With the growing comprehensive national strength and international position,the international exchanges in medical health care field become actively and frequently,in which the medical associations play a proactive and facilitating role.The importance of foreign affairs of medical associations emerges.The management of foreign affairs is an important area of management.The foreign affairs must be in compliance with national policy to guide,regulate and dispose issues and problems.The management of foreign affairs of medical associations is one of the tasks of civil diplomacy and is also key component of civil diplomacy of Chinese characteristics which serves for national holistic diplomacy policy.The author is a project manager dealing with foreign affairs in Chinese Medical Association (CMA).Therefore,the author plans to analyze current international exchanges of CMA so as to explore certain enlightenments for peers.The paper is written based on international exchanges practice by CMA and analysis of typical cases,so as to raises some thoughts about how to improve the work of management of foreign affairs of medical associations.

Integrating Post-Abortion family planning services into existing abortion services in hospital settings in China (INPAC) Project under European Union Framework 7 is an international cooperative study underwent by 7 Sino-European research institutions and non-profit organizations.By learning experiences and integrating the methods of tree-like hierarchical management, whole process management and fine management, the Chinese Medical Association explored a characteristic management method of international cooperative study suitable for non-profit organization, which effectively facilitated project management and financial management and stimulated the disciplinary development and talents building.

To study the toxicity-decreasing and synergistic effect of intracellular and extracellular polysaccharides from Phellinus igniarius on S180 mice. The PIP and PIE were extracted from the products of liquid submerged fermentation of P. igniarius. Transplanting S180 mice tumor models were established so as to observe the changes in tumor inhibiting rate, indexes of the spleen and thymus, body weight, peripheral blood cells and IFN-gamma levels when CTX was used alone and when used in combination with the PIP and PIE from P. igniarius. The results indicate that the PIP and PIE from P. igniarius can increase the activity of body immunity, attenuate the toxicity of CTX as well, and improve the anti-tumor effects.

Objective:To study the association between apparent temperature (AT) and the incidence of hand,foot, and mouth disease (HFMD) and its spatial heterogeneity in 46 cities in Guangdong, Anhui and Jilin provinces, and provide scientific evidence for the early warning of HFMD.Methods:The data of HFMD incidence and meteorological factors from 2009 to 2018 in Guangdong province, 2009 to 2015 in Anhui province, and 2013 to 2018 in Jilin province were collected. Distributed lag non-linear models were constructed to investigate the association between AT and the incidence of HFMD in 46 cities from three provinces in China. Meta-analysis was used to pool the city-specific estimates, and Meta-regression was applied to analyze the factors that may cause spatial heterogeneity.Results:The relationship between daily AT and the incidence of HFMD in 46 cities appeared nonlinear. The association in Guangdong was similar to that in Jilin, and the risk of HFMD increased with the increase of AT. While the risk of HFMD in Anhui first increased with the increase of AT, and peaked at 18.1 ℃ and then went down. AT on different levels showed different lag impacts and the higher AT showed greater and longer lag impact. The spatial heterogeneity of associations may have been caused by latitude, longitude, average temperature, and average sunshine hours.Conclusions:AT is a comprehensive index to evaluate the association between temperature, relative humidity and wind speed and the incidence of HFMD. Higher AT may increase the risk of HFMD. The AT and HFMD relationship across spatial heterogeneity varies depending on geographic location and meteorological conditions.

Objective To review the patients with rheumatic tricuspid valve disease ( RTVD) who were confirmed in cardiac operation and underwent tricuspid valve repair ,and summarize two and three-dimensional echocardiography ( 2D-STE ,3D-STE) characteristics of RTVD ,and evaluate the surgical procedures and outcomes of RTVD . Methods Between December 2009 and December 2017 ,359 patients with rheumatic heart disease ( RHD) underwent left-sided valvular replacement were enrolled . During the operation , 56 patients with RTVD were confirmed . All patients underwent 2D-STE and 3D-STE preoperatively . The preoperative echo characteristics of RTVD and the procedure of tricuspid valvular repair were reviewed . The morphology and function of tricuspid valve were followed after operation . Results Fifteen patients with RTVD were diagnosed by transthoracic echocardiography( TTE) preoperatively .Eight patients were presented tricuspid stenosis . Tricuspid annulus diameter [ ( 40 .3 ± 5 .6 ) mm ] , tethering distance[(5.9±2.2)mm] ,andpulmonaryarterysystolicpressure[(46.3±15.9)mmHg(1mmHg=0.133 kPa) ] were measured by echocardiography ,preoperatively . Moderate and severe tricuspid regurgitation were presented in 32 patients( 57 .1％ ) . All patients underwent tricuspid valvular repair . During the mean follow-up (78 .9 months) ,tricuspid annulus diameter was reduced and tricuspid regurgitation was relieved . Recurrent tricuspid regurgitation occurred in 8 patients(14 .3％ ) . Conclusions Preoperatively 2D-STE and 3D-STE need to evaluate tricuspid valve very carefully . Compared with functional tricuspid regurgitation , RTVD has some characteristics ,including more serious tricuspid reflux grade ,higher tethering distance ,the mismatch between tricuspid reflux degree and tricuspid anmular diameter or pulmonary artery pressure . Tricuspid valve repair shows better early and mid-term outcomes .
