Sepsis may result in a high mortality.Fish oil,which riches in?-3 polyunsaturated fatty acids,has anti-inflammatory and immune regulatory functions.?-3 fatty acids,which are special immune nutrient substrates,participate in the energy provision as well as improve organ function and regulate proinflammatory/anti-inflammatory cytokines.The ideal function of fish oil is associated with dosage,time of initiation and duration of application.

ObjectiveTo explore the relationship between anastomotic leakage of patients undergoing colonic surgery and the collagen metabolism of colonic wall.Method We measured the overall collagen content of colonic tissue by biochemistry and detected the collagen I, III, MMP-1,MMP-13 by immunohistochemistry in 16 patients with anastomotic leakage compared with 16 control cases. Resultthe overall collagen content and collagen I,III of colonic wall in the leakage group were lower than those in the control group (t=3.417,t=2.841, t=2.261,P

Objective To explore the risk factors and prevention measures for anastomotic leakage after rectal radical resection.Methods The clinical data of 404 patients with rectal radical resection were analyzed retrospectively and the risk factors for anastomotic leakage were analyzed.Results Thirty-one patients (7.67％,31/404) were subjected to anastomotic leakage.The mean leakage time was 6.5 (3-14) d postoperatively.The muhivariate Logistic regression analysis showed that preoperative hemoglobin (OR =3.023,95％ CI:1.101-8.303,P=0.031 8),tumor size (OR =2.543,95％ CI:1.075-6.018,P=0.033 7) and tumor distance from anal verge (OR =3.160,95％ CI:1.387-7.199,P=0.006 2) were the risk factors for anastomotic leakage.Conclusions Preoperative hemoglobin,tumor size and tumor distance from anal verge are significant factors for anastomotic leakage.Therefore correction of anemia,improvement of surgical technique and suitable use of preventive diversion stoma ane all benefit for prevention of anastomotic leakage after rectal radical resection.

Objective To study drug resistance of carbapenem-resistant Klebsiella pneumonia ( CRKP) in neonates hospitalized in the neonatal unit , and to identify the risk factors for CRKP colonization in neonates .Methods Totally 108 neonates with Klebsiella pneumonia colonization admitted in Department of Neonates , the Second Hospital of Tianjin Medical University during January 2012 and June 2014 were enrolled in the study , including 23 cases with CRKP colonization ( case group ) and 85 cases with carbapenem-sensitive Klebsiella pneumonia (CSKP) colonization (control group).Chi-square test and fisher exact test were used to compare the differences in resistance to 21 antibiotics between CRKP and CSKP . Univariate analysis and Logistic regression analysis were performed to identify the risk factors for CRKP colonization in neonates .Results All of the CRKP strains were resistant to penicillins , cephalosporins and SMZco, and 95.7% and 87.0% of the CRKP strains were resistant to meropenem and imipenem , respectively.All of the CRKP strains were susceptible to amikacin , gentamicin, ciprofloxacin and tetracycline, but were highly resistant to the rest 16 antibiotics compared with CSKP strains (all P<0.05). Univariate analysis showed that 14 factors were associated with CRKP colonization: exposure to cefoxitin (χ2 =20.053, P<0.01), sputum suction (χ2 =15.817, P<0.01), gastrointestinal decompression (χ2 =10.731, P<0.01), nasogastric feeding (χ2 =15.146, P<0.01), invasive procedure (χ2 =22.572, P<0.01), birth weight (χ2 =6.026, P<0.05), frequency of sampling for CRKP/CSKP (χ2 =18.577, P<0.01), hypertension of pregnancy (χ2 =8.698, P<0.01), premature birth (χ2 =4.904, P<0.05), prenatal hospitalization experience (χ2 =8.396, P<0.01), adequacy for gestational age (χ2 =7.295, P<0.05), gestational age (χ2 =7.294, P<0.05), rupture of membranes (χ2 =9.397, P<0.01), length of hospitalization (χ2 =14.649, P<0.01) and admission to the neonatal intensive care unit (NICU) (OR=11.050, P<0.01).Multivariate Logistic regression analysis showed that hypertension of pregnancy (OR=9.718, P<0.01), rupture of membranes ( <24 h) (OR=6.640, P<0.01) and admission to NICU ( OR=4.119, P<0.05) were independent risk factors for CRKP colonization .Conclusions CRKP strains are highly resistant to most antibiotics .Preventing hypertension of pregnancy and rupture of membranes , and monitoring bacterial resistance in NICU may help to reduce the occurrence of CRKP colonization and dissemination .

Objective To evaluate the stability of dipstick dye immunoassay (DDIA) kit forschisitosomiasis diagnosis. Methods By means of detection of the sera from infected people withSchistosoma japonicum and healthy people, the stability of the DDIA kit, which stored at 37℃,room temperature or 4 ℃ respectively, was evaluated depending on the detective results ofsensitivity, specificity, detectable minimum and coefficient variation ( CV). Results Thesensitivity, specificity, detectable minimum and coefficient variation of the DDIA kit were invariableafter the kits stored at 37 ℃ for 180 days, and at room temperature or 4 ℃ for 360 days.Conclusion The DDIA kit is stable while it stores at 37℃ for 180 days, and at room temperatureor 4℃ for 360 days at least.

Objective To evaluate the anti-tumour effect of 60℃ LipiodoI in the embolization of VX_2 hepatocarcinoma in rabbits.Methods VX_2 carcinoma cells were surgically implanted into the left liver lobe in 30 male New Zealand white rabbits,which were randomly divided into 3 groups by figure and table method with 10 rabbits in each group.Physiological saline,Lipiodol(37℃),and Lipiodol(60℃)were injected in each group via hepatic artery and liver cancer was embolized.The volume of tumour and serum level of aspartate aminotransferase(AST)were observed after one week,and the survival period of VX_2 rabbits was also observed.Results In the group of Lipiodol(60℃),the growth rate of tumour(0.92? 0.21)was significantly lower than that of control group(3.48?1.17)and Lipiodol(37℃)groups (1.69?0.26),respectively(F=34.95,P0.05),but was significantly higher than the control group(68.6?6.6)U/L(t=19.24,P

Objective To explore the effects of knocking down ULF gene on the apoptosis of non-small-cell carcinoma H1299 cell after treatment with etoposide.Methods Three ULF small interfering RNA(siRNA)sequences and one negative control siRNA sequence were designed and synthesized, and then individually transfected into H1299 cell via lentivirus.The interference efficiency of ULF-siRNA were screened by real-time PCR and Western blotting.Then the most target siRNA was used for apoptosis assay after treatment with etoposide,MTT assay for H1299 cell proliferation,flow cytometry for cell cycle distribution. Results The expression of ULF gene and its protein ULF were down-regulated in H1299 cell when transfected with ULF-siRNA,and ULF-siRNA-1 was the most effective one,which had the highest inhibition rate(80%)of ULF expression.Compared with negative control group,ULF-siRNA group showed an obvious apoptosis after treatment with etoposide,and the inhibition rate of was higher than control group,which was positively correlated with etoposide dose,the difference was statistically significant(P<0.05 ).Flow cytometry showed that compared with the control group,G0/G1 cell cycle in ULF-siRNA group was increased,and S phase cells was decreased,the differences were all statistically significant(P<0.05).Conclusion Down-regulation ULF protein expression through treatment with etoposide can induce apoptosis of non-small-cell carcinoma H1299 cells,and inhibit cell proliferation,which lead to cell cycle arrest.ULF gene may become the new target of gene therapy for cancer.
