With the emergence of unhealthy dietary structures in people’s life， metabolic associated fatty liver disease （MAFLD） has gradually become the most important chronic liver disease in China， and there is also a gradual increase in the cases of MAFLD-associated liver cancer. Adipose tissue not only has the function of energy storage， but also secretes adipokines that play an important role in the development and progression of MAFLD and its associated liver cancer. Studies on the mechanism of adipokines have provided important help for the prevention and treatment of MAFLD， and a large number of studies have shown that the abnormal secretion of adipokines is associated with MAFLD and plays an important regulatory role in the development and progression of liver cancer. Adipokines are not only regulated at the gene level， but they can also interact with genes through specific pathways to co-regulate pathophysiological processes such as inflammation， metabolism， immunity， and cell proliferation in MAFLD and its associated liver cancer. This article reviews the latest studies on the association of adipokines with MAFLD and its associated liver cancer， in order to provide new directions for further research on the pathogenesis of liver cancer.

OBJECTIVE To explore the effects of isorhamnetin on the development of gastric cancer through up-regulation of solute carrier family 25 member 25 antisense RNA 1（SLC25A25-AS1）. METHODS Using BALB/c nude mice as the subjects， the xenograft tumor model was established by subcutaneously inoculating human gastric cancer MKN28 cells into the axillary region. The effects of low and high doses of isorhamnetin （20 and 40 mg/kg） on the tumor volume and mass in nude mice were investigated. MKN28 cells were selected and divided into control group， isorhamnetin group （70 μmol/L， similarly hereinafter）， isorhamnetin+knocking down negative control group， isorhamnetin+knocking down SLC25A25-AS1 group， isorhamnetin+ overexpression negative control group and isorhamnetin+overexpressing SLC25A25-AS1 group. Effects of knocking down/ overexpressing SLC25A25-AS1 on viability， apoptosis， migration and invasion ability of isorhamnetin-treated cells were detected. After verifying the targeting relationships between microRNA-212-3p （miR-212-3p） and SLC25A25-AS1， as well as phosphatase and tensin homologue deleted on chromosome 10 （PTEN）， the effects of knocking down/overexpressing SLC25A25-AS1 on the expression of miR-212-3p， PTEN mRNA， and PTEN protein in isorhamnetin-treated cells were investigated. RESULTS Compared with the model control group， tumor volume and mass of nude mice in the isorhamnetin low-dose and high-dose groups were reduced significantly， and the isorhamnetin high-dose group was significantly lower than the isorhamnetin low-dose group （P＜0.05）. miR-212-3p had targeting relationships with SLC25A25-AS1 and PTEN. Compared with the control group， the cell viability （intervened for 24， 48 h）， migration number， invasion number and miR-212-3p expression of cells in the isorhamnetin group， isorhamnetin+knocking down negative control group and isorhamnetin+overexpressing negative control group were significantly reduced or decreased or down-regulated， while the apoptosis rate， mRNA and protein expressions of PTEN were significantly increased or up-regulated （P＜0.05）. Compared with isorhamnetin group and isorhamnetin+knocking down negative control group， the cell viability， migration number， invasion number and miR-212-3p expression of cells in the isorhamnetin+knocking down SLC25A25-AS1 group were significantly increased or up- regulated， while the apoptosis rate， mRNA and protein expressions of PTEN were significantly reduced or down-regulated （P＜ 0.05）. Compared with isorhamnetin group and isorhamnetin+overexpressing negative control group， the cell viability， migration number， invasion number and miR-212-3p expression of cells in isorhamnetin+overexpressing SLC25A25-AS1 group were significantly reduced or decreased or down-regulated， while the apoptosis rate， PTEN mRNA and protein expressions were significantly increased or up-regulated （P＜0.05）. CONCLUSIONS Isorhamnetin may inhibit the development of gastric cancer by up-regulating the expression of SLC25A25-AS1， down-regulating miR-212-3p， and up-regulating the expression of PTEN， which is a downstream target of miR-212-3p.

Objective To analyze the clinical features of chronic obstructive pulmonary disease (COPD) patients with heart failure (HF) in Nanjing and explore the influencing factors. Methods A total of 773 COPD inpatients were selected from January 2021 to January 2024 in Nanjing Combined Hospital of Traditional Chinese and Western Medicine, Nanjing Qixia District Hospital, Nanjing Lishui District People's Hospital, Nanjing Pukou District Hospital of Traditional Chinese Medicine and Nanjing First Hospital., and were divided into 2 groups according to the presence or absence of combined HF. The general data and medical records of the two groups were compared, the clinical characteristics of COPD patients with HF were summarized, and the influencing factors of COPD patients with HF were analyzed by multivariate logistic regression. Results Among the 242 patients (31.31%) with COPD had HF, chronic paroxysmal dyspnea was the most common first symptom, 169 patients (69.83%) had left heart failure, 63 patients (30.17%) were diagnosed as right heart failure or global heart failure , 17 patients (7.02%) had myocardial infarction. Multivariate logistic regression analysis showed that the risk of HF was 1.678 times and 1.691times higher in COPD groups ≥ 50 years old and male COPD groups than in < 50 years old and female groups, respectively; the risk of HF was 1.491 times higher in COPD groups engaged in physical work than in physical work groups; the risk of HF was 1.447 times and 1.580 times higher in COPD groups with hypertension and coronary heart disease than in COPD groups without hypertension and coronary heart disease, respectively; the risk of HF was 1.859 times higher in COPD groups smoking>400 vial/year than in COPD groups≤400 vial/ year; the risk of HF was 1.757 times higher in COPD groups with acute exacerbation frequency≥2 times/year than in COPD groups<2 times/year; the above differences were statistically significant (P<0.05). Conclusion Attention should be paid to elderly, male and heavy physical work group of COPD patients. Active treatment of hypertension and coronary heart disease, effective tobacco control and reduction of the frequency of acute exacerbation are effective ways to reduce the risk of HF in COPD patients in Nanjing.

Aortic dissection is a life-threatening cardiovascular disease with devastating complications and high mortality. It requires rapid and accurate diagnosis and a focus on prognosis. Many laboratory tests are routinely performed in patients with aortic dissection including D-dimer, brain natriuretic peptide, cardiac troponin I, C-reactive protein, and procalcitonin. D-dimer shows vital performance in the diagnosis of aortic dissection, and brain natriuretic peptide, cardiac troponin I, C-reactive protein, and procalcitonin exhibits important value in risk stratification and prognostic effect in aortic dissection patients. Our review summarized the clinical utility of these laboratory tests in patients with aortic dissection, aiming to provide advanced and comprehensive evidence for clinicians to better understand these laboratory tests and help their clinical practice.

Objective: To explore the relationship of physical activity (PA) and sedentary behavior (SB) with cardiorespiratory fitness (CRF) among middle schoold students in Tibet, so as to provide empirical references for improving the cardiorespiratory fitness and health levels of adolescents in Tibet. Methods: From August to December 2020, 1 225 junior and senior high school students were selected from 2 middle schools in Lhasa, Tibet Autonomous Region, using the stratified cluster random sampling method. Triaxial accelerometers were used to evaluate PA and SB behaviors, and the 20 meter shuttle run was employed to assess CRF among the middle school students. Isochronous substitution modeling was used to analyze the associations of SB, low intensity physical activity (LPA), and moderate vigorous physical activity (MVPA) with CRF, and the saturation threshold effect in the dose response relationship between MVPA and CRF was analyzed through restricted cubic spline and two stage linear regression. Results: After adjusting for covariates such as gender, body mass index and sleep quality score, isotemporal substitution analysis showed that among junior high school students aged 13-15, replacing 30 minutes of SB ( B =1.73) or LPA ( B =2.38) with MVPA were positively associated with CRF (both P <0.05). Among senior high school students aged 16-18, replacing SB ( B =0.99) or LPA ( B =1.38) with MVPA were also positively associated with CRF (both P <0.05). Restricted cubic spline and two piecewise linear regression analyses indicated that only middle school girls aged 13-18 exhibited a saturation threshold effect between MVPA and CRF (logarithmic likelihood ratio test=0.03), with the optimal CRF improvement observed at 60 minutes of MVPA per day ( B=0.13, P ＜ 0.01). Conclusions Reducing SB and LPA while increasing MVPA can improve CRF in Tibetan middle school students. To maximize CRF improvement, middle school girls should engage in at least 60 minutes of MVPA daily.

Objective　The objective of this research is to construct a technical indicator framework for preventing the of re-establishment of imported malaria at the county level in China, excluding border areas, with the aim of guiding specialist agencies to prevent the re-establishment of imported malaria in a scientific, feasible and comprehensive way. Methods　The preliminary framework was built based on literature review and on-site research. Two rounds of Delphi consultation were carried out. The positive coefficient, degree of concentration, degree of coordination, and authority of the experts were calculated. The weights and the combined weights for the indicators were determined using the analytic hierarchy process and probability method, respectively. Results　Twenty experts were invited in the 1st round of consultation, and twenty-six in the 2nd round. The authority coefficients of the experts for two rounds were 0.955 and 0.968, respectively. The P value of the degree of coordination of two rounds were less than 0.05. The final framework included 5 primary indicators, 19 secondary indicators and 42 tertiary indicators. Primary indicators included government-led, joint control and prevention, surveillance and response, capacity building and organization guarantee, whose weights were 20.2%, 2.4%, 20.1%, 44.7% and 12.5%, respectively. Among the secondary indicators, the highest combined weight was medical institutions (25.0%) of capacity building, and the lowest was cross-sectoral cooperation (0.3%) of joint control and prevention. The three tertiary indicators with higher combined weights were: "1.2.1 There is a comprehensive plan for preventing the re-establishment of imported malaria, and the responsibilities of relevant departments are clearly defined" accounting for 14.9%; "4.1.4 Laboratory personnel in medical institutions possess the ability to conduct microscopic examinations for malaria detection" accounting for 10.6%; and "4.2.1 Specialized malaria surveillance laboratories have been established and are fully equipped with the necessary capabilities to conduct effective surveillance" accounting for 7.6%.

The framework provides an operational, scientific and comprehensive technical guidance for county-level areas from the perspective of the effectiveness of government-led, joint prevention and control, surveillance and response, capacity building and organizational support. The importance of maintaining the capacity to prevent re-establishment of imported malaria and whole-process case management under medical and preventive cooperation in the post-elimination stage was highlighted.

BACKGROUND: Oral squamous cell carcinoma (OSCC) is a prevalent type of cancer with a high mortality rate in its late stages. One of the major challenges in OSCC treatment is the resistance to epidermal growth factor receptor (EGFR) inhibitors. Therefore, it is imperative to elucidate the mechanism underlying drug resistance and develop appropriate precision therapy strategies to enhance clinical efficacy. METHODS: To evaluate the efficacy of the combination of the Ca 2+ /calmodulin-dependent protein kinase II (CAMK2) inhibitor KN93 and EGFR inhibitors, we performed in vitro and in vivo experiments using two FAT atypical cadherin 1 ( FAT1 )-deficient (SCC9 and SCC25) and two FAT1 wild-type (SCC47 and HN12) OSCC cell lines. We assessed the effects of EGFR inhibitors (afatinib or cetuximab), KN93, or their combination on the malignant phenotype of OSCC in vivo and in vitro . The alterations in protein expression levels of members of the EGFR signaling pathway and SRY-box transcription factor 2 (SOX2) were analyzed. Changes in the yes-associated protein 1 (YAP1) protein were characterized. Moreover, we analyzed mitochondrial dysfunction. Besides, the effects of combination therapy on mitochondrial dynamics were also evaluated. RESULTS: OSCC with FAT1 mutations exhibited resistance to EGFR inhibitors treatment. The combination of KN93 and EGFR inhibitors significantly inhibited the proliferation, survival, and migration of FAT1 -mutated OSCC cells and suppressed tumor growth in vivo . Mechanistically, combination therapy enhanced the therapeutic sensitivity of FAT1 -mutated OSCC cells to EGFR inhibitors by modulating the EGFR pathway and downregulated tumor stemness-related proteins. Furthermore, combination therapy induced reactive oxygen species (ROS)-mediated mitochondrial dysfunction and disrupted mitochondrial dynamics, ultimately resulting in tumor suppression. CONCLUSION Combination therapy with EGFR inhibitors and KN93 could be a novel precision therapeutic strategy and a potential clinical solution for EGFR-resistant OSCC patients with FAT1 mutations.

OBJECTIVE: To explore the reliability and accuracy of the arbitrary point method for measuring the anteversion angle of acetabular prosthesis after total hip arthroplasty (THA) based on pelvic X-ray films. METHODS: The clinical data of 23 patients (25 hips) who underwent THA between December 2018 and September 2023 and met the selection criteria were retrospectively analyzed. Among them, there were 16 males and 7 females, with an average age of 57.6 years (range, 34-81 years); 13 hips had THA on the left side and 12 on the right side. There were 19 cases (21 hips) of osteonecrosis of the femoral head, 2 cases (2 hips) of femoral neck fractures, 1 case (1 hip) of developmental dysplasia of the hip, and 1 case (1 hip) of osteoarthritis. After THA, all patients underwent X-ray examination and CT scan. Three physicians measured the anteversion angle of acetabular prosthesis using the arbitrary point method and the CT measurement method respectively, and repeated the measurements three times. The results of the two measurement methods were compared, and the intraclass correlation coefficient (ICC) was employed to assess the reproducibility of the methods. RESULTS: The anteversion angles of acetabular prosthesis were (15.87±7.73)° measured by the arbitrary point method, and (15.31±7.89)° measured by CT measurement method. There was no significant difference between the two methods ( t=1.515, P=0.143). The ICC of the measurement results by the arbitrary point method for the three physicians were 0.97 ( P<0.001), 0.96 ( P<0.001), and 0.96 ( P<0.001), respectively; and the ICC of the measurement results by CT method were 0.93 ( P<0.001), 0.93 ( P<0.001), and 0.94 ( P<0.001), respectively. CONCLUSION The arbitrary point method for measuring the anteversion angle of acetabular prosthesis after THA based on pelvic X-ray film is easy to operate, accurate, and has high reproducibility.

Lung cancer, particularly non-small cell lung cancer (NSCLC), is a leading cause of cancer-related mortality worldwide. In recent years, metabolomics has emerged as a key systems biology approach for analyzing small-molecule metabolites in cells, tissues and organisms. It provides new strategies for early diagnosis and metabolic profiling. Additionally, metabolomics plays a crucial role in studying resistance mechanisms in lung cancer. Tumor cell metabolic reprogramming is a key driving factor in the initiation and progression of lung cancer. Metabolomics studies have revealed how lung cancer cells regulate critical pathways such as energy metabolism, lipid metabolism, and amino acid metabolism to adapt to the demands of rapid proliferation and invasive metastasis. This review summarizes the latest advances in metabolomics research in lung cancer, focusing on the characteristics of metabolic reprogramming, the identification of potential metabolic biomarkers, and the prospects of metabolomics in early diagnosis and the elucidation of resistance mechanisms in lung cancer.

OBJECTIVE: To identify the risk factors associated with the development of post-Nuss procedure scoliosis in pectus excavatum patients and to establish a relevant predictive model. METHODS: A retro-spective review was conducted on pectus excavatum patients who underwent Nuss procedure in Department of Thoracic Surgery at Beijing Jishuitan Hospital between January 2018 and February 2023. We gathered the patient demographic information (including age, sex, height, weight, and body mass index) and diagnostic imaging results (echocardiogram, chest CT scan, full-spine radiography, and PA/lateral chest X-rays), and measurements of Haller index, asymmetry index, sternal torsion angle (STA) index, and Cobb angle changes. The risk of post-Nuss procedure scoliosis was assessed. Cox regression analysis was performed to identify independent risk factors for scoliosis development in the pectus excavatum patients. Based on the results of the Cox regression analysis, a risk prediction model was established, and its specific predictive performance was assessed through internal cross-validation. RESULTS: A total of 59 pectus excavatum patients who underwent Nuss procedure were included after applying inclusion and exclusion criteria. The median follow-up duration was 6.84 months, and the follow-up results showed significant improvements in Haller index, STA index, and asymmetry index postoperatively. Twelve patients developed scoliosis 3 months after Nuss procedure, while 47 patients did not, the incidence of scoliosis was 20.3%. Cox regression analysis identified preoperative pulmonary artery hypertension and preoperative asymmetry index as independent risk factors for post-Nuss procedure scoliosis. A predictive model was constructed based on single-factor Cox regression analysis results, incorporating age, height, weight, body mass index, preoperative pulmonary artery hypertension, preoperative Haller index, STA index, asymmetry index, and Cobb angle. The receiver operating characteristic (ROC) curve was plotted, and the area under the curve (AUC) for the overall predictive model was calculated to be 0.995. A calibration curve demonstrated good alignment between predicted values and actual values. CONCLUSION Nuss procedure achieved favorable clinical outcomes. However, postoperative scoliosis emerged as a significant complication with a high incidence rate. Pulmonary artery hypertension and asymmetry index were independent predictors of post-Nuss procedure scoliosis. The predictive model developed in this study demonstrated robust performance in estimating the risk of postoperative scoliosis.
