Objective To study the characteristics and classifications of the fractures of the talar neck as well as to define the appropriate treatments and its complications. Methods 47 patients of the fractures of the talar neck were referred to our department of orthopaedics from July 1996 to November 2001. There were 32 males and 15 females with an average age of 31.6 years. The injuries were caused by fall in 13, traffic accident in 28, and others in 6. According to Hawkins classification, there were type Ⅰwith nondisplaced vertical fracture in 6 patients, which were treated non-operatively, and immobilized with a non weight bearing short leg cast; type Ⅱ in 26 patients, and type Ⅲ in 15 patients, all of which were treated in emergency with anatomic reduction and fixation with 4.0 mm lag screws through anteromedial or anterolateral approaches of the ankle. Otherwise, the arthrodesis of subtalar joint in type Ⅲ fracture were primarily performed as well. The ankles were immobilized until the fracture healed. Results The patients were followed up 2 to 5 years (average, 3.6 years). By the assessment of clinical effects depending on the complaints, functions and radiological results of the ankle and subtalar joint, 17 patients were rated as excellent, 22 patients good, 5 fair, and 1 poor, the total rate of excellent and good was 83.0%. Osteonecrosis occurred in 8 patients with 3 of type Ⅱ and 5 of type Ⅲ fractures. 3 of 4 patients with talar displacement were found with osteonecrosis or painful arthritis. The subtalar arthrosis occurred in 6 patients, 4 of which were associated with ankle arthrosis. 3 patients underwent arthrodesis because of painful arthritis of the subtalar joint or osteonecrosis of the talar body. Anteromedial skin necrosis of the ankle developed in 1 patient. Conclusion If the fracture of talar neck is not managed appropriately as early as possible, its complications are common, the fractures should be treated in emergency to reduce the incidence of posttraumatic osteonecrosis, arthrosis and malunion of the fractures.

Objective To find out if different doses of melatonin have different roles in the cause or treatment of idiopathic scoliosis, and to illuminate whether melatonin can be a substitution in the treatment of pinealectomized chickens. Methods Fifty Little-Shaoxing chickens, in which pinealectomy was performed when 3-day-old, were divided into five groups. Ten served as control group, were kept in light-dark (12h: 12h) cycle, 500 lx in daytime and 0-5 lx in nighttime after surgery. Ten served as M-5 group, were given 5 mg/kg (5 milligrams per kilogram of body weight) melatonin twice every day. Ten as M-10 group, given 10 mg/kg melatonin abdominally twice every day, ten as M-20 group, given 20 mg/kg melatonin twice every day, and ten as M-40 group, given 40 mg/kg melatonin twice every day. The light-dark (12h: 12h) cycle was the same as control group. Radiological examinations were performed on all chicken spines for scoliosis when at 3 months old. Measured of the angle of the scoliosis was taken by Cobb's technique, and the data was analyzed by statistical software. Results Overall, there was 25 chickens developed to scoliosis in all when the chickens were 3 months. The attack rate was only 56%; this rate was consistent throughout all experimental groups. In the control group, 6 chickens had obvious scoliosis, and 5 in M-5 group, 5 in M-10 group, 4 in M-20 group, and 5 in M-40 Group. And the average Cobb's angle of control group was 26.7?. There were 23.5?, 21.7?, 24.5? and 23.2? in M-5, M-10, M-20 and M-40 respectively. There was no statistical significance in the average Cobb's angle and the incidence of scoliosis among all groups. It was determined that neither the prevalence nor the pattern of the scoliosis was affected by the therapy in any of the experimental groups. Conclusion Different dose of melatonin can't reduce the rate of scoliosis in the pinealectomized chickens, and also can't prevent the development of the experimental scoliosis. The results of this study raise doubts regarding the role of melatonin in the development of scoliosis after pinealectomy in the young chicken. Melatonin acting as a vicarious therapeutic tool in the treatment of idiopathic scoliosis is premature, deserved further research.

Objective To research the indoor air pollution in offices induced by decoration and its health effects. Methods According to the completed time, the offices were divided into 6 groups (2 month group, 2-4 month group, 5-8 month group, 9-11 month group, 12-18 month group, over 5 year group). The concentration of indoor air pollutants was determined and 617 people from the decorated offices were randomly selected to finish the questionnaires on health. Results The over standard rate of formaldehyde, benzene and ammonia in indoor air was the highest in 2 month group, 100%, 87.3%, 83.9% respectively. The concentration of indoor air pollutants decreased as the time went on, about one year after decoration, the concentrations were lower than the standard limits (GB/T 18883-2002). The adverse response rate of the staff members in offices decorated group (76.4%) was significantly higher than that in the control group (30.9%) (P

Objective To study the forearm angulation deformities and observe its influence on the rotation function of the forearm.The importance of the interosseous to forearm rotation function was also analyzed. Methods Eight human cadaver specimens, with the forearm superfical and deep fascia, antebranchial extensor and flexor groups dissected off were used to study the origin and insertion of the pronator teres and supinator, and the movements of the fibers of the interosseous membrane and oblique cord during forearm rotation. Single and double fracutures of the radius and the ulna were produced in ten other human cadaver upper limb specimens with the pronator teres， supinator， interosseous membrane， oblique cord， proximal and distal radio-ulnar joint preserved. The fractures were fixed with plates and screws, and were made into models with different directions and degrees of angulation deformity. The upper limb were fixed with elbow at 90? of flexion in order to observe the effects of angulation deformities upon the forearm rotation function. Results The oblique cord and the upper third interosseous membrane fibres control the excessive pronation of the forearm while the middle and lower third interosseous membrane fibres control the excessive supination; so the oblique cord and interosseous membrane limited the rotation range of the forearm. The forearm angulate deformity resulted from single or double fractures are both be able to cause the forearm rotational disturbance; when the angular deformity exceeds 5? , disturbance of rotational function of the forearm will occur. The disorder of interosseous membrane and the oblique cord, the slope of the articulus radio-ulnaris distalis and proximalis and the osseous obstruction are the main causes of the disturbance of rotation function. Conclusion The interosseous membrane limits the scope of forearm rotation and the deformity of angulation can cause the hindrance of the forearm rotation.
