Objective To provide the anatomical basis for treatment of comminuted fractures of the radial head with bending steel miniplates by observations of the proximal end of the radius (PEOTR) in adults and to investigate the effect of its application. Methods The PEOTR and the dynamic relationship between the articular circumference of the radial head and the ulnar radial notch were studied with 32 pairs of specimen of the dried radii and ulnae in adults. From Jan 1988 to Mar 1998, eleven cases of comminuted fractures of the radial head were treated with bending steel miniplates procedure; there were seven males and four females, with an average age of 35 years. According to Mason's grading, 9 cases were classified as Type Ⅲ radial head fractures, 2 cases as Type Ⅳ radial head fractures. Results The average length of the PEOTR was 41.6 mm. The radial neck deviated from the radial shaft at an angle of 164?. Then at the neutral position, the greatest range of pronation and supination of the forearm, the range of contact of radians and the range of non contact radian between the articular circumference of the radial head and the ulnar radial notch were 69?,108?,45? and 138?, respectively. The period of follow up in all cases was 20-38 months. All had bony union, with an average healing time of 8.5 months. Evaluation was done according to the criterion made by Broberg and Morrey. The result was excellent in 6 cases, good in 4 cases, and fair in 1 case. Conclusion The treatment of comminuted fractures of the radial head with bending steel miniplates is a safe and effective method.

From March 2004 to March 2005, 43 patients (49 hips) admitted to Department of Orthopedic Surgery, Fushun Central Hospital for minimally invasive total hip arthroplasty (THA) were selected, including 22 male and 21 female aged 22-79 years. All patients underwent THA with cementless prosthesis. The preoperative Harris scores were (46.2?5.3). For comparison, 35 patients (43 hips) were selected undergoing standard THA at the same period, including 22 male and 13 female, aged 31-78 years; 16 patients underwent THA with mixed prosthesis (cementless prosthesis for acetabulum; cemented prosthesis for the femur), and the others with cementless prosthesis. Their preoperative Harris scores were (43.4?4.6). The perioperative bleeding, operation time, incision length, postoperative functional recovery, and prosthetic position were compared. The THA was succeeded in all patients, and all subjects were followed up for 13.1 months averagely. The perioperative bleeding, drainage, blood transfusion and incision length in minimally invasive THA group were significantly less than standard group (P

Facing the lack of the health service management professionals'vocational adaptability in medical college,we should improve their ability of professional practice,communication skills,professional knowledge and awareness of social responsibility in order to achieve the training objectives.

The etiology of rotated maxillary central incisor is unclear, but it has a clear familial tendency. Except for the environmental factors, gene expression directly influences craniofacial growth and the types of malocclusion deformity. In this article, a case of 180° rotated left maxillary central incisor of a male with family history of the deformity was reported. Relevant literature was also reviewed.

Objective To explore the mechanism of immunologic injury in patients with Tourette's syndrome(TS). Methods The serum level of anti-brain antibody ( ABAb) , antinuclear antibody ( ANAb) , soluble IL-6 receptor (sIL-6R) and soluble gpl30(sgp130) in patients with TS were analyzed by commercially available ELISA kits,and the titer of anti-streptolysin O ( ASO) in TS and in control was examined with latex enhanced immunoturbidimetry. Results The level of sIL-6R and sgpl30 was significantly elevated in TS compared with control group [(44. 1 ± 15.8)ng/mL vs (30. 3 ± 9. 0) ng/mL and (69. 0 ±24. 6)ng/mL vs (47. 3 ±14. l)ng/mL,P <0. 01 respectively]. ASO titer(250 U/mL) was found higher in TS than that in control(P <0. 01). The positive rates of anti-brain an-tibody and antinuclear antibody in TS were higher than that in control group (66% vs 4% and 53% vs 25% , P <0. 01 respectively). The level of ABAb negatively correlated with sgpl30 concentration( r = 0. 375, P <0. 05 ). Conclusion IL-6 signal transduction might be involved in Tourette's syndrome to lead the function enhancementand start cascade of feedback inhibition, because of elevated levels of slL-6R, sgp130, ANAb and ABAb in serum.Autoimmune-related injuries may potentially explain the pathogenesis of the disease.

Objective:To understand the related factors of tic disorders(TD) and early intervention among schoolchildren.Methods:Using stratified-cluster random sampling techniques,4,020 children were selected from 61,836 schoolchildren in Daxing district of Beijing.Totally 4,020 children and their parents were asked to fill in a self-designed questionnaire covering both motor and vocal tics and general information.A three-stage procedure was used:screening,interview and clinical investigation.A total of 3,813 children were investigated successfully.The children who were reported with tic symptoms as well as those who were reported by their teachers or classmates were surveyed according to the TD criteria in Diagnostic and Statistical Manual of Mental Disorders-Fourth Edition(DSM-Ⅳ).Eighty-six TD children were investigated respectively about the related factors of TD,and 86 healthy children matched in age,sex and grade were selected as controls.Telephone interview was carried out to find the doubtful TD cases in family members.Those people identified as having tics underwent a semistructured interview to determine whether they had TD according to DSM-Ⅳ criteria.Related risk factors of TD were investigated according to self-designed formulary medical history sheet. Results:Positive TD inheritance family history(7.0%),abdominal delivery style(36.0%),carbonate drink(10.5%),obesity(14.0%) and psychological stress were risk factors of TD(P<0.05).The multivariate analysis of variance indicated that inheritance family history,delivery style,dwelling environment,carbonate drink,parent-child relation,hobby,underachieve,self-care ability were closely related to the high incidence of TD (P<0.05).Conclusion:The occurrence of tic disorders may be related to multiple interacted factors.Early intervention is most important.

Objective To carry out the urban community residents satisfaction investigation and analyze the present situation of public service of medical institutions,to discuss under the new situation,the development of medi-cal and health innovation mechanism,thus to meet the multi -level and diverse people health services demand. Methods Random stratified sampling of Qingdao city community residents,1 430 people,adopted the method of the questionnaire about the present situation of public hospital and community health service center and the satisfaction was investigated.Results Of Qingdao city community residents,1 430 people chose to large public hospital patients (65.8%),community health service centers (37.3%).In a large public hospital from visits to the end,took at least half a day to account for 69.5%,more than a day (18.7%);Unreasonable process part (45.2%),such as hospital formalities complex,paper take inconvenient,medical guide was too little,expert outpatient service limit number,to see the doctor for a long time,adjust time was shorter,the doctor for the patient and the lack of patience,etc.The process was reasonable and convenient accounted for 40.0%.Think of large public hospital service attitude,subject to further improvement accounted for 58.2%;Think good service attitude,the very satisfied accounted for 30.7%.Think that community health service center service attitude good,very satisfied accounted for 43.2%;Think the service attitude in general,efficiency was 37.9%.96.1% of the respondents believed that society should form a public -private joint diversified do medical pattern,provided residents with various preferential policies.98.4% of the respondents expected countries to optimize the medical service resources allocation,promoted resources with high quality and the countryside in poor areas.Conclusion At present,most of the patients choose to large public hospital,process and service attitude is the key of the need to improve.Large public hospitals and community health service center should strengthen the cooperation and formation mechanism of innovation and development,and make the patients more options,so as to get better medical service quality.
