Lung cancer is the most common malignant tumor worldwide, ranking first in both incidence and mortality rates. According to the latest statistics from the International Agency for Research on Cancer (IARC), approximately 2.5 million new cases and around 1.8 million deaths from lung cancer occurred in 2022, placing a tremendous burden on global healthcare systems. The high mortality rate of lung cancer is closely linked to its subtle early symptoms, which often lead to diagnosis at advanced stages. This not only complicates treatment but also results in substantial economic losses. Current treatment options for lung cancer include surgery, radiotherapy, chemotherapy, targeted drug therapy, and immunotherapy. Among these, immunotherapy has emerged as the most groundbreaking advancement in recent years, owing to its unique antitumor mechanisms and impressive clinical benefits. Unlike traditional therapies such as radiotherapy and chemotherapy, immunotherapy activates or enhances the patient’s immune system to recognize and eliminate tumor cells. It offers advantages such as more durable therapeutic effects and relatively fewer toxic side effects. The main approaches to lung cancer immunotherapy include immune checkpoint inhibitors, tumor-specific antigen-targeted therapies, adoptive cell therapies, cancer vaccines, and oncolytic virus therapies. Among these, immune checkpoint inhibitors and tumor-specific antigen-targeted therapies have received approval from the U.S. Food and Drug Administration (FDA) for clinical use in lung cancer, significantly improving outcomes for patients with advanced non-small cell lung cancer. Although other immunotherapy strategies are still in clinical trials, they show great potential in improving treatment precision and efficacy. This article systematically reviews the latest research progress in lung cancer immunotherapy, including the development of novel immune checkpoint molecules, optimization of treatment strategies, identification of predictive biomarkers, and findings from recent clinical trials. It also discusses the current challenges in the field and outlines future directions, such as the development of next-generation immunotherapeutic agents, exploration of more effective combination regimens, and the establishment of precise efficacy prediction systems. The aim is to provide a valuable reference for the continued advancement of lung cancer immunotherapy.

BACKGROUND: Biomarkers-based prediction of long-term risk of acute coronary syndrome (ACS) is scarce. We aim to develop a risk score integrating clinical routine information (C) and plasma biomarkers (B) for predicting long-term risk of ACS patients. METHODS: We included 2729 ACS patients from the OCEA (Observation of cardiovascular events in ACS patients). The earlier admitted 1910 patients were enrolled as development cohort; and the subsequently admitted 819 subjects were treated as validation cohort. We investigated 10-year risk of cardiovascular (CV) death, myocardial infarction (MI) and all cause death in these patients. Potential variables contributing to risk of clinical events were assessed using Cox regression models and a score was derived using main part of these variables. RESULTS: During 16,110 person-years of follow-up, there were 238 CV death/MI in the development cohort. The 7 most important predictors including in the final model were NT-proBNP, D-dimer, GDF-15, peripheral artery disease (PAD), Fibrinogen, ST-segment elevated MI (STEMI), left ventricular ejection fraction (LVEF), termed as CB-ACS score. C-index of the score for predication of cardiovascular events was 0.79 (95% CI: 0.76-0.82) in development cohort and 0.77 (95% CI: 0.76-0.78) in the validation cohort (5832 person-years of follow-up), which outperformed GRACE 2.0 and ABC-ACS risk score. The CB-ACS score was also well calibrated in development and validation cohort (Greenwood-Nam-D'Agostino: P = 0.70 and P = 0.07, respectively). CONCLUSIONS CB-ACS risk score provides a useful tool for long-term prediction of CV events in patients with ACS. This model outperforms GRACE 2.0 and ABC-ACS ischemic risk score.

Hepatocellular adenoma(HCA)is a benign liver tumor with a low incidence.It mostly occurs in women of childbearing age,and often manifests as a single mass.This paper reported a case of multiple HCA in a middle-aged man.Serological examination showed elevated triglycerides level,and normal hepatic function.The patient had no history of viral hepatitis.Upper abdominal enhanced MRI examination showed multiple space-occupying lesions in liver,which tended to be benign.A total of 3 intrahepatic tumors were resected,and all of them were confirmed to be HCA by pathological examination.Both oncocytes and normal hepatocytes were found mild steatosis.The patient recovered well without tumor recurrence after surgery.

Objective:To design a virtual simulation tutorial system for bone traction nursing of the lower limbs, and to investigate its application effect.Methods:Based on clinical cases, a 3D model was established for the fractured lower limb using the virtual simulation technique. The design of the model considered the position and mechanical relationship between bone traction and fracture ends, as well as the assessment and intervention of the condition after bone traction, and such factors were taken as the core elements of simulation design. Virtual experiments were conducted for the four scenarios of pre-hospital first aid, triage in the hospital, bone traction operation, and postoperative nursing. Such experiments were conducted among junior nursing undergraduates, and examination results and student satisfaction survey were used to evaluate the application effect of the experiments.Results:The teaching software consisted of four training modules, i.e., theoretical knowledge learning of fractures, preparation before bone traction operation, methods and principles of bone traction operation, and observation of conditions after bone traction. The final score of experiments was (90.99±0.58) points among the students, and the degree of satisfaction with the experimental system and the teaching model was 87.85% (441/502) and 63.35% (318/502), respectively.Conclusions:The virtual simulation experiments for bone traction nursing of the lower limbs are scientific, professional, and interesting and have a relatively high degree of satisfaction among students, and therefore, they can be applied in the education of nursing students and the continuing education of nurses.

OBJECTIVE: To investigate the safety and efficacy of reinforced radiculoplasty in the treatment of symptomatic sacral Tarlov cysts (TCs). METHODS: A retrospective analysis was performed on the clinical data and follow-up data of 71 patients with symptomatic sacral TCs who underwent reinforced radiculoplasty in the Neurosurgery Department of Peking University Third Hospital from June 2018 to March 2021. All the operations were performed under neuroelectrophysiological monitoring. Intraoperative cyst exploration, partial resection of the cyst wall, narrowing of the leak, nerve root sleeve radiculoplasty and artificial dural reinforcement were performed. The incidence of postoperative complications and new neurological dysfunction was analyzed. Visual analogue scale (VAS) was used to assess the changes of pain before and after surgery. The Japanese Orthopedics Association (JOA) low back pain score was used to evaluate the changes in nerve function before and after surgery. RESULTS: In the study, 71 patients had 101 TCs, 19 (18.8%) TCs originated from the left S1 nerve, 26 (25.7%) originated from the left S2 nerve, 3 (3.0%) originated from the left S3 nerve, 14 (13.9%) originated from the right S1 nerve, 33 (32.7%) originated from the right S2 nerve, 6 (5.9%) originated from the right S3 nerve, all the TCs underwent reinforced radiculoplasty. Deep infection (1 case), subcutaneous effusion (1 case), fat li-quefaction (1 case) and urinary tract infection (4 cases) were recorded postoperatively. The patients were followed up for 12-43 months (median, 26 months). Two cases had new urinary retention after operation, and the catheter was removed at the end of the first and second months respectively. One case had new fecal weakness, which improved after 3 months. Compared with preoperation, VAS decreased significantly at the last follow-up [median, 6 (4-9) vs. 1 (0-5), Z=-7.272, P < 0.001], JOA score increased significantly [median, 20 (16-25) vs. 27 (18-29), Z=-7.265, P < 0.001]. There were 18 cured cases (25.4%), 41 excellent cases (57.7%), 8 effective cases (11.3%), and 4 invalid cases (5.6%). The total efficiency was 94.4% (67/71). Two (1.98%) cysts recurred. CONCLUSION For patients with symptomatic sacral TCs, reinforced radiculoplasty can significantly improve the pain and nerve function, which is safe and reliable.

AIM:To explore the influence factors of the treatment zone diameter(TZD)and its correlation with axial length growth(ALG)after Paragon CRT orthokeratology.METHODS: Retrospective clinical study. The data of 226 myopic patients(226 eyes)wearing Paragon CRT orthokeratology from April 2020 to September 2022 were collect. The correlated factors of TZD after wearing lens for 1mo, and the relationship between the overlapping treatment zone/ pupil area ratio and the ALG after wearing lens for 1a were analyzed.RESULTS: After wearing lens for 1mo, the TZD was negatively correlated with central corneal thickness(CCT)and positively correlated with the flat corneal eccentricity. After wearing lens for 1a, the ALG of the small TZD group(0.25±0.18mm)was significantly smaller than that of the large TZD group(0.34±0.24mm, P=0.002), and the ALG of the small area ratio group(0.24±0.19mm)was significantly smaller than that of the large area ratio group(0.35±0.23mm,P<0.001). Age and overlapping treatment zone area/pupil area ratio were significantly associated with the ALG in multivariate linear regression(all P<0.05).CONCLUSION: The wearers with thicker CCT and smaller flat corneal eccentricity usually had smaller TZD, and both the TZD and the overlapping treatment zone area/pupil area ratio were correlated with the ALG.

ObjectiveTo investigate the effect of chorionicity， gestational age at birth and birth weight discordance on neonatal outcomes in twin pregnancies. MethodsWe conducted a population-based retrospective study of monochorionic diamniotic （MCDA） twin pregnancies and dichorionic diamniotic （DCDA） twin pregnancies who were admitted in the First Affiliated Hospital， Sun Yat-sen University from January 2015 to December 2020. A total of 1504 live-born twins were included， with 386 cases in MCDA group and 1118 cases in DCDA groups， respectively. The comparison of neonatal outcomes between MCDA and DCDA twins was performed using t-test， Wilcoxon rank sum test， Chi-square test or Fisher’s exact test. Logistic regression was performed to evaluate the effects of chorionicity， gestational age at birth， birth weight discordance and sex on neonatal outcomes. There were 168 live-born twins affected by inter-twin birth weight discordance≥25%， with 96 cases in MCDA group and 72 cases in DCDA groups， respectively. Logistic regression was performed to evaluate the effects of chorionicity， gestational age at birth， birth weight light or heavy （small twin or large twin） of the twin and sex on neonatal outcomes. ResultsAmong the 1 504 newborns， gestational age at birth was lower in MCDA group compared with DCDA group （P = 0.000）， and the degree of birth weight discordance was higher in MCDA group than that of the DCDA group （P = 0.001）. Birth asphyxia， respiratory distress syndrome （RDS）， bronchopulmonary dysplasia （BPD）， and sepsis were more frequency in MCDA group compared with DCDA group （P = 0.000， P = 0.000， P = 0.000， P = 0.000）. Low gestational age at birth was an independent risk factor for birth asphyxia， RDS， BPD， sepsis， necrotizing enterocolitis （NEC）≥stageⅡ， acute kidney injury （AKI）， retinopathy of prematurity （ROP）， and neonatal death respectively （P = 0.000， P = 0.000， P = 0.000， P = 0.000， P = 0.011， P = 0.000， P = 0.000， P = 0.000）. High degree of birth weight discordance was an independent risk factor for birth asphyxia， RDS， BPD， sepsis and ROP respectively （P = 0.045， P = 0.000， P = 0.000， P = 0.004， P = 0.017 ）. Chorionicity was not an independent risk factor for neonatal morbidity and death （P > 0.05）. Among the 168 twins with birth weight discordance ≥25%， low gestational age at birth was an independent risk factor for birth asphyxia， RDS， BPD， sepsis and ROP， respectively （P = 0.000， P = 0.000， P = 0.000， P = 0.000， P = 0.000）； small twin was an independent risk factor for birth asphyxia and BPD， respectively （ P = 0.013， P = 0.001）； chorionicity was not an independent risk factor for neonatal morbidity （P > 0.05）. ConclusionChorionicity was not an independent risk factor for adverse neonatal outcome in twin births. Low gestational age at birth and high degree of birth weight discordance were independent risk factor for adverse neonatal outcome in twin births. Small twins had increased risk of adverse neonatal outcome in twins with birth weight discordance ≥25%.

From the perspective of academic history, the paper reviews systematically the background and evolution of the understanding of "Fengshi (GB 31) for treating wind disorders". In the ancient literature, there are no direct relevant statement for the indication of Fengshi (GB 31) associated with "wind", and the consensus on "Fengshi for treating wind disorders" has not been made yet. Under the influence of acupoint theory in recent era and the syndrome differentiation for acupuncture treatment in modern time, this statement becomes a conventional understanding and acceptable gradually. Meanwhile, the understanding for Fengshi (GB 31) treating wind disorders tends to be generalized. Practically, Fengshi (GB 31) is applicable for the various disorders in the local and adjacent areas. It is necessary for modern acupuncture researchers to systematically collate, investigate and identify the knowledge content with a sense of familiarity so that the contemporary inheritance, development and application of traditional theoretical knowledge of acupuncture can be enhanced.
