Objective To explore the effect of?-3 fish oil fat emulsion on the release of pro-inflam- matory cytokines in patients with systemic inflammatory response syndrome(SIRS).Methods Forty patients with SIRS in the intensive care unit(ICU)from June 2006 to June 2007 were randomly divided into routine total parenteral nutrition(TPN)group(group A,20 cases)and?-3 fish oil fat emulsion+TPN treatment group(group B,20 cases).All the patients received treatment of parenteral nutrition with equal nitrogen content and calories.The caloric value given was 83.68 kJ?kg~(-1)?d~(-1),with 0.2 g?kg~(-1)?d~(-1)of nitrogen. Group A patients received routine TPN,and group B patients received TPN with?-3 fish oil fat emulsion 1-2 ml?kg~(-1)?d~(-1),and both regimes lasted for 7 days.The levels of serum tumor necrosis factor-?(TNF-?),interleukin-1(IL-1)and IL-6 were checked before the treatment,and on the 1st,3rd and 7th day after the beginning of the treatment.The duration in ICU,the incidence of multiple organ dysfunction syndrome(MODS)and the mortality rates in 28 days of the two groups were also assessed.Results Compared with the routine treatment group,the levels of serum TNF-?,IL-1,and IL-6 in the?-3 fish oil fat emulsion+TPN treatment group were lower markedly(P0.05).Conclusion The emulsion of?-3 fish oil fat seems to have a protective effect on patients with SIRS through decreasing the levels of serum TNF-?,IL-1 and IL-6,thus reducing the incidence of MODS,shortening the ICU stay, and increasing the survival rate of serious patients.

Background and purpose:Vascular endothelial growth factor(VEGF) is a potent angiogenic mediator and angiogenesis has important effects on tumor growth and metastasis.The present study was to investigate the relationship between genetic polymorphism of VEGF and heredity risk factor of lung cancer.Methods:VEGF genotypes were determined by PCR-RFLP method in 171 patients with lung cancer and 172 healthy controls.Software PHASE 1.0 was used to construct the haplotypes of every individual.Unconditional logistic regression model was used to analyze the statistical association of genotypes or haplotypes in the two groups adjusted by gender and age. Results:Individuals with at least one-2578A allele had a significantly decreased risk of lung cancer compared with those carrying-2578CC genotype.When the analyses were stratified by gender,the combined-2578 CA and AA genotype,were associated with a considerably reduced risk of lung cancer(P=0.001,OR=0.303,95%CI=0.15 3-0.601).The distribution of the two haplotypes(936C/-2578C and 936C/-2578A) among overall lung cancer cases was significantly different from that among the controls(P=0.016,0R=0.317,95%CI=0.124-0.809 and P=0.018,OR=0.547, 95%CI=0.331-0.903).When the cases were categorized by tumor histology,the distribution of C-C haplotype in the adenocarcinoma(AC) group was associated with a substantially lowered risk of AC(P=0.004,0R=0.237,95%CI=0.090- 0.627),compared with the reference haplotypes.Conclusion:VEGF polymorphism may be a critical risk for the genetic risk factor to lung cancer.

OBJECTIVETo explore the morbidity, burdens caused and risk factors of injuries among children and to provide information for policy making on prevention.

METHODSBy PPS sampling method, we selected 28 000 households in Beijing and using a questionnaire developed by UNICEF, TASC and China CDC.

RESULTSThe morbidity of child injury in Beijing was 2.25%, higher than that of adults (1.56%) with 6-9 year group the highest (2.83% ). The morbidity of boys was 3.04% higher than that of girls (1.37%). Among the 7 death cases, 3 were caused by injury(2 RTA, 1 drowning). The three leading causes of injuries were fall, animal bite and road traffic accident in children. Among children aged 0-5 years, fall, animal and burn/machine injuries were the leading causes. Among children aged 0-5 years, the leading causes were hurt by animals, fall and RTA with the leading causes as fall, sprain and RTA. The average medical cost of injury cases was 1617.57 Yuan. There were 3500 children (injured orphan) whose parents were injured leading to death or disability in Beijing in 2003.

CONCLUSIONInjury was the leading cause of child deaths in Beijing with children of 6-9 years old having the highest morbidity with RTA the most severe type of injuries in Beijing which affects both children and their parents.

BACKGROUNDEncephalopathy is a common complication of sepsis, and its onset can occur at any stage of sepsis and implies worse prognosis. However, the incidence, epidemiology, and pathogenesis of sepsis-associated encephalopathy remain controversial. The purpose of this study was to investigate the epidemiological features and risk factors for sepsis-associated encephalopathy.

METHODSOur retrospective study included all patients with sepsis admitted to our intensive care unit from 2008 to 2011. After excluding 91 patients, 232 patients were assigned to either a sepsis-associated encephalopathy group or sepsis without encephalopathy group. Between-group differences in baseline patient data including vital signs, disease severity, pathogens, sites of infection, biochemical indicators, and time on a mechanical ventilator, intensive care unit (ICU) stay, and 28-day mortality rate were analyzed.

RESULTSThe incidence of sepsis-associated encephalopathy was 17.7%. The sepsis-associated encephalopathy group had significantly higher 28-day mortality (56.1% vs. 35.1%; P=0.013), spent a significantly longer time on a ventilator ((8.2±2.2) days vs. (2.9±0.4) days; P=0.021), and had a significantly longer ICU stay ((12.4±2.4) days vs. (7.1±0.6) days; P=0.042). Acute physiology and chronic health evaluation II score, Glasgow coma scale, heart rate, blood lactate, serum sodium, platelets, serum albumin, and pH values were related to the presence of encephalopathy. Patients with biliary tract infections and intestinal infections caused by Staphylococcus aureus, Enterococcus faecium, Acinetobacter spp, Pseudomonas aeruginosa, and Stenotrophomonas maltophilia, were more prone to develop sepsis-associated encephalopathy.

CONCLUSIONSEncephalopathy increases mortality rate in septic patients. Clinical intervention to reduce risk factors and thereby morbidity and mortality depends on a correct understanding of the differences between patients with sepsis and patients with both sepsis and encephalopathy.

OBJECTIVETo study the regulatory effect of galectin-9 isoforms on some molecules involved in cell adhesion/invasion, and the influence of this regulation action on the adhesion between colon carcinoma LoVo cells and human umbilical vein endothelial cells (HUVECs) in vitro.

METHODSVarious expression vectors of galectin-9 isoforms were transfected into LoVo cells. 24 h after transfection, the expression of integrin-beta1, E-cadherin, E-selectin, ICAM-1, CD44 and MMP-9 was detected by RT-PCR and Western blot analysis. LoVo cell-HUVEC adhesion assay was performed under conditions of galectin-9 transfection, galectin-9 transfection + galectin-9 antibody, galectin-9 transfection + E-selectin antibody and galectin-9 transfection + beta-lactose, respectively.

RESULTSGalectin-9L down-regulates the mRNA and protein levels of E-selectin while galectin-9M and galectin-9S up-regulate the expression of E-selectin. In LoVo cell-HUVEC adhesion assay, the average fluorescence intensity of vector transfection group, galectin-9L transfection group, galectin-9M transfection group and galectin-9S transfection group was 0.90 +/- 0.20, 0.94 +/- 0.24, 1.60 +/- 0.11 and 1.45 +/- 0.13, respectively, indicating that galectin-9M and galectin-9S facilitated the adherence of LoVo cells to HUVECs (P < 0.05). E-selectin antibody, galectin-9 antibody or beta-lactose inhibited that effect.

CONCLUSIONGalectin-9 isoforms regulate the E-selectin expression in LoVo cells differently and thus influence the adhesion between LoVo cells and HUVECs in vitro in different modes. The mechanisms through which galectin-9 isoforms participate in the metastasis process of colon cancer may not be the same.

The aim of study is to explore the characteristics of cytogenetics and molecular biology in patients with eosinophilia. Bone marrow samples from 79 cases of eosinophilia (AEoC ≥ 1.5×10(9)/L) were detected for PDGFRA/B and FGFR1 gene rearrangement by fluorescence in situ hybridization and reverse transcription polymerase chain reaction (RT-PCR). Forty-four samples were detected for T cell receptor (TCR) clonal rearrangement by PCR. The results showed that among 76 cases the FIP1L1/PDGFRA (F/P) fusion gene was detected in 19 cases, the CHIC2 deletion was detected in 19 cases, the PDGFRA rearrangement was detected in 4 cases, and no FIP1L1 rearrangement was detected. According to the 2008 WHO classification, diagnosis were revised as myeloid neoplasms with PDGFRA/B rearrangement in 20 (42%) of 48 patients and 5 (83%) of 6 patients with hypereosinophilia syndrome (HES) or chronic eosinophilic leukemia (CEL), respectively. The diagnosis in (17%) of 6 patients with CEL was revised as chronic eosinophilic leukemia, not otherwise as specified (CEL-NOS). Clonal cytogenetic abnormalities were detected in 1 case of CEL-NOS and 3 cases with PDGFRB rearrangement. Karyotypic abnormalities involved in chromosome 4q12 were not detected in all of the 21 cases with PDGFRA rearrangement. The clonal TCR gene rearrangement were detected in 33% (5/15), 40% (6/15), and 36% (5/14) cases with PDGFRA/B rearrangement, HES, or secondary eosinophilia, respectively. There was no statistical difference in incidence rate among 3 subgroups. It is concluded that PDGFRA/B rearrangement can be detected in many cases of HES or CEL. Interphase FISH and PCR testing can enhance the diagnostic rate of myeloid neoplasms with PDGFRA/B rearrangement.

BACKGROUNDReliable early prediction response to therapy and time-to-progression (TTP) remain an important goal of high-grade gliomas (HGGs) research. Proton magnetic resonance spectroscopy ((1)H-MRS) has been applied with variable success in clinical application, and we hypothesize that (1)H-MRS in predictive value should perform well as a marker of TTP in patients treated with radiotherapy (RT) after surgery.

METHODS(1)H-MRS was performed before surgery on 25 patients who had undergone resection of HGGs; then the ratios of lipid/creatine (Lip/Cr) and myo-inositol/creatine (mI/Cr) were determined in the solid tumor. RT response was classified as follows: complete resolution (CR), partial response (PR), stable disease (SD), and progressive disease (PD) by comparison of pre-treatment and post-radiotherapy scans. TTP was defined at the time to radiographic progression by MacDonald criteria. Correlation was evaluated between the ratios of Lip/Cr, mI/Cr and treatment response, TTP. The chi-square test and Pearson correlation test were used for data analyses.

RESULTSMultivariate analysis revealed that the prognostic value of spectroscopic variables was independent of age, sex, WHO histologic grade, extent of surgery, and Karnofsky score (KPS). The correlation between the ratios of lipid/Cr and TTP was significant (r = 0.894, P = 0.000), and between the ratios of mI/Cr and TTP was also significant (r = 0.891, P = 0.000). As predicted, RT response correlated significantly with TTP (r = 0.59, P = 0.002): median TTP was 49.9 days for patients with PD compared with 202.7 days for SD, 208.0 days for PR, and 234.5 days for CR.

CONCLUSIONThe ratios of Lip/Cr and mI/Cr of the solid tumor region before surgery could provide important information in predicting RT response and TTP in patients with HGGs treated by radiation alone after surgery.

OBJECTIVETo establish the norms of Sub-Health Measurement Scale Version1.0 (SHMS V1.0) for Chinese civil servants.

METHODSWe sampled a total of 15 000 civil servants form Tianjin (north China), Guangdong (south China), Anhui and Hunan (central China), Xinjiang (northwest China) and Shenyang (northeast China) to perform the spot trial, and established the mean, percentile and threshold norms based on the characteristics of SHMS V1.0 scores for Chinese civil servants.

RESULTSThe established norms based on the average scores of SHMS V1.0 showed a mean score of 66.55∓12.36 for young male subjects (below 40 years), 67.42∓12.40 for older male subjects, 66.22∓11.81 for female subjects younger than 40 years, and 65.94∓11.91 for older female subjects. The threshold norms of SHMS V1.0 divided 5 health states, namely disease, severe sub-health, moderate sub-health, mild sub-health and healthy states according to the Mean∓SD and Mean∓0.5SD of the converted scores. The 4 cut-off points were close to the 15th, 30th, 70th and 85th percentile scores of SHMS V1.0.

CONCLUSIONWe have established SHMS V1.0 norms for Chinese civil servants, which facilitates further investigation of the incidence of sub-health state and its contributing factors in civil servants.
