Executive function is an important advanced cognitive process, and it is the function that integrates different cognitive processes to achieve one's aim. Updating is an important component of executive function. According to the classifications of Miyake & Colletee on executive function, two study paradigms on memory updating are discussed: n-back paradigm & running memory paradigm. A new study method called latent variable analysis and new studies of cognitive neuroscience on memory updating are introduced. Issues on ethics and morality in research on cognitive experiment of psychology are briefly demonstrated to explore appropriate direction for research of executive function in future.

BACKGROUND: Cirrhosis can cause severe effect on spinal cord or other tissue and organ sometimes.OBJECTIVE: To establish cirrhosis model with rat liver injured by tetrachloride so as to investigate the distribution of nitric oxide synthase (NOS)in spinal cord of rats with cirrhosis.DESIGN: Completely randomized controlled study.SETTING: Anatomy Department of Capital University of Medical Sciences.MATERIALS: The experiment was completed at the Anatomy Department of Capital University of Medical Sciences from March 2002 to December 2003. Totally 20 male Wistar rats were divided randomly into cirrhosis group and normal group with 10 in each group.METHODS: Cirrhosis model in cirrhosis group was established with rat liver injured by tetrachloride, but rats in normal group were not treated with any method. After 3 months, total rats in the two groups were perfused and fixed; meanwhile, tissue of spinal cord was taken out for section.Quantity and gray degree of NOS positive cell in spinal cord of rats with cirrhosis were measured with nicotinamide adenine dinucleotide hydrogen phosphate-diaphorase (NADHP-d) histochemical method and Leica Q500IW image analysis system.MAIN OUTCOME MEASURES: [1] Gray degree of NOS positive neurons of rats in the two groups; [2] Distribution of NOS positive cell of rats in the two groups.RESULTS: Twenty rats all entered the final analysis. [1] Gray degree of NOS positive neurons of rats in the two groups was 60 (P ＞ 0.05). [2] In the area of gray matter of spinal cord, NOS positive cells were mainly distributed over the circumference of central canal, i.e. the Ⅹ layer of spinal cord and intermediolateral nucleus. Color of NADHP-d was positive, and the cellular form was shaped in triangle and fusiform. Cellular nucleus was not colored but color of cytoplasm was deep. The size of cells was moderate mainly of 25 μm. NOS positive cells were generally distributed averagely over intermediate zone of gray matter in cervical, thoracic and lumbar spinal cord and had no specific changes.CONCLUSION: Expression of NOS in spinal cord of rats in the cirrhosis group and the normal group is probably identical. Distributive characteristics of nitrogen monoxide (NO) in spinal cord suggest that adjustment on low sympathetic nerve of rats with cirrhosis is not different from that of the normal.

Objective To evaluate the value of three-dimensional color power angiography(3D-CPA,) in osteosarcoma diagnosis. Methods Forty-three cases with osteosarcoma were detected with 3D-CPA to assess the vascular classification(3D-CPA Ⅰ to Ⅲ) and measure the vascular parameters including vascularization index(VI), flow index(FI) and vascularization-flow index(VFI). Results All of the 43 cases were classified into 3D-CPA Ⅲ type. The space structure shape of blood vessels and the origin of nutrient vessels was clear. The quantitative measurement showed that VI was 25.84±6.87,FI was 34, 18±2.93, VFI was 9.02±4.04. Conclnsions It is a new method to analyze and diagnose osteosarcoma with 3D-CPA because it can show the nutrient vessels and the embranchments of blood vessels clearly, tridimensionally and integrally and Bake quantitative or partial-quantitative analysis.

Through literature retrieval, the effects of transcutaneous electrical acupoint stimulation (TEAS) in peri-anesthesia period are summarized. It is found out that TEAS can reduce anesthetics consumption, relieve stress reaction of surgery, stabilize patients' hemodynamics, reduce surgical complication and improve immune function and quality of recovery; besides, it has protective function on heart, brain, liver, stomach, intestines and so on. However, except certain analgesic effect, the sham TEAS and transcutaneous electrial nerve stimulation do not have other functions of TEAS. The acupoint selection and stimulation parameter of TEAS in assisting anesthesia are still needed be improved and united.

To investigate the changes of drug resistance of pseudomonas aeruginosa ( PA) to common antimicrobial agents in recent 3 years in Anhui province. The average drug resistance rate was 15. 3%, 17. 0% for piperacillin/tazobactam, amikacin respectively, while the average resistance rate was higher for the third generation cephalospo-rin cefotaxime, ceftriaxone and ceftizoxime, which was between 42. 0% and 55. 0%. The average drug resistance rate was 25. 2% for imipenem. The resistance rates for ceftazidime, cefepime, ceftriaxone and ceftizoxime were sig-nificantly increased( P<0. 05 ) . The resistance of PA to the third generation cephalosporin and ciprofloxacin in-creased gradually, close attention should be paid to it in clinical practice.

The prevalence rate of diabetes is continuously increasing in China, and diabetes characterizes as high morbidity, low diagnostic rate, low cure rate, and low good control rate, which consequently resultes in the occurrence and progression of various diabetic complications and dramatically decreases the quality of life as well as the survival of diabetic patients.So it is crucial for clinician to screen diabetes early, make the diagnosis early, and start the treatment promptly.This article systemically summarizes the clinical manifestations, diagnostic criteria, typing, pathophysiology, complications, and management of diabetes.

BACKGROUND:CT perfusion technology is a common non-invasive detection method, which can be used to quantitatively determine the ischemia severity and range at early stage of cerebral infarction and then judge whether ischemic brain tissues can survive or recover. OBJECTIVE:To assess the neurological function recovery of cerebral infarction rats undergoing neural stem cel transplantation using CT perfusion imaging. METHODS:A total of 60 Sprague-Dawley rats were randomly divided into control group, cerebral infarction group, transplantation group, with 20 rats in each group. Rat model of middle cerebral artery occlusion was made in the latter two groups. After 24 hours of modeling, PBS and 8×105 neural stem cels were administratedvia the tail vein into the rats in the cerebral infarction and transplantation groups, respectively. CT perfusion-weighted imaging was performed at 1, 3, 7, 14, 28 days after transplantation. Modified neurological severity scores were recorded at 1, 2, 3, 4 weeks after transplantation. Triphenyltetrazolium chloride staining was used to calculate infarct volume at 4 weeks after transplantation. Hematoxylin- eosin staining was adopted to observe pathological changes of brain tissues at 2 weeks after transplantation. RESULTS AND CONCLUSION: There were no abnormal hemodynamic changes in the control group at different time points. The transplantation group exhibited an increasing CT value with time, and the increased cerebral blood flow could improve the survival rate of neurons in the ischemic penumbra. The modified neurological severity score and infract volume in the transplantation group were both significantly lower than those in the cerebral infarction group (P < 0.05). Cel necrosis was improved obviously in the transplantation group. These results show that CT perfusion imaging can be used to observe the neurologic function recovery of cerebral infarction rats in aspects of morphology and hemodynamics.
