[Objective]To explore the academic thoughts on external treatments for paralysis syndrome in WU Shangxian's Liyue Pianwen,in order to provide guidance for the clinical application of external treatment methods in the treatment of paralysis syndrome.[Methods]By studying the relevant contents of arthralgia syndrome in Liyue Pianwen,and understanding and analyzing WU Shangxian's prescriptions for treating arthralgia syndrome,this paper summarizes the characteristics of diagnosis and treatment from two aspects:the characteristics of medication and the selection of external treatment methods,and sums up academic thoughts.[Results]On the basis of his predecessors,WU put forward the theory that"the principle of external treatment was just the theory of internal treatment,and the medicine of external treatment was the medicine of internal treatment".There were three main characteristics of the use of drugs in arthralgia syndrome:strong medicinal use and spicy fragrance;using spicy drugs with a dispersing effect to smooth Qi,and using a variety of methods for treatment together;medication along meridians and syndrome differentiation treatment.In addition,according to different clinical manifestations or syndromes,such as pain place did not move,pain drama,with sticking method,package method;cold arthralgia,with ironing method;arthralgia,with plaster method.[Conclusion]WU Shangxian enriched the external treatment of arthralgia syndrome in traditional Chinese medicine and provided a new idea for the treatment of arthralgia syndrome in modern clinic.

Objective To evaluate the safety and efficiency of robot assisted surgery guided by damage control orthopaedics(DCO) in polytraumatised patients with pelvic ring injuries.Methods A retrospective review of the pelvic fracture database was performed.Twenty-six patients who had sustained a pelvic fracture from September 2012 to December 2015 were suitable for robot-assisted minimally invasive internal fixation.They were 17 men and 9 women,aged from 23 to 58 years (average,42.6 years).Their Injury Severity Score(ISS) ranged from 20 to 31 points (average,21.3 years).According to Tile classification,6 cases were type B2,3 type B3,9 type C2 and 8 type C3.Guided by DCO,the vital signs were stabilized by all means and the fractures treated by simple and temporary external fixation before the pelvic and other fractures were managed by the robot-assisted minimally invasive internal fixation.Demographics,times to operating room (TOR),time from acute stabilization to late definitive internal fixation (TAL),time for bone union,type of robot-assisted surgery for major fractures,length of stay (LOS),postoperative complications and mortality were recorded.The outcomes of the pelvis were evaluated at the final follow-up according to the Matta criteria.Results Of the 26 patients,robot-navigated percutaneous screwing was conducted with 23 sacroiliac screws in 19,with 9 ramus pubicus screws in 9,with 6 supraacetabular screws in 4,and with 4 both-column screws in 2 cases.TOR averaged 2.7 times,TAL 5.9 days,LOS at ICU 2.1 days,ICU admission rate 46.2％ (12 of 26),hospital LOS 7.3 days,and time for pelvic bone union 79.0 days.None patients had postoperative complications related to the pelvic fracture and no one died.According to the Matta criteria at the final follow-ups,8 cases were excellent,11 good,5 fair and 2 poor,yielding an excellent and good rate of 73.1％.Conclusion Robot-navigated minimally invasive surgery plus DCO is effective,time saving and safe treatment for polytraumatised patients with pelvic ring injuries.
