AIM: To investigate the role of endothelin-1 (ET-1), endothelin A receptor (ETAR) in pathophysiology of the lung after mustard intoxication. METHODS: The changes of transcription and expression of ET-1 and ETAR in the lung and their relationship with the tissue damage were studied with immunohistochemistry and RT-PCR. RESULTS: The level of ET-1 in the lung was significantly increased at 2 h, but decreased at 12 h after mustard intoxication. The transcription and expressin of ET-1 and ETAR were significantly increased at the early stage after intoxication. mRNA of endothelin-1 was increased, while mRNA of endothelin A receptor was down-regulated after (12 h.) CONCLUSION: ET-1 and ETAR in lung may play important roles in the pathophysiological process of mustard intoxication. [

Objective To investigate the effect of empowerment education on self-management in patients with diabetes mellitus. Methods A total of 128 patients with diabetes mellitus who met the criteria of WHO in 1999 were selected and divided into the control group(62 cases)and the observation group(66 cases). The control group accepted the traditional nursing methods, and the observation group accepted the empowerment education model. FBG, PBG, HbA1c and Diabetes Management Self-efficacy Scale (C-DMSES) were compared between two groups of patients after 3 months and 6 months. Results After the intervention with the empowerment education model, the patient′s FBG, PBG, HBA1c of the control group were (7.69±4.21) mmol/L, (11.78±3.21) mmol/L, (7.95±1.46)%three months after discharge, and (7.21 ± 3.19) mmol/L, (10.48 ± 4.65) mmol/L, (9.15 ± 2.36)% six months after discharge; while in the observation group, FBG, PBG, HBA1c were (6.23 ± 3.59) mmol/L,(9.32 ± 4.06) mmol/L, (6.69 ± 1.10)%three months after discharge, and (6.15 ± 1.89) mmol/L,(7.33 ± 2.10) mmol/L,(6.02 ± 2.17)%. The differences between two groups were significant (t=2.012-5.196, P<0.05). C-DMSES scores of the control group were 103.48 ± 18.41, 134.38 ± 13.01 on admission and six months after discharge, while in the observation they were 102.83 ± 10.91,157.64 ± 19.56. The differences between two groups were significant (t=3.151, P<0.05). Conclusions Empowerment education model can improve the ability of self-management of diabetes patients, improve self-efficacy to improve their own ability to control blood glucose.

Articles, reviews and proceeding papers published from 2012 to 2015 in medical, chemical and physical journals with the highest IF were retrieved from 2014 JCR and analyzed using the BICOMB software to generate the co-occurrence matrix of authors and plot the map of co-authorship network in medical, chemical and physical fields using the UCINET software.The correlation between the parameters for assessing the importance of co-au-thorship network nodes ( degree centrality, betweenness centrality, closeness centrality, eigenvector centrality) and biblimetric parameters of authors ( number of published papers, frequency of cited papers) was analyzed using the SPSS, which showed that degree centrality, betweenness centrality, and eigenvector centrality were positively corre-lated with the number of published papers and the frequency of cited papers whereas betweenness centrality was negatively correlated the number of published papers and the frequency of cited papers.Betweenness centrality was more significantly correlated with the number of published papers whereas degree centrality was more significantly correlated with the frequency of cited papers.
