RESUMO
Objective To investigate the therapeutic effect of 3D curvature traction on neck-type cervical spondylosis.Methods Totally 100 neck-type cervical spondylosis patients were divided randomly and equally into an observation group and a control group.The observation group underwent the treatment by 3D curvature traction combined with intermediate frequency therapy,and the control group went through the treatment by cupping and intermediate frequency therapy.Evaluation was carried out on neck pain,tenderness and cervical mobility before and after the treatment.Results The recovery rate was 88％ in the observation group,which was significantly higher than that (40％) in the control group (P=0.007).The total effective rate was 100％ in the observation group,which was obviously higher than that (88％) in the control group (P=0.029).The score differences for pain and cervical mobility before and after the treatment were 4.96±0.36 and 1.67±0.73 respectively in the observation group,which were statistically different from the score differences for pain (3.38±0.80) and cervical mobility (0.88±0.76) in the control group (P＜0.05).Conclusion 3D curvature traction gains high clinical effect when used to treat neck-type cervical spondylosis.

RESUMO
<p><b>OBJECTIVE</b>The main objective of this study is to assess the the effect of simvastatin (sim) on myocardial no-reflow (NR) and explore the possible potential mechanisms.</p><p><b>METHODS</b>Adult male Wistar rats were randomized into sham group (n = 12), I/R (90 min ischemia via coronary ligation/120 min reperfusion, n = 18) and I/R plus sim group (20 mgxkg(-1)xd(-1) sim pretreated via gavage beginning 3 days before I/R, n = 18). After reperfusion, area at risk/area of left ventricular (RA/LVA), area of NR, determined by the area not perfused by thioflavin-S/area at risk (NA/RA) and area of myocardial infarction/area at risk (MIA/RA) were measured. Myocardium homogenate was used to determine the activity of eNOS, iNOS and MPO, and the content of NO and MDA. Myocardial immunohistochemistry was performed to determine the positive index of NF-kappaB p65 in cardiomyocytes and arteriole.</p><p><b>RESULTS</b>The NR and myocardial infarction areas in I/R plus sim group were significantly smaller than those in I/R group (34.10 +/- 7.05 vs. 52.09 +/- 6.89, 78.80 +/- 7.60 vs. 90.13 +/- 5.72, each P < 0.05) while the ischemia area was similar between the 2 groups (P > 0.05). The myocardial activities of iNOS and MPO, the contents of NO and MDA were significantly lower while eNOS activity was significantly higher in I/R plus sim group than those in I/R group (5.02 +/- 1.64 vs. 9.19 +/- 2.89, 586.21 +/- 126.97 vs. 744.49 +/- 137.53, 257.72 +/- 93.43 vs. 384.10 +/- 40.68, 72.10 +/- 18.56 vs. 111.84 +/- 38.58, 7.08 +/- 1.74 vs. 3.72 +/- 0.98, all P < 0.05). The positive index of NF-kappaB p65 in cardiocytes and arteriole at left ventricular wall near the area of myocardial infarction was significantly lower in I/R plus sim group than that in I/R group (21.59 +/- 10.5 vs. 34.32 +/- 9.55, 27.27 +/- 13.19 vs. 44.91 +/- 15.06, each P < 0.05).</p><p><b>CONCLUSION</b>Simvastatin could improve myocardial NR after ischemia-reperfusion by attenuating endothelial dysfunction and inhibiting inflammation and neutrophil activation.</p>
