Cellular senescence, an irreversible state of cell cycle arrest characterized by phenotypic changes and a specific secretory profile, plays a dual role in liver health and disease. Under physiological conditions, senescence aids organ repair and regeneration, but its accumulation due to aging or pathological stress significantly contributes to chronic liver diseases, including alcoholic liver disease, metabolic dysfunction-associated steatohepatitis, liver fibrosis, and hepatocellular carcinoma. Senescence is identified by a range of cellular and molecular changes, such as morphological alterations, expression of cell cycle inhibitors, senescence-associated β-galactosidase activity, and nuclear membrane changes. The onset of senescence in organ cells can affect the entire organism, primarily through the senescence-associated secretory phenotype, which has autocrine, paracrine, and endocrine effects on tissue microenvironments. The objective of this review is to offer a contemporary overview of the pathophysiological events involving hepatic senescent cells and to elucidate their role in the onset and progression of liver diseases, particularly through mechanisms like telomere shortening, genomic and mitochondrial DNA damage, and inflammation. Additionally, this review discusses the emerging senolytic therapies aimed at targeting senescent cells to delay or mitigate liver disease progression. The therapeutic potential of these interventions, alongside their safety and effectiveness, highlights the need for further research to refine these approaches and address unresolved problems in the field of hepatic cellular senescence.

ObjectiveTo explore the therapeutic effect of Huangliansan on atopic dermatitis （AD） model mice induced by 2， 4-dinitrochlorobenzene （DNCB）. MethodA total of 42 male BALB/c mice were randomly divided into normal group， model group， hydrocortisone group， low， medium， and high-dose groups （0.3， 0.6， 1.2 g·kg^-1） of Huangliansan oil， and water extract group （0.6 g·kg^-1） of Huangliansan. In addition to the normal group， DNCB was applied on the back of mice in other groups to establish the AD model. On the 15^th day after DNCB stimulation， each group was given the corresponding drug or solvent， and the changes in skin lesions， dermatitis score， and frequency of scratching were observed and recorded. Hematoxylin-eosin （HE） staining was used to observe the histopathological changes in the skin and spleen. Real-time fluorescent quantitative polymerase chain reaction （Real-time PCR） was used to detect mRNA levels of filaggrin （FLG）， lorophane （LOR）， and involucrin （IVL） in skin， as well as immunoglobulin E （lgE）， interleukin-4 （IL-4）， interleukin-6 （IL-6）， interleukin-1β （IL-1β）， tumor necrosis factor-α （TNF-α）， and interferon-γ （IFN-γ） in spleen. ResultCompared with the normal group， the model group showed symptoms of skin swelling and scab， and the score of dermatitis， the frequency of scratching， and the spleen index were increased （P<0.05）. The expression levels of FLG， LOR， and IVL in skin tissue were significantly decreased （P<0.01）， and the mRNA expressions of IgE， IL-4， IL-6， IL-1β， and TNF-α in the spleen were significantly increased， while the expression level of IFN-γ was significantly decreased （P<0.01）. Compared with the model group， the symptoms of skin erythema， scaly， and scab of mice in each drug group were alleviated to varying degrees， and the score of dermatitis， the frequency of scratching， and the spleen index were decreased （P<0.05， P<0.01）. In addition， the expression levels of FLG， LOR， and IVL in the skin of mice in the drug group were increased （P<0.05， P<0.01）， and the mRNA expression of IgE， IL-4， IL-6， IL-1β， and TNF-α in spleen were decreased. IFN-γ was increased （P<0.05， P<0.01）， and the lesions of the skin and spleen were improved to varying degrees. The medium-dose group of Huangliansan oil and hydrocortisone group had the most obvious manifestations （P<0.05， P<0.01）. The indexes in the medium-dose group of Huangliansan oil were better than those in the water extract group of Huangliansan. ConclusionHuangliansan may improve the expression level of skin barrier protein， inhibit the expression of helper T cell 2 （Th2）-related inflammatory factors， increase the expression of helper T cell 1 （Th1） inflammatory factors， restore the skin barrier function and Th1/Th2 balance in the spleen， regulate the inflammatory response in the spleen of AD mice， and thus relieve AD. Huangliansan oil is more effective than water extract.

Objective:Explore the characteristics of injury current changes in ventricular septal myocardium during left bundle branch area pacing (LBBAP) surgery.Methods:Retrospective analysis of clinical data of patients who underwent permanent pacemaker implantation at The Second People's Hospital of Wuxi in Jiangsu Province from January 2020 to November 2022. Among them, 42 patients were treated with LBBAP (LBBAP group) and 56 patients with Right ventricle septum pacing (RVSP group). Compare the conventional parameters such as threshold, perception, impedance during electrode implantation, damage current values at 0, 5, and 10 minutes before and after electrode rotation, and the correlation between damage current and conventional parameters. The measurement data is represented by xˉ± s, analysis of variance is used for comparison between multiple groups, t-test is used for comparison between two groups, and repeated measurement analysis of variance is used for comparison between two groups at multiple time points; Counting data is represented as an example (%), and inter group comparisons are made using χ 2 Inspection; Pearson correlation analysis was used to analyze the correlation between the two variables. Results:There was no statistically significant difference in pacing threshold, perception, and impedance between the two groups of electrode implantation surgery (all P>0.05). The damage current values at 0, 5, and 10 minutes before and after electrode rotation in the LBBAP group were higher than those in the RVSP group [(7.19±1.26) mV compared to (5.33±0.79) mV, (22.50±3.06) mV compared to (10.85±1.70) mV, (15.75±2.63) mV compared to (8.01±1.09) mV, (9.24±2.00) mV compared to (5.51±0.98) mV]. The damage current values at 0 minutes after electrode rotation in both groups were higher than before electrode rotation, and gradually decreased thereafter, After 10 minutes of electrode placement, the damage current value of the LBBAP group was still higher than the level before electrode rotation (all P<0.05), while there was no statistically significant difference between the RVSP group and the level before electrode rotation ( P>0.05). The damage current value at 0 minutes after the LBBAP group electrode was in place was positively correlated with ventricular septal thickness and left ventricular posterior wall thickness ( r values 0.45 and 0.46, P values 0.003 and 0.002, respectively), and negatively correlated with conventional pacing parameter impedance ( r=-0.32, P=0.037). There was no correlation with threshold and perception ( r values 0.08 and 0.01, P values 0.604 and 0.968, respectively). The damage current value at 0 minutes after the RVSP group electrode was in place was negatively correlated with the threshold ( r=-0.28, P=0.036). Conclusions:The COI value of LBBAP interventricular septum myocardium increased significantly after the electrode was rotated out. The COI value at 0 min after the electrode put in place was positively correlated with the interventricular septum thickness and left ventricular posterior wall thickness, and negatively correlated with the electrode impedance, but there was no correlation with threshold and perception.

【Objective】 To compare the current standards and explore the influencing factors for hemolysis rate of leukocyte-reduced red blood cells at the end of the preservation period, in order to formulate reasonable internal control indicators. 【Methods】 A retrospective analysis was performed on hemolysis rate of 427 samples of leukocyte-reduced red blood cells at the end of the preservation period in Nanning Blood Center from 2015 to 2022. Compared with the current standard for hemolysis rate at the end of the preservation period (GB 18469-2012 Quality Requirements for Whole Blood and Component Blood), the differences were analyzed, and the factors influncing the hemolysis rate were analyzed in terms of different blood donor groups. 【Results】 1) Among the 427 samples, the hemolysis rate of 418 (97.89%) did not exceed 0.4%, all lower than 0.8%; 2)the hemolysis rate of the male group was higher than that of the female group; 3) the hemolysis rate of the 18-29 years old group was lower than that of the 30-39 year old group and the 40-60 year old group, with statistically significant difference; 4) in terms of occupation, the hemolysis rate of students was the lowest, and the differences between groups were statistically significant; 5) no statistical significance was found in ethnicity and blood type. 【Conclusion】 Statistics indicated that gender, age, blood donation volume and occupation of blood donors were the influencing factors of hemolysis rate. The current standard is obviously higher in the qualified range of blood quality control in Nanning. It is advisable to formulate a reasonable quality control strategy with internal control index of hemolysis rate set <0.4%, which is conducive to making accurate evaluation of internal quality control and ensuring blood safety.

Objective:To explore the status of social alienation among survivors of nasopharyngeal carcinoma and analyze its influencing factors.Methods:This study was a cross-sectional study. From October 2021 to January 2022, 200 survivors of nasopharyngeal carcinoma reviewed in the radiotherapy department of the First Affiliated Hospital of Guangxi Medical University were investigated by General Data Questionnaire, General Alienation Scale (GAS), Cancer Fatigue Scale (CFS) and Self-Perceived Burden Scale (SPBS).Results:The total score of GAS in survivors of nasopharyngeal carcinoma was (37.47 ± 2.88) points. The total scores of GAS were positively correlated with the total score and each dimension score of CFS and SPBS ( r values were 0.312-0.524, all P<0.01). Multivariable linear regression showed that the duration of diagnosis, whether or not having hearing loss, the number of symptoms, cancer fatigue and self-perceived burden were the main influencing factors of social alienation in survivors of nasopharyngeal carcinoma( t values were -3.99-4.86, all P<0.05), which could explain 49% of the total variation. Conclusions:Clinical medical staff should attach importance to social alienation of surviors of nasopharyngeal carcinoma. More attention should be paid to patients with less than one year of diagnosis, a large number of symptoms and hearing loss, and targeted intervention should be conducted to reduce the degree of social alienation of patients and promote their integration into society.
