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.

Based on the compound pathogenesis theory of malignant tumor,this article combines the theories of positive-evil,yin-yang,and central qi theories with the theory of cancer toxin,pointing out that the deficiency of positive and excess of evil are the basis for the onset of tumors.The pathogenesis characteristics of tumors are the loss of both yin and yang,stagnation of qi,and cancer toxin deeply lurking.The paper believes that the loss of both yin and yang often originates from the spleen and kidney,stagnation of qi is first blamed on the spleen and stomach,and cancer toxin deeply lurking often accompanies multiple evil qi.Based on this,the detoxi-cation method of warming and nourishing is proposed to treat malignant tumors.It is the combination or sequential application of the three methods of warming,nourishing,and detoxification,which play the role of warming and nourishing together,harmonizing yin and yang;promoting the circulation of qi,relieving depression,and regulating emotions;eliminating cancer and toxin,and breaking the combined evil.

Objective:To explore the clinical effect of laparoscopic anatomical hepatic segment Ⅷ (S8) resection.Methods:Of 16 patients with liver cancer who underwent laparoscopic anatomical hepatic S8 resection at the National Cancer Center from October 2020 to October 2022 were were enrolled, including 13 males and 3 females, aged (59.1±10.9) years. The operation time, intraoperative blood loss, occurrence of intraoperative blood transfusion, and postoperative complications were retrospectively analyzed. Recurrence and survival were followed up by outpatient and telephone reviews.Results:Laparoscopic anatomical hepatic S8 resection was successfully performed in 16 patients without conversion to laparotomy. Among them, 10 patients underwent the intraoperative ultrasound guided hepatic parenchymal approach, and 6 underwent laparoscopic Glissonean pedicle puncture for the positive staining of S8 using indocyanine green. The operation time was (274.8±82.8) min, and the intraoperative blood loss was [ M( Q1, Q3)] 100.0 (50.0, 200.0) ml. There were no intraoperative blood transfusion or postoperative complication. The drainage tube was successfully removed and the patients were discharged 5 to 7 days after surgery. The patients were followed up for 5 to 24 months and all survived. Two patients had tumor recurrence. Conclusion:Laparoscopic anatomical S8 resection is safe and feasible.

Objective:To analyze the clinical value of noninvasive pressure strain loop (PSL) in assessing left ventricular myocardial work in patients with essential hypertension.Methods:In this cross-sectional study, 66 patients with essential hypertension who were admitted to the Affiliated Hospital of Yangzhou University from August to December 2020 were continuously enrolled. According to left ventricular mass index (LVMI) >95 g/m 2 in women and >115 g/m 2 in men,≤95 g/m 2 in women and ≤115 g/m 2 in men, the 66 patients were divided into left ventricular hypertrophy (LVH) group (14 cases) and non-left ventricular hypertrophy (NLVH) group (52 cases). Furthermore, the NLVH group was divided into a mild group (30 cases) and a moderate/severe group (22 cases) according to the systolic blood pressure of 140~159 mmHg (1 mmHg=0.133 kPa) and ≥160 mmHg. Another 25 healthy adults who underwent physical examination during the same period were included as healthy control group. The height, weight and blood pressure were measured in all the subjects, and routine echocardiography and speckle tracking imaging analysis were performed. PSL results were obtained by combining the results of speckle tracking imaging analysis with systolic blood pressure. The differences of general clinical data, basic parameters of two-dimensional ultrasound and myocardial work parameters of PSL (global work index, global effective work, global wasted work, and global work efficiency) were compared among the groups, and the clinical value of PSL in assessing left ventricular myocardial work in patients with essential hypertension was analyzed. Results:There was no significant difference in left ventricular ejection fraction among all groups (all P>0.05). The global work index of moderate/severe NLVH group was significantly higher than that of mild NLVH group, LVH group and healthy control group [(2 630±231) vs (2 254±179), (1 847±261), (1 724±209) mmHg%]. The global effective work of moderate/severe NLVH group was significantly higher than that of LVH group and healthy control group [(2 965±261) vs (2 330±258) and (2 121±163) mmHg%] (all P<0.05). The global wasted work of LVH group was significantly higher than that of moderate/severe NLVH group, mild NLVH group and healthy control group [(248±107) vs (141±57), (116±57), (83±58) mmHg%] (all P<0.05). The global work efficiency was significantly lower than that of moderate/severe NLVH group, mild NLVH group and healthy control group (89.1%±3.9% vs 94.3%±1.9%, 95.0%±1.8%, 95.8%±2.3%) (all P<0.05). With the increase of blood pressure, the PSL decreased in the LVH group and increased in the other three groups. The bull′s eye diagram of myocardial work in the healthy control group was uniform green (normal effective work area), red began to appear in the mild NLVH group (high intensity myocardial work area), red area increased in the moderate/severe NLVH group, and blue appeared in the LVH group (ineffective work area). Conclusions:PSL has good clinical value in assessing left ventricular myocardial work in patients with primary hypertension. The parameters derived from PSL data can sensitively identify impaired systolic function in individuals with normal left ventricular ejection fraction.

Objective:To study the use of the Glissonean pedicle approach based on the triangular area among the right anterior pedicle, the right posterior pedicle and the right hepatic vein ( "APR triangle" ), followed by indocyanine green fluorescence negative staining in laparoscopic anatomical resection of right hepatic segments.Methods:The clinical data of 34 patients with liver tumors who underwent laparoscopic anatomical right hepatic segmentectomy at the Chinese Academy of Medical Sciences and Peking Union Medical College from September 2020 to September 2021 were analyzed retrospectively. Of the 34 patients, there were 24 males and 10 females, aged (58.3±10.3) years old. Data on completion of operation, operation time, intraoperative blood loss, intraoperative blood transfusion, postoperative complications and postoperative hospital stay were collected.Results:All the 34 patients had malignant liver tumors, and they were successfully operated using total laparoscopic surgery. There was no conversion to open surgery. Three patients underwent segment V resection, 3 patients segment VI resection, 5 patients segment VII resection, 2 patients segment V + segment VI resection, 9 patients segment VI + segment VII resection, 3 patients segment V + segment VII resection, 5 patients segment V dorsal segment + segment VI + segment VII resection, 3 patients right posterior section resection + anterior dorsal segment resection and 1 patient anterior dorsal section resection. The operation time was (275.58±82.28) min, the amount of intraoperative blood loss was 100(100, 300) ml, and there were no patients requiring blood transfusion during the operation. Liquid food was started on the first day after operation, and out-of bed activities were carried out on the second to third days after operation. The Clavien Dindo classification of postoperative complications was grade I in 32 patients and grade III in 2 patients. The postoperative hospital stay was (7.23±3.10) d. All tumor margins were negative for malignancy. All the 34 patients were followed-up for (8.94±2.94) months. By the end of follow-up, 34 patients had survived without tumor recurrence.Conclusion:The right Glisson pedicle approach based on the "APR triangle" and the anatomical resection of right hepatic segments with fluorescence negative staining were safe and feasible.

Objective:The study aimed to study the efficacy and safety of combined dual therapy using anti-programmed death (PD)-1 and tyrosine kinase inhibitor (TKI) with combined triple therapy using anti-PD-1, TKI and locoregional intervention triple therapy in patients with postoperative refractory recurrent liver cancer.Methods:Patients with postoperative refractory recurrent liver cancer who had undergone either anti-PD-1 and TKI dual therapy or anti-PD-1, TKI and locoregional intervention triple therapy between July 2016 and March 2019 at the First Medical Center, Chinese PLA General Hospital were retrospectively studied. Tumor responses were assessed by the modified response evaluation criteria in solid tumors and overall survival and progression free survival were compared. Adverse events were evaluated according to the National Cancer Institute Common Terminology Criteria for Adverse Events.Results:Of 63 patients who were included in this study, there were 25 patients in the dual therapy group (16 males and 9 females, aged 54.3±8.8 years) and 38 patients in the triple therapy group (31 males and 7 females, aged 55.5±8.4 years). The 1-year survival rate of the triple therapy group was significantly higher than the dual therapy group (94.5%vs 54.9%) ( P<0.01). The disease control rate was 64.0% (16/25) in the dual therapy group and 84.2% (32/38) in the triple therapy group, and the difference was not significant ( P>0.05). The incidence of treatment-related adverse events in the triple therapy group and the dual therapy group were 78.9% (30/38) and 80% (20/25), respectively. There was no treatment-related death in the 2 groups. Conclusions:Anti-PD-1 and TKI dual therapy and anti-PD-1, TKI and locoregional intervention triple therapy were effective and tolerable treatments for postoperative refractory recurrent liver cancer. The latter treatment had a significantly better clinical benefit on survival outcomes.

Objective To investigate the predictive factors affecting the efficacy of cyclophosphamide (CTX) combined with glucocorticoids in the treatment of idiopathic membranous nephropathy (IMN),and to evaluate the efficacy of calcineurin inhibitor (CNI) adjustment due to poor treatment.Methods A retrospective cohort study was conducted.Two hundreds and twenty-eight patients with IMN diagnosed by renal biopsy in the People's Hospital of Guangxi Zhuang Autonomous Region from January 1,2007 to December 1,2016 were enrolled.All subjects were treated with CTX in combination with glucocorticoids.The patients were divided into two groups:remission group and no remission group.Multivariable logistic regression analysis was used to determine the baseline clinical-pathological influencing factors for the remission of IMN in the enrolled patients.Results The number of total remission (including complete and partial remission) of the first CTX combined with glucocorticoid treatment in 228 patients with IMN was 188(82.5%).Among them,141 patients (61.8%) had complete remission (CR),the median time for CR was 8(6,12) months,and the median time for partial remission (PR) was 3(1,4) months.The median follow-up time for this study was 25(13,43) months.Compared with the remission group,the serum albumin level was lower in the non-remission group,the 24-hour urine protein content,the blood complement C3 and C4 levels were higher,and the pathological stage was milder (all P < 0.05).Multivariate logistic regression analysis suggested that the levels of baseline serum albumin,complement C4,and pathological stage were independent predictors of clinical remission in IMN patients.Twenty-four non-remission patients were treated with CNI.The overall response rate was 66.7%(16/24) at 6 months and 77.3%(17/22) at 12 months.Conclusions The levels of baseline albumin,blood complement C4,and pathological stage were independent predictors of clinical remission in IMN patients treated with CTX plus glucocorticoids.The non-remission patients with CTX combined with glucocorticoid therapy can still achieve a higher response rate after adjusting for CNI.
