Objective To provide reference for promoting the development of health information technologies by sur-veying the present situation of using health information technologies in residents of Beijing. Methods The present situation of using health information technologies in residents of Beijing was investigated using self-designed ques-tionnaires. A total of 584 valid questionnaires were returned. Results Of the 584 visited residents of Beijing, 67. 3%searched the online health information, 47. 6% considered that the online health information was reliable, 49. 5%had their appointment with a doctor, 485% used APP to search health information, 67. 0% believed that such a software was useful in seeking for doctors and drugs, 71. 4% showed their wishes of online shopping prescription drugs, and 75. 7% were ready to visit online hospitals. Conclusion The rate of searching online health information is rather high with a low reliability in the residents. The trend to have an appointment with a doctor is good in the residents. The APP has a great potential in searching online health information. The acceptability of online shop-ping prescription drugs and visiting online hospitals is high.

Objective To observe the role of intermediate conductance calcium?activated potassium channels (KCa3.1) in alkalinization and β?glycerophosphate induced vascular calcification. Methods Vascular smooth muscle cells (VSMCs) and aortic rings were obtained from rat thoracic aorta, and then randomly divided into control group (pH was provided into 7.4, 8.0), high phosphorus groups (pH was provided into 7.4, 7.7 and 8.0, VSMCs in three groups were treated with 10 mmol/L β?glycerophosphate; HCl and NaHCO3 were used to adjust the pH) and TRAM?34 group (20 nmol/L was added into pH8.0 high phosphorus dulbecco's modified eagle's medium). Calcium deposition and alkaline phosphatase (ALP) activity were measured by Alizarin red staining, calcium content and enzyme linked immunosorbent assay after cells were simulated for 12 days. Intracellular free Ca2 + was measured by ELISA. The expression of KCa3.1, runt?related transcription factor 2 (Runx2) were detected by RT?PCR and Western blotting 4 days after cells were stimulated. Calcium deposition was measured by von Kossa staining and calcium content after aortic rings were cultured for 12 days. The expressions of KCa3.1 and Runx2 were detected by immunohistochemistry after aortic rings were cultured for 4 days. Results Compared with control group, calcification in VSMCs and aortic rings were significantly increased in high phosphorus group (P<0.05) while decreased in TRAM?34 group (P<0.05). Compared with control group, the expressions of KCa3.1, Runx2 and the activity of ALP in high phosphorus groups were increased (P<0.05) while decreased in TRAM?34 group (P<0.05). Besides, expressions of Runx2 and KCa3.1 were augmented as the pH was higher (P<0.05). The expression of Runx2 in aortic rings was the same situation. Besides, the Ca2+ influx was blocked by TRAM?34 (P<0.05). Conclusions Alkalinization contributes to β?glycerophosphate induced VSMCs calcification through increase of Ca2 + influx, up?regulation of KCa3.1 and promotion of osteogenic/chondrogenic differentiation.

In the "Tutorial for outline of the healthy China 2030 plan", biomedicine was listed as a key planning and development area. Shanghai government also lists biomedicine as an emerging pillar industry. The rapid development of biomedicine industry put higher requirement for talents. Taking the idea of cross integration, mutually beneficial development, inheritance and innovation, the School of Biotechnology of East China University of Science and Technology organically integrates bioengineering and pharmaceutical majors to develop a new undergraduate engineering program of biomedicine, which specially reforms the talent training practice from the aspects of developing a "trinity teaching" standard system, a "three integration, three convergence" curriculum system, and a "three comprehensive education" innovative talent training system. We put forward the trinity of "value guidance, knowledge system, technology and non-technical core competence literacy" to foster emerging biomedicine engineering talents, and developed a comprehensive innovative talents training mode featured by "covering class-in and class-out, covering every student, and covering ideology and curriculum". Moreover, we established effective connections between courses and training goals, between general education courses and professional courses, and between top-notch talent training systems and training programs. Based on the achievements of teaching reform of the emerging engineering program "intelligent bio-manufacturing", the experience we obtained may provide ideas for development of the first-class bioengineering major in China.
