Lung cancer is the fastest-growing cancer type in terms of incidence and mortality worldwide, posing a huge threat to the health and life of the population. Radiation therapy is one of the main methods for treating lung cancer, and there is a clear dose-effect relationship between the radiation dose and local control rate of lung cancer. However, the lung is a radiation dose-limiting organ, and the radiation resistance of lung cancer tissues and the radiation damage to normal tissues limit the radiation efficacy for lung cancer. The pathogenesis of lung cancer in traditional Chinese medicine (TCM) is characterized by an initial deficiency in vital Qi, followed by the internal invasion and gradual accumulation of pathogenic Qi. After radiation therapy for lung cancer, the body's vital Qi becomes weaker, and syndromes of phlegm coagulation, Qi stagnation, and static blood blocking collaterals become more severe, leading to radiation resistance of lung cancer tissues. Therefore, the key issue to better clinical efficacy of radiation therapy for lung cancer patients is to use drugs to enhance the radiation sensitivity of lung cancer cells and improve the radiation tolerance of normal lung tissues. TCM can be used as a radiation sensitizer by regulating the cell cycle to increase the proportion of cells in the radiation-sensitive phase, promoting upregulation of pro-apoptotic genes and downregulation of anti-apoptotic genes to induce cell apoptosis, enhancing DNA damage caused by radiation and inhibiting damage repair, improving blood circulation and tissue oxygen supply, and so on, to enhance the sensitivity of tumor cells to radiation and amplify the toxicity of radiation to tumor tissues. TCM can also be used as a radiation protector by inhibiting cell damage, regulating cytokines and immune balance, reducing the release of inflammatory and fibrotic factors, and inhibiting the activation of related signaling pathways to prevent and treat radiation-induced lung injury. This article systematically reviewed the research results of TCM on radiation sensitization and radiation protection in lung cancer in recent years, aiming to elucidate the mechanism of TCM in regulating the effect of radiation therapy for lung cancer and provide more theoretical and practical basis for TCM to participate in improving the prognosis of lung cancer patients undergoing radiation therapy.

Objective To investigate the relationship between the composite dietary antioxidant index (CDAI) and excess heart age (EHA), offering theoretical insights into the nutritional prevention of cardiovascular disease (CVD). Methods Data for this cross-sectional analysis was derived from the National Health and Nutrition Examination Survey (NHANES) from 2007 to 2020, which included 16 442 participants aged 30 to 74 years without a history of CVD. The heart age was estimated using the Framingham risk score function, and EHA was subsequently calculated. The CDAI was formulated based on intake levels of vitamins A, C, E, zinc, selenium, and carotenoids to represent the overall level of antioxidants. The association between CDAI and EHA was evaluated using multivariate linear regression, multivariate logistic regression, and restricted cubic splines (RCS). Results Multiple regression analysis indicated that CDAI was negatively correlated with both EHA (β=-0.07, 95%CI: -0.14 to -0.01) and high CVD risk (defined as EHA≥10 years) (OR=0.98, 95%CI: 0.96 to 1.00), with RCS analysis suggesting that this relationship is a nonlinear and inverse L-shaped. In the female subgroup, significant negative, nonlinear associations were observed between CDAI and both EHA (β=-0.10, 95%CI: -0.12 to 0.00) and high CVD risk (OR=0.97, 95%CI: 0.94 to 0.99). Conversely, in males, these correlations did not reach statistical significance. Conclusions Our findings suggest that individuals with higher CDAI compliance had a lower risk of CVD, and this negative correlation was gender specific. This discovery offers new theoretical guidance for the nutritional prevention of CVD, underlining the necessity for more comprehensive clinical and foundational research to further explore this association.

Objectives:Interatrial block(IAB)is a conduction delay between the right and left atria,which is a phenomenon recognized as an electrocardiogram(ECG)feature of atrial fibrosis.This study aimed to investigate the relationship between advanced IAB and in-hospital new-onset atrial fibrillation(NOAF)in patients with ST-segment elevation myocardial infarction(STEMI). Methods:This single-center retrospective observational study consecutively enrolled 916 patients diagnosed with STEMI from September 2019 to June 2022,who underwent primary percutaneous coronary intervention within 24 hours of onset.ECG was recorded in all patients at the first medical contact,and the ECG was scanned and uploaded on the official China Chest Pain Center platform.The detection rate of IAB and the incidence of NOAF in STEMI patients were analyzed,and the possible associated factors of new-onset atrial fibrillation during hospitalization of STEMI patients were evaluated by logistic regression analysis. Results:IAB was detected in 269(29.4%)patients,57(21.2%)of these patients had advanced IAB.In-hospital NOAF was detected in 89(9.7%)patients.Multivariate analysis showed age(OR=1.070,95%CI:1.045-1.095,P<0.001),left ventricular ejection fraction(OR=0.929,95%CI:0.901-0.957,P<0.001),right coronary artery lesion(OR=1.672,95%CI:1.042-2.683,P=0.033),and advanced IAB(OR=4.007,95%CI:1.973-8.138,P<0.001)were independent determinants of in-hospital NOAF among STEMI patients.Integrated discrimination improvement(IDI)and net reclassification improvement(NRI)were improved significantly when advanced IAB was included in the NOAF risk model with a satisfactory C index(0.742). Conclusions:Advanced IAB is an independent risk marker for NOAF in patients with STEMI.Advanced IAB has incremental impact for improving the discriminatory accuracy of the NOAF predicting model.

Objective:To study the relationship between endoplasmic reticulum stress (ERS) and apoptotic protein and myocardial pathological changes in rats after endostar combined with low-dose X-ray irradiation.Methods:Forty SD rats were evenly divided into four groups: control group (intraperitoneal injection of equal volume physiological saline, once per day, 14 d), endostar group (intraperitoneal injection of endostar 6 mg/kg, once per day, 14 d), irradiation group (15 Gy divided into 3 times X-ray irradiation) and combination group (intraperitoneal injection of endostar after irradiation at the same dose and time as the endostar group). At 1 and 6 months after treatment, myocardial tissues of rats were prepared for HE staining and Masson staining to observe the myocardial histological changes. TUNEL assay was used to detect myocardial cell apoptosis, and ImageJ software was utilized to calculate myocardial collagen volume fraction (CVF). The expression levels of ERS and apoptotic protein glucose-regulated protein 78 (GRP78), protein kinase-like endoplasmic reticulum kinases (PERK), CCAAT/enhancer binding protein homologous protein (CHOP) and cysteine-containing aspartate-specific protease-12 (Caspase-12) were detected by Western blot. One-way ANOVA was conducted using GraphPad Prism 8.0.1 software, and comparison between two groups was conducted using t-test. Results:At 6 months after treatment, the myocardial interstitium in the irradiation and combination groups was widened, showing strip-like or reticular fibrosis changes, and the myocardial interstitium had diffuse collagen fiber deposition. Compared with the control group, CVF was increased significantly (both P<0.01). At 1 and 6 months after treatment, the apoptotic index of myocardial cells in the combination group was significantly higher than that in the control group ( P<0.05, <0.001). At 1 and 6 months after treatment, the expression levels of GRP78 protein in the irradiation and combination groups were increased (all P<0.01), and the expression levels of PERK and CHOP proteins in the combination group were increased compared to those in the control group (both P<0.05). At 6 months after treatment, the expression levels of PERK and CHOP proteins in the irradiation group were increased compared to those in the control group (both P<0.05). Compared with the control group, Caspase-12 expression levels at 1 and 6 months after treatment were increased in the endostar, irradiation and combination groups (all P<0.05). Conclusions:The expression levels of ERS and apoptotic proteins are related to cardiac injury caused by irradiation in rats. After low-dose X-ray combined with endostar treatment, ERS is aggravated and myocardial apoptosis is increased.
