Homing pigeons and many other animals have exquisite geomagnetic sensing ability and can accurately find appropriate paths and directions during long-distance migration.Homing pigeons are the preferred animal model for studies of biological geomagnetic navigation.Despite substantial progress in research on bio-geomagnetic navigation over the past few decades,the biological mechanism is still unclear.In this paper,we review recent advancements in research on biological magnetoreception using homing pigeons.We focus on the magnetic sensing mechanisms of the magnetoreceptor models based on nanoscale ferromagnetic particles and the light-dependent radical pair model.Key directions for biological magnetoreception research are proposed.This review provides an improved theoretical basis for the study of geomagnetic navigation using homing pigeons as well as insight into the operating principles of the biological magnetic perception system.

This study investigated the prevalence of canine ticks and the types of their carried pathogens in select cities of Liaon-ing Province,to provide a theoretical scientific basis for the prevention and control of ticks and tick-borne diseases.Canine ticks were collected from six cities in Liaoning Province(Shenyang,Dalian,Anshan,Chaoyang,Tieling,Dandong)and identified through a combination of morphological and molecular biology methods.PCR was used to detect five tick pathogens:Rickettsia,Borrelia burgdor-feri,Babesia,Pseudomonas aeruginosa,and Ehrlichia.Canine ticks were prevalent primarily in Liaoning Province from April to June.The collected ticks included 456 Haemaphysalis longicornis,70 Ixodes persulcatus,and 31 Rhicephalus sanguineus.Three tick borne pathogens,Ehrlichia,Borrelia burgdorferi,and Rickettsia,were detected,whereas no Babesia or Pseudomonas were detected.The to-tal detection rate of Ehrlichia(46.85%),which is significant difference with total detection rate of Borrelia burgdorferi(10.81%)(χ2=33.392,P<0.05),but insignificant difference with total detection rate of Rickettsia(34.23%)(χ2=3.370,P>0.05),Both Eh-rlichia and Rickettsia were distributed in the six cities.Haemaphysalis longicornis was the dominant tick species parasite on the surfaces of dogs in Liaoning Province.The main tick borne pathogens in dogs in Liaoning Province were Ehrlichia and Rickettsia.

Objective·To analyze the clinicopathologic characteristics,gene mutation profile,and prognostic factors of patients with adrenal diffuse large B-cell lymphoma(DLBCL).Methods·From March 2002 to December 2022,a total of 105 patients with adrenal DLBCL admitted to Ruijin Hospital,Shanghai Jiao Tong University School of Medicine were retrospectively analyzed for their clinicopathological data,survival outcomes,and prognostic factors.Patients'gene mutation profiles were evaluated by targeted sequencing of 152 lymphoma-related genes.Results·The median age of the patients was 62(15?82)years and the male-to-female ratio was 2.3∶1.Among them,63 patients(60.0%)were over 60 years old,22 patients(21.0%)had an Eastern Cooperative Oncology Group(ECOG)performance status of two or higher,87 patients(82.9%)were staged Ann Arbor Ⅲ?Ⅳ,92 patients(87.6%)had elevated serum lactate dehydrogenase(LDH)levels(above the upper limit of reference),84 patients(80.0%)had extranodal invasion in at least two organs,67 patients(63.8%)were of non-germinal center B-cell(non-GCB)origin,and 95 patients(90.5%)had an international prognosis index(IPI)scored over 2.With a median follow-up of 28.3(0.7?191.9)months,the estimated 2-year overall survival(OS)rate and progression-free survival(PFS)rate were 68.3%and 53.1%,respectively.The estimated 5-year OS rate and PFS rate were 52.6%and 44.0%,respectively.Among 93 patients who could be evaluated for clinical outcomes,62(66.7%)got a complete response(CR).Univariate analysis and multivariate Cox analysis revealed that age over 60 years was an adverse prognostic factor for PFS,and ECOG performance status of two or higher was an adverse prognostic factor for both OS and PFS.Targeted gene sequencing in 46 adrenal diffuse DLBCL patients showed high mutation frequencies in lysine methyltransferase 2D(KMT2D;n=17,37%),Pim-1 proto-oncogene,serine/threonine kinase(PIM1;n=17,37%),MYD88 innate immune signal transduction adaptor(MYD88;n=15,33%),CD79b molecule(CD79B;n=13,28%),and BTG anti-proliferation factor 2(BTG2;n=10,22%).Conclusion·Age over 60 years is an adverse prognostic factor for PFS,and ECOG performance status of two or higher is an adverse prognostic factor for both OS and PFS in patients with adrenal DLBCL.Patients exhibited high frequencies of KMT2D,PIM1,MYD88,CD79B,and BTG2 mutations,as well as an increased proportion of the MCD-like subtype.

Objective·To investigate the clinicopathologic features,gene mutation profile,and real-world survival prognosis of diffuse large B-cell lymphoma(DLBCL)with pulmonary involvement.Methods·The clinical data of 110 patients with newly diagnosed,pathologically confirmed DLBCL and pulmonary involvement at Ruijin Hospital,Shanghai Jiao Tong University School of Medicine,between August 2003 and December 2022 were retrospectively collected and analyzed.Evaluation of the efficacy of treatment,survival analyses,and univariate and multivariate analyses were performed in 88 patients who received a first-line regimen based on rituximab in combination with cyclophosphamide,doxorubicin/epirubicine,vincristine,and prednisone(R-CHOP).A total of 74 patients underwent targeted DNA sequencing of 55 lymphoma-related genes and were evaluated for mutations.Results·Among the 110 patients,72(65.5%)were>60 years old,52(47.3%)were female,92(83.6%)presented with Ann Arbor stage Ⅲ?Ⅳ,20(18.2%)had ECOG scores≥2,75(68.2%)had elevated lactate dehydrogenase(LDH)levels,79(71.8%)had≥2 extranodal involvements,32(31.4%)were classified as germinal center B-cell subtype,22(26.8%)were diagnosed with double expressor lymphoma,and 4(4.6%)with double-hit lymphoma.Among the patients treated with R-CHOP-based first-line regimens,the objective response rate(ORR)was 68.2%,the 5-year progression-free survival(PFS)rate was 43.7%,and the 5-year overall survival(OS)rate was 65.4%.Univariate analysis showed that elevated LDH and ECOG score≥2 were poor prognostic factors for PFS and OS,and mutations in PIM1 and CD79B were poor prognostic factors for PFS among high-frequency mutations.Multivariate analysis showed that elevated LDH was an independent adverse prognostic factor for PFS(HR=2.47,95%CI 1.28?4.77)and OS(HR=2.71,95%CI 1.21 ? 6.07).Targeted sequencing results showed that PIM1(25.7%),MYD88(24.3%),TP53(18.9%),CD79B(17.6%),KMT2D(17.6%),and TNFAIP3(16.2%)were the high-frequency mutations with mutation rates over 15%.Conclusion·Elevated LDH is an independent adverse prognostic factor for PFS and OS in DLBCL with pulmonary involvement.Mutations in PIM1,MYD88,TP53,CD79B,KMT2D,and TNFAIP3 are frequently observed in this population.

Objective To explore the characteristics and prognosis of follicular lymphoma(FL)with bulky disease under rituximab-based first-line treatment.Methods A retrospective analysis was conducted on 525 FL patients diagnosed between September 2009 and September 2021 who received rituximab as a first-line treat-ment[342 patients received rituximab combined with chemotherapy(R-chemo),183 patients received rituximab plus lenalidomide(R2)].The clinicopathologic characteristics,gene mutations,and prognosis of bulky FL patients were analyzed.Results Compared to non-bulky FL patients,bulky FL patients had a significantly higher proportion of lymph node≥5 sites,≥2 extranodal involvement,bone marrow involvement,elevated LDH,and a higher proportion in the high-risk group of FLIPI1 and FLIPI2.Gene sequencing revealed a significantly higher mutation rate of ZNF608 in bulky FL patients compared to non-bulky FL patients.In patients receiving R-chemo as the first-line treatment,there was no significant difference in progression-free survival(PFS)and overall survival(OS)between bulky and non-bulky FL patients.However,in patients treated with R2,the PFS and OS of bulky FL patients was significantly shorter.Conclusions Bulky FL patients compared to non-bulky FL patients have a significantly higher proportion of high-risk baseline characteristics.For bulky FL at diagnosis,chemo-free regimens require further exploration on the basis of R2.

ObjectiveBased on transcriptomics， to explore the mechanism of Hei Xiaoyaosan regulating the phosphatidylinositol 3-kinase/protein kinase B （PI3K/Akt） signaling pathway to improve the learning and memory ability of insomnia rats with liver depression syndrome. MethodsSixty 8-week-old male SD rats were randomly divided into the blank group， model group， eszopiclone group （0.09 mg·kg^-1）， and low， medium， and high dose groups of Hei Xiaoyaosan （3.82， 7.65， 15.30 g·kg^-1）， with ten rats in each group. Except for the blank group， the other groups were induced insomnia rat model with liver depression by chronic restraint， tail clamping stimulation and intraperitoneal injection of p-chlorophenylalanine （PCPA）. Each treatment group received intragastric administration according to the specified dosage， once a day for 14 consecutive days. The pentobarbital sodium cooperative sleep test， open field test， and Morris water maze test were used to test the sleep quality， depressive-like behavior， and learning and memory abilities of rats. Additionally， enzyme-linked immunosorbent assay （ELISA） was used to detect the contents of 5-hydroxytryptamine （5-HT）， γ-aminobutyric acid （GABA）， brain-derived neurotrophic factor （BDNF）， glial cell line-derived neurotrophic factor （GDNF） and nitric oxide （NO） in hippocampus. Hematoxylin-eosin （HE） staining was performed to observe pathological changes of the hippocampal tissue， while terminal deoxynucleotidyl transferase deoxyuridine triphosphate （dUTP） nick end labeling （TUNEL） was used to evaluate apoptosis of hippocampal neurons. Transcriptomic sequencing technology was employed to identify differentially expressed genes in hippocampus between the model group and the blank group， as well as between the medium-dose group of Hei Xiaoyaosan and the model group. Gene Ontology （GO） and Kyoto Encyclopedia of Genes and Genomes （KEGG） enrichment analysis were performed on the intersecting genes. Subsequently， the enriched key genes and signaling pathways were analyzed and verified. Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR） was utilized to assess the mRNA expression levels of phosphatase and tensin homolog （PTEN）， B-cell lymphoma-2 （Bcl-2）-like protein 11 （BCL2L11）， and mitogen-activated protein kinase 1 （MAPK1） in hippocampus， and Western blot was employed to evaluate the protein expressions of PI3K， phosphorylation （p）-PI3K， Akt， p-Akt， Bcl-2， Bcl-2-associated X protein （Bax）， and cleaved Caspase-3 in the same tissue. ResultsCompared with the blank group， the model group exhibited a reduction in body weight， an increase in sleep latency， and a decrease in sleep duration （P<0.01）. Additionally， rats showed obvious depression-like behavior， and their learning and memory abilities decreased. Furthermore， the contents of 5-HT， GABA， NO， BDNF and GDNF in hippocampus decreased （P<0.01）. Histological examination revealed a disorganized cell arrangement in the CA1 region of the hippocampus， characterized by irregular cell shapes， a reduced cell count， deeply stained and pyknotic nuclei， increased vacuolar degeneration， and an elevated apoptosis rate （P<0.01）. Compared with the model group， the body weight of the high and medium dose groups of Hei Xiaoyaosan increased， the sleep latency shortened and the sleep time prolonged （P<0.05， P<0.01）. Additionally， depression-like behavior and learning and memory abilities of rats were significantly improved， the levels of 5-HT， GABA， NO， BDNF and GDNF in the hippocampus increased （P<0.05， P<0.01）. These interventions also ameliorated pathological damage in the hippocampal CA1 area and reduced the apoptosis of hippocampal neurons （P<0.01）. Transcriptomic sequencing results indicated that Hei Xiaoyaosan might exert a therapeutic effect by regulating PI3K/Akt pathway through key mRNAs such as PTEN， BCL2L11， and MAPK1. The roles of these key mRNAs and proteins within PI3K/Akt pathway were further validated. In comparison to the blank group， the expression levels of PTEN， BCL2L11 and MAPK1 mRNA in the hippocampus of rats in the model group were increased （P<0.01）， while the protein expression levels of p-PI3K， p-Akt and Bcl-2 were decreased （P<0.01）， and the protein expression levels of PTEN， Bax and cleaved Caspase-3 were increased （P<0.01）. Compared with the model group， the high-dose and medium-dose groups of Hei Xiaoyaosan could down-regulate the expressions of PTEN， BCL2L11 and MAPK1 mRNAs （P<0.01）， up-regulate the expressions of p-PI3K， p-Akt and Bcl-2 proteins （P<0.01）， and down-regulate the protein expressions of PTEN， Bax and cleaved Caspase-3 （P<0.05， P<0.01）. ConclusionHei Xiaoyaosan may regulate PI3K/Akt signaling pathway by down-regulating expressions of key genes such as PTEN， BCL2L11 and MAPK1， and thus improve the learning and memory abilities of insomnia rats with liver depression syndrome.
