Objective:To observe the influence of the CD96 and CD71 expressions in the surface of leukemia stem cells (LSC) in the therapeutic effects and prognosis of the children with acute leukemia,and to clarify the relationships between the molecular biological characteristics of LSC in the children with leukemia and their therapeutic effects and prognosis.Methods:Eighty children with acute leukemia were selected as the subjects.Among them, 39 cases were acute lymphoblastic leukemia (ALL) and 41 cases were acute myeloid leukemia (AML).The CD96 and CD71 expressions on the surface of LSC were detected with flow cytometry;the therapeutic effects of the first cycle chemotherapy, the survival rate of 5-year, the incidence of infection after chemotherapy, the recurrence rate after chemotherapy, and the incidence of extramedullary infiltration of the children were observed and compared.Results: The CD96 expression on the surface of LSC was positive in 38 cases (47.5%) and the CD71 expression on the surface of LSC was positive in 45 cases (56.3%);the difference of positive expression rates of CD96 and CD71 was not significant (χ2=1.227, P=0.268).The positive expression rates of CD96 and CD71 on the surface of LSC of the children with AML were significantly higher than those in the children with ALL, and the differences were statistically significant (χ2=22.225, χ2=34.028, P<0.01).The distribution of therapeutic effects and the clinical efficiency of the first cycle chemotherap, in the children with negative CD96 expression on the surface of LSC were superior to those with positive CD96 expression on the surface of LSC;the distribution of therapeutic effects and the clinical efficiency of the first cycle chemotherapy in the children with negative CD71 expression on the surface of LSC were superior than those with positive CD71 expression on the surface of LSC;the differences between two groups were statistically significant (χ2=11.323, χ2=16.589, P<0.05;U=2.939, U=2.291, P<0.05).The survival rate of 5-year in the children with negative CD96 expression on the surface of LSC was higher than those with positive CD96 expression;the incidence of infection after chemotherapy,the recurrence rate after chemotherapy and the incidence of extramedullary infiltration were lower than those with positive CD96 expression.The incidence of infection after chemotherapy and the recurrence rate after chemotherapy in the children with negative CD71 expression on the surface of LSC were lower than those with positive CD71 expression,and the differences between two groups were statistically significant (χ2=5.051,χ2=13.288, P<0.05).Conclusion: The expressions of CD96 and CD71 on the surface of LSC in the children with acute leukemia has relationship with the subtypes of the disease and the therapeutic effects of the first cycle chemotherapy, which can be used as markers for the diagnosis and evaluation of therapeutic effects.The expression level of CD96 is related to the prognosis of the patients, which can be used as an indicator for predicting the prognosis of patients.

Antiradiation drugs, also known as radioprotective agents, can prevent humans from radiation injury,reduce the clinical symptoms of radiation sickness,promote early recovery and reduce morbidity or mortality.Early developments of such agents focused on thiol synthetic compounds, such as amifostine (WR 2721).This compound reduced mortality, but its disadvantages, such as large use and high toxicity, limited its use in clinical practice.To find a suitable radioprotective agent is crucial to reducing side effects induced by ionizing radiation and increasing survival rate in patients during radiotherapy.In this paper, the classification and mechanism of radioprotective agents are reviewed and future developments in this field are predicted.

Objective To explore the significances of expression of tumor associated macrophages ( TAMs) and its correlation with microvessel density ( MVD) in triple negative breast cancer ( TNBC) .Methods Immunohistochemistry was used to detect TAMs and MVD expression in 108 TNBC tissues and to analyze the cor-relation between TAMs with clinicopathological features ,prognosis and MVD.Results The expression of TAMs was correlated with the tumor size,lymph node metastasis,histological grade,TNM stage and MVD,but had no statistically significant association with age .TAMs was correlated with 5 year disease free survival ( DFS) and over-all survival( OS);MVD was correlated with 5 year DFS, while no correlation with OS .Univariate and multivariate analyses showed that TAMs was an independent unfavorable prognostic factor for patients with TNBC .Conclusion High infiltration of TAMs indicated poor survival rate for patients with TNBC .The infiltration of TAMs was a new,important risk factor for TNBC recurrence .TAMs were closely related to MVD ,by promoting tumor angiogen-esis,thereby promoting TNBC growth ,invasion and metastasis ,and further affect the prognosis of patients with TN-BC.

A high performance liquid chromatography-tandem mass spectrometric( HPLC-MS/MS) method was developed for the simultaneous determination of four phenolic and salicylanilide anthelmintics including nitroxinil, oxyclozanide, closantel and rafoxanide in cattle and ovine tissues. Muscle, liverand kidney were extracted with acetonitrile-acetone(60:40, V/V)and fat with 1% triethylamine in acetonitrile, then the extract was purified with MAX solid-phase extraction column. Qualitative and quantitative analysiswas achieved by HPLC-MS/MS undernegative multiple reaction monitoring ( MRM) mode. Good correlation coefficients were obtained (R>0. 99) in the concentration range of 1-100 μg/L. The limits of detection (LOD) and limits of qualification (LOQ) for the four compounds were 1 and 2. 5 μg/kg, respectively. The mean recoveries at the four levels of LOQ, 0. 5 maximum residue limit (MRL), MRL, 2MRL were between 71% and 112%,with the intra-day relative standard deviation(RSD)in the range of 1. 1%-14. 0%and inter-day RSD in the range of 6. 4%-14. 7%. Forty samples from the market were analyzed with the method, only two samples were found to show phenolic and salicylanilide anthelmintics residues.

Objective To evaluate the nutritional status of extremely low birth weight (ELBW) infants and the effects of nutritional support strategy alterations on their growth during hospitalization.Method From 2005 to 2014,clinical data of ELBW infants admitted to the neonatal intensive care unit (NICU) in our hospital were retrospectively analyzed.The clinical data included their general status,enteral and parental nutritional support strategy and complications during hospitalization The patients were assigned into pre5 group and late5 group.Those who survived and discharged from 2005 to 2009 were the pre5 group,and those who survived and discharged fromn 2010 to 2014 were the late5 group.The independent t test and chi square test were used for statistical analysis.Result A total of 58 ELBW infants were enrolled in the study,including 18 patients in the pre5 group and 40 in the late5 group.No statistically significant differences existed between the two groups on gestational age,birth weight,Z score (weight for length and gender),birth length,head circumference and main complications during hospitalization (P ＞0.05).Pre5 group had higher incidence of small for gestational age (SGA) than late5 group (16/18 vs.25/40,P =0.037),while the EUGR ratio at discharge (14/18 vs.21/40,P =0.061) was similar.When compared with pre5 group,late5 group had larger amount of initial enteral feeding volume [4.4 ml/(kg · d) vs.2.4 ml/(kg · d),P =0.014] and feeding volume at the end of the first week [(19.8 ± 16.0) ml/(kg · d) vs.(12.2 ±9.5) ml/(kg · d),P =0.036].Similarly,the starting dose of amino acids in parenteral nutrition [2.0g/(kg· d) vs.1.0 g/(kg· d),P＜0.001],maximum dose of amino acids [4.0g/(kg.d) vs.3.5 g/(kg · d),P ＜ 0.001],total calories at the end of the first week [(82.6 ± 12.6) kcal/(kg · d) vs.(71.1±15.2) kcal/(kg· d),P=0.004] and the second week [(103.7 ±19.8) kcal/(kg· d) vs.(92.3 ± 17.9) kcal/(kg · d),P =0.041],the weight gain velocity from birth to discharge [(18.7 ± 2.9) g/(kg.d) vs.(16.9±2.8) g/(kg· d),P=0.031] and change of Z scores (AZ) [-0.6 (-1.0,-0.4) vs.-1.2 (-1.6,-0.8),P =0.004] showed significantl differences between the two groups,with better outcomes in late5 group.However,the duration of parenteral nutrition,the total amount of amino acids,the time reaching total enteral feeding,the length of hospital stay were similar between the two groups.Ten cases(61.1％)of infants in pre5 group were breastfed,and four of them used human milk fortifier (HMF) (fortified rate was 22％).32 cases (80％) in late5 group were breastfed and 23 cases used HMF (fortified rate was 57.5％).The time to initiate HMF in the late5 group was at (30.2 ± 13.2) days,and human milk amount was (89.9 ± 34.5) ml/kg,fortified duration was (32.8 ± 15.7) days.Conclusion The enteral feeding strategy were more vigorous in the last 5 years than before,the initial feeding volume,the increasing rate,the initial dosage of amino acid,and maximum dosage of amino acid had been increased.Human milk and HMF of preterm infants were preferred.The vigorous nutritional support strategy were effective for the weight gain of ELBW infants without obvious side effects during hospitalization.

Objective To understand the differences of virulence genes and molecular typing in Campylobacterjejuni isolates from poultry products and diarrhea patients in Shenzhen.Methods According to specific primers,four virulence genes (cdtB,cadF,flaA,virB1 1 )of C.jejuni were detected by polymerase chain reaction (PCR).Molecular typing for C.jejuni strains was performed by Pulsed-field gel electrophoresis (PFGE).Results There were no differences of gene distribution (cdtB+,cadF+,virB1 1-)between isolates from poultry products and diarrhea patients.Two virulence genes of cdtB and cadF were found in all of ten C.jejuni strains lacking virB1 1 .The carriage rate of flaA in food-borne isolates (3/5 )was higher than those in patient isolates (2/5).In the PFGE map,the clustering analysis of C.jejuni strains showed that a total of 5 to 9 DNA bands were observed in ten strains through the digestion of Sam I.There was high homology (above 85%) between food-borne isolates and patients isolates,but the distribution of flaA in these highly homologous strains was differ-ent.Conclusion So far,C.jejuni strains with cdtB,cadF and flaA were present in Shenzhen,and showed high diversity and homology.This implies that the occurrence of diarrhea in patients with C.jejuni was associated with the contaminated poul-try products by this pathogen.Their findings can provide basic data and evidences about diarrheal disease caused by food-borne C.jejuni for the local region.
