Objective To evaluate the safety and effect of percutaneous fenestration of intimal flap(FIF) and endovascular stent(ES) placement for aortic dissection. Methods Male patient, 54 years old. DeBakey Ⅲb aortic dissection, tear of intimal flap situated at the beginning of desconding aorta, developed to abdominal aorta and right iliac artery. The true lumen was 3 mm at narrowest locatation. Through femoral artery approach, percutaneous fenestration of intimal flap and ES placement are operated and four ES were placed. Results The blood flow of aortic true lumen and branches were resumed. The true lumen raised to 12 3 mm at the narrowest locatation. The clinical symptoms vanished. Conclusion Percutaneous fenestration and ES placement for aortic dissection feature little injure, high safety and effecacy. So, It is the first choice for certain aortic dissection.

With the advanced development of information technology, there is a huge impact on various industries for the arrival of big data. In the biomedical field, innovative genome sequencing technology enables low-cost, high-throughput, and high-speed to become a reality, which leads to an explosive growth in data and also appeared in an urgent need to process those massive biological information. High performance computing (HPC) along with effective methods is one of the best ways to deal with the problem of big data in biomedical field which could serve the biomedical development best. We discussed the issues faced in biomedical big data processing and concluded that the bioinformatics is an indispensable component of biomedical technologies.

Objective:To evaluate the role of the left ventricular ejection fraction (LVEF) in coronary artery bypass grafting(CABG)patients. Methods: From 2004 to 2005,215 patients underwent CABG and there were 36 cases with LVEF0.40(normal LVEF group). Correlative data of the two groups were compared and analyzed statistically. Results: Compared with the normal EF group, the EuroSCORE of the low EF group was much higher (mean 6.4?1.7) and many more patients of the low EF group had concomitant moderate to severe mitral valve insufficiency and aneurysm that needed simultaneous surgical operation(55.6%).Two patients died in hospital(5.5%)in the low EF group whereas five patients in the normal EF group(2.8%, P

BACKGROUND: This study was undertaken to determine the prevalence of organ failure and its risk factors in patients with severe acute pancreatitis (SAP) . METHODS: A retrospective analysis was made of 186 patients with SAP who were had been hospitalized in the intensive care unit of Jinzhong First People's Hospital between March 2000 and October 2009. The patients met the diagnostic criteria of SAP set by the Surgical Society of the Chinese Medical Association in 2006. The variables collected included age, gender, etiology of SAP, the number of comorbidit, APACHEII score, contrast-enhanced CT (CECT) pancreatic necrosis, CT severity index (CTSI) , abdominal compartment syndrome (ACS) , the number of organ failure, and the number of death. The prevalence and mortality of organ failure were calculated. The variables were analyzed by unconditional multivariate logistic regression to determine the independent risk factors for organ failure in SAP. RESULTS: Of 186 patients, 96 had organ failure. In the 96 patients, 47 died. There was a significant association among the prevalence of organ failure and age, the number of comorbidity, APACHEII score, CECT pancreatic necrosis, CTSI, and ACS. An increase in age, the number of comorbidity, APACHEII score, CECT pancreatic necrosis were correlated with increased number of organ failure. Age, the number of comorbidity, APACHEII score, CECT pancreatic necrosis, CTSI and ACS were assessed by unconditional multivariate logistic regression. CONCLUSIONS: Organ failure occurred in 51.6% of the 186 patients with SAP. The mortality of SAP with organ failure was 49.0%. Age, the number of comorbidity, APACHEII score, CECT pancreatic necrosis, CTSI and ACS are independent risk factors of organ failure.

Objective To investigate the roles of somatostatin(SS)positive intemeurons in the development and compensation of temporal lobe epilepsy.Methods Piloearpine-induced epilepsy rat model was established.Immunohistochemistry method was used to detect number changes and axonal sprouting of SS positive intemeurons in different domains of the hippocampus at difierent time points.Degeneration of SS positive interneurons and their neurophils were detected by the double immunofluorescence staining with SS and Fluoro-Jade B(FJB)at 7 and 60 days after status epilepticus (SE).Results In the exoerimental rat group,the number of SS positive neurons decreased in each hippocampal domain,and it reached the lowest at 7 days post-SE(There were 11.1±3.3 in hilus,2.8±0.9 in CA1region and 1.8±0.7 in CA1region,t=13.519,9.644 and 8.808,all P<0.01).In chronic phase,the number of SS neurons gradually recovered,and exceeded the control group in CA1 area at 60 days post-SE(12.8±1.5 vs 8.8±1.3,t=-4.506,P<0.01),however,the number of SS neurons in the hilus(25.5±4.6)and CA1 area(4.8±0.8)remained significantly less than normal levels(t value were 4.691 and 3.953.both P<0.01).Increased SS positive fibers were found in the lacunosum-molecular (1m)layer and outer molecular layer of dentate gyrus after 30 days post-SE,and numerous SS positive fibers were seen threnghout the layers of area CA1 at 60 days post-SE.Double immunofluuorescence revealed that a few SS positive interneurons and fibers were also labeled by FJB in area CA1 at 7 days post-SE and in CA domain/hilus at 60 days post-SE.Conclusions SS intemeurons loss plays an important role in the development of temporal lobe epilepsy.The loss is partially caIlsed by the degeneration and death of neurons;SS positive neurophils increase within area CA1 in chronic phase may play a significant role in the generation and compensation of temporal lobe epilepsy.

Objective To investigate the current status of type 2 diabetic patients who failed to achieve the glycemic control target, and provide theoretic evidences for making corresponding strategies. Methods The 2 diabetic patients who failed to reach the glycemic target were recruited from 181 hospitals in 26 cities and received a standard questionnaire, the conditions of their blood glucose level, lifestyle intervention, blood sugar monitoring, and drug therapy were recorded. Totally 3 861 questionnaires with complete information were collected. And the causes which account for glycemic control status were analyzed. Results Among these patients, the mean HbA1c was 7.9%, the mean fasting plasma glucose was 8.2 mmol/L, and the mean postprandial plasma glucose was 11.5 mmol/L. Only 25.6% of patients take their diet control strictly as prescribed and 44. 5% of patients have little exercise. 35. 8% and 47.8% of patients did not monitor their fasting and postprandial plasma glucose,respectively. Glycemic control in the patients aged > 60 years was similar to the younger patients, but the hypoglycemia incidence in the elder group reached 35.5%, which was higher than those in the other 2 groups (20.8% and 21.4%, both P<0. 05 ). The proportion of patients with mono-therapy and combination therapy was 46. 1% and 51.7%, while the proportion with combination therapy rose in the patients aged >60 years (58.7%;Compared with the other age-groups, all P<0.05 ). 75 % of patients have adjusted their drug administration regimen since initial treatment. Conclusions Inadequate or inappropriate drug therapy regimen is a major cause responsible for this poor glycemic control status. In addition, the unhealthy life styles, insufficient blood sugar monitoring, and poor compliance were also important causes. Thus, for these patients, it is necessary to further enhance patients' education, to improve life style intervention, as well as to select more effective, safer, and compliant drug therapy regimens. Finally, the glycemic control target for the elder patients should be more flexible.
