Of them, 5 patients added to anterior instrumentation.Results45 patients had been followed up for 12 to 40 months.The back pain of 40 cases were relieved within 5 weeks after operation, erythrocyte sedimentation rate decreased 3 weeks after operation. 38 patients who involved in kyphosis decreased their kyphosis mostly and only one patient lost 3 degrees in follow-up.15 patients who involved in neurological deficits improved one or two grades (Frankel). Grafts fused in 44 patients and there were no recurrent in follow-up.Conclusions Operative treatment is efficacious to multi-level body spine tuberculosis.

I uptake of thyroid and color Doppler flow imaging (CDFI) of superior thyroid artery (STA) were performed in 20 patients with Graves′ disease (GD) and 19 patients with other causes of hyperthyroidism. Maximum velocity and diameter of STA in patients with GD were much higher than those in non-GD group. CDFI of STA seems to be a useful tool in differential diagnosis of hyperthyoidism.

ObjectiveTo explore the effect of carotid artery sympathetic net exfoliation combined with hyperbaric oxygen therapy on athetosic type cerebral palsy (CP).Methods46 CP children (athetosic type) were divided into the treatment group (n=25) and control group (n=21). All cases of two groups were treated with carotid artery sympathetic net exfoliation as well as children of the treatment group were added with drug and hyperbaric oxygen therapy. Therapeutic effect of two groups was compared.ResultsOne week after operation, the effect rate was 66.67% in control group and 64% in treatment group with no significant difference between two groups. 3 months after operation, the effect rate of the treatment group increased to 96.00%, but that of the control group was not changed, there was a significant difference between two groups (P<0.05).ConclusionCarotid artery sympathetic nerve net exfoliation can improve the symptoms of athetosic type CP children, if combined with hyperbaric oxygen therapy, the curative effect will be further improved.

Background Surgical induced astigmatism induced by a 5.5mm of superior scleral tunnel incision is a key cause of influencing vision outcome in the high myopic eyes after implantation of Artisan phakic intraocular lens(IOL).Objective This study was to evaluate the surgical induced astigmatism through a 5.5mm superior scleral tunnel incision during the implantation of Artisan phakic IOL.Methods This was a case observational study.The clinical data of 202 eyes of 111 patients with Artisan IOL implantation for high myopia from October 2004 through October 2008 was collected.The patients were followed-up for 12 months.The uncorrected visual acuity(UCVA),best spectacle-corrected visual acuity(BCVA),spherical equivalent(SE),cylinder equivalent(CE) and cylinder axis were examined before surgery and postoperative 1,3,6,12 months.The patients were divided into with rule group and against rule group according to the cylinder axis.Surgery-induced astigmatism value was calculated using Holladay vector analysis formula.This clinical trial was approved by the Ethics Committee of Guangdong General Hospital.Written informed consent was obtained from each patient prior to the surgery.Results The UCVA of 195 eyes(94.1%) was 0.5 or better in postoperative 12 months,and that of 172 eyes(85.1%) showed the improvement of BCVA during the follow-up duration.The mean CE values were reduced in 1,3,6,12 months after surgery in comparison with before surgery(t=-4.30,P=0.00;t=-2.27,P=0.01;t=-2.04,P=0.04;t=-2.79,P=0.01).Vector analysis of total surgically induced astigmatism revealed that the mean incision-induced astigmatism value was +1.94D,+2.26D,+2.29D,+2.25D at 171°,170°,181°,175° in 1,3,6,12 months after surgery.The surgery-induced astigmatism was(+1.97±1.84)D,(+2.25±1.75)D,(+2.27±1.76)D,(+2.24±1.75)D in with rule group at postoperative 1,3,6,12 months respectively;while those in against rule group was(+1.75±1.88)D,(+2.35±1.74)D,(+2.38±1.76)D,(+2.34±1.74)D respectively.No significant differences were found between the two groups(t=0.54,-0.29,-0.27,-0.29;P=0.59,0.78,0.79,0.78).Conclusion Implantation of Artisan IOL is an effective approach for correction of high myopia.A 5.5mm superior scleral tunnel incision in operation induces a +2.25D astigmatism at 175° meridian.

Our previous results have demonstrated that insulin reduces myocardial ischemia/reperfusion (MI/R) injury and increases the postischemic myocardial functions via activating the cellular survival signaling, i.e., phosphatidylinositol 3-kinase (PI3-K)-Akt-endothelial nitric oxide synthase (eNOS)-nitric oxide (NO) cascade. However, it remains largely controversial whether c-Jun NH2-terminal kinase (JNK) is involved in the effects of insulin on MI/R injury. Therefore, the aims of the present study were to investigate the role of JNK, especially the cross-talk between JNK and previously expatiated Akt signaling, in the protective effect of insulin on I/R myocardium. Isolated hearts from adult Sprague-Dawley rats were subjected to 30 min of regional ischemia and followed by 2 or 4 h of reperfusion (n=6). The hearts were pretreated with PI3-K inhibitor LY294002, or phosphorylated-JNK inhibitor SP600125, respectively, then perfused retrogradely with insulin, and the mechanical functions of hearts, including the heart rate (HR), left ventricular developed pressure (LVDP) and instantaneous first derivation of left ventricular pressure (+/-LVdp/dt(max)) were measured. At the end of reperfusion, the infarct size (IS) and apoptotic index (AI) were examined. MI/R caused significant cardiac dysfunction and myocardial apoptosis (strong TUNEL-positive staining). Compared with the control group, insulin treatment in MI/R rats exerted protective effects as evidenced by reduced myocardial IS [(28.9 +/- 2.0)% vs (45.0 +/- 4.0) %, n=6, P<0.01], inhibited cardiomyocyte apoptosis [decreased AI: (16.0 +/- 0.7) % vs (27.6 +/- 1.3) %, n=6, P<0.01] and improved recovery of cardiac systolic/diastolic function (including LVDP and +/-LVdp/dt(max)) at the end of reperfusion. Moreover, insulin resulted in 1.7-fold and 1.5-fold increases in Akt and JNK phosphorylation in I/R myocardium, respectively (n=6, P<0.05). Inhibition of Akt activation with LY294002 abolished, and inhibition of JNK activation with SP600125 enhanced the cardioprotection by insulin, respectively. And the abolishment by LY294002 could be partly converted by SP600125 pretreatment. In addition, SP600125 also decreased the Akt phosphorylation (n=6, P<0.05). These results demonstrate that insulin simultaneously activates both Akt and JNK, and the latter further increases the phosphorylation of Akt which attenuates MI/R injury and improves heart function; this cross-talk between Akt and JNK in the insulin signaling is involved in insulin-induced cardioprotective effect.
