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 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 .
