Objective To assess the feasibility and curative effects of laser surgery in treatment of early-stage glottic carcinoma under self-retaining laryngoscope with nasal endoscopic assistance.Methods Thirteen cases of glottic carcinoma(TisN0M0:2 cases;T1aN0M0:7 cases;T1bN0M0:3 cases;T2N0M0:1 case) extirpated with Nd:YAG laser or Diomed laser from June 1999 to March 2003 were retrospectively analyzed.Because of the poor glottic exposure with self-retaining laryngoscope under general anesthesia,various angular nasal endoscopes were used.The tumor was distinctly displayed on monitor screen with nasal endoscopic assistance and were completely removed through vapourization or removed with Nd:YAG laser or Diomed laser.Results The follow-up period was three to five years.Two patients were found to have local recurrence.One patient received treatment with Nd:YAG laser surgery under electronic laryngoscope with local and superfacial anesthesia,and the patient was followed up for three years without showing recurrence.The other patient underwent vertical hemilaryngectomy and was followed up for three and half years without showing recurrence.All 13 cases were followed up for three years,and all of them were alive.Three-year survival rate was 100%(13/13).When they were followed up for five years,one patient lost track(counted as death),therefore the five-year survival rate was 92.3%(12/13).Conclusions With the assistance of various angular nasal endoscope,the glottic tumors can be exposed distinctly under self-retaining laryngoscope and removed completely.Nd:YAG laser or Diomed laser is an effective and safe procedure with minimal invasion for the treatment of early-stage glottic carcinoma.The advantages of this technique include lower complication rate and high rate of preservation of laryngeal functions,avoidance of tracheotomy and the sequela of laryngeal fissure.

PURPOSE: Several studies have compared the effects of coronary stenting and coronary-artery bypass grafting (CABG) on left main coronary artery (LMCA) disease. However, there are limited data on the long-term outcomes of these two interventions in diabetic patients. MATERIALS AND METHODS: We evaluated 56 patients with LMCA stenosis who underwent drug-eluting stent (DES) implantation and 116 patients who underwent CABG in a single hospital in China between January 2004 and December 2006. We compared long-term major adverse cardiac events (death; a "serious outcome" composite of death, myocardial infarction, or stroke; and target-vessel revascularization). RESULTS: In-hospital (30-day) mortality was 0% for the DES group and 3.4% for the CABG group (p=0.31). There was no difference between the two groups in terms of risk of death [hazard ratio for stenting group, 0.49; 95% confidence interval (CI), 0.13-1.63; p=0.55] or risk of serious outcome (hazard ratio for DES group, 1.11; 95% CI, 0.39-1.45; p=0.47). The target-vessel revascularization rate was higher in the DES group than in the CABG group (hazard ratio, 3.67; 95% CI, 1.24-11.06; p=0.018). CONCLUSION: In this cohort of diabetic patients with LMCA stenosis, there was no difference in composite endpoints between patients receiving DESs and those undergoing CABG. However, stenting was associated with higher rates of target-vessel revascularization than CABG. DES implantation in diabetic patients with LMCA disease was found to be at least as safe as CABG.

OBJECTIVE:Percutaneous sacroiliac screw internal fixation has become the main surgical procedure for the treatment of posterior pelvic ring fractures;however,the unassisted closure operation requires high operator experience and repeated fluoroscopy increases the radiation hazard for patients and medical personnel.This article compares the clinical efficacy of robot-assisted versus unassisted percutaneous sacroiliac screw placement for posterior pelvic ring fractures by meta-analysis. METHODS:Computer searches of CNKI,WanFang,VIP,CBM,PubMed,Embase,Cochrane Library and ClinicalTrials.gov were conducted from the time of database inception to December 2022.The literature on the clinical efficacy of robot-assisted versus freehand percutaneous sacroiliac screw placement in the treatment of posterior pelvic ring fractures was collected in and outside China.The data were independently screened and extracted by two investigators according to the inclusion and exclusion criteria,respectively.The quality of randomized controlled trials was evaluated using Cochrane risk assessment criteria.The quality of included cohort studies was assessed using the Newcastle-Ottawa Scale.Meta-analysis was performed using RevMan 5.4 software for inclusion metrics.Outcome metrics included operative time,intraoperative bleeding,fluoroscopy time,fluoroscopy frequency,number of holes drilled,Majeed postoperative function score,the excellent and good rates of Matta fracture reduction,the excellent and good rates of Gras screw position,fracture healing time and complications. RESULTS:(1)A total of 13 publications were included,2 were randomized controlled trials both referring to randomized methods,11 non-randomized controlled studies were evaluated for quality of literature according to the Newcastle-Ottawa Scale,1 scored 8,9 scored 7;and 1 scored 6;the quality of literature was good.A total of 748 patients were included,including 430 in the robot-assisted group and 318 in the freehand group.(2)The results of the meta-analysis showed that the operative time(MD=-28.30,95%CI:-40.20 to-16.40),intraoperative bleeding(MD=-6.36,95%CI:-10.06 to-2.66),intraoperative fluoroscopy time(MD=-12.13,95%CI:-19.54 to-4.72),intraoperative fluoroscopy frequency(MD=-17.39,95%CI:-29.00 to-5.78),number of intraoperative needle drillings(SMD=-9.50,95%CI:-14.27 to-4.73)and the excellent and good rates of Gras screw position(OR=8.65,95%Cl:3.26-22.92)in the robot-assisted group were significantly better than those in the freehand group(P<0.05).(3)In the robot-assisted group,the overall postoperative complication rate was significantly reduced(OR=0.10,95%Cl:0.02-0.48,P<0.05).(4)No significant difference was detected in fracture healing time(MD=-0.08,95%CI:-0.21,0.06),the excellent and good rates of Matta fracture repositioning rate(OR=2.06,95%Cl:0.97-4.39),and Majeed functional score(MD=0.91,95%CI:-0.31-2.13)between both groups(P>0.05). CONCLUSION:Compared with freehand sacroiliac joint nailing,robotic assistance shortens the operative time,reduces intraoperative bleeding,decreases radiation damage to patients and medical staff,improves the excellent and good rate of screw position,and reduces the overall incidence of postoperative complications in patients,but there was no significant improvement in fracture reduction quality,fracture healing time,and postoperative function.In the future,more large-sample,multicenter,and high-quality randomized controlled trials are still needed to verify.

Background::The goal of the assisted reproductive treatment is to transfer one euploid blastocyst and to help infertile women giving birth one healthy neonate. Some algorithms have been used to assess the ploidy status of embryos derived from couples with normal chromosome, who subjected to preimplantation genetic testing for aneuploidy (PGT-A) treatment. However, it is currently unknown whether artificial intelligence model can be used to assess the euploidy status of blastocyst derived from populations with chromosomal rearrangement.Methods::From February 2020 to May 2021, we collected the whole raw time-lapse videos at multiple focal planes from in vitro cultured embryos, the clinical information of couples, and the comprehensive chromosome screening results of those blastocysts that had received PGT treatment. Initially, we developed a novel deep learning model called the Attentive Multi-Focus Selection Network (AMSNet) to analyze time-lapse videos in real time and predict blastocyst formation. Building upon AMSNet, we integrated additional clinically predictive variables and created a second deep learning model, the Attentive Multi-Focus Video and Clinical Information Fusion Network (AMCFNet), to assess the euploidy status of embryos. The efficacy of the AMCFNet was further tested in embryos with parental chromosomal rearrangements. The receiver operating characteristic curve (ROC) was used to evaluate the superiority of the model. Results::A total of 4112 embryos with complete time-lapse videos were enrolled for the blastocyst formation prediction task, and 1422 qualified blastocysts received PGT-A ( n = 589) or PGT for chromosomal structural rearrangement (PGT-SR, n = 833) were enrolled for the euploidy assessment task in this study. The AMSNet model using seven focal raw time-lapse videos has the best real-time accuracy. The real-time accuracy for AMSNet to predict blastocyst formation reached above 70% on the day 2 of embryo culture, and then increased to 80% on the day 4 of embryo culture. Combing with 4 clinical features of couples, the AUC of AMCFNet with 7 focal points increased to 0.729 in blastocysts derived from couples with chromosomal rearrangement. Conclusion::Integrating seven focal raw time-lapse images of embryos and parental clinical information, AMCFNet model have the capability of assessing euploidy status in blastocysts derived from couples with chromosomal rearrangement.
