Background Transanal total mesorectal excision(taTME)or intersphincteric resection(ISR)has recently proven to be a valid and safe surgical procedure for low rectal ***,studies focusing on the combination of these two technologies are *** study aimed to evaluate perioperative results,long-termoncologic outcomes,and anorectal functions of patients with low rectal cancer undergoing taTME combined with ISR,by comparing with those of patients undergoing laparoscopic abdominoperineal resection(laAPR).Methods After 1:1 propensity score matching,200 patients with low rectal cancer who underwent laAPR(n=100)or taTME combined with ISR(n=100)between September 2013 and November 2019 were *** demographics,clinicopathological characteristics,oncological outcomes,and anal functional results were *** Patients in the taTME-combined-with-ISR group had less intraoperative blood loss(79.6672.6 vs 107.3665.1 mL,P=0.005)and a lower rate of post-operative complications(22.0%vs 44.0%,P<0.001)than those in the laAPR *** overall local recurrence rates were 7.0%in both groups within 3 years after *** 3-year disease-free survival rates were 86.3%in the taTME-combined-with-ISR group and 75.1%in the laAPR group(P=0.056),while the 3-year overall survival rates were 96.7%and 94.2%,respectively(P=0.319).There were 39 patients(45.3%)in the taTME-combined-with-ISR group who developed major low anterior resection syndrome,whereas 61 patients(70.9%)had good post-operative anal function(Wexner incontinence score≤10).Conclusion We found similar long-term oncological outcomes for patients with low rectal cancer undergoing laAPR and those undergoing taTME combined with *** receiving taTME combined with ISR had acceptable post-operative anorectal function.

Photoactive complexes of nonprecious transition metals, mainly including those in the first-row and partially the second-row of the Periodic table of elements, have received increasing attention in view of their low cost and long-term sustainability. They are recognized as promising alternatives to noble transition metal complex congeners that have been extensively studied in optoelectronic devices, artificial photosynthesis, photocatalysis, biodiagnostics, and therapeutics, etc. This review is devoted to a comprehensive summary on the classical and recent advances on photoactive nonprecious transition metal complexes, including photoactive Zr, V, Cr, Mo, and W complexes, Mn complexes and hybrids, Fe, Co, Ni, and Cu complexes, and Zn and Cd complexes and hybrids. A particular focus is given on the molecular design, modulation of photophysical and photochemical properties, and applications of the representative and lately-developed nonprecious metal complexes. In addition, a perspective on the future development in this field is provided at the end of this review.
