Technological improvement for microorgnism isolation is important since isolation provides substantial materials for the exploitation of new microbial resources. In this study, a new approach, dispersion and differential cetrifugation (DDC), was applied in the isolation of acidophilic and acidoduric streptomycetes from 12 acid soil samples. Contrast with traditional method, the new approach yielded satisfying results with 2 - 20 times isolation efficiency and good selectivity. 45 representatives out of 249 streptomycetes isolates, which belonged to 12 color groups, showed morphology and cell wall type consistent with streptomycetes. The optimum pH range for their growth were between pH 4.5 - 5.5. It is proved that we succeeded in the rare-streptomycetes isolation using DDC approach.

Background and purpose:Chemotherapy plays an important role in the treatment of breast carcinoma by inhibiting the tumor growth and inducing the apoptosis.MAPK transduction pathway is closely related to proliferation and apoptosis of varieties of tumor cells,inhibition of MAPK pathway may increase the efficiency and decrease the toxicity of chemotherapy.Our study was to investigate the effect of MEK inhibitor PD98059 in response of breast cancer cell lines to Epirubicin.Methods:Human breast cancer cell lines MCF-7 and MCF-7/ADR were used as cell models.Epirubicin(EADM),PD98059(inhibitor of MAPK Kinase-MEK),or EADM+PD98059 was added into the culture medium,the expression of MEK2 and p-ERK were measured by Western blot,the growth of the two cell lines were measured by MTT.Results:ERK activity was elevated in MCF-7 after the treatment of EADM,the cells were more sensitive to EADM if combined with PD98059,while in MCF-7/ADR,ERK activity kept unchanged after EADM treatment,and PD98059 has no effect on the sensitivity of cells to EADM.Conclusion:MAPK signal transduction may be activated in some cells treated by EADM,adding inhibitor of MAPK signal transduction could improve the sensitivity of the cells to EADM.

Objective To analyze the relationship between body weight index (BMI) during the different pregnant weeks and the birth weight of newborns. Methods One hundred pregnant women and newborns were selected. BMI in every month during the pregnancy period, birth weight and height were observed and recorded. Then the relationship between BMI of pregnant women and birth weight of newborns was analyzed using Peas,son correlation coefficient. Results The correlation between BMI of pregnancy from the fifth month to the ninth month and the birth weight of newborns had significantly statistical meaning, especially the correlation between BMI of the fifth, the sixth and the eighth months and the birth weight of newborns were more obvious, each showing a positive correlation. Conclusions The higher the BMI of pregnant women, the higher the birth weight of newborns. Therefore the pertinent diet guidance should be given to the pregnant women in the middle to late stages of pregnancy according to the pregnant women's BMI, in order to reduce the incidence of enormous infants and premature infants.

Objective To investigate primipara' s fatigue status during pregnancy and the major related factors, provide basis for relevant intervention measures. Methods A total of 150 primiparas from a top-notched hospital in Beijing were investigated by using General Fatigue Self-assessment Scale (FSAS) ,Self-Efficacy Scale (GSES), Trait Coping Style Questionnaire (TCSQ) and Pregnancy Pressure Scale (PPS). Results Primipara's fatigue status was at a mild level, and could be relieved by sleep or rest; Age, gestational age and weight gain during pregnancy had different degrees of relevance with the score of FSAS( P <0. 05 ) ; Primipara' s fatigue was negatively relate to the general self-efficacy ( P <0. 05 ) ; Primipara' s fatigue was positively relate to positive coping,pregnancy pressure(P <0. 05 ). Conclusions The health education and pregnancy counseling for the primipara should be strengthened. And we should pay attention to primipara with fast weight gain, old gestational age and pregnancy complications. Further more, primipara should be encouraged to adopt positive coping, cultivate self-efficacy and reduce pregnancy stress by using early period intervention, which could help to reduce fatigue during pregnancy.

By inoculation of blood samples in DF-1 (C/E) cell culture, an exogenous avian leukosis virus (ALV) strain SDAU09C2 was isolated from a breeder farm of Chinese native breed "Luhua" in Shandong province. Comparisons of the amino acid sequence of env gene gp85 from the isolate with those from other ALV reference strains of different subgroups indicated that SDAU09C2 had the highest gp85 identity to two reference strains of subgroup B of 92.5%. Its gp85 identity to other chicken ALV subgroups A, C, D, E was in the range of 73.2%-87.9%. The identity to subgroup J was only 30.3%-32.4%. This is the first report on isolation and identification of ALV-B and its gp85 from Chinese native breed chickens.

The relationship between tyrosine phosphorylation (TP) and protein expression of insulin receptor (InsR) and insulin resistance (IR) in patients with gestational diabetes mellitus (GDM) was investigated. The InsR expression and TP in skeleton muscle tissue were determined by Western blotting and immunoprecipitation in women with GDM (GDM group, n=22), normal pregnant women (normal pregnancy group, n=22) and normal non-pregnant women (normal non-pregnant group, n=13). Fasting plasma glucose (FPG) and fasting insulin (FINS) were measured by oxidase assay and immunoradioassay. The results showed that the levels of FPG (5.61±0.78 mmol/L), FINS (15.42±5.13 mU/L) and Homeostasis model assessment-IR (HOMA-IR) (1.21±0.52) in GDM group were significantly higher than those in normal pregnancy group (4.43±0.46 mmol/L, 10.56±3.07 mU/L and 0.80±0.31 respectively) (P<0.01). The levels of FINS and HOMA-IR in normal pregnancy group were significantly higher than those in normal non-pregnant group (7.56±2.31 mU/L and 0.47±0.26 respectively) (P<0.01). There was no significant difference in the InsR expression level among the three groups (P>0.05). TP of InsR with insulin stimulation was significantly decreased in GDM group (0.20±0.05) as compared with normal pregnancy group (0.26±0.06) (P<0.01). TP of InsR with insulin stimulation in normal pregnancy group was lower than that in normal non-pregnant group (0.31±0.06) (P<0.01). TP of InsR with insulin stimulation was negatively related with HOMA-IR in GDM group (r=-0.525, P<0.01). There was no correlation between the protein expression of InsR and HOMA-IR in GDM group (r=-0.236, P>0.05). It was suggested that there is no significant correlation between the protein expression of InsR in skeletal muscle and IR in GDM, but changes in TP of InsR are associated with IR in GDM.

DNA microarrays have been acknowledged to represent a promising approach for the detection of viral pathogens. However, the probes designed for current arrays could cover only part of the given viral variants, that could result in false-negative or ambiguous data. If all the variants are to be covered, the requirement for more probes would render much higher spot density and thus higher cost of the arrays. Here we have developed a new strategy for oligonucleotide probe design. Using type I human immunodeficiency virus (HIV-1) tat gene as an example, we designed the array probes and validated the optimized parameters in silico. Results show that the oligo number is significantly reduced comparing with the existing methods, while specificity and hybridization efficiency remain intact. The adoption of this method in reducing the oligo numbers could increase the detection capacity for DNA microarrays, and would significantly lower the manufacturing cost for making array chips.
