ABSTRACT
OBJECTIVE@#Quantitative assessment of white blood flow in semi-oval center of patients with delayed neuropathological sequelae (DNS) after carbon monoxide poisoning treated with acupuncture combined with hyperbaric oxygen (HBO) based on magnetic resonance multi-inversion time arterial spin labeling imaging (mTI-ASL), and to evaluate its efficacy indirectly.@*METHODS@#Twenty-six patients with clinically diagnosed DNS were randomly divided into an observation group (13 cases) and a control group (13 cases). The conventional therapy combined with HBO were given in the control group. In the observation group,on the base of the treatment, acupuncture was applied, the main acupoints were Shuigou (GV 26), Neiguan (PC 6), Baihui (GV 20), Shangxing (GV 23), Yintang (GV 29), Sanyinjiao (SP 6) on the affected side, Sishencong (EX-HN 1), Fenglong (ST 40), Lianquan (CV 23) and Jinjin (EX-HN12) for slurred speech, Jianyu (LI 15), Waiguan (TE 5) and Shousanli (LI 10) for upper limb pain, Huantiao (GB 30), Yanglingquan (GB 34), Yinlingquan (SP 9) for lower limb pain, the treatment was given once every day, 5 days as one course, with an interval of 2 days between the course. The treatment for 6 courses was required. The conventional head MR scan, mTI-ASL and diffusion tensor imaging (DTI) scans before and 1 week after treatment were adopted, Matlab (R2014b), Mricron and Syngo.via software were adopted to measure the cerebral blood flow (CBF) and anisotropy (FA) values of the semi-oval center. The correlation between the parameters was evaluated by Pearson method. And the simple intelligent mental state examination scale (MMSE) was uesd to assess cognitive function.@*RESULTS@#After treatment, the CBF, MMSE scores in both groups and FA values in the observation group were higher than those before treatment (<0.05). After treatment, the CBF, FA and MMSE scores in the observation group were significantly higher than those in the control group (<0.05). There was a positive correlation between CBF, FA and MMSE scores (<0.05), and the correlation between CBF and MMSE was the best ( =0.822).@*CONCLUSION@#Acupuncture combined with hyperbaric oxygen can significantly improved early white matter hypoperfusion and improved cognitive function score in patients with DNS. The curative effect is better than that of hyperbaric oxygen therapy alone. The mTI-ASL imaging can quantitatively evaluate its curative effect.

<p><b>OBJECTIVE</b>To evaluate the association between left coronary artery stenosis degree and myocardial perfusion by 64 multi-slice CT.</p><p><b>METHODS</b>A total of 223 patients underwent 64 multi-slice CT coronary artery images (CTA) were included and divided into normal group (91 cases), mild stenosis group (72 cases), moderate stenosis group (36 cases) and severe stenosis group (24 cases). Myocardial density was measured at apical, septal and lateral segments. Myocardial density in infarcted segments was compared to non-infarct segments in 11 patients with old myocardial infarction (all from severe stenosis group).</p><p><b>RESULTS</b>Myocardial density was significantly lower at apical segments [(55.8 ± 21.4) HU vs. (75.3 ± 7.5) HU], at septal segment [(87.8 ± 3.3) HU vs. (98.2 ± 5.2) HU] and at lateral segment [(86.8 ± 7.9) HU vs. (95.6 ± 11.6) HU] in severe stenosis group than in normal group (all P < 0.05). Myocardial density of patients with old myocardial infarction was significantly reduced in non-infarct segment [(70.9 ± 8.3) HU vs.(98.7 ± 7.3) HU, P < 0.01] and increased in infarct segment [(42.5 ± 15.7) HU vs. (17.8 ± 4.1) HU, P < 0.01] post contrast enhancement.</p><p><b>CONCLUSION</b>CTA could be used to evaluate the severity of the left coronary artery stenosis based on myocardial density measurement. Myocardial delayed enhancement derived from CTA could be used to identify infarct segments.</p>
