BACKGROUND: The available evidence regarding the benefits of percutaneous coronary intervention (PCI) on patients receiving dialysis with coronary artery disease (CAD) is limited and inconsistent. This study aimed to evaluate the association between PCI and clinical outcomes as compared with medical therapy alone in patients undergoing dialysis with CAD in China. METHODS: This multicenter, retrospective study was conducted in 30 tertiary medical centers across 12 provinces in China from January 2015 to June 2021 to include patients on dialysis with CAD. The primary outcome was major adverse cardiovascular events (MACE), defined as a composite of cardiovascular death, non-fatal myocardial infarction, and non-fatal stroke. Secondary outcomes included all-cause death, the individual components of MACE, and Bleeding Academic Research Consortium criteria types 2, 3, or 5 bleeding. Multivariable Cox proportional hazard models were used to assess the association between PCI and outcomes. Inverse probability of treatment weighting (IPTW) and propensity score matching (PSM) were performed to account for potential between-group differences. RESULTS: Of the 1146 patients on dialysis with significant CAD, 821 (71.6%) underwent PCI. After a median follow-up of 23.0 months, PCI was associated with a 43.0% significantly lower risk for MACE (33.9% [ n  = 278] vs . 43.7% [ n  = 142]; adjusted hazards ratio 0.57, 95% confidence interval 0.45-0.71), along with a slightly increased risk for bleeding outcomes that did not reach statistical significance (11.1% vs . 8.3%; adjusted hazards ratio 1.31, 95% confidence interval, 0.82-2.11). Furthermore, PCI was associated with a significant reduction in all-cause and cardiovascular mortalities. Subgroup analysis did not modify the association of PCI with patient outcomes. These primary findings were consistent across IPTW, PSM, and competing risk analyses. CONCLUSION This study indicated that PCI in patients on dialysis with CAD was significantly associated with lower MACE and mortality when comparing with those with medical therapy alone, albeit with a slightly increased risk for bleeding events that did not reach statistical significance.

Objective:To evaluate the clinical efficacy of transoral robotic surgery (TORS) in the treatment of malignant tongue base tumors.Methods:A multicenter study was conducted to collect and analyze the clinical data of patients with malignant tongue base tumors who underwent TORS at five otolaryngology-head and neck surgery centers in China, including Eye Ear Nose and Throat Hospital of Fudan University, Sun Yat-sen University Cancer Center, Tongji Hospital of Huazhong University of Science and Technology, Sun Yat-sen Memorial Hospital of Sun Yat-sen University, and the First Affiliated Hospital of China Medical University between January 2017 and January 2023. Among the patients, 38 were males and 11 were females, with a mean age of 59.0±8.8 years. Baseline characteristics, complications, and follow-up data were compared between groups. Independent sample t-tests or Mann-Whitney U tests was used for comparisons of continuous variables; chi-square tests or Fisher′s exact tests was applied for categorical variables. Survival analysis was performed using the Kaplan-Meier method to calculate overall survival and disease-free survival, and differences between groups were compared using the log-rank test. Results:Among the 49 patients, 41 (83.7%) were diagnosed with squamous cell carcinoma (SCC), with a p16 positive rate of 51.2% (21/41). There were no statistically significant differences between the p16-positive group ( n=21) and the p16-negative group ( n=20) in age, sex, or postoperative bleeding (all P>0.05). However, there was a significant difference in TNM stage between the two groups ( χ2=14.556, P=0.020), with the p16-positive group predominantly in stage I (66.7%) and the p16-negative group primarily in stages Ⅲ and Ⅳ (40.0% and 30.0%, respectively). The postoperative tracheotomy rate was 30.6% (15/49), and the incidence of postoperative bleeding was 6.1% (3/49). The 1-year and 3-year overall survival rates were 98.0% and 92.5%, respectively, while, the 1-year and 3-year disease-free survival rates were 89.2% and 84.9%, respectively. No significant differences were observed between the p16-positive and p16-negative groups in 3-year overall survival (100% vs. 83.8%, χ2=1.093, P=0.518) or 3-year disease-free survival (68.2% vs. 88.9%, χ2=2.161, P=0.382). Conclusion:TORS for malignant tongue base tumors demonstrates high clinical safety and favorable oncological outcomes.

The OS and PFS of the 3-year group were 85.9% and 82.8%, respectively. The prognosis of patients with locally early-stage was better than that of locally advanced patients, with the OS of 94.4% for T1-2 vs. 78.0% for T3 ( P=0.005) and the PFS of 91.2% for T1-2 vs. 75.0% for T3 ( P=0.011) in the 2-year group; the OS of 91.1% for T1-2 vs. 65.0% for T3 ( P=0.004) and the PFS of 88.6% for T1-2 vs. 60.0% for T3 ( P=0.002) in the 3-year group; and also, the OS of 90.0% for stage Ⅰ-Ⅱ vs. 79.5% for stage Ⅲ-Ⅳ ( P=0.204) and the PFS of 86.7% for stage Ⅰ-Ⅱ vs. 76.9% for stage Ⅲ-Ⅳ ( P=0.188) in the 3-year group. The prognosis of HPV-positive TSCC patients was better than that of HPV-negative patients in the 3-year group, with the OS of 90.9% for HPV-positive vs. 80.5% for HPV-negative ( P=0.045) and the PFS of 90.9% for HPV-positive vs. 75.6% for HPV-negative ( P=0.047). The average time of postoperative tracheal cannula indwelling was 25.1 days. The indwelling rate and average indwelling time of the postoperative nasogastric tube were 94.3% (148/157) and 8.5 days, respectively. Conclusion:TORS has outstanding survival benefits for TSCC patients. HPV-positive TSCC patients have a better prognosis than HPV-negative patients. TORS treatment of TSCC patients has advantages in postoperative recovery and quality of life.

Objective:To summarize preliminary experience and outcomes of transoral robotic surgery (TORS) in hypopharyngeal cancer.Methods:Clinical data of 28 patients with hypopharyngeal cancer underwent TORS with Da Vinci Si or Xi surgical system in three medical centers(Tongji Hospital, Tongji Medical College, Huazhong University of Science and Technology, Sun Yat-sen Memorial Hospital, Sun Yat-sen University and Eye & ENT Hospital of Fudan University) in China from Sep 2017 to Mar 2024 were respectively analyzed. All patients were males, aged from 47 to 82(62.5±7.1) years old. According to TNM staging of AJCC, the stages included T1 in 6 cases, T2 in 17 cases, T3 in 3 cases and T4 in 2 cases; N0 in 18 cases, N1 in 3 cases, N2 in 6 cases, N3 in 1 case. SPSS version 26 was applied, and with Kaplan-Meier surviving curves, overall survival, local control rate and disease-free survival for those patients were calculated.Results:All 28 patients underwent successfully their TORS, no any case with transfer opening or positive surgical margin. Two patients died within one month after surgery. Two patients experienced minor oral bleeding, and subsenquently was cured. The follow-up period ranged from 1 to 81 months, with an average of 24.8 months, in which, five patients(17.9%) died, five patients(17.9%) experienced local recurrence and four patients(14.3%) had distant metastases. The three year overall survival, local control rate and disease-free survival were 77.1%, 74.6% and 57.1%, respectively.Conclusion:In properly selected cases of hypopharyngeal cancer, TORS can offer acceptable survival and local control rates, which can be considered as a new useful option for the surgery of hypopharyngeal cancer.

Objective:To investigate the efficacy and feasibility of transoral robotic surgery (TORS) for resection of tumors in the parapharyngeal spaces.Methods:The clinical data of 57 patients who underwent TORS for parapharyngeal space tumors from September 2018 to February 2024 were retrospectively analyzed. These patients were treated at five medical institutions: The First Affiliated Hospital of China Medical University, Eye & ENT Hospital of Fudan University, Sun Yat-sen Memorial Hospital, Sun Yat-sen University, Tongji Hospital, Tongji Medical College, Huazhong University of Science and Technology, and Sun Yat-sen University Cancer Center. The patients were 28 males and 29 females, aged 17-77 years (median age, 47 years). The pathological types, locations, and sizes of the tumors, operation time, intraoperative bleeding volumes, postoperative hospital stays, and postoperative complications were evaluated. The data were analyzed using SPSS 27.0 software.Results:Postoperative pathological examination revealed 11 types of benign tumors. Among 57 cases, 27 cases had their tumors in the prestyloid spaces, predominantly with pleomorphic adenoma ( n=17), and 30 cases in the retrostyloid spaces, predominantly with schwannoma ( n=22). The tumor volumes ranged from 0.6 to 130.1 cm3, the intraoperative bleeding volumes ranged from 5 to 1 000 ml, the operation time ranged from 20 to 390 min, and the postoperative hospital stays ranged from 2 to 25 days. The total costs for individual cases were 36 000-100 000 yuan, with the highest cost in the case suffering from cerebrovascular accident. Four patients(7.0%) had tracheotomy and 36(63.2%) had nasogastric tube placement. Among the 57 patients, 5 had postoperative cavity effusion, 2 had wound dehiscence, 2 had cerebrovascular accidents, 1 had Horner syndrome, and 2 had other complications. The patients were followed up for 1-67 months, with only 1 patient with intracranial and extracranial communication relapsed. Conclusion:TORS is a safe and feasible approach for treating parapharyngeal space tumors, offering advantages such as minimal invasiveness, reduced blood loss, and faster recovery. It is suitable for parapharyngeal space tumors of various pathological types and locations. The postoperative complications are manageable, with favorable long-term follow-up results and low recurrence rates.

Objective:To investigate the ultra-long-term antihypertensive efficacy, safety, major adverse events, and survival benefits of renal denervation (RDN) in patients with resistant hypertension (rHTN) and mild chronic kidney disease (CKD).Methods:This real-world, single-center retrospective study enrolled patients with rHTN and mild CKD who underwent RDN at Tianjin First Central Hospital between October 2011 and June 2016. Office blood pressure, home self-measured blood pressure, 24-hour ambulatory blood pressure, serum creatinine, estimated glomerular filtration rate, and urine albumin-to-creatinine ratio were collected at baseline and at 1, 5, and 13 years post-RDN. The total daily defined dose of antihypertensive medications at 13 years post-RDN was recorded, along with endpoint events during follow-up, including cardiovascular death, all-cause death, hospitalization for heart failure, myocardial infarction, and stroke. Patients were stratified according to CKD stage (G1-G2 vs. G3a) and baseline systolic blood pressure (mild-to-moderate vs. severe hypertension), and follow-up data were compared across subgroups.Results:A total of 40 patients were included, aged (51±15) years, including 26 (65%) males. At the 13-year follow-up, office systolic blood pressure (SBP) and diastolic blood pressure (DBP) decreased by (-32±20) mmHg and (-15±14) mmHg (1 mmHg=0.133 kPa), respectively; reductions in home self-measured blood pressure (SBP: (-25±14) mmHg, DBP: (-10±11) mmHg) and 24-hour ambulatory blood pressure (SBP: (-16±9 mmHg, DBP: (-10±6) mmHg) were also observed, alongside a reduction in the total daily defined dose of antihypertensive medications by (1.1±0.9) compared to baseline. Renal function assessments showed no significant differences at 13 years versus baseline in serum creatinine ((105±51) μmol/L vs. (96±22) μmol/L), estimated glomerular filtration rate ((72±22) ml·min -1·1.73 m -2 vs. (78±17) ml·min -1·1.73 m -2), or urine albumin-to-creatinine ratio ((101±86) mg/g vs. (127±82) mg/g) (all P>0.05). All-cause and cardiovascular mortality rates during follow-up were 13% (5/40) and 8% (3/40), respectively. Subgroup analysis results showed that, although CKD G1-G2 patients had smaller reductions in office SBP ((-31±20) mmHg vs. (-34±19) mmHg) and DBP ((-13±10) mmHg vs. (-25±18) mmHg) compared to G3a patients at 13 years, intergroup differences were not significant (all P>0.05). In contrast, severe hypertension subgroup exhibited greater reductions in office SBP ((-55±13) mmHg vs. (-20±10) mmHg) and DBP ((-24±17) mmHg vs. (-13±10) mmHg) versus mild-to-moderate hypertension subgroup (all P<0.05). Conclusion:RDN demonstrates sustained antihypertensive efficacy with favorable renal safety in rHTN patients with mild CKD. Patients with higher baseline systolic blood pressure may exhibit better responsiveness to RDN.

Renal denervation (RDN) as an interventional approach for treating refractory hypertension has developed a variety of ablation strategies and different energy ablation techniques. This article reviews the principles, characteristics, clinical advantages, and the latest research progress of mapping/selective RDN system. Selective RDN identifies “hot spots” (sympathetic nerve-rich points) through renal nerve stimulation (RNS) for targeted ablation, while avoiding “cold spots” (parasympathetic nerve-rich points) and “neutral points”, achieving more precise sympathetic nerve regulation. Animal experiments and clinical studies have shown that mapping/selective RDN can more effectively lower blood pressure, achieve blood pressure targets, and reduce the burden of antihypertensive drugs (reducing the drug index by 3.25). Mapping/selective RDN system provides a personalized solution for hypertension treatment, improving treatment efficiency and reducing complications.
