Objective: This study explores the unmet psychosocial rehabilitation needs of cancer survivors.Methods: Sixty-eight cancer survivors from the Shanghai Cancer Rehabilitation Club in China participated in one of the eight focus groups. These were transcribed verbatim, coded using thematic analysis and analysed using NVivo 10.Results: Five main themes were identified: the need for (1) better information: Chinese cancer survivors find it difficult to sort and evaluate the overwhelming mass of information with which they are confronted; (2) psychological support: survivors fear cancer relapse and neighbours' discrimination against them; support from other cancer survivors can relieve the stress; (3) support for survivors' families: like the survivors, family members are under great but usually unacknowledged pressure; (4) improved health and medical services: community health service centres provide little medical, informational or psychological support for cancer survivors, who seek and expect more communication with doctors; and (5) assistance with the financial burden: costs of treatment and lack of adequate medical insurance cause substantial financial pressure for survivors.Conclusions: This study shows that, in addition to their illness, Chinese cancer survivors experience a range of stresses related to their financial circumstances, lack of reliable and summarised information, poor access to support and services (including for their families) and discrimination. Support from families seems to improve survivors' ability to cope. Cancer survivors (and their families) need an integrated package of support from their families, doctors and other service providers, hospitals and communities. These findings can inform approaches to continuing care for cancer survivors.

Matrix attachment regions (MARs) are cis-acting DNA elements that can increase transgene expression levels in a CHO cell expression system. To investigate the effects of MAR combinations on transgene expression and the underlying regulatory mechanisms, we generated constructs in which the enhanced green fluorescent protein (eGFP) gene flanked by different combinations of human β-interferon and β-globin MAR (iMAR and gMAR, respectively), which was driven by the cytomegalovirus (CMV) or simian virus (SV) 40 promoter. These were transfected into CHO-K1 cells, which were screened with geneticin; eGFP expression was detected by flow cytometry. The presence of MAR elements increased transfection efficiency and transient and stably expression of eGFP expression under both promoters; the level was higher when the two MARs differed (i.e., iMAR and gMAR) under the CMV but not the SV40 promoter. For the latter, two gMARs showed the highest activity. We also found that MARs increased the ratio of stably transfected positive colonies. These results indicate that combining the CMV promoter with two different MAR elements or the SV40 promoter with two gMARs is effective for inducing high expression level and stability of transgenes.

Diabetic nephropathy (DN) is one of the most common and serious chronic complications of diabetes mellitus, however, no efficient clinical drugs exist for the treatment of DN. We selected and synthesized several sesquiterpene lactones (SLs), and then used the MTT assay to detect rat mesangial cells (MCs) proliferation, ELISA to measure the expression level of monocyte chemoattractant protein-1 (MCP-1), transforming growth factor beta (TGF-β1) and fibronectin(FN), real-time fluorescent quantitative PCR analysis to measure the MCP-1 and TGF-β1 gene expression, western blot to detect the level of IκBα protein and EMSA to measure the activation of nuclear factor kappa B (NF-κB). We discovered that SLs, including parthenolide (PTL), micheliolide (MCL), arglabin, and isoalantolactone (IAL), as well as several synthetic analogs of these molecules, could effectively attenuate the high glucose-stimulated activation of NF-κB, the degradation of IκBα, and the expression of MCP-1, TGF-β1 and
