Objective To detect the initial results of total hip arthroplasty (THA) after failure of internal fixation of femoral neck fractures and investigate the key points in surgical procedures and prosthesis selection.Methods A retrospective analysis was performed on 36 cases who had THA for femoral neck fractures due to the initially failed internal fixation between January 2007 and December 2012.There were 21 males and 15 females,with age ranging from 46 to 72 years (mean,58.6 years).After internal fixation,13 cases were complicated by femoral head necrosis,eight fracture nonunion,and 15 fracture nonunion combined with femoral head necrosis.All the 36 cases had cementless THA,including proximally fixed stem in 25 cases and distally fixed stem in 11 cases.Harris hip score was assessed before operation and at follow-up.Results All the cases received a follow-up of 26-52 months (mean,32.5 months).Mean Harris hip score improved from 26.3 to 83.6,including excellent results in 12 cases,good in 22,and fair in two,with excellence-good rate of 94％.Conclusion With respect to the failed internal fixation of femoral neck fractures,THA is an effective remedial method to improve hip function and quality of life of the patients.

[Objective]To explore the surgical management and its results of intercondylar fracture of humerus through approach of osteotomy of olecranon(AOO) with dual anatomical steel plate DASP.[Method]From July 2002 to March 2006,26 patients of intercondylar fracture of humerus were treated surgically through AOO,and the fracture was reduced and fixed with DASP.The patients were 19 males and 7 females with a mean age of 35 years (range 15～46 years),According to Riseborough and Radin classification,type Ⅱ fracture was found in 6 cases,type Ⅲ in 18,type Ⅳ in 2.Early rehabilitation exercises was taken.[Result]Twenty-five fractures were satisfactory reduced but one not too good,none had incision infection,injuries of the ulnar nerve.Twenty-two patients were followed up from 6 months to 19 months(average 13.5 months),of these 22 patients,all the osteotomies healed in 17 weeks averagely(range 14～24 weeks) and the injuried ulnar nerve recovered completely.The function of the elbow(according to Cassbaum scale) showed excellent in 5 cases,good in 13,fair in 3 and poor in 1.the good-excellent rate was 81.8%.[Conclusion]The technique of DASP for the treatment intercondylar fracture of humerus through transolecranon approach offers many advantages,such as sufficient exposure easy to get anatomical reduction,stable fixation and earlier exercise.

Approximately one-quarter of ischemic stroke occurred in vertebrobasilar artery system. Atherosclerotic vertebrobasilar artery stenosis is one of the major causes of posterior circulation stroke. In addition to the conventional medical and surgical treatment, endovascular intervention has received more and more attention, and it has become the most promising therapeutic approach.

OBJECTIVEThis study investigated the influence of different designs and porcelain/glaze firing on the marginal and internal fit of three kinds of computer aided design/computer aided manufacturing (CAD/CAM) zirconia ceramic implant-supported crowns.

METHODSThree groups of zirconia ceramic implant-supported crowns with different designs were produced from copings by using a Cercon CAD/CAM system (n = 8). The first two groups comprised double-layer crowns (zirconia coping + veneer) with regular (Group A) and full circumferential zirconia-collar marginal designs (Group B). The third group was composed of anatomic single-layer zirconia crowns without cores (Group C). Initially, the marginal and internal gaps of the copings and crowns were individually replicated by light-body silicon and then measured by micro-computed tomography scanning before and after porcelain/glaze firing. Five measurements were employed: vertical marginal gap (MG); horizontal marginal discrepancy (HMD); chamfer area (CA); axial wall (AW); and axial-occlusal transition area (AOT). Statistical analyses were performed by SPSS 17.0.

RESULTSHMD measurements in Group A were statistically higher than those in Groups B and C (P < 0.05), regardless of whether the values were obtained before or after porcelain/glaze firing. By contrast, the HIMD measurements in Groups B and C showed no significant difference (P > 0.05). Moreover, no differences were noted in MG, CA, AW, and AOT among the three groups (P > 0.05). All the measurements in the three groups showed no significant change after porcelain/glaze firing (P > 0.05), except for MG in Group A, which significantly decreased (P < 0.05).

CONCLUSIONThe marginal fits of the double-layer crowns with full circumferential zirconia-collar and the anatomic single-layer zirconia crowns were superior to that of the double-layer crowns with regular margins. The MG of the crowns with regular margins was obviously influenced by porcelain firing.

Objective To study the effects caused by novel antipsychotics quetiapine and aripiprazole on concentrations of platelet 5-HT in patients with schizophrenia,and to explore the relationships among the change of platelet 5-HT concentrations, psychiatric symptoms and the sensitivity of therapy. Methods Sixty-eight patients with schizophrenia meeting International Classification of Diseases-10 (ICD-10) were enrolled in the study. They were divided into quetiapine group(n=34) and aripiprazole group(n=34) according to the sequence of admis-sion. The platelet 5-HT concentrations were measured with high performance liquid chromatography method(HPLC-ECD). The positive and negative syndrome scale (PANSS) was used to evaluate the psychopathology. Treatment emergent symptom scale (TESS) was used to evaluate the side effects. PANSS,TESS were used at pre-treatment,the end of 4th and 8th week of treatment. Results The platelet 5-HT concentrations in two groups were higher af-ter 8 weeks treatment,but had no statistically significant difference (P>0.05). In quetiapine group, the platelet 5-HT concentration was (458.89±233.36) ng/10~9 at the pre-treatment, and (554.31±313.22) ng/10~9 at the end of treatment (t=1.709, P=0.099). In aripiprazole group, the platelet 5-HT concentration was (409.83±149.32)ng/10~9 at the pretreatment, and (421.27±245.96)ng/10~9 at the end of treatment (t=0.321, P=0.819). There was no difference between two groups(P>0.05). Stepwise regression analysis showed the changing rate of platelet 5-HT concentrations was positively correlated with the dosage of quetiapine (r=0.385, P=0.039).It was positively correlated with the decreasing rate of PANSS in aripiprazole group(r=0.391, P=0.040). Con-dusion The changes of psychiatric symptoms and the dosages of antipsychotics maybe have intimate relationships with platelet 5-HT concentrations in the course of medication.
