Objective To investigate the effects of breviscapine injection on intestinal mucosal barrier damage induced by intestine ischemia-reperfusion (IIR). Methods 44 old SD rats were randomly divided into four groups:sham,intestine ischemia-reperfusion(IIR),EB+IIR,LN+IIR. Breviscapine injection 20 mg/(kg·d) was given intraperitoneally in EB+IIR group. L-NAME(100 mg/kg)was given intravenously 30 min before surgery in LN+IIR group. Rats were subjected to superior mesenteric artery occlusion consisting of 45 min of ischemia and 4 h of reperfusion;sham laparotomy served as controls. Intestine pathology was assayed by H&E staining. Concen-trations of SIgA,iNOS,eNOS and NO in intestinal mucosa,also endotoxine in plasma,were determined by ELI-SA. Results IIR induced serious intestinal mechanical and immune barrier damage ,evidenced as poor intestine pathology,depression of intestinal SIgA and eNOS levels,elevation of intestinal iNOS/NO levels. However,brevis-capine injection pretreatment could promote eNOS/NO production ,down-regulated iNOS expression ,leading to ele-vating SIgA concentration in intestine ,attenuate endotoxemia induced by IIR. The protection was canceled when application of L-NAME. Conclusion Breviscapine pretreatment attenuates ischemia-reperfusion-induced intestinal mucosal barrier damage via promoting eNOS/NO production.

Objective To investigate the sedative effect of propofol combined with different doses of midazolam in patients undergoing long-time microsurgeries.Methods Forty ASA(American Society of Anesthesiologists)Ⅰ～Ⅱ patients were randomly divided into 4 groups.Normal saline(NS) 2 mL was administered in groupⅠ,while midazolam 0.01,0.02 and 0.04 mg/kg was administered in groupⅡ,Ⅲ,Ⅳ respectively.one min later,propofol was infused at a rate of 5～10 mg/kg?h combined with midazolam based on the abovementioned dosage per hour for groupⅡ,Ⅲ,Ⅳ respectively.Taking auditory evoked potential index(AAI) as a parameter,after it decreased to 40,the infusion rate of propofol was adjusted to keep AAI at the level of 30～45,and maintained the level by infusing propofol and midazolam for 5 hours.The dosage of propofol required for induction and maintenance was recorded.The emergence time and whether patients had awareness during the operation were recorded after the infusion stopped.Results At the target sedative level of AAI 30～45,the Observer's Assessment of alertness/sedation(OAA/S) score of all patients in the four groups reached 0～1.The induction period was obviously shortened and the propofol dosage was dramatically reduced in group Ⅱ～Ⅳ as compared with groupⅠ.At the stage of maintenance of sedation,the dosages of propofol in both groupⅠandⅡ were larger than those in group Ⅲ and Ⅳ.The emergence time in group Ⅳ was dramatically longer than the other groups(P

Objective To identify one umbilical blood sample with abnonnal gap-PCR products of three bands of α2,-α3.7 and-SEA.further family pedigree were analyzed for the source of genetic variations,Methods One fetal umbilical blood sample was drawn from a woman of 24-weeks pregnancy.Gap-PCR for α-thalassemia was routinely conducted and abnornlal three bands of α2.-α3.7 and-SEA were observed.which could not be interpreted according to the kit manual and suspected as rare variation.With informed consen,DNA samples from the parents and grandparents were obtained for further study.Singleplex andnested PCR techniques were utilized to analyze the molecular characteristics of DNA samples from this fetus and its parents and grand-parents.Results Hematological phenotype study showed that fetal Hb Ban's was 7.6%,and its mother and maternal grandfather were both with typical α-thalassemia.while its father,grandfather and grandmother and maternal grandmother are without abnormal hematological change.Molecular study showed that fetal blood DNA was a heterozygosity for HKaa and-SEA.its father and grandfather are both HKαα/αα,its mother and maternal grandfather are both-SEA/aa,its grandmother and maternal grandmother are with both normal alleles of αα/αα.Then after genetic counseling the fetas was saved and iS a she baby now.Conclusion ThroUgh careful molecular tests one case of prenatal heterozygosity of HKαα/-SEA was identified,and the fetus is kept successfully through careful clinical counseling.

HepG2 ceils were treated with various concentrations of tumor necrosis factor-or (TNF-α) for 24 hours. RT-PCR and Western blot were used to measure protein tyrosine phosphatase-1 B(PTP-1B)expression, and luciferase reporter assay was used to detect NF-kB activity. The results showed that treatment of HepG2 cells with TNF-α for 24 hours led to upregulation of PTP-1B and NF-kB activity in a dose-dependent manner. Inhibition of NF-kB by PI)TC significantly attenuated TNF-α-induced PTP-IB expression in HepG2 cells. Thus, the transactivation of NF-kB seems to play an important role in the expression of PTP-1B in HepG2 cells induced by TNF-α.
