BACKGROUND: How to effectively treat recurrent osteoporotic vertebral compression fractures in the elderly over 65 years has become an issue of attention in the clinic. OBJECTIVE:To evaluate the clinical efficacy of percutaneous vertebroplasty with polymethylmethacrylate bone cement for treating elderly recurrent osteoporotic vertebral compression fractures. METHODS:Twenty-four patients with elderly osteoporotic vertebral compression fractures were divided into polymethylmethacrylate bone cement group (minimaly invasive group) and conservative treatment group on a voluntary basis (n=12 per group). Visual analog scale score for low back pain, Oswesty dysfunction index, ratio of the anterior/posterior margin height of the injured vertebra, Cobb angle and adverse reactions were compared between the two groups before and after treatment. RESULTS AND CONCLUSION:The 12-month folow-up was completed in al the patients. There was one case of bone cement breakage during treatment in the minimaly invasive group and one case of lower limb deep venous thrombosis in the conservative treatment group at 1 month after treatment. Compared with the conservative treatment group, the visual analog scale score, Oswesty dysfunction index, and Cobb angle were significantly lower, but the ratio of the anterior/posterior margin height of the injured vertebra was significantly higher in the minimaly invasive group at 3 days, 1, 3, 6 and 12 months after treatment (P < 0.05). These findings indicate that percutaneous vertebroplasty with polymethylmethacrylate bone cement for elderly recurrent osteoporotic vertebral fractures can strive for short-term pain relief and long-term recovery of the vertebral height and spinal Cobb angle, thereby significantly improving patient’s quality of life.

Aim To explore the effect of gastrin17 on expression of ?-catenin/Tcf-4 pathway in colonic carcinoma cell line——Colo320WT.Methods Colo-320WT cells were treated with 10-8 mol?L-1 gastrin17 in time-dependent way(0、1、6、12、24、48 h),while treated with 10-6 mol?L-1 L365,260(gastrin17 receptor blocker) for 30 minutes and treated with gastrin17 again for 12 h. The expression levels of ?-catenin in TX-100 solution fraction(cytoplasmic) and TX-100 insolution fraction(cytoskeleton bound) of Colo320WT cells, and the expression levels of ?-catenin/Tcf-4 complex were detected by coimmunoprecipation and Western blot. The expression levels of c-Myc and cyclinD1 were assayed by Western blot.Results Expression levels of ?-catenin in TX-100 solution fraction were decreased apparently, but increased again by L365,260 blocking. Expression levels of ?-catenin in TX-100 insolution fraction were on the contrary. Expression levels of ?-catenin/Tcf-4 complex increased apparently.Expression levels of c-Myc and cyclinD1 in Colo320WT treated by gastrin17 were higher markedly than those of Colo320WT untreated and treated by L365,260.Conclusions Gastrin17 interacted with CCK-2R and effected significantly distribution of ?-catenin in Colo320WT and activated ?-catenin/Tcf-4 pathway which led to c-Myc and cyclinD1 high expression,the way gastrin17 decreased cell-cell cohesion and increased tumor cells invasion and metastasis further.

Aim To investigate the effects of gastrin-17 on NF-?B signaling pathway in human colon cancer cells-Colo320WT. Methods All subjects were divided into four groups: control, gastrin-17,gastrin-17 + L365,260 ( gastrin-17 receptor blocker) and L365,260 group. Concerning gastrin-17 group,Colo320WT cells were treated by gastrin-17 for 12 h. Concerning gastrin-17+L360,265 group,Colo320WT cells were pretreated by L365,260 for 30 min and then were treated by gastrin-17 for 12 h. Concerning L365,260 group,Colo320WT cells were pretreated by L365,260 for 30 min. NF-?B DNA binding activity was determined by electrophoretic mobility shift assay (EMSA). Expressions of uPA protein and mRNA were assayed by Western blot and RT-PCR,respectively. Results NF-?B DNA binding activity increased more greatly in the Co-lo320WT cells stimulated by gastrin than that of the control group. And the expressions of uPA protein and mRNA were up-regulated more markedly than those of the control group. The above responses resulting from gastrin-17 were partly blocked by gastrin-17 receptor blocker,L365,260. Conclusion Gastrin-17 may activate NF-?B signaling pathway in human colonic cancer cells Colo320WT.

Aim To investigate the effects of gastrin-17 on NF-κB signaling pathway in human colon cancer cells-Colo320WT.Methods All subjects were divided into four groups: control, gastrin-17,gastrin-17+L365,260 (gastrin-17 receptor blocker) and L365,260 group.Concerning gastrin-17 group,Colo320WT cells were treated by gastrin-17 for 12 h.Concerning gastrin-17+L360,265 group, Colo320WT cells were pretreated by L365,260 for 30 min and then were treated by gastrin-17 for 12 h.Concerning L365,260 group,Colo320WT cells were pretreated by L365,260 for 30 min.NF-κB DNA binding activity was determined by electrophoretic mobility shift assay (EMSA). Expressions of uPA protein and mRNA were assayed by Western blot and RT-PCR, respectively.Results NF-κB DNA binding activity increased more greatly in the Colo320WT cells stimulated by gastrin than that of the control group. And the expressions of uPA protein and mRNA were up-regulated more markedly than those of the control group. The above responses resulting from gastrin-17 were partly blocked by gastrin-17 receptor blocker, L365,260.Conclusion Gastrin-17 may activate NF-κB signaling pathway in human colonic cancer cells Colo320WT.

Objective To study the of effets of hFRNK gene transfected by adenoviral vector on human colon cancer cell invasion induced by gastfin.Methods The subjects were divided into three groups:control,G17 and hFRNK group.The G17 group was treated with 100 umol/L gastrin 17 for 12 h to induce Col0320WT cells.As to hFRNK group,Colo320WT cells were infected by pAdhFRNK(MOI:100)for 48 h after transient transfection of pCR3.1-CAR for 48 h and subsequently treated with gastrinl7 for 12 h,and the control group was untreated Colo320WT cells.Expression of phosphorylated FAK(PY397)were assayed by western blot.FAK(PY397)at lamellipoda was observed with a confocal microscope.The influence of hFRNK on formation of signal complex of FAK-Src-p130Cas-Dockl80 was assayed with coimnlunoprecipitation and immunity blotting.Activity of Rac-GTPase was determined by pull down.Results Phosphorylated FAKTyr397 drastically increased with the induction of gastrin.Compared with that of G17 group,FAK (PY397)expression decreased and little FAK(PY397)was found at lamellipoda,at the same time,the signal complex of FAK-Src-p130Cas-Dockl80 did not form,and the activity of Rac decreased.Conclusion hFRNK gene may block gastrin-induced FAK phosphorylation,prevent formation of the signal complex,prevention and treatment of tumor invasion and metastasis.

Objective To study the short-term(≤1 year) effect of video-thoracoscope in the treatment of chronic obstructive pulmonary diseases (COPD) accompanied with pneumothorax.Methods 52 COPD cases with pneumothorax from June 2005 to June 2007 were divided into thoracoscope group(n=28) and open heart group(n=24).The patients were followed up at 1,6 and 12 month after surgery,for determination of BODE index,including body mass index,air block,difficulty in respiratory and motor ability.Results No operative death and servere complicatins occurred.Pneumothorax did not relapse.One month after surgery,air block was[(58.62±15.73)% vs (50.12±11.38)%],difficulty in respiratory was[(1.04±0.37)s vs( 1.72±0.45)s] and motor ability was [(387.32±52.07)m vs (318.35±61.52)m] in thoracoscope group and open heart group (P<0.05).At the six month after surgery,body mass index was[(27.19±2.18)kg/m2 vs (20.90±2.35)kg/m2] in thoracoscope group and open heart group(P<0.05);At the 12 month after operation,there was no significant difierence in BODE index between the two groups(P>0.05).Conclusions Video-thoracoscope in treating COPD with pneumothorax can remarkably improve the quality of life early after surgery.

Objective To explore the effect of gastrin_(17) on E cadherin/?-catenin complex,a down- stream effector of FAK pathway,in colonic carcinoma cell line CoLo320WT.Methods pCR3.1/GR plasmid expressing gastrin receptor CCK 2R was transfected into colonic carcinoma cell line CoLo320 by Lipofectamine~(TM) 2000 and expressing stably CCK 2R clones was screened by G418.The expression levels of gastrin receptor of Coi.o320 and the transfected cell line Colo320WT were assayed by RT PCR. CoLo320WT cells were treated by 10~(-8)mmol/L gastrin_(17) at distinct time points (0 hr,1 hr,6 hr,12 hr, 24 hr,48 hr),whilst treated by 10_(-6) mmol/L L365,260 (gastrin_(17) receptor blocker) simultaneously for 30 minutes and then treated by gastrin_(17) again for 12 hr.Expression levels of phosphorylated FAK Tyr397 and total FAK in CoLo320WT under gastrin_(17)intervention were detected hy Western blot.Ex- pression levels of E-cadherin and?-catenin complex in TX-100 solution fraction and TX-100 insolution fraction of CoLo320WT cells were detected by coimmunoprecipitation and Western blot.Distribution of E-cadherin and?-catenin in CoLoWT320 were observed by immunocytochemistry.Results Phosphoryla- ted FAK Tyr397 expression in CoLo320WT cells increased in time dependent fashion under gastrin_(17) intervention and peaked at 12 hour after intervention,while decreased by L365,260 inhibition.But gas trine_(17) had no effect on total FAK in CoLo320WT cells.Expresion levels of E-cadherin and?-catenin com- plex in TX-100 solution fraction were decreased apparently,but increased again after L365,260 block- ing.On the contrary,the expression levels of E-cadherin and?-eatenin complex in TX-100 solution frac tion differed from that in TX-100 solution.Cytoehemistry observation had revealed that E-cadherin and?-catenin transferred from cell membranes into cndochylemas,nuclei and cytoskeleton under gastrin_(17) in- tervention.Conclusions Gastrin_(17)affected significantly the distribution of E cadherin/?-catenin complex in CoLo320WT by phosphorating FAK Tyr397 and activating FAK pathway when it bound to its recep- tor CCK-2,therefore promoted invasion and metastasis of CoLo320WT.

Objective To compare and the advantages and disadvantages of 3 methods of bone grafting in the posterior treatment of thoracolumbar burst fracture.Methods A retrospective analysis was conducted of 258 thoracolumbar burst fractures treated with posterior short-segment fixation from March 2013 to March 2015 at Orthopedic Department One,Foshan Hospital of Traditional Chinese Medicine.Of them,87 were treated with transpedicular bone grafting (group A),87 with laminar and intertransverse process bone grafting (group B) and 84 with small joint turnover plus bone grafting (group C).The 3 groups were compared in terms of cobb angle,loss of correction,bony fusion,internal fixation failure,and Oswestry disability index (ODI).Results The 3 groups were comparable due to insignificant differences in the preoperative general data between them (P ＞ 0.05).The cobb angles in the 3 groups at one week after operation (4.9° ± 1.0°,4.8° ± 0.6° and 4.8° ± 0.6°) and at the final follow-up (6.1 o ± 1.5°,14.5° ± 3.7° and 15.3° ± 4.1 °) were significantly smaller than those before operation (27.5° ± 4.9°,27.6° ± 4.6° and 27.6° ± 4.2°) (P ＜ 0.05).The cobb angles in groups B and C at the final follow-up were significantly larger than those at one week after operation (P ＜0.05).At the final follow-up,both the cob angles and the loss of kyphoplasty correction in groups B and C were significantly larger than in group A (P ＜ 0.05).The fusion rate in group A (100％) was significantly larger than in group B (80.5％) and C (76.2％).There were no significant differences between the 3 groups in the rate of internal fixation failure (0,1.1％ and 2.4％) (x2 =2.108,P=0.348).The ODI for the 3 groups at 6 months after operation (28.5 ± 4.1,28.7 ± 3.9 and 28.8 ± 3.7) and at the final follow-up (10.7 ± 2.6,11.0 ± 2.7 and 11.4 ± 3.1) were all significantly lower than the preoperative values (94.3 ± 0.7,94.4 ± 0.9 and 94.4 ± 0.8) (P ＜ 0.001).In all the patients,the ODI at the final follow-up was significantly lower than that at 6 months after operation(P ＜ 0.001).Conclusions In the treatment of thoracolumbar burst fractures,all the posterior approach plus transpedicular bone grafting,posterolateral bone grafting and reversed bone grafting plus short segmental internal fixation can effectively restore vertebral height and result in a high rate of fusion.Although the latter 2 methods of bone grafting are effective,they may be disadvantageous in leading to long-term loss of vertebral height and kyphosis correction.

OBJECTIVETo compare the inter- and intra-observer reliability of the GATA and SMU classification systems for spinal tuberculosis and assess the clinical value of SMU classification.

METHODSOne hundred patients with spinal tuberculosis treated in our hospital from January 2004 to December 2011 were randomly selected for analysis, including 54 males and 46 females with a mean age of 45 years (range, 16-68 years). All the patients had X-ray, CT and MRI examinations. Five observers experienced in spinal tuberculosis independently assigned the classification using the GATA and SMU classification systems, and the assignment was repeated 3 months later to test its reproducibility. Kappa value was used to determine the intra- and inter-observer reliability.

RESULTSFor GATA and SMU classification systems, the inter-observer percentage of agreement averaged (59.9∓4.84)% (κ=0.412∓0.058) and (81.6∓6.06)% (κ=0.753∓0.068), and the intra-observer percentage of agreement was (75.6∓5.27)% (κ=0.624∓0.078) and (89.8∓2.28)% (κ=0.862∓0.037), respectively.

CONCLUSIONThe SMU classification system of spinal tuberculosis has a higher inter-observer and intra-observer reliability than the GATA classification system, but its clinical value needs to be further tested in future clinical trials.
