[Evaluation on effectiveness of community-based comprehensive intervention and internet-based intervention for vaccination among patients with chronic diseases].

To evaluate the effectiveness of community-based comprehensive intervention and internet-based intervention on influenza and pneumococcal vaccination in patients with diabetes or chronic obstructive pulmonary disease (COPD) in communities. Before the onset of influenza in 2015 and 2016, five demonstration areas for comprehensive prevention and control of chronic diseases were selected in the study. Patients aged 35 years old and above with diabetes and COPD were selected from selected demonstration areas as study participants. Two communities were selected from each demonstration area and randomly divided into Group A with the community-based comprehensive intervention and Group B with the combination of community-based comprehensive intervention and internet-based intervention within 6 months. The differences of vaccination knowledge, vaccination intention and vaccination proportion in study participants between the two groups before and after interventions were analyzed and compared. A total of 15 226 patients were included in the study. After the intervention the increase in the vaccine knowledge score, vaccination intention and vaccination proportion of patients in the two groups were all higher than those before the intervention. After intervention, the increase of the median score of vaccine knowledge in group B (50.00 points) was higher than that in Group A (42.86 points). The increase of influenza vaccination intention in Group B (6.91%) was higher than that in Group A (4.16%). The increase of proportion of influenza vaccination in Group B (7.35%) was lower than that in Group A (16.61%). The increase of pneumococcal vaccination intention in Group B (7.90%) was lower than that in Group A (9.08%). The proportion of pneumococcal vaccination in Group B (3.37%) was lower than that in Group A (4.06%). Community-based comprehensive intervention could improve the level of vaccine knowledge, vaccination intention and vaccination proportion of patients in this study. Combined with community-based intervention, internet-based intervention could have a better effect on improving vaccine knowledge and influenza vaccination intention, but its impact on vaccination proportion needs to be further explored.

Downregulation of miR-193b contributes to enhance urokinase-type plasminogen activator (uPA) expression and tumor progression and invasion in human breast cancer.

Emerging evidence suggests the potential involvement of altered regulation of miRNAs in the pathogenesis of cancers, and these miRNAs are thought to be functional as tumor suppressors or oncogenes. Using miRNA arrays, we identified an miRNA differentially expressed between the MDA-MB-231 cell line and its highly metastatic variant. A bioinformatics search revealed a potential target site for miR-193b within the 3'UTR of uPA. Ectopic expression of miR-193b repressed the expression of sensor constructs harboring the 3'UTR of uPA in breast cancer cell lines. Anti-miR-193b treatment led to an increase of uPA protein and increased cell invasion in MDA-MB-231 cells. In contrast, overexpression of miR-193b significantly reduced uPA protein amounts and inhibited cell invasion in MDA-MB-231 and MDA-MB-435 cells. In an immunodeficient mouse model, miR-193b significantly inhibited the growth and dissemination of xenograft tumors. Immunohistochemical staining and real-time PCR assays showed that miR-193b was a negative regulator of the uPA gene in primary breast tumors. Our research reveals that miR-193b is closely associated with clinical metastasis and identifies miR-193b potentially targets uPA transcripts. Perturbation of the miRNA-mRNA pairing may have important roles in the initiation and development of breast cancer.
