A method was developed for the determination of four sulfa antibiotics in groundwater, soil and excreta using solid phase micro extraction disks coupled with high performance liquid chromatography. The influence of eluent, different solid phase micro extraction membranes on the recovery of sulfa antibiotics in groundwater was investigated and it was found that when using the mixture of methyl alcohol and 1 . 0% formic acid as eluent, HLB ( divinyl benzene-N-vinyl pyrrolidone polymer ) as extraction membranes, an optimal enrichment effect was obtained. Different pretreatment methods for the 3 kinds of samples abovementioned were also examined. It was found that the signal response values obtained by using mixture of methyl alcohol and 1 . 0% formic acid as base solution of standard or sample solution was higher 8-10 times than that by using methyl alcohol only. Under the optimal conditions, good linear relationships were obtained in the sulfa antibiotics concentrations of 0 . 005-10 . 0 mg/L with the correlation coefficients>0 . 9999;The detection limits of sulfathiazole ( ST ) , sulfadiazine ( SM ) , sulfamethazine ( SM2 ) , sulfamethoxazole ( SMX ) were 1 . 08 , 3. 56, 4. 63 and 1. 84 ng/L(S/N=3), respectively. The enrichment factors for four sulfa antibiotics were 4000 times with solid phase micro extraction disks. The RSD of matrix spiked samples were 0. 1%-0. 4%(n=7). The proposed method was applied to the determination of the four sulfa antibiotics in groundwater, soil and excreta with spiked recoveries of the four sulfa antibiotics in the range of 69 . 80%-117 . 60%.

Objective:The present study aimed to conduct a clinical analysis of nosocomial infections in hospitalized cancer pa-tients and propose effective precautionary measures. Methods:We retrospectively analyzed 56,430 cases of discharges from the Cancer Institute and Hospital of Tianjin Medical University between January and December 2012. Results:Among 825 cases, the rate of noso-comial infections was 1.46%;46.42%of the patients aged>60 years. The highest infection rate was observed in the Medical Depart-ment of Stomach Cancer. The highest composing rate was recorded in the Department of Hepatobiliary Cancer. The major pathogenic bacteria were Gram-negative bacilli;fungal infections were relatively rare. The most vulnerable body parts were the abdomen and diges-tive tract, which were mainly infected by pathogenic Escherichia coli. Conclusion:Healthcare workers should consider the importance of influencing factors and take precautionary measures to reduce the rate of nosocomial infections in cancer patients.

OBJECTIVETo investigate the maturation of individual bones on the hand and wrist in children with central precocious puberty (CPP) and idiopathic short stature (ISS).

METHODSHand and wrist films of 25 children with CPP, 29 children with ISS and 21 normal controls were evaluated by conventional Greulich-Pyle (GP) atlas method and individual bone assessment method, in which all twenty bones of the hand and wrist were evaluated based on GP atlas, including 2 radius and ulna, 7 carpal bones, 11 metacarpal and phalangeal bones, the average bone age (BA) was calculated. The differences in groups were analyzed by independent samples t test. The differences between the two methods were analyzed by paired sample t test. The differences between BA and chronological age (CA) were analyzed by ROC with SPSS 17.0.

RESULTSCompared with the normal control group, the advance of BA in the CPP group was 0.70-2.26 y (1.48 ±0.78) by the GP atlas method, while that was 0.28-2.00 y(1.14 ±0.86) by the individual bone evaluation method. In all twenty bones, the advance of metacarpal and phalangeal BA was the greatest [0.34-2.06 y(1.2±0.86)]. In the ISS group,the delay of BA was 0.47-2.91 y(-1.69±1.22) by the GP atlas method, while that was 0.48-2.50 y (-1.49±1.01) by individual bone evaluation method.The delay of carpal BA was the greatest [0.59-2.73 y(-1.66±1.07)] in all twenty bones. In the ISS group and the normal control group, there were no statistic differences between the two methods. In the CPP group, statistic difference was found between two methods. There were no statistic differences for the areas under ROC curves between two methods.

CONCLUSIONThe advance of metacarpal and phalangeal BA is the greatest in CPP group and the delay of carpal BA is the greatest in ISS group.Both methods provide diagnostic information for bone age in CPP and ISS children.

Objective To explore the effect of umbilical cord mesenchymal stem cells with positive human leukocyte antigen(HLA)-G on inducing the production of regulatory T cells(Treg) in vitro.Methods Umbilical cord mesenchymal stem cells were isolated from umbilical cord of neonates. PEGFP-N1-HLA-G plasmid was transfected into the human umbilical cord mesenchymal stem cells by liposome transfection, as PEGFP-N1-HLA-G group. PEGFP-N1 empty vector plasmid was transfected into the human umbilical cord mesenchymal stem cells, as PEGFP-N1 group. The human umbilical cord mesenchymal stem cells without empty vector under the same conditions were set as blank control group. Markers of the umbilical cord mesenchymal stem cells were detected using flow cytometry. The expression of HLA-G protein in each group of cells was identified by Western Blot. After mixed-culturing with CD4+T cells in peripheral blood of healthy subjects for 24 h and 48 h, the proportion of CD4+CD25+Foxp3+Treg in total T cells of each group was detected by flow cytometry. Results CD45, CD34 and HLA-DR presented negative expression on umbilical cord mesenchymal stem cells, while CD29, CD44 and CD105 presented positive expression. HLA-G protein could be expressed in the PEGFP-N1-HLA-G group, which had statistically significant difference compared with the blank control group and PEGFP-N1 group (both P<0.01). After PEGFP-N1-HLA-G group and CD4+T cells were mixed-cultured for 24 h and 48 h, CD4+CD25+Foxp3+Treg accounted for (15.3±1.9)% and (14.3±2.1)% of the total T cells respectively, both of which presented statistically significant difference compared with the blank control group and PEGFP-N1 group (all P<0.05). Conclusions Umbilical cord mesenchymal stem cells with HLA-G gene modified can effectively induce the production of CD4+CD25+Foxp3+Treg in vitro.
