The surveyof the situation of medical treatment for foreign students in Chongqing shows that there are certain problems in schools,hospitals and students etc.To strengthen the public health building,to improve conditions of medical services,to provide the necessary guide for medical treatment,and to enhance foreign students'self-adaptive capacities and so on may help solve these problems and improve the foreign students'health quality.

Objective: To summarize the clinical characteristics of coarctation of the aorta(CoA) associated with intracardiac anomalies in infants. Methods: The data from August 2009 to August 2017 of 86 infants who were diagnosed with CoA associated with intracardiac anomalies. Preoperative diagnosis, surgical findings and post-operation follow-up were analyzed retrospectively. There were 56 boys an 30 girls, aqed(95.1±78.0) days, weight(4.6±1.2) kg. Anatomical types included 37 cases of pre-ductal CoA, 44 cases of peri-ducutal CoA, and 5 cases of post-ductal CoA. And this group also included 73 infants complicating VSD, 59 infants complicating ASD, 2 infants complicating DORV, and 1 infant complicating TAPVC. Results: All of the included patients underwent single-stage repair of CoA associated with intracardiac anomalies. Mean operative time was(279.0±56.4) min, mean cardiopulmonary bypass time was(162.3±51.0) min, and mean aorta cross-clamp time was(74.7±25.2) min. Mean length of ICU stay and ventilation time were(7.4±4.7) days and(101.1±75.4) hours, respectively. The residual transcoarctation gradient before discharge was lower than pre-operative transcoarctation gradient significantly [(42.3±17.7) mmHg vs.(22.1±9.4)mmHg, P<0.001], and 7 early deaths were observed after surgery. The mean follow-up time of 79 hospital survivors was(31.0±27.4) months, and no late death was found. Transcoarctation gradient of hospital survivors in the last time follow-up was(21.2±11.0)mmHg. Transcoarctation gradient of 29 cases was higher than 20 mmHg, however, only 4 cases with significant clinical symptom of lower limbs retardation were recommended for ballon angioplasty consultant. The cumulative recoarctation-free survival in 2-year follow-up was 69.2%. Conclusion To avoid early second-stage operations, single-stage repair of CoA associated with intracardiac anomalies was effective and safe, and the outcomes of early to mid term follow-up were satisfactory.
