Objective To explore the effects of fat emulsion made of fish oil for total parenteml nutrition on patients with systemic inflammatory response syndrome(SIRS).Methos Forty patients with SIRS in the intensive care unit(ICU),Liaocheng People's Hospital,from January to June 2007 were randomly divided into conventional total parenteral nutrition(TPN)group(group A,n=20)and fish oil emulsion+TIN group(group B,n=20).Patients of both groups received equal amount of nitrogen and calories.The energy give.Was 20 kcal/(kg·d),and nitrogen 0.2 g/(kg·d)for 7 days and the fish oil emulsion given was 1-2 ml/(kg·d)(Commoditieds:Omegaven,No.UK 1580,Wuxi,China SINO-SWEO Pharmaceutical CORP.Ltd.).The levels of serurn TNF-α,IL-1 and IL-6 were checked before TPN and 1 d,3 d and 7 d after TPN.The davs of ICU stay,the incidence of MODS and the mortality within 28 aays of two groups were also recorded.Data were analyzed wotj inde pent-saraples t test and paired-sarnples t test using the SPSS 10.34 software.Results There wsa no significant difference in APACHF-Ⅱ score between two groups of patients.Compared with group A,the levels of serum TNF-α,IL-1 and IL-6 in group B decreased markedly at different intervals(P<0.05,P<0.01).The duration of ICU slay shortened obviously in group B than that in group A[(11.5±2.4)days vs.(15.8±2.3)days,P<0.05].Conclusions The fat emulsion made of fish oil has protective effects on patients with SIRS by the mechanism of decrease in the levek of Serum TNF-α,IL-1 and IL-6,and thereby reduees the incidence of MODS,shortens the duration of ICU stay,increasing the survival rote of seriously ill patients.

The data on nosocomial infection of 4060 patients who were stayed in intensive care unit (ICU) more than 48 h from January 1997 to August 2008 were reviewed.From Jan 2004 the target monitoring of hospital-acquired infection was implemented in ICU.The nosocomial infection rates before and after target monitoring were 35.25% (871/2471) and 30.77% (489/1589) respectively (P ＜ 0.01);however there was no significant difference in case infection rate before and after target monitor were practiced (47.67% vs.45.25%,χ~2 = 2.2836,P ＞0.05).The incidence of Acinetobacter infection was increased after target monitoring.Targeted monitoring can decrease the nosocomial infection rate in ICU,and also reduce the cost of medical care.

Objective To observe the features of the changes in the whole blood N-terminal pro-brain natriuretic peptide (NT-proBNP) levels in pregnant patients with complication of hypertensive disorders,its correlation to the severity of the illness,and to investigate the diagnostic value of point-of-care testing of NT-proBNP in patients with hypertensive disorders complicating pregnancy.Methods A prospective observation was conducted.Sixty-nine patients with hypertensive disorders complicating pregnancy admitted to Department of Critical Care Medicine of Liaocheng People's Hospital in Shandong Province from April 2013 to April 2015 were enrolled.All patients were divided into gestational hypertension group (n =16),preeclampsia group (n =30) and eclampsia group (n =23).At the same time,30 age-matched normal pregnant women were enrolled as the control group.The acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) score of all patients with hypertensive disorders complicating pregnancy were calculated within 24 hours after intensive care unit (ICU) admission.NT-proBNP in venous blood at 1,3,5 days after ICU admission was determined with point-of-care testing,in order to analyze the correlation of changes in NT-proBNP value in each group and the severity of the disorder.Receiver operating characteristic (ROC) curve was plotted to evaluate the diagnostic value of NT-proBNP in the whole blood in hypertensive disorder complicating pregnancy.Results The APACHE Ⅱ score of the eclampsia group was significantly higher than that of the preeclampsia group,and it was higher than that of gestational hypertension group (15.91 ± 1.06,13.73 ± 1.09,10.31 ± 1.10,all P ＜ 0.01).The NT-proBNP in normal pregnancy group was lower than 125.00 ng/L,with a mean of 90.00 (79.75,100.00) ng/L.With the aggravation of the disease,NT-proBNP was gradually increased.On the first day in ICU,the NT-proBNP of the eclampsia gronp was significantly higher than that of the preeclampsia group,and it was higher in preeclampsia group than that of gestational hypertension group [ng/L:1960.00 (1 226.00,3 229.00),859.50 (626.75,2439.00),505.00 (171.25,604.05),P ＜ 0.05 or P ＜ 0.01].With the extension of duration of treatment,the levels of NT-proBNP (ng/L) in the eclampsia group,preeclampsia group,and gestational hypertension group was gradually decreased,and had a statistically significant difference on the fifth day as compared with that of the first day [310.00 (210.00,430.00) vs.1 960.00 (1 226.00,3 229.00) in eclampsia group,265.00 (229.50,333.25) vs.859.50 (626.75,2439.00) in preeclampsia group,and 203.00 (115.50,259.25) vs.505.00 (171.25,604.05) in gestational hypertension group,all P ＜ 0.01].APACHE Ⅱ score of the patient with hypertensive disorders complicating pregnancy was positively correlated with the level of NT-proBNP on the first day in ICU (r =0.795,P =0.000).It was shown by ROC curve analysis that the area under the ROC curve (AUC) of NT-proBNP in the whole blood for the diagnosis of the patient with hypertensive disorder complicating pregnancy was 0.986 [95％ confidence interval (95％C/) =0.753-0.924].When the cutoff value was 122.50 ng/L,the sensitivity was 97.1％,and the specificity was 100.0％.No patient died,all the 69 patients recovered and discharged.Conclusions The levels of NT-proBNP in the whole blood in the patients with hypertensive disorder complicating pregnancy,especially those with eclampsia,were significantly higher,and it was correlated with the severity of illness.After treatment,the levels were gradually lowered with the improvement of the disease.Therefore,it is concluded that the point-of-care testing of NT-proBNP in the whole blood has an excellent value for the diagnosis and evaluation of hypertensive disorder complication pregnancy.

Object To investigate the preparation technique and optimal formulation of Breviscapin Sustained release Pellets (BSP) and the release mechanism of breviscapin from the pellets. Methods BSP was prepared by extrusion spheronization method. Based on the studies of influential factors, optimal formulation modified to release drug over 12 h was obtained by the orthogonal design. And release mechanism of breviscapin from BSP was established by equation fitting. Results Prepared BSP has such advantages as simple technique, uniformity in diameters and high loading with even contents. They can release drug for 12 h. And the release of breviscapin could be mainly controlled by diffusion associated with slight erosion. Conclusion Extrusion spheronization method is simple for the preparation of BSP, and useful for the large scale prodution.

Objective To investigate the diagnostic values of procalcitonin (PCT),high sensitive C-reactive protein (hs-CRP),white blood cell (WBC)and percentage of neutrocyte (NEU％)in Gramnegative and Gram-positive bacterial blood stream infection in early stage of sepsis in order to investigate the correlation between PCT and APACHE lⅡ score as well as between PCT and SOFA score,and the prognostic value in assessment of Gram-negative and Gram-positive bacterial blood stream infection.Methods Clinical data of patients admitted to ICU from January 2012 through December 2014 were retrospectively analyzed.A total of 124 sepsis patients with blood stream infection were checked with PCT,hs-CRP,WBC and NEU％ tests,and APACHE Ⅱ score and SOFA score were calculated.The differences in APACHE Ⅱ score and SOFA score were compared between Gram-negative group (n =41) and Gram-positive group (n =83).The correlation between PCT and APACHE Ⅱ score as well as between PCT and SOFA score was analyzed.The differences in diagnostic values of PCT,hs-CRP,WBC and NEU％ between Gram-negative group and Grampositive group were analyzed by using receiver operating characteristic (ROC) curve and it was plotted to assess the prognostic values of PCT,hs-CRP,WBC and NEU％ for septic patients with blood stream infection.Results Compared with Gram-positive group,the levels of PCT [.55.32 (22.01,97.11) vs.2.13 (0.27,5.27)] (P ＜0.01),hs-CRP [105.09 (69.97,186.12) vs.70.54 (42.37,138.63)] (P=0.508),NEU％ [88.30 (75.79,93.52) vs.55.32 (22.01,97.11)] (P=0.302) were higher but WBC was lower [13.59 (10.74,17.58) vs.13.73 (11.32,20.90)] (P=0.058) in Gram-negative group.The ROC curve analysis of PCT showed the area under the curve (AUC) was 0.867 (95％ CI:0.789-0.946).When the optimal cutoff point of PCT was 17.48 ng/mL,the largest Youden's index was found to be 0.661 with 76.9％ sensitivity and 89.2％ specificity.Between two groups,there were significant differences in APACHE Ⅱ score and SOFA score (27.46 ± 9.60 vs.23.67 ± 7.74,P =0.020;8.05 ±3.38 vs.6.59-±3.45,P =0.028).There was significant difference in diagnostic value between PCT and SOFA (r =0.536,P =0.036) in Gram-negative group but no significant difference in Gram-positive group.Conclusions Higher PCT levels are found in Gram-negative group and it can play a role in differntiation between the Gram-negative group and Gram-positive group rather than hs-CRP,WBC and NEU％.PCT can be a better indicator for evaluation of severity of sepsis as well as for prognosis of sepsis patients with Gram-negative bacterium infection.

Objective:To investigate the association between glutathione S-transferase pi (GSTP1) gene polymorphism and toxici-ties related to high-dose methotrexate (HD-MTX) in children with acute lymphoblastic leukemia (ALL). Methods:GSTP1 genotypes and allelic frequencies in 51 children with ALL were determined by Nest PCR, denaturing gel gradient electrophoresis (DGGE), and DNA sequencing. HD-MTX adverse reactions were analyzed using the National Cancer Institute Common Toxicity Criteria (NCICTC). Results:We identified three SNPs of GSTP1, including rs1695 (A313G), rs1138272 (G439T), and rs4891 (T555C). The wild types, het-erozygous types, and homozygous types of GSTP1 rs1695/rs4891 polymorphisms were detected in 32 cases (62.7%), 16 cases (31.4%), and 3 cases (5.9%), respectively. GSTP1 rs1695/rs4891 polymorphisms included only one heterozygous type and one homozygous type. The allele frequencies of the three SNPs were 21.6%, 2.9%, and 21.6%. The AG+GG/TC+CC genotype of GSTP1 rs1695/rs4891 was associated with decrease in the odds of peripheral hemoglobin (OR=0.25, 95%CI=0.06-1.00, P=0.049). The AG+GG/TC+CC genotype of GSTP1 rs1695/rs4891 in standard and intermediate-risk ALL children was significantly correlated with higher odds of gastrointesti-nal toxicity (OR=0.125, 95%CI=0.02-0.78, P=0.026). Conclusion:GSTP1 rs1695 (A313G)/rs4891 (T555C) gene polymorphism is as-sociated with the reduction of peripheral hemoglobin in ALL children and with the odds of gastrointestinal toxicity in standard and inter-mediate-risk ALL children who receive high-dose methotrexate.

OBJECTIVE Through nosocomial infection targeted surveillance in intensive care unit(ICU),to evaluate the characteristics of nosocomical infection and their its correlation with the results of environmental monitoring at the same period.METHODS Nosocomial infection monitoring was explored on patients who were in ICU more than 48 h from Jan 1997 to Jun 2008.Correlation analysis was conducted between the rate of nosocomial infection in ICU and the same period environmental monitoring results.Data were analyzed with the SPSS10.34 software.RESULTS There was significant difference(P0.05)in the rate of infection cases before and after target monitoring was practiced.The site of infection was mainly in respiratory tract,followed by the gastrointestinal tract and urinary tract;The full-time personnel in duty for nosocomial infection surveillance monitored the indoor air,object surface,medical personnel's hands in ICU,their qualified rate was 78.28%,90.94% and 95.83%,respectively.CONCLUSIONS There are many risk factors in patients in ICU,ICU should be looked as one of the important nosocomial infection monitoring department.The target monitoring of nosocomial infection is an effective method;the nosocomial infection rate in ICU and the environmental result at the same period don't show relevance,the environmental hygiene monitoring should be scientific and practical.

Objective To investigate the brain perfusion changes in patients with refractory depressive disorder (RDD) and non-refractory depressive disorder (NDD) using arterial spin labeling (ASL).Methods Present study included 12 patients with RDD, 37 patients with NDD and 42 controls,and their age, sex and handedness were matched among the three groups.FAIR sequences were performed using a 3 T MR imaging system with an 8 channel phase array head coiL The labelled and controled images were subtracted and then averaged to obtain perfusion-weighted images.The first 2 images were excluded to avoid T, equilibrium effects and then voxel based analysis was performed using SPM2. One way ANOVA analysis using age as covariance ( thresholded at P ＜ 0.01 uncorrected) was performed.Results Patients with NDD showed regional alteration of the brain perfusion, mainly involved in two frontal subcortical circuits, i.e. significantly decreased perfusion in the left frontal and thalamus (the limbic thalamo-cortical circuit) whereas significantly increased perfusion in bilateral hippocampi, fight lentiform and left anterior cingulated gyros (the limbic-striatal-pallidal-thalamic circuit).In contrast, patients with RDD presented significantly decreased perfusion involving bilateral frontal areas (the limbic-thalamo-cortieal circuit) whereby no significantly increased perfusion areas were observed.Conclusion In addition to the reported experimental evidences, our results suggest that the RDD is associated with inactivity of bilateral frontal areas, while the NDD is associated with inactivity of left frontal areas and overactivity of bilateral limbic system.

Objective To investigate distribution and antimicrobial resistance among nosocomial pathogens from 13 teaching hospitals in China in 2009. Methods Non-repetitive pathogens from nosocomial BSI, HAP and IAI were collected and sent to the central lab for MIC determination by agar dilution method.WHONET5.6 software was used to analyze the data. Results A total of 2 502 clinical isolates were collected. The top three pathogens of BSI were Escherichia coli [27. 1% (285/1 052 )] , coagulase-negutive staphylococcus [12. 6% ( 133/1 052)] and Klebsiella pneumoniae [10. 8% ( 114/1 052)]. The top three pathogens of HAP were Acinetobacter baumannii [28. 8% (226/785)], Pseudomonas aeruginosa [16. 1% (126/785)] and Klebsiella pneumoniae [14.6% (115/785 )] . The top three pathogens of IAI were Escherichia coli[31.0% ( 206/665 )], Klebsiella pneumonia [11.3% ( 75/665 )] and Enterococcus faecium [10. 8% (72/665)]. Against Escherichia coil and Klebsiella spp. , the antimicrobial agents with higher than 80% susceptibility rate included imipenem and meropenem (98. 1%-100% ), tigecycline (95.3%-100% ), piperacillin-tazobactam ( 88.6% -97. 1% ) and amikacin ( 88. 3% -92. 5% ). Against Enterobacter spp. , Citrobacter spp. and Serratia spp. , the susceptibility rates of tigecycline were 93.5% -100% whereas the value of imipenem and meropenem were 92.9% -100%. Other antimicrobial agents with high activity included amikacin ( 85.2% -96. 7% ), pipcracillin-tazobactam ( 82.4% -96.4% ), cefepime ( 79. 6% -96. 7% ) and cefoperazonc-sulbactam (78. 7%-90. 0% ). Polymyxin B showed the highest susceptibility rateagainst Pseudomonas aeruginosa ( 100% ), followed by amikacin ( 81.9% ) and piperacillin-tazobactam (80.1% ). Polymyxin B also showed the highest susceptibility rate against Acinetobacter baumannii (98. 8% ), followed by tigecycline (90. 1% ) and minocycline (72. 0% ). The incidence of carbapenemresistant Acinetobacter baumannii was 60. 1%. The MRSA rate was 60. 2% and the MRSCoN rate was 84. 2%. All Staphylococcus strains were susceptible to tigecycline, vancomycin, teicoplanin and linezolid except for one isolate of Staphylococcus haemolysis with intermediate to teicoplanin. Two Enterococcus faecalis isolates which were intermediate to linezolid and one Enterococcus faecium isolate which was resistant to vancomycin and teicoplanin was found in this surveillance, while the MICs of tigecycline against these three isolates were 0. 032-0. 064 μg/ml. Conclusions Tigecycline, carbapenems, piperacillin-tazobactam,amikacin and cefepime remain relatively high activity against nosocomial Enterobacteriaceae. Pseudomonas aeruginosa exhibite high susceptibility to polymyxin B, while Acinetobacter baumanni shows high susceptibility to polymyxin B and tigecycline. Tigecycline, vancomycin, teicoplanin and linezolid remain high activity against nosocomial gram-positive cocci.

Brain atlas provides a spatial reference system on which other images can be interpreted in a consistent way, and it is essential for the brain imaging research. However, because of the differences in structure between occidental and oriental brains, the brain atlas based on Western populations, e. g., the International Consortium for Brain Mapping's 154 T1 Weighted Average Atlas, may not be appropriate for other ethnic groups. Therefore, in the present study, we produce an average brain atlas which is based on the data collected from 100 healthy Chinese volunteers. The differences in brains between the Chinese population and the Western population were also investigated. Comparatively,Chinese brains are wider and shorter in size, and smaller in volume.
