AIM: To observe if there is a synergistical effect on induction of apoptosis when arsenic trioxide alone or combination with bortezomib in KM3 cells. METHODS: KM3 cells were treated with arsenic trioxide alone or combined with bortezomib, the numbers of viable cells were determined by trypan blue exclusion. Cell growth inhibition was examined by MTT method. The cells were simultaneously stained with annexin V-FITC and PI and apoptosis was determined by bivariate flow cytometry using a FACScan. Reverse trascriptional-PCR (RT-PCR) method was used to examine the change of p65 mRNA and Western blotting to measure the expression of protein p65, p-p65, caspase-3, -8, -9, and poly ADP-ribose polymerase (PARP). RESULTS: Arsenic trioxide inhibited the cell growth and induced apoptosis. The mechanism was responsible for the activation of caspase-mediated induction of apoptosis. A synergistic effect of combination with bortezomib on apoptosis was observed. CONCLUSION: Arsenic trioxide inhibits KM3 cell growth and induces apoptosis with a synergistical effect when cotreated with bortezomib.

Objectives To explore the correlation of level of serum 25-hydroxyvitamin D with pulmonary function in adult with asthma. Methods Patients were divided into Asthmatic group(n=62)and Control group (n=28). The Asthmatic group was further divided into Mild Group (n=6), Moderate Group (n=13) and Severe Group (n=43). Serum levels of 25-hy?droxyvitamin D [25(OH)D], denoted as 25(OH) Vit D was detected by ELISA. Pulmonary function indicators,including FVC (forced vital capacity) , FEV1 (forced expiratory volume in 1 second) , FEV1%predicted , and FEV1/FVC%were deter?mined by a pulmonary function testing device. General profiles such as medical history, age and height as well as serum VitD levels were compared between subgroups of the asthmatic groups and between two genders. Serum levels of 25 (OH) VitD were compared between asthmatic group and control group while its correlation with FEV1%predicted were calculated in all three sub asthmatic groups. Results There was no significant difference in medical history, age, height and the 25(OH) VitD levels between male and female participants. Serum 25(OH) Vit D level was significantly lower in the asthmatic patient group [(29.69±20.45) nmol/L] compared to that in control group [(75.16±4.06) nmol/L] (P<0.05). It was significantly lower in severe sub group than those in the mild and moderate sub groups. The differences were both statistically significant ( P<0.05). There were positive correlations between serum 25(OH) Vit D levels and FEV1%predicted ( P<0.05) in all sub asth?matic groups. Conclusion Vitamin D deficiency is highly prevalent in asthmatic patients, and there is a strong correlation between 25(OH) Vit D asthma severity as well as between lung function.

Adipose tissue is a readily available source of adult stem cells with multipotent properties suitable for tissue engineering and regenerative medical applications. Peptide hydrogel is a novel biomaterial which provides three-dimensional microenvironments for a variety of cells for tissue grafting. In this study, adipose-derived stem cells (ADSCs) were isolated from rats, seeded into the peptide hydrogel polymer scaffolds and cultured in Neurobasal (NB) media supplemented with B27, basic fibroblast growth factor (bFGF) and epidermal growth factor (EGF). Ten days after the culture, some cells were expanded into clonal populations in which the expression of both Nestin and Brdu was detected but only Brdu expression was detected in the cells that were not expanded into clonal populations. Our results suggested that ADSCs in peptide hydrogel polymer scaffolds can be induced to differentiate into cells capable of expressing the neuron-associated markers, self-renewal and self-propagation.
