BACKGROUND: This study aimed to determine the effects of sepsis on brain integrity, memory, and executive function. METHODS: Twenty sepsis patients who were not diagnosed with sepsis-associated encephalopathy (SAE) but had abnormal electroencephalograms (EEGs) were included. The control group included twenty healthy persons. A neuropsychological test of memory and executive function and a brain magnetic resonance imaging scan were performed. The volumes of cortex and subcortex were measured using the FreeSurfer software. Acute Physiology and Chronic Health Evaluation II (APACHE II) score was used to determine the disease severity. RESULTS: In the sepsis group, the levels of immediate free recall, immediate cued recall, and delayed cued recall in the California Verbal Learning Test-II (CVLT-II) were significantly lower; the explicit memory (recollection process) in the process dissociation procedure test was lower; and the volumes of the left and right hippocampi were significantly lower compared with the control group. The volume of the presubiculum in the hippocampus of sepsis patients showed statistically significant decrease. In the sepsis group, the volumes of the left and right hippocampi were negatively correlated with the APACHE II score and positively with immediate free recall, immediate cued recall, and delayed cued recall in the CVLT-II; moreover, the hippocampal volume was significantly correlated with recollection but not with familiarity. CONCLUSIONS: Patients with abnormal EEGs during hospitalization but with no SAE still have reduced hippocampal volume and memory deficits. This finding indicates that sepsis leads to damage to specific parts of the hippocampus.

Object To solve the problem that Taxus chinensis var. mairei (Lemee et L?vl.) Cheng et L. K.Fu grows slowly. Methods The consumption of phosphorus during the cell suspension culture and the effect of fed-batch carbohydrate, nitrogen and phosphorus on cell growth and living-cell activity were assayed. Results The carbohydrate was exhausted in the middle phase of suspension culture, dificiency of carbohydrate led to inhibition of cell growth in the late culture. Conclusion Compared with the control group, the cell growth rate and the cell density in the fed-batch carbohydrate group were increased significantly, and the cell growth rate was up to 83%.

Objective To study the relationship between hospital attributes and hospital social responsibility (HSR)behaviors,and measures to improve HSR performance.Methods 79 TCM hospitals in Jiangsu Province was surveyed with questionnaires for their HSR performance in 201 1 and 2012,with the data analyzed by independent two-sample t-test.Results In terms of HSR contribution,different levels of hospitals have statistical significance in bad debt,accomplishment of government mandatory missions,environmental protection,education and research,and social welfare activities.Hospitals in different regions have statistical significance in education and research,low-profit medical services and cheap drugs provision.Teaching hospitals make statistical significance in accomplishment of government mandatory missions,environmental protection,education and research,and social welfare activities.In terms of HSR willingness,different levels of hospitals have statistical significance in accomplishment of government mandatory missions,price discount,and education and research.Hospitals in different regions have statistical significance in health services with positive social effects,education and research,and social welfare activities.Teaching hospitals make statistical significance in education and research. Conclusions Secondary hospitals need to invest more resources on HSR.Hospitals in underdeveloped areas must pay more attention to environmental protection,education and research.Non-teaching hospitals need to strengthen quality of care,accomplishment of governmental mandatory missions and environmental protection.

Objective To investigate the correlation between levels of erythrocyte natrium(EN),magnesium(EM),adenosine triphosphate enzyme(Na + K + ATPase,Ca 2+ Mg 2+ ATPase) activity versus urine natrium(UN),urine endogenous digitalis like substances(UEDLS) change in patients with acute cerebral infarction(ACI) Methods 35 patients with ACI were measured in UEDLS,the changes of UN,erythrocyte membrane ATPase activity,and levels EN,EM,and compared with the normal controls Results Levels of UN,UEDLS,EN were significantly elevated( P

Objective To explore the effect of prenatal inflammation on vascular remolding and blood pressure in mid-aged rats.Methods Time-mated pregnant Sprague-Dawley(SD)rats were randomly divided into 2 groups,received peritoneal injection of 0.79 mg/kg LPS on the gestation days 8,10,and 12,or same volume of the sterile saline at the same time points.Nine pups were randomly selected from each group for the later experiments,and the offspring were named as LPS groups for those having prenatal LPS exposure and control group for those having not.Their blood pressure was determined with a rat tail non-invasive instrument by tail-cuff method from 6 weeks old to 35 weeks old,and then their aortas were taken out for media thickness(MT),diameter of lumen(LD),and the ratios of MT/LD.The expression of proliferating cell nuclear antigen(PCNA)on the vessel was detected by ELISA.The serum level of NO and plasma endothelin-1(ET-1)were measured by nitrate reductase and radioimmunoassay respectively.Results Compared with control group,LPS groups had significantly raised blood pressure,a significantly higher ratio of MT/LD,obviously increased expression of PCNA,and markedly elevated serum ET-1.Conclusion The offspring whose prenatal rats were exposured to LPS result in vascular remolding,vasofunctional disturbances and hypertension.

Objective To analyse correlated risk factors of evolving cerebral infarction(ECI).Methods The follow data was recorded in the acute cerebral infarction (ACI)cases when they were admitted :sex,age,systolic blood pressure(SBP),diastolic blood pressure(DBP),history of disease (diabetes mellitus,hypertension,hyperlipidaemia,cerebral infarction,hyperuricemia or smoking).The following examinations or determinations were done,including:white blood cell count (WBC),platelet count (PLT),blood gluconate(GLU),PT-INR,fibrinogen(FG),TT-INR,APTT-INR,C-reactive protein(CRP),D-dimer(D-D),products of fibrin degradation(FDP),anti-thrombin Ⅲ(ATⅢ),apolipoprotein A(apoA),apolipoprotein B(apoB),blood urea nitrogen(BUN),creatinine(CR),triglyceride (TG),high density lipoprotein (HDL),low density lipoprotein (LDL),very low density lipoprotein (VLDL),GOT,lactate dehydrogenase(LDH),creatine phosphokinase (CPK),MB isoforms of creatine phosphokinase (CPK-MB),? hydroxybutyrate dehydrogenase (?-HBDH),troponin I(TnI),cerebral CT or MRI and carotid ultrasonography.The patients were divided into two groups,ECI and completed cerebral infarction (CCI),according whether neurons function scale deteriorated.When cases of both groups exceeded 50,we took statistic test by SPSS10.0 statistic software.Results 8 of the above 46 markers had significant defference between the two groups,including CRP,WBC,apoB,GLU,LDH,CPK-MB,?-HBDH and DBP.ECI was more common in patients who had lower DBP or higher CRP,WBC,apoB,GLU,LDH,CPK-MB,?-HBDH when they were admitted.Conclusion The increase of CRP,WBC,apoB,GLU,LDH,CPK-MB,?-HBDH or decrease of DBP when patients are admitted can be predictive markers of ECI.

To identify the factors that affect the hospital social responsibility(HSR)level based on theoretical analysis.79 TCM hospitals in Jiangsu Province were surveyed with questionnaires,with the data analyzed by the multiple linear regression model.The research results show the following: 1. Hospital’s financial performance,hospital size,and the congress of medical workers are positive factors to the HSR level.2.Pressure from HSR performance of neighboring hospitals has a significant negative impact.3.Hospital’s financial performance and hospital size have a significant positive impact on its intention to fulfill HSR.4.Hospital location has a significant negative impact on its intention to fulfill HSR.

Objective: To observe the interface bonding between the coral and new bone. Methods: The block coral was implanted on rabbit calvaria subperiosteally. The specimens were observed by the scanning electron microscopy 2, 4, 8, 12 weeks after operation respectively. Results: The coral was progressively absorbed and replaced by new bone. The coral bond to bone directly. No intervening layer was found between coral and bone. Conclusion: The coral bond to bone by direct mechanical way. [
