It is very limited that the benefit of perioperative chemotherapy in early non-small cell lung cancer (NSCLC), and the 5-year survival rate is only 5% higher than surgery. Antibodies that block programmed cell death protein 1/programmed death-ligand 1 significantly improve the survival of advanced NSCLC. The value of immunotherapy in early NSCLC is also being explored. This paper firstly summarized and analyzed the progress of immunotherapy in the perioperative period of NSCLC. Secondly, the safety and feasibility of surgical resection after neoadjuvant immunotherapy were discussed. Finally, the clinical value of different therapeutic efficacy prediction indicators was summarized, in order to clarify the current status of immunotherapy in the perioperative period, so as to improve the clinical benefits of early NSCLC patients.

Objective: To evaluate the diagnostic performance of magnetic resonance spectroscopy (MRS) in discriminating fumarate hydratase-deficient (FH-d) uterine leiomyomas (ULs) from FH-preserved ULs. Materials and Methods: This study consisted of three stages, with independent cohorts recruited for each stage: 1) sample-size estimation was retrospectively performed on UL specimens (diameter ≥3 cm; age, 20–40 years) from our database with immunohistochemistry (IHC) for 2-succinocysteine (2-SC) as the reference, without genetic testing, 2) MRS sequence optimization in confirmed FH germline mutation participants with ultrasound-detected ULs (diameter ≥3 cm), without IHC analysis, and 3) prospective diagnostic test accuracy was evaluated in consecutive participants with ultrasound-detected ULs (diameter ≥3 cm;age, 20–40 years), using IHC for 2-SC for determining the FH status and subsequent genetic testing in those with positive 2-SC results to identify whether FH mutations were germline or somatic in origin. The choline and fumarate peaks in MRS were classified as positive, negative, or technical failure (TF). TFs were analyzed separately and excluded from the primary diagnostic accuracy calculations. T1-, T2-, and diffusion-weighted images were interpreted as hyperintense or hypointense. The enhancement rate and apparent diffusion coefficient were also acquired. Diagnostic performance was compared between MRS and various magnetic resonance imaging (MRI) features. Results: The optimal MRS parameters for the fumarate peak were echo time (TE) = 140 ms and an average of 256. Among the 360 prospective participants, 37 were confirmed to have FH-dULs. MRS showed positive fumarate peaks in 35 of 37 FH-dULs.After excluding six TFs, the positive fumarate peak on MRS showed 94.6% (35/37) sensitivity, 99.7% (316/317) specificity, and 99.2% (351/354) accuracy, all of which were significantly superior to those of other MRI features (P ≤ 0.002). Conclusion A positive fumarate peak on MRS may be a useful imaging biomarker for diagnosing FH-dULs.

Objective To explore the safety and feasibility of 5G remote robot-assisted thoracoscopic anatomic lobectomy and segmentectomy. Methods A retrospective analysis was conducted on patients who underwent 5G remote robot-assisted thoracoscopic anatomic lobectomy or segmentectomy between July and September 2024. The surgeries were performed collaboratively by Shanghai Chest Hospital, Affiliated Hospital of Yangzhou University, and The First Affiliated Hospital of Nanchang University. Perioperative outcomes were recorded and analyzed. Results Ten patients were included, comprising 4 anatomic lobectomies and 6 segmentectomies. The median age was 61.0 (56.0, 72.0) years. The median intraoperative bi-directional network latency was 52.5 (39.0, 54.0) ms. There were no instances of network interruption, robot-related adverse events, or conversions to open thoracotomy. The median postoperative chest tube drainage volume was 500.0 (375.0, 600.0) mL, and the median hospital stay was 5.5 (4.0, 6.0) days. No complications of Clavien-Dindo grade Ⅱor higher occurred. All patients were recurrence-free and alive during the 6-month postoperative follow-up period. Conclusion 5G remote robot-assisted thoracoscopic surgery demonstrates high safety and operational stability. This technology shows promising potential for clinical application and is worthy of further development and utilization.

Non-small cell lung cancer (NSCLC) is the leading cause of cancer-related deaths worldwide. Although surgery can cure some early-stage resectable patients, the postoperative recurrence rate remains as high as 30%-55%. Perioperative immune checkpoint inhibitor (ICI) therapy, which includes "neoadjuvant" therapy before surgery and "adjuvant" therapy after surgery, has significantly improved survival outcomes in resectable NSCLC patients. Large clinical studies, such as Checkmate 816, have demonstrated the superiority of neoadjuvant ICIs combined with chemotherapy in increasing the pathological complete response rate (pCR) and prolonging event-free survival (EFS). However, even with these advanced treatments, some patients do not achieve long-term benefits and experience early recurrence. This paper reviews the latest research progress of perioperative ICIs in NSCLC treatment, particularly the effectiveness of neoadjuvant chemoimmunotherapy in improving pCR and extending EFS. It further explores the recurrence patterns, resistance mechanisms, and potential biomarkers in NSCLC patients after neoadjuvant immunotherapy. By integrating basic research and clinical data, we analyze the mechanisms of early recurrence following perioperative immunotherapy and discuss future research directions and therapeutic strategies, providing new insights into precision treatment and recurrence prevention for NSCLC patients.

"Spirit turns but does not reverse； if it reverses， it ceases to turn" originates from the Plain Questions： Discussion on Essential Jade Plates （《素问·玉版论要篇》）. It profoundly summarizes the objectivity of life as a phenomenon subject to the laws of the universe and nature， while also expressing the subjectivity of individuals possessing systematic， stable， and ordered biological rhythms. In light of relevant ancient philosophical insights， the theory of "spirit turns but does not reverse； if it reverses， it ceases to turn" embodies the principles of constant motion in life， change according to dao （道）， orderly progression， and the rule that reversal disrupts continuity. In clinical diagnosis and treatment， one should adopt the therapeutic principle of regulating spirit to promote "spirit turning". Guiding along the trend and acting in accordance with the natural momentum must be adopted to maintain the operation of spirit turning. Adhering to constancy while recognizing variability， and prioritizing harmony above all， should be employed to ensure the orderly progress of spirit turning. Regulating qi movement serves as the driving force behind facilitating spirit turning. This will provide clinical insights and theoretical foundations for treating diseases through the concept of "regulating spirit".
