Objective To assess the predictive value of coronary angiography TIMI myocardial perfusion grade (TMPG), electrocardiogram (ECG) single-lend ST segment resolution (STR), ECG Max-ST-segment deviation (MaxSTE) on judging myocardial reperfusion after primary angioplasty in the patients with acute myocardial infarction (AMI). Methods Primary percutaneous coronary intervention(PCI) was performed in 42 patients within 12 hours after AMI onset. Coronary angiography and ECG was done before and after angioplasty. TMPG, ECG single-leed STR and MaxSTE were used to assess myocardial reperfusion immediately after PCI. Myocardial perfusion scan was examined in all the patients using99mTc-MIBI SPECT on day 7±2. Results Compared with the level of myocardial perfusion demonstrated in myocardial scan of 99mTc-MIBI SPECT, the sensitivity, specificity and accuracy of TMPG, single-lead STR and MaxSTE was calculated. The sensitivity of TMPG, single-lead STR and MaxSTE was 93.75%, 87.50% and 81.25%, respectively, the specificity of them was 20.00%, 80.00% and 80.00%, respectively, and the accuracy was 76.19%, 85.71% and 80.95%, respectively. The findings in single-lead STR and MaxSTE matched well with the results of myocardial scan of 99mTc-MIBI SPECT. Conclusion In the patients suffering from AMI treated with PCI, ECG is an effective method to assess myocardial tissue reperfusion.

Objective:To analyse the clinical application value of Lone-Star perineal exposure technique in performing abdominal perineal resection (APR).Methods:Conducted a retrospective review of 17 rectal cancer patients, including 13 males, 4 females, aged from 44 to 82 years old, with the average age of (67.6±9.7) years who underwent APR at Anqing Municipal Hospital from January 2020 to July 2024. The Lone-Star retractor-assisted (LSR) exposure method was employed for the perineal operation. After incising the skin and subcutaneous tissue, a Lone-Star retractor was utilized, with eight small hooks used to extend the incision in multiple directions, facilitating the release of deep tissues. The hooks were dynamically adjusted to optimize surgical field exposure.Results:All 17 patients were successfully underwent laparoscopic-assisted APR. Fifteen operations were independently performed by a single surgeon, while 2 required assistance for intraoperative arterial hemostasis. No perforations occurred, and all specimens had a negative circumferential resection margin (CRM). Postoperative complications were observed in 4 patients, including urinary retention in one, pulmonary infection in one, wound seroma in one, and stoma mucosal detachment in one, all of which were classified as Clavien-Dindo grade 3 or lower and cured.Conclusions:The LSR exposure technique may significantly improve perineal exposure during APR for rectal cancer. It could potentially enhance intraoperative safety and efficiency, and facilitate single-operator surgery.
