Objective To provide effective reference for quality analysis of the chemical composition and extraction of astragalus separation process by comparing the extract of astragalus and it’s IR spectra. Methods The saponins and flavonoids in astragalus were firstly extracted by the method of circumfluence with ethanol as solvent and the residue of ethanol-extraction was then used to extract polysaccharides by distilled water. Fourier transform infrared spectroscopy (IR) combined with second derivative infrared spectroscopy was applied to quickly identify astragalus herbs powder, water extraction of astragalus, astragalus alcohol extraction and water extraction of the residue of ethanol-extraction. Results The powder and 70% ethanol extract, 80% ethanol extract were around at 1 735 cm-1 (carbonyl stretching vibration absorption peak) has a weak, broad absorption, while the absorption peak was less obvious in boiling water extraction. So the maln components of astragalus water extraction are polysaccharides and also contaln a small amount of water-insoluble flavonoids. Alcohol extraction malnly contalns saponins and flavonoids, and flavonoid extract volume increases with increasing alcohol concentration in a certaln range.Conclusion This method can be a quick and easy identification for astragalus and it’s extraction for its chemical composition class, and provide the basis for further research quality.

Objective To summarize the clinical experience of one stage hybrid operation for aortic arch replacement and explore the indication. Methods From July,2009 to March,2010, 22 consecutive patients received one stage hybrid operation in our hybrid suite for aortic dissection or aortic aneurysm involving aortic arch. Two operative methods are used. (1)Bypass from ascending aorta to brachiocephalic arteries using midstemotomy and normothermia with antegrade aortic arch endovascular stented graft implantation. (2) Ascending aorta replacement and/or aortic valve replacement and/or coronary artery bypass grafting using midstemotomy and cardiopulmonary bypass with antegrade aortic arch endovascular stented graft implantation. Results All patients were technically successful. Angiography during the operation showed 100% patency of all the bypass grafts and no obvious translocation or endoleak of the stents. One patient in the first group died on sixth day after operation due to distal dissection rupture. There was one case of mediastinal lymph effusion in the second group and one case of death due to renal failure and respiratory failure 12 days after operation in the second group. The ICU stay and hospital stay were obviously shorter in hybrid open chest group than that in traditional open chest operation group(P <0.05). The blood product consumption and expenditure were also obviously less in hybrid open chest group than that in traditional open chest operation group (P <0.05). All the patients were followed up with a mean period of (14.45 ±2.33) months (range: 12 -20 months). All other patients were recovered with normal social life. CT showed neither endoleak nor translocation of the stented grafts. Faulse lumen closure rate at stented-graft segment is 100%. There was no obvious change of distal part of the dissection three months after operation except some thrombosis formation in some of the false lumen. Conclusion One stage hybrid operation for aortic arch replacement is safe and effective in shortening the duration of the operation and reducing the surgical trauma and risk of interval between procedures, shortening the hospital stay and reducing the blood product consumption compared with conventional operation with satisfactory early results. The midterm and long term results are still needed to be followed up.

10.The Wuhan model of visual health management for students: a referential framework for the public-school health system
Chinese Journal of School Health 2021;42(1):142-145
Abstract
According to the Healthy China Action Plan, Wuhan gives full play to the role of preventing and controlling student myopia by promoting student health. The primary focus is placed on education in schools, and Wuhan has integrated educational resources to develop a multi-level myopia prevention and control system and service network for school students. The network contains educational adminstrative, schools, families, and professional technical service organizations. By integrating multiple disciplines, Wuhan has built a comprehensive vision health management service system for all students. The Internet and cloud intelligent monitoring facilitated the establishment of a smart vision health management platform for students, which thoroughly and efficiently implemented myopia prevention and control to safeguard students visual health by engaging in education, monitoring, and supervision. The prevention and control of student myopia is a breakthrough for comprehensive healthy development of students. A comparison of the standard myopia rate in Wuhan in 2019 and 2018 revealed that the standard myopia rate at different learning stages of primary school, junior high school, and high school dropped by 3.31, 2.50, and 2.26 percentage points, respectively, and the rate of myopia in primary school was significantly lower than the national level. Post-epidemic surveys showed that the compliance rate and the awareness rate of the visual environment and visual behaviors of primary and secondary school students in Wuhan reached more than 80%, and prevalence of newly onset myopia or decreased vision was 30%, which was lower than the national average. The "Wuhan Model" provides an important referential framework for public health services for school students.
