Background: The E3 ubiquitin ligase neural precursor cell expressed developmentally downregulated 4-1 (NEDD4-1) negatively regulates phosphatase and tensin homolog deleted on chromosome 10 (PTEN) protein levels through polyubiquitination and proteolysis, but its significance in lung cancer is still unclear. This study investigated the expression and the role of NEDD4-1 in tumor development and chemosensitivity of lung adenocarcinoma (ADC).

Methods: We retrospectively investigated the expression and significance of NEDD4-1, PTEN, and p-Akt proteins in 135 paired ADC and adjacent noncancerous tissue specimens using immunohistochemistry.

Aim: The aim of this study was to investigate the alterations of pulmonary function tests (PFTs) and their relationship with disease activity in inflammatory bowel diseases (IBDs).

Methods: Sixty-four IBD patients (31 Crohn's disease [CD] and 33 ulcerative colitis [UC]) and thirty healthy individuals (controls) were studied with regard to the following parameters of PFTs: Forced expiratory volume in 1 s (FEV1), forced vital capacity (FVC), their ratio, mid-forced expiratory flow of 25-75% (FEF 25-75), residual volume, total lung capacity, and diffusing capacity of the lung for carbon monoxide (DLCO). The disease activity was calculated using the Crohn's Disease Activity Index for CD and Mayo Clinic Score for UC.

Gastrointestinal stromal tumors (GISTs) are the most common type of mesenchymal tumor of the gastrointestinal tract. The stomach and small intestine are the most common sites of occurrence. GISTs are mesenchymal neoplasms originating from the interstitial cells of Cajal (ICCs), and are characterized by positivity for cluster of differentiation (CD) 117, also known as proto-oncogene c-Kit.

This study aimed to investigate the effect of ambroxol on the concentration of cefotaxime in the bronchioalveolar lavage fluid of rats with bleomycin-induced pulmonary fibrosis. A total of 54 Wistar male rats were randomly divided into three groups, namely the normal control group, model group and ambroxol group. On experimental day 0, the rats were intratracheally instilled with bleomycin (5 mg/kg body weight) or sterile saline.

Crohn's disease (CD) is a systemic illness with a constellation of extraintestinal manifestations affecting various organs. Of these extraintestinal manifestations of CD, those involving the lung are relatively rare. However, there is a wide array of lung manifestations, ranging from subclinical alterations, airway diseases and lung parenchymal diseases to pleural diseases and drug-related diseases.

Objective: To assess the clinical efficacy and safety of surrounding needle, moxibustion and hot compress of TCM herbs for localized scleroderma.

Methods: Forty-two cases of localized scleroderma were randomly divided into an acupuncture + herb group (23 cases, group A) and a heparin sodium group (19 cases, group B). Both the two groups were orally administrated with centella triterpenes tablets and vitamin E, group A was additionally treated with surrounding needle at local area, moxibustion at affected site and Hegu (LI 4), Zu sanli (ST 36) as well as hot external application of "hot compress herbs" at local location, while group B was treated with external application of heparin sodium cream.

Aim: To investigate the roles of Th17 lymphocytes and its inflammatory cytokines in airway inflammation exacerbation of murine asthmatic model.

Methods: Twenty mice were randomized into control group and asthma group. For the murine asthma model, the mice were sensitized and challenged with ovalbumin (OVA).

Objective: To explore the mechanism of Wenfei Huayin Recipe (WHR) in treating chronic obstructive pulmonary diseases (COPD).

Methods: The COPD model was induced by modified fumigating method and intra-tracheal instillation of lipopolysaccharide. Then reformed COPD model of cold-phlegm retention in Fei syndrome type.

Aim: To investigate the effects of Hax-1 siRNA on sensitivity to chemotherapy of melanoma A375 cells.

Methods: The effects of Hax-1 siRNA combined with cisplatin(DDP) or Matrine(Mat) on proliferation, apoptosis of A375 cells and active forms of caspase-3 were detected with MTT assay, Annexin V-FITC/PI staining with FCM, Hoechst 33258 staining, and Western blot respectively.

Results: The inhibition of proliferation , induction of apoptosis and the expression of active caspase-3 forms in DDP or Mat treated A375 cells transfected with Hax-1 siRNA were all significantly higher than those in untransfected A375 cells or A375 cells transfected with control siRNA (P<0.

HS1-associated protein X-1 (Hax-1) is a novel intracellular protein and recent studies suggested that it is an anti-apoptotic factor in different tumors. Hax-1 expression was upregulated in various metastatic tumors and cancer cell lines, including melanoma. To understand the role of Hax-1 in melanoma development and progression, we constructed Hax-1 short interfering RNA (siRNA) expression vectors to downregulate Hax-1 expression in a human melanoma A375 cell line.

Unlabelled: To observe the clinical effect of drug cupping therapy (DCT, cupping therapy with pingchuan ointment made by the authors themselves in the cups) on chronic asthmatic bronchitis (CAB) during the protracted period, and explore its effect on immune function.

Methods: Seventy-seven patients were randomly divided into two groups:the treated group (n=40) treated by orally taken Liuwei Dihuang Pill (LDP) and DCT and the control group (n=37) with LDP and common cupping therapy without drug in cups. The changes of T-lymphocyte subset, levels of interferon-gamma (IFN-gamma), interleukin (IL), immunoglobulin (Ig), complement 3 and 4 (C3 and C4) were detected before and after treatment.

Objective: To study the relationship between the expression of transforming growth factor-beta(1) (TGF-beta(1)) and platelet derived growth factor (PDGF) and airway remodeling in eosinophilic bronchitis (EB).

Methods: Bronchial biopsy specimens were obtained from 12 patients with EB (A group), 10 asthmatic patients (B group) and 10 patients (C group) with peripheral lung cancer in early stage. The subepithelial basement membrane (SBM) thickness was measured by light microscopy using HE staining.

Objective: To investigate the effect of Tongxinluo capsule (TXLC) on the patients with unstable angina pectoris (UAP).

Methods: Patients of UAP were divided into two groups, the treated group (n = 60) was treated with TXLC and the Danshen group (n = 30) was treated with composite Danshen tablet. The plasma endothelin (ET) and calcitonin gene related peptide (CGRP) were measured before and after treatment.
