4.Effect of atorvastatin on ADAM10 in hippocampus of chronic cerebral hypoperfusion in rats
International Journal of Cerebrovascular Diseases 2011;19(10):781-785
Objective To investigate the learning and memory functions,expression changes of disintegrin and metalloprotease 10 (ADAM10) mRNA in hippocampus in the aged rats with chronic cerebral hypoperfusion as well as the effect of atorvastatin on them.Methods A total of 72 rats were randomly divided into sham operation,cerebral hypoperfusion and atorvastatin treatment groups.A permanent bilateral common carotid artery occlusion (2VO)model was induced.Atorvastatin 10 mg/(kg · d) was administered orally after procedure in the atorvastatin treatment group.Real-time fluorescence quantitative polymerase chain reaction was used to detect the expression of ADAM10 mRNA in bilateral hippoocampus at 1,2,4,and 16 weeks after modeling,Results Two weeks after modeling,the learning and memory functions were decreased significantly in the cerebral hypoperfusion group compared to the sham operation group (P < 0.05).At 4 and 16 weeks after modeling,they were further decreased (P <0.01); there were no significant differences in the learning and memory functions at 1,2,and 3 weeks after modeling between the atorvastatin treatment group and the cerebral hypoperfusion group,however,they were improved significantly at 16 weeks compared to the cerebral hypoperfusion group (P<0.01).The expression of ADAM10 mRNA in hippocampus at different time points after modeling in the cerebral hypoperfusion group was down-regulated by 22%,43%,35%,and 50%,respectively compared to the sham operation group (all P <0.05).The expression of ADAM 10 mRNA in hippocampus at 2 weeks in the atorvastatin treatment group was higher than 22% in the cerebral hypoperfusion group (P<0.05).There were not significant differences at other time points.Conelusions Chronic cerebral hypoperfusion results in the down-regulation of the expression of ADAM10 mRNA in hippocampus in the aged rats,and atorvastatin may inhibit down-regulation of the expression of ADAM10 mRNA at early stage.
5.Extraction method of the magnetoencephalography somatosensory evoked signals based on the MP decomposition
China Medical Equipment 2014;(5):48-51
Objective:Matching pursuit algorithm(MAP),for its good parametric characterization, is applied in Magnetoencephalography(MEG) to study time-frequency distribution. Methods:This paper proposes to apply a high-resolution time-frequency analysis algorithm, the matching pursuit (MP), to extract detailed time-frequency components of SEF signals. Results: Experimental results on cortical SEF signals of several normal subjects show that a series of stable SEF time components can be identified using the MP decomposition algorithm. Conclusion:This study shows that there is a set of stable and minute time-frequency componentsin SEF signals, which are revealed by the MP decomposition. These stable SEF components have specific localizations in the time domain and may provide a reliable index for clinical research of brain function and brain disease pathogenesis.

International Journal of Cerebrovascular Diseases 2006;0(10):-
Rehabilitation treatment after cerebral infarction establishes on the basis of plastic changes in the central nervous system,which can compensate the functions lost in the affected brain regions.Neurorehabilitation training realizes neurological function recovery partly by enhancing cortical reorganization.Repetitive transcranial magnetic stimulation (rTMS) is a non-invasive approach that can effectively improve the cortical excitability,This article reviews the application of rTMS in the clinical studies of motor function recovery in patients with hemiplegia after cerebral infarction.
7.An analysis of clinical characteristics of septic acute kidney injury by using criteria of Kidney Disease: Improving Global Outcomes
Chinese Journal of Internal Medicine 2013;(4):299-304
Objective To evaluate the value of Kidney Disease:Improving Global Outcomes (KDIGO) criteria in investigating clinical feature and prognosis of acute kidney injury (AKI) patients with sepsis in ICU.Methods Clinical data of patients with AKI defined by KDIGO criteria in ICU of Wuxi People's Hospital from June 2007 to June 2012 were collected.Clinical characteristics,prognosis and major risk factors of death of septic AKI patients were retrospectively analyzed.Results Of the enrolled 703 AKI patients,395 (56.2%) were caused by sepsis (septic AKI),which indicated that sepsis mainly contributed to the causes of AKI.For septic AKI stratified by KDIGO classification,146(37.0%) patients belonged to AKI Ⅰ,154(39.0%) to AKI Ⅱ,and 95 (24.1%) to AKI Ⅲ.Compared with the patients with non-septic AKI,septic AKI patients had greater APACHE Ⅱ and SOFA score (25.1 ±4.9 vs 20.5 ±6.4,12.9 ±2.6vs 10.4 ± 4.5 ; all P values < 0.05).Although there was no significant difference in baseline serum creatinine [(82.9 ± 22.2) μmol/L vs (83.1 ± 30.O) μmol/L,P > 0.05] between the two groups,patients with sepsis had higher serum creatinine [(143.5 ± 21.6) μmol/L vs (96.2 ± 15.5) μmol/L; P < 0.05],a higher proportion fulfilled KDIGO categories for both AKI Ⅱ and Ⅲ (63.0% vs 33.1% ; P < 0.05),a higher renal replacement therapy (RRT) rate (22.3% vs 6.2% ; P < 0.05) and a lower proportion of complete renal recovery(74.4% vs 82.8%) (all P values < 0.05).The 90-day mortality of septic AKI patients was higher than that of non-septic AKI patients (52.2% vs 34.1% ; P < 0.05).Septic AKI,graded by KDIGO,was associated with an increased mortality.Logistic regression analysis showed that APACHE Ⅱ score (OR =5.451,95% CI:3.095-9.416),SOFA score (OR =2.166,95% CI:1.964-4.515) and RRT (OR =4.021,95% CI:2.975-6.324) were independent risk factors for mortality of septic AKI patients.Conclusion Septic AKI patients have a higher burden of illness,worse renal function and higher mortality.APACHE Ⅱ score,SOFA score and RRT are independent risk factors to septic AKI mortality.
8.Variance and resource of intracellular free calcium and extracellular arachidonic acid of host cells during the invasion of Toxoplasma gondii
Chinese Journal of Infectious Diseases 2008;26(4):211-216
Objective To explore variance and resource of intracellular free Ca2+ and extracellular arachidonic acid (AA) in different types of passage cells during the invasion of T. gondii. Methods The variance and resource of extracellular AA and intraceUular free Caz+ of Vero and J774A. 1 cells during the invasion of T. gondii were detected by multi-purpose scintillation counter and laser scanning confocal microscope. Data were analyzed using Chi-square test and t test. Results The intracellular free Ca2+ levels in J774A. 1 and Vero cells were both increased after T. gondii infection. The maximal changes of fluorescence intensity were (1 219.7±58.4)% (P<0.01) and (356.3±23.6)% (P<0.05), respectively.The increase of intracellular Ca2+ level in Vero cell was mostly from the release of intracellular Ca2+ store.And the Ca2+ increase in J774A. 1 cell was from both the release of intracellular Ca2+ store and extracellular Ca2+ influx. Extracellular AA levels were significantly increased in both Vero and J774A. 1 cells after T.gondii infection 5.02 and 8. 44 times respectively (t= 3. 124, t = 3. 852, P<0.01). The AA elevations could be significantly inhibited by phospholipase A2 (PLA2) inhibitor pretreating T. gondii. Conclusions The phospholipase C of phagocytic host cell and PLA2 of T. gondii are activated by T. gondii infection,which results in the increase of intracellular free Ca2+ and extraeellular AA level. Combined actions of Ca2+and AA play a major role in the invasion of T. gondii to host cell. While only PLA2 of T. gondii may be activated in nonphagoeytic host cell.
