Objective To investigate the effets of three mood stabilizers on ouabain?induced ERK1/2 phosphorylation in astrocytes. Methods As?trocytes were treated with different agents and divided into different groups accordingly,namely,the control group with saline,the group with oua?bain,the group with mood stabilizers(lithium carbonate,carbamazepine,sodium valproate)and the group with ouabain+mood stabilizers. The phosphorylation of ERK1/2 in each group was analyzed by Western blot. Results Compared with saline and mood stabilizer groups,the phosphoryla?tion of ERK1/2 was increased in the ouabain group,with statistical significance(P<0.05). There was no significant difference in ERK1/2 phosphoryla?tion between the group with ouabain+mood stabilizers and the control or mood stabilizer group. Conclusion The three kinds of mood stabilizers can inhibit ouabain?induced ERK1/2 phosphorylation in astrocytes.

ObjectiveTo analyze the relationship between pancreatic cancer (PC) and diabetes mellitus (DM),and the clinical and pathological features of pancreatic cancer in patients with DM.MethodsFrom January,2008 to December,2010,151 patients with PC and 195 comparable patients without PC were enrolled in a case-control study to analyze the relationship between PC and DM.ResultsThe OR was 5.91 (95％ CI 3.03-8.00,P＜0.05) in PC patients with DM for less than 2 years,and 1.308 (95％ CI 0.37-4.60,P＞0.05) in patients with DM for 2 to 5 years,and 1.16(95％ CI 0.44-3.19,P＞0.05) for patients with DM for more than 5 years.There was no significant difference between PC patients with and without DM in gender,age,body-mass index (BMD,obstructive jaundice,tumour location and tumour metastases (P＞0.05).ConclusionsThere was a significant correlation between PC and DM.De novo DM may be a clinical manifestation in patients with PC.PC patients with concurrent DM have no particular clinical and pathological features.

AIM: To study the protective effects of basic fibroblast growth factor (bFGF) on myocardial ischemia in rats and their underlying mechanism. METHODS: A rat myocardial ischemic injury model was established by left coronary artery ligation. The rats were killed at 2 h, 4 h, 8 h after coronary artery occlusion. The samples of blood and myocardium were collected for observing the expression of Bcl-2 and Bax in myocardial cells and the changes of superoxide dismutase (SOD) or myocardial enzymes. RESULTS: The amount of Bcl-2 protein expression of myocardial cells in ischemia + bFGF group was significantly higher than that in ischemia+saline group (P

Background and purpose: It has been demonstrated that cyclooxygenase-2 (COX-2) is over-expressed in some subtypes of non-Hodgkin’s lymphoma (NHL), and COX-2 correlates with the expression of P-glycoprotein and Bcl-2, which may contribute to chemotherapy-resistance in NHL. The purpose of this study was to investigate the expression of COX-2 in B-cell lymphoma cell lines and the potential mechanisms of celecoxib, a selective COX-2 inhibitor, to sensitize lymphoma cell lines to epirubicin. Methods: Quantitative fluorescent real-time poly-chain-reaction (qRT-PCR) and Western blot were employed to determine the expression of COX-2 in Raji, Jeko-1 and Namalwa cell lines, as well as in peripheral blood B cells from normal controls. Cell lines were treated with celecoxib at gradient concentrations, followed by the detection of cell viabilities by cell counting kit-8 (CCK-8).Meanwhile, the changes in expression of MDR-1 mRNA and Bcl-2 mRNA before and after celecoxib treatment were determined by qRT-PCR. Raji cells were treated with epirubicin alone or in combination with gradient concentrations of celecoxib for 72 h, then CCK-8 was used to analyze whether celecoxib sensitize Raji cells to epirubicin. Results:Neither lymphoma cell lines nor normal B cells expressed detectable COX-2 in this study. Celecoxib inhibited the proliferation of the 3 lymphoma cell lines, and the mRNA expressions of MDR-1 and Bcl-2 were decreased by celecoxib in a concentration-dependent manner, except for that MDR-1 was undetectable in Jeko-1 cells. In addition, celecoxib sensitized Raji cells to epirubicin, indicating a synergistic anti-tumor effect between the two agents. Conclusion:Selective COX-2 inhibitor celecoxib down-regulates the expressions of MDR-1 mRNA and Bcl-2 mRNA in B-cell-originated lymphoma cell lines, and sensitizes Raji cells to epirubicin.

OBJECTIVE To investigate the effect of subcutaneousimmunotherapy(SCIT) on levels of the serum human beta defensin-2 in children with allergic rhinitis. METHODS 30 cases of children with allergic rhinitis who were treated by SIT were selected as the treatment group, 20 cases of healthy children as the control group. Serum HBD-2 concentration of the control group was tested. Serum HBD-2 concentration of the treatment group was tested at three different time points: before SCIT, half a year after SCIT and one year after SCIT. And total nasal symptom scores(TNSS) and medication scores were recorded at each time point. RESULTS The serum HBD-2 concentration of the control group, that of the treatment group before SIT, half a year after SIT and one year after SIT were 4.62[4.08; 4.87], 3.74[3.37; 4.61], 4.62[4.13; 5.54], 4.79[4.45;6.19]ng/ml. The HBD-2 concentration gradually increased after SCIT. The TNSS of the treatment group before SCIT, half a year after SCIT and one year after SCIT were 7.43±2.15, 4.17±2.16, 4.20±1.92, The medication scores of the treatment group before SCIT, half a year after SCIT and one year after SCIT were 1.25[0.75; 1.38], 0.25[0; 0.75, 0.25[0; 0.75].There was no correlation (all P>0.05) between the serum HBD-2 concentration and TNSS or medication scores of the treatment group. CONCLUSION The serum levels of HBD-2 in patients with allergic rhinitis were lower than those in normal persons. The specific immunotherapy raised the serum HBD-2 levels of allergic rhinitis patients.

OBJECTIVE: To compare the results of supracricoid partial laryngectomy-cricohyoidopexy (SCPL-CHP) and horizontal-vertical hemilaryngectomy in the treatment of mid and late laryngeal carcinoma. METHOD: Retrospective analysis on the types of mid and late stage of laryngeal carcinoma clinical material, 22 patients supracricoid partial laryngectomy-cricohyoidopexy, 20 patients horizontal-vertical hemilaryngectomy, each with the added radiotherapy. The long term results of operation and glottic reconstruction were evaluated by postoperative visiting, semi-quantitative speech intelligibility analysis, electroglottograph (EGG) and so on. RESULT: Forty-two cases of laryngeal cancer patients were decannulated, the decannulation rate was 100%. Postoperative decannulation time: surgical CHP for (44.0 +/- 4.6) d, 3/4 throat operation for (39.0 +/- 2.7) d, two groups of postoperative decannulation time difference was statistically significant (t = 4.2395, P < 0.01). Eight weeks after evaluation, two groups's swallowing function and postoperative evaluation of patients after one year speech intelligibility difference was not statistically significant (P > 0.05). GRBAS in the evaluation of G rating, the difference between the two groups was statistically significant (P < 0.05), CHP group showed,for most patients, a severe hoarse degree, but 3/4 throat operation group mainly represented a moderate degree lever. EGG parameters were checked after 1 years. F0 comparative differences was not statistically significant (P > 0.05), and the jitter, shimmer and NNE compared CHP group to 3/4 laryngectomy group were significantly increased (P < 0.05). Kaplan-Meier method statistics show: CHP group and 3/4 laryngectomy group 3 years and 5 year accumulate survival rates were 95.5% and 89.7%, 85.1% and 83.7% respectively, two groups of three, five years of survival difference was not statistically significant (P > 0.05). CONCLUSION According to the laryngeal of middle-late carcinoma, the region and the involvement of the scope were considered to choose appropriate surgical treatments, and both can complete resection of the tumor, and can retain good laryngeal functions,and CHP has a wider range of operation indications and clinical application prospect, is worthy to be popularized.

Bats are important reservoir animals and more than 60 viruses have been identified in bats with many of them highly pathogenic to human. In order to understand the natural background, genetic diversity of bat viruses in China and discover potential viral pathogens, Solexa sequencing based viral metagenomics focusing on bats tissues was established and to analyze the virome of bats collected from Jilin, Yunnan and Hunan province. By Solexa sequencing, 116 442 324 useful reads were obtained and assembled into 4 872 contigs, of which 8.2% (4 002/4 4872) were annotated to 36 viral families, including 19 vertebrate virus families, 6 plant virus families, 4 insect virus families and 4 phages. Further contigs analyses showed that some adenovirus, bocavirus, picobirnavirus, parvovirus contigs sequences were similar with known viruses. However, part of them shared limited identities to these viruses implying the discovery of new viruses. Moreover, PCR validation of adenovirus and bocavirus confirmed the results obtained by viral metagenomics. This study aimed to understand bat virome in China by viral metagenomics and could be helpful to establish effective surveillance on wildlife-associate zoonoses.
