Objective To systematically review the efficacy and safety of azithromycin versus amoxicillin and clavulanate potassium in the treatment of otitis media in children.Methods PubMed,Embase,Cochrane Library,CNKI,WanFang Data and VIP databases were electronically searched to collect randomized controlled trials(RCTs)of azithromycin versus amoxicillin and clavulanate potassium in the treatment of otitis media in children from inception to February 28,2025.Two researchers independently screened the literature,extracted data,and assessed the risk of bias of the included studies.Meta-analysis was then performed using RevMan 5.3 software.Results A total of 21 RCTs involving 6,092 patients were included.The results of Meta-analysis showed that there was no statistically significant difference in the total effective rate after completion of treatment[RR=0.99,95％CI(0.96,1.03),P=0.72]and the total effective rate during follow-up period[RR=0.99,95％CI(0.94,1.04),P=0.10]between amoxicillin and clavulanate potassium group and azithromycin group.The results of subgroup analysis showed there was no statistically significant difference in the total effective rate between amoxicillin and clavulanate potassium group and azithromycin group in children under two years old or 2 years old and above(P＞0.05).The incidence of diarrhea[RR=0.41,95％CI(0.28,0.60),P＜0.001],vomiting[RR=0.49,95％CI(0.28,0.87),P=0.02],nausea[RR=0.46,95％CI(0.27,0.78),P=0.004],loose stools[RR=0.44,95％CI(0.24,0.79),P=0.006],rash[RR=0.62,95％CI(0.39,0.96),P=0.03],fungal dermatitis[RR=0.32,95％CI(0.18,0.57),P＜0.001],dermatitis[RR=0.31,95％CI(0.14,0.67),P=0.003]in the azithromycin group were all lower than those in the amoxicillin and clavulanate potassium group,and the difference was statistically significant.Conclusion The current evidence shows that azithromycin versus amoxicillin and clavulanate potassium are equally effective in treating otitis media in children,but azithromycin is considered safer.Due to the limited quality and quantity of included studies,more high-quality studies are required to verify the above conclusions.

Oropharyngeal squamous cell carcinoma(OPSCC)is a malignant tumor originating from the squamous epithelium of the oro-pharyngeal mucosa,accounting for more than 90％of oropharyngeal malignancies.In recent years,human papillomavirus(HPV)infec-tion has become one of the primary etiological factors of oropharyngeal squamous carcinoma.The incidence of HPV-associated oropharyn-geal squamous carcinoma has been rising annually,with a noticeable trend toward younger populations,posing a significant threat to hu-man health.Due to the distinct biological behavior and clinical characteristics of HPV-associated oropharyngeal squamous carcinoma com-pared to its non-HPV-related counterpart,the diagnostic and treatment strategies for oropharyngeal squamous carcinoma have undergone substantial changes.Prevention and screening for oropharyngeal squamous carcinoma are of critical importance.The diagnostic and treat-ment process involves multi-disciplinary collaboration,including oral and maxillofacial surgery,otolaryngology,head and neck surgery,oncology,radiology and pathology.Based on evidence from clinical practice,a comprehensive,integrated diagnostic and therapeutic ap-proach has been established,centered around the concept of"prevention,screening,diagnosis,treatment,and rehabilitation",covering the entire patient lifecycle and providing a valuable reference for clinical practice.

Objective:To investigate investigate repairing effect of adipose tissue-derived mesenchymal stem cell(ADSC)on fistula wounds in a rat model of fistula Crohn's disease(CD)and its regulation mechanism on miR-146a/interleukin-1 receptor-associ-ated kinase(IRAK)signaling axis.Methods:RT-PCR was used to detect the expression of miR-146a and mRNA expression of IRAK in the serum of 80 fistula-type CD patients treated with fistula after operation.Dual-luciferase gene reporter was used to analysis the re-lationship between miR-146a and IRAK.The rat CD successfully prepared fistula lesions and divided into control group(Con),ADSC intervention group(ADSC),ADSC+miR-146a-antagomir intervention group(ADSC+antagomir),ADSC+miR-146a-antagomir+siR-NA-IRAK intervention group(ADSC+antagomir+si),with 10 rats in each group.One hour after successful modeling,rats in ADSC group were injected with 2×106 cells/ml ADSC suspension into the area around the fistula,and subcutaneously injected 2 μg/kg of miR-146a-antagomir-NC.Rats in the ADSC+antagomir group were injected with 2×106 cells/ml ADSC suspension into the area around the fistula,and subcutaneously injected with 2 μg/kg of miR-146a-antagomir.Rats in the ADSC+antagomir+si group were injected with 2×106 cells/ml ADSC suspension into the area around the fistula,and subcutaneously injected with 2 μg/kg of miR-146a-an-tagomir+siRNA-IRAK.Rats in the Con group,were injected a dose of normal saline into the area around the fistula,and subcutaneous-ly injected 2 μg/kg of miR-146a-antagomir-NC.Each group was treated twice a day for 14 consecutive days.Flow cytometry was used to detect the apoptosis of fistula wound tissue in rats;kits were used to detect the contents of TNF-α and IL-6 in rats serum.Immuno-histochemistry was used to detect angiogenesis in the fistula wound tissue of the rats in each group.Western blot was used to detect the expressions of IRAK,apoptosis protein B-lymphoma-2(Bcl-2),Bcl-2-related x protein(Bax),vascular endothelial growth factor(VEGF)in fistula wound tissue.Results:The expression of miR-146a in the postoperative serum of patients with CD fistulae was sig-nificantly decreased,the mRNA expression of IRAK was significantly increased,and the differences were statistically significant(both P<0.05).miR-146a regulated the expression of IRAK.Compared with the Con group,the apoptosis rate,the contents of TNF-α and IL-6,the expressions of IRAK and Bax in the rat fistula wound of ADSC group,ADSC+antagomir group,ADSC+antagomir+si group were significantly decreased,the number of new blood vessels and the expression of Bcl-2 and VEGF in the fistula tissue were significantly increased.Compared with ADSC group,the apoptosis rate,the contents of TNF-α and IL-6,the expressions of IRAK and Bax in the rat fistula wound of ADSC+antagomir group,ADSC+antagomir+si group were significantly increased,the number of new blood vessels and the expressions of Bcl-2 and VEGF in the fistula tissue were significantly decreased.Compared with ADSC+an-tagomir group,the contents of TNF-α and IL-6,the expressions of IRAK and Bax in the rat fistula wound of ADSC+antagomir+si group were significantly decreased,the number of new blood vessels and the expressions of Bcl-2 and VEGF in the fistula tissue were significantly increased,and the differences were statistically significant(all P<0.05).Conclusion:ADSCs can significantly heal fistu-las after fistula lesions in CD model rats,which may be related to regulating the expression of miR-146a/IRAK,inhibiting cell apopto-sis,and promoting wound angiogenesis.

Objective To investigate and compare the epidemiological characteristics of common respiratory viruses among influenza-like illness(ILI)and severe acute respiratory infection(SARI)cases in Huzhou,Zhejiang Province before and after the COVID-19 pandemic,so as to provide a basis for formulating and adjusting the prevention and control strategies for viral respiratory infectious diseases.Methods ILI and SARI cases at two influenza surveillance sentinel hospitals in Huzhou and had throat swab samples collected during Nov 2017 to Feb 2020(pre-COVID-19 pandemic period)and Dec 2022 to Apr 2024(post-COVID-19 mitigation phase)were selected as the participants.Seven common viral respiratory pathogens were tested,including influenza A virus(H1N1 and H3N2 subtypes),influenza B virus(Victoria lineage,FluB),respiratory syncytial virus(RSV),rhinovirus(HRV),adenovirus(ADV),and severe acute respiratory syndrome coronavirus-2(SARS-CoV-2).The positive rates of respiratory pathogens before and after the COVID-19 pandemic were compared across different age groups and different time.Results A total of 7 948 ILI samples and 2 294 SARI samples were included.The overall positive rate of ILI samples increased from 33.6%to 47.1%,primarily due to the increase in influenza and COVID-19 infections;the overall positive rate of SARI samples decreased from 31.4%to 24.8%,mainly due to the reduction in HRV and ADV infections.During the post-COVID-19 mitigation phase,SARS-CoV-2(22.1%),H3N2(12.7%),and FluB(6.0%)were the primary pathogens in ILI samples,while RSV(7.1%),H3N2(5.3%),and HRV(4.5%)dominated in SARI samples.During the post-COVID-19 mitigation phase,the influenza virus circulation period was shortened.Before the COVID-19 pandemic,RSV was mainly detected in autumn and winter,while during the post-COVID-19 mitigation phase,out-of-season RSV epidemics were observed in spring and summer.Co-infection rate in ILI cases increased significantly in the post-COVID-19 mitigation phase,predominantly consisting of co-infections of COVID-19 and influenza A virus,while co-infection rate in SARI cases showed a decline.Conclusion We found important epidemiological changes in respiratory viruses in Huzhou during the post-COVID-19 mitigation phase compared to pre-COVID-19 period,including increased positive rates of influenza and COVID-19,and disruptions to the seasonal patterns of influenza and RSV.The prevention and control strategies should be adjusted in a timely manner based on the monitoring data.

Dopamine, as a catecholamine neurotransmitter widely distributed in the central nervous system, is involved in physiological functions such as motivation, arousal, reinforcement, and movement through various dopamine signaling pathways. The hippocampus receives dopaminergic neuron projections from regions such as the ventral tegmental area, locus coeruleus, and substantia nigra. Through D1-like and D2-like receptors, dopamine exerts significant regulatory effects such as spatial navigation, episodic memory, fear, anxiety, and reward. This review mainly summarizes the research progress on the functions of dopamine in the hippocampus from aspects including the sources of dopamine, receptor distribution and function, and the association of hippocampal dopamine system dysregulation with neurodegenerative diseases. The aim is to provide insights into the involvement of the dopamine system in hippocampal functions and the diagnosis and treatment of related diseases.

The tumor microenvironment is a crucial factor in tumor occurrence and progression. The hypoxic microenvironment is widely present in tumor tissue and is a key endogenous factor accelerating tumor deterioration. The "blood stasis toxin" theory, as an emerging perspective in tumor research, is regarded as the unique "soil" in tumor progression from the perspective of traditional Chinese medicine(TCM) due to its dynamic evolution mechanism, which closely resembles the formation of the hypoxic microenvironment. Scientifically integrating TCM theories with the biological characteristics of tumors and exploring precise syndrome differentiation and treatment strategies are key to achieving comprehensive tumor prevention and control. This article focused on the hypoxic microenvironment of the tumor, elucidating its formation mechanisms and evolutionary processes and carefully analyzing the internal relationship between the "blood stasis toxin" theory and the hypoxic microenvironment. Additionally, it explored the interaction among blood stasis, toxic pathogens, and hypoxic environment and proposed micro-level prevention and treatment strategies targeting the hypoxic microenvironment based on the "blood stasis toxin" theory, aiming to provide TCM-based theoretical support and therapeutic approaches for precise regulation of the hypoxic microenvironment.

The therapeutic effects of Yueju Pills on depression and cardiovascular diseases have been widely recognized. Previous studies have shown that the drug can significantly improve depressive-like behaviors induced by chronic unpredictable mild stress(CUMS) combined with atherosclerosis(AS). Given the complex pathogenesis of psychocardiac diseases, this study integrated metabolomics and network pharmacology to systematically elucidate the mechanism of Yueju Pills in alleviating depressive symptoms in psychocardiac diseases. The results demonstrate that, after Yueju Pill intervention, the levels of 9 abnormal metabolites in the hippocampus restore to normal ranges, primarily involving key pathways or signaling pathways, including the cyclic adenosine monophosphate(cAMP), mammalian target of rapamycin(mTOR), glycine/serine/threonine metabolism, and aminoacyl-tRNA biosynthesis. In a high-fat diet-induced CUMS ApoE~(-/-) mouse model, Yueju Pills significantly increases adenosine monophosphate(AMP) levels and decreases L-alanine and D-glyceric acid levels in the hippocampus. In conclusion, Yueju Pills exert antidepressant effects by regulating multiple metabolic axes, including glycine/serine/threonine metabolism and the cAMP, mTOR signaling pathways. Network pharmacology predictions reveal that the treatment of CUMS combined with AS by its core active components may be realized through modulating pathways concerning neuroinflammation and synaptic plasticity, including serine/threonine-protein kinase 1(AKT1), mitogen-activated protein kinase 1(MAPK1), and prostaglandin-endoperoxide synthase 2(PTGS2). This study provides a theoretical reference for the clinical application of Yueju Pills in alleviating the depressive symptoms of psychocardiac diseases.
