Aim To investigate the mechanism by which sufentanil(Suf)improved hypoxia-reoxygen-ation(H/R)-induced myocardial cell injury by regula-ting hypoxia inducible factor-1α(HIF-1α)and KC-NQ1 opposite strand/antisense transcript 1(Kcnq1ot1).Methods Bioinformatics analysis was conducted to predict the interaction between HIF-1αand Kcnq1ot1.Subsequently,H9c2 cells were divided into multiple treatment groups:Ctrl group,H/R group,and Suf group.Further grouping was based on different transfection conditions,including oe-HIF-1α group,oe-HIF-1α+Suf group,sh-HIF-1α group,and sh-HIF-1α+Kcnq1ot1 group.Cell viability was detected u-sing the MTT assay,cell apoptosis was detected using the TUNEL assay,and the concentrations of CK-MB and HBDH in cell supernatants were measured using ELISA.HIF-1α protein expression in cellswas deter-mined by Western blot,and the mRNA expression level of Kcnq1ot1 was measured by reverse transcription quantitative PCR(RT-qPCR).Additionally,a rat model of myocardial is chemia reperfusion was con-structed to evaluate the therapeutic potential of Suf for myocardial ischemia reperfusion injury in vivo.Results The results of bioinformatics analysis showed a direct interaction between HIF-1α and Kcnq1ot1.Compared with the Ctrl group,the H/R group showed significantly reduced H9c2 cell viability,increased cell apoptosis,and significantly upregulated concentrations of CK-MB and HBDH,along with significantly enhanced expres-sion of HIF-1α and Kcnq1ot1(all P＜0.05).When H9c2 cells were transfected with oe-HIF-1 α,cell via-bility further decreased,apoptosis was worsened,and CK-MB and HBDH concentrations further increased(all P＜0.05);however,these adverse effects were significantly inhibited when combined with Suf inter-vention(all P＜0.05).Additionally,compared with the H/R group,the sh-HIF-1α group showed signifi-cantly improved cell viability,reduced apoptosis and decreased CK-MB and HBDH concentrations(all P＜0.05);however,these improvements were partially re-versed upon transfection with Kcnq1ot1(all P＜0.05).Animal experiments confirmed that Suf could improve myocardial ischemia-reperfusion injury in myo-cardial ischemia-reperfusion injury rats.Conclusions Suf improves myocardial H/R injury by inhibiting the HIF-1α-Kcnq1ot1.

Objective To explore the relevant factors of new-onset conduction disturbance(NOCD)after transcatheter aortic valve replacement(TAVR),such as anatomical structure,device type,surgical strategies,etc.,discover relevant predictive factors,and establish a predictive model to assess the risk of conduction blockages.Methods From January 2016 to March 2022,clinical data of symptomatic patients with severe aortic valve stenosis or severe regurgitation who underwent TAVR at Xiangya Second Hospital of Central South University were collected through the hospital information system and imaging database.ECG,echocardiography,CTA,surgical materials,etc.,were extracted and analyzed by specialists.SPSS software was used for statistical analysis,and a multi-factor regression prediction model for NOCDwas built.Results A total of 184 patients were included,the occurrence rate of NOCD after TAVR was 31.0%,pure regurgitation patients'NOCD occurrence rate was 63.6%(7/11).The NOCD group had a larger aortic angles[(57.7±10.3)°vs.(52.0±9.0)°,P＜0.001],larger Oversizing[(129±28)%vs.(120±21)%,P=0.018],deeper implantation depth[(7.2±5.1)mm vs.(4.8±4.2)mm,P=0.001],and higher pure regurgitation patients'proportion[12.3%vs.3.1%,P=0.037]than the non-NOCD group.Multifactorial Logistic regression analysis indicated that an aorta angle＞54.5°(OR 3.78,95%CI 1.86-7.63,P＜0.001)or implantation depth＞5.7 mm(OR 3.39,95%CI 1.68-6.85,P＜0.001)are independent risk factors for new onset conduction disturbances after TAVR,and a predictive model was established with aortic angle,implantation depth,and Oversizing ratio as variables.The receiver operating characteristics curve showed area under ROC curve 0.709,95%CI 0.623-0.795,predicting NOCD after TAVR.Conclusions A retrospective analysis carried out at a single center discovered that the aortic angle in the NOCD group was larger than that in the non-NOCD group,the Oversizing ratio was higher,the implantation location was deeper,and there was a higher proportion of patients with pure regurgitation lesions.An aortic angle greater than 54.5°or an implantation depth more than 5.7 mm were identified as independent risk factors for NOCD after TAVR.

Objective: To investigate the causes and management of long-term persistent pelvic presacral space infection. Methods: Clinical data of 10 patients with persistent presacral infection admitted to the Cancer Hospital of Zhengzhou University from October 2015 to October 2020 were collected. Different surgical approaches were used to treat the presacral infection according to the patients' initial surgical procedures. Results: Among the 10 patients, there were 2 cases of presacral recurrent infection due to rectal leak after radiotherapy for cervical cancer, 3 cases of presacral recurrent infection due to rectal leak after radiotherapy for rectal cancer Dixons, and 5 cases of presacral recurrent infection of sinus tract after adjuvant radiotherapy for rectal cancer Miles. Of the 5 patients with leaky bowel, 4 had complete resection of the ruptured nonfunctional bowel and complete debridement of the presacral infection using an anterior transverse sacral incision with a large tipped omentum filling the presacral space; 1 had continuous drainage of the anal canal and complete debridement of the presacral infection using an anterior transverse sacral incision. 5 post-Miles patients all had debridement of the presacral infection using an anterior transverse sacral incision combined with an abdominal incision. The nine patients with healed presacral infection recovered from surgery in 26 to 210 days, with a median time of 55 days. Conclusions: Anterior sacral infections in patients with leaky gut are caused by residual bowel secretion of intestinal fluid into the anterior sacral space, and in post-Miles patients by residual anterior sacral foreign bodies. An anterior sacral caudal transverse arc incision combined with an abdominal incision is an effective surgical approach for complete debridement of anterior sacral recalcitrant infections.
