ABSTRACT
Objective To investigate the clinical efficacy of arthroscopic double Endobutton plate internal fixation in the treatment of acute acromioclavicular joint dislocation.Methods A retrospective case series study was performed to analyze the clinical data of 32 patients with Rockwood type Ⅲ or Ⅴ acute acromioclavicular joint dislocation admitted to Foshan Hospital of TCM from May 2015 to February 2018.There were 26 males and six females,aged 22-56 years [(37.7 ± 1.6)years].There were 22 patients with Rockwood type Ⅲ and 10 patients with type Ⅴ.The duration from injury to operation was 2-5 days.All patients were treated with arthroscopic double Endobutton plate internal fixation for coracoclavicular ligament reconstruction.The operation time,hospitalization time,and postoperative shoulder joint braking time were recorded.The shoulder joint function was evaluated by the Constant-Murley score (CMS),visual analogue scale (VAS),American shoulder and elbow surgeons (ASES) score,University of California Los Angeles (UCLA) score and simple shoulder test (SST) before operation and at the last follow-up.Meanwhile,complications such as infection,loosening and joint dislocation were recorded.Results All patients were followed up for 8-48 months [(27.8 ± 11.6) months].The operation time was 48-93 minutes [(65.0 ± 24.6) minutes],the hospitalization time was 3.2-10 days [(6.5 ± 2.6)days],and the postoperative braking time was 21-35.3 days [(28.2 ± 7.1)days].All patients had a grade A healing of surgical incision.The VAS was decreased from preoperative (5.7 ±2.5)points to (1.2 ±0.8)points at the last follow-up (P ＜0.01);CMS wasvincreased from preoperative (29.3 ± 3.4) points to (93.2 ± 2.1) points at the last follow-up (P ＜0.05);ASES score was increased from preoperative (28.9 ± 10.1) points to (95.7 ± 5.6) points at the last follow-up (P ＜ 0.05);UCLA score was improved from preoperative (11.6 ± 2.8) points to (34.2 ±1.5)points at the last follow-up (P ＜0.05);SST score was improved from preoperative (3.5 ±1.2)points to (9.7± 1.4)points at the last follow-up (P ＜ 0.O1).The incidence of intraoperative and postoperative complications was 16％ (5/32).In two patients,the surgery was changed to U shape fixation circulating the coracoid base due to the coracoidbone tunnel cutting out.One patient was found to have insufficient reduction and received the acromioclavicular joint operation.One patient had reduction loss due to the clavicle button collapsing,and one patient had excessive reduction.Conclusions For Rockwood type Ⅲ or Ⅴ acute acromioclavicular dislocation patients,arthroscopic double Endobutton plates for coracoclavicular ligament reconstruction has the advantages of less intraoperative trauma,quick recovery and satisfactory clinical result.However,the incidence of intraoperative and postoperative complications is relatively high,and indications should be strictly controlled.
ABSTRACT
Objective To compare the effectiveness of anterior cruciate ligament (ACL) reconstruction using Rigid-Fix for autogenous tendons fixation between by Ethibond excel polyester sutures combined with high-strength sutures and by Ethibond excel polyester sutures. Methods From October 2011 to August 2013, 48 cases of ACL rupture underwent ACL reconstruction using RigidFix for autogenous tendons fixation. Ethibond excel polyester sutures combined with high-strength sutures were used in 25 cases (observation group) and Ethibond excel polyester sutures were used in 23 cases (control group). There was no significant difference in gender, age, side, disease duration, and preoperative Lachman test, Lysholm score, and the International Knee Documentation Committee (IKDC) score be-tween the two groups ( >0.05). While the treatment and rehabilitation measures were identical. Result The opera-tion performed smoothly. Vessel, nerve and meniscus were not injured. No complication of donor site pain and myas-thenia of affected knee after operation. At 6 months and 2 years after operation, the Lachman test, the Lysholm score and the IKDC score were superior significantly to those before operation in both groups ( 0.05). Conclusion Anterior cruciate ligament reconstruction by Ethibond excel polyester su-tures combined with high-strength sutures using RigidFix for autogenous tendons fixation presented satisfactory clinical results, whether using high-strength sutures during operation needs to be further study.
ABSTRACT
Objective:To investigate effects of different treatment on celiac mast cell degranulation in mice with allergic rhinitis induced with ovum albumin (OVA).Methods:60 female mice were randomly divided into five groups,12 mice in each,which were treated with different methods.Then,the celiac mast cells were separated and degranulation rate was calculated after stained with neutral red.Results:the rates of mast cell degranulation were (15±6)%,(53±11)%,(37±13)%,(31±15)%,and (47±14)% in normal group,OVA group,point application group,hormone group,and PBS group.There is obvious degranulation in the celiac mast cells of mice with OVA-induced allergic rhinitis.Point application and dexamethasone treatment could relieve the mast cell degranulation,whereas,PBS has no effect on the mast cell degranulation.Conclusion:the mechanism of antianaphylaxis of point application may lie on stabilizing the mast cell membrane,and inhibiting degranulation to reduce the inflammatory mediator.
ABSTRACT
【Objective】 To observe the effect of electroacupuncture(EA) onlearning and memoryin vascular dementia (VD) rats andto explore its possible therapeutic mechanism.【Methods】Fifty specific pathogenfree(SPF) adult rats were randomizedintofour groups.Except the 8 rats in the pseudo-operation group(group A),the other 42 rats were induced cerebral ischemia by four-vessel occlusion method.Then the model rats were randomized into model group (group B),EAgroup(group C) and nimotop group(group D).Groups Aand B were fed with the same forage and received no medication.Group Creceived EAonthe acupoints of Baihui,Geshu,Pishu and Shenshu,and EAwas set in continuous wave with the frequency being 150Hz,once per day and lasting 15 consecutive days.Group Dreceived nimotop 12mg/kg,qd,for 15 consecutive days.After 15-day treatment,the learning and memory abilities of the rats were observed by Morris water test,the plasma carbon monoxide(CO) level was detected by double-wavelength spectrophotometer,and brain nitric oxide(NO) content was examined byspectrophotometry-colorimetry.【Results】The model rats had obvious disorders of learningand memory,their escapelatency was prolonged,thetimes swimmingacross the platforminthe original quadrant did not differ fromthose inthe other three quadrants,and plasma COand cerebral NOlevels were obviouslyincreased.In EAgroup,escapelatency was shortened,thetimes swimmingacrossthe platform inthe original quadrant were more thanthose inthe other three quadrants,and plasma COand cerebral NOlevels were obviously decreased(P
