Objective To develop a rapid,sensitive,specific and accurate quantitative duplex real-time PCR assay for detection of Listeria monocytogenes and Shigella.Methods Two sets of specific primers and probes were selected according to Listeria monocytogencs hly gene and Shigella ipaH gene.The target hly and iPaH fragments were amplified by PCR,and used to construct recombinant pGEM-T-hly and pGEM-T-ipaH respectively.The two recombinant circular plasmid DNAs were linearized with EcoR I that did not cut within the target DNA fragment.The ten-fold dilutions of plasmid were subjected to the standard quantitation curve in duplex real-time PCR assay.Various genomic DNAs of Listeria innocua,Listeria weshimeri,Salmonella,Staphylococcus aureus,Bacillus subtilis,Escherichia coli and Proteus were used as negative controls to confirm the specificity of duplex real-time PCR assay.The assay was also used to detect Listeria monocytogenes and Shigella in artificially contaminated sterilized skim milk.Results The recombinant plasmids were constructed successfully,hly probe(rAM and TAMRA double labelled)and ipaH probe (HEX and TAMRA double labelled)were used to develop an optimized PCR successfuliv.Conclusion The selected primers and probes showed high specificity for these two target bacteria,the linear range of the assay was good(105-101 copies/μl,R2≥0.998)and sensitivity Was 10 copies/PCR.Following a DNA extraction method which combined EZ Spin Colum Genomic DNA Isolation Kit(BBI)/Phenol-chloroform,the sensitivity of assay Was 102CFU/ml for both Listeria monocytogenes and Shigella in artificially contaminated sterilized skim milk,which equivalents to 10 CFU/PCR.

BACKGROUND: Orphanin (OFQ) is associated with ischemia/hypoxia,which may play an important role in the production and development of fetal distress and neonatal asphyxia.OBJECTIVE: To observe the change of OFQ content in hypothalamus and peripheral blood of intrauterine ischemia/hypoxia fetal rats and analyze the role of OFQ in the perinatal ischemia/hypoxia.DESIGN: Randomized controlled animal trial.SETTING: Department of Obstetrics and Gynecology, Changhai Hospital of the Second Military Medical University of Chinese PLA.MATERIALS: The experiment was performed at the Department of Obstetrics and Gynecology, Changhai Hospital of the Secon d Military Medical University of Chinese PLA from May 2002 to September 2003. A total of 12 Wistar female rats, with the mean body mass of 260 g were selected and fed routinely [provided by the experiment animal center of this university, number of certificate scxk(Hu)2002/0006].METHODS: The 12 female rats were randomized into three groups: control group, ischemia/hypoxia for 10 minutes group, ischemia/hypoxia for 20 minutes group with 4 rats in each group. Female rats in each group were pregnant. On day 21 of pregnancy, female rats in each group were cut the belly open, and the uterine vessels were incarcerated for 10 minutes in the ischemia/hypoxia for 10 minutes group with 21 fetal rats and 20 minutes in the ischemia/hypoxia for 20 minutes group with 17 fetal rats, respectively. Fetal rats were directly obtained from control group with 19 ones. None of fetal rats died. All the fetal rats received Apgar score and decapitation. The blood of trunk was collected and the whole brain was obtained. OFQ content in hypothalamus and peripheral blood was measured with radioimmunoassay.MAIN OUTCOME MEASURES: OFQ content in hypothalamus and peripheral blood of fetal rats in each group.RESULTS: Totally 57 rats were involved in the result analysis. ①The levels ofOFQ in hypothalamus and peripheral blood were (71±14) pg/g and (31±7) ng/L in ischemia/hypoxia for 10 minutes group, (114±21) pg/g and (58±11) ng/L in ischemia/hypoxia for 20 minutes group, (48±9) pg/g and (19±4) ng/L in the control group. Compared with the control group, the levels of OFQ in hypothalamus and peripheralblood increased in the ischemia/hypoxia for 10 minutes group and ischemia/hypoxia for 20 minutes group (P＜ 0.05, P ＜ 0.01), and it in ischemia/hypoxia for 10 minutes group was significantly higher than that in ischemia/hypoxia for 20 minutes group (P ＜ 0.05). ②The score of Apgar was lower in the two groups than in the control group (P ＜ 0.01 ), of which it was lower in the ischemia/hypoxia for 20minutes group than in the ischemia/hypoxia for 10 minutes group (P ＜ 0.05).CONCLUSION: The perinatal ischemia and hypoxia can induce the increase of OFQ content in hypothalamus and peripheral blood.

BACKGROUND: Endogenous opioid peptide is an important medium and regulator that participate in many physical and pathologic processes of the body. Its relationship with fetal encephalopathy has attracted much attraction.OBJECTIVE: To evaluate the role of endogenous opioid peptides (EOP) in fetal distress.DESIGN: A case-control observatory study based on healthy pregnant women.SETTING: Wards of the Department of Obstetrics and Gynecology of Changzheng Hospital Affiliated to Second Military Medical University of Chinese PLA.PARTICIPANTS: Eighty-three healthy women who were hospitalised in Changzheng Hospital and Changhai Hospital affiliated to the Second Military Medical University of Chinese PLA and met the inclusion criteria. Among them, 40 were normal healthy pregnant women(the control group) and 43 were healthy pregnant women with fetal distress(the fetal distress group).METHODS: Radioimmunoassay was used to measure the levels of blood EOP(β-endorphin, dynorphin A1- 13 and leu-enkephalin) of the venous blood of the pregnant women in fetal distress group and the control group and the EOP level in the umbilical blood of the newborns. Also, blood gas analysis of the blood from the umbilical artery was conducted.MAIN OUTCOME MEASURES: The levels of EOP in the venous blood of two groups of pregnant women and the umbilical blood of newborns and the correlation of EOP level with fetal distress.RESULTS: The levels of the umbilical artery blood EOP(β-endorphin,dynorphin A1-13 and leu-enkephalin) in the fetal distress group[(453± 68 ) ng/L, (242 ± 33)ng/L, and(498 ± 68)ng/L respectively] were significantly higher than those in the control group[ (251 ± 39) ng/L, (103± 22 )ng / L and(322 ± 40 )ng / L respectively ( t = 2. 713,2. 762, P＜ 0.01; t = 2. 132, P ＜ 0.05 ) ]. The umbilical artery blood gas analysis;pH was (7.0 ± 0. 1 ) , PO2 was ( 1.7 ± 0.6) kPa, PCO2 was (8.9 ± 0. 7) kPa.The levels of β-endorphin were negatively correlated with pH and PO2 of the umbilical artery blood(r= -0.418 and -0.437, P ＜ 0.01), but they were positively correlated with PCO2( r = 0. 442, P ＜ 0. 05) . The level of dynorphin A1-13 was negatively correlated with pH and PO2( r = -0. 337,-0.383, P ＜ 0.05), but it was positively correlated with PCO2(r= 0. 346, P ＜ 0. 05). There was no significant difference among the three kinds of blood EOP of the two groups( P ＞ 0.05).CONCLUSION: EOP participates in the pathological progress of the fetal distress and was closely correlated with the occurrence and development of the fetal distress. This finding has a reference value for early rehabilitation and intervention after the fetal was born that can be tested quantitatively.
