BACKGROUND:The posterior lumbar interbody fusion is one of the effective methods for the treatment of lumbar and sacral spine diseases. Most surgeons fix the cage by compressing the disc space in order to keep stability and prevent dislodgement. However, some surgeons think that the non-compression technique does favor for increasing of the disc and foraminal height and thus improving the clinical outcomes, and does not increase the risk of fusion shift.
OBJECTIVE:To compare the effects in fixing the cage by the compression and non-compression techniques on posterior lumbar interbody fusion.
METHODS:Data of 64 patients with single-segment lumbar degeneration undergoing posterior lumbar interbody fusion between August 2009 and June 2014 were retrospectively analyzed. Fusion device was fixed according to compression of intervertebral space. These patients were divided into compression group (n=30) and non-compression group (n=34).
RESULTS AND CONCLUSION:(1) Curative effects:Lumbar and leg pain visual analogue score,
Oswestry disability index, SF-36 score and the height of intervertebral space, intervertebral foramen height and lumbar lordosis were significantly improved postoperatively in each group compared with preoperatively (P<0.05). The intervertebral space, intervertebral foramen height and lumbar lordosis were significantly better in the non-compression group than in the compression group (P<0.05). (2) Lumbar fusion rate:No significant difference in lumbar fusion rate was detected 6 and 12 months after surgery and during final fol ow-up (P>0.05). (3) Correlation analysis:The increase of the intervertebral space and the height of the intervertebral foramen were not significantly correlated with the improvement of the clinical curative effect (P>0.05). (4) Test results demonstrated that outcomes of the compression technique to fix the cage are equivalent to the non-compression in posterior lumbar interbody fusion. Non-compression is advantageous to increase the intervertebral space and the height of the intervertebral foramen. Both of them are conducive to the recovery of lumbar lordosis, but are not correlated with the increase in clinical curative effect.

OBJECTIVE To investigate the distribution of Pseudomonas aeruginosa and its antibiotic resistance in(emergency) intensive care unit(EICU) patients with lower respiratory infections.METHODS The data of the pathogens isolated in sputum from the 25 patients with lower respiratory infections admitted to EICU from(Aug) 2005 to Feb 2006 were collected and analyzed.RESULTS Eighty-one bacteria strains were found in these 25 EICU cases.The Gram-negative bacteria were the main pathogens of infection(43.2%),after them were Gram-positive bacteria(32.1%),and fungi(24.7%).The percentage of P.aeruginosa infection was 13.6% of all(patients).The antibiotic resistance for P.aeruginosa was found to the antibiotics,such as cefotaxime,gentamicin,(SMZ-TMP),minocycline,levofloxacin,and gatifloxacin.CONCLUSIONS The P.aeruginosa infection and its(antibiotic) resistance should be paid more attention in the treatment of the lower respiratory infection patients in EICU.

METHODS:The utilization of pe-diatric prescription drugs in inpatient department of our hospital during 2008 to 2014 was analyzed in respects of number,consump-tion sum,DDDs,etc. RESULTS:The consumption sum of antimicrobial drugs increased from 657 000 yuan in 2008 to 1 453 000 yuan in 2014. The consumption sum of creatine phosphate sodium increased from 384 000 yuan in 2012 to 889 000 yuan in 2014. The consumption sum of Lysine hydrochloride and sodium chloride injection entered the top 5 in 2014,reaching 205 000 yuan. The consumption sum of essential medicines changed greatly due to varieties. Top 5 antimicrobial drugs in the list of DDDs mainly wereβ-lactam,showing a descreasing trend on the whole. CONCLUSIONS:There are some problems in use of part drugs. It is need to strengthen propaganda and intervention of rational drug use.

BACKGROUND:Posterior cervical open-door expansive laminoplasty is one of the simple and effective methods to treat cervical spinal diseases, has satisfactory results but low complications. However, the imbalance of sagittal plan, loss of lordosis or axial pain is often reported recently. OBJECTVE:To analyze the correlation between cervical sagittal alignment and clinical outcomes after laminoplasty. METHODS:Between January 2011 and June 2015, 122 cases of cervical spinal disease, who were treated with open-door expansive laminoplasty with mini-titanium plate, were retrospectively analyzed. Clinical outcomes were evaluated by Japanese Orthopaedic Association, Neck Disability Index and Visual Analogue Scale. Radiographic results were assessed by C2-7 Cobb angle, C2-7 sagittal vertical axis and C7 slope. The correlation between sagittal alignment and clinical outcomes were analyzed. RESULTS AND CONCLUSION:(1) Al patients were fol owed up for 7-32 months. (2) Japanese Orthopaedic Association, Neck Disability Index and Visual Analogue Scale scores were improved in the final fol ow-up (al P<0.001). No significant difference in upper limb Visual Analogue Scale scores was determined (P=0.142). In the final fol ow-up, C2-7 sagittal vertical axis increased (P=0.036), but neither the C2-7 Cobb angle nor the C7 slope significantly changed (P=0.092, P=0.184). (3) There were no correlations between sagittal alignment parameters (C2-7 Cobb angle, C2-7 sagittal vertical axis and C7 slope) and clinical outcomes (Japanese Orthopaedic Association, Neck Disability Index and Visual Analogue Scale) (al P>0.05). (4) These findings indicated that posterior cervical open-door expansive laminoplasty with mini-titanium plate can significantly improve the neurological function of patients. However, there is no correlation between cervical sagittal alignment and clinical outcomes.

Aim To study the effects of Quercetin on the angioge ne sis and cultured human vascular endothelial cells (HUVEC).Methods In vivo, the effects of Quercetin on angiogenesis induced by vascular en dothelial growth factor (VEGF) and basic fibroblast growth factor(bFGF), were observ ed by chorioallantioic membrane (CAM) test. The effects of quercetin on proliferation of human vascular endothelial cells (HUVEC) were assessed by MTT assay. The effects of Quercetin on cell cycle of HUCEC were observed by flow cytometer (FCM ).Results The angiogenesis induced by VEGF in CAM was strongly inhibited by Quercetin with 0.1, 0.05 and 0.025 mmol?L -1; The angiogen esis induced by bFGF in CAM. was strongly inhibited by Quercetin with 0.1 and 0 .05 mmol?L -1. Quercetin markedly inhibited the proliferation of HUVEC with 240,120,60 and 30 ?mol?L -1. The inhibition rate was 67.0%,58.1% ,39.7% and 20.7% respectively. Quercetin at the concentration of 240 ?mol? L -1 and 120 ?mol?L -1 resulted in S,G 2 arrest of HUVEC. Conclusion Quercetin has substantial inhibitory effects on angiogenesi s induced by VEGF and bFGF, and on proliferation of HUVEC.

BACKGROUND: The authors have studied the porosity, pore size, mechanical strength, in vitro biological activity,ectopic osteogenic activity of porous biphasic calcium phosphate enhanced by recombinant bone morphogenetic protein-2/silk fibroin sustained-release microsphere (BCP/rBMP-2/SF). However, further investigation on the osteogenic ability of the composite bone graft material is warranted based on a reliable animal model, which will provide experimental data for the clinical application of the composite material in the spinal fusion.OBJECTIVE: To investigate the osteogenic efficacy of BCP/rBMP-2/SF in a sheep lumbar interbody fusion model.METHODS: Sixteen healthy adult sheep were divided into two groups randomly. All sheep were operated on the left extraperitoneal approach and intervertebral discs of L1/2, L3/4, and L5/6 were exposed respectively. Three of the following four materials were randomly implanted into the L1/2, L3/4, and L5/6 of each animal: autologous iliac, BCP/rhBMP-2/SF,BCP/rhBMP-2 or BCP/SF.RESULTS AND CONCLUSION: The group of BCP/SF/rhBMP-2 achieved a similar fusion rate compared with the group of autologous iliac at 12 and 24 weeks after operation, and they were significantly better than the other two groups. These findings indicate that the novel new artificial bone, BCP/rhBMP-2/SF, can obtain similar lumbar fusion results compared with the autologous iliac. It is expected to be applied to clinical practice in the future by further improving its properties.
