Objective　To investigate the effect of andrographolide on enterovirus 71 (EV71) and coxsackievirus A16 (CA16) in vitro. Methods Cytopathic CPE assay and thiazolyl blue tetrazolium bromide (MTT) assay were used to determine the maximum non-toxic dose of andrographolide on RD cells and the inhibitory effect of andrographolide on EV71 and CA16 infection in vitro. The effects of andrographolide on the virus VP1 gene and cellular inflammatory factors (IL-1β, IL-6, and TNF-α) at gene levels were detected by quantitative fluorescence PCR. Results MTT results showed that the maximum non-toxic dose of andrographolide on RD cells was 78.00 μg/mL. Upon infection with hand-foot-mouth disease viruses, cells treated with andrographolide solutions at concentrations of 78.00, 39.00, 19.50, 9.75, 4.88, and 2.44 μg/mL showed increased survival rates to (82.41±1.76)%, (79.54±2.91)%, (81.02±1.99)%, (71.81±2.26)%, (52.87±1.51)%, and (50.41±0.93)% for EV71 and (81.00±0.64)%, (79.72±1.38)%, (61.59±3.47)%, (53.37±0.53)%, (52.41±1.37)%, and (43.69±0.40)% for CA16, respectively, indicating a significant reduction in the cytopathic effect caused by EV71 and CA16. When infected with hand-foot-mouth viruses and treated with andrographolide solutions at concentrations of 78.00, 39.00, 19.50, and 9.75 μg/mL, the expression levels of VP1 in EV71 and CA16, along with pro-inflammatory factors IL-1β, IL-6, and TNF-α in RD cells, were significantly lower compared to the virus control group. These results indicated that after infection with hand-foot-mouth viruses, treatment with andrographolide solution significantly inhibits the expression of the VP1 gene and reduces the mRNA levels of IL-1β, IL-6, and TNF-α. Conclusions Andrographolide exhibits obvious in vitro antiviral effects against EV71 and, potentially through the inhibition of the expression of pro-inflammatory factors IL-1β, TNF-α, and IL-6, thereby exerting its antiviral effects.

HDAC7, a member of class IIa HDACs, plays a pivotal regulatory role in tumor, immune, fibrosis, and angiogenesis, rendering it a potential therapeutic target. Nevertheless, due to the high similarity in the enzyme active sites of class IIa HDACs, inhibitors encounter challenges in discerning differences among them. Furthermore, the substitution of key residue in the active pocket of class IIa HDACs renders them pseudo-enzymes, leading to a limited impact of enzymatic inhibitors on their function. In this study, proteolysis targeting chimera (PROTAC) technology was employed to develop HDAC7 drugs. We developed an exceedingly selective HDAC7 PROTAC degrader B14 which showcased superior inhibitory effects on cell proliferation compared to TMP269 in various diffuse large B cell lymphoma (DLBCL) and acute myeloid leukemia (AML) cells. Subsequent investigations unveiled that B14 disrupts BCL6 forming a transcriptional inhibition complex by degrading HDAC7, thereby exerting proliferative inhibition in DLBCL. Our study broadened the understanding of the non-enzymatic functions of HDAC7 and underscored the importance of HDAC7 in the treatment of hematologic malignancies, particularly in DLBCL and AML.

Guided by ZHANG Jiebin's "water-fire of life gate theory"， this paper explored the etiology， pathoge-nesis， and syndrome differentiation-based treatment approach for esophageal cancer. It is proposed that the core pathogenesis of esophageal cancer， derived from the imbalanced state of water and fire in life gate， can be summarized into three manifestations. Firstly， decline of life gate fire leads to failure of qi transformation and accumulation of phlegm and blood stasis； secondly， fire fails to warm the earth resulting in dysfunctional ascending and descending， and qi stagnation and blood stasis； thirdly， deficiency of life gate water contributs to proliferation of cancerous toxins and physical deterioration. In terms of treatment， guided by ZHANG's treatment principles for dysphagia， three treatment methods are proposed， warming and tonifying kidney yang to promote qi transformation through steaming action， warming and nourishing the spleen and stomach to restore central pivot movement， and nourishing kidney water to replenish essence and blood， then support bodily nourishment. Clinical case examples are provided to illustrate the application of these methods.

BACKGROUND:Epigenetics,as an important regulation mode of gene expression network,has been proved to play an important role in the occurrence and development of aortic aneurysm mediated by vascular smooth muscle cell remodeling. OBJECTIVE:To review the epigenetic regulation mechanism underlying vascular smooth muscle cell remodeling during the occurrence and progression of aortic aneurysm. METHODS:Related articles published from 1970 to 2022 were retrieved from PubMed,Web of Science and CNKI databases.The keywords were"Aortic aneurysm,Vascular smooth muscle,Smooth muscle cells,Epigenetic,DNA methylation,Histone modification,Non coding RNA"in English and Chinese.Ultimately,we included 71 articles for review. RESULTS AND CONCLUSION:Epigenetic modification can influence the occurrence and progression of aortic aneurysm by targeting vascular smooth muscle cell remodeling and extracellular matrix degradation.Targeted epigenetic modification can play a key role in aortic aneurysm treatment,delaying the disease and improving the prognosis.Epigenetic related enzymes,such as DNA methylesterases and histone-modifying enzymes,can influence the progression of aortic aneurysm by regulating vascular smooth muscle cell remodeling,including cell proliferation,migration and apoptosis,and can be used as targets for drug therapy.The research of epigenetic modification on aortic aneurysm is still in the basic research stage and some epigenetic modification mechanisms have not yet been explored.With the development of medical research,targeted epigenetic modification is expected to achieve new breakthroughs in the treatment of aortic aneurysm and clinical transformation.

Objective:To investigate the impact of rosacea on patients＇ quality of life and mental health, and to analyze variations across different subtypes, gender, sun exposure, smoking status, ethnicity, and educational levels, as well as patients＇ demands for treatment.Methods:It was a cross-sectional study from October 2022 to January 2024, 177 rosacea patients from the Department of Dermatology, the First Affiliated Hospital of Kunming Medical University were surveyed. The cohort comprised 36 males and 141 females, with a median age of 35 (29, 44) years. Data collected through questionnaires included general information, Dermatology Life Quality Index (DLQI), Generalized Anxiety Disorder-7 (GAD-7), Patient Health Questionnaire-9 (PHQ-9), and Patient Need Questionnaire (PNQ). Statistical analysis was conducted on the collected data.Results:The median DLQI score was 10 (3, 15), indicating moderate impact. The median GAD-7 score was 5 (2, 7), suggesting mild anxiety; while the median PHQ-9 score was 6 (2, 9), indicating mild depression. Female patients scored higher in both DLQI and GAD-7 than males ( P<0.05). Papulopustular subtypes had higher DLQI and GAD-7 scores compared to other subtypes ( P<0.01). Patients with lower education levels scored higher in DLQI and GAD-7 than those with higher education ( P<0.01), and non-smokers had higher GAD-7 scores than smokers ( P<0.05). Significant positive correlations were found between DLQI and PHQ-9 ( r=0.39, P<0.01), and DLQI and GAD-7 ( r=0.51, P<0.01), as well as between PHQ-9 and GAD-7 ( r=0.59, P<0.01). Regarding treatment needs, 159 patients (89.8%) expressed a strong desire for a clear diagnosis and treatment plan, and the same number wished for a complete resolution of all skin lesions. Female patients consistently demonstrated significantly stronger demands in all 28 treatment need items (all P<0.05). Conclusions:Rosacea significantly affects patients＇ quality of life and mental health, particularly among females, individuals with papulopustular subtypes, and those with lower education levels. There is a strong demand for definitive diagnostic and therapeutic plans, especially among female patients.

Objective:To investigate the association between metabolic syndrome (MS) components and renal cell cancer in Chinese males.Methods:All male employees and retirees of the Kailuan Group were recruited in the Chinese Kailuan Male Cohort Study. They had been experienced routine physical examinations ever two years since May 2006. A total of 104 274 males were prospectively observed by 31 December 2015. Information on demographics, height, weight, blood glucose, blood lipid, blood pressure, as well as the information of incident renal cell cancer cases were collected at the baseline investigation by questionnaire, physical measurement and laboratory test. Cox proportional hazards regression models were used to evaluate the association between baseline MS and MS components (body mass index, blood glucose, blood lipid, blood pressure) and the risk of renal cell cancer in males.Results:A total of 104 274 males were recruited in our study with a age of (51.21±13.46) years, with 823 892.96 person-years follow-up and the median follow-up time was 8.88 years. A total of 131 new renal cell cancer cases were identified in the Kailuan male cohort study, and the crude incidence density was 15.90 per 100,000 person-years. Compared with no MS, the hazard ratios ( HR) (95% CI) of MS was 1.97 (1.32-2.94).When compared with normal level, the HR (95% CI) of obesity or overweight, hypertension, and dyslipidemia was 1.49 (1.04-2.14), 1.56 (1.06-2.29), and 1.77(1.23-2.54), after adjusting for potential confounding factors (i.e., age, education, income, smoke, and alcohol drink), respectively. In addition, a statistically significant trend ( P for trend<0.001) of increased renal cell cancer risk with an increasing number of abnormal MS components was observed. Conclusion:Obesity or overweight, hypertension, dyslipidemia and MS may increase the risk of renal cell cancer for Chinese males.

Gastric cancer is one of the most common cancer. Studies have been conducted to evaluate the association between anthropometric indicators and gastric cancer, but the results were inconsistent. Therefore, a literature retrieval was conducted by using PubMed and Wanfang databases to summarize the latest research progress in the cohort study of the association between anthropometric indicators and the risk for gastric cancer. It was found that both general obesity and abdominal obesity might increase the risk for gastric cancer, while the association between underweight and gastric cancer needs further study. This paper summarizes the progress in the cohort study of association between anthropometric indicators for the risk for gastric cancer in order to provide evidence for the prevention and control of gastric cancer.

Objective: To investigate whether elevated levels of C-reactive protein (CRP) and neutrophil (NE) in the blood is associated with an increased risk of lung cancer incidence. Methods: From 2006 to 2007, all employees and retirees from Kailuan (Group) Limited liability Corporation were included in this Kailuan Cohort study. The last follow-up date was December 2015. Data on new cases of lung cancer were collected, and multivariable Cox proportional hazards regression models were used to the relationship between baseline CRP and NE at baseline and risk of lung cancer. Results: A total of 92 735 participants were enrolled in this study. During the follow-up, 850 new cases of lung cancer were identified. All subjects were divided into four groups according to the combination level of CRP and NE at baseline: CRP≤3 mg/L and NE≤4×10⁹/L(Group A), CRP≤3 mg/L and NE>4×10⁹/L(Group B), CRP>3 mg/L and NE≤4×10⁹/L(Group C), CRP>3 mg/L and NE>4×10⁹/L(Group D). The cumulative incidence of lung cancer were 950/100 000, 1 030/100 000, 1 081/100 000 and 1 596/100 000 in these four groups, respectively (P<0.001). Multivariate Cox proportional risk model showed that participants from Group D had an significantly increased 72% risks of lung cancer when compared to Group A (95% CI: 1.40~2.12, P<0.001). Stratified analyses gender showed that males in Group D had higher risk of lung cancer when compared with participants in Group A (HR=1.73, 95% CI: 1.40~2.15, P<0.001). Conclusion Elevated levels of CRP and NE might increase the risk of lung cancer.
