AIM: To investigate the effects of fluvastatin on the airway remodeling in a guinea pig model of asthma. METHODS: Asthmatic guinea pig model was established by intraabdominal injection of ovalbumin and aluminium hydroxide and challenged with ovalbumin once every other day for 60 days. 30 guinea pigs were randomly divided into three groups: control group ( n= 10), asthma group ( n= 10) and fluvastatin plus asthma group ( n= 10) in which fluvastatin was inhaled at concentration of 0.5 g/L 30 min before every challenging. The thickness of airway smooth muscle layers of every three groups were compared after Haematin-Eosin staining by image analysis system. The level of ras mRNA in airway were examined by Dot-blot molecular hybridization. The expression levels of ras p21 were also examined by immunohistochemical technique. RESULTS: The mean thickness of airway smooth muscle in asthma group was (74 27?3 30) micrometer, greater than that of control group [(38 57?3 37) micrometer ( P

Objective To study the diagnostic evaluation of spiral CT for acute pulmonary embolism(PE).Methods 24 patients with PE were scanned with SCT(Philips AVEL.)pre-and post-injection of 100 ml contrast medium(Ultravist or Omnipaque 300 mgI/ml)from elbow vein.Enhanced CT scans were started after injection of 15 and 30 seconds respecting.Results The indirect signs on plain CT image were:lung-making sparse in 12 cases;lesion of pulmonary infarction in 11 cases;pulmonary hypertension signs in 3 cases;pleural thickening in 4 cases;pleural effusions in 8 cases.The direct signs on enhanced CT images were:Intraluminal filling defect (mural filling defect in 32 vessels;partial filling defect in 30 vessels;total occlusion in 92 vessels and central filling defect that was railway-track sign in 15 vessels)and smaller caliber of pulmonary artery in 14 vessels.Conclusion Enhanced pulmonary SCT angiography is the safe,quick and effective imagilogic examination for acute PE.

Objective To examine the localization of neurokinin B receptor (NK3)\|like immunoreactivity (\|LI) in the central nervous system of the mouse. Methods An immunohistochemcial staining method was used. Results NK3 receptor\|LI was localized in somatic and dendritic profiles in the most parts and in neuropil in a few regions of the mouse central nervous system. A large number of neurons with NK3\|LI was seen in the anterior olfactory nuclei, accumbens nucleus, septal area, ventral pallidum, pallidum, caudate putamen, nucleus of the stria terminalis, anterior hypothalamic area, tuber cincreum area, lateral hypothalamic area, perifornical nucleus, supraoptic nucleus, arcuate nucleus, mammillar nuclei, substatia nigra, ventral tegmental area, retrorubral area, superior and inferior colliculus, periaqueductal gray, nucleus of the solitary tract, and superficial layers of the medullary and spinal dorsal horns. The superfical layers of the cerebral cortex, piriform cortex, dorsal hippocampus, amygdal complex, reticular formation of the brainstem contained some neurons with NK3 receptor\|LI. In the ventral hippocampus, median and intralaminar nuclei of the thalamus and interpeduncular nuclei, NKR\|LI was localized in neuropil. Conclusion\ Neurons with NK3 receptor\|LI were widely distributed in the central nervous system. It may be involved in many physiological functions in the central nervous system of the mouse.\;[

Objective To investigate the effect of notch signaling pathway on drug resistance and invasiveness of bladder cancer .Methods We observed the changes of growth and morphology of bladder cancer T 24 , 5637 and J82 cells which treated for 48 hours using γ-secretase inhibitor by inverted microscope .The mRNA and protein lev-els of the EMT molecular markers , including E-cadherin , N-cadherin , vimentin and Alpha-smooth muscle actin were examined by RT-PCR and Western blot in bladder cancer cells;Detected the changes of drug resistance and invasion respectively by MTT and Transwell in bladder cancer cells .Results After completely blocking the Notch signaling pathway , the inverted microscope showed that bladder cancer cells became smaller and more disperse ;RT-PCR and Western blot showed the mRNA and protein levels of E-cadherin were up-regulated ( P<0.05 ) , contrast , N-cadherin , vimentin and Alpha-smooth muscle actin were down-regulated ( P<0.05 ); The prolifera-tion of bladder cancer cells were significantly inhibited by MTT test;The number of through microporous membrane cells significantly decreased ( P<0.05 ) shown by Transwell test .Conclusions The Notch signaling pathway is completely blocked that nhibites proliferation and EMT of bladder cancer cells , reduces drug resistance and inva-sion in bladder cancer cells .It suggests that drug resistance and invasiveness of bladder cancer can be changed through EMT which is regulated through notch signaling pathway .

ObjectiveTo evaluate the safety and superiority of dressings and bandage compression method for patients after percutaneous coronary intervention through femoral artery.MethodsA total of 648 patients who received percutaneous coronary intervention through femoral artery were randomly divided into three groups: the modified group (224 cases), the routine group (213 cases) and the haemostat group (211 cases), they each adopted modified dressings and bandage compression method, the traditional oppression hemostatic method, and arterial oppression with hemostat method. The unarmed oppression time, expenditure, braking time, and complications were observed and analyzed statistically.ResultsThere was no significant difference in braking time and local vascular complications of the three groups. Compared with the routine group, the modified group reduced the unarmed oppression time and the medical staffs workload; compared with the hemostat group, it reduced the expenditure.ConclusionsImproved dressings and bandage compression method can reduce the unarmed oppression time and expenditure, it is an ideal local hemostasis method for patients undergoing percutaneous coronary intervention through femoral artery, and is worthy of clinical application.

Objective To investigate the causes of pancreatic injury after autologous liver transplantation in rats. Methods Forty-two SD rats were randomly divided into post autologons liver transplantation 1-hour group, 6-hour group, 12-hour group, 24-hour group, 48-hour group, 72-hour group and sham group (6 rats per group). The plasma concentrations of amylase and lipase were measured to assess pancreatic exocrine function. The histomorphological changes of pancreatic tissue were studied under optical and electron microscopes. All data were analyzed via one-way ANOVA. Results The plasma concentrations of amylase and lipnse in post autologous liver transplantation 1-hour group were significantly higher than those in sham group, and they gradually increased as time passed by. The plasma concentrations of amylase and lipase reached peak at hour 48, after which they decreased gradually. There was a significant difference in the plasma concentration of amylase and lipase among the 7 groups (F = 538.622,489.417, P < 0.05). Acute edematous pancreatitis was observed 1 hour after autolognus liver transplantation, and acute hemorrhagic necrotic pancreatitis was observed 6 hours after transplantation. The degree of injury reached a peak 48 hours after transplantation. The number of mitochondria was increased, and endoplasmic reticulum and Golgi apparatus were swollen 1 hour after transplantation, and the area, perimeter, specific surface area and mean gray value of mitochondria were (312±40) mm~2, (80.3±3.8)mm, 0.332±0.039 and 113±11, respectively. As time passed by, the injury of the pancreatic cells was aggravated and autophagosomes were observed. The injury was most severe 48 hours after transplantation, and the area, perimeter, specific surface area and mean gray value of mitochondria were (466±7) mm~2, (108.8±3.7) mm, 0.298±0.009 and 195±12, respectively. There were significant differences in the specific surface area and mean gray value among all the groups (F = 9.322, 76.560, P < 0.05). Conclusion The pancreatic injury after autologous liver transplantation is related to the energy metabolism of the pancreatic cells induced by hypoxia.
