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.

Objective To elucidate the molecular mechanism of sirtuin-3 (SIRT3) in regulating mitochondrial biogenesis in human renal tubular epithelial cells. Methods Cells were stimulated with different concentrations of H2O2 and divided into four groups: control (NC), 50 μmol/L H2O2, 110 μmol/L H2O2 and 150 μmol/L H2O2. SIRT3 protein expression was then measured. SIRT3 was knocked down with siRNA, and cells were further assigned to five groups: control (NC), negative-control siRNA (NCsi), SIRT3-siRNA (siSIRT3), NCsi+H2O2, and siSIRT3+H2O2. After 24 h, cellular adenosine triphosphate (ATP) and mitochondrial superoxide anion (O2•−) levels were determined, together with mitochondrial expression of SIRT3, peroxisome proliferator-activated receptor γ coactivator-1α (PGC-1α), nuclear respiratory factor 1 (NRF1), mitochondrial transcription factor A (TFAM), superoxide dismutase 2 (SOD2), acetylated-SOD2 and adenosine monophosphate activated protein kinase α1 (AMPKα1). Results The 110 and 150 μmol/L H2O2 decreased SIRT3 protein (both P<0.05). ATP and mitochondrial O2•− did not differ between NC and NCsi groups (both P>0.05). Compared to the NCsi group, the siSIRT3 group exhibited elevated O2•− level, decreased SIRT3 protein and increased expression levels of SOD2 and acetylated SOD2 protein (all P<0.05). Compared to the NCsi group, the NCsi+H2O2 group exhibited decreased cellular ATP levels, elevated mitochondrial O2•− levels, and reduced protein expression levels of SIRT3, SOD2, TFAM, AMPKα1, PGC-1α and NRF1 (all P<0.05). Compared with the siSIRT3 group, the siSIRT3+H2O2 group showed a decrease in cellular ATP levels, an increase in mitochondrial O2•− levels, a decrease in SIRT3, SOD2, TFAM, AMPKα1, PGC-1α and NRF1 protein expression levels and a decrease in acetylated SOD2 protein expression levels (all P<0.05). Compared with the NCsi+H2O2 group, the siSIRT3+H2O2 group showed a decrease in cellular ATP levels, an increase in mitochondrial O2•− levels, a decrease in SIRT3, AMPKα1, PGC-1α and NRF1, TFAM protein expression levels, and an increase in SOD2 and acetylated SOD2 protein expression levels (all P<0.05). Conclusions SIRT3 promotes mitochondrial biogenesis in tubular epithelial cells via the AMPK/PGC-1α/NRF1/TFAM axis, representing a key mechanism through which SIRT3 ameliorates oxidative stress-induced mitochondrial dysfunction.

OBJECTIVE To investigate the apoptosis-inducing effect of esculetin (Esc) on acute myeloid leukemia (AML) HL-60 cells by regulating the protein kinase B (AKT)/S-phase kinase-associated protein 2 (SKP2)/MutT homolog 1 (MTH1) pathway. METHODS AML HL-60 cells were randomly divided into control group (routine culture), Esc low-concentration group (L-Esc group, 25 μmol/L Esc), Esc medium-concentration group (M-Esc group, 50 μmol/L Esc), Esc high-concentration group (H-Esc group, 100 μmol/L Esc), and high-concentration of Esc+ SC79 (AKT agonist) group (100 μmol/L Esc+5 μmol/L SC79). Cell proliferation in each group was detected by MTT assay and colony formation assay. The level of reactive oxygen species (ROS) in cells was measured by using the CM-H2DCFDA fluorescent probe. Cell apoptosis was analyzed by flow cytometry. Western blot assay was performed to detect the expression levels of apoptosis-related proteins [B-cell lymphoma 2 (Bcl-2), Bcl-2-associated X protein (Bax), cleaved caspase-3], AKT/SKP2/MTH1 pathway-related proteins (p-AKT, AKT, SKP2, MTH1), along with the upstream and downstream proteins of AKT phosphatidylinositol 3-kinase (PI3K), cyclin-dependent kinase inhibitor 1 (P21) and cyclin-dependent kinase inhibitor 1B (P27). RESULTS Compared with control group, the cell viability, colony number, and the phosphorylation levels of AKT and PI3K proteins as well as protein expressions of SKP2, MTH1 and Bcl-2 were significantly decreased (P<0.05), while ROS level, apoptosis rate, and the expression levels of Bax, cleaved caspase-3, P21 and P27 proteins were significantly increased (P<0.05). Moreover, the effects of Esc exhibited concentration-dependence (P<0.05). Compared with H-Esc group, above indexes of high-concentration of Esc+ SC79 group were reversed significantly (P<0.05). CONCLUSIONS Esc may promote massive ROS production and induce activation of apoptosis in HL-60 cells by inhibiting the AKT/SKP2/MTH1 pathway, thus inhibiting the proliferation of HL-60 cells.

Objective To explore the clinical value of albumin-globulin ratio(AGR)combined with prostate-specific antigen(PSA)and Gleason score in predicting biochemical recurrence(BCR)after radical resection in patients with localized prostate cancer, and to provide reference for early identification of BCR high-risk patients and individualized treatment. Methods The clinical data of 114 patients with localized prostate cancer treated during Sep.2019 and Sep.2023 were retrospectively analyzed.According to postoperative BCR status, patients were divided into the BCR group(n=43)and non-BCR group(n=71).Preoperative clinical and pathological data were compared between the two groups.Univariate and multivariate Cox regression analyses were used to assess the correlation between these indicators and BCR.The predictive performance of the combined model was evaluated using receiver operating characteristic(ROC)curve.The Kaplan-Meier method was used to compare biochemical recurrence-free survival(BFS)among patients with different AGR, PSA levels and Gleason scores.Results Compared with the non-BCR group, the BCR group had significantly higher PSA level and ISUP grading, but significantly lower AGR level(P<0.001).Multivariate Cox regression analyses showed that AGR was negatively correlated with BCR(HR=0.031, 95%CI:0.008-0.119, P<0.001), PSA was positively correlated with BCR(HR=1.009, 95%CI:1.002-1.016, P=0.017), and Gleason score was positively correlated with BCR(HR=1.551, 95%CI:1.199-2.005, P<0.001).The area under the ROC curve(AUC)for the combined prediction model(AGR + PSA + Gleason score)was 0.886, with a sensitivity of 90.7% and a specificity of 78.9%.Kaplan-Meier analyses showed that patients in the low AGR group, high PSA group, and high Gleason score group had significantly lower BFS than those in the high AGR group, low PSA group and low Gleason score group, respectively(all P<0.0001).Conclusion The combination of AGR, PSA and Gleason score is closely associated with postoperative BCR in patients with localized prostate cancer.The combined prediction model demonstrates high predictive efficacy and can provide an important reference for the early identification of high-risk BCR patients and for guiding individualized postoperative treatment.

Objective To introduce the calculation of the DISO index in multi-dimensional data ranking for disease surveillance, and evaluate its applicability. Methods Using the data from the quality supervision and inspection of infectious disease reporting in Jingzhou City in a certain year as an example, the DISO index was used to rank 16 investigated medical institutions and compared with the TOPSIS method. The consistency between the two evaluation results was analyzed using Spearman correlation. Then, The DISO index from different medical institutions was used to evaluate the ranking of 8 counties (cities, districts). The evaluation indicators for the supervision and inspection included six items: report rate, timely report rate, completeness of report card filling, accuracy of report card filling, consistency rate with network information report, and completeness of valid ID number filling. Results Among the 16 medical institutions, 8 institutions had all six evaluation indicators at 100%. Using the two methods to rank the 16 medical institutions, the two methods showed that the 8 medical institutions with all six evaluation indicators at 100% were ranked first. There was a strong correlation between the rankings of the 16 medical institutions using the two methods (rs=0.992, P=0.000). The three counties (cities, districts) with all six evaluation indicators at 100% were all ranked first, while country G was ranked seventh and country E was ranked eighth. Conclusion The results of the DISO index and the TOPSIS method were similar in one-dimensional ranking. DISO can be used for multi-dimensional ranking of disease surveillance data and deserves to be promoted and applied.

ObjectivePhotoacoustic pump-probe imaging can effectively eliminate the interference of blood background signal in traditional photoacoustic imaging, and realize the imaging of weak phosphorescence molecules and their triplet lifetimes in deep tissues. However, background differential noise in photoacoustic pump-probe imaging often leads to large fitting results of phosphorescent molecule concentration and triplet lifetime. Therefore, this paper proposes a novel triplet lifetime fitting method for photoacoustic pump-probe imaging. By extracting the phase of the triplet differential signal and the background noise, the fitting bias caused by the background noise can be effectively corrected. MethodsThe advantages and feasibility of the proposed algorithm are verified by numerical simulation, phantom and in vivo experiments, respectively. ResultsIn the numerical simulation, under the condition of noise intensity being 10% of the signal amplitude, the new method can optimize the fitting deviation from 48.5% to about 5%, and has a higher exclusion coefficient (0.88>0.79), which greatly improves the fitting accuracy. The high specificity imaging ability of photoacoustic pump imaging for phosphorescent molecules has been demonstrated by phantom experiments. In vivo experiments have verified the feasibility of the new fitting method proposed in this paper for fitting phosphoometric lifetime to monitor oxygen partial pressure content during photodynamic therapy of tumors in nude mice. ConclusionThis work will play an important role in promoting the application of photoacoustic pump-probe imaging in biomedicine.

Objective:To establish a quality standard system for Descurainiae Semen under the requirements of German Pharmaceutical Codex (DPC); To compare the similarities and differences between DPC and the Pharmacopoeia of the People's Republic of China regarding the establishment of a quality standard system for TCM medicinal materials. Methods:Based on the requirements of DPC, and referring to the relevant methods of Pharmacopoeia of the People's Republic of China, the quality of 30 batches of Descurainiae Semen samples were assessed by observing the appearance and microscopic characteristics and determining their loss on drying, total ash content, and ash insoluble in hydrochloric acid. A TLC identification method was established based on a silica gel G TLC plate, using a developing agent composed of ethyl acetate, formic acid, and water in the ratio of 7:1.5:2.5 ( V/ V/ V). The method utilized rutin and quercetin as indicators for the System Suitability Test (SST), and took quercetin-3-O-β-D-glucose-7-O-β-D-gentiobioside and isorhamnetin 3-O-β-D-glucose-7-O-β-D-gentiobioside as the index. Based on the content determination method for Descurainiae Semen in the Pharmacopoeia of the People's Republic of China, a content determination method was established with quercetin-3-O-β-D-glucose-7-O-β- D-gentiobioside as the index. Results:The loss on drying for the 30 batches of samples ranged from 6.15% to 12.0%, with the total ash content ranged from 3.17% to 9.44%, and the ash insoluble in hydrochloric acid content ranged from 0.14% to 4.82%. The resolution of rutin and quercetin met the DPC's requirements for the SST criteria in TLC identification, and all batches of samples showed good separation of the index components. This method could effectively distinguish Descurainiae Semen from Lepidii Semen. Using modern chromatographic and spectroscopic techniques, the structure of the chromatographic peak adjacent to the component of the index (quercetin-3-O-β- D-glucoside-7-O-β-D-gentiobioside) was identified as descuraic anhydride B. The resolution between the two components in all batches of samples was greater than 3.1, which met the DPC's requirements for the SST criteria in content determination. The results of the methodological investigations met the requirements for content determination. The content of quercetin-3-O-β- D-glucose-7-O-β-D-gentiobioside in 30 batches of samples ranged from 0.062%-0.125%.Conclusion:The established quality standard system for Descurainiae Semen in this article is comprehensive, and meets the requirements of the DPC, which can be used for the quality control of Descurainiae Semen.

Objective:
To study the effect of metformin sensitizing pancreatic cancer cells with radiotherapy, with a focus on elucidating the underlying mechanisms of radiotherapy resistance. In particular, the role of the PERK/P-eIF2/ATF4 signaling pathway in mediating these effects was preliminarily explored.
Methods :
Pancreatic cancer cell lines(PANC-1 and PANC-2) were categorized into control, radiotherapy, and drug treatment groups. Following the respective treatments, cell proliferation inhibition was assessed using the CCK-8 assay, colony formation assays, and cell death staining. Senescence was quantified by β-galactosidase(SA-β-Gal) staining. The expression of cell cycle regulators(P21, P16, γ-H2AX), apoptosis markers(Bax, Bcl-2, Cleaved caspase-3), and pathway-related proteins(PERK, P-eIF2, ATF4) was evaluated by Western blot and immunofluorescence. To further investigate the role of the PERK/P-eIF2/ATF4 axis in metformin-mediated modulation of pancreatic cancer cell senescence and radiosensitization, selective inhibitors(GSK2606414) and agonists(MK-28) of PERK were employed.
Results :
Radiotherapy markedly upregulated senescence-associated markers(P21, P16, γ-H2AX, and β-galactosidase activity) in pancreatic cancer cells. Senescent cells exhibited enhanced proliferative activity and increased tumor volume both in vitro and in vivo. Metformin mitigated radiotherapy-induced senescence by reducing the expression of senescence markers and significantly suppressing the clonogenic and proliferative capacity of treated cells. Mechanistically, radiotherapy activated the PERK signaling pathway, leading to increased expression of PERK, P-eIF2, and ATF4, thereby driving cellular senescence. Pharmacological inhibition of PERK reduced β-galactosidase activity, while PERK activation further promoted the expression of senescence-associated proteins—an effect that was reversed by metformin.
Conclusion
Metformin inhibits the activation of the PERK/P-eIF2/ATF4 signaling pathway in pancreatic cancer cells following radiotherapy, thereby delaying cellular senescence and reducing the associated radiotherapy resistance of senescent cells. This modulation contributes to the sensitization of pancreatic cancer cells to radiotherapy.
