ObjectiveTo observe the effect of combined rehabilitative training on stroke patients in convalescent stage.Methods52 stroke patients with hemiplegia were divided into rehabilitation group (n=26, receiving combined rehabilitative training) and control group (n=26, not receiving combined rehabilitative training). Scores of functional independence measure (FIM) and Fugl-Meyer assessment (FMA) of all patients were assessed when admission and discharge.ResultsFor patients of rehabilitation group, FMA scores when discharge was not significant difference compared with admission, but FIM scores was significantly higher than that of control group (P<0.01).ConclusionCombined rehabilitative training can improve function and living quality of stroke patients in convalescent stage.

Objective: To study the impact of astragaloside on ventricular remodeling and peroxisome proliferator activated receptor a (PPARa) expression in pressure-overload rats and to preliminarily explore its mechanism. Methods: Pressure-overload rat's model was established by abdominal aorta constriction (AAC) in 8-week old SD rats and the result was conifrmed by echocardiography at 6 weeks later. Pressure-overload rats were divided into 4 groups with different intragastric treatment: Model control (normal saline) group, Benazepril hydrochloride [10mg/(kg.d)] group, Low-dose astragaloside [40mg/(kg·d)] group and High-dose astragaloside [80mg/(kg.d)] group; in addition, Sham operation group, the rats received intragastricnormal normal saline.n=20 in each group and all animals were treated for 8 weeks. Rat's cardiac structure and function indexes were assessed by echocardiography, hemodynamic parameter was examined by left ventricular intubation, myocardium and blood levels of free fatty acid (FFA) were determined, morphological changes of myocardial tissue was observed by HE and Masson staining, mRNA and protein expressions of PPARa were measured by qRT-PCR and Western blot analysis. Results: Compared with Sham operation group, Model control group showed increased left ventricular mass index(LVMI), collagen volume fraction (CVF) and FFA level, allP<0.05, while decreased mRNA and protein expressions of PPARa, bothP<0.05. Compared with Model control group, Low-dose and High-dose astragaloside groups presented reduced LVMI, CVF and FFA level, allP<0.05-0.01, while elevated mRNA and protein expressions of PPARa, bothP<0.01. Conclusion:Astragaloside IV mayinhibit myocardial remodeling in pressure-overload rats, which might be via up-regulating mRNA and protein expressions of PPARa, enhance myocardiumFFA utilization, and therefore improve myocardial energy metabolism.

AIM: These studies aimed at exploring the alteration of intracellular Ca 2+ level in the course of macrophage-derived foam cell formation as well as its mechanism.METHODS: Foam-like cell was generated by peritoneal macrophage of C57BL/6J mouse, which is susceptible to atherosclerosis, incubated in 10 mg?L -1 oxidized low density lipoprotein for 96 hours. With the technique of Ca 2+ fluorescent indicator and the assay of NADH-oxidizing coupling spectrum-alteration, the intracellular Ca 2+ level and membranous Ca 2+ -ATPase activity of the above foam-like cell were determined.RESULTS: The foam-like macrophage Ca 2+ level was 2.7 times higher than the control macrophage, and the former Ca 2+ -ATPase activity was 24% of the later.CONCLUSION: The results suggested that macrophage-derived foam cell formation was connected with slow Ca 2+ entry or release, which possibly derived from long lasting opening of membranous Ca 2+ channels at the early stage and irreversible inactivating of membranous Ca 2+ pump at the late stage.

AIM:To observe the effects of astragaloside IV (AS-IV) on myocardial fibrosis in chronic heart failure ( CHF) rats and to explore the underlying mechanism preliminarily .METHODS:Chronic heart failure model rats established by abdominal aorta constriction (AAC) were divided into CHF group, valsartan group and AS-IV group.Sham operation group was also established .The rats in valsartan group and AS-IV group received valsartan and AS-IV at 2 and 30 mg· kg-1 · d-1 , respectively.The rats in sham operation group and CHF group received normal saline .After 8 weeks of treatment, the cardiac structure and the hemodynamic parameters were measured .The morphologic changes of myocardial tissue were observed after staining .The expression of long-chain acyl-CoA dehydrogenase ( LCAD) and 6-phosphofructoki-nase-1 (PFK1) at mRNA and protein levels was determined by RT-qPCR and Western blot.RESULTS:Compared with sham operation group , left ventricular mass index ( LVMI) , collagen volume fraction ( CVF) , left ventricular posterior wall depth (LVPWD), and the mRNA and protein of PFK1 in CHF group were increased (P<0.05), while the mRNA and protein levels of LCAD were decreased (P<0.05).Compared with CHF group, the LVMI, CVF, LVPWD, and the mRNA and protein levels of PFK1 in valsartan group and AS-IV group were decreased (P<0.05), while the mRNA and protein levels of LCAD were increased (P<0.05).CONCLUSION:AS-IV inhibits myocardial fibrosis in the CHF rats , the mechanism of which might be associated with up-regulating the expression of LCAD , down-regulating the expression of PFK1 and normalizing the myocardial energy metabolism .

Objective To observe the effect of therapy combined with rehabilitation approach and acupuncture on cerebral trauma during the recovery stage. Methods 48 cases were divided into two proups: 24 cases in treatment group who applied the rehabilitation combined with acupuncture, the other 24 cases in control group who applied acupuncture alone. They were evaluated with Functional Independent Measure (FIM) 3 months after treatment. Results The scores of FIM were significantly difference between these two groups (P<0.05). Conclusion The therapy combined with rehabilitation approach and acupuncture can improve the recovery of cerebral trauma.

Background and purpose: Factor that binds to the inducer of short transcripts of human immuno-deficiency virus-1 (FBI-1) in a variety of malignant tumors showed high expression levels, which may be closely related to tumor proliferation and differentiation, angiogenesis, metastasis, but its relationship with breast cancer has not been fully elucidated. The purpose of this study was to investigate the expression of FBI-1 in breast cancer cells, and to study the effect of FBI-1 gene expression on the proliferation of breast cancer cells and its possible mechanism. Methods:Real-time fluorescent quantitative polymerase chain reaction (RTFQ-PCR) and Western blot analysis were applied to detect FBI-1 expression in normal human mammary epithelial cell line MCF-10A and breast cancer cell MCF-7. RNA interference method was used to down-regulate FBI-1 expression in MCF-7 cells. The cell proliferation was measured by CCK-8 kit and colony formation assay. RTFQ-PCR and Western blot were used to detect the expression of FBI-1 and NF-κBp65 in MCF-7 cells before and after the interference of FBI-1 expression. Results: The expression of FBI-1 was higher in breast cancer cells than that in normal human mammary epithelial cells (P<0.05). The effects of FBI-1 down-regulation inhibited proliferation in MCF-7 cells (P<0.05). At the same time, after inhibition of FBI-1, the NF-κBp65 mRNA and protein expression levels were significantly decreased (P<0.05). Conclusion: FBI-1 is highly expressed in breast cancer cells. Down-regulated FBI-1 expression can inhibit the proliferation of breast cancer cells,and its mechanism may be related to the inhibition of NF-κB signaling pathway.

Objective To explore the diagnosis and surgical treatment of pulmonary sequestration in adults. Methods Clinical data of 21 cases of pulmonary sequestration whose diagnosis was confirmed by surgical biopsy in our department from March 2009 to February 2016 were retrospectively analyzed. Divided the patients into the thoracotomy group (n=9) and the thoracoscope group (n=12) according to dif-ferent surgical methods, and compared the diagnosis and surgery of the two groups. Results Among the patients, 8 cases were diagnosed as pulmonary sequestration and the remaining 13 cases were misdiagnosed,with the misdiagnosis rate of 61. 9%. Intraoperative exploration dem-onstrated that the abnormal blood vessels were originated from thoracic aorta (n=14,66. 7%),abdominal aorta (n=4,19%),phrenic artery (n=3,14. 3%) and aortic arch (n=1,4. 8%), and there were 20 cases (95. 2%) of intralobar sequestration and 1 case (4. 8%) of ex-tralobar sequestration. Patients underwent thoracotomy and patients underwent video-assisted thoracoscopic surgery were of no significant differences in operative time (P=0. 104),blood loss (P=0. 209),chest tube duration (P=0. 511),drainage volume (P=0. 135) and postoperative hospital stay (P=0. 450). All the patients recovered well after surgery. Conclusion As pulmonary sequestration lacks specific clinical manifestations,missed diagnosis and misdiagnosis are very common in patients. Chest enhanced CT and CT angiography are effective diagnostic methods at present. Both thoracotomy and VATS can achieve good therapeutic effects.

Objective To investigate the indication and result of parental artery occlusion, embolization with coils, stents in treatment of the traumatic carotid artery pseudoaneurysm. Methods There were six patients with traumatic carotid artery pseudoaneurysm including three patients of cavernous pseudoaneurysm combined with carotid-cavernous fistula (CCF), two with simple traumatic carotid artery pseudoaneurysm and one with traumatic carotid artery pseudoaneurysm that was found after CCF embolization with detachable balloon. The treatment included balloon occlusion for CCF and traumatic carotid pseudoaneurysm in one patient, coil embolization in three and intenal carotid artery balloon occlusion in two. The Clinical manifestations, imaging data, choice of treatment, clinical efficacy, follow-up data and literatures were analyzed to discuss the indications for three treatments. Results There was no cerebral ischemia or surgically-related complication. No epistaxis occurred. The eyeball protrusion restoration was found in three patients and intracranial bruit vanishing in three. Vision was improved one patient after half a year follow-up. The pupils shrank in three patients during follow - up. Digital subtraction angiography (DSA) showed no recurrence of pseudoaneurysm. Conclusions Endovascular treatment is the preferred choice of treatment for traumatic carotid artery pseudoaneurysm. The occlusion or parent artery balloon occlusion can be used when the pseudoaneurysm is combined with CCF. Coil embolization can be used for shoes with narrow neck, stent technology combined with coil embolization for those with wide neck and the covered stent for the rock section of the internal carotid artery.
