ABSTRACT
Massive open online course (MOOC), as an online teaching mode, has attracted widespread attention in the education field. It realizes the integration of online teaching and learning in medical education and brings profound changes in concepts and methods of medical education. It has proposed a new development direction for modern medical education. The first Nuclear Medicine online MOOC resource is not only a supplement to direct face-to-face courses in a special period, but also a strong support for the realization of online and offline hybrid teaching, thereby promoting the " student-centered" undergraduates′ autonomous learning ability. The students can achieve the goal of the development of learning ability. Based on the results of applying the Nuclear Medicine MOOC to the teaching of undergraduates in multiple schools, this article further explains the obvious advantages of MOOC as an online teaching resource library for students′ knowledge internalization. The foundation of the new teaching method ensures the effective implementation of the above teaching methods and provides ideas for further deepening the reform of undergraduate medical education.
ABSTRACT
Objective@#To discuss the surgical technique of lateral unicondylar knee replacement (UKR) for patients with lateral compartment osteoarthritis and evaluate its recent clinical efficacy.@*Methods@#A retrospective analysis was conducted on 22 cases of lateral compartment osteoarthritis patients receiving lateral UKR at Orthopedic Department, Beijing Chao Yang Hospital, Capital Medical University from January 2016 to January 2019.There were 8 males (8 knees) and 14 females (14 knees), aged 65.7 years(range: 54 to 83 years).All patients completed preoperative imaging examination and excluded extra-articular deformity.Lateral parapelatellar approach was used for the operation and the tibial osteotomy was performed by extramedullary positioning.The residual cartilage of the external condyle was removed by pendulum saw to subchondral bone.Appropriate prosthesis were selected, and the tightness of the gap and the stability of the joints were repeatedly confirmed during the operation.The postoperative complications and the results of physical and imaging examinations were collected.The preoperative and postoperative Oxford knee Score (OKS) and knee society score (KSS) of patients were recorded and compared by paired t test.@*Results@#All patients were followed up for 24.6 months (range: 8 to 40 months).No complications such as incision exudation, skin necrosis and deep venous thrombosis of lower limbs were found after the operation.No cases of prosthesis loosening, excessive wear of pads, dislocation and postoperative infection were found at the last follow-up.The OKS decreased from 46.5±3.1 preoperative to 22.4±3.3 postoperative(t=13.4, P=0.00) and KSS improved from 69.5±8.7 preoperative to 90.2±7.4 postoperative (t=16.9, P=0.00) .@*Conclusions@#For the treatment of lateral compartment osteoarthritis, UKR has the advantages of rapid recovery of knee function, less complications and less trauma.The short-term efficacy is satisfactory, but the long-term efficacy remains to be observed.

ABSTRACT
Objective@#To evaluate clinical treatment efficacy of double-row fixation with bridging suture anchors for chronic, severe patellar tendinopathy.@*Methods@#A retrospective study of 18 patients suffered from severe patellar tendinopathy and underwent surgical treatment during January 2009 and June 2014 at Department of Orthopedic, Beijing Chao Yang Hospital, Capital Medical University was conducted. All patients had received conservative therapy for more than 6 months(range: 6-30 months) but the effect was unsatisfactory. There were 10 males (12 knees) and 8 females (12 knees)with age of 47.2 years(range: 32-63 years). Seven cases on the left and 17 cases on the right. The surgical treatment included a midline incision at patellar tendon, complete debridement, and double-row fixation with bridging suture anchors. Visual analogue scale(VAS), Lysholm score were collected preoperatively and postoperatively, and compared by paired-t test. The postoperative complications was recorded.@*Results@#All patients were followed up for 35.7 months (range:24-64 months) without any dropout.VAS decreased from 7.5±1.6 preoperative to 1.4±1.0 (t=4.45, P=0.00) postoperative, Lysholm score increased from 48.3±5.2 to 89.6±5.4 (t=-4.88,P=0.00).The Lysholm score was excellent in 3 cases and good in 15 cases.No patellar tendon rupture or suture fixation failure was recorded during the follow-up period.@*Conclusions@#The effect of double-row fixation with bridging suture anchors is satisfactory with few postoperative complications.It can not only improve clinical symptoms of patients, but also restore knee joint function.
