ABSTRACT
Objective To reveal the biomechanical mechanism of suspension exercise therapy (SET) for treating cervical spondylosis. Methods From August 2015 to December 2016, 72 patients with cervical spondylosis were divided into experimental group (SET treatment group) and control group (traction treatment group) based on simple random sampling methods. For experimental group: 9 males and 27 females, the average age (45.19±10.09) years old, the average disease course (24.94±18.07) months. For control group: 11 males and 25 females, the average age (44.08±8.88) years old, the average disease course (22.17±14.96) months. The mechanical properties of neck muscles before treatment and at the end of disease course were tested by Biodex Ⅲ Isokinetic Testing System. Results Before treatment, there were no significant differences in the peak torque (PT), average power (AP), peak torque of flexor/extensor peak torque ratio (F/E) for both groups; after treatment, PT, AP, F/E in experimental group was improved compared with those in control group (P<0.05). Significant differences in PT, AP, F/E were found for experimental group before and after SET treatment(P<0.05). There were no significant differences in visual analogue scale (VAS) of neck pain for both groups before treatment (P＞0.05)，while the VAS of experimental group was better than that of control group(P<0.05). Significant differences in the VAS were found for experimental group before and after SET treatment(P<0.05). Conclusion sSET can improve the contraction forces and work efficiency of neck muscles for patients with cervical spondylosis, as well as the coordination ability of flexors and extensors muscles, which will contribute to restoring biomechanical properties of the patients with cervical spodylosis.

ABSTRACT
OBJECTIVE: To investigate the application of the retroperitoneal approach in aortic surgery. METHODS: We collected and analyzed data of 7 patients in Macau who presented with aortic diseases from 2007 to 2008 and were treated with aorta repair through retroperitoneal approach. Demographic features as well as intraoperative and postoperative data were analyzed. One case of thoracoabdominal aneurysm and 4 cases of abdominal aneurysm received artificial graft, among which hybrid iliac artery reconstruction with Zenith stent covering the ostium of the left subclavian artery was performed in 2 cases of infrarenal abdominal aneurysm. Aortic-iliac artery bypass was performed in 2 cases of aortoiliac occlusion. RESULTS: No operative or early postoperative death was observed. No perioperative intestinal adhesion or ureteral obstruction was found. One case reported delayed paraplegia and graft infection as postoperative complications. The complications were partially removed 3 months later after rehabilitation. CONCLUSION: Retroperitoneal approach is a safe and feasible technique, which associated with a low incidence of postoperative pulmonary complications.
