Chronic post-surgical pain (CPSP) is a common long-term complication following lung surgery. Its high incidence significantly impacts patients’ quality of life and functional recovery, and imposes a substantial socioeconomic burden. This consensus aims to systematically establish a standardized integrated Chinese and Western medicine diagnostic and treatment framework for chronic post-lung surgery pain (CPLSP). Based on the latest domestic and international evidence-based medical research and multidisciplinary clinical experience, the working group comprehensively elaborates on core issues regarding CPLSP, including its definition, epidemiology, pathogenesis, clinical assessment, Western medical treatment, traditional Chinese medicine (TCM) treatment, and integrated strategies. The consensus emphasizes a patient-centered approach, adhering to the principles of multimodality, individualization, and stepwise management, highlighting the synergistic advantages of integrating Chinese and Western medicine throughout the entire perioperative management cycle encompassing "perioperative anti-inflammation, acute analgesia, and chronic rehabilitation." Through systematic literature retrieval and evidence integration, a total of 9 core recommendations were established to provide scientifically sound and clinically practical guidance.

In the tumor microenvironment, a bidirectional feedback regulation exists between aberrant angiogenesis and antitumor immunity, which provides a basis for the synergistic effects of antiangiogenic therapy and immunotherapy. The underlying mechanisms include relief of immunosuppression mediated by proangiogenic factors, induction of vascular normalization to reshape the immune microenvironment, and formation of a positive immune-vascular feedback loop. Based on these mechanisms, the combination of antiangiogenic therapy and immunotherapy has demonstrated synergistic efficacy in advanced non-small cell lung cancer (NSCLC) and is gradually being moved forward to the neoadjuvant setting. However, in the perioperative treatment of resectable lung cancer, this regimen still faces challenges, including primary resistance, a brief window of vascular normalization, and an unclear understanding of spatial interaction mechanisms. This review systematically elucidates the synergistic mechanisms of antiangiogenic agents combined with immunotherapy in NSCLC and the latest advances of this combination strategy in the neoadjuvant therapy setting, aiming to provide a reference for clinical practice.

OBJECTIVE To screen a single matrix, prepare dissolving microneedles of Pterocarya hupehensis total flavonoids(PHTF-MN), and characterize it while evaluating its analgesic effects.METHODS Using microneedle morphology and puncture rate as evaluation indicators, the matrix was screened from polyvinyl alcohol (PVA), polyvinylpyrrolidone K30 (PVP K30), PVP K90, and sodium hyaluronate with relative molecular weights of 15 000 and 60 000 (HA 1.5w and HA 6w ). PHTF-MN was prepared by the layer-by-layer casting method with the selected matrix, and the appearance and morphology, total flavonoid content, mechanical properties, puncture performance, dissolution properties, and drug release behavior of the obtained PHTF-MN were characterized. Using male BALB/c mice as test subjects and aspirin (ASA) as a positive control, the analgesic effects of the microneedles were evaluated using a formalin-induced pain model.RESULTS Blank microneedles prepared with 30% HA 1.5w exhibited optimal surface flatness and the membrane puncture rate (through 4 layers of parafilm membrane) reaching 78%. The PHTF-MNs (with PHTF contents of 10, 20, 30, 40, and 50 mg/g in the matrix) exhibited uniform arrays and intact tips, with RSDs for total flavonoid contents all below 7% ( n =8). The single-needle puncture forces were 1.46 and 1.07 N (with PHTF contents of 30 and 50 mg/g in the matrix, respectively). The skin penetration rate approached 100%, with visible puncture marks in the stratum corneum and drug residue (with a PHTF content of 50 mg/g in the matrix). After 30 min of fixation, the needles had almost completely dissolved, and the skin retention rates all exceeded 90% (with PHTF contents of 10, 30, and 50 mg/g in the matrix, respectively). The cumulative release within 8 h was (134.64±2.03) μg/cm 2 , and the fit to the first-order kinetic equation ( R 2 =0.950 1) was highest (with a PHTF content of 50 mg/g in the matrix). Low- and high-dose PHTF-MN (containing 85.26 and 145.03 μg of total flavonoids per patch, respectively; 1 patch/day) significantly shortened the cumulative time of phase Ⅱ pain response in mice ( P <0.05), with pain inhibition rates (43.67% and 59.78%) comparable to those of ASA (53.70%).CONCLUSIONS PHTF-MN using HA 1.5w as a single matrix was successfully prepared. This formulation features a simplified preparation process, uniform drug loading, favorable mechanical properties, resistance to fracture, and rapid dissolution. Its drug release behavior conforms to a first-order kinetic model, and its analgesic effect is comparable to that of ASA.

ObjectiveTo enhance the genetic diagnostic yield for fetal short femur length (FL) and to evaluate the integration of whole exome sequencing (WES) with chromosomal abnormality detection in prenatal diagnosis. MethodsA total of 27 mid-to-late trimester fetuses diagnosed with short FL [FL < 5th percentile for gestational age or < -2 SD (Standard Deviation)] at the Prenatal Diagnosis And Medical Genetics Center,Shenshan Medical Center,Memorial Hospital of Sun Yat-Sen University between November 2023 and May 2025 were included. Amniotic fluid or umbilical cord blood samples were collected and subjected to chromosomal karyotyping (19cases), chromosomal microarray analysis (CMA) or low-coverage whole genome copy number variation(CNV-Seq) (27 cases), and trio-based whole exome sequencing (trio-WES) (27 cases). The pathogenicity of genetic variants were interpreted according to the American College of Medical Genetics and Genomics (ACMG) guidelines. ResultsTwenty-six genomic variants were detected in 17 of the 26 fetuses, including numerical chromosomal abnormalities (mosaic type), copy number variations (CNVs), single nucleotide variants (SNVs) and insertions-deletions (INDELs). Genomic variants detected in 11 cases could explain the short femur phenotype.The overall diagnostic rate was 11/27, with pathogenic/likely pathogenic variants explaining 9 cases and variants of uncertain significance (VUS) accounting for 1 cases. In addition Chromosomal karyotype analysis revealed chromosome mosaicism explaining 1 case. The diagnostic rate of CNV detection (CMA/CNV-seq) was 2/27, while WES achieved a diagnostic rate of 10/27, with an incremental yield of 8/27 in cases with negative or inconclusive CNV results. Pathogenic mutations involved genes such as FGFR3, SHOX, DUOX2, CLCN5, and HBA1/HBA2. ConclusionTrio-WES significantly improves the genetic diagnostic rate for fetal short femur length, particularly in cases where chromosomal analysis fails to identify a cause. Karyotyping remains valuable for detecting low-level mosaicism in large-scale chromosomal abnormalities, thereby complementing WES and CNV detection. A stepwise or parallel genetic testing strategy is recommended in prenatal diagnosis to optimize diagnostic efficiency and support clinical decision-making.

Objective:To evaluate the effect of acupuncture on postoperative delirium (POD) in diabetic patients undergoing surgery under general anesthesia.Methods:In this randomized controlled trial, 92 diabetic patients of either sex, aged 30-80 yr, with a body mass index of 18-28 kg/m 2, of American Society of Anesthesiologists Physical Status classification Ⅱ or Ⅲ, scheduled for elective surgery under general anesthesia, were divided into 2 groups ( n=46 each) using a table of random numbers: control group (group C) and acupuncture group (group A). Group A received acupuncture at the Baihui (GV20), Shenting (GV24) and Sishencong (EX-HN1) acupoints before anesthesia. The needles were retained for 30 min, with manual stimulation applied every 10 min for 10 s each time. After 4 stimulations, routine anesthesia was carried out. Group C received routine anesthesia only. Regional cerebral oxygen saturation was recorded on admission to the operating room (T 0), after anesthesia induction (T 1), at the start of surgery (T 2), at the end of surgery (T 3), and immediately after tracheal extubation (T 4). The POD developed within 3 days after surgery was assessed. The occurrence of needle-related adverse effects such as fainting, subcutaneous bleeding, and local paresthesia was recorded. Results:Compared with group C, the incidence of POD was significantly reduced, and the regional cerebral oxygen saturation was increased at T 1, 4 in group A ( P<0.05). Conclusions:Acupuncture can decrease the development of POD in diabetic patients undergoing surgery under general anesthesia, which is related to an increase in regional cerebral oxygen saturation.

Aim To explore the effect of hydroxysafflor yellow A(HSYA)on lipocalin 2(LCN2)-induced fer-roptosis in HT22 cells and the related mechanism.Methods Thirty male Sprague-Dawley(SD)rats were used to establish the middle cerebral artery occlu-sion/reperfusion(MCAO/R)model by the suture method.The rats were randomly divided into the Sham group,the MCAO/R group,and the MCAO/R+HSYA group.The infarct area was measured by TTC staining,and the degree of neurological deficit was evaluated by the Z-Longa scoring method.The expressions of LCN2 and 24P3R in brain tissues were detected by Western blot.LCN2 protein was added to HT-22 cells,and the cells were divided into the normal group,the LCN2 group,and the LCN2+HSYA group.The optimal con-centration of LCN2-induced neuronal ferroptosis was screened by LDH assay and Western blot,and the ex-pression levels of ferritin,FPN1,GPX4,SLC7A11,COX2,and 24P3R were detected.LCN2 was knocked down by siRNA transfection,and the expressions of GPX4 and ferritin were detected.The contents of glu-tathione(GSH),malondialdehyde(MDA),GPX4,and Fe2+were determined by colorimetry,and the expres-sion of GPX4 was detected by immunofluorescence.The binding force between HSYA and LCN2 was ana-lyzed by molecular docking technology.Results Ani-mal experiments showed that HSYA could reduce the cerebral infarction area and decrease the neurological function score of MCAO/R rats.Compared with the sham group,the levels of LCN2 and 24P3R increased in the MCAO/R group,while HSYA inhibited their ex-pressions.Cell experiments showed that the optimal concentration of LCN2 to induce ferroptosis in HT22 cells was 2 μmol·L-1.After knocking down LCN2 by siRNA transfection,compared with the LCN2 group,the expression levels of GPX4 and ferritin in the siLCN2 group increased significantly.Compared with the nor-mal group,the expressions of SLC7A11,GPX4,FPN1,ferritin,and GSH in the LCN2 group decreased signifi-cantly,while the concentration of Fe2+,and the expres-sions of MDA,COX2,and 24P3R increased.HSYA could increase the expressions of SLC7A11,GPX4,FPN1,ferritin,and GSH,reduce the contents of Fe2+and MDA,and inhibit the expressions of COX2 and 24P3R.Molecular docking showed that the binding en-ergy between HSYA and LCN2 was-8.0 kJ·mol-1.Conclusion HSYA can inhibit LCN2-induced ferrop-tosis in HT22 cells through the SLC7A11/GPX4 signa-ling pathway.

Objective:To investigate the prognostic value of deep learning-based automated quantification of tumor-stroma ratio (TSR) in patients undergoing neoadjuvant therapy (NAT) for breast cancer.Methods:Specimens were collected from 209 breast cancer patients who received NAT at Renmin Hospital of Wuhan University from October 2019 to June 2023. TSR levels in pre-NAT biopsy specimens were automatically computed using a deep learning algorithm and categorized into low stroma (TSR≤30%), intermediate stroma (TSR 30% to ≤60%), and high stroma (TSR>60%) groups. Residual cancer burden (RCB) grading of post-NAT surgical specimens was determined to compare the relationship between TSR expression levels and RCB grades. The correlation of TSR with NAT efficacy was analyzed, and the association between TSR expression and patient prognosis was further investigated.Results:There were 85 cases with low stroma (TSR≤30%), 93 cases with intermediate stroma (TSR 30% to ≤60%), and 31 cases with high stroma (TSR>60%). Different TSR expression levels showed significant differences between various RCB grades ( P<0.05). Logistic univariate and multivariate analyses showed that TSR was a risk factor for obtaining a complete pathological remission from neoadjuvant therapy for breast cancer when it was used as a continuous variable ( P<0.05); COX regression and survival analyses showed that the lower the percentage of tumorigenic mesenchyme was, the better the prognosis of the patient was ( P<0.05). Conclusions:The deep learning-based model enables automatic and accurate quantification of TSR. A lower pre-treatment tumoral stroma is associated with a lower RCB score and a higher rate of pathologic complete response, indicating that TSR can predict the efficacy of neoadjuvant therapy in breast cancer and thus holds prognostic significance. Therefore, TSR may serve as a biomarker for predicting therapeutic outcomes in breast cancer neoadjuvant therapy.
