Objective To prepare oxidized mesoporous carbon nanospheres and investigate potential application as drug delivery carriers for paclitaxel .Methods Physicochemical properties such as morphology ,diameter ,pore diameter and pore volume were characterized .Drug‐loading capacity was measured and drug release behavior in vitro was investigated by dialysis method .In vitro antitumour effect was evaluated by CCK‐8 methods .Results The synthesized oxidized mesoporous carbon nanospheres had an average diameter of 140 nm ,Zeta potential of -36 mV ,high specific surface area of 704.63 m2/g ,high drug‐loading capacity of 45 .6% .Conclusion Oxidized mesoporous carbon nanospheres have promising application in anti‐cancer drug delivery system .

Objective To research the epithelial-mesenchymal transition (EMT) effects of cuprous oxide nanoparticles (CONPs) on melanoma.Methods Cuprous oxide nanoparticles were prepared hydrothermally.The B16 cells were cultured with cuprous oxide nanoparticlesat different concentrations (5,25,50 μg/ml).The changes of the morphology of the B16 cell were observed under the inverted microscope.The effects of CONPs on B16 cell migration ability were detected through the Wound healing assay and the Transwell assay.Then cell immunofluorescence and western blotting were used to test the EMT related molecular markers, including E-cadherin, N-cadherin, Cytokeratin, and Vimentin.Results The synthesized cuprous oxide nanoparticles distribute uniformly with a diameter of 40 nm.Our study indicated that CONPs inhibited the EMT of B16 cell.A conversion process was discovered in this study.In B16 cells, CONPs inhibited B16 cell migration, promoted the expression of E-cadherin, Cytokeratin and Desmoplakin, while the expression of N-cadherin and Vimentin was repressed in protein level.Conclusion Cuprous oxide nanoparticles can significantly restrain the invasion and metastasis of melanoma cells and inhabit the EMT of B16 cells.

Objective: To investigate the incidence of human rhinovirus (HRV) infection in hospitalized patients in emergency department. Methods: A total of 94 emergency patients admitted to the emergency department from November to December of 2018 were enrolled in this study. The rhinovirus infection and related risk factors were analyzed. Results: HRV infection occurred in 17 out of 94 hospitalized patients in emergency department, the infection rate was 18.09%; Multiple HRV serotypes were prevalent from November to December of 2018, which were A9, A10, A16, A31, A73, B42 and C3. Elderly patients are at high risk of rhinovirus infection; Rhinovirus infection may increase the course of inpatients. Conclusions From November to December of 2018, multiple serotypes of HRV infections in the emergency department of Bengbu, Anhui, and HRV easily infected elderly inpatients.
