Objective The aim of this study was to explore the values of IHP standard visual judgment,deauville(5-porint scoring and 5-PS)and maximum standard uptake rate(△SUVmax)image methods in the evaluation of early-and mid-term sensi-tivity determination and prognosis in malignant lymphoma patients. Methods A total of 51 patients with lymphoma who met the in-clusion criteria were selected for retrospectively analyses. PET/CT images of patients were analyzed by IHP standard visual judgment and deauville five-point methods. The△SUVmax value of the patient in the early and middle stages of treatment was calculated be-fore treatment, and the optimal cut-off value of PET/CT for early- and mid-term sensitivity determination and prognosis of evalu-ation△SUVmax was obtained by ROC curve. The differences between the diagnostic efficiencies of three methods were compared. The Kaplan-Meier analysis and Cox proportional hazard regression model were used for univariate and multivariate analyses. Results The results of ROC curve analysis showed that PET/CT had the best diagnostic efficiency when△SUVmax was 56. 95% . IHP stand-ard visual judgment,deauville quintile and△SUVmax methods could obtain high sensitivity and negative predictive values for the ear-ly-term treatment of lymphoma treatment. The positive predictive values and accuracy of △SUVmax method were higher than other two methods. Conclusion IHP standard visual judgment,deauville 5,and △SUVmax have high clinical values in the evaluation of early and middle stage of lymphoma treatment and prognosis. They can be used as independent risk factors for prognosis.

It is necessary to explore potent therapeutic agents via regulating gut microbiota and metabolism to combat Parkinson's disease(PD).Dioscin,a bioactive steroidal saponin,shows various activities.How-ever,its effects and mechanisms against PD are limited.In this study,dioscin dramatically alleviated neuroinflammation and oxidative stress,and restored the disorders of mice induced by 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine(MPTP).16 S rDNA sequencing assay demonstrated that dioscin reversed MPTP-induced gut dysbiosis to decrease Firmicutes-to-Bacteroidetes ratio and the abundances of Enterococcus,Streptococcus,Bacteroides and Lactobacillus genera,which further inhibited bile salt hy-drolase(BSH)activity and blocked bile acid(BA)deconjugation.Fecal microbiome transplantation test showed that the anti-PD effect of dioscin was gut microbiota-dependent.In addition,non-targeted fecal metabolomics assays revealed many differential metabolites in adjusting steroid biosynthesis and pri-mary bile acid biosynthesis.Moreover,targeted bile acid metabolomics assay indicated that dioscin increased the levels of ursodeoxycholic acid,tauroursodeoxycholic acid,taurodeoxycholic acid and β-muricholic acid in feces and serum.In addition,ursodeoxycholic acid administration markedly improved the protective effects of dioscin against PD in mice.Mechanistic test indicated that dioscin significantly up-regulated the levels of takeda G protein-coupled receptor 5(TGR5),glucagon-like peptide-1 receptor(GLP-1R),GLP-1,superoxide dismutase(SOD),and down-regulated NADPH oxidases 2(NOX2)and nu-clear factor-kappaB(NF-κB)levels.Our data indicated that dioscin ameliorated PD phenotype by restoring gut dysbiosis and regulating bile acid-mediated oxidative stress and neuroinflammation via targeting GLP-1 signal in MPTP-induced PD mice,suggesting that the compound should be considered as a prebiotic agent to treat PD in the future.

Dirofilaria immitis (heartworm) infections affect domestic dogs, cats, and various wild mammals with increasing incidence in temperate and tropical areas. More sensitive antibody detection methodologies are required to diagnose asymptomatic dirofilariasis with low worm burdens. Applying current transcriptomic technologies would be useful to discover potential diagnostic markers for D. immitis infection. A filarial homologue of the mammalian translationally controlled tumor protein (TCTP) was initially identified by screening the assembled transcriptome of D. immitis (DiTCTP). A BLAST analysis suggested that the DiTCTP gene shared the highest similarity with TCTP from Loa loa at protein level (97%). A histidine-tagged recombinant DiTCTP protein (rDiTCTP) of 40 kDa expressed in Escherichia coli BL21 (DE3) showed immunoreactivity with serum from a dog experimentally infected with heartworms. Localization studies illustrated the ubiquitous presence of rDiTCTP protein in the lateral hypodermal chords, dorsal hypodermal chord, muscle, intestine, and uterus in female adult worms. Further studies on D. immitis-derived TCTP are warranted to assess whether this filarial protein could be used for a diagnostic purpose.

Baylisascaris schroederi,a roundworm(ascaridoid)parasite specific to the bamboo-feeding giant panda(Ailuropoda melanoleuca),represents a leading cause of mortality in wild giant panda populations.Here,we present a 293-megabase chromosome-level genome assembly of B.schroederi to infer its biology,including host adaptations.Comparative genomics revealed an evolutionary trajectory accompanied by host-shift events in ascaridoid parasite lineages after host separations,suggesting their potential for transmission and rapid adaptation to new hosts.Genomic and anatomical lines of evidence,including expansion and positive selection of genes related to the cuticle and basal metabolisms,indicate that B.schroederi undergoes specific adaptations to survive in the sharp-edged bamboo-enriched gut of giant pandas by structurally increasing its cuticle thickness and efficiently utilizing host nutrients through gut parasitism.Additionally,we characterized the secretome of B.schroederi and predicted potential drug and vaccine targets for new control strategies.Overall,this genome resource provides new insights into the host adaptation of B.schroederi to the giant panda as well as the host-shift events in ascaridoid parasite lineages.Our findings on the unique biology of B.schroederi will also aid in the development of prevention and treatment measures to protect giant panda populations from roundworm parasitism.

This study aimed to obtain the first national estimate of the prevalence of autism spectrum disorder (ASD) in Chinese children. We targeted the population of 6 to 12-year-old children for this prevalence study by multistage convenient cluster sampling. The Modified Chinese Autism Spectrum Rating Scale was used for the screening process. Of the target population of 142,086 children, 88.5% (n = 125,806) participated in the study. A total of 363 children were confirmed as having ASD. The observed ASD prevalence rate was 0.29% (95% CI: 0.26%-0.32%) for the overall population. After adjustment for response rates, the estimated number of ASD cases was 867 in the target population sample, thereby achieving an estimated prevalence of 0.70% (95% CI: 0.64%-0.74%). The prevalence was significantly higher in boys than in girls (0.95%; 95% CI: 0.87%-1.02% versus 0.30%; 95% CI: 0.26%-0.34%; P < 0.001). Of the 363 confirmed ASD cases, 43.3% were newly diagnosed, and most of those (90.4%) were attending regular schools, and 68.8% of the children with ASD had at least one neuropsychiatric comorbidity. Our findings provide reliable data on the estimated ASD prevalence and comorbidities in Chinese children.
