The homeostasis of the oral microbiome is essential for maintaining host health, and its disruption can contribute to the development of both oral and systemic diseases. The oral microbiome influences the initiation and progression of oral squamous cell carcinoma (OSCC) through multiple mechanisms. ① Oral microbes can directly act on epithelial cells, inducing cell-cycle dysregulation, DNA damage, and epigenetic reprogramming, thereby promoting cell proliferation and epithelial-mesenchymal transition (EMT). For example, Fusobacterium nucleatum binds to E-cadherin via its adhesin FadA, activating the β-catenin pathway and directly driving tumor-cell proliferation and EMT, while Porphyromonas gingivalis reprograms lipid synthesis to enhance the stemness of OSCC cells. ② Oral microbes and their metabolites reshape the tumor immune-suppressive microenvironment by altering the density, composition, and function of infiltrating immune cells. Periodontal pathogens induce a chronic inflammatory state in the oral cavity and activate signaling cascades such as MAPK/ERK and NF-κB, thereby indirectly accelerating OSCC progression. ③ Bacteria and viruses in the oral cavity exhibit synergistic interactions. Bacterial biofilms and proteases facilitate viral activation and infection, and microbial metabolites such as butyrate can enhance histone acetylation to promote the lytic reactivation of latent viruses. ④ At the ecological level, the depletion of commensals and expansion of anaerobic pathogens disrupt the metabolic network of the community, and complex interspecies interactions collectively shape a pro-carcinogenic niche that drives OSCC progression on multiple fronts. Future studies should integrate multi-omics analyses with longitudinal clinical cohorts to explore functional causal networks of key microbial communities and develop individualized targeted intervention strategies for microecology.

OBJECTIVE To analyze the efficacy and safety of luspatercept in the treatment of myelodysplastic syndromes (MDS) anemia, and provide reference for clinical medication. METHODS The literature related to luspatercept for MDS anemia in PubMed, Cochrane Library, Embase and Web of Science were searched by computer, and the search time was from the establishment of the database to January 2024. The quality of literature was evaluated after they were screened according to inclusion and exclusion criteria, the single-group rate meta-analysis and sensitivity analysis were performed by using RevMan 5.4 software, and the subgroup analysis was conducted. RESULTS A total of 756 patients in 9 articles were included in this study. The results of meta-analysis showed that the proportion of MDS patients who reached ≥8 weeks of red blood cell transfusion independence (RBC-TI) was 46% after using luspatercept [95%CI (0.28, 0.64), P<0.000 01]. The proportion of MDS patients whose hematological improvement in erythrocyte (HI-E) was 59% [95%CI (0.43, 0.74), P<0.000 01]. Among them, 5 articles reported that the proportion of MDS patients with grade 3-4 adverse reactions was 14% [95%CI (0.07, 0.22), P=0.000 2], and the poor general condition, infection, blood and lymphatic system disease were the common adverse reactions. Subgroup analysis showed that the source of heterogeneity was the blood transfusion burden in the proportion of MDS patients with RBC-TI≥8 weeks, and the source of heterogeneity was the 0931-8356251。revised international prognostic scoring system (IPSS-R) risk grade, SF3B1 mutation status and blood transfusion burden in the proportion of MDS patients with HI-E. Sensitivity analysis showed that the results of this study were stable. CONCLUSIONS Luspatercept can significantly improve blood transfusion dependence, reduce blood transfusion burden and promote hematology improvement in MDS patients. But attention should be paid to the occurrence of grade 3-4 adverse events; adverse events such as poor general condition, infection, blood and lymphatic system diseases are more common.

The areas of S. japonicum-infected snail habitats appeared an average annual reduction of 47.09% in Wuhan City from 2005 to 2023 [AAPC = -47.09%, 95% CI: (-52.92%, -38.26%), P < 0.01], with two joinpoints in 2011 and 2014, respectively, and the tendency towards a decline showed statistical significance during the period from 2011 through 2014 [APC = -97.27%, 95% CI: (-98.65%, -88.06%), P < 0.01]. The areas of snail habitats in inner embankments appeared an average annual reduction of 4.45% in Wuhan City from 2005 to 2023 [AAPC = -4.45%, 95% CI: (-5.18%, -3.82%), P < 0.01], with three joinpoints in 2011, 2015 and 2018, respectively, and statistical significance was seen in the tendency towards a decline during the period from 2005 through 2011 [APC = -16.38%, 95% CI: (-20.15%, -14.25%), P < 0.01]. In addition, the actual areas of snail habitats appeared an average annual reduction of 2.65% in Wuhan City from 2005 to 2023 [AAPC = -2.65%, 95% CI: (-2.89%, -2.40%), P < 0.01], with a joinpoint in 2013, and the tendency towards a decline showed statistical significance during the period from 2013 through 2023 [APC = -4.06%, 95% CI: (-4.66%, -3.58%), P < 0.01]. Conclusions The integrated schistosomiasis control programme achieved significant effectiveness in Wuhan City from 2005 to 2023, with a tendency towards a decline in morbidity due to schistosomiasis in humans and livestock and snail status. The integrated schistosomiasis control strategy with emphasis on management of the source of S. japonicum infections should continue to be implemented to consolidate the schistosomiasis control achievements and achieve the goal of schistosomiasis elimination in the city.

Objective To investigate the impact of nucleophosmin 1-mutated(NPM1m)subtypes,variant allele frequency(VAF)and co-mutations on the survival outcomes of patients with acute myeloid leukemia(AML).Methods Clinical data,mutation status,and outcomes of 86 NPM1m-AML patients admitted in Department of Hematology,First Hospital of Lanzhou University between June 2017 and September 2024 were collected and retrospectively analyzed.Spearman correlation analysis,Kaplan-Meier curve analysis,Log-rank test,and Cox regression analysis was applied for correlation analysis,survival analysis,and factors affecting survival.Results The overall survival(OS)was significantly shorter in the Rares subtype of NPM1m than the ABD subtype(median OS:164 d vs 416 d,P=0.043).The VAF of NPM1m was positively correlated with the initial peripheral blood white blood cell count and lactate dehydrogenase(LDH)level(P<0.05).OS was reduced when VAF was≥0.37(median OS:164 d vs 730 d,P=0.003).The presence of myelodysplasia-related gene(MR)mutations was associated with a poorer prognosis when compared to the MR wild-type(median OS:45 d vs 395 d,P<0.001).The triple mutation of FMS-like tyrosine kinase 3-internal tandem duplication(FLT3-ITD)and DNMT3A also indicated a worse prognosis than the non-triple mutation(median OS:173 d vs 483 d,P=0.007).The presence of PTPN11 mutations was associated with improved OS(median OS:395 d vs 240 d,P=0.027),while the patients with coexistence of N/KRAS mutations trended toward better prognosis than the wild-type patients(median OS:662 d vs 189 d)though no statistical significance(P=0.070).Multivariate analysis revealed that LDH(HR=1.002,95%CI:1.000~1.003,P=0.005),NPM1m VAF(HR=2.415,95%CI:1.208~4.829,P=0.013),Rares subtype(HR=3.037,95%CI:1.134~8.136,P=0.027),and MR mutations(HR=5.283,95%CI:1.991~14.017,P<0.001)were independent risk factors associated with OS in the patients.Conclusion Molecular heterogeneity of NPM1m should be taken into account in prognostic stratification of NPM1m-AML.Factors including the Rares subtype,VAF≥0.37,coexistence of FLT3-ITD and DNMT3A mutations,and MR mutations are associated with poor prognosis of NPM1m-AML.The presence of PTPN11 mutations improves the prognosis,while the presence of N/KRAS mutations shows a trend toward better prognosis.LDH,NPM1m VAF,Rares subtype,and MR mutations are independent risk factors affecting OS of patients with NPM1m-AML.

The development of medical research is completed by the cooperation of sponsors, investigators, subjects, and ethics committees. Clinically, it mainly includes clinical trials of medical devices, clinical medicine and new technology research. This paper analyzed the game and the relationship between rights, responsibilities and interests of relevant parties in medical research, combined with the relevant costs and sharing principles involved in medical research, and found that the use of the word "free" in the informed consent is easy to cause misunderstanding and the lack of relevant compensation costs in the informed consent, while the compensation and insurance costs had some problems, such as the imperfect subject compensation mechanism and the insufficient insurance purchase by the sponsor, which can not protect the basic rights and interests of the subjects. Therefore, in order to standardize the cost management of clinical medical research, it is necessary to standardize the process and content of informed consent, strengthen the supervision of medical research process, establish medical research damage compensation fund and research damage insurance system, so as to better protect the rights and interests of subjects.

Objective To analyze the trends in Oncomelania hupensis distribution in Wuhan City, Hubei Province from 2003 to 2022, so as to provide insights into precision schistosomiasis control. Methods Data pertaining to O. hupensis snail survey in Wuhan City from 2003 to 2022 were collected. The trends in the proportion of areas with snail habitats, actual area with snail habitats, mean density of living snails and prevalence of Schistosoma japonicum infection in snails were evaluated in schistosomiasis-endemic areas of Wuhan City from 2003 to 2022 with the slope of trend curve (β), annual percent change (APC) and average annual percent change (AAPC) using a Joinpoint regression model. Results During the period from 2003 through 2022, there were two turning points for the proportion of areas with snail habitats in Wuhan City in 2005 and 2015, with a rise during the period from 2003 to 2005 (β1 = 5.93, t = 1.280, P > 0.05), a decline from 2005 to 2015 (β2 = −0.88, t = −2.074, P > 0.05) and a rise from 2015 to 2022 (β3 = 1.46, t = −2.356, P < 0.05). During the period from 2003 through 2022, there were two turning points for the proportion of areas with snail habitats in islet endemic areas of Wuhan City in 2006 and 2015, with no significant differences in the trends from 2003 to 2006 (β1 = 4.64, t = 1.888, P > 0.05) or from 2006 to 2015 (β2 = −1.45, t = −2.143, P > 0.05), and with a tendency towards a rise from 2015 to 2022 (β3 = 2.04, t = −3.100, P < 0.05). During the period from 2003 through 2022, there were two turning points for the proportion of areas with snail habitats in inner embankment endemic areas of Wuhan City in 2012 and 2020, with a tendency towards a decline from 2003 to 2012 (β1 = −0.39, t = −4.608, P < 0.05) and with no significant differences in the trends from 2012 to 2020 (β2 = 0.03, t = 0.245, P > 0.05) and from 2020 to 2022 (β3 = 1.38, t = 1.479, P > 0.05). During the period from 2003 to 2022, the actual area with snail habitats all appeared a tendency towards a decline in Wuhan City, and in islet and inner embankment endemic areas of Wuhan City from 2003 to 2022 (AAPC = −2.39%, −5.75% and −2.35%, all P values < 0.05). The mean density of living snails reduced from 0.087 snails/0.1 m2 in 2003 to 0.027 snails/0.1 m2 in 2022 in Wuhan City, with a significant difference in the tendency towards the decline (APC = AAPC = −11.47%, P < 0.05). The annual mean decline rate of the mean density of living snails was 17.36% in outside embankment endemic areas of Wuhan City from 2003 to 2022 (APC = AAPC = −17.36%, P < 0.05), and there was no significant difference in the trends in the mean density of living snails in islet endemic areas of Wuhan City from 2003 to 2022 (APC = AAPC = −0.97%, P > 0.05). In addition, the prevalence of S. japonicum infection in snails appeared a tendency towards a decline in Wuhan City from 2003 to 2022 (APC = AAPC = −12.45%, P < 0.05). Conclusions The proportion of areas with snail habitats, actual area with snail habitats, mean density of living snails and prevalence of S. japonicum infection in snails all appeared a tendency towards a decline in Wuhan City from 2003 to 2022. Intensified snail control, modification of snail habitats, shrinking of areas with snails and implementation of grazing prohibition in snail-infested settings are required, in order to facilitate the progress towards schistosomiasis elimination in Wuhan City.

Objective:To analyze the molecular evolutional characteristics of the hemagglutinin and neuraminidase genes of influenza A (H3N2) viruses isolated in Yancheng from 2022 to 2024.Methods:The throat swab specimens of influenza-like illness ( ILI) from sentinel surveillance hospital and outbreak sites were detected using the method of real time Rt-qPCR. The influenza A(H3N2) viruses were isolated using MDCK cells culture method from April 2022 to Marh 2024. The strains isolated from 2022 to 2024 were selected randomly and their sequences of the HA1 and NA genes were amplified through one step RT-PCR method and the PCR products were sequenced.The nucleotide and amino acid site variations and evolutionary characteristics of the genes were analyzed using relevant bioinformatics software. The mutations of genes and nucleic acid locus were analyzed and the evolutional trees were generated using bioinformatics software.Results:A total of 5 020 samples were collected between April 2022 and March 2024, the positive detection rate of influenza virus nucleic acid was 18.59%(933/5 020).The winter and spring influenza peaks were obvious in the two monitoring seasons from April 2022 to March 2024. Among them, the summer influenza peak was obvious in the monitoring season from April 2022 to March 2023, and the H3N2 subtype influenza virus was the dominant epidemic strain in the two monitoring seasons. Genetic evolution tree displayed: the clustering relationships of the respective branches of HA1 and NA genes of 32 strains isolated in Yancheng were basically the same.The HA1 and NA genes of 24 strains isolated from 2023-2024 in Yancheng and the 2022-2024 Northern Hemisphere vaccine strain A/Darwin/9/2021 (H3N2) were located in the 3C.2a1b2a.2a.3a.1 evolutionary lineage, while the 8 strains isolated in the 2022 in Yancheng and the 2021-2022 Northern Hemisphere vaccine strain A/Cambodia/e0826360/2020 (H3N2) were located in the 3C.2a1b.2a.1a evolutionary lineage.The 6 strains (A/JSTH/11735/2023, A/JSTH/11788/2023, A/JSTH/11974/2023, A/JSYD/353/2023, A/JSYD/354/2023, A/JSTH/138/2023) all exhibited variations in the F79L, N122D, P239S, and K276E amino acid sites, which were present in both sporadic and outbreak strains. Because the strains of the antigen epitopes, receptor binding sites and glycosylation sites in the HA1 genes had a certain degree of variations in Yancheng in the 2022-2024 year, the immunogenicity matching between the 24 strains isolated in the 2023-2024 and the Northern Hemisphere vaccine strain A/Darwin/9/2021 was good, while the immunogenicity matching between the 8 strains isolated in the 2022 and the Northern Hemisphere vaccine strain A/Cambodia/e0826360/2022 was good; 32 strains isolated from 2022 to 2024 had no mutations in catalytic residues and drug resistant sites of NA genes.Conclusion:These result indicated that the HA1 and NA genes of influenza A/H3N2 viruses circulated in Yancheng city from 2022 to 2024 are changed gradually.The accumulation of these mutations would result in antigenic drift of influenza A(H3N2) viruses and increase the mismatching of the recommended vaccine strain.Compared with the vaccine strain A/Darwin/9/2021(H3N2), the strains isolated in the 2022 had substantially result in antigenic drift on the whole.The influenza A(H3N2) viruses surveillance should be strengthened to find the new mutant of virus in time.
