Objective To evaluate the role of fibroblast growth faetor-2 (FGF-2) in neuropathic pain (NP) in rats.Methods One hundred male Sprague-Dawley rats,aged 7 weeks,weighing 200-250 g,were randomly divided into 4 groups (n=25 each): sham operation group (group S),group NP,phosphate buffer solution (PBS) group and FGF-2 antibody group (group Ab).FGF-2 antibody 18 μg (40 μl) was injected intrathecally at 1,6,9,13,16 and 20 days after operation in group Ab,while the equal volume of PBS was injected intrathecally in group PBS.Spinal nerve injury was produced by exposing the sciatic nerve and its branches and ligation and transection of tibial nerve and common fibular nerve.Pain behavior was assessed at 1 day before operation and at 1,4,7,14 and 21 days after operation.The paw withdrawal mechanical threshold (PWMT) was measured.The animals were then sacrificed and the lumbar segment (L4-6) of the spinal cord was obtained for determination of the contents of tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6) in the spinal cord.Results Compared with group S,the PWMT was significantly decreased and the contents of TNF-α and IL-6 in the spinal cord was significantly increased in groups NP,PBS and Ab (P < 0.05).The PWMT was significantly higher and the contents of TNF-α and IL-6 in the spinal cord were significantly lower in group Ab than in groups NP and PBS (P < 0.05).Conclusion FGF-2 is involved in the occurrence and development of NP and induction of the inflammatory response in the rat spinal cord in involved in the mechanism.

AIMTo establish an assay method for the determination of three kinds of biologically active components, five compounds (emodin, chrysophanol, baicalin, wogonin and berberine hydrochloride) simultaneously in Sanhuang tablets.
METHODSHPLC was carried out, using a C18 column (150 mm x4. 6 mm ID, 5 microm) set at 30 degrees C, acetonitrile-0.02 mol x L(-1) acetic ammonium (adjusted pH to 3. 50 with acetic acid glacial) as mobile phase (using gradient) with flowing rate 1. 00 mL x min(-1) and detected at 270 nm.
RESULTSThe calibration curve of emodin was linear from 0.020 7 microg to 0.207 microg with r = 0.999 9, the average recovery was 99.65% with RSD 1.25%. The calibration curve of chrysophanol was linear from 0.052 microg to 0.52 microg with r = 0.999 9, and the average recovery was 100.36% with RSD 0.96%. The calibration curve of baicalin was linear from 0.250 5 microg to 2.505 microg with r =0.999 8, and the average recovery was 100.22% with RSD 1.29%. The calibration curve of wogonin was linear from 0.047 6 microg to 0.476 microg with r = 0.999 9, and the average recovery was 98.97% with RSD 1.20%. The calibration curve of berberine hydrochloride was linear from 0.053 12 microg to 0.531 2 microg with r = 0.999 5, and the average recovery was 96.02% with RSD 2.02%. The established method had also been used in the determination of the 5 compounds in 10 different batches of Sanhuang tablets.
CONCLUSIONThis method was proved to be accurate and quick, and can be used for the quality control of the preparation all-around.

Objective To investigate the clinical characteristics,minimal invasive operation technique and perioperative management of lateral ventrieular tumors.Methods The clinical characteristics,image diagnosis,surgical approaches and postoperative management and surgical outcomes of 65 consecutive cases of lateral ventricular tumors were retrospectively analyzed.Results In our series,total resection was achieved in 54 cases,and subtotal resection was achieved in 11 cases.Lateral ventricular tumors were mostly found in male and in the left side.Headache caused by increased intracranial pressure was the most common clinical symptom.Ependymocytoma and astrocytic glioma are the most common pathologic diagnosis.Postoperative complications included fever (26 cases),hydrocephalus (9 cases),intraventricular hematoma (7 cases) of which 2 cases were evacuated by craniotomy,epilepsy (7 cases),wound infection (3 cases).Postoperative death was happened in 3 cases.Two of them died of respiratory failure due to postoperative epilepsy.Conclusion Early discovery of lateral ventricle tumors,meticulous operation,subtle micromanipulation and right postoperative treatment are the criticality to improve the rate of total resection of lateral ventricle tumors through microsurgical treatment and reduce postoperative complications and mortality.

Objective:To investigate the efficiency of carbon nanotube(CNT)-PAMAM mediated entrance of anti-survivin oligonucleotide into HepG2 cells,and its effects on the proliferation of HepG2 cells.Methods:CNT-PAMAM-anti-survivin oligonucleotide compounds were prepared and characterized by AFM and 1% agarose gel electrophoresis analysis.TEM was used to observe the distribution of CNT-PAMAM-ASODN compounds in HepG2 cells.CNT-PAMAM-ASODN compounds were added into the medium and co-cultured with HepG2 cells for 24 h,48 h,72 h,and 96 h at 37℃,5% CO_2.MTT method was used to detect the effects of ASODN and CNT-PAMAM-ASODN on the proliferation of HepG2 cells.Results:CNT-PAMAM-ASODN compounds were successfully synthesized via AFM and agarose gel electrophoresis.TEM showed that the compounds were located in the cytoplasm.When CNT-PAMAM-ASODN(1.0 ?mol/L)and ASODN(1.0 ?mol/L)were used for a 48 h culture,the inhibitory rates of HepG2 cells were(45.97?4.28)% for CNT-PAMAM-ASODN compounds group,(9.33?0.85)% for ASODN group,and(6.37?0.69)% for CNT-PAMAM group.CNT-PAMAM-ASODN compounds at 1.5 ?mol/L inhibited HepG2 cells by(70.22?7.25)%,and the inhibitory effects were in a time-and concentration-dependent manner.There was statistical difference between experiment group and control group(P
