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 discuss the best resistance factors of paclitaxel(Taxinol)on benign biliary scar fibrosis,in order to provide an effective basis for clinical prevention and treatment of benign biliary scar fibrosis.Methods Human bile duct epithelial cells were cultured in vitro,the prepared PTX at 0.001 uM,0.005 uM,0.1 uM,0.5 uMand 1 uMconcentration were separately added into cells for 48 h.The half inhibitory rate of BEC (IC50) were determined by MTT and the optimal concentration were confirmed.Human bile duct epithelial cells were cultured in 0 h,24 h,48 h and 72 h,the inhibitory rate of BEC at 100 nM,250 nM,and 500 nM PTX-Chitosan Sustained release membranes and the optimal concentration of PTX were determined by MTT and the optimal concentration of PTX-SRM were obtained.Human bile duct epithelial cells were cultured for 48 h and 72 h,the mRNA and protein expression ofα-SMA,E-cadherin,Vimentin were detected by Western Blot and Real-time PCR methods.Results The optimum resistance concentration of PTX to benign biliary scar was 250 nM.PTX and PTX-SRM could effectively inhibit the proliferation and transformation of BEC,and the best effective treatments to resist benign biliary scar fibrosis were low and middle concentrations of PTX-SRM,the best drug loading were 100 nMand 250 nM.The inhibition duration of PTX-SRMon BEC was longer than PTX alone(P<0.05).Conclusion The inhibition of PTX-SRMon BEC proliferation and transformation is better than the single drug of PTX,which provides a new scientific and feasible method for clinical prevention and treatment of benign biliary scar.

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.

OBJECTIVE To investigate the distribution scope of the pan-drug resistant bacteria in the SICU patients including their producing environment and high risk factors in these two years and to approach its prevention and treatment policy. METHODS The distribution scope and the high risk factors of the pan-drug resistant bacteria in SICU were reviewed and analyzed from Jan 2005 to Jan 2007.RESULTS There were 11 cases in the period from Jan 2005 to Jan 2006; and was only 1 case from Jan 2006 to Jan 2007. CONCLUSIONS To establish the drug resistance monitoring system, attach great importance to isolation and education, to monitor the original region of the pan-drug resistant bacteria, and to adopt the comprehensive antibiotic policy to control the drug resistant bacteria. Among them, the early effective isolation of high risk patients may be very effective to reduce the producing and developing of the pan-drug resistant bacteria.

Objective To investigate the effect of antisense telomerase reverse transcriptase (TERT) on 5-hydroxytryptamine (5-HT) induced proliferation and cell cycle of pulmonary artery smooth muscle cells (PASMCs). Methods PASMCs were cultured and divided into four groups: control group (cultured in RPMI-1640 culture medium), 5-HT group (cultured in culture medium containing 5-HT), antisense oligonucleotide (ASODN) group (cultured in culture medium containing 5-HT and ASODN TERT), and sense oligonucleotide (SODN) group (cultured in culture medium containing 5-HT and SODN TERT). The apoptosis of PASMC was observed by fluorescence microscopy with Hoechst staining. Apoptosis and cell cycle was analyzed with flow cytometry. Expression of proliferated cell nuclear antigen (PCNA) was determined by immunohistochemistry staining. Results Hoechst staining showed that apoptosis in 5-HT group (161?33) was significantly higher than that in control group (63?16, P

OBJECTIVE To summarize the clinical characteristics,diagnositic and therapeutic strategies of severe cytomegaloviral (CMV) pneumonia after kidney transplantation. METHODS To analyze retrospectively pertinent clinical information of 6 cases of severe cytomegaloviral pneumonia after kidney transplantation, including developing process of disease, clinical manifestation of pre-and post-hospitalization ,various assistant examination,therapeutic procedures and prognosis. RESULTS 6 cases had similar characters of episode as follows:CMV pneumonia occurred after 1～3 months after kidney transplantation. Major clinical symptoms included fever, coughing,few sputum without obvious manifestation of breathholding.Peripheral white blood cell was normal or less than normal range, serum CMVpp65 was finally positive during hospital stay. Radiological image of the lung presented inflammatory infiltration and obvious interstitial lesion after 7～10 days of fever, which went worse rapidly. Renal function descended with deterioration of pulmonary infection. All of patients had been treated with multiple antibiotics,glucocorticoid and mechanical ventilation, Etiological diagnosis of the 3th～6th cases were earlier than 1th～2th cases , the 3th～6th cases who finally survived were treated with longer and higher doses of antivirus and glucocorticoid, than 1th～2th cases who died of refractory hypoxemia and acute renal failure during hospital stay. CONCLUSIONS Severe cytomegaloviral pneumonia had similar clinical characteristics of episode. early diagnosis of etiology,continuous application of antivirus and glucocorticoid were crucial for Severe cytomegaloviral pneumonia after kidney transplantation.
