Abstract： Background The number of chronic obstructive pulmonary disease （COPD） patients in China is huge，and respiratory rehabilitation training，as an important part of the management of COPD patients in the stabilization period，can effectively improve their lung function and quality of life，as well as reduce the burden on their families and society. Current data from Europe and the United States have shown that the implementation of respiratory rehabilitation under telemedicine management can improve the lung function and QOL of patients，however，there is a lack of relevant practice in China，especially in the west. Objective To assess the impact of respiratory rehabilitation training via telemedicine management in combination with conventional therapy on improving ventilatory capacity and lung function in elderly patients with moderateto-severe COPD. Methods This study was a prospective randomized controlled study，enrolling consecutive COPD patients who attended the Fourth Hospital of Sichuan Province and five joint community clinics from June 2021 to June 2022. The included patients were randomly divided into the experimental group and control group by simple randomized grouping method using random number table. The control group received traditional long-term regular inhalation bronchodilator and oral medication， and the experimental group was guided by telemedicine on the basis of the treatment plan of the control group. A six-month study was conducted on two groups of patients，lung function，Borg score，6MWT，and quality of life score（QOL score） were recorded at 1 month before and 1，3，6 months after intervention. Results The study subjects were divided into 72 cases in the control group and 73 cases in the experimental group，and there was no significant difference in gender，age and lung function at baseline［the forced expiratory volume in one second/predicted value ratio（FEV1%pred），and the ratio of the forced expiratory volume in one second to the forced vital capacity（FEV1/FVC）］ between the two groups（P>0.05）. There was an interaction between time and group for dyspnea and mood in FEV1%pred，FEV1/FVC，6MWT level and QOL score（P<0.05）. After 1，3， and 6 months of intervention，FEV1%pred，FEV1/FVC，6MWT，Borg score，and QOL score of the experimental group were better than those of the control group，and the difference was statistically significant（P<0.05）；FEV1%pred，FEV1/FVC， Borg score，6MWT，and QOL scores at 3 and 6 months post-intervention were better than those at 1 month post-intervention in the experimental group（P<0.05）. Conclusion The use of telemedicine technology for respiratory rehabilitation of elderly moderate-to-severe COPD patients in the stable stage can effectively improve the pulmonary function，quality of life and the quality of survival of this group of patients.

Abstract：中国南方一些少数民族地区民间“端午药市”流传至今，体现了民族医药的独具特色及其深远影响。为了解瑶族端午药市交易现状和发掘民族医药传统知识，采用民族植物学等方法对湖南省蓝山县端午药市进行调查，完成包括基原、地方名、药用部位、用途和用法、出现频度等内容的药用植物编目。结果表明：蓝山县端午药市药用植物种类丰富，收集并鉴定了共计103 科222 属262 种，药用植物种类广泛分布于各科和属中，其中种类较多的科有五加科（11 种）、茜草科（11 种）、菊科（11 种）、百合科（10 种）、唇形科（9 种）、蝶形花科（8 种）、芸香科（7 种）。药市药浴植物畅销且种类多样，达94 种，占总数35.9%，体现瑶族在治疗疾病上以预防保健为主的理念。经统计药市上均未被国家药典和地方标准收录的药用植物有131 种，占总数50.2%，成为发掘新药源、新用途的潜在资源。该研究还对端午药市售药者年龄进行调查，发现售药者的年龄主要集中在50～59 岁间，占总人数67%，40 岁以下的仅占总人数3%，可见民族药用传统知识的传承存在传承人老龄化、潜在传承人数量锐减的现象。该文还对药市交易药用植物的种类组成和民族药用特色进行了分析，探讨了端午药市对药用传统知识保护与传承的影响，并对蓝山端午药市的可持续发展提出了建议。

Abstract：冕环结构的准确识别和跟踪有利于更好地研究和分析冕环特征以及同耀斑爆发和日冕物质抛射之间的关系。提出基于相位一致性和方向滤波的冕环震荡识别和跟踪方法。识别过程如下:首先，使用相位一致性技术对太阳图像中的冕环特征进行识别;其次，对识别后的图像进行二值化处理;接着使用方向滤波去除非冕环的结构特征;然后，对其进行形态学处理;最后，再对识别结果进行二次曲线拟合。运用所提算法对2011年9月6日由太阳动力学观测站(Solar Dynamics Observatory, SDO)在Fe IX 17.1 nm波段观测到的冕环震荡进行了识别和跟踪，结果验证了所提算法的可行性和准确性。证明所提算法能被用于冕环特性以及震荡过程的研究和分析。
