Objective To investigate the values of computed tomography(CT) and endoscopic retrograde cholangiopanc reatography(ERCP) in acute biliary tract obstruction associated with Clonorchiasis. Methods The image features of 47 patients with acute biliary tract obstruction associated with Clonorchiasis proved by operation (27 cases) and ERCP (20 cases) were reviewed retrospectively. Results Fourty-three cases showed equal intrahepatic bile duct diffuse dilatation from porta hepatis to capusle with different levels in CT, and 39 cases showed extrahepatic bile duct dilatation. There was no significant relationship for the extent of intra and extrahepatic bile duct dilatation. It showed the end of intrahepatic bile duct shaped like a bag in 41 cases, a enlarged gallbladder in 38 cases, and 9 cases with a soft intralumenal masses. There were 13 patients with pancreas swelling and 8 with pancreatic duct dilatation. Of the 20 patients underwent ERCP, eighteen cases showed intrahepatic bile duct diffuse dilatation with the end shaped like a bag, and 16 showed extrahepatic bile duct dilatation. Irregular filling-defect was seen in the common bile duct in 9 cases. The obstruction were relieved after Oddi's muscle endoscopic sphincrectomy(EST). Conclusion The patients with acute obstructive jaundice can be diagnosed as Clonorchiasis, if CT or ERCP showed equal intrahepatic bile duct diffuse dilatation with the end shaped like a bag and with extrahepatic bile duct dilatation, which can be confirmed by the worms and eggs found in the drawing-out bile, and the obstruction can be relived by EST.

Objective To investigate the CT imaging feature of EHCC associated with Clonorchiasis. Methods The CT image features of 18 patients with EHCC associated with Clonorchiasis proved by operation and pathology were reviewed retrospectively. Results CT depicited the level and cause of obstruction in all eigthteen patient. Most tumors( n =14,77.8%)were located in the proximal third of the extrahepatic bile duct. The gross morphologic pattern was an intraluminal soft tissue mass leision in 14 patients(77.8%), infiltrating in two patients and exophytic types in two patients. Contrast enhancement of the tumors relative to the liver parenchyma showed isoattenueation in 10 tumors(55.6%), hyperattenuation in seven tumors(38.9%) and hypoattenuation in one tumor(5.6%). Severe,uniform dilation of the intrahepatic bile duct was identified in 14 patients (77.8%) and central dilation was seen in four patients (23.2%).Male preponderance was found( n =15,83.3%). Conclusion It is concluded that the EHCC associated with Clonorchiasis is located predominantly in the proximal third of the extrahepatic bile duct and detected more readily than non Clonorchiasis-associated cholangiocacinoma.

Sleep plays an important role in the modulation of endocrine function and energy metabolism;hormone levels are markedly different during a sleepless night compared with a night of normal sleep.Sleep deprivation may change the levels of cortisol,growth hormone(GH)and thyrotropin(TSH)at night.In addition,sleep curtailment disturbs the balance of anorexi- genic(leptin)and orexigenic(ghrelin)factors,and does harmful to glucose tolerance.

Objective To discuss the cognition of the nursing disputes in undergraduates and the college nursing students in internship in Changchun and to provide some basis for them to improve the nursing quality in clinic.Methods The investigation was carried out to survey the cognition of the nursing disputes in 266 undergraduates and the college nursing students in internship in Changchun,and the results underwent analysis.Results Most undergraduates and college nursing students held the opinion that at present the relationship between patients and nurses was on a tight rope.94 people accounting for 72.3％ in undergraduate students,89 people accounting for 65.4％ in the college nursing students.Relevant factors which caused nursing disputes were related with the different education backgrounds.Conclusions We should make clear the causes of nursing disputes,and put forward the corresponding proposals according to nursing students with different education degrees.

Objectiye To study the mechanism by which transcranial magnetic stimulation (rTMS) affects cognitive dysfunction in vascular dementia (VD). Methods Thirty-six male Wistar rats were randomly divided into a control group, a VD group, a low frequency rTMS group and a high frequency rTMS group. Two-vessel occlusion was employed to induce VD models. Low frequency rTMS group rats were given 0.5 Hz rTMS for six weeks. High frequency rTMS group rats were given 5 Hz rTMS for six weeks. Morris' water maze test was used to measure their spatial learning ability and memory. The ultrastructures of the synapses in the four groups were detected with transmission electron microscopy. The expression of synaptophysin (SYN), brain derived neurotrophic factor (BDNF) and Nmethyl-D-aspartate receptor 1 ( NMDAR1 ) mRNA and protein in the hippocampus were determined by real-time PCR and Western blotting. Results The behavior and morphology of the rats treated with rTMS improved. The average expression of SYN, BDNF and NMDAR1 mRNA and protein in the low frequency rTMS group and the high frequency rTMS group were significantly higher than in the VD group. Conclusion rTMS can provide a rehabilitative effect for VD. The mechanism might be associated with enhancing the expression of SYN, BDNF and NMDAR1 in the hippocampus.

Objective To explore the characteristic and clinical meaning of myocardial bridge in patients with multi-slice spiral CT(MSCT) coronary angiography.Methods 875 patients with suspected or diagnosed coronary artery disease were studied with MSCT coronary angiography,579 cases were male and 296 cases were female,ranged from 30~87 years old in age with average of 60 years old.The heart was scanned with retrospectively ECG-gated,reconstruction from phase for all original tomographic source images at 30%~40% R-R phase interval according to heart rate ≥75 bpm and at 40%~50% R-R phase interval according to heart rate ≤75 bpm.The images of maximum intensity projection,multiplanar reconstruction and vulume reconstruction were gained to show left and right main coronary artery and their main branchs on mulliple angle.Results The myocardial bridges were detected in 89 cases,the positive rate was 10.2%,36 cases(40.5%)had different grade stenosis(≤50%).The myocardial bridges located at middle segment of anterior descending artery(79.8%),the thickness of myocardial bridge was 0.06~0.55 cm,the atherosclerosis plaques were found in 20 cases,the vascular stenosis was approximate to 50%.39 cases with simple myocardial bridges had angina,21 cases hadn’t angina.23 cases with myocardial bridges accompanied by coronary artery atherosclerosis had angina.Conclusion MSCT coronary angiography may clearly detect the myocardial bridge,which can provide more worthy information for clinical diagnosis and treatment.

Objective To study the effects and the mechanism of the ethanol extract of Blueberry(BE) on relaxation vascular endothelium or smooth muscle.Methods To use rat aorta as the specimen,to observe the effects of BE on induced relaxation of the phenylephrine-precontracted aorta.and approach the mechanism on vascular endothelium or smooth muscle.Results BE induced relaxation of the phenylephrine-precontracted(1.0×10~(-5)mol·L~(-1) aorta in a dose-dependent way(P<0.01),which was disappeared by removal of functional endothelium(P<0.01).Pretreatment of the aortic tissues with NG-nitro-L-arginine methyl ester(L-NAME),methylene blue,or 1H[1,2,4]-oxadiazole-[4,3_a]-quinoxalin-1-one (ODQ) inhibited the vascular relaxation induced by BE(P<0.01).BE-induced vascular relaxations were also markedly attenuated by addition of verapamil or diltiazem,while the relaxant effect of BE was not blocked by pretreatment with indomethacine,glibenclamide,tetraethylammonium(TEA),atropine,propranolol(P<0.01).Conclusion These results suggest that BE dilates vascular smooth muscle via endothelium-dependent nitricoxide-cGMP signaling pathway,possible involvement of L-type Ca~(2+) channel.

Objective Bone marrow mesenchymal stem cells ( BMSCs) , a kind of stem cells with multiple differentiation po-tentials, exist in the bone marrow and other organizations.This study aimed to investigate the repairing effect of the exogenous basic fi-broblast growth factor ( bFGF) against chronic obstructive pulmonary disease ( COPD) and its action mechanism, and to determine the expression of the bFGF gene in transfected rat BMSCs. Methods BMSCs were isolated, cultured and identified.The recombinant plasmid bFGF-pcDNA3.1 was constructed and sequenced.Liposome-mediated bFGF-pcDNA3.1 plasmid was transfected into the BM-SCs of the rat (bFGF-pcDNA3.1 transfection group), liposome-mediated pcDNA3.1 transfected into the BMSCs (pcDNA3.1 transfec-tion group) , and untransfected BMSCs used as the control.G418 screening was performed for 14 days.The gene and protein expres-sions of bFGF were determined by qRT-PCR and Western blot. Results The full-length sequence of the bFGF gene was consistent with that of the GenBank.The expression of the bFGF gene was significantly higher in the bFGF-pcDNA3.1 transfection group (7.028 ±0.568) than in the pcDNA3.1 transfection group (1.000 ±0.082) and the non-transfection control (1) (P<0.01), but with no statistically significant difference between the latter two groups (P>0.05).The expression of the bFGF protein was also re-markably higher in the bFGF-pcDNA3.1 transfection group (1.017 ±0.054) than in the pcDNA3.1 transfection group (0.217 ± 0.009) and the non-transfection control (0.165 ±0.013) (P<0.05), with no statistically significant difference between the latter two groups (P>0.05). Conclusion Mediated by the liposome reagent, the recombinant eukaryotic expression vector bFGF-pcD-NA3.1 can be transfected into rat BMSCs and expresses the bFGF gene and protein.
