Switching Mechanism At 5′ end of the RNA Transcript(SMART)is a technology used in biology researching,So far,there is no review only about SMART technology.So,the aim is to investigate the research developments of principles,methods and applications of the SMART technology.Based on some researches and combined with the review of the related literature at home and abroad,it analyzed and evaluated the latest development of the research on SMART.As the applications of the SMART technology expand in many fields day after day,it has been proved that the SMART technology is a very useful and efficient skill to construct full length cDNA library.As more and more researchers know this technology,the advantages of the SMART technology become obvious,and meanwhile the disadvantages of the SMART technology also show up.That is to say,the technology needed to be improved.

Objective To study the inhibitory effects of stachyose on the hyperacute rejection in pig-to-human heart xenotransplantation.Methods A pig-to-human xenogeneic heart transplantation model was established based on an in vitro free heart blood perfusion system.The pig hearts were di- vided into two groups:group A(pig hearts treated with human blood perfusion as control)and group B(pig hearts treated with human blood plus stachyose perfusion).After perfusion for 1h,the heart xenografts were examined for deposit of lgG and IgM by immunohistochemistry and pathological analy sis.Results The mean survival time of perfusion hearts in groups A and B was(9.5?2.5)min and (46.8?8.1)min respectively(P

Objective To investigate the correlation between cerebral artery stenosis (MCAS) and mild cognitive impairment (MCI).Methods Continuous selected 636 cases of 50-80 years old inpatients or outpatients who examined by transcranial color Doppler ultrasound (TCD) in April 2012 to April 2013 in our hospital.Keep the mini-mental state examination (MMSE) and clinical dementia rating (CDR) as the evaluation of cognitive function.Results Detected 124 cases of MCAS patients (MCAS group) and 512 cases of non-MCAS patients (non-MCAS group).Forty-four cases MCI were detected in MCAS group with the prevalence rate was 35.5％(44/124),and 114 cases of patients with MCI were detected in non-MCAS group with the prevalence rate was 22.3％ (114/512),the difference was statistically significant (P ＜ 0.05).Single factor analysis showed that there were no significant difference between two groups in waist circumference,hypertension,coronary heart disease,hyperlipidemia,smoking,diastolic blood pressure and total cholesterol,uric acid,fasting glucose,C-reactive protein (P ＞ 0.05); There were significantly different between two groups in age,gender,education level,MCAS,history of diabetes,systolic blood pressure and triglyceride,low density lipoprotein-cholesterol,high-density lipoprotein-cholesterol(P ＜ 0.05).Multiple factors analysis showed that the MCAS (OR =1.899,95％ CI 1.224-2.946),history of diabetes (OR =1.764,95％ CI 1.191-2.612),systolic blood pressure(OR =1.012,95％ CI 1.003-1.022),gender (OR =0.558,95％ CI 0.380-0.821),and age (OR =1.029,95％ CI 1.010-1.049) was the independent risk factor for MCI.Conclusion The MCAS related with MCI occurrence and development.

Objective To evaluate the clinical efficacy of MRA in the arteries of the pelvis and lower extremity with automatic table movement (MobiTrak).Methods 12 cases suspected of pelvis and lower extremity artery diseases underwent dynamic 3D contrast enhanced MRA and automatic table movement at the same time.Three cases underwent artery angiography,four cases were detected by operation.Results All diseased arteries were well demonstrated.Among them,lower extremity artery occlusion 8,failing vascular grafts 2,artery aneurysms 2.Conclusion Automatic table movement is of value in assessing pelvis and lower extremity artery diseases accurately.And it is a reliable and potential new technique.

Objective To evaluate the effects of nerve growth factor-beta (NGF-β) pretreatment on cell apoptosis induced by endoplasmic reticulum stress during ischemia-reperfusion in isolated rat hearts.Methods Male Sprague-Dawley rats,weighing 180-220 g,were anesthetized with intraperitoneal 10％ chloral hydrate 300 mg/kg.The hearts were excised and perfused in a Langendorff apparatus with K-H solution aerated with 95％ O2 and 5％ CO2 at 37 ℃.Thirty-two isolated rat hearts were randomly divided into 4 groups (n =8 each) using a random number table:control group (group C),I/R group,NGF-β pretreatment group (group N) and NGF-β combined with K252a (trkA receptor antagonist) pretreatment group (group N + K).In group C,the hearts were continuously perfused with K-H solution for 195 min.The hearts were perfused with K-H solution for 45 min in group I/R.In N and N + K groups,the hearts were perfused with K-H solution for 15 min,and then with K-H solution containing 0.1 μg/ml NGF-β and 0.1 μg/ml NGF-β mixed with 100 nmol/L K252a,respectively,for 30 min.The perfusion was suspended for 30 min followed by 120 min of reperfusion with K-H solution in I/R,N and N + K groups.HR,left ventricular end-diastolic pressure (LVEDP),left ventricular developed pressure (LVDP) and + dp/dtmax were measured at the end of 15 min equilibration (baseline) and at 5,30,60 and 120 min of reperfusion.Myocardial specimens were obtained at 120 min of reperfusion for detection of myocardial apoptosis (by TUNEL) and expression of glucose-related protein 78 (GRP78),CCAAT/enhancer-binding protein homologous protein (CHOP),and caspase-12 (by Western blot analysis).Apoptosis index was calculated.Results Compared with group C,HR,LVDP and + dp/dtmax were significantly decreased,and LVEDP,apoptosis index and expression of GRP78 and CHOP were increased in I/R and N groups,and the expression of caspase-12 was upregulated in I/R group.Compared with group I/R,HR,LVDP,and + dp/dtmax were significantly increased,and LVEDP,apoptosis index and expression of GRP78,CHOP and caspase-12 were decreased in group N,and the expression of GRP78 was down-regulated in group N + K.There was no significant difference in cardiac function indexes between group I/R and N + K.Compared with group N,HR,LVDP and + dp/dtmax were significantly decreased,and LVEDP,apoptosis index,and expression of GRP78,CHOP and caspase-12 were increased in group N + K.Conclusion NGF-β pretreatment can protect the isolated rat hearts against ischemia-reperfusion injury,and inhibition of the endoplasmic reticulum stress-triggered cell apoptosis after activating trkA receptors is involved in the mechanism.

Objective: To explore the relationship between lower extremity atherosclerosis disease (LEAD) and cardiovascular risk factors in elder people.
Methods: A total of 700 consecutive patients receive lower extremity Color Doppler ultrasound in our hospital from 2013-05 to 2014-11 were investigated. The patients were divided into 3 age groups: Young and middle group, n=83, Elder group, n=377 and Senile group, n=240. Based on ultrasound scoring system, the patients were divided into 4 groups: Normal group, n=112, Mild atherosclerosis (Mild) group, n=81, Moderate group, n=466 and Severe group, n=41. The cardiovascular risk factors among different groups were compared.
Results: Multivariate unconditional logistic regression analysis showed that age, smoking, history of diabetes, uric acid (UA), ankle-brachial index (ABI) were the independent risk factors for LEAD (B=0.144, 1.496, 0.963, 0.004, -2.510; 95% CI: 1.120-1.190, 2.257-8.824, 1.456-4.716, 1.001-1.007, 0.012-0.534;P=0.000, 0.000, 0.001, 0.006, 0.009 respectively. Ordinal logistic regression analysis indicated that age, male gender, smoking, ABI, UA, history of hypertension were related to the severity of atherosclerosis (B=0.130, 0.737, 0.592, -3.365, 0.003, 0.735; 95% CI: 0.097-0.162, 0.222-1.252, 0.052-1.132, -4.674 to -2.055, 0.001-0.005, 0.313-1.157;P=0.000, 0.005, 0.032, 0.000, 0.005, 0.001 respectively. Compared with Young and Middle groups, Elder and Senile groups had increased rates of moderate and severe arteriosclerotic lesions; compared with Elder group, Senile group presented the higher incidence of moderate and severe lesions, allP<0.01. With elevated age, the severity score of LEAD increased accordingly,P<0.01.
Conclusion: Lower extremity atherosclerosis lesions were more severe in elder patient, and it was particularly severe in senile patients.
