Objective To study the possible cause and the feasibility of diagnosis and treatment of coronary disease after heart transplantation.Methods An 8-year survivor of heart transplantation received close follow-up. The clinical symptoms were recorded. Blood laboratory tests, electrocardiogram, endomyocardial biopsy, left ventricular Tc scintigraphy, endothelium-dependent vasodilatation of the brachial artery and coronary angiography were performed.Results The patient had good life quality without any symptoms such as chest discomfort, palpitation, dyspnea. Serum lipid and lipoprotein levels remained normal range. No any myocardial ischemic signs were detected in electrocardiogram. Endothelium-dependent vasodilatation was normal. No any acute rejective manifestation was observed in endomyocardial biopsy samples. Left ventricular Tc scintigraphy showed that left ventricular wall perfusion was progressively decreased. Coronary angiography showed that a typical vasculopathy with diffuse stenosis involved all coronary braches to some extent and right coronary had a proximal local severe stenosis with distal mild diffuse stenosis. Coronary angioplasty and stent placement of proximal right coronary was performed. The perfusion of the left ventricular wall was improved by this angioplasty.Conclusion Chronic rejection is probably the main cause of coronary disease after heart transplantation. Serial left ventricular scintigraphy can detect the change of myocardial perfusion. Local severe stenosis of coronary after heart transplantation can be treated by coronary stenting.

Objective To investigate living quality of patients after orthotopic cardiac transplantation and to provide scientific evidence for specific strategy of therapy and improvement of living quality of patients with cardiac transplantation. Methods SF-36 and the social support questionnaire were used to analyze living quality of 79 patients who received orthotopic cardiac transplantation in the Department of Cardiovascular surgery of Affiliated Union Hospital of Fujian Medical University. The mode of SF-36 was from the investigative numerical value of residents in Sichuan province. Description, t-test and Spearman correlation analysis were used to study the related factors. Results Compared with a reference general population, the heart transplant recipients showed a significantly worse living quality score on all domains of the SF-36 scales (P<0. 05), except the domain of somatic pain. Among the patients after cardiac transplantation, living quality was more significantly improved in >2-year survival group than that in <one-year survival group (P<0. 05),except the domain of somatic pain. The relationships between the social support and living quality were analyzed,and it was found that as compared with a reference general population, the heart transplant recipients showed significantly lower scores on all domains of the social support questionnaire (P<0. 01 ). The total social support scores were positively related to mental health related living quality (P<0.05, r = 0.223 - 0.710), except the domain of somatic pain. Conclusion Compared with a general population, heart transplant recipients demonstrated a significantly worsened living quality. But evidence showed the living quality can be improved gradually with the prolongation of the survival time after heart transplantation. Social support was related to the living quality of heart transplantation patients. Improvement of availability on social support will probably improve living quality.

AIM: The aim of this study was to investigate the hemodynamic characteristics of the denervated orthotopic transplanted hearts. METHODS: Eighteen patients with end - stage cardiopathy underwent orthotopic cardiac transplantation received immunosuppressive induction therapy. The changes of hemodynamics were closely monitored during the perioperative period and the periodic check-up of echocardiogram and electrocardiograph were followed up in the postoperative long-term period. RESULTS: All recipients were received vasoactive drug and active diuretic therapy during the perioperative period. An increase in central venous pressure in concomitance with decrease in cardiac output, cardiac index and mixed venous oxygen saturation within 24 to 48 hours and tend to stable 48 hours postoperation were detected. In the follow - up period, the cardiac functions of allografts were all recovered well. No recipient complained angina pectoris. CONCLUSIONS: The hemodynamic characteristics and clinical pharmacological therapeutic implications of cardiac denervation are very unique. Rational application of inotropic support and diuretic therapy and vasodilatation combined with prudent administration of some agents, which affect the physiology of denervated heart, are the most effective measures for the prevention of postoperative complications of cardiac allograft.

Objective To establish the SD rat aortic dissection(AD)model by using both BAPN and AngⅡ,in order to investigate AD's pathogenesis. Methods 90 three weeks old SD rats were equally divided into three groups randomly:control group,medicine gavage group and blank medicine gavage group. Rats in control group were fed on a regular diet;BAPN ( 1g/ kg per day)was forced into rats'stomach in the medicine gavage group;the same volume saline was forced into rats' stomach in the blank medicine gavage group. 4 weeks later,when the rats were 7 weeks old,we stopped giving them BAPN, but to implant an omicro-osmotic pump subcutaneously in the abdomen. The pumps in control group and blank medicine gavage group were filled with 0. 9% saline,the medicine gavage group'pumps were filled with AngⅡsolution( 1 μg·kg- 1 ·min- 1 ). 1 week later,all the survivals were dissected after anesthesia and the aortic vessels were acquired. All the acquired aortic ves-sels were proceed pathological examination. All the rats dead during the process of the experiment were dissected immediately to get the aortic vessels and proceed pathological examination. Results All rats in control group and blank medicine gavage group were survival,there was no aortic dissection or death. In medicine gavage group, 15 rats developped aortic dissection, 12 a-mong them were died of aortic dissection rupture,the aortic dissection formation rate was 50% . Conclusion Using BAPN and AngⅡ to establish the SD rat AD model is feasible,it is simple and practicable,meanwhile,it has high aortic dissection for-mation rate. The process is similar with human's aortic dissection process.

BACKGROUND:The authors found that when the bilateral percutaneous vertebral augmentation is used to treat osteoporotic vertebral compression fractures with a total bone cement injection of 4 mL or more,different distribution patterns were usually presented on the X-rays;however,there were few reports addressing the effects of these patterns of bone cement distribution on the biomechanical properties of fractural vertebrae. OBJECTIVE:To further explore the biomechanical effects of different bone cement filling doses and distribution patterns on biomechanics of the fractural vertebrae using the finite element method. METHODS:The L1-L3 finite element models of osteoporosis were established,and the vertebral compression fractures were simulated in L2.Four distribution patterns bilateral partial fusion(FH type),full fusion(FO type),symmetrical separation(SA type),and asymmetric segregation(SN type)were simulated in 4 and 6 mL injections in the osteoporotic vertebral compression fracture models,respectively,and a total of nine sets of models were obtained.These models were solved under the same boundary conditions and compared with the stress and displacement of the L2 fractural vertebra. RESULTS AND CONCLUSION:(1)The maximum stresses of the nine groups of models were concentrated in the L2 fractural area,and the maximum stress and maximum displacement of each filling model were lower than in the osteoporotic vertebral compression fracture model,indicating the effectiveness of bone cement filling in the treatment of osteoporotic vertebral compression fracture.(2)Compared with 4 mL bone cement filling,6 mL bone cement filling could significantly reduce the stress of fractured vertebrae and enhance the strength of fractured vertebrae while improving the stability of fractured vertebrae.(3)In the same state of movement,the FH type stress was the least,followed by the SA type,both of which were close.FO type stress was the largest,especially in the lateral bend,which might be associated with its cluster shape resulting in the concentration of lateral stress.In the aspect of displacement,FH type was the least and FO type was the largest.(4)The results show that increased dose of bone cement injection reduces fractural vertebral stress and improves stability,but increases the risk of leakage.Bilateral symmetrical dispersed bone cement(FH type,SA type)is superior in restoring vertebral strength and stability than full fusion(FO type),asymmetric separated(SN type)bone cement.Therefore,when clinically performing bilateral percutaneous vertebral augmentation treatment of osteoporotic vertebral compression fractures,the bilateral symmetric dispersions of the distribution are first guaranteed;priority is recommended for FH type distribution,for appropriate stress stimulation and best stability.
