AIM: To evaluate acrylic resin bone cement in combination with percutaneous kyphoplasty to treat spinal metastatic tumor and reconstruct spinal stability. METHODS: Thirty-three cases with spinal metastatic tumor underwent percutaneous kyphoplasty in the Department of Spinal Surgery, Shenzhen People's Hospital between October 2006 and January 2008. All affected spines were complicated by destruction of bone or compression fracture. Under monitoring by G-arm X-ray machine, bilateral pedicle puncture was performed, followed by balloon expanding and acrylic resin bone cement injection in thoracic vertebra (3.6 mL) and lumbar vertebra (4.8 mL). All patients were followed up for 6 months to evaluate biocompatibility, vertebral height changes, pain degree pre-and post-surgery and movement ability. RESULTS: Of 49 affected vertebras in 33 cases, 43 were one-off successful, and 5 cases died of tumor metabasis. Finally, 43 vertebras were included in final analysis. The paired t-test showed the post-surgery anterior and posterior vertebral heights were significantly higher than pre-surgery [(2.6?0.6) cm, (2.2?0.6) cm; (2.9?0.7) cm, (2.6?0.6) cm; P

Diabetic peripheral neuropathy (DPN) is the most common complication of diabetes mellitus in nervous system. However, the pathogenesis is still unkown. Therapeutic options are mainly pathogenetically oriented therapy and symptomatic therapy. With an increasing understanding of the pathogenesis of DPN, many new therapies have emerged. Comprehensive therapy targeting different pathogenesis will be frequently applied in the future. In this article, the common therapy and advance in treatment of DPN are reviewed.

OBJECTIVE: To observe the efficacy of modified acupotome combined with blocking therapy in patients with carpal tunnel syndrome (CTS). METHODS: Fifty-five patients with CTS were divided into three groups, which were modified acupotome group including 26 CTS patients with 28 lesions treated by modified acupotome combined with blocking therapy, traditional acupotome group including 14 CTS patients with 16 lesions treated by traditional acupotome combined with blocking therapy, and blocking therapy group including 15 CTS patients with 15 lesions only treated by local blocking. The treatment outcome and one-year recurrence rate were observed. RESULTS: The response rate and one-year recurrence rate after operation in the modified acupotome group were 85.7% (24/28) and 20.8% (5/24) respectively, which had no significant differences as compared with 81.3% (13/16) and 38.5% (5/13) in the traditional acupotome group. The response rate and one-year recurrence rate after operation in the above two groups were both improved significantly as compared with those in the blocking therapy group which were 46.7% (7/15) and 85.7% (6/7) respectively. There were no acupotome-related adverse effects and injuries observed in the modified acupotome group. CONCLUSION: The modified acupotome is a considerable treatment method for CTS with respect to its simple manipulation and high effectiveness.

A method was developed for determining residual narasin in chicken tissues by HPLC with post-column derivatization. The samples were extracted with iso-octane. Further cleanup was performed on LC-si cartridge after centrifugation. Then the eluent was dried by nitrogen and residues were dissolved in methanol, water mixture (90∶ 10 v/v). The samples were analyzed on an Inertsil ODS-3 C18 column with a mixture of methanol-acetic acid-water as the mobile phase and vanillin as the derivatization reagent. The detection wavelength was 520 nm. The samples were quantified with the external standard calibration curve method. The limit of detection and the limit of quantification for narasin in chicken tissues were 6.0 μg/kg and 20 μg/kg, respectively. The average recoveries of narasin in chicken tissues were 76.4 %-93.1 %, the intra-assay relative standard deviations were 2.6 %-8.9% and the inter-assay relative standard deviations were 4.7%-9.7% at spiked levels of 20-1800 μg/kg. There was a good linear correlation (the calibration coefficient is above 0.9993) between the peak areas and concentration of narasin in the range of 70-10000 μg/L.
