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. The most frequent manifestation is bronchial infammation and suppuration with or without bronchiectasis. Bronchoalveolar lavage fndings show an increased percentage of neutrophils. Drug-related pulmonary abnormalities include disorders which are directly induced by sulfasalazine, mesalamine and methotrexate, and opportunistic lung infections due to immunosuppressive treatment. In most patients, the development of pulmonary disease parallels that of intestinal disease activity. Although infrequent, clinicians dealing with CD must be aware of these, sometimes life-threatening, conditions to avoid further impairment of health status and to alleviate patient symptoms by prompt recognition and treatment. The treatment of CD-related respiratory disorders depends on the specific pattern of involvement, and in most patients, steroids are required in the initial management. © 2014 Baishideng Publishing Group Co., Limited.

To explore a potential methodology for treating aganglionic megacolon, neural stem cells (NSCs) expressing engineered endothelin receptor type B (EDNRB) and glial cell-derived neurotrophic factor (GDNF) genes were transplanted into the aganglionic megacolon mice. After transplantation, the regeneration of neurons in the colon tissue was observed, and expression levels of differentiation-related genes were determined. Primary culture of NSCs was obtained from the cortex of postnatal mouse brain and infected with recombinant adenovirus expressing EDNRB and GDNF genes. The mouse model of aganglionic megacolon was developed by treating the colon tissue with 0.5 % benzalkonium chloride (BAC) to selectively remove the myenteric nerve plexus that resembles the pathological changes in the human congenital megacolon. The NSCs stably expressing the EDNRB and GDNF genes were transplanted into the benzalkonium chloride-induced mouse aganglionic colon. Survival and differentiation of the implanted stem cells were assessed after transplantation. Results showed that the EDNRB and GDNF genes were able to be expressed in primary culture of NSCs by adenovirus infection. One week after implantation, grafted NSCs survived and differentiated into neurons. Compared to the controls, elevated expression of EDNRB and GDNF was determined in BAC-induced aganglionic megacolon mice with partially improved intestinal function. Those founding indicated that the genes transfected into NSCs were expressed in vivo after transplantation. Also, this study provided favorable support for the therapeutic potential of multiple gene-modified NSC transplantation to treat Hirschsprung's disease, a congenital disorder of the colon in which ganglion cells are absent. © 2013 Springer Science+Business Media New York.

Purpose: To develop PEGylated multi-walled carbon nanotubes as a sustained release drug delivery system. Methods: Oxaliplatin was incorporated into inner cavity of PEGylated multi-walled carbon nanotubes (MWCNT-PEG) using nano-extraction. Oxaliplatin release rates from MWCNT-PEG-Oxaliplatin were investigated using dialysis tubing. Cytotoxicity of oxaliplatin, MWCNT-Oxaliplatin and MWCNT-PEG-Oxaliplatin were evaluated in HT29 cell by MTT assay, Pt-DNA adducts formation, γ-H2AX formation and cell apoptosis assay. Results: Loading of oxaliplatin into MWCNT-PEG was ~43.6%. Sustained release occurred to MWCNT-PEG-Oxaliplatin, with only 34% of oxaliplatin released into medium within 6 h. In MTT assay, MWCNT-PEG-Oxaliplatin showed slightly decreased cytotoxic effect when cell viability was assessed at 12 and 24 h. A drastic increase of cytotoxicity was found when cell viability was assessed at 48 and 96 h. Pt-DNA adducts formation, γ-H2AX formation and cell apoptosis assay results showed the same trend as the MTT assay, suggesting sustained-release for MWCNT-Oxaliplatin and MWCNT-PEG-Oxaliplatin formulations. Conclusions: PEGylated multi-walled carbon nanotubes can be used as sustained release drug delivery system, thus remarkably improving cytotoxicity of oxaliplatin on HT-29 cells. © 2012 Springer Science+Business Media, LLC.

Extraintestinal manifestations of inflammatory bowel disease (IBD) are a systemic illness that may affect up to half of all patients. Among the extraintestinal manifestations of IBD, those involving the lungs are relatively rare and often overlooked. However, there is a wide array of such manifestations, spanning from airway disease to lung parenchymal disease, thromboembolic disease, pleural disease, enteric-pulmonary fistulas, pulmonary function test abnormalities, and adverse drug reactions. The spectrum of IBD manifestations in the chest is broad, and the manifestations may mimic other diseases. Although infrequent, physicians dealing with IBD must be aware of these conditions, which are sometimes life-threatening, to avoid further health impairment of the patients and to alleviate their symptoms by prompt recognition and treatment. Knowledge of these manifestations in conjunction with pertinent clinical data is essential for establishing the correct diagnosis and treatment. The treatment of IBD-related respiratory disorders depends on the specific pattern of involvement, and in most patients, steroids are required in the initial management. Corticosteroids, both systemic and aerosolized, are the mainstay therapeutic approach, while antibiotics must also be administered in the case of infectious and suppurative processes, whose sequelae sometimes require surgical intervention. © 2014 Baishideng Publishing Group Inc.

Objective: Factors impacting surgical options and outcomes in patients with cervical ossification of the posterior longitudinal ligament (OPLL) were explored. Methods: A retrospective analysis was conducted of 127 eligible cervical OPLL patients (61 males, 66 females) aged 41-70 years (mean 55.2 years) selected from 152 total OPLL patients treated from 2002 to 2006, with 5-10-year (mean 6.8 years) follow-up. Patients underwent anterior subtotal corpectomy with ossification ligament resection (anterior surgery, n = 68) or posterior cervical double-door laminoplasty (posterior surgery, n = 59). Radiographic assessments of cervical curvature, T2-weighted MRI (MRIT2) signal, and OPLL occupying ratio were correlated with surgical strategy before surgery and at 1, 5 weeks, and 5 years. Results: Lordosis increased following anterior surgery, though kyphosis improved by 10.3 %. The canal stenosis occupying ratio was >50 %, and short-term improvement following anterior surgery was significantly higher than posterior surgery (P > 0.0001). Superior neurological function was observed in patients with unchanged versus high spinal MRIT2 signals (P = 0.0434). No significant differences were observed in short-term outcomes between anterior and posterior surgeries in high spinal MRIT2 signal patients, but anterior surgery produced significantly better long-term outcomes at 1 week (P = 0.7564) and 1 year (P = 0.0071). Complications occurred in five anterior and three posterior surgeries. Conclusion: Preoperative assessment of cervical curvature, MRIT2 signal, and occupying ratio can be used to guide clinical surgical approach selection to potentially produce better long-term outcomes in patients with OPLL. © 2013 Springer-Verlag Berlin Heidelberg.

To investigate the effects of n-3 polyunsaturated fatty acids(n-3PUFA) on human colorectal cancer cell line HT-29 and associated mechanism. The effects of docosahexaenoic acid (DHA) on the proliferation and apoptosis on HT-29 human colorectal cancer cells were evaluated by MTT assay, cell morphology (Hoechst33258 dyeing), DNA gel electrophoresis, and flow cytometry. The content of n-6PUFA and n-3PUFA of the treated cells and the ratio of n-6/n-3PUFA were analyzed by chromatography. DHA effectively inhibited HT-29 cell proliferation in a dose- and time-dependent manner. The proliferative inhibition rates of HT-29 cells treated with 10, 20, 40, and 80 mg/L DHA for 24 hours were 16.8%, 24.7%, 50.0%, and 60.1%, respectively, while the inhibition rates were 50.0%, 69.9%, and 77.0% respectively when HT-29 cells were treated with 40 mg/L DHA for 24, 48, and 72 hours. The typical apoptotic morphologic changes of HT-29 cells could be observed, including chromatin margination, nuclear condensation and apoptotic bodies. Gel electrophoresis of DNA degradation displayed typical DNA ladder fragments. HT-29 cells treated with DHA were arrested in G1 phase and the proportion of HT-29 cells in Gl phase increased compared with that of the control group (72.1% vs. 51.3%) while the proportion of the cells in S phase decreased significantly (19.9% vs. 38.9%). The content of n-6PUFA decreased, n-3PUFA content increased and the ratio of n-6/n-3PUFA lowered significantly in colorectal cancer cells treated with DHA (P<0.01). n-3PUFA can inhibit the growth of human colorectal cancer cells via inhibition of the proliferation and induction of apoptosis. These effects may be associated with decrease in n-6/n-3PUFA ratio.

Background: Despite the presence of glucagon-like peptide-1 receptor (GLP-1R) in kidney tissues, its direct effect on diabetic nephropathy remains unclear. The transforming growth factor-β1(TGF- β1) and the connective tissue growth factor (CTGF) both induce extracellular matrix accumulation and persistent fibrosis in the glomerular mesangium of patients with diabetic nephropathy. Objective: Herein, we demonstrate that a GLP-1R agonist, exendin-4, exerts renoprotective effects through its influence on TGF-β1and CTGF in human mesangial cells (HMCs), cultured in a high glucose medium. Method: HMCs, cultured in a high glucose medium, were used for the current study. The direct effect of exendin-4 on TGF-β1and CTGF expression was confirmed in HMCs. MDL-12330A (a specific adenylate cyclase inhibitor) and PKI14-22 (a protein kinase A inhibitor) were used to examine the role of the cAMP signaling pathway in exendin's anti-fibrosis action. Results: The findings showed that exendin-4 inhibited the proliferation of HMCs, and upregulated the expression of TGF-β1and CTGF, induced by high glucose. The effect of exendin-4 is largely dependent on the activation of adenylate cyclase. Conclusion: This study provides new evidence that GLP-1 acts as an antifibrotic agent in HMCs. Copyright © 2012 S.

Purpose: Nutritional status has been associated with long-time outcomes in cancer patients. We investigated whether the prognostic nutritional index (PNI), an indicator of nutritional status, affects overall survival in patients with malignant pleural mesothelioma (MPM). Methods: We enrolled 121 patients with histologically confirmed MPM, who had successfully undergone biopsy by medical thoracoscopy in this study. Demographic, clinical and laboratory data were collected retrospectively. The PNI was calculated as 10× serum albumin value (g/dl) + 0.005 × total lymphocyte count (per mm3) in peripheral blood. Univariate and multivariate analyses were used to identify prognostic factors. Results: Mean pretreatment PNI was 44.6. PNI was significantly associated with age (P = 0.031), smoking habits (P = 0.039) and weight loss (P = 0.029). Survival analysis showed PNI to be an independent prognostic factor in MPM. Patients with lower PNIs (PNI < 44.6) had greater risk of death than those with higher PNIs (PNI ≥ 44.6; hazard ratio: 2.290; 95 % confidence interval: 1.415-3.706; P = 0.001). These analyses were adjusted for patient age, gender, smoking habits, dyspnea, chest pain, weight loss, primary site of tumor, histology, platinum-based systemic chemotherapy, hospital and stage. Conclusions: Pretreatment PNI is a novel independent prognostic factor in MPM. © 2013 Springer-Verlag Berlin Heidelberg.

Although gemcitabine-based chemotherapy is one of the more effective chemotherapy regimens against NSCLC, there are still many patients who do not benefit from this therapy. The mechanism of initial or acquired resistance to gemcitabine chemotherapy remains unknown. In this study, we investigated the protein profiling in gemcitabine-resistant and gemcitabine-sensitive NSCLC cell lines by a proteomic technology in order to identify novel gemcitabine resistance associated biomarkers for NSCLC patients. The proteomic profiling of NSCLC cell line H460 and its gemcitabine-resistant subline H460/GEM were compared by an isotope-coded affinity tag technology and tandem mass spectrometry. We further validated the expression of sorcin, a gemcitabine-resistance-related protein identified by proteomics, in 62 NSCLC specimens by immunohistochemistry. Fourteen gemcitabine resistance-related proteins were identified including nine upregulated proteins and five down-regulated proteins. Immunohistochemical results demonstrated that sorcin staining was seen in 66.1% of NSCLC tumors, and sorcin overexpression was associated with gemcitabine resistance and a poor prognosis in NSCLC patients. In conclusion, sorcin might play an important role in the resistibility to gemcitabine, and it could also be a novel candidate biomarker for predicting the response of NSCLC patients to gemcitabine treatment. © Springer Science+Business Media, LLC 2009.

To explore the effects of Jingui Shenqi Pill (JSP) on the testis telomerase activity in mice of Shen-yang deficiency syndrome (SYDS). The SYDS model was prepared in 30 mice by over-fatigue and sexual overstrain. They were randomly divided into the model group and the JSP group, 15 in each group. Another 15 normal male mice were selected as the normal group. Mice in the normal group were fed routinely, with distilled water administered intragastrically at the daily dose of 0.1 mL/10 g. Mice in the model group were also administered intragastrically with distilled water at the daily dose of 0.1 mL/10 g while modeling establishment. Mice in the treatment group were administered intragastrically with JSP suspension at 0.1 mL/10 g (the concentration was 0.241 g/mL). The intervention lasted for 4 weeks. Four weeks later, the testis telomerase activity was detected in the three groups by ELISA. The SYDS model was replicated successfully by over-fatigue and sexual overstrain. JSP could improve the signs of mice of SYDS. Compared with the normal group, the activity of testis telomerase decreased in the model group (P < 0.01). Compared with the model group, the testis telomerase activity markedly increased in the treatment group (P < 0.01). The testis telomerase activity in mice of SYDS caused by over-fatigue and sexual overstrain obviously decreased, when compared with that in mice of the normal group. JSP could recover its activity.
