Objective This study aimed at the effect of glutamate(Glu) on rat cortical pyramidal cells in cultured brain slices treated by threohydroxyaspartate(THA),an inhibitor of glutamate transporter.Methods The brain slice cultures were prepared using 1-day-old rat.Various concentrations of THA(50,100 and(500 ?mol/L))were added into the culture medium respectively.Cortical pyramidal cells' survival was evaluated by immunohistochemistry staining monoclonal antibody SMI-32,a nonphosphorylated neurofilament marker,Glu level in the culture medium was also measured.Ultrastructural picture of neuropathology were examined by EM microscopy. Results The brain slices in the control group maintain excellent organization and a stable population of pyramidal cells.THA caused a slow dose-dependent loss of cortical pyramidal cells and an increase of Glu level in the culture medium.THA of 100 ?mol/L resulted in a significant decrease in cortical pyramidal cells after culturing for 5 weeks.Pyramidal cells appeared vacuolar degeneration.Conclu-(sions Extra-cellular) Glu caused chronic excitotoxicity to cortical pyramidal cells.

OBJECTIVE To investigate the clinical distribution characteristics and drug resistance of pathogens in hematology department ward during recent two years,and instruct clinical application of antibiotics reasonably.METHODS The bacteria were identified by VITEK-60 with GNI+,GPI and YBC.Drug sensitivity tests of bacteria were performed by K-B method.The results were analyzed by WHONET 5.3 software.RESULTS The results showed that 370 strains of pathogens were isolated from all detected samples.The composition ratio of Gram-positive bacteria,Gram-negative bacteria and fungi was 59.7%,32.4% and 7.8%,respectively.Coagulase negative Staphylococcus,Escherichia coli,Pseudomonas aeruginosa,Klebsiella pneumoniae and Acinetobacter baumannii were the most frequently isolated pathogens.The ESBLs producing strains in E.coli and Klebsiella spp were 59.3% and 24.2%,respectively.The MRSA in S.aureus and MRCNS in coagulase negative Staphylococcus were 18.2% and 87.8%,respectively.CONCLUSIONS Inspecting pathogens and studying the trend of their drug resistance are important to rationally select antibiotics,reduce infection incidence and mortality rate,and decrease the occurrence of drug resistant strains.

Objective: To study the inhibitory effect of VEGF antisense oligonucleotides (ASODN) on growth of Lewis lung cancer in C57BL/6 mice.Methods: Lewis lung cancer cells were cultured and implanted subcutaneously into 40 C57BL/6 mice, which were then divided into 4 groups: VEGF-ASODN treatment group, VEGF-SODN treatment group, BEGF-MODN treatment,and control group (normal saline). Mice in different groups were treated 24 hours after cell inoculation. The weight and volume of subcutaneous tumors was measured and the morphological changes of tumor cells was observed under microscope. VEGF protein and microvessel density were examined by immunohistochemistry.Partial tumor tissues were kept in liguid nitrogon.Results: The average tumor weights of the control, VEGF-ASODN, VEGF-SODN and VEGF-MODN groups were (7.33?0.71)g, (4.56?0.38) g, (7.59?0.32) g, and (7.62?0.39) g, respectively. The inhibition rates of tumor growth in VEGF-ASODN, VEGF-SODN and VEGF-MODN group were 43.8%, 5.5% and 3.1%, respectively. VEGF-ASPODN obviously inhibited the tumor cell growth and decelerated the tumor cell proliferation. Immunohistochemistry results showed that the expression of VEGF in ASODN group was remarkly lower than those in SODN group, MODN group and control group (P

Signal transducer and activator of transcription 3(STAT3)is an important member of STATs family and is highly expressed in many kinds of cancer.It regulates the tumor growth by influencing the apoptosis of tumor cells and tumor angiogenesis and becomes a new target for tumor therapy.This article reviews the structure of STAT3,the stimulating factors of STAT3,the tumor growth regulating pathway of STAT3,and its potential as a target for tumor therapy.

Mycoplasma pneumoniae(MP) is the smallest organism that dose not need a host cell for replication.It is one of the most common pathogens of community acquired pneumonia in children.In recent years,the incidence of pneumonia mycoplasma pneumonia increased year by year,and severe pneumonia mycoplasma pneumonia,refractory pneumonia mycoplasma pneumonia cases also increased.MP causes a variety of clinical presentations,in addition to respiratory infections,there are also many extrapulmonary manifestations.Immune response plays a very important part in pathogenesis of MP infection.This article focused on the immune aspects in pathogenesis and extends to some diagnosis and therapeutic implications.

Objective To study the value and the superiority of multi-slice spiral CT angiography of pulmonary artery in combination with deep vein of lower limb in diagnosing pulmonary embolism (PE). Methods CT pulmonary angiography (CTPA) and lower limb deep vein venography were performed in all suspected patients of PE with single or multi-slice spiral CT.The number and type of the embolus were calculated.Results Among the 44 patents of pulmonary embolism,34 patents had both PE and deep vein thrombo embolism (DVT) ,10 patients had only PE.The total ratio of the PE diagnosed with single slice spiral CT and multi-slice spiral CT was 12.1% and 19.0%, respectively , there were statistical significance, (P=0.004); the ratio of the PE upon deuto-segment pulmonary arteries was 25.3% and 29.7%, respectively, there was no statistical significance, (P=0.104); the ratio of the PE below deuto-segment pulmonary arteries was 1.1% and 10.2%, respectively, there was statistical significance, (P=0.000).Conclusion The technique of angiography of pulmonary artery in combination with deep vein of lower limb in diagnosing PE is a non-invasive, fast, sensitive and specific method for PE. Multi-slice spiral CT is superior to single slice spiral CT in the diagnosis of PE.
