The paper analysed the scale,character,cooperation countries,funds and achievements of the traditional Chinese medicine (TCM) international projects between China Academy of Chinese Medical Sciences (CACMS) and Europe from 2007-2017.The results showed that there were 44 projects between CACMS and Europe;the number of Chinese medicine,clinical and basic research projects were 21,9 and 6 respectively;the number of projects between CACMS and Austria,and between CACMS and Gemany were 20 and 8 respectively;the funds from Ministry of Science and Technology and CACMS accounted for relatively high proportions.Trough these projects between CACMS and Europe,the TCM centers were established,the key technologies were introduced,and the professionals were trained.But there were still some questions such as the regional maldistribution of cooperation countries,few acupuncture research,and little project funds.

This paper summarizes and analyzes the current conditions of Tanzania traditional medicine practitioners, organization structure, herbal medicine resources, and the exported pharmaceutic products and related companies. The result shows that Tanzania government gradually pays the attention to the development of its own traditional medicine industry. Due to the current TCM cooperation dilemma with Tanzania, coping strategies should be adopted to provide certain references for the next stage of China-Tanzania TCM cooperation, such as adjusting the professional fields of dispatched experts, adjusting cooperative fields, including the export and investigation of TCM companies to Tanzania.

This paper analyzes and compares the development of Traditional Chinese Medicine (TCM) in Germany, France, the UK and Netherlands, considering the economic and social situation of countries. The SWOT strategic analysis is carried out on the basis of the proposittion of China-Europe cooperation in TCM, which encourage to carry out joint tackling of TCM for common diseases, jointly promoting the legislation with the guidance of the government and the participation of the public, speeding up the registration and listing of Chinese patent medicine with the focus on the Netherlands and the UK, and optimizing the perspective and strength of TCM publicity with the help of new media. In this way, TCM should be promoted in Europe.

Objective:To investigate the intervention effect and its mechanism of apocynin, an inhibitor of nicotinamide adenine dinucleotide phosphate (NADPH) oxidase (NOX) on silicosis induced by silica (SiO 2) in rats. Methods:In October 2021, 24 SPF SD male rats were divided into control group, silicosis model group and apocynin intervention group according to random number table method, with 8 rats in each group. SiO 2 was exposed by one-time intratracheal instillation. The rats in the apocynin intervention group were intraperitoneally injected with apocynin 50 mg/kg, 3 times a week, on the second day after treatment. The rats were sacrificed 28 days later, and lung coefficients were calculated after lung tissues were weighed. Hematoxylin-eosin staining and Masson staining were used to observe the lung histopathological changes in each group, respectively. The levels of NOX, reactive oxygen species (ROS), glutathione peroxidase (GSH-Px) and malondialdehyde (MDA) in lung tissue were detected. The expressions of interleukin-1 beta (IL-1β), interleukin-6 (IL-6) and tumor necrosis factor-alpha (TNF-α) were determined by Enzyme-Linked Immunosorbent Assay (ELISA). The level of hydroxyproline (HYP) was detected by alkaline hydrolysate. The expressions of transforming growth factor beta 1 (TGF-β1), E-cadherin (E-cad) and α-smooth muscle actin (α-SMA) in lung tissue were detected by Western blotting. Results:Compared with the control group, the body weight of silicosis model group was decreased, the lung tissue showed obvious inflammatory infiltration and fibrosis, and the levels of lung coefficient, IL-1β, IL-6, TNF-α and TGF-β1 were significantly increased ( P<0.05). Compared with the silicosis model group, the lung tissue injury in the apocynin intervention group was significantly improved, the lung coefficient, NOX, ROS, MDA, IL-1β, IL-6, TNF-α and TGF-β1 levels were decreased, and the activity of GSH-Px was increased ( P<0.05). Compared with the silicosis model group, the expressions of HYP and α-SMA were decreased and the level of E-cad was increased in the apocynin intervention group ( P<0.05) . Conclusion:Apocynin may alleviate SiO 2-induced fibrosis in silicosis rats by reducing oxidative stress, the release of inflammatory factors and inhibiting the process of epithelial-mesenchymal transition.
