Objective:To determine the three-dimensional stability of atlantoaxial reconstruction with anterior approach screw fixation through C2 vertebral body to C1 lateral mass and Gallie’s technique for C1~2 instability.Methods:25 human cadaveric specimens were randomly divided into 5 groups.The three-dimensional range of motion C1 relatively C2 was measured under five different conditions,the intact state(intact group),odontoid tape Ⅱ fracture(group OTF),fixation with posterior C1~2 transar- ticular screw(group PTS),anterior approach screw fixation through C2 vertebral body to C1 lateral mass(group ASM),ASM and Gallie’s technique(group ASMG). The obtained data were statistically analyzed. Results:The range of motion in all directions group ASMG,ASM and PTS was significantly decreased.There was significant difference among group ASMG,ASM and PTS in flexion/extension and lateral bendings by statistical analysis(P0.05). Conclusion:In vivo biomechanics studies showed that ASMG had unique superiority in the reconstruction of the atlantoaxial stability,especially in controlling the instability of flexion/extension and lateral bendings.It was one kind of reli- able surgical choice for the treatment of the obsolete insta- bility or dislocation of C1~2 joint.

Objective To study the curative effects of fixation with absorbable screw and fixative stick to treat ankle joint fracture accompanied by ankle joint dislocation.Methods 27 Patients with ankle joint fracture accompanied with ankle joint dislocation were fixed with absorbable screw and fixative stick since 1995 in our hospital.Internal,outer,backankle with SR-PLLA fixation and the distal tibiofibular syndesmosis separation by SR-PGA with absortive screw and fixative stick.Results All 27 Patients were followed up.The fracture healed up in about 10 weeks.All fracture had no displacement during the course of the treatment and no influencing function after operation.They were evaluated with Sarkision criterion.The successful rate was 92 6%.Conclusion SR-PLLA fixation,PGA absorbable screw and fixative stick are ideal fixation in treating ankle joint fracture accompanied by dislocation.

Objective To evaluate the efficacy and adverse events of oxcarbazepine(OXC) on the children with partial epilepsy.Met-hods Sixty-four children with partial epilepsy were divided into 2 groups.Forty-one newly diagnosed patients who had never accepted standard therapy entered monotherapy group,and 23 patients who had many anti-epileptic drug(AEDs) in turn with poor efficacy served as add-on therapy group.The initial dose was 4-8 mg/(kg?d).The dosage was increased by one time every 2 weeks,and should not exceed 10 mg/(kg?d) in each time.The maintenance dose was 28-40 mg/(kg?d).With open-label autocontrol method,the efficacy and adverse events of OXC were analyzed during the first 6 months of treatment both in 2 groups.Results The effective rates were 85.4%,69.6% and 79.7%,in monotherapy,add-on therapy and total groups.The seizure free rates were 53.7%,17.4% and 40.6%.It showed that the seizure frequencies between 2 groups at 6 months after therapy were significantly difference(P0.05).The common adverse events were dizziness,headache,fatigue and nausea.Six patients had dropped out because of rashes,however,they all recovered after drug withdrawal and nonspecific therapy.Conclusion The efficacy of OXC is sustained with good safety and tolerability profiles on the treatment of children patients with partial epilepsy.

In this paper, we describe mismatch, chaos, and disorder behavior during healthcare seeking. Such structural imbalances, scarcity and surplus make healthcare services less efficient. We give reasons for such phenomena in terms of long-term effects of health resource allocation policy-making and implementation, inherent de-fects within healthcare insurance, incomplete market development, and cultural issues. We then propose four policy strategies, including rational price mechanism, strict referral healthcare system, confidence in basic healthcare facili-ties, and proper healthcare cultures. These will restore orderly healthcare behavior and help realize expectations for the current healthcare reform in China.

BACKGROUND:Internal fixation has been shown to decrease intertrochanteric fracture complications in the clinic and to improve quality of life of patients. The major method widely used in the clinic is the fixation of proximal femoral nail and dynamic hip screw. ＜br> OBJECTIVE:To observe the clinical effects of proximal femoral nail and dynamic hip screw in treatment of intertrochanteric fracture in the elderly. ＜br> METHODS:A total of 60 patients with intertrochanteric fracture were randomly divided into proximal femoral nail and dynamic hip screw groups (n=30), and they respectively received proximal femoral nail and dynamic hip screw fixation. ＜br> RESULTS AND CONCLUSION:Compared with the dynamic hip screw group, operative time, blood loss, the incidence of complications one year after repair, fracture healing time and complications were lower in the proximal femoral nail group (P＜0.05). After repair, the excellent and good rate of Harris hip scores was higher (P＜0.05). No significant difference was detected in healing time of wound between the two groups (P>0.05). Results verified that compared with the dynamic hip screw fixation, the clinical effects of proximal femoral nail fixation were better, more safe and reliable in the treatment of intertrochanteric fracture in the elderly.
