Over the past three decades， China has made significant progress in the prevention and control of viral hepatitis， and the incidence rates of new-onset pediatric hepatitis B virus infections and acute viral hepatitis in the population have reduced to a relatively low level； however， there is still a heavy disease burden of chronic viral hepatitis in China， which severely affects the health status of the population. This study systematically summarizes the achievements of viral hepatitis prevention and control in China， analyzes existing problems and challenges， and proposes comprehensive prevention and control strategies and measures to eliminate viral hepatitis as a public health threat based on the national conditions of China， in order to provide a reference for related departments in China on how to achieve the action targets for eliminating viral hepatitis as a public health threat by 2030.

Algorithmic systems based on artificial intelligence(AI)and machine learning(ML)have undergone rapid advancement in recent years, demonstrating extensive application across diverse ophthalmic disorders. Owing to the public availability of multiple global databases, significant progress has been achieved in the training and development of AI-integrated algorithms utilizing multimodal ophthalmic imaging modalities, including fundus photography and optical coherence tomography(OCT). These advancements have established a foundation for precision medicine and efficient healthcare delivery. The diagnosis of macular diseases relies on the identification of subtle alterations in tissue anatomy, where AI demonstrated exceptional performance in detecting intraocular biomarkers and evaluating anatomical changes during disease progression, with particularly prominent utility in the field of macular pathologies. This article provides a comprehensive review of the current applications of AI in macular diseases, aiming to synthesize existing research achievements and current challenges, while proposing visionary prospects for the broader implementation of AI in ophthalmology and even systemic medicine in the future.

Objective:To observe the changes in choroidal morphology and blood perfusion in patients with macular edema secondary to retinal vein occlusion (RVO) after intravitreal injections of ranibizumab.Methods:A cohort study was performed.A total of 157 patients (157 eyes) with macular edema secondary to monocular acute retinal vein occlusion (RVO) were enrolled in the Third People's Hospital of Dalian from January 2022 to March 2023.There were 66 cases (66 eyes) with central retinal vein occlusion (CRVO) and 91 cases (91 eyes) with branch retinal vein occlusion (BRVO).All patients were treated with 3+ pro re nata (PRN) regimen of ranibizumab.Before and 1 month after each injection, the central retinal thickness of the macula was measured by optical coherence tomography (OCT).Clear images of the choroid were obtained using the OCT enhanced depth scan mode.Subfoveal choroidal thickness (SFCT), the nasal choroidal thickness at 1 500 μm of macula (CT N1.5 mm), the temporal choroidal thickness at 1 500 μm of macula (CT T1.5 mm) were measured and mean macular thickness (CT Mean) was calculated.Binarization of choroidal images processed by ImageJ software was used to analyze luminal area (LA), stromal area (SA) and total choroidal area (TCA), and choroidal vascularity index (CVI) was calculated.This study adhered to the Declaration of Helsinki and was approved by the Ethics Committee of the Third People's Hospital of Dalian (No.2023-145-001).Results:SFCT, CT T1.5 mm, CT N1.5 mm, CT Mean, LA, SA, TCA and CVI of RVO eyes were higher than those of the contralateral eyes and the differences were statistically significant (all P<0.01).CT Mean in CRVO group was (326.99±64.92)μm, which was higher than (299.80±73.08)μm in BRVO group, with a statistically significant difference ( t=2.41, P=0.02).Baseline CVI values in CRVO group and BRVO group were (72.50±5.62)% and (72.33±5.85)%, respectively, with no significant difference ( t=0.187, P=0.85).In eyes with RVO, CRVO and BRVO, SFCT, CT T1.5 mm, CT N1.5 mm, CT Mean, LA, SA, TCA and CVI after every injection were lower than the baseline and the differences were statistically significant (all P<0.05).In eyes with CRVO, there was no significant difference in LA and CVI between first and second injections (both P>0.05), and SFCT, CT T1.5 mm, CT N1.5 mm, CT Mean, SA and TCA after second injection were lower than those after first injection with statistically significant differences (all P<0.05).In eyes with BRVO, there was no significant difference in SA and CVI between first and second injections (both P>0.05), and SFCT, CT T1.5 mm, CT N1.5 mm, CT Mean, LA and TCA after second injection were lower than those after first injection with statistically significant differences (all P<0.05).In eyes with RVO, CRVO and BRVO, there was no significant difference in SFCT, CT T1.5 mm, CT N1.5 mm, CT Mean, SA, TCA and CVI between second and third injections (all P>0.05). Conclusions:After intravitreal injection of ranibizumab, the choroidal thickness becomes thinner and CVI decreases in eyes with macular edema secondary to RVO, and remain relatively stable after the second injection.

Objective To investigate the expression of the circular RNA circ-PHC3 in cervical cancer tissues and its regulatory mechanisms in the proliferation,migration,and invasion of cervical cancer cells.Methods The expression levels of circ-PHC3 in cervical cancer tissues and adjacent non-tumor tissues were analyzed using the GEO database.The correlation between circ-PHC3 expression and the clinical stage as well as prognosis of cervical cancer patients was also evaluated.The expression of circ-PHC3 in cervical cancer cell lines HCC94,C33A,HeLa,HCC1106,and SiHa was detected by real-time quantitative polymerase chain reaction(qRT-PCR).The cell line with the highest circ-PHC3 expression was selected for transfection with a circ-PHC3 inhibitor.The interaction between circ-PHC3 and miR-1179 was validated using a dual luciferase reporter gene assay.The expression levels of miR-1179 in transfected cells were further assessed by qRT-PCR.Functional assays,including colony formation,flow cytometry,wound healing,and Transwell assays,were conducted to evaluate cell proliferation,cell cycle progression,migration,and invasion,respectively.Western blot analysis was performed to determine the expression of key proteins associated with proliferation,migration,and invasion in circ-PHC3-modulated cells.Finally,in vivo experiments were carried out to investigate the impact of circ-PHC3 silencing on the growth and metastasis of cervical cancer cells in animal models.Results The expression level of circ-PHC3 in cervical cancer tissues was significantly higher than that in adjacent normal tissues(P<0.01).Furthermore,circ-PHC3 expression was significantly associated with the clinical stage of cervical cancer(P<0.01).Patients with high circ-PHC3 expression exhibited a notably lower survival rate compared to those with low circ-PHC3 expression(P<0.01).In cervical cancer cell lines including HCC94,C33A,HeLa,HCC1106,and SiHa,circ-PHC3 expression was markedly upregulated(all P<0.01),with the highest expression observed in HCC1106 cells(P<0.01).Circ-PHC3 was found to directly interact with miR-1179(P<0.01),and silencing circ-PHC3 significantly increased miR-1179 expression(P<0.01).Transfection of HCC1106 cells with a circ-PHC3 inhibitor significantly suppressed cell proliferation,migration,and invasion(all P<0.01),and induced cell cycle arrest(P<0.01);these effects were partially reversed by co-transfection with a miR-1179 inhibitor(all P<0.05).In HCC1106 cells with circ-PHC3 knockdown,the expression levels of key proteins associated with proliferation,migration,and invasion—Cyclin E,CDK2,MMP-9,and N-cadherin—were significantly reduced(all P<0.01),and this reduction was partially attenuated by miR-1179 inhibition(all P<0.01).In vivo experiments further demonstrated that circ-PHC3 knockdown significantly inhibited tumor growth and metastasis of HCC1106 cells(all P<0.01).Conclusions Circ-PHC3 is highly expressed in cervical cancer tissues,and its overexpression is significantly correlated with poor prognosis in patients with cervical cancer.Knockdown of circ-PHC3 upregulates the expression of miR-1179 and suppresses the proliferation,migration,and invasion of cervical cancer cells.

Objective To investigate the susceptibility and infection characteristics of dengue virus(DENV)in cells derived from diverse tissues of tree shrews and to provide a basis for expanding the repertoire of DENV-permissive cell models in this species.Methods DENV was inoculated at a multiplicity of infection(MOI)of 0.02 into tree shrew skin fibroblasts(TSFs),primary tree shrew renal epithelial cells(pTRECs),tree shrew aortic endothelial cells(TAECs),tree shrew aortic smooth muscle cells(TASMCs),tree shrew hepatocytes(THs),tree shrew corneal stromal cells(TCSCs),tree shrew brain microvascular endothelial cells(TBMECs),and tree shrew retinal microvascular endothelial cells(TRMECs).C6/36,Vero,A549,and BHK-21 cells(commonly used for DENV propagation)were used as positive controls.Over 6 days post-infection,cellular cytopathic effects were monitored at 12-hour intervals using an inverted microscope,viral RNA loads in cell lysates were quantified by real-time fluorescent quantitative PCR to generate proliferation curves,and viral titers were determined by plaque assay.Results Seven types of tree shrew cells,except TRMECs,were susceptible to DENV.Prolonged infection induced pronounced cytopathic effects,including cell rounding,detachment,necrosis,and lysis,across all susceptible cells.The viral RNA loads detected in lysates of pTRECs,TBMECs,TASMCs,TAECs and THs,approached those of positive controls(≥4×107 copies/μL).Infectious progeny viruses were produced by these five cell types,with three(TAECs,3.13×105 PFU/mL;THs,2.03×105 PFU/mL;pTRECs,1.58×105 PFU/mL)exhibiting titers comparable to C6/36(3.85×10 5 PFU/mL)and earlier viral harvests.Conclusion DENV exhibits broad susceptibility to tree shrew cells of multiple tissue origins,with proliferation rates surpassing those of conventional cell lines sourced from other species.TAECs,THs,and pTRECs are particularly suitable for large-scale DENV proliferation,suggesting their potential involvement in in vivo infection.

Objective:To investigate the clinical features and predictive indicators of children with recurrent simple febrile seizures, providing theoretical guidance for the early identification of such patients in clinical practice.Methods:This study is a single-center, retrospective analysis. It included 152 children with febrile seizures who were admitted to Department of Emergency, Hangzhou Children's Hospital from January 2021 to December 2023. Based on whether multiple episodes of simple febrile seizures occurred within 24 hours, the children were divided into a recurrent simple febrile seizure group ( n = 44) and a simple febrile seizure group ( n = 108). Demographic characteristics, clinical data, and laboratory test results were collected. Statistical analysis was performed using univariate and multivariate logistic regression, correlation analysis, and receiver operating characteristic curves. Results:Among the 152 children with febrile seizures included in this study, 44 (28.95%) were diagnosed with recurrent simple febrile seizures. Children with recurrent simple febrile seizures had lower temperatures upon admission, were younger at the time of their first febrile seizure, and had a higher proportion of cases where the time interval from fever to seizure was < 12 hours ( t = 2.84, 4.25, 8.45, all P < 0.05). Pearson correlation analysis showed that recurrent simple febrile seizures were negatively correlated with admission temperature and age at first febrile seizure ( r = -0.599, -0.609, both P < 0.001) and positively correlated with the time interval from fever to seizure ( r = 0.568, P = 0.004). Logistic regression analysis indicated that age at first febrile seizure and a time interval from fever to seizure of ≥ 12 hours were influential factors of recurrent simple febrile seizures ( OR = 2.864, 2.145, P = 0.004, 0.007). Receiver operating characteristic curve analysis revealed that admission temperature, age at first febrile seizure, a time interval from fever to seizure of ≥ 12 hours, and their combination were all effective in detecting recurrent simple febrile seizures. However, the combined assessment had higher sensitivity and specificity than any single assessment, with a sensitivity of 88.60%, specificity of 89.80%, a cutoff value of 0.840, and an area under the curve of 0.886. Conclusions:Lower admission temperatures, younger age at the time of the first febrile seizure, and a time interval of < 12 hours from fever to seizure are associated with an increased likelihood of simple febrile seizures developing into recurrent simple febrile seizures.

Objective To investigate the effect of forsythigenin on the malignant progression of lung cancer cells by regulating the cyclic adenosine monophosphate/exchange protein directly activated by cAMP1/Ras-associated protein 1(cAMP/EPAC1/RAP1)signaling pathway.Methods Lung cancer cell line A549 was cultured in vitro and grouped into the control group,the low dose forsythigenin group(25 mg/L),the medium dose forsythigenin group(50 mg/L),the high dose forsythigenin group(100 mg/L),the high dose forsythigenin+specific increase in intracellular cAMP content(pertussis toxin PTX)group(100 mg/L forsythigenin+5 μmol/L PTX)and high dose forsythigenin+EPAC1 antagonist(ESI-09)group(100 mg/L forsythigenin+1.5 μmol/L ESI-09).CCK-8 experiment was applied to detect cell proliferation.Scratch test was applied to detect cell migration.Flow cytometry was applied to detect cell apoptosis.Transwell was applied to detect cell invasion.ELISA method was applied to detect cAMP level in cell supernatant.Western blot assay was applied to detect expression levels of cAMP/EPAC1/RAP1 signaling pathway proteins and apoptotic proteins[B lymphoblastoma-2(Bcl-2)and Bcl-2 associated X protein(Bax)].Results Compared with the control group,the OD450 value of A549 cells,number of cell invasions,scratch healing rate,level of cAMP,expression levels of Bcl-2,EPAC1 and RAP1 proteins were significantly reduced in the low dose,medium dose and high dose forsythigenin groups,and the expression of Bax protein and the rate of cell apoptosis were significantly increased in a dose-dependent manner(P＜0.05).Compared with the high-dose forsythigenin group,the OD450 value of A549 cells,scratch healing rate,number of cell invasions,level of cAMP,expression levels of Bcl-2,EPAC1 and RAP1 proteins were obviously increased in the high-dose forsythigenin+PTX group,the expression of Bax protein and the apoptosis rate were obviously reduced(P＜0.05).Levels of all indexes in the high dose forsythigenin+ESI-09 group were opposite.Conclusion Forsythigenin inhibits proliferation,migration,and invasion of A549 cells and promotes apoptosis by down-regulating the cAMP/EPAC1/RAP1 signaling pathway.

Objective To explore the clinical efficacy of different mucosal incision methods in endoscopic submucosal dissection(ESD)for the treatment of gastric submucosal tumors.Methods A retrospective analysis was conducted on the clinical data of 30 patients with gastric submucosal tumors treated with ESD from July 2022 to March 2024.They were divided into a circular group(n=15)and a longitudinal group(n=15)based on different mucosal incision methods.Then compare the pathological data,clinical efficacy,surgical outcomes,and complications between the two groups.Results There were no statistically significant differences between the two groups in length of hospital stay,hospitalization costs,lesion diameter,lesion location and lesion nature(P＞0.05).The surgical time of the longitudinal group was significantly shorter than that of the circular group,and the difference was statistically significant(P＜0.05);There was no statistical significant in the incidence of intraoperative complications in the longitudinal group and the circular group(P＞0.05);The complete resection rate of the longitudinal group was lower than that of the circular group,but the difference was not statistically significant(P＞0.05).Conclusion ESD treatment for gastric submucosal tumors is safe and effective,and the longitudinal incision can shorten the surgical time compared to the circular incision.Both methods have the characteristics of low incidence of complications and high complete resection rate,and are worthy of clinical application.
