@#AIM:To evaluate the safety and efficacy of Ex-press implantation combined with phacoemulsification in primary angle-closure glaucoma(PACG)patients with cataract. <p>METHODS:Sixty-two cases(70 eyes)of primary angle-closure glaucoma with cataract were randomly divided into clinical trail group(34 eyes)and control group(36 eyes). The clinical trail group was treated with Ex-press miniature drainage device implantation combined with phacoemulsification and intraocular lens implantation. The control group was treated with trabeculectomy combined with phacoemulsification and intraocular lens implantation. The best corrected visual acuity(BCVA), intraocular pressure(IOP), corneal endothelium and central anterior chamber depth(ACD), complications were recorded preoperatively as well as postoperatively on day 1, 7 and at 1, 3, 6, and 12mo. <p>RESULTS: At the last review of trail group after operation, the best visual acuity(Log MAR)was 0.53± 0.19, which was better than the preoperative visual acuity 0.83± 0.41(<i>P</i>=0.001). The postoperative IOP in the clinical trail group decreased, which was 7.37±2.94, 9.88±3.18, 10.84±2.68, 12.28±2.81, 12.82±2.84 and 14.14±3.41mmHg at 1d, 1wk, 1, 3, 6, 12mo compared with the preoperative one(31.3±6.85mmHg)(<i>P</i><0.05). There were no differences on postoperative IOP between the two groups(<i>P</i>>0.05). The ACD, corneal endothelial cell density of the clinical trail group and the control group obviously increased after operation, and the difference in ACD between the two groups after operation was not statistically significant(<i>P</i>>0.05). The relative success rates of the clinical trail group and the control group were 97.1% and 94.4% respectively at 12mo after surgery, and the difference was not statistically significant(<i>P</i>>0.05). <p>CONCLUSION: The operation of Ex-press miniature glaucoma drainage device implantation combined with phacoemulsification and intraocular lens implantation, which can reduce IOP and improve visual acuity evidently with less complications, is a safe and effective combined operation for primary angle-closure glaucoma with cataract.

<p><b>OBJECTIVE</b>To evaluate the clinical value of retrospective electrocardiogram (ECG) -editing technique in dual-source computed tomography (CT) coronary angiography in patients with arrhythmia.</p><p><b>METHODS</b>Totally 73 patients with arrhythmia during dual-source CT coronary angiography were included into this study. A retrospective gating technique and ECG-editing technique (Insert Sync; Disable Sync; Delete Sync; Shift R-peak) were used in patients who needed ECG-editing. Two experienced radiologists evaluated in consensus all pre-editing and post-editing reconstructed images and recorded scores according to the American Heart Association guidelines on coronary segmentation on a per segment basis. Image quality of all coronary segments was assessed using a four-point grading scale from excellent (4 scores) to non-assessable (1 score) .</p><p><b>RESULTS</b>The overall mean image quality of 34 patients who did not need ECG-editing was 3.42 ± 0.20. In 39 patients who needed ECG-editing, the overall mean image quality before and after ECG-editing was 2.39?0.37 and 3.22?0.24. The mean image quality in every segment between pre-editing and post-editing was also significantly different (P<0.01) .</p><p><b>CONCLUSION</b>ECG-editing technique can remarkably improve image quality of coronary artery segments by reducing or even eliminating the artifact produced by arrhythmia during dual-source CT coronary angiography.</p>
