Locoregional therapy （LRT）， including transarterial chemoembolization， transarterial radioembolization， and various ablation techniques， is an important treatment method for hepatocellular carcinoma. Many studies in recent years have confirmed that LRT has a dual regulatory effect on tumor immune microenvironment. While LRT induces immunogenic cell death， activates dendritic cell-mediated and T cell-driven immunity， and triggers systemic antitumor responses， it concomitantly upregulates the adenosine signaling pathway， promotes the accumulation of TREM2⁺ macrophages， and enhances the expression of immunosuppressive factors， thereby forming an immunosuppressive microenvironment. At present， the combination of LRT and immune checkpoint inhibitors has shown a promising future and has promoted the exploration of novel targets within treatment-associated immunosuppressive pathways， such as adenosine， TREM2⁺ macrophages， and IL-6. This article summarizes the dual regulatory effect of LRT on immune microenvironment and highlights that multi-omics techniques and clinical trials should be used in the future to decipher its dynamic alterations， in order to optimize combination strategies， realize individualized precise treatment， and improve the prognosis of patients.

Objective To analyze the epidemiological characteristics of hepatitis E (HE) in Huai'an City from 2015 to 2024, and construct and validate the prediction effect of the Seasonal Autoregressive Integrated Moving Average (SARIMA) model, and to provide a scientific basis for HE prevention and control. Methods Data of reported HE cases in Huai'an City from January 2015 to December 2024 were extracted from the National Disease Control and Prevention Information System. Descriptive epidemiological methods were used to analyze the temporal, regional and population distribution characteristics of HE incidence. After data preprocessing, stationarity test and randomness test, the SARIMA model was constructed. The optimal model was selected by minimizing the Akaike Information Criterion (AIC). The model performance was evaluated by adjusted R-squared (Adj R²) and root mean square error (RMSE). The monthly incidence rate of HE in Huai'an City in 2025 was predicted and compared with the actual incidence data to validate the model. Results A total of 1 713 HE cases were reported in Huai'an City from 2015 to 2024, showing a fluctuating upward trend. Huaiyin District (339 cases) and Lianshui County (334 cases) were high-incidence areas. The cases were mainly concentrated in people aged 45 and above (83.3%), males (gender ratio 2.37:1) and farmers (70.8%). The optimal model was SARIMA (1,1,1)×(2,0,1)₁₂, with residual as white noise sequence. There was no statistical difference between the actual incidence and predicted value from January to August 2025 (P>0.05). Conclusion HE incidence in Huai'an has obvious aggregation and temporal fluctuation characteristics. The SARIMA model has a good prediction effect, which can provide reference for formulating targeted prevention and control strategies.

ObjectiveTo investigate the effect of Semaphorin 3A （Sema3A） on the progression of pathological cardiac hypertrophy. MethodsWild-type C57BL 6J mice， Sema3A global overexpressing （Sema3A/Cre-ER^TM） mice， and their littermate controls （Cre-ER^TM） were used， with 6 mice per group. A pressure-overload induced cardiac hypertrophy model was established via transverse aortic constriction （TAC）， with a sham-operated group （Sham） as the control. Cardiac hypertrophy was assessed by gross morphology， heart weight/body weight ratio （HW/BW）， heart weight/tibia length ratio （HW/HL）， and heart weight/lung weight ratio （HW/PW）. Cardiac function was evaluated by measuring ejection fraction （EF） and fractional shortening （FS） via echocardiography. In heart tissues， the mRNA level of atrial natriuretic peptide （ANP） and Sema3A were detected by RT-qPCR， Sema3A protein level was detected by western blot， morphological structure was detected by hematoxylin and eosin （HE） staining， level of fibrosis was detected by Masson’s trichrome staining， and angiogenesis was detected by immunohistochemical detection of CD31. For in vitro experiments， rat H9C2 cardiomyocytes were treated with angiotensin Ⅱ （Ang Ⅱ） to induce hypertrophy， with PBS-treated cells as the control. After 48 hours， the mRNA expression of ANP， B-type natriuretic peptide （BNP） and Sema3A were measured by RT-qPCR， and Sema3A protein level was assessed by western blot. ResultsAt the animal level， compared with the sham group， mice subjected to TAC showed significantly increased mRNA levels of ANP in cardiac tissue， as well as markedly elevated mRNA and protein levels of Sema3A （all P<0.05）. Compared with the Cre-ER^TM + TAC group， the Sema3A/Cre-ER^TM + TAC group exhibited more pronounced cardiac hypertrophy， greater ventricular wall thickening， higher HW/BW， HW/HL， and HW/PW ratios， more significant reductions in EF and FS， more severe cardiac fibrosis， and a significant decrease in cardiac CD31 expression levels （all P<0.05）. At the cellular level， compared with the control group， H9C2 cells treated with Ang Ⅱ displayed significantly increased mRNA levels of ANP and BNP， along with markedly elevated mRNA and protein levels of Sema3A （all P<0.05）. ConclusionSema3A promotes the progression of pressure overload-induced cardiac hypertrophy by inhibiting angiogenesis.

ObjectiveTo investigate the mechanism by which Kangxian Yixin prescription regulates the circular RNA 0006719 （circ0006719）/microRNA 6852-5p （miR-6852-5p）/transforming growth factor-β₁ （TGF-β₁）/Smad axis to ameliorate myocardial fibrosis in rats with dilated cardiomyopathy （DCM） and angiotensin Ⅱ （Ang Ⅱ）-induced activation of cardiac fibroblasts （CFs）. MethodsA DCM rat model was established by administration of furazolidone. The rats were divided into normal group， model group， captopril （CAP， 10.1 mg·kg^-1·d^-1） group， and low-， medium-， and high-dose Kangxian Yixin prescription groups （0.9， 1.8， 3.6 g·kg^-1·d^-1）， with 15 rats in each group. After modeling， the treatment groups received corresponding drug solutions by gavage， whereas the normal and model groups received an equal volume of normal saline for 60 consecutive days. Echocardiography was used to measure left ventricular end-systolic diameter （LVESD）， left ventricular end-diastolic diameter （LVEDD）， left ventricular ejection fraction （LVEF）， and left ventricular fractional shortening （LVFS）. Transmission electron microscopy （TEM）， hematoxylin-eosin （HE） staining， and Masson staining were used to observe myocardial ultrastructure， pathological changes， and collagen deposition. Immunohistochemistry （IHC） was used to detect the protein expression of collagen type Ⅰ alpha 1 （Col1A1） and collagen type Ⅲ（Col Ⅲ） in myocardial tissue. Real-time quantitative polymerase chain reaction （Real-time PCR）， Western blot， and fluorescence in situ hybridization （FISH） were used to detect the expression and localization of circ0006719， miR-6852-5p， fibrosis-related molecules， and TGF-β₁/Smad pathway-related molecules in myocardial tissue and CFs. CFs from neonatal rats were isolated and cultured in vitro. Cell Counting Kit-8 （CCK-8） assay was used to determine the optimal concentration of Kangxian Yixin prescription for subsequent intervention. An Ang Ⅱ-induced CF activation model was established， and the cells were divided into normal group， Ang Ⅱ group， Ang Ⅱ+CAP group， Ang Ⅱ+Kangxian Yixin prescription group， and Ang Ⅱ+Kangxian Yixin prescription+miR-6852-5p inhibitor group. CF viability and fibrosis-related molecular expression were detected. RNA immunoprecipitation （RNA IP） and dual-luciferase reporter assays were used to verify the targeting relationship between circ0006719 and miR-6852-5p. ResultsCompared with the normal group， the model group showed significantly increased LVESD and LVEDD， significantly decreased LVEF and LVFS， aggravated myocardial ultrastructural and histopathological injury， and significantly increased collagen volume fraction （CVF） in myocardial tissue （P<0.01）. The expression of circ0006719， Col1A1 mRNA， Col ⅢmRNA， and Col1A1， Col Ⅲ， TGF-β₁， Smad3， and Smad4 proteins in myocardial tissue was significantly upregulated， whereas miR-6852-5p expression and Smad7 protein expression were significantly downregulated （P<0.01）. Compared with the model group， the CAP group and the high- and medium-dose Kangxian Yixin prescription groups showed varying degrees of improvement in cardiac function， myocardial fibrosis， circ0006719/miR-6852-5p expression， and TGF-β₁/Smad pathway-related indicators， with more pronounced improvements in the CAP group and the high-dose Kangxian Yixin prescription group （P<0.05， P<0.01）. In in vitro experiments， 2.0 g·L^-1 was determined as the optimal concentration of Kangxian Yixin prescription for subsequent intervention. Compared with the normal group， the Ang Ⅱ group showed significantly increased CF viability， significantly upregulated expression of circ0006719， Col1A1 mRNA， α-smooth muscle actin （α-SMA） mRNA， and Col1A1， α-SMA， TGF-β₁， Smad3， and Smad4 proteins in CFs， and significantly downregulated miR-6852-5p expression and Smad7 protein expression （P<0.01）. Compared with the Ang Ⅱ group， the Ang Ⅱ+CAP group and the Ang Ⅱ+Kangxian Yixin prescription group showed markedly decreased CF viability and fibrosis-related mRNA and protein expression， markedly increased miR-6852-5p expression， and markedly attenuated TGF-β₁/Smad pathway activation （P<0.05， P<0.01）. Compared with the Ang Ⅱ+Kangxian Yixin prescription group， the Ang Ⅱ+Kangxian Yixin prescription+miR-6852-5p inhibitor group showed significantly increased CF viability （P<0.01）， markedly increased expression of circ0006719， Col1A1 mRNA， and Col1A1， TGF-β₁， and Smad4 proteins in CFs， and markedly decreased miR-6852-5p expression （P<0.05， P<0.01）. RNA IP and dual-luciferase reporter assays showed a targeting binding relationship between circ0006719 and miR-6852-5p （P<0.01）. ConclusionKangxian Yixin prescription may alleviate myocardial collagen deposition and myocardial fibrosis， improve cardiac function in DCM rats， and inhibit Ang Ⅱ-induced abnormal activation of CFs. Its mechanism may be associated with downregulation of circ0006719， restoration of miR-6852-5p expression， and inhibition of the TGF-β₁/Smad pathway.

Objective:To analyze the impact and mechanism of grassroots Party building in public hospitals on departmental business, and to provide reference for promoting the integration and mutual promotion of Party building and business.Methods:In November 2023, a self-designed questionnaire was used to survey clinical medical staff in a tertiary hospital in Wuhan. A cluster random sampling method was employed to investigate the evaluation of grassroots Party building work by clinical medical staff and the role of grassroots Party building in departmental business. Descriptive quantitative analysis was conducted on the questionnaire data. From November to December 2023, typical sampling was used to select Party branch committee members from clinical and medical technology departments of the hospital for semi-structured interviews. The interview content included the status of grassroots Party building work, its role in departmental business development, and the underlying mechanisms. Grounded theory was used for three-level coding of the interview data, and role theory was applied to analyze the mechanism by which grassroots Party building promotes business development.Results:A total of 1 124 valid questionnaires were collected, covering personnel from various sequences, including medical, nursing, technical, and pharmacy staff. Over 95% of the respondents rated the Party branch work highly, and more than 94% believed that grassroots Party building had a positive impact on the department′s medical care, teaching, research, talent team building, management, and cultural construction. The analysis using grounded theory and role theory revealed that the promotion of departmental business by grassroots Party building mainly originated from three aspects of standardization and normalization construction of Party branches, participation of Party branches in departmental management, and the development of characteristic activities based on Party building carriers. These three aspects enhanced personal responsibility, discipline, and service awareness through five personal-level targets (correcting work attitudes, leading by example among Party members, strengthening integrity in professional practice, improving professional skills, and improving working methods). This, in turn, facilitated medical staff to better identify their role positioning, standardize role behavior, and enhance role learning. At the departmental level, seven targets (expanding channels for departmental transparency, emphasizing practical performance, Party branch involvement in important departmental matters, enhancing external communication, increasing emotional identification, improving internal communication, and strengthening integrity building) were identified to promote fairness and justice, democratic decision-making, external cooperation, unity, and a clean atmosphere within the department. This further improved role evaluation, created an atmosphere conducive to role learning, helped strengthen role identification, and guided role standardization.Conclusions:Grassroots Party building of public hospital has a positive impact on department business work and is widely recognized by clinical medical staff. Different Party building activities have different pathways of influence. It is recommended to conduct targeted Party building activities based on actual needs.

Establishing a scientific talent classification evaluation mechanism is of great significance for public hospitals to motivate and guide the career development of various types of talents and to promote the high-quality development of the health and medical care industry. However, university-affiliated hospitals had long faced issues such as an imperfect talent classification evaluation system, difficulty in setting evaluation indicators, a relatively monolithic evaluation method, and insufficient application of evaluation results. In 2019, Union Hospital, Tongji Medical College, Huazhong University of Science and Technology, initiated a talent stratification and classification management mechanism. The hospital established separate evaluation indicator systems for clinical, research, and teaching talents, and adhered to a value orientation that equally emphasizes medical care, teaching, and research. Additionally, a diversified evaluation mode was constructed, led by the hospital with the participation of peers and the public. Emphasis was also placed on linking evaluation results with talent development, rewards, and excellence awards. The initiative has achieved positive outcomes and can serve as a reference for talent management in other university-affiliated hospitals and relevant departments.

OBJECTIVE To explore the changes of microribonucleic acid(miR)-223,miR-155 and miR-125 in the neonates with sepsis and analyze the distribution of pathogens so as to provide bases for clinical diagnosis and treatment of neonates with sepsis.METHODS A total of 39 neonates with sepsis who were treated in Jinan Second Maternal and Child Health Hospital from May 2021 to May 2023 were enrolled in the study and were assigned as the study group,meanwhile,42 healthy neonates who were born in the hospital were chosen as the control group.The distribution and drug resistance of the pathogens isolated from the neonates of the study group were statistically analyzed.The relative expression levels of peripheral blood miR-223,miR-155 and miR-125 were com-pared between the two groups,and the values of the three indexes in diagnosis of neonatal sepsis were analyzed.RESULTS Totally 46 strains of pathogens were isolated from the 39 neonates with sepsis,20 of which were Escherichia coli,and 10 were Staphylococcus aureus.The E.coli strains were resistant to ampicillin,tetra-cycline,ciprofloxacin and cefazolin;the S.aureus strains were resistant to penicillin,erythromycin,cefazolin and clindamycin,with the drug resistance rates higher than 50％.The expression level of miR-223 of the study group was 2.13±0.70,higher than that of the control group,the expression level of miR-125 of the study group was 0.92±0.30,higher than that of the control group;while the expression level of miR-155 of the study group was 2.08±0.68,lower than that of the control group(P＜0.05).The area under the curve(AUC)of the joint detec-tion of miR-223,miR-155 and miR-125 was 0.945 in diagnosis of neonatal sepsis,with the sensitivity 92.31％,the specificity 88.10％.CONCLUSIONS E.coli and S.aureus are dominant among the pathogens isolated from the neonates with sepsis.The neonates with sepsis show abnormal expressions of peripheral blood miR-223,miR-155 and miR-125,and the joint detection of the three indexes has high value in diagnosis of neonatal sepsis.

Objective To explore the distribution of clinical features and the correlation between TCM syndromes and laboratory indicators in patients with atrial fibrillation.Methods Retrospective analysis was performed on 924 patients with atrial fibrillation who were hospitalized in Xiyuan Hospital of China Academy of Chinese Medical Sciences from January 2016 to December 2023.The distribution pattern of TCM syndromes in patients with atrial fibrillation was analyzed,and the correlation between TCM syndromes and age,gender,past history,inflammatory indicators and biochemical indicators were explored.Results The study included 924 atrial fibrillation patients,predominantly female and mostly middle-aged or elderly.The main TCM syndrome types were qi-yin deficiency syndrome,qi deficiency and blood stasis syndrome,phlegm fire disturbance syndrome and phlegm blood stasis obstruction syndrome.Correlation analysis showed that patients with qi-yin deficiency syndrome had lower total protein and globulin,and the two were negatively correlated;qi deficiency and blood stasis syndrome were positively correlated with high density lipoprotein cholesterol levels;patients with phlegm fire disturbance syndrome were mostly male,younger in age and had a higher proportion of smoking history.They were negatively correlated with gender,age,and smoking history,and positively correlated with comorbidities of coronary heart disease,white blood cells,neutrophils,total protein,albumin,and globulin;patients with phlegm blood stasis obstruction syndrome were positively correlated with creatine kinase and uric acid,with statistical significance(P<0.05).Conclusion The TCM syndrome of atrial fibrillation is mainly characterized by qi-yin deficiency,and the proportion of phlegm and fire disturbance syndrome is increasing year by year.There is a correlation between the TCM syndromes of atrial fibrillation and clinical features(gender,age,past history),laboratory indicators such as inflammatory markers(WBC,NE,SII,NLR),total proteins,globulins,high density lipoprotein cholesterol,creatine kinase and uric acid,which can provide a guide to the"differentiation of disease,syndromes and body"in the diagnosis of atrial fibrillation.
