The present study aimed to detect the bone Ca(2+) content of L3 vertebrae in adults by gemstone spectral computed tomography. In total, 235 patients were selected and divided into age groups of 10 years each. The scanning data were used to detect the water-based and Ca(2+)-based substance levels on the L3 vertebral cancellous bone images. The results indicated that there were significant differences in vertebral Ca(2+)-water and water-Ca(2+) densities determined by gemstone spectral imaging (GSI) between males and females in subjects aged 50-59 years, 60-69 years, 70-79 years and ≥80 years (P<0...

Asthma is a chronic bronchial inflammation that results to reversible incidence of airway obstruction and shortness of breath. Under normal circumstances, the lung immune system is maintained in a state of controlled inflammation, where balance exists between protective immunity mediated by effector cells and tolerance mediated by cells with regulatory function. Therefore, the inflammation observed in asthma patients may be caused by an imbalance between regulatory T (Treg) cells (CD4-positive with high expression of CD25 surface markers) and forkhead box P3 (FOXP3)-positive pro-inflammatory T helper 17 (Th17) cells...

Shikonin has previously been shown to have antitumor, anti-inflammatory, antiviral and extensive pharmacological effects. The aim of the present study was to explore whether the protective effect of shikonin is mediated via the inhibition of inflammation and chondrocyte apoptosis, and to elucidate the potential molecular mechanisms in a rat model of osteoarthritis. A model of osteoarthritis was established in healthy male Sprague-Dawley rats and 10 mg/kg/day shikonin was administered intraperitoneally for 4 days...

Drug-induced liver injury (DILI) is often undiagnosed or misdiagnosed clinically because of diagnostic difficulties caused by lack of laboratory-specific serological markers. In this study, we comprehensively assessed the clinical characteristics, laboratory indices, hepatotoxic drugs, risk factors and outcomes concerning DILI, and explored the similarities in mechanisms between Chinese and Western drug-induced DILI. Patients with a first diagnosis of DILI and a Roussel Uclaf Causality Assessment Method (RUCAM) score >3 points were enrolled for systematic retrospective study...

Toll-like receptor 4 (TLR4) is involved in the regulation of host responses to Acinetobacter baumannii (A. baumannii). The aim of the present study was to examine the function of TLR4 in lung inflammation in immune-suppressed rats with A. baumannii infection. A total of 72 Sprague-Dawley male rats were randomly divided into the control, A. baumannii infection and immune-suppressed infection groups. The immune-suppressed infection group was treated with 100 mg/kg hydrocortisone by subcutaneous injection every other day for 2 weeks prior to A...

Exogenous and endogenous opioids have been shown to modulate the immune system. Morphine-induced immunosuppression has been investigated extensively. However, the immune-regulating function of endogenous opioid peptides is unclear. The present study aimed to evaluate the difference in effects on cellular immune function between recombinant rat β-endorphin (β-EP; 50 µg/kg) and plant source morphine (10 mg/kg) via intraperitoneal injection treatment in a rat model of bone cancer pain. Walker 256 cells were injected into a tibial cavity injection to establish the bone cancer pain model...

Ginsenoside Rb1 (GRb1), which is one of the main ingredients derived from Panax ginseng, has been widely used to treat various gastrointestinal disorders. The present study aimed to determine whether GRb1 was able to prevent intestinal mucosal barrier damage in rats following peritoneal air exposure for 3 h. GRb1 (5, 10, and 20 mg/kg) was orally administrated via gavage four times prior to and following surgery. Blood and terminal ileum were sampled 24 h following surgery. Levels of serum D-lactate (D-LA) were detected using an enzyme-linked immunosorbent assay kit...

The aim of the present study was to investigate the influence of the random urine albumin-creatinine ratio (ACR) of pregnant women with hypertension during the gestation period on perinatal outcome. A total of 6,758 pregnant women with pregnancy-induced hypertension and proteinuria were randomly selected between September, 2009 and June, 2015 for the study. Kidney function, blood pressure, history of gravidity and parity, embryo number and the birth weight of the participants was determined. Logistic regression and paired data correlation analyses were carried out with kidney function, blood pressure, history of gravidity and parity, embryo number, birth weight, maternal age, labor presentation and other risk factors as the independent variables and the newborn APGAR score as the dependent variable...

Multiple sclerosis (MS) is easily detected by routine magnetic resonance imaging (MRI). However, it is not possible to detect early or occult lesions in MS by routine MRI, and this may explain the inconsistency between the severity of the lesions found by MRI and the degree of clinical disability of patients with MS. The present study included 10 patients with relapsing-remitting MS and 10 healthy volunteers. Each patient underwent routine 3.0 T MRI, diffusion tensor imaging (DTI), and diffusion tensor tractography (DTT)...

Adrenergic β-blockers are drugs that bind to, but do not activate β-adrenergic receptors. Instead they block the actions of β-adrenergic agonists and are used for the treatment of various diseases such as cardiac arrhythmias, angina pectoris, myocardial infarction, hypertension, headache, migraines, stress, anxiety, prostate cancer, and heart failure. Several meta-analysis studies have shown that β-blockers improve the heart function and reduce the risks of cardiovascular events, rate of mortality, and sudden death through chronic heart failure (CHF) of patients...

An avian-origin influenza H7N9 virus epidemic occurred in China in 2013-2014, in which >422 infected people suffered from pneumonia, respiratory distress syndrome and septic shock. H7N9 viruses belong to the H7 subtype of avian-origin influenza viruses (AIV-H7). Hemagglutinin (HA) is a vital membrane protein of AIV that has an important role in host recognition and infection. The epitopes of HA are significant determinants of the regularity of epidemic and viral mutation and recombination mechanisms. The present study aimed to predict the conserved B-cell epitopes of AIV-H7 HA using a bioinformatics approach, including the three most effective epitope prediction softwares available online: Artificial Neural Network based B-cell Epitope Prediction (ABCpred), B-cell Epitope Prediction (BepiPred) and Linear B-cell Epitope Prediction (LBtope)...

The imbalance between energy intake and expenditure is the main cause of excessive overweight and obesity. Technically, obesity is defined as the abnormal accumulation of ≥20% of body fat, over the individual's ideal body weight. The latter constitutes the maximal healthful value for an individual that is calculated based chiefly on the height, age, build and degree of muscular development. However, obesity is diagnosed by measuring the weight in relation to the height of an individual, thereby determining or calculating the body mass index...

The universal endocrine pathological state affecting young individuals and adults is type 2 diabetes mellitus, which has seen a significant increase in the last 30 years, particularly in children. Genetic and evnironmental factors are the causative agents for this pathological state in children. This rapid and wide spread of the disease can be controlled by enforcing amendments in environmental factors such as diet, physical activities and obesity. In young infants breastfeeding may be a key modulator of the disease...

Allergic rhinitis (AR) is a risk factor for asthma development. The value of fractional exhaled nitric oxide (FeNO) in detecting lower airway involvement in the progress of AR-asthma march has not been evaluated. The aim of the present study was to investigate the value of FeNO in assessing lower airway inflammation and predicting bronchial hyperresponsiveness (BHR) in AR with or without asthma. FeNO and eosinophil count in induced sputum, and a methacholine bronchial provocation test were performed in 93 subjects, including: 45 AR patients (AR group); 20 patients with AR and asthma (AR with asthma group); and 28 normal controls (control group)...
