Tiepishihu(Dendrobii officinalis Caulis)is a medicinal and food source herbal medicine with the effect of benefiting stomach and promoting fluid,nourishing Yin and clearing heat.It has rich chemical components and pharmacological activities,with anti-inflammatory,anti-bacterial,anti-oxidation,anti-tumor,immunomodulatory,blood press regulation,hypoglycemic effects.It is not only used as medicinal food and health care products,but also widely used in medicine,such as Shihu Yeguang Wan,Compound fresh dendrobium granules and other drugs,with high medicinal and economic value.This paper summarized the resource distribution,chemical composition,pharmacological activities,and medicine and food of Dendrobii officinalis Caulis,and analyzed its application status,laying a theoretical foundation for the sustainable development,medicinal and food homologous development and comprehensive utilization of Dendrobii officinalis Caulis.

Objective:To provide data support for optimizing aeromedical support to transporter flying personnel by comparing and analyzing the composition and variation of the medical grounding disease spectrum of them.Methods:The health profile data of transporter flying personnel who were grounded by the assessment in Air Force Medical Center from January 1, 2003, to December 31, 2020 were collected. They were grouped by grounded year (2003—2008, 2009—2014 and 2015—2020) and by post (pilot and air combat personnel). The age at the time of grounding, flying hours and grounding disease spectrum were statistically analyzed.Results:A total of 186 transporter flying personnel were enrolled, including 135 pilots (72.58%) and 51 air combat personnel (27.42%). The median grounding age of pilots was 34.0 (31.5, 39.0) years old, and the median grounding age of air combat crew was 43.0 (41.0, 46.0) years old. The top 4 system diseases in all flight grounding personnel were neurological diseases (21.51%), mental and psychiatric disorders (16.67%), cardiovascular system diseases (13.98%) and motion system diseases (10.75%). The difference in the component ratio of grounding diseases between the pilots and air combat personnel was significant ( P=0.039), and the grounding ratio of digestive system diseases in pilots was lower than that of air combat personnel ( χ2=5.40, P=0.020). The grounding ratio of motion system diseases in 2009—2014 group was lower than that of 2003—2009 group ( χ2=6.70, P=0.010). The grounding ratios of mental and psychiatric disorders in 2009—2014 and 2015—2020 group were higher than those of 2003—2008 group, with significant differences ( χ2=8.80, 7.33, P=0.005, 0.007). There were 76 types of diseases that caused transporter flying personnel grounding, and the top 3 diseases were hypertension, vascular headaches and lumbar disc herniation. Conclusions:The neurological diseases, mental and psychiatric disorders, cardiovascular system diseases and motion system diseases contribute most to the grounding of transporter flying personnel while the neurological diseases and mental and psychiatric disorders have resulted more and more groundings. As the higher flying training strength and time endurance required, the further disease spectrum analysis, as well as the corresponding prevention and treatment should be strengthened.
