Objective To know the rural doctors' knowledge,belief and practice on iodine deficiency disorders(IDD),as well as their capability on health education communication in Ye County,Henan Province.Methods Semi-structured interviews were conducted among 50 rural doctors in Ye County,Henan Province.Topics covered include:sales of salt purchases,daily supervision and monitoring activities of salt,the health effects of salt,the situation of rural doctors trained,the situation of rural doctors participated in health education and related recommendations.Results ①Twenty-nine of the rural doctors knew exactly the advantage of salt iodization.②Thirty-nine of the rural doctors had taken part in the half quantitative detection of salt once or twice a year and 15 of them knew the supervision activities of salt industry department.③Forty-nine of the rural doctors believed salt iodization was beneficial to health and 48 of them were willing to participate in health education on IDD.④The major ways of their acquiring health knowledge were promotional materials [54.0％ (27/50)],TV [50.0％ (25/50)],and lecture/training [24.0％ (12/50)].⑤Thirty-seven of the rural doctors had taken part in health education on IDD.They were used to use booklets [68.0％ (34/50)],promotional slogan [36.0％ (18/50)],broadcast [24.0％ (12/50)],and doctor consultation [24.0％ (12/50)].⑥Twenty-eight of the rural doctors thought the current health education on IDD was better.They hoped to reduce the price of salt,strengthen supervision,receive more training and health education on IDD.Conclusions The rural doctors remain relatively lack of knowledge on IDD.Rural doctors have the initiative and responsibility to conduct health education on IDD,but their pattern is still a one-way propagation.

Objective To investigate the influence of mental intervention on the self-image of breast cancer patients.Methods Fifty patients with breast cancer who were hospitalized in our hospital from January to September,2015 were enrolled as the control group in the study,where routine nursing intervention,health education on disease related knowledge and psychological nursing were carried out.During October 2015 to June 2016,50 patients with breast cancer were enrolled as the observation group,where psychological awareness intervention was carried out apart from the routine nursing intervention.The self-image level of breast cancer patients from the two groups was evaluated by self-image questionnaire for breast cancer patients (BIBCQ).Result After intervention,the scores on self-image in the observation group were significantly higher than those in the control group (P＜0.05).Conclusion Mental intervention can improve the self-image of breast cancer patients and help improve their quality of life.

Caveolins are the major component proteins of the caveolae, and they are also the essential proteins to carry out the physiological functions of caveolae. Caveolins are expressed in smooth muscle cels, endothelial cels, and adipocytes. Caveolae are not only involved in the basic physiological processes, such as celular fat intake, endocytosis, and pinocytosis, but also play a very important role in cel signal transduction and transport and permeability of macromolecular substance. With the in-depth research on the molecular structure and biochemical function of caveolins, increasing studies have shown that caveolae and their main component caveolins play an important role in the pathophysiological process of cerebrovascular diseases. This article reviews the roles of caveolins in the blood-brain barrier destruction after cerebral ischemia.

Previous studies have shown that miRNAs participate in a wide range of biological functions and play important roles in various human diseases including cancer. We found miR-146b-5p significantly dysregulated in human pancreatic cancer cells by qRT-PCR. To demonstrate its function and regulation mechanism, we overexpressed miR-146-5p by transfecting the mimics. Our data showed that miR-146b-5p overexpression significantly reduced the abilities of migration and invasion of MIA PaCa-2 pancreatic cancer cells. Furthermore, we found that matrix metalloproteinase 16 (MMP16) was a downstream target of miR-146b-5p by dual-luciferase reporter assay. Altogether, our findings suggest that miR-146b-5p may be involved in pancreatic cancer cell migration and invasion by targeting MMP16, and miR-146b-5p may be a potential therapeutic target for the pancreatic cancer.
