This experiment was conducted to study the effects of replacing feed protein by Herme-tia illucens larvae meal on immune function,intestinal morphology and microflora of Sichuan white geese.A total of 64 healthy 1-day-old Sichuan white geese were randomly allocated into 4 groups with 4 replicates in each group and 4 geese in each replicate,namely the control group,the 2％HILM,4％HILM and 8％HILM groups fed diets contained 0％,2％,4％and 8％of HILM,re-spectively.The experimental period was 40 days.The results showed that compared with the con-trol group,8％HILM increased the levels of serum IgG1,IgG2a and complement C3,and the difference was statistically significant(P＜0.01).4％HILM significantly increased the expression level of CD4(P＜0.05),and 8％HILM significantly increased the expression level of IL-10(P＜0.05).The ratio of villus length to crypt depth(VH/CD)in the jejunum and ileum in 4％HILM group was significantly increased(P＜0.05).The SIgA level of jejunum was significantly increased in all HILM replacement groups(P＞0.05).The abundance of Bacteroides in 4％HILM group were extremely significantly increased(P＜0.01),and the abundance of Bilophila and Bilophila wadsworthia were significantly decreased in all HILM replacement groups(P＜0.05).In conclu-sion,HILM can enhance the immune function of Sichuan white geese,improve the intestinal mor-phology of jejunum and ileum,enhance the local mucosal immunity of jejunum,increase the abun-dance of beneficial bacteria in cecum and decrease the abundance of harmful bacteria in cecum,and protect intestinal health.

Objective To analyze the distribution characteristics of the single nucleotide polymorphism (SNP) site rs76206423 in the promoter region of the interleukin-2 receptor (IL-2R) β gene among Han males in a high radiation background area (HBRA) in Yangjiang City. Methods A total of 48 male participants from Tangkou Town, Yangxi County, Yangjiang City (HBRA group), and 51 male participants from Hengpo Town, Enping City (control group) were selected as the research subjects using the random number table method. Peripheral venous blood samples of participants from both groups were collected, and genomic DNA was extracted. The genotyping and allele frequency distribution of the rs76206423 (A/G) site in the IL-2R β promoter region was detected among the participants in both groups using the SNP detection method. The difference of allele frequencies between population in HBRA group and five area of East Asia, South Asia, Africa, Europe, and the Americas published in the Human Genome Project database from National Center for Biotechnology Information were analyzed. Results The allele frequencies of rs76206423 of population in both groups conformed to Hardy-Weinberg equilibrium (P>0.05). In the HBRA group, the AA genotype was predominant (64.6%), while the AG genotype was the most common in the control group (51.0%), with a significant difference (P<0.05). Population in both groups showed a predominance of the variant allele A (78.1% and 72.5%, respectively), with no significant difference (P>0.05). The frequency of the G allele of rs76206423 in the population in HBRA group was higher than those in South Asian, African, European, and American populations (all P<0.01), but showed no significant difference compared with East Asian populations (P>0.05). Conclusion In the Han male population from the HBRA in Yangjiang City, the rs76206423 site in the IL-2R β gene promoter region is predominantly composed of the wild-type A allele and AA genotype, indicating genetic stability and a relatively high degree of variation at this locus.

To explore the effect of Macleaya cordata extract(MCE)on growth performance and serum biochemistry of Sichuan White Geese,and to analyze its mechanism of action by network pharmacology and molecular docking technology combined with animal experiments verification.A total of 90 1-day-old healthy goslings were randomly divided into 5 groups with 18 goslings per group after 5 d of adaptive feeding.The control group(CON)was fed with basal diet,the antibiotic group(CTC)was supplemented with 450 mg/kg chlortetracycline premix,and the low MCE group(MCEL),medium MCE group(MCEM)and high MCE group(MCEH)were supple-mented with 200,300 and 400 mg/kg MCE,respectively.The experimental period was 21 d.On the basis of the above experiments,Network pharmacology and molecular docking technology were used to predict the core targets and signaling pathways of MCE to promote geese growth from the levels of antioxidant,immune and apoptosis,and the expression levels of the core target genes were detected by Real-time fluorescence quantitative PCR.The results showed that compared with the CON group,MCE supplementation could increase the average daily weight gain,decrease the ratio of feed to gain,significantly increase the contents of serum GH,T3,T4,TP and ALB(P＜0.05),and significantly decrease the contents of serum AST and TG(P＜0.05).Network pharmacology analysis predicted 2 active ingredient and 237 active ingredient targets,and concluded that the mechanism of MCE promoting the growth of Sichuan White Geese may be related to the role of 5 key targets such as SRC,HSP90AA1,CASP3,ESR1 and MAPK14,and the action of MAPK,apop-tosis and other signaling pathways.Molecular docking results showed that the active ingredients of sanguinarine and chelerythrine in MCE could act through MAPK14.The validation results of core targets showed that MCE could significantly reduce the mRNA expression levels of CytC,CASP2,CASP3 and CASP9 in spleen(P＜0.05)and significantly increase the mRNA expression levels of Mcl-1(P＜0.05).These results indicated that MCE could promote the growth performance of Si-chuan White Geese by regulating apoptosis,promoting the secretion of serum growth-related hor-mones and improving biochemical indicators.

Objective To observe the value of pseudo-continuous arterial spin labeling(PCASL)MRI for evaluating renal function in patients with renal occupying lesions.Methods Totally 56 patients with single renal occupying lesion were retrospectively enrolled.The left and right side kidneys were divided into normal renal function group(normal group,30 ml/min)and damaged renal function group(damaged group,＜30 ml/min)according to glomerular filtration rate(GFR)measured with 99Tcm-DTPA dynamic renal imaging,respectively.The total renal blood flow(tRBF)and cortical renal blood flow(cRBF)were calculated using total nephrometry and cortical nephrometry based on PCASL MRI,respectively,then GFR,tRBF and cRBF were compared between groups on the same side.Receiver operating characteristic curve was drawn,and the area under the curve(AUC)was calculated to evaluate the efficacy of tRBF and cRBF for assessing unilateral renal injury.Pearson correlation analysis was performed to observe the correlations of tRBF and cRBF with GFR.Results GFR,tRBF and cRBF in left/right damaged group were all significantly lower than those in ipsilateral normal group(all P＜0.05).AUC of tRBF and cRBF for assessing left renal injury was 0.823 and 0.813,respectively,being not significantly different(P＞0.05).AUC of tRBF and cRBF for assessing right renal injury was 0.940 and 0.922,respectively,being not significantly different(P＞0.05).No obvious correlation of bilateral tRBF nor cRBF with GFR was found(all P＞0.05).Conclusion PCASL MRI could effectively evaluate renal function in patients with renal occupying lesion,and the efficacy of total nephrometry was comparable to that of cortical nephrometry.

Soluble growth stimulating express gene 2(sST2)is a member of Toll/IL-1 receptor superfamily.sST2 plays an important role in the occurrence and development of respiratory diseases in children.Under normal circumstances, the concentration of sST2 in serum is very low, but the level of sST2 in serum of children with respiratory diseases such as bronchial asthma and community-acquired pneumonia increased significantly.sST2 blocks the IL-33 signaling pathway in airway inflammation, so serum sST2 levels can predict the severity of childhood asthma.sST2 can also be used as a prognostic marker of community-acquired pneumonia.This paper reviews the mechanism, clinical characteristics and prognosis of sST2 in children with asthma and community-acquired pneumonia, so as to lay a foundation for guiding clinical identification and treatment of respiratory diseases in children.
