The aim of the study is to investigate the effect of nardosinone (Nar) on neuronal injury induced by oxygen-glucose deprivation (OGD) in primary cortical cultures isolated from embryos at gestational day 14. MTT method was used to determine the dosage regimen of Nar in primary neuronal cultures and observe the influence of Nar on the neurons suffering OGD; Western blotting analysis was used to detect expressions of protein kinase A (PKA), Ras related protein 1 (Rap1), mitogen-activated protein kinase kinase 1 (MEK1) and phospho-extracellular signal-regulated kinase 1/2 (p-ERK1/2) of OGD-injured or uninjured primary cultured neurons after Nar treatment. Results showed that Nar (50 and 100 micromol x L(-1)) improved the cell viability during OGD damage (P < 0.01) and increased the expression of PKA, Rap1, MEK1 and p-ERK1/2 in injured neurons. Additionally, elevations of PKA, Rapl, MEK1 and p-ERK1/2 in uninjured neurons were caused by Nar (50, 100 and 200 micromol x L(-1)) with a dose-dependent tenclency as well (P < 0.01). In conclusion, Nar could protect against the neuronal injury exposed to OGD, which may be relevant to the promotion of PKA and ERK signaling pathway.

Objective To discuss the image characters and the technical manipulation of endovascular embolization for cerebral AVM with bleeding. Methods The cerebral AVMs with bleeding in 56 cases were confirmed by CT, MRI, and whole cerebral DSA. Depended on the nidus of AVM, the superselective endovascular embolization with NBCA or embolization combined with radiological surgery was chosen. Results The nidus was eliminated for 100% in 36 cases after embolization for 1 to 3 processes. The rebleeding was found in 2 cases with new growth and survival aneurysm in nidus during the follow-up period and treatment with X-knife, and was cured by the second embolization. Conclusion The main causes of AVM bleeding included aneurysm and aneurysm-like dilation beside and located at the nidus, fine draining veins, and growth in the ventricles. To prevent the brain from bleeding, it is favourable to eliminate the aneurysm in AVM during embolization.

Objective To characterize the relationship between such phenotypes and the patterns of genetic mutations in the corresponding resistance genes in drug-resistant Mycobacterium tuberculosis (MTB)isolates in Shenzhen of China during 2007-2008.Methods According to standard of WHO,International Union Against Tuberculosis and Lung Disease(IUATLD),136 strains of MTB were collected by performing drug sensitivity test(DST)to isoniazid,rifampicin,streptomycin,ofloxacin and kanamycin on Lowenstein-Jensen in 1%proportion method.Genetic mutations in the corresponding resistance genes (rpoB,katG,rpsL,rrs1,gyrAB,rrs2)in these MTB isolates were identified by PCR,followed by DNA sequencing of the purified PCR products.The minimal inhibitory concentration(MIC)values of the aforementioned anti-tuberculosis drugs were determined for these MTB clinical isolates by two-fold dilution method in vitro.Results A total of 123 isolates were collected,73 isolates were drug resistant.50 isolates were drug susceptible.Among the isolates that were resistant to isoniazid,rifampicin,streptomycin.ofloxacin and kanamycin,the proportion of isolates that harboured mutations in the respective genes was 84.6%,93.6%,65.9%,100%,61.1%.For katG gene,the mutation detected were S315T or S315N.For rpoB,the most frequently found changes were S531L(30/44,68.2%)and H526D(9/44,20.5%)or H526R(1/44,2.3%).The reported mutations that K43R and KS8Q were founded in the rpsL locus and 491C→T and 513A→C were founded in the rrs1 gene related with streptomycin-resistant strains.For gyrA,all gyrA mutations were clustered in codons 90,91,and 94 apart from the S95T that was natural polymorphism.accounted for 81.1% of the ofloxacin-resistant isolates,and condon 91 was the most frequently mutated.No mutation were found in gyrB.The most frequent substitution were 1400 A→G(9/11,81.8%)and 1483 G→T(2/11,18.2%)in a specific region of the rrs2 gene related with kanamycin-resistant strains.No mutations except S95T of gyrA detected in the drug-susceptible isolates.The MIC values of clinical drug-resistant strains that the same drug-resistant group contains a different resistance phenotype are basically the same with the relevant resistance genes in the same mutation.Associated resistance mutations in different sites varied significantly with their MIC values.Conclusion The mutation characterization of drug-resistant and drug-suscep-tible isolates of MTB have been shown to vary according to geographic region,phenotypic characteristics exist difference in resistance levels due to different muntants of drug-resistant gene.
