Objective To evaluate the value of echocardiography in patients with isolated anomalous origin of right pulmonary artery from ascending aorta. Methods The eehoeardiographie results of five patients with isolated anomalous origin of right pulmonary artery from ascending aorta were reviewed retrospectively. Results Severe pulmonary hypertension occurred in all the patients,besides accompanied with patent duetus arterious, no other congenital malformations combined. Three patients underwent operation. Patent ductus arterious was missed in one patient's diagnosis. Another patient was missed isolated anomalous origin of right pulmonary artery from ascending aorta in several echoeardiographic examinations, once misdiagnosed as complete transposition of the great arteries. Conclusions There are many anatomic and hemodynamic similarities in patients with isolated anomalous origin of right pulmonary artery from ascending aorta. Grasping their common charaeters and exploring multi-position and multi-section are helpful to make correct diagnosis.

Objective To explore effects and mechanism of inactivation of vitamin D receptor (VDR) in intestinal tumor growth of APCmin/+ mice. Methods To generate APCmin/+VDR -/- mice through breeding, the number and size of small intestinal and colonic tumors were assessed and compared between APCmin/+ and APCmin/+ VDR -/- mice. The intestinal tumors were diagnosed with HE stain. The expressions of BCL-2,vimentin-1,Stat-1 and MSH-2 proteins of tumors were determined by immanohistocbemistry and compared be-tween APCmin/+ and APCmin/+VDR -/- mice. Results A comparison between APCmin/+ and APCmin/+ VDR -/- mice revealed that the number of the tumors, which were larger than 3mm, was significantly increased in APCmin/+ VDR -/- mice at 4 months of age (P< 0.01). HE staining indicated fistulous adenomas from small intestine and colon of two groups, Immunostaining showed Stat - 1 level in APC-min/+ tumors were increased and MSH-2 and vimentin-1 levels in APCmin/+ VDR-/- mice were increased, compared to APCmin/+tumors. Conclusion These observations suggested that inactivation of VDR promoted the intestinal tumor growth of APCmin/+ mice.

Objective To evaluate the usefulness of real-time three-dimensional transesophageal echocardiography(RT-3D-TEE)in cardiac valvular diseases.Methods Preoperative and postoperative RT-3D-TEE studies were performed in 32 patients who had undertaken cardiac valve repair or valvular replacement using Philips iE33 with X7-2 probe,and quantitative analysed the mitral structure in cases of mitral valve prolapse by using online QLAB7.0 quantitative analysis software.Results RT-3D-TEE can demonstrate the anatomicsl structure clearly,evaluate the function of cardiac valves precisely,and reveal details of type,position and extent of lesions vividly in surgical view.RT-3D-TEE helped correct misdiagnose in 2 cases,revised surgical plans in 3 cases,and guided implementation of remedial surgery in 1 case.Conclusions RT-3D-TEE can present images lively,and it can provide adequate information for preoperative diagnosis,aid the formulation of surgical plan and evaluate surgical effect.

Objective To research the feasibility and accuracy on echocardiography measurement aortic annulus diameter(AAD)at the plane of three Junctions of aortic valve leaflets by real-time three-dimensional transesophageal echocardiography(RT-3D-TEE).Methods Twenty-three patients underwent echocardiography and aortic valve replacement because of acquired aortic valve disease.The AAD was measured in parasternal left ventricle long axis view(TTE-AAD)by transthoracic echocardiography(TTE)preoperative.The AAD was measured in left ventricle long axis view(TEE-AAD)and the distance of three iunctions of aortic valve leaflets (N,L,R) was measured in aortic short axis view by RT-3D-TEE intraoperative.The three-dimensional full volume images were analyzed by online QLAB 7.0 software.The AAD was measured by standard cylindrical valve sizer (OP-AAD)before aortic valve replacement surgery,too.Results Comparing with the three aortic valve leaflets of acquired aortic valve disease,the lines between their junctions constituted an approximate equilateral triangle regardless of the cause and degree of disease,and the length of the three groups was no significant difference(P>0.05).There was no significant difference between TTE-AAD and OP-AAD group(P>0.05),and the correlation was good(r=0.84).The N,L and R group compared separately with the OP-AAD group, there was no significant difference(P>0.05)and correlation was superior to TTE-AAD group(r=0.94, 0.97, 0.96).The difference between TEE-AAD and OP-AAD were significant(P<0.01).Conclusions Echocardiography measurement of AAD at the plane of three junctions of aortic valve leaflets is feasible,and it is better accuracy and repeatability comparing with parasternal left ventricle long axis view.

Objective To investigate epidemiological and clinical features of patients with clonorchiasis sinensis infection. Methods The epidemiological, clinical, laboratory and treatment data of clonorchiasis patients in Department of Infectious Diseases, Second Affiliated Hospital, Harbin Medical University from 2002 to 2004 were retrospectively analyzed. Results Sixty-eight point two percent patients had a history of eating raw freshwater fish and shrimp. Patients with occupations as cook, fish stock man, fishing man and fishmonger accounted for 22.6%. The transmission route was not clear in 9.1% of patients. The common clinical manifestations were abdominal pain (60.3%), fatigue (52.3%), diarrhea (33.0%), anorexia (69.3%), jaundice (23.9%), hepatomegaly (59.1%), splenomegaly (8.0%), dizziness (20.9%), fever (5.7%) and biliary colic (14.8%). Twenty-eight point four percent were asymptomatic. Other findings included liver dysfunction (70.4 %) and eosinophile granulocyteosis(69.3 %). Negative rate of stool egg of clonorchis sinensis after treatment with praziquantel or albendazole was 91.9% or 86.5%, respectively. There was no significant difference between the two groups ( χ2 = 0.561, P = 0.454). Conclusions Clinical manifestations of patients with clonorchiasis sinensis are complicated and often accompanied with liver dysfunction. Clonorchiasis sinensis is often misdiagnosed and should be paid much attention.

Glutathione S-transferase (28GST) with molecular mass of 28 kDa is an antioxidant enzyme abundant in Clonorchis sinensis. In adult C. sinensis, 28GST was localized in tegumental syncytium, cytons, parenchyma, and sperm tails examined by immunoelectron microscopy. C. sinensis 28GST was earlier found to neutralize bioreactive compounds and to be rich in eggs. Accordingly, it is suggested that 28GST plays important roles in phase II defense system and physiological roles in worm fecundity of C. sinensis.

Purpose To establish myocardial infarction model in rabbits and to evaluate cardiac function and pathological changes.Materials and Methods In 35 New Zealand white rabbits, the left anterior descending branch (LAD) of the coronary artery was ligated. The cardiac function was evaluated using echocardiography, and the blood serum brain natriuretic peptide (BNP) level was examined preoperatively, on postoperative day 1, and in 1 week, 2 weeks, 4 weeks and 8 weeks for comparison. Pathological sections and HE staining were performed to observe pathological changes. Results The death rate was 28.6% (10/35). There was progressive increase in left ventricular end systolic diameter (LVESD) and left ventricular end diastolic diameter (LVEDD) at 1 week, 2 weeks and 4 weeks (P<0.05). There was progressive decrease in left ventricular ejection fraction (LVEF) and left ventricular fractional shortening fraction (LVFS) at 1 day, 1 week, 2 weeks and 4 weeks (P<0.05). The BNP level started increasing in 1 day, peaked in 1 week, then gradually decreased but remained higher than preoperative level in 8 weeks (P<0.01). Pathological section showed typical myocardial cell degeneration, necrosis, ifbrosis, calciifcation and scar formation. Conclusion This myocardial infarction model is satisfactory with signiifcant decrease of cardiac function and increase of BNP level.

OBJECTIVETo observe the clinical efficacy of Wangbi Tablet (WT) on the treatment of knee osteoarthritis (KOA), and to study its treatment program by integrative medicine.

METHODSThe randomized, parallel control, and multi-center clinical observation method was used. 160 KOA patients of Gan-Shen deficiency complicated with stasis-blood blockade syndrome were assigned to three groups. Group A (72 cases) was treated by WT, Group B (42 cases) was treated by Votalin Tablet, and Group C (46 cases) was treated by WT + Votalin Tablet. All patients were treated for two months. Before and after treatment the clinical symptoms, the knee function activity, adverse reactions were observed and recorded. Erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) of each patient were respectively detected, statistically analyzed and compared.

RESULTSAfter eight weeks of treatment significant difference was shown in the time of morning stiffness in joints, joint tendemess, swelling, pain, joint functional activities, ESR, and CRP between Group A and Group B (P<0.01). Besides, better effects were obtained in Group C (P<0.01). Improvement of ESR and CRP: They were obviously improved in the three groups after treatment (P<0.01). As for the markedly effective rate, better effects were obtained in Group C (P<0.05).

CONCLUSIONSIn the treatment of KOA, WT showed favorable effects with no obvious adverse reaction. The combination of WT and Voltaren Tablet was significantly superior to use of WT or Votalin Tablet alone. It could reduce the dosage of Voltaren Tablet and avoid adverse reactions of the gastrointestinal tract.
