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.

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.

Objective:The objective of this study is to analyze the detection rate, the pathogenic fungus distribution, risk factors and drug sensitivity of fungal infection of external auditory canal in patients diagnosed with chronic otitis media. Methods:The data of a total of 419 patients with chronic suppurative otitis media or middle ear cholesteatoma who were admitted from January 2019 to February 2023 were retrospectively analyzed. Results:A total of 419 patients were included, and 71 patients（16.9%） were positive for fungal culture. The disease mostly occurred in subjects aged 51-60 years old, and patients over 60 years old（47 cases, 66.2%）. From the fungal culture of external auditory canal secretions, 48 cases（11.4%） of Aspergillus and 14 cases（3.3%） of Candida were identified. The prevalence of fungal cultures in patients with chronic suppurative otitis media（20.8%） was significantly higher than that in patients with middle ear cholectestoma（4.9%）. The detection rate of Fungal was significantly increased after topical treatment with antibiotic ear drops（47.0% vs 13.6%）. Most of the isolated fungal strains are wild-type, and they are the sensitivity to voriconazole and fluconazole was the highest（97.2%）. For patients with positive fungal culture, iodoform gauze with triamcinolone acetonide and econazole cream was used to fill the external auditory canal during surgery. There was no significant difference in the tympanic membrane healing rate between patients with positive fungal culture and patients with negative fungal culture at 3 weeks after surgery（98.6% vs 97.7%）. Conclusion:Fungal infections of external auditory canal in patients with chronic otitis media tend to occur in older patients, which is more common in patients with chronic suppurative otitis media. Long-term topical treatment with antibiotic ear drops is an independent risk factor for fungal infection of external auditory canal in patients with chronic otitis media. The isolated fungal strains were highly sensitive to antifungal drugs. Therefore, it is advisable to refrain from employing topical antibiotic treatment for elderly patients with chronic suppurative otitis media/middle ear cholesteatoma, abuse of local antibiotic therapy should be avoided, and Fungal-related pathogenic examinations should be actively performed and anti-fungal drugs should be added if necessary.

Obesity is a significant risk factor for cancer and is associated with breast cancer metastasis. Nevertheless, the mechanism by which alterations in systemic metabolism affect tumor microenvironment (TME) and consequently influence tumor metastasis remains inadequately understood. Herein, we found that perturbations in circulating metabolites induced by obesity promote metastasis-like phenotypes in breast cancer. Oleoylcarnitine (OLCarn) concentrations were elevated in the serum of obese mice and humans. Administration of exogenous OLCarn induces metastasis-like characteristics in breast cancer cells. Mechanistically, OLCarn directly interacts with the Arg176 site of adenylate cyclase 10 (ADCY10), leading to the activation of ADCY10 and enhancement of cAMP production. Mutations at Arg176 prevent OLCarn from binding to ADCY10, disrupting the ADCY10-mediated activation of cyclic adenosine monophosphate (cAMP) signaling pathway. This activation promotes transcription factor 4 (TCF4)-dependent kinesin family member C1 (KIFC1) transcription, thereby driving breast cancer metastasis. Conversely, the neutralization of both ADCY10 and KIFC1 through knockdown or pharmacological inhibition abrogates the oncogenic effects mediated by OLCarn. Hence, obesity-induced systemic environmental changes lead to the aberrant accumulation of OLCarn within the TME, making it a potential therapeutic target and biomarker for breast cancer.

Objective: To investigate the effects of paeoniflorin (Pae) on acute kidney injury ( AKI) and mouse renal tubular epithelial cell ( mRTEC) damage induced by lansoprazole (LPZ) and cisplatin (CIS) through in vivo and in vitro experiments . Methods : The C57BL/6J mice or mRTECs were divided into four groups : normal control (NC) group , NC + LPZ group , CIS group , and CIS + LPZ group . Serum creatinine (CRE) and blood urea nitro- gen (BUN) levels in mice were measured , and kidney pathology was observed with HE staining. Western blot , im- munohistochemistry , and immunofluorescence were used to detect the expression levels of kidney injury molecule-1 (KIM-1) and receptor-interacting protein kinase (RIPK) 1 , RIPK3 , and mixed lineage kinase domain-like protein (MLKL) . Subsequently , C57BL/6J mice or mRTECs were divided into six groups : NC group , NC + Pae group , CIS + LPZ (M) group , and CIS + LPZ + Pae ( M + Pae) group . Serum CRE and BUN levels in each group were measured , kidney pathology was observed with HE staining , and ultrastructural changes in the kidney were observed with transmission electron microscopy. The KIM-1 and necroptosis-related protein expression levels were detected by Western blot , immunohistochemistry , and immunofluorescence . Results: Compared with the NC group , CRE and BUN levels were elevated in the CIS group , and these levels were further increased after LPZ in- tervention (all P < 0. 001) . Compared with the CIS group , renal tubular dilation and brush border loss were evi- dent in the CIS + LPZ group based on HE staining of kidney tissue (P < 0. 001) . Compared with the NC group , the expression levels of KIM-1 , RIPK1 , RIPK3 , and MLKL in the renal tissues of mice in the CIS group increased ( all P < 0. 001) , and compared with the CIS group , The expression levels of KIM-1 , RIPK1 , RIPK3 and MLKL in the renal tissues of mice in the CIS + LPZ group increased (all P < 0. 001) . After Pae treatment , compared with group M , the expression levels of CRE , BUN , KIM-1 , RIPK1 , RIPK3 and MLKL in each group of mice decreased significantly and in a dose-dependent manner (all P < 0. 001) . Conclusion LPZ promotes CIS-induced AKI by enhancing necroptosis in renal tubular epithelial cells , and Pae can improve CIS and LPZ-induced AKI by inhibi- ting necroptosis .

Objective:To report the results of national surveillance on the distribution and antimicrobial resistance profile of clinical Gram-negative bacteria isolates from bloodstream infections in China in 2022.Methods:The clinical isolates of Gram-negative bacteria from blood cultures in member hospitals of national bloodstream infection Bacterial Resistant Investigation Collaborative System（BRICS）were collected during January 2022 to December 2022. Antibiotic susceptibility tests were conducted by agar dilution or broth dilution methods recommended by Clinical and Laboratory Standards Institute（CLSI）. WHONET 5.6 and SPSS 25.0 software were used to analyze the data.Results:During the study period，9 035 strains of Gram-negative bacteria were collected from 51 hospitals，of which 7 895（87.4%）were Enterobacteriaceae and 1 140（12.6%）were non-fermenting bacteria. The top 5 bacterial species were Escherichia coli（ n=4 510，49.9%）， Klebsiella pneumoniae（ n=2 340，25.9%）， Pseudomonas aeruginosa（ n=534，5.9%）， Acinetobacter baumannii complex（ n=405，4.5%）and Enterobacter cloacae（ n=327，3.6%）. The ESBLs-producing rates in Escherichia coli， Klebsiella pneumoniae and Proteus spp. were 47.1%（2 095/4 452），21.0%（427/2 033）and 41.1%（58/141），respectively. The prevalence of carbapenem-resistant Escherichia coli（CREC）and carbapenem-resistant Klebsiella pneumoniae（CRKP）were 1.3%（58/4 510）and 13.1%（307/2 340）；62.1%（36/58）and 9.8%（30/307）of CREC and CRKP were resistant to ceftazidime/avibactam combination，respectively. The prevalence of carbapenem-resistant Acinetobacter baumannii（CRAB）complex was 59.5%（241/405），while less than 5% of Acinetobacter baumannii complex was resistant to tigecycline and polymyxin B. The prevalence of carbapenem-resistant Pseudomonas aeruginosa（CRPA）was 18.4%（98/534）. There were differences in the composition ratio of Gram-negative bacteria in bloodstream infections and the prevalence of main Gram-negative bacteria resistance among different regions，with statistically significant differences in the prevalence of CRKP and CRPA（ χ2=20.489 and 20.252， P<0.001）. The prevalence of CREC，CRKP，CRPA，CRAB，ESBLs-producing Escherichia coli and Klebsiella pneumoniae were higher in provinicial hospitals than those in municipal hospitals（ χ2=11.953，81.183，10.404，5.915，12.415 and 6.459， P<0.01 or <0.05），while the prevalence of CRPA was higher in economically developed regions（per capita GDP ≥ 92 059 Yuan）than that in economically less-developed regions（per capita GDP <92 059 Yuan）（ χ2=6.240， P=0.012）. Conclusions:The proportion of Gram-negative bacteria in bloodstream infections shows an increasing trend，and Escherichia coli is ranked in the top，while the trend of CRKP decreases continuously with time. Decreasing trends are noted in ESBLs-producing Escherichia coli and Klebsiella pneumoniae. Low prevalence of carbapenem resistance in Escherichia coli and high prevalence in CRAB complex have been observed. The composition ratio and antibacterial spectrum of bloodstream infections in different regions of China are slightly different，and the proportion of main drug resistant bacteria in provincial hospitals is higher than those in municipal hospitals.
