Objective To introduce a new intelligent stomach syringe based on PC,which can deal with the stop of waste pipe automatically and feed back to the control of water speed.Methods On the foundation of analyzing the defects of traditional stomach syringe,the electric circuit of the design was improved.It realized the judgment,analysis and handling of acquired signals in the PC board.Results This machine can display the numerical value of pressure,PH,flux,and give the sound or light alarm.It can work automatically according to the demand or be operated artificially.Conclusion The instrument is automatic,secure and intelligent.Furthermore,it increases the successful rate for rescuing the patients.

AIM:To explored the potential role of HIF-1? in reducing the neuronal apoptosis and promoting the neuronal proliferation after stroke in rats. METHODS:The bone marrow-derived mesenchymal stem cells (BMSCs) were lentivirally transduced to express the stable form of HIF-1?. Ischemic stroke was induced by permanent middle cerebral artery occlusion (MCAO) in Sprague-Dawley rats. Neurological function was evaluated by modified neurological severity score (mNSS). Cerebral infarct volume was measured by TTC staining. Immunohistochemistry and terminal deoxynucleotidyltransferase mediated dUTP nick end labeling (TUNEL) method were performed to detect neuronal proliferation and apoptosis. RESULTS:Significant improvement of neurological deficits was found in BMSCs-mHIF-1? rats as compared to the control animals at 14th d and 28th d after MCAO (P

AIM: To explored the potential role of HIF-1α in reducing the neuronal apoptosis and promoting the neuronal proliferation after stroke in rats. METHODS: The bone marrow-derived mesenchymal stem cells (BMSCs) were lentivirally transduced to express the stable form of HIF-1α. Ischemic stroke was induced by permanent middle cerebral artery occlusion (MCAO) in Sprague-Dawley rats. Neurological function was evaluated by modified neurological severity score (mNSS). Cerebral infarct volume was measured by TTC staining. Immunohistochemistry and terminal deoxynucleotidyltransferase mediated dUTP nick end labeling (TUNEL) method were performed to detect neuronal proliferation and apoptosis. RESULTS: Significant improvement of neurological deficits was found in BMSCs-mHIF-1α rats as compared to the control animals at 14th d and 28th d after MCAO (P<0.05). Significant reduction of infarct volume was observed in rats in BMSCs-mHIF-1α group at 3rd day after MCAO (P<0.05). Histological evaluation showed that BMSCs-mHIF-1α treatment significantly promoted neuronal survival and proliferation in the ischemic boundary area. CONCLUSION: Constitutive expression of HIF-1α in BMSCs reduces the neuronal apoptosis and promotes the neuronal proliferation after stroke in rats.

Objective To compare the changes of plasma lipid indexes and coronary artery atherosclerotic plaque in TaqI B genotypes in CHD patients with impaired glucose tolerance (IGT) before and after statin therapy. Methods A total of 196 CHD with IGT and 160 controls were included. The changes of plasma lipid indexes and coronary artery atherosclerotic plaque in TaqI B genotypes were analyzed before and after Rosovastatin therapy. Sequenom Mass ARRAY platform was used to detect the CETP TaqI B SNPs. Results The genotype frequency of the B1B1, B1B2 and B2B2 in CHD with IGT group was 35.7%, 48.0% and 16.3% respectively, while in control group was 31.3%, 53.1% and 15.6% respectively. HDL-C, PA and MLA levels increased after Rosuvastatin therapy, while LDL-C, TG, TCH, Lpa, PA, EEMA and PB levels decreased. Conclusions CETP gene polymorphisms TaqI B would have association with the effects of Rosuvastatin therapy in the CHD with IGT.

Objective To study the characteristics and clinical significance of the coronary plaques in patients with benign prostatic hyperplasia (BPH).Methods A total of 91 patients undergoing coronary artery angiography (CAG) were selected and divided into two groups according to with or without BPH,56 cases in BPH group,46 cases in control group.The qualitative and quantitative characteristics of 102 lesions area were analyzed by intravascular ultrosound (IVUS),including external elastic membrane-cross-sectional area (EEM-CSA),minimal lumen area (MLA),plaques area (PA),plaques burden (PB),reference external elastic membrane-cross-sectional area (REEM-CSA),reference minimal lumen area (RMAL),reference plaques area (RPA) and reference plaques burden (RPB).Results IVUS showed a higher rate of area stenosis than did the CAG [(58.2± 7.1)％ vs.(55.9 ± 5.2)％,P＜0.01].BPH group had more soft plaques,eccentric plaques,positive remodeling and less calcified than did the control group (P＜0.05).The MLA and RMAL of BPH group were smaller than those of control group:MAL [(5.61±0.96) mm2 vs.(6.06±0.75) mm2,P＜0.05],RMAL[(9.26±1.05) mm2 vs.(10.02±1.10) mm2,P＜0.05]； while the EEM-CSA,PA,PB,RPA,RPB were larger than those of control group:EEM-CSA[(14.51±1.10)mm2 vs.(13.37±1.02)mm2],PA[(8.90±1.24) mm2 vs.(7.31±1.04) mm2],PB[(61.26±6.53)％ vs.(54.53±5.69)％],RPA[(4.26±1.15) mm2 vs.(3.73±1.33) mm2],RPB [(31.30±8.37) ％ vs.(26.81±8.75) ％,P＜0.05].Conclusions IVUS has a higher value on evaluation of mild to moderate coronary artery stenosis.Evidence of myocardial ischemia in patients with BPH needs further excludeing coronary heart disease.
