Forty-seven patients with congenital heart disease and pulmonary hypertension were treated surgically. Among them, 31 were male and 16 female. The age ranged from 2 to 47(13. 7? 11. 2) years. Gongenital heart abnormalities included ventricular septal defect (VSD) in 20, huge atrial septal defect (ASD) in 1, VSD+ASI) in 12, VSD with patent ductus arteriosus (PDA) in 6, endocardial cushion in 2, VSD with aortopulmonary septal defect (APSD) in 1, double outlet right ventricle with PDA in 1 and total anomalous pulmonary venous connection in 1. Right heart catheterization was performed in 15 cases. The mean pulmonary artery pressure was (73 ? 24)mmHg, total pulmonary resistance was (78. 0 ?61. 2)kPa/(L/s). There were 7 cases examined in operation. Their mean pulmonary artery pressure was (55?13)mmHg. The others were examined by echocardiography. The mean pulmonary artery pressure was (49?15)mmHg. All patients were treated pre-op-eratively with oxygen inhalation therapy, hyperbaric oxygenation, prostaglandin E1 , respectively according to the degree of pulmonary hypertension. During cardiopulmonary bypass, pulmonary artery perfusion was performed with protective solution containing aprotinin for lung protection. Vasoactive drugs were routinely administrated postoperatively. There were 2 operative deaths with hospital mortality rate of 4. 3%. The cause of deaths was severe low cardiac output syndrome. The postoperative morbidity rate was 4. 3%. Our conclusion is proper peri-operative management could reduce post-operative mortality and morbidity for congenital heart disease with pulmonary hypertension.

Objective To investigate the clinical significance of small incision thoracotomy cardiac surgery in the management of heart diseases.Methods A retrospective analysis was made on clinical data of 115 cases of heart diseases treated with small incision thoracotomy surgery from September 2001 to October 2004 in this hospital.Results There were 108 cases of operation through a right small thoracic incision, 5 cases of robot-assisted operations,and 2 cases of occlusion of atrial septal defect(ASD) through a right small thoracic incision.The extracorporeal circulation time was 21~155 min(mean,145?26 min) and the aorta occlusion time was 8~108 min(mean,28?19 min).No operation-related death was seen.Postoperatively,a re-operation of open surgery was required for stopping bleeding in 1 case(0.9%,1/115),pulmonary atelectasis occurred in 3 cases(2.6%,3/115),and cerebral infarction happened in 2 cases(1.7%,2/115).Follow-up checkups in 82 cases for 6~24 months(mean,18 months) revealed no thoracic deformity.Conclusions With advantages of minimal injury,less bleeding,and quick closure of thoracic incision,right small incision thoracotomy is a good approach for the correction of cardiac deformities.

Aim To investigate the role of autophagy and its mechanism in Raji cell death induced by arse-nic trioxide. Methods Transmission electron micros-copy ( SEM) and MDC fluorescence staining were used to observe autophagy. MTT colorimetry was employed to assay the cellular proliferating activity. Cell apopto-sis and cell cycle analysis were performed using FITC-Annexin-V/PI double staining and flow cytometry ( FCM) . The expressions of LC3 and the conversion of LC3-I to LC3-II were measured by western bloting. The expression of bcl-2 mRNA and p53 mRNA were detected by reverse transcription-polymerase chain re-action ( RT-PCR ) . Results Arsenic trioxide could obviously inhibit the proliferation of Raji cells, arrest the cells at G2/M phase and induce apoptosis. Mean-while, arsenic trioxide markedly inhibited the expres-sion of bcl-2 mRNA and enhanced the expression of p53 mRNA in Raji cells. Arsenic trioxide also induced autophagy synchronously which paralleled with the in-duction of apoptosis in Raji cells, and 3-MA, an auto-phagy inhibitor, was able to reverse the arsenic triox-ide-activated autophagic activity, up-regulate bcl-2, down-regulated p53 expression and suppress the lethal effect of arsenic trioxide on Raji cells to reduce their sensitivity to arsenic trioxide. In contrast, the Rapamy-cin, an autophagy inducer, possessed the completely opposite effects on Raji cells compared with 3-MA. Conclusions The apoptosis and autophagic cell death are coexistent in arsenic trioxide-triggered death of Raji lymphoma cells, and Bcl-2 and p53 may play a key regulating role in this process.

Objective To assess the clinical value of dobutamine 201Tl stress-redistribution/nitroglycerin augmented ~(99m)Tc-metho~(99m)Tc-xyisobutylisonitrile (MIBI) gated myocardial perfusion imaging (MPI) in patients with coronary artery disease (CAD). Methods A total of 132 patients with suspected CAD underwent dobutamine 201Tl stress-redistribution/nitroglycerin augmented MIBI gated MPI and coronary arteriography (CAG) within two weeks after MPI. Percutaneous coronary interventions (PCI) were performed in 23 patients with myocardial infraction. The regional wall movement was assessed with echocardiography before and within three months after PCI. Results Taking stenosis ≥50% as standard of CAD, the sensitivity, specificity and accuracy of dual-isotopic SPECT imaging in diagnosing CAD was 93.41%, 87.80% and 91.67%, respectively. The sensitivity, specificity and accuracy in diagnosing left anterior descending artery (LAD) stenosis was 93.85%, 91.04% and 92.42%, for left circumflex artery (LCX) was 86.79%, 89.87% and 88.64%, while for right coronary artery (RCA) was 81.25%, 82.14% and 81.82%, respectively. Of all 207 myocardium segments in 23 patients with myocardial infarction, radioactivity defect was found in 113 segments on the redistributed ~(201)Tl images, and radiofilling was found in 52 (52/113) segments on the nitroglycerin augmented ~(99m)Tc-MIBI images, whereas 61 segments had no radiofilling. Taking regional wall movement improvement as the criterion of viable myocardium, the sensitivity, specificity and accuracy of identifying viable myocardium with nitroglycerin augmented ~(99m)Tc-MIBI imaging was 87.23%, 83.33% and 84.96%. Conclusion Dobutamine ~(201)Tl stress-redistribution/nitroglycerin augmented ~(99m)Tc-MIBI gated MPI is able to effectively detect CAD and viable myocardium and helpful in diagnosis and treatment of CAD.

Objective To analyze the image characteristics of chest schwannoma in coincidence 18FFDG SPECT studies,and to evaluate its prospective diagnostic function on chest schwannoma.Methods Four cases confirmed as schwannoma by surgery and pathology were enrolled in this retrospective study.Enhanced CT and coincidence 18F-FDG SPECT studies were performed before surgery.Imaging characteristics for the diagnosis of chest schwannoma were summarized.Results Tumors were totally removed by surgery.The histological diagnosis of schwannoma was confirmed by pathological,HE and immunohistological staining examination (positivity for the S-100 protein and vimentin),including 1 case of malignant schwannoma and 3 cases of benign.Four cases all showed high uptake of 18F-FDG.The uptake in malignant schwannoma was much higher than that in benign schwannoma.Benign schwannomas were noninvasive masses and mainly showed compression symptoms,with obvious lobulation and distinct borders.Malignant schwannoma was invasive masses.Conclusions 18 F-FDG coincidence SPECT is of limited value as a prospective diagnostic imaging technique for the identification of benign schwannoma from malignant schwannoma.But it could play an important role in the staging,restaging,and post-therapy follow-up of schwannoma.

Objective To value the clinical application of diffusion tensor imaging (DTI) in cerebral diseases. Methods Six volunteers and 6 patients (including 3 patients with ischemic stroke and 3 patients with glioma) were examined by DTI and T1weighted, T2weighted MR scan. All data were processed with DtiStudio software to show the white matter fiber tracts. The fractional anisotropy (FA) of the diffusion tensor were measured between the affected and the unaffected side. Results The white matter fiber tract could be observed clearly on the FA map. The pyramidal tract with different degree disruption could be showed in 3 patients with ischemic stroke. Compression, displacement, infiltration or destruction of pyramidal tract, corpus callosum or internal capsule and external capsule could be seen in 3 patients with glioma, and FA was significantly reduced on the affected side as compared to the unaffected side. Conclusion Diffusion tensor imaging is useful in observing the damage and displacement of the white matter fiber tracts in vivo, beneficial to the surgical plan for patients and prognosing recovery of function.

Objective To evaluate the diagnostic value of dobutamine?stressed cardiac morphing ( CM) MPI ( CMMPI) for coronary artery disease ( CAD) in middle?aged patients. Methods A total of 97 middle?aged patients (52 males, 45 females, age 40-65 (52.98±7.74) years) from March 2011 to Febru?ary 2015 with chest distress, cardiopalmus and chest pain symptoms ( suspected CAD) were retrospectively studied. Informed consents were signed by patients before examination. All patients underwent one?day dobu?tamine?stressed/rest CMMPI and CAG within one month. The diagnostic value of CMMPI was assessed and compared with CAG. Results CMMPI revealed 42 abnormal cases and 9 normal cases in 51 cases with cor?onary artery stenosis by CAG. CMMPI found 11 abnormal cases and 35 normal cases in 46 cases with normal coronary artery by CAG. In comparison with CAG, the sensitivity, specificity, accuracy, positive predictive value and negative predictive value of CMMPI were 82.35%(42/51), 76.09%(35/46), 79.38%(77/97), 79.25%(42/53)and 79.55%(35/44) respectively. The side effect was slight and transient with an inci?dence of 82.47%(80/97). Conclusion The dobutamine?stressed CMMPI has an important value for the diagnosis of CAD and the assessment of myocardial damage in middle?aged patients.

Objective To summarize the nursing care measures about patients with Epstein-Barr virus related post-transplantation lymphoproliferative disorder (EBV-PTLD) after allogeneic hematopoietic stem cell transplantation. Methods The nursing care measures about five patients with EBV-PTLD after allogeneic hematopoietic stem cell transplantation from October 2014 to May 2015 were summarized and analyzed. Results After carefully treating and nursing care, three patients were discharged. One patient with exacerbations, respiratory, epilepsy, liver failure, and disseminated intravascular coagulation was automatically discharged and then died. And the other patient died of other diseases. Conclusions Epstein-Barr virus infection is a complication after allogeneic hematopoietic stem cell transplantation. The key points to prevention and treatment of EBV infection included monitoring regularly, diagnosing and early intervention, which was proved to be effective, timely and active.
