ObjectiveTo investigate the prevalence and the characteristics of heart failure (HF) in medical intensive care unit (ICU) so as to explore the factors contributing to HF.Methods A retrospective analysis of the data of HF was carried out in 887 HF patients (54. 2％ ) males; age (69.83± 13.57) years oldadmitted to the medical ICU from October 2006 through June 2010. Clinical variables were systematically reviewed for all enrolled patients. HF as either major or additional diagnosis was recorded and the potential risk factors for HF were explored. Left ventricular systolic function was evaluated in HF patients by using ejection fraction (EF) measured by echocardiography. Multivariate Logistic regression analysis was used to identify the independent factors contributing to HF in medical ICU patients. Results Of the 887 patients, 74. 1％ aged 65 years or over, and 53％ had organ dysfunction. The prevalence of HF in medical ICU patients was 22. 8％. Echocardiography measurement revealed that left ventricular systolic function was preserved in 62. 5％ of HF patients with an EF ＞ 50％. Underlying heart diseases were identified in 72. 8％ of the HF patients, and coronary artery disease accounted for the vast majority (52. 5％ ), followed by valvular heart disease ( 17. 8％ ). Structural heart diseases were not identified in 27. 2％ of the HF patients. 4) After the adjustment of age and gender, multivariate regression analysis showed that coronary artery disease ( OR =7. 364, 95％ CI: 4. 979 ～ 10. 890, P ＜0. 01 ), valvular heart disease ( OR =18. 023, 95％ CI: 9. 280 ～ 35. 002, P ＜ 0. 01 ), diabetes mellitus ( OR =2. 154, 95％ CI: 1. 227 ～ 3. 784, P =0. 0076), respiratory failure ( ( OR =1. 527, 95％ CI: 1. 045 ～ 2. 229, P =0. 0285 ), and renal dysfunction ( OR =2. 638, 95％ CI: 1. 621 ～ 4. 294, P =0. 0001 ) were associated with risk increased for HF in medical ICU. ConclusionsHF is highly prevalent in medical ICU and its etiology is multi-factorial. The high rate of HF with preserved EF highlights the importance of enhanced alertness for HF with preserved systolic function in ICU.

OBJECTIVE To know the bacterial distribution in the blood of septicemia patients and the characteristics of drug resistance.METHODS To train the blood in BD BACTEC 9050 full-automatic blood training system and to analyze it in the FOUTUNE IMS bacterial identification and hypersusceptibility analysis system of Fuxing Company.RESULTS The Gram-negative bacilli were in superiority with 64.9% of the total isolated bacteria.Then were the Gram-positive cocci,and Staphylococcus were the main.The Enterococcus and fungi were with a certain proportion.The drugs to which had relatively low resistance for the Gram-positive bacilli and the Gram-positive cocci were the carbapenems,the enzyme inhibitors and vancomycin.CONCLUSIONS The Gram-negative bacilli get priority in the blood bacteria in patients with septicemia during the last two years,the enterococci and fungi have a certain proportion.And the pathogenic bacteria have higher resistance clinically to antibacterial drugs.

Our studies tried to demonstrate Eha (Et haemolysin activator) could regulate the resistance of the bacterium against acidification to survive in the macrophage and explain its underlying molecular mechanism.When the bacteria infected the macrophages at time intervals,intracellular survival rate in bafilomycin-treated macrophages was higher than that with untreated cells,and the rate of wild type ET 13 was higher than that of its eha mutant,respectively (P＜0.05).The survival rate of the wild type was higher than that of the mutant under acid treatment (P＜0.05).To determine the conditions that induced the highest eha expression,we constructed a pMP220-Peha LacZ plasmid and determined the lacZ expression under different conditions.After exposure of pH6.3 medium for 2 h time,we performed the whole transcriptomic profiles of the wild type and mutant by RNA-sequencing.We identified 147 differentially-expressed genes ([log2 ratio| ≥1),113 and 34 of which were significantly up-and down-regulated,respectively in the mutant,comparing with the wild type.These findings were validated by qRT-PCR.GO functional analysis revealed that these genes were divided into 25 categories,including the bacterial catalysis,cellular composition,combination,localization,metabolism,processing,and transportation.Based on the KEGG database,these genes were distributed in 55 pathways,such as two-component system,ABC transporters,and microbial metabolism in diverse environments.Overall,Eha is an important regulator to affect all kinds of target genes and pathways for E.tarda to adapt to an acid environment.These results could be helpful for further investigations of the mechanisms by which E.tarda survives in macrophages.

Objective To investigate the effects ofZhenqi-Fuzheng capsule combined with highly active antiretroviral therapy (HAART) the Thl/Th2, Tcl/Tc2, and CD4+ T lymphocytes in patients with advanced AIDS.Methods A total of 70 patients with advanced AIDS were randomly divided into a treatment group and a control group, with 35 patients in each group. The treatment group was treated withZhenqi-Fuzheng capsule combined with HAART, while the control group was treated with HAART only. The patients in both groups were treated for 24 weeks. The Thl, Th2, Tcl, Tc2 and CD4+ T lymphocytes in peripheral blood were detected by flow cytometer.Results After treatment, the ratios of Th1/Th2 (6.27 ± 0.70vs. 5.39 ± 0.64;P<0.05) and Tcl/Tc2 (10.70 ± 0.68vs. 10.16 ± 0.85;P<0.05) in the treatment group showed significantly higher than those in the control group. The CD4+T lymphocytes after the treatment in both groups showed significantly increased than that before the treatment (treatment group: 289.2 ± 101.5/mlvs. 121.1 ± 77.5/ml,P<0.01; control group: 231.6 ± 97.6/mlvs. 118.9 ± 76.2/ml,P<0.01). The CD4+T lymphocytes in the treatment group showed significantly increased than that in the control group after the treatment (P<0.05).ConclusionsZhenqi-Fuzhengcapsule combined with HAART may regulate the Thl/Th2 and Tcl/Tc2, and increase the CD4+ T lymphocytes in patients with advanced AIDS.

Objective To evaluate the value of HbA2 level determined by capillary electrophoresis (Hb-CE)in screening and diagnosis of thalassemia.Methods HbA2 level of 249 thalassaemia carriers and 142 healthy controls confirmed by molecular biological detection were determined by Hb-CE method.The thalassaemia carrier subjects were divided into different groups and subgroups according to their results of gene detection.The sensitivity,specificity,accuracy,positive predictive value and negative predictive value for the diagnosis ofα-thalassemia,β-thalassaemia,α,β-thalassaemia were calculated under different HbA2 cut-off value.Results Mean value of HbA2 in healthy controls was (3.03±0.27)%.Mean values of HbA2 inα-thalassemia group and its subgroups of silentα-thalassemia,standardα-thalassemia and hemoglobin H disease were (2.38± 0.55)%,(2.61±0.46)%,(2.47 ± 0.32)% and (1.07 ± 0.17)%,respectively.Mean values of HbA2 inβ-thalassaemia group and itsβ0 subgroup,β+ subgroup were (5.65±0.47)%,(5.71±0.48)% and (5.56±0.43)%.Mean value of HbA2 in compoundαandβ-thalassaemia group was (5.7±0.82)%.Compared with healthy controls,HbA2 level inα-thalassemia group,silentα-thalassemia subgroup,standardα-thalassemia subgroup and hemoglobin H disease group decreased signifi-cantly (t values of 11.73,5.02,12.91 and 33.46,respectively,P<0.01).HbA2 level in hemaglobin H disease was signifi-cantly lower than silent and standardα-thalassemia subgroups (t values of 15.62 and 21.31,respectively,P<0.01),but there were no differences in HbA2 level between silent and standardα-thalassemia subgroups (t=1.50,P>0.05).HbA2 level inβ-thalassaemia group,β0 subgroup,β+ subgroup and compoundαandβ-thalassaemia group increased significantly (t values of 55.12,44.33,38.94 and 9.10,respectively,P<0.01),but there were no differences in HbA2 level betweenβ0 andβ+ subgroups (t=1.79,P>0.05).Of 249 thalassemia carriers,all 124β-thalassaemia carriers were distinguished with ele-vated HbA2 level (>3.5%)determined by Hb-CE and only 57 were distinguished from 117α-thalassemia carriers by Hb-CE.Under the cut-off value of 2.5%,the sensitivity,specificity,positive predictive value,negative predictive value and accu-racy for the diagnosis ofα-thalassemia were 48.72%,97.18%,93.44%,69.70%,75.29%,respectively.Under the cut-off value of 3.5%,they were 100.00%,98.59%,98.41%,100%,and 99.25% for the diagnosis ofβ-thalassaemia,respectively. The analysis of ROC curve showed that the optimal HbA2 cut-off values for diagnosis ofα,β-thalassaemia by capillary elec-trophoresis were 2.8% and 3.7%,respectively.Conclusion When no abnormal bands,the elevated HbA2 (>3.7% in this study)determined by Hb-CE could be used as a marker forβ-thalassaemia diagnosis,but theβ-thalassaemia co-existingα-thalassemia could not be differentiated fromβ-thalassaemia diagnosis.Decreased HbA2 level (<1.5% in this study)and HbH band could be used for the diagnosis of hemoglobin H disease.Only HbA2 determination by Hb-CE has no clinical sig-nificance for the screen and diagnosis ofα-thalassemia.
