Epigenomic imbalance drives abnormal transcriptional processes,promoting the onset and progression of cancer.Although defective gene regulation generally affects carcinogenesis and tumor suppression networks,tumor immunogenicity and immune cells involved in antitumor responses may also be affected by epigenomic changes,which may have significant implications for the development and application of epigenetic therapy,cancer immunotherapy,and their combinations.Herein,we focus on the impact of epigenetic regulation on tumor immune cell function and the role of key abnormal epigenetic processes,DNA methylation,histone post-translational modification,and chromatin structure in tumor immunogenicity,and introduce these epigenetic research methods.We emphasize the value of small-molecule inhibitors of epigenetic modulators in enhancing antitumor immune responses and discuss the challenges of developing treatment plans that combine epigenetic therapy and immuno-therapy through the complex interaction between cancer epigenetics and cancer immunology.

Objective:This study aimed to explore the clinical value of myostatin(MST) and follistatin(FST) as biological biomarkers in evaluating sarcopenia in elderly women.Methods:This was a retrospective cross-sectional study that enrolled 350 females aged 20-89 years who underwent physical examinations in Shanghai Huadong Hospital in 2021. Demographic characteristics, muscle mass, fat mass, bone mineral density, hand grip strength, gait speed, and serum indices of MST and FST were collected.Results:The serum levels of MST did not change significantly with age. However, the serum levels of FST increased with age. In women aged≥60 years, MST was positively correlated with total lean mass and appendicular skeletal muscle index(ASMI; r=0.236, P=0.041; r=0.289, P=0.014), while FST was negatively correlated with ASMI( r=-0.265, P=0.030). In multivariate stepwise regression analysis, after adjusting for age, body mass index, hip bone mineral density, and total fat mass, only FST was independently correlated with ASMI( β=-0.238, P=0.006), while MST was not correlated with ASMI. The receiver operating characteristic curve was plotted using muscle mass reduction as the state variable and serum FST level as the test variable. The area under the curve was 0.753. And when the FST cutoff value was 17.49 ng/mL, the maximum Jordan index was 0.46, with a sensitivity of 77.3% and a specificity of 68.7%. Women aged ≥60 years were divided into three groups based on serum FST levels. Compared to the upper third of the serum FST level group, the low third of the FST level group had a significantly reduced risk of suffering from sarcopenia( OR=0.098, P =0.036). Conclusions:Serum FST lever has a better correlation with muscle mass among elderly women, making it a promising biomarker for evaluating muscle mass.

Objective:To investigate the intention to stay on among primary health care workers (PHWs) during the COVID-19 epidemics and its influencing factors.Methods:An online questionnaire survey was conducted among PHWs from 62 primary health institutions in 31 provinces, autonomous regions and municipalities across China selected by multi-stage whole cluster random sampling method between May and October 2022. According to the job position, the PHWs were divided into 5 categories: general practitioners (GPs), nurses, public health doctors, managers and support staff. Intention to stay was measured using the Chinese version of the Intention to Stay Questionnaire. Multiple linear regression model was used to analyze the influencing factors of the intention to stay in PHWs of different occupational categories, including personal factors, work factors, factors related to the COVID-19 and psychological reactions.Results:A total of 3 769 PHWs from 44 community health service centers, 18 township hospitals of 27 provinces/autonomous regions and 4 municipalities participated in this survey. The mean age of participants was (37.4±9.2) years, including 2 971(78.8%) women. The mean score of intention to stay of participants was 21.7±4.1. Compared with GPs, managers had lower intention to stay ( P=0.004). Age, female, in marriage, monthly income, years of primary care service, self-evaluation of unit support function, MSQ-SF score, and PA score were positively correlated with the score of intention to stay (all P<0.05), while PHQ-9 score, EE score, and DP score were negatively correlated with the score of intention to stay (all P<0.05). The MSQ-SF scores of all occupational categories were positively correlated with the scores of intention to stay (all P<0.01). In addition, among GPs, monthly income, years of service in primary care, self-evaluation of unit support function, and PA scores were positively correlated with the score of intention to stay (all P<0.05), while PHQ-9 scores and EE scores were negatively correlated with the score of intention to stay (all P<0.05). Among nurses, age, female gender, monthly income, self-evaluation of unit support function, and PA score were positively correlated with the score of intention to stay (all P<0.05), while EE scores and retention will score were negatively associated with ( P<0.001). Among public health doctors, in marriage was positively correlated with the score of intention to stay ( P=0.018). Among managers, DP score was negatively correlated with the score of intention to stay ( P=0.001). Among support staff, female gender, monthly income, years of primary care service, self-evaluation of unit support function, and PA scores were positively correlated with the score of intention to stay (all P<0.05), while EE score and DP score were negatively correlated with intention to stay (all P<0.05). Conclusions:The intention to stay of PHWs in China during the COVID-19 was at an intermediate level, which was affected by many factors. Among them, job satisfaction was positively correlated with the intention to stay of all occupational categories, and the influencing factors of different occupational categories have some variations.

Objective:To investigate the clinical significances of evaluation indexes of right heart function injury in patients with BCR-ABL-negative myroproliferative neoplasms (MPN).Methods:The clinical data of 208 patients with BCR-ABL-negative MPN diagnosed in the Second People's Hospital of Lianyungang and Jiangsu Province Hospital from January 2015 to August 2021 were retrospectively analyzed, including 63 cases of primary myelopathic fibrosis (PMF), 39 cases of polycytosis vera (PV) and 106 cases of essential thrombocythemia (ET). The clinical characteristics of patients and the examination results of hematological related indicators were compared among the three groups. The examination results of indexes of right heart function injury were analyzed, including echocardiography, brain natriuretic peptide, soluble growth stimulation expression gene-2 (sST-2), lactate dehydrogenase (LDH), D-dimer, ferritin, β 2-microglobulin, peripheral blood WT1 gene, CD34 + cell count, etc. Results:Of the 208 patients, 109 were male and 99 were female; the median age was 62 years old (23 years old, 89 years old). The differences in levels of hemoglobin, platelet count, D-dimer, LDH and ferritin among PMF, PV and ET patients were statistically significant (all P < 0.05). Color echocardiography was performed in 87 patients, including 26 cases of PMF, 19 cases of PV and 42 cases of ET. Pulmonary artery pressure increased in 69 cases (79.3%), left atrial diameter increased in 76 cases (87.3%), and diameter increased during right ventricular diastolic period in 59 cases (67.8%). There were significant differences in pulmonary artery pressure, left atrial diameter and diameter during right ventricular diastolic period among PMF, PV and ET patients (all P < 0.05). Pearson correlation analysis showed that pulmonary artery pressure was positively correlated with ferritin, LDH, sST-2 and age ( r values were 0.796, 0.768, 0.915 and 0.734, all P<0.05), while it was negatively correlated with platelet count ( r = -2.330, P = 0.034). Conclusions:For BCR-ABL-negative MPN patients, the increase of pulmonary artery pressure, ferritin and LDH and the decreased platelet count and hemoglobin may increase the probability of right heart function impairment. For BCR-ABL-negative MPN patients with the higher levels of ferritin, LDH, sST-2, age, and the lower level of platelet count, the pulmonary artery pressure may be higher.
