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.

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.

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

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 study the status quo and future trend of digestive system drugs used in our hospital. METHO-DS: The digestive system drugs used in our hospital between 2001 and 2005 were analyzed retrospectively in respect to drug kinds, consumption sum, DDDs, daily costs etc. RESULTS: Drugs for peptic ulcer and hepatobiliary diseases took a big proportion and experienced a year- on- year increase. No significant change was noted for the top 10 drugs on the lists of DDDs and consumption sum before and after the medical insurance reform, but their order changed a little. The DDDs of most of the cheap and effective drugs increased after the medical insurance reform. CONCLUSION: The consumption of antiulcer drugs and drugs for hepatobiliary diseases in our hospital assume an increasing tendency.

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 observe the antioxidative effect of Ginkgo biloba extract (EGb) on motor function after spinal cord injury (SCI) in rats. Methods 36 healthy adult Sprague-Dawley rats were divided randomly into EGb group (group A), methylprednisolone (MP) group (group B) and control group (group C) with 12 rats in each group. SCI model was made by Allen's mode (10 g×25 mm) at the level of the 9th thoracic vertebra (T9). Group A was given 40 mg/kg EGb daily by intraperitoneal injection, while group B was given 30 mg/kg MP at the first injection and then 5.4 mg/kg every 6 hours for 4 times. Group C received an equal volume of normal saline daily. On the 1st, 3rd and 7th days after SCI, 4 rats were selected randomly from each group. The motor function were assessed by Basso-Beattie-Bresnahan scale (BBB). The activity of superoxide dismutase (SOD) and the content of malondialdehyde (MDA) in serum were determined. Results At every time point after surgery, the BBB scores were significantly higher in groups A and B than in group C (P<0.05). Compared to group C,the activity of SOD increased and the content of MDA decreased significantly in groups A and B on the 3rd and 7th days after SCI (P<0.05).Conclusion EGb may reduce the level of oxidative stress and promote the recovery of the motor function in rats after SCI.

Objective To study the respiratory function tests reference values of healthy children in China with impulse oscillometry(IOS).Methods The respiratory function tests reference values of 102 children were measured by using masterscreen IOS and analysed it.Results Impedance and airway resistance reference values decreased as age and body height increased step by step,at the same time capacitance decreased.The difference was significant while the predicted values compared to the measured data.Conclusion We shall use respiratory function tests reference values which are established by us,and the difference is significant compared with the foreign predicted(values.)
