Glucagon-like peptide 1(GLP-1) is an important member of incretin.Takingitoralymay stimulate the terminal ileum and colon L cel s to secrete GLP-1. After GLP-1 biding specific receptor GLP-1 receptor ( GLP-1R), it exerts the roles of promoting glucose-dependent insulin secretion, inhibiting glucagon secretion, and decreasing plasma glucagon level. The molecular mass of GLP-1 is relatively smal er and can directly cross the blood-brain barrier, and both central and peripheral nervous systems have the GLP-1R expression. GLP-1 significantly improves neurological deficits and reduces infarct volume. It may exert neuroprotective effect through the mechanisms of inhibiting the inflammatory response, oxidative stress, and cel apoptosis. This article review s the discovery of GLP-1, its biological characteristics and neuroprotective effect in cerebral ischemia.

Objective:To retrospectively analyze the survival outcomes of the surgical management of primary small cell carcino-ma of the esophagus. Methods:The medical records were reviewed for patients diagnosed with esophageal carcinoma and underwent esophagectomy from January 2000 to December 2009 at the Department of Thoracic Surgery of the Henan Cancer Hospital. We fo-cused on the clinical data of patients with small cell carcinoma of the esophagus. The Kaplan-Meier approach with log-rank test was used for survival analysis. Results:A total of 5,062 patients underwent esophagectomy with curative intent at the Department of Thorac-ic Surgery of the Henan Cancer Hospital;among which, 57 (1.1%) were diagnosed with small cell carcinoma of esophagus. The most common surgical approach was trans-left thoracic incision esophagectomy. Cervical esophagogastrostomy was performed for all pa-tients. The most common chemotherapy regimen was EP. The overall 5-year survival rate was 12.5%, and the median survival time was 45 months. Among the various stages, the 5-year survival rate and survival time were 25% and 50 months for Stage I, 5.9% and 43 months for Stage II, and 4.3%and 43 months for StageⅢ. Subgroup analysis showed that cases treated with surgery alone had poorer overall median survival time compared with those cases that underwent surgery plus chemotherapy (23.2 months vs. 60.7 months, re-spectively;P<0.01). Even for Stage I patients, thesurgery plus chemotherapysubgroup was associated with a significantly longer me-dian survival time than the surgery alone subgroup (81.9 months vs. 22.3 months, P<0.01). Conclusion:For patients with primary small cell carcinoma of the esophagus, surgery alone cannot provide the optimal prognosis. Surgery combined with systemic chemother-apy can improve the survival time.

Objective To explore the effect of bone marrow mesenchymal stem cells (MSCs) on LPS-stimulated BV2 microglia in inflammatory reaction. Methods Mouse MSCs were isolated and purified by adherence screening. The routinely cultured BV2 microglia in vitro were divided into PBS control group (group A),PBS plus MSCs treatment group(group B),LPS stimulation group(group C) and LPS plus MSCs group(group D).MSCs and BV2 microglia were cultured in the transwell co-culture system for 24 hours. We observed BV2 microglia morphological changes under the microscope,detected the concentrations of NO by Griess reaction,and the level of IL-1β,TNF-αby ELISA. Results MSCs can improve the morphology of activated microglia. The concentrations of TNF-a, IL-1βand N0 in culture supernatants were increased significantly (P < 0.05) after microglia activation, however, at the present of MSCs,the concentration of these inflammatory factors declined dramaticly (P<0.05). Conclusions MSCs can significantly inhibit the activation of microglia. It may play a neuroprotective effect by reducing the inflammation of microglia. MSCs showing anti-inflammatory effects through non-direct contact with nicroglial, suggesting that MSCs outside the brain may also inhibit the activation of microglia.
