BACKGROUND: Pulmonary inflammatory myofibroblastic tumor (PIMT) is a rare disease in China and its incidence is much lower than that of tuberculosis. PIMT accounts for only 0.04-1.2% of all lung tumors. PIMT can occurs in any age and nearly every part of the body. The clinical symptoms and radiological features of PIMT are nonspecific. Diagnosis is only made on the basis of histopathologic or immunohistochemical evaluation of the postoperation resected tissue. The therapeutic approach to PIMT should rely mainly on complete surgical resection...

Osteosarcoma (OS) is an ultra-rare highly malignant tumor of the skeletal system affecting mainly children and young adults and it is characterized by an extremely aggressive clinical course. OS patients are currently treated with chemotherapy and complete surgical resection of cancer tissue. However, resistance to chemotherapy and the recurrence of disease, as pulmonary metastasis, remain the two greatest challenges in the management and treatment of this tumour. For these reasons, it is of primary interest to find alternative therapeutic strategies for OS...

Although it is well established that tumor-associated macrophages take part in each step of cancer progression, less is known about the distinct role of the so-called metastasis-associated macrophages (MAMs) at the metastatic site. Previous studies reported that Caveolin-1 (Cav1) has both tumor-promoting and tumor-suppressive functions. However, the role of Cav1 in bone-marrow-derived cells is unknown. Here, we describe Cav1 as an anti-metastatic regulator in mouse models of lung and breast cancer pulmonary metastasis...

Background The National Wilms Tumor Study (NWTS) approach to treating stage III favorable-histology Wilms tumor (FHWT) is Regimen DD4A (vincristine, dactinomycin, and doxorubicin) and radiation therapy. Further risk stratification is required to improve outcomes and reduce late effects. We evaluated clinical and biologic variables for patients with stage III FHWT without combined loss of heterozygosity (LOH) at chromosomes 1p and 16q treated in the Children's Oncology Group protocol AREN0532. Methods From October 2006 to August 2013, 588 prospectively treated, centrally reviewed patients with stage III FHWT were treated with Regimen DD4A and radiation therapy...

Brain metastases from NSCLC are associated with a poor prognosis, and local radiotherapy is the most effective therapeutic strategy. The oncofetal protein IMP3 has been studied extensively, and evidence suggests that its expression is related to shorter overall survival and a more aggressive phenotype in solid malignancies. Here, the prognostic role of IMP3 was investigated in a cohort of patients with NSCLC brain metastases in correlation with survival and tumor histotype. A series of 42 NSCLC brain metastases samples was analyzed by tissue microarray and immunohistochemical staining for IMP3...

Accumulating evidence indicates that microRNAs (miRNAs) play important roles in tumorigenesis and metastasis. Recent research has shown that miR‑196b is implicated in metastasis by regulating the migration and invasion of cancer cells. However, the clinical significance of miR‑196b and its role as well as the underlying mechanisms in hepatocellular carcinoma (HCC) remain largely unknown. Here, we detected miR‑196b expression in HCC and matched non-tumor tissues with qRT‑PCR. We found that miR‑196b displayed higher expression in HCC patient tissues and cells...

Baicalin exhibits antibacterial, anti‑viral, anti‑oxidative, antipyretic, analgesic, anti‑inflammatory and anti‑tumor properties. The chemical scavenges oxygen free radicals, protects the cardiovascular system and neurons, protects the liver, and has been used for the prevention and treatment of diabetes‑associated complications. The present study investigated the effect of baicalin on severe burn‑induced remote acute lung injury (ALI). The present study demonstrated that baicalin significantly decreased the lung wet‑to‑dry weight ratio, improved pulmonary histological alterations and reduced the expression of high mobility group protein B1 in the rat model of ALI...

A variety of bacteria have been used as agents and vectors for antineoplastic therapy. A series of mechanisms, including native bacterial toxicity, sensitization of the immune system and competition for nutrients, may contribute to antitumor effects. However, the antitumor effects of Proteus species have been minimally studied, and it is not clear if bacteria can alter tumor hypoxia as a component of their antineoplastic effect. In the present study, Proteus mirabilis bacteria were evaluated for the ability to proliferate and accumulate in murine tumors after intravenous injection...

BACKGROUND: Angiotensin II plays a vital role in the pathogenesis of acute respiratory distress syndrome (ARDS). However, its mechanism is not well defined. Angiotensin II up-regulates the expression of soluble epoxide hydrolase (sEH; Ephx2). sEH is suggested as a potential pharmacologic target for ARDS. The present study investigates whether the sEH is involved in the angiotensin II triggered pulmonary inflammation and edema using an angiotensin II-induced lung injury animal model. METHODS: Lung injury was induced by angiotensin II intratracheally instillation in wild-type or Ephx2 deficient mice...

Platelet activation plays a major role in cardio and cerebrovascular diseases, and cancer progression. Disruption of platelet activation represents an attractive therapeutic target for reducing the bidirectional cross talk between platelets and tumor cells. Platinum (Pt) compounds have been used for treating cancer. Hence, replacing Pt with iridium (Ir) is considered a potential alternative. We recently developed an Ir(III)-derived complex, [Ir(Cp*)1-(2-pyridyl)-3-(2-hydroxyphenyl)imidazo[1,5-a]pyridine Cl]BF₄ (Ir-11), which exhibited strong antiplatelet activity; hence, we assessed the therapeutic potential of Ir-11 against arterial thrombosis...

BACKGROUND: Detection of tumor cells in lymph nodes (LNs) removed during the treatment of pulmonary tumor by radical surgery is limited by the possibilities of standard histopathological methods. The goal of this study was to obtain more accurate pTNM status by a more sensitive detection of micrometastases in LNs. METHODS: A total of 885 LNs, an average of 13.8 LNs per patient, were removed during 64 surgeries. LNs from the same zone were pooled together as a group, five groups of LNs were examined in each patient...

Cigarette smoke (CS) exposure is an important risk factor for chronic obstructive pulmonary disease (COPD). MicroRNA-150 (miR-150) is involved in several inflammatory diseases. However, little is known about the role of miR-150 in the pathogenesis of COPD. In this study, we established a CS-related mouse model of COPD and evaluated the impact of miR-150 on CS-induced lung inflammation. We further investigated the effects of miR-150 overexpression on pro-inflammatory cytokine production and apoptosis in airway epithelial cells exposed to CS extract (CSE)...

Pulmonary arterial hypertension (PAH) is a progressive disease characterized by proliferative changes in pulmonary arteries. There is growing evidence suggesting that soluble tumor necrosis factor-like weak inducer of apoptosis (sTWEAK) and P-selectin could be involved in PAH development and progression. Here we investigate whether circulating platelets may be a source of sTWEAK and contribute to diminished availability of sTWEAK and P-selectin in PAH patients. We have prospectively enrolled two independent study groups of stable patients with confirmed PAH and age matched controls: derivation (10 PAH; 15 controls) and validation (20 PAH; 12 controls)...
