to investigate the predicting performance of neutrophil-lymphocyte ratio (NLR), platelet-lymphocyte ratio (PLR), and red-cell distribution width (RDW) combined with severity scores (sequential organ failure assessment [SOFA], bed-side index for severity of AP [BISAP], Ranson criteria, and acute physiology and chronic health evaluation II [APACHE II]) for severe AP (SAP) and mortality.A total of 406 patients diagnosed with AP admitted in a tertiary teaching hospital were enrolled.

The aim of our study is to investigate the risk stratification and prognostic prediction value of precalcitonin (PCT) and clinical severity scores on patients with CAP in ED.
Methods: 226 consecutive adult patients with CAP admitted in ED of a tertiary teaching hospital were enrolled.
Background: Retroperitoneal fibrosis (RPF) is an uncommon disease that is characterized by development of fibrosclerotic tissues involving retroperitoneal structures. This study aimed to investigate the clinical features of 30 patients with RPF in a single center in Beijing in a 10-year period.
Methods: We retrospectively analyzed clinical data on demographic characteristics, clinical manifestations, laboratory findings, radiological findings, modalities of treatments, outcomes and prognosis of 30 patients with RPF.
We hereby introduce a rare case of ruptured renal artery aneurysm and make a simple description of this urologic emergency entity to enhance our awareness of this disease.

Lung cancer is a major cause of disease and loss of life in the United States and worldwide. Cancer cells release immunosuppressive mediators, such as PGE2, TGF-β, IL-10, and VEGF, to inhibit the immune response to escape from immune surveillance.
View Article and Find Full Text PDFImmune responses to tumor-associated antigens are often detectable in tumor-bearing hosts, but they fail to eliminate malignant cells or prevent development of metastases. Tumor cells produce factors such as interleukin-10, transforming growth factor-β1 and vascular endothelial growth factor (VEGF) that suppress the function of immune cells or induce apoptosis of immune cells. Culture supernatant of tumor cells may contain these immunosuppressive factors which suppress lymphocyte activation.

Antitumor response can be launched by a series of events, starting with inflammation mediated by monocyte/macrophages, which stimulates natural killer and dendritic cells and finally activates the cytotoxic lymphoid system. Monocytes/macrophages may be the first line of defense in tumors.

One of the most important goals of tumour immunotherapy is to antagonize this suppression on immune cells. Ganoderma lucidum polysaccharides (Gl-PS) may have this potential.
