Objective To analyze diagnosis and management of traumatic atlantal fractures complicated with disruption of the transverse atlantal ligament. Methods Twenty-six patients with traumatic atlantal fractures complicated with disruption of the transverse atlantal ligament, 20 acute ones and six old ones, were managed in our department from March 1995 to March 2005. All the patients had the symptom of neck pain and a certain extent of neurological deficits. The radiographic examination showed that there were fractures in the anterior arch or/and lateral mass of the atlas and that the atlanto-dental interval (ADI) in these patients was 4 to 7 mm. Twenty-one cases were operated on with occipitocervical or atlantoaxial fusion immediately after injury. Five cases received conservative treatment. Results All were followed up for 15 (from 6 to 24) months on average. The 21 cases treated operatively reported relieved symptoms. Four of the five conservative treatments succeeded, but one of them underwent a successful atlantoaxial fusion because the original conservative treatment had failed. Conclusions The severity of clinical symptoms mostly depends on the degrees of atlantal displacement and cord compression. Diagnosis should be made on the basis of the ADI change as well as clinical presentations. For patients who have potential risk of atlantoaxial instability, occipitocervical or atlantoaxial,usion should be performed early.

Objective To investigate temporal expression of estrogen receptor (ER) in myocardium at non-infarct zone after acute myocardial infarction (AMI) in rats. Methods 120 healthy, male SD rats were randomly divided into three groups: control group, left anterior descending coronary artery (LAD) occlusion group and sham operation group with 8 rats in each group. The murine AMI-model was established by LAD ligation after anesthetization, and the rats in both LAD occlusion group and sham operation group were sacrificed at 2h, 4h, 8h, 12h, 1d, 2d, 4d, and 9d after occlusion. Myocardial samples were collected. H.E and ER immunohistochemical staining were performed. The results were quantitatively evaluated by image analysis system. The data were statistically analyzed with SPSS for Windows. Results ER expression in non-ischemic cardiomyocytes after LAD occlusion became more prominent with extension of LAD occlusion period. There was no significant difference within 12h after AMI, while ER expression was enhanced significantly 24h after ischemia. The enhancement were more evident from 4 to 9 days. Conclusion The results suggested that protective role may be initiated in response to acute ischemia in cardiac cells at non-infarct zone by increased ER expression after LAD occlusion in rats.

OBJECTIVETo explore the clinical effects of one-stage hemiarthroplasty in treating fresh subtrochanteric fracture combined with old femoral neck fracture.
METHODSFrom October 2003 to October 2013, 7 patients with fresh subtrochanteric fracture and old femoral neck fracture were treated with hemiarthroplasty in one stage. There were 5 males and 2 females, aged from 69 to 80 years old with an average of 74.5 years. According to the Garden classification, 2 cases were type IV and 5 cases were type V. According to the A0 classification of subtrochanteric fracture, all cases were type A1 (long oblique femoral subtrochanteric fractures). Biological coating long handle femoral prosthesis was used in the patients. The hip joint functions were assessed according to Charnley scoring system after all hemiarthroplasty.
RESULTSSeven patients were followed up from 12 to 24 months with an average of 18 months. There were 1 case with urinary system infection and 1 case with deep venous thrombosis. Of all, 5 cases recovered the walk ability at 6 months after operation and 2 cases could walk with the help of the crutch at 1 year after operation. According to Charnley scoring system to assess the hip joint function, the total Charnley scores reached 15.0±2.5, and 4 cases got an excellent results, 2 good, 1 fair.
CONCLUSIONArthroplasty through anterolateral approach can obtain satisfactory clinical effects in treating fresh subtrochanteric fracture combined with old femoral neck fracture, it has advantages of good joint stability, little pain, less complication, quickly recover, early activities on fields.

Objective To explore the difference between the stapes prosthesis surgery with microscope and with otoscope. Methods Fifty-four patients with otoselerosis accepted stapes prosthesis surgery with the same kind of stapes prosthesis, done in the same operative method by the identical surgeon.All the operations were done with microscopes or with otoscopes. The operative difference and therapeutic effects between microscope surgery and otoscope surgery were analysed. Results There was no difference in the postoperative heating improvement between microscope surgery and otoscope surgery; the operative time of microscope surgery [(30±7)] min was much shorter than that of otoscope surgery [(60±5)] min,with significant statistical difference. Conclusions Stapes prosthesis surgery with microscope, which has advantages of bimanualness, easiness, and short operative time, is much better than that with otoscope.Thus, microscope is still the preferred magnifying equipment in stapes prosthesis surgery.

Objective To systematically review the existing evidence about the effect of medial and lateral (crossed) entry pins versus only lateral entry pin fixation on the supracondylar fractures of the humerus in children.Methods Eligible studies were identified in Cochrane library,the Cochrane Bone,Joint and Muscle Trauma Group (till March 2011 ),Medline (from 1966 to March 2011 ),EMbase (from 1966 to 2011 ),CBM (from January 1979 to March 2011 ),PubMed,Wanfang Data (from 2000 to March 2011 ) and CNKI and the references of the included studies and several Chinese orthopedic journals were manually searched.Then,the randomized controlled trials (RCTs) and quasi-randomized controlled trials (CCTs) about two entries (crossed and only lateral pinning) for supracondylar fractures of humerus in children were collected.After evaluation of methodology with the enrolled studies,available data was extracted and systematic review was conducted via the method recommended by the Cochrane Collaboration.Results In total,five RCTs involving 311 patients were involved.Compared with the preoperative data,the meta-analysis results showed no significant difference in reduction stability in terms of change in Baumann angle and Carrying angle between the two groups.For the postoperative function outcome including complete reduction,Flynn grade and full return to function,no significant difference was found between the two groups.For the postoperative complications,there was no difference in the infection of pin tract,though lateral entry resulted in a significant lower incidence of the iatrogenic nerve injury compared with the medial and lateral entry.Conclusions With the Kirschner wire fixation for supracondylar fractures of humerus in children,current existing evidences indicate that the lateral entry of pinning has similar results in reduction stability,function outcome and incidence of pin tract infection compared with medial and lateral entry.Nevertheless,lateral entry,as a safe pinning technique,may effectively decrease the risk of iatrogenic nerve injury
