Objective To discuss the defects of design and patients expected improvements of the screw-cap-type medicine box .Methods A total of 400 patients who had been using screw-cap-type medicine box were investigated with a questionnaire designed on the basis of open interview in 3 general hospitals in Fujian.Results Among the 400 patients, 75%of them believed screw-cap-type medicine box was inconvenient for its time-consuming , hard to control the dose , small label words on medicine bottle , poor for sealing and moisture-proofing, etc.A total of 267 patients (66.8%) hoped to use a new type of improved medicine box while most of them preferred a round medicine box with plastic manufacturing , convenient carry-over, easy opened, easy control the dose accurately and no more than 15 ml.Conclusions The screw-cap-type medicine box has many defects and requires to develop a new type of medicine box for patients with long -term use.

Objective: To examine the regulatory effect of bone marrow mesenchymal stem cells (BM-MSCs) on the polarization of bone marrow-derived macrophages, and to provide a theoretical support for the application of mesenchymal stem cells in the treatment of liver fibrosis. Methods: MSCs and macrophages were first isolated from the bone marrow of mice. Macrophages were polarized to M1 macrophages with lipopolysaccharide (LPS) and interferon-γ (IFN-γ), and to M2 macrophages with interleukin-4 (IL-4). The macrophages were then co-cultured with BM-MSCs in a Transwell for 24 h, and changes in the percentages of M1 and M2 macrophages were examined using flow cytometry. The mRNA levels of the M1 macrophage-associated cytokines, tumor necrosis factor-α (TNF-α) and interleukin-23a (IL-23a), and M2 macrophage-associated molecules, arginase-1 (Arg-1) and CD163, were measured by real-time quantitative PCR. The two samples were compared using the t test, and P < 0.05 was considered as statistically significant. Results: Flow cytometry showed that the percentage of M1 macrophages was significantly lower in the (macrophage + LPS + IFN-γ + BM-MSC) co-culture group than in the (macrophage + LPS + IFN-γ) group (62.5% ± 4.6% vs 86.6% ± 6.9%, t = 5.034, P = 0.0073). In addition, the relative mRNA expression of TNF-α and IL-23a was also significantly reduced in the co-culture group compared with those in the macrophage control group as measured by RT-qPCR (t = 11.57 and 10.57, respectively, P < 0.05). Compared with that in the macrophage control group, the percentage of M2 macrophages in the (macrophage+BM-MSC) co-culture group was significantly increased (89.5% ± 5.8% vs 70.1% ± 6.3%, t = 3.924, P = 0.0172), along with significantly elevated relative mRNA expression of Arg1 (14.35±1.05 vs 1.00±0.03, t = 21.96, P < 0.05) and CD163 (3.04 ± 0.27 vs 1.00 ± 0.03, t = 13.14, P < 0.05). Conclusion BM-MSCs can inhibit LPS + IFN-γ-induced polarization to M1 macrophages and promote polarization to M2 macrophages through the release of paracrine factors.
