Objective To detect the distribution of cerebral microbleeds (CMBs) in patients with lacunar infarction (LI) and/or leukoaraiosis (LA) and to analyze the correlation between the CMB related risk factors and cognitive impairment.Methods Thirty-eight patients with LI and/or LA were divided into either a CMB group or a non-CMB group according to the findings of susceptibility weighted imaging.The number of CMB lesions was recorded.Mini-mental state examination (MMSE) and Montreal cognitive assessment (MoCA) were used to conduct cognitive function tests,and the patients were also divided into a cognitive impairment group and a non-cognitive impairment group according to the MoCA scores.The demographic and clinical data in each group were compared.The independent risk factors for CMBs and cognitive impairment were identified.Results Thirteen patients had 58 CMBs in the CMB group.Their distributions were as follows:36 CMBs in basal ganglia and thalamus,14 in cortical and subcortical regions,3 in brain stem,and 5 in cerebellum.There were 25 patients in the non-CBM group,26 in the cognitive impairment group,and 12 in the non-cognitive impairment group.There were significant differences in age and the proportions of hypertension,taking antithrombotic drugs and the patients with LA between the CMB group and the non-CMB group (all P ＜ 0.05).Multivariable logistic regression analysis showed that only age was an independent risk factor for CMBs (odds ratio 1.103,95％ confidence interval 1.034-1.454; P =0.045).MMSE (26.92±2.87vs.29.00± 1.44; t=2.452,P=0.027) and MoCA (21.62±3.36vs.25.04 ± 2.59; t =-3.493,P =0.001) scores in the CMB group were significantly lower than those in the non-CMB group.There was only significant difference in the number of CMBs between the cognitive impairment group and the non-cognitive impairment group (2.08-± 3.64 vs.0.33 ±0.78; t =-1.629,P =0.010).Multivariate logistic regression analysis showed that only the number of CMBs was an independent risk factor for cognitive impairment (odds ratio,1.534,95％ confidence interval 1.100-2.576; P=0.046).Spearman rank correlation analysis showed that the number of CMBs was significantly negatively correlated with the MoCA language (r =-0.229,P=0.003) and the delayed recall (r =-0.332,P=0.042) scores.Conclusions In patients with LI and/or LA,CMBs were correlated with age.Their existence and number were associated with cognitive impairment.

Objective To explore the intrinsic link between neuro-endocrine-immune (NEI) network and the viscera-state.Methods Using three databases namely TCM database, Chinese pharmacy database and combination of TCM and WM database in China Academic Journals Database, the authors searched and collected NEI-related indicators published on journals for the viscera-state researches. Then a related database was established for data mining. Through analysis of association rules, analysis of the relationship among diseases, syndromes, therapeutic principles, combination of disease and syndrome, and NEI network related indicators were performed for association rules and directional network diagrams.Results Through the association analysis, the authors drew 44 directional network diagrams of high-frequency disease positions, syndromes, therapeutic principles and NEI network related indicators, and obtained 19 association rules. Kidney and liver essence research focused on HPG axis, HPA axis, and HPT axis. Spleen essence research focused on brain-gut peptide related indicators. Heart essence research focused on vascular endothelium function indicators. Pulmonary essence research focused on humeral immunity, ET and TNF-α.Conclusion It was feasible to explore the intrinsic link between NEI network and the viscera-state by using data mining. Differences among study on NEI network of five-organs systems were found, which is of great significance for researches on the essence of the viscera-state.

Objective To analyze drug resistance of pathogenic bacteria from the blood culture and distribution in clinical departments,and to guide the rational clinical drug use.Methods We retrospectively analyzed 11 275 samples of blood cultures in The Central Hospital of Wuhan from 2012 to 2014.The blood specimens were cultured by VersaTREK(USA).The pathogenic bacteria were identified and their drug resistance was analyzed by BD-PHOENIX 100 automicrobiological identification systems(USA).Results Among the 11 275 blood cultures,636 bacterial strains were detected.The top four bacterial strains were Escherichia coli,Staphylococcus aureus,Klebsiella pneumonia and Enterococcus f aecium.A vancomycin-resistant Enterococcus faecium strain and a pandrug-resistant Klebsiella pneumoniae strain were detected.The top three clinical departments with distribution of pathogens were Gastroenterology Department,Nephrology Department and Intensive Care Unit (ICU).Pathogens isolated from ICU were evenly distributed.Conclusion Distributions of pathogenic bacteria in the blood culture are different in clinical departments.Identification of pathogenic bacteria and result of drug susceptibility can reduce use of broadspectrum antimicrobials and enhance antimicrobial de-escalation.
