At present, the roles of neural plasticity and motor functional recovery in stroke have increasingly been paid attention to. The remodeling of cerebral cortex after stroke can complement the function of injured tissues, which has been confirmed by animal experiments. Functional neuroimaging technique has been gradually used in the evaluation of neural plasticity.

Objective To investigate the effect of glycated albumin on recurrent cerebral infarction in elderly patients with diabetes mellitus. Methods All of 252 elderly acute cerebral infarction patients with diabetes mellitus were chosen from clinics. They were divided into 2 groups: A group ( glycated albumin <19.0% , 117 patients) and B group ( glycated albumin ≥ 19.0%, 135 patients). The clinical characteristics and the recurrent rate of cerebral infarction were compared between two groups. Results The levels of glycated albumin, fasting blood glucose, total cholesterol, low-density lipoprotein cholesterol and triglycerides in B group were significantly higher than those in A group:(21.00 ± 4.93)%vs. (16.75±1.72)%, (9.84 ± 2.89) mmol/L vs. (5.36 ± 1.00) mmol/L, (5.44 ± 1.30) mmol/L vs. (4.57 ± 1.00) mmol/L, (3.13±0.81) mmol/L vs. (2.58 ± 0.74) mmol/L, (2.34 ± 1.61) mmol/L vs. (1.74 ± 1.47) mmol/L, P<0.01 or<0.05. The recurrent rate of cerebral infarction in B group was significantly higher than that in A group: 53.3%(72/135) vs.36.7%(43/117), χ2 = 6.946, P = 0.008. Logistic regression analysis showed that the increase of glycated albumin was the independent risk factor of recurrent cerebral infarction in elderly patients with diabetes mellitus (P=0.048). Conclusions The recurrent rate of cerebral infarction is increased in elderly diabetes patients with high glycated albumin. The increase of glycated albumin is the independent risk factor of recurrent cerebral infarction.

Objective To evaluate the efficacy and clinical value of percutaneous transluminal angioplasty(PTA)with stenting for the treatment of superior vana cava syndrome(SVCS)with malignant causes.Methods A total of 13 patients with SVCS with malignant causes were enrolled in this study.Among the patients,2 had mediastinal cancer,and 11 had metastatic mediastinal tumor.The malignancy of the primary tumors of the 11 patients,including pulmonary cancer in 8,esophageal cancer in 2,and breast cancer in 1,were all confirmed by pathological examination.Via the right femoral vein,a pigtail catheter was introduced percutaneously into the proximate or remote end of the stenotic segment for the visualization of the SVC.After the location,length,and gravity of the stenosis were determined,Wallstent(Boston Scientific,USA)was placed into the SCV,if the patients had no local thrombosis in the stenotic segment.In one patient,a Z-shape stent(COOK,USA)was inserted simultaneously.For the cases complicated with thrombosis,the Wallstent was inserted after local thrombolysis.Results The procedure was completed in all the 13 patients with a success rate of 100%.The average length of the stenotic segment was 4.3 cm(3-6 cm).In one patient,two stents were used,while in the others only one stent was inserted.Thrombolysis was carried out before stenting in 6 patients.The intravenous pressure at the proximate end of the stenotic segment was determined with the patients supine before and after stenting.The pressure decreased from(26.2?1.6)cm H2O to(4.3?0.8)cm H2O after the operation.Postoperative angiography showed no collateral vein in the patients.The SCVS disappeared 0 to 3 days after the surgery.The patients were followed up for 8-26 months with a median of 13.During this period,8 patients died of multiple organ failure caused by multiple metastasis of the primary tumor in 4 to 10 months;the other 5 patients survived(3 of them received further therapies)without recurrence of SCVS.Conclusion PTA with stenting combined with local thrombosis is an effective and invasive treatment for patients with SCVS with malignant causes.

Objective To evaluate the effectiveness and method of intraarterial embolization in treatment of hepatic cavernous hemangioma. Methods 17 patients,8males and 9 females, were treated by super selective hepatic artery embolization with iodized oil, gelfoam pieces, and embolization coils. Results All patients had been embolized successfully. The rate of success was 100%. 11 cases were followed up by CT/USG for 1～12 months. The size of tumor was decreased more than 50% in 8 cases, more than 30% in 2 cases, and the effect was uncertain in 1 case. Symptoms of 11 patients were disappeared and relief was obvious in 5 cases.Total effective rate was 94% with no significant complications. Conclusions HAE is a safe and effective method. It may be considered as the first method of choice in treatment of hepatic cavernous hemangioma.

Objective To evaluate the effect of simpler and chemotherapeutic renal artery embolizations in the treatment of renal carcinoma preoperatively Methods 19 patients including simpler renal artery embolizaiton group( n =8) and chemotherapeutic renal artery embolization group( n =11) were retrospectively studied. The surgical procedures were recorded and pathology sections were observed for all the patients. Results All the preoperative embolization were achieved successfully. We found vessels obliteration of the renal carcinoma in the operation. In pathology, the tumor had clear border with the necrosis. Conclusions Preoperative renal artery embolization could decrease the risk in operation, and had positive effects on the prognosis of these patients.

Objective To study the etiology,pathogenesis,diagnosis and treatment of non-traumatic splenic rupture.Method The clinical data of patients with atraumatic splenic rupture from our hospital were retrospectively analyzed,and the liferatures were reviewed.Results Most cases were male.The average age was high.The etiological factors were diverse,and the most common being blood diseases,virus infection,local inflammation and neoplasm.The pathogenesis is related to splenomegaly,increase in splenic fragility,altered haemostatic mechanisms,malposition of the spleen,and violent contraction of the diaphragm.It is more difficult to arrive at a diagnosis when compared with traumatic splenic rupture.Most patients required splenectomy,especially when the etiological factors were malignant blood diseases or splenic tumors.Some patients received non-operative treatment.The prognosis was related to the etiological factors and age.Conclusions The etiological factors of non-traumatic splenic rupture were diverse,and pathological splenic rupture was most common.A preoperative diagnosis was difficult,and splenectomy was the most common treatment.

Objective To discuss the protective effect of carbon nanoparticles lymphatic tracer on parathyroid glands in the operation of thyroid carcinoma. Methods Retrospectively analyzed the clinical data of 65 thyroid carcinoma patients from January 2014 to October 2014, and they were divided into 2 groups according to whether injected with carbon nanoparticles. The experimental group (30 cases) were injected with carbon nanoparticles in thyroidglands before major procedure, while the control group (35 cases) were not injected. In the experimental group, there were 22 cases accepted total thyroidectomy of the affected side gland + isthmus thyroidectomy + subtotal thyroidectomy of the offside gland, and 8 cases of total thyroidectomy. In the control group, there were 25 cases accepted total thyroidectomy of the affected side gland + isthmus thyroidectomy + subtotal thyroidectomy of the offside gland,and 10 cases of total thyroidectomy. And all the 65 cases ac-cepted centrallymph nodes dissection. Results After carbon nanoparticles injection, central lymph nodes became black while parathyroid glands did not become black. The experimental group showed (2. 6 ± 0. 8) parathyroids each patient, and no parathyroid was cut by mis-take;the control group showed (1. 9 ± 0. 7) parathyroids each patient, and 3 parathyroids were cut by mistake. and the difference between the two groups was statistical meaningful (P<0. 05). There was no permanent hypoparathyroidism in the two groups. There was 1 cases of temporary hypoparathyroidism occured in the experimental group, and 3 cases occured in the control group, and there was no statistical sig-nificance difference between the two groups. Conclusion Carbon nanoparticles is benefit to the identification of parathyroid in surgery, and it can reduce the incidence of inadvertent parathyroidectomy, but it cann’ t reduce the incidence of hypoparathyroidism after procedure.
