The 2024 World Conference on Lung Cancer (WCLC) and the European Society for Medical Oncology (ESMO) Annual Meeting, two of the most prestigious events in oncology, have concluded sequentially. As the most authoritative annual gatherings in lung cancer and the entire oncology field, the WCLC and ESMO conferences brought together top oncology experts and scientists from around the world to share, discuss, and publish the latest cutting-edge advancements in oncology. In both conferences, lung cancer immunotherapy remained a hot topic of considerable interest. This article aims to summarize and discuss the important research progress on perioperative immunotherapy for non-small cell lung cancer reported at the two conferences.

Objective:To investigate the effect of basket assisted retrograde ureteral soft lithotripsis retrograde intrarenal surgery (RIRS) in the treatment of subcalyceal calculi and its effect on stone clearance.Methods:A retrospective cohort study method was conducted on 120 patients with lower calyx stones treated at Jiaozhou Central Hospital of Qingdao City, from October 2021 to January 2024. There were 66 males and 54 females, aged (48.10±10.11) years old. The patients were divided into two groups based on their surgical methods: 60 patients who received only RIRS treatment were in the control group, while 60 patients who underwent RIRS with the assistance of a stone retrieval basket were in the observation group. The study compared various perioperative indicators (such as intraoperative blood loss, surgical duration, and hospital stay), as well as the stone clearance rates, inflammation levels, and postoperative complications at 3 days (short-term) and 30 days (long-term) after surgery. Measurement data with normal distribution were expressed as mean±standard deviation ( ± s), and t-test was employed for inter-group comparisons. Chi-square test was used for inter-group comparisons of count data. Results:The operation time of the observation group was (78.26±10.54) min, and that of the control group was (70.65±8.67) min. The difference between the two groups was statistically significant ( P<0.05). There was no difference between the two groups in intraoperative bleeding, the first time to get out of bed after surgery and the postoperative hospital stay ( P>0.05). The stone expulsion time in the observation group was (16.38±4.22) d, while that in the control group was (18.96±5.10) d, the stone removal rates of the observation group at 3 days and 30 days after surgery were 88.33% and 95.00% respectively, while those of the control group were 73.33% and 83.33% respectively. There was a statistically significant difference between the two groups ( P<0.05). The stone expulsion time was shorter in the observation group compared to the control group, with a statistically significant difference ( P<0.05). There were no significant differences in postoperative inflammatory factors between the two groups( P>0.05). The incidence of postoperative complications in the observation group was 6.67%, and that in the control group was 20.00%. The difference between the two groups was statistically significant ( P<0.05). Conclusions:Stone basket removal combined with RIRS is safe and feasible, which can not only improve the stone clearance rate, but also reduce the incidence of postoperative complications without increasing the inflammatory reaction, and has a significant effect. However, the clinical application needs to strictly grasp the indications and avoid overtreatment in combination with the individual situation of the patients.

【Objective】 To investigate the efficacy and surgical technique of total laparoscopic radical cystectomy with intracorporeal ileal conduit urinary diversion, so as to provide reference for the selection of surgery for patients with bladder cancer. 【Methods】 Clinical data of 48 patients with bladder cancer who underwent laparoscopic radical cystectomy during Mar.2017 and Aug.2022 in our hospital were retrospectively analyzed, including 23 cases who received traditional laparoscopic radical cystectomy combined with extracorporeal ileal conduit, and 25 who received total laparoscopic radical cystectomy with intracorporeal ileal conduit.The operation time, blood loss, postoperative intestinal function recovery time, drainage tube removal time and hospital stay were compared between the two groups. 【Results】 All procedures were successfully performed, and no Clavien-Dindo>grade 3 complications were observed.The operation time, and amount of estimated blood loss of the traditional group and total laparoscopic radical group were (227.0±46.4) min vs. (253.6±58.9) min, and (131.7±79.8) mL vs. (154.0±93.0) mL, respectively.There were no differences in postoperative intestinal function recovery time and drainage tube removal time (P>0.05).The hospital stay was shorter in the total laparoscopic radical group than in the traditional group (P=0.035). 【Conclusion】 Total laparoscopic radical cystectomy with intracorporeal ileal conduit urinary diversion is safe and feasible.which is comparable to the traditional laparoscopic surgery, while the hospital stay in the total laparoscopic group is shorter, which is conducive to rapid postoperative recovery.

Objective:In this study, we aimed to compare the short-term safety of two digestive tract reconstruction techniques, laparoscopic total abdominal overlap anastomosis and laparoscopic-assisted end-to-side anastomosis, following radical resection of Siewert Type II adenocarcinoma of the esophagogastric junction.Methods:In this retrospective cohort study, we analyzed relevant clinical data of 139 patients who had undergone radical surgery for Siewert Type II esophagogastric junction adenocarcinoma. These included 89 patients treated at the First Affiliated Hospital of Air Force Medical University from November 2021 to July 2023, 36 patients treated at the First Affiliated Hospital of Xi'an Jiaotong University from December 2020 to June 2021, and 14 patients treated at the Yuncheng Central Hospital in Shanxi Province from September 2021 to November 2022. The group consisted of 107 men (77.0%) and 32 women (23.0%) of mean age 62.5±9.3 years. Forty-eight patients underwent laparoscopic total abdominal overlap anastomosis (overlap group), and 91 laparoscopic-assisted end-to-side anastomosis (end-to-side group). Clinical data, surgical information, pathological findings, postoperative recovery, and related complications were compared between the two groups.Results:There were no significant differences in general clinical data between the overlap and end-to-side anastomosis groups (all P>0.05), indicating comparability. There was no significant difference in operation time (267.2±60.1 minutes vs. 262.8±70.6 minutes, t=0.370, P=0.712). However, the intraoperative blood loss in the overlap group (100 [50, 100] mL) was significantly lower compared to the end-to-side group (100[50, 175] mL, Z=2.776, P=0.005). Compared to the end-to-side group, longer distances between the tumor and distal resection margin proximal(1.7±1.0 cm vs. 1.3±0.9 cm, t=2.487, P=0.014) and the tumor and distal resection margin (9.5±2.9 cm vs. 7.9±3.5 cm, t=2.667, P=0.009) were achieved in the overlap group. Compared with the end-to-side group, the overlap group achieved significantly earlier postoperative ambulation (1.0 [1.0, 2.0] days vs. 2.0 [1.0, 3.0] days, Z=3.117, P=0.002), earlier time to first drink (4.7±2.6 days vs. 6.2±3.0 days, t=2.851, P=0.005), and earlier time to first meal (6.0±2.7 days vs. 7.1±3.0 days, t=2.170, P=0.032). However, the hospitalization costs were higher in the overlap group (113, 105.5±37, 766.3) yuan vs. (97, 250.2±27, 746.9) yuan; this difference is significant ( t=2.818, P=0.006). There were no significant differences between the two groups in postoperative hospital stay, total number of lymph nodes cleared, or time to first postoperative flatus (all P>0.05). The incidence of surgery-related complications was 22.9%(11/48) in the overlap group and 19.8% (18/91) in the end-to-side group; this difference is not significant (χ2=0.187, P=0.831). Further comparison of complications using the Clavien-Dindo classification also showed no significant differences ( Z=0.406, P=0.685). Conclusions:Both laparoscopic total abdominal overlap anastomosis and laparoscopic-assisted end-to-side anastomosis are feasible for radical surgery for Siewert Type II esophagogastric junction adenocarcinoma. Laparoscopic total abdominal overlap anastomosis achieves longer proximal and distal resection margins and better postoperative recovery; however, end-to-side anastomosis is more cost-effective.

Objective:To explore the effectiveness of applying the ADDIE (analysis, design, develop, implement, evaluate) Model in clinical teaching for nursing interns in spine surgery department.Methods:Using a convenience sampling method, 44 nursing interns in the Department of Orthopedics at Peking Union Medical College Hospital were selected as the control group from July 2021 to May 2022, and were taught using traditional methods. From July 2022 to May 2023, 45 nursing interns were selected as the observation group, and a teaching team was formed to design a training program based on the five stages of the ADDIE instructional design model. This program was tailored to improve the overall clinical competence of the spinal surgery nursing interns. After training, the teaching effects were evaluated based on knowledge test scores, skills test scores, overall clinical competence, and teaching satisfaction.Results:After the training, the skills test scores in specialized nursing for the observation group were (94.87±1.10) points, higher than the control group's (93.98±1.41) points, with a statistically significant difference ( P<0.01). The observation group also scored higher than the control group in clinical judgment, organizational effectiveness, overall performance, and total score in the Mini-Clinical Evaluation Exercise, with statistically significant differences ( P<0.01). Additionally, the observation group reported higher satisfaction with the teaching plan and methods compared to the control group ( P<0.05) . Conclusions:Clinical teaching for spinal surgery nursing interns based on the ADDIE instructional design model can improve their specialized practical skills and overall clinical competence. The interns also expressed a high level of acceptance for this teaching design model.

Background Suicidal ideation serves as a sensitive predictive indicator for non-suicidal self-injury(NSSI)behavior,and NSSI behavior brings profound effects to both mental and physical health of senior high school students.Existing studies have made exploration on the relationship among insomnia,anxiety and NSSI behavior in the general population,but the internal mechanism of NSSI behavior in senior high school students with suicidal ideation requires further study.Objective To explore the pathway of anxiety between insomnia and NSSI behavior in senior high school students,so as to provide references for the intervention on NSSI behavior in such demographic.Methods From December 10 to 15,2021,cluster sampling was adopted to select 2 572 senior high school students across three senior high schools in Hubei Province as the research objects.Assessment was conducted by using Insomnia Severity Index(ISI),Generalized Anxiety Disorder Scale-7 item(GAD-7)and Adolescents Self-Harm Scale.Spearman correlation analysis was conducted to examine the correlation among scores of scales finished by senior high school students with suicidal ideation.Model 4 from the SPSS 20.0 Process 4.2 was employed to test the mediating path of anxiety between insomnia and NSSI behavior.Results A total of 2 421 valid questionnaires(94.13%)were recovered,which revealed 554 cases(22.88%)with suicidal ideation and 408 cases(16.85%)with NSSI behavior.The scores of ISI,GAD-7 and Adolescents Self-Harm Scale of senior high school students with suicidal ideation were higher than those of students without suicidal ideation(Z=17.124,20.611,21.314,P<0.01).As correlation analysis showed,the ISI score of senior high school students with suicidal ideation was positively correlated with scores of GAD-7 and Adolescents Self-Harm Scale(r=0.646,0.354,P<0.01),and GAD-7 score was positively correlated with the score of Adolescents Self-Harm Scale(r=0.375,P<0.01).Among senior high school students with suicide ideation,anxiety acted in a mediating role between insomnia and NSSI behavior,with effect value of 0.111(95%CI:0.053～0.185),accounting for 53.88%of the total effect.Conclusion Insomnia of senior high school students with suicidal ideation can not only directly affect NSSI behavior,but also indirectly affect NSSI behavior through anxiety.

Alzheimer's disease (AD) is a neurodegenerative disease characterized by progressive memory deficits and cognitive decline. Previous studies of peripheral blood biomarkers in AD have been focused on alterations of β-amyloid (Aβ) and phosphorylated (p)-tau. This article reviews the research progress of new biomarkers, such as inflammatory factors, metabolic indicators, and non-coding RNA, in peripheral blood of AD in recent years, in order to provide references for AD diagnosis.

Radiotherapy (RT) is one of the most common treatments for cancer. However, intracellular glutathione (GSH) plays a key role in protecting cancer from radiation damage. Herein, we have developed a platelet membrane biomimetic nanomedicine (PMD) that induces double GSH consumption to enhance tumor radioimmunotherapy. This biomimetic nanomedicine consists of an external platelet membrane and internal organic mesoporous silica nanoparticles (MON) loaded with 2-deoxy-D-glucose (2-DG). Thanks to the tumor-targeting ability of the platelet membranes, PMD can target and aggregate to the tumor site, which is internalized by tumor cells. Within tumor cells overexpressing GSH, MON reacts with GSH to degrade and release 2-DG. This step initially depletes the intracellular GSH content. The subsequent release of 2-DG inhibits glycolysis and adenosine triphosphate (ATP) production, ultimately leading to secondary GSH consumption. This nanodrug combines dual GSH depletion, starvation therapy, and RT to promote immunogenic cell death and stimulate the systemic immune response. In the bilateral tumor model in vivo, distal tumor growth was also well suppressed. The proportion of mature dendritic cells (DC) and CD8⁺ T cells in the mice was increased. This indicates that PMD can promote anti-tumor radioimmunotherapy and has good prospects for clinical application.

Objective To investigate the relationship between serum sorting protein(Sortilin),trimethyl-amine oxide(TMAO)and inflammatory factors and abdominal aortic calcification(AAC)in maintenance he-modialysis(MHD)patients.Methods A total of 197 MHD patients(MHD group)admitted to Department of Nephrology in the hospital from January 2021 to May 2023 and 150 physically examined healthy individuals(control group)during the same period were prospectively selected,and the MHD patients were classified into the moderate and severe AAC group(82 patients)and no or mild AAC group(115 patients)according to the AAC score.The serum of serum Sortilin,TMAO and inflammatory factors[interleukin(IL)-1β,IL-6,tumor necrosis factor-α(TNF-α)]were measured using enzyme-linked immunosorbent assay.The correlation be-tween serum Sortilin,TMAO,and inflammatory factors in MHD patients was assessed using Spearman corre-lation analysis,and influencing factors associated with moderate and severe AAC in MHD patients were ex-plored using multivariate Logistic regression analysis.The predictive value of serum Sortilin and TMAO levels for moderate and severe AAC in MHD patients was analyzed using receiver operating characteristic curve.Re-sults The levels of serum Sortilin,TMAO,IL-1β,IL-6 and TNF-α in moderate and severe AAC group were higher than those in no or mild AAC group and control group(all P＜0.05).Serum Sortilin and TMAO were positively correlated with IL-1β,IL-6 and TNF-α levels in MHD patients(all P＜0.05).Prolonged dialysis age(OR=1.034,95％CI:1.010-1.060),increased levels of IL-6(OR=1.092,95％CI:1.034-1.152),Sortilin(OR=1.076,95％CI:1.043-1.110)and TMAO(OR=1.384,95％CI:1.150-1.664)were independent risk factors for moderate and severe AAC in MHD patients(P＜0.05).The area under the curve of serum Sortilin combined with TMAO levels in predicting moderate and severe AAC in MHD patients was 0.885(95％CI:0.831-0.926),which was greater than 0.785(95％CI:0.721-0.841)and 0.797(95％CI:0.734-0.850)predicted by serum Sortilin and TMAO levels alone(P＜0.05).Conclusion The levels of se-rum Sortilin and TMAO in MHD patients are increased,and are closely related to the elevation of inflammato-ry factors and AAC.Furthermore,the combination of serum Sortilin and TMAO levels shows certain predic-tive value for moderate and severe AAC in MHD patients.
