Surgical treatment is one of the key approaches for non-small cell lung cancer (NSCLC). Regular postoperative follow-up is crucial for early detection and timely management of tumor recurrence, metastasis, or second primary tumors. A scientifically sound and reasonable follow-up strategy not only extends patient survival but also significantly improves quality of life, thereby enhancing overall prognosis. This consensus aims to build upon the previous version by incorporating the latest clinical research advancements and refining postoperative follow-up protocols for early-stage NSCLC patients based on different treatment modalities. It provides a scientific and practical reference for clinicians involved in the postoperative follow-up management of NSCLC. By optimizing follow-up strategies, this consensus seeks to promote the standardization and normalization of lung cancer diagnosis and treatment in China, helping more patients receive high-quality care and long-term management. Additionally, the release of this consensus is expected to provide insights for related research and clinical practice both domestically and internationally, driving continuous development and innovation in the field of postoperative management for NSCLC.

Objective: To clarify the specific mechanisms of action of raw Phellodendron chinense Schneid. (RPC) and saltwater-processed PC (SPC) in the treatment of rats with a kidney-yin deficiency pattern (KYDP). Methods: Healthy rats were administered hydrocortisone to establish a KYDP model. The rats were divided into seven groups: blank control, model, positive control (Liuwei Dihuang pills), high-dose RPC, low-dose RPC, high-dose SPC, and low-dose SPC. Enzyme-linked immunosorbent assay was used to measure the levels of cAMP, cGMP, TRH, TSH, T3, T4, IFN-γ, TNF-α, and testosterone in the serum and the levels of Na+-K+-ATPase and Ca2+-Mg2+-ATPase in the liver. TRH mRNA expression in the rat hypothalamus was measured using RT-PCR. THRα1+2 protein expression in the hypothalamus of rats was measured using Western blot. Immunohistochemistry was performed to determine the expression levels of FAS, FasL, and TSHR. Flow cytometry was used to determine CD4+ and CD8+ T lymphocyte levels. Illumina MiSeq sequencing technology was used to evaluate the diversity of intestinal flora in KYDP rats. Results: The cAMP/cGMP ratio was significantly higher in the model group than in the blank control group (P = .048). Compared with the model group, after administration, the levels of the above-mentioned serum and liver indexes decreased, except that of testosterone. The CD4+/CD8+ ratio also decreased. Compared with the RPC group, the levels of T3, IFN-γ, FAS, FasL, and TSHR in the SPC group decreased whereas that of testosterone increased. Additionally, immune function and intestinal flora diversity improved in the SPC group. SPC proved to be more effective in improving liver energy metabolism in KYDP rats than RPC. Conclusion SPC had a better therapeutic effect on KYDP than RPC. The underlying mechanism of action may be related to improvements in liver energy metabolism, immune function, and intestinal flora diversity.

Objective:To investigate the safety and efficacy of intravascular intervention in ruptured intracranial vertebral artery dissecting aneurysm (IVADA).Methods:A retrospective analysis was performed; 25 patients with ruptured IVADA (25 aneurysms) admitted to Department of Neurosurgery, First Affiliated Hospital of University of Science and Technology of China from January 2020 to June 2023, were chosen. Aneurysm and parent artery occlusion or stent-assisted spring coil embolization were performed according to location of the aneurysms, degrees of aneurysm immediate embolization were evaluated by Raymond grading, and perioperative adverse events were recorded. The patients were followed up for 6-48 months, and aneurysm recurrence was determined according to DSA results; prognoses were assessed by modified Rankin Scale (mRS), with scores of 0-2 as good prognosis and scores of 3-6 as poor prognosis.Results:All 25 patients had unilateral ruptured IVADA, 10 (40%) received aneurysm and parent artery occlusion (occlusion of dissection segment) and 15 (60%) received stent-assisted embolization. Immediately after surgery, 19 patients (76%) had grading I embolization, 4 (16%) grading II embolization, and 2 (8%) grading III embolization. No aneurysm rupture or stent related thrombosis was observed during procedure; 3 patients (12%) died after procedure, with postoperative rebleeding in 1, postoperative cerebellar infarction with respiratory failure in 1, and severe pneumonia in 1. In the 22 survivals, 18 had good prognosis and 4 had poor prognosis. In the 5 relapsed patients (all accepted stent-assisted embolization), 4 underwent re-intervention, and one with visualization at aneurysm neck was relatively stable on re-examination and accepted regular follow up.Conclusion:Aneurysm and parent artery occlusion can be used for non-dominant vertebral artery aneurysms not involving posterior inferior cerebellar artery, whose recurrence rate is lower than that of stent-assisted coil embolization.

Objective:To evaluate the effect of the impaction of posterior wall on the prognosis following open reduction and internal fixation for fractures of acetabular posterior wall.Methods:A retrospective study was conducted to analyze the data from the 83 patients with fracture of acetabular posterior wall who had been consecutively treated by open reduction and internal fixation at Department of Orthopaedics and Traumatology, Beijing Jishuitan Hospital from January 2017 to December 2020. The patients were divided into 2 groups based on involvement of posterior wall impaction. In the impaction group of 33 cases, there were 26 males and 7 females with an age of (47.4±11.6) years; in the non-impaction group of 50 cases, there were 43 males and 7 females with an age of (41.3±12.0) years. The quality of postoperative fracture reduction, the function of the affected hip at the last follow-up, and the complication rate during follow-up were compared between the 2 groups. Multifactorial binary logistic regression and age subgroups were used to analyze the effects of posterior wall impaction on functional outcomes.Results:The age, rate of associated injuries in other body parts, and rate of posterior wall comminution in the impaction group were significantly higher than those in the non-impaction group ( P<0.05), but there was no statistically significant difference in other general data of patients between the 2 groups ( P>0.05). All patients were followed up for (44.5±13.3) months after surgery. The rate of anatomical reduction in the non-impaction group (96.0%, 48/50) was significantly higher than that in the impaction group (57.6%, 19/33) ( P<0.05), and the good and excellent rate by the modified Merle d'Aubigné & Postel scale at the last follow-up in the non-impaction group (84.0%, 42/50) was significantly higher than that in the impaction group (51.5%, 17/33) ( P<0.05). There was no significant difference in the incidence of complications between the 2 groups ( P>0.05). After adjusting for age and gender, the difference in hip function was still significantly different between the 2 groups ( OR=0.23, 95% CI: 0.06 to 0.79, P=0.020). The effect of posterior wall impaction on functional outcomes was statistically significant in patients aged &ge;50 years ( P=0.008), whereas the difference was not statistically significant in patients aged <50 years ( P=0.194). Conclusions:Compared with non-impaction ones, acetabular fractures of posterior wall impaction tend to lead to poorer quality of reduction, which in turn affects the postoperative recovery of hip joint function. The impact of impaction fractures on functional recovery is more significant in patients aged 50 years and above.

Objective:To evaluate the effect of individualized positive end-expiratory pressure (PEEP) titration based on open-lung strategy on the intraoperative thoracic fluid content (TFC) in elderly patients undergoing transurethral ultrasound-guided laser-induced prostatectomy (TULIP).Methods:Eighty-six American Society of Anesthesiologists Physical Status classification Ⅱ or Ⅲ, patients, aged 65-80 yr, with body mass index of 18-28 kg/m 2, scheduled for elective TULIP, were divided into 2 groups ( n=43 each) by the random number table method: fixed PEEP group (group C) and individualized PEEP titration group (group P). PEEP was set at 4 cmH 2O after routine mechanical ventilation in group C. Patients underwent pulmonary recruitment maneuvers combined with individualized PEEP titration during surgery in group P. TFC was measured using a non-invasive cardiac output monitor at 5 min after tracheal intubation (T 0), 30 min after PEEP titration and ventilation (T 1), 5 min before surgery (T 2), and 5 min before leaving the recovery room (T 3). Cardiac output, oxygenation index and stroke volume index were recorded from T 0-T 2, arterial blood gas analysis was simultaneously performed to record peak airway pressure and dynamic lung compliance, and oxygenation index was calculated. The duration of postanesthesia care unit stay, pulmonary complications within 7 days after surgery, and length of hospital stay were also recorded. Results:Eighty-three patients were finally included, with 42 in group C and 41 in group P. Compared with group C, TFC was significantly decreased at T 1-T 3, cardiac index, cardiac output and stroke volume index were decreased at T 1, dynamic lung compliance, PaO 2 and oxygenation index were increased at T 1 and T 2, PaCO 2 was decreased, the incidence of postoperative pulmonary complications was reduced, and the duration of postanesthesia care unit stay and postoperative length of hospital stay were shortened in group P ( P<0.05). Conclusions:Individualized PEEP titration based on open-lung strategy can effectively decrease TFC and improve intraoperative oxygenation and prognosis in elderly patients undergoing TULIP.

Objective: To analyze the safety and effectiveness of different types of stents with the treatment of vertebraebasilar artery dissection aneurysms(VBADA). Methods : The clinical data of 80 patients with VBADA treated by intravascular intervention in the First Hospital of University of Science and Technology of China(Anhui Provincial Hospital) from February 2018 to November 2023 were retrospectively analyzed. Patients were divided into laser engraved stent group(n=34) and braided stent group(n=46) based on the type of stent used. O′Kelly-Marotta(OKM) grade was used to evaluate the embolization effect of aneurysms in DSA images, and a modified Rankin Scale(mRS) score was used to evaluate the clinical prognosis of patients. The baseline data, aneurysm characteristics, intraoperative and perioperative treatment details and postoperative follow-up details between the two groups were compared. Results : There was no significant difference in baseline data, mRS score, ischemic and hemorrhage complications and mortality between the two groups(allP>0.05). Compared with the laser engraved stent group, the mean diameter of aneurysms was larger(P<0.000 1) and the proportion of ruptured aneurysm(P<0.01), parent artery stenosis and beaded vascular lesions(P<0.05) and branch artery dissecting aneurysm were higher(P<0.01) in the braided stent group. Conversely, the proportion of coil-assisted embolization(P<0.000 1) and the immediate aneurysm occlusion rate(OKM C and D)(P<0.000 1) were lower. Finally, 21 patients were obtained by controlling for maximum diameter of aneurysms and whether coil-assisted embolization, the aneurysm occlusion rate half a year later in the braided stent group was higher than that in the laser engraved stent group(P<0.05), but the recurrence rate of postoperative aneurysm was lower than that of laser engraved stent group(P<0.05). It was worth noting that the cure rate and vascular remodeling rate of middle-large size VBADA which the maximum diameter being over 15 mm in the braided stent group reached 72.2%, and the whole effect was ideal. Conclusion Braided stents are relatively safe and effective in the treatment of VBADA and are significantly better than laser engraved stents in reducing VBADA recurrence and remodeling lesion vessels without increasing postoperative complication.

Objective This study aimed to evaluate whether the onset of the plateau phase of slow hepatitis B surface antigen decline in patients with chronic hepatitis B treated with intermittent interferon therapy is related to the frequency of dendritic cell subsets and expression of the costimulatory molecules CD40,CD80,CD83,and CD86. Method This was a cross-sectional study in which patients were divided into a natural history group(namely NH group),a long-term oral nucleoside analogs treatment group(namely NA group),and a plateau-arriving group(namely P group).The percentage of plasmacytoid dendritic cell and myeloid dendritic cell subsets in peripheral blood lymphocytes and monocytes and the mean fluorescence intensity of their surface costimulatory molecules were detected using a flow cytometer. Results In total,143 patients were enrolled(NH group,n = 49;NA group,n = 47;P group,n = 47).The results demonstrated that CD141/CD1c double negative myeloid dendritic cell(DNmDC)/lymphocytes and monocytes(%)in P group(0.041[0.024,0.069])was significantly lower than that in NH group(0.270[0.135,0.407])and NA group(0.273[0.150,0.443]),and CD86 mean fluorescence intensity of DNmDCs in P group(1832.0[1484.0,2793.0])was significantly lower than that in NH group(4316.0[2958.0,5169.0])and NA group(3299.0[2534.0,4371.0]),Adjusted P all<0.001. Conclusion Reduced DNmDCs and impaired maturation may be associated with the onset of the plateau phase during intermittent interferon therapy in patients with chronic hepatitis B.

Objective To investigate the role and underlying mechanisms of WD repeat domain 82(WDR82)protein in the pathogenesis and progression of glioma.Methods We analyzed the expression level of WDR82 in glioma tissues using GEPIA and UALCAN databases and further assessed WDR82 protein expression in glioma and adjacent normal tissues through immunohistochemical staining.The correlation between WDR82 expression and the prognosis of glioma patient was evaluated using Kaplan-Meier plotter.Experiments were conducted on A172 and U251 cell lines,which were categorized into four groups:control group(transfected with 3 μg pcDNA3),shR-control group(transfected with 3 μg pSilencer 2.1-U6),pWDR82 group(transfected with 3 μg pWDR82),and shR-WDR82 group(transfected with 3 μg shR-WDR82).Post-transfection,we confirmed transfection efficiency at 48 hours using qRT-PCR and measured cell viability at the same time point with CCK-8 assay.Clone formation assay was employed to assess cell proliferation capacity after 14 days of transfection,while flow cytometry was utilized to analyze cell apoptosis after 48 hours of transfection.Additionally,Western blotting was conducted to determine the expression levels of proteins related to proliferation and Akt/mTOR signaling pathway after 48 hours of transfection.Finally,the effect of WDR82 on tumor growth in NOD-SCID mice was investigated using tumor carrying experiment in vivo.Results Analysis of WDR82 expression in glioma tissues using GEPIA and UALCAN databases,along with immunohistochemical staining,revealed significantly higher expression levels compared to normal and paracancerous tissues(P＜0.05).Additionally,WDR82 expression was not associated with gender or age of patients(P＞0.05).Kaplan-Meier plotter analysis indicated that elevated WDR82 expression correlated with a poor prognosis in glioma patients(log-rank P=0.029).Overexpression of WDR82 notably enhanced the proliferation and inhibited the apoptosis of A172 and U251 cells,and also significantly upregulated the expression of MKI67,BCL2,CCND1,p-Akt and p-mTOR in A172 and U251 cells(P＜0.05).Conversely,WDR82 knockdown had the opposite effects,inhibiting cell proliferation,increasing apoptosis and downregulating the expression of MKI67,BCL2,CCND1,p-Akt and p-mTOR(P＜0.05).WDR82 knockdown in U251 cells significantly inhibited tumor growth in NOD-SCID mice(P＜0.05).Conclusion High expression of WDR82 promotes the proliferation of glioma cells and the growth of tumors in vivo by regulating the AKT/mTOR signaling pathway.

Objective:To explore the correlation between hip muscle factors measured with CT imaging and recovery of independent mobility within 1 year after surgery in elderly patients with hip fractures.Methods:A prospective cohort study was conducted on the clinical data of 680 elderly patients with hip fractures admitted to Beijing Jishuitan Hospital of Capital Medical University from November 2018 to December 2019. The patients were assigned to dependent group and assistant group according to whether they regained pre-injury independent mobility within 1 year after surgery. Gender, age, body mass index, personal history, living habits, past diseases, Charlson comorbidity index, laboratory test indicators, fracture types, anesthesia types, surgical methods, rehabilitation training, time from injury to surgery, and hip muscle parameters in both groups were recorded. OsiriX software was employed in the measurement of the hip muscles to measure the muscle area and density of the gluteus maximus and gluteus medius/minimus on CT images, and the average values were calculated as hip muscle area and density. Then the variables of hip muscle area and density were converted seperately to gender-normalized Z-scores, and were divided into high-area group ( Z&ge;0) and low-area group ( Z<0), and high-density group ( Z&ge;0) and low-density group ( Z<0) respectively. Observable variables were primarily analyzed using univariate analysis between the independent group and assistant group. Those variables with statistically significant differences in the univariate analysis or would potentially affect mobility recovery according to previous researches although there were no statistical significance were included in a multivariate Logistic regression analysis. Three Logistic regression models were designed (Model 1 uncorrected, Model 2 corrected for gender, age and body mass index, Model 3 corrected for variables in Model 2 and other variables included after above-mentioned analysis) to analyze whether muscle parameters were risk factors for recovery of independent mobility. Additionally, generalized estimating equations were used for repeated measurement to analyze the correlation between hip muscle area and recovery of independent mobility after surgery. Results:Compared to the assistant group, the independent group were younger in age, with lower rate of living alone, being housebound, cognitive impairment, and Charlson comorbidity index, lower level of hemoglobin and albumin, higher rate of femoral neck fractures, lower rate of internal fixation, shorter time from injury to surgery, larger hip muscle area, and higher hip muscle density ( P<0.05 or 0.01). Multivariate Logistic regression analysis showed that, in the fully corrected Model 3, only hip muscle area remained significantly correlated with recovery of independent mobility ( P<0.05), while no significant difference was found between the high-density group and low-density group ( P>0.05). In the repeated measurement, patients in the high-area group were 1.84 times more likely to restore independent mobility than those in the low-area group ( OR=1.84, 95% CI 1.33, 2.53, P<0.01). Conclusions:Hip muscle area measured with CT imaging is closely correlated to the recovery of independent mobility within 1 year after surgery in elderly patients with hip fractures. Moreover, larger hip muscle area indicates a larger likelihood of recovery of independent mobility.

This study aimed to investigate the effect of treadmill exercise on neuropathic pain and to determine whether mitophagy of the anterior cingulate cortex (ACC) contributes to exercise-mediated amelioration of neuropathic pain. Chronic constriction injury of the sciatic nerve (CCI) was used to establish a neuropathic pain model in Sprague-Dawley (SD) rats. Von-Frey filaments were used to assess the mechanical paw withdrawal threshold (PWT), and a thermal radiation meter was used to assess the thermal paw withdrawal latency (PWL) in rats. qPCR was used to evaluate the mRNA levels of Pink1, Parkin, Fundc1, and Bnip3. Western blot was used to evaluate the protein levels of PINK1 and PARKIN. To determine the impact of the mitophagy inducer carbonyl cyanide m-chlorophenylhydrazone (CCCP) on pain behaviors in CCI rats, 24 SD rats were randomly divided into CCI drug control group (CCI+Veh group), CCI+CCCP low-dose group (CCI+CCCP0.25), CCI+CCCP medium-dose group (CCI+CCCP2.5), and CCI+CCCP high-dose group (CCI+CCCP5). Pain behaviors were assessed on 0, 1, 3, 5, and 7 days after modeling. To explore whether exercise regulates pain through mitophagy, 24 SD rats were divided into sham, CCI, and CCI+Exercise (CCI+Exe) groups. The rats in the CCI+Exe group underwent 4-week low-moderate treadmill training one week after modeling. The mechanical pain and thermal pain behaviors of the rats in each group were assessed on 0, 7, 14, 21, and 35 days after modeling. Western blot was used to detect the levels of the mitophagy-related proteins PINK1, PARKIN, LC3 II/LC3 I, and P62 in ACC tissues. Transmission electron microscopy was used to observe the ultrastructure of mitochondrial morphology in the ACC. The results showed that: (1) Compared with the sham group, the pain thresholds of the ipsilateral side of the CCI group decreased significantly (P < 0.001). Meanwhile, the mRNA and protein levels of Pink1 were significantly higher, and those of Parkin were lower in the CCI group (P < 0.05). (2) Compared with the CCI+Veh group, each CCCP-dose group showed higher mechanical and thermal pain thresholds, and the levels of PINK1 and LC3 II/LC3 I were elevated significantly (P < 0.05, P < 0.01). (3) The pain thresholds of the CCI+Exe group increased significantly compared with those of the CCI group after treadmill intervention (P < 0.001, P < 0.01). Compared with the CCI group, the protein levels of PINK1 and P62 were decreased (P < 0.001, P < 0.01), and the protein levels of PARKIN and LC3 II/LC3 I were increased in the CCI+Exe group (P < 0.01, P < 0.05). Rod-shaped mitochondria were observed in the ACC of CCI+Exe group, and there were little mitochondrial fragmentation, swelling, or vacuoles. The results suggest that the mitochondrial PINK1/PARKIN autophagy pathway is blocked in the ACC of neuropathic pain model rats. Treadmill exercise could restore mitochondrial homeostasis and relieve neuropathic pain via the PINK1/PARKIN pathway.
