ObjectiveTo investigate the anti-inflammatory mechanism of sodium aescinate in preventing postoperative intestinal adhesion in rats.
MethodsThe SD rats were subjected to operation for establishing intestinal adhesion models, then randomly divided into model group, dexamethasone group(dexamethasone, i.v. 5 mg/kg), and sodium aescinate group(sodium aescinate, i.v. 2 mg/kg), 10 rats in each group. Another ten normal rats were selected as sham operation group. One times administration was administered on day 1 before establishing adhesion model, and administration for 3 d after modeling, once a day. On day 7 after operation, all of the rats were killed. The intestinal adhesion was graded and the adhesive tissues were taken for hydroxyproline determination. The levels of tumor necrosis factor(TNF)-α, interleukin(IL)-1β, and IL-6 in the serum were detected by ELISA.
ResultsCompared with the model group, sodium aescinate could obviously improve the severity of postoperative adhesion, markedly decrease hydroxyproline content in the adhesive tissues(P < 0.01), and significantly inhibit the levels of TNF-α, IL-1β, and IL-6 in the serum(P < 0.01).
ConclusionSodium aescinate could effectively prevent the formation of postoperative intestinal adhesion by inhibiting the expressions of inflammatory cytokines and decreasing the inflammatory response.
ObjectiveTo investigate the awareness situation on the ARRIVE guideline and the Gold Standard Publication Checklist (GSPC) of animal experiments in researchers in animal experiments field in Lanzhou city, in order to improve the promotion of the two reporting guidelines in China.
MethodsA self-designed questionnaire was used to investigate the clinical graduate students and teachers in medical college in Lanzhou city. The investigation contents mainly included the basic information of the respondents, the awareness situation on the ARRIVE guideline, GSPC and other medical reporting guidelines. SPSS 21.0 software was used for data analysis.
ResultsA total of 329 questionnaires (40 were from teachers and 289 were from graduate students) were issued, of which, 287 questionnaires were effective. The results showed that the awareness rate on the ARRIVE guideline and GSPC in clinical graduate students and teachers in medical college in Lanzhou city were 11.8% and 12.5%, respectively, and there was no significant difference between students and teachers in awareness rate (P=0.903). The survey approaches, the age, education, job, and the organization of the respondents were all not the influence factors of awareness rate (P>0.05). The respondents knew about the reporting guidelines mainly through the website (33.4%), related studies (21.2%) and academic reports (17.4%).
ConclusionThe awareness rate on the ARRIVE guideline and GSPC is relative low in researchers in animal experiments field in Lanzhou city, and it needed to take purposeful measures to promote and popularize them.
