Thanks to such perspectives as technology continued acceptance and cross-organizational knowledge sharing,and review of existing literature and practice,the authors found the existing literature,both domestic and overseas,with the following shortcomings.In theory,there is little study on the telemedicine continued-acceptance behavior and cross-organizational knowledge sharing model; in methodology,there is little empirical study to build the telemedicine continued acceptance behavior model; in practice,there is little study on the telemedicine service management model in China's medical context.Based on such findings,the authors hold that subsequent studies may proceed individually and organizationally to study the continued acceptance model of telemedicine service users and cross-organizational coordination model of medical institutions.It also proposed countermeasures to optimize China's telemedicine sector.

Objective To investigate the effect of single bundle anatomic reconstruction of the anterior cruciate ligament (ACL) with the hamstring autograft through anteromedial approach. Methods From January 2012 to Jan-uary 2014, 39 patients with ACL tore had been treated with single bundle anatomic ACL reconstruction with the hamstring autograft. In this group, 20 males and 19 females, 16 cases of the left knee and 23 cases of the right knee;including 27 cases of sports injuries, 5 cases of traffic accident injury and 7 cases of fall injury.8 cases were acute injury the others were old injury. 22 cases were had the meniscus injury. All patients were treated with single bundle anatomic ACL reconstruction with the hamstring autograft. The femoral tunnel was establish through the anteromedial approach. The medial meniscus suture was performed in 10 cases, partial resection in 2 cases, lateral meniscus su-ture in 9 cases, partial resection in 1 cases. The hamstring autograft was fixed with the RIGFIX system in the femoral tunnel and the BIOSURE SYNC in the tibia tunnel. The Lysholm score was used to evaluate the recovery of knee function, and the MRI score was used to evaluate the integraty of the grafts. Results All cases were followedup for 15 to 39 months with an average of 21.5 months. All cases had no vascular nerve injury, joint stiffness, infec-tion and other complications. All cases had good stability after 1 year and recover to normal sports after six months and intense sports after half past a year postoperation. The anterior drawer test and the Pivot shift tests were negative in all patients. The Lacheman test wasⅠin 1 patient and others were negative. The mean Lysholm score was (93.85± 4.33) which significantly increased compared with preoperative scores which was (36.84 ± 5.60) after 15 months (P <0.05). The MRI showed good maturity and normal morphology of the ACL autograft, the MRI score was (9.80 ±1.70) after 1 year postoperation. Conclusion The arthroscopic single bundle individual anatomic ACL reconstruction with hamstring autograft through anteromedial approach is effective, simple to perform and gives a graft the same as nor-mal anatomy. The grafts revascularization is good and effectively restore the stability of the knee.

Objective:To explore the possibility of repairing partial nasal alar defects with individualized design of localized skin flaps.Methods:The clinical data of 38 patients with nasal alar region tumor from October 2015 to June 2019 in Dalian Municipal Central Hospital were retrospectively analyzed, including 5 cases with intradermal nevus, 8 cases with junction nevus, 21 cases with basal cell carcinoma, 3 cases with trichoepithelioma, and 1 case with nasal alar sulcus fistula combined with infection. Surgical treatment with local anaesthesia was applied, and intraoperative freezing pathology was used to confirm the diagnosis and determine the safe margin. There was no nasal alar cartilage infiltration in all patients. The defect areas after resection of nasal alar lesions ranged from 1.0 cm × 1.0 cm to 3.0 cm × 2.5 cm. Local skin flap was aesthetically designed in accordance with the location and size of the nasal alar defect to primarily repair the defect. Among them, 15 cases were repaired with pedicled nasolabial groove flap, 10 cases with modified rhomboid flap, 6 cases with rotatory nasolabial groove flap, 5 cases with V-Y push flap, and 2 cases with double lobe flap.Results:One case had blood transportation obstacle after operation caused by compression and bandaging, 1 case had postoperative infection. Healing of the two cases delayed after treatment, and other patients healed properly. All the flaps survived without facial deformity, and the cosmetic effect was good.Conclusions:The primary repair of the nasal alar defect needs to follow the aesthetic requirements of the nose and face, which varies with diseases and experience of doctors. Flap selection should be individualized to achieve both the purpose of repairing defects and beauty.

BACKGROUND:Silk fibroin/chitosan/nano hydroxyapatite (SF/CS/nHA) composite scaffold constructed in preliminary experiments has good physical and chemical properties.
OBJECTIVE:To study the capacity and mechanism of SF/CS/nHA composite scaffold for repair of rabbit radial bone defects.
METHODS:Thirty-six New Zealand white rabbits were selected to make animal models of right radial bone defects, and then randomly divided into SF/CS/nHA group, SF/CS group and blank control group. Blank control group had no treatment after modeling. X-ray radiography, gross observation and histopathological observation were performed at 4, 8, 12, 16 weeks postoperatively.
RESULTS AND CONCLUSION:Sixteen weeks after surgery, bone defects in the SF/CS/nHA group were completed replaced by normal bone tissue on X-ray images, and the bone marrow cavity showed complete recanalization with new bone formation;hematoxylin-eosin staining showed bone trabecula and many fusiform bone cells. In the SF/CS group, the bone mineral density in the defect area was slightly lower than that of the normal bone tissues, the bone marrow cavity was partly rehabilitated, and many chondrocytes were seen around bone cells that arranged irregularly with no bone trabecula or bone lamel a. In the blank control group, the images of bone calcification were consistent with normal bone tissues, and a closed bone ununion was formed at each end;hematoxylin-eosin staining showed that the blank control group was fil ed by fibrous connective tissue and a smal amount of bone-like tissues. SF/CS/nHA composite scaffold is better for repair of rabbit radial bone defects.
