OBJECTIVETo study the biomechanical relationship between iliac rotation displacement and L(4,5) disc degeneration, and to provide clinical evidences for the prevention and treatment of L(4,5) disc degeneration and herniation.

METHODSFrom March 2012 to February 2014,68 patients with lumbar disc herniation combined with sacroiliac joint disorders were selected. Among them, 42 patients with L(4,5) disc herniation combined with sacroiliac joint disorders included 22 males and 20 females, ranging in age from 19 to 63 years old, with an average of (51.78 +/- 20.18) years old, and the duration of the disease ranged from 1 to 126 months with an average of (11.18 +/- 9.23) months. Twenty-six patients with L5S1 disc herniation combined with sacroiliac joint disorders included 11 males and 15 females, ranging in age from18 to 65 years old with an average of (45.53 +/- 27.23) years old, and the duration of the disease ranged from 0.5 to 103 months with an average of (11.99 +/- 12.56) months. Sixty-eight anteroposterior lumbar radiographs, 68 lateral lumbar radiographs,and 68 pelvic plain films were taken. The degree of lumbar scoliosis, pelvic tilt,and disc thickness were measured. The correlation between pelvic tilt and lumbar scoliosis ,lumbar scoliosis and disc thickness were studied by using linear and regression methods. The hiomechanical analysis was performed.

RESULTSThere was a positive correlation between pelvic tilt and lumbar scoliosis in patients with L(4,5) disk herniation (R=0.49, P=0.00). There was a causal relationship and good linear proportional relationship (Y=3.05+1.07X, P=0.00) in the two variables. There was a negative correlation between lumbar scoliosis and intervertebral space in male patients with L (4,5) disk herniation (R = -0.50, P=0.01). There was a causal relationship and good linear proportional relationship in the two variables (Y=13.09-0.27X, P=0.02). But there was a positive correlation between lumbar scoliosis and intervertebral space in male patients with L5S1 disk herniation (R=0.46, P=0.04).

CONCLUSIONIliac rotational displacement are closely related with L(4,5) disc degeneration and herniation in biomechanics. A new concepts and therapeutic approach is provided for clinical treatment of chronic and refractory herniation of L(4,5) disc in patients

Objective To evaluate the feasibility of monitoring the gene expression of VEGF165 via the diglycylcysteine (GGC) reporter gene system by reporter probe of 99Tcm-GH. Methods DNA fragments encoding GGC binding motifs were prepared by PCR and positioned at the C end of VEGF165 gene after the linearization of pcDNA3-VEGF165 plasmid. A replication-defective adenovirus vector Ad5-VEGF165GGC motif-internal ribosomal entry site(IRES) -enhanced green fluorescent protein (EGFP) (Ad5-VIE)was constructed, with a cytomegalovirus (CMV) early promoter driving the expression of VEGF165 gene,GGC motif and EGFP, under the aid of an IRFS. A replication-defective adenovirus carrying the Ad5-EGFP was used as the control. Mensenchymal stem cells (MSC) were infected with the recombinant adenovirus at a multiplicity of infection (MOI) from 0 to 100 infectious units (0,10,25,50,100). The cellular uptake of 99Tcm-GH in infected MSC were then studied at 30, 60, 90 and 120 min. VEGF165 was detected by quantitative reverse transcriptase real-time PCR (RT-PCR), Western-blot, and immunohistochemisty. EGFP was observed by RT-PCR and fluorescence microscopy. The correlation analysis was studied between the cellular uptake of 99Tcm-GH and the expression of VEGF165. SPSS 13.0 was applied for statistical analysis. Independent samples t-test, q-test and Pearson correlation coefficient were used. Results After infected with different viral titer of Ad-VIE, the cellular uptake of 99Tcm-GH increased with the increasing virus titer(r2 =0.86, P ＜0.05), with the peak rate (7.94 ±0.75) % at MOI = 100. In time-dependent uptake study, the cellular uptake rates increased rapidly with the time extension, and the highest uptake occurred at 120 min with the peak uptake rate (7.72 ±0.22)%. The uptake rates of 99Tcm-GH in Ad5-VIE-infected cells were significantly higher than those of Ad5 -EGFP-transfected cells at all time points (t = 15.10- 54.92, all P ＜0.05). The VEGF165 and EGFP mRNA levels increased with increasing virus titer, and the VEGF165 mRNA correlated well with the EGFP mRNA(r2 = 0. 99, P ＜ 0.05). After infected with different MOI of Ad5-VIE, good relationship was found between the cellular uptake of 99Tcm-GH and the expression of VEGF165protein in MSC(r2 =0.90, P ＜0.05). Inmunohistochemisty showed VEGF165 protein expressed obviously at Ad5-VIE-infected MSC, and the EGFP was observed by fluorescence microscopy. Conclusions The cellular uptake of 99Tcm-GH in Ad5-VIE-infected MSC are well correlated with the expression of VEGF165 in vitro. The expression of therapeutic gene VEGF165 can be monitored by the GGC peptide expression.

Objective To investigate the effects of ISO-1, a selective MIF tautomerase activity inhibitor, on liver metastasis in a BALB/c mouse model of colonic cancer. Methods Micmporous migration assay was used to determine the effect of ISO-1 on the invasion abilities of CT26 cells. Orthotopic transplantation of fresh colonic tumor fragments into the hernial sac of cecum was used in a BALB/c mouse model of eolorectal cancer. Thirty mouse models were divided into three groups and treated respectively with ISO-1 (0. 2 ml, 20 mg/kg), 5% DMSO and NS ( normal sodium) twice a week, iutraperitoneally. After 4 weeks, mice were sacrificed and the whole livers were made into serial slices to detect the occurrence of liver metastasis. Serum MIF tautomerase activities were measured using L-dopachrome methyl ester, ELISA was used to test serum VEGF concentrations. Immunohistochemical staining of CD31 was used for comparing microvascular density (MVD) of tumor tissues. Results 100 μmol/L ISO-1 treatment for 24 hours significantly reduced the average number of the cells penetrating polycarbonates, ( 151 ± 19 ) vs. ( 178 ± 9 ), P<0. 01. Serum MIF tautomerase activities were significantly inhibited after ISO-1 treatment (51% vs. 81%, P <0. 01 ). Compared with DMSO and NS treatment, ISO-1 decreased the occurrence of liver metastasis ( 10% ,60% and 70% ,respectively;x2 = 8. 30, P < 0. 05 ). Also ISO-1 decreased serum VEGF levels ( 15 ± 7 ) pg/ml, ( 63 ± 11 ) pg/ml and ( 67 ± 8 ) pg/ml, respectively; P < 0. 01 and the MVD of tumor tissues (17±4) ,(36±7) and( 38±5) ,respectively; P<0. 01. Conclusion In vitro ISO-1 inhibits the invasion ability of CT26 cells. In vivo ISO-1 reduces the occurrence of liver metastasis, possibly by a mechanism of inhibiting MIF tautomerase activities, down-regulating the expression of VEGF and reducing MVD.

OBJECTIVETo observe the supplementary analgesic effect of electroacupuncture and its influence on the maintenance of anesthesia and the speed of recovery of patients undergoing craniotomy.

METHODSEighty cases of supratentorial tumor resection were randomly divided into group A and group S, 40 cases in each group. All the patients were anesthetized with 2% Sevoflurane. The patients in group A received electroacupuncture at Hegu (LI 4) and Waiguan (TE 5), Jinmen (BL 63) and Taichong (LR 3), Zusanli (ST 36) and Qiuxu (GB 40) from anesthesia beginning to the end of operation, and in group S without electroacupuncture. The end-tidal Sevoflurane concentration, minimum alveolar concentration (MAC), bispectral index (BIS) and the information during anesthesia recovery stage were recorded, respectively.

RESULTSThe end-tidal concentration and MAC of Sevoflurane in group A at all times were significant lower than those in group S (P<0.05, P<0.01) with a Sevoflurane saving of 9.62% on average. The BIS in group A during a few phases were higher than that in group S (all P<0.05). During anesthesia recovery stage, the time of each phase in group A was significantly shorter than that in group S (all P<0.01). No dysphoria and one case with nausea and vomiting were shown in group A, but in group S, 2 patients had dysphoria and 3 patients had nausea and vomiting.

CONCLUSIONElectroacupuncture combined with Sevoflurane anesthesia can decrease the dosage of Sevoflurane, shorten the recovery time of anesthesia and improve the quality of anesthesia recovery of the patients undergoing resection of supratentorial tumor.
