The assessment of right heart function plays an important role in diagnoses, therapeutic decision-making, curative effects and prognoses of many congenital and acquired heart diseases. Recently, a lot of new techniques of echocardiography have been used to evaluate right heart function, such as DTI, MPI, 3-DE, AQ and CUS, which all have their own advantages and disadvantages.

Objective To investigate the effect of insulin combined with Edaravone therapy on delayed cerebral vasospasm (CVS) after experimental subarachnoid hemorrhage (SAH).Methods 40 New Zealand white rabbits were randomly separated into sham-operated group (n=8),SAH group (n=10),insulin group (n=10) and insulin+Edaravone group(n=12).SAH models were made by injecting blood twice into cisterna magna.30 min later of the first blood injected,the insulin 0.2 U/kg was subcutaneous injected in insulin group and insulin+Edaravone group,3 times daily for 7 d;while,the insulin+Edaravone group received Edaravone 0.5 mg/kg (intravenous injected in ear vein) twice a day for 7 d.7 d after the model made,the basilar artery cross sectional area was measured and the pathological changes were obseved to estimate the degree of CVS.The expression of insulin receptor(InRa) in vascular endothelial cell was detected by immunohistochemical staining.Results The basilar artery cross sectional area between insulin+Edaravone group[(0.46?0.3)mm2]and the sham-operated group[(0.48?0.4)mm2] was no significant difference;but they were obviously bigger than those in SAH group[(0.25?0.3) mm2] and the insulin group [(0.30?0.3)mm2](all P

Objective To observe the effect of rehabilitation education on upper-limb motor function in stroke patients. Methods 40stroke patients were divided randomly into treatment group and control group. The treatment group (n=20) accepted rehabilitation and rehabilitationeducation, and control group (n=20) accepted rehabilitation only. They were assessed with Modified Ashworth Scale (MAS),Fugl-Meyer Assessment (FMA) of upper-limb and Barthel Index (BI) before and after treatment. Results The scores of FMA and BI improvedin both groups after treatment (P<0.01), but the score of MAS improved only in the treatment group (P<0.01). The scores of FMA,BI and MAS improved more in the treatment group than in the control group (P<0.01). Conclusion Rehabilitation education plays an importantrole in motor function rehabilitation after stroke.

Objective To observe the effects of different models of rehabilitation education on stroke rehabilitation. Methods There were 35 stroke patients in group Ⅰ，40 patients in group Ⅱ. All the patients received the same rehabilitation treatment, but different model of rehabilitation education. They were evaluated with Functional Independence Measure (FIM) before and after treatment, and the incidence of complications were investigated. Results The FIM grade in all patients increased significantly after treatment (P<0.05), and increased more in the group Ⅱ (P<0.05). The incidence of shoulder pain/ shoulder subluxation, edema in hemiplegic extremity, muscle atrophy were a lower in the group Ⅱ than that in the groupⅠ (P<0.05). Conclusion Improving the model of rehabilitation education can improve the efficacy of stroke rehabilitation.

Objective To summarize experiences of microsurgical treatment of dumbbell tumors of the high cervical spine. Methods A series of 12 patients with dumbbell tumors of the high cervical spine were treated by using microsurgical techniques through posterior approach or antero-lateral approach. Results Complete resection was achieved in 10 patients. Postoperative neurological symptoms improved greatly in all. Conclusion The key points of treatment in dumbbell tumors of the high cervical spine are to analyze the preoperative image carefully and have knowledge about anatomy of high cervical spine as well as the experience of microsurgical technique.

Objective To investigate the prognostic value of AKT3 expression in gastric cancer. Methods AKT3 expression data in The Cancer Genome Atlas(TCGA)datasets and its clinical information were downloaded. Statistically assessed was performed for relationship with clinicopatho?logical factors and prognosis. Gene set enrichment analysis(GSEA)was used to predict the gene sets modulated by AKT3. Results The expres?sion of AKT3 was associated with T stage(P=0.001),TNM stage(P=0.049)and differentiation(P<0.001).High level of AKT3 expression indi?cates poor prognosis(P=0.001). AKT3 could regulate gene sets involving cell adhesion molecule,cytoskeleton regulation,focal adhesion and TGF?βsignaling pathway. Conclusion AKT3 could be used as a potential prognostic marker and a therapeutic target in gastric cancer.

Objective To investigate the factors of families related to the outcome of rehabilitation for cerebral palsy children. Methods Families of 153 cerebral palsy children were investigated with questionnaires of family condition, knowledge of cerebral palsy, compliance,and the Eysenck Personality Questionnaire, Marital Quality Questionnaire, Social Support Scale, Symptom Check List, Happiness Index.The children were assessed with Comprehensive Assessment for Disable Children before and after rehabilitation. Results There were significant differences of compliance, knowledge of cerebral palsy, being of other healthy children, personality of extraversion/introversion and lying,and mental symptom between the families of the cerebral palsy children improved or not after rehabilitation (P<0.05). Multivariate Logistic regression analysis showed that, being of other healthy children, personality of extraversion/introversion and mental symptom were the independent factors. Conclusion It may relate to the outcome of rehabilitation for cerebral palsy children of family condition, personality and mental health of the families, which need further intervention.

Objective To investigate a new strategy of bone marrow transplantation (BMT) for donor-specific tolerance induction after heart transplantation. Methods Donor bone marrow cells (BMCs)were harvested simultaneously with donor cardiac graft using modified perfusion method (PM) ,then stored in a -80 ℃ refrigerator after filtration and centrifugation. Whole BMCs (IBM-BMT) (monocytes 1.2 ×107/kg,CD34+ cells 2.38× 105/kg) in host iliac bones were injected into the bone marrow cavity 40 days after heart transplantation. Preconditoning regimens that consisted of fludarabine, antithymoctye globin and total lymphoid irradiation were performed 3 days before BMT. Tacrolimus (Tac) was administrated intravenously after BMT or orally in conjunction with mycophenolate mofetil (MMF) 3 weeks later.Cyclosporine and MMF were orally administrated 6 weeks later. Donor chimerism was detected using short tandem repeats-polymerase chain reaction in monocytes from peripheral blood at the 2nd,4th, 8th or 12th week after BMT or BMCs at the 4th, 8th or 12th week after BMT. Intramyocardium electrocardiography examination or endomyocardial biopsy was performed weekly or monthly respectively. Mixed lymphocyte reactions (MLR) were performed 3 months after BMT. Results Donor chimerism in monocytes in peripheral blood or BMCs in iliac bones measured at the 1 st,2nd and 3rd month after BMT was 26.3%, 19.1%,4.8% ,and 46.3%, 24.4%, 7.6%, respectively. After 3-month follow-up, there was no rejection confirmed by endomyocardial biopsy or intramyocardium electrocardiography. Echocardiography revealed that the diastolic and systolic function of the cardiac graft was maintained well 3 months after BMT. MLR revealed donor-specific hyporesponsiveness while immunocompetence was preserved to third-party antigens. Conclusion These findings indicate that the two-stage BMT strategy is a safe and feasible method for the induction of donor-specific tolerance via stable mixed chimerism and needs to be further confirmed after a long-term observation.
