Knee arthroscopy-assisted ambulatory surgery:Practice and considerations / 医学研究生学报

Objective Ambulatory surgery(AS),with its simple procedures and efficient utilization of resources,is an ef-fective means of improving medical efficiency.The aim of this study was to improve the daily procedures of AS by analyzing the perform-ance and results of knee arthroscopy-assisted AS. Methods This study included 188 cases of knee arthroscopic surgery performed from March to August 2017,97 of them treated in the Ambulatory Surgery Center(group A)and the other 91 in the conventional ward (group B). We compared the average hospital stay,hospitalization expenses,and postoperative complications between the two groups of patients. Results Compared with group B,group A showed a significantly shorter hospital stay([95.0±41.3]vs[25.5±0.8]h, P<0.05)and lower hospitalization expenses([28 699.6±11331.1]vs[22231.7±7152.2]RMB,P<0.05). No statistically significant difference was observed in the incidence rate of postoperative complications at 1 and 3 days after surgery,1 case of bleeding in group A and 1 case of leg swelling in group B. Conclusion Ambulatory surgery in our hospital needs to be further improved on the basis of accelerated rehabilitation surgery as the core concept,precision medicine as the approach,and individualized treatment as the goal.

Tracheal reconstruction with memory alloy prosthesis coated with collagen / 中国医疗器械杂志

<p><b>OBJECTIVE</b>To investigate the feasibility of tracheal reconstruction with a prosthesis made of memory alloy coated with collagen sponge in mongrel dogs.</p><p><b>METHOD</b>The basic skeleton of the prosthesis was knitted with Ni-Ti memory alloy wires. The tubular mesh was sealed with polyurethane membrane and then inner and external walls of the lumen were coated with collagen sponge. Cervical trachea segmental reconstruction was performed in 8 mongrel dogs with these prostheses. The efficacy of the implanted prostheses were periodically evaluated after operation using x-ray, tracheoscopy and specimen microscope examinations.</p><p><b>RESULTS</b>One dog died of prosthesis dislocation 10 days after operation, another was killed 45 days later because of anastomotic stenosis. 6 dogs survived more than 90 days and the longest one lived for 150 days. Its implanted prosthesis was completely incorporated with the recipient tissue, where re-epithelialization occluded on anastomotic sites. The tracheal lumen was patent.</p><p><b>CONCLUSION</b>This memory alloy tracheal prosthesis has been proved useful for reconstruction of large, circumferential tracheal defects, although its long-term safety and efficiency need to be confirmed.</p>

Effect of Transcutaneous Electric Nerve Stimulation and Physical Therapy on Shoulder Pain after Stroke / 中国康复理论与实践

@#ObjectiveTo observe the effect of transcutaneous electric nerve stimulation (TENS) and physical therapy on shoulder pain after stroke. Methods60 patients of shoulder pain after stroke were randomly divided into treatment group (30 cases) and control group(30 cases). The patients in the treatment group were treated with TENS and physical therapy. The cases in the control group were treated with TENS only. All patients were evaluated with visual analogous score of pain (VAS) and Fugl-Meyer measure (FM) before and after treatment. ResultsThe scores of VAS and FM improved more significantly in treatment group than in control group(P<0.01).ConclusionTranscutaneous electric nerve stimulation combined with physical therapy showed more effective on shoulder pain after stroke.
