OBJECTIVETo evaluate the clinical effect of arthroscopic excision of the os subfibulare in anterior-lateral ankle pain.

METHODSFrom December 2005 to Augest 2014, 16 patients suffering from pain associated with an os subfibulare in the anterior-lateral side of their ankles were reviewed. Among the patients,11 patients were male and 5 were female, with a mean age of (33.5 ± 15.6) years old. The mean maximum diameter of os subfibulare was (0.70 ± 0.26) cm. All the patients underwent excision of the osseous fragments, and had anatomic reconstruction of the anterior talofibular ligament if the anterior-lateral ankle was instable. The average follow-up period was (18.0 ± 4.5) months. To analyze the surgical outcome, American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot pain and function scales,visual analogue scale (VAS) and Tegner activity scale were assessed preoperatively and postoperatively.

RESULTSAOFAS scales were preoperative 60.15 ± 14.52 and postoperative 92.35 ± 5.73. There was a significant difference between them (t = -8.251, P = 0.000). The mean VAS score were preoperative 7.35 ± 0.46 and postoperative 2.45 ± 0.98. Statistical significance was also notable (t = 18.105, P = 0.000). Tegner score was significantly increased from preoperative 2.87 ± 1.12 to postoperative 5.78 ± 1.06 (t= -7.548, P = 0.000).

CONCLUSIONIrrespective of the size of os subfibulare, in patients with pain or instability associated with the os subfibulare, arthroscopic excision combined with reconstruction of ther anterior talofibular ligament or not was effective in restoring ankle function and eliminating pain.

AIM: To observe the effects of sapindoside on blood pressure,AngⅡ,Ald,ET in the blood plasma and NO in the serum in primary hypertension rat. METHODS: The primary hypertension rats were divided into 5 groups(high,middle and low sapindoside group,control group and captopril group,10 each) in a random fashion and drugs had been given by ig.for 32 days.The blood pressure was messured in the 1,3,7,32 day after administration.At the end of the 32 nd days,AngⅡ,Ald,ET in the blood plasma and NO in the serum were measured. RESULTS: Sapindoside could significantly lower the blood pressure,increase the levels of NO in serum,reduce the concentration of AngⅡ,Ald,ET in the blood plasma. CONCLUSION: Sapindoside plays an important role in decreasing the blood pressure of primary hypertension rat.

BACKGROUND:Osteosarcoma combined with pathological fracture was often treated by amputation. With clinical application of neoadjuvant chemotherapy and improvement of technology and material of the prosthesis, the limbs of patients with osteosarcoma combined with pathological fracture were reserved. OBJECTIVE:To evaluate the effect of the application of custom-manufactured artificial total knee prosthesis replacement in limb salvage treatment for patients with osteosarcoma combined with pathological fracture. METHODS:A total of 11 patients with pathological fracture with osteosarcoma located in adjacent knee Joint were enrol ed from June 2002 to September 2012. In accordance with individual condition of the patient, limb salvage treatment was designed for knee prosthesis for a tumor. Fol ow-up results were retrospectively analyzed. There were six males (54.5%) and five females (45.5%) and their age ranged from 11 to 50 years old with an average age of 25.4 years old. Onset regions:seven tumors were located in the distal femur and four tumors were in the proximal tibia. Al patients received neoadjuvant chemotherapy, and limb salvage treatment with custom-manufactured artificial knee prosthesis. The fol ow up was performed for 9 to 105 months. RESULTS AND CONCLUSION:In 11 patients after prosthesis replacement, the regional recurrence rates were 18%, lung metastasis rates were 36%. The five-year survival rate was 58%. Four patients developed lung metastases and died in 9 to 24 months postoperatively. During the last fol ow-up, Enneking score of the affected limbs was 11 to 30 points, averagely 23.3 points, with an excellent and good rate of 82%. Results indicated that combined with neoadjuvanet chemotherapy, the application of custom-manufactured artificial total knee prosthesis replacement in the treatment of osteosarcoma located in adjacent knee joint and pathological fracture achieved an ideal outcomes of the limb salvage treatment in the near future. The lone-term effectiveness was expected to be evaluated.

OBJECTIVETo study the diagnostic value of diffusion tensor imaging (DTI) in cervical spondylotic myelopathy.

METHODSTwenty healthy volunteers and fifty patients with cervical spondylotic myelopathy underwent DTI in the Affiliated Hospital of Medical College of Ningbo University from January 2014 to April 2015. Healthy volunteers served as controls. Fifty patients were divided into three groups (group A , B, C) according to cervical MRI scan standard. Group A (17 cases) had only the dura mater spinalis compressed; Group B (23 cases) showed the cervical spinal cord compressed, but no high signal in it; Group C (10 cases) had the cervical spinal cord compressed with high signal in the same level. The average apparent diffusion coefficients(ADC) and fractional anisotropy (FA)values in these examinee were analyzed and all subjects were performed fiber tracking.

RESULTSThere was no statistically significant differences in ADC and FA values in C2/C3, C3/C4, C4/C5, C5/C6, C6/C7 of control group (P>0.05). The average ADC and FA values in control group were (0.875 +/- 0.096) x10(3) mm2/s and 0.720 +/- 0.051, respectively; compared with group A,there was no statistically significant difference; compared with group B and C, there was significant difference; comparison among group A, B, C, there was significant differences.

CONCLUSIONDTI can early and accurately quantify the changes of microstructure in cervical spondylotic myelopathy. Fiber tracking can show the damage range of spinal cord lesions.

METHODS110 young men stayed at high altitude above 5 000 m were divided into iptkalim group (n = 74) and placebo group (n = 36), aminotransferase (ALT), aspartate aminotransferase (AST), gamma-glutamyltransferase (gamma-GT), creatine kinase (CK), lactate dehydrogenase (LDH), superoxide dismutase (SOD), malonaldehyde (MDA), nitric oxide(NO) and nitric oxide synthase(NOS) were detected before and after took medicines for 6 mouths.

RESULTSAfter took medication for 6 mouths, ALT, AST, gamma-GT, CK and LDH were reduced, SOD, NO, and NOS were increased, MDA were reduced, there were very significant difference (P < 0.05).

CONCLUSIONOxygen free radicals have taken part in the process of HPH, iptkalim have the effect of anti-peroxidation of lipid and protect myocardial cells stress injured by hypoxia which related with mitochondrial membrane and cell membrane's K(ATP) channel activation.

AIMTo investigate the possibility of polymethacrylate nanoparticles (NP) for antisense oligodeoxynucleotides delivery system.

METHODSThe nanoparticles were prepared by evaporating ethenol solution containing Eudragit RL100 or RS100, and then mixtured with oligonucleotides. The morphology and size were investigated by a transmission electron microscope and Mastersizer particle characterization systems, and the cytotoxicity was evaluated by Trypan Blue staining and hemolysis test. The flow cytometer was used to determine the uptake of fluorescence-labelled oligodeoxynucleotides.

RESULTSThe morphology of nanoparticles showed spherical and orderly, the average diameter was about 127 nm, and almost the antisense oligodeoxynucleotides (ODN) were loaded when NP: ODN was 6.6. The uptake of ODN was significantly increased when loaded by nanoparticles, which well depended on the nanoparticles concentration. Meanwhile, slightly cytotoxicity was observed when high dose of nanoparticles was used.

CONCLUSIONThe polymethacrylate nanoparticles appeared to be a promising vehicle for gene delivery.
