This text involved with a pre-enrichment medium for the simultaneous recovery of Salmonella spp.,Escherichia coli and Staphylococcus aureus.This medium is named buffered saline broth(BSB),which contains peptone 10g,beef exact 3g,disodium hydrogen phosphate 9g,potassium dihydrogen phosphate 1.5g,additive 50g,deionized water 1 000mL,pH7.2.1cfu per one milliliter of Salmonella spp.,Escherichia coli and Staphylococcus aureus in saline were stimutaneously added to 97 mL of BSB,buffered peptone water,lactose broth,nutrient broth,Escherichia coli broth,rappaport-vassiliadis enrichment broth,7.5% sodium chloride enrichment medium,respectively,and incubated for 18h at 37℃.The results showed BSB was the best enrichment medium,in which Salmonella spp.,Escherichia coli and Staphylococcus aureus multiplied at nearly same speed,and reached at 10~6 、10~6 、10~7 cfu/mL,respectively.Multiplex PCR produced specific amplicons of expected sizes,284bp for Salmonella spp.invA gene,622bp for Escherichia coli phoA gene,484bp for Staphylococcus aureus nuc gene.In contrast,the three bacteria couldn't multiply harmoniously in the other six media.So BSB might be considered as the medium,which could enrich above mentioned three bacteria.

Objective To observe the clinical effect by using insulin detemir therapy in children and adolescents with type 1 diabetes mellitus(T1DM).Methods Thirty children and adolescents with T1DM were divided into 2 groups to receive Humulin R and Determir(observation group,n =15) or Humulin R and neutral protamine hagedorn (NPH) (control group,n =15)insulin therapy.Daily insulin dose,glycemic variability,incidence of non-severe and severe hypoglycemia events after the institution of insulin therapy were collected.Results The daily doses of insulin were (1.16 ± 0.30) U/kg in the observation group and(1.21 ± 0.35) U/kg in the control group,respectively.There was no clinically important change between 2 groups(t =0.526,P ＞ 0.05).Within-subject variation in fasting plasma glucose was significantly lower in observation group(29％)than that in control group(65％) (t =5.296,P ＜0.01).One case of severe hypoglycemia event occurred in the observation group,but 5 cases occurred in the control group(t =4.863,P ＜ 0.0l).Two cases of nocturnal hypoglycaemia(22:00-7:00) events occurred in the observation group,7 cases occurred in the control group(t =4.506,P ＜ 0.01).Conclusions Institution of insulin detemir therapy is associated with low within-subject variation in fasting plasma glucose and decreased rates of severe and nocturnal hypoglycemia while dose of insulin did not increase.This makes insulin detemir a valuable new tool for the treatment of children and adolescents with T1 DM.

Objective To explore the serum level of gentamycin for orally in children with serious illness.Methods The serum level of gentamycin in 41 children who were in serious illness [multiple organ dysfunction(MODS)group with 21 cases and non-MODS group with 20 cases ] were monitored and the patients were treated with select decontamination of the digestive tract(SDD) from October 2004 to April 2005.Dosage:10 mg/(kg?d),orally taken three times(every 8 hours) one day.The blood after taking the drug one hour later in the fourth day was selected and the serum level of getamycin was monitored.Results Thirty-six children of 41 cases serum level of gentamycin were negative and 5 children(4 in MODS group and 1 in non-MODS group) who had alimentary tract hemorrhage were masccline in serum after taking gentamycin one hour later in the forth day.The absorption of gentamycin from enteric after orally was not(rela)-ted to MODS.There were statistics value between the gestrintestinal tract ulcer and serum level of gentamycin.Conclusions The safety for treating the children in serious illness with gentamycin for SDD is obvious.But we suggest to monitor the serum level of gentamycin for who has severe alimentary tract hemorrhage together with insufficiency of liver and kindey.

Aim To observe the improvement effects of parecoxib on ventricular remodeling after acute myocardial infarction in rats and its influence on PI3K/Akt signaling pathway.Methods Forty male Sprague-Dawley rats were randomly divided into five groups(n=8):sham operation group (group S), ventricular remodeling model group(group R), low dose of parecoxib group(group P1), middle dose of parecoxib group(group P2), and high dose of parecoxib group(group P3).A myocardial infarction model was established by ligating the left anterior descending branch(LAD) of coronary artery in group R, group P1, group P2 and group P3.One day after the operation,the rats were given intraperitoneal injection of 4,8,12 mg·kg-1 parecoxibin Group P1, group P2 and group P3,respectively, for two weeks.The same volume saline was given in group S and group R.Four weeks later, LVSP, LVEDP,+dp/dtmax,-dp/dtmax were monitored.The hearts were harvested to calculate left ventricular hypertrophy index.The pathological change of heart was examined with an optical microscope.The expressions of atrial natriuretic peptide(ANP) mRNA and brain natriuretic peptide(BNP) mRNA were detected by RT-PCR.The expression of PI3K,Akt,P-Akt and caspase-3 was detected by Western blot.Results Compared with group S, the cardiac function was decreased, the left ventricular hypertrophy index, the expression levels of ANP,BNP mRNA, caspase-3 were increased, and the expression levels of PI3K, P-Akt were reduced in group R(all P<0.05).Compared with group R, the cardiac function was ameliorated, the left ventricular hypertrophy index were reduced in group P2 and group P3(all P<0.05).The expression levels of ANP,BNP mRNA, Caspase-3 were decreased, and the expression levels of PI3K and P-Akt were increased in group P1,group P2 and group P3(all P<0.05).Conclusions Middle and high doses of parecoxib can mitigate the process of ventricular remodeling after myocardial infarctionand improve the myocardial function, and its underlying mechanism may be related to activating PI3K/Akt signaling pathway.

Aim To investigate the role of matrix metalloproteinase-9 down-regulation in the learning and memory dysfunction induced by propofol treatment in rats.Methods 7-day-old SD rats were randomly divided into three groups(n=18):control group(NS group) and repeated doses of propofol group(RP group) was intraperitoneally injected with normal saline and propofol respectively for consecutive seven days, single dose of propofol group(SP group) were intraperitoneally injected with normal saline first for consecutive six days, and then injected with propofol on 7th day.The blood gas and glucose levels were monitored of six rats randomly selected from each group.Morris water maze was conducted to test the learning and memory functions of the remaining rats.The expression of MMP-9, BDNF and caspase-3 was detected by Western blot, and the hippocampal neuron apoptosis was determinated by TUNEL staining.Results Compared with NS group and SP group, the escape latency in RP group was prolonged significantly, exploration time and the number of crossing the platform in RP group were markedly decreased(P<0.05).The expressions of MMP-9 and mBDNF in RP group declined, but the expression of proBDNF and the ratio of proBDNF/mBDNF in RP group were higher than those in NS group and SP group(P<0.05).Compared with NS group and SP group, the number of apoptotic neurons and the expression of cleaved-caspase-3 in RP group were increased significantly, but the expression of pro-Caspase3 in RP group was reduced(P<0.05).There was no difference between SP group and NS group regarding all the results(P>0.05).Conclusions Repeated exposure to propofol can lead to a decline in long-term learning and memory functions in neonatal rats, which may be related to the down-regulation of MMP-9 expression, proBDNF and mBDNF conversion disorder in hippocampus and the apoptosis of hippocampal neurons.However, single exposure to propofol has no significant effect.
