Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.

With the aging population in China,health issues among the elderly are becoming increasingly prominent,leading to a rapidly growing demand for health interventions for the elderly.Exergames are one of the important emerging methods in the field of health interventions for the elderly,widely used and yielding positive results.While research on exergames is well-established abroad,it is still in its infancy in China,lacking reports on the types,interaction forms,intervention content,application status,and effectiveness of exergames.Exergames are suitable for widespread use among the elderly in China,and there is a need to accelerate the development and application of exergames in the field of health interventions for the elderly in China.

Engaging in physical activity and exercise is one of the important ways for health promotion.However,older adults are often physically inactive or have a sedentary lifestyle and have poor compliance with physical activity.Exergaming program with their unique advantages could make physical activity a more joyful experience and motivate older adults to participate in physical activity.Promoting older adults'health through engagement in exergaming programs is still in the early stage,and still faces many challenges.Analyzing the challenges and difficulties faced by exergaming program for older adults and exploring in-depth strategies to promote the implementation of exergaming program for older adults are of great significance for the design and implementation of sports games for older adults.

OBJECTIVE： To establish a fluorescence identification method of the microscopic characteristics for Plantagin Semen and its adulterants， and to provide technical support for the market supervision and inspection of TCM decoction pieces. METHODS： Under visible and ultraviolet light， comparative study and identification of the Plantagin Semen （seeds of Platago asiatica L. and Platago depressa Willd.） and its adulterants as seeds of Platago major L.， fruits of Schizonepeta tenuifolia Briq.， seeds of Codonopsis pilosula （Franch.） Nannf， seeds （peeled） of Kochia scoparia （L.） Schrad.， fruits of Bupleurum chinense DC. were carried out by means of stereoscopic fluorescence microscopy from aspects of overall surface characteristics， umbilicus characteristics and section characteristics. RESULTS： Under visible light， the surface texture of Plantagin Semen was wavy stripe or fine wrinkle， while the adulterants were wavy stripe， longitudinal edge or texture was not obvious. The umbilicus of Plantagin Semen was located in the center of the ventral surface， while that of adulterants were located at one end except for P. major. In the section of Plantagin Semen， there were obvious direct embryos， in which the adulterants were small or circular embryos except for P. major. Under ultraviolet light， P. asiatica had obvious wavy stripes in surface， orange and light blue-green fluorescence； P. depressa had grid-shaped wrinkles and gray-blue and gray-brown fluorescence； the umbilical fluorescence of Plantagin Semen was strong， and the fluorescence of the adulterants was weak except for S. tenuifolia. There were obvious differences in fluorescence color， embryo size and distribution between the section of Plantagin Semen and adulterants. CONCLUSIONS： The stereoscopic fluorescence microscopy is effect and accurate for the identification of Plantagin Semen.
