Childhood asthma and obesity are significant public health problems all over the world.In the past decades,the prevalence of both diseases has increased considerably.Because both asthma and obesity appear to have their beginnings in early childhood,common exposures that predispose individuals to both conditions may explain how they are associated.These exposures include common genetic predictors,prenatal exposure to specific nutrients and overall maternal nutrition, colonization patterns of the neonatal and infant gut,birth weight and infant weight gain,and sedentary behaviors in early life.

Objective To explore the apoptosis of K562/G01 cells induced by triptolide through MDM2/p53 signaling pathway. Methods K562/G01 cell line was treated with different concentrations of triptolide. MTT was used to detect the cell proliferation inhibition rate. FCM was used to determine the apoptosis rate changes in 12 h and 24 h. The mRNA expression levels of bcr-abl, XIAP, MDM2, p53 were detected by real-time quantitative PCR. Results After treatment by 10, 20, 40, 80, 100 nmol/L TP in 12, 24, 48 h, the viability of K562/G01 cells was inhibited in time-dose dependence manner. K562/G01 cells was treated by 20 nmol/L, 40 nmol/L TP after 12 h, 24 h, the cell apoptosis rate was rising with drug concentration and time. The bcr-abl, XIAP, MDM2 mRNA expression was down-regulated and p53 mRNA expression was up-regulated by TP. Conclusion TP can inhibit the growth of K562/G01 cell line and induce apoptosis through XIAP-MDM2-p53 signaling pathway.

BACKGROUND: Microspheric injectable scaffold has a perspective in cartilage tissue engineering; however, it is still limited by in vivo hard forming and microsphere transmigration.OBJECTIVE: To investigate the feasibility of self-assembly scaffolds by attaching negatively charged calcium alginate microspheres and positively charged chitosan microspheres by electrostatic force. METHODS: The calcium alginate and chitosan microspheres were prepared by emulsion-internal gelation and spray drying technique, respectively. The characterizations of the microspheres were determined by means of scanning electron microscopy, optical microscopy and zeta potential analysis methods. Self-assembly scaffolds were fabricated by mixing the aqueous suspensions of the microspheres with oppositely charged surfaces. The phenomenon of electrostatic attachment was characterized by optical microscopy and scanning electron microscopy, and the elastic compress modulus of the scaffolds was also investigated.RESULTS AND CONCLUSION: The average diameter of the calcium alginate microspheres was 52.5 μm, and the chitosan one was 4.1 μm, respectively. The zeta-potential of the calcium alginate microspheres was 23.5 mv, and the chitosan one was +9.8 mv, respectively. The microspheres were spherical and smooth. The small size chitosan microspheres could attach to the surface of the calcium alginate microspheres and anchor the calcium alginate microspheres together. The elastic compress modulus increased with the increase of solid content of the microspheres, but decreased with the increase of the ionic strength. The elastic compress modulus increased firstly and then decreased with the increase of the mass ratio of m (CHI):m (ALG), and it showed the highest elastic compress modulus when m (CHI):m (ALG) was 2:1. The positively charged chitosan microspheres could attach to the negatively calcium alginate microspheres to form a self-assembly scaffold.

There was no statistically significant difference between the copper ion release amount of 99.99% and 99.95% purity copper wire (P > 0.05). The release of copper ion of the copper wire was far greater than that of the copper pipe in early stage (P < 0.01). The release amount decreased and stabilized at 56 day.

CONCLUSIONRelease characteristics of copper ion could effectively analysis by ICP. And in the same area, the release amount of copper ions of copper wire was greater than that of copper pipe.

Soil particles are very heterogeneous in microscopic scale, which is manifested the double-layer structure made of the soil organic matter and mineral matter. In this work, Fourier by transform infrared photoacoustic spectroscopy ( FTIR-PAS) combined with independent component analysis ( ICA) was utilized for in situ depth-profiling of the manmade complex film, in order to lay a foundation of in situ characterizing the heterogeneous soil organic-mineral complex. The complex film was composed of the PE preservative film and office adhesive tape. The moving velocity of infrared photoacoustic spectrometer was set to 0. 16 cm/s, 0. 32 cm/s and 0. 64 cm/s, respectively. Independent component analysis ( ICA ) was performed on the photoacoustic spectra of the heterogeneous complex film. Results showed that the depth-resolved information of the complex film could be derived by changing the moving velocity, and the estimated thickness of PE film was 5. 4-7. 6 μm, which was close to the actual thickness 7 ± 1 μm. Moverover, the spectral features of the polyethylene ( PE) preservative film and office adhesive tape were extracted from the photoacoustic spectra of the heterogeneous complex film by means of ICA. Depth profiling of complex film samples showed that FTIR-PAS could be used as a new analytical tool to study heterogeneous soils, especially soil organic-mineral complexes.
