Objective:To analyze the research status and research hotspots of Taohe Chengqi Decoction.Methods:Research literature about Taohe Chengqi Decoction was retrieved from CNKI, VIP, Wanfang Data, Wanfang medonline, SinoMed from the establishment of the database to May 1, 2023, included peach pit gas soup research literature. NoteExpress 3.7.0.9258 software was used to organize the title list, and CiteSpace 6.2.R2 was used for visualization analysis on the author, research institution and key words.Results:A total of 957 articles were included. The journal with the most publications was New Traditional Chinese Medicine (35 articles). The main treatment diseases were diabetes, thoracolumbar fractures, constipation and other diseases. Authors with more publications were Xiong Manqi (19 articles), Li Saimei (18 articles), Wang Jun (15 articles), Zhu Zhangzhi (12 articles); The institutions with more publications were Guangzhou University of Chinese Medicine, the First Affiliated Hospital of Tianjin University of Traditional Chinese Medicine, Nanjing University of Chinese Medicine, Tianjin University of Traditional Chinese Medicine, Beijing University of Chinese Medicine, etc. The research mainly focused on the clinical application of TCM, animal experiments and other fields. Conclusions:The number of research literature about Taohe Chengqi Decoction is on the rise, and the treatment of diabetes attracts more attention. The research hotspot is the emerging technology in studying mechanism of Taohe Chengqi Decoction.

Objective: To explore the acute effect of air pollution on mortality for patients with cardio cerebral vascular disease and to provide the basis for disease prevention and control.
Methods: The Mortality for patients with cardio cerebral vascular disease from 2001-01 to 2009-12 was from Tianjin Centers for Disease Control and Prevention, the meteorological and air pollution data were from Tianjin meteorological bureau and Tianjin environmental monitoring station respectively. The Single and multiple generalized additive model (GAM) extended poisson regression analysis was performed to calculate the relationship between air pollution and cardio-cerebral vascular disease mortality by controlling the time trends, weather, the day of week and air population.
Results: Results: Single GAM analysis indicated that when the effect of SO2, NO2 and PM10 in the air reached the maximum in the day, the RR values for the mortality in patients with cardio-cerebral vascular disease increased 1.13%[95%CI (0.76-1.51)%], 0.78% [95%CI ( 0.41-1.15)%] and 0.61% [95%CI ( 0.51-0.71)%] respectively; when the average concentration of SO2, NO2 and PM10 increasing 10μg/m3 per day, after 0-5 days, the RR values for the mortality elevated 0.70% [95%CI (0.47-0.94)%], 0.51% [95%CI (0.27-0.74)%] and 0.16% [95%CI (0.06-0.27)%] respectively. Multiple GAM analysis presented that when SO2, NO2 and PM10 increasing 10 μg/m3 per day, the RR values for the mortality elevated 0.77% [95%CI (0.58-0.97)%], 0.41% [95%CI (0.05-0.78) %] and 0.38% [95%CI (0.12-0.64%)%] respectively.
Conclusion: The air pollution could increase the mortality risk in patients with cardio-cerebral vascular disease, it is necessary to establish the prevention system in order to decrease the mortality risk in those patients.
