Objective To study curative efficacy of benazepril combined with atorvastatin on N-terminal pro-brain natriuretic peptide (NT-proBNP) and its efficacy in the treatment of chronic cardiac failure. Methods 90 patients of chronic heart failure were selected as research objects. The control group were treated with benazepril, while the observation group were treated with benazepril combined with atorvastatin, 45 cases in each group. Then before and after treatment of 6 months, the cardiac function of left ventricular end-diastolic dimension (LVEDD), left ventricular end systolic dimension (LVESD), left ventricular eject fraction (LVEF), C-reactionprotein (CRP), interleukin- 6 (IL-6, tumor necrosis factor α (TNF-α) and plasma NT-proBNP levels were compared between two groups, and the efficacy was observed. Results After treatment, LVEDD and LVESD in observation group were lower than those in control group, the LVEF was higher than that in control group(P<0.05). The CRP,IL-6 and TNF-αlevels in observation group were lower than those in control group(P<0.05). The plasma NT-proBNP level in observation group was significantly lower than that in control group(P<0.05). The total effective rate of observation group was statistically higher than that that in the control group 95.55%(43/45)vs. 77.77%(35/45)(P<0.05). Conclusion Benazepril combined with atorvastatin in the treatment of chronic heart failure is significant, can reduce plasma NT-proBNP levels, improve the inflammatory factor.

Objective To discuss the diagnosis and inductive chemoradiotherapy of stage Ⅲ and stage Ⅳa invasive thymoma.Methods Clinical data of 13 cases with incomplete resected invasive thymoma were analyzed retrospectively,among which 8 cases were in stage Ⅲ and 5 cases in stage Ⅳa.All the 13 cases had invasion of major vessels,pericardial and lung tissues,or had metastasis of pleura and pericardium.Each patient got pathological diagnosis by fine needle aspiration,video-assisted thoracoscopic biopsy or anterior mediastinal biopsy.After 3 cycles of NP or CAP inductive chemotherapy and synchronous radiotherapy,tumors shrank and got palliative or complete surgical resection.The Follow up ranged from 2.8 to 9 years.Results All the 13 cases were malignant thymoma,including 4 cases of type B2,6 cases of type B3 and 5 cases of type C.7 patients got radical resection and 2 got palliative resection.9 patients survived more than 3 years after operation,7 patients survived more than 5 years,one patient even lived 8 years,and the other 4 patients without getting surgery died in 4 years.Conclusion Inductive chemoradiotherapy could shrink stage Ⅲ and stage Ⅳa invasive thymoma,reduce clinical stage,improve the resection rate,and prolong survival.

Methods AD tree shrew model was established by intracerebroventricular injection with amyloid-βpeptide (Aβ) . Since the eighth day after injection, the tree shrews were treated with gastrodin for thirty days. The expression of BDNF in tree threw hippocampus was detected by reverse transcription polymerase chain reaction (RT-PCR) . Results The expression of BDNF mRNA in the treatment group was higher than that in the model group ( <0.05) . Conclusion Gastrodin can increase some degree of the expression of BDNF.

Objective To investigate the influence of electroacupuncturing Neiguan points on mitochondrial Ca2+release and cardiomyocyte apoptosis of diabetic cardiomyopathy in rats. Methods 30 Wistar rats were randomly divided into a control group, a model group and a treatment group(10 in each group). In the treatment group, after eight weeks electroacupuncture Neiguan point treating diabetic cardiomyopathy in rats, the myocardium was quickly removed,mitochondrial was extracted,dual-beam UV spectrophotometer was adopted to detecting Ca2+transportation by testing Ca2+indicator A Ⅲ absorbance, and Cardiomyocyte apoptosis was evaluated by terminal-deoxynucleotidyl transferase mediated deoxy-UTP nick end labeling (TUNEL). Results Ca2+ indicator A Ⅲ absorbance detection(0.051±0.014) and cardiomyocyte apoptosis(0.49±0.36)were more depressed in the treatment group than in the model group[(0.077±0.025), (0.53±0.04)], there were significantly different(P<0.05) Conclusion Effect of Electroacupuncturing Neiguan points decreased myocardial apoptosis index in rats with diabetic cardiomyopathy, which may be related to the reduction of mitochondrial Ca2+influx.

Objective:To evaluate the effectiveness and safety of endovascular treatment in solving symptomatic cerebral artery tandem lesions.Methods:From June 201 2 to February 201 4,1 2 cases (24 lesions)with symptomatic cerebral artery tandem lesions were accepted for the endovascular treatment. The distributions of the tandem lesions were as follows:the common carotid artery and internal carotid ar-tery (1 case),the internal carotid artery and the proximal of the carotid cavernous sinus segment (3 ca-ses),the internal carotid artery and the distal of the carotid cavernous sinus segment (4 cases),the in-tracranial segment of internal carotid artery and middle cerebral artery M1 segment (2 cases),the first segment of vertebral artery and intracranial segment of vertebral artery (2 cases).All of these cases were treated from distal lesions to proximal lesions except for tandem lesions in the internal carotid artery and the distal of the carotid cavernous sinus segment in order to obtain better support.Tandem lesions were treated in the same operation with local anesthesia or general anesthesia.The procedures of the 1 2 cases retrospectively were analyzed and the peri-operation complications and responsibility region recurrent is-chemic stroke incidents observed.Results:All tandem lesions were solved successfully all at once.There were no peri-operation complications or recurrent ischemic stroke incidents.There were no recurrent is-chemic stroke incidents or stent restenosis cases in the follow-up.Conclusion:It is safe and effective for selective endovascular treatment in solving symptomatic cerebral artery tandem lesions at the same time, but we should take careful preoperative evaluation and improve the operation plan.

Objective:To study the morphology of middle cerebral artery ( MCA ) M1 segment .Me-thods:We selected the MRA data of 794 MCA (400 of the left side and 394 of the right side ) from Ja-nuary 1, 2011 to June 30, 2011 consecutively and analyzed the morphology of the MCA M 1 segment in axial, anteroposterior and lateral view , measured the length of the M1 segment, and analyzed the simila-rity of the left and right side M1 segment morphology .Results:In axial, anteroposterior and lateral view , the MCA M1 segment showed C-shape >L-shape >S-shape .In axial view , it was about 373 ( 47%) M1 segment performance for the C-shape, of which 340 (42.8%) M1 segments showed bowing to the dorsal side, only 33 (4.2%) M1 segments showed bowing to the ventral side .In anteroposterior view, it was about 322 (40.6%) M1 segments of the performance of the C-shape, of which 262(33.0%) M1 segments showed a bowing to the superior , 60 (7.6%) showed bowing to the inferior .The similarity of the left and right MCA M1 segments was 27.2% (114/419) in axial view and 42.7% (179/419) in anteroposterior view.It was more similar in anteroposterior view than in axial view .Along with the increase of age, in the axial view, L-shape converted to C-shape very obviously, but only mildly elevated in S-shape .In anteroposterior view , the L-shape converted to the C-shape or S-shape along with the increase of age.Conclusion:The different morphology of MCA M1 segment in axial and anteroposterior view may be involved in the development of intracranial atherosclerosis .
