BACKGROUND:Anesthesia is a protective measure to animals in animal experiments, but the use of the corresponding anesthetic drugs wil have different effects on the experimental results.
OBJECTIVE:To analyze the differences of various indexes and the therapeutic effect ofmyocardial ischemia canine model of coronary stenosis under the condition of consciousness and anesthesia.
METHODS:Twenty Beagle canine myocardial ischemia models were equaly assigned to five groups, and prepared according to the complete orthogonal Latin square arrangement for the experiment. Intervention procedures included the normal observation (normal control for 10 minutes, observation for 30 minues), conscious model (after normal control, coronary artery stenosis for 10 minutes, and observation for 30 minutes), conscious treatment (after normal control, coronary artery stenosis for 10 minutes, 50 μg/kg nitroglycerin sublingualy buccal, and observation for 30 minutes), anesthesia model (animals received anesthesia; after normal control, coronary artery stenosis for 10 minutes, and observation for 30 minutes), anesthesia treatment (animals received anesthesia; after normal control, coronary artery stenosis for 10 minutes, 50 μg/kg nitroglycerin sublingualy buccal, and observation for 30 minutes). Werecorded canine electrocardiogram, blood pressure, heart rate and body temperature level when animals were conscious after coronary artery stenosis, and mean arterial blood pressure, body temperature, heart rate, electrocardiogram ST segment changes in conscious and anesthetic states in myocardial ischemia dogs, and observed the therapeutic effect of nitroglycerin on conscious and anesthetic states in myocardial ischemia dogs.
RESULTS AND CONCLUSION:The electrocardiogram, blood pressure, heart rate and body temperature were changed after the coronary artery stenosis in conscious dogs, and the ST segment of electrocardiogram was significantly increased. The blood pressure and heart rate were significantly higher than that in the conscious state (P< 0.05),and the ST segment of electrocardiogram in dogs was significantly increased in conscious and anesthetic states. After the treatment of nitroglycerin, the effect was obvious in the myocardial ischemia model in conscious state. The results showed that the model of myocardial ischemia and the clinical fitting degree were higher, which could reduce the effect of anesthesia on the experimental results.

Objective To explore the effect of Paclitaxel-Chitosan Sustain film on growth, apoptosis and cell cycle of biliary fibroblasts cells. Methods Human biliary fibroblasts cells were cultured and treated with PTX-CSF and naked PTX,separately, untreated cells as blank control. The experiment was divided into five groups:untreated group, simple PTX-treated group (250nM) and low, medium and high chitosan sustained-release film PTX-treated group (100 nM, 250 nM, 500 nM). The proliferations of cells were determined by MTT assay. The apoptosis and cell cycle of cells were detected by FCM. Results The proliferation of biliary fibroblasts cells was inhibited by PTX-CSF with time-dependent and dose-dependent, and the inhibiting effect was more obvious than naked PTX treatment as the time went on. Meanwhile, PTX-CSF could inhibit the magration of bile duct fibroblasts induced by TGF-β1,and had longer effect than naked PTX. After 72 h, the apoptosis rate of cells treated with PTX-CSF was significantly higher than cells treated with naked PTX or untreated cells(P<0.05), the difference between naked PTX or untreated cells was not significant. Compared with untreated cells, the proportion of G 2/M in cells treated with PTX or PTX-CSF were significantly increased, and the former was sinificantly higher than the latter(P<0.05). Conclusion Compared with naked PTX, PTX-CSF has strong cytotoxic effects and obviously sustained-release effect. The effective concentration can be maintain for a long time by PTX-CSF, and it could be as the novel drug delivery system to continuously inhibit proliferation of bile duct fibroblasts.
