Objective To study the expression of cyclooxypenase-2(COX-2),prognosis of patients and the correlation between COX-2 and CD_(105)in osteosarcoma.Methods The expression of COX-2 and CD_(105)in human osteosarcoma was detected with immunohistochemistry.Then to count the microvessl density (MVD)were marked with CD_(105),The prognosis of the patients with osteosarcoma was analyzed by Cox multi- variate survival analysis.Results The positive rate of COX-2 expression was 77.5 %,The expression of COX-2 was positively correlated with surgical grade and metastasis of osteosarcoma;There were significant difference between surgical grade Ⅰ and Ⅱ b、grade Ⅰ and Ⅲ(P0.05);Metastatic cases had higher MVD than those without metastasis(P

Objective To observe the cell proliferation inhibition of DNA methyltransferase (DNMT) inhibitors decitabine (DAC) combined with daunorubicin (DNR) in human leukemia cell line HL-60.Methods The effects of DNR and DAC were examined in HL-60 cells by cell viability using MTT method,and cell death using flow cytometric (FCM).Results DAC,DNR single drug application showed their effects on cell proliferation was dependent of dose and time,the inhibition effect of combined treatment group was much clearer [inhibition ratio of 72 hours was (80.23±1.71) ％,P ＜ 0.001].The highest apoptosis rate was at 5.0 μmol/L DAC combined with 1.0 μmol/L DNR for 72 hours,which was statistic significant (F =30.199,P ＜ 0.001).Combinations of different concentrations of DAC and DNR increased expression of PTEN mRNA in concentration-dependent manner,which was significantly higher than the control group and DNR single drug group (F =578.218,P ＜ 0.001).Conclusions DAC can significantly inhibit the proliferation of HL-60 cells and induce apoptosis,synergistic effect can be observed when DAC combined with DNR.The underlying mechanism can be due to DAC demethylation effect to increase PTEN mRNA expression.

Objective To investigate the group B streptococcus( GBS)colonization rate and the relationship between vaginal colonization of GBS and the pregnancy outcome. Methods Five hundred and twenty cases pregnant women were selected as our subjects. Microbiological culture was used for culture of GBS in 1 / 3 of vagina and rectus before delivery,other samples from different sites after delivery(including neonatal throat,ear and placenta). Results (1)The GBS carrier rate in 520 pregnant women was 10. 19%(53 / 520). (2)GBS carrier rate in neonatal was 8. 85%(46 / 520). The carrier rate of neonatal whose mothers also carried GBS was 22. 64%(12 / 53),higher than that of non-carrier mothers(7. 28%(34 / 467),χ2 = 8. 192,P < 0. 05) . The rate of pneumonia and the upper respiratory tract infection of neonatal with GBS-carrier-mother were 20. 75%(11 / 53)and 18. 87%(10 / 53),higher than that of non-carrier mothers(8. 57%(40 / 467)and 4. 71%(22 / 467)). The pneumonia rate and upper respiratory tract infection of GBS positive neonatal were 21. 73%(10 / 46)and 19. 56%(9 / 46),higher than GBS negative one(8. 65%(41 / 474);4. 85%(23 / 474)). and there were significant differences(χ2 = 8. 121,15. 717;P < 0. 05).(3)The incidence of intrauterine infection and fetal distress of neonatal with GBS( + )mother were 47. 17%(25 / 53),15. 09%(8 / 53),significantly higher than that of negative(7. 07%(33 / 467),4. 71%(22 / 467)),and the differences were statistically significant( χ2= 77. 248,9. 440;P < 0. 05). But there were the similar incidence in term of premature rupture of fetal membranes,premature occurrence rate between GBS positive and negative mothers( 28. 30%( 15 / 53 ) vs. 28. 48%(133 / 467;3. 77%(2 / 53)vs. 2. 36%(11 / 467);χ2 = 0. 001,0. 393;P > 0. 05). The rate of GBS positive with mycotic vaginitis,placenta previa ratio were 39. 62%(21 / 53),7. 55%(4 / 53),higher than that of GBS negative one(20. 56%(96 / 467),1. 93%(9 / 467)),and the differences were statistically significant(χ2= 9. 922,6. 168,P < 0. 05). Conclusion Maternal GBS carrier at 35 - 37 weeks of gestation can lead to adverse pregnancy outcome by increasing intrauterine infection fetal distress and neonatal infections. Screening of GBS should be performed routinely in late gestation.

Objective: To systematically review the association between apolipoprotein E (APOE) gene polymorphism and cerebral infarction in Chinese Han population. Methods: The pertinent literature of the gene polymorphism and the case control studies of cerebral infarction in Chinese Han population were researched comprehensively by combined application of 5 effective retrieval approaches. The odds ratio (OR) of the genotype distribution in cerebral infarction group and control group were calculated. Results: A total of 1986 patients with cerebral infarction and controls were included in the meta-analysis. After the data were pooled, the OR values of ApoE ε2/ε3, ApoE ε3/ε3, ApoE ε2/ε4, ApoE ε3/ε4, and ApoE ε4/ε4 were 0. 59 (95% CI, 0.44-0. 79), 0. 52 (95% CI, 0. 40-0.69), 2.00 (95% CI, 1.22-3.28), 2.77 (95% CI, 1.60-4.81 ), and 4. 66 (95% CI, 1.61-13.48), respectively. Conclusions: ApoE ε2/ε4, ApoE ε3/ε4 and ApoE ε4/ε4 genotypes are the risk factors of cerebral infarction. ApoE ε2/ε3 and ApoE ε3/ε3 genotypes are the protective factors of cerebral infarction.

Aim To explore the effect of connexin 43 ( Cx 4 3 ) on acquired gefitinib-resistance in human non small cell lung cancer ( NSCLC ) . Methods HCC827 GR, a gefitinib-resistant ( GR) NSCLC cell lines from their parental cells was established by gradually in-creasing the concentration of gefitinib. Gefitinib effica-cy in HCC827 and HCC827 GR cells was detected by MTT assay. Expression of Cx43 mRNA in HCC827 and HCC827 GR cells was determined by RT-PCR. The protein expressions of Cx43 and phospho-Akt ( p-Akt) in these cells were detected by Western blot. The func-tional gap junction intercellular communication ( GJIC ) was measured by parachute assay. The cellular locali-zation of Cx43 protein was evaluated by immunofluores-cence staining. Results MTT assay showed less ge-fitinib cytotoxicity in HCC827 GR cells than that in their parental cells with IC50 of (10. 84 ± 0. 021) μmol ·L-1 versus (0. 07 ± 0. 019) μmol·L-1 , respective-ly. Moreover, both mRNA and protein expressions of Cx43 in HCC827 GR cells were significantly lower than those in HCC827 cells ( P<0. 05 ) . However, the p-Akt protein in HCC827 GR cells was obviously higher than that in HCC827 cells ( P<0. 05 ) . Furthermore, treatment with LY294002 caused a significant reduced p-Akt expression, but a significant increased Cx43 ex-pression in HCC827 GR cells. Moreover, no detecta-ble GJIC was found in HCC827 and their GR cells with or without RA ( a well-defined GJIC enhancer ) treat-ment. Immunofluorescence staining clearly showed that Cx43 protein accumulated in the cytoplasm of HCC827 and their GR cells. Conclusion The down-regulation of Cx43 expression in cytoplasm of HCC827 GR cells may contribute to the acquired gefitinib resistance in NSCLC cells by GJIC-independent activation of PI3 K/Akt signaling pathway.
