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 effects of aerosol inhalation of ambroxol combined with gentamicin on postopera-tive related indexes of esophageal cancer patients. METHODS:60 patients underwent esophageal cancer operation were retrospec-tive analyzed and divided into control group(30 cases)and observation group(30 cases)according to drug use. Three days before surgery,control group was given 5% Glucose injection 250 mL intravenously,twice a day;observation group was given Ambrox-ol hydrochloride injection 50 mL added into 5% Glucose injection 250 mL intravenously,twice a day. After operation,both groups were given anti-inflammatory and analgesic drugs. Control group was additionally given aerosol inhalation of Gentamicin sulfate in-jection 80000 units added into 0.9% Sodium chloride injection 20 mL,4 times a day. Observation group was additionally given aerosol inhalation of Ambroxol hydrochloride injection 10 mL added into 0.9% Sodium chloride injection 20 mL,4 times a day, on the basis of control group. Both groups were treated for 5 days. The occurrence of postoperative pulmonary complications were compared between 2 groups. The levels of CRP,TNF-α,PaO2,SaO2,oxygenation index (PaO2/FiO2),the occurrence of ADR were observed before and after operation. RESULTS:The total incidence of postoperative pulmonary complications in observation group was significantly lower than control group,with statistical significance(P<0.05). Before operation,there was no statistical significance in the levels of CRP,TNF-α,PaO2,SaO2 and PaO2/FiO2 between 2 groups(P>0.05). After operation,the levels of CRP and TNF-α in 2 groups were significantly lower than before operation;the observation group was significantly lower than the control group. PaO2,SaO2 and PaO2/FiO2 of 2 groups were sig-nificantly higher than before operation;the observation group was significantly higher than the control group,with statistical significance (P<0.05). No obvious ADR was found in 2groups during medication. CONCLUSIONS:The aerosol inhalation of ambroxol combined with gentamicin can reduce postopera-tive inflammatory factors of esophageal cancer patients,and promotes the recovery of respiratory function without increasing the in-cidence of ADR.

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.

Purpose To explore the value of 128-slice dual source CT (DSCT) three-dimensional post-processing techniques in the diagnosis of acute aortic dissection (AAD). Materials and Methods All image data of 116 patients with AAD who underwent conventional and enhanced DSCT scan by dual-energy scanning technology were retrospectively analyzed, and the multi-planar reconstruction (MPR), volume rendering (VR) and maximum intensity projection (MIP) were conducted in the workstation. Taking digital subtraction angiography (DSA) as the diagnostic gold standard, we analyzed the imaging manifestation of the original and 3D-reconstruction images and evaluated the specificity and the sensitivity of diagnostic accuracy and the image quality. Results The diagnostic accuracy of conventional scan was 37.1%(43/116). The display rates of MPR for initial break, intimal flap and true and false lumen were 93.1%, 100.0%and 100.0%, respectively. The display rates of VR and MIP for the initial break were 33.62%and 6.90%, respectively, which was both lower than that of MPR. The display rate of MIP for the true and false lumen was 23.28%. The overall display capability of MPR was significantly better than that of VR and MIP (P<0.01), and the display capability of VR was better than that of MIP (P<0.01). The sensitivity and specificity of enhanced DSCT in the diagnosis of AAD were both 100.0%. Conclusion DSCT has a fast and reliable diagnostic value on AAD. Conventional CT signs should be highly valued in the evaluation of chest or abdominal pain; and a thin layer of MPR and VR should be chosen in the three-dimensional reconstruction;whilst MIP reconstruction may be unnecessary for AAD.

Objective To investigate the effets of three mood stabilizers on ouabain?induced ERK1/2 phosphorylation in astrocytes. Methods As?trocytes were treated with different agents and divided into different groups accordingly,namely,the control group with saline,the group with oua?bain,the group with mood stabilizers(lithium carbonate,carbamazepine,sodium valproate)and the group with ouabain+mood stabilizers. The phosphorylation of ERK1/2 in each group was analyzed by Western blot. Results Compared with saline and mood stabilizer groups,the phosphoryla?tion of ERK1/2 was increased in the ouabain group,with statistical significance(P<0.05). There was no significant difference in ERK1/2 phosphoryla?tion between the group with ouabain+mood stabilizers and the control or mood stabilizer group. Conclusion The three kinds of mood stabilizers can inhibit ouabain?induced ERK1/2 phosphorylation in astrocytes.
