Senior Population’s Acceptance and Expectance of Wearable Medical Devices in China

The purpose of this paper is to investigate: 1. How well the senior population in China accept the wearable medical devices; 2. What kind of products the senior population in China would like to choose; 3. At what price the senior population are willing to pay. Collected information from secondary data resources to understand the wearable medical devices market in China and conducted online survey through professional survey software WenJuanXing to collect primary data from 217 elderlies (above 50 years old) in China. Based on the data collected by the online survey, half of the respondents are interested in using wearing medical devices. Top three concerns about the wearable medical devices are safety, veracity and reliability. About 56% of respondents are willing to pay no more than 600 RMB (about 90 USD) for the device itself. About 54% of respondents are willing to pay no more than 60 RMB / Month for the service (about 110 USD per year)

Observation on intravitreal injection of ranibizumab combined with laser photocoagulation for the treatment of macular edema in BRVO

AIM: To observe the safety and efficacy of intravitreal injection of ranibizumab combined with laser photocoagulation for the treatment of macular edema in branch retinal vein occlusion(BRVO).<p>METHODS: According to fundus fluorescein angiography(FFA), 30 eyes of 30 patients with BRVO were randomized into three groups: group 1(10 eyes)received grid laser treatment alone, group 2 received a single dose of intravitreal injection of ranibizumab(0.05mL/0.5mg)followed by grid laser treatment on 7d following injection, while group 3(10 eyes)received three loading doses of intravitreal ranibizumab with 0.05mL/0.5mg for three times. At 1mo interval, grid laser treatment was performed after 7d of the 1st injection. After 6mo follow-up, the best-corrected visual acuity and optical coherence tomography(OCT)and central macular thickness were observed. <p>RESULTS:After 6mo, the visual acuity of patients were improved significantly. There was an average increase of 11 letters, 17 letters and 18 letters in group 1, 2, and 3, respectively, with the average decrease in OCT being 208.7μm, 312.9μm and 326.8μm, respectively, in these groups. Gain in visual acuity more than 3 lines was 1 case(10%)in group 1. There were 3 cases(30%)in group 2 and 4 cases(40%)in group 3.<p>CONCLUSION:Combined therapy is better than laser therapy alone. Single dose of intravitreal ranibizumab with grid laser for macular edema in BRVO seems to be effective

3-Bromo­anilinium picrate

In the title compound, C6H7BrN+·C6H2N3O7 −, the O atoms of two of the nitro groups are disordered over two sites, the ratios of the refined occupancies being 0.72 (6):0.28 (6) and 0.74 (5):0.26 (5). In the crystal structure, the anions and cations are linked via inter­molecular N—H⋯O hydrogen bonds into chains along [100]. Further stabilization is provided by weak inter­molecular C—H⋯O hydrogen bonds
