BACKGROUND: It is often seen in clinical practice that children, aged3-15 years, suffer from knee pain of unknown cause at night, which occurs frequently. Most of them can be called "pain of growth".OBJECTIVE: To analyze the related factors of knee pain in adolescents and observe the interventional effect of alpha-D3 (α-D3).DESIGN: Case control analysis, self-control analysis SETTING: Department of Orthopaedics, Jinshan Hospital Affiliated to Shanghai Fudan University PARTICIPANTS: We admitted 22 children outpatients, aged 3 to 15years, who suffered from recurrent attack of knee pain of unknown reasons and received treatment in Jinshan Hospital Affiliated to Shanghai Fudan University from June 1998 to August 2002, servingas group A. Another 20children outpatients of fracture recovered for half a year were recruited simultaneously, serving as Group B (control group).METHODS: Group A adopted the therapy of α- D3 of 0.25 μg taken orally once everyday for successive 7 days then stopped to observe the symptoms for the next three weeks. Four weeks was one therapeutic course.If the pains were still alive or reoccurred, another therapy period was needed until they vanished. The contents of bone gla protein (BGP), blood calcium (Ca2+), blood phosphorus (P3+), blood magnesium (Mg2+), alkaline phosphatase (ALP) and bone mineral density (BMD) of patients were detected between Group A and Group B. GBP index and change of pain in knee at night was observed with α-D3 before therapy and 1,3 and 6months after therapy. After one therapy period, the levels of blood Ca2+, P3+,Mg2+, ALP, BGP, CT, urine and X-ray of knees were detected again, so was BMD after 6 months.MAIN OUTCOME MEASURES: ① Blood Ca2+, P3+, Mg2+, ALP contents of children patients were detected before and after therapy . ② In the Group A, content of BGP was detected before and 1,3 and 6 months after therapy, and BMD before and 6 months after therapy; The above indexes were detected 6 months and one year after bone fracture healing in the control group. ③ Therapeutic effect of α-D3.RESULTS: All the 42 patients entered the stage of result analysis. ① The levels of blood Ca2+, P3+, Mg2+, ALP of patients who suffered pain in knee were all normal before and after therapy . ②BGP content of patients in the control group was significantly lower 1 year after bone fracture healing than 6 months after bone fracture healing [(7.06±0.74), (7.44±1.16)μg/L,P ＜ 0.01]; BGP content of patients in Group A was 15.98 μg/L before therapy , which was significantly higher than that in the control group .BGP content was (12.12±2.2), (10.6±81.31), (7.60±0.95)μg/L , respectively in 1,3 and 6 months after therapy. There was significant difference of BGP content between before and after therapy (P ＜ 0.05). ③ There was no significant difference of BMD of patients between two groups (P ＞ 0.05).④ Symptoms of pain in knee at night improved or disappeared after α-D3therapy, and the therapeutic time was 9 to 83 days.CONCLUSION: Although the knee pain of adolescents and children at night can not reach the diagnostic criterion of rachitis, it is still correlated with the deficiency of bone mineralization, in clinical practice, the BGP determination should be used as a means of monitoring the pain of unknown cause. There is significant effect using vitamin D3 in treatment of knee pain of children at night.
Résumé
Objective To recognite the importance of early emergent management of and prevention therapy of complication in acute cervical spine injury. Methods early emergent support and 8 types and 715 early complications and their prevention and management in 194 cases with acute cervical spinal cord injury admitted through 1989 to 1995 were reviewed.Results Mortality in early stage can be markedly reduced with routinely and standardization of early emergency treatment obviously reduced the mortality procedure,pulmonary complication being the main cause of death, while early complications can delay surgical treatment,increase the cost and the staying in hospital and reduce difficulty of rehabilitation.Conclusion Early complication occurring in the first days with its own feature, prevention or treatment properly will be benefit for the treatment of the neural lesion and following rehabilitation.

Objective To observe the indications for early surgical trea tment of thoracolumbar burst fracture (TLBF). Methods 139 cases who had been def initely diagnosed as TLBF were analyzed retrospectively. They were divided into 2 groups: operation and non-operation. 47 patients had non-surgical treatment, such as bed-rest plaster brace. 92 patients had surgical treatment with plate and root screw. Spinal cord functions were evaluated according to the ASIA metho d. Results All patients were followed up for 6 months to 10 years (averaged 6 y ears and 2 months). Their average kyphosis angle measured with Cobb method was 2 3.5? before the operation and 8.5? after the operation. The average degree o f middle column posterior convexity was 25%～85% before the operation (averag ed 33%) and 0～53% after the operation (averaged 12%). The average height of anterior column was 45% before the operation and 85% after the operation. T he average degree of spinal stenosis was 30%～85% before the operation (avera ged 55%) and 0-50% after the operation (averaged 20%). There were more case s whose neural function recovered to grade E in the operation group than in the non-operation group (P
