Objective To explore the clinical effect of posterior pedicle screw internal fixation in the treatment of multiple level noncontiguous thoracolumbar fractures.Methods Thirteen patients with multiple level noncontiguous thoracolumbar fractures were treated by posterior pedicle screw internal fixation.The Frankel score,percentage of vertebral compression and Cobb angle of the injured vertebral segment were analyzed to evaluate the surgery efficacy.Results All patients were followed up from 12 to 24 months ( averaged 15 months ).All cases achieved bone fusion with no implant failure.The Cobb angle of the injured vertebral segment was corrected from preoperative(22.2 ±5.3) degree to postoperative(5.3 ±3.5) degree and(6.2 ±3.6) degree at the last follow up.The percentage of vertebral compression was corrected from preoperative (45.7 ± 14.1 )％ to postoperative ( 6.1 ± 3.8 ) ％ and ( 7.2 ± 3.9 ) ％ at the last follow up.All improvements showed significant differences when compared statistically( t =15.03,t =12.05,Ps ＜0.05 ).The spinal cord function was improved 1 to 2 degree in all patients except 2 patients of grade A.Conclusion The posterior fixation with pedicle screw is a secure,safe and effective method in treating multiple level noncontiguous thoracolumbar fracture.

Objective To observe the analgesic and anti-inflammatory effects of the water extract of Glycosmis citrifolia (Willd.) Lindl.on mice and explore the mechanism. Methods The analgesic and anti-inflammatory effects were evaluated by 0.7% acetic acid-induced writhing test,the hot plate test,tests of dimethylbenzene-induced ear swelling,1% carrageenan-induced paw edema,determination of PGE2 in inflammatory feet,0.6% acetic acid-induced increase in peritoneal capillary permeability and cotton ball granuloma. Results The water extract of Glycosmis citrifolia (Willd.) Lindl.at low,medium and high doses can reduce the acetic acid-induced writhing times (P<0.01 or P<0.05),increase the pain threshold of mice (P<0.01 or P<0.05), inhibit dimethylbenzene-induced ear swelling (P<0.01 or P<0.05),1% carrageenan-induced paw edema (P<0.01 or P<0.05) and PGE2 production (P<0.01),0.6% acetic acid-induced increase of peritoneal capillary permeability (P<0.05),and the de-velopment of cotton ball granuloma (P<0.01 or P<0.05). Conclusion The water extract of Glycosmis citrifolia (Willd.) Lindl.shows analgesic and anti-inflammatory effects on mice.

To explore the expression of Beclin1 in osteosarcoma and investigate the effects of down-regulation of autophagy on the chemotherapeutic sensitivity to cisplatin (DDP), the expression of Beclin1 in 28 specimens of osteosarcoma (group A) and 19 specimens of normal bone tissues (group B) were immunohistochemically detected. The expression of Beclin1 mRNA in MG63 cells treated with different concentrations of DDP was examined with RT-PCR. After down-regulation of autophagy in MG63 cells by an autophagy inhibitor, 3-methyladenine (3-MA), the cell proliferation inhibition rate of MG63 cells treated with DDP was evaluated by using the MTT assay. The positive rates of Beclin1 were 67.85% in group A and 94.73% in group B. Its expression was lower in osteosarcoma than in normal bone tissues, with a significant difference found between them (P<0.05). RT-PCR showed that the expression of Beclin1 mRNA in the cells treated with high-dose DDP were higher than that in the non-treated cells, and no significant difference in the expression of Beclin1 mRNA was found between the cells treated with low-dose DDP and the non-treated cells. There was a positive correlation between the level of Beclin1 mRNA expression and the concentration of DDP. MTT assay showed that the proliferation inhibition rates of the cell treated with 3-MA and DDP combined were substantially increased when compared with those treated with DDP alone (P<0.01). This study demonstrated that autophagy may be implicated in the carcinogenesis of osteosarcoma, and DDP may induce autophagy in the MG63 cells. It also suggests that the down-regulated autophagy could increase chemotherapeutic sensitivity of DDP to osteosarcoma.

Objective To evaluate the early effect and safety of artificial hip replacement for treating senile osteoporosis femoral neck fractures with different prostheses choice. Methods From January 2006 to April 2014, 387 patients with senile osteoporotic femoral neck fractures received artificial hip replacement. Their average age was 65 to 98 years old,with the average of 76.9 years old. Four prostheses were used in the artificial hip replacement, including 107 cases of biological total hip,94 cases of bone cement type total hip,104 cases of biotype artificial femoral head,and 82 cases bone cement artificial femoral head. We compared the operation time,bleeding amount, postoperative ambulation time,postoperative complication rate among the four prostheses. Results The biological hip replacement were superior to bone cement type in the operation time(50±10.3 min vs 61±11.5 min), bleeding amount(149±27.7 ml vs 205±47.3 ml)and postoperative complications(21% vs 38%),with statistical significant differences(P < 0.05). Other observations showed no statistically significance. Conclusion The biotype artificial joint replacement is applicable to the younger patients with thick bone cortex and long life expectancy,while the bone cement artificial joint replacement is appropriate for weak senile patients with thin bone cortex.

Objective To observe the clinical curative effect of drug combined with psychological treatment on patients with sleep disorders after stroke.Methods A total of 180 cases of eligible patients with sleep disorders were included and randomly di-vided into control group and treatment group.Control group were treated with conventional vascular drug(estazolam,2 mg,before sleep);treatment group increased anxiolytic and sedative hypnotic drugs(venlafaxine,dexzopiclone)compared to control group.Af-ter 14 days,sleep quality,NIHSS were compared both within the treatment group and between the two groups.Results The Bar-thel index,NIHSS and PSQI of two groups had significant differences,and those index of treatment group before and after treat-ment had significant differences too(P <0.05).Conclusion Combined conventional cerebrovascular drugs with Venlafaxine,dexzo-piclone as well as psychological treatment significantly improved sleep quality of patients with acute stroke.

BACKGROUND: Dysfunction of endothelial cells is independently associated with coronary atherosclerotic heart disease. Correlation of dysfunction of endothelial cells to restenosis after stent implantation is not yet clearly determined.OBJECTIVE: To evaluate the correlation of vascular endothelial dysfunction to restenosis after stent implantation. DESIGN, TIME AND SETTING: A case control study was performed at the Department of Cardiology and Department of Heart Ultrasound, Sichuan People's Hospital from March 2005 to January 2007.PARTICIPANTS: After review, coronary angiography showed that 11 patients who occurred restenosis at the lesion region after stent implantation were included in a restenosis group, and an additional 15 patients who did not develop in-stent restenosis were included in a control group. Patients in the following conditions were excluded: over 70 years old, histories of long-term smoking, diabetes mellitus, multivessel disease, long coronary lesion and chronic total occlusion, heart failure (Killip's class Ⅲ or above), severe hepatic and/or renal insufficiency.METHODS: High-resolution ultrasound was used to assess the percentage of flow-mediated dilatation of brachial artery. Differences in endothelial function were compared between both groups.MAIN OUTCOME MEASURES: Ultrasound parameter of the brachial artery in both groups; Partial correlation analysis on control variable including sex, age, blood lipid level, diseased region and stent type.RESULTS: No significant difference was found in basic diameter of brachial artery in both groups. During reactive hyperemia, inner diameter and its absolute variation of brachial artery were smaller in the restenosis group than in the control group (P<0.01). The percentage of brachial artery flow-mediated dilatation was lower in the restenosis group compared with the control group (P=0.013). The partial correlation coefficient between the percentage of flow-mediated dilatation of brachial artery and in-stent restenosis was 0.47 (P=0.04).CONCLUSION: The endothelial dysfunction significantly decreases in patients with restenosis compared with controls following stent implantation. There is a correlation between endothelial dysfunction and restenosis.
