Objective To investigate the reliability of the morphologic measure of the iliotibial band (ITB) with musculoskeletal ultrasound imaging. Methods 20 healthy young subjects were measured with the musculoskeletal ultrasound imaging of the thickness of bilateral ITB at the levels of the femoral condyle by 2 testers, and one of the testers measured again 3-5 days later. The intraclass correlation coefficient (ICC) and minimum detectable change (MDC) were calculated, and the thickness of ITB in both sides was compared. Results The ICC of test-retest was 0.89 (R) and 0.85 (L), and it was 0.82 (R) and 0.84 (L) of inter-testers. The MDC was 0.41-0.51 mm. There was no significant different between right and left sides for the ITB thickness among healthy subjects (P=0.97). Conclusion Musculoskeletal ultrasound imaging is a feasible and reliable to measure the ITB thickness among young healthy subjects.

Objective To apply the WeChat in family rehabilitation after anterior cruciate ligament (ACL) reconstruction. Methods 126 patients accepted ACL reconstruction using quadrupled semitendinosus and gracilis tendons were divided into observation group (n=69) and control group (n=57). The control group received conventional rehabilitation program, and the observation group joined the WeChat group. They were assessed with knee range of motion (ROM), knee stability test, thigh perimeter, Lysholm score and the International Knee Documentation Committee (IKDC) score 3 and 6 months after operation. Results There was a significant difference between groups in ROM of knee flexion (P<0.05) 3 and 6 months after operation, but not in ROM of knee extension (P>0.05). There was no significant difference in thigh perimeter 3 months after operation, but it was significant 6 months after operation. There was significant difference in Lysholm score and IKDC score (P<0.05), but not in the joint stability (P>0.05). Conclusion Direction of rehabilitation with the WeChat Group can significantly improve the compliance, accelerate the rehabilitation process and reduce complications in patients after ACL reconstruction.

Traditional Chinese medicine (TCM) colleges and universities are important positions for inheriting and innovating the TCM culture. Exploring the innovation of teaching modes of ideological and political courses in TCM colleges and universities is a hot topic in current researches on education and teaching reform. There are some problems in the characteristic construction of ideological and political courses in TCM colleges and universities, such as insufficient effective integration of TCM culture, incomplete integrated design, and lack of supervision and evaluation system. In practical exploration, the "11432" teaching mode of ideological and political course based on the cultural characteristics of TCM has been formed. It is guided by "two major goals" and "three requirements", and organically integrates the TCM culture into the teaching of ideological and political course according to the principle of gradual progress. It takes the "Four Adherences" as its practice practical focus, and strives to create a "student-centered" classroom teaching mode. What’s more, it focuses on promoting the organic integration of TCM culture and ideological and political courses from the "five dimensions" in accordance with the fundamental task of "fostering virtue through education" and the requirements for talent training in TCM colleges and universities.
